Caracterisation des proprietes acoustiques des materiaux poreux a cellules ouvertes et a matrice rigide ou souple  

NASA Astrophysics Data System (ADS)

L'objectif global vise par les travaux de cette these est d'ameliorer la caracterisation des proprietes macroscopiques des materiaux poreux a structure rigide ou souple par des approches inverses et indirectes basees sur des mesures acoustiques faites en tube d'impedance. La precision des approches inverses et indirectes utilisees aujourd'hui est principalement limitee par la qualite des mesures acoustiques obtenues en tube d'impedance. En consequence, cette these se penche sur quatre problemes qui aideront a l'atteinte de l'objectif global precite. Le premier probleme porte sur une caracterisation precise de la porosite ouverte des materiaux poreux. Cette propriete en est une de passage permettant de lier la mesure des proprietes dynamiques acoustiques d'un materiau poreux aux proprietes effectives de sa phase fluide decrite par les modeles semi-phenomenologiques. Le deuxieme probleme traite de l'hypothese de symetrie des materiaux poreux selon leur epaisseur ou un index et un critere sont proposes pour quantifier l'asymetrie d'un materiau. Cette hypothese est souvent source d'imprecision des methodes de caracterisation inverses et indirectes en tube d'impedance. Le critere d'asymetrie propose permet ainsi de s'assurer de l'applicabilite et de la precision de ces methodes pour un materiau donne. Le troisieme probleme vise a mieux comprendre le probleme de transmission sonore en tube d'impedance en presentant pour la premiere fois un developpement exact du probleme par decomposition d'ondes. Ce developpement permet d'etablir clairement les limites des nombreuses methodes existantes basees sur des tubes de transmission a 2, 3 ou 4 microphones. La meilleure comprehension de ce probleme de transmission est importante puisque c'est par ce type de mesures que des methodes permettent d'extraire successivement la matrice de transfert d'un materiau poreux et ses proprietes dynamiques intrinseques comme son impedance caracteristique et son nombre d'onde complexe. Enfin, le quatrieme probleme porte sur le developpement d'une nouvelle methode de transmission exacte a 3 microphones applicable a des materiaux ou systemes symetriques ou non. Dans le cas symetrique, on montre que cette approche permet une nette amelioration de la caracterisation des proprietes dynamiques intrinseques d'un materiau. Mots cles. materiaux poreux, tube d'impedance, transmission sonore, absorption sonore, impedance acoustique, symetrie, porosite, matrice de transfert.

Application de la combustion catalytique aux turbines à gaz  

NASA Astrophysics Data System (ADS)

La réduction des émissions d'oxydes d'azote sur turbines à gaz est obtenue par diminution de la température au sein de la chambre de combustion. Les techniques possibles comprennent l'injection d'eau ou de vapeur, la combustion pauvre et l'oxydation catalytique. Parmi celles-ci, la dernière est la plus prometteuse en terme de coûts et de performances, avec des émissions de NOx ramenées à un seul chiffre (typiquement inférieures à 3 ppm). L'IFP travaille depuis maintenant 10 ans sur l'adaptation de la combustion catalytique aux turbines à gaz. Les études ont été conduites au travers de projets européen tels que AGATA (Advance Gas Turbine for Automotive Application) et ULECAT (Ultra Low CATalytic combustor for dual fuel gas turbine). Le premier projet était destiné au développement de véhicules hybrides et le second à la combustion stationnaire de biogaz et de combustible Diesel. Les études en cours dans ce domaine portent sur le développement d'une unité de cogénération intégrant une microturbine à combustion catalytique. Les travaux menés à l'IFP concernent la mise au point de catalyseurs répondant aux exigences de la combustion catalytique en turbine à gaz et le développement de chambres de combustion permettant la mise en oeuvre de ces catalyseurs.

Adsorption de gaz sur les materiaux microporeux modelisation, thermodynamique et applications  

NASA Astrophysics Data System (ADS)

Nos travaux sur l'adsorption de gaz dans les materiaux microporeux s'inscrivent dans le cadre des recherches visant a augmenter l'efficacite du stockage de l'hydrogene a bord des vehicules. Notre objectif etait d'etudier la possibilite d'utiliser l'adsorption afin d'ameliorer l'efficacite de la liquefaction de l'hydrogene des systemes a petite echelle. Nous avons egalement evalue les performances d'un systeme de stockage cryogenique de l'hydrogene base sur la physisorption. Comme nous avons affaire a des plages de temperatures particulierement etendues et a de hautes pressions dans la region supercritique du gaz, nous avons du commencer par travailler sur la modelisation et la thermodynamique de l'adsorption. La representation de la quantite de gaz adsorbee en fonction de la temperature et de la pression par un modele semi-empirique est un outil utile pour determiner la masse de gaz adsorbee dans un systeme mais egalement pour calculer les effets thermiques lies a l'adsorption. Nous avons adapte le modele Dubinin-Astakhov (D-A) pour modeliser des isothermes d'adsorption d'hydrogene, d'azote et de methane sur du charbon actif a haute pression et sur une grande plage de temperatures supercritiques en considerant un volume d'adsorption invariant. Avec cinq parametres de regression (incluant le volume d'adsorption Va), le modele que nous avons developpe permet de tres bien representer des isothermes experimentales d'adsorption d'hydrogene (de 30 a 293 K, jusqu'a 6 MPa), d'azote (de 93 a 298 K, jusqu'a 6 MPa) et de methane (de 243 a 333 K, jusqu'a 9 MPa) sur le charbon actif. Nous avons calcule l'energie interne de la phase adsorbee a partir du modele en nous servant de la thermodynamique des solutions sans negliger le volume d'adsorption. Par la suite, nous avons presente les equations de conservation de la niasse et de l'energie pour un systeme d'adsorption et valide notre demarche en comparant des simulations et des tests d'adsorption et de desorption. En plus de l'energie interne, nous avons evalue l'entropie, l'energie differentielle d'adsorption et la chaleur isosterique d'adsorption. Nous avons etudie la performance d'un systeme de stockage d'hydrogene par adsorption pour les vehicules. La capacite de stockage d'hydrogene et les performances thermiques d'un reservoir de 150 L contenant du charbon actif Maxsorb MSC-30(TM) (surface specifique ˜ 3000 m2/g) ont ete etudiees sur une plage de temperatures de 60 a 298 K et a des pressions allant jusqu'a 35 MPa. Le systeme a ete considere de facon globale, sans nous attarder a un design particulier. Il est possible de stocker 5 kg d'hydrogene a des pressions de 7.8, 15.2 et 29 MPa pour des temperatures respectivement de 80, 114 et 172 K, lorsqu'on recupere l'hydrogene residuel a 2.5 bars en le chauffant. La simulation des phenomenes thermiques nous a permis d'analyser le refroidissement necessaire lors du remplissage, le chauffage lors de la decharge et le temps de dormance. Nous avons developpe un cycle de liquefaction de l'hydrogene base sur l'adsorption avec compression mecanique (ACM) et avons evalue sa faisabilite. L'objectif etait d'augmenter sensiblement l'efficacite des systemes de liquefaction de l'hydrogene a petite echelle (moins d'une tonne/jour) et ce, sans en augmenter le cout en capital. Nous avons adapte le cycle de refrigeration par ACM afin qu'il puisse par la suite etre ajoute a un cycle de liquefaction de l'hydrogene. Nous avons ensuite simule des cycles idealises de refrigeration par ACM. Meme dans ces conditions ideales, la refrigeration specifique est faible. De plus, l'efficacite theorique maximale de ces cycles de refrigeration est d'environ 20 a 30% de l'ideal. Nous avons realise experimentalement un cycle de refrigeration par ACM avec le couple azote/charbon actif. (Abstract shortened by UMI.)

Diffusion de neutrons aux petits angles : application à l'étude des macromolécules biologiques en solution  

NASA Astrophysics Data System (ADS)

La diffusion de neutrons aux petits angles (DNPA) permet de sonder les propriétés statiques de la matière sur une échelle spatiale allant de quelques dixièmes à quelques dizaines de nanomètres. Cette technique est ainsi particulièrement bien adaptée à l'étude des macromolécules en solution. Il est possible d'accéder à des grandeurs moyennes qui caractérisent la conformation qu'adoptent les macromolécules ou leurs interactions thermodynamiques. Le cours expose à des non spécialistes les différentes grandeurs mesurables et les méthodes à utiliser pour y accéder. En particulier sont abordées: 1) les mesures effectuées dans la limite du vecteur de diffusion nul qui sont liées aux fluctuations de concentration; 2) les notions de facteur de forme, de facteur de structure dots 3) les différentes façon de jouer avec le contraste. Les notions introduites sont illustrées par des exemples didactiques empruntés à la littérature et concernant des macromolécules biologiques en solution.

Application of the New Decommissioning Regulation to the Nuclear Licensed Facilities (NLF) at Fontenay-aux-Roses's Nuclear Center (CEA)  

SciTech Connect

This abstract describes the application of the new decommissioning regulation on all Nuclear Licensed Facilities (NLF is to say INB in French) at Fontenay-aux-Roses's Center (CEA/FAR). The decommissioning process has been applied in six buildings which are out of the new nuclear perimeter proposed (buildings no 7, no 40, no 94, no 39, no 52/1 and no 32) and three buildings have been reorganized (no 54, no 91 and no 53 instead of no 40 and no 94) in order to increase the space for temporary nuclear waste disposal and to reduce the internal transports of nuclear waste on the site. The advantages are the safety and radioprotection improvements and a lower operating cost. A global safety file was written in 2002 and 2003 and was sent to the French Nuclear Authority on November 2003. The list of documents required is given in the paragraph I of this paper. The main goals were two ministerial decrees (one decree for each NLF) getting the authorization to modify the NLF perimeter and to carry out cleaning and dismantling activities leading to the whole decommissioning of all NLF. Some specific authorizations were necessary to carry out the dismantling program during the decommissioning procedure. They were delivered by the French Nuclear Safety Authority (FNSA) or with limited delegation by the General Executive Director (GED) on the CEA Fontenay-aux-Roses's Center, called internal authorization. Some partial dismantling or decontamination examples are given below: - evaporator for the radioactive liquid waste treatment station (building no 53): FNSA authorization: phase realised in 2002/2003. - disposal tanks for the radioactive liquid waste treatment station (building no 53) FNSA authorization: phase realised in 2004, - incinerator for the radioactive solid waste treatment station (building no 07): FNSA authorization: operation realised in 2004, - research equipments in the building no. 54 and building no. 91: internal authorization ; realised in 2005, - sample-taking to characterize solvent contained in one tank of Petrus installation (NLF 57, building 18) for radiological and chemical analysis needed to prepare the treatment and the evacuation of these wastes : internal authorization ; realised in june 2005. It was possible to plan the whole decommissioning process on the Nuclear Licensed Facilities of Fontenay-aux-Roses's Center (CEA/FAR) taking into account the French new regulation and to plan a coherent and continue program activity for the dismantling process. For the program not to be interrupted during the administrative process (2003-2006), specific authorisations have been delivered by the French Nuclear Safety Authority or by the General Executive Director (GED) on the CEA Fontenay-aux- Roses's Center (internal authorization). The time schedule to complete the entire program is until 2017 for NLF 'Procede' (NLF no 165) and until 2018 for NLF 'Support' (NLF no 166). Since 1999, an annual press meeting has been organised by the Fontenay-aux-Roses's Center Head Executive Manager.

Application du groupe de renormalisation aux conducteurs organiques quasi-unidimensionnels soumis a un champ magnetique  

NASA Astrophysics Data System (ADS)

Des conducteurs organiques fortement anisotropes presentent, sous l'effet d'un champ magnetique, une etonnante variete de proprietes physiques tel que: l'effet Shubnikov-de Haas, l'effet de Haas-van-Alphen, l'existence de cascades d'ondes de densite de spin apparentees a l'effet Hall quantique, reentrance vers la phase metallique pouvant provenir d'un 'breakdown' magnetique, et tout recemment la possibilite d'un confinement charge induit par le champ magnetique. A cela s'ajoute les nombreuses caracteristiques deja apparues en variant la pression hydrostatique ou la substitution chimique: separation spin-charge, localisation de la charge, transition spin-Peierls, antiferromagnetisme itinerant ou non, supraconductivite, et l'existence d'une frontiere commune entre les phases supraconductrice et antiferromagnetique. En vue de completer la description theorique du diagramme de phase generalise des conducteurs organiques, nous adaptons et elargissons la methode du groupe de renormalisation quantique (GRQ) au cas ou le champ magnetique est non nul. On sait deja que cette methode permet de resoudre le dilemme tout particulier des composes Q-1D, soit leur capacite de produire des transitions de phase malgre leur forte anisotropie et consequemment de leur faible dimensionalite. Cette methode est deja utilisee pour decrire le diagramme de phase temperature versus pression des sels de Bechgaard, de leurs analogues souffres et mixtes. Le GRQ permet aussi de comprendre comment des systemes anisotropes comme les conducteurs organiques peuvent se comporter comme des liquides de Luttinger a haute temperature et comme des liquides de Fermi ou condenses a basse temperature. Nous montrons que l'introduction d'un champ magnetique dans un regime de saut coherent interchai ne a deux particules n'apporte que de simples corrections aux lois d'echelles dans le canal zero son, alors qu'il introduit un mecanisme de brisure de paire dans le canal Cooper. Dans le regime de saut coherent a une particule, la situation est plus complexe puisque la structure de bande et la forme de la surface de Fermi deviennent pertinentes. Sous bon nesting, un champ magnetique le champ magnetique defavorise les phases magnetiques du type habituellement observe en champ nul. Nous obtenons en effet que leur temperature de transition diminue avec le champ magnetique. Sous deviations au nesting suffisant pour detruire l'ordre magnetique a champ nul, nous montrons que le nesting quantifie est compatible avec l'analyse du GRQ pour des champ faibles et intermediaires. Ainsi, le nesting quantifie fournit toujours une excellente base de description des cascades de phases d'onde de densite de spin induite en champ magnetique. D'autre part, l'utilisation du GRQ permet de mettre en evidence l'existence d'un regime de champ fort. Dans ce regime le mouvement coherent des electrons dans la direction transverse aux chai ne est fortement reduit. De cette reduction de la coherence transverse les regles de renormalisation 1D qui persistent a une temperature plus basse que dans les autres regimes. Ceci donne la possibilite d'atteindre grace au champ magnetique des etats de type localisation de charge et spin-Peierls qui sont habituellement observes, en champ nul, dans des composes ayant un caractere unidimensionnel beaucoup plus prononce.

Tilt and strain deformation induced by hydrologically active natural fractures: application to the tiltmeters installed in Sainte-Croix-aux-Mines observatory (France)  

NASA Astrophysics Data System (ADS)

We investigate the deformation induced by water pressure variations in hydrologically active natural fractures, and recorded by tiltmeters and strainmeters. The deformation associated with a single fracture is derived using finite-element modelling (FEM). A range in fracture geometries is explored, first to highlight the sensitivity of each geometrical parameter to the deformation, and secondly to allow transfer to observation sites. Water level variations in the fracture are then derived from a hydrological model, driven by observed rainfall, and calibrated on fracture water flow measurements. The modelling results are explicitly applied to constrain the local hydrological contribution to observations with the 100-m-long hydrostatic tiltmeter installed at Sainte-Croix-aux-Mines (France). Our study shows that well-founded physical modelling of local hydrological effect allows a substantial correction of records in observatories.

Mecanique et mecanisme de la dechirure des materiaux textiles  

NASA Astrophysics Data System (ADS)

Cette thèse vise à apporter une contribution à l’étude et à la modélisation de la déchirure des textiles et des textiles enduits. Notons que la résistance à la déchirure est l’une des caractéristiques mesurées pour les équipements de protection contre les agresseurs mécaniques en milieu de travail. Jusqu'à présent, ce comportement en déchirure a été étudié en mesurant la force de déchirure et le travail de déchirure. De fait, aucun critère de rupture en déchirure n’existe actuellement. Par conséquent, en s’inspirant de la théorie du Griffith et de la mécanique de la rupture, une formulation d’un nouveau critère de rupture des structures textiles a été proposée. Cette approche offre la possibilité de déterminer d’une manière plus précise l’énergie nécessaire pour la création d’une nouvelle surface de rupture. Ce critère nous permet d’analyser l’effet des caractéristiques des tissus sur la variation de l’énergie de rupture. Cette étude montre que la résistance au glissement des fils dans la structure est le principal facteur qui contrôle la propagation de la fissure. En se basant sur la théorie de la mécanique de la rupture, un modèle de calcul de l’énergie de rupture par déchirure a été aussi élaboré. Ce modèle de déchirure relie l’énergie aux paramètres caractérisant les phénomènes affectant la déchirure des tissus, notamment la force de glissement et la force à la rupture des fils. Cette modélisation a tenu compte de certaines caractéristiques des tissus tels que l’épaisseur du matériau, la densité des fils, etc. Par l’étude de la variation de l’énergie de rupture par déchirure en fonction du rapport établi entre la force à la rupture et la force de glissement d’un fil ( FYB/FS), l’effet des mécanismes de la propagation de la fissure dans les tissus sur leur comportement en déchirure a été aussi observé. Les résultats obtenus permettent de distinguer deux différentes catégories de déchirure. Pour les basses densités des fils, la fissure se propage dans le tissu par glissement des fils, alors que pour les hautes densités des fils, la déchirure est obtenue par la rupture des fils. Ainsi, il est important de noter que l’énergie de rupture par déchirure des tissus est maximale lorsque le rapport FYB/FS est proche de l’unité. En ce qui a trait à la déchirure des textiles enduits, la propagation de la fissure est obtenue par déchirure du support textile et de l’enduit de manière simultanée ainsi que par le délaminage du système textile-enduit. La définition d’un critère de rupture pour les textiles enduits nous a permis de constater que l’enduction d’un support textile par une couche d’élastomère engendre une diminution de son énergie de rupture. En outre, l’étude de la déchirure du support textile, de l’enduit et des textiles enduits a montré que l’énergie obtenue pour la couche de l’enduit est très faible si nous la comparons avec celles du support textile et du textile enduit. L’étude de l’effet du vieillissement sur l’énergie de rupture par déchirure a aussi fait l’objet de cette thèse. L’exposition des textiles enduits à différentes températures de vieillissement montre que le comportement en déchirure des textiles et des textiles enduits est similaire pour les durées les plus faibles. Par contre, une accélération de la réduction de la résistance à la déchirure est observée pour les textiles enduits aux temps de vieillissement plus élevés. Ce phénomène peut éventuellement être attribué à une augmentation de l’adhésion du système textile-enduit suite au traitement de vieillissement. La diminution de la mobilité des fils ainsi engendrée cause alors une importante chute de la valeur de l’énergie de rupture par déchirure. Mots clés : Textiles, Textiles enduits, Énergie de rupture, Modélisation, Vieillissement thermique.

Maladies reli?es aux loisirs aquatiques  

PubMed Central

Résumé Objectif Passer en revue les facteurs de risque, la prise en charge et la prévention des maladies reliées aux loisirs aquatiques en pratique familiale. Sources des données Des articles originaux et de synthèse entre janvier 1998 et février 2012 ont été identifiés à l’aide de PubMed et des expressions de recherche en anglais water-related illness, recreational water illness et swimmer illness. Message principal Il y a un risque de 3 % à 8 % de maladies gastrointestinales (MGI) après la baignade. Les groupes à risque élevé de MGI sont les enfants de moins de 5 ans, surtout s’ils n’ont pas été vaccinés contre le rotavirus, les personnes âgées et les patients immunodéficients. Les enfants sont à plus grand risque parce qu’ils avalent plus d’eau quand ils nagent, restent dans l’eau plus longtemps et jouent dans l’eau peu profonde et le sable qui sont plus contaminés. Les adeptes des sports dans lesquels le contact avec l’eau est abondant comme le triathlon et le surf cerf-volant sont aussi à risque élevé et même ceux qui s’adonnent à des activités impliquant un contact partiel avec l’eau comme la navigation de plaisance et la pêche ont un risque de 40 % à 50 % fois plus grand de MGI par rapport à ceux qui ne pratiquent pas de sports aquatiques. Il y a lieu de faire une culture des selles quand on soupçonne une maladie reliée aux loisirs aquatiques et l’échelle clinique de la déshydratation est utile pour l’évaluation des besoins de traitement chez les enfants affectés. Conclusion Les maladies reliées aux loisirs aquatiques est la principale cause de MGI durant la saison des baignades. La reconnaissance que la baignade est une source importante de maladies peut aider à prévenir les cas récurrents et secondaires. On recommande fortement le vaccin contre le rotavirus chez les enfants qui se baignent souvent.

Comportement de frittés et de films d'oxyde de titane en présence d'atmosphères gazeuses, hors équilibre thermodynamique, en régime stationnaire; application aux capteurs résistifs d'oxygène  

NASA Astrophysics Data System (ADS)

Oxygen resistive titanium dioxide sensors are useful to control combustion but their studies raise fundamental problems. The non-stoichiometry of titanium dioxide is studied in the 870-1 100 K temperature range by using, out of equilibrium, gas mixture flow of CO, CO2, O2 and Ar. The electrical resistance of sintered samples (dense or porous) or films is measured in steady-state conditions as a function of th gaz flow rate. The deviation to equilibrium increases with the flow rate. The sample resistance is a function of the flow rate, oxygen partial pressure, temperature and microstructure of the specimen. The sensitivity to oxygen is increased by fast oxygen diffusion through the bulk creating a potential barrier at the surface of the grains. Under oxidizing conditions at 870 K, a bulk mechanism determines the resistance variation which is proportional to P_{O_2}^{1/4}/P_{CO}^{1/2}. If reducing conditions are applied, in the same conditions of temperature, the oxide develops a bulk non-stoichiometry which is controlled by the redox couple CO/CO2 assuming thermodynamical equilibrium. However the large number of conducting electrons favors an oxygen chemisorption, creating potential barriers at the surface of the grains. Accordingly the film resistance is a P_{O_2}^{1/2} function. The surface potential and coverage rate are calculated through several theoretical models ; their comparison allows to conclude in a relatively slow diffusion of oxygen vacancies at 870 K. At 1 100 K, the gaz mixture is rather close to thermodynamical equilibrium : in oxidizing medium the sample is equilibrated with oxygen, under CO/CO2 reducing conditions film sensors are only sensitive to oxygen traces. La non-stœchiométrie de l'oxyde de titane est étudiée, dans le domaine de température 870-1 100 K, en présence d'atmosphères hors équilibre thermodynamique, composées de CO, CO2, O2, Ar. La résistance électrique de différentes structures massives, poreuses ou en couches est mesurée, en régime stationnaire, en fonction du débit des gaz ; ces atmosphères sont d'autant plus éloignées de l'équilibre que le débit est élevé. On montre que les variations de résistance des échantillons, en fonction du débit, dépendent du domaine de pression partielle d'oxygène, de la température et de la structure des échantillons. La sensibilité à l'oxygène est accrue par un morphologie qui, à l'échelle macroscopique, favorise la diffusion de l'oxygène et qui, à l'échelle microscopique, permet la création de barrière de potentiel aux joints de grains. En milieu oxydant, à 870 K, un mécanisme de volume qui met en jeu la cinétique des échanges avec la phase gazeuse, détermine une variation de résistance en P_{O_2}^{1/4}/P_{CO}^{1/2}. En milieu réducteur, à la même température, la non-stœchiométrie en volume de l'oxyde est fixée par le couple redox CO/CO2 comme si l'atmosphère était en équilibre thermodynamique. Mais l'abondance des électrons de conduction, favorise la chimisorption de l'oxygène qui contrôle la résistance des couches selon une loi en P_{O_2}^{1/2} en créant des barrières de potentiel à la surface des grains. Des modèles, permettant le calcul du potentiel de surface ainsi que du taux de recouvrement, sont développés ; la comparaison des modèles indique une diffusion relativement lente des lacunes d'oxygène à 870 K. A 1 100 K, l'atmosphère tend à être à l'équilibre thermodynamique : i) en atmosphère oxydante, tous les capteurs sont en équilibre avec la pression partielle d'oxygène ; ii) en atmosphère réductrice, dominée par le couple redox CO/CO2, seules les couches sont sensibles à la présence de traces d'oxygène.

