Results show that the huff-puff design is a good diagnostic test for matrix diffusion. The two-well doublet design averages over a large volume and corrects for the extreme sensitivity to spatial heterogeneities of the single well converging test, but requires prior knowledge of presence or absence of matrix diffusion to give reliable estimate of transport parameters. Results of this study demonstrate that using a suite of different tracer designs is important to reduce the uncertainty in association with solving the inverse problem of tracer test interpretation to characterize transport in fracture rocks.

In the processes of imbibition and drainage, the connectivity of each phase at a particular capillary pressure can be sought out by the priority-first search algorithm of graph theory. Then, the flow path in each phase can be identified, and flow equations can be established and solved in an optimal manner. It was observed that in a simulated rough fracture, a few flow "channels" can dominate the permeability of the whole system. C1 SANDIA NATL LABS, DEPT GEOMECH 6117, ALBUQUERQUE, NM 87185 USA.

The 2-dimensional, saturated fracture flow and transport code FRACTRAN was used to conduct the simulations. Seven parameters were considered: matrix hydraulic conductivity, matrix porosity, retardation of the matrix, gradient of the flow field, fracture retardation, fracture aperture, and fracture probability (which incorporates fracture spacing and fracture length). A Latin-hypercube design was used to select a matrix of parameter values that minimized correlations among the design parameters. The results were summarized by examining least square fit of the relationship between the seven parameters anti 50% breakthrough time and spread of the breakthrough curves, with nearly identical results. The matrix parameters, in particular hydraulic conductivity and porosity, had the greatest effect. As expected, fracture probability was nearly equivalent in importance. These results indicate that field characterization in fractured porous media should not only emphasize fracture location, which strongly influences directions of contaminant transport, but also matrix properties, which have a major influence on contaminant residence times and breakthrough concentrations.

Spatial scales for such problems vary from meters to kilometers with temporal scales from months to tens of thousands of years. Because such scales often preclude direct physical exploration of system response and detailed site characterization, we are regularly forced to use our understanding (or misunderstanding) of the underlying physical processes to predict large scale behavior. It is essential that conceptual models used as the basis for prediction be firmly grounded in physical reality. In this paper, we provide examples of how recent advances in understanding of small-scale processes within discrete fractures may influence the behavior of fluid flow in fracture networks and ensembles of matrix blocks sufficiently to impact the formulation of intermediate-scale effective media properties. We also explore, by means of a thought experiment, how these same small-scale processes could couple to produce a large-scale system response inconsistent with current conceptual models of now through unsaturated, fractured rock.

An individual irregularly-shaped matrix block can be modeled with reasonable accuracy using the results for a spherical matrix block, by defining an effective radius ($) over tilde a = 3V/A, where V is the volume of the block and A is its surface area. In the early-time regime, a collection of spherical blocks of different sizes can be replaced by an equivalent spherical block with a radius of a(eq) = < a(-1) >(-1), where the average is taken on a volumetrically-weighted basis. In the long-time limit, where no equivalent radius can rigorously be defined, asymptotic expressions are derived for the cumulative uptake as a function of the mean and the standard deviation of the radius distribution function, for both normal and lognormal radius distributions.

The improvement involves the use of a very strong correlation between natural radiocarbon and dissolved silica This method is applied to radiocarbon measurements made on samples collected during the Geochemical Ocean Sections Study (GEOSECS), Transient Tracers in the Ocean (TTO) and South Atlantic Ventilation Experiment (SAVE) expeditions. On the basis of this new separation we provide not only an estimate of the global inventory of bomb C-14 at the time of the GEOSECS survey but also the distribution of bomb radiocarbon along four thermocline isopycnals in each ocean. We also document the evolution of the bomb C-14 inventory and penetration along thermocline isopycnals in the North Atlantic Ocean between the times of the GEOSECS (1972-2973) and TTO (1980-1982) surveys and in the South Atlantic Ocean between the times of the GEOSECS (1973) and SAVE (1987-1989) surveys. In addition, we show that the bomb tritium to bomb C-14 ratio (expressed in the tritium unit (TU) 81 units/100 parts per thousand) for waters entering the thermocline of the northern hemisphere is about 9 times higher than for those entering the southern hemisphere thermocline. This contrast offers long-term potential as an indicator of inter-hemispheric transport of upper ocean waters. C1 OAK RIDGE NATL LAB,DIV ENVIRONM SCI,OAK RIDGE,TN 37831.

Translocations and dicentrics were distinguished by use of a pan-centromeric probe. A total of 41,151 metaphases were analyzed at doses below 0.2 Gy. The linear ''take-off'' slope of the linear-quadratic dose-response curve for translocations, i.e., the alpha coefficient, was measured to be 0.023 +/- 0.005 translocations per cell per Gy. This alpha coefficient is more precise than previously measured. Because the alpha coefficient is the dominant contributor to the translocation frequency induced by low-level exposures, the results presented here will substantially reduce uncertainties in biodosimetry estimates obtained for stable translocations.

The method employs the enhanced three-point Dixon technique for producing pure fat and pure water MR images of the human body. The MR images are used to define the geometry and composition of the scattering media for transport calculations using the general-purpose Monte Carlo code MCNP, Version 4. A sample case for developing the new method utilizing an adipose/muscle matrix is compared with laboratory measurements. Verification of the integrated MCNP method has been done for a specially designed phantom composed of fat, water, air, and a bone substitute material. Implementation of the MRI-MCNP method is demonstrated for a low-energy, lung counting ia vivo measurement system. Limitations and solutions regarding the presented method are discussed.

However, if the biological response expressed at the cellular level is similarly plotted against the average absorbed dose expressed at the organ-organism level, a linearly proportional, ''non-threshold'' function is obtained. To explain this marked difference in curve shape, the absorbed dose at the organ level in terms of its meaning at the cellular level was examined, and both dose and response were put on the latter level. The result is consistent with the conclusion that absorbed dose at the organ-organism level can be treated, at the cellular level, as the product of two quantities: 1) the mean energy concentration or dose in a cell from a deposition event, i.e.,''hit size'' (the frequency-averaged specific energy in a reference cell target), and 2) the number of deposition events, or ''hits,'' on the exposed cells. When the mean hit size for a given radiation remains constant, and the number of hits is increased, the total number of responses follows a linearly proportional ''hit number response function.'' However, if the hit number is held constant or normalized to a given value, and the hit size is varied, the resulting probability of cell response again plots as the apparently sigmoid curve mentioned above, which has been termed the ''hit size effectiveness function.'' With decreasing hit size, the probability of a cellular response appears to decrease asymptotically, and become indistinguishable from zero before zero dose is reached. It follows from this inherent relationship between the two kinds of functions that a sufficiently extensive set of data on a population of cells permits either type of function to be produced at will. These findings bear on the interpretation of the ''linear, non threshold'' hypothesis. C1 TEL AVIV UNIV, SCH PHYS, IL-69456 TEL AVIV, ISRAEL. UNIV ARIZONA, DEPT RADIOL, TUCSON, AZ 85724 USA.

Subsamples of crops were prepared for human consumption before analysis to determine the extent of any loss. Plant:soil concentration ratios (dry basis) ranged from 0.22 to 6.82, values which were substantially higher than those used in generic assessment models.

The method requires two counting periods for each sample: a 1-min count as soon as the sample has been drawn into a scintillation cell, followed by a 5- or 10-min count at least 5 min after the soil gas sample has been obtained. The Rn-222 concentration is determined from the second count, The counts in the first counting period (1-min) due to Rn-222 and its progeny are calculated from the known Rn-222 concentration and then subtracted from the total counts obtained in the first counting period. The remaining counts are due to Rn-220 and its progeny and are used to calculate the Rn-220 concentration. The overall uncertainty when using this method to measure typical soil gas Rn-220 and Rn-222 concentrations [> similar to 5 kBq m(-3) (130 pCi L(-1))] was determined to be 19.8% and 10.8% (90% confidence levels), respectively, from analyses of duplicate field measurements. The lowest Rn-220 concentrations that can be measured using this technique while maintaining an overall error no greater than about 30% is similar to 500 Bq m(-3) (13 pCi L(-1)), assuming an approximately equal Rn-222 concentration. The Rn-220 measurement uncertainty at this concentration level decreases to similar to +/- 20% if at least three measurements sampled in series are arithmetically averaged. The uncertainty in the(220)Rn measurement at low levels is proportionately affected by the relative concentration of Rn-222 present.

From 76-79% of the dietary volume was the salt marsh periwinkle (Littorina irrorata); crabs (Uca pugnax, Sesarma reticulatum, and Callinectes sapidus), barnacles (Balanus), and clams (Polynesoda caroliniana) constituted the remainder. Dietary partitioning is related to the ontogenetic niche of terrapins. Sexual dimorphism occurs in terrapins with females having larger heads and bodies than males. Terrapins with large head widths ingest significantly larger periwinkles and a wider diversity of prey than terrapins with small head widths. Dietary overlap between males and females is greatest when females are small and decreases as females develop larger enlarged heads. Sexual dimorphism in terrapin trophic structures appears to be partially driven by ecological divergence through resource partitioning. High tides permit terrapins to forage aquatically in upper reaches of the salt marsh. Prey size and distribution are variable and changing tidal heights affect the spatiotemporal availability of prey to foraging terrapins. Divergent foraging strategies for terrapins of different head widths may result in habitat partitioning. Food accessibility rather than food abundance may be a limiting factor for terrapins in areas of high tidal variability. Terrapins are clearly prominent but unrecognized macroconsumers in salt marsh ecosystems. C1 SAVANNAH RIVER ECOL LAB,AIKEN,SC 29802.

Three IgG(1) antibodies (Rpt 1, 2, and 3) were capable of detecting 2 ng of receptor using peroxidase-goat anti-mouse IgG antibody conjugate on a protein blot. Monoclonal antibody Rpt 9 exhibited the greatest ability to immunoprecipitate the nondenatured 9S form of the Ah receptor and to visualize the AhR on liver tissue sections using immunohistochemical techniques, All of the monoclonal antibodies produced were able to bind to the mouse, rat, and human Ah receptor. These monoclonal antibodies should be useful in a wide number of applications in the study of Ah receptor biochemistry.

The model is constructed by combining a microscopic model used in the semi-classical approximation for dielectric media and the particle model developed for plasma simulations, The carrier wave frequency is retained in the simulation so that not only the envelope of the soliton but also its phase can be followed in time. It is shown that the model may be useful for studying pulse propagation in the dielectric media. RP PRINCETON UNIV, PLASMA PHYS LAB, POB 451, PRINCETON, NJ 08543 USA.

The measurements show that spontaneous emission from the cavity perimeter (lateral emission) is overwhelmingly larger than the same emanating along the lasing direction (axial emission). A model for lateral and axial spontaneous emission from microcavities is postulated based on one- and two-dimensional vacuum electromagnetic field confinement, respectively. A new cavity mode counting technique is developed and utilized to calculate the spontaneous emission initio. The resulting field configuration theory is in good agreement with the emission intensity measurements. C1 SANDIA NATL LABS,ALBUQUERQUE,NM 87185.

The novel passive antiguide region surrounding the active region is demonstrated to be a highly effective transverse mode and polarization mode selection mechanism. A stable single fundamental mode at high currents has been achieved experimentally for laser aperture as large as 16 mu m diameter. In addition, very low threshold current of 0.8 mA and current density of 490 A/cm(2) are achieved with 8 and 32 mu m diameter VCSEL's, respectively. A detailed numerical two- and three-dimensional analysis was performed using the beam propagation method. The modal losses were calculated as a function of the cladding refractive index and the laser size. Quantitative results leading to approximate formulae have been achieved. The high mode selectivity obtained from the numerical analysis is in good agreement with the experimental results we have achieved. C1 SANDIA NATL LABS,ALBUQUERQUE,NM 87185.

We apply a model which includes bandstructure, band-filling and many body effects in a consistent manner, as well as leakage current effects, to evaluate the effect of strain and quantum confinement on threshold current. We find that leakage current becomes increasingly important for shorter wavelength devices, comprising more than half of the total current for a laser emitting at 620 nm. The reduction of threshold current with increasing compressive strain is clearly demonstrated and the dependence of threshold current density on quantum well width is found to be greater for shorter wavelength lasers.

Such applications include transit system electric support and frequency stablization of transmission lines. When cycled frequently, the thermal load to the cooling system is dominted by eddy current or ac losses. In systems with small energy storage capacity, the refrigeration system cost associated with sc losses can dominate the total system cost if the coil uses conventional superconductor and liquid helium cooling. If high temperature superconductors operating at liquid nitrogen temperature could be used then significant savings in refrigeration cost and hence, system cost, are possible. The HTS conductor does require a twisted configuration to realize these savings. Analysis and results for SMES systems ranging in size from 1 MJ/1 MW to 10 MJ/10 MW and operating at up to 1 Hz are presented. C1 SANDIA NATL LABS,ALBUQUERQUE,NM 87185.

If this constraint is removed, then smaller systems structurally reinforced with cold mass are more cast effective than support with warm mass. Higher field is also more advantageous and thus the bore of a 20 MWh magnet is an order of magnitude smaller than an ETM. Both aluminum and stainless steel support were considered and the weight of 1-100 MWh systems were determined. The cost of the SMES magnet scales as 0.5 power of stored energy. The cross over in stored energy where magnets supported by warm structure becomes cheaper was also determined. RP LUBELL, MS (reprint author), OAK RIDGE NATL LAB,OAK RIDGE,TN 37831, USA.

Since the closed loops formed In such an arrangement could lead to eddy current heating or instability in changing fields,,one of the coils was also tested in helium gas, in fields ramped at rates of up to 1.5 T/s, For these quasi-adiabatic tests, at each temperature the transport current was set just below the critical value for a preset static field of 3.3 or 4.9 T. The field was then rapidly ramped down to zero, held for 20 sec, and then ramped back up to the original value. The maximum observed temperature transient of about 1.7 K occurred at 9 K, for a field change of 4.75 T. The temperature transients became negligible when the sample was immersed In liquid helium. Above 30 K, the transients 1 K. These results give confidence co-wound HTSC coils are stable In a rapidly-ramped magnetic field, without undue eddy current heating.

Sensitive miniature Hall sensors and small pick-up coils placed around Cable-in-Conduit Conductor were used to measure local magnetic fields and field derivatives associated with currents in the cable. Using this method both fast jumps and slow changes in local magnetic fields at different conditions were observed. Fast jumps occured during ramping background magnetic field and may indicate a fast current redistribution processes. Slow changing of local fields may be associated with current loops closed through the current lead joints. Such current loops may also indicate the non-uniformity of current distribution in the cable strands. The new method is a promising tool for future investigations of stability of multistrand cables.

The short IQZs approximate ramp-rate induced heating, and the long IQZs approximate heating from a plasma disruption. These IQZs are centered in the bore inner leg of the double pancake, where the operating field and temperature are maximum. Energy margin stability curves are plotted as a function of current. The stability of the 10 cm IQZ differs from that for the 20 cm IQZ by less than 20%. Similarly the stability of the 2.28 m IQZ differs from that for the 4.53 m IQZ by less than 20%. However the stability of the short IQZs (10 and 20 cm) is about twice as high as that of the long IQZs (2.28 and 4.53 m). The friction in the long IQZs prevents the conversion of heat to work by helium expansion during the pulse. At the 33.5 kA design current, the minimum calculated stability margin with short IQZs is 390 mJ/cc. The minimum calculated stability margin with long IQZs is 205 mJ/cc. A comparison the stability margin with the available enthalpy (short IQZs) and with the available internal energy (long IQZs) shows that the conductor utilizes the available helium energy well. The energy margin stability curve is generally divided into two regions. The regions can be characterized on the basis of a decrease or an increase in heating after the initiating heat pulse during a marginal quench. The low current ''well-cooled'' region exists when the heating rate during the pulse is greater than the Joule heating after the pulse. Since the heating rate decreases, the energy margin is high. The high current ''ill-cooled'' region exists when the heating rate during the pulse is less than the Joule heating after the pulse. Since the heating rate increases, the energy margin is low. The ''limiting current'' occurs when the heating rate during the pulse is the same as the Joule heating after the pulse. The TPX/TF conductor, with its high critical to operating temperature difference (5.8 K at design conditions) and the high 2.5/1 copper/superconductor ratio, can operate stabily with significant Joule heating during the pulse, even at high currents. In the evaluation of a well-cooled.or an ill-cooled condition, this Joule heating should be included in the strength of the initiating pulse. When this is done for the TPX/TF conductor, the limiting current approaches the critical current, explaining why the stability curves are entirely in the well-cooled region. The important result is that the conductor does not exhibit a large decrease in energy margin to an ill cooled region until the current approaches the critical current.

The calculated stability curves display the large decrease in energy margin from the low current and high energy margin ''well-cooled'' stability region, to the high current and low energy margin ''ill-cooled'' region that was determined experimentally. The calculated ''limiting current'' of 250 A (boundary between the ill-cooled and well-cooled regions) also agrees with experiment, The multi-valued stability margins measured for lengths of 3.1 and 3.8 m could not be obtained by the computer model. Excluding the multiple stabilities, the calculated margins are generally 30% lower than the experimental values. The decrease in energy margin in the ill-cooled region was found to be due to the low critical to operating temperature difference (2.2 K at 250 A). This prevents an initiating pulse in the ill-cooled region from being able to generate significant Joule heating without quenching, limiting the energy margin. C1 UNIV WISCONSIN,MADISON,WI.

The coefficient of friction mu for such storage systems is derived as a function of bearing parameters and is shown to be an appropriate figure of merit to describe bearing losses. Analysis shows that values of mu < 10(-6) enables flywheels. A vacuum-chamber experimental apparatus has been constructed to measure values of mu for various experimental bearing designs. Experimental values for mu at low velocity have been as low as 3 x 10(-7) for an 89-mm-diameter ring permanent magnet stably levitated over an array of melt-textured Y-Ba-Cu-O.

This magnet will be used to store muons for a planned ultra-precise measurement of their anomalous magnetic moment g-2. This measurement requires a magnetic field uniformity of 1 PPM with a knowledge of the field over the muon orbits to 0.1 PPM. The methods built into the design to produce ultra-high field uniformity will be described, Large deviations from the ideal circularly symmetric uniform shape of the iron nux path are required to accommodate transfer lines and superconducting current leads, as well as apparatus for beam injection, Shimming methods to correct for the perturbations due to these large holes will be presented. The pole pieces consist of 36 closely fitting 10 degrees are sections butted together to produce a very good approximation to a continuous 360 degrees ring magnet. However, in the case of a possible quench of the superconducting coils, significant eddy currents will be induced which will circulate within the confines of each 10 degrees pole piece. At the great precision required, these eddy currents may leave very small but significant aberrations in the field even after they decay away, because of slight changes in the orientation of the magnetization. Surface coil possibilities to correct for this effect will be described. RP DANBY, GT (reprint author), BROOKHAVEN NATL LAB,UPTON,NY 11973, USA.

The field within the inflector is designed to be nearly zero. The inflector bucks out the main dipole field, but generates little or no stray field of its own. A portion of the field that remains is the field that is generated by circulating currents in the inflector magnet superconductor. Because the magnetization field has a different structure from field generated by the transport current, the magnetization field can adversely affect the field quality within the muon storage ring good field region.

This inflector locally bucks out the 1.45 tesla storage ring dipole field, so that the muon beam enters the ring tangentially as close as possible to the equilibrium orbit. The g-2 experiment requires the knowledge of the magnetic field over the muon orbits to a precision of 0.1 ppm. The inflector has nested dipole coils of opposite polarity so that it cancels its external magnetic flux and generates very little stray field. Nevertheless the residual field would effect the homogeneity of the storage ring magnetic field. A method of using a multilayer SC composite sheet surrounding the inflector to further reduce the fringe field has been proposed. This sheet should prevent the stray field due to the inflector from affecting the field quality of the muon storage region. In developing this new type of air-core septum magnet, a shortened SC prototype inflector was built in Japan at KEK. It has been used for testing the superconducting performance (in KEK, BNL) and the fringe flux shielding (in BNL). Some of the test results are presented. C1 BROOKHAVEN NATL LAB,UPTON,NY 11973.

Interstrand contact resistance (R(c)) measurements supplemented these studies. R(c)s were deduced from the M-H determined eddy current loss as a function of ramp rate for four wires arranged in a rectangular geometry and put under a predetermined strain. It was found that (1) the dominant factor which determines the R(c) for uncoated strands is the level of surface oxidation (even for solvent cleaned strands); (2) strands can be de-oxidized either by an HCl etch or a vacuum anneal; and (3) strand coatings add significantly to the contact resistances of un-oxidized strands. It is concluded that contact resistance, and hence cable loss is largely determined by the surface condition of the strands rather than the area (''spoon size'') of the interstrand contact.

Another important feature of the current lead design is the use of high Jc thick film superconductors deposited on a non-conducting substrate to reduce the conductive heat leak through the lower portion of the lead. Two flexible electrical conductors are incorporated to accommodate handling, assembly and the dissimilar expansion coefficients of the various materials.

Designs are considered Chat are inherently safe from burnup, even if the lead enters the normal state, The effect of a tapered lead that takes advantage of the increase in critical current density with decreasing temperature will decrease helium boiloff by about a factor of two for an area ratio of four, A new concept, in which Ag powder is distributed in increasing concentration from the cold end to the hot end of a sintered YBCO lead, is shown to have comparable performance to that of leads made with Ag-alloy sheaths. Performance of the best inherently safe designs is about one order of magnitude better than. that of optimized nonsuperconducting leads. BSCCO leads with Ag-alloy sheaths show improved performance for Au fractions up to approximate to 3%, after which increases in Au fraction yield negligible improvement in performance.

The two outer solenoids, which are 15.1 meters in diameter, share a common cryostat, The two inner solenoids, which are 13.4 meters in diameter, are in separate cryostats. The two 24 turn inner solenoids are operated at an opposite polarity from the two 24 turn outer solenoids. This generates a dipole field between the inner and outer solenoids. The flux between the solenoids is returned through a C shaped iron return yoke that also shapes the dipole field. The integrated field around the 14 meter diameter storage ring must be good to about 1 part in one million over the 90 mm dia. circular cross section where the muons are stored, averaged over the azimuth. When the four solenoids carry their 5300 A design current, the field in the 18 centimeter gap between the poles is 1.45 T. When the solenoid operates at its design current 5.5 MJ is stored between the poles. The solenoids were wound on site at Brookhaven National Laboratory. The cryostats were built around the solenoid windings which are indirectly cooled using two-phase helium. C1 UNIV CALIF BERKELEY,LAWRENCE BERKELEY LAB,BERKELEY,CA 94720.

The principal component is an extrinsic Fabry-Perot interferometer to determine localized strain and stress in coil windings. The system can be used either as a sensitive relative strain measurement system or as an absolute strain detector. Combined, one can monitor the mechanical behaviour of the magnet system over time during construction, long time storage and operation. The sensing mechanism is described, together with various tests in laboratory environments. The test results of a multichannel test matrix to be incorporated first in the dummy coils and then in the final version of a 13T Nb3Sn accelerator dipole magnet are presented. Finally, the possible use of this system as a quench localization system is proposed. C1 UNIV TWENTE, CTR APPL SUPERCONDUCT, 7500 AE ENSCHEDE, NETHERLANDS.

Two types of developed full-scale conductors were tested under the US-Japan Collaboration Program at the Fusion ENgineering International eXperiment (FENIX) Test Facility in the Lawrence Livermore National Laboratory(LLNL) which has a pair of 13-T, 320-mm bore large split magnets and a more than 40-kA power supply. Each conductor consists of around 700 bronze processed (NbTi)3Sn strands and a titanium conduit. The superconducting performance tests such as current sharing temperature(Tcs) measurement test were carried out. Through a series of experiments, it was confirmed that the conductor satisfied their designed temperature margin of 2 K or more at their rated condition. In this paper, the development of full-scale conductors is described and measured Tcs values are discussed. C1 LAWRENCE LIVERMORE NATL LAB,LIVERMORE,CA 94550.

