Fluctuations in water level caused by these effects carry over in the water balance equation.

Consequently, natural inflow's signal may become noisy and affected by external errors. The main objective of this report is to evaluate the uncertainty caused by the effects of wind and hydraulic maneuvers on water balance equation. To this end, hydrodynamic models of reservoirs Outardes 4 and Gouin were prepared. According to the literature review, wind effects can be studied either by an unsteady state approach or by assuming steady state approach.

Unsteady state simulation of wind effects on reservoir Gouin and Outardes 4 were performed by hydrodynamic modelling. Consideration of an unsteady state implies that the wind conditions vary throughout the simulation. This feature allows taking into account temporal effect of wind duration. In addition, it also allows the consideration of inertial forces such as seiches which are caused by.

The du Bois sign. According to the current literature, the term " du Bois sign" characterizes the condition of a shortened fifth finger as a symptom of congenital syphilis, Down syndrome, dyscrania, and encephalic malformation. Modern medical dictionaries and text books attribute the eponym to the French gynecologist Paul Dubois Yet, a literature analysis revealed incorrect references to the person and unclear definitions of the term.

Our findings showed that the origin of the term is based on observations made by the Swiss dermatologist Charles du Bois in connection with congenital syphilis. In addition, a further eponymical fifth finger sign is closely associated with the du Bois sign. In conclusion, the du Bois sign has only limited diagnostic value and is frequently occurring in the normal healthy population.

Comparaison avec le calcul en 2D. In this paper, the finite element method is applied for the computation of the magnetostatic field in the windings of a shell-form reactor. The results are compared to those obtained in 2D. These calculation results are also compared to some test results. Elastic properties of multilayers with low period thickness show in some cases anomalies which are generally correlated with structural modifications in individual layers. In the recent past, several studies have evidenced using X-ray diffraction in-plane and out-of-plane strains with the same sign.

This result is surprising because the value of this coefficient in metals is generally positive. Therefore, the elastic anomaly concerning Poisson's ratio which has been reported by some authors in scientific literature do not result from real structure of multilayers but from experimental X-ray diffraction data analysis. Consequences experimentales des effets des fluctuations du vide sur la fluorescence parametrique et la generation du second harmonique en milieu confine. Les fluctuations du vide, qui consistent en l'apparition momentanee de particules, ce qui est permit par le principe d'incertitude de Heisenberg, joue un role primordial dans les processus photoniques, en particulier les processus non-lineaires.

Par la manipulation de ces fluctuations du vide a l'aide de confinement optique, on retrouve deux phenomenes particuliers: Dans ce travail, on presente les resultats dans le cas classique ; c'est-a-dire sans fluctuations du vide et confinement. Par la suite, on presente les effets des fluctuations du vide et du confinement, ce qui mene aux deux effets mentionnes. Dans le cas de la fluorescence parametrique, le bruit quantique sur le champ interne et externe est calcule , le role du desaccord de phase dans le modele est expose et une generalisation tridimensionnelle est etudiee afin de generaliser la conception du modele d'un cas unidimensionnel a un cas tridimensionnel planaire.

Dans le cas de la generation du second harmonique, les difficultes d'un modele purement tridimensionnel sont exposees et ensuite le cas limite planaire est etudie. Methode de calcul a N-corps basee sur la G0W0: Etude du couplage electron-phonon dans le C60 et developpement d'une approche acceleree pour materiaux organiques.

This thesis studies the limitations of density functional theory. These limits are explored in the context of a traditional implementation using a plane waves basis set. First, we investigate the limit of the size of the systems that can be treated. Cutting edge methods that assess these limitations are then used to simulate nanoscale systems. More specifically, the grafting of bromophenyl molecules on the sidewall of carbon nanotubes is studied with these methods, as a better understanding of this procedure could have substantial impact on the electronic industry.

Second, the limitations of the precision of density functional theory are explored. We begin with a quantitative study of the uncertainty of this method for the case of electron-phonon coupling calculations and find it to be substantially higher than what is widely presumed in the literature. The uncertainty on electronphonon coupling calculations is then explored within the G0W0 method, which is found to be a substantially more precise alternative. However, this method has the drawback of being severely limitated in the size of systems that can be computed.

