This code computes the Schur decomposition of a complex Hessenberg matrix. Together with existing ScaLAPACK routines, the eigenvalues of dense complex matrices can be directly computed using a parallel QR algorithm. This parallel complex Schur decomposition routine was developed to fill a void in the ScaLAPACK library and was based on the parallel real Schur decomposition routine already in ScaLAPACK. The real-arithmetic version was appropriately modified to make it work with complex arithmetic and implement a complex multiple bulge QR algorithm. This also required the development of new auxiliary routines that perform essential operations for the complex Schur decomposition, and that will provide additional linear algebra computation capability to the parallel numerical library community.

The peptide chain is well defined except in the N- and C-terminal areas. The structure of the protein reveals the presence of three helical fragments, a small beta-sheet and several turns, with the [Fe4S4] cluster being located close to a surface patch containing several well conserved aromatic residues. The protein fold is very similar to the structures of other known HiPIPs, especially in the region proximal to the [Fe4S4] cluster, while the largest differences are observed on the opposite side of the protein, which is rich in positive charges and has no sequential homology to other HiPIP families.

Because of their mixed bonding, they are often lighter, stronger, stiffer, and more corrosion-resistant than ordinary metals, particularly at high temperatures. Yet their uses are limited because they are usually brittle at room temperature (RT), making them difficult to fabricate and vulnerable to fracture. These materials hold great promise to improve efficiency in the transportation, electric power generation, and chemical process industries; however, persistent problems with low ductility and poor fracture toughness have severely limited their use in engineering systems. This article presents an overview of the progress in improving the RT ductility and fracture toughness of intermetallic compounds and describes prospects for their near-term engineering use.

These membranes exhibit a dense structure with macrovoids distributed asymmetrically throughout the cross-section. A stress-strain study demonstrated that the Young's modulus (1.421 GPa) and strain at break (7.6 %) of the new PANI asymmetric membranes prepared from hexane are approximately 12 and 4 times higher, respectively, than the values reported previously for the PANI integrally skinned asymmetric membranes (ISAMs) (123 MPa Young's modulus and 1.8 % strain at break). Furthermore, monolithic electrochemical actuators based on a single PANI asymmetric membrane were constructed, and a bending movement of up to 20 Hz was experimentally recorded in a hydrochloric acid aqueous solution. A lifetime of over 329 500 cycles was determined for these actuators at a +/-2degrees angular displacement (5 Hz). The lifetime is limited by a bending fatigue that creates a transversal crack on the PANI membrane at the air-water interface. Control over the actuator movement is also manifested by the linear dependences of the bending angle on the charge and of the angular velocity on the current. These relationships are independent of both the kind of applied electric signal and the frequency used. C1 Los Alamos Natl Lab, Biosci Div, Los Alamos, NM 87545 USA.

The RPM is a technique for analyzing solute addition data in which whole stream uptake (mgm(-2) d(-1)) is determined from the longitudinal pattern in plateau tracer concentrations. At one location, a time series of samples are collected that define the 'rising limb' of the solute breakthrough curve. The y-intercept estimated by regressing a measure of reactive tracer availability (e.g. NO3-N-15:Cl ratio) and the percentage of tracer that has resided within, and returned from, the transient storage zone (i.e. hyporheic zone) was used to predict channel-specific NO3 uptake rates. Uptake within the transient storage zone of stream-derived material is calculated by difference. Several numerical steps are developed that link uptake rate estimates to first-order reaction rate constants (lambdac and lambdas, min(-1)) more commonly used to describe solute behavior in one-dimensional transport models. The RPM was used to analyze the results of 2 stable isotope additions performed in Snake Den Branch, a small headwater stream in western North Carolina, USA. Channel-specific uptake rates (U-C) ranged from 10.6 to 23.0 ing NO3-N m(-2) d(-1) and slightly exceeded uptake in the transient storage zone (U-S), which varied from 10. 1 to 18.2 mg NO3-N m(-2) d(-1). Uptake within the transient storage zone accounted for 44-49% of the total uptake. lambdac and lambdas estimates ranged from 0.023 to 0.034 min(-1) and 0.011 to 0.024 min(-1), respectively. These processing rates correspond to solute residence times of 30-44 min and 41-90 min in the channel and storage zones, respectively. Finally, we assess the sensitivity of our approach to variation in the subsurface uptake coefficient and differing proportions of uptake occurring within the hyporheic zone. (C) 2003 Elsevier Ltd.

The correlation of Lodewyckx and Vansant [AIHAJ 61:501-505 (2000)] for mass transfer coefficients for organic vapor adsorption onto activated carbon was tested with additional data from three sources. It was then extended to better describe all the data, including that for gases. The additional parameter that accomplished this was the square root of molar equilibrium capacity of the vapor or gas on the carbon. This change, along with skew corrections when appropriate, resulted in better correlations with all experimental rate coefficients.

Reverse transcription was performed on total RNA samples extracted from kidney, normal breast, and breast tumor. Then, fluorophor-labeled cDNAs were synthesized by using random hexamers as primers for analysis by capillary gel electrophoresis. By overlaying the electropherograms and by performing multivariate analysis, we found that the RNA patterns were significantly different among the tissue samples. The protocol utilizes only submicroliter volumes of PCR products and is compatible with multiple capillary DNA sequencing instruments. These CE-based RNA patterns provide an alternative to RNA microarrays for expression profiling for understanding the molecular basis of disease.

A microdialysis junction is employed as the interface for on-line combination of capillary isoelectric focusing (CIEF) with transient capillary isotachophoresis/zone electrophoresis (CITP/CZE) in an integrated platform. Besides the excellent resolving power afforded by both CIEF and CZE separations, the electrokinetic focusing/stacking effects of CIEF and CLIP greatly enhance the dynamic range and detection sensitivity of MS for protein identification. The constructed multidimensional separation/concentration platform is demonstrated for the analysis of Shewanella oneidensis proteome, which has considerable implications toward the bioremediation of environmental pollutants. The electrokinetic-based platform offers the overall peak capacity. comparable to those obtained using multidimensional chromatography systems, but with a much shorter run time and no need for column regeneration. Most importantly, a total of 1174 unique proteins, corresponding to 26.5% proteome coverage, are identified from the cytosolic fraction of S. oneidensis, while requiring <500 ng of proteolytic digest loaded in the CIEF capillary. The ultrasensitive capabilities of electrokinetic-based proteome approach are attributed to the concentration effect in CIEF, the electrokinetic stacking of CITP, the nanoscale peak volume in CZE, the "accurate mass tag" strategy for protein/peptide identification, and the high-sensitivity, high-resolution, and high-mass measurement accuracy of FTICR-MS.

Samples were deposited in microliter volumes on thin silicon nitride windows and dried. The energy loss of the alpha-particles after traversing the sample was converted to a mass using tabulated alpha-particle stopping powers. The measurement was absolute, independent of biomolecule species, and no standards were needed for quantitation. The method has a dynamic range of 0.1-100 mug for deposits of diameter 1-2 mm. The precision varies from similar to20 % at 100 ng to a few percent at 5-100 mug. The silicon nitride windows allow multimodal analysis of the same quantified sample, including PIXE probing of elemental abundances, molecular identification by mass spectrometry, and isotopic quantitation of interactions. The method was used with accelerator mass spectrometry to quantify specific activities of microgram quantities of C-14-labeled proteins.

Deposition of a MPN film was obtained in a 2-m, 530-mum-i.d. deactivated silica capillary using gravity to force the solution containing the MPN material through the capillary. By SEM analysis, the average film thickness was determined to be 60.7 nm. The retention behavior for the dodecanethiol MPN column was studied using four compound classes (alkanes, alcohols, aromatics, ketones), and retention orders were objectively compared to a commercially available column (AT-1, 100-nm film thickness). Separation of an eight-component mixture was performed using both isothermal and temperature-programming methods with the dodecanethiol MPN phase and compared to an isothermal separation with the AT-1 phase. The AT-1 phase separation had an efficiency, N, of 6200 (k' = 0.33) while the dodecanethiol MPN phase separation had an efficiency, N, of 5700 (k' = 0.21) for the same analyte, octane. The reduced plate height, h, for octane was found to be less than 1 at the optimum linear flow velocity, indicating the MPN column operated near the optimum possible performance level. Robustness of the MPN phase is also discussed with consistent erformance observed over several months. Overall, MPNs appear promising as a stationary-phase material for GC and as an experimental platform to study their thermodynamic and mass-transfer properties.

In addition, HO2 is found in droplets and surface water as a result of photochemical formation and gas-phase scavenging. We describe a quantitative method for determining trace concentrations of HO2 radicals that exploits the chemiluminescence produced upon reaction with a synthetic analogue of luciferin from the crustacean Cypridina. The technique is linear at least up to 1 muM HO2(aq) and has a minimum detection limit of 0.1 nM. A unique feature of this analysis is a calibration method using stable aqueous HO2 standards produced in submicromolar concentrations using Co-60 gamma-radiolysis. The advantage of this method in comparison to others in consideration of field deployment is its simplicity, low cost, and minimal size and power requirements. One intended application of this technique is the measurement of atmospheric HO2 radicals following collection into aqueous solution.

Although nothing is known about anaerobic methane oxidation at the molecular level, the evolutionary relationship between methane-oxidizing archaea (MOA) and methanogenic archaea raises the possibility that MOA have co-opted key elements of the methanogenic pathway, reversing many of its steps to oxidize methane anaerobically. In order to explore this hypothesis, the existence and genomic conservation of methyl coenzyme M reductase (MCR), the enzyme catalyzing the terminal step in methanogenesis, was studied in ANME-1 and ANME-2 archaea isolated from various marine environments. Clone libraries targeting a conserved region of the alpha subunit of MCR (mcrA) were generated and compared from environmental samples, laboratory-incubated microcosms, and fosmid libraries. Four out of five novel mcrA types identified from these sources were associated with ANME-1 or ANME-2 group members. Assignment of mcrA types to specific phylogenetic groups was based on environmental clone recoveries, selective enrichment of specific MOA and mcrA types in a microcosm, phylogenetic congruence between mcrA and small-subunit rRNA tree topologies, and genomic context derived from fosmid sequences. Analysis of the ANME-1 and ANME-2 mcrA sequences suggested the potential for catalytic activity based on conservation of active-site amino acids. These results provide a basis for identifying methanotrophic archaea with mcrA sequences and define a functional genomic link between methanogenic and methanotrophic archaea.

Because detectors cannot be fully shielded from such energy sources, it is necessary to understand the effect of a photon or cosmic-ray particle being absorbed. The resulting signal (known as a glitch) can then be removed from raw data. We present measurements using an Americium-241 gamma radiation source to irradiate a prototype bolometer for the High Frequency Instrument in the Planck Surveyor satellite. Our measurements showed no variation in response depending on where the radiation was absorbed, demonstrating that the bolometer absorber and thermistor thermalize quickly. The bolometer has previously been fully characterized both electrically and optically. We find that using optically measured time constants underestimates the time taken for the detector to recover from a radiation absorption event. However, a full thermal model for the bolometer, with parameters taken from electrical and optical measurements, provides accurate time constants. Slight deviations from the model were seen at high energies; these can be accounted for by use of an extended model. (C) 2003 Optical Society of America.

The scattered temporal transmitted and reflected optical signals are measured experimentally with a streak camera for tissue phantoms irradiated with a short-pulse laser source. A parametric study involving different scattering and absorption coefficients of tissue phantoms and inhomogeneities, as well as the detector positions and orientations, is performed.

Previous studies suggest that this variability may be due to the parallel and antiparallel orientation of neighboring collagen fibrils. We applied high-resolution second-harmonic generation microscopy to confirm this hypothesis. Studies in which the focal spot diameter was varied from similar to1 to similar to6 mum strongly suggest that regions in which collagen fibrils have the same orientation in rat tail tendon are likely to be less than similar to1 mum in diameter. These measurements required accurate determination of the focal spot size achieved by use of different microscope objectives; we developed a technique that uses second-harmonic generation in a quartz reference to measure the focal spot diameter directly. We also used the quartz reference to determine a lower limit (d(XXX) > 0.4 pm/V) for the magnitude of the second-order nonlinear susceptibility in collagen. (C) 2003 Optical Society of America.

Fabry-Perot interference fringes and attenuation of a reflected HeNe laser beam are used to measure the length of VAA-MWNT throughout the first 3-8 mum of growth yielding in situ measurements of growth rates and kinetics and the capability to observe the onset and termination of growth. VAA-MWNT growth is characterized between 565 and 750 degreesC on Si substrates with evaporated Al/Fe/Mo multilayer catalysts and acetylene feedstock. Nanotube lengths were controlled by rapid evacuation of the chamber at predetermined reflectivities, and it was demonstrated that growth can be restarted at later times. The extinction coefficients of the VAA-MWNT were studied and correlated with nanotube wall structure. Growth rates for VAA-MWNT are found to vary depending on the catalyst preparation, temperature, and time. Both the highest growth rates (0.3 mum/s) and the tallest VAA-MWNT (0.75 mm long) were achieved at 730 degreesC. (C) 2003 American Institute of Physics.

Microstructure and remanent magnetization images were studied by an optical microscope and a SQUID microscope, respectively. The HAZ, in which only the face-centered-cubic austenite phase exists, could be visualized by the SQUID microscope. It was also found that the SQUID images were consistent with the results from the microstructural analysis. It was concluded that a simple SQUID measurement may serve as an effective method for a nondestructive evaluation of ferromagnetic steel phases by correlating remanent magnetization images to microstructural characteristics.

If the amount of hemoglobin in solution varies, the size of the histidine signal can vary depending on changes in either the pH or hemoglobin concentration. Multivariate calibration models developed using the NIR spectra collected from blood at a single hemoglobin concentration are shown to predict data from different hemoglobin levels with a bias and slope. A simple, scalar path length correction of the spectral data does not correct this problem. However, global partial least-square (PLS) models built with data encompassing a range of hemoglobin concentration have a cross-validated standard error of prediction (CVSEP) similar to the CVSEP of data obtained from a single hemoglobin level. It will be shown that the prediction of pH of an unknown sample using a global PLS model requires that the unknown have a hemoglobin concentration failing within the range encompassed by the global model. An alternative method for correcting the predicted pH for hemoglobin levels is also presented. The alternative method updates the single-hemoglobin-level models with slope and intercept estimates from the pH predictions of data collected at alternate hemoglobin levels. The slope and intercept correction method gave SEP values averaging to 0.034 pH units. Since both methods require some knowledge of the hemoglobin concentration in order for a pH prediction to be made, a model for hemoglobin concentration is developed using spectral data and is used for pH correction.

Eight ponds were sampled, including four on the Savannah River Site (SRS) that had been used to cool effluent from nuclear reactors. All of the ponds were man-made, and the potential times since establishment of the copepod populations ranged from 10-70yr. Skistodiaptomus mississippiensis is nearly unknown from natural habitats of the area, but high genetic diversity within and among populations in the man-made ponds suggests that the species colonized from local sources. Haplotypes were not randomly distributed among ponds or between drainages. Results of a nested cladistic analysis revealed that primary routes of colonization were most likely due to contiguous range expansion of haplotypes predominant within the area. Among abandoned cooling ponds of the SRS, the larger ponds showed greater proportions of haplotypes confined to the Savannah River drainage. These haplotypes were poorly represented in the two smaller ponds, where more extreme temperatures or extensive flushing may have opened the habitats for more extensive colonization by haplotypes predominantly occurring in the Edisto River drainage.

In vitro analysis of the intergenic region between the apo(a) and plasminogen genes revealed the presence of a putative apo(a) transcription control region (ACR) approximately 20 kb upstream of the apo(a) gene that significantly increases the minimal promoter activity of the human apo(a) gene. Methods and Results-To examine the function of the ACR in its natural genomic context, we used the Cre-loxP recombination system to generate 2 nearly identical apo(a)-yeast artificial chromosome transgenic mouse lines that possess a single integration site for the human apo(a) transgene in the mouse genome but differ by the presence or absence of the ACR enhancer. Analysis of the 2 groups of animals revealed that the deletion of the ACR was associated with 30% reduction in plasma and mRNA apo(a) levels. Apo(a)-yeast artificial chromosome transgenic mice with and without the ACR sequence were similar in all other aspects of apo(a) regulation, including liver-specific apo(a) expression and alteration in expression levels in response to sexual maturation and a high-fat diet. Conclusions-This study provides the first experimental in vivo evidence for a functional role of the ACR enhancer in determining levels of apo(a) expression.