A bellows helium pump is one possible way of providing helium flow to a magnet cooling system. Since the bellows type of helium pump is immersed in liquid helium, a superconducting linear motor drive appears to be an attractive option. This report describes a linear motor drive that employs oriented permanent magnet materials such as samarium-cobalt as the stator magnet system and a superconducting loud speaker voice coil type of drive as the armature of the linear motor.

A wind and react technique, followed by epoxy impregnation of the fiberglass insulated coils, was used, The problems identified with the use of Nb3Sn in earlier dipole magnets were investigated in a series of supplemental tests, This includes measurement of the degradation of Jc with transverse strain, cabling degradation, joint resistance measurements, and epoxy strength tests, In addition, coil assembly techniques were developed to ensure that adequate prestress could be applied without damaging the reacted Nb3Sn cable.

The four-layer ''cosine-theta'' magnet uses a wide cable (similar to 15 mm) that will undergo a 650 C reaction after each layer is wound. About 75 bronze spacers at the magnet ''ends'' separate the winding blocks in such a way that the stored strain energy in the cable is minimized and the integrated field harmonics are reduced. Wax prototypes of the designed spacers were made on a 5-axis milling machine. This method of rapid prototyping required no tooling and enabled us to produce a large number of different end spacers that can be physically inspected and repeatedly modified before final prototypes are made. Spacers were originally machined from wax billets which were later cast in bronze. RP CASPI, S (reprint author), UNIV CALIF BERKELEY,LAWRENCE BERKELEY LAB,BERKELEY,CA 94720, USA.

Coil signals were nulled against a neighbor to produce low-ripple signals that were sensitive to local flux changes. A low-microphonic signal was used as an event trigger. 2) Nulling improvements were made for the magnet's coil-imbalance signals for improved cross-correlation information. 3) A quench-propagation antenna was installed to observe current redistribution during quench propagation. It consisted of quadrupole/sextupole coil sets distributed at three axial locations within the bore of the magnet. Signals were interpreted in terms of the radius, angle, orientation, and rate of change of an equivalent dipole. The magnet was cooled to 1.8K to maximize the number of events. Twenty-four fast-motion events occurred before the first quench. The signals were correlated with the magnet-coil imbalance signals. The quench-propagation antenna was installed for all subsequent quenches. Ramp-rate triggered quenches produced adequate signals for analysis, but pole-turn quenches yielded such small signals that angular localization of a quench was not precise.

This oscillation is present in all components of the field and has a period that is equal to the transposition pitch of the superconducting cable. Such axial variations have been observed even in windings which are not carrying any transport current. A magnetic field was applied to a portion of a dipole winding using a second magnet, Axial oscillations were induced along the total length of the windings including the portion not in the applied field. The amplitude of these oscillations varied with the amount of inert winding inside the energizing magnet and with the angle of the applied field. These field variations could be completely eliminated in the external portion of the coil by heating a small section of the winding above the transition temperature.

If properly controlled, these grain boundaries can be used in various device applications, we have been able to reproducibly form 45 degrees [001] tilt grain boundary junctions in YBa2Cu3O7-x thin films, The films were grown on MgO substrates using a pregrowth substrate treatment. A low energy broad beam Argon ion source was used to irradiate a select region of (100) MgO substrates. The film on the milled portion of the substrate grows predominantly with a grain orientation rotated 45 degrees about the c-axis with respect to the grain on the unmilled portion, Backscattered electron Kikuchi patterns have been used to confirm that the rotation occurs across the entire milled portion of the substrate. Transport properties of these films are discussed and related to high resolution electron microstructural and microchemical analyses of the grain boundaries. This technique has potential use in device applications as a method for controlled grain boundary engineering. C1 NORTHWESTERN UNIV,DEPT MAT SCI & ENGN,EVANSTON,IL 60208.

However, the higher J(c) of the slow-cooled state does correlate with a sharper T-c transition, Experiments with ''two-powder'' tapes have produced similar results, These apparently anomalous results emphasize the Important role played by the connectivity of the polycrystalline core in determining J(c).

TEM examination showed that the grains were highly defected and that the grain boundaries were clean, The T-c was however low with an onset of 50K and a width of similar to 10K, Annealing studies were carried out with an aim to ''fully oxygenate'' the material and anneal out a minimal number of defects to obtain higher transition temperatures, at the same time retaining a significant defect density for enhanced flux-pinning, Magnetization measurements were performed after most anneals in order to evaluate intragranular and intergranular properties. Results indicate the presence of unusually high J(c)'s at low temperatures after the final anneal (T-c onset similar to 90 degrees K). The observations may be explained by highly superior intragranular properties coupled with increased local current loop size. C1 LEHIGH UNIV,DEPT MAT SCI & ENGN,BETHLEHEM,PA 18015.

The liquid phase is essential for microstructural and phase development of superconductors and is important in fabricating conductors with high critical current density, J(c). Tapes were fabricated by a powder-in-tube process and then placed in controlled-atmosphere furnace, During heat treatment, a magnetostrictive transducer launches a 140-kHz wave into the sample, and the relative change in acoustic velocity is then measured. A significant decrease in velocity was seen at the incongruent melting temperatures of Bi-based superconductors. In addition, Ag-clad tapes with Al2O3 and NaCl cores were used to validate the measurement technique. Advantages of this approach over other thermal analysis methods include In-situ analysis of final tape form, monitoring of isothermal liquid evolution, and control of volatile species such as Tl and Pb.

The effects of different intermediate pressing stresses during tape processing had dramatic effects on both the current-carrying capacity and the tape microstructure. Variation of pO(2) also led to differences in current-carrying capacity I-c as did a roll substituted for a press during tape processing. C1 SANDIA NATL LABS,ALBUQUERQUE,NM 87185.

The large resistance of the meander line effectively increased the electric field, or equivalently, resistivity sensitivity by two orders of magnitude. In moderate magnetic fields the critical current density is found to depend only on the component of the magnetic field normal to the ab planes owing to the highly anisotropic nature of the system. The resistivity versus temperature was measured as a function of magnetic field up to 18T. The linear resistivity is found to vanish in a manner consistent with the occurrence of a second order phase transition. The critical exponent v(z-1) is virtually field independent with a value 5.3 +/- 1 consistent with previous measurements of a three dimensional vortex glass transition in YBa2Cu3O7 and Bi2Sr2CaCu2O8. The critical regime is 10-15K wide in agreement with values for Bi2Sr2CaCu2O8 at high magnetic field. C1 LOS ALAMOS NATL LAB,NATL HIGH MAGNET FIELD LAB,LOS ALAMOS,NM 87545.

Homogeneous materials were obtaned with micron and submicron crystalline phases uniformly disprsed in an amorphous matrix. For Y123, the crystalline phases are identified by XRD as BaCu2O2 and Y2O3 when the melt-spinning temperature is below 1600 degrees C. At 1650 degrees C, the crystalline phases are Y4Ba3O9, BaCu2O2 and Y2O3. The phase composition of the solidified melt is directly related to the oxygen content of the melt and can be related to the equilibrium phase diagrams at lower oxygen partial pressures. Isothermal annealing in oxygen st temperatures 500 degrees C to 950 degrees C reveals that the crystallization sequence is: Y123 begins to form at 500 degrees C, Y123 with minor amount of Y2BaCuO5 at 800 degrees C, Y123 with very minor amount of: CuO at 900 degrees C, and single phase Y123 at 950 degrees C.

It was found that both microstructure and magnetization behavior strongly depend on the chemistry the grain size of the starting material. The carbon content and the melting behavior of the YBa2Cu3Ox powders seem to play an important role In the development of microstructure and flux-pinning behavior during melt-texturing. Carbon, which is existing in different amounts in all commercially available YBa2Cu3Ox powders and is also easily introduced during processing, was found to have the same detrimental influence on the grain boundaries of melt-processed materials as on the grain boundaries of sintered pellets. On the other hand an increase in the flux-pinning behavior could be found when carbon was present during the melting and resolidification process. Our results that the presence of carbon during the resolidification process results in the incorporation of precipitates and defects not only into the grain boundaries, but also into the bulk of YBa2Cu3Ox, leading to an increased intragrain critical current density. Initial experiments indicate that a similar effect might also be possible for Bi2Sr2CaCu2Oy. C1 UNIV ILLINOIS,DEPT MAT SCI & ENGN,URBANA,IL 61801. RHEIN WESTFAL TH AACHEN,D-52072 AACHEN,GERMANY.

It has been found that 123 experiences partial melting near 1010 degrees C during heating, and that crystallization takes place at a much lower temperature upon cooling, indicating a delayed nucleation process. A series of experiments has been conducted to search for the initial crystallization temperature in the YBa2Cu3Ox + liquid phase field. We have found that for slow cooling (1 degrees C/h), grain texturing for 123 can start as low as 960 degrees C.

These films were deposited onto <100> MgO substrates by off-axis sputtering using a custom fabricated multi-gun planar magnetron system. Each layer and the various combinations of materials were optimized for: epitaxial lattice match, crystal quality, film uniformity, electrical properties, and surface microstructure. In addition to the standard procedures commonly used to sputter deposit epitaxial oxide films, a variety of unique insitu and exsitu procedures were used to produce high quality multilayer devices, including: using a film nucleation temperature lower than the final film growth temperature, establishing the optimum substrate to target relationship, and timing of the oxygen anneal. Using a lower nucleation temperature when depositing the YBa2Cu3O7-x allowed us to dramatically improve the crystallinity and orientation of the superconductor on both unprocessed and ion-milled substrates. Completed multilayer devices consistently exhibited resistively shunted Josephson junction behavior in patterned bridges and SQUID's.

This can be achieved by either the refinement of the Nb3Sn grains due to the presence of a second phase or by the second phase itself pinning flux. If a bronze-type process is to be used a different addition than Zr is required since internal oxidation of Nb is not possible. The criteria for elements to be candidates for the APC approach are discussed. The results for one of the candidates (Ag) show that it is not incorporated into the Nb3Sn, however, its addition did increase the growth rate.

Such additives reduce the peritectic decomposition temperature of pure Bi-2212 by approximately 15-20 degrees C. Scanning electron microscopy (SEM) and optical microscopy on polished top and cross-sections revealed that the volume fraction of Bi-free phases was lower in the Bi-added specimens relative to those based on pore Bi-2212. In addition, it appeared that the Bi-added samples had improved grain alignment, which was confirmed by x-ray diffraction analysis. Magnetic hysteresis (at 5 K between +/- 5.5 T) and transport measurements (at 4.2 K) were performed on each specimen. These results showed that Bi-additions yielded superior magnetization critical currents, which is attributed to improved grain alignment and reduced secondary phases.

In an effort to understand the nucleation and growth of Tl-1223 as well as the formation of the ''colony'' microstructure, several sets of films quenched from various stages of the high-temperature tballination process were examined using electron microscopy, X-ray diffraction and Electron backscatter diffraction (EBSP). It is found that the crystallization of the 1223 phase is associated with formation of a liquid phase which contains significant amounts of all oxides, X-ray micro-diffraction measurements show that the 1223 phase crystallizes in an aligned manner. Studies of films very early into the thallination process show that local biaxial alignment or the formation of colonies starts to occur at the onset of 1223 crystallization. In addition, it appears that the structure within colonies is a function of the processing conditions employed. This presents the possibility for further optimization of the microstructure to attain improved superconducting properties. C1 GE CO, CORP RES & DEV, SCHENECTADY, NY 12301 USA.

The two methods examined were: 1) precursor Pb-Sr-Ba-Ca-Cu-O(Ag) powders sprayed as a colloidal ink onto a heated substrate; 2) precursor material deposited by electrodeposition from an electrolytic solution containing the metal nitrates. Although both of these methods produce precursors with the proper stoichiometric ratios, vast differences in other properties such as reactivity, density, thickness, and morphology exist. The effects of these precursor properties upon subsequent superconducting characteristics such as phase development, final morphology, and electrical transport are characterized by XRD), SEM/optical microscopies, R vs. T and J(c) measurements, respectively. Both types of precursors have produced superconducting films with high Jc's. Phase-pure textured films have been obtained on a variety of substrates. C1 SANDIA NATL LABS,ALBUQUERQUE,NM 87185.

First, a precursor powder with the stoichiometry Pb0.46Ba0.40Sr1.52Ca1.86Cu3.00Ox(Ag-0.37) (PBSCCO) was synthesized with the particle size of this powder being subsequently reduced to 4-6 mu m using a ball mill. Next, this powder was mixed with ethyl cellulose binder and sprayed with an airbrush using an N-2 carrier gas. Flexible polycrystalline Y2O3:ZrO2 (YSZ) as well as single-crystal MgO, SrTiO3, NdGaO3, and LaAlO3 substrates were mounted on a hot plate with typical growth temperatures of 80-100 degrees C. Growth times of similar to 10 min provided films which were 5-20 mu m in thickness. After an intermediate O-2 anneal to remove the organic binder, these films were subjected to a flowing 2-zone thallination process. Very well c-axis oriented Tl(0.70)Pb(0.36)Ba(0.39)Sr(1.58)Ca(1.98)Cu(3)0(x) (TP-1223) phase material was obtained for films grown on single-crystal LaAlO3. Films grown on all other substrates surveyed in the study gave rise to impurity phase formation and/or incomplete reaction. The PBSCCO and TP-1223 films were characterized by theta/2 theta and omega-rocking curve X-ray diffraction (XRD) analyses, scanning electron microscopy (SEM), variable temperature magnetic measurement, and inductively coupled plasma atomic emission spectroscopy (ICPAES).

An RTP cycle to approximate to 915 degrees C for 20 seconds in Ar produces massive melting of the superconducting powder but not the Ag substrate. Subsequent annealing under O, in sealed An foil with a Tl source yields' a brick-wall microstrocture consisting of c-axis aligned, plate-like grains. X-ray diffration and Meissner data show a mixture of the Tl-1223 and Tl-1212 phases while energy-dispersive spectroscopy identifies the plate-like grains its the desired Tl-1223. Magnetization data suggest intergramular supercurrents flowing across the entire film. Critical current densities inferred from hysteresis are 9x10(4) A/cm(2) at 5 K in low fields, decreasing by a factor of 5 in 5 tesla.

Highly textured yttria-stabilized-zirconia (YSZ) buffer layers were deposited by using ion beam assisted deposition (IBAD). Pulsed laser deposited YBCO films were not only c-axis oriented with respect to the film surface but also strongly in-plane textured. The in-plane mosaic spread of YBCO films was similar to 10 degrees. A critical current density of 8x10(5) A/cm(2) was obtained at 75 K and zero field for thin YBCO films. It was also demonstrated that thick YBCO films with a high critical current and excellent magnetic field dependence at liquid nitrogen temperature can be obtained on flexible nickel substrates by using the textured buffer layers.

The deposition technique employed a cathode comprised of a precursor alloy for the vacuum arc plasma source. The precursor alloy was prepared by multiple are-melting of mixed metallic constituents of the high-temperature superconducting material Bi2Sr2CaCu2O8+y (BSCCO-2212) and 50 wt.% of Ag. The presence of silver in the precursor alloy film was expected to allow accommodation of the lattice and thermal expansion mismatch between the oxidized film and the silver substrate. Following deposition, controlled oxidation of the precursor alloy thin film on the Ag substrate was performed to produce the superconducting composite on the silver substrate. After the heat treatment, the composite film consisted of single phase BSCCO-2212 highly c-axis oriented normal to the Ag substrate.

Conventional sintering is not sufficient to achieve strong links, but instead, melt processing is required to produce platelets which can develop into a textured structure. Changes in the stoichiometry of the precursor powders can lead to enhanced melt-phase formation at lower processing temperatures. An experimental matrix was designed with variations in the Tl/Pb ratio, the total Tl/Pb content, and the Ca/Cu level to change liquid formation and subsequent grain growth. Thirteen compositions were prepared in both pellet form and as Ag-clad tapes to investigate grain development over a range of thermal processing conditions. Tapes were produced using unreacted powders by the powder-in-tube method and processed by conventional furnace annealing. We report here on the transport properties of these tapes, their strong link behavior, and microstructural development. C1 INTERMAGNET GEN CORP,LATHAM,NY 12110.

The normal-metal included a gradient Pr-doped Y1-xPrxBa2Cu3O7-delta layer which was composed of a light doping (x=0.1) next to both YBa2Cu3O7-delta electrodes, a slightly higher doping (x=0.5) towards the center, and a doping concentration of x=0.5 in the middle of the N-layer. A gradient of the doping profile of the N-layer instead of an abrupt one provides good thermal, structural, and chemical compatibility between adjacent regions. The multilayer configuration of the gradient Pr-doped N-layers on YBa2Cu3O7-delta showed good growth structure as confirmed by X-ray diffraction and Rutherford backscattering channeling tests. The SNS junctions fabricated in such a way showed resistively shunted junction current vs voltage characteristics above 77 K. Microwave induced Shapiro steps above 77 K and voltage modulation of dc SQUIDs at 77 K were both demonstrated with this technology.

Since the photons initially excite individual electrons to HBAR omega much greater than k(B)T, however, direct relaxation of these hot electrons to phonons must also be considered, Theoretical estimates suggest that this extra relaxation channel increases the effective thermal conductance for HBAR omega much greater than k(B)T and influences bolometer noise, Calculations of these effects are presented which predict very useful performance both for ground-based and space-based astronomical photometry at millimeter and submillimeter wavelengths.

For both types of junctions we observe resistively shunted junction current-voltage characteristics. The critical currents I-c in all cases are similar for a given ratio of YBCO thickness-to-step height, while the normal resistance R(n) for the Au deposited at 600 degrees C is consistently 25% lower than for the Au deposited at 100 degrees C. The normalized temperature dependence of the I(c)R(n) product is nearly identical for all junctions with Au deposited at high temperatures but varies among junctions on a single chip for Au deposited at 100 degrees C. Low magnetic field modulation of the critical current can show either the expected Fraunhofer-like pattern or a double-junction modulation for both types of devices. The modulation period is consistently a factor of 3 lower for the high-temperature deposited Au. C1 NIST,DIV ELECTROMAGNET TECHNOL,BOULDER,CO. CONDUCTUS INC,SUNNYVALE,CA 94086.

The proposed supervisory control system is a reconfigurable hybrid architecture structured into three functional levels of hierarchy, namely, execution, supervision, and coordination. While the bottom execution level is constituted by either reconfigurable continuously varying or discrete-event systems, the top two levels are necessarily governed by reconfigurable sets of discrete-event decision and control systems. Based on the process status, the set of active control and supervisory algorithm is chosen. The underlying concept of the proposed reconfigurable hybrid decision and control is described along with its implementation on the feedwater system at the Experimental Breeder Reactor II of the Argonne National Laboratory. The performance of the hybrid system to accommodate component failures is then evaluated in an in-plant experiment. C1 PENN STATE UNIV,DEPT MECH ENGN,UNIVERSITY PK,PA 16802.

The principal features of the electron source are the high current density and high field without the onset of vacuum arcs or are collapse prior to gap closure. The electron beam diode was controlled by a variable pulse-width output Marx generator. Fields to 600 kV/cm were applied for 25 to 30 ns, and to 300 kV/cm during space-charge limited current conduction at pulse lengths of 100 to 120 ns. Evidence of the transition to space-charge limited unipolar flow and transition to bipolar space-charge limited flow was obtained. Traces of the typical behavior and the different transitions are shown. Beam uniformity was measured by using a set of Faraday cups. The Faraday cup setup was then used to demonstrate suppression of electron emission from surfaces coated with a dielectric film. C1 TETRA TECH INC,ALBUQUERQUE,NM. LOS ALAMOS NATL LAB,LOS ALAMOS,NM.

The device is designed for use as a plasma source for molecular gas lasers operating in the UV and visible spectra, The cathode consists of 1 mm thick nickel disks and 0.1 mm tungsten foil disk segments stacked alternately, forming a cylindrical geometry on its outer surface and a near-spherical geometry inside, The tungsten foil disk inner diameters vary along the longitudinal axis of the cathode, With this special geometric arrangement one hollow cathode structure is embedded within another. The spacing between the segments (tungsten foil disks) creates one hollow cathode geometry, and the spherical geometry formed by the inner diameter of the segments is a second hollow cavity, This design permits one to operate the device at an expanded pressure range, The device's voltage and current characteristics are studied at different operating pressures and the optimum operating parameters such as pressure, voltage, current, and foil thickness are investigated, Helium, argon or a helium-argon mixture is used as the fill gas throughout the series of experiments.

The mean-free-path for ionization of cathode material sputtered in the low-current hollow-cathode phase can be shorter than the cathode-anode gap distance, and ionized atoms can return to the cathode surface, self-sputtering with a yield greater than one. The self-sputtered cathode atoms become ionized in the beam of electrons accelerated in the cathode sheath. A large fraction of the discharge current at the cathode surface can be carried uniformly over the surface by ions, and a very high electron emission density is not required to maintain the high current.

The sheath collapse is found to be important for high repetition rate pulses. Good correlation is shown between the model and experiment for a wide variety of voltage pulses and plasma conditions.

The method is based on a novel ''propagator'' technique. The calculation of propagators to allow for various effects such as variable mean free path and anisotropic scattering is demonstrated. The role of the plasma in determining the neutral species behavior is investigated in some detail. The transport to the walls and the recycling of ions and hot neutrals are examined and shown to strongly affect the chemistry. The effects of truncating the hot tail of the electron distribution function and altering the spatial distribution of hot electrons are also calculated, and are shown for the most part to be relatively small provided the power deposition is held constant. The values of sticking coefficients for neutral radicals are shown to have a significant effect. The model results match experimental trends for CF4 and CF3 densities as functions of power, pressure and inlet dow rate variation. C1 UNIV WISCONSIN,ENGN RES CTR PLASMA AIDED MFG,MADISON,WI 53706.

This paper presents an optimization model that identifies the types of component improvements and the level of effort spent on those improvements to maximize one or more performance measures (eg, system reliability or availability) subject to constraints (eg, cost) in the presence of uncertainty about the component failure rates. For each component failure mode, some possible improvements are identified along with their cost and the resulting improvement in failure rates for that failure mode. The objective function is defined as a stochastic function of the performance measure of interest - in this case, 5(th) percentile of the mean time between-failure distribution. The problem formulation is combinatorial and stochastic. Genetic algorithms are used as the solution method. Our approach is demonstrated on a case study of a personal computer system. Results and comparison with enumeration of the configuration space show that genetic algorithms perform very favorably in the face of noise in the output: they are able to find the optimum over a complicated, high dimensional, nonlinear space in a tiny fraction of the time required for enumeration. The integration of genetic algorithm optimization capabilities with reliability analysis can provide a robust, powerful design-for-reliability tool.

The ion exchange material was a hydrous sodium crystalline silicotitanate, labeled TAM-5, which is being developed by Texas A&M University, Sandia National Laboratories, and UOP Associates. Cesium distribution coefficients collected by Pray et al. on a NCAW simulated waste solution were predicted with deviations of less than 25% for solutions containing 1 M, 3 M, and 5 M Na+ and Na:Cs ratios of 10(3)-10(8). The deviations were less than 5% for the solutions with 1 M Na+. Cesium distribution coefficients were also predicted and compared with values measured by Egan et al. for TAM-5 and for a storage tank supernate and a ''newly generated'' waste solution. Excellent results were obtained for the ''newly generated'' waste simulated solution, which did not contain potassium or rubidium. The predictions for the other simulated waste solution were significantly greater than the measured values, because of the presence of large concentrations of potassium or rubidium. The effect of competitive ion exchange between Os, Rb, and K was not included in the theory. However, the effect of competitive exchange of Cs, Rb, and K appears to be greater for the Oak Ridge simulated waste solution than for the NCAW waste.