In the following, theoretical solutions to overcome these limitations are developed and presented. The increased performance and precision of the resulting implementation opens new possibilities for the study and design of materials, such as superconductors, polymers for organic photovoltaics and semiconductors.

Effet de la substitution du cuivre par du lithium sur les proprietes de l'oxyde spinelle lithium x cuivre y-x cobalt 3-y oxygen 4 etudie pour l'electrocatalyse de la reaction de degagement de l'oxygene en milieu alcalin. L'electrolyse de l'eau demeure la seule technologie industrielle de generation de l'hydrogene et de l'oxygene tres purs sans rejet de CO2 dans l'atmosphere, ce qui le rend tres attrayant par rapport a la combustion de carburants fossiles qui provoque presentement de serieux problemes environnementaux.

Dans le but d'ameliorer le rendement de ce procede, nous avons developpe de nouveaux materiaux d'anode peu couteux, a base de l'oxyde mixte CuyCo3-yO 4, qui possedent une cinetique rapide pour la reaction de degagement de l'oxygene RDO. Cette reaction suscite un interet particulier en raison de la surtension d'activation relativement elevee a l'anode qui cause la principale perte de rendement du procede.

Le traumatisme du colon: We analyzed purification mechanisms of silicon by inductive plasma with a fluoride slag.

The aim is to study boron elimination from doped electronic grade silicon in function of the nature of the slag to obtain a photovoltaic grade silicon. The steady began with the calculation and the comparison of the stability diagram of boron compounds in presence of CaF2, BaF2 and MgF2. This study led us to conclude that BaF2 is the better slag for silicon purification.

This has been confirmed by experience. In a second time, we made purifications under electric bias to enhance slag efficiency.

Get Involved

We noticed that BaF2 is more sensitive to electric bias than other slags. A thickness measurement of the DU layer can be performed using an optical microscope where the total DU weight can be computed provided a uniform DU layer. Therefore, a non-destructive method for quantifying the DU content in hohlraums has been established by utilizing gamma-ray spectroscopy. The details of this method, along with results from several hohlraums, are presented in this report. Cri du Chat syndrome. The Cri du Chat syndrome CdCS is a genetic disease resulting from a deletion of variable size occurring on the short arm of chromosome 5 5p-.

The incidence ranges from 1: The main clinical features are a high-pitched monochromatic cry, microcephaly, broad nasal bridge, epicanthal folds, micrognathia, abnormal dermatoglyphics, and severe psychomotor and mental retardation. Malformations, although not very frequent, may be present: Molecular cytogenetic analysis has allowed a cytogenetic and phenotypic map of 5p to be defined, even if results from the studies reported up to now are not completely in agreement.

Genotype-phenotype correlation studies showed a clinical and cytogenetic variability. The identification of phenotypic subsets associated with a specific size and type of deletion is of diagnostic and prognostic relevance. Specific growth and psychomotor development charts have been established. Deletion of the telomerase reverse transcriptase hTERT gene, localised to 5p The critical regions were recently refined by using array comparative genomic hybridisation. The cat-like cry critical region was further narrowed using quantitative polymerase chain reaction PCR and three candidate genes were characterised in this region.

The diagnosis is based on typical clinical manifestations. Karyotype analysis and, in doubtful cases, FISH analysis will confirm the diagnosis. There is no specific therapy for CdCS but early rehabilitative and educational interventions improve the prognosis and considerable progress has been made in. L'Aventure du LHC.

La construction du LHC fut longue et difficile. Contribution to the G 0 violation of parity experience: In the framework of quantum chromodynamics, the nucleon is made of three valence quarks surrpounded by a sea of gluons and quark-antiquark pairs. Only the only lightest quarks u, d and s contribute significantly to the nucleon properties.

In Go we using the property of weak interaction to violate parity symmetry, in order to determine separately the contributions of the three types of quarks to nucleon form factors. The experiment, which takes place at Thomas Jefferson laboratory USA , aims at measuring parity violation asymmetry in electron-proton scattering.

To extract an asymmetry with small errors, it is necessary to correct all the beam parameters, and to have high enough counting rates in detectors. A special electronics was developed to treat information coming from 16 scintillator pairs for each of the 8 sectors of the Go spectrometer. A complete calculation of radiative corrections has been clone and Monte Carlo simulations with the GEANT program has permitted to determine the shape of the experimental spectra including inelastic background.