The time baseline we attain this way ranges from a few months to up to 50 yr. In contrast to monitoring programs, where relatively few quasars are photometrically measured over shorter time periods, we use existing databases to extend this baseline as much as possible, at the cost of sampling per quasar. Our method, however, can easily be extended to much larger samples. We construct variability structure functions and compare these with the literature and model functions. From our modeling, we conclude that ( 1) quasars are more variable toward shorter wavelengths, ( 2) their variability is consistent with an exponentially decaying light curve with a typical timescale of similar to 2 yr, and ( 3) these outbursts occur on typical timescales of similar to 200 yr. With the upcoming first data release of the SDSS, a much larger quasar sample can be used to put these conclusions on a more secure footing. C1 Univ Calif Davis, Dept Phys, Davis, CA 95616 USA.

TI Simple hydrodynamical Simulations of the Circumnuclear Disk SO ASTRONOMISCHE NACHRICHTEN LA English DT Article DE GMC; simulation; Sgr A AB The "circumnuclear disk" (CND) is a dense, clumpy, asymmetric ring-like feature centered on Sgr A*. The outer edge of the CND is not distinct but the disk extends for more than 7 pc; the distinct inner edge, at a radius of similar or equal to 1.5 pc, surrounds the "mini-spiral" of the HII region, Sgr A West. We present simple 3D hydrodynamical models of the formation and evolution of the CND from multiple self-gravitating infalling clouds and compare the results with recent observations. We assume the clouds are initially Bonner-Ebert spheres, in equilibrium with a hot confining inter-cloud medium. We include the gravitational potential due to the point-mass of Sgr A* as well as the extended mass distribution of the underlying stellar population. We also include the effects of the ram pressure due to the stellar winds from the central cluster of early-type stars. A single spherically symmetric cloud cannot reproduce the clumpy morphology of the CND; multiple clouds on diverse trajectories are required so that cloud-cloud collisions can circularize the clouds' orbits while maintaining a clumpy morphology. Collisions also serve to compress the clouds, delaying tidal disruption while potentially hastening gravitational collapse. Low density clumps are disrupted before reaching the inner CND radius, forming short-lived arcs. The outer parts of more massive clumps get tidally stripped, forming long-lived low-density wide-angle arcs, while their cores potentially undergo gravitational collapse. The fine balance between resisting tidal disruption and preventing gravitational collapse implies that most if not all clumps are not stable for much more than an orbit. Thus, in order for the CND to be a long-lived clumpy object, it must be continually fed by additional in-falling clouds. Clouds that survive to small radii are likely to be the sites of present or future star formation. However, within a few parsecs of Sgr A*, the stellar winds decelerate any in-falling cloud so that the wind-cloud interface becomes Rayleigh-Taylor unstable, potentially disrupting the cloud and inhibiting star formation.

Taking advantage of the low UV continuum and broad emission-line fluxes, we have determined that the deepest UV absorption component covers at least a portion of the inner, high-ionization narrow-line region (NLR). We find nonunity covering factors in the cores of several kinematic components, which increase the column density measurements of N v and C iv by factors of 1.2 - 1.9 over the full-covering case; however, the revised columns have only a minor effect on the parameters derived from our photoionization models. For the first time, we have simultaneous N v and C iv columns for component 1 ( at - 1040 km s(-1)) and find that this component cannot be an X-ray warm absorber, contrary to our previous claim based on nonsimultaneous observations. We find that models of the absorbers based on solar abundances severely overpredict the O vi columns previously obtained with the Far Ultraviolet Spectroscopic Explorer and present arguments that this is not likely due to variability. However, models that include either enhanced nitrogen ( twice solar) or dust, with strong depletion of carbon in either case, are successful in matching all of the observed ionic columns. These models result in substantially lower ionization parameters and total column densities compared to dust-free solar-abundance models and produce little O VII or O VIII, indicating that none of the UV absorbers are X-ray warm absorbers.

By extending our modeling efforts to a three-dimensional hydrodynamics treatment, we are able to investigate the effects of explosion asymmetries on mixing and gamma-ray line emergence in supernovae. A series of initial explosion conditions are implemented, including jetlike and equatorial asymmetries of varying degree. For comparison, symmetric explosion models are also calculated. A series of time slices from the explosion evolution are further analyzed using a three-dimensional Monte Carlo gamma-ray transport code. The emergent hard X- and gamma-ray spectra are calculated as a function of both viewing angle and time, including trends in the gamma-ray line profiles. We find significant differences in the velocity distribution of radioactive nickel between the symmetric and asymmetric explosion models. The effects of this spatial distribution change are reflected in the overall high-energy spectrum, as well as in the individual gamma-ray line profiles.

Recent submillimeter and millimeter imaging of these systems resolves the circumstellar dust and reveals complex structures, often in the form of rings with azimuthal nonaxisymmetric variations. This structure might well be due to the presence of embedded brown dwarfs or planets. We have carried out deep adaptive optics imaging of two nearby stars with such asymmetric dust: epsilon Eri and Vega. Ten and seven candidate companions were seen in and near the dust rings of epsilon Eri and Vega, respectively, but second-epoch proper motion measurements indicate that all are background objects. Around these two stars we can thus exclude planetary companions at spatial scales comparable to the radius of the dust structures to a level of M-K = 24, corresponding to 5 Jupiter masses, for epsilon Eri, and M-K = 19-21, corresponding to 6 - 8 Jupiter masses, for Vega.

However, there is a good chance that also sequences with lower sequence identity have their structural components represented in structural databases. To this end, we present a novel fragment-based method using sets of structurally similar local fragments of proteins. The approach differs from other fragment-based methods that use only single backbone fragments. Instead, we use a library of groups containing sets of sequence fragments with geometrically similar local structures and extract sequence related properties to assign these specific geometrical conformations to target sequences. We test the ability of the approach to recognize correct SCOP folds for 273 sequences from the 49 most popular folds. 49% of these sequences have the correct fold as their top prediction, while 82% have the correct fold in one of the top five predictions. Moreover, the approach shows no performance reduction on a subset of sequence targets with less than 10% sequence identity to any protein used to build the library.

Although they produce visually convincing results, all of the methodologies that have been employed are prone to produce spurious decompositions. Examples of potential failures are given. A branch-and-bound algorithm for submovement extraction, capable of global nonlinear minimization (and hence capable of avoiding spurious decompositions), is developed and demonstrated.

The bent microneedle was found to have the highest fluid carrying capacity of 0.082 ml/sec at 138 kPa with a Reynolds number of 738. A microneedle with a built in microfilter had a flow rate of 0.07 ml/sec. Although the throughput of these microneedles is low they compare favorably with other microneedle designs. Laminar flow models were found to accurately predict the flow behavior through the microneedles. All computational modeling was performed with the CFDRC CFD-ACE + suite of software tools.

This design typically consists of an irregular grid of time points on which repeated measurements are taken for a number of subjects. We introduce shrinkage estimates for the functional principal component scores that serve as the random effects in the model. Scatterplot smoothing methods are used to estimate the mean function and covariance surface of this model. We propose improved estimation in the neighborhood of and at the diagonal of the covariance surface, where the measurement errors are reflected. The presence of additive measurement errors motivates shrinkage estimates for the functional principal component scores. Shrinkage estimates are developed through best linear prediction and in a generalized version, aiming at minimizing one-curve-leave-out prediction error. The estimation of individual trajectories combines data obtained from that individual as well as all other individuals. We apply our methods to new data regarding the analysis of the level of C-14-folate in plasma as a function of time since dosing of healthy adults with a small tracer dose of C-14-folic acid. A time transformation was incorporated to handle design irregularity concerning the time points on which the measurements were taken. The proposed methodology, incorporating shrinkage and data-adaptive features, is seen to be well suited for describing population kinetics of C-14-folate-specific activity and random effects, and can also be applied to other functional data analysis problems.

Though these AIMD calculations have important limitations of scale, the comparisons with the liquid solution results are satisfactory and significantly different from the radial distributions extracted from the data on the solid Kr/H2O clathrate hydrate phase. The calculations also produce the coordination number distribution that can be examined for metastable coordination structures suggesting possibilities for clathrate-like organization; none are seen in these results. Clathrate pictures of hydrophobic hydration are discussed, as is the quasi-chemical theory that should provide a basis for clathrate pictures. Outer shell contributions are discussed and estimated; they are positive and larger than the positive experimental hydration free energy of Kr(aq), implying that inner shell contributions must be negative and of comparable size. Clathrate-like inner shell hydration structures on a Kr atom solute are obtained for some, but not all, of the coordination number cases observed in the simulation. The structures found have a delicate stability. Inner shell coordination structures extracted from the simulation of the liquid, and then subjected to quantum chemical optimization, always decomposed. Interactions with the outer shell material are decisive in stabilizing coordination structures observed in liquid solution and in clathrate phases. The primitive quasi-chemical estimate that uses a dielectric model for the influence of the outer shell material on the inner shell equilibria gives a contribution to hydration free energy that is positive and larger than the experimental hydration free energy. The 'what are we to tell students' question about hydrophobic hydration, often answered with structural clathrate pictures, is then considered; we propose an alternative answer that is consistent with successful molecular theories of hydrophobic effects and based upon distinctive observable properties of liquid water. Considerations of parsimony, for instance Ockham's razor, then suggest that additional structural hypotheses in response to 'what are we to tell students' are not required at this stage.

With this background, the TB Structural Genomics Consortium has been formed. This international consortium is comprised of laboratories from 31 universities and institutes in 13 countries. The goal of the consortium is to determine the structures of over 400 potential drug targets from the genome of Mycobacterium tuberculosis and analyze their structures in the context of functional information. We summarize the efforts of the UCLA consortium members. Potential drug targets were selected using a variety of bioinformatics methods and screened for certain physical and species-specific properties to yield a starting group of protein targets for structure determination. Target determination methods include protein phylogenetic profiles and Rosetta Stone methods, and the use of related biochemical pathways to select genes linked to essential prokaryotic genes. Criteria imposed on target selection included potential protein solubility, protein or domain size, and targets that lack homologs in eukaryotic organisms. In addition, some protein targets were chosen that are specific to M. tuberculosis, such as PE and PPE domains. Thus far, the UCLA group has cloned 263 targets, expressed 171 proteins and purified 40 proteins, which are currently in crystallization trials. Our efforts have yielded 13 crystals and eight structures. Seven structures are summarized here. Four of the structures are secreted proteins: antigen 8513; MPT 63, which is one of the three major secreted proteins of M. tuberculosis; a thioredoxin derivative Rv2878c; and potentially secreted glutamate synthetase. We also report the structures of three proteins that are potentially essential to the survival of M. tuberculosis: a protein involved in the folate biosynthetic pathway (Rv3607c); a protein involved in the biosynthesis of vitamin B5 (Rv3602c); and a pyrophosphatase, Rv2697c. Our approach to the M. tuberculosis structural genomics project will yield information for drug design and vaccine production against tuberculosis. In addition, this study will provide further insights into the mechanisms of mycobacterial pathogenesis. (C) 2003 Elsevier Science B.V. All rights reserved.

By analyzing the IXS data based on the generalized three effective eigenmode model (GTEE), we obtain dispersion relations of the high frequency density oscillations (phonons) of lipid molecules in these bilayers. We then compare the dispersion relations of pure lipid bilayers of different chain lengths among themselves and the dispersion relations of pure lipid bilayers with those of the cholesterol containing bilayers. We also compare our experimental results with collective dynamics data generated by computer molecular dynamics (MD) simulations for dipalmitoylphosphatidylcholine (DPPC) in gel phase and DMPC in liquid crystal phase.

Such conformational changes are stochastic and often inhomogeneous, which makes it extremely difficult, if not impossible, to characterize them by ensemble-averaged experiments or by single-channel recordings of the electric current that report the open-closed events but do not specifically probe the associated conformational changes. Here, we report our studies on ion channel conformational changes using a new approach, patch-clamp fluorescence microscopy, which simultaneously combines single-molecule fluorescence spectroscopy and single-channel current recordings to probe the open-closed transitions and the conformational dynamics of individual ion channels. We demonstrate patch-clamp fluorescence microscopy by measuring gramicidin ion channel conformational changes in a lipid bilayer formed at a patch-clamp micropipette tip under a buffer solution. By measuring single-pair fluorescence resonance energy transfer and fluorescence self-quenching from dye-labeled gramicidin channels, we observed that the efficiency of single-pair fluorescence resonance energy transfer and self-quenching is widely distributed, which reflects a broad distribution of conformations. Our results strongly suggest a hitherto undetectable correlation between the multiple conformational states of the gramicidin channel and its closed and open states in a lipid bilayer.

The spectral changes were observed even after correcting for cell number and volume, ruling out these trivial explanations. Several of the changes occurred for both transformed and normal cell lines and were greater for the normal cell line. The biochemical basis of the spectral changes was estimated by fitting the cell spectra to a linear superposition of spectra for the major biochemical components of mammalian cells (DNA, RNA, protein, lipids, and glycogen). The ratios of RNA/lipid and protein/lipid increased when the cells were in the exponential phase compared to the plateau phase of growth. The fits of cell spectra to individual biochemical components also demonstrated that DNA is a relatively minor spectroscopic component as would be expected biochemically. Contrary to other reports in the literature, our data demonstrate that determining DNA content or structure using Fourier transform infrared spectroscopy data is difficult due to the relatively small amount of DNA and the overlap of DNA bands with the absorption bands of other biochemical components.

Two key unknown factors are the fate of carbon newly incorporated by photosynthesis into various pools within the ecosystem and the extent to which elevated CO2 is transferred to and sequestered in pools with long turnover times. The CO2 used for enrichment in many experiments incorporates a dual isotopic tracer, in the sense that ratios of both the stable carbon-13 (C-13) and the radioactive carbon-14 (C-14) isotopes with respect to carbon-12 are different from the corresponding ratios in atmospheric CO2. Here we review techniques for using C-13 and C-14 abundances to follow the fate of newly fixed carbon and to further our understanding of the turnover times of ecosystem carbon pools. We also discuss the application of nitrogen, oxygen, and hydrogen isotope analyses for tracing changes in the linkages between carbon, nitrogen, and water cycles under conditions of elevated CO2.

This approach accounts for the errors associated with reported data and how reliable the researcher believes the model to be. The optimization is conducted with a multi-objective genetic algorithm (GA) coupled with Bayesian statistics to more accurately link the limited and uncertain experimental thermodynamic data to thermodynamic models of interest. The computer program provides guidance as to which experiments are needed to enhance the reliability of the dataset and is ideally suited for parameter optimization and sensitivity analysis. Applications include the UO2-PuO2 and UO2-BeO systems. (C) 2004 Elsevier Ltd. All rights reserved. C1 Los Alamos Natl Lab, Los Alamos, NM 87545 USA.

Marker analysis of seven female and eight male S. eriocephala clones used to produce 34 fullsib families reveals that five pairs of parents are alternatively polymorphic relative to reciprocal male and female combinations for the two marker loci. A goodness-of-fit test of marker presence or absence and relationship to gender suggests that the occurrence of SCAR 354(520) is not significantly different (chi(2)=3.18, df=1, P>0.05) from the expected ratio of marker presence:absence in the male and female progenies across all five families, indicating no relationship to gender. However, the occurrence of SCAR AE08(780) differs significantly from expected (chi(2)=21.05, df=1, P<0.001) in the five families and seems to be linked to femaleness in S. eriocephala. Within a single family, 984 (n=54), both markers show a significant deviation from expected at P<0.01 (SCAR AE08(780): chi(2)=11.37, df=1; SCAR 354(520): chi(2)=9.49, df=1). These data support the hypothesis that there is an association between the markers and a locus associated with gender in two divergent species and that there may be a common sex determination mechanism in willow.

To define Myc's functional role, we generated transgenic mice expressing human c-Myc in the mouse prostate. All mice developed murine prostatic intraepithelial neoplasia followed by invasive adenocarcinoma. Microarray-based expression profiling identified a Myc prostate cancer expression signature, which included the putative human tumor suppressor NXK3.1. Human prostate tumor databases revealed modules of human genes that varied in concert with the Myc prostate cancer signature. This module includes the Pim-1 kinase, a gene known to cooperate with Myc in tumorigenesis, and defines a subset of human, "Myc-like" human cancers. This approach illustrates how genomic technologies can be applied to mouse cancer models to guide evaluation of human tumor databases. C1 Univ Calif Los Angeles, Dept Med, Los Angeles, CA 90095 USA.

The Pt supported on ceria-promoted ZrO2 catalyst was more stable than the Pt/ZrO2 catalyst under all reaction conditions. We ascribe this higher stability to the higher density of oxygen vacancies on the promoted support, which favors the cleaning mechanism of the metal particle. The increase of either the CH4 : CO2 ratio or total pressure causes a decrease in activity for both catalysts, because under either case the rate of methane decomposition becomes higher than the rate of oxygen transfer. The Pt/Ce-ZrO2 catalyst was always more stable than the Pt/ZrO2 catalyst, demonstrating the important role of the support on this reaction.

