FN Thomson Reuters Web of Science™ VR 1.0 PT J AU WERLEY, KA AF WERLEY, KA TI A MEAN-FIELD DESCRIPTION OF REVERSED-FIELD PINCH - EQUILIBRIUM, DYNAMO, PLASMA-HEATING AND CONFINEMENT SO NUCLEAR FUSION LA English DT Article AB Three simple physics constraints are applied to describe the reversed field pinch (RFP) in a mean field sense. These constraints are: (a) a steady state equilibrium, (b) a negative radial pressure gradient, and (c) a net volumetric source of mean field magnetic energy that is always locally negative. Using these constraints, realistic RFP equilibria are calculated, plasma heating profiles are determined, and the role of the dynamo in rearranging profiles can be described by a mean field one dimensional picture. The RFP exists in a near minimum energy state characterized by a mu profile (where mu = mu(o)aJ . B/B-2) that decreases to a small value at the plasma edge. The resulting RFP confinement picture has three regions: a poorly confined plasma core characterized by parallel (radial) transport and flux surfaces destroyed by m = 1 tearing mode activity associated with dynamo relaxation, a medium confined edge limited by ideal pressure gradient driven modes, and a good confinement region located near the reversal layer. This good confinement region determines the global confinement characteristics of the RFP, and, if limited by resistive interchange modes, is consistent with the Connor-Taylor scaling that has provided a good fit to international RFP results.

Measurements indicate that the wave, launched with a typical frequency range of 15 to 50 kHs from the edge of the machine top, is received by sensing probes located halfway around the torus. The detected signal strength depends weakly on the frequency of the wave and on the phasing of the applied AC signal between the launching probes. Modifications to the spectrum of the edge potential fluctuations are observed rat the launching frequency. These experiments have been extended to the control of the edge plasma fluctuation level using feedback. The launcher is driven by the floating potential of the fluctuating plasma at the location of the launching probes. Edge fluctuations are reduced or excited, depending on the phasing between the launching probes, both locally and at the downstream sensing probes. The fluctuation induced particle flux as well as the local plasma parameters are affected by feedback phasing. C1 UNIV TEXAS,FUS RES CTR,AUSTIN,TX 78712.

After reviewing the issues involved in the final focus and interaction point design for e gamma colliders we compare the luminosities for e gamma colliders in different scenarios. Using a plasma lens to defocus the spent beam is shown to yield higher luminosity than deflecting the beam with a bending magnet. The possibility of configuring the NLC (Next Linear Collider), and the SLC (Stanford Linear Collider) as e gamma colliders is considered together with the physics motivations. It is shown that only with a strong lens, like a plasma lens, is it possible to achieve the desired luminosity. C1 STANFORD UNIV,STANFORD LINEAR ACCELERATOR CTR,STANFORD,CA 94309.

Track location is determined by interpolation of the cathode induced charge, using a new design with intermediate strips between readout nodes to reduce the number of channels and improve position resolution and linearity, Results are reported from tests with an Fe-55 source and a 300 GeV/c muon beam in RD5 at CERN. The beam test demonstrated position resolution of 40 mu m per layer which is less than 1% of the readout pitch, The timing resolution for the entire four-layer detector was 3.6 ns r.m.s. which is adequate for fully efficient beam crossing identification in an LHC experiment.

Such a connector is essential for detectors that use a large number of optical fibers, scintillating or clear. Typical applicators are unscintillating tile/fiber calorimetry and scintillating fiber tracking. We describe the design and performance of two types of small 10-fiber connectors which were developed for the CDF endplug tile/fiber calorimeter. The connectors showed a light transmission of 85-90% with a uniformity of 2.5-3.1%, and a reproducibility of 1%. Use of optical matching material at the joints could further improve the transmission and uniformity but showed instability after heat cycles. C1 UNIV TSUKUBA,INST PHYS,TSUKUBA,IBARAKI 305,JAPAN.

The 20 eV energy resolution of this instrument made it possible to clearly distinguish the argon K-alpha and K-beta,K-gamma complex simultaneously. The intensity ratio of the K-beta,K-gamma to K-alpha emission is 31%, compared to the 8% found in the neutral argon atom. There is strong evidence that the relative intensities of the KL(n) (n = 1-8) transitions do not agree with those obtained with crystal spectrometers.

The chiral behavior of a number of quantities such as the pion mass m(pi)(2), the Bernard-Golterman ratios R and (chi), the masses of nucleons, and the kaon B-parameter are examined to see if the singular terms induced by the additional Goldstone boson, eta', are visible in present data. The overall conclusion (different from what I presented at the lattice meeting) of this analysis is that, with some caveats on the extra terms induced by eta' loops, the standard expressions break down when extrapolating the quenched data with m(q) < m(s)/2 to physical light quarks. I then show that due to the single and double poles in the quenched eta', the axial charge of the proton cannot be calculated using the Adler-Bell-Jackiw anomaly condition. I conclude with a review of the status of the calculation of light quark masses from lattice QCD. RP LOS ALAMOS NATL LAB, GRP T8, MS B285, LOS ALAMOS, NM 87545 USA.

They are the effects of heavy quark modes with large momenta, near the boundary of the Brillouin zone, and the renormalization of the lattice HQET. We argue that even though large momentum modes are present, their contributions to heavy-light bound states and perturbative loop integrals are dynamically suppressed and vanish in the continuum limit. We also discuss a new feature of the renormalization of the lattice HQET not present in the continuum theory, namely that the classical velocity is finitely renormalized.

Then, we analyze the adsorption-desorption transition for a polymer growing near the attractive boundary of a cylindrical cell membrane. We find that the fraction of adsorbed monomers on the boundary vanishes exponentially when the adsorption energy decreases towards its critical value.

If credit is allowed for fuel burnup in the design of casks that are used in the transport of spent light wafer reactor fuel to a repository, the increase in payload can lead to a significant reduction in the cost of transport and a potential reduction in the risk to the public. A portion of the work has been performed at Oak Ridge National Laboratory (ORNL) In support of the U.S. Department of Energy (DOE) efforts to demonstrate a validation approach for criticality safety methods to be used in burnup credit cask design. To date, the SCALE code system developed at ORNL has been the primary computational tool used by DOE to investigate technical issues related to burnup credit. The SCALE code package is a well-established code system that has been widely used in away from reactor applications. Criticality safety analyses are performed via the criticality safety analysts sequences (CSAS) and spent-fuel characterization via the shielding analysis sequence (SAS2H). The SCALE 27-group burnup library containing ENDF/B-IV (actinides) and ENDF/B-V (fission products) data has been used for all calculations. The American National Standards Institute/American Nuclear Society (ANSI/ANS)-8.1 criticality safety standard requires validation and benchmarking of the calculational methods used in evaluating criticality safety limits for applications outside reactors by correlation against critical experiments that are applicable. Numerous critical experiments for fresh PWR-type fuel in storage and transport configurations exist and can be used as part of a validation database. However, there are no critical experiments with burned PWR-type fuel in storage and transport configurations. As an alternative, commercial reactors offer an excellent source of measured critical configurations. Part of the work that has been performed to date to validate the SCALE-4 code system for burnup credit applications using measured critical configurations includes: 1. fresh fuel critical experiments having geometric and nuclear characteristics similar to PWR spent fuel in storage and transport configurations 2. commercial PWR hot-zero-power and hot-full-power reactor critical configurations. The ability to closely predict reactor critical conditions is important in the validation of a methodology for spent-fuel applications because input data are determined based on relatively little detail of reactor core operation. Such limited information is expected to be representative of data available when burnup credit calculations are being performed in the determination of optimum cask loadings. The results reported demonstrate the ability of the ORNL SCALE-4 methodology to predict a value of k(eff) very close to the known value of 1.0, both for fresh fuel criticals and for the more complex reactor criticals. Beyond these results, additional work in the determination of biases and uncertainties is necessary prior to use in burnup credit applications.

The three-dimensional analysis utilizes the flux synthesis technique as well as the explicit method in solving for the spatial flux distribution In the core. Measured data used for comparison are specific powers from a string of fission rate monitors, located In water channels of individual fuel elements, as well as the lobe and fuel element powers. Good agreement was observed in the specific po wet comparison. For the overall pointwise data, the mean errors were within 1.6% with a standard deviation of +/-9%. An excellent agreement was observed for the fuel element power except for a few fuel positions in the corner lobes. Measured ATR startup testing data are also compared with the PDQ calculated values. The PDQ calculated parameters were conservative with respect to measured data. The validation study provided valuable data for assessment of the three-dimensional analytical model and techniques to be employed in the ATR physics analysis. The study also indicated that the PDQ three-dimensional flux synthesis solution technique is an economical and reasonably accurate method for determining global and local three-dimensional power distributions in the core.

Two conceptual designs, both employing metal plate fuel, light water coolant, and a heavy-water primary or secondary reflector region, survived an initial screening process. The Monte Carlo neutronics code (MCNP) was used to select one of these designs for future development. For each design, alternative fuel and pressure vessel materials were considered, and a preferred material was identified for each of the candidate designs. The design judged superior contains seven test regions, each surrounded by Zircaloy fuel annuli and enclosed by its own separate Zircaloy pressure boundary tube.

While it has always been clear that xenon is an important actor in the reactivity response of a system to flux changes, if has been suggested that in very high thermal flux transuranic burning systems, a positive, unstable reactivity growth could be caused by the actinides alone. Initial system reactivity response to flux changes caused by the actinides and xenon are investigated separately. The maximum change in reactivity after a flux change caused by the effect of the changing quantities of actinides is generally at least two orders of magnitude smaller than either the positive or negative reactivity effect associated with xenon after a shutdown or startup. In any transient flux event, the reactivity response of the system to xenon will generally occlude the response caused by the actinides. The capabilities and applications of both the current actinide model and the xenon model are discussed. Finally, the need for a complete dynamic model for the high-flux-fluid-fueled ATW system is addressed. C1 UNIV VIRGINIA,DEPT MECH AEROSP & NUCL ENGN,CHARLOTTESVILLE,VA 22903.

The HRS uses actual plant components to supply key parameters to a digital simulation (and vice versa). To implement the HRS on the Penn State TRIGA reactor, an experimental or secondary control rod drive mechanism is used to introduce reactivity feedback effects that are characteristic of a boiling water reactor (BWR). The simulation portion of the HRS provides a means for introducing reactivity feedback caused by voiding via a reduced order thermal-hydraulic model. With the model bifurcation parameter set to the critical value, the nonlinearity caused by the neutronic-simulated thermal/hydraulic coupling of the hybrid system is evident upon attaining a limit cycle, thereby verifying that these effects are indeed present. The shape and frequency of oscillation (similar to 0.4 Hz) of the limit cycles obtained with the HRS are similar to those observed in operating commercial BWRs. A control or diagnostic system specifically designed to accommodate (or detect) this type of anomaly can be experimentally verified using the research reactor based HRS.

Because the mechanical and corrosion properties of niobium alloys can be significantly altered by oxygen, components must be protected from reactions with oxygen during ground testing. The effect of simultaneous oxidation/corrosion behavior in lithium was determined under several conditions, as well as the conditions under which a thin molybdenum coating was effective in preventing oxidation/corrosion. The effects of oxygen can be mitigated by its reaction with zirconium, and studies were also conducted to evaluate time-temperature relationships for this reaction.

The embedded atom potentials of Voter and Chen (1989) were employed. Point defect energies and threshold displacement energies were also obtained. The defect production efficiency for the 10 keV cascade was 0.27, which is somewhat larger than that found in simulations of metals with a f.c.c. structure. No interstitial clustering and very little vacancy clustering were observed. The threshold displacement energy is lowest for Ni atoms recoiling along [100], 34 eV, followed by the [110], approximate to 54 eV, and [111], approximate to 130 eV. The [111] crowd-ion is the stable interstitial defect. The mixing parameter was small, 6.8 Angstrom(5)/eV. Efficient chemical disordering was nevertheless observed near the centre of the cascade; there the short range order parameter was reduced to 0.24. Statistical methods were developed to follow the atomic structure during the evolution of the cascade and to describe the chemical disorder. C1 UNIV ILLINOIS,DEPT MAT SCI & ENGN,URBANA,IL 61801.

Single phase or alternating layers of MoSi2 and SiC were synthesized by d.c.-magnetron and r.f.-diode sputtering, respectively. Cross-sectional transmission electron microscopy was used to examine several distinct reactions in the specimens when annealed at progressively higher temperatures: crystallization and phase transformation of MoSi2, crystallization of SiC, layer spheroidization, and grain growth. Nanoindentation was employed to characterize the mechanical response of the materials as a function of the structural changes. As-sputtered material exhibits an amorphous structure in both single phase and multilayer forms. Heat treatment induces similar recrystallization behaviour in MoSi2 in both single phase and multilayers. SiC, in single phase form, remains amorphous up to 900 degrees-1 h anneal, while in multilayers it starts to crystallize at 700 degrees C. Annealing at 900 degrees C for 2 h causes the spheroidization of the layering which results in the formation of a nanocrystalline equiaxed microstructure. Abnormal grain growth is observed after the spheroidization. The crystallization process is directly responsible for the hardness and modulus increase in both single phase and multilayered films. A maximum hardness of 25.5 GPa and a modulus of 382 GPa can be achieved through crystallizing both MoSi2 and SiC layers. Prolonged high temperature exposure causes hardness degradation due to grain growth but the modulus remains almost constant. The layered geometry offers better elastic properties (higher modulus) than the single phase films. C1 TECH RES CTR FINLAND,ESPOO,FINLAND. MCMASTER UNIV,DEPT GEOL,HAMILTON,ON L8S 4M1,CANADA.

In order to further enhance J(c), the number of effective flux pinning centres has to be increased. Whether or not twin boundaries are effective pinning sites is of particular interest since twins are inherent defects found in 123. In this investigation, the twin structure of 123 have been modified by mechanical deformation. It is found that the twin density has been increased by deformation processing, and secondary as well as tertiary twins have been generated to relieve the higher level of stresses. In addition, complex twin features and extensive twin interactions are seen in the deformed superconductors. Transport J(c) measurements, however, revealed that J(c) does not increase monotonically with decreasing twin spacing, thereby indicating that twin boundaries are not dominant pinning centres at moderate magnetic field strengths.

Using HeLa cells stably transfected with the HIV-LTR sequence, which transcriptionally drives the chloramphenicol acetyl transferase (CAT) reporter gene, we examined the effects of multiple exposures to UVC (254 nm) on HIV-LTR-CAT expression. Low doses (less than or equal to 5 J m(-2)) had no effect on CAT expression, but up to 29-fold induction was observed with 10 J m(-2) when cells were harvested 48 h after completion of the exposure. Little difference was noted in induction levels when cells were exposed to one 25 J m(-2) dose, viable cells were harvested at 24 h, 48 h or 72 h, and cell lysates were assayed for CAT expression. Two sequential 12.5 J m(-2) exposures, given 24 h apart, resulted in an additive effect on CAT expression; these two exposures produced CAT activity equivalent to that induced following a single 25 J m(-2) dose. This additive effect was not evident at the lower doses (less than or equal to 5 J m(-2)) or at the higher doses. Maximal induction was observed using doses from 25 to 37.5 J m(-2). Multiple exposures with either the low (less than or equal to 5 J m(-2)) or high doses (> 25 J m(-2)) did not result in an additive effect. Our data suggest that HIV-LTR requires a specific threshold UV dose in order to elicit induction; a maximal induction dose is also evident; exposures higher than this maximal dose contribute no more to HIV-LTR induction in viable cells.

The exponential decay constant, mu, is an inverse time-scale that is an invariant of the dynamics of the system and that is unique to deterministic chaos. Theoretical arguments are presented that suggest that mu should be related to the positive Lyapunov exponents. Numerical results are presented from four models with attractor dimensions ranging from 2.009 to 20.28 which suggest that mu is roughly proportional to the sum of the positive Lyapunov exponents, SIGMA lambda(i)+. For these models, the ratio of mu to SIGMA lambda(i)+ lies between the values 0.639 and 2.46 and shows no systematic change with attractor dimension.

Earlier work has shown that GA is the immediate hormonal signal for this growth response, which involves induction of the cell cycle at the G2/M phase transition and subsequent enhancement in the rate of DNA synthesis. In all eukaryotes, onset of mitosis is regulated by the p34(cdc2/CDC28) protein kinase, whose activity is assayed by in vitro phosphorylation of histone H1. It was found that GA enhanced the activity of p34(cdc2/CDC28)-like histone H1 kinase in the intercalary meristem of rice internodes. The enzyme activity showed a sharp peak that correlated with a decrease in the population of cells in the G2 phase during the first 4 h of GA treatment but not with changes in DNA synthesis. The level of histone H1 kinase activity increased again when cell division activity in the intercalary meristem is known to be high. The expression of two cdc2 homologs was examined. The mRNA level of one of these, cdc20s-2, was increased after 1 h of GA treatment, whereas the mRNA level of the other, cdc20s-1, was not affected. Two cDNAs, cycOs1 and cycOs2, which show high homology to cyclin cDNAs, were cloned from rice. They share 75.1% sequence identity at the amino acid level, and both of them are encoded by mRNAs of 1.6 kb. Expression of the two corresponding cyclin genes was enhanced by GA, and the time course of the induction was compatible with a role for both cyclins in regulating the G2/M phase transition. The cyclins were expressed in the intercalary meristem and the elongation zone of the internode, but the GA-induced increase in transcript levels was restricted to the meristem only. The results support the hypothesis that induction of mitosis by GA is brought about by increased p34(cdc2/CDC28) protein kinase activity, which may be the result of transcriptional activation of the cdc20s-2, cycOs1 and cycOs2 genes.

Actions that are designed to protect humans may fail to protect nonhuman populations and ecosystems or may damage ecosystems. However, there is no common scale of health and ecological risk that would allow comparisons to be performed. This paper presents an approach to addressing this problem based on classifying all risks (i.e., health and ecological risks due contaminants and remediation) as insignificant (de minimis), highly significant (de manifestis), or intermediate. For health risks the classification is based on standard criteria. However, in the absence of national guidance concerning the acceptability of ecological risks, new ecological criteria are proposed based on an analysis of regulatory precedents. Matrices and flow charts are presented to guide the use of these risk categories in remedial decision making. The assessment of mercury contamination of the East Fork Poplar Creek is presented as an example of the implementation of the approach. C1 SCI APPLICAT INT CORP,OAK RIDGE,TN.

A simple formula is presented for computing an upper bound for departure from normality in the Frobenius norm. This new upper bound is cheaper to compute than the one derived by Henrici [Numer. Math.,4 (1962), pp, 24 - 40]. Moreover, the new bound is sharp for Hermitian matrices, skew-Hermitian matrices and, in general, any matrix with eigenvalues that are horizontally or vertically aligned in the complex plane. In terms of applications, the new bound can be used in computing bounds for the spectral norm of matrix functions or bounds for the sensitivity of eigenvalues to matrix perturbations.

Single phase films were deposited in a bath of cadmium chloride and sodium thiosulfate at pH = 4 and temperature = 85-degrees-C at a growth rate of 1 nm/min. In the pH range of 3 to 4, the deposition rate is sensitive to cadmium chloride concentration. At higher pH the deposition rate is very low while at lower pH mixed phase films were obtained and homogeneous CdS formation occurred in the bath. The structural and optical properties of the CdS films are also presented and are comparable to films deposited by other methods. CdS/CdTe solar cells with efficiencies over 8% were fabricated using evaporated CdTe to demonstrate the utility of CdS films deposited by this simple technique. The galvanic deposition technique is useful in laboratory settings with limited deposition hardware and limited chemical waste disposal facilities.