This work will allow to do a comparison between experimental data and theoretical calculations based on the Standard Model. Poumon du puisatier.

Application aux aciers. In the present paper, the so-called " ultrasonic fatigue " or fatigue at very high frequency has been studied in the materials elastic behaviour case while neglecting the thermal effects that influence the mechanical fields. The determination of mechanical fields and specimen resonance length has been done both analytically and numerically. The numerical method used for this calculation is the finite element method FEM. Martensitic steel " Soleil A2 " and austenitic steel " ICL BC " have been considered in order to compare the two methods analytical and numerical.

Les scores moyens des sous-dimensions du MBI: A short partial sequence of 28 amino acids is all the information we have so far about the putative allergen 2S albumin from almond. The aim of this work was to analyze this information using mainly bioinformatics tools, in order to verify its rightness. Based on the results reported in the paper describing this allergen from almond, we analyzed the original data of amino acids sequencing through available software.

The degree of homology of the almond 12kDa protein with any other known 2S albumin appears to be much lower than the one reported in the paper that firstly described it. In a publicly available cDNA library we discovered an expressed sequence tag which translation generates a protein that perfectly matches both of the sequencing outputs described in the same paper. A further analysis indicated that the latter protein seems to belong to the vicilin superfamily rather than to the prolamin one. The fact that also vicilins are seed storage proteins known to be highly allergenic would explain the IgE reactivity originally observed.

Based on our observations we suggest that the IgE reactive 12kDa protein from almond currently known as Pru du 2S albumin is in reality the cleaved N-terminal region of a 7S vicilin like protein. All rights reserved. Cirque du Monde as a health intervention. Study selection The first 50 articles or websites identified for each key word in each of the databases were examined on the basis of their titles and abstracts in the case of articles, and on the basis of their titles and page content in the case of websites. Articles and websites that explored an aspect of social circuses or that described an intervention that involved circuses were then retained for analysis.

Because all literature on social circuses was searched, no criterion for year of publication was used. Synthesis No articles on the social circus as a health intervention were found. One study on the use of the circus as an intervention in schools was identified. It demonstrated an increase in self-esteem in the children who took part. One study on the use of the circus in a First Nations community was found; it contained nonspecific, qualitative findings. The other articles identified were merely descriptions of social circuses. One website was identified on the use of the social circus to help youth who had been treated in a hospital setting for major psychiatric disorders to re-enter the community.

Implications for U. Amelioration de l'efficacite energetique du procede d'electrolyse de l'aluminium conception d'un nouveau bloc cathodique. Dans ce contexte, des petits gains en efficacite energetique des cuves d'electrolyse pourraient avoir un impact important sur la reduction globale de la consommation d'electricite. Le projet de maitrise decrit dans cette etude repond a la problematique suivante: Le but premier du projet est de modifier la geometrie en vue d'ameliorer le comportement thermoelectrique des blocs cathodiques et d'accroitre par le fait meme l'efficacite energetique du procede de production d'aluminium.

La mauvaise distribution de la densite de courant dans la cuve est responsable de certains problemes energetiques ayant des impacts negatifs sur l'economie et l'environnement. Cette non-uniformite de la distribution du courant induit une usure prematuree de la surface de la cathode et contribue a reduire la stabilite magnetohydrodynamique de la nappe de metal liquide. Afin de quantifier les impacts que peut avoir l'uniformisation de la densite de courant a travers le bloc cathodique, un modele d'un bloc cathodique d'une cuve de la technologie AP a ete concu et analyse par elements finis.

A partir de son comportement thermoelectrique et de donnees experimentales d'une cuve AP tirees de la litterature, une correlation entre le profil de densite de courant a la surface du bloc et le taux d'erosion local au meme endroit a ete creee. Cette relation correspond au modele predictif de la duree de vie de tout bloc du meme materiau a partir de son profil de densite de courant.

Ensuite, une programmation a ete faite incorporant dans une meme fonction cout les impacts economiques de la duree de vie, de la chute de voltage cathodique et de l'utilisation de nouveaux materiaux. Comparative study on Du Pont analysis and DEA models for measuring stock performance using financial ratio. Determining stock performance using financial ratio is challenging for many investors and researchers. Financial ratio can indicate the strengths and weaknesses of a company's stock performance.