Catechol estrogen quinones (CEQ) derived from 4-hydroxyestrone (4-OHE1) and 4-hydroxyestradiol (4-OHE2) react with DNA and form depurinating N7Gua and N3Ade adducts that might be responsible for tumor initiation (Cavalieri, E. L., et al. (2000) J. Natl. Cancer Inst. Monogr. 27, 75). Current detection limits for the CEQ-derived DNA adducts by high-performance liquid chromatography with multichannel electrochemical detection are in the picomole range. To improve the limit of detection (LOD) for CEQ-derived DNA adducts, spectrophotometric monitoring was investigated. Spectroscopic studies of 4-OHE1-1-N3Ade, 4-OHE1-1-N7Gua, 4-OHE2-1-N3Ade, and 4-OHE2-1-N7Gua adduct standards were performed at 77 and 300 K. Upon laser excitation at 257 nm, the 4-OHE1- and 4-OHE2-derived N7Gua and N3Ade adducts are strongly phosphorescent at T = 77 K. No phosphorescence was observed at 300 K. Both N3Ade and N7Gua adduct types have weak phosphorescence origin bands near 383 and 385 nm, respectively. The corresponding phosphorescence lifetimes are 1.11 +/- 0.05 and 0.37 +/- 0.05 s. The LOD, based on phosphorescence measurements, is in the low femtomole range. The concentration LOD is approximately 10(-9) M, i.e., similar to that recently obtained for CEQ-derived N-acetylcysteine conjugates (Jankowiak, R., et al. (2003) Chem. Res. Toxicol. 16, 304). The LOD in capillary electrophoresis (CE) with field-amplified sample stacking and absorbance detection is about 3 x 10(-8) M. To verify whether CEQ-derived DNA adducts are formed in humans or not, tissue extracts from two breast cancer patients were analyzed by CE interfaced with room temperature absorption and low temperature (laser-excited) phosphorescence spectroscopies. For the first time, formation of CEQ-derived DNA adducts is shown in humans. For example, the level of 4-OHE1-1-N3Ade in the breast tissue extract from a patient with breast carcinoma (8.40 +/- 0.05 pmol/g of tissue) is larger by a factor of about 30 than that in the breast tissue sample from a woman without breast cancer (0.25 +/- 0.05 pmol/g of tissue). In contrast, similar amounts of 4-OHE2-1-N3Ade were observed in both types of tissue. Although more breast tissue samples from women with and without breast cancer need to be studied, these results suggest that the N3Ade adducts could serve as biomarkers to predict the risk of breast cancer.

Thermodynamic modeling has traditionally been used to study environmental contaminant migration and rarely in the examination of metal (particularly beryllium) toxicology. In this work, a chemical thermodynamic speciation code (MINTEQA2) has been used to model and understand the chemistry of beryllium in simulated human biological fluids such as intracellular, interstitial, and plasma fluids, a number of airway surface fluids for patients with lung conditions, saliva, sweat, urine, bile, gastric juice, and pancreatic fluid. The results show that predicted beryllium solubility and speciation vary markedly between each simulated biological fluid. Formation of beryllium hydroxide and/or phosphate was observed in most of the modeled fluids, and results support the postulation that beryllium absorption in the gastrointestinal tract may be limited by the formation of beryllium phosphate solids. It is also postulated that beryllium is potentially 13% less soluble in the airway surface fluid of a patient with asthma when compared to a "normal" case. The results of this work, supported by experimental validation, can aid in the understanding of beryllium toxicology. Our results can potentially be applied to assessing the feasibility of biological monitoring or chelation treatment of beryllium body burden.

The rates for these reactions have been uncertain due to discrepancies in recent measurements, as well as to a lack of a comprehensive examination of the available structure information in the compound nucleus Ne-19. We have examined the latest experimental measurements with radioactive and stable beams, and made estimates of the unmeasured Ne-19 nuclear level parameters, to generate new rates with uncertainties for these reactions. The rates are expressed as numerical values over the temperature range relevant for stellar explosions, as well as analytical expressions as functions of temperature in a format suitable for use in astrophysical simulations. Comparisons with the previous rate calculations are carried out, and the astrophysical implications are briefly discussed. C1 China Inst Atom Energy, Beijing 102413, Peoples R China.

The mucin MUC-1 was chosen as an antigen because it is abundantly expressed on epithelial cancers in an aberrantly glycosylated form, making it structurally and antigenically distinct from MUC-1 expressed on normal cells. Experimental Design: A previously constructed anti-MUC-1 phage display library from hyperimmunized mice, with 5 x 10(5) calculated variants, was screened for the selection of anti-MUC-1 scFvs. Selection criteria were high binding to a MUC-1 peptide containing 4 tandem repeats of 20 amino acids and to MUC-1-positive MCF-7 (human breast cancer) cell lysates in ELISA. Results: Six anti-MUC-1 scFv clones were selected and characterized. Nucleotide sequencing showed that four of them were full length scFv genes (variable heavy chain + variable light chain), whereas the remaining two contained either a variable heavy chain or a variable light chain alone. Their binding affinities (K-a) range between 8 x 10(7) and 10(9) m(-1). Immunohistopathology demonstrated reactivity with breast cancer cells (MCF-7 and BT20) and human breast biopsy tissue. Molecular modeling revealed high structural similarity of the anti-MUC-1 scFvs with the X-ray-determined structure of the anti-CEA scFv (MFE-23).

To increase elimination of radioactivity from the liver and body and, thus, minimize hepatic radiation dose, a peptide having a specific cathepsin B cleavage site was placed between the radiometal chelate DOTA (1,4,7,10-tetraazacyclododecane-N,N',N",N'''-tetraacetic acid) and the monoclonal antibody m170, and the comparative pharmacokinetics was evaluated in prostate cancer patients. Experimental Design: In-111-DOTA-2IT-m170 and In-111-DOTA-peptide-(GGGF)-m170, representing the same monoclonal antibody and chelate with and without the cleavable linkage, were studied in comparable groups of prostate cancer patients (17 with In-2IT-BAD-m170 and 8 with In-DOTA-peptide-m170). Pharmacokinetics over 7 days, calculated yttrium-90 radiation dosimetry, therapeutic index, and projected maximum tolerated injected yttrium-90 dose were evaluated. Results: The radioimmunoconjugates pharmacokinetics and calculated tumor and normal organ absorbed radiation dose (rads/mCi) were similar, except for a significant decrease in the mean dose to the liver (31%; P < 0.01) and lungs (31%; P < 0.01) with the DOTA-peptide immunoconjugates. Because mean tumor dose was not statistically different, this peptide linkage provided a significant increase in the therapeutic index for this tumor targeting radiopharmaceutical. If marrow support is adequate, the radiation dose historically tolerated by normal organs other than marrow would allow a 30% increase in the administered dose, resulting in a mean dose of 9500 rads to metastatic prostate cancer.

Radiolysis results when these primary and secondary (spallation) particles lose energy by Coulomb interaction with the electrons in the hydrogen and oxygen atoms of water. The results of cyclic voltammetry experiments on gold in sulphuric acid (pH 1.6) and exposed to a spallation environment were consistent with the presence of water radiolysis products. However, no changes in the An OA1-OA4 oxidation peaks or the OCIII reduction peak were observed in irradiated specimens. These findings indicate that proton irradiation and the resulting water radiolysis products do not influence passive film formation and reduction. Cyclic voltammetry experiments have also shown that a modest quantity of hydrogen bubbled into the solution had little influence on the concentration of radiolysis products that are produced during spallation near the electrochemical double layer.

In mice, Ezh2 is detected as a maternally inherited protein in the oocyte but its function at the onset of development is unknown. We have used a conditional allele of Ezh2 to deplete the oocyte of this maternal inheritance. We show that the loss of maternal Ezh2 has a long-term effect causing severe growth retardation of neonates despite 'rescue' through embryonic transcription from the paternal allele. This phenotypic effect on growth could be attributed to the asymmetric localisation of the Ezh2/Eed complex and the associated histone methylation pattern to the maternal genome, which is disrupted in Ezh2 mutant zygotes. During subsequent development, we detect distinct histone methylation patterns in the trophectoderm and the pluripotent epiblast. In the latter where Oct4 expression continues from the zygote onwards, the Ezh2/Eed complex apparently establishes a unique epigenetic state and plasticity, which probably explains why loss of Ezh2 is early embryonic lethal and obligatory for the derivation of pluripotent embryonic stem cells. By contrast, in the differentiating trophectoderm cells where Oct4 expression is progressively downregulated Ezh2/Eed complex is recruited transiently to one X chromosome in female embryos at the onset of X-inactivation. This accumulation and the associated histone methylation are also lost in Ezh2 mutants, suggesting a role in X inactivation. Thus, Ezh2 has significant and diverse roles during early development, as well as during the establishment of the first differentiated cells, the trophectoderm, and of the pluripotent epiblast cells.

For comparison purposes we also sintered pure nanocrystalline diamond compacts and micron-sized diamond-SiC composites by the infiltration method. Structure of these materials was studied by scanning electron microscopy, Raman scattering and X-ray diffraction. Diamond-SiC nanocomposites have remarkably high fracture toughness and are significantly harder than the sintered pure nanocrystalline diamond compacts. Silicon is shown to hinder graphitization of diamond. Broadening of X-ray lines is explained in terms of plastic deformations and size-effect in diamond and silicon carbide crystals.

We examined live EGFP-actin-expressing cells using confocal microscopy and saw the presence of structures strongly resembling actin. laments in the nuclei of MDA-MB-231 human mammary epithelial tumor cells. Many nuclei had more than one of these filamentous structures, some of which appeared to cross the entire nucleus. Extensive analysis, including fluorescence recovery after photobleaching ( FRAP), showed that all EGFP-actin in the nucleus is monomeric (G-actin) rather than filamentous (F-actin) and that the apparent. laments seen in the nucleus are invaginations of cytoplasmic monomeric actin. Immunolocalization of nuclear pore complex proteins shows that similar invaginations are seen in cells that are not overexpressing EGFP-actin. To determine whether there is a correlation between increased levels of invagination in the cell nuclei and the state of de-differentiation of the cell, we examined a variety of cell types, including live Xenopus embryonic cells. Cells that were highly de-differentiated, or cancerous, had an increased incidence of invagination, while cells that were differentiated had few nuclear invaginations. The nuclei of embryonic cells that were not yet differentiated underwent multiple shape changes throughout interphase, and demonstrated numerous transient invaginations of varying sizes and shapes. Although the function of these actin-filled invaginations remains speculative, their presence correlates with cells that have increased levels of nuclear activity.

Temperature and dissolved oxygen were simulated by a CE-QUAL-W2 model of Brownlee Reservoir, Idaho for a typical wet, normal, and dry hydrologic year. We compared current water quality conditions to scenarios with reduced nutrient inputs to the reservoir. White sturgeon habitat quality was modeled as a function of temperature, dissolved oxygen and, in some cases, suitability for foraging and depth. We assigned a quality index to each cell along the bottom of the reservoir. The model simulated two aspects of daily movement. Advective movement simulated the tendency for animals to move toward areas with high habitat quality, and diffusion simulated density dependent movement away from areas with high sturgeon density in areas with non-lethal habitat conditions. Mortality resulted when sturgeon were unable to leave areas with lethal temperature or dissolved oxygen conditions. Water quality was highest in winter and early spring and lowest in mid to late summer. Limiting nutrient inputs reduced the area of Brownlee Reservoir with lethal conditions for sturgeon and raised the average habitat suitability throughout the reservoir. Without movement, simulated white sturgeon survival ranged between 45 and 89%. Allowing movement raised the predicted survival of sturgeon under all conditions to above 90% as sturgeon avoided areas with low habitat quality. (C) 2003 Elsevier B.V. All rights reserved.

Biomonitoring tools are essential to assess the health of ecosystems and their component parts, including humans. While field and laboratory data are available, two critical issues to our understanding of bioavailability are often missing: 1) knowing the relationship between dose and tissue concentrations, and 2) species extrapolations. Understanding of high to low dose extrapolation is also critical. Methods to understand the importance of host factors in bioavailability of metals must assess gender, age, nutritional status, individual variability, temporal changes, and critical habitat effects. Methods to examine these variables include correlational, observational, experimental, epidemiological, and modeling studies, or a combination of these. Data gaps include developing more representative studies of human and animal populations, better analytical tools for rapid determination of metal content in the field, improved analytical characterization of metal bioavailability, and concurrent studies of different metals.

When the Li/Li(Li0.2Ni0.2Mn0.6)O-2 cell was cycled at 2.0-4.6 V, the material showed a long, irreversible plateau at 4.5-4.6 V and exhibited very high initial charge capacity of 240 mAh/g, which is much larger than a theoretical value for the reaction of Li(Li0.2+Ni0.22+Mn0.64+)O-2 --> Li-0.6(Li0.2+Ni0.24+Mn0.64+)O-2 + 0.4Li (126 mAh/g). Discharge capacity of the material gradually increased from 155 at the first cycle to 205 mAh/g at the tenth cycle and was stabilized afterward. From the ex situ X-ray study, we found that Li ions in the transition metal layer were irreversibly extracted during charging at a voltage higher than 4.5 V; the diffraction peaks corresponding to Li in the transition metal layer were hardly observed in the cathode material after extended cycling. The Li/Li(Li0.2Ni0.2Mn0.6)O-2 cell that was cycled at 2.0-4.3 V showed stable but very small capacity (69 mAh/g) and Li in the transition metal layer remained almost intact. When the cell was initially charged to 4.6 V and then cycled at 2.0-4.3 V, the cathode material showed higher capacity (114 mAh/g) than the one cycled at 2.0-4.3 V.

We present the three-dimensional structure of the hydrolysis mutant E329Q of NSF complexed with an ATP-ADP mixture at 11 Angstrom resolution by electron cryomicroscopy and single-particle averaging of NSF.alpha-SNAP.SNARE complexes. The NSF domains D1 and D2 form hexameric rings that are arranged in a double-layered barrel. Our structure is more consistent with an antiparallel orientation of the two rings rather than a parallel one. The crystal structure of the D2 domain of NSF was docked into the EM density map and shows good agreement, including details at the secondary structural level. Six protrusions corresponding to the N domain of NSF (NSF-N) emerge from the sides of the D1 domain ring. The density corresponding to alpha-SNAP and SNAREs is located on the 6-fold axis of the structure, near the NSF-N domains. The density of the N domain is weak, suggesting conformational variability in this part of NSF. C1 Brandeis Univ, Howard Hughes Med Inst, Waltham, MA 02454 USA.

The structure reveals how RAD51 proteins assemble into inactive heptameric rings and active DNA-bound filaments matching three-dimensional electron microscopy reconstructions. A polymerization motif (RAD51-PM) tethers individual subunits together to form assemblies. Subunit interactions support an allosteric 'switch' promoting ATPase activity and DNA binding roles for the N-terminal domain helix-hairpin-helix (HhH) motif. Structural and mutational results characterize RAD51 interactions with the breast cancer susceptibility protein BRCA2 in higher eukaryotes. A designed P.furiosus RAD51 mutant binds BRC repeats and forms BRCA2-dependent nuclear foci in human cells in response to gamma-irradiation-induced DNA damage, similar to human RAD51. These results show that BRCA2 repeats mimic the RAD51-PM and imply analogous RAD51 interactions with RAD52 and RAD54. Both BRCA2 and RAD54 may act as antagonists and chaperones for RAD51 filament assembly by coupling RAD51 interface exchanges with DNA binding. Together, these structural and mutational results support an interface exchange hypothesis for coordinated protein interactions in homologous recombination.

We review over 70 industrial case studies from widely available published databases, followed by an analysis of the representation of productivity benefits in energy modeling. We propose a method to include productivity benefits in the economic assessment of the potential for energy efficiency improvement. The case-study review suggests that energy efficiency investments can provide a significant boost to overall productivity within industry. If this relationship holds, the description of energy-efficient technologies as opportunities for larger productivity improvements has significant implications for conventional economic assessments. The paper explores the implications this change in perspective on the evaluation of energy-efficient technologies for a study of the iron and steel industry in the US. This examination shows that including productivity benefits explicitly in the modeling parameters would double the cost-effective potential for energy efficiency improvement, compared to an analysis excluding those benefits. We provide suggestions for future research in this important area. Published by Elsevier Science Ltd. C1 Lawrence Berkeley Natl Lab, Energy Anal Dept, Berkeley, CA 94720 USA.

When used in detailed building energy analysis programs, this correlation is expected to give more accurate calculation of roof loads, which are sensitive to outside surface convection. In our analysis, about 90% of the variance of the data was explained by a model that combined standard flat-plate equations for natural and forced convection and that took surface roughness into account. We give expressions for the convective air-film coefficient: (1) at an arbitrary point on a convex-shaped roof, for a given wind direction; (2) averaged over a strip along the wind direction; and (3) averaged over a rectangular roof for a given wind direction.