BHN 91) fruit were hand harvested at the pink stage of maturity and stored red-ripe at 12.5, 20, and 30 degrees C in air, 3% O-2 + 5% CO2, and 0.5% O-2 + 20% CO2 for up to 16 days. Half the fruit were inoculated with Fusarium solani. Control fruit retained the best appearance in 3% O-2 + 5% CO2 at both 20 and 30 degrees C. Inoculated fruit at 12.5, 20 and 30 degrees C in air or 3% O-2 + 5% CO2 remained acceptable for approximately 12, 3, and 2 days, respectively, but deteriorated more rapidly than those in 0.5% O-2 + 20% CO2 as temperature and time increased. Off-odours were present in all 0.5% O-2 + 5% CO2 treatments by days 12, 9, and 5 at 12.5, 20, and 30 degrees C, respectively. Subjective evaluations tended to remain higher for 0.5% O-2 + 20% CO2 even though internal firmness and physical integrity were inferior, and symptoms of anaerobiosis were presumed. A significant time- and temperature-dependent increase in pH of locular and pericarp tissue and supernatant pH occurred in inoculated regions of fruit held in air by day 12, 6 and 3 at 12.5, 20, and 30 degrees C, respectively. In contrast, reduced acidity occurred at 9 and 5 days in 3% O-2 + 5% CO2 at 20 and 30 degrees C, respectively. Generally, increased pH followed a trend with air > 3% O-2 + 5% CO2 > 0.5% O-2 + 20% CO2. Titratable acidity in control fruit declined regardless of atmosphere when held at 12.5 degrees C. Initial locule and supernatant pH was sufficiently low to be considered safe, but the pericarp pH of 4.63 approached the food safety threshold, and exceeded 4.7 with storage. Subsequently, food service establishments should beware of potential contamination when holding ripe fruit due to possible decay and metabiosis, anaerobiosis occurring in dressings, and decreased acidity with ripening.

There are also probabilistic models of underlying terrain types from a tactical perspective that provide evidence supporting or denying the presence of forces at a location. The system compares sets of detected military vehicles extracted from imagery against the models of military units and their formations to create evidence of force type and location. Based on this evidence, the system dynamically forms hypotheses of the presence, location and formations of military forces on the ground, which it represents in a dynamically modified Bayesian network. The IES/BTI functional design is based on a decision theoretic model in which processing choices are determined as a utility function of the current state of interpretation of imagery and a top-level goal to exploit imagery as accurately and rapidly as possible, given the available data, current state of the interpretation of force hypotheses and the system processing suite.

Several subclones from this population were studied for their survival and mutation responses and then one was chosen for further characterization based on this data. The studies carried out on this subclone, designated N806, show that its spontaneous HPRT mutation rate is approximately 10 times higher than that of wild-type V79 cells and it is almost three times more mutable than the wild-type cells when both are induced by UVB or UVC. The mutation responses of N806 and MI2G cells to 50-kVp X-rays are different, but the N806 cells do not appear to be hypermutable as they are with UV. N806 cells are also moderately more resistant to the cytotoxic effects of UV radiation but are more sensitive than MI2G cells when exposed to X-rays. Assays to measure the removal of cyclobutane pyrimidine dimers (CPDs) and the incision step of nucleotide exciscion repair have revealed no detectable difference in the repair capacities of N806 and parental V79 cells. These results suggest that chronic, protracted UV irradiation may be able to induce a 'mutator phenotype' in a subpopulation of the progenitor cells.

The constitutive model is developed within the general Framework of continuum thermodynamics for irreversible processes by identifying a proper set of internal variables together with their associated generalized forces. Three major anisotropies are considered, including anisotropic elasticity, anisotropic plasticity and anisotropic damage. The physical implications, mathematical restrictions, and numerical implementations, as well as practical applications are discussed in some detail. Attention is focused on the development of a new damage characteristic tenser which is based on the hypothesis of damage energy equivalence and provides a good physical representation of damage evolution. An approach is also presented to account for microcrack opening and closing. A viscoplastic regularization algorithm is proposed to take into account the strain rate effect and to improve numerical stability. The numerical implementation is described in detail. In particular, a new and simple two-step operator split algorithm (elastic predictor and coupled plastic-damage corrector) with subincrements is developed which can efficiently integrate fully coupled elastoplastic damage constitutive relations. Numerical results are presented for sheet forming processes. Good agreement with some theoretical and experimental results is also obtained. C1 UNIV LIEGE,DEPT MSM,B-4000 LIEGE,BELGIUM.

Although PVM has become an important infrastructure for parallel programmers, we continue to develop the system based both on user feedback and our own research interests. In this paper we present new communications routines and briefly characterize their performance. We describe new extensible services that allow advanced users to customize certain aspects of the default PVM functionality. An overview of shared-memory PVM optimizations is presented. PVM's new tracing facility and a graphical console that utilizes this capability are described. Finally, we discuss future extensions to PVM now under investigation.

Blenheim) was sown on two dates (March and April) and given 100 kg N/ha in three different proportions, 100%, 67% and 33% at sowing time and the remainder as a top-dressing at an early tillering stage, growth stage (g.s.) 21-22, on three different soils over a 3-year period (1989-91). The early-sown barley (March) gave significantly greater grain yields in seven experiments, lower grain nitrogen in eight experiments and lower screenings in all nine experiments. Applying all the N at sowing consistently produced the best quality grain. The greater the proportion of N applied at sowing time the lower the grain nitrogen and the lower the screenings for both sowing dates. Timing of N application generally did not affect grain yield when the barley was sown in April but it gave variable results with the early-sown barley. Over the 3-year period timing of N application did not give a significant difference in mean yield for either of the sowing dates on the heavier textured soils. On the light gravelly soil, applying all the N at sowing time significantly reduced yield on the March-sown crop in 1 of the 3 years.

In all years, fluazinam gave good control of foliage blight, significantly delaying the onset of disease and the level of foliage blight at the end of the season compared with the untreated control. Compared with mancozeb, fluazinam significantly delayed onset in 4 of the 5 years while the level of foliage blight at the end of the season was significantly reduced in 1989 and 1990. Fluazinam did not significantly delay the onset of disease or reduce the level of foliage blight at the end of the season when compared with a pre-pack phenylamide + mancozeb programme (first three sprays) followed by mancozeb alone. Fluazinam was as effective as mancozeb in controlling tuber blight in 4 of the 5 years and was significantly better than mancozeb in 1992. No significant differences in tuber blight control could be found between fluazinam and the phenylamide programme. The relative effects of fluazinam, mancozeb and the phenylamide-based programme on total and marketable yields were inconsistent and varied between years. Phenylamide-resistant inoculum was present in the trial area in all 5 years of the experiments. RP DOWLEY, LJ (reprint author), TEAGASC,OAK PK RES CTR,CARLOW,IRELAND.

Blenheim) was sown on three sowing dates (March, early April, late April) at three rates of N (100, 125 and 150 kg/ha) on three different soil types (light, medium and heavy) in the south-east of Ireland in 1990 and 1991, to test the effect of these factors on yield and quality. The earliest-sown spring barley generally gave the greatest yield and the best quality grain (lowest grain nitrogen and smallest amount of screenings). Increasing increments of N always reduced the quality of the grain but did not always increase the grain yield. The higher rates of N (125 and 150 kg/ha) increased yields on the light soil in 1991 and on the medium soil in 1990 and 1991. There was no response on the heavy soil.

The hydrogenated material was used as intrinsic layers of n-i-p diodes, which showed interesting electrical characteristics. From time of flight (TOF) measurement for our best samples produced at hydrogen to silane ratio of 15, we obtained mobility (mu) values about 3-4 times larger than our standard amorphous silicon(a-Si:H). Approximately a factor of 2 improvement was observed for mu tau values. The N-D* values of the hydrogen diluted a-Si:H were measured for the first time and show lower ionized dangling bond density than the normal a-Si:H material. At a hydrogen to silane gas flow ratio of 20, some microcrystalline formation was observed in the deposited material. We propose a simple macroscopic model to assess the effect of microcrystals and grain boundaries on the electronic properties of mixed amorphous and microcrystalline material.

These superconductors were subjected to a high temperature annealing process. After annealing, the critical current densities (J(c)) of both as-melt and deformed superconductors are found to have decreased dramatically both in zero held as well as in an applied field of 1.5 T. Furthermore, the distinct characteristic of deformed superconductors, i.e., J,IH parallel to c-axis) approximate to J(c) (Hlia-b), has totally disappeared after annealing the samples at 9000C for 48 h in flowing oxygen. Transmission electron microscopy revealed that the high dislocation density normally observed in deformed 123 superconductors has been significantly reduced. In addition, several other microstructural changes were also investigated. These results indicate that the large amount of dislocations generated during the deformation process are elf ective 8ux pinning centers in thes e superconductors. Meanwhile, it is suggested that pinning by stacking faults is magnetically sensitive where the effect is maximum at low fields. C1 UNIV HOUSTON,TEXAS CTR SUPERCONDUCT,HOUSTON,TX 77204.

The two generalized phase diagrams are examined for their similarities and differences. The application of systematics in lanthanide compound series has been useful in predicting crystal structures (phase relationships), melting points, and enthalpies and free energies of formation. Analyses of these data indicate that there is 4f hybridization with the other valence and/or bonding electrons. It is most likely that the 4f hybridization involves the empty 4f level(s) just above the Fermi surface and not the filled localized 4f levels. Systematics has also been applied to the actinide metals. Since the experimental data are primarily limited to Th, U and Pu, and since the Valence changes from 3 to 7 in the early actinides, the usefulness of these techniques, which have been so successful for the lanthanides, has been limited. If more experimental data were available for actinium and its alloy systems, much more progress could be made in our understanding of actinide alloys and compounds. In addition, as a result of applying systematics, it is thought that the lattice parameters reported for Ac and AcH2 are quite likely to be wrong. It is proposed that the correct lattice parameter for f.c.c. Ac metal is 5.670 Angstrom, about 6.7% larger than the value which has been accepted up to now.

These lanact trihalides are the ones most readily prepared, and they exhibit the four different crystal structures known for all lanact trihalides (except trifluorides) at room temperature and pressure (RTP). Formula volumes are correlated with the RTP crystal structures. Correlations with cation radius and/or cationic/anionic radius ratio are used to systematize the structural relationships, including those encountered through the application of pressure. Finally, some unknowns to be addressed in future research are proposed. C1 OAK RIDGE NATL LAB,DIV CHEM & ANALYT SCI,TRANSURANIUM RES LAB,OAK RIDGE,TN 37831.

Therefore, comparing systematically selected properties of these materials can often provide insight into their electronic structures. The actinide series displays more complex electronic structures than does the lanthanide series; this is reflected in the more complex and variable properties exhibited by the actinides. A limited comparison of the two f-electron series of elements can be made by comparing the behaviors of their metals and oxides. The most notable differences in electronic and material behaviors are found with the metallic state, while with the oxides of these elements, perhaps the most studied compounds, the electronic structures and properties are more consistent. The objective here is to establish trends and differences in selected physicochemical properties of these two materials for each series, which may reflect differences in electronic structures. In this exercise, plutonium appears to occupy a pivotal position in the actinide series with reference to such properties; there does not seem to be a complete counterpart to it in the lanthanide series.

To this end optical and magnetic analyses of similar compounds are compared. In most cases this entails comparing trivalent actinide with trivalent lanthanide compounds although the f(1) configuration (Ce3+ diluted in Cs2NaYCl6 and Pa4+ diluted in Cs2ZrCl6) is treated in detail. In general the ground electronic states for lanthanide and actinide compounds with the same number n of f electrons (f(n)) and the same coordination about the metal ions are similar, although the total crystal field splitting in the actinides is approximately twice as great as for the lanthanides. The half-filled shell f(7) is a special case with a relatively large ground state splitting in the 5f(7) ground term caused by the effects of the much larger spin-orbit coupling.

This plane-parallel BRDF appears qualitatively similar to the empirically derived angular dependence models from the Earth Radiation Budget Experiment. But when these two different BRDFs are used to estimate net shortwave flux at the ocean surface, discrepancies of 20-60 W m(-2) can occur between the respective net surface nux estimations. When using either BRDF with Advanced Very High Resolution Radiometer data for surface radiation budget estimation, this uncertainty can be minimized by restricting the satellite viewing( polar) angle to between 30 degrees and 50 degrees. Accurate measurements of the planetary BRDF would help resolve these differences. C1 LOS ALAMOS NATL LAB,LOS ALAMOS,NM.

The dependence of the outflow from Coal Creek Canyon on surface cooling and channeling by winds above the canyon is explored by using three years of data from a portion of the network. The depth of the drainage flow and the height of the wind speed maximum were found to be largest at external wind speeds near 3 m s(-1). For lighter winds aloft, the drainage depth, the height of the jet, and the drainage wind speed depend both on external wind speed and on the strength of the surface cooling. The magnitude of the near-surface temperature differences was also found to decrease with increasing surface cooling, possibly because of increasing turbulence caused by winds interacting with surface topography.

It has been shown that the introduction of transition metal cations into ZSM-5 zeolite, either as charge balancing cations (Co2+, Nb5+) or as lattice cation (V5+), enhances the activity and selectivity of the catalysts for the oxydehydrogenation of ethane. The O-18(2) temperature-programmed isotope exchange technique was used to probe the likely active sites on the catalysts. It was demonstrated that the introduction of transition metal cations results in the formation of active sites responsible for the formation of single-step double exchange between gas phase oxygen and lattice oxygen. The activity for formation of single-step double exchange O-16(2) is a good indicator for the activity for oxydehydrogenation of ethane to form ethylene. The introduction of transition metal cations (Cu2+, Co2+, etc.) into ZSM-5 zeolite lowers the temperature required for isotope exchange between gas phase oxygen and lattice oxygen. The temperature required for isotope exchange depends on the cations introduced. The activity for facilitating single-step double exchange between gas phase O-18(2) and lattice oxygen (O-16) and the activity for oxydehydrogenation of ethane to ethylene decrease in the same order: Co-H-ZSM-5 > Cu-Na-ZSM-5 > [V]-ZSM-5 > Nb-ZSM-5 > Na-ZSM-5 similar to H-ZSM-5 similar to Cu-ZSM-5. It appears that the structural defects created by introducing transition metal cations are responsible for the enhanced activity and selectivity for the oxydehydrogenation of ethane. NH3-TPD results show that the presence of strong Bronsted acid sites are undesired for oxydehydrogenation reactions. However, the presence of relatively weaker acid sites is not harmful for the reaction. (C) 1995 Academic Press, Inc. C1 UNIV CALIF BERKELEY,LAWRENCE BERKELEY LAB,DIV MAT SCI,BERKELEY,CA 94720.

Drying in air at 110 degrees C or under vacuum at 100 degrees C and then calcining in air at 400 degrees C causes large Co3O4 particles to form, which easily reduce under hydrogen at 300 degrees C. In contrast, dried samples annealed under UHV prior to calcining exhibit dramatically different characteristics. The decomposition of cobalt nitrate during drying initiates the formation of a surface cobalt silicate. Prolonged air drying eventually converts the surface silicate into Co3O4, while vacuum drying disperses the nitrate precursor on the support, forming cobalt silicate islands. Annealing air-dried samples in UHV stabilizes the surface silicate against reduction or oxidation through the migration of Co2+ ions into the support to form a well-ordered bulk cobalt silicate. Annealing of vacuum-dried samples to 200 degrees C in UHV produces a continuous, conductive surface silicate that sinters upon heating to temperatures above 250 degrees C. Analysis of species generated during the decomposition of the Co(NO3)(2) . 6H(2)O precursor indicates that the concentration of gas phase NOx near the surface determines the nature of the cobalt surface phase. The formation of an intermediate surface cobalt silicate under specific activation conditions maximizes the amount of reducible cobalt surface area available for FT reactions.

The particles are predominantly single nanocrystals with diameters in the order of 2.0 to 2.5 nm. Occasionally, twinned particles are also observed. All investigated particles represent solid solutions of Pt and Ru with compositions very close to the nominal one. Based on two-dimensional projection in high resolution images, it is suggested that the well-resolved particles are of cubooctahedral shape. In addition to {200} and {111} facets, {113} facets are also observed. (C) 1995 Academic Press, Inc. C1 UNIV CALIF BERKELEY,LAWRENCE BERKELEY LAB,DIV MAT SCI,BERKELEY,CA 94720.

CRITICAL-EVALUATION OF THE THERMODYNAMIC PROPERTIES OF SOLID AND GASEOUS GERMANIUM(II) SULFIDE GES AND GERMANIUM(IV) DISULFIDE GES2, AND DIGERMANIUM DISULFIDE GE2S2(G) - ENTHALPIES OF DISSOCIATION OF BONDS IN GES(G), GES2(G), AND GE2S2(G) SO JOURNAL OF CHEMICAL THERMODYNAMICS LA English DT Article ID INFRARED-SPECTRA; HARTREE-FOCK; ENERGIES; CHALCOGENIDES; CONSTANTS; SE; IR AB This is a critical evaluation of the thermodynamic properties of the known solid and gaseous compounds of(germanium + sulfur): GeS(cr), GeS(g), GeS2(cr), GeS2(g), and Ge2S2(g). The heat capacity of GeS(cr) at low and moderate temperatures was evaluated from all the information available in the literature, and the properties: C-p,m(o)(T), {H-m(o)(T)-H-m(o)(T')}, S-m(o)(T), and Phi(m)(o)(T) = (Delta(o)(T)S(m)(o) - Delta(T)(T)H(m)(o)/T), where T' = 298.15 K, were computed to T = 930 K, close to the melting temperature, above which decomposition to a (germanium + sulfur) eutectic and uncombined germanium is believed to occur. On the basis of our recent Value for Delta(r)(H)(m)(o)(GeS, cr, 298.15 K) (J. Chem. Thermodynamics 1994, 26, 727), Delta(r)H(m)(o)(T) and Delta(f)G(m)(o)(T) were also calculated over the same temperature range. A critical assessment of the enthalpy of sublimation Delta(sub)H(m)(o) yielded Delta(r)H(m)(o)(GeS, g, T). In another part of the present series (J. Chem. Thermodynamics 1995, 27, 99), we determined Delta(r)H(m)(o)(GeS2, cr, 298.15 K); the corresponding Delta(r)H(m)(o)(GeS2, cr, T) is tabulated in the present paper to T = 1000 K. Ab initio molecular-orbital calculations showed the cyclic (C-2v) arrangement to be the most stable for Ge2S2(g), and the predicted structure and vibrational wavenumbers were used in calculations of its thermodynamic properties as a function of temperature by means of statistical mechanics. A similar treatment of the linear GeS2(g) is described. The assessed Delta(r)H(m)(o)(GeS, g, T --> O) is in harmony with our reinterpreted molar enthalpy of dissociation D-m(o)(GeS) from spectroscopy; and the enthalpies of dissociation of the bonds in GeS2(g) and Ge2S2(g) are also discussed. In summary, the molar enthalpy of dissociation of the (triple) bond in GeS, 535 kJ . mol(-1), is the largest for any Ge-to-S linkage, and the mean molar enthalpy of dissociation of the (double) bonds in GeS2, 404 kJ . mol(-1), is greater by 110 kJ . mol(-1) than [D-m(o)(Ge2S2)] because, presumably, Ge2S2(g) has essentially single Ge-S bonds only. The molar enthalpy of dissociation of the ''primary'' bond D-m(o)(S-GeS) is of comparable magnitude to the mean molar dissociation enthalpy of the Ge-S bonds in Ge2S2(g).

When the multipole expansions are carried out to octapoles, the root mean square (rms) error in the potential is always less than that from PDCs. Electrostatic interactions in pairs of these nucleic acid bases were also evaluated using ACMEs up to octapoles and PDCs. The electrostatic interaction energies from ACMEs were found always to be larger than those from PDCs or the total self-consistent field (SCF) interaction energy. The value of the electrostatic energy differs by as much as approximately 19 or as little as approximately 8 kJ/mol between the ACME and PDC methods. The rank ordering provided by the electrostatic models is grossly similar but differs in the ranking of systems with two and three hydrogen bonds. A rigid twist about the N-H ... N axis of the pairs was examined using SCF calculations and the electrostatic models. It was found that with ACMEs the energy required for a 90-degree rotation was always higher than that found from SCF calculations. With PDCs, similar results are obtained, except with the adenine/thymine and 9-methyl-adenine/1-methyl-thymine pairs. In these instances, the barrier is about 4 kJ/mol lower than that found with SCF calculations. These results demonstrate that integration of the charge density can provide convergent multipole expansions that provide a more accurate description of the electrostatic potential than the commonly used PDC model. In addition, the description of electrostatic interactions during twisting of AT and mAmT given by this model is shown to be somewhat anomalous. (C) 1995 by John Wiley & Sons, Inc.

These methods, which allow the use of general non-orthogonal mixed-polyhedral unstructured grids, are direct generalizations of the canonical stag gered-grid finite difference method. These methods are conservative in that they locally preserve ''divergence'' or charge, Employing mixed polyhedral cells (hexahedral, tetrahedral, etc.), these methods allow more accurate modeling of non-rectangular structures and objects because the traditional ''stair-stepped'' boundary approximations associated with the orthogonal grid based finite difference methods can be avoided. Numerical results demonstrating the accuracy of these new methods are presented. (C) 1995 Academic Press, Inc. C1 NASA,AMES RES CTR,ADV COMP SCI RES INST,MOFFETT FIELD,CA 94035.

A. Bird, proves to be extremely efficient for simulating dilute gas flows. However, due to the relatively large transport coefficients at low densities, a high Rayleigh or Reynolds number is difficult to achieve by this technique. We present a modified version of DSMC in which the relaxation processes are enhanced and the transport coefficients reduced, This is achieved by increasing the ratio between collisions and free flow of particles in a suitable way. The modified algorithm is mostly useful for statistical physics applications, since it leads to the correct fluctuation spectrum. Several computational experiments are described; they demonstrate that the correct equilibrium and nonequilibrium fluid properties are preserved. The new algorithm is shown to be significantly more efficient than molecular dynamics for simulating complex hydrodynamical flows. (C) 1995 Academic Press. Inc.

A new gauge is defined that reduces the coupling between the equations for the nonzero components of the vector potential. The GL equations are written in a symmetric form by means of continuous link variables. A second-order accurate scheme is used for the numerical approximation. Numerical experiments demonstrate that the discrete GL model leads to asymmetric solutions in the plane; symmetry is recovered only in the limit as the mesh size goes to zero. Results of computational experiments to find the upper critical field and an empirical power law for Vortex interactions are given. (C) 1995 Academic Press, Inc.

The material was characterized by photoluminescence (PL), x-ray reflectivity, and electrical measurements on resonant tunneling diodes (RTDs). High quality material was demonstrated throughout the pressure range, but a weaker PL intensity at higher pressure (220 Torr) indicates lower lifetimes. Interface abruptness was degraded at higher pressures due to gas transients. This was confirmed by x-ray reflectivity measurements and the performance of RTDs. We have established a low pressure limit to interface roughness of 0.2-0.5 nm, determined by x-ray reflectivity. C1 PRINCETON UNIV,DEPT ELECT ENGN,PRINCETON,NJ 08544.

Lift-off was accomplished by taking advantage of the high etching selectivity between AlSb and InAs in an aqueous hydrofluoric acid etching solution, allowing a thin layer of AlSb to serve a sacrificial layer to facilitate the Lift-off of the InAs. The InAs layers were transferred with little measurable effect on the electrical and structural properties of the films, as evidenced by Hall effect and x-ray measurements. The technique can easily be extended to transfer more-complex GaSb/AZSb/InAs structures. C1 IOWA STATE UNIV SCI & TECHNOL,DEPT ELECT & COMP ENGN,AMES,IA 50011.

One example of this situation is aircraft fuel systems, where the pump inlet may have two-phase mixture due to the desorption of the dissolved gases at low pressures at higher altitudes. A simple procedure of selecting proper design conditions for the inlet inducer and a method of sizing the inducer, impeller and volute to meet all the design requirements has been described. This procedure has also been applied to a typical fighter plane boost pump design. RP ROHATGI, US (reprint author), BROOKHAVEN NATL LAB,DEPT ADV TECHNOL,BLDG 475B,UPTON,NY 11973, USA.