These films were cycled in a 1 M LiClO4 propylene carbonate (PC) solution, and exhibited electrochromic behavior upon the electrochemical insertion (reduction) and extraction (oxidation) of lithium. In-situ optical transmittance measurements were investigated in the ultra-violet/visible near-infrared wavelength regions (250-2100 nm). Niobium pentoxide films showed reversible optical switching from 320 to 870 nm, but were found electrochemically inactive in the infrared region. Surface analysis using X-ray photoelectron spectroscopy (XPS) indicated little difference in the chemistry of Nb2O5 films as deposited and lithiated Li(x)Nb2O5 films, as XPS binding energies of Nb and O showed no appreciable shifts. These films were found to be amorphous by X-ray diffraction. Optical transmittance measurements combined with cyclic voltammograms and XPS spectra, revealed that the electrochromic behavior of these films occurs due to the insertion of Li+ cations into niobium pentoxide films. The bronze coloration of the niobium pentoxide films could make them useful as an electrochromic counter electrode for electrochromic devices. C1 TEXAS A&M UNIV,DEPT CHEM ENGN,COLLEGE STN,TX 77843.

This transit has been marked by an evolution from slow, dense coronal streamer belt solar wind through two regions where the rotation of the Sun carried Ulysses back and forth between streamer belt and polar coronal hole flows, and finally into a region of essentially continuous fast, low density solar wind from the southern polar coronal hole. Throughout these large changes, the momentum flux normalized to 1 AU displays very little systematic variation. In addition, the bulk properties of the polar coronal hole solar wind are quite similar to those observed in high speed streams in the ecliptic plane at 1 AU. Coronal mass ejections and forward and reverse shocks associated with corotating interaction regions have also been observed at higher heliolatitudes, however they are seen less frequently with increasing southern heliolatitude. Ulysses has thus far collected data from 20 degrees of nearly contiguous solar wind flows from the polar coronal hole. We examine these data for characteristic variations with heliolatitude and find that the bulk properties in general show very little systematic variation across the southern polar coronal hole so far.

On the other hand, the reverse shocks that commonly bound the trailing edges of the CIRs were observed regularly up to S41.5 degrees, but became weaker with increasing latitude. Only three CIR shocks have been observed poleward of S41.5 degrees; all of these were weak reverse shocks. The above effects are a result of the forward waves propagating to lower heliographic latitudes and the reverse waves to higher latitudes with increasing heliocentric distance. These observational results are in excellent agreement with the predictions of a global model of solar wind flows that originate in a simple tilted-dipole geometry back at the Sun.

The solar wind velocity increased rapidly with latitude from 0 degrees to 35 degrees, then remained approximately constant at higher latitudes. Solar wind density decreased rapidly from 0 degrees to 35 degrees of latitude, and also was approximately constant beyond that latitude. The mass flux similarly decreased away from the equator (but less than the density), whereas the momentum flux was relatively constant. The radial gradient of the entropy at high latitude indicated a value for the polytrope index of about 1.72 (close to adiabatic); the in-ecliptic estimates of radial gradients for temperature and entropy may be biased by temporal variation. A striking increase in the alpha particle-proton velocity difference with latitude is found. C1 LOS ALAMOS NATL LAB, LOS ALAMOS, NM 87545 USA.

In order to study the longitudinal extent of this stream as a function of Ulysses' increasing heliographic latitude, a second point of reference is required to separate spatial and temporal variations. Such a reference point is provided at Jupiter by a class of Jovian radio bursts, whose occurrence rate varies in a predictable way with solar wind speed. Using the in situ and remote observations from Ulysses, the extent of the high speed stream at similar to 5 AU is mapped and compared to the associated coronal hole boundary on the Sun.

This reconnection changed the magnetic topology of the upstream region by converting normal open interplanetary magnetic field into a pair of regions: one magnetically disconnected from the Sun and the other, a tongue, connected back to the Sun at both ends. This process provides a new method for producing both heat flux dropouts and counterstreaming suprathermal electron signatures in interplanetary space. In this paper we expand upon the 29 November case study and argue that reconnection ahead of CMEs should be less common at high heliolatitudes.

One of these events, which was also a magnetic cloud, was directly associated with an event observed by the soft X-ray telescope on Yohkoh in which large magnetic loops formed in the solar corona directly beneath Ulysses. This association suggests that the flux rope topology of the magnetic cloud resulted from reconnection between the ''legs'' of neighboring magnetic loops within the rising CME. The average CME speed (similar to 740 km s(-1)) at these latitudes was comparable to that of the normal solar wind there and is much greater than average CME speeds observed either in the solar wind in the ecliptic plane or in the corona close to the Sun. We suggest that the same basic acceleration process applies to both slow CMEs and the normal solar wind at any latitude. C1 UNIV LONDON IMPERIAL COLL SCI TECHNOL & MED, LONDON, ENGLAND.

There is little, if any, evidence of a latitude gradient. Variances in the field, normalized to the square of the field magnitude, show little change with latitude in variations in the magnitude but a large increase in the transverse field variations. The latter are shown to be caused by the presence of large amplitude, long period Alfvenic fluctuations. This identification is based on the close relation between the magnetic field and velocity perturbations including the effect of anisotropy in the solar wind pressure. The waves are propagating outward from the Sun, as in the ecliptic, but variance analysis indicates that the direction of propagation is radial rather than field-aligned. A significant long-period component of greater than or equal to 10 hours is present. C1 UNIV LONDON IMPERIAL COLL SCI & TECHNOL, BLACKETT LAB, LONDON SW7 2BZ, ENGLAND.

During the in-ecliptic part of the mission, to February 1992, the observed shock waves were first caused mainly by solar transient events following the solar maximum and the reorganisation of the large scale coronal fields. With the decay in solar activity, relatively stable Corotating Interaction Regions (CIRs) were observed betwen 3 and 5.4 AU, each associated with at least one forward-reverse shock pair. During the out-of-ecliptic phase of the orbit, from February 1992 onwards, CIRs and shock pairs associated with them continued to dominate the observations. From July 1992, Ulysses encountered the fast solar wind flow from the newly developed southern polar coronal hole, and from May 1993 remained in the unipolar magnetic region associated with this coronal hole. At latitudes beyond 30 degrees, CIRs were associated almost exclusively with reverse shocks only. A comprehensive list of shock waves identified in the magnetic field and solar wind plasma data from Ulysses is given in Table 1. The principal characteristics were determined mainly from the magnetic field data. General considerations concerning the determination of shock characteristics are outlined in the Introduction.

Although the plasma surrounding the holes was generally stable against the mirror instability, there are indications that the holes may have been remnants of mirror mode structures created upstream of the points of observation. Those indications include: (1) For the few holes for which proton or alpha-particle pressure could be measured inside the hole, the ion thermal pressure was always greater than in the plasma adjacent to the holes. (2) The plasma surrounding many of the holes was marginally stable for the mirror mode, while the plasma environment of all the holes was significantly closer to mirror instability than was the average solar wind. (3) The plasma containing trains of closely spaced holes was closer to mirror instability than was the plasma containing isolated holes. (4) The near-hole plasma had much higher ion beta (ratio of thermal to magnetic pressure) than did the average solar wind. C1 LOS ALAMOS NATL LAB, LOS ALAMOS, NM 87545 USA.

It is found that there are two regions in interplanetary space where the ROID is high: in stream-stream interaction regions and in Alfven wave trains. This latter feature is particularly obvious at high heliographic latitudes when Ulysses enters a high speed stream associated with a polar coronal hole. These streams are characterized by the presence of continuous, large-amplitude (Delta (B) over bar/\B\-1-2,) Alfven waves and an extraordinarily high ROID value (similar to 150 discontinuities/day). In a number of intervals examined, it is found that (rotational) discontinuities are an integral part of the Alfven wave: they represent similar to 90 degrees phase rotation of the wave out of the full 360 degrees rotation of the wave. These large amplitude nonlinear Alfven waves thus appear to be phase steepened. The nonlinear Alfven waves are spherically polarized, i.e., the tip of the perturbation vector resides on the surface of a sphere (a consequence of constant \B\). The best description of this wave plus discontinuity is a ''spherical are polarization''. C1 UNIV LONDON IMPERIAL COLL SCI & TECHNOL, BLACKETT LAB, LONDON SW7 2BZ, ENGLAND.

At the time of these observations, these spacecraft were in the ecliptic plane and separated by 0.4 AU, with Galileo near the Earth at 1 AU and Ulysses at 1.36 AU. From the measured electron arrival times, the propagation path lengths of the electrons to both Ulysses and Galileo were estimated to be significantly longer than the length of the Parker spiral. These long path lengths are interpreted as due to draping of the interplanetary magnetic field lines around a CME. The onset times of the Langmuir waves at Ulysses and Galileo coincided with the estimated arrival time of the 9 keV and 14 keV electrons, respectively.

This pattern is intimately related to the value of T-c, and so possibly to the mechanism of the superconductivity. In the overdoped limit where T-c is reduced, the thermopower is often approximately proportional to temperature, as for conventional metallic diffusion thermopower, and as seen in fullerene superconductors. A remarkably similar pattern of thermopower shifts (but of smaller magnitude) is seen in NbN films. The similarity of cuprate and non-cuprate thermopower suggests a qualitatively similar mechanism.

For PtCl, the theoretical THG spectrum shows three peaks, corresponding to (i) a three-photon resonance at 0.83 eV originating in a M(etal)-M(etal) transition; (ii) a two-photon resonance at 1.5 eV from an M-M band-edge transition; and (iii) a three-photon resonance at 1.6 eV from an M-X transition. The latter two peaks account well for the twin-peak structure seen experimentally. We show that the twin-peak intensity strongly decreases from PtCl to PtBr and disappears for Ptl.

The AFM images are consistent with the surfaces expected from the bulk crystal structure. The surface unit cell parameters of the images correspond to the lattice constants of the bulk crystals. The patterns of the atomic-scale AFM images are dominated by the most protruded H atoms of the en ligands and the most protruded O atoms of the ClO4. anions.

Two oxygen gas flow rates of 5 and 15 seem were used. alpha-MoO3 films were deposited at temperatures of 425-450 degrees C, pressures of 660-1014 mTorr (88.0-135 Pa), with an O-2 flow rate of 5 seem; and at 450-500 degrees C, 300-500 mTorr (40.0-66.7 Pa), with an O-2 flow rate of 5 seem. The polycrystalline films were deposited on silicon (100) wafers and exhibited preferred orientations. Gas phase decomposition of the precursor was significant with temperatures >400 degrees C and pressures >600 mTorr (88.0 Pa), with an O-2 flow rate of 15 seem. Owing to decomposition of the precursor in the gas phase and low gas velocities, the films decreased in thickness in the direction of flow. Thermodynamic equilibrium calculations indicated that alpha-MoO3 was the most stable phase for all deposition conditions. However, alpha-MoO3 was deposited only at high temperatures and pressures. A quadratic model of alpha-MoO3 formation was developed using experimental design for the 5 seem deposition data as a function of temperature and pressure. Both parameters were significant in the formation of alpha-MoO3 films. The films were characterized using X-ray diffraction and X-ray photoelectron, Auger, and laser Raman spectroscopies.

The damage and the site locations of cations in the implanted layer were investigated by Rutherford backscattering cm spectrometry in channeling geometry. The oxidation states of the involved atomic species along the Eu distribution profile were determined by X-ray photoemission spectroscopy (XPS). Following the implantation a fully amorphized layer of about 60 nm is generated and XPS spectra reveal europium in EU(2+) and EU(3+) states. Thermal treatments performed in air at 1050 degrees C for durations up to 12 h have efficently induced both recrystallization of the host lattice and europium diffusion. The XPS results indicate that this diffusion phenomenon can be correlated to a given oxidation state, namely Eu2+. C1 OAK RIDGE NATL LAB,OAK RIDGE,TN 37831.

In theoretical developments, the extended Fourier transform (EFT) is discussed and its necessity for true centering of the sideband in electron holography is shown. A reconstruction procedure for off-axis holograms is then proposed using the advantages of the EFT method. Finally, a standard criterion for assessing the effectiveness of a field emission electron microscope for use in electron holography is proposed and illustrated.

Included were: (1) a potassium sulphate extraction technique with quantification of organic carbon for measurement of microbial biomass; and (2) an arginine ammonification technique for microbial activity. Four profiles consisting of replaced soils were sampled for this study; units included topsoil (mixed mollisol A and B horizons), compacted clay cover (local calcareous Wisconsinan age glacial till), and mixed soil/refuse samples. Internally consistent results across the four profiles and good correlations with other independent indicators of microbial activity (moisture, organic matter content, nitrogen, and phosphorus) suggest that, even though these techniques were developed mainly for natural mineral soils, they are also applicable to disturbed landfill soils.

At present, it is customary to design a capture system using fully penetrating withdrawal wells. Very often, however, only part of the vertical thickness of the aquifer is contaminated, so the question may arise whether a more efficient capture system can be achieved using partially penetrating wells. Very little work has been done on the application of partially penetrating wells to this problem. A new semianalytic method that can be used in determining the geometry of the capture zone for steady state flow to a partially penetrating well that is screened from the top (or from the bottom) of a confined aquifer has been developed. By combining the velocity potentials for flow to the well with that for the regional flow field, a three-dimensional velocity potential that can be used in determining the complete geometry of the capture surface has been developed. The results have shown that with a constant pumping rate the maximum horizontal extent of the capture surface at the top (or bottom) of the aquifer increases as the degree of penetration decreases. As one would expect, the maximum vertical extent increases as the depth of penetration increases. Thus, if one knows the actual location of the contaminant plume, an appropriate combination of the degree of penetration and pumping rate can be selected to create an effective capture zone.

Given discrete observations made on the system response, an optimum parameter set is derived for an appropriate conceptual model by solving the inverse problem using standard optimization techniques. Subsequently, a detailed error analysis is performed, and nonlinearity effects are considered. We discuss the iterative process of model identification and parameter estimation for a ventilation test performed at the Grimsel Rock Laboratory, Switzerland. A numerical model of the ventilation drift and the surrounding crystalline rock matrix is developed. Evaporation of moisture at the drift surface and the propagation of the unsaturated zone into the formation are simulated. A sensitivity analysis is performed to identify the parameters to be estimated. Absolute permeability and two parameters of van Genuchten's characteristic curves are subsequently determined based on measurements of negative water potentials, evaporation rates, and gas pressure data. The performance of the minimization algorithm and the system behavior for the optimum parameter set are discussed. The study shows that a field experiment conducted under two-phase flow conditions can be successfully reproduced by taking into account a variety of physical processes and that it is possible to reliably determine the two-phase hydraulic properties that are related to the given conceptual model.

The valley is mainly planted with mature avocado and orange trees. The surface shear stress and latent and sensible heat fluxes were measured above the trees which are up to 9 m in height. Near-neutral wind speed profile measurements allowed the determination of the watershed surface roughness (to 1.4 m) and the momentum displacement height (z(0) = 7.0 m). The wind speed measurements obtained under unstable atmospheric stability were analyzed using Monin-Obukhov similarity theory. New stability correction functions proposed based on theory and experiments of Kader-Yaglom as well as the now classic Businger-Dyer type functions were tested. The watershed shear stress values calculated using the surface layer wind speed profiles with the new Monin-Obukhov stability functions were found to be improved in comparison with the values obtained with the Businger-Dyer functions under strongly unstable stability conditions. The Monin-Obukhov model with the Businger-Dyer stability correction function underpredicted the momentum flux by 25% under strongly unstable stability conditions, while the new Kader-Yaglom formulation compared well on average (R(2) = 0.77) with the surface eddy correlation measurements for all atmospheric stability conditions. The unstable 100-m drag coefficient was found to be u*(2)/V-100(2) = 0.0182. C1 LAWRENCE LIVERMORE NATL LAB, DEPT BIOL & AGR ENGN, DAVIS, CA 95616 USA.

In the free convection limit the friction velocity can be neglected, thus reducing the measurement needs in practical applications. Some field measurements of the second moment of temperature have indicated that free convection scaling of this statistic may be extended into more dynamic regimes, namely, the ''dynamic-convective'' and, perhaps, the ''dynamic'' regions of the ABL. An advantage of this approach is that the sensible heat flux can be estimated without shear stress measurements. This temperature variance similarity model is applied for a wide range of unstably stratified flows over the dry Owens Lake, in southeastern California. The simple free convection model of the temperature variance is accurate for sensible heat flux estimation across the full range of unstable atmospheric stability conditions.

We fully reconstruct the outgoing meson and, for antiprotons stopped in liquid deuterium, we measure: BR (pd --> pi(0)n) = (7.03 +/- 0.72) x 10(-6), BR (($) over bar pd --> eta n) = (3.19 +/- 0.48) x 10(-6), BR (($) over bar pd --> omega n) = (22.8 +/- 4.1) x 10(-6), BR (($) over bar pd --> eta'n) less than or equal to 14 x 10(-6) (at 95% confidence level). Assuming charge independence, our result for ($) over bar pd --> pi(0)n is compatible with measurements of the only other observed Pontecorvo reaction ($) over bar pd --> pi(-)p. The experimental ratios between the above branching ratios are in fair agreement with both the statistical model and dynamical two-step models (assuming N ($) over bar N annihilation into two mesons, with subsequent absorption of one meson on the remaining nucleon). This agreement suggests that there may be appreciable rates for Pontecorvo reactions producing final state mesons with masses above 1 GeV. C1 RUHR UNIV BOCHUM,D-44780 BOCHUM,GERMANY.

QUARKS; MONTE-CARLO; FRAGMENTATION AB The partial decay width of the Z to b (b) over bar quark pairs has been measured by the DELPHI detector at LEP. b-hadrons, containing b-quarks, were tagged by leptons with high transverse momentum relative to the hadron or by tracks with large impact parameters to the primary vertex. The ratio of the numbers of events with a single such tag to those with two tags was used to estimate the efficiency of the method and to reduce the systematic uncertainty. Combining all methods, the value: [GRAPHICS] was found, where the third error corresponds to a +/-8% uncertainty on the c (c) over bar production width. A maximum likelihood fit to the single and di-lepton distributions gave the branching fraction of the decays of b-quarks to leptons as: [GRAPHICS] C1 IOWA STATE UNIV SCI & TECHNOL,AMES LAB,AMES,IA 50011.

ZEITSCHRIFT FUR PHYSIK C-PARTICLES AND FIELDS LA English DT Article ID DECAYS; QCD AB The forward-backward asymmetries for the processes e(+)e(-) --> c (c) over bar and e(+)e(-) --> b (b) over bar at the Z resonance are measured using identified D*(+/-) mesons. In 905,000 selected hadronic events, taken in 1991 and 1992 with the DELPHI detector at LEP, 4757 D*(+) --> D degrees pi(+) decays are reconstructed. The c and b quark forward-backward asymmetries are determined to be: A(FB)(c (c) over bar) = 0.077 +/- 0.029 (stat) +/- 0.012 (sys), A(FB)(b (b) over bar) = 0.059 +/- 0.062 (stat) +/- 0.025 (sys). Constraining the b asymmetry to the value measured by DELPHI using independent analyses, the charm asymmetry is determined to be: A(FB)(c,const) = 0.068 +/- 0.027 (stat) +/- 0.011 (sys). This result corresponds to an effective electroweak mixing angle measured using charm quark events of: sin2 theta(eff)(lept) = 0.2307 +/- 0.0062 (stat) +/- 0.0026 (sys).

However, we demonstrate that it can be de-excited through the emission of surface plasmons. The observable effect will be a substantial enhancement in the lifetime of dipole-allowed transitions. The recently discovered carbon nanotubules will be explored as potential nanometer scale cylindrical cavities and the lifetimes of excited states of Helium (2p --> 1s) in the carbon nanocavities will be calculated as an example of this nonradiative decay mechanism. The dependence of the transition rate as a function of the radial distance from the tube surface is studied by varying the initial radial quantum number of the center-of-mass wavefunction for an atom confined within the nanotube. The results of the calculation are used to explore the possible application of concentric carbon nanotube structures as TEM waveguides. C1 LOS ALAMOS NATL LAB,DIV THEORET,LOS ALAMOS,NM 87545.