Preliminary paleogeographic reconstruction of the Illinois basin during deposition of the Mississippian Aux Vases Formation: Implications for hydrocarbon recovery  

SciTech Connect

Extensive outcrop investigation and selective subsurface study allow definition of Illinois basin paleogeography during deposition of the Mississippian (Valmeyeran-Meramecian) Aux Vases Formation. The results incorporate an integrated approach utilizing field observations and petrographic analysis, wireline logs, subsurface maps, and cores. The Aux Vases Formation depositional system has been determined to be composed of subtidal to intertidal facies. Depositional facies in outcrop are based on rock body geometries, sedimentary structure assemblages, paleocurrent analysis, paleontology of body and trace fossils, facies relationships, and petrography. Depositional facies determined from subsurface data are based on correlation of lithologic interpretations from wireline logs, sand body geometries form isopach maps, and petrography. Specific depositional facies observed in outcrop and core and inferred from wireline logs and isopach maps are offshore bars and tidal channel complexes, extensive subtidal to lower intertidal, ripple-laminated, fine-grained quartzose sandstone. Carbonate facies occur as subtidal grainstones at or near the base of a sequence, or as high energy deposits which have been tidally reworked. This depositional system produces reservoir heterogeneities that complicate efficient hydrocarbon recovery. This diverse facies architecture is modified by tectonic and diagenetic overprinting, further segregating potential producing zones. To significantly improve recovery efficiency, predictions regarding compartmentalization can be used prior to designing a drilling program, an infill drilling program, or an application of enhanced recovery techniques.

Symetries et integrabilite des equations aux differences finies  

NASA Astrophysics Data System (ADS)

La présente thèse porte sur l'étude des symétries et des propriétés d'intégrabilité des équations aux différences finies. Dans le chapitre 1, le groupe de symétrie ponctuelle d'un système couplé à deux équations différentielles aux différences est étudié. On montre que dans certains cas, la dimension du groupe peut être infinie. Les équations peuvent décrire l'interaction de deux longues chaînes moléculaires, chacune étant composée d'atomes d'un même type. Dans le chapitre 2, une classe de théories de champs avec interaction exponentielle est introduite. L'interaction dépend de deux matrices de ``couplage'' et est suffisamment générale pour inclure toutes les théories de champs de Toda existant dans la littérature. Les symétries de Lie ponctuelles sont obtenues pour les cas où l'on a un nombre fini, infini ou semi-infini de champs. Une attention spéciale est accordée à la présence de l'invariance conforme. Dans le chapitre 3, nous procédons à la classification et à l'étude d'équations linéarisables. Nous examinons tout d'abord l'équation de Gambier continue qui contient, comme réductions, toutes les équations de deuxième ordre intégrables par linéarisation. Nous introduisons par la suite la forme discrète de cette équation et obtenons les conditions d'intégrabilité à l'aide du confinement des singularités. Nous étudions aussi les différentes réductions du cas discret. De plus, nous obtenons des transformations de Schlesinger pour les équations de Gambier discrète et continue. Dans la dernière partie du chapitre, nous étudions une famille d'équations discrètes du deuxième ordre incluant des équations résolubles par linéarisation. Plusieurs cas intégrables sont obtenus. Dans le cas discret, l'étude de l'intégrabilité est faite à l'aide du confinement des singularités. Dans le chapitre 4, nous étudions un autre critère d'intégrabilité: l'entropie algébrique. Nous montrons que les résultats obtenus avec ce critère pour les équations linéarisables sont les mêmes que ceux obtenus avec le confinement des singularités. Nous obtenons de plus une méthode algorithmique pour la détection de la linéarisabilité. Le chapitre 5 est consacré à l'étude d'équations du troisième ordre. Nous obtenons des équations intégrables par des couplages d'équations du premier et du deuxième ordre. Les équations continues sont étudiées à l'aide de l'analyse de Painlevé et le confinement des singularités est utilisé dans le cas discret.

Arabidopsis aux1rcr1 mutation alters AUXIN RESISTANT1 targeting and prevents expression of the auxin reporter DR5:GUS in the root apex  

PubMed Central

Multilevel interactions of the plant hormones ethylene and auxin coordinately and synergistically regulate many aspects of plant growth and development. This study isolated the AUXIN RESISTANT1 (AUX1) allele aux1rcr1 (RCR1 for REVERSING CTR1-10 ROOT1) that suppressed the root growth inhibition conferred by the constitutive ethylene-response constitutive triple response1-10 (ctr1-10) allele. The aux1rcr1 mutation resulted from an L126F substitution at loop 2 of the plasma membrane-associated auxin influx carrier protein AUX1. aux1rcr1 and the T-DNA insertion mutant aux1-T were both defective in auxin transport and many aspects of the auxin response. Unexpectedly, expression of the auxin-response reporter DR5:GUS in the root apex was substantially prevented by the aux1rcr1 but not the aux1-T mutation, even in the presence of the wild-type AUX1 allele. Following treatment with the synthetic auxin 1-naphthaleneacetic acid (NAA), DR5:GUS expression in aux1rcr1 and aux1-T occurred mainly in the root apex and mature zone. NAA-induced DR5:GUS expression in the root apex was markedly prevented by ethylene in genotypes with aux1rcr1 but not in aux1-T genotypes and the wild type. The effect of aux1rcr1 on DR5:GUS expression seemed to be associated with AUX1-expressing domains. Green fluorescence protein-fused aux1rcr1 was localized in the cytoplasm and probably not to the plasma membrane, indicating important roles of the Lys126 residue at loop 2 in AUX1 targeting. The possible effects of aux1rcr1 on DR5:GUS expression are discussed.

Yokonolide B, a novel inhibitor of auxin action, blocks degradation of AUX/IAA factors.  

PubMed

Yokonolide B (YkB; also known as A82548A), a spiroketal-macrolide, was isolated from Streptomyces diastatochromogenes B59 in a screen for inhibitors of beta-glucoronidase expression under the control of an auxin-responsive promoter in Arabidopsis. YkB inhibits the expression of auxin-inducible genes as shown using native and synthetic auxin promoters as well as using expression profiling of 8300 Arabidopsis gene probes but does not affect expression of an abscisic acid- and a gibberellin A3-inducible gene. The mechanism of action of YkB is to block AUX/IAA protein degradation; however, YkB is not a general proteasome inhibitor. YkB blocks auxin-dependent cell division and auxin-regulated epinastic growth mediated by auxin-binding protein 1. Gain of function mutants such as shy2-2, slr1, and axr2-1 encoding AUX/IAA transcriptional repressors and loss of function mutants encoding components of the ubiquitin-proteolytic pathway such as axr1-3 and tir1-1, which display increased AUX/IAAs protein stability, are less sensitive to YkB, although axr1 and tir1 mutants were sensitive to MG132, a general proteasome inhibitor, consistent with a site of action downstream of AXR1 and TIR. YkB-treated seedlings displayed similar phenotypes as dominant AUX/IAA mutants. Taken together, these results indicate that YkB acts to block AUX/IAA protein degradation upstream of AXR and TIR, links a shared element upstream of AUX/IAA protein stability to auxin-induced cell division/elongation and to auxin-binding protein 1, and provides a new tool to dissect auxin signal transduction.

Comprendre les representations du personnel soignant face aux infections nosocomiales au Clostridium difficile au Quebec pour mieux en promouvoir la sante.  

PubMed

Au cours des dernières années, la transmission des infections nosocomiales, notamment des infections à Clostridium difficile, est devenue une importante préoccupation au Québec. Pour éviter leur transmission, les experts recommandent notamment la formation du personnel. Dans cet article, nous décrivons la représentation que se font certaines catégories de personnel de la santé à propos des risques reliés à la transmission du Clostridium difficile et leur perception des messages de prévention, afin d'identifier des avenues permettant de contribuer à cette formation. Nous avons effectué 27 entrevues et 186 heures d'observation auprès d'infirmières, infirmières auxiliaires, préposés aux bénéficiaires et préposés à l'entretien sanitaire expérimentés, dans deux unités de soins de courte durée et deux de longue durée d'un hôpital à Montréal. Résultats : le personnel se préoccupe de la transmission du C difficile envers les patients et envers leurs propres familles davantage que des conséquences immédiates sur leur propre santé. Les pratiques pour éviter de transporter le microorganisme à leur maison sont décrites. Malgré l'application de mesures de prévention, certains participants pensent s'être contaminés et être porteurs sains du C difficile, qui persisterait dans leur organisme et pourrait s'activer s'ils sont affaiblis ou sous antibiotiques. Cette contamination surviendrait à cause de situations mettant en échec la prévention : les patients non diagnostiqués et les délais de diagnostic, un manque de formation sur les mesures de prévention et sur les mesures pratiques pour les appliquer et un manque d'information sur les produits désinfectants, ces deux dernières mesures affectant surtout les préposées aux bénéficiaires. Nous concluons sur la nécessité de prendre en compte les préoccupations du personnel dans les interventions éducatives ; de formations pratiques, adaptées au travail et sur le besoin d'information quant aux raisons de changements de produits.

A DFT study of the structures of Au(x) clusters on a CeO2(111) surface.  

PubMed

Studying the structures of metal clusters on oxide supports is challenging due to their various structural possibilities. In the present work, a simple rule in which the number of Au atoms in different layers of Au(x) clusters is changed successively is used to systematically investigate the structures of Au(x) (x=1-10) clusters on stoichiometric and partially reduced CeO(2)(111) surface by DFT calculations. The calculations indicate that the adsorption energy of a single Au atom on the surface, the surface structure, as well as the Au-Au bond strength and arrangement play the key roles in determining Au(x) structures on CeO(2)(111). The most stable Au(2) and Au(3) clusters on CeO(2)(111) are 2D vertical structures, while the most stable structures of Au(x) clusters (x>3) are generally 3D structures, except for Au(7). The 3D structures of large Au(x) clusters in which the Au number in the bottom layer does not exceed that in the top layer are not stable. The differences between Au(x) on CeO(2)(111) and Mg(100) were also studied.

The diageotropica (dgt) mutation has been proposed to affect either auxin perception or responsiveness in tomato plants. It has previously been demonstrated that the expression of one member of the Aux\\/IAA family of auxin-regulated genes is reduced in dgt plants. Here, we report the cloning of ten new members of the tomato Aux\\/IAA family by PCR amplification based on conserved

Genome-wide analysis of Aux/IAA and ARF gene families in Populus trichocarpa  

SciTech Connect

Auxin/Indole-3-Acetic Acid (Aux/IAA) and Auxin Response Factor (ARF) transcription factors are key regulators of auxin responses in plants. A total of 35 Aux/IAA and 39 ARF genes were identified in the Populus genome. Comparative phylogenetic analysis revealed that the subgroups PoptrARF2, 6, 9 and 16 and PoptrIAA3, 16, 27 and 29 have differentially expanded in Populus relative to Arabidopsis. Activator ARFs were found to be two fold-overrepresented in the Populus genome. PoptrIAA and PoptrARF gene families appear to have expanded due to high segmental and low tandem duplication events. Furthermore, expression studies showed that genes in the expanded PoptrIAA3 subgroup display differential expression. The gene-family analysis reported here will be useful in conducting future functional genomics studies to understand how the molecular roles of these large gene families translate into a diversity of biologically meaningful auxin effects.

The Morne Aux Diables volcano, Dominica, Lesser Antilles: A stratigraphic and petrologic study.  

NASA Astrophysics Data System (ADS)

Morne Aux Diables is a topographically distinct stratovolcano located at the northernmost end of the island of Dominica, Lesser Antilles. In 2007, observations were conducted, and over 3,000 digital photographs were taken, of the well-exposed sea cliffs around Dominica. These observations, together with photogeological analysis of approximately 500 of these digital photographs of sea cliffs around the northern part of Dominica, have significantly improved our understanding of the geology of Morne aux Diables volcano, which previously had been based on scattered land exposures. The photographs were used to identify genetic packages of strata related to volcanogenic events and trace them around large sectors of the volcano's flanks. Based on these new studies, together with previous data, Morne aux Diables appears to have undergone two periods of activity, an older period dated between 2.1-1.5 Ma and a younger period dated at around 50,000 years B.P. Deposits associated with the older cone-forming activity are primarily composed of block and ash flows and surges associated with Pelean-style activity. These can be subdivided into a number of sequences based on the presence of paleosols. Domes associated with these eruptions are found both in the central vent area as well as around the flanks of the volcano. The upper deposits in the sea cliffs on the eastern, northern and western flanks are a thick sequence of surges that have been provisionally correlated with a well-exposed sequence of semi-vesicular block and ash flows and surge deposits at Morne a Louis on the west coast. The presence of these surge deposits at the top of the sea cliffs suggests that the older period of activity ended with open-crater Asama-style eruptions. Following an extensive quiescent period, renewed Pelean-style activity produced valley-fill block and ash flow and surge deposits, exposed on both the eastern and western sides of the volcano, together with associated domes (both central and parasitic). Petrographic studies show that Morne Aux Diables volcano is composed of andesites and dacites with a mineral assemblage of plagioclase+augite±hypersthene with minor hornblende and quartz. Geochemically both the older and younger volcanic rocks show trends, especially in terms of alkalis, that are slightly lower and cross- cut from those shown by the other centers on Dominica. These stratigraphic and petrologic studies will help further elucidate the volcanic history of Morne aux Diables and allow a petrologic-stratigraphic model of its formation.

Aux1p/Swa2p Is Required for Cortical Endoplasmic Reticulum Inheritance in Saccharomyces cerevisiae  

PubMed Central

In the yeast Saccharomyces cerevisiae, the endoplasmic reticulum (ER) is found at the periphery of the cell and around the nucleus. The segregation of ER through the mother-bud neck may occur by more than one mechanism because perinuclear, but not peripheral ER, requires microtubules for this event. To identify genes whose products are required for cortical ER inheritance, we have used a Tn3-based transposon library to mutagenize cells expressing a green fluorescent protein-tagged ER marker protein (Hmg1p). This approach has revealed that AUX1/SWA2 plays a role in ER inheritance. The COOH terminus of Aux1p/Swa2p contains a J-domain that is highly related to the J-domain of auxilin, which stimulates the uncoating of clathrin-coated vesicles. Deletion of the J-domain of Aux1p/Swa2p leads to vacuole fragmentation and membrane accumulation but does not affect the migration of peripheral ER into daughter cells. These findings suggest that Aux1p/Swa2p may be a bifunctional protein with roles in membrane traffic and cortical ER inheritance. In support of this hypothesis, we find that Aux1p/Swa2p localizes to ER membranes.

Morne aux Diables. a potentially active volcano in northern Dominica, Lesser Antilles  

NASA Astrophysics Data System (ADS)

The island of Dominica, which is located near the center of the Lesser Antilles island arc, comprises at least 8 potentially active volcanoes. One of these is Morne aux Diables, an isolated composite cone situated at the extreme northern end of the island. Age dating suggests that the main cone building activity occurred between 1.5 and 1.0 million years ago. Exposed on the volcano's flanks however are a number of unconsolidated valley-fill block and ash flow deposits suggesting more recent activity. One of these deposits, on the north-east flank of the volcano, has been recently dated at > 46,000 years B.P. Other evidence of potential activity from this center includes the presence of warm (27°C), acidic (pH 1.6), sulfate-rich springs on the summit of the volcano, hot springs on the coast, and the occurrence in 2002 and 2003 of shallow earthquake swarms partially located beneath the volcano. Morne aux Diables is dominantly composed of deposits of block and ash flows and associated domes from Pelean-style activity, however, semi-vesicular andesite block and ash flows and surges (Asama-style activity) and pumiceous lapilli falls (Plinian-style activity) are locally abundant. The Pelean domes are located both in the summit region and along the southern flanks of the volcano. Petrologically, the volcano is composed of a monotonous series of porphyritic andesites and dacites containing phenocrysts of plagioclase+augite-hypersthene with very sparse crystals of hornblende and quartz. Petrological models suggest the Morne aux Diables andesites and dacites can be produced by fractional crystallization of basaltic magma (such as those erupted from centers such as Morne Anglais and Morne Plat Pays in the south). Minor variations within this suite of andesites and dacites can be related to upper crustal fractionation of phenocryst phases.

Résumé Objectif Mettre à jour les lignes directrices canadiennes de 2006 sur les soins primaires aux adultes ayant une déficience développementale (DD) et présenter des recommandations pratiques fondées sur les connaissances actuelles pour traiter des problèmes de santé particuliers chez des adultes ayant une DD. Qualité des preuves Des professionnels de la santé expérimentés participant à un colloque et un groupe de travail subséquent ont discuté et convenu des révisions aux lignes directrices de 2006 en se fondant sur une recherche documentaire exhaustive, la rétroaction obtenue des utilisateurs du guide de pratique et les expériences cliniques personnelles. La plupart des preuves disponibles dans ce domaine viennent de l’opinion d’experts ou de déclarations consensuelles publiées (niveau III). Message principal Les adultes ayant une DD ont des problèmes de santé complexes, dont plusieurs diffèrent de ceux de la population en général. De bons soins primaires permettent d’identifier les problèmes de santé particuliers dont souffrent les adultes ayant une DD pour améliorer leur qualité de vie et leur accès aux soins de santé et prévenir la morbidité et le décès prématuré. Ces lignes directrices résument les problèmes de santé générale, physique, comportementale et mentale des adultes ayant une DD que devraient connaître les professionnels des soins primaires et présentent des recommandations pour le dépistage et la prise en charge en se basant sur les connaissances actuelles que les cliniciens peuvent mettre en pratique. En raison de l’interaction des facteurs biologiques, psychoaffectifs et sociaux qui contribuent à la santé et au bien-être des adultes ayant une DD, ces lignes directrices insistent sur la participation des aidants, l’adaptation des interventions, au besoin, et la consultation auprès de divers professionnels de la santé quand ils sont accessibles. Elles mettent aussi en évidence la nature éthique des soins. Les lignes directrices sont formulées dans le contexte d’un cadre éthique qui tient compte des questions comme le consentement éclairé et l’évaluation des bienfaits pour la santé par rapport aux risques de préjudice. Conclusion La mise en œuvre des lignes directrices proposées ici améliorerait la santé des adultes ayant une DD et minimiserait les disparités sur les plans de la santé et des soins de santé entre les adultes ayant une DD et la population en général.

Le silicium nanoporeux: microstructuration diélectrique et application aux structures photoniques avancées  

NASA Astrophysics Data System (ADS)

The aim of this work is to elaborate and study photonic bandgap microstructures using nanoporous silicon. Planar microstructures like microcavities are first considered, and their influence on both angular and spectral distributions of photoluminescence are investigated. The primary conclusion derived from these studies is that it is essential to control the propagation of light in the plane, too. Thus, the lateral propagation of light, enhanced by a vertical structuring of the optical index (step-index waveguide as well as Bragg reflection waveguide) is studied. Furthermore, a numerical model based on the standard transfer-matrix method is suggested to calculate guiding losses. Finally, a holographic process is utilized to obtain a lateral structuring of the optical index, thereby allowing the investigation of its effects on the guided light. The transmittance, measured on a multimode waveguide using white light, shows several stopbands, which are attributed to diagonal and off-diagonal couplings. The comparison of these measurements to the coupled-mode theory allows a map of the optical index to be plotted. A strong birefringence in regions that were illuminated during the holographic process was illustrated. This suggests a stronger decrease of the extraordinary index (? n = -0.4) than the ordinary index (? n = -0.22). With a period of 450 nm, these values of index contrast are promising, even if the effective depth on which the index is modulated is only 0.5 ?m. Ce travail est consacré à la réalisation et à l'étude de microstructures photoniques à base de silicium nanoporeux. Nous commençons notre étude par des structures planaires de type microcavité, dont nous caractérisons l'influence sur la photoluminescence du matériau, en termes de redistribution spectrale et angulaire. Il apparaît très vite la nécessité de contrôler la propagation de la lumière dans le plan de la structure. Aussi, nous cherchons d'abord à favoriser la propagation latérale au moyen d'une structuration verticale de l'indice, et nous étudions le guidage au moyen de deux types de structures, exploitant soit à un guidage conventionnel par réflexion totale interne, soit à un guidage par réflexion de Bragg. À cette occasion nous proposons une méthode numérique, basée sur le formalisme des matrices de transfert, permettant de calculer l'atténuation de la puissance transportée dans le plan. Par la suite, nous mettons à profit le procédé holographique de structuration d'indice démontré par des travaux antérieurs et étudions son influence sur la lumière guidée. La transmission, mesurée en lumière blanche sur un guide multimode révèle de multiples bandes interdites que nous interprétons en termes de couplages diagonaux et non diagonaux. La confrontation des mesures avec une modélisation par la méthode des modes couplés nous permet d'établir une carte d'indice de notre structure. Il apparaît une biréfringence marquée dans les régions insolées par le procédé holographique, caractérisées par une diminution deux fois plus importante de l'indice extraordinaire (? n =-0{,}4) que de l'indice ordinaire (? n =-0{,}22). Avec une période de 450 nm, ces valeurs de contraste sont encourageantes, bien que la modulation d'indice ne soit présente que sur une profondeur effective de l'ordre de 0,5 ?m.