There are five categories of financial ratios namely liquidity, efficiency, leverage, profitability and market ratios. It is important to interpret the ratio correctly for proper financial decision making. The study is conducted in involving consumer products companies listed in Bursa Malaysia. The estimation method of Data Envelopment Analysis computes the efficiency scores and ranks the companies accordingly.

The Du Pont analysis is a traditional tool for measuring the operating performance of companies. In this study, Du Pont analysis is used to evaluate three different aspects such as profitability, efficiency of assets utilization and financial leverage. This study finds that both analysis models provide different rankings of the selected samples. Hypothesis testing based on Pearson's correlation, indicates that there is no correlation between rankings produced by DEA and Du Pont analysis.

The method cannot provide complete ranking because the values of Balance Index is equal and zero. Thermoplastic composite parts manufacture at Du Pont. Low-cost routes to the manufacture of complex shaped composite parts have been defined using metal forming techniques and Du Pont's long discontinuous fiber LDF Technology.

These manufacturing techniques include roll forming, stretch forming, and press forming. Near equivalence between the static, dynamic, and damage tolerance properties of LDF and continuous fiber composites have been demonstrated. Several examples are cited which demonstrate the potential for this technology to significantly reduce the cost of aerospace components. Sustainable growth, the Du Pont way. Like many manufacturers, Du Pont traditionally has grown by making more and more "stuff.

Over the years, though, Du Pont became aware that cheap supplies of nonrenewable resources wouldn't be endlessly available and that the earth's ecosystems couldn't indefinitely absorb the waste and emissions of production and consumption. Chad Holliday, chairman and CEO of Du Pont, believes strongly in the challenge of sustainable growth and makes the business case for it: By using creativity and scientific knowledge effectively, he says, companies can provide strong returns for shareholders and grow their businesses--while also meeting the human needs of societies around the world and reducing the environmental footprint of their operations and products.

In fact, a focus on sustainability can help identify new products, markets, partnerships, and intellectual property and lead to substantial business growth. Holliday describes how Du Pont developed a three-pronged strategy to translate the concept of sustainability into nuts-and-bolts business practices. Focusing on integrated science, knowledge intensity, and productivity improvement, the strategy was accompanied by a new way to measure progress quantitatively.

Sustainable growth should be viewed not as a program for stepped-up environmental performance but as a comprehensive way of doing business, one that delivers tremendous economic value and opens up new opportunities. Ultimately, companies will find that they can generate substantial business value through sustainability while both enhancing the quality of life around the world and protecting the environment.

Mesure de haute resolution de la fonction de distribution radiale du silicium amorphe pur. Cette these porte sur l'etude de la structure du silicium amorphe prepare par irradiation ionique. Elle presente des mesures de diffraction de rayons X sur de la poudre de silicium cristallin, du silicium amorphe relaxe et non relaxe, ainsi que tous les developpements mathematiques et physiques necessaires pour extraire la fonction de distribution radiale correspondant a chaque echantillon.

Au Chapitre I, nous presentons une methode de fabrication de membranes minces de silicium amorphe pur.

Il y a deux etapes majeures lors du processus de fabrication: Nous avons caracterise premierement les membranes de silicium amorphe par spectroscopie Raman pour verifier qu'il ne reste plus de trace de materiau cristallin dans les films amorphes. Une deuxieme caracterisation par detection de recul elastique ERD-TOF sur ces memes membranes a montre qu'il y a moins de 0. Au Chapitre II, nous proposons une nouvelle methode de correction de la contribution inelastique "Compton" des spectres de diffusion totale afin d'extraire les pics de diffusion elastique, responsable de la diffraction de Bragg.

L'article presente tout d'abord une description simplifiee d'une theorie sur la diffusion inelastique dite "Impulse Approximation" IA qui permet de calculer des profils de Compton en fonction de l'energie et de l'angle de diffusion 2theta.