The radicals are produced from photodetachment of a fast, cold negative ion beam. We find that levels of the (A) over tilde, state are strongly predissociated starting with nu(3), = 6 at 35419 cm(-1) excitation energy. Three product channels are identified: (1) CH3 + O, (2) CH2 + OH, and (3) CH3O + H, with channel(1) by far the dominant channel. In channel (1), resolved vibrational structure of the methyl fragment is seen in the translational energy distribution, providing insight into the dissociation dynamics of CH3O. Several thermodynamics quantities are also obtained: D0(CH3-O) = 87.8 +/- 0.3 kcal/mol, Delta H-f,0(0) (CH3O) = 6.8 +/- 0.4, D0(CH3O-H) = 104.0 +/- 0.5, Delta H-acid,H-0(CH3O-H) = 381.4 +/- 0.7, and D0(H-CH2O)= 19.8 +/- 0.4.

Optical pulses 60 fs in duration centered at 620 nm are used to excite the lowest optical band, and the relaxation of the photoexcitations is measured using a time-resolved pump-probe technique. The response is shown quantitatively to follow a time-dependent singlet exciton annihilation process consistent with long-range Forster annihilation. This result is supported by measurements of the dependence of the relaxation on excitation density and probe wavelength, by comparison of the response in thin film, crystalline, and solution samples, and by numerical modeling.

We then introduce a new model. We show that a purely-electronic adiabatic approximation leads to an accurate solution for the system wavefunction in the limit that the molecule-substrate interaction is weak. This produces a configuration-interaction theory that has a Hubbard-like form. We derive semi-empirical parameters for the NO:Pt(111) system and find that the transfer integral for the 2pi-substrate interaction is small for all choices of the screened electron-electron interaction, U. This suggests, for this system, that the substrate indeed adiabatically follows the fluctuations in adsorbate charge which are inherent in a covalent bond. We propose that our model is robust and applies to many adsorbed molecules. We then investigate low-lying excited-states of the metal-molecule bond.

The smaller subfamily (termed HS-2) is comprised of approximately 5 to 25 members, while the larger (termed Sb2) includes approximately 125 to 600 members. Individual members of these Alu subfamilies share distinguishing sets of diagnostic mutations, are well-conserved relative to each other, and have expanded in the human lineage. At least one member from each subfamily is known to be polymorphic in humans. Three newly characterized HS-2 Alu family members as well as three Sb2 Alu repeats are monomorphic (fixed) in humans. The existence of a number of Alu subfamilies that have amplified in parallel within the human genome provides compelling evidence for the simultaneous activity of multiple dispersed Alu source genes.

The model is one-dimensional and transient. The following mechanisms are simultaneously accounted for: (i) the surface heat and mass transport, (ii) the surface oxidation chemical reaction, (iii) the in-depth pyrolysis, (iv) the gas-phase heating by absorption of the radiation and by heat conduction/convection from the solid surface, and (v) the gas-phase chemical reaction. The solutions are obtained numerically with the method of lines. Using lignite and bituminous coal for the simulations, the results confirm that the pyrolysis products absorb a significant amount of the external radiation. Predictions of the ignition times show that both the surface ignition time and the gas-phase ignition time decrease rapidly with increasing radiation intensities. A good agreement between predictions and experiments is obtained. A sensitivity analysis is also carried out with the key kinetic parameters. This analysis establishes an upper limit for surface and pyrolysis activation energies and a lower limit for gas-phase activation energy. Within these limits, the radiative ignition of coals appears as an integration of two consecutive ignition modes: the surface ignition occurs first, which is then followed by the gas-phase ignition. Beyond these limits, the single gas-phase ignition mode is the only ignition mode to prevail. C1 US DOE,PITTSBURGH ENERGY TECHNOL CTR,PITTSBURGH,PA 15236.

In particular, we find that the affine-Virasoro characters of ICFT satisfy heatlike differential equations with fiat connections. As a first example, we solve the system for the general g/h coset construction, obtaining an integral representation for the general coset characters. In a second application, we solve for the high-level characters of the general ICFT on simple g, noting a simplification for the subspace of theories which possess a nontrivial symmetry group. Finally, we give a geometric formulation of the system in which the flat connections are generalized Laplacians on the centrally extended loop group.

The results indicate that all the Pt alloys show enhanced ORR activities relative to a Pt/C electrocatalyst. However, the electrocatalytic activity and activation energy for ORR in the case of Pt/Ni and Pt/Co alloys show marked effect due to different alloying conditions. This was in contrast to Pt/Cr alloy, where both parameters remained unchanged over the range of alloying conditions. Those electrochemical results were correlated with those obtained from in-situ X-ray absorption spectroscopic (XAS) investigations, which provided information on the electronic (Pt Sd-orbital vacancy, from the X-ray absorption near-edge structure) and geometric (Pt-Pt bond distances, from the extended X-ray absorption fine structure) factors. In-situ XAS results indicate that the supported alloys possess higher Pt Sd-orbital vacancies and shorter Pt-Pt bond distances. In addition, the XAS results showed that alloying inhibited chemisorption of oxygenated species (OH) on the Pt at potentials above 0.8 V vs RHE. Correlation of electrocatalytic activities and activation energies for ORR with parameters obtained from in-situ XAS studies indicates that, in the case of Pt/Ni and Pt/Co alloys, higher alloying temperature and longer annealing periods result in higher Pt Sd-orbital vacancies with the geometric parameters remaining unchanged. The Pt/Cr alloy on the other hand revealed no dependence of either the Pt d-orbital vacancies or the geometric parameters on alloying temperature. These observations indicate that the dependence of electrocatalytic activities and activation energy for Pt/Co and Pt/Ni alloys on the thermal history and the absence of such an effect in the Pt/Cr alloy could be related to the differences in the Pt Sd-orbital vacancies.

The =(SiO)(2)= dimer rings are edge-shared tetrahedra, some of which have a lessened reactivity due to an attached silanol. We use infrared spectrometry to show that the dimer rings react with organosiloxane molecules or with water at comparable rates, depending on the structure of the organosiloxane. A polar bond component is a necessary condition for a rapid reaction with dimer rings, since nonpolar organosilanes react orders of magnitude slower than does water or organosiloxanes. Our data show that the important features of the reacting bond that control the rapidity of the reaction are its polarity, steric accessibility, and bond strain. The reactions require approximately 6 orders of magnitude of gas exposure to go from 1% to 99% completion, which shows that the surface is highly heterogeneous. We have applied a simple model of the surface's heterogeneity to our kinetic data, incorporating a linearly distributed activation energy in the ring population. Using this model, a fit to the data shows the spread in activation energy is approximately 40 kJ/mol in all cases. Our results show that the rapid organosiloxane reaction with dimer rings produces hydrolytically stable coupling points that cannot be readily synthesized with conventional silane chemistry.

In this paper, equations relating vapor pressure, temperature, and compositions of the vapor and condensed phases are derived for systems undergoing such transitions. Previously observed unusual phenomena, such as vapor pressures that increase at constant temperature and vapor pressures that increase with decreasing temperature, are explained. It is shown that equilibrium condensed-phase transitions in the presence of the vapor are always hysteretic in the temperature; the transition occurs at a higher temperature in the increasing-temperature direction than in the decreasing-temperature direction. The particular cases of effusion and transpiration experiments are treated in detail. C1 IOWA STATE UNIV SCI & TECHNOL,US DOE,DEPT CHEM,AMES,IA 50011.

The QM/MM method described here is based on our previous QM/MM study of K+/18c6(1) which employed the semiempirical AM1 method for 18c6 and the SPC/e model for H2O. We improve our previous QM/MM method by including MM torsion terms to better describe the energetics of OCCO and COCC rotamers. The torsion terms are parametrized against the ab initio calculations of Jaffe et al. for 1,2-dimethoxyethane.(2,3) The resulting torsion-modified AM1 (TAMI) Hamiltonian is used with our previous QM/MM parameters to describe the conformational energetics of free 18c6 in both H2O and CCl4. The TAM1 method describes optimized geometries and relative energetics for C-i and D-3d configurations of 18c6 slightly better than does the unmodified AM1 method. TAM1 simulation results of OCCO and COCC torsion angle distributions show 18c6 maintains a preorganized oxygen-lined cavity in H2O, in contrast to the simulation in CCl4. The crown ether strongly binds two bridging H2O molecules that help maintain the 18c6 cavity in H2O. These two waters, together, have a simulation average 18c6/H2O stabilization energy of -23.8 kcal/mol. These results contrast markedly with an 18c6/H2O simulation using the unmodified AM1 method. The total QM/MM 18c6/H2O interaction energy is -82.6 kcal/mol and -63.7 kcal/mol for the TAM1 and AM1 simulations, respectively. The AM1 18c6/H2O simulation reveals that 18c6 lacks both a preorganized cavity and the two bound waters. Without correction for rotamer energetics, the AM1 method is not useful for simulations of flexible systems like 18c6. However, semiempirical QM/MM methods, with corrections for torsions, are perhaps preferable to both pairwise-additive and polarizable-empirical force field methods, since the QM treats electronic polarization as a natural part of the simulation.

In the BCS-Eliashberg mean-field theory(1), which is a very good approximation for conventional metals, the phase of the order parameter is unimportant for determining the value of the transition temperature T-c and the change of many physical properties brought about by the transition. Here we argue that superconductors with low superconducting carrier density (such as the organic and high-T-c oxide superconductors) are characterized by a relatively small phase 'stiffness' and poor screening, both of which imply a significantly larger role for phase fluctuations. As a consequence, in these materials the transition to the superconducting state may not display typical mean-field behaviour, and phase fluctuations, both classical and quantum, may have a significant influence on low-temperature properties, For some quasi-two-dimensional materials, notably underdoped high-temperature superconductors, the onset of long-range phase order controls the gross value of T-c as well as its systematic variation from one material to another.

Aerogels(4) are the most highly porous solids known, and can now be prepared from inorganic(5) and organic(6,7) precursors with volume-fraction porosities of up to 99.9% (ref. 8). Aerogels are normally prepared by supercritical extraction of the pore fluid from a wet gel(1), which prevents the network collapse that is otherwise induced by capillary forces. But supercritical processing is expensive, hazardous and incompatible with the processing requirements of many potential applications, thus severely restricting the commercial exploitation of aerogels. Here we describe a means of preparing aerogels by a simple dip-coating method at ambient pressure without the need for supercritical extraction. We add surface groups to the inorganic gel which make drying shrinkage reversible(9): as the solvent is withdrawn, the gel springs back to a porous state. We can generate aerogel films with 98.5% porosity using this approach. We anticipate that it will greatly expand the commercial applications of these materials.

Use of 4 or 5 equiv of the less bulky potassium N-methylanilide in an analogous reaction allows the isolation of the bis-THF adduct Th(NMePh)(4)(THF)(2) (2) or the salt K[Th(MePh)(5)] (3), respectively. The trans amination reaction of the metallacycle {[(Me(3)Si)(2)N]Th-2(CH(2)SiMe(2)NSiMe(3))} with 4 equiv of N-methylaniline in refluxing toluene produces the four-coordinate amide species Th[N(SiMe(3))(2)](2)(NMePh)(2) (4). An X-ray crystal structure determination of 4 revealed a distorted tetrahedral environment about the metal center, with Th-N distances averaging 2.308(7) Angstrom.

The initial step occurs with a rate constant k(U) = 31.4 M(-1) s(-1). The reaction is catalyzed by aquacopper(II) ions, owing to the reaction between Cu2+ and UO2+ (k = 915 M(-1) s(-1)) yielding Cu+, which is rapidly reoxidized by O-2. Cu2+ also reacts with an intermediate produced in the direct reaction of UO2+ and O-2, and the combined effects of Cu2+ aS catalyst and scavenger lead to an unusual dependence of the observed rate constant on [Cu2+]. The role of superoxouranium(VI) and HO2. as reaction intermediates is discussed. C1 IOWA STATE UNIV SCI & TECHNOL,DEPT CHEM,AMES,IA 50011.

This compound may also be prepared through reduction of [Bu(4)N](2)[TcCl6] with either Bu(3)SnH or finely divided Zn followed by treatment with HBF4 . Et(2)O, but in lower yields (approximately 50%). The quadruply bonded species Tc2Cl82- also reacts with HBF4 . Et(2)O in a mixture of acetonitrile and diethyl ether under mild heating to produce small amounts of blue [Tc-2(CH3CN)10][BF4](4) (yield 14%). In addition to the formation of 1, yellow crystals that proved to be the mononuclear Tc(III) species [TcCl2(CH3CN)(4)][BF4] (2) were isolated in 34% yield from the reaction solution.

The system consists of a tetraphenylchlorin as the antenna and a phthalocyanine as the energy acceptor in a poly(vinylpyridine) matrix. Excitation of the antenna leads to strong emission from the acceptor. Long term illumination of the film leads to increasing quantum efficiency for the energy transfer process. Some possible mechanisms for this evolution are discussed as are some possible improvements of the system. C1 BUNDESANSTALT MAT FORSCH & PRUFUNG,ANALYT CHEM ABT,LAB 1014,D-12489 BERLIN,GERMANY.

In the case of photoionization there are two processes, namely, (i) photoionization where the photon is annihilated, and (ii) Compton scattering where the photon is inelastically scattered. In the case of charged particle scattering the ratio of total cross sections tends toward an asymptotic high energy value of 0.26% which is well below the value observed for photons of 1.7% at photon energies between 2 and 12 keV. Theoretical relations between various ratios have been predicted and to some extent confirmed by observations. C1 WESTERN MICHIGAN UNIV,DEPT PHYS,KALAMAZOO,MI 49008.

The segmental mobilities of homopolymer A into homopolymer B, A into A, B into A, and B into homopolymer B hosts were independently determined. These segmental mobilities were observed to differ by orders of magnitude. Using a straightforward formalism based entirely on reptation, reliable predictions of the magnitude of the diffusivity of the diblock were made using these independently determined mobilities. Current theories which address the diffusion of diblock copolymer chains all assume, in the absence of any experiments in this area, that a single, constant, friction factor characterizes the diffusion of diblock chains. It is anticipated that the incorporation of such differences in the relative magnitudes of the segmental mobilities might alter quantitative conclusions of such theories.

The observed correlations of the pi(+/-)N --> D(+/-)X cross section with the projectile charge violates the usual assumption that heavy quark jet fragmentation factorizes. We examine the asymmetry between leading and nonleading charm production as a function of x(F) and p(T)(2) assuming a two-component model combining leading-twist fusion subprocesses and charm production from intrinsic heavy quark Fock stares. We predict a sizable asymmetry at low p(T)(2) and high x(F) from coalescence or me charm quarks with the comoving spectator quarks of the projectile. An intrinsic c ($) over bar c production cross section of 0.5 mu b is sufficient to explain both the magnitude and kinematic dependence of the asymmetry. In contrast, the charm jet hadronization mechanisms contained in PYTHIA predict a sizeable leading charm asymmetry even at low x(F). The two-component model is extended to predict the asymmetry in B meson production in proton-proton and pion-proton interactions.

It is demonstrated that its dependence on incoming photon frequency is the same as that for the single-electron ionization, The ratio ''double-to-single'' ionization in Compton scattering proved to be energy independent and almost coincides with the corresponding value for photoionization. For the He atom it is 1.68%. This surprising result deserves experimental verification. C1 AF IOFFE PHYS TECH INST,ST PETERSBURG 194021,RUSSIA. ST PETERSBURG NUCL PHYS INST,GATCHINA 188350,RUSSIA.

The synthesis is carried out using direct reagent dispensing into the individual reaction wells, A computer controls the sequence in which reagents are dispensed and the timing of the periodic vacuum pulses required to synthesize the desired sequence. Experiments to date have demonstrated the viability of the approach for a variety of test sequences, Results obtained with HPLC analysis demonstrate coupling efficiencies as high as 99.5% under optimized conditions. Use of the oligomers for DNA sequencing templates and as PCR primers has been demonstrated in production applications, The current instrument design consists of a series of discrete reaction chambers in a 12 channel module which can be multiplexed in a 12 x n format where n can be 1-8, i.e. 96 wells. A projected time interval for 12 parallel syntheses is 2.5 h, with 96 syntheses in 3.5 h. Because of the reduced volume of reagents required in the open well format, significant cost savings are projected.

A 3.8 kb linear DNA template consisting of a specific transcription promoter for T7 RNA polymerase placed upstream of 18 tandem repeats of a 207 bp nucleosome positioning sequence derived from the 5S rRNA gene of Lytechinus variegatus was used as a template for chromatin reconstitution. Regularly spaced arrays of nucleosome cores were assembled onto this DNA template from donor histone octamers by salt step dialysis. Histone H1 was incorporated onto free DNA or reconstituted chromatin templates and double label transcription assays were performed. The experiments indicated that histone H1 has a strong inhibitory effect on both transcription initiation and elongation. These effects are especially pronounced on chromatin templates, where both transcription initiation and elongation are virtually halted. The inhibition of transcription elongation appears to result from a dramatic increase in premature termination of transcripts.

We make zeroth-order, normal-mode vibrational assignments to 99 levels; however, their term energies are not well described by the customary (Dunham) expression due to extensive vibrational mixing and the weak C-D bond.

An analysis is presented of the errors arising from truncating the infinite real- and Fourier-space lattice sums in the Ewald formulation. An optimal choice is derived for the Fourier-space cutoff given a screening parameter eta. It is found that the number of vectors in Fourier space required to achieve a given accuracy scales with eta(3). The proposed method can be used to determine computationally efficient parameters for Ewald sums, to assess the quality of Ewald-sum implementations, and to compare different implementations.

The SFG data for surface freezing of eicosane represent a unique study of ordering among nonpolar surface molecules and are consistent with the formation of a solid monolayer of nearly vertical, all-trans molecules at the free liquid surface. For the dodecanol film, the result indicates that the alcohol molecules are nearly all-trans and erect both before and after surface crystallization.

When restricted to this algorithm, Hoffman's result can be expressed as follows: the northwest-corner-rule greedy algorithm solves the two-dimensional transportation problem for all source and supply vectors if and only if the problem's cost array C = {c[i,j]} possesses what is known as the (two-dimensional) Monge property, which requires c[i(1),j(1)] + c[i(2),j(2)] less than or equal to c[i(1),j(2)] + c[i(2),j(1)] for i(1) < i(2) and j(1) < j(2), This paper generalizes this last result to a higher dimensional variant of the transportation problem, We show that the natural extension of the northwest-corner-rule greedy algorithm solves an instance of the d-dimensional transportation problem if and only if the problem's cost array possesses a d-dimensional Monge property recently proposed by Aggarwal and Park in the context of their study of monotone arrays. We also give several new examples of cost arrays with this d-dimensional Monge property. C1 UNIV OSNABRUCK,FACHBEREICH MATH INFORMAT,D-49069 OSNABRUCK,GERMANY.

We identified five cDNA clones encoding receptor tyrosine kinases for which the ligand is known (fibroblast growth factor receptor, platelet-derived growth factor receptor, epithelial growth factor receptor, insulin receptor, and insulin-like growth factor receptor), two putative receptor tyrosine kinases for which the ligand remains to be identified (the products of ryk and the mouse klg homolog), and a novel tyrosine kinase. We cloned cDNAs encoding both the murine and human homologs of this kinase, the sequences of which were subsequently published under the names sky (Ohashi, K., Mizuno, K., Kuma, K., Miyata, T., and Nakamura, T. (1994) Oncogene 9, 699-705) and rse (Mark, M. R., Scadden, D. T., Wang, Z., Gu, Q., Goddard, A., and Godowski, P. J. (1994) J. Biol. Chem. 269, 10720-10728). Mouse sky RNA levels are abundant in mammary tumors derived from transgenic mice that express wnt-1, fgf-3, or both oncogenes in their mammary glands. However, little or no expression of sky is detected in mammary glands from virgin animals or in preneoplastic mammary glands from wnt-1 transgenic mice. Moreover, we find that the human homolog of sky is expressed at elevated levels when normal human mammary epithelial cells are rendered tumorigenic by the introduction of two viral oncogenes. Transient transfection of the human SKY cDNA into the quail fibrosarcoma cell line QT6 reveals that SKY is an active tyrosine kinase that augments the level of cellular phosphotyrosine. Introduction of murine Sky into RatB1a fibroblasts by retrovirus-mediated gene transfer results in morphological transformation, growth in soft agar, and the formation of tumors in nude mice. These data raise the possibility that the Sky tyrosine kinase is involved in the development and/or progression of mammary tumors. C1 NCI,BETHESDA,MD 20892.