It is assumed that the pores in the reservoir are partially saturated with hydrate. A linearized model for an axisymmetric condition with a fixed well output is used in the analysis. For different reservoir temperatures and various well outputs, time evolutions of temperature and pressure profiles, as well as the gas flow rate in the hydrate zone and the gas region, are evaluated. The distance of the decomposition front from the well as a function of time is also computed. It is shown that to maintain a constant natural gas production rate, the well pressure must be decreased with time. A constant low production rate can be sustained for a long duration of time, but a high production rate demands unrealistically low pressure at the well after a relatively short production time. The simulation results show that the process of natural gas production in a hydrate reservoir is a sensitive function of reservoir temperature and hydrate zone permeability.

All three oxides were initially reduced under CO at 553 K in ethylflopolyolefin-164 solvent, and the extent of their reduction was established by monitoring CO2 evolution. The ease of reduction of alpha-Fe2O3 followed the order: UCI > NANOCAT > BASF. The Fischer-Tropsch (F-T) synthesis activities of the three reduced materials were measured at 513 K. Mossbauer and X-ray absorption fine structure (XAFS) measurements established that the initial oxides were in the alpha-Fe2O3 phase. Room-temperature XAFS together with low-temperature Mossbauer data of the quenched catalyst samples after 120 h F-T reaction suggest that all three catalysts were essentially a mixture of oxides and carbides with magnetite being the dominant phase. The observed high activity with NANOCAT and the presence of mainly (88%) magnetite phase indicate that either the oxide phase contributes as a catalyst or the minor (12%) carbide phase is extremely active for F-T synthesis. TEM images of the quenched samples remarkably showed that both unsupported nano materials, NANOCAT and BASF, avoided expected agglomeration and the micrometer-sized UCI converted into a nano material of < 10 nm under F-T reaction conditions. The narrow particle size distribution of the quenched catalysts in the nano range (similar to10-50 nm) explains the very similar activities observed with the three different-sized starting materials in the order: BASF > NANOCAT similar to UCI. The data suggest a crucial role of nanosized Fe during F-T synthesis. C1 Brookhaven Natl Lab, Energy Sci & Technol Dept, Upton, NY 11973 USA.

These separation methods simplified the fuel matrix, which allowed non-element-specific detection methods, such as mass spectrometry (MS), to be used for sulfur detection. These matrix simplification methods also enhanced the ability of element-specific detection methods, such as atomic emission detection (AED), to identify sulfur species that are present in the fuel. Separation of a model fuel mixture, as well as several representative aviation fuels, was performed using several different methods, including class-specific chemical oxidation methods that used iodine and another that used hydrogen peroxide, and a polarity-based separation that used a polar high-pressure liquid chromatography (HPLC) column. Following separation, sulfur concentration was quantified into "reactive" and "non-reactive" classes, on the basis of the ease of transformation of the species, using chemical oxidation procedures, which also relates to the tendency for the species to undergo typical hydrodesulfarization reactions with hydrogen. These two classes were broken down further, with sulfur compounds being classified as thiol, sulfides and disulfides, thiophenes, benzothiophenes, or dibenzothiophenes. The separation and identification methods proved to be robust and transferable; the results from two independent laboratories were in good agreement. Sulfur in the jet fuels tested in this study appeared mainly as thiols, sulfides, and disulfides, as determined by gas chromotography-atomic emission detection (GC-AED), following the chemical oxidation procedures. Of the refractory sulfur compounds, benzothiophenes comprised the majority, as determined by GC-MS following the (HPLC) fractionations. Thiophenes and dibenzothiophenes contributed minor amounts to the total concentration of refractory sulfur compounds. Two main components of the benzothiophene class were identified to be 2,3-dimethyl benzothiophene and 2,3,7-trimethyl benzothiophene. C1 US DOE, Natl Energy Technol Lab, Pittsburgh, PA 15236 USA.

The optimal carbonization temperature of wheat straw was found to be around 600degreesC when a burnoff of 67% was observed. The BET surface area of the activated carbon produced from the wheat straw reached as high as 300 m(2)/g. The presence of oxygen in flue gas is essential for effective adsorption of NO by activated carbon. On the contrary, water vapor inhibits the adsorption efficiency of NO. Consequently, water vapor in flue gas should be removed by drying agents before adsorption to ensure high NO adsorption efficiency. All of the NO in the flue gas was removed for more than 2 h by the activated carbons when 10% oxygen was present and the ratio of carbon weight to the flue gas flow rate (W/F) was 30 g.min/L, with a contact time of 10.2 s. All of NO was reduced to N-2 by the activated carbon at 450degreesC with a W/F ratio of 15 g.min/L and a contact time of 5.1 s. Reduction of the adsorbed NO also regenerated the activated carbon, and the regenerated activated carbon exhibited an improved NO adsorption efficiency. However, the reduction of the adsorbed NO resulted in a loss of carbon which was determined to be about 0.99% of the activated carbon per cycle of regeneration. The sufficiency of the amount of wheat straw in providing the activated carbon based on a six-person crew, such as the mission planned for Mars, has been determined. This novel approach for the control of NO, emissions is sustainable in a closed system such as the case in space travel. It is simple to operate and is functional under microgravity environment.

The teams started from several descriptions of daily lifestyles, and developed specific building characteristics as the place settings for these narratives. In addition to characterizing the physical environment, the teams also identified the forces that would be influential in making these changes. Further reflection was made on the possible unintended consequences of these changes. The energy implications of these changes were characterized with respect to magnitude and direction. While acknowledging the speculative nature of the exercise, the rationale was to broaden the discussion on future energy use by looking at future scenarios in the context of everyday life.

The historical involvement of these industries in the development and deployment of familiar loss-prevention technologies such as automobile air bags, fire prevention/suppression systems, and anti-theft devices, evidences a tradition of mediating and facilitating the use of technology to improve safety and otherwise reduce the likelihood of losses. Through an examination of the connection between risk management and energy technology, we have identified nearly 80 examples of energy-efficient and renewable energy technologies that offer loss-prevention benefits (such as improved fire safety). This article presents the business case for insurer involvement in the sustainable energy sector and documents early case studies of insurer efforts along these lines. We have mapped these opportunities onto the appropriate market segments (life, health, property, liability, business interruption, etc.). We review steps taken by 53 forward-looking insurers and reinsurers, 5 brokers, 7 insurance organizations, and 13 non-insurance organizations. We group the approaches into the categories of. information, education, and demonstration; financial incentives; specialized policies and insurance products; direct investment; customer services and inspections; codes, standards, and policies; research and development; in-house energy management; and an emerging concept informally known as "carbon insurance". While most companies have made only a modest effort to position themselves in the "green" marketplace, a few have comprehensive environmental programs that include energy efficiency and renewable energy activities.

Selective catalytic reduction of nitric oxide by ammonia over sol-gel derived CuO/gamma-Al2O3 sorbents/catalysts with different degrees of sulfation was studied in a fixed-bed packed reactor. The optimum temperature for NO reduction was found at 350degreesC for both fresh and sulfated catalysts. The properties for simultaneous removal of SO2 and NO by the sol-gel-derived CuO/gamma-Al2O3 sorbents were studied using simulated dry flue gas. The optimum operating temperature for the combined deSO(2)/deNO operations was identified at 350degreesC. At the space velocity of 5200 W and 350degreesC, a fixed-bed reactor packed with the 7.9 wt% CuO/gamma-Al2O3 sorbent prepared by the sol-gel method offers SO2 sorption capacity of 2.3 mmol g(-1) and NO conversion of 92% with a dry simulated flue gas as the feed. Under these experimental conditions, the sol-gel derived sorbents/catalysts have comparable efficiency for removal of SO2 and NOx as their commercial counterparts. The significantly higher crush strength of the sol-gel derived sorbents/catalysts make them very promising for their use in the copper oxide process for combined removal of SO2 and NOx from flue gas in a single unit operation.

The revised method uses stable Hg at low concentrations instead of Hg-203. At the reduced Hg concentrations used, NIT concentrations in livers homogenized in saline appeared to increase systematically with dilution in both bluegill sunfish (Lepomis macrochirus) and largemouth bass (Micropterus salmoides). This error suggested a binding limitation due to sulfhydryl oxidation or competition for and removal of mercury by non-MT proteins. Homogenizing tissues in trichloroacetic acid (TCA) eliminated the interference. To further evaluate the method, the protocol was tested in the laboratory and field. Metallothionein in bluegill injected with 0.6 mg/kg zinc chloride increased at a rate of 0.03 nmole MT/g liver/ h (r(2) = 0.53, p = 0.001). Linearity improved when data were corrected for protein content (r(2) = 0.74, p < 0.0001). Metallothionein levels in bluegill from a coal ash-contaminated environment were significantly increased over that of hatchery-reared sunfish (F = 20.17, p = 0.0003). The microscaled procedure minimizes concerns related to radioisotope use and waste generation while retaining the high sensitivity of the Hg-203 assay.

We develop a model based on HIJING, to which we added a ring of adjoining multiple bubbles in the central rapidity region. Our simulations were designed to be tested by the forthcoming RHIC STAR detector data for 65 GeV/n Au colliding with 65 GeV/n Au. We took into account background and resonance effects to allow a direct comparison to be made with the data. Later 100 GeV/n Au colliding with 100 GeV/n Au and LHC data could also test these ideas. We used two charged particle correlations as a sensitive method to test for bubbles. C1 Brookhaven Natl Lab, Upton, NY 11973 USA. CUNY City Coll, New York, NY 10031 USA.

Singlet ground state and finite spin-gap are confirmed by thermal-activated-type susceptibility and by a distinct peak at 16 meV in spin excitation. A triple-narrow-band structure in the spin excitation spectrum, probably due to the complex crystal structure, is observed and the possibility of a weakly interacting spin-cluster system is discussed.

At low temperature T, RH decreases linearly with magnetic field \H\ for fields larger than the field scale set by the Zeeman energy. The results suggest that the electron and hole populations are tuned by H in opposite directions via coupling of the spins to the field. As T is decreased below 5 K, the curve C(T)/T vs. T-2 shows an anomalous flattening consistent with a rapidly growing Sommerfeld parameter gamma(T).

Bending tests on several free-standing UNCD cantilevers, 0.5 mum thick, 20 mum wide and 80 mum long, yielded elastic modulus values of 916-959 GPa. The tests showed good reproducibility by repeated testing on the same cantilever and by testing several cantilevers of different lengths. The largest source of error in the method was accurate measurement of film thickness. Elastic modulus measurements performed with the novel membrane deflection experiment (MDE), developed by Espinosa and co-workers, gave results similar to those from the microcantilever-based tests. Tests were performed on UNCD specimens grown by both micro and nano wafer-seeding techniques. The elastic modulus was measured to be between 930-970 GPa for the microseeding and between 945-963 GPa for the nanoseeding technique. The MDE test also provided the fracture strength, which for UNCD was found to vary from 0.89 to 2.42 GPa for the microseeded samples and from 3.95 to 5.03 for the nanoseeded samples. The narrowing of the elastic modulus variation and major increase in fracture strength is believed to result from a reduction in surface roughness, less stress concentration, when employing the nanoseeding technique. Although both methods yielded reliable values of elastic modulus, the MDE was found to be more versatile since it yielded additional information about the structure and material properties, such as strength and initial stress state.

This method uses Raman active dye-labeled DNA gene probes and metallic nanostructures as surface-enhanced Raman scattering-active platforms. A self-assembled monolayer system composed of mercapto hexane-labeled, single-strand DNA (SH-(CH2)(6)-ssDNA/6-mercapto-1-hexanol) is formed on a silver surface. The Raman-active dye-labeled gene is hybridized with its complementary probe, which is immobilized on the silver surface. The surface-enhanced Raman gene probes in this study can be used to detect DNA targets via hybridization to complementary DNA probes. The probes do not involve the use of radioactive labels and have great potential to provide both sensitivity and selectivity. The utility of this approach is investigated.

Depending on the method of administration different PD models can be developed. Systemic (iv, sc.) MPTP administration can induce an advanced parkinsonian syndrome. However, systemic administration may require intensive animal care after neurotoxin administration, as well as repeated high doses of MPTP to avoid spontaneous recovery. Unilateral intracarotid artery (ICA) MPTP administration induces a stable hemiparkinsonian syndrome, with the advantage of allowing the animal to groom and feed itself and having a control side in the same animal. However, this unilateral syndrome lacks the bilateral characteristics of advanced PD. Bilateral ICA administration can induce a reliable bilateral syndrome but inherent is the risk of severely impairing the animals and leaving them unable to maintain themselves. This report analyzed the PD model induced by administration of unilateral ICA and subsequent intravenous injections of MPTP in rhesus monkeys. The combined method of MPTP administration induces an advanced stable parkinsonian syndrome, in which the ICA injection of MPTP initiates the parkinsonian syndrome primarily in one hemisphere and the subsequent iv. doses ( administered as needed) further deplete the dopamine (DA) system to induce a bilateral lesion in a shorter period of time, with fewer side effects. We studied the relationships between the behavioral, biochemical and histochemical changes related to the combined MPTP treatments to further characterize this model. The monkeys were categorized as presenting mild ( stage 2) or moderate ( stage 3) parkinsonism based on a parkinsonian rating scale. Postmortem biochemical analysis showed massive DA reduction equally in the caudate nucleus and putamen ipsilateral to ICA MPTP infusion, with varying degrees of DA preservation in the contralateral striatum. Differences between stage 2 and stage 3 were attributed to DA concentrations in the caudate nucleus and putamen of the contralateral hemisphere. Tyrosine hydroxylase immunohistochemistry revealed that the midbrain DA neurons of the group A8, A9, and A10 showed differential vulnerability for MPTP. This finding was similar to that observed in idiopathic PD with significant relationships between the clinical stages and cell losses in the group A9 substantia nigra pars compacta). Positron emission tomography (PET) using [F-18] 6-fluoro-L-m- tyrosine (FMT) showed that uptake (Ki) values correlated well with the biochemical data and are good predictors of DA levels in the contralateral striatal regions. Consistent with the immunohistochemical analysis, PET data also showed significant correlations with all groups of the DA cells. Here we describe an animal model that can play an important role in understanding the symptoms and therapeutic basis of PD since different severities of parkinsonian symptoms can be mimicked.

Work reported here has been concentrating on experimental studies and calculations of pellet mass loss during transfer in a guiding tube as a function of pellet parameters such as velocity and ice composition, and guiding track characteristics such as vacuum conductance, geometry, size and shape of cross-section. Results from ASDEX Upgrade and ORNL systems suggest, that centripetal loads on the pellets due to small radii bends in the systems strongly increase the erosion of pellet ice. A deleterious effect of accumulated gas due to sublimated D-2-ice blocking the tube and eroding subsequent pellets has been found. However, an efficient vacuum pumping set up for a given pellet repetition rate can significantly improve the mass conservation with respect to closed tube systems. (C) 2003 Elsevier Science B.V.

Tritium breeding, blanket energy multiplication, and neutron transmutation of these salts were assessed. Neutron activation of FLIBE and FLINABE was evaluated and site-boundary dose due to a worst-case loss of vacuum accident was estimated. Formation of F-2, TF and T-2 during power plant operation was analyzed and issues relevant to corrosion of structural materials due to the fluorine and fluoride species was assessed. Mechanism to control the corrosion of structural materials due to TF has been identified.

High purity AlN samples decreased their weights after the sintering test in Li in contact with vanadium alloy over 973 K, while those in Li not in contact with the vanadium alloy survived up to 1073 K. Nitrogen dissolution from AlN into the liquid Li and absorption of dissolved nitrogen by vanadium alloy are considered to be a corrosion mechanism. Small decreases of electrical resistance were observed after the sintering tests over 873 K because of the conductive corrosion layer on the surface caused by the nitrogen dissolution. In the cases of low purity AlN samples sintered over 973 K, large weight decreases were explained by fragile grain boundary caused by oxygen dissolution. The oxygen dissolution may also results in the resistivity decrease even at 723 K. Therefore, decrease of oxygen impurity in AlN and addition of nitrogen in liquid Li are considered to give a possible solution to the Li/AlN corrosion problem in the Li/AlN/V alloy blanket system.