Ces profils sont utilises comme fonction de lissage de la diffusion Compton experimentale. Pour lisser les pics de diffusion elastique, nous avons utilise une fonction pic de nature asymetrique. Aux Chapitre III, nous exposons de maniere detaillee les resultats des experiences de diffraction de rayons X sur les membranes de silicium amorphe et la poudre de silicium cristallin que nous avons preparees.

Nous abordons aussi les. Influence of channel base current and varying return stroke speed on the calculated fields of three important return stroke models. The characteristics of the field wave shapes are shown to be very sensitive to the channel base current, especially the field zero crossing at km for the TCS and DU models, and the magnetic hump after the initial peak at close range for the TCS models. Also, the DU model is theoretically extended to include any arbitrarily varying return stroke speed with height.

A brief discussion is presented on the effects of an exponentially decreasing speed with height on the calculated fields for the TCS, MTL, and DU models. On-Site was developed to provide modelers and model reviewers with prepackaged tools " calculators " for performing site assessment calculations. The philosophy behind OnSite is that the convenience of the prepackaged calculators helps provide consistency for simple calculations , La resolution de l'equation de Boltzmann demeure une etape importante dans la prediction du comportement d'un reacteur nucleaire.

Malheureusement, la resolution de cette equation presente toujours un defi pour une geometrie complexe reacteur tout comme pour une geometrie simple cellule. Ainsi, pour predire le comportement d'un reacteur nucleaire,un schema de calcul a deux etapes est necessaire. La premiere etape consiste a obtenir les parametres nucleaires d'une cellule du reacteur apres une etape d'homogeneisation et condensation.

La deuxieme etape consiste en un calcul de diffusion pour tout le reacteur en utilisant les resultats de la premiere etape tout en simplifiant la geometrie du reacteur a un ensemble de cellules homogenes le tout entoure de reflecteur. Lors des transitoires accident , ces deux etapes sont insuffisantes pour pouvoir predire le comportement du reacteur. Comme la resolution de l'equation de Boltzmann dans sa forme dependante du temps presente toujours un defi de taille pour tous types de geometries,un autre schema de calcul est necessaire. Afin de contourner cette difficulte, l'hypothese adiabatique est utilisee.

Elle se concretise en un schema de calcul a quatre etapes. La premiere et deuxieme etapes demeurent les memes pour des conditions nominales du reacteur.

La troisieme etape se resume a obtenir les nouvelles proprietes nucleaires de la cellule a la suite de la perturbation pour les utiliser, au niveau de la quatrieme etape, dans un nouveau calcul de reacteur et obtenir l'effet de la perturbation sur le reacteur. Ce projet vise a verifier cette hypothese. Ainsi, un nouveau schema de calcul a ete defini.

La premiere etape de ce projet a ete de creer un nouveau logiciel capable de resoudre l'equation de Boltzmann dependante du temps par la methode stochastique Monte Carlo dans le but d'obtenir des sections efficaces qui evoluent dans le temps. Ce code a ete utilise pour simuler un accident LOCA dans un reacteur nucleaire de type.

Ce present projet de recherche a permis. Ce modele constitue une plate-forme numerique capable de discerner l'influence des proprietes mecaniques des fascias et de la cellule musculaire sur le comportement dynamique du muscle lors d'une contraction excentrique, notamment le module de Young et le module de cisaillement de la couche de tissu conjonctif, l'orientation des fibres de collagene de cette membrane et le coefficient de poisson du muscle.

La caracterisation experimentale in vitro de ces parametres pour des vitesses de deformation elevees a partir de muscles stries humains actifs est essentielle pour l'etude de lesions musculaires traumatiques. Le modele numerique developpe est capable de modeliser la contraction musculaire comme une transition de phase de la cellule musculaire par un changement de raideur et de volume a l'aide des lois de comportement de materiau predefinies dans le logiciel LS-DYNA v, Livermore Software Technology Corporation, Livermore, CA, USA. Le present projet de recherche introduit donc un phenomene physiologique qui pourrait expliquer des blessures musculaires courantes crampes, courbatures, claquages, etc.

La predominance de blessures musculaires lors de contractions excentriques est egalement exposee. Le modele developpe dans ce projet de recherche met ainsi a l'avant-scene le concept de transition de phase ouvrant la porte au developpement de nouvelles technologies pour l'activation musculaire chez les personnes atteintes de paraplegie ou de muscles artificiels compacts pour l'elaboration de protheses ou d'exosquelettes. Mots-cles Muscle strie, lesion musculaire, fascia, contraction excentrique, modele par elements finis, transition de phase.