Correlated wave functions (valence electrons correlated only) for which intrinsic errors have been estimated include internally contracted multireference configuration interaction (CMRCI), singles and doubles coupled cluster theory with and without perturbative triple excitations [CCSD, CCSD(T)], and second-, third-, and fourth-order Moller-Plesset perturbation theory (MP2, MP3, MP4), For CMRCI and CCSD(T), D-e converges smoothly from below the experimental value and yields the smallest intrinsic errors, -0.8 and -1.6 kcal/mol, respectively. In contrast, for MP2 and MP4, D-e exhibits fortuitously good agreement with experiment for small basis sets but leads to CBS limits that are 11.6 and 3.4 kcal/mol larger than experiment, respectively, Correlation of the Is core electrons is predicted to yield intrinsic errors of less than 1 kcal/mol for CMRCI and CCSD(T), while those for MP2 and MP4 increase still further.

Application of P-31 NMR to distinguish Eu(NO3)(3)-complexed tributyl phosphate from uncomplexed tributyl phosphate (TBP) facilitates an understanding of the fate of these species in the clay hectorite. Solution P-31 NMR studies show dramatic shifts of -156.0 to -172.9 ppm for Eu(NO3)(3) . 6H(2)O dissolved in TBP at TBP:Eu ratios 1:1 to 1:2.5. Pure TBP exhibits a P-31 chemical shift of -0.3 ppm. Mixtures with higher TBP:Eu ratios display lines progressively downfield of -156.0 ppm, reflecting exchange of complexed and free TBP. The Eu(NO3)(3)-complexed TBP adsorbed into hectorite displays a P-31 chemical shift of -180.7 to -193.8 ppm. Clays adsorbed with solutions that are 3:1, 5:1 and 7:1 TBP:Eu display peaks due to complex as well as peaks in the range -4 to -6 ppm attributed to uncomplexed TBP. No evidence of exchange is observed, Spectra of the TBP-adsorbed clay give a TBP line at -0.7 ppm which changes slightly to -5.0 after exchange with Eu(NO3)(3) The Eu(NO3)(3)-exchanged hectorite displays a line at -17.6 ppm after adsorption of TBP. Neither of the latter two samples show indication of complex formation. The hectorite samples exposed to TBP or the complex display (001) d spacings of 17.9-18.4 Angstrom compared to 12.3-12.5 Angstrom for hectorite which has not been exposed to TBP.

The time evolution of the transverse magnetization is monitored at various static magnetic fields. This implies a two-dimensional variation of the signal intensity with respect to both the magnetic field and time axis. Zero quantum coherence between two of the four eigenstates of the radical pair is observed at early times after the laser pulse. The beat frequencies vary significantly with the static magnetic field and extend up to 70 MHz.

We report here steady-state optical absorption, fluorescence, and fluorescence polarization data as well as time-resolved results that detail the significant effects of porphyrin tautomerization on the photophysical properties of a metallo-isoporphyrin, zinc 2,3,5,5',7,8,12,18-octamethyl-13,17-bis(3-methoxy-3-oxopropyl)isoporphyrin perchlorate (2). Besides the red-shifted, low-energy absorption bands diagnostic of metallo-isoporphyrins, 2 exhibits a large stokes shift of its fluorescence emission (similar to 600 cm(-1)) and an unusually short singlet excited-state lifetime at room temperature (140 +/- 15 ps), photophysical properties distinctly different from those of the canonical porphyrin tautomers. The only porphyrins to exhibit marginally similar perturbations of their photophysical properties are those with severely nonplanar macrocycles whose pi systems are significantly destabilized by the conformational distortions and thus approach the interrupted pi systems of isoporphyrins (gentemann et al. J. Am. Chem. Soc. 1994, 116, 7363). In addition to providing the first insights into the photophysical consequences of porphyrin tautomerization, the results for the isoporphyrin further document the sensitivity of the fundamental electronic and excited-state properties of porphyrinic chromophores to modulation of their pi systems in vitro and, by extrapolation, in vivo as well.

The intermittency exponents in this case are phi(q)(K) = q - 1. A simple test for intermittency is proposed making use of the additive property of factorial cumulants for statistically independent subpopulations.

DISTRIBUTIONS; QCD JETS; SPECTRA; ENERGY; Z(0) AB A sample of events enriched in quark pairs was selected in the data recorded by the DELPHI experiment at LEP during 1992 and 1993, by the presence of secondary decay vertices from short-lived particles. Using this sample, the average multiplicities of K-S(0), K-+/-, p((p) over bar), Lambda(<(Lambda)over bar>) and of charged particles in events have been measured, distinguishing the component from fragmentation and the component coming from the decay of b-hadrons. The measurement of the average charge multiplicity in events was used to compute the mean fractional beam energy carried by the primary b-hadron, and the difference in charged particle multiplicity between events and light quark (, , ) events.

The product NADPH of the reaction between glucose-6-phosphate and NADP(+) catalyzed by glucose-6-phosphate dehydrogenase (G6PDH) is monitored. Simultaneously, the agglutination of antibody-coated particles in the presence of G6PDH produces large particles which are counted by light scattering. The correlation between the two parameters indicates that on average only about 35% of the enzyme in individual cells is active. There is more than a 10-fold cell-to-cell variation in the ratios of the two parameters. This indicates that there are multiple mechanisms for the degradation of intracellular enzymes as a function of cell age. (C) 1995 Academic Press, Inc.

The radial pulsating envelope models were computed for two different luminosity levels and for a wide range of effective temperatures. At variance with previous investigations, it was found that at fixed mass and luminosity level an increase in the helium abundance moves the location of the red edge of the instability strip slightly toward higher effective temperatures. The discrepancy between the present investigation and previous ones is connected with the increased spatial resolution of the models which causes a substantial increase in the pulsation driving in the hydrogen ionization region. As a consequence, the red edge shows a weaker dependence on helium than on hydrogen abundance. Moreover, the sequences of models computed at fixed luminosity level and chemical composition show quite clearly that an increase in the stellar mass causes a shift of the red edge toward higher effective temperatures. Finally, the comparison between theoretical red edges and transition line of two metal-poor globular clusters (M15, M68) is also discussed. C1 IST ASTROFIS SPAZIALE,I-00044 FRASCATI,ITALY.

Isolation of large insert DNA clones from libraries containing the target DNA sequence facilitates physical mapping by fluorescence in situ hybridization and allows rapid assignment of genes to cytogenetic bands. Here, we demonstrate the scheme by mapping the human protooncogene trk (NTRK1), a tyrosine kinase receptor type I gene that has earlier been assigned to two different cytogenetic loci. Large DNA insert library screening was carried out by in vitro DNA amplification using oligonucleotide primers flanking exon 4 of trk. The scheme presented here can easily be generalized to map physically very small nonrepetitive genomic DNA fragments or incomplete cDNAs. (C) 1995 Academic Press, Inc.

The superconducting state itself, however, persists up to the pair-breaking value J(d), where the kinetic energy associated with the current overcomes the condensation energy. Within this dissipative regime between J(c) and J(d), the transport behavior displays a series of interesting physical phenomena (free flux flow, pair-breaking effect, etc.) as the Lorentz force and kinetic energy associated with the current sequentially overcome various intrinsic (e.g., pair-condensation and interlayer-coupling) and extrinsic (e.g., flux pinning) interactions relevant to the superconducting state. This review discusses these phenomena in the context of recent experiments where the existence of these effects was demonstrated in high-T-c, superconductors for the first time. Also described are the general principles of the pulsed-current technique used to extend transport measurements to the required high current densities and power-dissipation levels.

From the temperature dependence of the thermal fluctuation behavior, critical exponents are extracted, without fitting parameters, and the fluctuation dimensionality is deduced, Our findings are explicitly consistent with the thin-film structure of the sample and the conductivity behavior model proposed by Maki and Thompson. The first two epitaxial films show 2D dimensionality with a weak Maki-Thompson pair-breaking mechanism above T-c, and a cross-over to a 3D dimensionality near T-c. Moreover, the insensitivity to different substrate-induced lattice strains suggests that lattice strains do not alter the fluctuation behavior. The findings suggest a percolative mechanism in the polycrystalline film. C1 OAK RIDGE NATL LAB,DIV SOLID STATE,OAK RIDGE,TN 37831. AT&T BELL LABS,MURRAY HILL,NJ 07974.

This permits one to explain the change of sign of the order parameter in a natural way and to resolve the seeming conflicts between existing experimental data. The influence of impurity scattering on T-c, the order parameter at T=0 and the density of states, including the energy gap, are studied for the same model. A simple argument shows that the small-angle scattering due to ionized impurities does not change the superconducting parameters, and all changes come from the large-angle scattering. For the vicinity of the singularity the ''out scattering'' has a small probability, since the density of states beyond the singularity is low. Therefore, the suppression of the gap in this vicinity is weak, and the same is true for T-c. On the other hand, the scattering of electrons distant from the singularity into the singular region is much larger, due to the enhanced density of states. Since the order parameter beyond the singularity is still defined by its value in the singular region, it scales with this value and varies only slightly. However, the energy gap in this region, which does not coincide with the order parameter, increases rapidly with impurity concentration so that the gap becomes isotropic in the strong scattering limit. These conclusions agree with preliminary experimental observations. RP ABRIKOSOV, AA (reprint author), ARGONNE NATL LAB,DIV MAT SCI,9700 S CASS AVE,ARGONNE,IL 60439, USA.

Various measurements such as I-V characteristics and critical current as a function of applied field are reported for numerous single boundaries as well as ensembles of boundaries. Most of the single boundaries in Ag doped YBCO showed strong-link behavior in contrast to pure YBCO prepared by a similar method, which showed weak-link behavior.

Correlation between MeV protons and TAE modes is clearly observed. TAE mode amplitude increases exponentially with increasing toroidal mode number up to more than ten. The tendency cannot be explained by present local TAE stability theories. Long suppression of TAE modes after a giant sawtooth crash can be explained by fast ion loss due to the sawtooth crash and evolving q-profile.

The order of activity of Pt(hkl) in H2SO4 increased in the sequence (111) < (100) < (110). These differences are attributed to the structure sensitivity of (bi)sulfate anion adsorption and its inhibiting effect. Very small fluxes (I-R/N < 0.01I(D)) of peoxide were detected at the ring at potentials above 0 V (SCE) on all surfaces. However, below 0 V adsorbed hydrogen affected the partial reduction of oxygen to H2O(2) in the order (1I1) < (100) > (110), with 100% H2O2 formation on Pt(111).

The effects of basis set composition and calculational methods are investigated. The nature of the electronic transitions are examined by decomposing the difference density into the sum of detachment and attachment densities. Counterparts for the three lowest singlet excited states of nitric acid survive relatively unperturbed in chlorine nitrate, while other low lying singlet states of chlorine nitrate appear to be directly dissociative in the CIO chromophore. These results suggest an assignment of the two main peaks in the experimental chlorine nitrate absorption spectrum. In addition, triplet vertical excitations and the lowest optimized triplet geometries of both molecules are studied. C1 UNIV CALIF BERKELEY, DEPT CHEM, BERKELEY, CA 94720 USA.

In the presence of TMPD, however, an electron transfer process ensues, in which the normally persistent radical TMPD(.+) is produced. Under these conditions, the absorbance of the TMPD(.+) radical disappears shortly thereafter. Various kinetic tests have been applied to show that this is the result of a sequence of two electron transfer steps. One is the reaction between CpMo(CO)(3.) (Mo-.) and TMPD, and the other is the reaction between Mo-. and TMPD(.+). The net result of the two reactions occurring in sequence is the disproportionation of the molybdenum radical, rather than the combination reaction that occurs in the absence of this redox-active amine. To the contrary, PhNMe(2) shows no such effect, confirming that these observations are correctly attributed to electron transfer and not to ligand-catalyzed disproportionation. That the TMPD-catalyzed sequence really is disproportionation was confirmed by the chemical identification of the products, CpMo(CO)(3)(-) and CpMo(CO)(3)NCCH3+ Since the disproportionation reaction, with K = 10(7), is less favored than radical combination, with K = 10(16) L mol(-1), this is a case where catalysis yields products that are less favored thermodynamically than those that would otherwise form spontaneously. In that sense, then, the light energy has been stored over long periods of time in intermediates that Lie at a higher Gibbs energy than the thermodynamic products.

The samples were studied both in the presence and in the absence of ruthenium. Single quantum spin counting of protons on silica support with and without ruthenium metal indicated that the total number of hydroxyl groups decreased significantly with increasing reduction temperature over the range of 350-530 degrees C. Two different components shown in static H-1 NMR were found to reveal homogeneous and inhomogeneous broadening via spectral hole burning experiments. H-1 MQ-NMR spin counting, based on the number of MQ coherences observed, showed the existence of small clusters of proton spins on the silica surface. The maximum measured cluster size was 6-7, or less, spins. Segments of silica resembling the 100 face of cristobalite on the surface are postulated to be possible sites for the clusters. The clusters in pure silica became smaller as the reduction temperature increased over 500 degrees C. No such change was detected in the presence of ruthenium.

A substantial reduction in the amplitudes of the Fe-S and Fe-Fe backscattering was observed as the amount of intercalated lithium in the FeS2 lattice was increased from 0 to 2 Li+ equivalents, (Li+)(eq). After the insertion of 2 (Li+)(eq) the second-shell Fe-S interaction and the distant Fe-Fe interactions were no longer discernable in the Fourier transform (FT) data, Curve-fitting analysis of the k(chi)(3)(k) extended X-ray absorption fine structure for this latter material yielded an average Fe-S distance, d(Fe-S) = 2.31 +/- 0.02 Angstrom A, which is about 0.05 Angstrom A longer than d(Fe-S) in crystalline pyrite. In addition, the X-ray absorption near-edge structure revealed a rounding of the otherwise highly structured edge of FeS2 as the amount of inserted lithium was increased, This behavior is consistent with the formation of Fe1-xS and thus supports the assignment made on the basis of in situ Fe-57 Mossbauer effect spectroscopy of the same system.

The spin-polarized electron paramagnetic resonance (EPR) spectra of the oxidized primary donor (P+) depend on tau(H)-, the lifetime of the radical pair P+H- formed prior to P+[QFe(2+)](-). The polarized EPR signal can be described by the sequential electron transfer polarization (SETP) model in which the chemically induced dynamic electron polarization (CIDEP) developed in P+H- is projected onto the correlated radical pair polarization (CRPP) developed in P+[QFe(2+)](-). Replacing the native ubiquinone-10 with various anthraquinones and naphthoquinones alters both the free energy and rate of electron transfer from H- to QFe(2+), which in turn modifies tau(H)-. At long tau(H)- the polarized P+ EPR signal is dominated by the CIDEP component of SETP. At short tau(H)- the signal is dominated by the CRPP component, while at intermediate tau(H)-'S the signal can only be described using the full SETP model. The ranges of tau(H)- where polarization is dominated by interactions on the prior or observed radical pair are influenced by the EPR microwave frequency and RC isotopic composition. Experimental spectra of spin-polarized P+ from a series of Rb, sphaeroides RCs having tau(H)-'s ranging from 0.33 to 25 ns are modeled with SETP. The model accounts for differences in the polarization line shape with deuteration of the RCs or increase in the EPR microwave frequency. C1 ARGONNE NATL LAB,DIV CHEM,ARGONNE,IL 60439.

Ozone has been implicated in the declining health of some forest tree species(2,3) because of its effects on many growth-related processes in controlled studies(3-5). Despite strong evidence that growth of forest tree seedlings can be reduced by ambient levels of ozone(6), there has been little basis for evaluating the threshold and magnitude of direct effects on growth of mature, economically important forest trees. We describe here a five-year study of serial changes in stem circumference of 28 mature loblolly pine (Pinus taeda L.) trees. This study has defined a rough ozone response threshold and quantified short- and longer-term components of growth responses to varying ozone and climate variables. Ozone exposures at greater than or equal to 40 nl l(-1) interacted with low soil moisture and high air temperatures to reduce short-term rates of stem expansion. Annual growth was also inversely related to seasonal ozone exposure and soil moisture stress. Effects varied widely between individual trees and years. Future ozone effects on forests are likely to be influenced by climate change and by projected increases in regional ozone pollution in industrialized countries.

Chemically buoyant plumes are modeled, in order to compare to previously reported laboratory tank experiments. The plume is generated near the bottom of the box and rises and forms a mushroom-head with some entrainment of surrounding fluid. The head flattens at a considerable depth beneath the ridge before rising to the surface. Once the plume reaches the surface the head is quickly divided by the diverging plates, and the waist width is found to have reached a steady-state value, W. The results show that W is proportional to the square root of the volumetric flux of the plume divided by the diverging plate speed, which is consistent with previously reported experimental data. Our scaling law gives an independent method for estimating the volumetric flux of mantle plumes. The calculated plume fluxes are two to four times larger than previous estimates. If plume buoyancy is purely of thermal origin, then excess temperatures can be estimated from the fluxes. For Iceland, Azores and the Galapagos, the calculated excess temperatures are 140, 57, and 51 degrees C respectively, in agreement with recent, independent estimates from modeling of gravity and bathymetry.

By comparison of the proton paramagnetic shifts measured for cobalt(II) complexes of these porphyrins with the dipolar shifts calculated using geometric factors obtained either from crystallographic data or from molecular mechanics structures, it is determined that the conformations of the macrocycles and their substituents are similar in solution and in the crystalline state. Thus, the nonplanar cobalt(II) porphyrins that have well-defined cavity structures in the crystalline state retain these cavities in solution. Variable-temperature proton NMR spectroscopy is used to estimate the dynamic stabilities of the cavity structures. The porphyrins with cavities are found to behave differently from planar porphyrins without cavities with regard to the formation of pi-complexes with 1,3,5-trinitrobenzene. It is suggested that the cavities may modulate a range of porphyrin-substrate interactions, potentially making these porphyrins useful as regio- and stereoselective oxidation catalysts and in the preparation of complexes with well-defined ligand orientations.

This problem has been studied in great detail by numerous investigators when the drops are either perfect conductors or nonconductors and the surrounding fluid is a nondonductor. In this paper, the axisymmetric equilibrium shapes and stability of a nonconducting drop hanging from a nonconducting nozzle that is immersed in a perfectly conducting ambient fluid, a problem that has heretofore not been considered in the literature, are determined by solving the free boundary problem comprised of the Young-Laplace equation for drop shape and an integral equation for the electric field distribution. Here the free boundary problem is discretized by a hybrid technique in which the Young-Laplace equation is solved by the finite element method and the electrostatic problem is solved by the boundary element method. An electrode in the form of a metal rod or an annulus is placed inside and coaxial with the tube whose tip is located a distance H-1 above or below the tube outlet. The electric field is generated by connecting the rod or the annulus electrode to a source of high voltage at potential P and grounding the ambient conducting fluid that surrounds the drop and the tube. When the force due to surface (interfacial) tension is large compared to those due to gravity and electric field, equilibrium drop shapes are sections of spheres and can be parametrized by a parameter -1 less than or equal to D less than or equal to 1: D = 0 corresponds to a hemisphere, as D --> 1 the drop approaches a sphere, and as D --> -1 the drop becomes vanishingly small. The results show that equilibrium families of fixed drop volume, or fixed D, lose stability at turning points with respect to the applied potential, where P = P*. Detailed computations reveal the importance of varying the drop size and geometric factors such as the location of the tip of the electrode H-1, electrode thickness W, and, in the case of the annulus electrode, the inner radius of the annulus R(A) on the value of P*. Except for very skinny drops, i.e., D --> -1, the computed profiles of drops at their limits of stability imply that nonconducting drops in a conducting ambient fluid should become unstable by pinching off near the contact line. This finding agrees with recent experiments on such drops, but stands in marked contrast to previous studies on conducting and nonconducting drops immersed in a nonconducting ambient fluid where the drops become unstable by developing conical tips from which a jet issues. Very skinny drops, however, take on a dog-boned appearance at their limits of stability regardless of whether the drop is a conductor or a nonconductor immersed in a nonconducting ambient fluid or a nonconductor immersed in a conducting ambient fluid.