However, carbon is chemically reactive in air and will react with ingress air during a Loss of Vacuum Accident and release tritium fuel that has been retained in the carbon. Tritium mobilization and carbon monoxide generation via CFC oxidation are both safety concerns. This paper discusses chemical reactivity experiments that were performed using the state-of-the-art 3-dimensional NB31 CFC produced by SNECMA and a laminar reaction gas of Ar-21 vol% O-2. Oxidation reaction rates were measured for CFC temperatures of 525, 600, 700, 800, 900, and 1000 degreesC and a 100 standard cubic centimeters per minute (sccm) Ar-O-2 flow rate. Experiments were also performed at CFC temperatures of 700 and 1000 degreesC and a 1000 sccm. Ar-O-2 flow rate. Mass spectral analyses of the exhaust reaction gas suggested that carbon monoxide was the primary reaction at the CFC surface and carbon dioxide was readily produced in the exiting reaction gas. The measured reaction rates compare well with the literature and were used to produce a CFC oxidation curve that is recommended for use in fusion safety analyses. (C) 2003 Elsevier B.V.

Key issues of the cyclic IFE operation include intense photon and ion deposition, wall thermal and hydrodynamic evolution, wall erosion and fatigue lifetime, and chamber clearing and evacuation to ensure desirable conditions prior to next target implosion. Several methods for wall protection have been proposed in the past, each having its own advantages and disadvantages. These methods include use of solid bare walls, gas-filled cavities, and liquid walls/jets. Detailed models have been developed for reflected laser light, emitted photons, neutrons, and target debris deposition and interaction with chamber components and have been implemented in the comprehensive HEIGHTS software package. The hydrodynamic response of gas-filled cavities and photon radiation transport of the deposited energy have been calculated by means of new and advanced numerical techniques for accurate shock treatment and propagation. Photon radiation transport models are developed for either the gas-filled cavity or in the evolving vapor cloud layer above the wall surface. The focus of this work is to examine the overall wall response and lifetime due to various erosion mechanisms. (C) 2003 Elsevier Science B.V. All rights reserved.

Key parameters and mechanisms are: density, moderation, and threshold reactions such as (n, 2n) and (n, 3n). Using computed time-dependent neutron intensities in the structural wall, we present a Multiscale Modeling study of pulse (1-10 Hz) irradiation in Fe, up to the level of defect microscopic characterization depending on time irradiation. Final responses of the microscopic structure after irradiation to 10(-3) dpa are reported, and the differences with a continuous irradiation, for a still low irradiation fluence, are remarked. A new code based on tight binding molecular dynamics has been developed for studying SiC; and its first applications to different temperature-dependent situations demonstrates a reliable proof of principle of the new model. An efficient Multiscale Modeling systematic approach of SiC is lacking; starting with the absence of an appropriate description of defects and its diffusion. That goal can be obtained using this TBMD accurate tool. (C) 2003 Published by Elsevier Science B.V. C1 Univ Politecn Madrid, ETSII, Inst Fus Nucl, E-28006 Madrid, Spain.

This would be a 'proof of performance' device which would follow and build upon the successes of the national spherical torus experiment (NSTX) 'proof of principle' device which has operated at PPPL since 1999. With the decontamination and decommissioning (D&D) of the tokamak fusion test reactor (TFTR) nearly completed, the TFTR test cell and facility will soon be available for a device such as NSST. By utilizing the TFTR test cell, NSST can be constructed for a relatively low cost on a short time scale. In addition, while furthering spherical torus (ST) research, this device could achieve modest fusion power gain for short pulse lengths, a significant step toward future large burning plasma devices now under discussion in the fusion community. The selected design point is Q = 2 at HH = 1.4, P(fusion) = 60 MW, 5-s pulse, with R(0) = 1.5 in, A = 1.6, I(p) = 10 MA, B(t) = 2.6 T, CS flux = 16 weber.

Due to the short distance of the divertor from the X-point, the connection lengths are short and the scrape off layer thickness is small. A relatively high peak heat flux of 25 MW/m(2) is expected on the divertor. The FIRE divertor engineering design is based on the design approaches developed for international thermonuclear experimental reactor (ITER). The geometry of the FIRE divertor consists of water cooled copper fingers and a tungsten brush armor as plasma facing material. The divertor assembly consists of modular units for remote handling. A 316 stainless steel back plate is used for support and manifolding. The backing plate is joined to the copper fingers by pins. The coolant channel diameter is 8 mm at a pitch of 14 mm. The total power flow to the outer divertor is 35 MW. Water at an inlet temperature of 30 degreesC, 1.5 MPa and a flow velocity of 10 m/s is used with two channels in series. A margin of approximate to 1.6 is obtained on the critical heat flux. A three dimensional thermal stress finite element (FE) analysis of this geometry was performed. Thermal hydraulic correlations derived for ITER were used to perform the thermal analysis. Design changes were implemented to reduce the stresses and temperatures to acceptable levels.

However, in some cases, fast particles have been observed, which locally increased the power flux density, leading to damage of these PFCs and other inner vessel components. Three different examples for irreversible component damage, such as component melting and water leaks, are described involving runaway and supra-thermal particle strikes. In view of the capability for TS to handle larger input powers and to control the particles over long pulse durations, inner vessel components have been completely redesigned. The improved design concepts retained for the CIEL upgrade and preliminary results in the new configuration are presented. (C) 2003 Elsevier Science B.V. All rights reserved.

Chief among these is the addition of the fifth and sixth I MW class gyrotrons, increasing the power available for auxiliary heating and current drive by nearly 60%. These tubes use artificially grown diamond r.f. output windows to obtain high power with long pulse capability. The beams from these tubes are nearly Gaussian, facilitating coupling to the waveguide. A new fully articulating dual launcher capable of high speed spatial scanning has been designed and tested. The launcher has two axis independent steering for each waveguide. The mirrors can be rotated at up to 100degrees/s. A new feedback system linking the DIII-D Plasma Control System (PCs) with the gyrotron beam voltage waveform generators permits real-time feedback control of some plasma properties such as electron temperature. The PCs can use a variety of plasma monitors to generate its control signal, including electron cyclotron emission and Mirnov probes. Electron cyclotron heating and electron cyclotron current drive were used during this year's DIII-D experimental campaign to control electron temperature, density, and q profiles, induce an ELM-free H-mode, and suppress the m = 2/n = I neoclassical tearing mode. The new capabilities have expanded the role of EC systems in tokamak plasma control. (C) 2003 Elsevier Science B.V. All rights reserved. C1 Gen Atom Co, San Diego, CA 92186 USA.

In a high performance AT, accurate regulation of the plasma boundary, internal profiles, pumping, fueling, and heating must be well coordinated with MHD control action to stabilize such instabilities as tearing modes and resistive wall modes. Sophisticated monitors of the operational regime must provide detection of off-normal conditions and trigger appropriate safety responses with acceptable levels of reliability. Many of these capabilities are presently implemented in the DIII-D plasma control system (PCs), and are now in frequent or routine operational use. The present work describes recent development, implementation, and operational experience with AT regime control elements for equilibrium control, MHD suppression, and off-normal event detection and response.

The possibility of using SiC-based power-MOSFET depends on operational loss reduction and circuit configuration simplification of the high current AC/DC converter system. Concerning the operational loss reduction, the lower on-state resistance of SiC-based power-MOSFET can decrease the conduction loss of switching unit, and it means that the temperature rise of switching unit in operation period is lowered. Therefore, the auxiliary cooling equipment for AC/DC converter will be minimized. The higher operational temperature of SiC-based power-MOSFET will allow also the cooling capacity minimization. As many parallel connected power-MOSFET elements are required for high current operation, the parallel connected elements should be cooled down to liquid nitrogen temperature for on-state resistance reduction.

Scoville, R.J. La Haye, Nucl. Fusion 43 (4) (2003) 250-257] and resistive wall modes (RWM) [A.M. Garofab, R.J. La Haye, J.T. Scoville, Nucl. Fusion 42 (11) (2002) 1335-1339] and subsequent loss of confinement. They can also cause errors in magnetic measurements made by point probes near the plasma edge, error in measurements made by magnetic field sensitive diagnostics, and they violate the assumption of axisymmetry in the analysis of data. Most notably, the sources of these error fields include shifts and tilts in the coil positions from ideal, coil leads, and nearby ferromagnetic materials excited by the coils. New measurements have been made of the n = I coil-related field errors in the DIII-D plasma chamber. These measurements indicate that the errors due to the plasma shaping coil system are smaller than previously reported and no additional sources of anomalous fields were identified. Thus they fail to support the suggestion of an additional significant error field suggested by locked mode and RWM experiments. (C) 2003 Elsevier B.V. All rights reserved.

AB Over the next three years the research program of the Heavy Ion Fusion Virtual National Laboratory (HIF-VNL), a collaboration among LBNL, LLNL, and PPPL, is focused on separate scientific experiments in the injection, transport and focusing of intense heavy ion beams at currents from 100 mA to 1A. As a next major step in the HIF-VNL program, we aim for a complete "source-to-target" experiment, the Integrated Beam Experiment (IBX). By combining the experience gained in the current separate beam experiments IBX would allow the integrated scientific study of the evolution of a single heavy ion beam at high current (similar to1 A) through all sections of a possible heavy ion fusion accelerator: the injection, acceleration, compression, and beam focusing. This paper describes the main parameters and technology choices of the planned IBX experiment. IBX will accelerate singly charged potassium or argon ion beams up to 10 MeVfinal energy and a longitudinal beam compression ratio of 10, resulting in a beam current at target of more than 10 Amperes. Different accelerator cell design options are described in detail: Induction cores incorporating either room temperature pulsed focusing-magnets or superconducting magnets.

ID HEAVY-ION; DESIGN AB The "Target Fabrication Facility" (TFF) of an IFE power plant must supply about 500,000 targets per day. The targets are injected into the target chamber at a rate of 5-10 Hz and tracked precisely so the driver beams can be directed to the target. The feasibility of developing successful fabrication and injection methodologies at the low cost required for energy production (about $0.25/target, about 10(4) less than current costs) is a critical issue for inertial fusion. To help identify major cost factors and technology development needs, we have utilized a classic chemical engineering approach to the TFF. The analyses assume an "nth-of-a-kind" TFF and utilize standard industrial engineering cost factors. The results indicate that the direct drive target can be produced for about $0.16 each. Iterations are still underway, for the indirect drive target. These cost analyses assume that the process development is accomplished to allow scaling of current laboratory methods to larger sizes, while still meeting target specifications. A development program is underway at various laboratories to support this scale-up. C1 Gen Atom, San Diego, CA 92186 USA. Los Alamos Natl Lab, Los Alamos, NM 87545 USA.

ID REACTOR; SHEATH; FIELD AB A power plant based on a spheromak device using liquid walls is analyzed. We assume a spheromak configuration can be made and sustained by a steady plasma gun current, which injects particles, current and magnetic field, i.e., helicity injection, which are transported into the core region. The magnetic configuration is evaluated with an axisymmetric free-boundary equilibrium code, where the current profile is tailored to support an average beta of 10%. An injection current of 100 kA (125 MW of gun power) sustains the toroidal current of 40 MA. The magnetic flux linking the gun is 1/1000(th) of the flux in the spheromak. The geometry allows a flow of liquid, either molten salt, (flibe-Li(2)GBeF(4) or flinabe-LiNaBeF4), or liquid metal such as SnLi, which protects most of the walls and structures from damage arising from neutrons and plasma particles. The free surface between the liquid and the burning plasma is heated primarily by bremsstrahlung, line radiation, and some by neutrons. The temperature of the free surface of the liquid is calculated and then the evaporation rate is estimated from vapor-pressure data. The impurity concentration in the burning plasma, about 0.8% fluorine, is limited to that giving a 20% reduction in the fusion power. The divertor power density of 620 MW/m(2) is handled by high-speed (100 m/s) liquid jets. Calculations show the tritium breeding is adequate with enriched Li-6, and a design is given for the walls not covered by flowing liquid (similar to15% of the total). We identified a number of problem areas needing further study to make the design more self-consistent and workable, including lowering the divertor power density by expanding the flux tube size.

Examples of toxic chemicals are beryllium for magnetic fusion and fluorine for laser fusion. Therefore, chemical exposure consequences must also be addressed in fusion safety assessment. This paper provides guidance for fusion safety analysis. US Department of Energy (DOE) chemical safety assessment practices for workers and the public are reviewed. The US Environmental Protection Agency (EPA) has published some guidance on public exposure to releases of mixtures of chemicals, this guidance has been used to create an initial guideline for treating mixed radiological and toxicological releases in,fusion; for example, tritiated hazardous dust from a tokamak vacuum vessel. There is no convenient means to judge the hazard severity of exposure to mixed materials. The chemical fate of mixed material constituents must be reviewed to determine if there is a separate or combined radiological and toxicological carcinogenesis, or if other health threats exist with radiological carcinogenesis. Recommendations are made for fusion facility chemical safety evaluation and safety guidance for protecting the public from chemical releases, since such levels are not specifically identified in the DOE fusion safety standard.

AB This article summarizes the results of the safety evaluation of the Evaporation of Lithium and Vapor Extraction (EVOLVE) W-alloy first wall (FW) and blanket concept(1). We have analyzed the EVOLVE design response during a confinement bypass accident. A confinement bypass accident was chosen because, based on previous safety studies(2), this accident can produce environmental releases by breaching the primary radioactive confinement boundary of EVOLVE, which is the EVOLVE vacuum vessel (VV). As a consequence of a bypass accident, air from a room adjoining the reactor enters the plasma chamber by way of a failed VV port. This air reacts with the high temperature metals inside of the VV to release energy in the case of a lithium spill, or to mobilize radioactive material by oxidation, and then transport this material to the environment by natural convection airflow through the failed VV port. We use the MELCOR code(3) to analyze the response of EVOLVE during this accident. Based on these results, the EVOLVE concept can meet the no-evacuation dose goal set by the DOE Fusion Safety Standard(4) if the EVOLVE confinement building ventilation system is closed within two hours of the onset of this accident.

AB The 2002 Snowmass Fusion Energy Sciences Summer Study required a uniform assessment of the safety design goals for three candidate burning plasma experiments: the Fusion Ignition Research Experiment (FIRE), the IGNITOR compact tokamak, and the International Thermonuclear Experimental Reactor (ITER). The main assessment criterion was an objective judgment of each design's ability to obtain a generalized regulatory approval. A brief overview of environmental impact, safety, and health results from the uniform assessment of safety are given in this paper. As safety documentation was reviewed for each design, several issues became apparent. This paper also documents these specific issues. Each of these three designs could obtain a general regulatory approval based on their safety design practices. C1 Idoho Natl Engn & Environm Lab, Idaho Falls, ID 83415 USA.

In order to calculate accident doses to the public, we have distinguished between accidents at the target fabrication facility and accidents at other areas of the power plant. Regarding the chemical toxicity assessment, we have used the U.S. DOE regulations to determine the maximum allowable release in order to protect the public from adverse health effects. Opposite to common belief it has been found that the chemical safety requirements for these materials appear to be more stringent than the concentrations that would result in an acceptable radiological dose.

Using the calculated energies, the longer timescale behavior of He-V clusters in Fe was investigated using a kinetic Monte-Carlo (KMC) simulation technique. The FP-MD-KMC scheme provided us significant information on the thermal stability of a He-V cluster in Fe as a function of the helium-to-vacancy ratio of the cluster.

The objective of the experiment is to investigate the performance of fusion structural materials subject to temperature variation during operation. The experiment will also contribute to re-examining the available fission reactor irradiation data including temperature transient. The irradiation for the experiment was performed from July 1998 to May 1999. Some results of the Post-Irradiation Examination are now available. This paper summarizes the highlights of the experimental results and insights obtained through the experiment about the temperature variation effects on materials performance under irradiation.

AB In order to determine the contributions of different microstructural features to strength and to deformation mode, microstructure of deformed flat tensile specimens of irradiated reduced activation F82H (IEA heat) base metal (BM) and its tungsten inert-gas (TIG) weldments (weld metal and weld joint) were investigated by transmission electron microscopy (TEM), following fracture surface examination by scanning electron microscopy (SEM). After irradiation, the fracture surfaces of F82H BM and TIG weldment showed a martensitic mixed quasi-cleavage and ductile-dimple fracture. The microstructure of the deformed region of irradiated F82H BM contained dislocation channels. This suggests that dislocation channeling could be the dominant deformation mechanism in this steel, resulting in the loss of strain-hardening capacity. While, the necked region of the irradiated F82H TIG, where showed less hardening than F82H BM, showed deformation bands only. From these results, it is suggested that the pre-irradiation microstructure, especially the dislocation density, could affect the post-irradiation deformation mode.

ID SYSTEM AB The negative-ion based neutral beam injection system developed by JAERI for JT-60U has been intended to generate a 500 keV and 10 MW beam for 10 seconds with two ion sources. Technical efforts to decrease heat loads on the accelerator grids, to improve non-uniformity of the source plasma, to increase voltage holding of the accelerator, and to optimize the operational parameters have been conducted intensively. A step-down control of the filament voltage was very effective to keep the acceleration current constant during the pulse duration. To suppress degradation of voltage holding of the accelerator, protection spark gaps of similar to178 kV for each stage, its gap length is 73 mm, were confirmed to be effective. As results of these improvements, as of June 2002, the maximum injection power has reached 6.2 MW, and a pulse length has attained 10 seconds of the design value with a 2.6 MW beam.