These measurements showed that multiple time constants originating from multiplication, time-of-flight, scattering in the assembly and room return could be associated with this prompt neutron decay. In this work, the contribution not associated with neutron multiplication was investigated via measurements with a depleted uranium DU casting. The measurements at ORNL used an annular 5. This setup was identical to the configuration used in the previously performed measurements with HEU castings at Y The time correlation between fission events and detections in the plastic scintillators was measured, as well as the time distribution of coincidences between multiple detectors within a ns time window.

Time constants from decay fits to the HEU and DU data were compared to characterize the contributions resulting from multiplication, time-of-flight, and scattering.

Le travail de recherche effectue durant mon projet de maitrise en physique a l'Universite du Quebec a Trois-Rivieres dans les laboratoires de l'Institut de Recherche sur l'Hydrogene etait de comparer l'effet du laminage a froid de la poudre de MgH2 avec celui du broyage mecanique. Nous avons etudie cette nouvelle technique en utilisant un laminoir vertical concu specialement pour laminer de la poudre.

Nous avons lamine la poudre de MgH2 5, 25, 50 et fois. La comparaison de la morphologie de la poudre de MgH 2 telle que recu du manufacturier et broye mecaniquement pendant 30 minutes avec celle de la poudre laminee ete faite a l'aide d'un microscope electronique a balayage. Nous avons par la suite mesure les proprietes de sorption d'hydrogene grace un appareil PCT de type Sievert. Nous avons aussi determine la structure cristalline par diffraction de rayons X.

Nous avons aussi utilise les courbes de cinetiques d'absorption et de desorption d'hydrogene pour calculer l'etape limitative dans les reactions de sorption des echantillons lamines. Comme cinq laminages se font en environ 10 secondes, on voit que le laminage a froid est une technique plus interessante industriellement que le broyage mecanique a cause de l'important gain en temps et en energie.

Cri- du -Chat syndrome, also called the 5p-syndrome, is a rare genetic abnormality, and only few cases have been reported on its brain MRI findings. We describe the magnetic resonance imaging findings of a 1-year-old girl with Cri- du -Chat syndrome who showed brain stem hypoplasia, particularly in the pons, with normal cerebellum and diffuse hypoplasia of the cerebral hemispheres. We suggest that Cri- du -Chat syndrome chould be suspected in children with brain stem hypoplasia, particularly for those with high-pitched cries.

Nouvelles approches en theorie du champ moyen dynamique: Les applications reliees a la generation d'energie motivent la recherche de materiaux ayant un fort pouvoir thermoelectrique S. De plus, S nous renseigne sur certaines proprietes fondamentales des materiaux, comme, par exemple, la transition entre l'etat coherent et incoherent des quasi-particules lorsque la temperature augmente.

Empiriquement, la presence de fortes interactions electron-electron peut mener a un pouvoir thermoelectrique geant. Nous avons donc etudie le modele le plus simple qui tient compte de ces fortes interactions, le modele de Hubbard. La theorie du champ moyen dynamique DMFT est tout indiquee dans ce cas.

Nous nous sommes concentres sur un systeme tridimensionnel 3d cubique a face centree fcc , et ce, pour plusieurs raisons.

A Ce type de cristal est tres commun dans la nature. B La DMFT donne de tres bons resultats en 3d et donc ce choix sert aussi de preuve de principe de la methode. C Finalement, a cause de la frustration electronique intrinseque au fcc, celui-ci ne presente pas de symetrie particule-trou, ce qui est tres favorable a l'apparition d'une grande valeur de S.

Ce travail demontre que lorsque le materiau est un isolant a demi-remplissage a cause des fortes interactions isolant de Mott , il est possible d'obtenir de grands pouvoirs thermoelectriques en le dopant legerement. C'est un resultat pratique important. Du point de vue methodologique, nous avons montre comment la limite de frequence infinie de S et l'approche dite de Kelvin, qui considere la limite de frequence nulle avant la limite thermodynamique pour S, donnent des estimations fiables de la vraie limite continue DC dans les domaines de temperature appropriee. Ces deux approches facilitent grandement les calculs en court-circuit ant la necessite de recourir a de problematiques prolongements analytiques.