Instruments to measure the components of the surface heat budget of the polynya were installed on a foremast at the bow of the ship. Measurements of apparent wind speed and direction, air temperature and humidity, long- and short-wave downwelling radiation were made, together with sea surface temperature. The surface heat budget of the polynya derived from these measurements is presented and is shown to be dominated by the net radiation, with a mean value of 133 W m(-2), when calculated over the duration of the cruise. The short-wave insolation. was high during the days with clear skies, reaching over 500 W m(-2) at noon and dropping to about 75 W m(-2) during the sunlit, polar night, with a mean value of 197 W m(-2). In comparison, the mean value of the incident long-wave radiation is 267 W m(-2) In general, the turbulent fluxes were negligible. The measured heat budget is compatible with the observed thermal structure in the surface layers of the polynya and the presumed ice melt during the summer season.

Satellite imagery revealed a convoluted plume of cold water flowing along isobaths from underneath fast ice in the southwestern portion of the polynya toward the northeast. This plume carried relatively high nutrient and low oxygen inventories. Nitrate to phosphate ratios were low in the polar water, consistent with an ultimate source of this water mass in the Pacific sector of the Arctic Ocean. It is hypothesized that the low N:P Arctic outflow might be the cause of nitrate limitation along the east coast of America as far as Cape Hatteras. Gradients of both nutrients and oxygen inventories in the euphotic zone were observed along and across the axis of mean flow within the polynya and are shown to be due to net production of organic matter. On the basis of these spatial gradients of nitrate and oxygen, an assumed along-axis current velocity df 10 cm s(-1), and the observed relationships of biologically removed inorganic carbon with nitrate and oxygen, the net organic matter production was estimated to be 40-60 mmol(C) m(-2) d(-1). This represents the organic carbon available for export from the polynya euphotic zone. Nutrient-deficient and oxygen-rich waters were observed merging with the southward flowing East Greenland Current, suggestive of possible export, however, the ultimate fate of organic carbon produced within the polynya requires further study.

The initial hypotheses were that the polynya would be a site of enhanced secondary production and that the copepod community would be composed of varying proportions of North Atlantic and Arctic species advected onto the Greenland shelf through the Northern and Southern Troughs. Striking contrasts were observed between the northern and southern regions of the Shelf. The southern region was dominated numerically by the North Atlantic species Calanus finmarchicus, while species of Arctic origin (C. glacialis, C. hyperboreus, Metridia longa) dominated in the northern region. The polynya itself contained few of the herbivorous Calanus species but, instead, was dominated by the omnivore M. longa. Secondary production of C. glacialis, represented by egg production rates, was high in all regions (55-88 eggs/female/day). However, because of low abundances of the large bodied Calanus species within the polynya, it is estimated that the herbivorous copepods were riot significant consumers of primary production in the polynya. Fundamentally different pathways for the cycling of carbon may exist in the northern and southern regions. Copepod communities may utilize much of the primary production in the south but only a small proportion of the primary production in the polynya, where significant proportions may be unconsumed.

Biological processes depleted the total inorganic carbon of summer surface waters by up to 2 mol C m(-2) or about 3%. On a regional basis this depletion correlated with depth-integrated values of chlorophyll a, particulate organic carbon, and the inorganic nitrogen deficit. Replacement of this carbon through exchange with the atmosphere was stalled owing to the low wind speeds during the month of the cruise, although model calculations indicate that the depletion could be replenished by a few weeks of strong winds before ice forms in the autumn. These measurements and observations allowed formulation of a new hypothesis whereby seasonally ice-covered regions like the NEW Polynya promote a unique biologically and physically mediated ''rectification'' of the typical (ice free, low latitude) seasonal cycle of air-sea CO2 flux. The resulting carbon sink is consistent with other productivity estimates and represents an export of biologically cycled carbon either to local sediments or offshore. If this scenario is representative of seasonally ice-covered Arctic shelves, then the rectification process could provide a small, negative feedback to excess atmospheric CO2.

Despite suggestions that polynyas may be important localized centers of primary production in polar waters, we found that the St. Lawrence Island Polynya does not obviously enhance the biomass of benthic communities directly below the polynya. However, southward flowing, baroclinic currents generated as a result of brine injection at the polynya edge do appear to have an influence on the biomass and ecological structure of Bering Sea benthic communities south of St. Lawrence Island. These currents appear to affect mean sediment oxygen consumption, surface organic carbon/nitrogen ratios, total organic content, and bottom water ammonia by sweeping phytodetrital matter south and to the west of the island. A particle-reactive, short-lived, natural radioisotope, Be-7, used as an indicator of rapid (days to weeks) deposition of particulate material from the water column, was detected only in surface sediments to the southwest of the island, indicating enhancement of particle deposition to the southwest of the island. Finally, the O-18 content of tunicate cellulose was highest in the polynya region, consistent with increased filter feeding in the late winter when the polynya is present, and presumably promoting primary production in the open water. The Anadyr Current, consisting of nutrient-rich, deeper Bering Sea water that is upwelled onto the shelf in the Gulf of Anadyr, flows west to east in the region south of St. Lawrence Island throughout the year and is the major forcing function for high production in the region. The interaction of Anadyr Water with the winter/spring ephemeral polynya and associated baroclinic currents combine to positively influence benthic communities.

A new approach for decomposition of Raman scattering intensity on to the crystalline and amorphous phase components has been used in analysis of Raman spectra. With increasing ion dose the following was observed: a) the widths of vibrational bands of a-phase significantly increase, while the width of the LO(T) phonon band of c-phase remains unchanged; b) the longitudinal optical phonon band of c-phase completely dissappears, while the transverse optical phonon mode evolves in to a new band of a-phase; c) the wavenumbers of all vibrational bands of a- and c-phase shift to lower values by similar to 10-15 cm(-1). A number of mechanisms possibly accountable for these shifts were analysed and evaluated. C1 RUDJER BOSKOVIC INST,ZAGREB 41000,CROATIA. OAK RIDGE NATL LAB,OAK RIDGE,TN 37831.

Both eyes could be retropulsed normally, and the exophthalmos was induced with ventroflexion. The rabbit had moderate hypercalcemia and a large mediastinal mass that could be seen on thoracic radiographs. The rabbit's condition was unchanged for 5 months. It was reexamined because of weight loss and paroxysmal coughing and, at that time, was thin and tachypneic, and had reduced thoracic compliance. Thoracotomy was performed, and a 5-cm-diameter encapsulated mass, subsequently determined histologically to be thymoma, was removed. The rabbit was euthanatized after surgery because of complications. The periodic exophthalmos and hypercalcemia in this rabbit were believed to be paraneoplastic syndromes.

QUASI-GEOSTROPHIC EIGENANALYSIS SO JOURNAL OF THE ATMOSPHERIC SCIENCES LA English DT Article ID BAROCLINIC WAVES AB The eigenvalue problems for the original Eady model and a modified Eady model (the G model) are examined with no friction, Ekman friction only, and both Ekman and interior friction. When both Ekman and interior friction are included in the models, normal modes show little additional change when compared to the case with Ekman friction only, whereas the relevant ''continuum modes'' have large negative growth rates. Interior friction has a much greater effect on the continuum modes than on the normal modes because inviscid continuum modes have a delta-function vertical profile of potential vorticity q. In contrast, normal modes have much smoother profiles of q in the interior. Streamfunction profiles for the continuum modes are notably different in the two models. The continuum modes in the more realistic G model have sharp peak amplitudes that are not as broad in the vertical as in the Eady model. C1 MOBIL OIL CORP,ENVIRONM HLTH & SCI LAB,PRINCETON,NJ.

The frequency quadrupled Nd:YAG laser (266 nm) was used to stimulate the photoelectron emission. For a normal incident laser pulse, the quantum efficiency of the magnesium at 10(-7) Torr was measured to be 5 x 10(-4), which is more than 20 times the value for copper under similar conditions. After more than 5000 h operation, and despite some optical damage on the cathode surface, no decrease in the quantum efficiency of the magnesium cathode has been observed. The Schottky effect of photoelectron emission was also studied. No electron saturation effect was observed for a train of laser pulses. The photoelectron beam bunch length was measured to be 11 ps FWHM using a microwave kicker cavity, in agreement with a streak camera measurement of the laser pulse length. The measured rms normalized emittance is 2.5 mm mad for a bunch charge of 80 pC, and rms radius of the laser spot 0.2 mm, in agreement with a simple analytical model predictions.

An application of the technique is in the positioning of patients in a proton therapy radiation facility. It makes use of a proton range telescope for density variation and X-Y detectors for planar positioning. The principle of the method was tested at a proton energy of 66 MeV. Good visual quality is seen in the tests. The measurements are compared with detailed Monte Carlo simulations, and good agreement is found. We apply the simulations to high energy proton beams (245 MeV) and show that the method should provide good visual quality and sensitivity for positioning at the higher energies necessary for whole body therapy.

Above the transition temperature, the material behaves like a metal with a scattering rate of approximately 20 cm(-1). In the superconducting state the electrodynamics of both materials is in good agreement with calculations based on a BCS ground state: the penetration depth is temperature independent for T --> 0; while the penetration depth and the coherence length are strongly anisotrop, the superconducting energy gap shows no indications of line nodes.

In both orientations the microwave resistivity basically follows the de behavior for T > 15 K: the crystal undergoes a broad metal-insulator transition at around 50 K. While there are no indications of superconductivity at ambient pressure found in the de resistivity and by ac susceptibility, the microwave resistivity clearly drops at 13 K and again at 5 K, indicating two superconducting phases. When pressure is applied by embedding it in grease, only the well known superconducting phase transition at T-c = 13 K remains. C1 ARGONNE NATL LAB,DIV CHEM & MAT SCI,ARGONNE,IL 60349.

We discuss spin/charge separation found near the phase boundary, analogous to that seen in 2-D high-T-C models and novel long-period states driven by electron-phonon induced spin frustration. We also compare the theoretical predictions with recent experimental evidence for a pressure-induced CDW/AF crossover in the neutral chain [PtBr2] [PtBr4(NH3)(2)]. We compare the experimental pressure dependent behavior of the frequency of the Raman nu 1 mode with the predicted dependence in our two-band, tight-binding, Peierls-Hubbard model for MX chains, and discuss the relative importance of the various terms to reproduce the experimental behavior.

This polymer, in terms of the polyzirconocenesiloxane-2-pyridine (PZSP), was then evaluated for use as thin coating films (thickness, 0.5-1.0 mu m), which provides excellent protection of aluminum (A1) alloys against NaCl-caused corrosion. The PZSP films deposited by simple dip-withdrawing coating methods to A1 displayed the impedance of > 10(6) Omega cm(2) after exposure for 40 days in 0.5 N NaCl solution at 15 degrees C and 3000 h salt-spray resistance.

The thylakoids were isolated from spinach chloroplasts, and PSI reaction centers were extracted from thylakoid membranes. Because thylakoids are relatively thick nonconductors, they were sputter-coated with Pd/Au before imaging. PSI photosynthetic centers and chemically platinized PSI were investigated without sputter-coating. They were mounted on flat gold substrates that had been treated with mercaptoacetic acid to help bind the proteins. With tunneling spectroscopy, the PSI centers displayed a semiconductor-like response with a band gap of 1.8 eV. Lightly platinized (platinized for 1 hr) centers displayed diode-like conduction that resulted in dramatic contrast changes between images taken with opposite bias voltages. The electronic properties of this system were stable under long-term storage. C1 OAK RIDGE NATL LAB,OAK RIDGE,TN 37831.

The MAf is a photochemical intermediate on the path to interstrand XL and has the psoralen intercalated into the helix. The local DNA structure is distorted in both adducts, but it returns to normal within three base pairs. The formation of XL requires displacement of the psoralen toward the initially unmodified strand, accompanied by a change in the hy hybridization of the thymine C-5 and C-6 carbons and a change in the local helix twist. The MAf is intercalated in the helix. There is no significant bend in the helix axis of either the MAf or XL. There are significant changes in the local helix dynamics upon photoadduct formation that may be recognized by cellular DNA repair enzyme systems. We hypothesize that the repair enzymes target lesions by detecting the conformational flexibility of the sugar-phosphate backbone induced by DNA-damaging agents.

A C-12(Lambda) spectrum with 2 MeV (FWHM) energy resolution was measured and core excited states of C-12(Lambda) were clearly identified for the first time. It is discussed that the excitation energies and cross sections of these states will be closely related with the choice of Lambda N interaction models as well as hypernuclear structure. Hypernuclear spectra of 10 Lambda B, Si-28(Lambda), Y-89(Lambda), La-139(Lambda) and Pb-208(Lambda) were also obtained and binding energies of a Lambda hyperon were deduced for each Lambda orbital. The mass number dependence of the Lambda binding energies is, within the present experimental errors, consistent with a calculation based on the Woods-Saxon potential.

Relativistic mean field calculations, designed to reproduce the observed binding energies of ordinary nuclei and of Lambda, Xi and Lambda Lambda hypernuclei, predict a large class of such objects which are stable against strong decay, including the bulk limit A --> infinity, with binding energies per baryon as large as E(B)/A similar to -22 MeV, large strangeness per baryon f(s) similar to 1-1.2, small charge per baryon f(q) similar to -0.1 to 0 and with baryon densities 2-3 times that of ordinary nuclear matter. A straightforward extension of the Bethe-Weizsacker mass formula into the strange domain accounts satisfactorily for all of these features. C1 BROOKHAVEN NATL LAB,DEPT PHYS,UPTON,NY 11973.

Despite these efforts, the Sigma-nucleus interaction is not well understood. Experimental data have been taken on different targets at different momenta and at different conditions. These data suffer from poor resolution and insufficient statistics. Contradictions among the different sets of data often resulted more in clouding the issues than clarifying them. This paper aims at clearing up this long-standing problem. Hypernuclear mass spectra for in-flight (K-,pi(+/-)) reactions from H-1, H-2, Li-6 and Be-9 have been measured. Preliminary results based on analysis of the (K-,pi(+/-)) spectra from Be-9 are discussed. RP SAWAFTA, R (reprint author), BROOKHAVEN NATL LAB,DEPT PHYS,UPTON,NY 11973, USA.

This completes the set of one-loop amplitudes needed for the next-to-leading-order corrections to three-jet production at hadron colliders. We also discuss how to use group theory and supersymmetry to minimize the amount of calculation required for the more general case of one-loop two-quark n-gluon amplitudes. We use collinear limits to provide a stringent check on the amplitudes. C1 STANFORD LINEAR ACCELERATOR CTR, STANFORD, CA 94309 USA.

TOTO binds strongly to all the oligonucleotides used, but usually more than one complex is observed and exchange between different binding sites broadens the lines in the NMR spectra. Complete precipitation occurs when TOTO is bound to small oligonucleotides. Binding to larger oligonucleotides occurs by bis-intercalation. The 1:1 complex of TOTO with the oligonucleotide d(CCGACTGATGC):d (GCATCAGTCGG) gave only one complex that was shown to be a bis-intercalation in the CTGA:TCAG binding site. The binding to this site was also characterized by studying the TOTO complex with the d(CCGCTGAGC):d(GCTCAGCGG) oligonucleotide. NOE connectivities and molecular modelling were used to characterize the complex. The 1:1 complex of TOTO with the oligonucleotide d(CCGCTAGCG):d (CGCTAGCGG) containing a CTAG:CTAG binding site was similarly characterized by NMR. It was concluded that the binding of TOTO to larger oligonucleotides is site selective with CTAG:CTAG as the preferred binding site.

Molecular fluorescence is often used for this task, usually after extensive sample cleanup and separation, due to the speed and the inherent sensitivity of the technique for PACs. When synchronous fluorescence is used for PAC analysis, the amount of sample pretreatment can often be reduced due to the greater selectivity of the technique relative to conventional fluorescence emission. Another method of increasing sensitivity and selectivity is to use lasers as the excitation source in molecular fluorescence. An added advantage of lasers is the high source coupling and fluorescence collection efficiencies when fiber optics are used for remote sensing applications. In this work, the applicability of laser-excited synchronous fluorescence for the analysis of PAC mixtures is evaluated. A prototype laser-excited synchronous luminescence (LSL) instrument has been previously determined to offer significant advantages over conventional laser-excited fluorescence [C.L. Stevenson and T. Vo-Dinh, Appl. Spectrosc., 47 (1993) 430]. An improved version of the LSL instrument is presented here with superior scanning precision and extended wavelength scanning range. In addition to demonstrating the capabilities of the improved LSL instrument for mixture analysis, the sensitivity of this improved instrument is compared to that of a commercial fluorimeter. Finally, the capability of the LSL instrument to further improve selectivity using time-resolved synchronous fluorescence is illustrated.

These inhomogeneous nucleosynthesis models are characterized by a bimodal distribution of baryons in which some regions have a local baryon-to-photon ratio eta approximate to 3 x 10(-10) while the remaining regions are baryon depleted. HBBN scenarios with primordial (H-2 + He-3)/H less than or similar to 9 x 10(-5) necessarily require that most baryons be in a dark or nonluminous form, although new observations of a possible high deuterium abundance in Ly alpha clouds may relax this requirement somewhat. The models described here present another way to relax this requirement and can even eliminate any lower bound on the baryon-to-photon ratio.

Whereas inhomogeneous media are often classified by volume fractions of their constituents, determinations of the local electric field require both microstructural definition and specific electric interaction among defect sites. Herein, we have used a finite element method to determine the local electric field for surface defects in dielectric films. The local electric field is both enhanced and focused in regions about the surface localized defect site. The resulting surface intensities exhibit a much broader range of magnitudes than accommodated by effective medium approximation and random resistor methods.

The penta-coordination of Ni-HOB and Zn-HOB in the RC is similar to that of BChl a in native RC, where the fifth ligand is from a nearby histidine residue. Average Ni-N and Zn-N distances increase by 0.08 Angstrom in Ni-HOB and decrease by 0.04 Angstrom in Zn-HOB-Et(2)O as the modified chlorophylls bind with the RC due to the interaction between the protein and the macrocycle.

The experimental results demonstrate regiospecificity that is enantiomer-specific and confirm our previously reported prediction that (1R)-norcamphor is hydroxylated preferentially at the 5-carbon and (1S) norcamphor at the 6 carbon (Bass, M. B., and Ornstein, R, L, (1993) J. Comput. Chem, 14, 541-548); these simulation results are now compared with simulations involving a ferryl oxygen intermediate. Hydroxylation of (1R)-norcamphor was found at the 5, 6-, and S-carbons in a ratio of 65:30:5 (respectively), whereas (1S)-norcamphor was oxidized to produce a 28:62:10 ratio of the same products. With the exception of the re giospecificity, all of the reaction and physical parameters are similar for each enantiomer of norcamphor. These results show that the position of the carbonyl group on the hydrocarbon skeleton of norcamphor plays a role in determining the average orientation of this substrate in the active site and suggests that hydrogen bonding interactions can aid in directing the regiospecificity and stereospecificity of the hydroxylation reaction catalyzed by cytochrome P450(cam).