Failure to prepare AgFOsF6 (AgOs-F-6 + F-2 --> AgF2 + OsF6) indicates that the one-dimensional chain cation (AgF)(n)(n+) takes the electron from OsF6-. The Ag-(solv)(2+) ion oxidizes IrF6- to IrF6 and at -78 degrees C in AHF, O-2 to O-2(+) (O-2 + Ag2+ + 2AsF(6)(-) --> O2+AsF6- + AgAsF6). This reaction is negligible at similar to 20 degrees C because of the loss of translational entropy that accompanies the formation of the crystalline products. Dissolution of AgF3 in AHF with A (A=AsF5, SbF5 or BiF5) gives a solution {Ag-(solv)(III)} which oxidizes PtF6- or RuF6- to MF(6) and O-2 to O-2(+). K2NiF6 in AHF below -60 degrees C with greater than threefold molar excess of BF3 yields yellow-brown solutions {Ni-(solv)(IV)} which also oxidize PtF6- or RuF6- to MF(6). The species Ag-(solv)(III) and Ni-(solv)(III) in AHF are oxidizers of unsurpassed power. C1 UNIV CALIF BERKELEY,LAWRENCE BERKELEY LAB,DIV CHEM SCI,BERKELEY,CA 94720.

Using an ad hoc monotonically increasing thermal profile, Green's function is derived. It is shown that apart from the usual acoustic and acoustic-gravity branches, waves guided by the atmospheric thermocline are also excited. The leading term of an asymptotic expansion of Green's function is then used to obtain an analytic expression of the acoustic front and the impulse tail.

These methods are based upon thermal desorption into an ion trap mass spectrometer. Selective detection of the target compounds is achieved by isobutane chemical ionization in combination with collision-induced dissociation, which yields characteristic fragment ions. Rapid sample clean-up steps were also devised to reduce interferences from the sample matrix. The low detection limits achieved with this method suggest that it may be possible to take small tissue samples from livestock by needle biopsy, without requiring animal sacrifice for the analysis. In addition, because the new methods may be performed more quickly than conventional methods requiring substantial sample preparation and analysis time, more samples could be analyzed.

When offered a choice between stimulus groups composed of familiar siblings and unfamiliar nonsiblings (both stimulus groups, as well as test individuals, raised on the same diet), larvae did not associate preferentially with either stimulus group. In diet-based cue experiments, larvae raised on Tubifex worms associated preferentially with unfamiliar nonsiblings raised on the same diet over unfamiliar siblings raised on rabbit chow. In the complementary experiment, however, larvae raised on rabbit chow did not associate preferentially with either stimulus group. These results do not support a role for kin discrimination and kin selection in S. intermontanus larvae. If discrimination does occur, the results suggest that environmentally derived cues may be the predominant means by which kin are discriminated. Moreover, the different results of the diet-based cue experiments suggest that larvae are not restricted to prefer only cues representative of their natal environment. Although familiarity is involved, larvae also may be capable of reacting preferentially to a novel stimulus based on some type of quality assessment.

Laser desorption provides a soft ionization technique for these non-volatile compounds and generates characteristic positive and negative ions. The positive-ion spectra usually consist of [M + Na](+) and [M + K](+) ions, whereas the negative-ion spectra reveal [M - H](-) ions and fragment ions. Collision-induced dissociation experiments were used to probe tbe fragmentation pathways of these negative ions. The fragmentation observed for negative ions supports known resonance structures and provides detailed structural information which can be used to differentiate isomers, such as L- sepiapterin, L-biopterin, and L-primapterin (sometimes referred to as 7-biopterin). However, optical isomers, such as monapterin and neopterin, cannot be resolved by differences in fragmentation alone, Twenty-three compounds that are pterins or related structures were characterized.

Two coating thicknesses of 0.1 and 1.0 mm were used in the study. The average strength and Weibull coefficients of the intermetallic samples coated with the 0.1 mm Al2O3 coating were very similar to those of the uncoated intermetallic samples. On the other hand, the average strength of the samples coated with 1.0 mm Al2O3 was significantly lower than the strength of the uncoated intermetallic substrate. The lower strength of the 1.0 mm coated samples was attributed to the higher volume fraction of the Al2O3 coating (which has a lower strength than the Ti-25Al-10Nb-3V-1Mo substrate) and higher porosity in the 1.0 mm coating. The Young's modulus and damping values of the 0.1 mm Al2O3-coated intermetallics did not vary significantly from those of the uncoated substrate. However, the damping values of the 1.0 mm Al2O3-coated intermetallics were significantly larger than those of the uncoated substrate. The higher damping values measured for the 1.0 mm Al2O3-coated samples were attributed to the higher porosity in the thicker coating and to defects in the coating as a result of the spraying process.

Experimental results have shown that a stagnant atmosphere containing volatiles evolved during debinding can cause slumping of the green samples. Removal of volatiles from the sample zone aids debinding and can reduce cycle times and improve sample quality. Residual carbon and oxygen can be controlled during debinding by adjusting the atmosphere composition. This paper presents the results of PIM 70 vol% spherical copper powder and 30 vol% binder. Debinding atmospheres were altered to determine the effect of debinding on the green body and the sintered sample.

The microstructure of the deposited films was characterized by x-ray diffraction (XRD) and high resolution transmission electron microscopy (HRTEM). At the growth conditions studied, films were single-phase rutile and epitaxial, but showed variant structures. Three distinct in-plane epitaxial relationships were observed between the films and the substrate. A crystallographic model is proposed to explain the film morphology. This model can successfully predict the ratio of the width to the length of an averaged grain size based upon the lattice mismatch of the film-substrate interface.

The resistors fabricated in such a way were highly stable under power loading or thermal cycling. Resistors with one digit temperature coefficient of resistance (TCR) could be easily controlled by the layer thickness ratio of the tantalum nitride to the ruthenium oxide and the ex situ annealing temperature or duration. Auger electron spectroscopy depth profile on the thin films indicates that the ruthenium oxide layer is well defined for the as-deposited form. Nevertheless, interdiffusion takes place after thermal treatment of the bilayer which is used to tune the temperature coefficient of resistance and to stabilize the resistance of the resistors.

The combination of these functional and structural methods successfully distinguished communities from disparate origins. Multivariate analysis of the data showed good agreement between the results of the two methods. Subsurface communities tended to respire amino acids over carbohydrates and demonstrated preferential use of individual compounds such as acetate and Tween as sole carbon sources. PLFA profiles indicated that the groundwaters predominately contained gram negative aerobic heterotrophic populations, the drilling muds and cuttings were populated by gram negative anaerobes and the core communities were composed of anaerobic gram negative bacteria and gram positive bacteria. The utility of this approach as a component of quality assurance of core samples obtained for microbiological analysis during mud rotary coring was demonstrated. Monitoring of controlled bioprocesses, environmental remediation and detection of environmental disturbance are some of the numerous potential applications for these community-level characterization methods. Since combined analyses such as these can simultaneously provide specific information about individual community members and about community-level function, it is hoped that these methods will prove useful in answering fundamental questions in microbial ecology, such as the relationship between in situ community structure and its measurable function.

It is intended to give an intuitive appreciation for the various factors that influence the magnitude of the secondary fluorescence correction, the specimen geometry in particular, and to serve as a starting point for the derivation of quantitative correction formulae. This formulation is primarily intended for the X-ray microanalysis of electron-transparent specimens in the analytical electron microscope (AEM). The fluoresced intensity, l(x)(y) is expressed relative to the primary intensity of the fluorescing element, I-y, rather than to that of the fluoresced element, I-x, as has been customary for microanalysis. The importance of this choice of I-y as a reference intensity for the electron-transparent specimens examined in the AEM is discussed. The various factors entering the secondary fluorescence correction are grouped into three factors, representing the dependencies of the correction on specimen composition, X-ray fluorescence probability and specimen geometry. In principle, an additional factor should be appended to account for the difference in detection efficiencies of the fluoresced and fluorescing X-rays; however, this factor is shown to be within a few per cent of unity for practical applications of the secondary fluorescence correction, The absorption of secondary X-rays leaving the specimen en route to the detector is also accounted for through a single parameter. In the limit that the absorption of secondary X-rays is negligible, the geometric factor has the simple physical interpretation as the fractional solid angle subtended by the fluoresced volume from the perspective of the analysed volume, Studies of secondary fluorescence in the published literature are compared with this physical interpretation. It is shown to be qualitatively consistent with Reed's expression for secondary fluorescence in the electron probe microanalyser and with the specimen-thickness dependence of the Nockolds expression for the parallel-sided thin foil, This interpretation is also used to show that the 'sec alpha' dependence on specimen tilt in the latter expression is erroneous and should be omitted. The extent to urhich extrapolation methods can be used to correct for secondary fluorescence is also discussed, The notion that extrapolation methods, by themselves, can be used to correct for secondary fluorescence is refuted, However, extrapolation methods greatly facilitate secondary fluorescence correction for wedge-shaped specimens when used in conjunction with correction formulae.

The gels were extracted with supercritical carbon dioxide to afford a novel class of hybrid organic-inorganic aerogels. The effect of the length of the alkylene bridging group and catalyst (HCl and NaOH) on the structure was examined. The molecular structure was characterized by solid-state C-13 and Si-29 cross polarization magic angle spinning nuclear magnetic resonance spectroscopy. The alkylene bridging groups survived sol-gel polymerization to give materials with average degrees of condensation of 79 and 90% for the acid- and base-catalyzed aerogels, respectively. Scanning electron microscopy was used to examine the macroscopic structure of the gels and nitrogen sorption porosimetry was used to measure their surface areas and pore structures. Most of the alkylene-bridged aerogels were mesoporous, high-surface-area materials. As with alkylene-bridged polysilsesquioxane xerogels, the surface area decreased with increasing alkylene bridging group length. Only the base-catalyzed tetradecylene-bridged aerogel was found to be non-porous. C1 UNIV CALIF IRVINE,DEPT CHEM,IRVINE,CA 92717.

Acoustic waves in these materials were studied by Brillouin scattering. As expected, propagative phonons are observed for high-density samples. However, for some two-step samples an asymmetric profile of the Brillouin line is found which was not observed in previous investigations. This behaviour is attributed to some relaxation process coupled to the phonons. After an oxidation heat treatment these relaxations disappear. For low-density samples, the crossover to fracton modes is investigated. Values of the sound velocities, v(0), are compared for different series of samples and the data are correlated structural information.

The micro and meso pore size range can be investigated by normal small-angle X-ray scattering and possibly nitrogen adsorption. The measurement of larger pores (> 500 Angstrom) is accomplished by using combined small-angle scattering (both light and X-ray) techniques. These techniques were employed to study the change in wet gel pore structure during partial drying of alkoxide-prepared aerogel precursor gels as well as for aerogels produced from those wet gel of different solids content prepared by supercritical CO2 drying. Aerogels made with density varying from 0.17 to similar or equal to 0.6 g/cm(3) as well as the wet gel precursors showed a loss of the largest pores first during partial drying. As the degree of drying shrinkage increased, both the large pores surrounding individual aggregates and mesopores within the aggregates decreased in size,These results agree with earlier scattering studies on colloidal silica aerogels which had been isostatically compacted to different densities.

Based on an analysis of the shape of the scattering curves, the catalyst dependence of the pore and solid chords and previous work on scattering from precursor solutions, it is concluded that the structure of the aerogels results from nanoscale phase separation in the solution precursor. Remnants of a possible kinetic polymerization process were found at length scales so small that porosity arising from these processes is not penetrated by nitrogen.

V or Cu were incorporated during the solution chemistry into silica aerogels. Extrended X-ray absorption fine structure and X-ray absorption near edge structure were employed to determine that copper is present as an oxide and probably isolated in the silica matrix, while vanadium is present as V2O4 and V2O5. High resolution transmission electron microscopy and selected area diffraction were used to elucidate the characteristics of the aerogel structure itself, including the diameter of the chains, as well as to look for phase separation and crystallinity of the active metal oxide. It was found that the metals were highly dispersed in the silica aerogel, even after oxidation and reaction treatments. C1 SANDIA NATL LABS,DEPT PHYS PROPERTIES MAT,LIVERMORE,CA 94551.

However, results obtained for the copper/silica sample indicate that changes in the structure of the copper species had occurred as the sample was oxidized and exposed to reaction conditions.

An emulsion-derived macro-structure was imposed to maximize the mass transport within these high-surface-area materials. The presence of the interfacial region affects the order within the adjacent structures. Comparisons were made between carbons derived from aerogel and xerogel polymer precursors, and the effects of carbonization temperature and activation were investigated to determine the effect of processing variables on microstructural ordering at internal near-surface regions. The materials were characterized by transmission electron microscopy, scanning electron microscopy, X-ray diffraction, Raman spectroscopy and nitrogen physisorption techniques. Xerogel-derived carbons were found to have more microstructural order than carbons derived from aerogels. The degree of short-range order within the aerogel-derived carbons was observed to increase slowly with increasing pyrolysis temperature. Microporous bulk regions were found to be preferentially attacked during carbon dioxide activation. C1 SANDIA NATL LABS,DEPT PHYS PROPERTIES,LIVERMORE,CA 94550.

The present work focuses on the effect of the particle size on the transport properties of carbon aerogels of both high and low mass densities by varying the R/C ratio within the range of 50-300, the smaller R/C ratio corresponding to smaller particle size. Correlations of new results with SQUID and Raman findings identify the nanosize particles to be the localization sites for transport processes. The particle size can be estimated from the Coulomb-gap variable-range hopping model, which has been successful in explaining the low-temperature magnetoresistance data obtained for all carbon aerogels samples. The particle size thus extracted is consistent with transmission electron microscopy measurements on the carbon aerogels and is directly correlated with the R/C ratio. In polymeric carbon aerogels (R/C = 50), the average particle size becomes comparable with the width of the glassy-carbon-like ribbons within the particles, indeed blurring the distinction between particles and inter-particle links.

Silica aerogels were synthesized by two slightly different two-step polymerization processes and they were supercritically dried in a high temperature autoclave. Aerogel CS1 had a density of 9 kg/m(3) and a BET surface area of 574 m(2)/g; aerogel CS2 had a density of 30 kg/m(3) and a specific surface area of 630 m(2)/g. Both samples were fractured, vertically replicated with 0.95 nm Pt-C and backed with approximately 12 nm of rotary evaporated carbon. The silica aerogel was then removed from the replica with dilute HF acid and the replicas were studied by HRTEM. The stereoscopic HRTEM images reveal that connectors in both CS aerogels are extended filaments which resemble bottlebrushes, having microporosity. This morphology results from side-chain formation on a nearly linear CS stem. The slightly different chemistry leads to different morphologies for the two aerogels. For CS1, the connectors between stems have diameters ranging from 1.7 to 14.2 nm with an average of 6.4 +/- 0.5 nm and connector lengths averaged 62 +/- 21 nm with some as long as 132 nm. Pore sizes ranged from 13 to 240 nm with an average of 74 +/- 43 nm. The pores were slightly larger than those in CS2 which ranged from 12 to 277 nm and averaged 61 +/- 56 nm. For CS2, the connectors had diameters ranging from 1.5 to 16.5 nm and averaging 9.7 +/- 0.5 nm. The connector lengths in the CS2 aerogel averaged 58 +/- 27 nm with some as long as 127 nm. The connector diameters in CS2 (9.7 +/- 0.5 nm) were the only important aerogel feature significantly different and greater than those in CS1 (6.4 +/- 0.5 nm). The CS1 and CS2 connectors had side-chain diameters of 2 +/- 0.7 and 0.95 +/- 0.5 nm, respectively, and a similar microporosity of approximately 2.0 +/- 1 nm.

Two MF aerogels were studied. MF #1 was transparent and was formed at pH similar or equal to 2 with a bulk density of 160 kg/m(3) and a Brunauer, Emmett and Teller (BET) surface area of 970 m(2)/gm. MF #2 was an opaque aerogel formed at pH similar or equal to 0.5 with a bulk density of 130 kg/m(3) and a surface area of 850 m(2)/gm. Both MF aerogels have a polymeric nanostructure. Melamine and formaldehyde formed single polymeric chains of similar or equal to 0.95 nm in diameter. The MF #1 aerogel connectors were frequently composed of two or three polymeric chains with the connector diameter averaging similar or equal to 2.0 and similar or equal to 2.8 nm which usually showed branching every 12.6 +/- 4.5 nm thereby defining the connector length. The side chains along the connectors in MF #1 formed a reticular MF matrix. The MF #1 matrix pores averaged 10.4 +/- 5.5 nm and pores between sections of the MF matrix averaged 28.8 +/- 19 nm. In MF #2, the connectors also formed side chains but these side chains did not form a reticular matrix. As a consequence, the connector diameter, 8.8 +/- 5.8 nm, includes the side chains projecting from a core chain of 1.9 +/- 0.7 nm. In addition to the average pore size of 47.7 +/- 30 nm, MF #2 contained cavities or voids within the aerogel with length dimensions averaging 328 +/- 130 nm, responsible for its opacity. The high BET surface areas of both MF aerogels correlate with their polymeric structure. C1 LAWRENCE LIVERMORE NATL LAB,DEPT CHEM & MAT SCI,LIVERMORE,CA 94550.

In this work, relations for these quantities are derived for a gas in silica aerogel using an approach similar to that used for a gas in free space, Results for the mean free path predict that, for p greater than or equal to 10 bar, the mean free path of the gas molecules in aerogel will bs almost the same as in free space. However, as the pressure is reduced, the mean free path reaches a constant finite value instead of increasing as in free space. The thermal conductivity of a gas in aerogel starts to decrease It p = 10 bar and is almost negligible at 0.01 bar, while the thermal conductivity of a gas between parallel walls 1 cm apart starts to decrease at p = 10(-1) bar and is almost negligible at p = 10(-7) bar. The predicted thermal conductivity of a gas in aerogel is in good agreement with experimental results. C1 UNIV CALIF BERKELEY,DEPT MECH ENGN,BERKELEY,CA 94720.

Adding carbon to silica aerogel reduces thermal radiation but increases solid conduction. Whether the total energy transfer increases or decreases depends on the carbon content. This paper presents a theoretical method for determining the optimal carbon-loading level in silica aerogel to minimize the energy transfer. This method includes calculation of heat transport by coupled conduction and radiation through aerogel which is optically thin in some spectral ranges and thick in others, and the calculation of solid conductivity and spectral absorption coefficient, both of which vary with the carbon content. At ambient temperature, about 8% carbon in silica aerogel can lower the total energy transfer by about 1/3. At temperatures as high as 600 K, non-opacified aerogel has a total energy transfer that is 10 times bigger than that of opacified aerogel with optimal carbon content. The optimal carbon content that minimizes total energy transfer increases linearly with temperature. C1 UNIV CALIF BERKELEY,DEPT MECH ENGN,BERKELEY,CA 94720.

This was accomplished by constructing computer molecular models and comparing model properties with experimental data derived from small-angle X-ray scattering, nuclear magnetic resonance (NMR) and gas adsorption. Three methods are presented for obtaining models. The first method supports the concept of compacting spheres where increasing the number of contacts or coordination number reduces the surface area measured by adsorption. The second model provides a glimpse of the accessible pore size as a function of aerogel density. The last method gives a validation of the pore surface area measurement using NMR Q distributions. The understanding of aerogels can be greatly enhanced if computer models are properly generated and analyzed. However, in order to further the depth of knowledge gained from such demonstrations, more computer power will be required. C1 UNIV NEW MEXICO,NSF,CTR MICROENGINEERED CERAM,ALBUQUERQUE,NM 87131.

The objective was to produce models consistent with experimental data including scattering data, microphotographs, and density measurements. To attain this goal, aggregation techniques were used that have not been previously associated with the chemistry of neutral- and acid-catalyzed silica. The appropriateness of these techniques is argued but not addressed rigorously. The methods are unified in a single code with control parameters that allow the user to create a complete range of geometries. Characterization of the computer models is done both by calculation of the scattering function and by visualization, methods that compare directly with experimental data. The computer program embodies a combination of diffusion-limited cluster-cluster aggregation and multi-site, multi-particle diffusion-limited aggregation.

The technology itself is well enough developed as a result of extensive work over the past decade by an international community of researchers. Several substantial markets appear to exist for aerogels as thermal and sound insulator, if production costs can keep prices in line with competing established materials. In the present paper, the elements identified as key cost drivers are discussed, and a prognosis for the evolution of the technology leading to reduced cost aerogel production is given.

Using chemical vapor infiltration, a variety of solid materials were thermally deposited into the open pore structure of aerogel. The resulting materials possess new and unusual properties including photoluminescence, magnetism and altered optical properties. An important characteristic of this preparation process is the very small size of the deposits that gives rise to new behaviors. Silicon deposits exhibit photoluminescence, indicating quantum confinement. Two or more phases may be deposited simultaneously and one or both chemically or thermally reacted to produce new structures.

However, the extreme variability between individual cascades requires multiple simulations at nominally identical conditions of temperature and energy in order to assure that the comparison is statistically valid. We describe such a comparison of copper and iron in this paper. Over 600 cascades have been investigated, with simulation energies in the range 60 eV to 10 keV and temperatures from 100 to 900 K. The evolution of the cascades is similar in both materials, with the development of a highly disordered core and the emission of focusons and replacement collision sequences during the collisional phase of the cascade. The majority of vacancy-type defects are found in the cascade core when in-cascade recombination is complete, while the interstitial-type defects tend to be distributed around the periphery of this region. The final defect structure has been characterized by the total surviving defect fraction, and the number and size of the point defect clusters produced. Since these parameters have significant implications for the nuclear industry in its assessment of radiation damage, we show how they depend on cascade energy and temperature. To illustrate their importance, we provide an example of how the molecular dynamics results can be used in a rate theory model of ferritic steel embrittlement.

For the beta --> alpha reaction the nucleation rate is very low and apparently random. In general, the smaller the specimen, the greater the difficulty for nucleation. The rate of growth of the alpha phase is found to increase with decreasing temperature. The growth rate is 1.6 mm/min at 30 degrees C. For the reverse reaction, alpha --> beta, the specimens transform simultaneously independent of size. Also, the reaction nucleates at a lower temperature but grows more slowly on the first cycle. These nucleation effects are considered to be primarily due to residual stresses caused by prior transformations. The value measured for the heat of the transformation, 13.6 +/- 0.2 J/g, is lower than previously reported, and this is shown to be because the last 5 to 10% of the beta --> alpha reaction requires up to 1000 min and occurs as a continuation of the reaction that is too slow to be measured by the calorimeter.

Comparison of mismatches in BMIPP and flow tracer distribution (BMIPP < flow tracer) has demonstrated the usefulness of evaluating myocardial viability with BMIPP. BMIPP was introduced in 1993 as ''Cardiodine'' as an approved radiopharmaceutical in Japan by Nihon Medi-Physics, Inc. This article reviews the clinical use of BMIPP in the assessment of cardiomyopathy, myocardial infarction, ischemic heart disease and for the evaluation of myocardial viability in comparison with PET tracers. The results of two specific protocols demonstrating the utility of using BMIPP to detect viable myocardium are described in detail. The first study compares BMIPP and sestamibi uptake to wall motion and inotropic reserve after acute myocardial infarction in conjunction with two-dimensional echocardiography and low-dose dobutamine stimulation. The second example describes results of a triple SPECT technique using BMIPP reinjection for the assessment of ischemia. C1 FREE UNIV BRUSSELS,DEPT NUCL MED,BRUSSELS,BELGIUM.

It is established that single-phase flow of both nitrogen and water is well described by analogy to how between parallel prates. Inertial effects caused by fracture roughness become important in single-phase flow as the Reynolds number approaches 1. Foam exhibits effective control of gas mobility. Foam flow resistances are approximately 100-540 times greater than those of nitrogen over foam qualities spanning from 0.60 to 0.99 indicating effective gas-mobility control. Because previous studies of foam flow have focused mainly upon unfractured porous media, little information is available about foam flow mechanisms in fractured media. The transparency of the fracture allowed Bow visualization and demonstrated that foam theology in fractured media depends upon bubble shape and size. Changes in flow behavior are directly tied to transitions in bubble morphology. C1 UNIV CALIF BERKELEY,LAWRENCE BERKELEY LAB,DIV EARTH SCI,BERKELEY,CA 94720.