ID HIGH-FIELD-SIDE; TECHNOLOGY; TORUS AB A compact pellet injection system that was recently developed at the Oak Ridge National Laboratory has been installed on the Madison Symmetric Torus (MST) at the University of Wisconsin and used in initial plasma fueling experiments. The system, referred to as a "pellet injector in a suitcase, "is a pipe gun device with a four-barrel capability (presently equipped with two 1.0-mm-bore barrels), and it uses a cryogenic refrigeratorfor in-situ hydrogen pellet formation (typically, D-2 pellets). This new, portable, stand-alone pellet injection system was developed to provide a flexible means of plasma fueling on a wide variety of magnetic confinement devices, with relatively low costs for installation and operation. The injector has already been used to produce useful results with pellets on MST plasmas, including significant and rapid increases (almost 100%) in the line average density, and effectively depositing fuel in the plasma core (central densities of approximate to1.4 x 10(19) m(-3)). In this paper, the injection system, its performance, and reliability will be described, and results from some initial MST pellet experiments will be highlighted.

ID FUSION PLASMAS AB The transport and net loss of cyclotron radiation for burning plasmas represented by the ITER, FIRE and IGNITOR designs are assessed using the CYTRAN radiation transport code. Although cyclotron radiation might be expected to be a bigger issue in the higher field devices (FIRE and IGNITOR), the reference operating conditions in those devices are at lower temperatures so that the relative importance is nearly constant for all three. At the reference operating conditions for each of these devices, the net energy loss from cyclotron radiation is about 10% of the alpha power, and the axial loss is typically about 15% of the local alpha power density. If the same fusion power is generated at higher temperature and lower density than the reference operating points (as may be the case in advanced confinement modes), both the net and axial loss fractions strongly increase and are more competitive with other energy transport processes. The increase is much stronger for the high field devices where the axial loss can approach the local alpha energy production rate for T(0) similar to 30 keV. However, if the temperature increases at constant density (as in a thermal excursion), cyclotron radiation loss remains an almost constant fraction of the alpha production rate. This implies that it will not make a significant contribution to thermal stabilization. However, these and other calculations of cyclotron radiation transport are sensitive to assumptions of reflection, plasma geometry and profile shapes. Therefore, the effect of cyclotron radiation on operating conditions and burn dynamics will undoubtedly be a generic issue that any burning plasma will have to address.

We find that, if such a field were to exist, appropriate choices of the spinor self-interaction would generate a rich variety of behaviors, quite different from their widely studied scalar field counterparts. We first discuss solutions that incorporate a stage of cosmic inflation and estimate the primordial spectrum of density perturbations seeded during such a stage. Inflation driven by a spinor field turns out to be unappealing as it leads to a blue spectrum of perturbations and requires considerable fine-tuning of parameters. We next find that, for simple, quartic spinor self-interactions, non-singular cyclic cosmologies exist with reasonable parameter choices. These solutions might eventually be incorporated into a successful past- and future-eternal cosmological model free of singularities. In an Appendix, we discuss the classical treatment of spinors and argue that certain quantum systems might be approximated in terms of such fields.

Mainstream SiC grains are enriched in s-process barium and show a spread in isotopic composition from solar to dominantly s-process. In the relatively coarse grain size fraction analyzed, there are large grain-to-grain variations of barium isotopic composition. Comparison of single grain data with models of nucleosynthesis in asymptotic giant branch (AGB) stars indicates that the grains most likely come from low mass carbon-rich AGB stars (1.5 to 3 solar masses) of about solar metallicity and with approximately solar initial proportions of r- and s-process isotopes. Measurements of single grains imply a wide variety of neutron-to-seed ratios, in agreement with previous measurements of strontium, zirconium and molybdenum isotopic compositions of single presolar SiC grains.

These analyses are challenging in that the grains are very small, the largest being perhaps a few microns in diameter, and contain only trace concentrations of heavy elements, generally on the order of ppm. In addition, isotopic analysis requires the suppression of isobaric interferences. We describe a unique instrument, based on resonant ionization mass spectrometry, that has successfully characterized such grains for the past several years, and report on some recent upgrades that significantly enhance the instrumental capabilities. The fundamental principles and operational details are discussed, along with illustrative results and plans for future modifications. Copyright (C) 2003 Elsevier Ltd.

Samples were prepared at six pH values in the range 3.4 to 7.8, and the bacterial functional groups responsible for the adsorption were identified under each condition. Under the experimental Cd and bacterial concentrations, the spectroscopy results indicate that Cd binds predominantly to phosphoryl ligands below pH 4.4, whereas at higher pH, adsorption to carboxyl groups becomes increasingly important. At pH 7.8, we observe the activation of an additional binding site, which we tentatively ascribe to a phosphoryl site with smaller Cd-P distance than the one that is active at lower pH conditions. XAFS spectra of several cadmium acetate, phosphate, and perchlorate solutions were measured and used as standards for fingerprinting, as well as to assess the ability of FEFF8 and FEFFIT to model carboxyl, phosphoryl, and hydration environments, respectively. The results of this XAFS study in general corroborate existing surface complexation models; however, some binding mechanism details could only be detected with the XAFS technique.

Crosswell seismic and EM data sets taken before and during CO2 flooding of an oil reservoir are inverted to produce crosswell images of the change in compressional velocity, shear velocity, and electrical conductivity during a CO2 injection pilot study. A rock-properties model is developed using measured log porosity, fluid saturations, pressure, temperature, bulk density, sonic velocity, and electrical conductivity. ne parameters of the rock-properties model are found by an L-1-norm simplex minimization of predicted and observed differences in compressional velocity and density. A separate minimization, using Archie's law, provides parameters for modeling the relations between water saturation, porosity, and electrical conductivity. The rock-properties model is used to generate relationships between changes in geophysical parameters and changes in reservoir parameters. Electrical conductivity changes are directly mapped to changes in water saturation; estimated changes in water saturation are used along with the observed changes in shear-wave velocity to predict changes in reservoir pressure. The estimation of the spatial extent and amount Of CO2 relies on first removing the effects of the water saturation and pressure changes from the observed compressional velocity changes, producing a residual compressional velocity change. This velocity change is then interpreted in terms of increases in the CO2/oil ratio. Resulting images of the CO2/oil ratio show CO2-rich zones that are well correlated to the location of injection perforations, with the size of these zones also correlating to the amount of injected CO2. The images produced by this process are better correlated to the location and amount of injected CO2 than are any of the individual images of change in geophysical parameters.

Fe(III)-reducing bacteria form Fe(II)-containing minerals such as siderite, magnetite, vivianite, and green rust using iron oxides. A psychrotolerant Fe(III)-reducing bacterium, Shewanella alga (PV-4), was used to examine the reduction and biomineralization of a poorly crystalline iron oxide, akaganeite (beta-FeOOH), in the absence of a soluble electron shuttle, anthraquinone disulphonate (AQDS), under different atmospheric compositions as well as in HCO3- buffered medium (30 to 210 mM). Iron biomineralization was also examined under different growth conditions such as incubation time, electron donors, and electron acceptors. The Fe(III)-reducing bacterium, PV-4, reduced akaganeite, Fe(III)-citrate, and Co(III)EDTA using lactate or H-2 as an electron donor. The iron biomineralization of Fe(III) oxide, akaganeite-as it undergos reduction by an iron reducing bacterium-is a complex process influenced by biogeochemical factors including microorganisms, bicarbonate buffer concentration, atmospheric composition, electron donors/ acceptors, incubation time, and Eh/pH. From this research we found that microorganisms do participate in the formation of diverse iron minerals and that microbial iron biomineralization may affect Fe and C biogeochemistry in subsurface environments.

Radiocarbon dates from three core sites constrain the timing of late Quaternary paleoenvironmental changes in the Central Andes and highlight the site-specific factors that limit the radiocarbon geochronometer. With the exception of mid-Holocene sediments, all cores are generally devoid of macrophyte fragments, thus bulk organic fractions are used to build core chronologies. Comparisons of radiocarbon results for chemically defined fractions (bulk decalcified, humate, humin) suggest that ages derived from all fractions are generally coherent in the post-13,500 yr BP time interval. In the pre-13,500 yr BP time interval, ages derived from humate extracts are significantly younger (300-7000 years) than ages from paired humin residues. Gross age incoherencies between paired humate and humin sub-fractions in pre-13,500 yr BP sediments from all core sites probably reflect the net downward migration of humates. Ages derived from bulk decalcified fractions at our shallow water (90 m) and deep water (230 m) core sites consistently fall between ages derived from humate and humin sub-fractions in the pre-13,500 yr BP interval, reflecting that the bulk decalcified fraction is predominantly a mixture of humate and humin sub-fractions. Bulk decalcified ages from the pre-13,500 yr BP interval at our intermediate depth core site (150 m) are consistently older than humate (youngest) and humin sub-fractions. This uniform, reproducible pattern can be explained by the mobilization of a relatively older organic sub-fraction during and after the re-acidification step following the alkaline treatment of the bulk sediment. The inferred existence of this 'alkali-mobile, acid-soluble' sub-fraction implies a different depositional/post-depositional history that is potentially associated with a difference in source material. While internally consistent geochronologies can be developed for the Lake Titicaca sequence using different organic fractions, mobile organic sub-fractions and fractions containing mobile sub-fractions should generally be avoided in geochronology studies. Consequently, we believe humin and/or bulk decalcified ages provide the most consistent chronologies for the post-13,500 yr BP interval, and humin ages provide the most representative ages for sedimentation prior to 13,500 yr BP interval. Using the age model derived from the deep water core site and a previously published isotope-based lake-level reconstruction, we present a qualitative record of lake level in the context of several ice-core records from the western hemisphere. We find the latest Pleistocene lake-level response to changing insolation began during or just prior to the Bolling/Allerod period. Using the isotope-based lake-level reconstruction, we also find the 85-m drop in lake level that occurred during the mid-Holocene was synchronous with an increase in the variability of ice-core delta(18)O from a nearby icecap, but was not reflected in any of the polar ice-core records recovered from the interior of Antarctica and Greenland.

The remaining attenuation between the internal tracer and degrading contaminant is attributed to degradation and the degradation rate half-life is estimated from the first-order decay equation. An analytical solution of the advection- dispersion equation was used to evaluate flow-and-transport conditions that could result in incorrect estimates of contaminant degradation rate constants. Flow-and-transport characteristics that result in overestimating degradation rates were of particular interest because the internal tracer method often used to demonstrate natural attenuation can achieve remedial objectives. The analytical solution was also used to estimate the magnitude of error associated with using the internal tracer method at an example site and to explain different degradation rates estimated using tracers with different decay rate constants.

A controlled study was conducted at the HAZMAT Spill Center at the Nevada Test Site, where the sensor was tested under a range of temperature, moisture, and trichloroethylene (TCE) concentrations. The sensor responded rapidly when exposed to TCE placed in sand, and it also responded to decreases in TCE vapor concentration when clean air was vented through the system. Variations in temperature and water vapor concentration impacted baseline chemiresistor signals, but at high TCE concentrations the sensor response was dominated by the TCE exposure. Test results showed that the detection limit of the chemiresistor to TCE vapor in the presence of fluctuating environmental variables (i.e., temperature and water vapor concentration) was on the order of 1000 parts per million by volume, which is about an order of magnitude higher than values obtained in controlled laboratory environments. Automated temperature control and preconcentration is recommended to improve the stability and sensitivity of the chemiresistor sensor. C1 Sandia Natl Labs, Tech Staff, Albuquerque, NM 87185 USA.

This study is a comparison between molecular sieve and silica gel adsorbent media used for atmospheric moisture sampling conducted in the semi-arid climate of the Idaho National Engineering and Environmental Laboratory. Water vapor was collected simultaneously using two columns containing different desiccant materials (one column containing molecular sieve and the other containing silica gel). Data collected during air sampling periods were compared With meteorological data collected, and atmospheric moisture collection efficiencies were determined. Breakthrough of atmospheric moisture past the desiccant material was suspected with both media at elevated temperatures indicating that smaller sample volumes, lower volumetric flow rates, or longer adsorbent columns should be used during summer when ambient temperatures are elevated.

This study compared exposure rates measured using electret ion chambers with gamma spectroscopic analysis results of soil samples collected at the remediated site. Exposure rate measurements were made in 1999 using electret ion chambers at the same locations that INEEL Oversight Program sampled soil in 1998 following MARSSIM protocol. The waste site was divided into nine survey units based upon site history including previous site surveys and physical boundaries. Exposure rate measurements at the remediation site compared well with exposure rate measurements made at reference background locations used for routine environmental monitoring by the State of Idaho indicating that the remedial action met cleanup criteria. A poor correlation between exposure rate measurements and Cs-137 concentrations and other discrepancies were observed during this study with respect to measurements made during the 1998 final site survey.

Single-shock compression produces substantial heating, which causes a limiting compression. Multiple-shock compression is quasi-isentropic, which achieves lower temperatures and higher densities than single shocks, and has no limiting compression. Diatomic fluids have universal behaviors under dynamic compression. Under multiple-shock compression, these fluids undergo density-driven nonmetal-metal Mott transitions, probably in the monatomic state, with common density scaling at similar to100 GPa. Under single-shock compression, these fluids have essentially the same Hugoniot in velocity space. D(2) undergoes temperature-driven dissociation to a poor metal at similar to50 GPa. These results provide insight into which of the two published D(2) Hugoniots is probably correct. C1 Lawrence Livermore Natl Lab, Livermore, CA 94550 USA.

With a FWHM (full width at half maximum) of 0".2, Kalliope (apparent size of about 0".15) was not resolved but it was possible to separate the secondary from its primary whose apparent separation was of the order of 0".7 with a magnitude difference of 3.22 +/- 0.20. As each set of observations spanned a few days of time, they are well distributed along the secondary's orbit, enabling us to accurately estimate its orbit. The satellite orbits 22 Kalliope in a prograde manner with respect to Kalliope's rotational spin (which is in a retrograde sense relative to its orbit around the Sun), on a highly inclined (i = 19.8 +/- 2.0 with respect to the equator of 22 Kalliope) and moderately eccentric orbit (e = 0.07 +/- 0.02) with an orbital period of 3.58 +/- 0.08 days. The semi-major axis is 1020 +/- 40 km. Using Kalliope's diameter as determined from IRAS data, the asteroid's bulk density is about 2.03 +/- 0.16 g cm(-3), suggestive of a highly porous body with a porosity of 70% considering that the grain density of its meteoritic analog is of similar to 7.4 g cm(-3). This suggests a rubble pile, rather than solid, body. The measured nodal precession rate of the secondary's orbit seems to be much higher than expected from Kalliope's oblateness, assuming a homogeneous body (constant density). This suggests that Kalliope may be 60% more elongated or 35% larger than presently believed or/and that its internal structure is highly inhomogeneous with a denser outer shell.

Keck I telescope, we observed near-infrared emission at 2.2 mum from volcanic hotspots on Io in July-August 1998. Using several hundreds of short-exposure images we reconstructed diffraction-limited images of to on each of three nights. We measured the positions of individual hotspots to +/-0.004" or better, corresponding to a relative positional error of similar to 20 kin on Io's surface. The sensitivity of normal ground-based images of Io is limited by confusion between overlapping sources; by resolving these multiple points we detected up to 17 distinct hotspots, the largest number ever seen in a single image. During the month-long span of our 1998 observations, several events occurred. Loki was at the end of a long brightening, and we observed it to fade in flux by a factor of 2.8 over the course of one month. At the 3-sigma level we see evidence that Loki's position shifts by similar to 100 km. This suggests that the brightening may not have been located at the "primary" Loki emission center but at a different source within the Loki caldera. We also see a bright transient source near Loki. Among many other sources we detect a dim source on the limb of Io at the latitude of Pele; this source is consistent with 2.7% of the thermal emission from the Pele volcano complex being scattered by the Pele plume, which would be the first detection of a plume through scattered infrared hotspot emission.

Motivated by recent passivity-based controllers for underactuated systems, we design several controllers that asymptotically regulate, the planar gantry position and the payload angle. Specifically, utilizing LaSalle's invariant set theorem, we first illustrate how a simple proportional-derivative (PD) controller can be utilized to asymptotically regulate the overhead,crane system. Motivated by the desire to achieve improved transient performance, we then present two nonlinear controllers that increase the coupling between the planar gantry position and the,payload angle. Experimental results are provided to illustrate the improved performance of the nonlinear controllers over the simple PD controller.