In this paper we show that the major attachment site is glycophorin (GP) C/D, and that purified protein 4.1 can bind to two distinct sites on glycophorin C/D. One of these interactions is direct, involving residues 82-98 on glycophorin C (61-77 on glycophorin D), while the other interaction is mediated by p55. We have localized the binding site for p55 on glycophorin C to residues 112-128 (glycophorin D 91-107). We also provide evidence that band 3 is an additional, minor, protein 4.1 binding site. The binding sites for band 3, glycophorin C/D, and p55 are all located within the 30-kDa domain of protein 4.1. We estimate that the relative utilization of the three sites in normal membranes comprises 40% to p55, 40% to GPC/D, and 20% to band 3. The same region of protein 4.1 binds GPC/D and band 3, while the p55 binding site is distinct. The interactions involving protein 4.1 with p55 and p55 with GPC/D are of high affinity (nM), while those involving GPC/D and band 3 are 100 fold lower (mu M). These results suggest that the most significant interactions between protein 4.1 and the membrane are those involving p55. C1 UNIV BRISTOL,DEPT BIOCHEM,BRISTOL B58 1TD,AVON,ENGLAND.

In vitro studies with purified skeletal proteins and various kinases has shown that while phosphorylation of these proteins can modify some of the binary and ternary protein interactions, it has no effect on certain other interactions between these proteins. Most importantly, at present there is no direct evidence that phosphorylation of skeletal protein(s) alters the function of the intact membrane. To explore this critical issue, we have developed experimental strategies to determine the functional consequences of phosphorylation of beta-spectrin on mechanical properties of intact erythrocyte membrane. We have been able to document that membrane mechanical stability is exquisitely regulated by phosphorylation of beta-spectrin by membrane-bound casein kinase I. Increased phosphorylation of beta-spectrin decreases membrane mechanical stability while decreased phosphorylation increases membrane mechanical stability. Our data for the first time demonstrate that phosphorylation of a skeletal protein in situ can modulate physiological function of native erythrocyte membrane.

The samples form continuous arrays on chemical and isotopic covariation diagrams and have similar coarse-granular textures and equilibration temperatures (similar to 950 degrees-1050 degrees C). Sr and Nd isotopic compositions of acid-washed diopsides (epsilon(Nd) = +1.9 to +13.3; Sr-87/Sr-86 = 0.70220 to 0.70328) indicate long-term depletion of Rb relative to Sr and Nd relative to Sm, similar to asthenospheric (mid-ocean ridge basalt (MORB)) mantle. Lead isotopic compositions for all but one of the samples are generally higher in (206)pb, relative to Pb-204, than is typical of MORB (Pb-206/Pb-204 = 18.53 to 19.40 (207)pb/(204)pb = 15.57 to 15.62). The peridotite suite as a whole is significantly depleted in both clinopyroxene and incompatible trace element concentrations (Sm/Nd = 0.5 to 0.8; [Nd] = 1.19-2.69 mu g/g). Isotopic and chemical systematics require that more than one depletion episode occurred in the history of the suite. Assuming that the La Olivina mantle had CHUR-like (chrondrite uniform reservoir) isotopic compositions prior to any of the depletion events, the initial event must have occurred at least similar to 735 Ma ago. The final depletion event could have occurred no more than similar to 280 Ma ago and involved a melt extraction of about 5-10% of the existing mass. Nd isotopic similarities between the peridotites and late Paleozoic arc-related basaltic rocks occurring in the Coahuila terrane to the southeast of La Olivina suggest that the final melting event may have Produced this magmatism. The calculated magnitude of the presumed late Paleozoic melting and melt extraction implies that the La Olivina mantle was asthenospheric at that time. The peridotites contain veins of websterite that have resulted from mid-Cenozoic magmatic activity in the La Olivina region, indicating that the peridotites were in place and attached to the continent prior to the mid-Cenozoic. Increased buoyancy of the newly depleted asthenosphere coupled with a delamination of previously existing lithosphere, suggested by other studies, may have led to the accretion of the La Olivina mantle to the crust by the early Mesozoic (end of the Ouachita orogeny). Several La Olivina peridotites that have Sr-Nd isotopic compositions,that indicate long-term depletion of incompatible elements have subsequently been enriched in these elements. These peridotites contain hydrous minerals and have rare earth element patterns that show enrichment of the light REE relative to the heavy REE. The Sr-Nd-Pb isotopic compositions of these samples indicate that the enriching agent contained isotopic components also present in the two episodes of Cenozoic magmatism in the La Olivina region. However, no satisfactory combination of agents directly related to the two magmatic events can account for the observed isotopic compositions of the enriched samples. This suggests that the enriching agent was not related to either of these magmatic episodes and that the isotopic components are not necessarily coupled together in the mantle regions producing the Cenozoic magmas.

Careful, controlled hydrolysis of 5 in acetone, catalyzed by Bio-Rad AG 50W-X1, leads to 13-cis- and all-trans-13-acetoxy-13-desmethylretinal (1), and cis-1-acetoxy- 7-methyl-9-(2',6',6'-trimethyl-1-cyclohexen-1-yl)-1,4E,6E,8E-nonatetraen-3-one (6). Both 13-cis-1 and all-trans-1 are highly unstable in the presence of weakly acidic material such as silica gel. Both are converted to 6 in the presence of acid. AM1 calculations indicate that 6 is 4.8 kcal/mol more stable than all-trans-1. 13-cis-1 can be purified by HPLC on a cyano column and shown to form a pigment with bacterioopsin. The bacteriorhodopsin analogue, kept in the dark, slowly loses its absorption at 573 nm and in place develops absorption at 406 nm, signaling an alteration in the chromophore's binding to the protein as a protonated Schiff base (PSB). After a substantial drop in the 573 nm absorption, the retinal analogue can not be removed by the standard ethanol-delipidation method which would otherwise remove retinal, bound as a PSB, from native purple membrane or retinal oxime from photobleached purple membrane.

The major product of the oxidation of aniline at room temperature is nitrosobenzene. For 4-substituted N,N-dimethylanilines, the N-oxide is the only product. The rate constants for the oxidation of 4-substituted N,N-dimethylanilines follow a linear Hammett relationship with rho = -1.19. The rate constants for the reaction between CH3Re(O)(2)(O-2), referred to as A, and 4-XC(6)H(5)NMe(2) are as follows: 4-Me, 24.5; 4-H, 18.4; 4-F, 12.7; 4-Br, 8.7; and 4-NO2, 1.9 L mol(-1) s(-1). This shows that electron-withdrawing substituents inhibit the reaction. The corresponding rate constant for the oxidation of aniline is 2.04 +/- 0.11 L mol(-1) s(-1), whereas it is 178 +/- 11 L mol(-1) s(-1) for the oxidation of N-phenylhydroxylamine to nitrosobenzene. A mechanism has been assigned on the basis of the kinetics and product yields. The data are consistent with the attack of the nucleophilic nitrogen atom on one of the peroxidic oxygen atom of A. The kinetics of the reaction of CH3ReO3 and hydrogen peroxide in methanol were also investigated. The formation of the 1:1 peroxide compound A is characterized by an equilibrium constant K-1 = 261 +/- 6 L mol(-1) The equilibration occurs rapidly: k(1) = 1150 +/- 60 L mol(-1) s(-1) and k(-1)= 4.4 +/- 0.4 s(-1) at 25.0 degrees C. The bisperoxide compound, CH3Re(O)(O-2)(2)(H2O), B, forms more slowly. The rate constant is k(2) = 308 +/- 16 L mol(-1) s(-1), and the equilibrium constant is K-2 = 814 +/- 14 L mol(-1) at 25.0 degrees C in methanol. B reacts with the anilines, but much more slowly than A. C1 IOWA STATE UNIV SCI & TECHNOL,AMES LAB,AMES,IA 50011. IOWA STATE UNIV SCI & TECHNOL,DEPT CHEM,AMES,IA 50011.

The values were not different in normal subjects and cocaine abusers. These results did not show any changes in 5-HT2 receptor availability in cocaine abusers as compared to the control subjects.

The effect of doping and of the inter-band coupling constant on the superconducting critical transition temperature and order parameters is analyzed in detail. Within the model a significant enhancement of the superconducting transition temperature is found. The possible connection to high-T-c superconducting materials is discussed.

The compound crystallizes with the symmetry of space group I4/mmm (No. 139) and lattice parameters a=3.72512(5) and c=20.5172(4) Angstrom. The structure is layered and is made of (LaN) (LaN) (LaN) blocks with the rock-salt configuration alternating along the c-axis with Ni2B2 blocks having a fluorite-type arrangement of the atoms. The nitrogen site located on the central layer of the rock-salt block is only 90% occupied, yielding stoichiometry La3Ni2B2N29. Layers are connected to each other along the c-axis by La-N, B-N and Ni-B bonds, while the connections within the layers are provided by La-N and Ni-Ni bonds.

The oxide overlayers are prepared by vapor phase deposition of titanium metal followed by oxidation in 10(-6) Torr O-2. Partial dissolution of the overlayer into the Pt substrate occurs upon annealing to temperatures in excess of 500 degrees C. Annealing in 1 x 10(-6) Torr O-2 at temperatures ranging from 500 degrees C to 700 degrees C leads to a three-fold symmetric structure with a unit cell of 18.2 Angstrom x 18.2 Angstrom. This structure is observed at coverages ranging from 1.0 to 5.0 ML. XPS measurements of this phase show the stoichiometry of TiO2. Heating in vacuum at 650 degrees C to and 850 degrees C leads to a new structure with a unit cell of 18.2 Angstrom x 13.9 Angstrom which is observed at coverages of 1.0 to 1.5 ML. This oxide overlayer is shown by XPS to have the stoichiometry of Ti4O7. Similarities are observed between the ordered overlayers and reported structures of stoichiometric and reduced rutile TiO2 surfaces. Angle resolved XPS measurements of disordered titanium oxide films, formed by annealing at temperatures below 500 degrees C, indicate that reduced Ti3+ is concentrated at the oxide/Pt(111) interface.

Ab initio molecular orbital calculations were performed at the RHF and MP2 levels of theory with split valence basis sets (3-21G, 6-3+G* with effective core potentials for the heavier alkali metals). Comparison with higher level calculations and with experimentally measured bond dissociation energies suggests that the RHF/6-31+G* method provides a reasonable description of cation-water interactions in the smallest (n = 1-3) clusters. Larger clusters, particularly those that involve water-water hydrogen-bonding interactions, require a correlated treatment at the MP2 level. This study serves to calibrate the RHF/6-31+G* and MP2/6-31+G* methods for applications to cation-ligand interactions in more extended systems (e.g., the ion-selective binding of crown ethers and cryptands) for which calculations at higher levels of theory are not currently feasible.

The major oxidation products are CO and CO2 with a product ratio of about 2:1; in contrast, for the nonmodified case, the oxidation of graphite leads only to the formation of CO. XPS results of oxygen adsorbed on a cesium-covered graphitic surface indicate the presence of Cs peroxide and Cs superoxide with Cs peroxide being the most thermally stable species. Oxygen released from Cs peroxide decomposition at elevated temperature enhances the oxidation of graphite and leads to an unusually narrow CO desorption feature, while the graphite oxidation in the absence of Cs is characterized by a broad CO desorption feature. The experiments demonstrate that Cs modification leads to both activity and selectivity changes in the oxidation of surface graphite. We observe a faster carbon removal and also the new reaction pathway: CO2 formation. C1 BROOKHAVEN NATL LAB,DEPT CHEM 555,UPTON,NY 11973. SYNCHROTRON RADIAT RES CTR,HSINCHU 30077,TAIWAN.

Previous attempts to measure sigma have been limited by difficulties in obtaining coincident P- and S-wave data sampling the entire crust(2). Here we report 76 new estimates of crustal sigma spanning all of the continents except Antarctica, We find that, on average, sigma increases with the age of the crust, Our results strongly support the presence of a mafic lower crust beneath cratons, and suggest either a uniformitarian craton formation process involving delamination of the lower crust during continental collisions, followed by magmatic underplating, or a model in which crust formation processes have changed since the Precambrian era.

FRISKEN, WR FURUTANI, KM TI OBSERVATION OF HARD SCATTERING IN PHOTOPRODUCTION EVENTS WITH A LARGE RAPIDITY GAP AT HERA SO PHYSICS LETTERS B LA English DT Article ID POMERON STRUCTURE; ZEUS; CALORIMETER; PHOTON; DIFFRACTION; DETECTOR; COLLIDER; DESIGN; JETS AB Events with a large rapidity gap and total transverse energy greater than 5 GeV have been observed in quasi-real photoproduction at HERA with the ZEUS detector. The distribution of these events as a function of the gamma p centre of mass energy is consistent with diffractive scattering. For total transverse energies above 12 GeV, the hadronic final states show predominantly a two-jet structure with each jet having a transverse energy greater than 4 GeV. For the two-jet events, little energy flow is found outside the jets. This observation is consistent with the hard scattering of a quasi-real photon with a colourless object in the proton.

scattering are studied with the H1 detector at HERA for momentum transfers squared between 10 and 4000 GeV2. It is shown that they can be quantitatively described by perturbative QCD in next to leading order making use of the parton densities of the proton and with the strong coupling constant alpha(s) as a free parameter. The measured value, alpha( )(M(Z)(2)) = 0.123 +/- 0.018, is in agreement both with determinations from e(+)e(-) annihilation at LEP The using the same observable and with the world average.

Liposomes were prepared from egg phosphatidylcholine (ePC) and cholesterol (CH) (2:1, m/m) containing 6 mol% of DSPE-PEG-COOH, and a monoclonal IgG antibody, 34A, which is highly specific to pulmonary endothelial cells, was conjugated to the carboxyl groups of DSPE-PEG-COOH to give various amounts of antibody molecules per liposome. Other immunoliposomes with PEG coating (Type B) or without PEG coating (an earlier type of immunoliposome, Type A) were prepared for comparison. The average molecular weight of PEG in Type B or C immunoliposomes was 2000. Type B and Type C liposomes without antibodies showed prolonged circulation time and reduced reticulo-endothelial system (RES) uptake owing to the presence of PEG. These three different types of 34A-immunoliposomes with 30-35 antibody molecules per vesicle were injected into mice to test the immunotargetability to the lung. The efficiency of lung binding of 34A-Type B was one-half of that of 34A-Type A, though a large amount of 34A-Type B remained in the blood circulation for a long time, suggesting that the steric hindrance of PEG chains reduced not only the immunospecific antibody-antigen binding, but also the RES uptake. The degree of lung binding of 34A-Type C was about 1.3-fold higher than that of 34A-Type A, indicating that recognition by the antibodies attached to the PEG terminal was not sterically hindered and that the free PEG (i.e., that not carrying antibody) was effective in increasing the blood concentration of immunoliposomes by enabling them to evade RES uptake. The latter phenomenon was confirmed by using nonspecific antibody-Type C immunoliposomes (14-Type C), which showed a high blood level for a long time. Our approach provides a simple means of conjugating antibodies directly to the distal end of PEG which is already bound to the liposome membrane, and should contribute to the development of superior targetable drug delivery vehicles for use in diagnostics and therapy.

At different levels of thiophene conversion (0.86-10.2%), the amount of deuterium incorporated into BDE remains constant at 3.47 D atoms per BDE molecule. Unconverted thiophene incorporates 0.42 D atoms at 10.2% thiophene conversion but only 0.05 D atoms at 0.86% conversion. Reaction of 2,5-dihydrothiophene (2,5-DHT) with D-2 at 400 degrees C over PbMo6S8 liberates BDE as the only hydrocarbon product. This BDE incorporates no deuterium. Thiophene and H2S effectively inhibit both BDE hydrogenation and deuterium exchange. The results indicate that during the DDS process, a total of 3.2 deuterium atoms are incorporated into the BDE; 0.83 D are in the D-A-position while 1.2 D are in each of the D-B-and D-C-positions. Several HDS mechanisms proposed in the literature are consistent with these results; two are not. Details of all of these mechanisms are discussed.

Trapped-valence systems exhibit L-edges with clear multiplet structure. The L-edges of trapped-valence (FeFeIII)-Fe-II complexes such as [Fe-2(III,II)(salmp)(2)](-) and [Fe-2(III,II)(bpmp)(mu-O2CC2H5)2](2-) can be interpreted as the sum of distinct Fe(n) and Fe(III) component spectra. Furthermore, an atomic multiplet theory including adjustable ligand field splittings can successfully simulate the Fe(II) and Fe(III) X-ray absorption. Reasonable ligand field parameters are obtained by optimizing the correspondence between calculated and experimental spectra. The XMCD for the [Fe2(III,II)(bpmp)(mu-O2CC2H5)(2)](2-) complex is also reported; it exhibits an interesting magnetic field dependence that reflects the weak magnetic coupling between Fe(II) and Fe(III) ions. In contrast with the trapped-valence complex spectra, the L-edge spectrum for the electronically delocalized complex, [Fe-2(Me(3)tacn)(2)-(mu-OH)(3)](BPh(4))(2) . 2MeOH, exhibits a broad L-edge spectrum with poorly resolved multiplet structure. L-edge spectroscopy is capable of characterizing electron delocalization on a very fast (femtosecond) time scale, while XMCD is an alternative technique for characterizing exchange interactions.

A detailed study of the reference electrode system resulted in a value of -9.0 +/- 0.6 cm(3) mol(-1) for the contribution to Delta V for the net reaction Cyt c(III) + Ag(s) + Cl-(aq) --> Cyt c(II) + AgCl(s) from the reference electrode components Ag(s), Cl-(aq), and AgCl(s). It follows that the absolute molar volume of Cyt c(III) exceeds that of Cyt c(II) by only 5.0 +/- 0.8 cm(3) mol(-1) (mu = 0.1 M, pH = 7), i.e. much less than the value of 24 cm(3) mol(-1) reported in the recent literature. Reaction volumes for a series of intramolecular electron-transfer reactions of the type trans-(NH3)(4)Ru-III(L)-Cyt c(II) --> trans-(NH3)(4)R(II)(L)-Cyt c(III) were found to be 31.7 +/- 1.2 (L = NH3), 21.1 +/- 1.0 (L = isonicotinamide), 23.3 +/- 0.6 (L = pyridine), and 18.6 +/- 0.4 cm(3) mol(-1) (L = 3,5-lutidine). This volume increase is mainly assigned to a decrease in electrostriction during the reduction of the ruthenium center and can be correlated with the number of coordinated ammine ligands. It is concluded that cytochrome c undergoes only a small volume change during electron-transfer reactions. C1 UNIV ERLANGEN NURNBERG,INST INORGAN CHEM,D-91058 ERLANGEN,GERMANY.

The oxidation at 1.20 V/SHE follows logarithmic kinetics over a period of 5 min with all three XAFS features (N-O, N-Pt and the absorption peak) changing identically. However, the reduction at 0.10 V is well fitted by a single exponential on a similar time-scale with N-Pt changing at half the rate at which N-O and absorption peak are changing. When combined with the direct quantitative structural information obtained from XAFS, we find that these reactions on clusters apparently proceed by a different mechanism from that on bulk platinum electrodes in aqueous solution and also suggest a mechanism for the platinum restructuring during these reactions. Therefore the behavior of the clusters may differ from that of bulk electrode surfaces. RP ALLEN, PG (reprint author), LOS ALAMOS NATL LAB,ELECTR RES GRP,POB 1663,LOS ALAMOS,NM 87545, USA.