The potential for the onset of carbon monoxide oxidation on this surface was nearly 0.5 V lower than for pure Pt and approximately 0.15 V lower than for pure Ru or any Pt-Ru alloy and represents the lowest overpotential for CO oxidation ever seen in this laboratory. The potential for the onset of the oxidation of hydrogen in the presence of 0.1-2% CO coincides with the potential for the onset of CO oxidation on the alloy surface. The polarization curve for the oxidation of these gas mixtures is shifted cathodically by approximate to 0.35 V with respect to that for pure Pt.

Time-resolved optical absorption experiments are reported that involve pulsed laser excitation at 355 Mn (TiO2 bandgap) and at 410 MI (AgI bandgap). Charge carrier dynamics was probed directly by transient absorption measurements in the near-infrared and by reaction with methyl viologen (MV(2+)). Reduction of MV(2+) was observed to occur over a period of 100-200 mu s. MV(+) so produced reduced AgI to silver. By contrast, MV(2+) reduction upon bandgap excitation of neat alkaline TiO2 colloid was complete within 1 mu s. These observations signal a prolonged electron-hole separation in the case of the AgI/TiO2 sol and indicate the formation of sandwich particles.

The Na-23 NMR spectra of Na56Y, progressively exchanged with Cs+, Ca2+, and La3+ cations, respectively, indicate significantly different cation distributions in the exchanged materials. Cs+ cations preferably deplete Na+ cations from the supercage, while Ca2+ cations initially replace Na+ cations in the hexagonal prisms. La3+ cation-exchange, by contrast, is least disturbing to the relative distribution of the Na+ cations. Cs-133 magic angle spinning (MAS) experiments provide additional information on the cation distributions in the Cs+ cation-exchanged sodium zeolite Y. Interestingly, the positions of the Cs-133 resonance exhibit a significant sensitivity with respect to coexisting extraframework cations in the zeolite.

It is shown that Pauli-blocking effects are important for describing (n, alpha) processes. A sensitivity study of the results for the values of the model parameters, namely the local Fermi energy at the nuclear surface from where knockout occurs and the alpha-particle preformation factor, shows that the ranges of their variations are quite limited.

The code, dubbed SYNTH1 allows users to specify physical characteristics of a gamma-ray source, the quantity of the nuclides producing the radiation, the source-to-detector distance, the type and thickness of absorbers, the size and composition of the detector (Ge or Nal), and the electronic set up used to gather the data. In the process of specifying the parameters needed to synthesize a spectrum, several interesting intermediate results are produced, including a photopeak transmission function vs. energy, a detector efficiency curve, and a weighted list of gamma and x rays produced from a set of nuclides. All of these intermediate results are available for graphical inspection and for printing. SYNTH runs on personal computers, is menu driven and can be customized to user specifications. SYNTH contains robust support for coaxial germanium detectors and some support for sodium iodide detectors. SYNTH is not a finished product. A number of additional developments are planned. However, the existing code has been carefully compared to spectra obtained from National Institute for Standards and Technology (NIST) certified standards with very favorable results.

Coincidence gamma rays, beta spectra, and angular correlations have been added to adequately simulate a complete nuclear decay and provide corrections to experimentally determined detector efficiencies. This code has been used to strip certain low-background spectra for the purpose of extremely low-level assay. Monte Carlo calculations of this sort can be extremely successful since low background detectors are usually free of significant contributions from poorly localized radiation sources, such as cosmic muons, secondary cosmic neutrons, and radioactive construction or shielding materials. Previously, validation of this code has been obtained from a series of comparisons between measurements and blind calculations(2). An example of the application of this code to an exceedingly low background spectrum stripping will be presented. RP MILEY, HS (reprint author), PACIFIC NW LAB, BATTELLE BLVD, RICHLAND, WA 99352 USA.

The Rn-222 analyzer is based on the two-filler tube method. At the Bermuda site, monthly median Rn-222 concentrations range from similar to 50 to 700 mBq m(-3), and the concentrations vary seasonally, with a maximum in the winter and a minimum in the summer. The concentrations are significantly elevated when local winds traverse the island. At MLO, monthly median Rn-222 concentrations range from similar to 100 mBq m(-3) during the fall months to 400 mBq m(-3) during the spring months. The springtime maximum values correspond to periods of rapid transport in the free troposphere from the Asian continent, corroborated by backward air mass trajectories. The Rn-222 data are also used to help decipher local daily upslope/downslope conditions present at MLO. This study illustrates the value of atmospheric Rn-222 monitoring, when screened through the filter of local meteorology, in studying the transport of continental air to the oceans, as well as the dynamics of local meteorological effects.

Pollution prevention through source reduction and environmentally sound recycling are being pursued. General approaches to waste reductions are administrative controls, modification of process technologies, and additional waste polishing. Recycling of waste materials, such as spent acids and salts, are technical possibilities and are being pursued to accomplish additional waste reduction. Liquid waste stream polishing to remove final traces of plutonium and hazardous chemical constituents is accomplished through (a) process modifications, (b) use of alternative chemicals and sorbents for residue removal, (c) acid recycling, and (b) judicious use of a variety of waste polishing technologies. Technologies that show promise in waste minimization and pollution prevention are identified. Working toward this goal of pollution prevention is a worthwhile endeavor, not only for Los Alamos, but for the Nuclear Complex of the future.

The power law, or fractal, distribution is characterized by a fractal dimension of 0.66 to 0.79 and represents a young, immature, active fault population in a continental extensional regime. Based on this distribution. it is estimated that unobserved faults with very small displacements account for up to 6% of the total strain. Since 1.2 Ma, total extension in this part of the basin has been at least 5%. A direct correlation exists between maximum displacement and length of faults in this area suggesting that they obey a scaling relationship in which the ratio of log d(max)/log L, is 5 x 10(-3). This ratio is nearly constant for faults whose lengths span three-orders of magnitude, indicating that there is no difference in the scaling relationship of displacement and length between faults of all sizes. Considering previous models, these fault characteristics suggest that, in the western Espanola Basin: (1) host rock shear strengths are low; (2) remote shear stresses were probably high; and (3) most faults do not extend throughout the brittle crust. Finally, displacement profiles on five of the largest faults are asymmetric and show a rapid decrease in displacement from the point of maximum displacement toward the fault tip. The fractal nature, scaling relationship and distribution of displacement on faults are used to suggest that faults grew by nearly proportional increases in displacement and length, perhaps by mechanisms dominated by propagating shear fractures rather than by linkage of pre-existing joints or faults.

Smokeless ashtrays are designed to reduce ETS exposure by removing particulate and/or gas-phase contaminants from this plume. This paper describes an experimental investigation of the effectiveness of four smokeless ashtrays: two commercial devices and two prototypes constructed by the authors. In the basic experimental protocol, one or more cigarettes was permitted to smolder in a room. Particulate or gas-phase pollutant concentrations were measured in the room air over time. Device effectiveness was determined by comparing pollutant concentrations with the device in use to those obtained with no control device. A lung deposition model was applied to further interpret device effectiveness for particle removal. The commercial ashtrays were found to be substantially ineffective in removing ETS particles because of the use of low-quality filter media and/or the failure to draw the smoke through the filter. A prototype ashtray using HEPA filter material achieved better than 90% particle removal efficiency. Gasphase pollutant removal was tested for only one prototype smokeless ashtray, which employed filters containing activated carbon and activated alumina. Removal efficiencies for the 18 gas-phase compounds measured (above the detection limit) were in the range of 70 to 95%.

The Knoop microhardness of several orientations on the (100) plane of both the irradiated and unirradiated crystals mere measured with different indentation loads. The change in hardness profile of the crystals was almost the same after the two irradiation conditions. The hardness increased by 4-15% because of the irradiations depending on the crystallographic orientation, the larger change being observed at orientations between the [001] and [011] directions. While both the {111}[1(1) over bar0$] and {110}[1(1) over bar0$] slip systems are simultaneously active in the unirradiated MgO . 3Al(2)O(3), the {111}[1(1) over bar0$] system may be the dominant slip system in the neutron-irradiated crystals. It is concluded that the restriction of the {110}[1(1) over bar0$] slip system is caused by irradiation-induced interstitial ions. C1 TOKYO INST TECHNOL,DEPT INORGAN MAT,MEGURO KU,TOKYO 152,JAPAN.

The effect of such conditions on the reliability of the ceramic was estimated by comparing the Weibull modulus of the groups of specimens, tested in four-point flexure, before and after exposure. The Weibull modulus of as-polished specimens was 6.7, indicating a wide variation in room-temperature flexural strength. The Weibull modulus was increased to 14.2 by the heat treatment for 2 h in wet H-2 at 1400 degrees C. The average strength was also improved from 347 to 446 MPa by such exposure. Heat treatment at 1300 degrees and 1500 degrees C also improved the reliability of the material, as indicated by increases in the Weibull modulus, but to less a degree than did exposure at 1400 degrees C. The increases in reliability and average strength were attributed to the blunting of surface flaws by the formation of a thin SiO2 layer on the sample surface.

An extended mass-to-charge ratio range quadrupole mass spectrometer was employed to examine the effects of harsher conditions in the ESI atmosphere-vacuum interface region on the streptavidin tetramer. Thermally induced dissociation caused the mass spectra to exhibit a series of complementary monomer and trimer ions that correspond to decomposition of the tetrameric species. Similar results were obtained with tandem mass spectrometric experiments on a Fourier transform ion cyclotron resonance mass spectrometer by application of sustained off-resonance irradiation (SORI) on a selected tetrameric charge state. The technique of single-frequency quadrupole excitation was used to accomplish selected-ion accumulation of the 14 + charge state of the tetramer during ion injection. Subsequent low energy SORI combined with broadband quadrupole cooling produced the 7 + monomer and 7 + trimer species, as well as the 6 + monomer and 8 + trimer complementary ions. The observed asymmetric breakup of the tetramer is qualitatively explained by using physical models. C1 PACIFIC NW LAB, DEPT CHEM SCI, CHEM METHODS & SEPARAT GRP, RICHLAND, WA 99352 USA.

Three general observations were made: (1) the ion-ion reaction rate constants were estimated to be 10(-(7-8)) cm(3) ion(-1) s(-1); (2) the ion-ion reaction rates were found to be dependent on the reactant ion number density, which could be controlled by both the reactant ion number and the pseudopotential well depth, and (3) very little fragmentation, if any, was observed, as might normally be expected with highly exothermic proton transfer reaction.

We measure a complete set of transport properties nics for one particular binary salt solution: sodium trifluoromethanesulfonate in poly(ethylene oxide), over a wide range of salt concentrations (0.1 to 2.6M) at a particular temperature (85 degrees C). The transport properties measured include the conductivity, the salt diffusion coefficient, and the sodium ion transference number. The mean molar activity coefficient of the salt is also the determined. The conductivity is measured using the standard ac impedance method. The salt diffusion coefficient is found by using the method of restricted diffusion. The conductivity and diffusion coefficients of NaCF3SO3 are similar in magnitude to those of LiCF3SO3 in poly(ethylene oxide). The transference number and thermodynamic factor are found by combining concentration cell data with the results of galvanostatic polarization experiments. This novel method of measuring the transference number is straightforward to perform experimentally and yet does not require that the solution be either dilute or ideal. A theoretical analysis of the experimental method based on concentrated,solution theory is given. Our study verifies that the transference numbers derived from the experiments retain fundamental significance in applications involving both steady and transient processes and in systems coupling the polymer electrolyte with electrodes of all types (stoichiometries). The relevant transference numbers can be determined independently of any knowledge of speciation of the polymer electrolyte. The transference numbers found here for the sodium ion are much lower than those reported for the lithium ion, especially in the concentrated solutions. The transference number of the sodium ion is negative in the more concentrated solutions and levels off at its maximum value of 0.31 in the dilute concentration range. The transference number results are interpreted in terms of complexation of the sodium ion with the anionic species.

J-V and flatband potential measurements indicate that the deviation of the J-V curves from the ideal square-like shape to S shape is due to the light-induced displacement of the bandedges. Analytical expressions describing the dependence of light-induced bandedge shifts on the anodic photocurrent, the density of surface states, and the interfacial charge-transfer velocity are derived and verified experimentally Application of the expressions to J-V data yields quantitative information on the kinetics of interfacial charge transfer.

We report on the corrosion characteristics of melt-spun ribbons of Al90Fe10-x Ce-x (x = 3, 5, and 7). The amorphous alloys showed excellent corrosion properties in aqueous NaCl. We have also examined the composition, structure, and morphology of the native and passive oxide films using scanning electron microscopy (SEM), x-ray photoelectron spectroscopy (XPS), and angle-resolved XPS. We show that the composition of the native oxide film is that of Alo(x)(OH)(y). The thickness of the native oxide is estimated from angle-resolved XPS data to be about 1.6 to 3.1 nm (i.e., nanometer). Passive films were formed in 0.9 weight percent (0.15M) NaCl solution by potentiostating below the pitting Potential for 30 and 60 min. The passive oxide films contain oxidized Al, Fe, and Ce. The chemistry of Al in the passive oxide films is also that of AlOx(OH)(y). Iron appears to be present in the passive film as Fe3O4 and Fe2O3 and/or FeOOH with varying mole fractions depending on alloy composition. Cerium in the passive film appears to be present in the +3 oxidation state as Ce2O3 or Ce(OH)(3). A small fraction of Ce in the passive film of Al90Fe3Ce7 is present in the +4 oxidation states as CeO2. C1 ARGONNE NATL LAB,ARGONNE,IL 60439.

We have demonstrated that the Cu++/Cu+ reaction is strongly catalyzed by trace amounts of chloride ions in the solution. The Cu+/Cu reaction was found to be unaffected by chloride ions. These experimental results were also substantiated by theoretical calculations. We have investigated the electronic coupling for homogeneous electron-transfer reactions that are approximate models for electron transfer in the copper deposition: (i) outer-sphere reaction (water-water bridge), and (ii) inner-sphere reaction (chloride bridge). For Cu++/Cu+ electron transfer we found increased coupling for the chloride bridge, which we attribute to the closer approach found for this complex compared to the water bridge, while for Cu+/Cu electron transfer, coupling was not increased for the chloride bridge reaction.

The results indicated that an Li film vapor-deposited on to a nickel (Ni) substrate can be reversibly evaporated from the substrate by heating the sample to 850 K. No Li diffusion into, and alloying with, Ni were observed at any temperature between 200 and 850 K upon annealing. Annealing an Ni substrate covered by an Li-oxide film at 1100 K also produced an Li-free Ni substrate. The results show definitively that Ni is an inert substrate for Li deposition.

Subsurface respiration in Sycamore Creek is highest in regions of hydrologic downwelling where organic matter derived from the stream surface is transported into the hyporheic zone. Similarly, nitrification was closely related to hydrologic exchange between the surface and hyporheic zone. Nitrification in downwelling regions averaged 13.1 mu gNO(3)-N . L sediments(-1). h(-1) compared with 1.7 mu gNO(3)-N . L sediments(-1). h(-1) in upwelling regions. Hyporheic respiration also varies temporally as a result of flash floods which scour and remove algae from the stream and thus reduce the pool of organic matter to support subsurface metabolism. Nitrification was also significantly affected by flooding; nitrification increased from an average of only 3.0 mu gNO(3)-N . L sediments(-1). h(-1) immediately following floods to 38.5 mu gNO(3)-N . L sediments(-1). h(-1) late in succession. Nitrification was significantly correlated with hyporheic respiration, supporting the hypothesis that nitrification is fueled by mineralization of organic nitrogen to ammonium. The coupling between subsurface respiration and nitrification is one step in a cyclic interaction between surface and hyporheic zones and serves to transform nitrogen from an organic to inorganic form.

Ceramic tiles supporting moderate levels of periphyton were placed in laboratory microcosms and exposed to nickel ion and C-14-labeled sodium bicarbonate. Sorption of nickel increased hyperbolically as light intensity increased fron zero to 300 mu mol quanta m(-2) s(-1); this response was similar to the photosynthesis-irradiance relationship for periphyton collected from the same site. Nickel sorption with light was up to 76% greater than nickel sorption in the dark. Dark-related nickel sorption was likely attributable to sorption by hydrous iron and manganese oxides and to passive biotic sorption. These results suggest an important relationship between nickel sorption and photosynthesis, which may be a result of active uptake, absorption through cation exchange, or nickel precipitation.

This cross section cannot be observed directly. Instead, pairs of measurements of laser intensities and Rayleigh scattering counts are observed. Our aim is to provide estimators for the probability density function of the scattering cross section from such measurements. The probability distribution is derived first for the number of recorded photons in the Rayleigh scattering experiment. in this approach the laser intensity measurements are treated as known covariates. This departs from the usual practice of normalizing the Rayleigh scattering counts by the laser intensities. For distributions supported on finite intervals two estimators of the probability density are given: one based on expansion of the density in orthonormal polynomials and the other based on the maximum likelihood. The latter procedure is applied to Rayleigh scattering data from an open V-shaped premixed methane-air flame. C1 UNIV CALIF BERKELEY,DEPT MECH ENGN,BERKELEY,CA 94720.

However, for waste pollution there was a positive correlation found between the media agenda and real-world conditions.

A linear solvation energy relationship derived for solid fullerene at 298 K was used to calculate gas/solid partition coefficients for the same vapors as those examined using the vapor sensor. This relationship correctly predicted; the relative vapor sensitivities observed with the vapor sensor. A new linear solvation energy relationship for vapor adsorption by graphite at 298 K has been determined, and solid fullerene and solid graphite are found to be quite similar in their vapor sorption properties. Comparisons have also been made with linear organic and inorganic polymers, including poly(isobutylene), poly(epichlorohydrin), OV25, and OV202. In all cases, sorption is driven primarily by dispersion interactions. The assembled fullerene material is generally similar in vapor selectivity to the other nonpolar sorbent materials considered but yields less sensitive vapor sensors than linear organic polymers.

Identical,results were found with both methods. Pb atoms are deposited underpotentially on Cu(111) into a compact nonrotated hexagonal overlayer. The measured Pb coverage at saturation is 53% with respect to the Cu(111) substrate and is identical to the packing density of the (111) plane of bulk Pb. The presence of Cl- in the supporting electrolyte has a strong effect on the potential region where deposition/stripping occurs and on the reversibility of the reaction.

These mutations, many of which are deletions, were recovered by the specific-locus mutagenesis technique. Previous analysis of a panel of brown deletions, generated at Oak Ridge, has enabled both a preliminary molecular and a functional map around the locus to be generated. We have used a panel of hybrid DNA from 25 Oak Ridge deletions, where the deleted chromosome was heterozygous with a Mus spretus chromosome, to map polymorphic markers including microclones, microsatellites, and cloned DNA markers. We have generated a fine structure map, based on 25 new markers, of an 8.5-cM region surrounding the brown locus. This map will prove useful in future mapping studies of this region and in the isolation of the genes that lie within it. C1 OAK RIDGE NATL LAB,DIV BIOL,OAK RIDGE,TN 37831.

YBCO films on polycrystalline Ni/NiO, Inconel 600, and Inconel X substrates ranging in-thickness from 80-100 mu m have been developed by a three-step process with observed T-c zero values up to 85 K. In the first step, the metallic substrates were examined with and without a preoxidation anneal to form a native oxide layer. Second, superconducting YBCO powder (0.2 mu m particle size) was mixed with ethanol and sprayed onto the substrates. Third, the films were sintered at high temperature and oxygenated to form the superconducting phase. The effect of a native oxide buffer layer upon superconducting properties was evaluated as a function of the duration of the preoxidation anneal and the sintering anneal. X-ray diffraction (XRD) theta/2 theta, variable temperature four-probe resistance, and Auger line scan characterization of these films will be discussed.

Various forms of interpenetrating-phase and dispersed-phase microstructures are produced by means of these reactions. It is also apparent that both composition and morphology can be manipulated to some degree in order to tailor composite structures. The composition and morphology of MoSi2 reinforced with SiC particles was explored over a wide range by controlling starting reactant compositions and hot-pressing conditions. Preliminary results of a model for the formation of the MoSi2/SiC composite are presented in which both diffusion and interfacial reactions are included. Strength in bending and chevron-notch fracture toughness were determined as a function of temperature and composition and the measured properties are discussed with regard to the observed microstructures. A novel, graded composite structure in the NiAl/Ni3Al/Ni:Al2O3 system is also discussed. C1 UNIV WASHINGTON, DEPT MAT SCI & ENGN, SEATTLE, WA 98195 USA.

We have studied the tensile creep properties of annealed 62Cu-35Au-3Ni alloy over the temperature range 250 degrees C to 750 degrees C. Two power-law equations have been developed for the minimum creep rate as a function of true stress and temperature. At the highest temperatures studied (650 degrees C and 750 degrees C), the minimum creep rate is well described with a stress exponent of 3.0, which can be rationalized in the context of Class I solid solution strengthening. The inverted shape of the creep curves observed at these temperatures is also consistent with Class I ahoy behavior. At lower temperatures, power-law creep is well described with a stress exponent of 7.5, and normal three-stage creep curves are observed. Intergranular creep damage, along with minimum values of strain to fracture, is most apparent at 450 degrees C and 550 degrees C. The lower stress exponent in the Class I alloy regime helps to increase the strain to fracture at higher temperatures (650 degrees C and 750 degrees C). The minimum creep rate behavior of the 62Cu-35Au-3Ni alloy is also compared with those of the 74.2Cu-25.8Au alloy and pure Cu. This comparison indicates that the 62Cu-35Au-3Ni has considerably higher creep strength than pure Cu. This fact suggests that the 62Cu-35Au-3Ni braze alloy can be used in low mismatch metal-to-ceramic braze joints such as Mo to metallized alumina ceramic with few problems. However, careful joint design may be essential for the use of this alloy in high thermal mismatch metal-to-ceramic braze joints.

Experimental quasi-static and dynamic deformation data are used to formulate the constitutive description based on the mechanical threshold stress model (MTS). The MTS model is used to predict the deformation behavior of U-Ti and W-alloy beyond the conventionally achievable experimental capabilities. We suggest that uranium alloys are more prone to catastrophic-localized deformation (adiabatic shearing) due to the existence of a soft high-temperature phase, which is reached by uranium alloys undergoing large strains at high strain rate of deformation.

The width of each layer and the spacing between layers have been shown to be inversely proportional to velocity, and the proportionality constants depend upon the nucleation temperatures for the two phases. The nucleation temperatures for the two phases are shown to play a critical role in the formation and stability of layered structures. The range of compositions over which layered structures can form is identified, and it is shown that convection effects in the liquid will destabilize the layered structure. Several key experimental studies have been identified to evaluate minimum undercoolings required for the nucleation of each of the two phases. The morphology of the transition interface is shown to depend upon the relative effects of nucleation and growth of the two phases. C1 IOWA STATE UNIV SCI & TECHNOL,US DOE,AMES LAB,AMES,IA 50011.

The inhomogeneous distribution of particulate uranium phases in the soil required the development of a method for using ultramicrotomy to prepare transmission electron microscopy (TEM) thin sections from the SEM mounts. A water-miscible resin was selected that allowed comparison between SEM and TEM images, permitting representative sampling of the soil. Uranium was found in iron oxides, silicates (soddyite), phosphates (autunites), and uraninite (UO2+x). No uranium was detected in association with phyllosilicates in the soil.

The most common enclave type is layered, rich in biotite, cordierite and aluminosilicates, and has textures and compositions that reveal variable degrees of melt extraction from metasedimentary source rocks. Rare sillimanite-bearing enclaves represent residual material, either from the region of magma generation or its ascent path, but most such enclaves were probably derived from the contact aureole closer to the present level of exposure. These non-igneous enclaves (NIE) and their disaggregation products are present in all major plutons, comprising from < 2 to 5 vol.% of the granites. Enclaves of igneous origin are also present in all major plutons except Carnmenellis, generally comprising < 1 vol.% of the granites. The most common type is intermediate in composition, with microgranular texture, and mineral compositions and textures consistent with an origin by magma mixing. Large crystals of K-feldspar, plagioclase and quartz, common in these microgranular enclaves (ME) but absent in NIE, represent phenocrysts derived from the silicic end-member during magma mixing events rather than products of metasomatism as suggested previously. Although the composition of the mafic end-member (basaltic or lamprophyric) involved in the mixing process is poorly constrained, the presence of ME in the granites, and the preponderance of mantle-derived mafic rocks in the coeval Exeter Volcanics, indicate that mafic magma injection into the crust was a factor in the generation of the batholith. Advection of sub-crustal heat provides an explanation for large-volume crustal melting in regions of relatively thin crust such as southwest England.