Comportement dynamique d'alliages a memoire de forme et application aux composites-AMF  

NASA Astrophysics Data System (ADS)

Meeting current industrial, governmental and international standards regarding vibration and noise levels is a challenging task facing many engineers. These specifications are present in just about all fields of engineering, from aerospace to marine transportation, from automotive to railway transportation, from computer equipment to industrial working environments. An appropriate use of the remarkable properties of high damping metals (HIDAMETS) and shape memory alloy (SMA) reinforced composites emerges as a possible solution to these problems. Among many obstacles to overcome in developing such a technology, the implementation of reliable and adequate characterization techniques to determine dynamic properties of these materials appears to be of prime importance. The research efforts presented in this thesis are aimed at developing advanced techniques to characterize the dynamic behavior of HIDAMETS and SMA reinforced composites. These characterization results lead to the enhancement of numerical (finite element) and/or analytical methods for the simulation of dynamic responses of structures made of these materials. In particular, the research work has focused on three themes: the numerical and experimental validation of applying a characterization procedure developed for traditional composites to SMA reinforced composites; the development of a test bench for uniaxial hysteresis characterization of HIDAMETS in the medium frequency range; the hysteresis characterization and modeling of manganese copper (MnCu) and nickel titanium samples. The results obtained in the course of these efforts show that the characterization technique developed for traditional composites at the University of Brussels is sufficiently precise to successfully predict natural frequencies of complex SMA reinforced composite structures. Using the characterization to predict structural damping ratios, we observe a bias error in the prediction with respect to experimental results although the relative values between modes are consistent. Regarding the development of the test bench for uniaxial hysteresis characterization of HIDAMETS, results suggest that with the introduction of a few minor enhancements and with particular experimental precautions, the test bench can play an important role in characterizing HIDAMETS dynamic properties at various frequencies and strain amplitudes and in understanding micro mechanical mechanisms responsible for energy dissipation. Finally, uniaxial hysteresis loops and related parameters have been obtained with MnCu and NiTi samples. A material model based on dual kriging interpolation that expresses the tangent stiffness along these hysteresis loops as a function of strain and strain amplitude has also been developed.

The Tomato Aux/IAA Transcription Factor IAA9 Is Involved in Fruit Development and Leaf MorphogenesisW?  

PubMed Central

Auxin/indole-3-acetic acid (Aux/IAA) proteins are transcriptional regulators that mediate many aspects of plant responses to auxin. While functions of most Aux/IAAs have been defined mainly by gain-of-function mutant alleles in Arabidopsis thaliana, phenotypes associated with loss-of-function mutations have been scarce and subtle. We report here that the downregulation of IAA9, a tomato (Solanum lycopersicum) gene from a distinct subfamily of Aux/IAA genes, results in a pleiotropic phenotype, consistent with its ubiquitous expression pattern. IAA9-inhibited lines have simple leaves instead of wild-type compound leaves, and fruit development is triggered before fertilization, giving rise to parthenocarpy. This indicates that IAA9 is a key mediator of leaf morphogenesis and fruit set. In addition, antisense plants displayed auxin-related growth alterations, including enhanced hypocotyl/stem elongation, increased leaf vascularization, and reduced apical dominance. Auxin dose–response assays revealed that IAA9 downregulated lines were hypersensitive to auxin, although the only early auxin-responsive gene that was found to be upregulated in the antisense lines was IAA3. The activity of the IAA3 promoter was stimulated in the IAA9 antisense genetic background, indicating that IAA9 acts in planta as a transcriptional repressor of auxin signaling. While no mutation in any member of subfamily IV has been reported to date, the phenotypes associated with the downregulation of IAA9 reveal distinct and novel roles for members of the Aux/IAA gene family.

Modelisation de la diffusion sur les surfaces metalliques: De l'adatome aux processus de croissance  

NASA Astrophysics Data System (ADS)

Cette these est consacree a l'etude des processus de diffusion en surface dans le but ultime de comprendre, et de modeliser, la croissance d'une couche mince. L'importance de bien mai triser la croissance est primordiale compte tenu de son role dans la miniaturisation des circuits electroniques. Nous etudions ici les surface des metaux nobles et de ceux de la fin de la serie de transition. Dans un premier temps, nous nous interessons a la diffusion d'un simple adatome sur une surface metallique. Nous avons, entre autres, mis en evidence l'apparition d'une correlation entre evenements successifs lorsque la temperature est comparable a la barriere de diffusion, i.e., la diffusion ne peut pas etre associee a une marche aleatoire. Nous proposons un modele phenomenologique simple qui reproduit bien les resultats des simulations. Ces calculs nous ont aussi permis de montrer que la diffusion obeit a la loi de Meyer-Neldel. Cette loi stipule que, pour un processus active, le prefacteur augmente exponentiellement avec la barriere. En plus, ce travail permet de clarifier l'origine physique de cette loi. En comparant les resultats dynamiques aux resultats statiques, on se rend compte que la barriere extraite des calculs dynamiques est essentiellement la meme que celle obtenue par une approche statique, beaucoup plus simple. On peut donc obtenir cette barriere a l'aide de methodes plus precises, i.e., ab initio, comme la theorie de la fonctionnelle de la densite, qui sont aussi malheureusement beaucoup plus lourdes. C'est ce que nous avons fait pour plusieurs systemes metalliques. Nos resultats avec cette derniere approche se comparent tres bien aux resultats experimentaux. Nous nous sommes attardes plus longuement a la surface (111) du platine. Cette surface regorge de particularites interessantes, comme la forme d'equilibre non-hexagonale des i lots et deux sites d'adsorption differents pour l'adatome. De plus, des calculs ab initio precedents n'ont pas reussi a confirmer la forme d'equilibre et surestiment grandement la barriere. Nos calculs, plus complets et dans un formalisme mieux adapte a ce genre de probleme, predisent correctement la forme d'equilibre, qui est en fait due a un relachement different du stress de surface aux deux types de marches qui forment les cotes des i lots. Notre valeur pour la barriere est aussi fortement diminuee lorsqu'on relaxe les forces sur les atomes de la surface, amenant le resultat theorique beaucoup plus pres de la valeur experimentale. Nos calculs pour le cuivre demontre en effet que la diffusion de petits i lots pendant la croissance ne peut pas etre negligee dans ce cas, mettant en doute la valeur des interpretations des mesures experimentales.

Phloem-specific expression of a melon Aux/IAA in tomato plants alters auxin sensitivity and plant development.  

PubMed

Phloem sap contains a large repertoire of macromolecules in addition to sugars, amino acids, growth substances and ions. The transcription profile of melon phloem sap contains over 1000 mRNA molecules, most of them associated with signal transduction, transcriptional control, and stress and defense responses. Heterografting experiments have established the long-distance trafficking of numerous mRNA molecules. Interestingly, several trafficking transcripts are involved in the auxin response, including two molecules coding for auxin/indole acetic acid (Aux/IAA). To further explore the biological role of the melon Aux/IAA transcript CmF-308 in the vascular tissue, a cassette containing the coding sequence of this gene under a phloem-specific promoter was introduced into tomato plants. The number of lateral roots was significantly higher in transgenic plants expressing CmF-308 under the AtSUC2 promoter than in controls. A similar effect on root development was obtained after transient expression of CmF-308 in source leaves of N. benthamiana plants. An auxin-response assay showed that CmF-308-transgenic roots are more sensitive to auxin than control roots. In addition to the altered root development, phloem-specific expression of CmF-308 resulted in shorter plants, a higher number of lateral shoots and delayed flowering, a phenotype resembling reduced apical dominance. In contrast to the root response, cotyledons of the transgenic plants were less sensitive to auxin than control cotyledons. The reduced auxin sensitivity in the shoot tissue was confirmed by lower relative expression of several Aux/IAA genes in leaves and an increase in the relative expression of a cytokinin-response regulator, TRR8/9b. The accumulated data suggest that expression of Aux/IAA in the phloem modifies auxin sensitivity in a tissue-specific manner, thereby altering plant development. PMID:23986770

To further explore the biological role of the melon Aux/IAA transcript CmF-308 in the vascular tissue, a cassette containing the coding sequence of this gene under a phloem-specific promoter was introduced into tomato plants. The number of lateral roots was significantly higher in transgenic plants expressing CmF-308 under the AtSUC2 promoter than in controls. A similar effect on root development was obtained after transient expression of CmF-308 in source leaves of N. benthamiana plants. An auxin-response assay showed that CmF-308-transgenic roots are more sensitive to auxin than control roots. In addition to the altered root development, phloem-specific expression of CmF-308 resulted in shorter plants, a higher number of lateral shoots and delayed flowering, a phenotype resembling reduced apical dominance. In contrast to the root response, cotyledons of the transgenic plants were less sensitive to auxin than control cotyledons. The reduced auxin sensitivity in the shoot tissue was confirmed by lower relative expression of several Aux/IAA genes in leaves and an increase in the relative expression of a cytokinin-response regulator, TRR8/9b. The accumulated data suggest that expression of Aux/IAA in the phloem modifies auxin sensitivity in a tissue-specific manner, thereby altering plant development.

Alkoxy-auxins are selective inhibitors of auxin transport mediated by PIN, ABCB, and AUX1 transporters.  

PubMed

Polar auxin movement is a primary regulator of programmed and plastic plant development. Auxin transport is highly regulated at the cellular level and is mediated by coordinated transport activity of plasma membrane-localized PIN, ABCB, and AUX1/LAX transporters. The activity of these transporters has been extensively analyzed using a combination of pharmacological inhibitors, synthetic auxins, and knock-out mutants in Arabidopsis. However, efforts to analyze auxin-dependent growth in other species that are less tractable to genetic manipulation require more selective inhibitors than are currently available. In this report, we characterize the inhibitory activity of 5-alkoxy derivatives of indole 3-acetic acid and 7-alkoxy derivatives of naphthalene 1-acetic acid, finding that the hexyloxy and benzyloxy derivatives act as potent inhibitors of auxin action in plants. These alkoxy-auxin analogs inhibit polar auxin transport and tropic responses associated with asymmetric auxin distribution in Arabidopsis and maize. The alkoxy-auxin analogs inhibit auxin transport mediated by AUX1, PIN, and ABCB proteins expressed in yeast. However, these analogs did not inhibit or activate SCF(TIR1) auxin signaling and had no effect on the subcellular trafficking of PIN proteins. Together these results indicate that alkoxy-auxins are inactive auxin analogs for auxin signaling, but are recognized by PIN, ABCB, and AUX1 auxin transport proteins. Alkoxy-auxins are powerful new tools for analyses of auxin-dependent development. PMID:21084292

Depositional facies and hydrocarbon reservoir compartmentalization of the Mississippian Aux Vases Formation at King Field, Jefferson County, Illinois  

SciTech Connect

King field has produced over 4 million bbl of oil from the Mississippian Aux Vases Formation along a north-south-trending anticlinal structure 3 mi long and 1.5 mi wide. The porous and permeable quartz sandstone, which comprises the principal hydrocarbon reservoir, can grade laterally into nonporous calcareous sandstone, siltstone, shale, or limestone within one well location (660 ft). The Aux Vases Formation at King field was deposited in an intertidal to subtidal, mixed siliciclastic-carbonate environment, and the resulting mosaic of depositional facies significantly affects reservoirs continuity. Impermeable to only slightly permeable siltstones, shales, and limestones of the various offshore facies, and shales and siltstones of the tidal-flat facies separate the producing sandstones of a tidal channel-offshore bar facies into distinct reservoir compartments. This reservoir heterogeneity results in an oil-water contact at various depths across the field. Lateral compartmentalization of the reservoir has allowed large sections of the Aux Vases reservoir to remain unswept by waterflooding. Volumetric analyses suggest that untapped reservoir compartments may contain an additional 1-2 million bbl of oil recoverable by primary and waterflood methods.

Mesures en temps réel par diffusion de neutrons aux petits angles (DNPA) avec un appareil à ``flux stoppé'' (stopped-flow)  

NASA Astrophysics Data System (ADS)

La nouvelle génération de diffractomètres à haut flux pour la diffusion de neutrons aux petits angles, comme D22 à l'ILL, ouvre de nouvelles perspectives avec les expériences “temps réel” et les “cinétiques rapides”. “Temps réel” signifie un film de l'échantillon après une perturbation, par exemple un saut en température, une variation de pH, une dilution, un mélange ou encore l'application d'un champ magnétique. Par “rapide” on entend des temps d'acquisition courts, de l'ordre de quelques centaines de millisecondes pour suivre les toutes premières étapes de formation et d'organisation de l'échantillon. La connaissance d'éventuelles phases intermédiaires peut être cruciale pour comprendre les propriétés de l'échantillon dans son état d'équilibre. Pour ces expériences, un appareil à flux stoppé (Bio-Logic^TM) a été spécialement adapté pour la DNPA. Il permet de mélanger rapidement deux à trois solutions en contrôlant précisement les volumes et les temps de mélanges puis de démarrer l'observation en connaissant le délai après le début de la réaction. Cette nouvelle technique a été utilisée pour suivre la croissance de vésicules formées après dilution de micelles d'AOT par une solution saline. Le moteur de la croissance est l'écrantage des répulsions électrostatiques entre les têtes polaires tensioactives, ce qui favorise la formation d'une bicouche localement plane.

Coring Performance to Characterise the Geology in the ``Cran aux Iguanodons'' of Bernissart (Belgium)  

NASA Astrophysics Data System (ADS)

The Cran aux iguanodons of Bernissart is a sinkhole (or chimney caving) with a valuable paleontological deposit due to the exceptional quantity and diversity of fossils found during the excavation conducted from 1878 to 1881. In fact, bones have been discovered in a clayey geological formation when digging à mine gallery at the -322 m level. A subsequent extraction gave an overall production of 29 iguanodons skeletons. Referring to the available data at the Natural Sciences Museum of Brussels where the found skeletons are exhibited, one does not know the degree of depletion of the deposit after the extraction. A feasibility study (Tshibangu and Dagrain 1998) showed then the need to drill 4 exploration wells of 400 m depth with different objectives: to evaluate the chance of finding more fossils, understanding how and when the geological formations moved down, and testing a seismic geophysical technique for ground imaging. The typical geological formations concerned are: chalk, limestone, conglomerate, clays, and layers of silex nodules. In October 2002 the workings started with a completely cored well (the Number 3) using the PQ wireline technique. During operations, different parameters have been recorded: rate of penetration, core recovery and a brief core description. Some problems have been encountered when crossing silex stones contained in a clayey matrix; and this paper gives some interpretations in terms of the relationship between the lithology and the drilling performances.

Ectopic Overexpression of an AUXIN/INDOLE-3-ACETIC ACID (Aux/IAA) Gene OsIAA4 in Rice Induces Morphological Changes and Reduces Responsiveness to Auxin  

PubMed Central

Auxin has pleiotropic effects on plant growth and development. AUXIN/INDOLE-3-ACETIC ACID (Aux/IAA) proteins are short-lived transcriptional regulators that mediate auxin responses through interaction with an auxin receptor, the F-box protein transport inhibitor response 1 (TIR1). Most functions of Aux/IAA proteins have been identified in Arabidopsis by studying the gain-of-function mutants in domain II. In this study, we isolated and identified an Aux/IAA protein gene from rice, OsIAA4, whose protein contains a dominant mutation-type domain II. OsIAA4 has very low expression in the entire life cycle of rice. OsIAA4-overexpressing rice plants show dwarfism, increased tiller angles, reduced gravity response, and are less sensitive to synthetic auxin 2,4-dichlorophenoxyacetic acid (2,4-D).

Applications  

NASA Astrophysics Data System (ADS)

Economic incentives have spurred numerous applications of genetically engineered organisms in manufacture of pharmaceuticals and industrial chemicals. These successes, involving a variety of methods of genetic manipulation, have dispelled early fears that genetic engineering could not be handled safely, even in the laboratory. Consequently, the potential for applications in the wider environment without physical containment is being considered for agriculture, mining, pollution control, and pest control. These proposed applications range from modest extensions of current plant breeding techniques for new disease-resistant species to radical combinations of organisms (for example, nitrogen-fixing corn plants). These applications raise concerns about potential ecological impacts (see chapter 5), largely because of adverse experiences with both deliberate and inadvertent introductions of nonindigenous species.

Modèle multi-échelle du transport de fluide dans un milieu poreux chargé avec échanges cationiques : application aux tissus osseux  

NASA Astrophysics Data System (ADS)

To better understand the bone diseases, many models of porous cortical bone have been developed to simulate its in vivo behaviour. Thus we proposed multiscale models including multiphysical phenomena governing the hydraulic response of bone. However, all these models neglected the possible ionic exchanges at the cellular level. Since such chemical reactions directly change the physico-chemical properties of the tissue, the interstitial flow is also modified. The aim of this study is so to include these ionic exchanges in the bone fluid transport description by deriving their consequences at the macroscale. To cite this article: J. Kaiser et al., C. R.

Residus de 2-formes differentielles sur les surfaces algebriques et applications aux codes correcteurs d'erreurs  

NASA Astrophysics Data System (ADS)

The theory of algebraic-geometric codes has been developed in the beginning of the 80's after a paper of V.D. Goppa. Given a smooth projective algebraic curve X over a finite field, there are two different constructions of error-correcting codes. The first one, called "functional", uses some rational functions on X and the second one, called "differential", involves some rational 1-forms on this curve. Hundreds of papers are devoted to the study of such codes. In addition, a generalization of the functional construction for algebraic varieties of arbitrary dimension is given by Y. Manin in an article of 1984. A few papers about such codes has been published, but nothing has been done concerning a generalization of the differential construction to the higher-dimensional case. In this thesis, we propose a differential construction of codes on algebraic surfaces. Afterwards, we study the properties of these codes and particularly their relations with functional codes. A pretty surprising fact is that a main difference with the case of curves appears. Indeed, if in the case of curves, a differential code is always the orthogonal of a functional one, this assertion generally fails for surfaces. Last observation motivates the study of codes which are the orthogonal of some functional code on a surface. Therefore, we prove that, under some condition on the surface, these codes can be realized as sums of differential codes. Moreover, we show that some answers to some open problems "a la Bertini" could give very interesting informations on the parameters of these codes.

Diversification and Expression of the PIN, AUX/LAX, and ABCB Families of Putative Auxin Transporters in Populus  

PubMed Central

Intercellular transport of the plant hormone auxin is mediated by three families of membrane-bound protein carriers, with the PIN and ABCB families coding primarily for efflux proteins and the AUX/LAX family coding for influx proteins. In the last decade our understanding of gene and protein function for these transporters in Arabidopsis has expanded rapidly but very little is known about their role in woody plant development. Here we present a comprehensive account of all three families in the model woody species Populus, including chromosome distribution, protein structure, quantitative gene expression, and evolutionary relationships. The PIN and AUX/LAX gene families in Populus comprise 16 and 8 members respectively and show evidence for the retention of paralogs following a relatively recent whole genome duplication. There is also differential expression across tissues within many gene pairs. The ABCB family is previously undescribed in Populus and includes 20 members, showing a much deeper evolutionary history, including both tandem and whole genome duplication as well as probable gene loss. A striking number of these transporters are expressed in developing Populus stems and we suggest that evolutionary and structural relationships with known auxin transporters in Arabidopsis can point toward candidate genes for further study in Populus. This is especially important for the ABCBs, which is a large family and includes members in Arabidopsis that are able to transport other substrates in addition to auxin. Protein modeling, sequence alignment and expression data all point to ABCB1.1 as a likely auxin transport protein in Populus. Given that basipetal auxin flow through the cambial zone shapes the development of woody stems, it is important that we identify the full complement of genes involved in this process. This work should lay the foundation for studies targeting specific proteins for functional characterization and in situ localization.

Phenotypes associated with down-regulation of Sl-IAA27 support functional diversity among Aux/IAA family members in tomato.  

PubMed

The phytohormone auxin is known to regulate several aspects of plant development, and Aux/IAA transcription factors play a pivotal role in auxin signaling. To extend our understanding of the multiple functions of Aux/IAAs further, the present study describes the functional characterization of Sl-IAA27, a member of the tomato Aux/IAA gene family. Sl-IAA27 displays a distinct behavior compared with most Aux/IAA genes regarding the regulation of its expression by auxin, and the Sl-IAA27-encoded protein harbors a unique motif of unknown function also present in Sl-IAA9 and remarkably conserved in monocot and dicot species. Tomato transgenic plants underexpressing the Sl-IAA27 gene revealed multiple phenotypes related to vegetative and reproductive growth. Silencing of Sl-IAA27 results in higher auxin sensitivity, altered root development and reduced Chl content in leaves. Both ovule and pollen display a dramatic loss of fertility in Sl-IAA27 down-regulated lines, and the internal anatomy of the flower and the fruit are modified, with an enlarged placenta in smaller fruits. In line with the reduced Chl content in Sl-IAA27 RNA interference (RNAi) leaves, genes involved in Chl synthesis display lower expression at the level of transcript accumulation. Even though Sl-IAA27 is closely related to Sl-IAA9 in terms of sequence homology and the encoded proteins share common structural features, the data indicate that the two genes regulate tomato fruit initiation and development in a distinct manner.

Observation of linear to planar structural transition in sulfur-doped gold clusters: Au(x)S- (x = 2-5).  

PubMed

We report a joint experimental and theoretical study on the structures of a series of gold clusters doped with a sulfur atom, Au(x)S(-) (x = 2-5). Well-resolved photoelectron spectra are obtained and compared with theoretical results calculated using several density functional methods to elucidate the structures and bonding of Au(x)S(-) (x = 2-5). Au2S(-) is found to have an asymmetric linear global minimum structure with C(?v) symmetry, while the most stable structure of neutral Au2S is bent with C(2v) symmetry, reminiscent of H2S. Au3S(-) is found to have an asymmetric bent structure with an Au-S-Au-Au connectivity. Two isomers are observed experimentally to co-exist for Au4S(-): a symmetric bent 1D structure (C(2v)) and a 2D planar low-lying isomer (C(s)). The global minimum of Au5S(-) is found to be a highly stable planar triangular structure (C(2v)). Thus, a 1D-to-2D structural transition is observed in the Au(x)S(-) clusters as a function of x at x = 4. Molecular orbital analyses are carried out to obtain insight into the nature of the chemical bonding in the S-doped gold clusters. Strong covalent bonding between S and Au is found to be responsible for the 1D structures of Au(x)S(-) (x = 2-4), whereas delocalized Au-Au interactions favor the 2D planar structure for the larger Au5S(-) cluster.