Nous avons trouve que la methode de calcul a frequence infinie fonctionne bien lorsque les echelles d'energie sont relativement faibles. En d'autres termes. Carte du Ciel, San Fernando zone.

When polymer and liquid are contacted with each other, as in packaging, some mass exchanges may occur, which constitute a major drawback when the liquid is a foodstuff or blood. However, these mass transfers in the polymers can appear as very interesting from the industrial point of view, if one is able to use and control them.

It is then necessary to have a good knowledge of these transfer processes which are controlled by diffusion. Dioctyl phthalate DOP migration into an edible oil was studied under worst conditions: The quantitative analysis of DOP in a such complex liquid medium and in the PVC itself was made easy by the use of the radioactive tracer technique. A simplified mathematical model, obtained by neglecting the oil transport in the PVC, was evaluated. Bashi, J.

In March , Merck signed a letter of intent with Trimeris to conduct a trial of efavirenz in combination with Trimeris's HIV fusion inhibitor, T, qv. All enrolled patients will be those who have begun to fail their existing triple combination therapy.

Prior exposure to NNRTIs and protease inhibitors, other than indinavir, will be among the exclusion criteria for the study. The first 10 days of the study were planned as a dose-optimization period to assess the safety, pharmacokinetics and antiviral activity of multiple ascending doses. Spectropolarimetry at Pic du Midi Observatory.

The 2m Telescope Bernard Lyot TBL is now fully dedicated to spectropolarimetric studies with the NARVAL instrument, which covers in a unique exposure the nm spectral range with a spectral resolution of 65,, and gives access to the 4 Stokes parameters. This lead to significant progress in our understanding of magnetism over the whole HR diagram, thanks to detections down to the Gauss level and the continuous follow-up of stars during many years. I will present illustrative recent results obtained with the NARVAL instrument, as well as the future instrumentation. Multiphase flow calculation software.

Multiphase flow calculation software and computer-readable media carrying computer executable instructions for calculating liquid and gas phase mass flow rates of high void fraction multiphase flows. The multiphase flow calculation software employs various given, or experimentally determined, parameters in conjunction with a plurality of pressure differentials of a multiphase flow, preferably supplied by a differential pressure flowmeter or the like, to determine liquid and gas phase mass flow rates of the high void fraction multiphase flows.

Embodiments of the multiphase flow calculation software are suitable for use in a variety of applications, including real-time management and control of an object system.

Hazardous Waste Cleanup: Du Pont manufactured a variety of products at the plant including, photographic films, automotive paints, pigments, adhesives, thinners,.

A Decomposition of Hospital Profitability: This paper evaluates the drivers of profitability for a large sample of U. Following a methodology frequently used by financial analysts, we use a Du Pont analysis as a framework to evaluate the quality of earnings. By decomposing returns on equity ROE into profit margin, total asset turnover, and capital structure, the Du Pont analysis reveals what drives overall profitability.

Profit margin, the efficiency with which services are rendered total asset turnover , and capital structure is calculated for 3, U. The sample is then stratified by ownership, size, system affiliation, teaching status, critical access designation, and urban or non-urban location. Sensitivity to regression methodology is also investigated using a seemingly unrelated regression. When the sample is stratified by hospital characteristics, the results indicate investor-owned hospitals have higher profit margins, higher efficiency, and are substantially more leveraged.

Hospitals in systems are found to have higher ROE, margins, and efficiency but are associated with less leverage. In addition, a number of important and significant interactions between teaching status, ownership, location, critical access designation, and inclusion in a system are documented. Many of the significant relationships, most notably not-for-profit ownership, lose significance or are predominately associated with one interaction effect when interaction terms are introduced as explanatory variables.

Results are not sensitive to the alternative methodology. The results of the Du Pont analysis suggest that although there appears to be convergence in the behavior of NFP and IO hospitals, significant financial differences remain. Large Scale GW Calculations. We present GW calculations of molecules, ordered and disordered solids and interfaces, which employ an efficient contour deformation technique for frequency integration and do not require the explicit evaluation of virtual electronic states nor the inversion of dielectric matrices.