The time-dependent Stokes shift of Coumarin 480 (C480) and Coumarin 460 (C460) were measured using femtosecond fluorescence upconversion and time-correlated single-photon-counting techniques. The system with a limited number of water molecules was an inclusion complex of Coumarin dyes with gamma-cyclodextrin (gamma CD). The results of molecular dynamics simulations are compared with the observed solvent response in pure water and in the gamma CD cavity. The observed relaxation times range from < 100 fs to 1.2 ns. Solvation of C480 in pure water is observed to occur with time constants of <50 and 310 fs. In sharp contrast with the solvation response in pure water, in the case of the C480/gamma CD inclusion complex, additional long solvation time constants of 13, 109 and 1200 ps are observed. The stoichiometry, structure and dynamics of the Coumarin/gamma CD complexes are also discussed. C1 UNIV CHICAGO,DEPT CHEM,CHICAGO,IL 60637. UNIV CHICAGO,JAMES FRANCK INST,CHICAGO,IL 60637.

Mouse EGF (mEGF), human EGF (hEGF), and transforming growth factor alpha (TGF alpha) bind to the human EGF receptor (EGFR) with similar affinities at pH 7.4. However, the binding properties of these ligands have substantially different pH sensitivities resulting in varying degrees of dissociation from the receptors at lower pH levels characteristic of endosomes. we employed a steady-state sorting assay to determine the fraction of Ligand sorted to recycling versus degradation as a function of the number of intracellular ligand molecules in mouse B82 fibroblasts. mEGF, hEGF, and TGF alpha display significantly different steady-state endosomal sorting patterns which correspond to the extent of their dissociation at endosomal pH. Moreover, several recombinant hEGF mutants with differing affinities exhibit altered endosomal sorting compared to hEGF, demonstrating a similar direct relationship between ligand binding properties and endosomal sorting outcomes. Intracellular trafficking of the EGF ligands was also monitored by measuring the observed degradation rate constants. These likewise show marked differences that correlate with the differing pH sensitivities of the ligands' binding properties. C1 UNIV ILLINOIS,DEPT CELL & STRUCT BIOL,URBANA,IL 61801.

Genetic, biochemical, and molecular analyses indicate that this locus corresponds to an alpha(1,2)fucosyltransferase gene distinct from the genetically-linked H blood group alpha(1,2)fucosyltransferase lo cus. The accompanying paper (Rouquier, S., Lowe, J, B., Kelly, R. J., Fertitta, A L., Lennon, G. G., and Giorgi, D. (1995) J. Biol. Chem. 270, 4632-4639) describes the molecular cloning and mapping of two human DNA segments that are physically linked to, and cross-hybridize with, the H locus. We present here an analysis of these two new DNA segments. One of these, termed Sec1, is a pseudogene, because translational frameshifts and termination codons interrupt potential open reading frames that would otherwise share primary sequence similarity with the H alpha(1,2)fucosyltransferase. The other DNA segment, termed Seca, predicts a 332-amino acid-long polypeptide, and a longer isoform, that share 68% sequence identity with the COOH-terminal 292 residues of the human H blood group alpha(1,2)fucosyltransferase. Sec2 encodes an alpha(1,2)fucosyltransferase with catalytic properties that mirror those ascribed to the Secretor locus-encoded alpha(1,2)fucosyltransferase. Approximately 20% of randomly-selected individuals were found to be apparently homozygous for an enzyme-inactivating nonsense allele (Trp(143) --> ter) at this locus, in correspondence to the frequency of the non-secretor phenotype in most human populations. Furthermore, each of six unrelated non-secretor individuals are also apparentry homozygous for this null allele. These results indicate that Seca corresponds to the human Secretor blood group locus (FUT2) and indicate that homozygosity for a common nonsense allele is responsible for the nonsecretor phenotype in many non-secretor individuals.

This study compares the number and the firing pattern of spontaneously active dopamine (DA) neurons in the substantia nigra pars compacta (SNC) and ventral tegmental area (VTA) in these two strains of rats. This was accomplished using the technique of in vivo extracellular recording. The number of spontaneously active DA neurons in the SNC and VTA of the Lewis rat were significantly lower compared to that of the F344 rats. Furthermore, a greater percentage of SNC and VTA DA neurons in the Lewis rats exhibited a burst firing pattern compared to F344 rats. These findings indicate that F344 and Lewis rats possess differences in mesolimbic DA neuronal activity and this may be a factor in explaining the different propensities between the two strains to self-administer drugs.

It is well known that allowing some fill-in during the incomplete factorization can significantly reduce the number of iterations needed for convergence. Allowing fill-in, however, increases the time for the factorization and for the triangular system solutions. Additionally, it is difficult to predict a priori how much fill-in to allow and how to allow it. The unpredictability of the required storage/work and the unknown benefits of the additional fill-in make such strategies impractical to use in many situations. In this article we motivate, and then present, two ''black-box'' strategies that significantly increase the effectiveness of incomplete Cholesky factorization as a preconditioner. These strategies require no parameters from the user and do not increase the cost of the triangular system solutions. Efficient implementations for these algorithms are described. These algorithms are shown to be successful for a variety of problems from the Harwell-Boeing sparse matrix collection.

The dimer interface is constructed from four helices, two from each subunit, also packed together in a four-helix bundle arrangement. A sulfate ion occupies the aspartate-binding site. All hydrogen bonds made to aspartate are substituted by direct or water-mediated hydrogen bonds to the sulfate, Comparison of the Escherichia coli aspartate-receptor structure with that of Salmonella typhimurium [Milburn, Prive, Milligan, Scott, Yeh, Jancarik, Koshland and Kim (1991), Science, 254, 1342-1347; Scott, Milligan, Milburn, Prive, Yeh, Koshland & Kim (1993). J. Mol. Biol. 232, 555-573] reveals strong conservation in the structure of the monomer, but more divergence in the orientation of the subunits with respect to one another. Mutations that render the Escherichia coli receptor incapable of responding to maltose are either located in spatially conserved sites or in regions of the structures that have high temperature factors and are therefore likely to be quite flexible. The inability of the receptor from Salmonella typhimurium to respond to maltose may, therefore, be because of differences in amino acids located on the binding surface rather than structural differences.

The purified protein from beef heart mitochondria has been crystallized by three groups in three different forms, but progress toward a structure has been hampered by the limited order (resolution) of the crystals. It has been found that under certain conditions the enzyme crystallizes in a new form suitable for X-ray diffraction studies. These crystals belong to space group C222(1) in the orthorhombic system. The cell dimensions are a = 384, b = 118 and c = 177 Angstrom. These new crystals at present diffract to 3.8 Angstrom at best. This is not significantly better than hexagonal [P6(1(5))22] crystals grown, but the new crystals have the advantage of less spot overlap because of face-centered packing which results in systematic extinctions. More importantly, the availability of the same enzyme in multiple crystal forms may allow phase refinement and extension by the method of molecular replacement.

Amorphous thin layers between crystallized grain boundaries of silicate and Si3N4 grains were recognized for both specimens sintered with Dy2O3 and with Yb2O3. In the sample sintered with Dy2O3, very clean grain boundaries between Si3N4 grains which did not contain the heavy elements were frequently recognized, while samples with Yb2O3 had an amorphous grain boundary phase containing Yb. Unusual structures with distorted lattice images in regions rich in Si and O were discovered in crystalline Dy-silicate phases. C1 UNIV CALIF BERKELEY, DEPT MAT SCI, BERKELEY, CA 94720 USA.

These calculations reveal that flaws tend to deflect cracks approaching the interface from their original trajectory if the distance between the flaw and crack tip is small in relation to the flaw size. It is found that the higher the elastic mismatch parameter, the more crack trajectories are attracted to flaws. Other calculations show that materials with interfacial flaws have a significantly increased tendency to deflect cracks along the interface as compared to defect-free materials.

We, in 349 runs, measured mass-transfer rates from naphthalene particles buried in packed beds by passing through air at room temperature. An exact analogy between convection of heat and mass makes it possible to infer heat-transfer coefficients from measured mass-transfer coefficients and fluid properties. Some beds consisted of spheres, naphthalene and inert, of the same, contrasting or distributed sizes. In some runs, naphthalene spheres were buried in beds of crushed shale, some in narrow screen ranges and others with a wide size range. In others, naphthalene lozenges of different shapes were buried in beds of crushed shale in various bed axis orientations. This technique permits calculation of the mass-transfer coefficient for each active particle in the bed rather than, as in most past studies, for the bed as a whole. The data are analyzed by the traditional correlation of Colburn j(D) vs. Reynolds number and by multiple regression of the mass-transfer coefficient on air rate, sizes of active and inert particles, void fraction, and temperature. Principal findings are: local Reynolds number should be based on the active-particle size, not the average for the whole bed differences between shallow and deep beds are not appreciable; mass transfer is 26% faster for spheres and lozenges buried in shale than in all-sphere beds; orientation of lozenges in shale beds has little or no effect on mass-transfer rate; and for mass or heat transfer in shale beds, log(j .epsilon) = -0.0747 -0.6344logN(Re) +0.0592log(2)N(Re).

Habitat choice is imposed first by a heterogeneous pattern of seed dispersal across the patches that make up the landscape and second by environmental variation that favors plant survival in some patches more than in others. Seed-seedling conflicts can occur during both of these phases of habitat choice if conditions or traits that are favorable for seeds are unfavorable for seedlings. During the dispersal phase, smaller seeds may have a greater probability of dispersal than larger seeds, and thus a greater probability of escape from predation, but they contain fewer reserves for support of the establishing seedling. After dispersal, environmental characteristics of a given patch type that lead to disproportionately high seed survival may lead to disproportionately low seedling survival. Considering three hypothetical landscapes, each composed of five patch types, I demonstrate that seed-seedling conflicts can have a major impact on both the overall quantity of recruitment at the landscape level and on the distribution of recruitment among patches. Available empirical evidence suggests these conflicts may be widespread in natural systems. Given their potential importance and extent, seed-seedling conflicts may play a previously unrecognized role in habitat choice. C1 UTAH STATE UNIV,CTR ECOL,LOGAN,UT 84322.

Recently, haplotype analysis of a Batten patient from a consanguineous relationship indicated homozygosity for a D16S298 null allele. PCR analysis with different primers on DNA from the patient and his family suggests the presence of a cytogenetically undetectable deletion, which was confirmed by Southern blot analysis. The migodeletion is embedded in a region containing chromosome 16-specific repeated sequences. However, putative candidates for CLN3, members of the highly homologous sulfotransferase gene family, which are also present in this region in several copies, were not deleted in the patient. If the microdeletion in this patient is responsible for Batten disease, then we conclude that the sulfotransferase genes are probably not involved in JNCL. By use of markers and probes flanking D16S298, the maximum size of the microdeletion was determined to be similar to 29 kb. The microdeletion may affect the CLN3 gene, which is expected to be in close proximity to D16S298. C1 ADELAIDES CHILDREN HOSP, DEPT CYTOGENET & MOLEC GENET, ADELAIDE, SA, AUSTRALIA.

The problem is captured in three differential equations, one for food density and two for the state of the animal cohort, keeping track of body weight and number of individuals, respectively. When the animals efficiently exploit their food to low densities, the model produces cycles. The cycles differ markedly from those produced by traditional predator-prey models. Consumer decline is associated with starvation mortality when individuals lose too much weight. This condition causes a stepwise decline in individual number, each step corresponding to one cycle. Because the survivors of each starvation period grow and because larger animals have lower weight-specific metabolic rates, the nature of the cycles changes over time. They acquire a slow-fast character because of the increasing difference between food and consumer speed and show distinct catastrophic features, as the fast phases are caused by jumping between an over- and underexploited state of the food population, The cycles may either continue toward extinction of the cohort or damp out in a stable state characterized by stunted individual growth. Data from fish communities are closely in line with the specific predictions from this generic model about patterns of die-off and stunted growth. The model behavior is robust. It does not depend on the type of functional response or the way in which mortality increases with individual loss. Furthermore, the same patterns are obtained from an elaborate, realistic individual-based model, which indicates that the results are not artifacts of simplifications like considering all individuals equal and assuming only one food source.

A. Underwood and J. G. Steele (1991) J. lmmunol. Methods 142, 83-94) is also useful for assessing other aspects of protein-surface interactions without radioactively labeled reagents. The method provides a way to compare protein adsorption on various microwell surfaces and to track adhesion of the protein throughout an assay's wash and incubation steps. In cases where adsorption complies with Langmuir-type binding and protein desorption is minimal, sequential ELISA data can be analyzed with a mathematical model to quantitatively estimate the microwell's protein-binding capacity. Even for protein-surface interactions where the mathematical model is not appropriate, characteristics of sequential ELISA binding data qualitatively differentiate between initial adsorption with subsequent desorption and poor initial adsorption of the protein. Using this method, we analyzed the binding of three proteins (rabbit immunoglobulin G, bovine serum albumin, and horse spleen ferritin) to four types of polystyrene microwell surfaces (Immulons 1, 2, 3, and 4). In addition, we examined differences in protein adhesion to the four surfaces when Tween 20 was omitted from the assay's wash buffer or when fewer washes were used. (C) 1995 Academic Press, Inc.

However, the relative contributions of each mechanism remain unknown, The authors evaluated regional body heat content and the extent to which core hypothermia after induction of anesthesia resulted from altered heat balance and internal heat redistribution. Methods: Six minimally clothed male volunteers in an approximate to 22 degrees C environment were evaluated for 2.5 control hours before induction of general anesthesia and for 3 subsequent hours. Overall heat balance was determined from the difference between cutaneous heat loss (thermal flux transducers) and metabolic heat production (oxygen consumption). Arm and leg tissue heat contents were determined from 19 intramuscular needle thermocouples, 10 skin temperatures, and ''deep'' foot temperature, To separate the effects of redistribution and net heat loss, we multiplied the change in overall heat balance by body weight and the specific heat of humans. The resulting change in mean body temperature was subtracted from the change in distal esophageal (core) temperature, leaving the core hypothermia specifically resulting from redistribution. Results: Core temperature was nearly constant during the control period but decreased 1.6 +/- 0.3 degrees C in the first hour of anesthesia. Redistribution contributed 81% to this initial decrease and required transfer of 46 kcal from the trunk to the extremities. During the subsequent 2 h of anesthesia, core temperature decreased an additional 1.1 +/- 0.3 degrees C, with redistribution contributing only 43%. Thus, only 17 kcal was redistributed during the second and third hours of anesthesia, Redistribution therefore contributed 65% to the entire 2.8 +/- 0.5 degrees C decrease in core temperature during the 3 h of anesthesia. Proximal extremity heat content decreased slightly after induction of anesthesia, but distal heat content increased markedly. The distal extremities thus contributed most to core cooling. Although the arms constituted only a fifth of extremity mass, redistribution increased arm heat content nearly as much as leg heat content. Distal extremity heat content increased approximate to 40 kcal during the first hour of anesthesia and remained elevated for the duration of the study. Conclusions: The arms and legs are both important components of the peripheral thermal compartment, but distal segments contribute most. Core hypothermia during the first hour after induction resulted largely from redistribution of body heat, and redistribution remained the major cause even after 3 h of anesthesia.

Escherichia coli K-12 derivatives synthesize apo-GDH but not the cofactor pyrroloquinoline-quinone (PQQ) essential for formation of the holoenzyme, Therefore, in the absence of exogenous PQQ, these strains do not produce gluconic acid and are Mps(-). Evidence is presented to show that expression of a single 396-base Pseudomonas cepacia open reading frame (designated gabY) in E. coli JM109 (a K-12 derivative) was sufficient to induce the Mps(+) phenotype and production of gluconic acid, We present the nucleotide sequence of this open reading frame which coded for a protein (GabY) with a deduced M(r) of 14,235. Coupled transcription-translation of a plasmid (pSLY4 or pGAB1) carrying gabY resulted in production of a protein with an M(r) of 14,750. Disruption of the open reading frame of gabY via site-directed mutagenesis changed the phenotype to Mps(-) and eliminated gluconic acid production. The deduced amino acid sequence of gabY has no apparent homology with those of previously cloned direct oxidation pathway genes but does share regions highly homologous with the histidine permease system membrane-bound protein HisQ as well as other proteins in this family. In the presence of 1 mu M exogenous PQQ, both JM109(pSLY4) and JM109(pGAB1) produced 10 times as much gluconic acid as was seen with either the plasmid or exogenous PQQ alone. The presence of pGAB1 was also sufficient to cause production of gluconic acid in E. coli HB101 (a K-12-B hybrid), In AG121, an apoGDH(-), Tn5 mutant of HB101, the presence of pGAB1 did not cause the production of gluconic acid.

Exploitation of molecular biology techniques has led to development of new methods, such as extraction of nucleic acids from soils or sediments, to study the dominant, nonculturable bacteria. The purpose of this study was to compare three published methods of DNA extraction that fall into two general categories: those in which cells are lysed in sediments (the Ogram and Tsai and methods [A. Ogram, G. S. Sayler, and T. Barkay, J. Microbiol. Methods 7:57-66, 1987; Y. L. Tsai and B. H. Olson, Appl. Environ. Microbiol. 57:1070-1074, 1991]) and those in which cells are removed from sediments prior to lysis (the Jacobsen method [C. S. Jacobsen and O. S. Rasmussen; Appl. Environ. Microbiol. 58:2458-2462, 1992]). DNA yield varied with extraction method; the Ogram method had a significantly higher yield than the other methods. However, DNA extracted via the Ogram method was badly sheared and contained a smaller proportion of eubacterial DNA. The Tsai method was less time consuming than the other methods, but DNA samples were of lower purity. If DNA purity is of paramount concern (as would be the case if PCR was to be performed) and quantity is not important, the Jacobsen method is recommended because of the low concentration of contaminants. If DNA is to be used directly in DNA-DNA hybridizations, the Ogram method is recommended since it gives maximal yields. However, if a Southern blot is to be performed, the Tsai method is recommended because of the high degree of DNA fragmentation observed with the other methods.

It can be used commerically as an intermediate chemical for the manufacture of 1,4-butanediol, maleic anhydride, and many other chemicals. Succinic acid can be produced by the fermentation of carbohydrates. A complete process for the production and purification of succinic acid from carbohydrates has been developed. The process includes fermentation, desalting electrodialysis, water-splitting electrodialysis, and crystallization to produce a pure crystalline succinic acid. This article will present experimental work performed in the development of this process. C1 MICHIGAN BIOTECHNOL INST,LANSING,MI 48909. NATL RENEWABLE ENERGY LAB,GOLDEN,CO 80401.

This process integrates the enzymatic hydrolysis of cellulose to glucose with the fermentation of glucose to ethanol. Its performance depends on the characteristics of the biomass, the quality of the cellulase enzyme complex, and the behavior of the fermentative organism. This study of cellulose conversion progress in batch mode indicates that during the early stage of SSF, cell growth is the rate-determining step in ethanol production. At later times, however, and for most of the duration of the SSF process, enzymatic hydrolysis becomes the limiting factor. Further experimental probing has shown that cellulose accessibility to the enzyme is the key cause of the decreased rate of cellulose hydrolysis. It is therefore concluded that accessibility needs to be enhanced to improve the productivity of the SSF process.

The biological conversion of the organic fraction of these wastes to useful products, including methane and fertilizer-grade residue, through anaerobic high-solids digestion is currently in scale-up development. The suitability of the anaerobic digestion residues as a soil amendment was evaluated through extensive chemical analysis and greenhouse studies using corn as an indicator crop. Additionally, native Samoan soil was used to evaluate the specific application rates for the compost. Experiments established that anaerobic residues increase crop yields in direct proportion to increases in the application rate. Additionally, nutrient saturation was not demonstrated within the range of application rates evaluated for the Samoan soil. Beyond nutrient supplementation, organic residue amendment to Samoan soil imparts enhanced water- and nutrient-binding capacities. C1 COLORADO STATE UNIV,DEPT AGRON,FT COLLINS,CO 80523.

