    Full Text Available Psychotic disorders are among the most complex medical conditions. Longitudinal cohort studies may offer further insight into determinants of functional outcome after a psychotic episode. This paper describes the Psychosis Recent Onset in GRoningen Survey (PROGR-S that currently contains data on 1076 early-episode patients with psychosis, including symptoms, personality, cognition, life events and other outcome determinants. Our goal in this report is to give an overview of PROGR-S, as a point of reference for future publications on the effect of cognition, personality and psychosocial functioning on outcomes. PROGR-S contains an extensive, diagnostic battery including anamnesis, biography, socio-demographic characteristics, clinical status, drug use, neuropsychological assessment, personality questionnaires, and physical status tests. Extensive follow-up data is available on psychopathology, physical condition, medication use, and care consumption. Sample characteristics were determined and related to existing literature. PROGR-S (period 1997-2009, n = 718 included the majority of the expected referrals in the catchment area. The average age was 27 (SD = 8.6 and two-thirds were male. The average IQ was lower than that in the healthy control group. The majority had been diagnosed with a psychotic spectrum disorder. A substantial number of the patients had depressive symptoms (479/718, 78% and current cannabis or alcohol use (465/718, 75%. The level of community functioning was moderate, i.e. most patients were not in a relationship and were unemployed. The PROGR-S database contains a valuable cohort to study a range of aspects related to symptomatic and functional outcomes of recent onset psychosis, which may play a role in the treatment of this complex and disabling disorder. Results reported here show interesting starting points for future research. Thus, we aim to investigate long-term outcomes on the basis of cognition, personality, negative

    The use of hydraulic fracturing has grown tremendously since its introduction over 50 years ago. Most wells in low permeability reservoirs are not economic without hydraulic fracture stimulation. Hydraulic fracturing is also seeing increasing use in high permeability applications. The success of this technology can be attributed to the great strides made in three areas: hydraulic fracture theory and modeling, improved surface and subsurface equipment and advanced fluid systems and proppers. However, industry still has limited capabilities when it comes to determining the geometry of the created hydraulic fracture. This limitation, in turn places limits on the continued improvement of hydraulic fracturing as a means to optimize productivity and recovery. GRI's Advanced Hydraulic Fracture Diagnostics Program has developed two new technologies, microseismic hydraulic fracture mapping and downhole tilt-meter hydraulic fracture mapping, to address this limitation. These two technologies have been utilized to improve field development and reduce hydraulic fracturing costs. This paper reviews these technologies and presents case histories of their use. (author)

    2015-01-01

    This monograph presents a groundbreaking scholarly treatment of the German mathematician Jost Bürgi’s original work on logarithms, Arithmetische und Geometrische Progreß Tabulen. It provides the first-ever English translation of Bürgi’s text and illuminates his role in the development of the conception of logarithms, for which John Napier is traditionally given priority. High-resolution scans of each page of the his handwritten text are reproduced for the reader and as a means of preserving an important work for which there are very few surviving copies. The book begins with a brief biography of Bürgi to familiarize readers with his life and work, as well as to offer an historical context in which to explore his contributions. The second chapter then describes the extant copies of the Arithmetische und Geometrische Progreß Tabulen, with a detailed description of the copy that is the focus of this book, the 1620 “Graz manuscript”. A complete facsimile of the text is included in the next chapter, a...

Ces progrès interpellent quotidiennement médecins et personnel infirmier, posant des défis pour lesquels peu de réponses existent. Normes et valeurs s’actualisent en ces lieux où des enjeux entourant la vie, la “qualité” de vie, et la mort sont quotidiens. L’hôpital pédiatrique est certes un endroit où tous les espoirs sont permis. C’est aussi un lieu où la mort est à apprivoiser ; elle devient un choix, s’imposant rarement d’elle-même. Sur la base des témoignages des soignants et de nos propres observations, nous proposons une réflexion sur la ‘fin de vie’, objet d’un choix difficile, en dialogue avec la technologie qui la rend possible. Ces différentes voix témoigneront de rationalités parfois parallèles, convergentes ou divergentes, et des normes et valeurs qui s’affrontent, se rencontrent et se négocient dans l’espace social de la clinique.Stemming from an anthropological study of clinical practices in tertiary health care institutions, our paper focuses on challenges brought by medical and technological progress in paediatric intensive care units (acute and oncology units (chronic.

    échauffement climatique fournissent une forte motivation pour le développement de moyens de propulsion véhiculaires économes. Pour les camions, cette tâche est particulièrement difficile à accomplir du fait d’importantes contraintes de taille et de poids. L’hybridation est la seule approche qui puisse déboucher sur des progrès importants à court et moyen termes. En particulier, la configuration “hybride série” découple le moteur thermique des roues et permet une flexibilité complète dans le contrôle des points de fonctionnement moteur. De plus, la conversion et le stockage de l’énergie hydraulique fournissent une densité de puissance et un rendement excellents. Le défi technologique tient à la faible densité d’énergie de l’accumulateur hydraulique, et met en avant l’importance particulière du développement du gestionnaire de l’énergie. Il est communément admis qu’il faut maintenir le moteur au point de rendement maximum mais, si l’objectif ultime en terme énergétique consiste à optimiser drastiquement le rendement du moteur, ceci induit des phases transitoires fréquentes causant pour des moteurs diesels des effets opposés tant sur l’émission de particules que sur l’agrément de conduite. Par conséquent, nous proposons une méthodologie pour le superviseur d’énergie d’un système hybride, qui prend en compte 2 objectifs : la réduction de consommation et la réduction des émissions polluantes. Les économies de carburant sont prises en compte par une approche fondée sur la simulation, alors que l’étude de l’impact des phases transitoires du moteur sur les émissions de particules, est fondée sur un dispositif expérimental combinant modèles temps réel et moteur réel – l’EIL (Engine-In-the-Loop. Le dispositif EIL confirme que le contrôle de la répartition énergétique thermique/hydraulique de l’état de charge des batteries (SOC présente des avantages certains sur celui basé sur l’approche de contr

    domain and then may initiate some fracturing. In other cases, the sediment changes its loading path but stay at the elastoplastic yield surface. In this case the theoretical considerations are not valid anymore and fracture criteria should be defined in the plastic domain. Fracturation hydraulique à l'échelle des bassins sédimentaires Fracturation hydraulique à l'échelle des bassins sédimentaires Le calcul du tenseur des contraintes est déterminant pour pouvoir simuler la fracturation hydraulique à l'échelle des bassins sédimentaires. Ce calcul n'est généralement pas abordé dans les modèles de bassins en raison de la complexité du problème. Pour pouvoir estimer le tenseur des contraintes, nous sommes alors amenés à formuler les hypothèses suivantes: - une des contraintes principales est verticale et égale, en module, au poids des terrains sus-jacents ; - la contrainte horizontale se déduit de la contrainte verticale à partir d'un coefficient de report K0 qui est une fonction de la profondeur et du contexte géodynamique. La consolidation est supposée être le résultat à la fois de la compaction mécanique et de la compaction chimique. La compaction mécanique est principalement due au réarrangement mécanique des grains pendant l'enfouissement. Elle peut se simuler, à l'échelle macroscopique, par une rhéologie élasto-plastique. La compaction chimique est le résultat des mécanismes de pression-dissolution. Elle peut être simulée, à l'échelle macroscopique, par une rhéologie viscoplastique. La surface de charge est complètement définie par l'union de la surface de consolidation avec les différentes limites de rupture. Cette surface de charge est alors définie par six surfaces élémentaires qui représentent la compaction verticale, la compaction horizontale, la rupture verticale en traction, la rupture horizontale en traction, la rupture subverticale en cisaillement, et la rupture subhorizontale en cisaillement.

    Full Text Available La nécessité de réaliser, dans une couche mince et située à plus de 1000 m de profondeur, une communication hydraulique ou pneumatique entre deux sondages verticaux, a conduit à l'étude d'une méthode basée sur la fracturation hydraulique des puits à relier. Une telle approche suppose que l'on connaisse ou que l'on contrôle la direction des fractures développées. Les techniques actuelles ne permettant pas d'apprécier la direction de fracture avec une précision suffisante, la méthode proposée vise à influencer favorablement cette direction. Elle est basée sur une modification des contraintes effectives en place par une injection préalable de fluide dans les puits à relier. Les résultats obtenus au moyen de calculs analytiques et numériques à deux dimensions sont présentés, ainsi que les expériences réalisées sur un modèle physique en laboratoire. In a thin layer and at a depth of more than 1000 meters, the need to create a hydraulic or pneumatic communication between two vertical boreholes led to research on a method based on hydraulic fracturing in the wells to be linked. Such an approach supposes that the direction of the fractures thus created must be known or controlled. Current techniques cannot be used to assess fracture direction with sufficient accuracy. The method proposed here aims to have a favorable influence on this direction. It is based on making a change in the effective stresses in situ by the prior injection of fluid into the wells to be linked. The results obtained by two-dimensional analytical and digital computing are described together with the experiments performed on a physical model in the laboratory.