Environmental and auxin regulation of wood formation involves members of the Aux/IAA gene family in hybrid aspen.  

PubMed

Indole acetic acid (IAA/auxin) profoundly affects wood formation but the molecular mechanism of auxin action in this process remains poorly understood. We have cloned cDNAs for eight members of the Aux/IAA gene family from hybrid aspen (Populus tremula L. x Populus tremuloides Michx.) that encode potential mediators of the auxin signal transduction pathway. These genes designated as PttIAA1-PttIAA8 are auxin inducible but differ in their requirement of de novo protein synthesis for auxin induction. The auxin induction of the PttIAA genes is also developmentally controlled as evidenced by the loss of their auxin inducibility during leaf maturation. The PttIAA genes are differentially expressed in the cell types of a developmental gradient comprising the wood-forming tissues. Interestingly, the expression of the PttIAA genes is downregulated during transition of the active cambium into dormancy, a process in which meristematic cells of the cambium lose their sensitivity to auxin. Auxin-regulated developmental reprogramming of wood formation during the induction of tension wood is accompanied by changes in the expression of PttIAA genes. The distinct tissue-specific expression patterns of the auxin inducible PttIAA genes in the cambial region together with the change in expression during dormancy transition and tension wood formation suggest a role for these genes in mediating cambial responses to auxin and xylem development.

Two hundred twenty-five yeasts, yeast-like fungi, and algae, comprising 28 species and including 30 isolates of Cryptococcus neoformans, an important pathogen not tested in appreciable numbers in other comparisons, were tested by both methods. On initial testing, 196 (87.1%) and 215 (95.6%) isolates were correctly identified by the RapID and API systems, respectively. Upon repeat testing, the number of correctly identified isolates increased to 220 (97.8%) for the RapID system and 223 (99.1%) for the API system. Reducing the turbidity of the test inoculum to that of a no. 3 McFarland turbidity standard, which is below that recommended by the manufacturer, resulted in the correct identification of most of the isolates initially misidentified by the RapID system, including 10 of 30 C. neoformans isolates. Concordance between the RapID and API results after repeat testing was 97.3%.

Developpement d'une plateforme de calcul d'equilibres chimiques complexes et adaptation aux problemes electrochimiques et d'equilibres contraints  

NASA Astrophysics Data System (ADS)

Avec l'arrivée de l'environnement comme enjeu mondial, le secteur de l'efficacité énergétique prend une place de plus en plus importante pour les entreprises autant au niveau économique que pour l'image de la compagnie. Par le fait même, le domaine des technologies de l'énergie est un créneau de recherche dont les projets en cours se multiplient. D'ailleurs, un des problèmes qui peut survenir fréquemment dans certaines entreprises est d'aller mesurer la composition des matériaux dans des conditions difficiles d'accès. C'est le cas par exemple de l'électrolyse de l'aluminium qui se réalise à des températures très élevées. Pour pallier à ce problème, il faut créer et valider des modèles mathématiques qui vont calculer la composition et les propriétés à l'équilibre du système chimique. Ainsi, l'objectif global du projet de recherche est de développer un outil de calcul d'équilibres chimiques complexes (plusieurs réactions et plusieurs phases) et l'adapter aux problèmes électrochimiques et d'équilibres contraints. Plus spécifiquement, la plateforme de calcul doit tenir compte de la variation de température due à un gain ou une perte en énergie du système. Elle doit aussi considérer la limitation de l'équilibre due à un taux de réaction et enfin, résoudre les problèmes d'équilibres électrochimiques. Pour y parvenir, les propriétés thermodynamiques telles que l'énergie libre de Gibbs, la fugacité et l'activité sont tout d'abord étudiées pour mieux comprendre les interactions moléculaires qui régissent les équilibres chimiques. Ensuite, un bilan énergétique est inséré à la plateforme de calcul, ce qui permet de calculer la température à laquelle le système est le plus stable en fonction d'une température initiale et d'une quantité d'énergie échangée. Puis, une contrainte cinétique est ajoutée au système afin de calculer les équilibres pseudo-stationnaires en évolution dans le temps. De plus, la contrainte d'un champ de potentiel électrique est considérée pour l'évaluation des équilibres électrochimiques par des techniques classiques de résolution et fera l'objet de travaux futurs via une technique d'optimisation. Enfin, les résultats obtenus sont comparés avec ceux présents dans la littérature scientifique pour valider le modèle. À terme, le modèle développé devient tin bon moyen de prédire des résultats en éliminant beaucoup de coût en recherche et développement. Les résultats ainsi obtenus sont applicables dans une grande variété de domaines tels que la chimie et l'électrochimie industrielle ainsi que la métallurgie et les matériaux. Ces applications permettraient de réduire la production de gaz à effet de serre en optimisant les procédés et en ayant une meilleure efficacité énergétique.

Distinguishing possible mechanisms for auxin-mediated developmental control in Arabidopsis: models with two Aux/IAA and ARF proteins, and two target gene-sets.  

PubMed

New models of gene transcriptional responses to auxin signalling in Arabidopsis are presented. This work extends a previous model of auxin signalling to include networks of gene-sets which may control developmental responses along auxin gradients. Key elements of this new study include models of signalling pathways and networks involving two Aux-IAA proteins (IAAs), auxin response factors (ARFs) and gene targets. Hypotheses for the gene network topologies which may be involved in developmental responses have been tested against experimental observations for root hair growth in particular. In studying these models, we provide a framework for the analysis of auxin signalling with multiple IAAs and ARFs, and discuss the implications of bistability in such systems. PMID:22067512

Microsoft Academic Search

In the first part of this paper, the authors present shortly the main tools used to predict airflow inside buildings. This description of the available tools allows to define the context in which they frame their works, the theoretical approach being unusual. The article deals with the exploitation of the so-called behavioural models, for the velocity coefficients calculation inside buildings.

Caracterisation mecanique dynamique de materiaux poro-visco-elastiques  

NASA Astrophysics Data System (ADS)

Poro-viscoelastic materials are well modelled with Biot-Allard equations. This model needs a number of geometrical parameters in order to describe the macroscopic geometry of the material and elastic parameters in order to describe the elastic properties of the material skeleton. Several characterisation methods of viscoelastic parameters of porous materials are studied in this thesis. Firstly, quasistatic and resonant characterization methods are described and analyzed. Secondly, a new inverse dynamic characterization of the same modulus is developed. The latter involves a two layers metal-porous beam, which is excited at the center. The input mobility is measured. The set-up is simplified compared to previous methods. The parameters are obtained via an inversion procedure based on the minimisation of the cost function comparing the measured and calculated frequency response functions (FRF). The calculation is done with a general laminate model. A parametric study identifies the optimal beam dimensions for maximum sensitivity of the inversion model. The advantage of using a code which is not taking into account fluid-structure interactions is the low computation time. For most materials, the effect of this interaction on the elastic properties is negligible. Several materials are tested to demonstrate the performance of the method compared to the classical quasi-static approaches, and set its limitations and range of validity. Finally, conclusions about their utilisation are given. Keywords. Elastic parameters, porous materials, anisotropy, vibration.

Cartographie de l'elevation de l'interface eau douce-eau salee aux iles-de-la-madeleine par la methode electromagnetique transitoire (TEM)  

NASA Astrophysics Data System (ADS)

This research project is dedicated to mapping the elevation of the freshwater-saltwater interface in Magdalen Islands using the transient electromagnetic method (TEM) in order to monitor time-varying quality of groundwater tables. Seventy-three TEM soundings were conducted between May 2010 and June 2011 close to Well regions in Fatima, Étang-du-Nord, Havre-Aux-Maisons, Grande-Entrée and Grosse-Île. TEM soundings were carried out with loops of 50 m x 50 m and 60 m x 40 m x 2 turns except some surveys of 100 m x 100 m. To control water quality and help constrain the interpretation of TEM soundings, conductivity logs were made in four previous exploration wells and fifteen wells drilled in 2009. Results show that saline water is associated with a low resistivity level between 2 and 4 ?.m and its elevation ranges from -40 m at Grand-Entrée and more than -250 m at Havre-Aubert. In Étang-du-Nord east, Fatima east and Grande-Entrée, saline water is shallow near shore and plunges inward as expected by the Ghyben Herzberg relation. These three areas have been identified to achieve the time-lapse monitoring of groundwater because of the risk associated with the proximity of wells in operation and the low elevation of saline water. Fatima center area close to FAT03 and FAT07 soundings and Havre-Aux-Maisons showed inconsistent results with the hydrogeological model, further work is recommended to verify the origin of the conductive areas highlighted. However, the results of the interpretation of areas at Havre-Aubert and Grosse-Île did not show a risk of contamination due to the depth of saline water. Modeling of the transition zone between the freshwater aquifer and the saline groundwater has demonstrated that it was difficult to solve it for thicknesses below 10 m and 30 m to depths of 40 and 130 m respectively. If the resistivity of the transition zone is known, the resolution is improved (5 and 10 m respectively). TEM soundings showed negative responses at late time associated with induced polarization (IP) effects. The inversion results of TEM soundings affected by this effect have shown that this dispersion most likely originates from near-surface layers. Chargeabilities ranging from 0.8 to 0.9 were obtained on the TEM soundings processed. The origin of this chargeability is currently unknown but could be related to the presence of fine material (clay). IP effect has not prevented determination of the saline water to a maximum depth of 250 m. The laboratory tests on core samples were unfortunately not able to determine the relationship between resistivity and water resistivity of saturated red sandstone. Immersion of cores in deionized water failed to eliminate the salt present in it. For time-varying monitoring of groundwater, we recommend performing drilling through the interface between freshwater and saltwater on selected areas, to conduct conductivity logs to fully characterize the level of this interface, to install multiparameter probes (conductivity, temperature, pressure) in monitoring wells located at different levels and to locate sites of TEM soundings in the vicinity that will be used to monitor the groundwater.

Les recommandations de prise en charge des complications m?taboliques associ?es aux antipsychotiques de deuxi?me g?n?ration chez les enfants et les adolescents  

PubMed Central

HISTORIQUE : Les antipsychotiques de deuxième génération s’associent souvent à des complications métaboliques. Ces médicaments sont utilisés plus souvent pour le traitement des troubles de santé mentale chez les enfants, ce qui a requis l’élaboration de lignes directrices officielles sur la surveillance de leur innocuité et de leur efficacité. Des lignes directrices ont déjà été élaborées pour surveiller les complications métaboliques et neurologiques. Afin d’aider les praticiens qui effectuent ces interventions de surveillance, une série de recommandations thérapeutiques complémentaires a été élaborée pour les cas où l’on observe des mesures ou des résultats anormaux. OBJECTIF : Créer des recommandations probantes afin de contribuer à la prise en charge des complications métaboliques chez les enfants traités au moyen d’antipsychotiques de deuxième génération. MÉTHODOLOGIE : Les auteurs ont procédé à une analyse systématique des publications sur les complications métaboliques des antipsychotiques de deuxième génération chez les enfants. Les membres du groupe consensuel ont évalué l’information recueillie grâce à l’analyse bibliographique systématique et ont fait appel à un processus de groupe nominal pour parvenir à un consensus à l’égard de recommandations thérapeutiques. Dans la mesure du possible, ils se sont reportés aux lignes directrices existantes sur l’évaluation et le traitement des anomalies métaboliques chez les enfants. RÉSULTATS : Des recommandations probantes sont présentées pour contribuer à la prise en charge des complications métaboliques, y compris la prise de poids, l’augmentation du tour de taille, l’élévation des taux de prolactine, de cholestérol, de triglycérides et de glucose, les épreuves de fonction hépatique anormales et les études thyroïdiennes anormales. CONCLUSION : Il faut recourir à des mesures de surveillance convenables lorsqu’on prescrit des antipsychotiques de deuxième génération. Les présentes lignes directrices thérapeutiques orientent les cliniciens quant à la prise en charge clinique des complications métaboliques lorsqu’elles se produisent.

HISTORIQUE ET OBJECTIF : L’utilisation d’antipsychotiques augmente chez les enfants. Le présent article visait à orienter les cliniciens quant à la prise en charge clinique des effets secondaires extrapyramidaux des antipsychotiques de deuxième génération. MÉTHODOLOGIE : Les publications, les entrevues avec des informateurs clés et des échanges avec les membres d’un groupe de discussion et les partenaires ont permis de déterminer les principaux secteurs cliniques d’orientation et les préférences quant à la structure des présentes recommandations. Les membres responsables des lignes directrices ont reçu le projet de recommandations, ont évalué l’information recueillie grâce à une analyse bibliographique systématique et ont utilisé un processus de groupe nominal pour parvenir à un consensus quant aux recommandations thérapeutiques. Les lignes directrices contiennent une description des anomalies neurologiques souvent observées avec l’utilisation d’antipsychotiques ainsi que les recommandations sur le moyen d’examiner et de quantifier ces anomalies. Une démarche séquentielle sur la prise en charge des anomalies neurologiques est présentée. RÉSULTATS : On peut observer plusieurs types de symptômes extrapyramidaux attribuables à l’utilisation d’antipsychotiques chez les enfants, y compris la dystonie aiguë, l’akathisie, le parkinsonisme et la dyskinésie tardive, toutes induites par les neuroleptiques, de même que la dystonie tardive, l’akathisie tardive et les dyskinésies de sevrage. La forte majorité des données probantes sur le traitement des troubles du mouvement induits par les antipsychotiques proviennent de patients adultes atteints de schizophrénie. Étant donné le peu de données pédiatriques, les recommandations découlent de publications portant tant sur des adultes que sur des enfants. Compte tenu des limites de généralisation des données provenant de sujets adultes pour des enfants, il faudrait évaluer ces recommandations d’après les avis d’experts plutôt que d’après les données probantes. CONCLUSION : Les cliniciens doivent savoir que les antipsychotiques de deuxième génération ont le potentiel d’induire des effets secondaires neurologiques et devraient faire preuve d’une extrême vigilance lorsqu’ils en prescrivent.

Caracterisation electrique de materiaux en composite pour fuselages d'avions  

NASA Astrophysics Data System (ADS)

In the last decade or so, the rise of oil price is being felt all over the world. Oil being one of the primary sources of energy highly exploited, it plays a great role in the today's world economy, especially in the transport domain. To remain competitive, companies striving in this domain need therefore to modify their approach in the design phase of new or improved products. In the aerospace industry for example, weight reduction in aircraft structures have become a primordial aspect in the design phase of new models making them lighter and more efficient. In the framework of this project, the research is related to new weight-reduction of structural materials used in aircrafts. As of today, much research effort has been undertaken to find good substitutes to replace the materials presently used (aluminum). Several materials such as aluminum-lithium and carbon fibre composite bring great interest as substitutes. This last one presents superior mechanical properties over aluminum such as lightweight and rigidity; its electrical properties though remain still ambiguous. The objective of this project, proposed by Bombardier Core EMC, is to find a way to characterize the composite in a conventional way that would allow an extraction of its electrical properties (permittivity (epsilonr), conductivity (sigma), etc). In this Master thesis, the existing studies and characterization approaches for the composite material are presented and discussed. These approaches will help anticipate the electrical behaviour of the composite material under test. A comparison between known elements (ex: aluminum) and the composite material will also be tackled in order to gauge its conductivity level, particularly for low frequencies (? MHz), and up to high frequencies (? 12 GHz). Finally, some tests have been simulated with electromagnetic modelling software in order to reproduce and validate the experimental results. At the end of the thesis, a discussion/conclusion presenting the results and validating their integrity is given. The results enable us to do an estimation of the composite's conductivity and to observe its attenuation properties in function of the frequency. The tests were made with composite laminated panels without wire mesh. The wire mesh here is a copper matrix integrated at the exterior surface of the composite for added electromagnetic protection.

Synthesis, characterization and applications for gold-silver alloy and nanoporous gold nanowires  

NASA Astrophysics Data System (ADS)

Electrodeposition of gold-silver alloys from a solution containing potassium gold cyanide, potassium silver cyanide and sodium carbonate has been investigated. Cyclic voltammograms for deposition from Au(CN)2- + Ag(CN)2- + Na2CO 3 (pH 13) solution show characteristic deposition peaks for gold and silver with the separation of 550 mV. The composition of the deposited alloys is dependent on the deposition potential (or current) and solution chemistry. Compositionally modulated AuxAg1-x/Au yAg1-y multilayers and multisegment nanowires were deposited from a single solution containing KAu(CN)2 + KAg(CN) 2 +Na2CO3 (pH 13). Multisegment nanowires were prepared by sequential deposition at -0.7 V and -1.2 V from Au(CN) 2- + Ag(CN)2- solution into porous Al2O3 templates. The different segments deposited at -0.7 V and -1.2 V are clearly distinguished by scanning electron microscopy and optical microscopy under blue light illumination. A two-step process has been developed for the fabrication of a new class of nanoparticles: nanoporous nanowires. The fabrication process involves electrochemical deposition of a single-phase binary alloy into a nanoporous template, followed by subsequent etching of the less noble component. These nanoporous gold nanowires are characterized by diameters of 20 nm or larger, lengths up to tens of microns, and a porous structure with controlled pore dimensions. In contrast to conventional solid nanoparticles, nanoporous nanowires have a high surface area and well defined pore morphology. Furthermore, nanoporous segments can be incorporated into multisegment nanorods or nanowires. In this dissertation, it is demonstrated that nanoporous gold (NPG) nanowires and multisegment nanowires incorporating Au/NPG layers and Pt/NPG layers can be fabricated by dealloying [Au/Au xAg1-x]n or [Pt/AuxAg1-x ]n (0.18 < x < 0.32) alloy nanowires. Application for nanowires in gene therapy has been explored. It has shown that DNA can be attached to the surface of gold nanowires using amine-terminated thiols [NH2-(CH2)n-SH]. Preliminary experiments indicate that transfection can be achieved with functionalized nanowires. Multiple functionality can be introduced into individual nanowires by exploiting the ability of different ligands to bind to different materials.

Etude de la performance de piles a combustible microbiennes et l'effet des materiaux d'electrodes  

NASA Astrophysics Data System (ADS)

Recent climate change has brought a whole new dimension to the energy field since now we must change our primary source, fossil fuels. The microbial fuel cell (MFC) technology emerged as a result of recent efforts in the development of alternative sources of energy. This project aims to improve the performance maximization of such celsl. It is assumed that the microbial fuel cells' functioning is influenced by the operation conditions as well as the biofilm development and other limitations. It is also appropriate to suppose that the electrode materials also have consequences on either the microorganisms' activity or the electrochemical reaction reactivity. Thus, various operating conditions and configurations are tested to identify the specific effects of these changes on cell performance. Also, the development of the biofilm is extensively studied under various conditions to improve the electrons transfer between the active biofilm and the anode. These experiments and analyses permitted to identify various effects that can improve the microbial fuel cell performance. Thus, the influence of organic load (of glucose and acetate), pH and operating temperature of the fuel cell has been shown and optimal values were determined, leading to a significant increase in the anodic biofilm activity and a decrease of the methanogens activity, the latter reducing the coulombic efficiency by diverting a non-negligible substrate amount for their benefit. Hence, organic loading of 2 to 4 g L-1 day-1, pH between 6,25 and 6,5 as well as high cathode temperature (62 °C) but moderate anode temperature (30 °C) caused a maximum power generation increase to 19,2 W m -3. During the experiments with acetate as substrate, distance between electrodes and fuel cell volume have been reduced, leading to a power density of 92,4 W m-3. All these observations are the subject of the first article presented in this thesis. Since the microbial fuel cell power generation depends on the number of anode-reducing microorganisms populating the biofilm, this relationship was deepened in the second manuscript. This article, which intended to monitor the biofilm development, highlights the influence of external load changing rate during the active biofilm growth. Thus, when the external load is adjusted rapidly to approach the cell internal resistance, electrons exchange is enhanced as well as the proliferation of microorganisms responsible of these electrons generation. By promoting faster anode-reducing microorganisms growth, other species are somewhat disadvantaged and substrate consumption is primarily involved in the electricity production rather than any other unwanted products (eg.: methane). This article also demonstrates the influence of the biofilm development level on the diffusion limitation of the anodic reaction, a limitation that becomes more pronounced as the biofilm grows. The third article clarifies the diffusion limitation of the charge transfer at the anode. Therefore, the organic load variation of acetate in microbial fuel cells with carbon felt (3D) and carbon paper (2D) anodes as well as the electrolyte conductivity decrease has targeted protons diffusion out of the biofilm as the current generation limitation. In addition, a secondary electrochemical reaction has been identified at the anode, creating an electrode resistance increase and thereby a slight power output decrease. Finally, multiple electrochemical analyses helped to establish with certainty that the electron transfer mechanism carried out by anode-reducing microorganisms is by direct contact with the anode via microorganisms themselves or the conductive biofilm matrix, cytochromes being responsible for the electrons transport in both cases. The last manuscript deals with new cathode materials (carbon, Mn 2O3 and Fe2O3) evaluation in comparison to a platinum cathode. These materials were chosen for their potential to stimulate the proliferation of microorganisms capable of influencing cathode activity in order to obtain a biocathode; however, this phenomenon has not been veri

Recuperation d'energie issue des deformations de structures aeronautiques a l'aide de materiaux piezoelectriques  

NASA Astrophysics Data System (ADS)

Aerospace structural maintenance (fuselage, wings) is a major component of operational costs which requires aircraft to be grounded and some of its parts to be dismantled in order to proceed to inspection. In order to allow in situ monitoring, Structural Health Monitoring (SHM) has been proposed where sensors and actuators are integrated on the structure. To avoid extensive wiring of the nodes, wireless sensors and actuators are attractive but should be self powered to fully benefit from them. One idea is to convert the mechanical energy (vibrations) available all over an aircraft into electricity using piezoelectric materials. This work investigates the potential of strain-based energy harvesters (as opposed to inertial harvesters) to supply wireless nodes on typical aircraft structures. A simple model is used to describe typical dynamic behavior of aircraft components: a beam representing the whole wing subjected to aerodynamic loading and a plate representing a fuselage panel subjected to pressure fields (jet noise and turbulent boundary layer). Various configurations of piezoelectric materials are tested such as bulk PZT, PZT fiber composite and Polyvinylidene Fluoride (PVDF) in order to evaluate the influence of their characteristics (size, polarization, electrodes' shape, capacitance...) on the harvested power. The results show that for a typical aerospace excitation of the beam (10 Hz and 56 ?def), the energy produced is up to 40 mJ with bulk PZT for a 7 minutes loading time. From the literature, this appears sufficient for RF transmission (25 ?J). For other excitation sources (for instance jet noise), the energy produced is up to only 1 mJ with bulk PZT for a 25 minutes loading time. The drawback is that we should wait for several seconds in order to charge the harvester's battery. And, considering that many other components than the RF transceiver will require energy in the meantime, the time laps between two' measures could increase to several minutes. Therefore, strain-based energy harvester could be used for supplying wireless sensor nodes but they would not allow real time measurement. However this approach is a simple and convenient way to scavenge energy compared to other kinds of harvesters (inertial, solar...) since it amounts to bonding a piezoelectric material on a flexible surface. Some design advices are eventually proposed for this kind of harvesters. They could be used for designing a harvester able to produce desired power from a known excitation. Keywords: Power harvesting, piezoelectric, piezoelectric fiber composite, vibration energy, structural health monitoring.