They find an improvement in the intrinsic properties with increasing strain but the dominant effect in device performance is an extrinsic effect-the overall radiative efficiency, which is found to be less than 30% for all three samples even at 200 K. The authors attribute this to nonradiative recombination within the quantum well. The intrinsic gain-spontaneous current density characteristics of all three samples exhibit similar tangential gain parameters and a decreasing transparency current density from 116 to 87 to 83 Acm(-2) with increasing strain and well width. They show that the reduction occurs because of a reduction in the TE polarized spontaneous recombination due to the increased splitting of light and heavy hole subbands. The quasi-Fermi level separation required to achieve a fixed value of gain is insensitive to the particular strain/well width combination. The authors use a microscopic laser theory to model the behavior of a larger range of combinations of tensile strain and well width than were examined experimentally, having first demonstrated that the model correctly describes the experimental gain spectra of the only sample exhibiting appreciable gain in both TM and TE polarizations. The calculated data suggest that using still larger values of strain and well width produces no further benefit in performance.

Thermogravimetric analysis (TGA) and X-ray diffraction (XRD) studies show that the samples consist of Pr2Fe14B and alpha-Fe phases,at low B content, and Pr2Fe14B, alpha-Fe and Fe3B at high B content. The metastable Pr2Fe23B3 phase,appears in the intermediate B content (8-12 at%). This metastable Pr2Fe23B3 phase results in a poor squareness in the demagnetization curve and. is detrimental to the hard magnetic properties. Transmission electron microscopy (TEM) studies reveal larger average grain sizes when the B content is at 8.5 at% or above. It is further found that this metastable phase can be transformed into Pr2Fe14B, alpha-Fe, and Fe3B by annealing the sample at temperature of 750 degreesC or above, leading to a more square demagnetization curve. However, B-r of the nanocomposite decreases slightly due to the excessive grain growth during high-temperature annealing. C1 Magnequench Technol Ctr, Durham, NC 27709 USA.

A strain gauge was attached on the a-b plane oriented to measure the strain along the b axis and a magnetic field of H = 0.8 x 10(6) A/m (B = 1 Tesla) was applied along this same b axis. The sample was then rotated through 45degrees, 90degrees, 120degrees, 165degrees, and 180degrees from the direction of the applied magnetic field and the thermal expansion measurements were repeated. It Was found that there was an unexpected variation in the temperature at which the sudden discontinuity in strain occurred. The results seem to suggest that the transition temperature changes with direction of applied field relative to the crystal lattice. This surprising result is attributed to the combined effects of the first order phase transformation and the presence of an anisotropy "field," which differs with angle. This combination of factors, therefore, results in a different strength of effective field being experienced by the magnetic moments on the Gd atoms depending on their orientation. Comparing this with the previously observed field dependence of the Curie temperature in this material provides a possible explanation for this highly unusual observation.

However, near room temperature, the material exhibits some magnetomechanical hysteresis, which becomes negligible for temperatures of 60 degreesC and above. Measurements indicate that doping the cobalt ferrite with silicon lowers the Curie temperature of the material. It was also found that the Curie. temperature of the material depends on the fabrication and processing procedure. These results offer the possibility of decreasing the room temperature magnetomechanical hysteresis through control of the Curie temperature, thereby altering the temperature dependence of magnetic and magnetomechanical properties.

The effects of pure shear stress on a planar magnetic material and those due to torque applied to a rod are analogous in the sense that they can be described in terms of a pair of tensile and compressive stresses acting at 45degrees to the neutral axis of the plate or the rod axis. In this work the responses of nickel to shear stresses were studied under various dc applied fields. A model description was developed as a generalization of the theory of magnetomechanical effect to include shear stresses. This theory can be used as an aid to interpretation of the experimental results. C1 Iowa State Univ, Ctr Nondestruct Evaluat, Ames, IA 50011 USA. Iowa State Univ, Dept Engn Mech, Ames, IA 50011 USA.

The periodicity and the size of individual elements of an array of Co dots were determined by measuring the intensities of a large number of diffraction orders and comparing them to model calculations performed within the framework of Fraunhoffer diffraction theory. Element-specific hysteresis loops along both the easy and hard axis of the array were measured by tuning the incident energy to the Co L-3. absorption edge.

In situ tunneling magnetoresistance measurements for a spin-dependent tunnel junction were directly compared to magnetic domain behavior imaged using magnetic force microscopy (MFM) under the same applied fields, allowing for detailed investigation of electronic behavior relative to magnetic behavior. From the results, it was found that the resistance in the hysteretic field range (less than the coercivity of Hc = 800 A/m or 10 Oe) corresponded with the complex magnetic domain behavior observed in the MFM images and qualitatively matched micromagnetically modeled junctions.

Existing methods use both local features and global layout information. In this paper, we propose a novel algorithm based on the global matching of Component Block Projections (CBP), which are the concatenated directional projection vectors of the component blocks of a document image. Compared to those existing methods, CBP-based template-matching methods possess two major advantages: 1) The spatial relationship among the component blocks of a document image is better represented, hence a very high matching accuracy can be obtained even for a large template set and seriously distorted input images; and 2) the effective matching distance of each template and the triangle inequality are proposed to significantly reduce the computational cost. Our experimental results confirm these advantages and show that the CBP-based template-matching methods are very suitable for DIR applications.

Framework and analysis tools SO INDOOR AIR LA English DT Article DE uncertainty; decision analysis; simulation; modeling; COMIS; quantile coefficient of variation ID AIR-FLOW; COMIS; INFORMATION; MODEL AB We describe a framework for developing response recommendations to unexpected toxic pollutant releases in commercial buildings. It may be applied in conditions where limited building- and event-specific information is available. The framework is based on a screening-level methodology to develop insights, or rules-of-thumb, into the behavior of air flow and pollutant transport. A three-stage framework is presented: (1) develop a building taxonomy to identify generic, or prototypical, building configurations; (2) characterize uncertainty and conduct simulation modeling to predict typical air flow and pollutant transport behavior; and (3) rank uncertainty contributions to determine how information obtained at a site might reduce uncertainties in the model predictions. The approach is applied to study a hypothetical pollutant release on the first floor of a five-story office building. Key features that affect pollutant transport are identified and described by value ranges in the building stock. Simulation modeling provides predictions and uncertainty estimates of time-dependent pollutant concentrations, following a release, for a range of indoor and outdoor conditions. In this exercise, we predict concentrations on the fifth floor to be an order of magnitude less than on the first, coefficients of variation greater than 2, and information about the HVAC operation and window position most reducing uncertainty in predicted peak concentrations.

PRISM takes the solution of the chemical kinetic ordinary differential equation system and parameterizes it with quadratic polynomials. To increase the accuracy, the parameterization is done piecewise, by dividing the multidimensional chemical composition space into hypercubes and constructing polynomials for each hypercube on demand, The polynomial coefficients are stored for subsequent repeated reuse. Initial cost of polynomial construction is expensive, but it recouped as the hypercube is reused, hence computational gain depends on the degree of hypercube reuse. We present two methods that help us to identify hypercubes that will ultimately have high reuse, this being accomplished before the expense of constructing polynomials has been incurred. one method utilizes the rate of movement of the chemical trajectory to estimate the number of steps the trajectory would make through the hypercube. The other method defers polynomial construction until a preset threshold of reuse has been met, an empirical method which, nevertheless, produces a substantial gain, The methods are tested on a 0-D chemical mixture and reactive flow 1-D and 2-D simulations of selected laminar and turbulent H2 + air flames. The computational performance of PRISM is improved by a factor of about 2 for both methods. (C) 2003 Wiley Periodicals, Inc.

High secondary ion yields following the impact of individual highly charged ions allow the application of coincidence counting techniques. Statistical analysis of secondary ion emission events gives insight on the surface chemistry of single molecules. While not a direct imaging technique, coincidence analysis allows the characterization of surfaces on a length scale of a few nanometers, well beyond limits imposed by probe beam sizes. We apply this capability to the analysis of gramicidin S and its interaction with sodium impurities and 2,5-dihydroxybenzoic acid matrix molecules. (C) 2003 Elsevier B.V. All rights reserved.

Rapid quenching results in large thermal stress gradients that lead to high levels of residual stress. For products such as plates and extrusions, stretching by a few percent can reduce these stresses, but the stresses are not completely relieved. This report presents a simplified analytical model of the stress relief process illustrating the effects of through-thickness property gradients on residual stress after stretching. The basic conclusion is that for plates with uniform yield surface shapes through the thickness, the through-thickness residual stress range after stress relief is equal to the strength range in the direction of stretch. In extrusions, the bow after stress relief is proportional to this strength range. Cases are also considered in which the yield surface shapes range from isotropic to anisotropic through the thickness. Plastic anisotropy can perturb the effect of strength range on residual stress.

All the memory information is mapped onto a unitary operator acting upon a quantum state which represents a piece of information to be retrieved. As a result of only one quantum measurement, the address of the required information encoded in a number of the corresponding row of the unitary matrix is determined. By combining direct and dot products, the dimensionality of the memory space can be made exponentially large, using only linear resources. However, since the preprocessing, i.e., mapping the memory information into a Hilbert space can appear to be exponentially expensive, the proposed algorithm will be effective for NASA applications when the preprocessing is implemented on the ground, while the memory search is performed on remote objects.

The flow connects one point (source, sink) to a number of points (sinks, sources) distributed uniformly over a two-dimensional domain. In the first part of the paper, the flow between neighboring points is modeled as fully developed through round tubes. It is shown that flow 'maldistribution' and the abandonment of symmetry are necessary for the development of flow structures with minimal resistance. The search for better flow structures can be accelerated: tubes that show a tendency of shrinking during the search can be assumed absent in future steps of structure optimization. In the second part of the paper, the flow medium is continuous and permeated by Darcy flow. The development of flow structures (channels) is modeled as a mechanism of erosion, where elements of the original medium are removed one by one, and are replaced with a more permeable medium. The elements selected for removal are identified based on two criteria: maximum pressure integrated over the element boundary, and maximum pressure gradient. The flow structures generated based on the pressure gradient criterion have consistently smaller flow resistances. As flow systems become smaller and more compact, the flow systems themselves become "designed porous media". These design optimization trends revealed are generally applicable in constructal design, i.e., where miniaturization, global performance, compactness and complexity rule the design.

The magnitude of the effective longitudinal piezoelectric coefficient (d(33)) of these films is measured by a double-beam laser interferometric method. With increasing Ti-content, larger remanent polarization and higher coercive voltage are observed. The squareness of the polarization hysteresis loop is optimized in a Ti-rich compositiom The remanent d(33) values are maximized near a morphotropic phase boundary (MPB) composition, and the trend of d(33) values strongly depends on the dielectric constant. It is observed that maximum dielectric constant is achieved near MPB composition, showing the same trend as bulk PZT ceramics. This result indicates that the piezoelectric response in 1-mum-thick films with composition (Zr to Ti ratio) is governed by extrinsic contribution such as that found in bulk PZT ceramics rather than intrinsic contribution.

One of the most important of these components is the pit, that portion of the weapon that contains the fissile element plutonium. The U.S. government has proposed construction of a new Modern Pit Facility, and a key variable in planning both the size and schedule for this facility is the minimum estimated lifetime for stockpile pits. This article describes the current understanding of aging effects in plutonium, provides a lifetime estimate range, and outlines in some detail methodology that will improve this estimate over the next few years.

A split-Hopkinson pressure bar (SHPB) was used to achieve strain rates of about 2500 s(-1) and conventional testing machines were used for strain rates from 0.001 s(-1) to 1 s(-1). A large variation in the mechanical response was observed over the range of temperatures tested for both polymers showing "yield" and "plastic" deformation below the glass transition temperature (T-g). Above T-g both thermoplastic polymers exhibited increasing loading moduli with increasing strain rate or decreasing temperature. Tg appears to shift to higher temperatures as the strain rate increases. Below T-g both thermoplastic polymers exhibited a yield-type behavior followed by anelastic deformation. PEEK was seen to be more sensitive to strain rate and temperature than PA1. A range of different flow stress versus strain behaviors was observed at different temperatures and strain rates.

The micro structurally based constitutive equations describing the mechanical behavior of the mixed alpha and gamma phases are proposed. It is shown that for a given finishing temperature and strain, the Nb steel exhibits strong influence of strain rate on the flow stress and final structure. This tendency is also observed in calculated results obtained using proposed modeling procedures. High strain rates influence the deformation mechanism and reduce the extent of recovery occurring during and after deformation and, in turn, increase the driving force for transformation. On the other hand, the ratio of nucleation rate to growth rate increases for lower strain rates (due to the higher number of nuclei that can be produced during an extended loading time) leading to the refined ferrite structure. However, as it was expected such behavior produces higher inhomogeneity in the final product. Multistage quasistatic compression tests and test using the Hopkinson Pressure Bar under different temperature, strain, and strain rate conditions, are used for verification of the proposed models.

The model is developed within the context of a properly invariant nonlinear thermomechanical theory. A second order damage tensor is introduced which allows simulation of weakening to tension applied in one direction, without weakening to subsequent tension applied in perpendicular directions. This damage tensor can be advected using standard methods in computer codes. Porosity is used as an isotropic measure of volumetric void strain and its evolution is influenced by tensile failure. The rate of dissipation due to directional tensile failure takes a particularly simple form, which can be analyzed easily. Specifically, the model can be combined with general constitutive equations for porous compaction and dilation, as well as viscoplasticity. A robust non-iterative numerical scheme for integrating these evolution equations is proposed. This constitutive model has been implemented into an Eulerian shock wave code with adaptive mesh refinement. A number of simulations of complicated shock loading of different materials have been performed including problems of fracture of rock. These simulations show that directionality of damage can play a significant role in material failure. C1 Lawrence Livermore Natl Lab, Livermore, CA 94550 USA.

An additional series of uniaxial strain incipient failure experiments were performed using the annealed material. Damage quantification of the incipient failure specimens was performed and statistically reduced for comparison with continuum damage model predictions from explicit simulations of the experiments. Experimentally the test to test variability of the dynamic strain and flow stress measurements greatly exceeded that of the quasi-static measurements. Only the experiments with dynamic strain measurements close to post-test sample measurements were simulated. The ability of the simulations and the dynamic stress-strain measurements to detect the damage induced softening is low, at least until the damage coalesces into a crack. The damage model predictions of porosity evolution are within a factor of two for two experiments that differ in strain rate and stress triaxiality by over an order of magnitude.

Gas guns and time-resolved laser interferometry have been used to measure the fine structure in the particle velocity profiles resulting from symmetric plate impact. Impact velocities ranged from 0.40 km/s to 1.20 km/s. These experiments have allowed us to estimate the dynamic yield strength, and the spall strength of the "as-received" and heat-treated AerMet(R) 100 steel. The as-received material undergoes a phase transformation at around 13 GPa, while the heat-treated material exhibits the phase change at similar to 15GPa. The results of this study clearly suggest that the dynamic yield strength, spall strength and the phase transition kinetics are influenced by the heat-treatment.

The 316L SS sample loaded to 6.6 GPa using a square-topped pulse with a pulse duration of 0.9 musec displayed incipient spallation while the sample loaded to the identical peak shock pressure but with a triangular-shaped loading pulse (which immediately unloads the sample after the peak Hugoniot stress is achieved) exhibited no damage. To achieve an approximately equivalent level of incipient spall using a triangular-shaped loading pulse, an similar to 2X increase in the peak Hugoniot stress was required. Detailed metallographic and microtextural analysis of the damage evolution in spalled 316L SS samples as a function of loading pulse shape and the peak Hugoniot stress is presented.

In general. the shock process for powdered materials has utilized the traditional pressure-volume shock relationships proportioned to the initial packing densities of the powders. However. this approach and its resulting data are in controversy due to the lack of knowledge of its associated particle strain and strain temperature uncertainties. This paper will describe the current understanding, as well as the experimental technique used to obtain the shock response for distended materials. The above parameters are described within a pressure-strain-temperature interdependence. It was found that the experimentally measured strain heat was not only a function of initial packing density but also a function of powder size and distribution.

Some are used as the binder phase in plastic bonded explosives (PBXs) and propellants. Others are used either as components for structures or as the hinder phase in carious composite systems. Such materials need to be understood so that their response may be understood and constitutive descriptions constructed. This work presents experimental data focused tit the evaluation of the equation-of-state (EOS) and strength behaviour of four selected polymers. The equation of state and the shear strength of each polymer were measured as a function of impact stress and this gives insight into the role of the microstructure and its relation to response.