    Full Text Available This study aims to compare the suicide risk over the past decade following recent onset psychosis to findings from the eighties and nineties in the same catchment area and to identify predictors of suicide in the context of the Psychosis Recent Onset Groningen-Survey (PROGR-S. A medical file search was carried out to determine the current status of all patients admitted between 2000 and 2009. The suicide rate was compared with a study executed in 1973-1988 in the same catchment area. Predictors of suicide were investigated using Cox regression. The status of 424 of the 614 patients was known in July 2014. Suicide occurred in 2.4% of patients with psychosis disorders (n = 10; mean follow-up 5.6 years; 6 out of 10 suicides took place within two years. Within two decades, the suicide rate dropped from 11% (follow-up 15 years, 8.5% after 5 years to 2.4%. The Standardized Mortality Rate (SMR of suicides compared with the general population was 41.6. A higher age was the only significant predictor for suicide. Neuroticism, living situation, disorganized and negative symptoms, and passive coping style all showed a trend for significance. A significant reduction in the suicide rate was found for people with psychosis over the past decades. Given the high SMR, suicide research should be given the highest priority. Identifying predictors may contribute to further reduction of suicide among patients with psychosis.

    A review of the waste-disposal research and development carried out in the United States of America is given. The major research effort concerns the conversion of high-level liquid wastes into solids. At Hanford and Oak Ridge low-level wastes are disposed to the ground in pits, cribs and lagoons. Geochemical studies related to waste disposal are conducted at Hanford, Oak Ridge and the University of North Carolina. Experiments with soil columns ate described ; these are more effective for the decontamination of waste streams than either cribs or pits. The most suitable exchange materials for the soil columns are found to be vermiculite supported by rock phosphate and the latter supported by graded gravel. The progress of research work on the possibility of injecting radioactive liquid wastes into porous formations through deep wells and disposing of radioactive wastes in impermeable formations by hydraulic fracturing is outlined.

    Successful experiments have been done on the method described at Geneva in 1958. The process has been considerably improved: 1 - Initially, the caesium phospho tungstate precipitate was leached barium hydroxide in the centrifuge and this was followed by a distillation of ammonia in a concentrator. The barium hydroxide was then eliminated by carbonate precipitation and centrifugation. It has been proved that the ammonia distillation could be replaced by its evaporation during centrifugation, thus eliminating the need of a concentrator. It was then possible to carry out the carbonation on the solide-liquid mixture produced by the baryte water leaching. 2 - In applying the above process to the treatment of solutions derived from uranium molybdenum fuels, concentrating is to be recommended in order to hold the molybdenum in solution by complexing it with phosphoric acid. This complexing process provides a suspension of zirconium phosphate and ammonium phospho tungstate. These are separated by passing into a basic medium which precipitates the zirconium oxide, then turning back to an acid medium; the end of the treatment remains unchanged. 3 - Studies carried out in several countries on the exchange properties of hetero-polyacid salts have always met with difficulties as a result of the poor mechanical properties of these substances. This difficulty has been overcome by wrapping the ammonium phospho tungstate in a zirconium phosphate matrix. The exchanger obtained possesses: satisfactory mechanical properties, - a capacity of 0.1 milli equivalent per gram in concentrated nitric acid solution. It can be eluted and regenerated by a solution of an ammonium salt. The procedure for recovery of these various fission products is briefly the following: extraction of rare earths by di-2-ethyl hexyl phosphoric acid into dodecane at pH 2, the chemical impurities being complexed by citric acid, extraction of most of the magnesium at pH 4 by the same solvents the solvent being saturated with magnesium in order to avoid as far as possible the extraction of strontium, extraction of strontium at pH 4. (author) [French] La methode decrite a Geneve en 1958 a ete experimentee avec succes. Des ameliorations importantes ont ete apportees a ce procede: 1 - Initialement, la precipitation phosphotungstique du cesium etait suivie d'une reprise a la baryte en centrifugeuse et d'une distillation de l'ammoniac dans un concentrateur. Ensuite, l'hydroxyde de baryum etait elimine par precipitation carbonique et centrifugation. 1 - Il a ete prouve que la distillation de l'ammoniac pouvait etre remplacee par une evaporation au cours de la centrifugation, ce qui supprime le concentrateur. Il a ensuite ete possible d'effectuer la carbonatation sur le melange solide-liquide provenant de l'attaque a la baryte. 2 - Pour appliquer le precedent procede au traitement des solutions provenant des combustibles uranium-molybdene, nous avons recommande une concentration qui maintient en solution le molybdene par complexation par l'acide phosphorique. Cette complexation fournit une suspension de phosphate de zirconium et de phosphotungstate d'ammonium. Ils sont separes en repassant en milieu basique qui fait precipiter la zircone, puis en revenant en milieu acide, la suite du traitement restant le meme. 3 - Les etudes sur les proprietes d'echange des sels d'hetero-polyacides poursuivies dans plusieurs pays ont toujours rencontre l'ecueil des mauvaises qualites mecaniques de ces produits. Cette difficulte a ete surmontee en emprisonnant le phosphotungstate d'ammonium dans une matrice en phosphate de zirconium. L'echangeur obtenu possede: - des proprietes mecaniques satisfaisantes - une capacite de 0,1 milliequivalent par gramme en milieu acide nitrique concentre. II est eluable et regenerable par une solution d'un sel d'ammonium. Le schema de recuperation de ces differents produits de fission est succinctement le suivant: - extraction des terres rares par l'acide di-2-ethyl hexyl phosphorique-dodecane a pH 2, les impuretes chimiques etant complexees par l'acide citrique. - extraction de la majeure partie du magnesium a pH 4 par le meme solvant, le solvant travaillant a saturation de magnesium pour eviter au maximum l'extraction du strontium. - extraction du strontium a pH 4.

    Abundant geochemical information can be acquired by analyzing the chemical compositions of petroleum geological samples. The information obtained from the analysis provides scientifical evidences for petroleum exploration. However, these samples are complicated and can be easily influenced by physical (e. g. evaporation, emulsification, natural dispersion, dissolution and sorption), chemical (photodegradation) and biological (mainly microbial degradation) weathering processes. Therefore, it is very difficult to analyze the petroleum geological samples and they cannot be effectively separated by traditional gas chromatography/mass spectrometry. A newly developed separation technique, comprehensive two-dimensional gas chromatography (GC x GC), has unique advantages in complex sample analysis, and recently it has been applied to petroleum geological samples. This article mainly reviews the research progres- ses in the last five years, the main problems and the future research about GC x GC applied in the area of petroleum geology.

    The search for radioactive tracers for water capable of percolating through permeable grounds without significant absorption has led to the choosing of two isotopes, bromine 82 (half-life 36 hours) and iodine (half-life 8 days), both {gamma} emitters; various combinations of other {gamma} emitters with longer half-lives have been tried but with only partial success. The recent progress in the dosage of tritium should make it possible to widen the field of application of this tracer which is unique in its kind. Being detectable at concentrations of 10{sup -6} to 10{sup -8} curies per cubic meter, the radioactive tracers are suitable for all the usual applications of conventional tracers; furthermore, some original techniques have been devised for measurements of flow, of reservoir capacity, of porosity and of permeability. Techniques based on the absorption and scattering of {gamma}-rays have also been developed for the measurement of the density, the humidity and the porosity of soils, and also for their analysis. Up to the present, radioactivity has been mainly applied to the study of oil-bearing formations. Furthermore, the study of the distribution of natural of thermonuclear tritium has contributed greatly to the study of the hydrological cycle. (author) [French] La recherche de traceurs radioactifs de l'eau susceptibles de circuler a travers les terrains permeables sans retention notable a abouti a la selection de deux isotopes, le brome 82 (periodes 36 heures) et l'iode (periode 8 jours), tous deux emetteurs {gamma}; diverses combinaisons mettant en jeu des emetteurs {gamma} de periode plus longue ont ete essayees, mais avec un succes partiel. Les progres recemment accomplis dans le dosage du tritium doivent permettre une rapide extension de l'emploi de ce traceur unique en son genre. Decelables a des concentrations de 10{sup -6} a 10{sup -8} curies par metre cube, les traceurs radioactifs se pretent a toutes les applications des traceurs classiques; de plus

    Full Text Available Un code numérique de simulation des distributions équipées de poussoirs hydrauliques a été développé. Le code est basé sur trois sous-modèles couplés : mécanique, hydraulique et physique. Le premier étudie la distribution comme un assemblage masses ressorts, le deuxième étudie le poussoir comme un organe hydraulique à part entière et le dernier permet d'étudier l'aération de l'huile et en particulier les phénomènes de dissolution. Une validation expérimentale a été menée sur un banc culasse alimenté par une huile mélangée à de l'air en proportions mesurées. L'instrumentation permettait de mesurer l'accélération de la tête de soupape, son déplacement au voisinage du siège et la force entre poussoir et soupape. Cette validation a montré que la simulation reflétait bien la réalité, notamment en ce qui concerne les effets de l'aération. A model of valvetrain equipped with a direct acting hydraulic lash adjuster (HLA is presented. As it is the cause of many problems, a possible aeration is taken into account. The main model is made of three submodels:1. The first one is a mechanical one with masses, springs and dampers and needs the cam laws and the pressure of the chamber of the HLA as data. 2. The second submodel is an hydraulic one. It studies the HLA chamber through the check valve flows, the leakage flow and the mechanical strains on the chamber oil. This submodel gives the chamber pressure to the first submodel. 3. The third submodel is a physical one and evaluates the instantaneous amount of air present in the chamber oil. It takes into account the arrival of new bubbles through the check valve and the mass exchanges (diffusion, dissolution between the bubbles and the oil bulk. This amount of air has a direct influence on the chamber pressure calculation made in the second submodel. Experimental validation of the model was conducted on an engine head. This engine head was feeded by an oil circuit in which

    A sub-scale experimental and numerical program has been carried out in order to improve the knowledge of vortex shedding driven pressure oscillations phenomena in segmented solid rocket motors. Full Navier-Stokes simulations have provided pressure amplitudes in the same range than the experimental ones, for different configurations of non-metallized propellant sub-scale motors having metallic restrictors or no restrictor on the last segment forward face. An original scenario has been proposed which rely mostly on surface vortex shedding originating on the burning surface of the propellant. This phenomenon is particularly present in the no-restrictor configuration but also in some configurations with metallic restrictors whose shape (bent versus non bent) has been identified as an influent parameter. First numerical computations of all the firing of a motor, done with SNPE MOPTI suite, shows instabilities zones very close to experimental ones. A new scenario proposed by ONERA relying on aluminum distributed combustion in surface vortex-shedding area is proposed to explain the levels of pressure oscillation obtained at full scale.