ERIP application instructions  

SciTech Connect

This report provides background information and instructions to assist applicants in writing Energy-Related Inventions Program (ERIP) applications. Initial feedback fro usage for the new instructions shows that the best instructions would not be read and followed by all applicants. Applications from more than thirty applicants who have received the new instructions indicated that few had read the instructions. Based on this feedback, the instructions have been further revised to include a title page and table of contents. A warning was also added to advise applicants of the potential penalty of delayed review if these instructions are not followed. This revision was intended to address the possibility that some applicants did not see or bother to follow the instructions which followed the background information about ERIP. Included are two examples of ERIP applications which have been prepared for handout at workshops or mailing to applicants. Writing of example applications was time consuming and more difficult than expected for several reasons: (1) Full disclosures can be lengthy, very detailed, and technical. This contrasts with the desire to prepare examples which are comparatively short and easy for the non-technical person to read. (2) Disclosures contain confidential information which should not be published. (3) It is difficult to imagine that applicants will study examples when they do not bother to read the basic instructions.

Aerogel materials posses such a wide variety of exceptional properties that a striking number of applications have developed for them. Many of the commercial applications of aerogels such as catalysts, thermal insulation, windows, and particle detectors are still under development and new application as have been publicized since the ISA4 Conference in 1994: e.g.; supercapacitors, insulation for heat storage in automobiles, electrodes for capacitive deionization, etc. More applications are evolving as the scientific and engineering community becomes familiar with the unusual and exceptional physical properties of aerogels, there are also scientific and technical application, as well. This paper discusses a variety of applications under development at Lawrence Livermore National Laboratory for which several types of aerogels are formed in custom sizes and shapes. Particular discussions will focus on the uses of aerogels for physics experiments which rely on the exceptional, sometimes unique, properties of aerogels.

Impuretés et systèmes corrélés. Des chaînes aux cuprates supraconducteurs  

NASA Astrophysics Data System (ADS)

Impurities and correlated systems Discovery of high TC superconductors has opened the new field of strongly correlated fermions physics. In these compounds, mostly transition metal oxides, strong correlations between electrons affect sharply their electronic properties. In order to determine accurately these correlations and their possible link with superconductivity, we study the effect of local defects such as non magnetic impurities. In fact, in the more simple case of insulating spin chains and ladders, these impurities induce a staggered magnetism in their neighborhood which reveals the underlying electronic correlations. Similar effects are observed in high TC superconductors, using local probes such as nuclear magnetic resonance. These observations allow to get a better understanding of both normal and superconducting state of these oxides, both full of surprises. La découverte des supraconducteurs à haute température critique a ouvert la voie à une nouvelle physique, celle des fermions fortement corrélés. Dans ces systèmes, le plus souvent des oxydes de métaux de transition, les fortes corrélations entre électrons affectent profondément leurs propriétés électroniques et induisent de nouveaux états originaux : liquides de spins, supraconductivité, etc. Pour mesurer ces corrélations et ainsi déterminer leur lien éventuel avec la supraconductivité, nous proposons d'étudier l'effet de défauts ponctuels tels que des impuretés non magnétiques. En effet, dans le cas plus simple de chaînes ou d'échelles de spin isolantes, ces impuretés induisent dans leur voisinage immédiat un magnétisme alterné révélateur des corrélations électroniques. Des effets semblables sont observés dans les supraconducteurs à haute température critique, grâce à des sondes locales comme la résonance magnétique nucléaire. Ces observations permettent de mieux comprendre à la fois l'état normal et supraconducteur de ces oxydes, tous deux riches en surprises.

La contribution des astronomes aux mesures de précision.  

NASA Astrophysics Data System (ADS)

The system for astronomical constants includes the astronomical unit, the velocity of light and the light-time for the unit distance in the metric system. In France, at least from the 17th century, scientists had in mind to unify the units. But it is not before the time of the French Revolution that it was succeeded to adopt a unified system based on the metre. Measurements were made of an arc of meridian, from Dunkirk to Barcelona to determine the new unit as the fraction of 1 over 107 of a quarter of any part of the Earth from the north pole to the equator. On the occasion of the bicentenary of the nomenclature of the metric system (1795), the Paris Observatory has presented during more than six months in 1995, mostly for students, manuscripts, documents related to the subject, in its galeries on the first floor of the Perrault building. The exhibition ended with the 1960 and 1983 definitions of the meter to which the Paris Observatory has contributed. For astronomers it was recalled the reason for which the Angström had to be considered as not more usable, being only close to the fraction 1/1010 of the meter.

Network aware distributed applications  

SciTech Connect

Most distributed applications today manage to utilize only a small percentage of the needed and available network bandwidth. Often application developers are not aware of the potential bandwidth of the network, and therefore do not know what to expect. Even when application developers are aware of the specifications of the machines and network links, they have few resources that can help determine why the expected performance was not achieved. What is needed is a ubiquitous and easy-to-use service that provides reliable, accurate, secure, and timely estimates of dynamic network properties. This service will help advise applications on how to make use of the network's increasing bandwidth and capabilities for traffic shaping and engineering. When fully implemented, this service will make building currently unrealizable levels of network awareness into distributed applications a relatively mundane task. For example, a remote data visualization application could choose between sending a wireframe, a pre-rendered image, or a 3-D representation, based on forecasts of CPU availability and power, compression options, and available bandwidth. The same service will provide on-demand performance information so that applications can compare predicted with actual results, and allow detailed queries about the end-to-end path for application and network tuning and debugging.

OCT for industrial applications  

NASA Astrophysics Data System (ADS)

Optical coherence tomography (OCT), as an interferometric method, has been studied as a distance ranger. As a technology capable of producing high-resolution, depth-resolved images of biological tissue, OCT had been widely used for the application of ophthalmology and has been commercialized in the market today. Enlightened by the emerging research interest in biomedical domain, the applications of OCT in industrial inspection were rejuvenated by a few groups to explore its potential for characterizing new materials, imaging or inspecting industrial parts as a service solution[3]. Benefiting from novel photonics components and devices, the industrial application of the older concepts in OCT can be re-visited with respect to the unique performance and availability. Commercial OCT developers such as Michelson Diagnostics (MDL; Orpington, U.K.) and Thorlabs (Newton, NJ) are actively exploring the application of OCT to industrial applications and they have outlined meaningful path toward the metrology application in emerging industry[3]. In this chapter, we will introduce the fundamental concepts of OCT and discuss its current and potential industrial applications.

New applications for MOEMS  

NASA Astrophysics Data System (ADS)

In 2001, the sudden downturn of Telecom business changed the optical MEMS landscape. Some MEMS companies who were focusing only on telecom applications shut down (OMM as the most famous example) and many companies stopped their optical MEMS developments (Atmel, Memscap). However, some companies succeed to explore new applications outside the telecom area with their telecom technological platform. Today, there is a renewal of the MOEMS business and there are very interesting market opportunities for DMD. This article describes the new market trends for MOEMS and DMD applications. Several new applications are now appearing aside TV and projections systems that will widespread the use of DMDs. Maskless lithography, wavefront correction (adaptive optics) adaptive front light signal for cars, digital printing are applications currently in development where matrix of micro-mirrors could be used. Maskless lithography is still in a R&D status. It will be a low volume market but high R&D investment application that could benefit to other applications. Market acceptance may be an issue: the two main players ASML and Canon have internal projects under evaluation but it still have to prove that it is an attractive technology. Moreover, other MOEMS markets such are barcode readers, spectrometers, micro bolometers are analyzed and quantified.

Batteries for Vehicular Applications  

NASA Astrophysics Data System (ADS)

This paper will describe battery technology as it relates to use in vehicular applications, including hybrid-electric vehicles (HEV), electric vehicles (EV), and plug-in-hybrid-electric vehicles (PHEV). The present status of rechargeable batteries, the requirements for each application, and the scientific stumbling blocks that stop batteries from being commercialized for these applications will be discussed. Focus will be on the class of batteries referred to as lithium batteries and the various chemistries that are the most promising for these applications. While Li-ion is expected in HEVs in the very near future, use in PHEVs are expected to be more gradual and dependent on solving the life, safety, and cost challenges. Finally, batteries for EVs remain problematic because of the range and charging-time issues.

Application Interoperability with SAMP  

NASA Astrophysics Data System (ADS)

The Simple Applications Messaging Protocol (SAMP) is a Virtual Observatory (VO) specification that enables astronomy software tools to exchange control information and data, allowing desktop applications to work as an integrated suite of tools rather than requiring complex functionality to be (redundantly) built into tools individually. In addition, SAMP allows new workflows to be created for the science user that leverages the advantages of each tool (e.g. visualization of tables or images, analysis, etc.), greatly reducing the time needed to switch between applications and tasks. We present here a short introduction to the protocol itself, a survey of some toolkits for application authors who wish to introduce SAMP functionality into their tools, and some examples of real-world usage.

Automated Inadvertent Intruder Application  

SciTech Connect

The Environmental Analysis and Performance Modeling group of Savannah River National Laboratory (SRNL) conducts performance assessments of the Savannah River Site (SRS) low-level waste facilities to meet the requirements of DOE Order 435.1. These performance assessments, which result in limits on the amounts of radiological substances that can be placed in the waste disposal facilities, consider numerous potential exposure pathways that could occur in the future. One set of exposure scenarios, known as inadvertent intruder analysis, considers the impact on hypothetical individuals who are assumed to inadvertently intrude onto the waste disposal site. Inadvertent intruder analysis considers three distinct scenarios for exposure referred to as the agriculture scenario, the resident scenario, and the post-drilling scenario. Each of these scenarios has specific exposure pathways that contribute to the overall dose for the scenario. For the inadvertent intruder analysis, the calculation of dose for the exposure pathways is a relatively straightforward algebraic calculation that utilizes dose conversion factors. Prior to 2004, these calculations were performed using an Excel spreadsheet. However, design checks of the spreadsheet calculations revealed that errors could be introduced inadvertently when copying spreadsheet formulas cell by cell and finding these errors was tedious and time consuming. This weakness led to the specification of functional requirements to create a software application that would automate the calculations for inadvertent intruder analysis using a controlled source of input parameters. This software application, named the Automated Inadvertent Intruder Application, has undergone rigorous testing of the internal calculations and meets software QA requirements. The Automated Inadvertent Intruder Application was intended to replace the previous spreadsheet analyses with an automated application that was verified to produce the same calculations and results. The application was extended to calculate full decay chains for a given parent so that an intruder calculation could be performed without any input from transport calculations, i.e. the intruder analysis was decoupled from groundwater analysis. Once this full decay chain capability was in place, the application was extended to perform a transient calculation of the dose to an intruder over a specified time range, from which the maximum dose in time was determined. Use of the transient calculation to find the maximum dose in time was a significant step forward in automating and simplifying the inadvertent intruder analysis. In conclusion: an automated application has been developed to perform inadvertent intruder analysis for SRS low-level waste facilities. The application performs a transient analysis to find the maximum dose in time for each parent considered. Due to its ease of use and the standardization of input and methods, the Automated Inadvertent Intruder Application has been adopted as standard practice for inadvertent intruder analysis at SRS.

Realisation de guides d'onde plans faibles pertes en nitrure de silicium pour un biocapteur integre  

NASA Astrophysics Data System (ADS)

Le nitrure de silicium est un materiau tres utilise en microelectronique et en optique integree due a l'excellente homogeneite et reproductibilite de son epaisseur et de son indice de refraction. De plus, l'indice de refraction eleve du nitrure de silicium est particulierement interessant pour les applications en biophotonique. En effet, ces dernieres annees les biocapteurs a champ evanescent ont demontre une augmentation de la sensibilite avec l'utilisation de guides d'onde plans a haut indice de refraction. La sensibilite pourrait etre encore amelioree en integrant sur un meme substrat l'ensemble des composants passifs et actifs (Lab-on-a-chip) qui composent le biocapteur a champ evanescent. L'integration des differents composants optiques passe par la fabrication d'un guide d'onde plan dans le visible qui soit realise avec des procedes a basse temperature, faible epaisseur, faible perte et haut indice de refraction. Meme si les couches d'oxyde metallique (TiO2, Ta2O5 par exemple), generalement utilisees pour ce type d'application, permettent d'obtenir de bonnes proprietes optiques, elles ne permettent pas d'atteindre la qualite des couches en nitrure de silicium notamment en termes de rugosite de surface pour de faibles epaisseurs. Dans le cadre de ces travaux de doctorat, les parametres du guide d'onde sont optimises pour une application utilisant des fluorophores a points quantiques emettant a 650 nm et excites avec une source laser a 532 nm. Une epaisseur de 80 nm est determinee comme optimale pour l'excitation, la collection de la fluorescence et le couplage fibre-guide. Le developpement d'un guide d'onde capable d'atteindre cette epaisseur et conservant des bonnes proprietes optiques est necessaire. A notre connaissance aucun travail n'a ete realise pour optimiser les pertes dans le visible des guides de nitrure de silicium, en fonction des parametres du procede PECVD. Dans ce travail de these, des guides d'onde sont fabriques pour la premiere fois en utilisant le nitrure depose par LF-PECVD (basse frequence), et leurs performances sont comparees aux guides deposes par HF-PECVD (haute frequence). Nous demontrons, en variant le debit des precurseurs, que l'absorption et les pertes en propagation des couches de nitrure sont plus faibles lorsque les depots sont faits par la technique LF-PECVD par rapport a la technique HFPECVD. Cette difference s'explique probablement par le fait que le bombardement ionique, beaucoup plus important a basse frequence qu'a haute frequence, reduit la presence d'amas de silicium dans la couche, responsables de l'absorption dans le visible en plus de densifier les couches par enlevement de l'hydrogene qui s'incorpore durant la deposition PECVD. Nous demontrons egalement que pour la technique LF-PECVD, les proprietes optiques des couches sont ameliorees en utilisant une basse puissance pour la source r-f du plasma. En effet a haute puissance, le bombardement, tres energetique cree des defauts dans la couche et favorise la rupture des liaisons N-H plutot que des liaisons Si-H. Finalement des guides d'onde plans de nitrure de silicium, avec une epaisseur de 80 nm et un indice de refraction de 2, sont fabriques et caracterises. Des pertes de 0.1 dB/cm a 633 nm et 1.05 dB/cm a 532 nm sont obtenues et comparees avec les performances des autres materiaux.

Recent applications of THERMUS  

NASA Astrophysics Data System (ADS)

Some of the most recent applications of the statistical-thermal model package, THERMUS, are reviewed. These applications focus on fluctuation and correlation observables in an ideal particle and anti-particle gas in limited momentum space segments, as well as in a hadron resonance gas. In the case of the latter, a Monte Carlo event generator, utilising THERMUS functionality and assuming thermal production of hadrons, is discussed. The system under consideration is sampled grand canonically in the Boltzmann approximation. A re-weighting scheme is then introduced to account for conservation of charges (baryon number, strangeness, electric charge) and energy and momentum, effectively allowing for extrapolation of grand canonical results to the micro canonical limit. The approach utilised in this and other applications suggests improvements to existing THERMUS calculations.

The transportation industry has increased its demands for extruded, cast, and sheet aluminum products, while the building and construction industries have demonstrated increased interest in new aluminum applications. The unique combination of properties provided by aluminum and its alloys make aluminum one of the most versatile, economical, and attractive materials for a wide range of applications. The low density and high strength of some alloys permit design and construction of strong, lightweight structures that are especially beneficial for bridges, buildings, and vehicles of all kinds. Aluminum is easily cast by all foundry processes, and can be readily worked into any needed form. Furthermore, increasing production efficiencies are making aluminum more cost-competitive with other materials. This article focuses on aluminum applications in automobiles, bridges, and housing.

APTASENSORS FOR BIOSECURITY APPLICATIONS  

SciTech Connect

Nucleic acid aptamers have found steadily increased utility and application steadily over the last decade. In particular, aptamers have been touted as a valuable complement to and in some cases replacement for antibodies due to their structural and functional robustness as well as their ease in generation and synthesis. They are thus attractive for biosecurity applications, e.g. pathogen detection, and are especially well suited since their in vitro generation process does not require infection of any host systems. Herein we provide a brief overview of the aptamers generated against biopathogens over the last few years. In addition, a few recently described detection platforms using aptamers (aptasensors) and potentially suitable for biosecurity applications will be discussed.

RNAi mechanisms and applications  

PubMed Central

Within the past two decades we have become increasingly aware of the roles that RNAs play in regulation of gene expression. The RNA world was given a booster shot with the discovery of RNA interference (RNAi), a compendium of mechanisms involving small RNAs (less than 30 bases long) that regulate the expression of genes in a variety of eukaryotic organisms. Rapid progress in our understanding of RNAi-based mechanisms has led to applications of this powerful process in studies of gene function as well as in therapeutic applications for the treatment of disease. RNAi-based therapies involve two-dimensional drug designs using only identification of good Watson-Crick base pairing between the RNAi guide strand and the target, thereby resulting in rapid design and testing of RNAi triggers. To date there are several clinical trials using RNAi, and we should expect the list of new applications to grow at a phenomenal rate. This article summarizes our current knowledge about the mechanisms and applications of RNAi.

Medical applications of holography  

NASA Astrophysics Data System (ADS)

From the various capabilities of holography for image processing and measuring purposes, holographic interferometric techniques have found more extended application in biological and medical research. Due to their special properties the different methods of holographic interferometry are applied to characteristic fields of biomedical investigations where--similar to nondestructive testing--vibration and deformation analysis is of interest. Features of holographic interferometry, such as the possibility of noncontactive, three-dimensional investigations with a large field-of-depth, are used with advantage. The main applications can be found in basic research e.g., in audiology, dentistry, opthalmology, and experimental orthopedics. Because of the great number of investigations and the variety of medical domains in which these investigations were performed this survey is confined to some characteristic examples. As in all fields of optics and laser metrology, a review on biomedical applications of holography would be incomplete if military developments and utilization were not mentioned. As demonstrated by selected examples, the increasing interlacing of science with the military does not stop at domains that traditionally are regarded as exclusively oriented to human welfare--like biomedical research. The term 'Star Wars Medicine', which becomes an increasingly popular expression for laser applications (including holography) in medicine, characterizes the consequences of this development.

BLAST+: architecture and applications  

PubMed Central

Background Sequence similarity searching is a very important bioinformatics task. While Basic Local Alignment Search Tool (BLAST) outperforms exact methods through its use of heuristics, the speed of the current BLAST software is suboptimal for very long queries or database sequences. There are also some shortcomings in the user-interface of the current command-line applications. Results We describe features and improvements of rewritten BLAST software and introduce new command-line applications. Long query sequences are broken into chunks for processing, in some cases leading to dramatically shorter run times. For long database sequences, it is possible to retrieve only the relevant parts of the sequence, reducing CPU time and memory usage for searches of short queries against databases of contigs or chromosomes. The program can now retrieve masking information for database sequences from the BLAST databases. A new modular software library can now access subject sequence data from arbitrary data sources. We introduce several new features, including strategy files that allow a user to save and reuse their favorite set of options. The strategy files can be uploaded to and downloaded from the NCBI BLAST web site. Conclusion The new BLAST command-line applications, compared to the current BLAST tools, demonstrate substantial speed improvements for long queries as well as chromosome length database sequences. We have also improved the user interface of the command-line applications.

'Grid' computing has emerged as an important new field, distinguished from conventional distributed computing by its focus on large-scale resource sharing, innovative applications, and, in some cases, high-performance orientation. In this talk, Dr. Foster defines this new field. First, he reviews the 'Grid problem,' which he defines as flexible, secure, coordinated resource sharing among dynamic collections of individuals, institutions, and resources - what he refers to as virtual organizations. In such settings, we encounter unique authentication, resource access, resource discovery, and other challenges. It is this class of problem that is addressed by Grid technologies. He presents an extensible and open Grid architecture, in which protocols, services, application programming interfaces, and software development kits are categorized according to their roles in enabling resource sharing. He also reviews major Grid projects worldwide and describes how they are contributing to the realization of this architecture.

Cosmetic applications of sclerotherapy.  

PubMed

The aim of this study was to broaden practitioner perspectives regarding the scope, safety, and efficacy of sclerotherapy for cosmetically unattractive veins and other conditions involving a variety of anatomical sites. The author wrote a review of results obtained following cosmetic sclerotherapy for both veins and in other applications is presented. This study involves hundreds of patients treated in a private phlebology practice spanning 33 years along with a brief review of pertinent literature. Since treatment of dilated veins involving the dorsa of the hands and face are rarely discussed, and widely performed, their treatment will be emphasized. The largely historical usefulness of sclerotherapy for other applications is also reviewed. As with lower extremity veins there was a great deal of both regional and patient-to-patient variability in terms of sensitivity to sclerosants and response to treatment. However, sclerotherapy carried out for cosmetic purposes has routinely produced satisfactory results for various applications and in a multiplicity of locations. Potentially serious complications and treatment failures were rare in properly selected patients. Patient satisfaction with a few exceptions was uniformly high. The addition of cosmetic sclerotherapy to an established phlebology practice can be a rewarding and highly satisfactory application of this versatile technique. Both treatment site, lesion type and the cosmetic nature of this therapy affects every aspect of treatment; legal, ethical, and procedural. Experience suggests that each area and type of lesion treated exhibits predictable patterns of response and risks. Vein treatment outcomes varying with anatomical site may reflect: 1) evolutionarily adaptive processes which have produced veins specialized for specific environments; 2) differences in patterns of cytokine recruitment and apoptotic processes. It should also be noted that potential complications reflect area specific patterns of venous anastomoses, nerves, vital structures, and the complexities of arterial architecture. PMID:22370568

Radiation applications: An overview  

SciTech Connect

Radiation has been successfully utilized for medical, industrial, and research applications since Roentgen first discovered X rays in the late 19th century. Today, intense fields of electron, photon, and neutron radiation are used for defense applications, and industrial processing, and both radiation sources and focused beams of radiation are routinely used in medicine for therapy and imaging. These advances in radiation technology have been coupled with the development of high-power reactors and high-power accelerators as well as continued improvements in the dosimetry of the delivered radiation. Radiation also can be a problem that must be dealt with. Aside from the obvious need to shield people and critical apparatus from the harmful effects of ionizing radiation, there are cases where the system must be designed to operate successfully in a radiation field. Reactor components such as fuel, internals, and pressure vessels must operate in neutron fields; fusion systems must operate in intense high-energy neutron fields; microelectronics used in space must operate in electron, proton, and cosmic ray fields; and accelerator components must operate in proton, neutron, and photon fields. Frequently, these components cannot be tested directly in the radiation fields to which they will be subjected, so simulation of the radiation fields with reactors, accelerators, or radiation sources has been developed to cope with this problem. This paper focuses on current applications of radiation processing, radiation effects in electronics, and radiation imaging.