Additionally, the reduction in process water for such a system further improves the economics by reducing the overall size of the digestion system. However, mixing of high-solids materials is often viewed as an energy-intensive part of the process. Although the energy demand for high-solids mixing may be minimized by improving the agitator configuration and reducing the mixing speed, relatively little information is available for the actual horsepower requirements of a mechanically mixed high-solids digester system. The effect of sludge total solids content and digester fill level on mixing power requirements was evaluated using a novel NREL laboratory-scale high-solids digester. Trends in horsepower requirements are shown that establish the optimum parameters for minimizing mixing energy requirements, while maintaining adequate solids blending for biological activity. The comparative relationship between laboratory-scale mixing energy estimates and those required for scaleup systems is also established.

The covalent attachment of pentaammineruthenium(III) to this enzyme resulted in threefold and fourfold enhancements of its hydrolytic activity on carboxymethyl cellulose (CMC) and barley beta-glucan, respectively, as well as endowing it with veratryl alcohol-oxidase activity. Enhancement of hydrolysis was not affected by addition of tartrate or hydrogen peroxide to the reaction mixture. Both native and pentaammineruthenium-modified enzymes had negligible activity on cellobiose and p-nitrophenyl beta-cellobioside (PNPC).

Because of renewed interest in cellulose-degrading bacteria for use in the bioconversion of cellulose to chemical feed stocks and fuels, we re-examined the characteristics of this microorganism to determine its true metabolic potential. Metabolic and physical characterization of NCIMB 10462 revealed that this is an alkalophilic, nonfermentative, gram-negative, oxidase-positive, motile, cellulose-degrading bacterium. The aerobic substrate utilization profile of this bacterium has few characteristics consistent with a classification of P. fluorescens and a very low probability match with the genus Sphingomonas. However, total lipid analysis did not reveal that any sphingolipid bases are produced by this bacterium. NCIMB 10462 grows best aerobically, but also grows well in complex media under reducing conditions. NCIMB 10462 grows slowly under anaerobic conditions on complex media, but growth on cellulosic media occurred only under aerobic conditions. Total fatty acid analysis (MIDI) of NCIMB 10462 failed to group this bacterium with a known pseudomonas species. However, fatty acid analysis of the bacteria when grown at temperatures below 37 degrees C suggest that the organism is a pseudomonad. Since a predominant characteristic of this bacterium is its ability to degrade cellulose, we suggest that it be called Pseudomonas cellulosa.

We have recently developed a technique to photoprecipitate metallocatalysts in situ at the reducing site of PSI in thylakoid membranes, using water-soluble hexachloroplatinate, hexachloroosmiate, and hexachlororuthenate at biological temperature and neutral pH. This technique combined with ''rewiring'' of photosynthesis is a potentially important new field of biometallocatalysis. Potential applications of biometallocatalysis will be addressed in this article. C1 OAK RIDGE NATL LAB, OAK RIDGE, TN 37831 USA.

A necessary step toward this goal is to show how the parameters used in quantitative descriptions of a process (e.g., yield and maintenance coefficients) are related to those describing the metabolism [e.g., Y-ATP, (P/O)]. The ''yield equation'' approach to this problem involves dividing metabolism into the separate pathways for catabolism, anabolism, respiration, and product formation and balancing the production and consumption of reducing equivalents and ATP. The general approach, demonstrated previously for heterotrophic cell growth and products of fermentation, is illustrated by three new examples: the cell yield for chemoautotrophic iron-oxidizing bacteria, the cometabolic degradation of chloroform by methanotrophic bacteria, and the theoretical yield of succinic acid from glucose.

This model is based on the particle mass-transport mechanisms of dispersion and convection, and accounts for the changes in the size of the particles as they are solubilized. Two different cases are compared: one in which the bed is replenished with large coal particles and one in which small particles are fed to the bed. The simulation results indicate that replenishment with small coal particles enhances the overall solubilization rate without significantly increasing the mass elutriated.

Past research in the Alternative Fuels Division of the National Renewable Energy Laboratory has focused on dilute-acid prehydrolysis processes as a means of hydrolyzing the hemicellulose component of biomass. Such processes provide a solid residue that is more easily hydrolyzable by cellulase enzymes, as well as a hemicellulose-sugar component that can be converted by pentose-fermenting microorganisms. This work investigates the technical and economic feasibility of including a separate biomass delignification/fractionation step, either in conjunction with dilute acid prehydrolysis or as an independent pretreatment process. These alternatives would not only solubilize the hemicellulose component of a biomass feedstock, but the lignin fraction as well. The resulting residual solids would be primarily composed of cellulose. The benefits found in converting such material to ethanol may include lower cellulase requirements, shorter bioconversion times, higher effective cellulose concentrations resulting in higher ethanol concentrations, smaller reactor volumes, and more efficient enzyme recycle options. A technoeconomic assessment indicates that improvements in these process parameters can lead to significant savings that can cover the costs of such process additions.

The plant will incorporate operations for feed handling, size reduction, pretreatment, fermentation, distillation, and solids separation. Pilot plant testing of critical equipment at vendor facilities was undertaken to ensure good and reliable designs. Specifically, vendors tested pumping, agitation, and centrifugation of biomass slurries. Sulfuric acid pretreated wood was successfully pumped at solids concentrations up to 30%. Agitation of pretreated biomass slurries was investigated over a range of solids concentrations from 11 to 18.5%. Pretreated and fermented biomass slurries can be successfully dewatered in a centrifuge to a 30% solids concentration. Additionally, metals were tested for corrosion under conditions likely to be encountered in a dilute sulfuric acid prehydrolysis to identify suitable materials of construction for a pretreatment system. Corrosion rates were found to be highly dependent on temperature. Zirconium was the only material that had low corrosion rates at conditions of 2% sulfuric acid and 200 degrees C.

These results suggest that further improvements in ethanol productivity along with good operability may be possible when compared with previous results at the bench scale (40-110 g ethanol/L/h) and present industrial reactors (2-10 g ethanol/L/h). On-line and offline measurement and control systems are also described. Z. mobilis was immobilized in kappa-carrageenan at cell loading of approx 60 g (dry wt)/L of biocatalyst. The system is designed for determining optimal operating conditions for achieving high conversion and productivity with variations in feedstocks, temperature, flow rate, and column sizes.

The study addresses substituting this new technology into an existing plant or using it for a new plant. We have compared the processing steps required by the FBR with conventional technology, and developed process flow schematics, priced required equipment, and generated plant capital and operating cost estimates. This allowed a cost evaluation between the FBR and traditional technologies, such as well-mixed fed-batch fermentation. The study results indicate that the FBR technology can provide a significant reduction in the production costs of ethanol-a savings of >$0.02/gal if inserted into an existing plant, and a savings of >$0.06/gal if used at a new plant.

In this processing scheme, bacteria are immobilized in gelatin beads and are fluidized in a columnar reactor. Solid particles with sorbent capacity for the product are introduced at the top of the reactor, and fall counter currently to the biocatalyst, effecting in situ removal of the inhibitory product, while also controlling reactor pH at optimal levels. Initial long-term fermentation trials using immobilized Lactobacillus delbreuckii have demonstrated a 12-fold increase in volumetric productivity during absorbent addition as opposed to control fermentations in the same reactor. Unoptimized regeneration of the loaded sorbent has effected at least an eightfold concentration of lactic acid and a 68-fold enhancement in separation from glucose compared to original levels in the fermentation broth. The benefits of this reactor system as opposed to conventional batch fermentation are discussed in terms of productivity and process economics.

Several methods were used to examine the influence of nitrogen and phosphorus species on TCE degradation during methane (CH4) injection into contaminated sediments. Laboratory experiments using WSRS ground water revealed that the rate of acetate incorporation into microbial lipids was stimulated when triethyl-phosphate (TEP) or nitrous oxide (N2O) was added. The trend was: CH4 + N2O > CH4 + TEP > CH4 + N2O + TEP > CH4 alone. The degree of stimulation of C-14-TCE mineralization in ground water incubated for 30 d in the laboratory with added methane and nutrients increased in the order: OP = TEP > NH3 + TEP = NH3 > N2O (OP, orthophosphate; NH3, ammonia). Monitoring of WSRS ground water revealed significant differences among sampling wells over time in nutrient concentrations, nitrogen uptake, and urease activity during operations of the bioremediation demonstration. In the field, the addition of TEP + N2O to the pulsed injection of CH4 resulted in dramatic stimulation of TCE-degrading potentials observed in ground water enrichments. The potential to mineralize C-14-TCE in ground water enriched with nutrients in the laboratory increased from <50% of the samples taken during injection of methane in the field to >90% of the samples taken during the injection of CH4 + TEP + N2O treatment. These results demonstrated the dramatic impacts of nitrogen and phosphorus supplements during the in situ bioremediation of chlorinated solvents.

The bacterium possesses nitrile aminohydrolase (EC 3.5.5.1) and amidase (EC 3.5.1.4), which are involved in the transformation of cyanides and nitriles into ammonia and CO2 through the formation of amide as an intermediate. Both of the enzymes have a high selectivity and affinity toward the (CN)-C-- group. The rate of degradation of acetonitrile and sodium cyanide to ammonia and CO2 by the calcium-alginate immobilized cells of P. putida was studied. The rate of reaction during the biodegradation of acetonitrile and sodium cyanide, and the substrate- and product-dependent kinetics of these toxic compounds were studied using free and immobilized cells of P. putida and modeled using a simple Michaelis-Menten equation.

This biomass can decrease the porosity of the soil to such an extent that nutrient injection is no longer possible. In this work, experiments were conducted using a porous media biofilm reactor, operated under constant substrate loading conditions, such that the pressure drop across the reactor was allowed to increase to maintain a constant volumetric flow rate through the reactor. Results suggest that biomass production, and hence biofilm thickness, near the injection feed port is highly sensitive to substrate loading. In addition, these variations in biofilm thickness produce dramatic differences in the pressure drop that is attained across the reactor. Use of the Kozeny-Carman equation can be used to predict that once a critical depth has been exceeded, the pressure drop across the bed will increase exponentially within biofilm depth. This result means that pressure is not a reliable indicator of the onset of pore plugging. C1 WASHINGTON STATE UNIV, DEPT CHEM ENGN, PULLMAN, WA 99164 USA.

A first-order rate expression on attached biomass concentration best reflected effluent substrate concentration for combined data sets. Detachment rate coefficient k(d1) was dependent on initial substrate concentration. Simulation of porous media reactor experiments indicated that responses using higher influent substrate concentrations possessed greater sensitivity to variations in k(d1). Simulations of field bioremediation systems suggest the use of accurate biofilm development kinetics is important in the prediction of well bore biofouling.

P. cellulosa grows on a minimal salts medium supplemented with starch. P. cellulosa was found to secrete an amylase that was not produced when grown on media where cellulose was the only substrate. Therefore, the amylase produced by this bacterium is inducible, whereas production of cellulase was found to be constitutive. The amylase was found to have an apparent molecular weight of approx 97,000 Daltons. The activity of the amylase was found to be highest at alkaline pH values from 7.0 to 8.0, which is similar to the optimal pH for the cellulase.

The distal ends of transmitting and receiving fibers are connected by a small cylindrical section of an optically clear silicone rubber. The silicone rubber acts both as a light pipe and as a selective membrane into which the analyte molecules can diffuse. The sensor has been used to detect volatile organics (trichloroethylene, 1,1-dichloroethylene, and benzene) in both aqueous solutions and in the vapor phase or headspace. Absorption spectra obtained in the near-infrared (near-IR) provide qualitative and quantitative information about the analyte. Water, which has strong broad-band absorption in the near-IR, is excluded from the spectra because of the hydrophobic properties of the silicone rubber. The rate-limiting step is shown to be the diffusion through the Nernstian boundary layer surrounding the sensor and not the diffusion through the silicone polymer. The rate of analyte diffusion into the sensor, as measured by the t(90) values (the time required for the sensor to reach 90% of the equilibrium value), is 30 min for measurements in aqueous solutions and approximately 3 min for measurements made in the headspace. The limit of detection obtained with this sensor is approximately 1.1 ppm for trichloroethylene in an aqueous solution. C1 UNIV CALIF BERKELEY,LAWRENCE BERKELEY LAB,BERKELEY,CA 94720.

No partitioning of Cr, Mo and Mn was observed between the cementite and ferrite in the early stages of tempering. No concentration spikes of substitutional solute elements were found at the transformation interface on an atomic scale. The enrichment of Cr, Mn and Mo in the cementite during prolonged ageing, before the onset of soft impingement, was found to be the same in both the low and high carbon alloys. The results provide further support for the theory that cementite precipitates from supersaturated ferrite via a paraequilibrium displacive transformation mechanism.

In both conventional and CRE-type stainless steel welds, during high temperature service, various microstructural changes take place such as the formation of M(23)C(6) carbide networks along the austenite(gamma)-ferrite (delta) interface, the formation of sigma (sigma) phase, and the dissolution of ferrite. Boron-containing CRE welds exhibit similar microstructural evolution as that of conventional types 308 stainless steel welds. As boron may segregate to the ferrite-austenite interface and thereby modify the austenite-M(23)C(6) carbide interface, the distribution of boron was measured with an atom probe field ion microscope. Atom probe analysis revealed significant boron and carbon enrichments along the ferrite-austenite boundary in the as-welded state. The ratio of the carbon-to-boron concentration at the interface was found to be similar to 4.

Atom probe analysis revealed significant depletions of copper and gold in the matrices after neutron irradiation. High number densities of small coherent zones on the {100}alpha planes were observed by both transmission electron microscopy and field ion microscopy. A maximum gold concentration of similar to 4 at% Au was found in the coherent zones for material neutron-irradiated at 290 degrees C to a fluence of similar to 1.2 x 10(23) n m(-2).

Methods based on simple geometrical models for all boundary orientations in the field ion specimen and on the Gibbsian interfacial excess are presented. Atom probe results for phosphorus segregation in two Russian pressure vessel steels were found to be in good agreement with the predictions based on McLean's model of grain boundary segregation.

A comparison with microstructures from Fe-45%Cr alloys aged at 500 degrees C showed that the activation energy for diffusion was approximately 2.3 eV. The increase in the scale and composition of the alpha/alpha' domains was measured as a function of ageing time for both heat treatment temperatures. These parameters were also related to the increase in microhardness and development of interface structure between the domains. Simulations using the dynamic Ising model show that the interfaces between the alpha and alpha' phases should be smoother at lower ageing temperatures for a given scale of decomposition. A comparison between the experimental results and simulations is discussed. C1 OAK RIDGE NATL LAB, DIV MET & CERAM, OAK RIDGE, TN 37831 USA.

The change in the microhardness was found to be substantially higher in the duplex stainless steel than in the iron-chromium model alloy. Atom probe results have revealed that the composition amplitude of the spinodal decomposition is significantly lower in the binary iron-chromium alloy than in the commercial duplex stainless steel. It is therefore concluded that the behavior of binary FeCr alloys does not provide an accurate basis for predicting the extent of the decomposition in the commercial duplex stainless steels.

Experimental evidence leading to the confirmation of the exchange mechanism on the (110) and (100) surfaces of fee metals is presented along with a discussion of the fundamental and technological implications of atomic exchange processes. Chemical trends in the preferred diffusion mode for various adatoms on fee (100) surfaces are extracted from field ion microscope investigations. The results indicate that the propensity for exchange versus hopping motion is not correlated with macroscopic surface or bulk properties of the metals, but may be correlated with the amount of surface-atom relaxation induced by the presence of the adatom. Also discussed are the role of exchange processes in the diffusion of small clusters and the effect of an externally applied electric field on the exchange-displacement rate and transport mechanism.

Glycidyl 2-methylphenyl ether and 2-phenoxy ethanol were selected as the model compounds of epoxy resins and were used as adsorbates in addition to some simpler substituted benzenes. It was found that on zinc oxide, water was adsorbed coordinatively on zinc sites and the heat of adsorption was 89 kJ/mol while on iron oxide, water was adsorbed physically and the heat of adsorption was 55 kJ/mol. On zinc oxide, the adsorption of benzene, toluene and alpha,alpha,alpha-trifluorotoluene was interfered with water while the adsorption of phenol and the epoxy model compounds was not affected by water. On iron oxide, none of these organic molecules were replaced by water. Based on these findings, it was concluded that the adhesion mechanism of the epoxy resin proposed in the previous paper holds even when the oxide surfaces are covered with water. Namely, the adhesion is due to the chemical bond formed by C-O bond dissociation to form surface phenoxy species. C1 UNIV CALIF BERKELEY,LAWRENCE BERKELEY LAB,DIV MAT SCI,BERKELEY,CA 94720.

Design: Single photon emission computed tomography using the blood flow tracer I-123-N-isopropyl-p-iodoamphetamine was performed at initial evaluation and was used to predict the rate of cognitive decline over a follow-up period from 1 to 4 years. Setting: Outpatient university dementia clinic and center for functional imaging. Participants: Twenty-nine patients met National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer's Disease and Related Disorders Association criteria for probable or possible AD. Results: Temporal lobe regional cerebral blood flow ratio at initial evaluation correlated with rate of decline in Mini-Mental State Examination over the longitudinal follow-up. Temporal regional cerebral blood flow ratio also predicted rate of decline of specific memory measures on the California Verbal Learning Test. Neither parietal nor frontal ratios predicted rate of cognitive decline. Dorsolateral frontal hypoperfusion was associated with the emergence of perseverative behaviors over time. Age, prior dementia duration, estimated prior rate of decline, and initial severity did not predict rate of cognitive decline. Conclusion: Results suggest that regional perfusion on single photon emission computed tomography may predict cognitive decline in Alzheimer's disease better than these demographic and course variables.

This study compared the effect of weight loss on lipoprotein and glucose metabolism in 15 healthy, obese (body mass index [BMI], 30.9+/-2.4 kg/m(2)), older (60+/-9 years) men with LDL pattern B and in 25 men of comparable age and BMI with LDL pattern A (LDL peak particle size greater than or equal to 260 Angstrom). At baseline, men with LDL pattern B had higher TG and lower apolipoprotein (ape) A-I, HDL-C, and HDL(2)-C levels (P<.001) than men with LDL pattern A, while the total cholesterol and LDL cholesterol levels and fasting and 2-hour postprandial glucose and insulin levels did not differ between groups. With weight loss (10.1+/-3.6 kg) there were significant decreases in 2-hour postprandial glucose and insulin levels in men with LDL patterns B and A (P<.05). However, the change in plasma TG, HDL-C, HDL,-C, and apoA-I levels with weight loss differed between groups. In men with LDL pattern A, plasma TG levels decreased by 15% (P<.001) compared with a 34% (P<.001) decrease in LDL pattern B (two-factor ANOVA, P<.01). Plasma HDL-C concentrations increased by 0.16 mmol/L, (P<.001) in the men with LDL pattern A but by only 0.07 mmol/L in the men with LDL pattern B (two-factor ANOVA, P<.05). After weight loss, only 5 of the 15 men with LDL pattern B had HDL-C levels above 0.90 mmol/L (35 mg/dL), whereas 22 of 25 men with LDL pattern A had HDL-C levels above 0.90 mmol/L (chi(2)=18, P<.0001). Furthermore, with weight loss, 11 of the 15 men with LDL pattern B increased their LDL peak particle diameter; 7 converted to intermediate LDL pattern, and 4 converted to LDL pattern A. By comparison, there were no significant changes in weight, lipoprotein, or apolipoprotein concentrations at 1-year follow-up in 12 metabolic control subjects. Thus, despite significant reductions in weight and body fat and concomitant decreases in plasma TG and insulin levels, HDL-C and HDL(2) subspecies levels remain low in men with LDL pattern B.

The parameterization accounts for the competition between different aerosol types as cloud condensation nuclei, and the dependence of the competition on the number concentration, composition and size distribution of each aerosol type. Comparisons with detailed numerical solutions indicate typical differences of 50% and 20% for the number fraction and mass fraction, respectively of aerosols activated for each type.