    Fundamental studies on turbulent atmospheric diffusion of finely divided particles, cannot remain on a purely theoretical basis. Further experimental studies must be considered. - In full scale, from accidental and induced releases. - On a reduced scale, in aerodynamic wind tunnels or hydraulic water tunnels. A first set of studies on reduced scale models has been worked out according to a contract between French 'Meteorologie Nationale' and French 'Commissariat a l'Energie Atomique' and with the Collaboration of Saint-Cyr 'Institut Aerotechnique'. Essentially two kinds of results have been obtained: - The mathematical model of SUTTON for the turbulent diffusion in the atmosphere, deduced from the SUTTON theory, generally used by us, has been correctly verified, qualitatively and quantitatively whenever experiments were consistent with the theory conditions. - The quantitative assays of photographic and cinematographic visualization have given precise details on the phenomena inaccessible to calculations, due to the influence of obstacles and release conditions. - Generally, it can be asserted, that the atmospheric pollution studies are worked out by mock up experimentations and that, in some cases these experiments never can be replaced by mathematically pure models.

    The authors described the general principles governing the design of a laboratory for experimenting and handling radioactive substances. The difficulties encountered are of two types: 1) those due to the dangers of external irradiation; 2) those due to the dangers of internal contamination. As an example, the authors describe the French achievements in this field and in particular: - the high-activity laboratories at Saclay; - the laboratory for the examination of irradiated fuels at Saclay; - the 'hot' laboratory of the CEN-Grenoble; - the alpha, beta and gamma laboratories of the CEN-Fontenay-aux-Roses. Finally, the report describes the protective materials used for these installations.

    Full Text Available Une des caractéristiques majeures du Ferlo est l’aléa sur le plan pluviométrique, impactant négativement le remplissage correct des mares et rendant les sociétés pastorales plus vulnérables. Les politiques d’hydraulique pastorale, à travers une mauvaise gestion des forages n’ont permis d’y développer qu’un élevage extensif. De même, les politiques de maîtrise des eaux de surface ont contribué à La marginalisation de l’élevage dans la vallée alluviale du fleuve Sénégal. Dans CE contexte, l’Etat a aménagé quelques mares dans l’optique de mobiliser et valoriser les eaux de ruissellement, permettant ainsi d’amoindrir les contraintes du climat. Cette étude montre que les contraintes liées à l’accès et à l’aménagement de l’eau constituent un défi majeur au développement du Sahel sénégalais et qu’il est urgent de mettre en place un aménagement qui prenne en compte les différents types de points d’eau de la région.One of the major characteristics of the Ferlo zone is the rainfall vagary which affects negatively the correct filling of ponds and increases the vulnerability of pastoral societies. The pastoral hydraulic policies, in terms of bad management of drillings made it possible to develop only extensive livestock farming. In the same way, the policies of control of surface water contributed to the marginalization of the livestock farming in the Senegal river’s alluvial valley. In this context, the State created some ponds in order to mobilize and develop surface waters for the purpose of reducing climate constraints. This study shows that constraints on access, conservation and management of water resources constitute a major challenge to the development of the Senegalese Sahel. Therefore, it is urgent to implement an arrangement taking into account the different types of water points of the Ferlo zone.

    The Fassel method for analysis of bases in metals was used. By employing a smaller, completely cooled chamber greater sensitivity and lover blank values were obtained. A straight calibration curve, independent of the sample nature was established for oxygen using graphite pellets containing known amounts of ZnO and SnO{sub 2}. The calibration curve for hydrogen was obtained from previously analysed Zircaloy samples. In bath cases a lower limit of sensitivity of 15 {mu}g was attained.

  15. Variations in hydraulic conductivity with scale of measurement during aquifer tests in heterogeneous, porous carbonate rocks

    Science.gov (United States)

    Schulze-Makuch, Dirk; Cherkauer, Douglas S.

    Previous studies have shown that hydraulic conductivity of an aquifer seems to increase as the portion of the aquifer tested increases. To date, such studies have all relied on different methods to determine hydraulic conductivity at each scale of interest, which raises the possibility that the observed increase in hydraulic conductivity is due to the measurement method, not to the scale. This study analyzes hydraulic conductivity with respect to scale during individual aquifer tests in porous, heterogeneous carbonate rocks in southeastern Wisconsin, USA. Results from this study indicate that hydraulic conductivity generally increases during an individual test as the volume of aquifer impacted increases, and the rate of this increase is the same as the rate of increase determined by using different measurement methods. Thus, scale dependence of hydraulic conductivity during single tests does not depend on the method of measurement. This conclusion is supported by 22 of 26 aquifer tests conducted in porous-flow-dominated carbonate units within the aquifer. Instead, scale dependency is probably caused by heterogeneities within the aquifer, a conclusion supported by digital simulation. All of the observed types of hydraulic-conductivity variations with scale during individual aquifer tests can be explained by a conceptual model of a simple heterogeneous aquifer composed of high-conductivity zones within a low-conductivity matrix. Résumé Certaines études ont montré que la conductivité hydraulique d'un aquifère semble augmenter en même temps que la partie testée de l'aquifère s'étend. Jusqu'à présent, ces études ont toutes reposé sur des méthodes de détermination de la conductivité hydraulique différentes pour chaque niveau d'échelle, ce qui a conduit à penser que l'augmentation observée de la conductivité hydraulique pouvait être due aux méthodes de mesure et non à l'effet d'échelle.

    subterránea sucede en los primeros metros de la secuencia rocosa. A escala regional se puede aplicar la aproximación equivalente de medios porosos. Las medidas de la conductividad hidrálica fueron comparadas con la escala de las pruebas del acuífero, expresadas con el volumen investigado del acuífero. Se desarrolló un proceso de interpolación simple para la conductividad hidráulica de campo, con base en la distancia entre las medidas de campo y los volúmenes probados del acuífero. La distribución regional de la conductividad hidráulica, para las unidades acuíferas fracturadas mayores, indica que la dolomita es más permeable mientras que la arenisca y las rocas cristalinas son las unidades menos permeables. L'article présente les propriétés hydrauliques d'un aquifère régional rocheux qui ont été mesurées dans le cadre d'un projet concernant l'estimation de la ressource en eau de la plaine de St. Lawrence située dans la partie sud-ouest de Quebec. Affin de comprendre le comportement de l'aquifère tant à l'échelle de fracture qu'à l'échelle régionale on a mené des investigations hydrauliques en utilisant des essais differents. À l'échelle locale l'écoulement est déterminé en principal par le système des fractures. Les résultats des essais d'injection au niveau constant ont montré une tendence de décroissance de la conductivité hydraulique avec la profondeur ce qui indique que l'écoulement ait lieu en principal dans les premiers mètres de la structure rocheuse. À l'échelle règionale on peut appliquer l'approche de milieux poreux equivalent. Les mesures de conductivité hydraulique ont été corrélées avec l'échelle des essais de pompage exprimée en termes de volume investigué de l'aquifère. On a mis au point une méthode simple d'interpolation pour le champ de la conductivité hydraulique basée sur la distance entre les essais in situ et les volume investigués de l'aquifère. La distribution règionale de la conductivit

  9. Blackbody Radiation and the Carbon Particle

    Directory of Open Access Journals (Sweden)

    Pierre-Marie Robitaille

    2008-07-01

    Full Text Available Since the days of Kirchhoff, blackbody radiation has been considered to be a universal process, independent of the nature and shape of the emitter. Nonetheless, in promoting this concept, Kirchhoff did require, at the minimum, thermal equilibrium with an enclosure. Recently, the author stated (P.-M. Robitaille, IEEE Trans. Plasma Sci., 2003, v.31(6, 1263-1267; P.-M. Robitaille, Progr. in Phys., 2006, v.2, 22-23, that blackbody radiation is not universal and has called for a return to Stewart's law (P.-M. Robitaille, Progr. in Phys., 2008, v.3, 30-35. In this work, a historical analysis of thermal radiation is presented. It is demonstrated that soot, or lampblack, was the standard for blackbody experiments throughout the 1800s. Furthermore, graphite and carbon black continue to play a central role in the construction of blackbody cavities. The advent of universality is reviewed through the writings of Pierre Prevost, Pierre Louis Dulong, Alexis Therese Petit, Jean Baptiste Joseph Fourier, Simeon Denis Poisson, Frederick Herve de la Provostaye, Paul Quentin Desain, Balfour Stewart, Gustav Robert Kirchhoff, and Max Karl Ernst Ludwig Planck. These writings illustrate that blackbody radiation, as experimentally produced in cavities and as discussed theoretically, has remained dependent on thermal equilibrium with at least the smallest carbon particle. Finally, Planck's treatment of Kirchhoff's law is examined in detail and the shortcomings of his derivation are outlined. It is shown once again, that universality does not exist. Only Stewart's law of thermal emission, not Kirchhoff's, is fully valid.