We also present a parallel implementation of the algorithm which takes advantage of separable expressions of both the single particle Green's function and the screened Coulomb interaction. The method can be used starting from density functional theory calculations performed with semilocal or hybrid functionals.

Airborne antenna pattern calculations. Progress on the development of modeling software, testing software against caclulated data from program VPAP and measured patterns, and calculating roll plane patterns for general aviation aircraft is reported.

The determination of proper placement of antennas on aircraft to meet the requirements of the Microwave Landing System is discussed. An overview of the performed work, and an example of a roll plane model for the Piper PAT Cheyenne aircraft and the resulting calculated roll plane radiation pattern are included. Du Pont. Robert L. Du Pont, director of the National Institute on Drug Abuse NIDA , made headlines recently when he became one of the first Administration officials publicly to recommend a liberalization of marihuana laws.

The occasion was a press conference accompanying the release of Marihuana and Health, NIDA's fifth annual report to the Congress on marihuana research. Recently, Science talked with Du Pont and asked him to elaborate on those views. Du Pont, a year-old Harvard M. He held that position until the office was terminated on 30 June DU Processing Efficiency and Reclamation: Plasma Arc Melting. The work described here corresponds to one piece of a larger effort to increase material usage efficiency during DU processing operations.

In order to achieve this goal, multiple technologies and approaches are being tested. These technologies occupy a spectrum of technology readiness levels TRLs.

This paper describes system calculations made in preparation for the experiment and their adaptation to the problem of interpreting the results. The calculations include path loss computations, expected audio signal-to-noise ratios, and received signal strength based on orbital parameters. NPR Reactor shield calculations. The calculations were made using a new shielding computer code developed for the IBM The calculations show the thermal neutron flux, total neutron dose rate, and gamma dose rate distribution through the entire shield assembly.

The calculations show that the side and top primary shield design is adequate to reduce the radiation level below design tolerances. The radiation leakage through the front shield was higher than the design tolerances. Both of these concretes reduced the radiation below design tolerances. With this change the NPR shield is adequate according to these calculations.

The calculations reported here do not include leakage through penetration in the shield. Reconstruction de la surface de Fermi dans l'etat normal d'un supraconducteur a haute Tc: Une etude du transport electrique en champ magnetique intense. Des mesures de resistance longitudinale et de resistance de Hall en champ magnetique intense transverse perpendiculaire aux plans CuO2 ont ete effectuees au sein de monocristaux de YBa2Cu3Oy YBCO demacles, ordonnes et de grande purete, afin d'etudier l'etat fondamental des supraconducteurs a haute Tc dans le regime sous-dope.

Cette etude a ete realisee en fonction du dopage et de l'orientation du courant d'excitation J par rapport a l'axe orthorhombique b de la structure cristalline. Les mesures en champ magnetique intense revelent par suppression de la supraconductivite des oscillations magnetiques des resistances longitudinale et de Hall dans YBa2Cu 3O6. La conformite du comportement de ces oscillations quantiques au formalisme de Lifshitz-Kosevich, apporte la preuve de l'existence d'une surface de Fermi fermee a caractere quasi-2D, abritant des quasiparticules coherentes respectant la statistique de Fermi-Dirac, dans la phase pseudogap d'YBCO.

La faible frequence des oscillations quantiques, combinee avec l'etude de la partie monotone de la resistance de Hall en fonction de la temperature indique que la surface de Fermi d'YBCO sous-dope comprend une petite poche de Fermi occupee par des porteurs de charge negative. Cette particularite de la surface de Fermi dans le regime sous-dope incompatible avec les calculs de structure de bande est en fort contraste avec la structure electronique presente dans le regime surdope. Cette observation implique ainsi l'existence d'un point critique quantique dans le diagramme de phase d'YBCO, au voisinage duquel la surface de Fermi doit subir une reconstruction induite par l'etablissement d'une brisure de la symetrie de translation du reseau cristallin sous-jacent.

Enfin, l'etude en fonction du dopage de la resistance de Hall et de la resistance longitudinale en champ magnetique intense suggere qu'un ordre du type onde de densite DW est responsable de la reconstruction de la surface de Fermi. L'analogie de. Online plasma calculator.