About one-half of the sequence information in effect was accessed by conventional recognition-site assays of the entire mtDNA molecule; the remainder came from direct sequence assays of a normally hypervariable 5' section of the noncoding control region. The two assay methods produced essentially nonoverlapping sets of variable character states that were compared with respect to magnitudes and phylogeographic patterns of mtDNA variation. The two assay procedures yielded nearly identical outcomes with regard to: (a) total levels of species-wide mtDNA genetic variation; (b) mean levels of within-locale variation; (c) extremely high population genetic structure; (d) a phylogenetically significant separation of samples from the north-western half of the species' range vs. those in the south-eastern segment; and (e) considerably lower genetic variability within the north-western clade. The micro- and macro-phylogeographic mtDNA patterns in the musk turtle are consistent with a low-dispersal natural history, and with a suspected longer-term biogeographic history of the species, respectively.

A generalized chi(2) statistic is defined in terms of 'observable' quantities: the genus and spot density that would be measured by different cosmic observers. This strategy, together with the use of Monte Carlo simulations of the temperature fluctuations, including all the relevant experimental parameters, represents the main difference from previous analyses. Based on the genus analysis we find a strong anticorrelation between the quadrupole amplitude Q(rms-PS) and the spectral index n of the density fluctuation power spectrum at recombination of the form Q(rms-PS) = 22.2 +/- 1.7 - (4.7 +/- 1.3)x n mu K for fixed n, consistent with previous works. The result obtained based on the spot density is consistent with this Q(rms-PS)(n) relation. In addition to the previous results, we have determined, using Monte Carlo simulations, the minimum uncertainty due to cosmic variance for the determination of the spectral index with the genus analysis. This uncertainty is delta n approximate to 0.2. C1 CTR INT FIS,BOGOTA,COLOMBIA. UNIV CALIF BERKELEY,LAWRENCE BERKELEY LAB,BERKELEY,CA 94720.

The 6C and B2 samples are selected at a flux density level at which the differential source counts exceed by the greatest amount the counts predicted for a non-evolving Friedmann cosmology. The new observations presented here complete a set of high-quality radio data for these samples: in conjunction with new optical/infrared data they should provide new insight into the cosmological evolution of this source population. The sources were observed with the VLA, at one or more of the following frequencies: 1.4 GHz, 5 GHz, 8.4 GHz. Basic source parameters are derived from each image, Images of individual sources are briefly discussed. The sources are classified morphologically according to their degree of core dominance R. The distributions of morphologies for 3CR and '6C/B2' sources are compared and discussed. C1 MULLARD RADIO ASTRON OBSERV,CAVENDISH LAB,CAMBRIDGE CB3 0HE,ENGLAND.

With respect to the upstream flow, the convective system formed in the lee with rainfall totals from this system exceeding 100 mm. Any event that produces over 100 mm of rain in 24 h is thought to be capable of producing flooding over the steep orography of Taiwan. Analysis of Doppler radar data showed that the convective cells during this heavy rainfall event repeatedly formed near a fixed location over the foothills and moved slowly (similar to 4 m s(-1))northward. Although the radar reflectivities within these cells were relatively modest (35-40 dBZ), the repeated passage of slowly moving cells partly supplemented by relatively steady, stratiform rainfall during the later stages of the event resulted in the high precipitation totals. The heavy rain in this event resulted from a number of factors including 1) a moist, convectively unstable southerly Bow of tropical origin, 2) a shallow convergence zone on the western side of the island dividing Bow with a northerly component from that with a southerly component, 3) a quasi-stationary area of storm formation, and 4) a mesoscale environment that produced convective systems with a favorable storm structure and movement. Due to the fact that the large-scale forcing-as evidenced by vertical ascent calculated using rawinsonde data-was small, the authors believe that the conceptual model of low-Froude number Bow around the island of Taiwan in the presence of heating can be used to explain the local convergent region that initiated this convective event. A numerical simulation of flow around the island of Taiwan in the presence of surface heating predicted a persistent quasi-stationary area of convergence in the foothills near the location of the observed convection. In this study the hypothesis is discussed that this persistent, quasi-stationary area of convergence may have also played a role in maintaining this convective system. These results and the application of this conceptual model will be discussed within the more general context of forecasting Bash hoods in Taiwan and the United States.

Microscopy and diffraction analyses have shown that the sputter deposited structures are epitaxial with crystalline interfaces. The amorphization reaction nucleates at the multilayer interfaces, i.e. the lattice sires of disorder. The interfacial disorder that arises from lattice distortions is dependent on the layer pair spacing. The onset temperature of SSA as measured using differential thermal analysis is shown to depend on the layer pair spacing.

The isotypic variety(2) and conformational flexibility of tubulin have so far made it impossible to obtain crystals for X-ray work(3). Structural knowledge of tubulin has been limited to about 20 Angstrom from X-ray diffraction of oriented microtubules(4), and from electron microscopy of microtubules and zinc-induced crystalline sheets in negative stain(5,6). The sheets consist of protofilaments similar to those in microtubules but associated in an antiparallel arrangement(7) and their two-dimensional character is ideal for high-resolution electron microscopy(8,9). Here we present a three-dimensional reconstruction of tubulin to 6.5 Angstrom resolution, obtained by electron crystallography of zinc-induced two-dimensional crystals of the protein, The alpha- and beta-subunits appear topologically similar, in agreement with their sequence homology(10). Several features can be defined in terms of secondary structure. An apparent alpha-helical portion, adjacent to both interdimer and inter-protofilament contacts, is tentatively attributed to a segment near the carboxy terminus of the protein. We can assign the alpha- and beta-subunits on the basis of projection studies of the binding of taxol*, which show one taxol site per tubulin heterodimer, in agreement with the known stoichiometry of taxol in microtubules(11). These studies indicate that taxol affects the interaction between protofilaments; to our knowledge, this is the first time that a ligand-binding site has been visualized in the tubulin molecule.

The inspection system, based on using a laser vibrometer to measure the response of containers to acoustic excitation, is capable of detecting subtle changes in vibration characteristics due to variations in the physical properties of different fill materials. Determination of fill type is achieved by applying a k-nearest neighbour classification tree analysis to the resulting acoustic resonance data. Application of the method to field trial measurements of chemical weapons shows the inspection system to be a practical and reliable means for discriminating between munitions with a variety of chemical fills.

The small detector sizes and fast scintillation fluors available make them very promising for use at high luminosity experiments at today's and tomorrow's colliding and fixed target experiments where high rate capability is essential. This paper will discuss the current state of scintillating fiber performance and current Visual Light Photon Counter (VLPC) characteristics. The primary topic will be some of the system design and integration issues which should be considered by anyone attempting to design a scintillating fiber tracking system which includes a high speed tracking trigger.

By coating a thin-layer of low-resistive, electronically-conductive glass on various substrates (including quartz and ceramics), we built MSGCs of high gain stability and low leakage current. They were tested in Ar-CH4(10%) and He-C2H6(50%) gas mixtures. Energy resolutions of 17-20% were measured for 6 keV X-rays. This design can make the choice of substrate less important, save the cost of ion-implantation, and use less glass material. Micro Gap Chamber was successfully tested in He-C2H6(50%) and Ar-C2H6(50%) gas mixtures. Energy resolutions of about 20% were obtained. Both detectors are expected to have high rate capability.

This detector was conceived and developed at CERN and built at DEP for elastic scattering measurements at the Tevatron and future colliders. Two pairs of such detectors, symmetric in the vertical plane, will be located along the beam pipe at either side from the interaction point E0 in the Tevatron. The first detector has been recently installed by the E811 collaboration and is being tested with beam halo. Another one is being tested in a cosmic ray setup. Preliminary results are presented from both configurations and agree with preliminary tests performed at CERN/PS. C1 CORNELL UNIV,ITHACA,NY 14853. FERMILAB NATL ACCELERATOR LAB,BATAVIA,IL 60510.

Two preamplifier versions that differ for the resistivity of the channel region have been realised. The lower channel resistivity is employed in applications from room temperature to liquid krypton, while the higher one suits the operation at liquid argon temperature. The paper describes the essential features of the two types of preamplifier, including the radiation sensitivity to gamma-rays and neutrons at room temperature and the noise performances at cryogenic temperature.

With respect to the present system, the upgraded trigger system must operate faster and provide a higher degree of background rejection while extending the physics acceptance beyond that of the current system. This will be accomplished in part by incorporating the scintillating fiber tracker and the preshower detector into the Level 1 trigger. Track logic, implemented in commercial FPGAs, will be used to identify tracks in the scintillating fiber tracker with P-T > 1.5 GeV/c and electron candidates in the preshower detector. Integration of the trigger logic and readout electronics permits the identification of all tracks in a few hundred nanoseconds. Here, preliminary designs for the readout and trigger electronics are presented along with simulation results for trigger efficiencies and rejection factors. C1 CBPF,LAFEX,RIO JANEIRO,BRAZIL.

The CFLT uses a pipelined architecture to accept and analyze calorimeter data for every 96 ns beam crossing interval. PMT signals are combined by analog electronics into electromagnetic and hadronic sums for 896 trigger towers. The analog sums are then digitized and analyzed. The CFLT determines the total, transverse, and missing transverse energy, identifies isolated electrons and muons, and sums energies in programmable subregions. Calculations are performed in 96 ns steps, and new data are accepted for every beam crossing. Trigger data are forwarded to the global first level trigger (GFLT) after 2 mu s, allowing a GFLT accept to be issued 5 mu s after the beam crossing which produced the event. Important features of the CFLT include a 12-bit effective dynamic range, extensive use of memory lookup tables for trigger calculations, fast pattern searches for isolated leptons, and low electronics noise. During the 1993 HERA run, the CFLT reduced a 50 kHz background rate to around 100 Hz. C1 ARGONNE NATL LAB,ARGONNE,IL 60439. RP SILVERSTEIN, S (reprint author), UNIV WISCONSIN,MADISON,WI 53706, USA.

It has been found that moderate resistivity (300-700 Omega cm) silicon detectors, after being irradiated from 5.0 X 10(13) to 2.0 X 10(14) n/cm(2), are extremely stable in terms of the detector full depletion voltage (V-d) or the net effective concentration of ionized space charges (N-eff) - there is little ''reverse annealing'' of N-eff at RT and elevated temperatures, as compared with large reverse annealing observed for high resistivity silicon detectors. Detectors with starting resistivity of 300-700 hi cm have been found to be stable, during the equivalent of one year RT anneal that would reach the saturation of the first stage of reverse anneal, within the N-eff window of \N-eff\ less than or equal to 2.5 X 10(12) cm(-3) (V-d = 180 V for d = 300 mu m) in a working range of 5.0 x 10(13) to 1.5 X 10(14) n/cm(2), or a net neutron radiation tolerance of 1.0 X 10(14) n/cm(2). The observed effects are in very good agreement with an early proposed model, which predicted among others, that there might be an off-set between the reverse annealing effect (increase of net acceptor-like ionized states in the space charge region with time) and the partial annealing of the P-V centers that leads to the partial recovery of the shallow impurity donors (phosphorus in this case). Study on detectors with various starting resistivities has indicated an optima starting resistivity of about 1.6 k Omega cm for which the detector full depletion voltage is under 180 V for a 280 mu m thick detector before and after neutron radiation and after reverse anneal.

In the experiments transient current and charge techniques, with short laser light pulse excitation, have been applied in the temperature range of 77-300 K. Light pulse illumination of the front (p(+)) and back (n(+)) contacts of the detectors showed effective trapping and detrapping for electrons and holes. At temperatures lower than 200 K, the detrapping becomes inefficient, and the additional charge of trapped non-equilibrium carriers in the space charge region (SCR) of the detectors leads to dramatic transformations of the effective space charge concentration N-eff and electric field. The current and charge pulses transformation data can be explained in terms of extraction of electric field to the contact opposite to the illuminated one. C1 BROOKHAVEN NATL LAB,UPTON,NY 11973.

We focus on chemisorbed NO and ammonia on Pd(111) and compare our results with the latest experimental information. We then turn to two aspects of excited-stare PESs. First, we compare first-principles calculations of the forces on an ammonia ion as a function of distance from the surface. We find that the image-charge model fails significantly at distances which are the most relevant for dynamics, closer than similar to 3 Angstrom, and discuss reasons for the failure. We then summarize a purely electronic adiabatic model of the molecule-surface bond and use empirical parameters to estimate hot carrier-produced excited states of chemisorbed NO. We find multiple PESs and a novel interpretation of the pi* resonance, seen in inverse photoemission. C1 BIOSYM TECHNOL INC,SAN DIEGO,CA 92121.

Specifically, we present an analysis of the 6-350 eV electron-induced desorption and dissociation of chemisorbed NH3 and ND3 on Pt(111). State-selective detection of the neutral DIET products is accomplished by 2 + 1 resonance-enhanced multiphoton ionization (REMPI). Desorption and dissociation occur as a result of distinct electronic excitations that result in different, uncoupled, modes of intramolecular motion. We find that desorption results from 3a(1)(-1)-induced inversion motion. Trajectories on a two-dimensional potential energy surface reveal that the excited molecule fully inverts; upon deexcitation, the inverted molecule is sufficiently high on the hard wall of the substrate interaction to have enough energy to desorb. Given the short excitation lifetime, the time scale in which the (H) D atoms reach the inversion geometry directly affects the desorption yield and results in an appreciable enhancement of NH3 desorption over that of ND3. In general, multidimensional molecule-surface potential energy surfaces should be considered in DIET processes involving molecular adsorbates.

The D-2 desorbates have very little translational energy( similar to 20-50 meV) but are vibrationally (upsilon = 0-4) and rotationally (J = 0-12) excited. The rotational state distribution of the D-2 does not change as the ice temperature increases from 88 to 145 K. However, we find that the D-2 yield increases monotonically in this temperature range, with the yield at 145 K approximately double than that at 88 K. Although the mobilities of defects, charge carriers, and radicals are known to be temperature dependent, these results suggest that the final states leading to D-2 production are independent of temperature. We suggest that the dominant mechanisms for production of D-2 at 100 eV incident electron energy are dissociative recombination of holes (D2O+ or D3O+) with quasi-free or trapped electrons and dissociation of excitons at the vacuum-surface interface. These dissociation events can produce D-2 directly via molecular elimination or indirectly via reactive scattering of the energetic D atom fragments.

We employ large-scale matrix diagonalization involving greater than or equal to 1000 basis states and realistic effective single-particle potentials. We implement two complementary techniques - the complex rotation method and the stabilization method. We also investigate strongly perturbed atomic wave functions near the surface and relate their evolution as a function of the distance, d, to the Wigner-von-Neumann non-crossing rule. The distance dependence of the resonance parameters can be analyzed in terms of semiclassical mechanics. C1 OAK RIDGE NATL LAB,OAK RIDGE,TN 37831.

Our model accounts for both dynamic image interactions and multiple scattering near the surface and predicts a pronounced convoy electron peak for small emission angles. We find that convoy electrons principally originate from target core states which are excited via close collisions with the impinging ions. Polarization of core electrons during emission is found to play an important role. Very good agreement is found with experiments for fast Li+ ions interacting with SnTe(0,0,1) surfaces.

We report here our first discovery, a supernova at z = 0.458 (SN1992bi) and the ongoing analysis on several new supernova candidates found in a recent search (Dec 93 - March 94). The photometry for SN1992bi closely matches the lightcurve calculated for its redshift from the template of well-observed nearby Type Ia supernovae giving a best fit value for the deceleration parameter: q(O) = 0.1 +/- 0.3 (+/- 0.55) (with Lambda = 0), where the first uncertainty is due to the photometry of the distant supernova and the second reflects the estimated intrinsic width of the Type Ia absolute magnitude distribution based on nearby supernovae. If there is significant host galaxy extinction then q(O) would be larger than this best fit value. We describe the main sources of measurement error inherent in such a measurement of q(O), and ways to reduce these errors. C1 INST ASTRON,CAMBRIDGE,ENGLAND. UNIV DURHAM,DURHAM,ENGLAND.

There is a connection between anisotropy in the CMB and the topology of the Universe. Adopting a universe with the topology of a 3-Torus, or a universe where only harmonics of the fundamental mode are allowed, and using a-years of COBE/DMR data, we obtain constraints on the topology of the Universe. We obtain more accurate results than previous work by using all multipole moments, avoiding approximations by computing their full covariance matrix. The best fit for a cubic toroidal universe is obtained at a scale of 7200h(-1)Mpc for n = 1. The data set a lower limit on the cell size of 4320h(-1)Mpc at 95% confidence and 5880h(-1)Mpc at 68% confidence. These results show that the most probable cell size would be around 1.2 times larger than the horizon scale, implying that the 3-Torus topology is no longer an interesting cosmological model.

For verification of the new program option, calculations of the reactivity worths of the control rod and the safety rod of the FOEHN reactor and the reactivity effects of various components in the reflector pool of the FOEHN reactor were performed with both KCODE and KCORR and compared with measured data. The efficiency of MCNP in calculating reactivity changes by using KCORR is improved not only by means of lower statistical uncertainties but also by reduction of computing time.

This model is applied primarily to a fluid-fuel blanket concept for an ATW that generates net electric power from the fissioning of spent commercial reactor fuel. An important goal of this study is the development of essential parametric trade-offs to aid in any future conceptual engineering design of an ATW that would burn spent commercial fuel and generate net electric power. As such, costing procedures and methodologies used to estimate and compare advanced nuclear power generation systems are applied. Hence, the cost of electricity (COE) (in mills per kilowatt-hour) is adopted as the primary object function with which to examine parametrically key system trade-offs; other costs, such as unit cost of installed (net) po wet [in dollars per watt (electric)] total cost (in dollars), fetal lifecycle cost (in dollars), and cost of product (in dollars per kilogram) are also reported. The COE required by an electrical power-generating ATW fueled with spent commercial fuel is generally found to be above that projected for other advanced fission power plants. The accelerator and the chemical plant equipment cost accounts are quantitatively identified as main cost drivers, with the capital cost of radio-frequency power dominating the former. Significant reductions of this cost differential are possible by increased blanket neutron multiplication, increased plant capacity, or increased thermal-to-electric conversion efficiency. The benefits of reduced long-lived fission products and. spent commercial fuel actinides provided by the ATW approach translate into a less tangible source of revenue to be provided by a charge that must be levied on the client fission powerplants being serviced. The main goal of this study, however, is not a direct cost comparison but is instead a quantitative determination of cost-based sensitivity of key cost drivers and operational modes for an ATW concept that would address the growing spent commercial fuel problem; parametric results presented focus on this goal, and a specific ATW ''straw man'' is given to achieve this main objective.

The aqueous-based accelerator transmutation of waste (ATW) concept as proposed by Los Alamos National Laboratory uses a proton accelerator to produce a 1.6-GeV, 250-mA (similar to 400 MW) beam that is split four ways and directed to four D2O-cooled solid tungsten-lead composite targets. Each target in turn is centered in a heavy water moderated, highly multiplying, actinide (oxide)-slurry blanket. High thermal-neutron fluxes are produced that allow high transmutation reaction rates at low material (actinide, long-lived fission product) inventories. The target-blanket system for ATW resides at an interface separating two major systems that are crucial to the economic and technical success of the concept: (a) the high-energy (power-intensive) accelerator delivering 0.8 to 1.6 GeV protons to the high-Z spallation neutron source and (b) the chemical-plant equipment (CPE) that provides feedstock appropriate for efficient and effective transmutation. Parametric studies have been performed to assess the effects of the target-blanket on overall system performance with regard to neutron economy, chemical-processing efficiency, and thermal-hydraulic design options. Based on these parametric evaluations, an interim base-case aqueous-slurry ATW design was selected for more detailed analyses. This base-case target-blanket consists of an array of Zr-Nb pressure tubes placed in a heavy water moderator surrounding a heavy-water-cooled tungsten-lead target. Neutronics and thermal-hydraulic calculations focusing primarily on the blanket indicate that each of the four ATW target-blanket modules operating with a neutron multiplication k(eff) = 0.95 can transmute the actinide waste and the technetium and iodine waste from similar to 2.5 light water reactors (LWRs). In addition, by recovering and converting the fission heat, sufficient electricity can be produced both to operate the accelerator and to supply power to the grid for revenue generation; the full (400-MW beam) system would service similar to 10 LWRs, which at 835 MW(thermal)/LWR (1363 mol/yr actinide), a thermal-to-electric conversion efficiency of 0.30, and an overall ''wall-plug'' accelerator efficiency of 0.50 would allow about two-thirds of the 2500-MW(electric) (gross) power to be delivered to the grid. The neutronics-, thermal-hydraulics-, and accelerator-CPE-interface consideration, needed to ensure this performance, is examined for the aqueous-slurry ATW. These broad-based parametric studies have provided guidance to a preliminary conceptual engineering design of the aqueous-slurry ATW blanket concept.

The coating layers surrounding the fuel kernels consist of pyrolytic carbon layers and a silicon carbide (SIG) layer. These coating layers act as a pressure vessel that retains fission product gases. The structural integrity of this pressure vessel relies on the strength of the SiC layer. If the SiC fractures because of the internal pressure loading, then the particle fails. Results obtained from a series of crush tests on unirradiated fuel particles were used to estimate the strength of the SiC layer for internal pressure loading. The SIC strength for a particle was defined in terms of the maximum stress level in the SiC layer at which the particle failed. The transformations between the test results, which involve compressive crushing loads, and the internal pressure loadings experienced in NP-MHTGR reactor conditions were made utilizing the Weibull statistical theory. The test results were also used to estimate failure probabilities for fuel particles that are lacking an outer pyrolytic carbon layer (OPyC). The transformation from the crush test failure data to equivalent SIC strengths under an internal pressure load allowed for a direct comparison in strengths between fully coated particles and particles that lack the OPyC layer. In the latter case, the OPyC has typically been removed through a ''burn-back'' process. Results showed that strengths for fully coated particles are somewhat higher than for burned-back particles. Whether this is attributable to an actual loss of strength because of the burn-back process or is an artifact of the testing process is a subject for further study. Other effects on particle strength measured by making similar comparisons were particle compacting and particle flaws (large ''gold spots''). These generally did not have a significant effect on SiC strengths. Another finding from calculations performed was that application of a ''spread ring'' load rather than a concentrated ''point'' load in the crush tests was more representative of the internal pressure loading experienced in NP-MHTGR reactor conditions. Results of the failure probability calculations showed that the failure probability for a batch of burned-back fuel particles was governed by a weak ''tail'' group of particles, which constitute a small percentage of the total particle batch.

For test pins that undergo melting but remain intact, a technique is described that relates fuel thermal conductivity to peak pin power during the transient and a posttest measured melt radius. Conductivity estimates and their uncertainty are made for a database of four irradiated Integral Fast Reactor-type metal fuel pins of relatively low burnup (<3 at.%). In the assessment of results, averages and trends of measured fuel thermal conductivity are correlated to local burnup. Emphasis is placed on the changes of conductivity that take place with burnup-induced swelling and sodium logging. Measurements are used to validate simple empirically based analytical models that describe thermal conductivity of porous media and that are recommended for general thermal analyses of irradiated metallic fuel.

Any classifier system used to enhance the operator's capability to diagnose a safety-critical system like an NPP should classify a novel transient as ''don't-know'' if it is not contained within its accumulated knowledge base. In particular, the classifier needs some kind of proximity measure between the new data and its training set. Artificial neural networks have been proposed as NPP classifiers, the wrest popular ones being the multilayered perceptron (MLP) type. However, MLPs do not have a proximity measure, while learning vector quantization, probabilistic neural networks (PNNs), and some others do. This proximity measure may also serve as an explanation to the classifier's decision in the way that case-based-reasoning expert systems do. The capability of a PNN network as a classifier is demonstrated using simulator data for the three-loop 436-MW(electric) Westinghouse San Onofre unit 1 pressurized water reactor. A transient's classification history is used in an ''evidence accumulation'' technique to enhance a classifier's accuracy as well as its consistency.