    The present report gives an overview of the present facilities of energy productions in France and their perspectives. the electric production comes for half about power stations hydraulics and for half of thermal power stations. However due to the increase of the energy consumption, France is particularly interested by the atomic energy that appears to bring a supply in due time to the hydraulics and to limit a development of the thermal power stations to which the natural resources of France in classic fuel would not permit to cope presumably. The integration of the nuclear plants to the other production facilities will make itself gradually according to the evolution of the energy needs. (M.B.) [French] Le present rapport donne un apercu des moyens actuels de productions energetiques en France et de ses perspectives. la production electrique provient pour moitie environ de centrales hydraulique et pour moitie de centrales thermiques. Cependant face a l'augmentation de la consommation energetique, la France est tres particulierement interessee par l'energie atomique qui parait devoir apporter en temps utile la releve a l'hydraulique et limiter un developpement des centrales thermiques auxquels les ressources naturelles de la France en combustible classique ne permettraient vraisemblablement pas de faire face. L'integration des centrales nucleaires aux autres moyens de production se fera graduellment en fonction de l'evolution des besoins energetiques. (M.B.)

    Deteriorating groundwater quality, as represented by high nitrates, in the Colline province of Benin, West Africa was identified by the Benin national water agency, Direction Hydraulique. For unknown reasons the Colline province had consistently higher nitrate levels than any other region of the country. In an effort to address this water quality issue, a collaborative team was created that incorporated professionals from the Universite d'Abomey-Calavi (Benin), the University of Notre Dame (USA), Direction l'Hydraulique (a government water agency in Benin), Centre Afrika Obota (an educational NGO in Benin), and the local population of the village of Adourekoman. The goals of the project were to: (i) identify the source of nitrates, (ii) test field techniques for long term, local monitoring, and (iii) identify possible solutions to the high levels of groundwater nitrates. In order to accomplish these goals, the following methods were utilized: regional sampling of groundwater quality, field methods that allowed the local population to regularly monitor village groundwater quality, isotopic analysis, and sociological methods of surveys, focus groups, and observations. It is through the combination of these multi-disciplinary methods that all three goals were successfully addressed leading to preliminary identification of the sources of nitrates in the village of Adourekoman, confirmation of utility of field techniques, and initial assessment of possible solutions to the contamination problem.

    The aim of this work was to evaluate the effects of the supplementation of two extra-virgin olive oils (EVOO) having different polyphenols content, on canine spermatozoa kinetic parameters and seminal plasma oxidative status. The study was conducted on 12 clinically healthy dogs of different breeds (2-7 years, 5-48 kg of body weight) divided into two groups: an experimental group supplemented with EVOO (Coratina cultivar) high in polyphenols (H-P) and a control group fed EVOO (Cima di Bitonto cultivar) low in polyphenols (L-P). The oil was daily administered per os (1 ml/3 kg BW) before meal. Semen collection was made twice at 15 days distance (D0 1 and D0 2 ) and then at 30 (D30), 60 (D60) and 90 (D90) days. Semen concentration and kinetic parameters were measured using computer-assisted sperm analysis (CASA) system to evaluate: sperm total count, sperm motile (MOT%), progressive motility (PROGR%) and its fractions, straight-line velocity (VSL, μm/s), curvilinear velocity (VCL, μm/s), average path velocity (VAP, μm/s), amplitude of lateral head displacement (ALH, μm), beat cross frequency (BCF, Hz), straightness (STR%) and linearity (LIN%). On seminal plasma, reactive oxygen species (ROS) and biological antioxidant potential (BAP) were tested. From findings, no differences were found for sperm MOT, VSL, VCL, VAP, ALH, BCF, STR, LIN and BAP. A gradual enhancement of PROGR% was observed in H-P group (p group (p < .05). In conclusion, our results highlight the positive effects of EVOO polyphenols on sperm PROGR% in healthy dogs. © 2018 Blackwell Verlag GmbH.

    In piles cooled by pressurized carbon dioxide, type G{sub 3}, the chief radioactivity of the gas is that of nitrogen - 16 created by {sup 16}O (n, p) {sup 16}N reaction of the fact neutrons on the oxygen. This activity short-lived and with a high {beta} energy, masks the activity of fission gases escaping through a crack in the canning into the carbon dioxide, and makes it necessary to use a material method to separate the solid fission products before the detection proper. This detection is carried out by means of a special electronic system whose input is a scintillator associated with a photomultiplier. A system for measuring the evolution of a crack with compensation for power variations allows the speed of development of a crack to be followed. This instrument, baptised 'evolution-meter', is designed to make the measurement of the activity of the cooling gas in the canals by a zero method, and thus to be independent of: 1) the activity of the gas itself, left after discrimination of the fission products; 2) uranium pollution of the canning and eventual pollution of the canals after rapid splits in the canning. The 'evolution-meter' consists of a memory which stores canal activity values taken at a given moment considered as a reference. The values of canal activity during the course of prospection are compared to this memory. A difference between the values indicates the appearance or the evolution of a crack in the canning. To account for the variations of thermodynamic running conditions in the canals, the values taken from the memory are corrected by a signal from an activity detector placed in the general circuit of gas leaving the pile. In the case of the pile EL{sub 2}, also cooled by pressurized CO{sub 2}, a method similar to that of G{sub 3}, has been used. Samples of cooling gas are taken successively in each of the 133 pile cells by the opening of electro-valves. The gas is filtered and the fission products extracted by an electrostatic collecting method. A scintillator and an electronic system provide a specific signal of the fission products which is then marked on a recorder. In a case where the activity threshold is exceeded, the cell involved is isolated from the prospection system and taker, over by a 'follow-up' detector which follows the evolution of the crack. A year of working on the pile G{sub 1}, which is cooled by air at atmospheric pressure, has made it possible to obtain results on the operation of the canning-burst detection appliance, which has led us to perfect the original device by installing an 'evolution-meter' of the type described above for G{sub 3}. The reactor EL{sub 3}, cooled by heavy water, uses a detection system based on the measurement by GM counters of the activity of the fission gases carried by diluted helium into the heavy water, then extracted by hydro-cyclones. The selectivity of the system gives it a low sensitivity to parasite activities, and an excellent performance. (author) [French] Dans les piles refroidies par gaz carbonique sous pression, du type G{sub 3}, la radioactivite principale du gaz est celle de l'azote 16 creee par reaction {sup 16}O(n, p) {sup 16}N des neutrons rapides sur l'oxygene. Cette activite, de vie courte et de forte energie {beta}, masque l'activite des gaz de fission s'echappant par une fissure de gaine dans le gaz carbonique et oblige a utiliser une methode de separation materielle des produits de fission solides avant la detection proprement dite. Cette detection est faite par une chaine electronique speciale dont l'entree est un scintillateur associe a un photomultiplicateur. Un systeme de mesure d'evolution de fissure avec compensation des variations de puissance permet de suivre la vitesse d'evolution d'une fissure. Cet appareil, baptise evolumetre, est destine a ramener a une methode de zero la mesure de l'activite du gaz de refroidissement des canaux, il permet de s'affranchir: 1) de l'activite propre du gaz restant apres la discrimination des produits de fission, 2) de la pollution d'uranium des gaines et de la pollution eventuelle des canaux apres ruptures de gaines rapides. L'evolumetre est constitue par une memoire qui stocke les valeurs de l'activite des canaux prises a un instant considere comme reference. A cette memoire, on vient comparer les valeurs de l'activite des canaux en cours de prospection. Une difference entre ces valeurs indique l'apparition ou l'evolution d'une fissure de gaine. Pour tenir compte des variations du regime thermodynamique dans les canaux, les valeurs extraites de la memoire sont corrigees par un signal provenant d'un detecteur d'activite place dans le circuit general de sortie du gaz de la pile. Dans le cas de la pile EL{sub 2}, egalement a refroidissement par CO{sub 2}, sous pression, une methode analogue a celle de G{sub 3} a ete utilisee. Des echantillons de gaz de refroidissement sont preleves dans chacune des 133 cellules de la pile successivement par l'ouverture d'electrovannes. Le gaz est filtre et les produits de fission sont extraits par une methode de collection electrostatique. Un scintillateur et une chaine electronique fournissent un signal specifique des produits de fission qui s'inscrit sur un enregistreur. Dans le cas d'un depassement du seuil d'activite, la cellule incriminee est isolee du systeme de prospection et prise en charge par un detecteur 'suiveur' qui permet de suivre l'evolution de la fissure. Une annee d'exploitation de la pile G1 qui est refroidie a l'air a la pression atmospherique a permis d'obtenir des resultats sur le fonctionnement du dispositif D.R.G. ce qui nous a amenes a perfectionner le dispositif initial en installant un evolumetre du type decrit ci-dessus pour G{sub 3}. Le reacteur EL{sub 3}, refroidi a l'eau lourde, utilise un systeme de detection base sur la mesure, au moyen de compteurs G.M., de l'activite des gaz de fission entraines par de l'helium dilue dans l'eau lourde puis extraits de celle-ci par des hydrocyclones. La selectivite du systeme lui confere une bonne insensibilite aux activites parasites et d'excellentes performances. (auteur)

  13. Aspects récents de la thermodynamique des solutions de polymères Recent Aspects of the Thermodynamics of Polymer Solutions

    Directory of Open Access Journals (Sweden)

    Dayantis J.