Panoramic lens applications revisited  

NASA Astrophysics Data System (ADS)

During the last few years, innovative optical design strategies to generate and control image mapping have been successful in producing high-resolution digital imagers and projectors. This new generation of panoramic lenses includes catadioptric panoramic lenses, panoramic annular lenses, visible/IR fisheye lenses, anamorphic wide-angle attachments, and visible/IR panomorph lenses. Given that a wide-angle lens images a large field of view on a limited number of pixels, a systematic pixel-to-angle mapping will help the efficient use of each pixel in the field of view. In this paper, we present several modern applications of these modern types of hemispheric lenses. Recently, surveillance and security applications have been proposed and published in Security and Defence symposium. However, modern hemispheric lens can be used in many other fields. A panoramic imaging sensor contributes most to the perception of the world. Panoramic lenses are now ready to be deployed in many optical solutions. Covered applications include, but are not limited to medical imaging (endoscope, rigiscope, fiberscope...), remote sensing (pipe inspection, crime scene investigation, archeology...), multimedia (hemispheric projector, panoramic image...). Modern panoramic technologies allow simple and efficient digital image processing and the use of standard image analysis features (motion estimation, segmentation, object tracking, pattern recognition) in the complete 360° hemispheric area.

Foam fractionation applications.  

PubMed

Biotechnological downstream processing faces several challenges, such as dilute product streams and contained target products which are sensitive to heat, oxidation, other chemicals, etc. State-of-the-art separation methods, e.g. chromatography, are not always the best option due to variable yield losses and high costs. Foam fractionation appears as a promising alternative unit operation in biotechnological downstream processing. From its applications in metal industry and on fish farms, it was developed further towards the recovery of phytonutrients, metabolites and proteins. However, no large scale applications of foam fractionation in biotechnological downstream processing exist yet. This is due to the complexity of various biotechnological media, which makes a universalized approach for systematic process design of protein separations difficult. Ongoing research in the fields of process engineering, surface chemistry and protein chemistry can help to close this gap. Although many different substances, such as detergents, have been separated or recovered using foam fractionation, this review focuses mainly on biotechnological applications, more specifically on protein separation.

Next generation EFB applications  

NASA Astrophysics Data System (ADS)

Today pilots have to obtain required information from a number of different sources like airport/SID/STAR/approach or enroute charts (respectively their electronic representations), printouts like the flight plan or a weather briefing, and updates via voice communications. The flight crew is required to mentally combine all this information. This situation will become even more difficult to cope with in the SESAR/NextGen world with dynamic changes of the trajectory (flight plan), and more frequent updates of weather, NOTAMs and other information requiring a higher degree of automation and better information presentation. To address these issues, lower the pilot's workload, and increase his situational awareness, a concept is presented where all required information is provided through one application. Depending on the phase of flight (taxi-in/taxi-out, departure, enroute, arrival, approach) the application will select the currently required information and provide a seamless representation for the crew. The challenge is to provide the right information at the right time to the crew (e.g. significant weather moving into the direction of the flight plan). The focus of this paper will be on the components of the new application related to ground operations. This includes an enhanced, AMM-like view with integrated taxi-routing support, graphical and textual display of chart notes (e.g. wingspan restrictions, taxiway closures etc.), and updates of such information by automatic inclusion of digital NOTAMs.

Commercial applications for COIL  

NASA Astrophysics Data System (ADS)

The chemical oxygen-iodine laser (COIL) is a high power, fiber deliverable tool, which can be used for a number of different industrial applications. COIL is of particular interest because of its short fiber deliverable wavelength, high scaleable continuous wave power, and excellent material interaction properties. In past research the University of Illinois at Urbana-Champaign identified and decommissioning and decontamination (DD) of nuclear facilities as a primary focus for COIL technology. DD will be a major challenge in the coming decades. The use of a robotically driven fiber delivered cutting/ablation tool in contaminated areas promises to lower risks to workers for the DD mission. Further, the high cutting speed of COIL will significantly reduce the time required to cut contaminated equipment, reducing costs. The high power of COIL will permit the dismantling of thick stacks of piping and equipment as well as reactor vessels. COIL is very promising for the removal of material from contaminated surfaces, perhaps to depths thicker than an inch. Laser cutting and ablation minimizes dust and fumes, which reduces the required number of high efficiency particulate accumulator filters, thus reducing costly waste disposal. Other potential industrial applications for COIL are shipbuilding, automotive manufacturing, heavy machinery manufacturing, tasks requiring underwater cutting or welding, and there appear to be very promising applications for high powers lasers in the oil industry.

New emerging MEMS applications  

NASA Astrophysics Data System (ADS)

This paper presents the trends for the years to come for the different MEMS markets. Consumer applications have really started to push the MEMS business in 2005. Many different devices are involved, like pressure sensors (altimeters), microphones, accelerometers, gyroscopes . . . One of the most significant consequences is that all the Top 50 semiconductor companies are now looking at these MEMS applications as possible growth areas. Another result of the growth of the MEMS market is the strong growth of the foundries and contract manufacturers. We have seen growth of more than 35% in 2005 compared to 2004 and we expect similar growth in the next 3 years. We will review the next MEMS applications which have currently a high growth: Si microphones, microdisplays (for RPTV, portable projectors or automotive HUDs), gyroscopes and micro-fuel cells. In the longer term, micro-source of energy could also become an important MEMS market. In term of milestones, the following points can be highlighted: -In 2005 market, the MEMS market is 5.1 B$ worldwide and very fragmented in terms of companies and products. -In 2010, it will be a 9.7 B$ market worldwide. MEMS foundries and contract manufacturers will account for at least 8 % of the world market with several being public companies. More than 50% of today's systems companies who have integrated fabs will be using external manufacturers. Several large integrated companies will have created independent MEMS spin-offs and IC manufacturers will be deeply involved in MEMS manufacturing. -In 2015, it will be an 18 B$ market worldwide with no longer systems manufacturers with internal fabs. And we forecast that 50% of the total market will be in the hands of semiconductor manufacturers.

Radar applications overview  

NASA Astrophysics Data System (ADS)

During the fifty years since its initial development as a means of providing early warning of airborne attacks against allied countries during World War II, radar systems have developed to the point of being highly mobile and versatile systems capable of supporting a wide variety of remote sensing applications. Instead of being tied to stationary land-based sites, radar systems have found their way into highly mobile land vehicles as well as into aircraft, missiles, and ships of all sizes. Of all these applications, however, the most exciting revolution has occurred in the airborne platform arena where advanced technology radars can be found in all shapes and sizes...ranging from the large AWACS and Joint STARS long range surveillance and targeting systems to small millimeter wave multi-spectral sensors on smart weapons that can detect and identify their targets through the use of highly sophisticated digital signal processing hardware and software. This paper presents an overview of these radar applications with the emphasis on modern airborne sensors that span the RF spectrum. It will identify and describe the factors that influence the parameters of low frequency and ultra wide band radars designed to penetrate ground and dense foliage environments and locate within them buried mines, enemy armor, and other concealed or camouflaged weapons of war. It will similarly examine the factors that lead to the development of airborne radar systems that support long range extended endurance airborne surveillance platforms designed to detect and precision-located both small high speed airborne threats as well as highly mobile time critical moving and stationary surface vehicles. The mission needs and associated radar design impacts will be contrasted with those of radar systems designed for high maneuverability rapid acquisition tactical strike warfare platforms, and shorter range cued air-to-surface weapons with integral smart radar sensors.

Photocathodes in accelerator applications  

SciTech Connect

Some electron accelerator applications require bursts of short pulses at high microscopic repetition rates and high peak brightness. A photocathode, illuminated by a mode-locked laser, is well suited to filling this need. The intrinsic brightness of a photoemitter beam is high; experiments are under way at Los Alamos to study the brightness of short bunches with high space charge after acceleration. A laser-illuminated Cs/sub 3/Sb photoemitter is located in the first rf cavity of an injector linac. Diagnostics include a pepper-pot emittance analyzer, a magnetic spectrometer, and a streak camera.

Factorizing monolithic applications  

SciTech Connect

The Blanca project is part of the US Department of Energy`s (DOE) Accelerated Strategic Computing Initiative (ASCI), which focuses on Science-Based Stockpile Stewardship through the large-scale simulation of multi-physics, multi-dimensional problems. Blanca is the only Los Alamos National Laboratory (LANL)-based ASCI project that is written entirely in C++. Tecolote, a new framework used in developing Blanca physics codes, provides an infrastructure for gluing together any number of components; this framework is then used to create applications that encompass a wide variety of physics models, numerical solution options, and underlying data storage schemes. The advantage of this approach is that only the essential components for the given model need be activated at runtime. Tecolote has been designed for code re-use and to isolate the computer science mechanics from the physics aspects as much as possible -- allowing physics model developers to write algorithms in a style quite similar to the underlying physics equations that govern the computational physics. This paper describes the advantages of component architectures and contrasts the Tecolote framework with Microsoft`s OLE and Apple`s OpenDoc. An actual factorization of a traditional monolithic application into its basic components is also described.

Corrosion in bioprocessing applications.  

PubMed

Corrosion in bioprocessing applications is described for a 25-year-old bioprocessing pilot plant facility. Various available stainless steel alloys differ greatly in properties owing to the impact of specific alloying elements and their concentrations. The alloy property evaluated was corrosion resistance as a function of composition under typical bioprocessing conditions such as sterilization, fermentation, and cleaning. Several non-uniform forms of corrosion relevant to bioprocessing applications (e.g., pitting, crevice corrosion, intergranular attack) were investigated for their typical causes and effects, as well as alloy susceptibility. Next, the corrosion resistance of various alloys to specific bioprocessing-relevant sources of corrosion (e.g., medium components, acids/bases used for pH adjustment, organic acid by-products) was evaluated, along with the impact of temperature on corrosion progression. Best practices to minimize corrosion included considerations for fabrication (e.g., welding, heat treatments) and operational (e.g., sterilization, media component selection, cleaning) approaches. Assessments and repair strategies for observed corrosion events were developed and implemented, resulting in improved vessel and overall facility longevity. PMID:18512080

Applications of Groundwater Helium  

USGS Publications Warehouse

Helium abundance and isotope variations have widespread application in groundwater-related studies. This stems from the inert nature of this noble gas and the fact that its two isotopes ? helium-3 and helium-4 ? have distinct origins and vary widely in different terrestrial reservoirs. These attributes allow He concentrations and 3He/4He isotope ratios to be used to recognize and quantify the influence of a number of potential contributors to the total He budget of a groundwater sample. These are atmospheric components, such as air-equilibrated and air-entrained He, as well as terrigenic components, including in situ (aquifer) He, deep crustal and/or mantle He and tritiogenic 3He. Each of these components can be exploited to reveal information on a number of topics, from groundwater chronology, through degassing of the Earth?s crust to the role of faults in the transfer of mantle-derived volatiles to the surface. In this review, we present a guide to how groundwater He is collected from aquifer systems and quantitatively measured in the laboratory. We then illustrate the approach of resolving the measured He characteristics into its component structures using assumptions of endmember compositions. This is followed by a discussion of the application of groundwater He to the types of topics mentioned above using case studies from aquifers in California and Australia. Finally, we present possible future research directions involving dissolved He in groundwater.

Environmental applications for biosurfactants.  

PubMed

Biosurfactants are surfactants that are produced extracellularly or as part of the cell membrane by bacteria, yeasts and fungi. Examples include Pseudomonas aeruginosa which produces rhamnolipids, Candida (formerly Torulopsis) bombicola, one of the few yeasts to produce biosurfactants, which produces high yields of sophorolipids from vegetable oils and sugars and Bacillus subtilis which produces a lipopeptide called surfactin. This review includes environmental applications of these biosurfactants for soil and water treatment. Biosurfactant applications in the environmental industries are promising due to their biodegradability, low toxicity and effectiveness in enhancing biodegradation and solubilization of low solubility compounds. However, more information is needed to be able to predict and model their behaviour. Full scale tests will be required. The role of biosurfactants in natural attenuation processes has not been determined. Very little information is available concerning the influence of soil components on the remediation process with biosurfactants. As most of the research until now has been performed with rhamnolipids, other biosurfactants need to be investigated as they may have more promising properties. PMID:15519450

Applications of geometric quantization  

SciTech Connect

Two applications of geometric quantization are described here. In the first, the classical system whose phase space is a two-sphere is quantized with an anti-holomorphic Kahler polarization. The result is an isolated quantum spin degree of freedom, with integral or half-integral total spin. A convenient formalism for handling geometric quantization with a Kahler polarization is exhibited. The second application is a discussion of several approaches to the quantization of classical systems with first class constraints. It is shown that there is a quantization procedure, called here the constrained polarization method, which is equivalent to quantizing (with a real polarization) the true classical degrees of freedom. This new method is often more convenient than directly quantizing the reduced phase space. In an example, it is shown that the time-honored procedure of imposing constraints as quantum operator equations can result in a mathematically non-viable quantum theory, if the chosen polarization is not compatible with the constraints. For this particular example, which is somewhat reminiscent of the canonical description of general relativity, there is a polarization compatible with constraints.

Microwave radiometry and applications  

NASA Astrophysics Data System (ADS)

The radiometry in general is a method of detecting the radiation of matter. All material bodies and substances radiate energy in the form of electromagnetic waves according to Planck s Law. The frequency spectrum of such thermal radiation is determined, beyond the properties of a blackbody, by the emissivity of surfaces and by the temperature of a particular body. Also, its reflectivity and dispersion take part. Investigating the intensity of radiation and its spectral distribution, one may determine the temperature and characterize the radiating body as well as the ambient medium, all independently of distance. With the above possibilities, the radiometry represents a base of scientific method called remote sensing. Utilizing various models, temperature of distant bodies and images of observed scenes can be determined from the spatial distribution of radiation. In this method, two parameters are of paramount importance: the temperature resolution, which flows out from the detected energy, and the spatial resolution (or, angular resolution), which depends upon antenna size with respect to wavelength. An instrument usable to conduct radiometric observations thus consists of two basic elements: a detector or radiometer, which determines the temperature resolution, and an antenna which determines the angular or spatial resolution. For example, a photographic camera consists of an objective lens (antenna) and of a sensitive element (a film or a CCD). In remote sensing, different lenses and reflectors and different sensors are employed, both adjusted to a particular spectrum region in which certain important features of observed bodies and scenes are present: frequently, UV and IR bands are used. The microwave radiometry utilizes various types of antennas and detectors and provides some advantages in observing various scenes: the temperature resolution is recently being given in milikelvins, while the range extends from zero to millions of Kelvins. Microwaves also offer a chance to penetrate surfaces of non-metallic objects down to some wavelengths, by which it is advantageous in certain applications over e.g. IR waves. An extreme example of capabilities of the microwave radiometry is found in radio astronomy, where it determines temperatures and spectral features of bodies so remote that their distance from us is measured in millions of light years. Other apparatus serve in remote observation of Earth s resources: soils, water regions and atmosphere. Similar systems also have found applications in medical studies of human body, e.g. in cancer and inflammation diagnostics. The paper presents a background of the radiometric method, comments to equipment design and outlines some of the applications.

Electrodes for microfluidic applications  

DOEpatents

An electrode device for high pressure applications. These electrodes, designed to withstand pressure of greater than 10,000 psi, are adapted for use in microfluidic devices that employ electrokinetic or electrophoretic flow. The electrode is composed, generally, of an outer electrically insulating tubular body having a porous ceramic frit material disposed in one end of the outer body. The pores of the porous ceramic material are filled with an ion conductive polymer resin. A conductive material situated on the upper surface of the porous ceramic frit material and, thus isolated from direct contact with the electrolyte, forms a gas diffusion electrode. A metal current collector, in contact with the gas diffusion electrode, provides connection to a voltage source.

Laser applications in neurosurgery  

NASA Astrophysics Data System (ADS)

The ``false start'' of the laser in neurosurgery should not be misconstrued as a denial of the inherent advantages of precision and gentleness in dealing with neural tissue. Rather, early investigators were frustrated by unrealistic expectations, cumbersome equipment, and a general ignorance of microtechnique. By the early 70s, microneurosurgery was well established, surgical laser equipment for free hand and microlinked application had been developed, and a more realistic view of the limitations of the laser had been established. Consequently, the late 70s really heralded the renaissance of the laser in neurosurgery. Since then, there has been an overwhelming acceptance of the tool in a variety of clinical situations, broadly categorized in five groups. 1)|Perhaps the most generally accepted area is in the removal of extra-axial tumors of the brain and spinal cord. These tumors, benign by histology but treacherous by location, do not present until a significant amount of neurological compensation has already occurred. The application of additional trauma to the neural tissue, whether by further tumor growth or surgical manipulation, frequently results in irreversible damage. Here, the ability of the laser to vaporize tissue, in a fairly hemostatic fashion, without mechanical or thermal damage to sensitive surrounding tissues, is essential. 2)|The ability to incise delicate neural tissue with minimal spread of thermal destruction to adjacent functioning tissue makes the laser the ideal instrument when tumors deep under the surface are encountered in the brain or spinal cord. Thus, the second group of applications is in the transgression of normal neural structures to arrive at deeper pathological tissue. 3)|The third area of benefit for the laser in neurosurgery has been in the performance of neuroablative procedures, calling for deliberate destruction of functioning neural tissue in a controlled fashion. Again, the precision and shape confinement of the destructive beam makes the laser superior to all conventional destructive instruments. 4)|The coagulative properties of certain chromophoric lasers has allowed a new attack on certain vascular tumors and malformations of the brain and spinal cord which had been operated only with trepidation or not at all. Early reports are sobering but encouraging. 5)|Finally, the use of the laser with tissue photosensitization, albeit it in its infancy, offers great promise. This is particularly true in the case of primary brain cancer, where the infiltration of tumorous tissue among normal pathways precludes the classical oncologic surgery practice of resection of a ``safe margin''. The ability to track and destroy these cells, without affecting adjacent cells, may be the greatest single contribution of the laser to neurosurgery in the future. The present applications of the laser are relatively crude by comparison with what is expected. Endoscopic laser surgery, both vascular and subarachnoid, will diminish morbidity and improve results. From the exotic treatment of aneurysms and arteriovenous malformations of the brain to the mundane care of herniated disks of the spine, it is anticipated that the laser will play an important role. The use of a laser, coupled with computerized imagining devices, will allow increasing precision in arrival to and treatment of deep seated lesions of the brain, brainstem, and spinal cord. The use of different wavelengths, perhaps in the X-ray and ultraviolet spectra, will allow increasing precision with decreasing invasion. Manipulation of wavelength, time, and treatment area will allow subcellular surgery, perhaps in the treatment of personality disorders and movement disorders as well as epilepsy. Tissue welding will allow heightened regenerative and recuperative powers to be exploited. The possibility of laser biostimulation must also be considered. In short, it appears that the future of the laser in neurosurgery is limited only by the imagination of the surgeons. Certainly, the opportunity to exploit new wavelengths offered by the FEL is the key to

ICE SLURRY APPLICATIONS.  

PubMed

The role of secondary refrigerants is expected to grow as the focus on the reduction of greenhouse gas emissions increases. The effectiveness of secondary refrigerants can be improved when phase changing media are introduced in place of single phase media. Operating at temperatures below the freezing point of water, ice slurry facilitates several efficiency improvements such as reductions in pumping energy consumption as well as lowering the required temperature difference in heat exchangers due to the beneficial thermo-physical properties of ice slurry. Research has shown that ice slurry can be engineered to have ideal ice particle characteristics so that it can be easily stored in tanks without agglomeration and then be extractable for pumping at very high ice fraction without plugging. In addition ice slurry can be used in many direct contact food and medical protective cooling applications. This paper provides an overview of the latest developments in ice slurry technology.

Applications in spinal imbalance.  

PubMed

The pelvis may be seen as a single vertebra, between the spine and the femurs. The anatomy of this pelvic vertebra has changed with the evolution of species, notably with the transition to bipedalism, with the consequent appearance of lumbar lordosis. The lumbosacral angle, almost non-existent in other mammals, is at its greatest in humans. Pelvic and spinal radiological parameters reflect the sagittal balance of the spine in bipedal humanity. Applications in the management of spinal imbalance are numerous. Arthrogenic or degenerative kyphosis is the stereotypic example of spinal aging. Postoperative flat back following spine surgery is hard to prevent. Scoliosis surgery in adults should now take greater account of the patient's individual sagittal balance, by analyzing the pelvic and spinal parameters. The extent of arthrodeses performed during adolescence to manage idiopathic scoliosis may also induce problems of balance in adulthood if these elements are not taken into account. PMID:20447889

Applications of effective Lagrangians  

SciTech Connect

This thesis contains some applications of effective field theories in particle physics. The impact of a fourth generation of quarks on neutral kaon mixing is considered, and the results are extended to the mixing and CP violating phenomenology of neutral bottom meson systems. A phenomenological Lagrangian is constructed to describe radiative vector meson decays. The measured decay rates are reproduced, and one prediction is made. It is shown that the large-N approximation in the standard model cannot explain the {Delta}I = {1/2} rule for kaon nonleptonic decays, even when short distance effects such as Penguins are included. Finally, the contribution of small instantons to the axion potential is calculated. The induced potential can be a large if the QCD coupling is non-decreasing at high energies, and if a suppression by light quark masses can be avoided using loops of scalars.

Nanodielectrics for Cryogenic Applications  

SciTech Connect

In this paper we report the recent advances in nanodielectrics that were developed and tested for cryogenic dielectric applications. The systems studied are composed of nanometer size particles. Particles were produced using either an ex-situ or in-situ technique. It is observed that there are clear differences in the structural properties of materials produced using these two approaches. Either no significant degradation or improvement in the electrical insulation properties were observed for ex-situ nano-particle samples processed with an ultrasonic processor and in-situ nano-particle samples. Nanodielectrics have the potential to be tailored with better thermal and mechanical properties without losing their electrical insulation characteristics.