Inertial as well as viscous effects are considered in the momentum equation. The mathematical model for energy transport was based on the hue-phase equation model, which does not employ local thermal equilibrium assumption between the fluid and the solid phases. The transport processes for two different types of boundary conditions are studied. The analysis teas performed in terms of nondimensional parameters that successfully cast together ad the pertinent influencing effects. Comparisons were made between our numerical findings and experimental results. Overall, the comparisons that were made for the constant wad heat flux boundary condition display good agreement.

Nighttime respiration was between 0.5 and 1.5 kg C ha(-1) h(-1), increasing with temperature. Net uptake of carbon during the day peaked at 3 kg C ha(-1) h(-1), and the daily net uptake over the experiment was 12 kg C ha(-1) day(-1). Photosynthesis dropped substantially at leaf-to-air vapor pressure deficit (VPD) greater than 7 mb, presumably as a result of stomatal closure. The response of ecosystem photosynthesis to incident PPFD was markedly non-linear, with an abrupt saturation at 600 mu mol m(-2) s(-1). This sharp saturation reflected the geometry of the spruce canopy (isolated conical crowns), the frequently overcast conditions, and an increase in VPD coincident with high radiation. The ecosystem light-use efficiency increased markedly during overcast periods as a result of a more even distribution of light across the forest surface. A mechanistic model of forest photosynthesis, parameterized with observations of leaf density and nitrogen content from a nearby stand, provided accurate predictions of forest photosynthesis. The observations and model results indicated that ecosystem carbon balance at the site is highly sensitive to temperature, and relatively insensitive to cloudiness.

These anomalies can be explained on the basis of growth analysis of whole plants. Some plants may fail to respond to enrichment because they are long-lived and have conservative growth responses or come from impoverished habitats. Apparent (but not real) acclimation to CO2 enrichment might be observed if only part of the growth curve over the life of a perennial is studied. The apparent increased efficiency of nitrogen use may merely be an increase in storage of nonstructural carbohydrate. A model analysis of these effects is presented. Discrepancies among species in relative responses of different plant parts are argued to be largely a function of where the plant typically stores nonstructural carbohydrates, which itself is a function of plant growth stage. Thus, a closer consideration of plant growth strategies and growth partitioning is needed to properly interpret results of CO2 enrichment studies.

Heating a toluene solution of 2 with 1 equiv of Cp*H (Cp* = C(5)Me(5)) leads to formation of the dimeric triflate-bridged complex Cp*[(Me(3)Si)(2)N]Th(mu 2-OSO2CF3)(3)Th[N(SiMe(3))(SiMe(2)Ch(2))]Cp* (4).

The starting complex for our NMR experiments, [Cp*Rh(H2O)(3)](OTf)(2), 1, was structurally characterized by single-crystal X-ray crystallography [130 K, Mo K alpha radiation, lambda = 0.710 73 Angstrom, a = 23.979(9) Angstrom, b = 9.726(4) Angstrom, c = 18.257(6) Angstrom, Z = 8, orthorhombic, space group Pna2(1), 3879 independent reflections, R = 0.0482, R(w) = 0.1062]. Both H-1 and C-13 NMR titration experiments of the starting complex, 1, were performed by dissolving 1 in H2O (D2O) and obtaining spectra from pH 2-14. From pH 2-5 only one Cp* signal(H-1 NMR, 1.57 ppm; C-13 NMR, 5.78 ppm) was observed, which was attributed to 1. As the pH of the solution with 1 was increased from 5 to 7, a dynamic and rapid equilibrium was observed to provide putative [Cp*Rh(mu-OH(H2O](2)(OTf)(2) 2, and [(Cp*Rh)(2)(mu-OH)(3)](OTf/OH), 3; unfortunately, only one H-1 or C-13 NMR signal for Cp*Rh at 1.50 (Cp*) or 5.41 ppm (C-CH3), respectively, was found for the latter two species, with broadening of the signals at pH 5.5-6, indicating that conversion from putative 2 to 3 was very fast on the NMR time scale. As the pH was further increased from 7 to 10, only the H-1 or C-13 NMR signal for 3 was observed at 1.50 or 5.41 ppm, respectively. In addition, starting the equilibrium from 3 (3 reversible arrow 1 via putative 2) within the pH range 14-2 provided similar results. The 2D NOESY NMR exchange phasing experiments at pH 5.8 and 11 showed correlations between the Cp* CH3 groups and the H2O or mu-OH groups attached to Rh and between both Cp* CH3 groups of the Cp*Rh aqua complexes, although separate signals for bulk H2O and mu-OH or H2O ligands bonded to Rh were not observed due to a rapid exchange process. A potentiometric titration study gave further evidence that the conversion of 1 double right arrow 3 via putative 2 occurs rapidly with only one pK(a) of 5.3 being observed, reaffirming the fact that the conversion of 1 double right arrow 3 via putative 2 was extremely fast. The pseudo-first-order rate of conversion of 1 double right arrow 3 at pH 5.8 was measured by an NMR spin population transfer technique to be k(1) = 7.18 s(-1) (1, 0.034 M; T-1 = 1.6 s), while k(-1), 3 double right arrow 1, was found to be 2.93 s(-1) (T-1 = 1.5 s). The equilibrium constant, K-eq, at pH 5.8 for 1 reversible arrow 3 was found to be 353. O-17 NMR studies again showed that H2O molecules bonded to Cp*Rh and those in the bulk solution are in very fast exchange (k > 8150 s(-1)).

In both the Pr- and Nd-based melt-quenched die-upset magnets we consistently observed a very thin Fe-rich amorphized intergranular phase at the boundaries, and this finding may have an impact on our understanding of the coercivity mechanism of these materials. Although the value of the method was demonstrated for transition metal-rare earth intermetallics, it may also be applied to grain-boundary studies in other materials.

This result is applied to particle motion in the quantized orbits of the old quantum theory, and it is found that the lapse in clock reading between a stationary clock and a dock that has completed an orbit of quantized motion is just an integral multiple of half the rest mass period. This result is proposed as an alternative way of stating the Bohr-Sommerfeld quantization conditions. It is proposed that this result for quantized semiclassical orbits may be indicative of the presence of an inherent relationship between the spatiotemporal characteristics of any quantized system and the characteristic periodicity associated with the rest mass of the particles involved.

An inflationary potential on moduli space can result if the scale of dynamical SUSY breaking in some sector of the theory is determined by a moduli dependent coupling. The magnitude of density fluctuations generated during inflation then depends on the scale of SUSY breaking in this sector. This can naturally be hierarchically smaller than the Planck scale in a dynamical model, giving small fluctuations without any fine tuning of parameters. It is also natural for SUSY to be restored at the minimum of the moduli potential, and to leave the universe with zero cosmological constant after inflation. Acceptable reheating can also be achieved in this scenario. RP THOMAS, S (reprint author), STANFORD UNIV,STANFORD LINEAR ACCELERATOR CTR,STANFORD,CA 94309, USA.

Our data are fit to a model consisting of a sum of Breit-Wigner amplitudes for the intermediate two-body resonant decay modes. We extract decay fractions and relative phases. These results are used to infer new branching ratios for D+ --> K(+)K(-)pi(+) inclusive as well as the phi pi(+) and ($) over bar K* (892) K-O(+) channels.

We emphasize the unique aspects of hadronic many-body systems containing nonzero strangeness and the opportunities that exist to exploit this physics. Our understanding of the elementary hyperon-nucleon interaction and its role in few-body systems is summarized. In particular, we examine the constraints that our knowledge of few-body systems place upon parameterizations of the realistic hyperon-nucleon force models. Also, issues involving the structure of p-shell hypernuclei as well as the weak decays of hypernuclei are summarized in some detail. Finally, the future prospects for strange-particle nuclear physics involving Lambda s, Sigma s, and Xi s at existing facilities are discussed. C1 UNIV HOUSTON,DEPT PHYS,HOUSTON,TX 77004.

One of the first differentially displayed products identified was shown to be ten-fold induced after start of GA treatment. The sequence of the clone shows complete amino acid identity with histone H3, and its increased mRNA level correlates with the onset of DNA synthesis. We also identified a gene whose expression pattern did not change over the course of treatment with GA and can be used as standard to correct for loading differences on northern blots.

The geometry of the nested magnetic flux surfaces is specified by a model that includes displacement, elongation and triangularity effects. The radial dependence in flux coordinates is described by a consistent set of trial functions which allows analytical calculation of the flux-surface averaged internal energy density of the plasma. Approximate solutions of the variational problem are obtained for arbitrary aspect-ratio tokamaks using a one-parameter optimization procedure.

All reciprocal lattice vectors (plane normals) of (110), (040), and (130) were found to populate in the film normal (thickness) direction, suggesting that more than one orientation process must be involved in the deformation. SAXS studies on the cold-rolled UHMWPP reveal an oriented lamellar structure with its long axis perpendicular to the rolled direction, however, the lamellae are somewhat tilted. Refractive index and tensile measurements were undertaken to determine the optical and mechanical anisotropy of the cold-rolled UHMWPP films. A similar study was undertaken of unidirectionally rolled conventional polypropylene (PP) for comparison. C1 UNIV AKRON,INST POLYMER ENGN,AKRON,OH 44325.

Rev. A49, 3664 (1994)] of elastic scattering of 81 keV gamma rays in the angular range from 60 degrees to 133 degrees has been extended to smaller and larger angles. Previously reported S matrix calculations of atomic Rayleigh scattering have been shown to require a subtraction of contributions from spurious resonances. Most of the experimental data are in agreement with the calculations. Calculations (MF + ASF) based on a combination of relativistic modified form factors (MF's) and angle independent anomalous scattering factors (ASF's) are found to be inadequate for an explanation of experimental cross-sections in the case of high Z elements at angles larger than about 120 degrees.

The well-founded reason for this is the common non-existence of equilibrium in polymeric materials. In the meantime, however, extrapolation methods and special polymerization and crystallization techniques have been developed to assess the equilibrium properties of polymers. The ATHAS data bank, for example, contains such equilibrium information on heat capacities from 0 to 1000 K, vibrational spectra, transition parameters, enthalpies, free enthalpies, and entropies for over 200 polymers and polymer-related materials. The availability of such data for polymers proved of great importance for the analysis of metastable states. With reference to the equilibrium limit, stability estimates can be made and detailed studies are possible of the superheating on melting and supercooling on crystallization. Comparisons of the vibrational heat capacities with measured data reveal conformational motion in polymers. A new mesophase, that of condis crystals, could be defined. A new glassy state, the rigid amorphous state, could be identified. For the first time, it became even possible to analyze drawn fibers using a multi-phase approach based on thermal and structural analyses.

We find that large deletions are common. The entire hprt gene (>44 kb) was missing in 19/39 Fe-induced mutants, while only 2/30 spontaneous mutants lost the entire hprt coding sequence. When the gene of interest (S1 locus = M1C1 gene) is located on a nonessential human chromosome 11, multilocus deletions of several million base pairs are observed frequently. The S1 mutation frequency is more than 50-fold greater than the frequency of hprt mutants in the same cells. Taken together, these results suggest that low-fluence exposures to Fe ions are often cytotoxic due to their ability to create multilocus deletions that may often include the loss of essential genes. In addition, the tumorigenic potential of these HZE heavy ions may be due to the high potential for loss of tumor suppressor genes. The relative insensitivity of the hprt locus to mutation is likely due to tight linkage to a gene that is required for viability. C1 COLORADO STATE UNIV,DEPT RADIOL HLTH SCI,FT COLLINS,CO 80523.

Which if any ''effects function'' best describes the relationship between field exposure and biological effect is uncertain at this time. Also, in a particular context such as construction of new transmission lines there are a variety of different technologies which might be used to reduce exposure. We describe and demonstrate a method by which exposure reduction supply curves (i.e., the cost of purchasing different amounts of exposure reduction given various mitigation options) can be estimated parametrically for different exposure conditions and effects functions, and we display illustrative results.

To quantify JUV in risk, Monte Carlo methods typically require nested sampling of JUV in distributed inputs, which is cumbersome and time-consuming. Two approximation methods proposed here allow simpler and more rapid analysis. The first consists of new upper-bound JUV estimators that involve only uncertainty or variability, not both, and so never require nested sampling to calculate. The second is a discrete-probability-calculus procedure that uses only the mean and one upper-tail mean for each input in order to estimate mean and upper-bound risk, which procedure is simpler and more intuitive than similar ones in use. Application of these methods is illustrated in an assessment of cancer risk from residential exposures to chloroform in Kanawah Valley, West Virginia. Because each of the multiple exposure pathways considered in this assessment had separate modeled sources of uncertainty and variability, the assessment illustrates a realistic case where a standard Monte Carlo approach to JUV analysis requires nested sampling. In the illustration, the first proposed method quantified JUV in cancer risk much more efficiently than corresponding nested Monte Carlo calculations. The second proposed method also nearly duplicated JUV-related and other estimates of risk obtained using Monte Carlo methods. Both methods were thus found adequate to obtain basic risk estimates accounting for JUV in a realistically complex risk assessment. These methods make routine JUV analysis more convenient and practical. RP BOGEN, KT (reprint author), LAWRENCE LIVERMORE NATL LAB,DIV HLTH & ECOL ASSESSMENT L453,7000 E AVE,LIVERMORE,CA 94550, USA.

Non-equilibrium phenomena, such as spectral and kinetic hole burning as well as plasma heating effects, are analysed using a quantum kinetic approach.

The disruption or loss of this BM occurs during normal development as well as in the disease state. To examine the importance of BM during mammary gland development in vivo, we generated transgenic mice that inappropriately express autoactivating isoforms of the matrix metalloproteinase stromelysin-1. The mammary glands from these mice are both functionally and morphologically altered throughout development. We have now documented a dramatic incidence of breast tumors in. several independent lines of these mice. These data suggest that overexpression of stromelysin-1 and disruption of the BM may be a key step in the multi-step process of breast cancer C1 UNIV CALIF SAN FRANCISCO,RADIOBIOL & ENVIRONM HLTH LAB,SAN FRANCISCO,CA 94143.

The mechanisms by which extracellular matrix affects differentiation, as well as the nature of extracellular matrix constituents which have major impacts on mammary gland function, have only now begun to be dissected. The intricate variety of extracellular matrix-mediated events and the remarkable degree of plasticity of extracellular matrix structure and composition at virtually all times during ontogeny, make such studies difficult. Similarly, during carcinogenesis, the extracellular matrix undergoes gross alterations, the consequences of which are not yet precisely understood Nevertheless, an increasing amount of data suggests that the extracellular matrix and extracellular matrix-receptors might participate in the control of most, if not all, of the successive stages of breast tumors, from appearance to progression and metastasis.

To study the evolution of human breast cancer; a functionally relevant cell culture model is required which recognizes the complexity of the mammary gland's microenvironment. The development of an appropriate breast epithelial cancer cell model will be dep ndent on the ability to recreate the 'normal' and 'neoplastic' tissue microenvironment in culture. Towards this goal, a 3-dimensional extracellular matrix (ECM) essay, employing a reconstituted basement membrane, has been developed which allows for the rapid and accurate discrimination of normal and neoplastic cells when cultured. To investigate stromal/epithelial cell interactions, we have developed a tumor environment assay which essentially mirrors the tumor microenvironment histologically. The use of a novel, near diploid, human breast epithelial cell line, HMT-3522 which has transformed spontaneously with passage in culture, together with these 3-dimensional culture assays is expected to provide meaningful markers of initiation and progression.

Particular emphasis is placed on the development of scalable algorithms for multiple instruction multiple data (MIMD) distributed memory concurrent computers. A brief description of the EISPACK, LINPACK, and LAPACK libraries is given, followed by an outline of ScaLAPACK, which is a distributed memory version of LAPACK currently under development. The importance of block-partitioned algorithms in reducing the frequency of data movement between different levels of hierarchical memory is stressed. The use of such algorithms helps reduce the message startup costs on distributed memory concurrent computers. Other key ideas in our approach are the use of distributed versions of the Level 2 and Level 3 basic linear algebra subprograms (BLAS) as computational building blocks, and the use of basic linear algebra communication subprograms (BLACS) as communication building blocks. Together the distributed BLAS and the BLACS can be used to construct higher-level algorithms, and hide many details of the parallelism from the application developer. The block-cyclic data distribution is described and adopted as a good way of distributing block-partitioned matrices. Block-partitioned versions of the Cholesky and LU factorizations are presented, and optimization issues associated with the implementation of the LU factorization algorithm on distributed memory concurrent computers are discussed, together with its performance on the Intel Delta system. Finally, approaches to the design of library interfaces are reviewed. C1 OAK RIDGE NATL LAB,MATH SCI SECT,OAK RIDGE,TN 37831.

The substitution of Pr for Nd leads to a reduction in the overall MR, and an increase of the MR-peak temperature. We investigate the possibility that the large negative MR originates from the formation of localized magnetic polarons. C1 UNIV CALIF BERKELEY,LAWRENCE BERKELEY LAB,DIV MAT SCI,BERKELEY,CA 94720.

The present study examines the contributions of sexual variation in energy allocation and timing of reproduction to the growth and size of southwestern earless lizards. Growth curves were developed for snout-vent length (SVL), weight, and the ratio of these measures to examine sexual differences in size at emergence from hibernation, asymptotic size, and characteristic growth rates. The energy content of an average clutch of eggs was determined, converted to the equivalent energy content in body tissues, and used to determine the expected increase in size of females if the energy was used for growth instead of reproduction. Parameter estimates from growth curves for all measures of size differed only for asymptotic value. The patterns indicate female growth slows at an earlier age than males, probably because they must devote energy to reproduction earlier in life. The energy content in eggs can account for 63% to 90% of the difference in size depending on the hypothetical age at which females can divert stored energy to reproduction. These results suggest that hypotheses of sexual dimorphism that incorporate the cost of and timing of reproductive investments are viable alternatives to those employing sexual selection.

The analogs are C-13(6) in which the central six carbon atoms are substituted with C-13; C-13(2) in which only the two central atoms are substituted and S-34(8) and d(8) in which all of the sulphur or all of the hydrogen atoms are substituted; respectively. The frequencies and frequency shifts of the Raman features and the infrared powder absorption features are measured. The polarized infrared reflectivity of a single crystal, and the intensities of the Raman features, help in assigning symmetries to certain resonances. By comparing these shifts to those calculated using a realistic valence force model the assigment of most of the in-plane fundamental intermolecular vibrational modes, and a few of the out-of-plane ethylene modes is achieved. The force constants are refined to produce excellent overall agreement between the measured and calculated frequencies and isotope shifts. C1 SIMON FRASER UNIV,DEPT PHYS,BURNABY,BC V5A 1S6,CANADA.

When these multidomained HTSS are subjected to thermal shock, however, the I(c) is found to be degraded. In order to ascertain the cause of this decrease, microscopic studies have been performed. The results indicate that the decrease in I(c) can be linked to the generation and propagation of microcracks between the a-b plane grain boundaries. Hot isostatic pressing (HIPING) has been found to be effective in eliminating this degradation, and the I(c) of HIPED HTS samples is no longer sensitive to thermal cycling. Microstructural observations revealed that HIPING resulted in a reduction in the amount and the size of microcracks as compared with thermally cycled HTSS. Moreover, large macrocracks are found to be bridged by reaction products. The healing of microcracks and the strengthening of a-b plane grain boundaries as well as the transformation of macrocracks are believed to be responsible for the improved superconducting and mechanical stability of the HIPED HTSS.

The chemisorption is stronger and involves larger molecular distortions than on palladium and rhodium surfaces in agreement with experiment. On the hollow site, the benzene molecule undergoes a Kekule distortion. On the bridge site found experimentally (with or without coadsorbed CO), the benzene molecule undergoes a local C-2u distortion with long and short C-C bonds also in qualitative agreement with experiment. The favored azimuthal orientation of pure benzene coincides with that found experimentally only in the presence of CO. According to calculations, CO adsorption is found to weaken the benzene adsorption and reduce its metal-induced distortions but preserved the same orientation.

The formation of Au-Mo bonds induces shifts toward higher binding energy (0.3-0.7 eV) in the core levels and valence d band of gold. This is accompanied by an important redistribution of charge, in which Au loses 5d electrons and gains (6s,6p) electrons. The positive binding-energy shifts in the Au 4f levels and 5d band reflect the effects of a Mo-induced reduction in the Au 5d electron population.

To determine whether the concentration of dopamine normally present in the synaptic cleft can compete with [C-11]cocaine for transporter binding sites, we conducted baboon PET studies with drugs (sodium 4-hydroxybutyrate, four studies, 200 mg/kg; gamma-vinylGABA, three studies, 300 mg/kg; and citalopram, three studies, 2 mg/kg) expected to decrease synaptic dopamine. Each study involved two [C-11]cocaine injections and PET scans separated by 2-4 h, with drug administration after the first injection, and without movement of the subject between scans. Time-activity data from striatum and from cerebellum were used with the arterial plasma input function to determine graphically by Logan plotting [C-11]cocaine distribution volumes for the brain regions. Specific binding of [C-11]cocaine to DAT in striatum was calculated as the distribution volume ratio (DVR) for striatum and cerebellum. In nine of the ten studies drug treatment produced a small increase in DVR (range, 1-11%), and in seven of these studies the increase was greater than or equal to 7%. The mean increase was 6.2 +/- 4.1%. The reproducibility of the DVR measure was assessed by comparing [C-11]cocaine studies conducted without pharmacological treatments using individual baboons on separate days, and thus involving possible repositioning errors, as well as long-term changes in the state of the striatal dopamine system. For four individual baboons with three or four studies per animal the mean (+/-s.d.) values of DVR were 1.73 +/- 0.03, 1.39 +/- 0.03, 1.53 +/- 0.06, and 1.54 +/- 0.12. The maximum differences between baseline DVRs, expressed as percentage of the lowest value, were 5%, 5%, 9%, and 20%. For two other baboons with two studies each, the between study differences were 1% and 9%. Thus within-subject variability was quite low, even with repositioning. The results suggest that [C-11]cocaine binding to the DAT is sensitive to pharmacological alterations in the concentration of synaptic dopamine. However, the sensitivity of [C-11]cocaine to dopamine-depletion is less than that of the D2 receptor radioligand [C-11]raclopride, in agreement with literature in vitro binding studies, and is unlikely to be a serious issue in PET evaluations of DAT density.

Mathew TI The interaction of short-chain model lubricants with the surfaces of hydrogenated amorphous carbon films SO TRIBOLOGY LETTERS LA English DT Article DE amorphous carbon; model lubricants; temperature programmed desorption AB The adsorption of water and small model perfluorinated lubricants on hydrogenated amorphous carbon (a:C-H) films of varying hydrogen content was investigated using thermal desorption spectroscopy (TDS). Hydrogen content of the carbon films was measured by Rutherford back scattering (RBS) and elastic recoil spectroscopy (ERS) and correlated to changes in surface free energies measured by contact angle analysis. Hydrogenated carbon films exhibiting the highest surface free energy provided a greater attractive interaction for the model lubricants. All model lubricant species studied - water (D(2)O), perfluorodiethyl ether (CF(3)CF(2)OCF(2)CF(3)), perfluoropentane (CF(3)(CF(2))(3)CF(3)), perfluorooctane (CF(3)(CF(2))(6)CF(3)), 2,2,2-trifluoroethanol (CF(3)CH(2)OH), and 1,1,7-H-perfluoroheptanol (CF(2)H(CF(2))(5)CH(2)OH)-reversibly adsorbed to the carbon surface with little chemical reaction. Increases in desorption energies with increasing chain length were observed among the adsorbates and are ascribed to increasing van der Waals interactions. Incorporation of alcoholic end groups provided an avenue of hydrogen bonding to the surface and produced an similar to 20 kJ/mol increase in desorption energy relative to a perfluorinated alkane of the same chain length. Ether linkages within the model lubricant provide little increase in desorption energy as fluorine substituents effectively screen the oxygen. Together these findings implicate a predominantly physisorbed state for perfluorinated lubricants on hydrogenated carbon surfaces.