    2006-11-01

    Full Text Available On examine dans cet article différentes approches de la thermodynamique des solutions de polymères placées dans leur contexte historique. On rappelle d'abord le modèle du réseau de Flory-Huggins et on en souligne les déficiences. On traite ensuite brièvement de la mécanique statistique des solutions de polymères introduite par Prigogine en 1957 et on montre qu'elle constitue un progrès qualitatif par rapport à la théorie du réseau, mais qu'elle ne prévoit cependant pas de manière quantitative les propriétés de ces solutions. On montre ensuite que le concept de volume libre, qui permet un traitement simplifié de certaines quantités, permet également d'expliquer tout naturellement l'existence d'une deuxième température de séparation en phase lorsque l'on élève la température, propriété qui différencie les solutions de polymères des mélanges de liquidés simples. Enfin, dans une dernière partie, on mentionne brièvement les travaux récents de l'École de Paris, qui traite les solutions de polymères par analogie avec les transitions magnétiques. This article examines différent approaches ta the thermodynamics of polymer solutions set in their historical context. First of all, the Flory-Huggins network model is described and ifs deficiencies are pointed out. Then attention is briefly drawn to the statistical mechanics of polymer solutions as introduced by Prigogine in 1957, and this mechanics is shown to be a qualitative advance compared with the network theory, but it nonetheless does not quantitatively predict the properties of such solutions. It is then shown that the concept of free volume, enabling some quantifies to be treated in a simplified way, also serves to provide a quite natural explanation for the existence of a second phase separation temperature when the temperature is raised, i. e. a property that differentiates polymer solutions from simple liquid mixtures. In the final part, brief mention is made

    Ramavataram, S.

    1991-01-01

    In support of a continuing program of systematic evaluation of nuclear structure data, the National Nuclear Data Center maintains a complete computer file of references to the nuclear physics literature. Each reference is tagged by a keyword string, which indicates the kinds of data contained in the article. This master file of Nuclear Structure References (NSR) contains complete keyword indexes to literature published since 1969, with partial indexing of older references. Any reader who finds errors in the keyword descriptions is urged to report them to the National Nuclear Data Center so that the master NSR file can be corrected. In 1966, the first collection of Recent References was published as a separate issue of Nuclear Data Sheets. Every four months since 1970, a similar indexed bibliography to new nuclear experiments has been prepared from additions to the NSR file and published. Beginning in 1978, Recent References was cumulated annually, with the third issue completely superseding the two issues previously published during a given year. Due to publication policy changes, cumulation of Recent Reference was discontinued in 1986. The volume and issue number of all the cumulative issues published to date are given. NNDC will continue to respond to individual requests for special bibliographies on nuclear physics topics, in addition to those easily obtained from Recent References. If the required information is available from the keyword string, a reference list can be prepared automatically from the computer files. This service can be provided on request, in exchange for the timely communication of new nuclear physics results (e.g., preprints). A current copy of the NSR file may also be obtained in a standard format on magnetic tape from NNDC. Requests for special searches of the NSR file may also be directed to the National Nuclear Data Center

  5. The Liquid Metallic Hydrogen Model of the Sun and the Solar Atmosphere I. Continuous Emission and Condensed Matter Within the Chromosphere

    Directory of Open Access Journals (Sweden)

    Robitaille P.-M.

    2013-07-01

    Full Text Available The continuous spectrum of the solar photosphere stands as the paramount observation with regard to the condensed nature of the solar body. Studies relative to Kirchhoff’s law of thermal emission (e.g. Robitaille P.-M. Kirchhoff’s law of thermal emission: 150 years. Progr. Phys., 2009, v. 4, 3–13. and a detailed analysis of the stellar opacity problem (Robitaille P.M. Stellar opacity: The Achilles’ heel of the gaseous Sun. Progr. Phys., 2011, v. 3, 93–99 have revealed that gaseous models remain unable to properly account for the generation of this spectrum. Therefore, it can be stated with certainty that the photosphere is comprised of condensed matter. Beyond the solar surface, the chromospheric layer of the Sun also generates a weak continuous spectrum in the visible region. This emission exposes the presence of material in the condensed state. As a result, above the level of the photosphere, matter exists in both gaseous and condensed forms, much like within the atmosphere of the Earth. The continuous visible spectrum associated with the chromosphere provides the twenty-sixth line of evidence that the Sun is condensed matter.

    The influence of recent immobilization or surgery on mortality in patients with pulmonary embolism (PE) is not well known. We used the Registro Informatizado de Enfermedad TromboEmbólica (RIETE) data to compare the 3-month mortality rate in patients with PE, with patients categorized according to the presence of recent immobilization, recent surgery, or neither. Of 18,028 patients with PE, 4169 (23%) had recent immobilization, 2212 (12%) had recent surgery, and 11,647 (65%) had neither. The all-cause mortality was 10.0% (95% confidence interval [CI] 9.5-10.4), and the PE-related mortality was 2.6% (95% CI 2.4-2.9). One in every two patients who died from PE had recent immobilization (43%) or recent surgery (6.7%). Only 25% of patients with immobilization had received prophylaxis, as compared with 65% of the surgical patients. Fatal PE was more common in patients with recent immobilization (4.9%; 95% CI 4.3-5.6) than in those with surgery (1.4%; 95% CI 1.0-2.0) or those with neither (2.1%; 95% CI 1.8-2.3). On multivariate analysis, patients with immobilization were at increased risk for fatal PE (odds ratio 2.2; 95% CI 1.8-2.7), with no differences being seen between patients immobilized in hospital or in the community. Forty-three per cent of patients dying from PE had recent immobilization for ≥4 days. Many of these deaths could have been prevented. © 2012 International Society on Thrombosis and Haemostasis.

    1963-11-15

    Now that several UO{sub 2}-fuelled reactors are operating routinely, good irradiation performance of UO{sub 2} is taken for granted. It is therefore stimulating to find that significant developments are still occurring. Most exciting was the recent discovery by Battelle Memorial Institute workers that a particular single crystal of UO{sub 2} had a very high thermal conductivity at elevated temperatures. Following controversy over the matter, an irradiation at Chalk River demonstrated that the large grains formed in operating fuel elements do not necessarily exhibit this enhanced conductivity. Our laboratory experiments have shown that the enhancement is only present in hypostoichiometric compositions and depends little, if any, on the absence of grain boundaries. Indeed, the high conductivity can be obtained in polycrystalline sinters by controlling the stoichiometry. It has long been known that sheath elongation could be reduced by fabricating the UO{sub 2} pellets with depressions in their end faces. Later it was shown that movement of the fuel into a void at the end of the pellet stack was impeded by diametral expansion of the fuel and its mechanical interaction with the sheath. The biggest advance in minimizing sheath distensions has been the realization that longitudinal and diametral expansions are interrelated through the volume expansion of the fuel whose hot core is appreciably plastic. Our empirical knowledge of the factors determining the release of fission-product gases from UO{sub 2} has improved. In particular, increasing the irradiation exposure from 10{sup 15} to 10{sup 18} fissions/cm{sup 3} can reduce the apparent diffusion rates for xenon in UO{sub 2} during subsequent anneals by a factor of 10{sup 3}. The gas is probably immobilized in minute traps, some existing in the original material and some generated by irradiation damage. Detailed analysis indicated slow escape from the traps, presumably from the finite solubility of the xenon in UO{sub 2

  14. Capture-zone design in an aquifer influenced by cyclic fluctuations in hydraulic gradients

    Science.gov (United States)

    Zawadzki, Willy; Chorley, Don; Patrick, Guy

    2002-10-01

    Design of a groundwater pumping and treatment system for a wood-treatment facility adjacent to the tidally influenced Fraser River estuary required the development of methodologies to account for cyclic variations in hydraulic gradients. Design of such systems must consider the effects of these cyclic fluctuations on the capture of dissolved-phase contaminants. When the period of the cyclic fluctuation is much less than the travel time of the dissolved contaminant from the source to the discharge point, the hydraulic-gradient variations resulting from these cycles can be ignored. Capture zones are then designed based on the average hydraulic gradient determined using filter techniques on continuous groundwater-level measurements. When the period of cyclic fluctuation in hydraulic gradient is near to or greater than the contaminant travel time, the resulting hydraulic-gradient variations cannot be ignored. In these instances, procedures are developed to account for these fluctuations in the capture-zone design. These include proper characterization of the groundwater regime, assessment of the average travel time and period of the cyclic fluctuations, and numerical techniques which allow accounting for the cyclic fluctuations in the design of the capture zone. Résumé. L'étude d'un système de pompage et de traitement de l'eau souterraine d'une usine de traitement du bois proche de l'estuaire de la rivière Fraser, influencé par les marées, a nécessité la mise au point de méthodologies pour prendre en compte les variations cycliques de gradients hydrauliques. L'étude de tels systèmes doit considérer les effets de ces variations cycliques sur l'extraction des contaminants en phase dissoute. Lorsque la période des variations cycliques est très inférieure au temps de parcours du contaminant dissous entre la source et le point d'émergence, les variations du gradient hydraulique résultant de ces cycles peuvent être ignorées.