Biostatistical applications in epidemiology.

Understanding the application of statistical methods is an essential component in the process of evaluating the medical literature. Statistical methods can differ when evaluating randomized controlled clinical trials (experimental design) compared with observational study designs such as cohort or case-control. A review of common statistical concepts includes variables, measures of central tendency, and measures of dispersion. Other methods include sensitivity, specificity, and predictive value. Observational study designs often include relative risk, odds ratios, relative risk reduction, attributable risk, number needed to treat, and forest plots. A critical component of drug literature evaluation is the understanding of the proper use of parametric and nonparametric statistical tests. Common parametric tests and their nonparametric equivalents are discussed. PMID:21182354

Turbulence management: Application aspects  

NASA Astrophysics Data System (ADS)

Turbulence management for the reduction of turbulent friction drag is an important topic. Numerous research programs in this field have demonstrated that valuable net drag reduction is obtainable by techniques which do not involve substantial, expensive modifications or redesign of existing aircraft. Hence, large projects aiming at short term introduction of turbulence management technology into airline service are presently under development. The various points that have to be investigated for this purpose are presented. Both design and operational aspects are considered, the first dealing with optimizing of turbulence management techniques at operating conditions, and the latter defining the technical problems involved by application of turbulence management to in-service aircraft. The cooperative activities of Airbus Industrie and its partners are cited as an example.

We have made extensive efforts to insure that the technology development of Modular Gravitational Reference Sensor (MGRS) will benefit broader range of space missions, not only MGRS itself. We will give several examples of applications of MGRS technologies. The radiation hardness of GaN UV LED implies a whole new family of semiconductor devices that will work in the harsh radiation environment for planetary exploratory missions. The grating angular sensor will facilitate small satellite cluster flights that require high precision attitude control. The optical shadow sensor will provide a simple and low cost reference for sub nanometer gravitation reference for gravity profiling. The center of mass measurement techniques have been generalized to cubic proof mass characterization.

Clinical application of ghrelin.  

PubMed

Ghrelin as a human natural hormone is involved in fundamental regulatory processes of eating and energy balance. Ghrelin signals the nutrient availability from the gastrointestinal tract to the central nervous system, up-regulates food intake and lowers energy expenditure mainly through hypothalamic mediators acting both centrally and peripherally including the gastrointestinal tract (motility, epithelium), promotes both neuro-endocrine and inflammatory signals to increase skeletal muscle growth and decrease protein breakdown, and increases lipolysis while body fat utilization is reduced. Ghrelin does more to exert its probably sentinel role around "human energy": it influences through mainly extra-hypothalamic actions the hedonic and incentive value of food, mood and anxiety, sleep-wake regulation, learning and memory, and neurogenesis. Recently numerous ghrelin gene-derived peptides were discovered, demonstrating the complexity within the ghrelin/ghrelin receptor axis. For clinical applications, not only the natural ghrelin and its slice variants, but also several modified or artificial molecules acting at ghrelin-associated receptors were and are developed. Current clinical applications are limited to clinical studies, focusing mainly on cachexia in chronic heart failure, COPD, cancer, endstage- renal-disease or cystic fibrosis, but also on frailty in elderly, gastrointestinal motility (e.g., gastroparesis, functional dyspepsia, postoperative ileus), after curative gastrectomy, anorexia nervosa, growth hormone deficient patients, alcohol craving, sleep-wake regulation (e.g. major depression), or sympathetic nervous activity in obesity. The results of completed, preliminary studies support the clinical potential of ghrelin, ghrelin gene-derived peptides, and artificial analogues, suggesting that larger clinical trials are demanded to move ghrelin towards an available and reimbursed pharmaceutical intervention.

Enabling network-aware applications  

SciTech Connect

Many high performance distributed applications use only a small fraction of their available bandwidth. A common cause of this problem is not a flaw in the application design, but rather improperly tuned network settings. Proper tuning techniques, such as setting the correct TCP buffers and using parallel streams, are well known in the networking community, but outside the networking community they are infrequently applied. In this paper, we describe a service that makes the task of network tuning trivial for application developers and users. Widespread use of this service should virtually eliminate a common stumbling block for high performance distributed applications.

Parylene for MEMS applications  

NASA Astrophysics Data System (ADS)

The goal of this thesis is to utilize Parylene, a room-temperature chemical-vapor-deposited (CVD) polymer, for MicroElectroMechanical Systems (MEMS) applications. The identified unique properties of Parylene are used to fabricate various micromachining devices such as thermopneumatic microvalve, in-channel microflow restrictor, and electret microphones. First, the properties of Parylene as a MEMS material are reviewed. The electrical, thermal, surface, and mechanical properties are first compared with that of other materials and further studied specifically for MEMS applications. The high dielectric strength (determined as 250V/mum) of Parylene makes it suitable for use as an electrical insulation material. However, its high resistivity causes un-desired charging effects first described in polymer-based electrostatic devices. The undesired high pull-in voltage, "bounce-back," and "snap-down" effects caused by dielectric charging are studied. Second, to make Parylene as a surface-micromachined material, a process that overcomes the stiction problem has to be developed. Thus, a new technique that combines wet-acetone dissolution and dry BrF3 dry etching has developed to overcome the stiction problem, which prevents Parylene microstructures from freestanding. The devices of mm*mm size with high yield are demonstrated using this technology. A thermopneumatic microvalve with a corrugated silicone/Parylene composite membrane is designed, fabricated, and tested for gas flows of several slpm and inlet pressures of tens of psi. The lowest power consumption to turn off the gas flow is determined to be 73mW. A silicone-based microfluidic coupler, initially designed for microvalve packaging, is also demonstrated for its ability to connect the external macrofluidic world to microfluidic devices. The demonstrated "quick-connect" microfluidic coupler has low leakage, is reusable, and can maintain good seal up to 60 psi. An in-channel microflow restrictor is also demonstrated with freestanding Parylene integration technology. The demonstrated restrictor can modulate flow at several tens of nl/min range with inlet pressures of several psi. The restrictor, although AC-actuated, can modulate the flow up to 50%. Finally, an electret microphone with thin-film Teflon AF is demonstrated. Parylene is shown to enhance the rigidity and yield of the microphone back plate. The demonstrated electret microphone has an open sensitivity of up to 45mV/Pa with a bandwidth of up to 10KHz.

In this paper, we propose a supporting method for developments of Web applications in order to support communication between users and developers. Our method combines three-layer architecture modeling of Web application and knowledge sharing technologies based on ontologies. The ontologies, which are used in the method and called enterprise application ontology (EAO), enable users and developers to form common understanding about system specification. EAO covers three aspects (legal aspect, business process, and software design) of business which is a candidate of development of a Web application. EAO includes three ontologies constructed from each of the three aspects. Concepts and structure of EAO are applied on page transition models, which are called Web Process Architecture, of a Web application. As a case study, we applied our method for a development of a ledger accounting system in a local government. And we confirmed that our method could support the development on the business analysis phase.

Applications of Induction Synchrotrons  

NASA Astrophysics Data System (ADS)

At present there are no plans to construct a new accelerator complex fully employing the super-bunch induction acceleration scheme. However, it appears attractive to retrofit many existing accelerator complexes based on RF technology to the induction synchrotron accelerator technology. It is possible to do so by replacing the RF devices without any changes in major components, such as the magnets, injection/extraction devices, vacuum systems, and beam monitoring instruments. Major laboratories in the world promote unique experimental capabilities using specific hadron accelerator complexes. It is interesting to explore how a delivered beam intensity or luminosity in these accelerator complexes is increased by this replacement and consequential for applications. This replacement appears attractive for the hadron accelerator complexes of Fermi National Accelerator Laboratory (8 GeV-Booster/120 GeV-Main Injector/Tevatron) [1], Brookhaven National Laboratory (1.2 GeV-Booster/28 GeV-AGS/RHIC) [2], and CERN (28-GeVPS/450 GeV-SPS/7 TeV-LHC) [3].

Mobile shearography in applications  

NASA Astrophysics Data System (ADS)

Modern optical methods such as digital shearography have attracted interest not only for laboratory investigations but also for applications on the factory floor because they can be sensitive, accurate, non-tactile and non-destructive. Optical inspection and measurement systems are more and more used in the entire manufacturing process. Shearography as a coherent optical method has been widely accepted as a useful NDT tool. It is a robust interferometric method to determine locations with maximum stress on various material structures. However, limitations of this technique can be found in the bulky equipment components, the interpretation of the complex shearographic result images and a barely solvable challenge at the work with difficult surfaces like dark absorbing or bright reflecting materials. We report a mobile shearography system that was especially designed for investigations at aircraft constructions. The great advantage of this system is the adjusted balance of all single elements to a complete measurement procedure integrated in a handy body. Only with the arrangement of all involved parameters like loading, laser source, sensor unit and software, it is feasible to get optimal measurement results. This paper describes a complete mobile shearographic procedure including loading and image processing facilities for structural testing and flaw recognition on aircrafts. The mobile system was successfully tested, e.g. with the up-to-date EADS multi-role combat aircraft Eurofighter.

Dorsal column stimulator applications  

PubMed Central

Background: Spinal cord stimulation (SCS) has been used to treat neuropathic pain since 1967. Following that, technological progress, among other advances, helped SCS become an effective tool to reduce pain. Methods: This article is a non-systematic review of the mechanism of action, indications, results, programming parameters, complications, and cost-effectiveness of SCS. Results: In spite of the existence of several studies that try to prove the mechanism of action of SCS, it still remains unknown. The mechanism of action of SCS would be based on the antidromic activation of the dorsal column fibers, which activate the inhibitory interneurons within the dorsal horn. At present, the indications of SCS are being revised constantly, while new applications are being proposed and researched worldwide. Failed back surgery syndrome (FBSS) is the most common indication for SCS, whereas, the complex regional pain syndrome (CRPS) is the second one. Also, this technique is useful in patients with refractory angina and critical limb ischemia, in whom surgical or endovascular treatment cannot be performed. Further indications may be phantom limb pain, chronic intractable pain located in the head, face, neck, or upper extremities, spinal lumbar stenosis in patients who are not surgical candidates, and others. Conclusion: Spinal cord stimulation is a useful tool for neuromodulation, if an accurate patient selection is carried out prior, which should include a trial period. Undoubtedly, this proper selection and a better knowledge of its underlying mechanisms of action, will allow this cutting edge technique to be more acceptable among pain physicians.

Nuclear microscopy: biomedical applications  

NASA Astrophysics Data System (ADS)

Recent developments in high energy ion beam techniques and technology have enabled the scanning proton microprobe (SPM) to make advances in biomedical research. In particular the combination of proton induced X-ray emission (PIXE) to measure the elemental concentrations of inorganic elements, Rutherford backscattering spectrometry (RBS) to characterise the organic matrix, and scanning transmission ion microscopy (STIM) to provide information on the density and structure of the sample, represents a powerful set of techniques which can be applied simultaneously to the specimen under investigation. This paper reviews briefly the biomedical work using the proton microprobe that has been carried out since the 2nd Int. Conf. on Nuclear Microprobe Technology and Applications held in Melbourne, 1990. Three recent and diverse examples of medical research are also presented from work carried out using the Oxford SPM. The first is a preliminary experiment carried out using human hair as a monitor for potential toxicity, using PIXE elemental mapping across the hair cross section to differentiate between elements contained within the hair and contamination from external sources. The second example is in the use of STIM to map individual cells in freeze-dried tissue, showing the possibility of the in situ microanalysis of cells and their extracellular environment. The third is the use of PIXE, RBS and STIM to identify and analyse the elemental constituents of neuritic plaque cores in untreated freeze-dried Alzheimer's tissue. This work resolves a current controversy by revealing an absence of aluminium levels in plaque cores at the 15 ppm level.

Applications of quantum cloning  

NASA Astrophysics Data System (ADS)

Quantum Cloning Machines (QCMs) allow for the copying of information, within the limits imposed by quantum mechanics. These devices are particularly interesting in the high-gain regime, i.e., when one input qubit generates a state of many output qubits. In this regime, they allow for the study of certain aspects of the quantum to classical transition. The understanding of these aspects is the root of the two recent applications that we will review in this paper: the first one is the Quantum Cloning Radiometer, a device which is able to produce an absolute measure of spectral radiance. This device exploits the fact that in the quantum regime information can be copied with only finite fidelity, whereas when a state becomes macroscopic, this fidelity gradually increases to 1. Measuring the fidelity of the cloning operation then allows to precisely determine the absolute spectral radiance of the input optical source. We will then discuss whether a Quantum Cloning Machine could be used to produce a state visible by the naked human eye, and the possibility of a Bell Experiment with humans playing the role of detectors.

NGI performance for teleradiology applications  

NASA Astrophysics Data System (ADS)

Tele-medical imaging applications require low cost, and high-speed backbone wide area networks (WAN) to carry large amount of imaging data for rapid turn around interpretation. Current low cost commercially WAN is too slow for medical imaging applications, while high speed WAN is too costly. The next generation Internet (NGI) or Internet2 is federal initiatives for the integration of higher speed backbone communication networks (up to 2.4 Gbits/sec) as a means to replace the current inadequate Internet for many applications including medical imaging. This paper describes our preliminary experience of connecting to Internet2 for teleradiology application. A case study is given for the NGI WAN connection between Childrens Hospital Los Angeles and National Library of Medicine. NGI WAN performance for different image modalities, measured in throughput rate and application response time, were obtained and then compared to the T1 WAN connection between Childrens Hospital Los Angeles and Saint John's Health Center Santa Monica.

Functionalized carbon nanotubes: biomedical applications.  

PubMed

Carbon nanotubes (CNTs) are emerging as novel nanomaterials for various biomedical applications. CNTs can be used to deliver a variety of therapeutic agents, including biomolecules, to the target disease sites. In addition, their unparalleled optical and electrical properties make them excellent candidates for bioimaging and other biomedical applications. However, the high cytotoxicity of CNTs limits their use in humans and many biological systems. The biocompatibility and low cytotoxicity of CNTs are attributed to size, dose, duration, testing systems, and surface functionalization. The functionalization of CNTs improves their solubility and biocompatibility and alters their cellular interaction pathways, resulting in much-reduced cytotoxic effects. Functionalized CNTs are promising novel materials for a variety of biomedical applications. These potential applications are particularly enhanced by their ability to penetrate biological membranes with relatively low cytotoxicity. This review is directed towards the overview of CNTs and their functionalization for biomedical applications with minimal cytotoxicity. PMID:23091380

Apparatus for coating selected portions of the troughs of a corrugated pipe within an adhesive includes a support disposed within the pipe with a reservoir containing the adhesive disposed on the support. A pump, including a spout, is utilized for supplying the adhesive from the reservoir to a trough of the pipe. A rotatable applicator is supported on the support and contacts the trough of the pipe. The applicator itself is sized so as to fit within the trough, and contacts the adhesive in the trough and spreads the adhesive in the trough upon rotation. A trough shield, supported by the support and disposed in the path of rotation of the applicator, is utilized to prevent the applicator from contacting selected portions of the trough. A locator head is also disposed on the support and provides a way for aligning the spout, the applicator, and the trough shield with the trough.

MIDACO on MINLP space applications  

NASA Astrophysics Data System (ADS)

A numerical study on two challenging mixed-integer non-linear programming (MINLP) space applications and their optimization with MIDACO, a recently developed general purpose optimization software, is presented. These applications are the optimal control of the ascent of a multiple-stage space launch vehicle and the space mission trajectory design from Earth to Jupiter using multiple gravity assists. Additionally, an NLP aerospace application, the optimal control of an F8 aircraft manoeuvre, is discussed and solved. In order to enhance the optimization performance of MIDACO a hybridization technique, coupling MIDACO with an SQP algorithm, is presented for two of these three applications. The numerical results show, that the applications can be solved to their best known solution (or even new best solution) in a reasonable time by the considered approach. Since using the concept of MINLP is still a novelty in the field of (aero)space engineering, the demonstrated capabilities are seen as very promising.

Application efficacy for comparing energy demand in lighting applications  

NASA Astrophysics Data System (ADS)

The light-emitting diode (LED) is a rapidly evolving, energy-efficient light source technology that holds promise to address the increasing need for energy conservation. However, the common belief that a high-efficacy light source equates to lower energy demand in application is incorrect. Generally, when a new light source technology replaces an existing light source in an application and claims energy savings, the inherent assumption is that all of the requirements of the application are met. In the case of directional lighting applications, what matters ultimately is the amount of luminous flux illuminating the task area. Therefore, when quantifying the performance of a luminaire, ideally one must consider only the amount of flux reaching the task area and the total power demanded. The objective of this paper is to introduce an alternative concept, application efficacy. This paper will demonstrate the concept's usefulness and proposed metrics for three different lighting applications-under-cabinet task lighting, refrigerated display case lighting, and outdoor parking lot lighting-and show how it better relates to energy demand. Details of laboratory experiments and software analysis along with data are presented for the three applications.

Adaptive Reactive Rich Internet Applications  

NASA Astrophysics Data System (ADS)

Rich Internet Applications significantly raise the user experience compared with legacy page-based Web applications because of their highly responsive user interfaces. Although this is a tremendous advance, it does not solve the problem of the one-size-fits-all approach1 of current Web applications. So although Rich Internet Applications put the user in a position to interact seamlessly with the Web application, they do not adapt to the context in which the user is currently working. In this paper we address the on-the-fly personalization of Rich Internet Applications. We introduce the concept of ARRIAs: Adaptive Reactive Rich Internet Applications and elaborate on how they are able to adapt to the current working context the user is engaged in. An architecture for the ad hoc adaptation of Rich Internet Applications is presented as well as a holistic framework and tools for the realization of our on-the-fly personalization approach. We divided both the architecture and the framework into two levels: offline/design-time and online/run-time. For design-time we explain how to use ontologies in order to annotate Rich Internet Applications and how to use these annotations for conceptual Web usage mining. Furthermore, we describe how to create client-side executable rules from the semantic data mining results. We present our declarative lightweight rule language tailored to the needs of being executed directly on the client. Because of the event-driven nature of the user interfaces of Rich Internet Applications, we designed a lightweight rule language based on the event-condition-action paradigm.2 At run-time the interactions of a user are tracked directly on the client and in real-time a user model is built up. The user model then acts as input to and is evaluated by our client-side complex event processing and rule engine.

Silicon applications in photonics  

NASA Astrophysics Data System (ADS)

Silicon technology enabled the miniaturization of computers and other electronic system for information storage, transmission and transformation allowing the development of the Knowledge Based Information Society. Despite the fact that silicon roadmap indicates possibilities for further improvement, already now the speed of electrons and the bandwidth of electronic circuits are not sufficient and photons are commonly utilized for signal transmission through optical fibers and purely photonic circuits promise further improvements. However materials used for these purposes II/V semiconductor compounds, glasses make integration of optoelectronic circuits with silicon complex an expensive. Therefore research on light generation, transformation and transmission in silicon is very active and recently, due to nanotechnology some spectacular results were achieved despite the fact that mechanisms of light generation are still discussed. Three topics will be discussed. Porous silicon was actively investigated due to its relatively efficient electroluminescence enabling its use in light sources. Its index of refraction, differs considerably from the index of silicon, and this allows its utilization for Bragg mirrors, wave guides and photonic crystals. The enormous surface enables several applications on medicine and biotechnology and in particular due to the effective chemo-modulation of its refracting index the design of optical chemosensors. An effective luminescence of doped and undoped nanocrystalline silicon opened another way for the construction of silicon light sources. Optical amplification was already discovered opening perspectives for the construction of nanosilicon lasers. Luminescences was observed at red, green and blue wavelengths. The used technology of silica and ion implantation are compatible with commonly used CMOS technology. Finally the recently developed and proved idea of optically pumped silicon Raman lasers, using nonlinearity and vibrations in the material to produce optical gain will be described.

Applications of multilayer optics  

NASA Astrophysics Data System (ADS)

Recent development of multilayer mirror and its applications in extreme ultraviolet (EUV), soft X-ray ranges in China was reviewed in this paper. Three types of multilayer mirrors were developed with special performance for dense plasma diagnostics, EUV astronomical observation. Firstly, dual-periodic W/B4C multilayer mirror was designed for Kirkpatrick-Baez (K-B) microscopy working at TiK? line (4.75 keV), which is highly reflective both at hard X-ray (CuK? line at 8.05 keV) and soft X-ray (4.75 keV). Using this mirror, the K-B system can be aligned conveniently in air using hard X-ray instead of in vacuum. The second mirror is aperiodic Mg/SiC multilayer, also a bi-functional mirror with high reflectivity for He-II emission line (30.4 nm) but suppressing He-I emission line (58.4 nm) in astronomy observation, which will replace the traditional combination of periodic multilayer and the fragile film filter. This will be more safe in satellite launching. The third mirror is Mo/Si periodic multilayer, depositing on a parabolic substrate with diameter of 230 mm, which is designed for EUV telescope for imaging of solar corona by selecting Fe-XII emission (19.5 nm). The uniformity of lateral layer thickness distribution is within ±0.3% along the diameter of mirror, measured by X-ray reflectometry. The measured peak reflectivity is 42% at the wavelength of 19.5 nm. All these multilayer mirrors were prepared by using magnetron sputtering system in our group.

Nanotechnology: Principles and Applications  

NASA Astrophysics Data System (ADS)

Nanotechnology is one of the leading scientific fields today since it combines knowledge from the fields of Physics, Chemistry, Biology, Medicine, Informatics, and Engineering. It is an emerging technological field with great potential to lead in great breakthroughs that can be applied in real life. Novel nano- and biomaterials, and nanodevices are fabricated and controlled by nanotechnology tools and techniques, which investigate and tune the properties, responses, and functions of living and non-living matter, at sizes below 100 nm. The application and use of nanomaterials in electronic and mechanical devices, in optical and magnetic components, quantum computing, tissue engineering, and other biotechnologies, with smallest features, widths well below 100 nm, are the economically most important parts of the nanotechnology nowadays and presumably in the near future. The number of nanoproducts is rapidly growing since more and more nanoengineered materials are reaching the global market The continuous revolution in nanotechnology will result in the fabrication of nanomaterials with properties and functionalities which are going to have positive changes in the lives of our citizens, be it in health, environment, electronics or any other field. In the energy generation challenge where the conventional fuel resources cannot remain the dominant energy source, taking into account the increasing consumption demand and the CO2 emissions alternative renewable energy sources based on new technologies have to be promoted. Innovative solar cell technologies that utilize nanostructured materials and composite systems such as organic photovoltaics offer great technological potential due to their attractive properties such as the potential of large-scale and low-cost roll-to-roll manufacturing processes The advances in nanomaterials necessitate parallel progress of the nanometrology tools and techniques to characterize and manipulate nanostructures. Revolutionary new approaches in nanometrology will be required in the near future and the existing ones will have to be improved in terms of better resolution and sensitivity for elements and molecular species. Finally, the development of specific guidance for the safety evaluation of nanotechnology products is strongly recommended.