The portable RO system used in our research group can process 150-2001 of water per hour with 90% recovery of organic carbon without exposing DOM to harsh chemical reagents. The system has been tested in blackwater streams, low-DOM streams, and in ground waters from very deep aquifers (>1000 m). This paper discusses (1) percent recovery of organic carbon from a variety of surface and ground waters, (2) laboratory and modeling studies of the pH dependence of the recovery of low molecular weight organic acids from dilute solutions, and (3) operational factors that potentially affect the performance of the RO system in field experiments.

The geometries of the two transition states with tau(SSSS) = 0 degrees and 180 degrees can be explained by hyperconjugation between the lone pairs at the terminal sulfur atoms and the sigma(*) molecular orbital of the central bond.

LUND MONTE-CARLO; CHARGE ASYMMETRY; HADRONIC DECAYS; Z0; ANNIHILATION; EVENTS; JETS AB A measurement of the strange quark forward-backward asymmetry at the Z(0) peak was performed using 718,000 multihadronic Z(0) decays collected by the DELPHI detector at LEP in 1992. The s-quark was tagged by the presence of high momentum charged kaons identified by the Ring Imaging Cherenkov detector and by Lambda(0)'s decaying into p pi(-). The s-quark purity obtained was estimated for the two hadrons to be 43%. The average s-quark asymmetry was found to be 0.131 +/- 0.035 (stat.) +/- 0.013 (syst.). The forward-backward asymmetry was measured for unresolved d- and s-quarks, tagged by the detection of a high energy neutron or neutral kaon in the Hadron Calorimeter. The combined d- and s-quark purity was 69% and their asymmetry was found to be 0.112 +/- 0.031 (stat.) +/- 0.054 (syst.). C1 IOWA STATE UNIV SCI & TECHNOL, AMES LAB, AMES, IA 50011 USA.

NEUTRAL HIGGS BOSONS IN 2-DOUBLET MODELS SO ZEITSCHRIFT FUR PHYSIK C-PARTICLES AND FIELDS LA English DT Article ID Z0 DECAYS; MASS AB A search for pair production of neutral heavy Higgs bosons decaying into has been carried out in a study of hadronic decays of the Z boson into four jet final states using data taken by DELPHI in 1991 and 1992. The two production mechanisms present in the two Higgs doublets scheme, bremsstrahlung production of hZ* and associated production of hA, may lead to four beauty jets well recognizable using the precise microvertex detector measurements. No evidence for a signal was found, leading to limits on BR(Z -->, hA --> 4b) from 3.5 to 5.5 x 10(-4) at 95% confidence level, depending on the mass of the ligthest Higgs. When combined with the results of the recent DELPHI standard Higgs search, this result allows the kinematical limit to be reached for the masses of h and A in the minimal supersymmetric extension of the Standard Model (MSSM) scheme. It also allows the tan beta less than or equal to 1 domain to be explored, and a region above the kinematic limit for direct hA production is constrained by considering virtual hA production.

SCHMIDKE, WB TI JET PRODUCTION IN HIGH Q(2) DEEP-INELASTIC EP SCATTERING AT HERA SO ZEITSCHRIFT FUR PHYSIK C-PARTICLES AND FIELDS LA English DT Article ID PARTON DISTRIBUTIONS; PROTON SCATTERING; DEPENDENCE; RATES AB Two-jet production in deep-inelastic electron-proton scattering has been studied for 160 < Q(2) < 1280 GeV2 0.01 < x < 0.1 and 0.04 < y < 0.95 with the ZEUS detector at HERA. The kinematic properties of the jets and the jet production rates are presented. The partonic scaling variables of the two-jet system and the rate of two-jet production are compared to perturbative next-to-leading order QCD calculations. C1 UNIV BOLOGNA, BOLOGNA, ITALY.

Charged particle production has been measured in Deep Inelastic Scattering (DIS) events using the ZEUS detector over a large range of Q(2) from 10 to 1280 GeV2 The evolution with Q of the charged multiplicity and scaled momentum has been investigated in the current fragmentation region of the Breit frame. The data are used to study QCD coherence effects in DIS and are compared with corresponding e(+)e(-) data in order to test the universality of quark fragmentation. C1 UNIV BOLOGNA, BOLOGNA, ITALY.

C-PARTICLES AND FIELDS LA English DT Article ID LUND MONTE-CARLO; LEP-SLC ENERGIES; RADIATIVE-CORRECTIONS; BHABHA SCATTERING; JET FRAGMENTATION; Z-RESONANCE; POLARIZATION; PHYSICS; SIMULATION; PARAMETERS AB A sample of Z(0) --> tau(+)tau(-) events observed in the DELPHI detector at LEP in 1991 and 1992 is analysed to measure the tau polarisation in the exclusive decay channels e nu ($) over bar nu, mu nu ($) over bar nu, pi nu, rho nu and a(l) nu. The tau polarisation is also measured with an inclusive hadronic analysis which benefits from a higher efficiency and a better systematic precision than the use of the exclusive decay modes. The results have been combined with those published on the 1990 data. A measurement of the tau polarisation as a function of production angle yields the values for the mean tau polarisation [P-tau] = -0.148 +/- 0.022 and for the Z(0) polarisation P-z = -0.136 +/- 0.027. These results are used to determine the ratio of vector to axial-vector effective couplings for taus ($) over bar upsilon(tau)/($) over bar a(tau) = 0.074 +/- 0.011 and for electrons ($) over bar upsilon(e)/($) over bar a(e) = 0.068 +/- 0.014, compatible with e-tau universality. With the assumption of lepton universality, the ratio of vector to axial-vector effective couplings for leptons ($) over bar upsilon(l)/($) over bar a(l) = 0.072 +/- 0.008 is obtained, implying a value of the effective weak mixing angle sin(2) theta(eff)(lept) = 0.2320 +/- 0.0021.

DT Article ID CENTRAL TRACKING DETECTOR; ZEUS BARREL CALORIMETER; MONTE-CARLO; HADRONIC PROCESSES; COLLIDER ENERGIES; PHOTON; DISSOCIATION; CONSTRUCTION; DESIGN; ORDER AB Inclusive transverse momentum spectra of charged particles in photoproduction events in the laboratory pseudorapidity range -1.2 < eta < 1.4 have been measured up to P-T = 8 GeV using the ZEUS detector. Diffractive and non-diffractive reactions have been selected with an average gamma p centre of mass (c.m.) energy of (W) = 180 GeV. For diffractive reactions, the p(T) spectra of the photon dissociation events have been measured in two intervals of the dissociated photon mass with mean values (M(X)) = 5 GeV and 10 GeV. The inclusive transverse momentum spectra fall exponentially in the low p(T) region. The non-diffractive data p show a pronounced high p(T) tail departing from the exponential shape. The p(T) distributions are compared to lower energy photoproduction data and to hadron-hadron collisions at a similar c.m. energy. The data are also compared to the results of a next-to-leading order QCD calculation. C1 UNIV BOLOGNA, I-40126 BOLOGNA, ITALY. IST NAZL FIS NUCL, I-40126 BOLOGNA, ITALY.

Ultrasonic vacuum extraction provides near-quantitative gas yields within 30 min, and allows on-line preparation of carbon dioxide, nitrogen and oxygen for isotopic analyses. This method eliminates uncertainties involved in correcting headspace gas analyses for solubilities and liquid-vapor isotopic fractionation. In addition to developmental data, some field results are given to demonstrate the applicability of the method to geochemical studies.

In this early work, electrostatic comb-drive actuation is used to demonstrate the microengine. However, the basic gear/link element of the microengine can be driven by any suitably forceful linear actuators. This device has direct application as a drive and power source for micromachined mechanisms such as optical switches, electrical switches, micropositioners, or any other micro-sized device requiring mechanical power. This is the first device of its kind that is directly linked to an output gear and converts linear motion from comb-drive actuators to rotational motion. The microengine provides output in the form of a continuously rotating output gear (approximate to 50 mu m in diameter) that is capable of delivering torque to a micromechanism. The microengine can be operated at varying speeds and its motion can be reversed. Processing considerations address the elimination of natural interferences that arise when conformally deposited polysilicon films form the links, joints, and gears that comprise the microengine. The resultant device is completely batch fabricated without the need for piece-part assembly. RP GARCIA, EJ (reprint author), SANDIA NATL LABS,ALBUQUERQUE,NM 87185, USA.

Many of the Big Bang Nucleosynthesis reactions involve unstable nuclei. Hence, there is a tight relationship between the subject of this conference and cosmology. The prime role of unstable nuclei in cosmology is related to lithium synthesis and the lack of cosmological synthesis of Be and B. These nuclei will thus be focused upon. Nucleosynthesis involves comparing calculated abundances with observed abundances. In general abundance determinations are dominated by systematic rather than statistical errors, and work on bounding systematics is crucial. The quark-hadron inspired inhomogeneous calculations now unanimously agree that only relatively small variations in Omega(b) are possible vis-a-vis the homogeneous model; hence, the robustness of Omega(b) similar to 0.05 is now apparent. (These calculations depend critically on unstable nuclei.) The above argues that the bulk of the baryons in the universe are not producing visible light. A comparison with the ROSAT cluster data is also shown to be consistent with the standard BBN model. Omega(b) similar to 1 seems to be definitely excluded, so, if Omega(TOTAL) = 1, as some recent observations may hint, then non-baryonic dark matter is required. The implications of the recently reported halo microlensing events are discussed. In summary, it is argued that the physics of unstable nuclei affects the fundamental dark matter argument.

These crack-like instabilities are identified as the sources of dislocation nucleation and multiplication in films of high misfit. This link between morphological instability and dislocation nucleation provides a method for studying the basic micromechanisms that determine the strength and mechanical properties of materials.

This CoA-dependent transacylase did not require ATP or metal ions for activity making it unlikely that either acyl-CoA-synthetase or a Ca2+-dependent phospholipase A(2) were involved in the generation of [H-3]lyso-PAF. Albumin, in addition to CoA, was required to demonstrate the formation of [H-3]lyso-PAF from 1-[H-3]alkyl-2-acyl-sn-glyco-3-phosphocholine. It appeared that a major function of albumin in the incubations was to complex the [H-3]lyso-PAF formed, thus removing this end-product from the reaction. (C) 1995 Academic Press, Inc.

Analyte solutions were prepared from acetylcholine chloride, choline chloride, and methylphenylpyridinium (MPP(+)) iodide. Tandem mass spectrometry (MS/MS) was used to distinguish secondary ions characteristic of the analyte from secondary ions characteristic of the tissue itself. Effects of primary ion damage appear similar regardless of substrate. Samples of choline chloride deposited on a gold substrate are exceptional; secondary ion emission from such samples appeared unaffected by primary ion dose. Emission of acetylcholine secondary ions was found to decay with a rate independent of primary ion dose, but dependent on the substrate. These results show that the distribution of organic compounds can be mapped from biologic tissue under conditions of static SIMS, but matrix effects and chemical noise must be considered.

Certain very long-lived radioisotopes of very low natural abundances can be used to trace metabolism at environmental dose levels (greater than or equal to z mol in mg samples). C-14 in particular can be employed to label a myriad of compounds. Competing technologies typically require super environmental doses that can perturb the system under investigation, followed by uncertain extrapolation to the low dose regime. Ca-41 and Al-26 are also used as elemental tracers. Given the sensitivity of the accelerator method, care must be taken to avoid contamination of the mass spectrometer and the apparatus employed in prior sample handling including chemical separation. This infant held comprises the efforts of a dozen accelerator laboratories. The Center for Accelerator Mass Spectrometry has been particularly active. In addition to collaborating with groups further afield, we are researching the kinematics and binding of genotoxins in-house, and we support innovative uses of our capability in the disciplines of chemistry, pharmacology, nutrition and physiology within the University of California. The field can be expected to grow further given the numerous potential applications and the efforts of several groups and companies to integrate more the accelerator technology into biomedical research programs; the development of miniaturized accelerator systems and ion sources capable of interfacing to conventional HPLC and GMC, etc. apparatus for complementary chemical analysis is anticipated for biomedical laboratories.

Rate coefficients for electronic quenching of OH A(2) Sigma(+)(v' = 0) by the same set of collision partners are also reported. The measurements were performed at high temperatures (1900 and 2300 K) behind reproducible shock waves. The cross sections for quenching in v' = 1 were observed to be quite similar to the values found for quenching in v' = 0. For all of the species studied, the cross sections were found to be independent of temperature from 1900 to 2300 K. However, all of the high-temperature cross sections were found to be smaller than the previously reported values for quenching and vibrational energy transfer at 300 K. The decrease in the cross sections with temperature was observed to be more pronounced for vibrational energy transfer than for electronic quenching.

Experiments were performed with varying [CF2Cl2](0) in Kr diluent, over the temperature range 1446-2667 K, at three post-shock densities, 3.2, 2.2, and 1.2 x 10(18) cm(-3). This is the first thermal rate study for CF2Cl2 (+M) --> CF2Cl + Cl(+M). At 100% dissociation, the Cl atom yield, [Cl](infinity)/[CF2Cl2](0), is 2.02 +/- 0.13, confirming that C-Cl bond fission is the dominant dissociation pathway for both the parent CF2Cl2 molecule and the product CF2Cl radical, CF2Cl(+M) --> CF2 + Cl (+M). Molecular elimination to give CF2 + Cl-2 does not occur. The data can be represented in second order with the Arrhenius expression k(d) = (1.34 +/- 0.57) x 10(-7) exp(-31663 +/- 714 K/T) cm(3) molecule(-1) s(-1) (+/-34% error at the one standard deviation level) for 1446 less than or equal to T less than or equal to 2090 K. RRKM calculations have been applied to this reaction, and the temperature and pressure dependences of the rate constants can be characterized with threshold energy, E(0) = 85 +/- 1 kcal mol(-1), and energy transfer parameter, [Delta E(down)] = 1050 +/- 150 cm(-1). This threshold energy implies Delta(f)H(0 CF2Cl)(0) = -60.1 +/- 1 kcal mol(-1) acid a threshold energy for CF2Cl dissociation of E(0) = 49.1 +/- 1 kcal mol(-1). This low band strength in CF2Cl is consistent with the observed fast dissociation to produce the second Cl atom. C1 ARGONNE NATL LAB,DIV CHEM,ARGONNE,IL 60439.

XPS shows that the C-I bond of CF3I dissociates below 200 K to form CF3(ad) and I(ad); the subsequent reactions of CF3 are best viewed as being regulated by the availability of surface sites. CF3(ad) dissociates to CF2(ad) below 200 K. Further CF3 dissociation, some of which is activated by H(ad), occurs between 200 and 400 K until all available sites are filled. Desorption of the remaining CF3, peaking at 705 K, once again opens surface sites for decomposition. This is followed by recombination of the products to form CF3(g). No evidence for CF(ad) is ever observed. Hydrogen coadsorption studies explain interesting features associated with fluorine evolution. HREELS and ESDIAD results indicate that CF3 adopts a tilted configuration on Ru(001). C1 IOWA STATE UNIV SCI & TECHNOL,DEPT CHEM,AMES,IA 50011. IOWA STATE UNIV SCI & TECHNOL,AMES LAB,AMES,IA 50011.

The covalent linkage between the donor and acceptor constrains the distance and geometric relationship between them. The ability of the experiment to determine the nature of a particular physical phenomenon through separable polarization characteristics of the diffracted signal is used to analyze photophysical and photochemical processes in these molecules. This is achieved for cases in which the observed physical processes have overlapping spectral contributions, a situation where linear dichroism experiments are very difficult to interpret. Careful analysis of the absorption grating data allows us to determine rotational anisotropy values for the molecules in solution, two-photon absorption-state symmetries, and the relative orientation of the donor and acceptor in the Zn DMPPH-PI molecule. These results demonstrate complete separation of the contributions to the time dependent diffracted signal from the two radical ion pair products formed in the electron transfer reaction.

The pH behavior of these DNA intercalators' steady-state absorption and fluorescence spectra has also been investigated. While the excited-state pK(a)* for removal of a proton from the singly protonated species is close to the ground-state pK(a) in the parent molecule 9-aminoacridine, the presence of the carboxamide substituent renders pK(a)* much lower than pK(a) for the corresponding deprotonation in the present compounds. This fact, along with the presence of an additional deprotonation site at the distal N atom of the side chain, endows these molecules with complex pH dependence in their excited-state kinetics. Triexponential model functions are generally required to fit the experimental fluorescence decays, The pH dependence of the component lifetimes and preexponential factors can be simulated with a kinetic model for sequential deprotonations involving four aminoacridine species in both the ground and fluorescing states. These results provide a baseline study for comparisons with these intercalators' excited-state kinetics in DNA. C1 IOWA STATE UNIV SCI & TECHNOL,US DOE,DEPT CHEM,AMES,IA 50011.

A lowering in the energy surface of several MeV caused by octupole deformation, is found for many nuclides in the vicinity of W-176 at very large values of the elongation and necking. Octupole softness of the known extended minima is found to be quite similar in most instances. C1 UNIV AUTONOMA MADRID,DEPT FIS TEOR CXI,E-28049 MADRID,SPAIN.

We extract the nuclear transparency T(A, Q(2)), a measure of the average probability that the struck proton escapes from the nucleus A without interaction. Several calculations predict a significant increase in T with momentum transfer, a phenomenon known as Color Transparency. Within the measurement uncertainty, no increase is seen for any of the nuclei studied. C1 CALTECH,PASADENA,CA 91125. LAWRENCE LIVERMORE NATL LAB,LIVERMORE,CA 94550. AMERICAN UNIV,WASHINGTON,DC 20016.

The data exhibit an enhanced pion yield at low, p(t) compared to what is expected for a purely thermal spectral shape. This enhancement is used to determine the Delta resonance abundance at freeze-out. The results are consistent with a direct measurement of the Delta resonance yield by reconstruction of proton-pion pairs and imply a temperature of the system at freeze-out close to 140 MeV.

We show that the logarithmic integral of the spin-dependent photoabsorption cross section integral(nu th)(infinity) d nu/nu Delta sigma(Born)(nu) vanishes for any 2 --> 2 process gamma a bc in the classical, tree-graph approximation in the Standard Model, supersymmetric gauge theories, and other quantum field theories where the Drell-Hearn-Gerasimov sum rule is valid. Here nu = p . q/M and Delta sigma(nu) = sigma p(nu) - sigma(A)(nu) is the difference between the photoabsorption cross section for parallel and antiparallel photon and target helicities. Tests of the sum rule for the reactions gamma e --> W nu and gamma gamma --> W+W- can provide new tests of the canonical magnetic and quadrupole couplings of the Standard Model. We also extend the sum rule to certain virtual photon processes. C1 UNIV TECN FEDERICO SANTA MARIA, VALPARAISO, CHILE.

The observed relative energy sharing between the neutrino and the charged lepton is found to be well described with a W-+/- polarization obtained from a free b-quark decay model with a (V-A)x(V-A) decay structure. The alternative of a (V+A) x(V-A) decay structure is excluded with a significance of more than 6 standard deviations. The possibility that hadronic corrections to the b-hadron decay destroy any W-+/- polarization is disfavored by more than 3 standard deviations.

A BIOMIMETIC APPROACH TO SELECTIVE METAL-ION REMOVAL AND RECOVERY FROM AQUEOUS-SOLUTION WITH POLYMER-SUPPORTED SULFONATED CATECHOL AND LINEAR CATECHOL AMIDE LIGANDS SO INORGANIC CHEMISTRY LA English DT Article ID ENTEROBACTIN; ANALOGS AB The design of organic Ligands to selectively remove and recover metal ions from aqueous solution is a new and important area of environmental inorganic chemistry. One approach to designing organic ligands for these purposes is to use biological systems as examples for selective metal ion complexation. Thus, we report on our results on the synthesis of several biomimetically important polymer-supported, sulfonated catechol (PS-CATS), sulfonated bis(catechol) linear amide (PS-2-6-LICAMS), and sulfonated 3,3-linear tris(catechol) amide (PS-3,3-LICAMS) ligands that are chemically bonded to modified 6% cross-linked macroporous polystyrene-divinylbenzene beads (PS-DVB) for selective removal and recovery of environmentally and economically important metal ions from aqueous solution, as a function of pH. The Fe3+ ion selectivity was dramatically shown for PS-CATS, PS-2-6-LICAMS and PS-3,3-LICAMS polymer beads in competition with a similar concentration of Cu2+, Zn2+, Mn2+, Ni2+, Mg2+, Al3+, and Cr3+ ions at pH 1-3, while metal ion selectivity could be changed at higher pH values in the absence of Fe3+ (for example, Hg2+ at pH 3). Rates of removal and recovery of the Fe3+ ion with the PS-CATS, PS-2-6-LICAMS and PS-3,3-LICAMS polymer beads were also studied as well as relative equilibrium selectivity coefficient (K-m) values for all metal competition studies. The chelate effect for the octahedrally predisposed PS-3,3-LICAMS polymer pendant ligand, as shown for the homogeneous ligand, appears to be the reason that this polymer pendant ligand has a more pronounced selectivity for Fe3+ ion in comparison to the PS-CATS polymer beads, while the square planar predisposed PS-2-6-LICAMS series of polymer pendant ligands were more selective to divalent metal ions, CU2+, Zn2+, Mn2+, Ni2+, and Mg2+, than either PS-CATS or PS-3,3-LICAMS, although Fe3+ ion still dominated in competition with other divalent and trivalent metal ions. It is interesting to note that changing the cavity size from two CH2 groups to six CH2 groups in the PS-2-6-LICAMS polymer pendant ligand series did not affect the order of metal ion selectivity.

We were able to obtain a single-crystal X-ray analysis of a derivative of 1, the hemimethoxy ligand, 5-LICAM(OCH3)(2), 2, where partial demethylation of the fully methylated derivative of 1 was serendipitiously obtained in the presence of a deficiency of BBr3. The X-ray structure showed why we retained the methoxy group, during the partial demethylation reaction, in each catechol amide ring by the fact that a selective intramolecular hydrogen bond occurs between the one demethylated OH group in each catechol ring and the amide carbonyl in the adjacent position (C=O---HO, 1.67 Angstrom). Reaction of 1 with a Ni2+ salt provided the first structurally characterized square planar, linear bis-catechol amide, dianionic metal complex, with cesium as the counterion, Cs-2[5-LICAM-Ni]. 3DMF, 3, (Ni-O, 1.87 Angstrom, O-Ni-O, 87.9-92.5 degrees). It is also interesting to note that one of the cesium atoms was cis-bonded to the catechol oxygens in each ring (O2---Csl, O6-Csl=3.23 Angstrom, 3.03 Angstrom) and to the carbonyl oxygen of one of the three DMF solvent molecules (Csl-O=C, 3.13 Angstrom), while the other cesium atom was bonded to all three carbonyl oxygens of the DMF molecules in the structure (Cs2-O7, O8=3.13, 3.12 Angstrom). A Co2+ analogue of 3, Cs-2[5-LICAM-Co]. DMF, 4, provided a similar structure as ascertained by FT-IR, FAB/MS, and elemental analysis. In order to test the utilization of 1 in removing Ni2+ from aqueous solution for environmental inorganic applications, we synthesized the polymer pendant ligand version, PS-5-LICAM, bonded to modified 6% macroporous divinylbenzene-polystyrene beads (0.55 mmol/g), with an important modification of a sulfonate group on the catechol ring, PS-5-LICAMS IS, to impart hydrophilicity to the Ligand site. Indeed, we found that the PS-5-LICAMS ligand removed 0.35 mmol of Ni/g of polymer beads from aqueous solution at pH 2.5, but unfortunately, was not selective to Ni2+ in competition with other divalent metal ions. An in depth discussion of the X-ray structure of ligand 2 and that of the Ni complex, 3, will be presented. C1 UNIV CALIF BERKELEY,LAWRENCE BERKELEY LAB,BERKELEY,CA 94720.