    Major depressive disorder (MDD) is associated with suicide. Although several studies have reported its association with low serum lipid, few studies have investigated relationships between current suicidality and lipid profiles, comparing with other blood measures in MDD patients. The study population consisted of 555 subjects with MDD who were ≥ 18 years old, evaluated by the Mini International Neuropsychiatric Interview (MINI) with the suicidality module. At the evaluation visit, we measured serum lipid profiles including total cholesterol, triglycerides (TG), low-density lipoprotein (LDL), high-density lipoprotein (HDL), and very low-density lipoprotein (VLDL), and blood measures such as fasting glucose, total protein, albumin, blood urea nitrogen, creatinine, thyroid hormones, red and white blood cells, platelet count, hemoglobin, and hematocrit. Recent attempters who had attempted suicide within the past month showed significantly lower TG and higher HDL levels than lifetime and never attempters, using Tukey's post-hoc analysis. Recent attempters exhibited lower TG and higher HDL than those with recent suicide ideation and wish to self-harm and those without previous attempt. Linear regression analysis revealed that TG was negatively associated with current suicidality scores (β = -0.187, p = 0.039), whereas VLDL was positively associated with the recent suicide status (β = 0.198, p = 0.032) after controlling for age and sex. There were no significant differences between the groups in terms of other serum lipid profiles and blood measures. Low serum TG, high HDL and VLDL levels are associated with recent suicide attempt or recent suicide status in patients with MDD. Copyright © 2014 Elsevier Inc. All rights reserved.

  17. Photoimmunology: recent data

    1990-01-01

    The immunologic consequences of exposure of skin to ultraviolet radiations (UV) have recently been addressed by a great number of studies in humans and laboratory animals. This article reviews our current understanding of photoimmunology, i.e. of both photocarcinogenesis and the mechanisms of photoimmunosuppression. Recent studies have shown that UV-induced tumors are highly antigenic because of the expression of a tumor-specific antigen. Moreover, they express a common, UV-induced antigen that activates suppressor T cells, explaining why they are tolerated by UV-irradiated animals. In addition to being carcinogenic, UV radiation inhibits delayed and contact hypersensitivity reactions by a variety of mechanisms, which depend on the radiation dose and on the mode of administration of the antigen. UV-induced alterations of antigen-presenting cells and the release of soluble mediators by keratinocytes are responsible for activation of suppressor T-cells resulting in immunosuppression [fr

    internal can of the annular element, has necessitated very much research work. - the exact temperature drop at the contact between the uranium and the can, and the strength of the lower end of the cartridge are points which are increasingly crucial in the case of the annular element. All in all the annular element thus calls for a great research effort. This effort is justified by the big step forwards in which it will result in the case of the EDF reactors thanks to its high specific power and to the high weight of uranium in each cartridge. (authors) [French] La politique choisie en France pour le developpement des elements combustibles destines aux reacteurs de l'Electricite de France, consiste a chercher, pour chaque pile nouvelle, a beneficier au maximum des progres techniques les plus recents en etudiant chaque fois un nouvel element combustible permettant une puissance par canal aussi elevee que possible. Les derniers elements combustibles ainsi etudies par le Commissariat a l'Energie Atomique sont de deux types differents: un element a tube d'uranium ferme aux deux extremites et refroidi exterieurement (ce type d'element, retenu pour les reacteurs EDF 2, EDF 3 et EDF 4 permet des puissances specifiques maximum de l'ordre de 6 MW/t). Un element a tube d'uranium ouvert, refroidi interieurement et exterieurement, appele clemont annulaire et dont on etudie la possibilite pour EDF5. Un tel element peut permettre des puissances specifiques superieures a 12 MW/t. Ces deux types d'elements possedent des caracteristiques communes: la gaine, pour le refroidissement externe, comporte des ailettes en chevron. Ce type de profil, qui a recu recemment des ameliorations notables augmentant son efficacite thermique, a l'avantage important d'eviter les vibrations de cartouche mais a pose des problemes technologiques de tenue au cyclage thermique qui ont necessite une etude approfondie. les cartouches sont placees a l'interieur de chemise en graphite, ce qui limite les efforts

    Aitken, M.J.

    1984-01-01

    Initially the application of thermoluminescent dating was to ancient pottery and other baked clay, the detection of forgeries in art ceramics having a particularly powerful impact. In recent years there has been a growing extension of TL into non-pottery materials. Heated flints from paleolithic fire-places is one application. Another is in the dating of igneous rocks from recent volcanic events; formerly this had been impossible on account of the malign phenomenon of non-thermal ('anomalous') fading exhibited by volcanic minerals but this is now being circumvented by utilising TL in the 600 0 C region of the glow curve. TL dating has also been extended to unburnt calcite, one application being stalagmitic floors in paleolithic caves. Another recent development is the use of TL for dating aeolian sediment and some types of waterborne sediment. These developments give prospect of establishing a TL-based chronology, both for archaeology and quaternary research, extending back well beyond the range of radiocarbon, perhaps reaching a million years ago.

  15. Craniofacial Secular Change in Recent Mexican Migrants.

    Science.gov (United States)

    2016-01-01

    Research by economists suggests that recent Mexican migrants are better educated and have higher socioeconomic status (SES) than previous migrants. Because factors associated with higher SES and improved education can lead to positive secular changes in overall body form, secular changes in the craniofacial complex were analyzed within a recent migrant group from Mexico. The Mexican group represents individuals in the act of migration, not yet influenced by the American environment, and thus can serve as a starting point for future studies of secular change in this population group. The excavation of a historic Hispanic cemetery in Tucson, Arizona, also allows for a comparison between historic Hispanics and recent migrants to explore craniofacial trends over a broad time period, as both groups originate from Mexico. The present research addresses two main questions: (1) Are cranial secular changes evident in recent Mexican migrants? (2) Are historic Hispanics and recent Mexican migrants similar? By studying secular changes within a migrant population group, secular trends may be detected, which will be important for understanding the biological variation of the migrants themselves and will serve as a preliminary investigation of secular change within Mexican migrants. The comparison of a sample of recent Mexican migrants with a historic Hispanic sample, predominantly of Mexican origin, allows us to explore morphological similarities and differences between early and recent Mexicans within the United States. Vault and face size and a total of 82 craniofacial interlandmark distances were used to explore secular changes within the recent Mexican migrants (females, n = 38; males, n = 178) and to explore the morphological similarities between historic Hispanics (females, n = 54; males, n = 58) and recent migrants. Sexes were separated, and multivariate adaptive regression splines and basis splines (quadratic with one knot) were used to assess the direction and magnitude

  16. Recent Transmission of Tuberculosis - United States, 2011-2014.

    Directory of Open Access Journals (Sweden)

    Courtney M Yuen

    Full Text Available Tuberculosis is an infectious disease that may result from recent transmission or from an infection acquired many years in the past; there is no diagnostic test to distinguish the two causes. Cases resulting from recent transmission are particularly concerning from a public health standpoint. To describe recent tuberculosis transmission in the United States, we used a field-validated plausible source-case method to estimate cases likely resulting from recent transmission during January 2011-September 2014. We classified cases as resulting from either limited or extensive recent transmission based on transmission cluster size. We used logistic regression to analyze patient characteristics associated with recent transmission. Of 26,586 genotyped cases, 14% were attributable to recent transmission, 39% of which were attributable to extensive recent transmission. The burden of cases attributed to recent transmission was geographically heterogeneous and poorly predicted by tuberculosis incidence. Extensive recent transmission was positively associated with American Indian/Alaska Native (adjusted prevalence ratio [aPR] = 3.6 (95% confidence interval [CI] 2.9-4.4, Native Hawaiian/Pacific Islander (aPR = 3.2, 95% CI 2.3-4.5, and black (aPR = 3.0, 95% CI 2.6-3.5 race, and homelessness (aPR = 2.3, 95% CI 2.0-2.5. Extensive recent transmission was negatively associated with foreign birth (aPR = 0.2, 95% CI 0.2-0.2. Tuberculosis control efforts should prioritize reducing transmission among higher-risk populations.

    Full Text Available The continuous innovations in technology, instrumentations, and techniques allow urologists to perform percutaneous nephrolithotomy (PCNL with increasing efficacy. Although recent advances have facilitated the procedure, some steps are still challenging. A thorough review of the recent urologic literature was performed to identify these improvements in PCNL technique. The newer developments mainly focused on multimodal imaging techniques, miniaturisation of instruments, tracking and navigation systems during access to the stone, and robotic systems. Further studies are necessary to better define the benefits of these new fruitful developments which remain an active research field.