The brittle nature of ceramics suggest that impact loading of a ceramic attained due to subsonic impact could change the initial shear strength of the ceramic. If so, the subsequent behaviour of the ceramic may not be dependent on the the initial strength. Thus, it is necessary to determine the shear strength of a cermaic under single and multiple impacts. The present work determines the change in the shear strength of silicon carbide under a single shock, shock-reshock, and shock-release wave propagation, respectively. The material used in this work is marketed by CERCOM Inc. as SiC-B. The results of this work indicate that shear strength of SiC-B increases under shock-reshock.

The defects created are characterized by transmission electron microscopy. An orientation-dependent threshold stress for twinning is observed. The results are rationalized in terms of a criterion in which slip and twinning are considered as competing mechanisms. A constitutive description is applied to the two orientations, incorporating both slip and twinning. The predictions are in agreement with experiments. The threshold stress for twinning in the [001] orientation is 20-40 GPa, whereas the one for the [134] orientation is 40-60 GPa. The threshold stress is calculated, considering the effect of shock heating. The constitutive description provides a rationale for the experimental results; the calculated thresholds are 18 GPa for [001] and 25 GPa for [134]. A mechanism for void generation and growth based on the emission of geometrically necessary dislocations is proposed and analytically formulated. C1 Univ Calif San Diego, La Jolla, CA 92093 USA.

Special attention is given to the heat treating conditions in the two-phase (ferrite and austenite) region and resulting microstructure after the spall loading condition. One of the fundamental principles of any thermomechanical processing in the two-phase region is the simultaneous superposition of microstructure evolution and mechanical behavior of particular phase. The degree of generated defects, cracks and phases, and phase transformation is decisive for the final microstructure and the fracture resistance. Preliminary results show the banded structure still exists after the spall test and, totally unexpected lack of the visible characteristic voids, cracks or shear instabilities due to the tensile loading at the mid plane of the sample.

It has been found that the HEL, spall strength and shear strengths are all dependent upon the initial microstructure , with the material possessed of the duplex microstructure being the stronger. This is in agreement with quasi-static measurements. Shear strength has been observed to increase rapidly with increasing longitudinal stress, more so than in Ti-6Al-4V, indicating that the high degree of work hardening is an important factor in determining the shear strength of metallic and intermetallic materials.

Lake temperatures in the model were based on analyses derived from daily satellite measurements. The model performance was evaluated using operational surface and upper-air meteorological measurements and surface chemical measurements. Reasonable agreement between the simulations and observations was obtained. The bias (predicted - observed) over the simulation period was only -1.3 ppb for the peak ozone mixing ratio during the day and 5.5 ppb for the minimum ozone mixing ratio at night. High ozone production rates were produced over the surface of the lakes as a result of stable atmospheric conditions that trapped ozone precursors within a shallow layer during the day. In one location, an increase of 200 ppb of ozone over a 9-h period was produced by chemical production that was offset by losses of 110 ppb through vertical mixing, horizontal transport, and deposition. The predicted ozone was also sensitive to lake temperatures. A simulation with climatological lake temperatures produced ozone mixing ratios over the lakes and around the lake shores that differed from the simulation with observed lake temperatures by as much as 50 ppb, while the differences over land were usually 10 ppb or less. Through a series of sensitivity studies that varied ozone precursor emissions, it was shown that a reduction of 50% in NOx or volatile organic compounds would lower the 60-ppb ozone exposure by up to 50 h month(-1) in the remote forest regions over the northern Great Lakes. The implications of these results on future climate change and air quality in the region are discussed. C1 Pacific NW Natl Lab, Richland, WA 99352 USA.

Two distinct phenomena, downstream instabilities and source oscillations, occur in certain domains of gas pressure, radio frequency power, and electronegative gas chemistry. The downstream instabilities develop at some location well below the plasma source. They are consistent with ion two-stream instabilities, in inductively coupled plasmas (ICPs) with sufficiently long downstream regions. Source oscillations consist of large amplitude density variations within the ICP plasma. They are consistent with capacitive to inductive mode transitions, in ICPs with sufficiently large capacitive currents. (C) 2003 American Institute of Physics.

It has been suggested that these donors are responsible for the large increases in electron concentration seen in ZnO samples annealed at elevated temperatures in H-2 gas. In order to make a quantitative connection between the amount of dissolved hydrogen and any observed changes in electrical properties, we have annealed single crystal ZnO samples from several sources in H-2 and D-2 gas at 750degreesC and compared the observed changes in carrier concentration with nuclear reaction analysis and secondary ion mass spectrometry profiles of deuterium. We find that the amount of deuterium remaining in our gas-charged samples is similar to3.6-5.5x10(17) cm(-3), substantially larger than the increase seen in conduction band electron densities at 350 K. Our modeling indicates that these gas treatments produce a hydrogen-related donor state at 0.036+/-0.004 eV below the conduction band minimum and also cause significant increases in the measured conduction band electron mobility. These mobility increases and other features of our data strongly suggest that a substantial fraction of the dissolved hydrogen forms complexes with (passivates) acceptor impurities. Analysis of optical and electrical data also indicates that, while hydrogen is present in significant amounts in as-received samples, it is not the dominant "native" donor. Several infrared absorption peaks are observed before and after H-2/D-2 exposure, which we identify with local O-H/D stretch modes. The most prominent of these has an asymmetric absorption peak at 3546 cm(-1) arising from a c-axis oriented defect dipole, which is postulated to be hydrogen located in a bond-centered position between oxygen and zinc atoms. Comparisons are made between our experimental results and density functional theory calculations. (C) 2003 American Institute of Physics. C1 Sandia Natl Labs, Albuquerque, NM 87185 USA.

Here, we introduce a reactive multilayer foil which contains a reduction-oxidation thermite reaction between CuOx and Al. Typically in reactive multilayer foils, elemental layers react and form a single intermetallic product. In this thermite reaction, however, aluminum and copper oxide are, respectively, oxidized and reduced and form aluminum oxide and copper. The fully dense multilayer foils provide a well-defined geometry for studying the thermodynamics, kinetics, and intermediate phase formation in the CuOx/Al thermite reaction. Here, sputter deposition of CuOx/Al multilayer foils is demonstrated, and x-ray diffraction and transmission electron microscopy, including high resolution transmission electron microscopy and electron spectroscopic imaging, are used to characterize the as-deposited foil and the final products. The heat released in the reaction is quantified using differential thermal analysis, and the velocity of the self-propagating reaction is reported. (C) 2003 American Institute of Physics.

Heating samples at a slow, controlled rate in a differential thermal analyzer showed that the reduction of CuOx and the oxidation of Al proceeded via two separate exotherms. To analyze this reaction pathway, samples were heated to various temperatures within these exotherms, quenched, and characterized with x-ray diffraction, Auger depth profiling, and transmission electron microscopy. Experimental evidence indicates that in the first reaction, CuOx is reduced to a mixture of CuO and Cu2O and an interfacial layer of Al2O3 grows to coalescence; the final products of the second exotherm are Cu, Al2O3, and Cu2O. The first exotherm was believed to be controlled by the two-dimensional, interface-limited growth of the Al2O3 layer, while the second exotherm was believed to be controlled by both the diffusion-limited one-dimensional growth of the Al2O3 and the interface-controlled growth of the Cu due to the reduction of Cu2O.

The Raman transverse optical (TO) mode is deconvoluted into two Gaussian functions for a-Si:H and intermediate components and one Lorenzian function for the c-Si component. We found that (a) in general, the change in structure is a function of the ratio of hydrogen to silane gas flow, R, but also depends on the SiH4 flow rate and total gas pressure; (b) there is a narrow structural transition region in which the short-range order of the a-Si:H network improves, i.e., the variation in bond angle of the a-Si network decreases from similar to10degrees to similar to8degrees once the c-Si grains start to grow; and (c) when the films were deposited using a high SiH4 flow rate of 22 sccm, the narrow TO mode with low peak frequency could be related to the column-like structures.

Oxygen in the growth ambient during close-spaced sublimation generally reduces this recombination rate; grain size does not have a strong effect. (C) 2003 American Institute of Physics.

We find that the essential character of the response-multiple resonances corresponding to spatial harmonics of standing plasmons under the metal grating-is caused by the static spatial modulation of electron density in the channel. Higher order plasmon modes become more optically active as the depth of the electron density modulation in the DQW tends towards unity. The maximum absorbance, at plasma resonance, is shown to be 1/2. Furthermore, the strongest absorption also occurs when the standing plasmon resonance coincides with the fundamental dipole mode of the ungated portion of the channel.

However, a quarter of the phiA1122 genome, one that includes about half of the morphogenetic and maturation functions, is significantly more closely related to coliphage T3 than to T7. It is proposed that the yersiniophage phiA1122 recombined with a close relative of the Y. enterocolitica phage phiYeO3-12 to yield progeny phages, one of which became the classic T3 coliphage of Demerec and Fano (M.

The cellular distribution of platinum(IV) drugs after 24 h is similar to that of cisplatin, consistent with the majority of administered platinum(IV) drugs being reduced. Micro-X-ray absorption near-edge spectra of cells treated with cisplatin and platinum(IV) complexes confirmed the reduction of platinum(IV) to platinum(II). In cells treated, the most difficult to reduce complex, cis,trans,cis-[PtCl2(OH)(2)(NH3)(2)], platinum(IV) was detected in the cells along with platinum(II). The observations are in accordance with the relative ease of reduction of the platinum(IV) complexes used and support the requirement of reduction for activation of platinum(IV) complexes.

Stiffness was defined as the reduced elastic modulus (Er), which is a material property related to the elastic modulus. Er was measured at the local contact while indenting the live sample at a constant loading rate using a spherical tip. Er was derived from the resultant force-displacement curves. Insect cuticle exhibits viscoelastic behavior. Constant loading rate quasistatic measurements were used so that the effects of viscosity and contact force adhesion introduced systematic measurement effects. E, values were as follows: larvae, mean (SE), 0.39 (0.01) MPa; the puparium without evidence of adult structures 15.43 (1.78) MPa; and the adult, measured in the puparium at the completion of metamorphosis, 4.37 (0.31) MPa. Thus, as expected, the puparium and adult cuticle were very much stiffer than larval cuticle. Results also indicated stiffness variation that related to developmental events. This study has shown that this quasistatic nanoindentation-scanning probe microscopy approach is a suitable method for analyzing live biological samples. C1 Durance Corp, Excelsior, MN 55331 USA.

S. Department of Energy Atmospheric Radiation Measurement Program Southern Great Plains site illustrates that surface radiation has a higher sensitivity to cloud liquid water path variations when compared to cloud drop effective radius variations. The mean, median, and standard deviation of observed cloud liquid water path and cloud drop effective radius are 0.120, 0.101, 0.108 mm and 7.38, 7.13, 2.39 mum, respectively. Liquid water path variations can therefore cause 3 times the variation in optical depth as effective radius - a direct consequence of the comparative variability displayed by the statistics of the two parameters. Radiative transfer calculations demonstrate that, over and above the impact of higher liquid water path variability on optical depth, normalized cloud forcing is 2 times as sensitive to liquid water path variations as it is to effective radius variations. Consequently, radiative transfer calculations of surface flux using observed liquid water paths and a fixed effective radius of 7.5 mum have a 79% correlation with observed values. This higher sensitivity of solar flux to liquid water path is a result of the regimes of natural occurrence of cloud liquid water paths and cloud drop effective radii.

DODA/{Mo72Fe30} complexes containing basically single {Mo72Fe30} clusters are observed when the {Mo72Fe30} aqueous solution is freshly prepared and contains mainly unimer or oligmer {Mo72Fe30} anions. The {Mo72Fe30} clusters tend to form supramolecular vesicle structures slowly in solution. At high surfactant concentrations, the DODA cationic surfactants can break the vesicle structure and form single {Mo72Fe30}/DODA complexes. At low surfactant concentrations, complexes containing the whole vesicles coated by a layer of DODA is formed and transferred into the organic phase. For the surfactant concentrations in between, the vesicles are partially destroyed, leading to the formation of complexes with large size distribution. Studying the behaviors of the interaction between DODA and {Mo72Fe30} anionic structures will help to further explore the complicated mechanism of the POM vesicle formation, which was recently discovered but still not fully understood. Such unique complex structures may also have potential applications as nanoreactors or nanocontainers. C1 Brookhaven Natl Lab, Dept Phys, Upton, NY 11973 USA.

Similar to recent studies of attention in monkeys, we show early "spike-like" activity (<200 ms poststimulus), most likely reflecting an early transient excitatory response mixed with feedback influences, followed by "slow-wave" activity (>200 ms poststimulus) in MEG cortical response profiles evoked by a visual working memory task. We experimentally dissociated the early transient activity from the later sustained activity ( predominately feedback) by conducting an auditory size classification task. Words, representing common objects, evoked activity in occipital cortex ( presumably due to imagery) even though visual stimuli were not present in this task. The initial "spike" was absent from the response profile obtained from occipital cortex, leaving only "slow-wave" activity, thereby allowing us to characterize or profile feedback activity in this situation. Attention or task relevance enhanced the initial "spike" and "slow-wave" activity in visually responsive areas. Prefrontal activity, along the superior frontal sulcus, evoked by the working memory task, was active later in time than initial activity in visual cortex and later than the earliest effect of attention modulation in visual cortex.

The new physics-based preconditioner presented in this manuscript is a minor modification to the operator-split preconditioner presented previously. Results show that the new preconditioner is more effective on test problems that are more nonlinear. (C) 2003 Elsevier B.V. All rights reserved. C1 Los Alamos Natl Lab, Los Alamos, NM 87545 USA.

The DFT models of interest are non-local theories which accurately treat hard-sphere fluid mixtures; attractive inter-particle potentials (Lennard-Jones) are added as perturbations. In this paper, we develop and demonstrate a new efficient method for an accurate non-local DFT. The method described here differs from previous work in the use of fast fourier transform (FFT) methods to carry out the convolutions. As with our previous real space work (J. Comput. Phys. 159(2) (2000) 407, 425), we demonstrate that the Fourier space approach can be solved with a Newton-GMRES approach; however, we now employ a very efficient matrix-free algorithm. A simple but effective preconditioner is presented. The method is demonstrated with calculations performed for one-, two-, and three-dimensional systems, including problems with single and multicomponent fluids. Timing comparisons with previous implementations are given. (C) 2003 Elsevier B.V. All rights reserved. C1 Sandia Natl Labs, Albuquerque, NM 87185 USA.

In this paper the flip chip assembly is represented as a bi-material strip consisting of the chip and underfill. Our analysis is focused on delamination along the chip-underfill interface due to thermal loading. The underfill is modeled as a composite material made of a polymer matrix and silica particles. Interfacial stresses are studied for several particle configurations: cases of one, two, or three particles near the interface and 30 different random particle arrangements. Interfacial fracture is investigated by evaluating the J integral and stress intensity factors. Statistics of random particle arrangements in the underfill are also discussed. The interfacial stress and fracture analyses give the same trends. C1 Lockheed Martin Aeronaut Co, Marietta, GA 30063 USA. Georgia Inst Technol, GWW Sch Mech Engn, Atlanta, GA 30332 USA.

For many years, most oil field wastes were disposed of at a significant cost. However over the past decade, the industry has developed many processes and technologies to minimize the generation of wastes and to more safely and economically dispose of the waste that is generated. Many companies follow a three-tiered waste management approach. First, companies try to minimize waste generation when possible. Next, they try to find ways to reuse or recycle the wastes that are generated. Finally, the wastes that cannot be reused or recycled must be disposed of. Argonne National Laboratory (Argonne) has evaluated the feasibility of various oil field waste management technologies for the U.S. Department of Energy. This paper describes four of the technologies Argonne has reviewed. In the area of waste minimization, the industry has developed synthetic-based drilling muds (SBMs) that have the desired drilling properties of oil-based muds without the accompanying adverse environmental impacts. Use of SBMs avoids significant air pollution from work boats hauling offshore cuttings to shore for disposal and provides more efficient drilling than can be achieved with water-based muds. Downhole oil/water separators have been developed to separate produced water from oil at the bottom of wells. The produced water is directly injected to an underground formation without ever being lifted to the surface, thereby avoiding potential for groundwater or soil contamination: In the area of reuse/recycle, Argonne has worked with Southeastern Louisiana University and industry to develop a process to use treated drill cuttings to restore wetlands in coastal Louisiana. Finally, in an example of treatment and disposal, Argonne has conducted a series of four baseline studies to characterize the use of salt caverns for safe and economic disposal of oil field wastes.

Next, we point out that insight into the scarcity value of an ecosystem service can be gained generally by examining the manner in which the state of an ecosystem responds to changes in environmental conditions. Following this, we specialize our discussion to the case of eutrophication in lakes. This leads us to pose and analyze a stochastic control problem of lake management in which ecological thresholds are salient. Finally, we show that this stochastic control theoretic framework can be used to obtain a numerical value that is closely related to the scarcity value of an ecosystem service provided by lakes.