RPCs in biomedical applications  

NASA Astrophysics Data System (ADS)

We are studying possible applications of Resistive Plate Chambers (RPCs) in the biomedical domain such as Positron Emission Tomography (PET). The use of RPCs in PET can provide several improvements on the usual scintillation-based detectors. The most striking features are the extremely good spatial and time resolutions. They can be as low as 50 ?m and 25 ps respectively, to be compared to the much higher intrinsic limits in bulk detectors. Much efforts have been made to investigate suitable materials to make RPCs sensitive to 511 keV photons. For this reason, we are studying different types of coating employing high Z materials with proper electrical resistivity. Later investigations explored the possibility of coating glass electrodes by mean of serigraphy techniques, employing oxide based mixtures with a high density of high Z materials; the efficiency is strongly dependent on its thickness and it reaches a maximum for a characteristic value that is a function of the compound (usually a few hundred microns). The most promising mixtures seem to be PbO, Bi2O3 and Tl2O. Preliminary gamma efficiency measurements for a Multigap RPC prototype (MRPC) are presented as well as simulations using GEANT4-based framework. The MRPC has 5 gas gaps; their spacings are kept by 0.3 mm diameter nylon fishing line, electrodes are made of thin glasses (1 mm for the outer electrodes, 0.15 0.4 mm for the inner ones). The detector is enclosed in a metallic gas-tight box, filled with a C2H2F4 92.5%, SF6 2.5%, C4H10 5% mixture. Different gas mixtures are being studied increasing the SF6 percentage and results of efficiency as a function of the new mixtures will be presented.

The article reports upon the characteristics of 300 abortion applicants in Arkansas manifesting significant stress from unwanted pregnancy between May 1, 1970 and June 30, 1971. The sample is limited by the fact that all of these women had been willing to seek medical aid. Patients ranged from ages 13-47, 131 of them ages 17-21. 35% had had some college education; another 29% were high school graduates. 50.6%, 20.6%, and 27.3% were single, divorced, and married, respectively. 59.6% of the patients were primiparas. 18.3%, 9.6%, and 12.3% were classified as being neurotic, having psychophysiologic tendencies (gastrointestinal problems, obesity, chronic headaches), and having sociopathic features (passive-aggressive, frankly rebellious, delinquent, antisocial, alcoholic), respectively. 12 women had noticeable schizoid features; 4 women had mildly active schizophrenia. Fathers of the women were usually blue-collar workers (55.3%) or white-collar workers (24.6%). The most frequent ordinal sibling position among the women was oldest child (38%). Parental instability (1 or both parents lost through death, divorce, father usually away working, chronic alcoholism, etc.) was reported by 39.6% of the patients. Patients' attitudes toward the unwanted pregnancy included dislike of inexpediency of the situation (82.6%), self-depreciation (55.6%), and aversion (28.6%). Precipitated psychiatric disorders were for the greatest part mild. Manifesting symptoms included depression (66.7%), anxiety (21%), and mixed anxiety and depression (12.2%). Suicidal threats and gestures were made by 22 and 8 patients, respectively. In summary, the study reveals a group of predominantly Caucasian women from unstable, middle-class urban families who were going through an adjustment reaction to adolescence or adult life.

Proteomics: Technology and Applications  

SciTech Connect

This meeting took place at the Keystone, Colorado resort from March 25-30, 2003. It was attended by 206 participants, of which 35 were students; 39% of attendees submitted abstracts. The meeting had 30% returning attendees and 70% new attendees. The group of speakers was composed of internationally recruited junior and senior experts in their respective fields. The group included representatives from academia and the private sector, highlights the convergence of proteomics efforts in the two sectors. The completion of the genome sequences of a large number of prokaryotic and eukaryotic species has catalyzed new research approaches to study the structure, function and control of biological processes. They are characterized by the systematic and in many cases quantitative analysis of all the molecules of a particular type expressed by a cell or tissue. The systematic analysis of proteins has been terms ''proteomics''. In an initial phase, most of the proteomics efforts were focused on large-scale protein identification. More recently, the objectives and technologies of proteomics have been diversified and expanded. Current proteomics research attempts to systematically and, where applicable, quantitatively determine the many properties of proteins and their biological function, including: protein abundance, state of modification, specific activity, interaction with other biomolecules, half-life, subcelluar location, structure and more. Significant current challenges include the development of suitable technologies to determine these properties on a proteome-wide scale, the interpretation of the large amounts of data obtained, and the integration of different types of data into a coherent model describing a biological process. The scientific program of the meeting intended to provide an up-to-date overview of the breadth of proteomics research and of emerging and mature technologies. Special emphasis was placed on discussing how proteomics technologies intersect with biological and clinical research. This was accomplished by bringing together leading experts from the different areas of proteomics research with biologists applying these technologies. Additionally, several talks featured comparisons of work in model systems and in mammalian cells, and other discussed computational approaches to mine large datasets of proteomic results in order to obtain biological insights into various processes.

REGIS Geohydrological Application System  

NASA Astrophysics Data System (ADS)

The Netherlands Institute of Applied Geoscience TNO - National Geological Survey (TNO-NITG) has been administrating the national database on groundwater and subsurface information for over a half of century. Since 1990 a database is accompanied by a geohydrological application system REGIS, developed for processing, visualization and interpretation of geohydrological and other data relevant for groundwater management. Being upgraded continuously, REGIS (version 3.1) is nowadays a mature system, widely used in The Netherlands and abroad. Technologically, REGIS is a combination of an Oracle database and ArcView GIS, having a number of specific REGIS extensions. A central REGIS window contains a topographic base map and displays the spatial features. Additional screens are provided for visualisation of time series, lithological columns, monitoring wells and other data available in REGIS. The screens are fully integrated, so that a single action on one screen (e.g. selecting a monitoring well on a topographic map) is enough to access a complementary screen (containing technical well data). REGIS has a standard functionality for importing monitoring data and spatial data sets that can be supplied by TNO-NITG for any area in The Netherlands. Nevertheless, any spatial data set formatted in a standardised manner can be imported into REGIS. Once entered, data can be selected, checked (by using built-in quality assurance control) and modified if required. Having a basic data set available, REGIS uses a unique mapping procedure to generate a 3-D subsurface model. The model is based on borehole data, geophysical well logging, geo-electrical soundings and well pump test data. These "basic" data are contained in a Column Module, whereas a Layer Module stores the model layers generated by data processing. A standard link between the modules enables not only an efficient management of generated layers but also an easy preparation of vertical cross-sections. Additionally, several REGIS modules have been developed to enable management of specific data (e.g. Surface Water Module) or to provide specific functionalities (such as Model Coupling Module). Due to its continuous development and extension, REGIS has become too comprehensive for some less-complex groundwater analysis. For that reason TNO-NITG is preparing development of three new REGIS versions, namely: light, basic and advanced.

REGIS Geohydrological Application System  

NASA Astrophysics Data System (ADS)

The Netherlands Institute of Applied Geoscience TNO - National Geological Survey (TNO-NITG) has been administrating the national database on groundwater and subsurface information for over a half of century. Since 1990 a database is accompanied by a geohydrological application system REGIS, developed for processing, visualization and interpretation of geohydrological and other data relevant for groundwater management. Being upgraded continuously, REGIS (version 3.1) is nowadays a mature system, widely used in The Netherlands and abroad. Technologically, REGIS is a combination of an Oracle database and ArcView GIS, having a number of specific REGIS extensions. A central REGIS window contains a topographic base map and displays the spatial features. Additional screens are provided for visualisation of time series, lithological columns, monitoring wells and other data available in REGIS. The screens are fully integrated, so that a single action on one screen (e.g. selecting a monitoring well on a topographic map) is enough to access a complementary screen (containing technical well data). REGIS has a standard functionality for importing monitoring data and spatial data sets that can be supplied by TNO-NITG for any area in The Netherlands. Nevertheless, any spatial data set formatted in a standardised manner can be imported into REGIS. Once entered, data can be selected, checked (by using built-in quality assurance control) and modified if required. Having a basic data set available, REGIS uses a unique mapping procedure to generate a 3-D subsurface model. The model is based on borehole data, geophysical well logging, geo-electrical soundings and well pump test data. These 'basic' data are contained in a Column Module, whereas a Layer Module stores the model layers generated by data processing. A standard link between the modules enables not only an efficient management of generated layers but also an easy preparation of vertical cross-sections. Additionally, several REGIS modules have been developed to enable management of specific data (e.g. Surface Water Module) or to provide specific functionalities (such as Model Coupling Module). Due to its continuous development and extension, REGIS has become too comprehensive for some less-complex groundwater analysis. For that reason TNO-NITG is preparing development of three new REGIS versions, namely: light, basic and advanced. The new REGIS versions will be technologically upgraded as well; probably a major technical advancement concerns the replacement of current ArcView with ArcGIS. Additional information on current and intended REGIS developments will be made available during (and after, if required) the presentation at the Assembly.

Nanoporous metals and applications  

NASA Astrophysics Data System (ADS)

This dissertation consists of three parts: fabrication of nanoporous metal thin films, study of the dealloying models and Kinetic Monte Carlo simulation and the fabrication of a hydrogen sensor using nanoporous platinum thin films. In the first part of the dissertation, we reported the fabrication of different metallic nanoporous films by dealloying and studied their structural properties. Nanoporous films are of interest in a wide range of applications such as catalysis, sensing, microfluidic control and filtration. The objective of this study is to synthesize and characterize different nanoporous structures by chemical etching. The experiments were conducted on four different materials: 6-carat white gold leaf, solder wire, imitation Italian gold leaf and sputtered CuPt alloy thin films. The dealloyed CuPt films were coarsened at different temperatures to obtain pore sizes ranging from a few nanometers to tens of nanometers. The porous films have been analyzed by field emission scanning electron microscopy (FESEM), energy dispersive x-ray spectroscopy (EDX), and high quality x-ray mapping (XRM). Our experiments resulted in sponge-like Au nanoporous of 10-200 nm, Pb pores of 10-300 nm, and Cu pores of 10-100 nm. The results showed a technically improved fabrication of different nanoporous materials with large surface area and well defined pore morphology. The second part of the dissertation was the study of various models to explain the evolution of porosity by dealloying and the development of a KMC simulation model to verify experimental results. A KMC model was developed to simulate the dealloying of CuPt in H2SO4 and coarsening of the dealloyed film in vacuum at various temperatures. The output was compared with the experimental results. The third part of the dissertation was the fabrication of a nanoporous platinum (np-Pt) thin film based hydrogen sensor. A sensor device with four electrodes was fabricated on the np-Pt thin films using a stainless steel mask by sputtering copper. The electrical characteristics of the sensor exhibit marked sensitivity or current changes in the presence of hydrogen. A resistance transient method was used to measure the sensitivity of these thin films in different hydrogen concentrations using air as the carrier gas. The effect of temperature and pore size on the sensitivity and response time were studied. Sensitivity of 3.5% was obtained for 1000ppm of hydrogen at room temperature for the largest fabricated pore size of 35nm. The fabricated sensors showed quick response and repeatability in their sensing mechanism. The results demonstrate that np-Pt thin films configured as a gas sensor have high sensitivity to hydrogen.

Different proposed applications of bacteriorhodopsin.  

PubMed

Bacteriorhodopsin (BR) is an integral membrane protein found in "purple membrane" (the Archaea cell membrane) mainly in Halobacteria. This protein absorbs green light (wavelength 500-650 nm, with the absorption maximum at 568 nm) and converts it into an electrochemical gradient. This gradient in turn is used for ATP production. The ability of BR to convert light energy into chemical energy or sunlight into electricity has been used in different applications mainly optical appliances but also for therapeutic/medical applications and research. This review surveys some of these applications that have been patented in the last five years. PMID:21306298

A new high intensity focused ultrasound applicator for surgical applications.  

PubMed

Improved high-intensity focused ultrasound (HIFU) surgical applicators are required for use in a surgical environment. We report on the performance and characteristics of a new solid-cone HIFU applicator. Previous HIFU devices used a water-filled stand-off to couple the ultrasonic energy from the transducer to the treatment area. The new applicator uses a spherically-focused element and a solid aluminum cone to guide and couple the ultrasound to the tissue. Compared with the water-filled applicators, this new applicator is simpler to set up and manipulate, cannot leak, prevents the possibility of cavitation within the coupling device, and is much easier to sterilize and maintain during surgery. The design minimizes losses caused by shear wave conversion found in tapered solid acoustic velocity transformers operated at high frequencies. Computer simulations predicted good transfer of longitudinal waves. Impedance measurements, beam plots, Schlieren images, and force balance measurements verified strong focusing and suitable transfer of acoustic energy into water. At the focus, the -3 dB beam dimensions are 1.2 mm (axial) x 0.3 mm (transverse). Radiation force balance measurements indicate a power transfer efficiency of 40%. In vitro and in vivo tissue experiments confirmed the applicator's ability to produce hemostasis. PMID:11367806

Intrinsic wavelet and frame applications  

NASA Astrophysics Data System (ADS)

There are intrinsic wavelet applications, by which we mean mathematical modeling of a physical phenomenon in which wavelet theory is the most natural quantitative means of explaining the phenomenon. This is not the same as the invaluable use of dyadic wavelets, say, as a tool with which to zoom-in or -out with regard to multi-scale phenomena. An example of an intrinsic wavelet application is wavelet auditory modeling (WAM). WAM is analyzed herein, and a natural excursion, one of many possibilities, is taken from WAM to applications of finite frames. This path includes the role of the Discrete Fourier Transform (DFT) in WAM, the emergence of DFT frames, and their use in analyzing ?? quantization, which itself is a staple in audio engineering as well as in a host of other applications.

Functional services for application development  

NASA Astrophysics Data System (ADS)

A core system architecture is proposed following a functional model that separates the application subsystem into three functional groups, namely hypermedia, management, and communication, and provides an application development support system. This architecture provides access to storage systems (information provision engines) independently of their internal per site structure. Once the core system building blocks are available at the information provider sites, different applications can be easily developed on top of the functional services provided by the core system. These applications, although using the same core system, will be different in the way the functionalities are provided to the users, as they may have quite different requirements in how they want to search, use information, present, customize, collaborate, etc.

Applications of Nuclear Resonance Fluorescence  

SciTech Connect

Nuclear Resonance Fluorescence (NRF) has the potential of addressing a wide variety of applications, which require isotopic and/or elemental information about a sample. We have investigated a variety of non-proliferation applications that may be addressed by NRF. From these applications, we have selected two, measuring uranium enrichment in UF6 cylinders and material verification in dismantlement, to investigate in more detail. Analytical models have been developed to evaluate these applications, and test measurements have been conducted to validate those models. We found that it is unlikely with current technology to address the requirements for UF6 cylinder enrichment measurements. In contrast, NRF is a very promising approach for material verification for dismantlement.

Trends in Mobile Application Development  

NASA Astrophysics Data System (ADS)

Major software companies, such as Apple and Google, are disturbing the relatively safe and established actors of the mobile application business. These newcomers have caused significant structural changes by imposing and enforcing their own rules for the future of mobile application development. The implications of these changes do not only concern the mobile network operators and mobile phone manufacturers. This changed environment also brings additional opportunities and constraints for current mobile application developers. Therefore, developers need to assess what their options are and how they can take advantages of these current trends. In this paper, we take a developer’s perspective in order to explore how the structural changes will influence the mobile application development markets. Moreover, we discuss what aspects developers need to take into account in order to position themselves within the current trends.

Applicant analysis: 2001 entering class.  

PubMed

There were 7,412 applicants to the entering dental school class of 2001. This is 4.6 percent less than the number of applicants to the entering class of 2000. Since the peak of dental school applicants in 1997 (at 9,829), the number of applicants has declined 24.6 percent. (This decline is most similar to the 25.8 percent decline that has occurred in medical school applicants since their peak of applicants in 1996, at 46,968.) With the decline in applicants and a slight increase in first-time, first-year enrollees, 57.6 percent of the dental school applicants were enrolled in 2001. This is up from 54.5 percent in 2000. Dental schools reported 4,267 first-time, first-year enrollees in 2001. This is an increase of thirty-three first-time, first-year enrollees over the number reported in 2000 and only an increase of fifty-eight over the last two years. Since 1989, when dental school enrollment once again began to increase, the number of first-time, first-year enrollees has increased 14.9 percent. (Total first-year enrollment, which includes first-time enrollees and repeat students, has increased 10.8 percent since 1989.) The number of applicants per first-time, first-year positions was 1.74 in 2001. It was 2.31 in 1997. (The most recent low was 1.34 in 1989.) The average of the GPA and DAT scores of the first-time, first-year enrollees in 2001 were all slightly higher than they were in 2000. Women were approximately 42 percent of the applicants and first-time, first-year enrollees in 2001, up slightly from 2000. Underrepresented minorities comprised over 12.6 percent of the applicants and 11.9 percent of the first-time, first-year enrollees, also up slightly from 2000. PMID:12856969

Realistic engineering simulation data often have features that are not optimally resolved due to practical limitations on mesh resolution. To be useful to application engineers, vortex characterization techniques must be sufficiently robust to handle realistic data with complex vortex topologies. In this paper, we present enhancements to the vortex topology identification component of an existing vortex characterization algorithm. The modified techniques are demonstrated by application to three realistic data sets that illustrate the strengths and weaknesses of our approach.

This paper reviews the processing of these materials and the properties relevant to engine applications. These properties include strength, toughness and damping capacity. Laminates can have very attractive properties relative to other structural materials for weight critical applications requiring high stiffness, strength and fracture toughness. The structure-property correlations that determine these properties are described.

Bipolar spintronics: Fundamentals and applications  

Microsoft Academic Search

By incorporating spin-dependent properties and magnetism in semiconductor structures, new applications can be considered which go beyond magnetoresistive effects in metallic systems. Notwithstanding the prospects for spin\\/magnetism-enhanced logic in semiconductors, many important theoretical, experimental, and materials challenges remain. Here we discuss the challenges for realizing a particular class of associated applications and our proposal for bipolar spintronic devices in which

Plant genetics for forensic applications.  

PubMed

An emerging application for plant DNA fingerprinting and barcoding involves forensic investigations. Examples of DNA analysis of botanical evidence include crime scene analysis, identifying the source of commercial plant products, and investigation of trade in illicit drugs. Here, we review real and potential applications of DNA-based forensic botany and provide a protocol for microsatellite genotyping of leaf material, a protocol that could be used to link a suspect to a victim or to a crime scene.

Active Replication of Multithreaded Applications  

Microsoft Academic Search

Software-based active replication is a well-known techniq ue for providing fault tolerance using space redundancy and fault- masking. However, much of the recent research in software re plication has yet to be demonstrated using large, real-worl d applications, and in particular, multithreaded applicati ons. While multithreading can improve performance, thread scheduling is a source of nondeterminism in application behavior. Exis

Contribution a l'etude du comportement de dalles de ponts en beton arme de barres en PRF soumises a des charges concentrees simulant les charges de roues  

NASA Astrophysics Data System (ADS)

Au cours des dernieres annees, la deterioration des structures en beton arme a pris une ampleur sans precedent, et ce, malgre le fait que leur duree de vie en service initialement prevue est loin d'etre atteinte. La corrosion de l'armature d'acier est un des principaux facteurs reduisant la duree de vie des ponts en beton arme d'acier. Par ailleurs, l'armature en materiaux composites de polymeres renforces de fibres (PRF) constitue une solution a l'armature metallique afin de pallier au probleme de la corrosion d'acier et a la deterioration des structures en beton arme. Aussi, les barres d'armature en materiaux composites de PRF possedent une resistance en traction elevee (environ 2 a 6 fois la limite elastique de l'acier d'armature conventionnel), ce qui leur permet de constituer un renforcement structural attrayant pour les structures en beton. Le comportement d'elements structuraux en beton arme de barres en PRF est different de ceux en beton arme de barres d'acier. En effet, les barres en PRF possedent un module d'elasticite relativement plus faible que celui de l'acier et ont des proprietes d'adherence differentes de celles des barres d'acier. L'utilisation des barres d'armature en PRF pour armer les dalles de tabliers de ponts se concretise de plus en plus avec l'avancement des recherches dans ce domaine. La recherche entamee dans le cadre de cette these s'inscrit dans un programme de travaux realises au sein de la Chaire de recherche CRSNG/Industrie sur les Materiaux composites novateurs en PRF pour les infrastructures au departement de genie civil a l'Universite de Sherbrooke. Le comportement de membrures en beton arme de PRF soumis a des sollicitations mecaniques constitue un des principaux axes de recherche. Dans le cadre de cette these, une serie d'essais a ete effectuee sur huit dalles de ponts a confinement interne a grande echelle. Les parametres des essais comprennent: (1) l'epaisseur de la dalle, (2) le type et le taux d'armature transversale de l'assemblage inferieur, (3) la resistance en compression du beton, et (4) le taux d'armature dans les autres directions (armatures transversale et longitudinale de l'assemblage superieur et l'armature longitudinale de l'assemblage inferieur). Lors des essais de chargement, les dalles ont ete supportees par deux poutrelles metalliques espacees de 2000 mm centre a centre et soumises a une charge statique concentree sur une aire de contact de 600 mm x 250 mm afin de simuler une charge de camion (87,5 kN--CL-625) et ce conformement au code Canadien sur le calcul des ponts routiers [CAN/CSA-S6-06]. Aussi, une analyse numerique du comportement des dalles testees sous charges est faite a l'aide d'un logiciel d'elements finis ADINA version 8.2. Les essais ont montre que toutes les dalles testees ont rompu par poinconnement, peu importe le parametre etudie. Aussi, une epaisseur de dalle de 175 mm repond aux exigences du Canadien sur le calcul des ponts routiers [CAN/CSA-S6-06]. Par ailleurs, les resultats ont montre que la resistance en compression du beton est un parametre qui influe sur la deflexion, les deformations dans les barres et l'ouverture de fissures. Enfin, les resultats des analyses numeriques effectuees corroborent avec ceux obtenus experimentalement. Mots cles. Dalle de ponts en beton, armature de PRF, charges statiques, flexion, deformations, poinconnement, elements finis.