    Nowadays there is growing interest by the food industry, government and consumers in the use of food irradiatin to kill harmful insects, prevent diseases and keep food fresher longer. This interest has been stimulated by growing public concern over chemicals used in foods. While food irradiation technologies have been around for more than 50 years, only recently have they become cost effective and gained prominent attention as potentially safer ways of protecting food products and public health. This paper looks at recent developments in food irradiation processing and discusses the issues that lie ahead. (author)

    Full Text Available In this study the author examines the development and the impact of the strong sexual repression which settled in the heart of the Western Civilization around the middle of the XVI century and which really loosened only starting from the 1960’s. Within the founding tension between the libido of the person and the collective ideals, this process constantly developed during this long period, creating a strong effort of sublimation, under the different successive cultural expressions in relation to the religion, Enlightenment, medicine of the XIX century and the capitalist market. From 1960 to our days, a new approach to the Western sexuality has been developed, testifying about the profound cultural and societal movements.

    Computerized gas chromatography-mass spectrometry (GC-MS) is now an essential tool in the analysis of the complex mixtures of lipids (geolipids) encountered in aquatic sediments, both 'recent' (less than 1 million years old) and ancient. The application of MS, and particularly GC-MS, has been instrumental in the rapid development of organic geochemistry and environmental organic chemistry in recent years. The techniques used have resulted in the identification of numerous compounds of a variety of types in sediments. Most attention has been concentrated on molecules of limited size, mainly below 500 molecular mass, and of limited functionality, for examples, hydrocarbons, fatty acids and alcohols. Examples from recent studies (at Bristol) of contemporary, 'recent' and ancient sediments are presented and discussed.

    The current trend towards establishing the national programme on food irradiation appears to be maturing with great interest in fundamental and practical problems. Efforts of the Atomic Energy Commission to devise a programme on development studies, and their practical application, which will probably commence in 1967, are now being made. The collaboration of researchers in this field has resulted in the setting-up of the Japanese Research Association. for Food Irradiation. This organization is expected to play an important role in promoting the national programme. At present there are in Japan about 30 kCi-scale sources of radioisotopes, and almost the same number of electron generators, including some pilot-scale irradiation facilities. Practical studies on food irradiation in Japan are classified into three categories, in terms of their purpose. The first is radiation preservation, to which major efforts have been devoted. Sprout inhibition of potatoes, onions and sweet potatoes, disinfestation of rice, wheat and their products, low-dose treatment of vacuum-sealed fish and shell-fish with doses of less than 0.5 Mrad, and of some fruits, such as strawberry and orange, are the examples which are considered to be potential subjects for radiation treatment. The first interesting observation was in rice irradiation where, at 5000 to 20 000 rad disinfestation dose, quality changes detectable immediately after irradiation became insignificant after eight months' storage according to the statistical analysis of organoleptic data. The second was in connection with studies on the elimination of harmful biological and biochemical factors in foods from the viewpoint of public health. Radiation sensitivity of the toxin produced by Cl. botulinum, Type E| was investigated in studying the wholesomeness of irradiated foods. The third was concerned with the utilization of the chemical effect of radiation. For example, studies were made of the irradiation of marine algae with 0.5 to 0.7 Mrad to improve quality and the yield of extracted agar and the radiation acceleration of the ageing of alcoholic beverages, particularly distilled liquors, with doses of up to 0.5 Mrad. Besides these practical investigations, extensive work has been conducted with the fundamental aspects, including the radiosensitization of microorganisms, enzyme inactivation by radiation, and other subjects in radiation chemistry associated with food irradiation. (author) [French] Actuellement, l'organisation du programme national d'irradiation de produits alimentaires semble se preciser, l'interet se portant a la fois sur les problemes fondamentaux et les questions pratiques. La Commission de l'energie atomique s'occupe activement d'elaborer le programme d'etudes et de realisations qui sera mis en oeuvre vraisemblablement en 1967. La collaboration des chercheurs dans ce domaine a abouti a la creation de l'Association japonaise de recherches sur l'irradiation des denrees alimentaires, organisme qui est appele a jouer un role important dans le developpement du programme national. Le Japon dispose actuellement de quelque 30 sources de radioisotopes de l'ordre du kCi et d'autant de generateurs d'electrons, y compris quelques installations experimentales. Les etudes pratiques sur l'irradiation de denrees alimentaires au Japon sont orientees dans trois directions. Premierement, la radioconservation, qui beneficie de l'effort principal. L'inhibition de la germination des pommes de terre, des oignons et des patates, la desinsection du riz, du ble et de leurs derives, et le traitement a faible dose (moins de 0,5 Mrad) en emballages sous vide du poisson et des crustaces et mollusques ainsi que de quelques fruits tels que la fraise et l'orange sont autant d'exemples des possibilites d'utilisation des rayonnements. L'irradiation du riz a permis de faire une observation interessante, a savoir qu'a la suite d'une irradiation de desinsection a des doses comprises entre 5000 et 20 000 rad, les modifications de qualite decelables immediatement apres l'irradiation se sont revelees insignifiantes apres huit mois de conservation d'apres l'analyse statistique des donnees organoleptiques. Deuxiemement, etude de l'elimination des agents biologiques et biochimiques nuisibles dans les produits, du point de vue de la sante publique. La sensibilite aux rayonnements de la toxine produite par Cl. botulinum E a ete etudiee en rapport avec l'innocuite des produits irradies. Troisiemement, l'utilisation des effets chimiques des rayonnements. On a etudie par exemple l'irradiation d'algues marines a des doses de 0,5 a 0,7 Mrad en vue d'ameliorer la qualite et la quantite de la gelose extraite, ainsi que l'acceleration, par des doses de rayonnement atteignant 0,5 Mrad, du vieillissement des boissons alcooliques, notamment des liqueurs distillees. Outre ces etudes de caractere pratique, on s'est occupe activement des problemes fondamentaux comprenant la radiosensibilisation des micro-organismes, l'inactivation des enzymes par les rayonnements et d'autres questions de radiochimie interessant l'irradiation des denrees alimentaires. (author) [Spanish] En la actualidad parecen perfilarse los planes para establecer en el Japon un programa nacional de irradiacion de alimentos orientado hacia los problemas fundamentales y practicos. La Comision de Energia Atomica ha comenzado ya a preparar el programa de estudios fundamentales y sus aplicaciones, que se emprendera probablemente en 1967. Gracias a la colaboracion de especialistas se ha constituido la Sociedad japonesa de investigaciones sobre irradiacion de alimentos; se espera que esta organizacion desempene una labor importante en la ejecucion del programa nacional. En la actualidad, el Japon dispone de unas 30 fuentes radioisotopicas del orden del kilocurie, y casi del mismo numero de generadores de electrones, incluidas varias plantas piloto de irradiacion. En el Japon los estudios practicos sobre irradiacion de alimentos se clasifican en tres.categorias, segun la finalidad. La primera comprende los estudios sobre conservacion, a los que se dedican los mayores esfuerzos. Entre las aplicaciones interesantes de las radiaciones que cabe mencionar figura la inhibicion de la germinacion de patatas, cebollas y batatas, la desinfestacion de arroz, trigo y sus derivados, el tratamiento-en dosis ligeras (inferiores a 0,5 Mrad) de pescado y mariscos envasados al vacio, asi como de algunas frutas, tales como fresas y naranjas. Una observacion interesante, en lo que se refiere a la irradiacion del arroz en dosis de 5000 a 20 000 rad para desinfestarlo, es que los cambios de calidad apreciables inmediatamente despues de la irradiacion resultaron insignificantes en el analisis estadistico de datos organolepticos efectuado al cabo de ocho meses de almacenamiento. La segunda categoria comprende los estudios sobre eliminacion de agentes nocivos (biologicos y bioquimicos) de los alimentos desde el punto de vista sanitario. Se ha investigado, en relacion con la comestibilidad de los alimentos irradiados, la sensibilidad a la irradiacion de la toxina producida por el Cl. botulinum tipo E. La tercera categoria comprende los estudios referentes al aprovechamiento de los efectos quimicos de las radiaciones. Cabe citar, como ejemplo, la irradiacion de algas marinas con dosis de 0,5 a 0,7 Mrad para mejorar la calidad y rendimiento del agar extraido, y la aceleracion por irradiacion del envejecimiento de bebidas alcoholicas, sobre todo de licores destilados, con dosis no superiores a 0,5 Mrad. Ademas de estas investigaciones practicas se han realizado amplios estudios sobre algunos aspectos fundamentales: radiosensibilizacion de microorganismos, inactivacion de enzimas por irradiacion y'otras cuestiones de radioquimica referentes a la irradiacion de alimentos. (author) [Russian] V nastojashhee vremja, kak predstavljaetsja, sushhestvuet bol'shoj interes i vyrisovyvaetsja tendencija v otnoshenii vyrabotki nacional'noj programmy po oblucheniju produktov pitanija v oblasti kak fundamental'nyh, tak i prakticheskih problem.

Sotrudnichestvo issledovatelej v jetoj oblasti privelo k sozdaniju Japonskoj issledovatel'skoj associacii po oblucheniju produktov pitanija, i jeta organizacija, kak ozhidaetsja, budet igrat' vazhnuju rol' v razrabotke nacional'noj programmy. V nastojashhee vremja v Japonii imeetsja okolo 30 radioizotopnyh istochnikov porjadka kilokjuri i pochti takoe zhe chislo generatorov jelektronov, vkljuchaja neskol'ko krupnyh obluchajushhih ustanovok. Prakticheskie issledovanija po oblucheniju produktov v Japonii razdeljajutsja na tri kategorii v zavisimosti ot ih celi. Pervaja - jeto predohranenie produktov pitanija ot.porchi s pomoshh'ju obluchenija; jetim issledovanijam udeljaetsja glavnoe vnimanie. Zaderzhka prorastanija kartofelja, luka i batata, obezzarazhivanija risa, pshenicy i izdelij iz nih i obrabotka nebol'shimi dozami germeticheski upakovannoj ryby i vodnyh zhivotnyh, imejushhih pancir', pri velichine dozy menee 0,5 Mrad i nekotoryh fruktov, takih kak klubnika i apel'siny, - jeto primery potencial'nogo primenenija obluchenija. Interesnoe nabljudenie pri obluchenii risa sostojalo v tom, chto pri obezzarazhivajushhej doze v 5 000- 20 000 rad kachestvennye izmenenija, obnaruzhimye neposredstvenno posle obluchenija, stali posle vos'mimesjachnogo hranenija neznachitel'nymi pri statisticheskom analize organolepticheskih dannyh. Vtoraja kategorija - jeto issledovanija po ocenke vrednyh biologicheskih i biohimicheskih faktorov v produktah pitanija s tochki zrenija zdravoohranenija. Chuvstvitel'nost' k oblucheniju, proizvedennogo Cl. botulinum tipa E, issledovalas' v svjazi s celostnost'ju obluchennyh produktov pitanija. Tret'ja kategorija svjazana s ispol'zovaniem himicheskogo vozdejstvija obluchenija. Naprimer, issledovalos' obluchenie morskih vodoroslej dozami v 0,5 -0,7 Mrad dlja uluchshenija kachestva i vyhoda jekstragirovannogo agara i radiacionnoe uskorenie starenija alkogol'nyh napitkov, osobenno ochishhennyh likerov, dozami do 0,5 Mrad. Krome jetih prakticheskih issledovanij provodilas' shirokaja rabota po fundamental'nym aspektam, vkljuchaja radiochuvstvitel'nost' mikroorganizmov, inaktivaciju fermentov oblucheniem i drugie problemy radiacionnoj himii, svjazannoj s oblucheniem produktov, pitanija.

    This paper describes some -of the work carried out by the Isotopes Section of the Australian Atomic Energy Commission during the last two years, particularly relating to industrial and field tests in co-operation with other organizations. A study of the flow pattern of water in a power-station cooling pond was made, using iodine-131 as tracer. The flow of the water was followed quantitatively throughout the 200 000 000 gallon pond by the use of calibrated underwater scintillation-counters. These experiments showed that the flow pattern was affected by the wind more than by any other factor. In the absence of wind an appreciable fraction of the war m water channelled across the surface of the pond and re-entered the power station within 3-4 hours. This indicated a design defect in the layout of the intake which was subsequently modified. A study of the pattern of flow in a Bach subsider for raw sugar solutions is also described. The hot raw solution after lime treatment enters through a single feed line at the top and clarified solution is taken off by pipelines at six different levels. The solids are taken off at the base. About 5 mc of bromine-82 in solution was injected into the feed line and the appearance of the tracer measured quantitatively by shielded scintillation detectors on each of the six outlet pipes. Analysis of the distribution of activity with time in each line permitted a clear indication of the nature of the flow within the subsider. Finally, a study of the efficiency of mixing in a spiral-type mixer is described. (author) [French] L'auteur decrit certains des travaux accomplis au cours des deux dernieres annees par la Section des isotopes de la Commission australienne de l'energie atomique, notamment les experiences pratiques, industrielles ou autres, entreprises de concert avec d'autres organisations. On a etudie le mouvement des eaux dans le bassin de refroidissement d'une centrale electrique, en utilisant l'iode-131 comme indicateur. Ce mouvement a ete repere quantitativement a travers tout le bassin de 200 millions de gallons a l'aide de compteurs a scintillation etalonnes fonctionnant sous l'eau. On a constate que le circuit emprunte par l'eau etait influence par le vent plus que par tout autre facteur. En absence de vent, une fraction appreciable de l'eau chaude traversait le bassin en surface et revenait a la centrale en l'espace de 3 a 4 heures. Ce fait etait du a un defaut de conception du systeme d'admission de l'eau, defaut auquel il a ete remedie par la suite. L'auteur expose en outre une etude qui a ete faite sur le circuit suivi dans une cuve de Bach par des solutions de sucre brut. Apres traitement a la chaux, la solution chaude de sucre brut penetre par un tuyau d'arrivee aboutissant a la partie superieure de la cuve; la solution clarifiee s'ecoule par des conduites placees a six niveaux differents. Les particules solides sont enlevees a la base. Une quantite d'environ 5 mc de brome-82 solution a ete injectee dans le tuyau d'arrivee et la presence de l'indicateur determinee quantitativement au moyen de detecteurs a scintillation munis d'ecrans et montes sur chacun des six tuyaux de sortie. L'analyse de la repartition de la radioactivite en fonction du temps, dans chaque conduite, a permis de se faire une idee nette du circuit suivi par la solution a l'interieur de la cuve. Enfin, l'auteur etudie l'efficacite d'un melangeur du type helicoidal. (author) [Spanish] El autor describe algunos trabajos realizados en la Seccion de Isotopos de la Comision de Energia Atomica de Australia durante los dos ultimos anos, relativos en particular a ensayos de caracter tecnico ejecutados en cooperacion con otras organizaciones. Los esquemas de circulacion del agua en el estanque de refrigeracion de una central electrica se analizaron con ayuda de yodo-131 como indicador. Se estudio cuantitativamente la circulacion del agua marcada a traves del estanque de 200 millones de galones de capacidad, utilizando contadores de centelleo callibrados instalados debajo del agua. Los experimentos pusieron de relieve que la corriente resultaba mas afectada por el viento que por cualquier otro factor. En ausencia de viento, una proporcion considerable del agua caliente retornaba a la central al cabo de tres o cuatro horas, circulando por la superficie del deposito. Ello puso de manifiesto que el sistema de admision del agua se habia proyectado incorrectamente, por lo que hubo de modificarse. El autor describe asimismo un estudio del esquema de circulacion de las soluciones de azucar bruto en un tanque Bach de sedimentacion. Despues de haber sido tratada con cal, la solucion caliente penetra en el tanque por una tuberia de alimentacion que desemboca en la parte superior del mismo, en tanto que la solucion clarificada se estrae por tuberias situadas a seis niveles distintos. Los solidos precipitados se extraen por la parte inferior. Se inyecto una solucion conteniendo 5 milicuries de bromo-82 en la tuberia de alimentacion y el paso del indicador se midio cuantitativamente a medida que aparecia en las seis tuberias de salida, utilizando detectores de centelleo blindados. Un estudio de la distribucion de la actividad dentro de cada tuberia, en funcion del tiempo, permitio formarse una idea clara de las caracteristicas de la corriente en el tanque de sedimentacion. Por ultimo, el autor estudia el rendimiento de la operacion de mezcla en un mezclador de tipo espiral.

    2015-01-01

    The use of computation and simulation has become an essential part of the scientific process. Being able to transform a theory into an algorithm requires significant theoretical insight, detailed physical and mathematical understanding, and a working level of competency in programming. This upper-division text provides an unusually broad survey of the topics of modern computational physics from a multidisciplinary, computational science point of view. Its philosophy is rooted in learning by doing (assisted by many model programs), with new scientific materials as well as with the Python progr

  6. Recent findings concerning childhood food insecurity.

    Science.gov (United States)

    Kursmark, Meredith; Weitzman, Michael

    2009-05-01

    Food insecurity is a relatively new measure of household and child malnutrition. This paper reviews recent studies that have examined aspects of its etiology and adverse child health and development. Smoking by adults in children's homes has recently been found to be highly associated with childhood food insecurity. Much recent research has also examined the relationship between food insecurity and childhood obesity, and thus far, whereas suggestive, results are conflicting. Some studies have found that parenting practices and parental depression are factors that link household food insecurity with childhood obesity. Other health outcomes recently shown to be associated with food insecurity include undernutrition, decreased mental proficiency, increased developmental risk, adverse pregnancy outcomes, and poor health status. Most of the studies of food insecurity to date have come from the USA. There is, however, absolutely no reason to believe that this measure, and the negative child health outcomes associated with it, does not apply to other developed nations. Similarly, it is likely that children and families living in developing countries suffer a greater prevalence and severity of food insecurity and its negative consequences. Childhood food insecurity has numerous significant negative effects on childhood health and development, may be associated with obesity, and occurs much more often in impoverished homes with adult smokers.

    Emission spectroscopy, are already well-established instrumental analytical technique, has in recent years known important developments. Two mains factors are responsible; firstly the demands of metallurgy for purer and purer materials or alloys which are increasingly complex and difficult to analyse by chemical means; secondly, progress in optics, especially in the production of gratings, and in electronics in the field of photomultiplier tubes. We will not here catalogue all the new applications and methods, but we will consider a few amongst the most representative outside the conventional field. (author) [French] La spectroscopie d'emission, technique analytique instrumentale deja ancienne, a pris, depuis quelques annees, une extension notable. Deux facteurs principaux ont contribue a ce succes: d'une part, l'exigence de la metallurgie en materiaux de plus en plus pur ou en alliages de plus en plus complexes, difficiles a analyser chimiquement, d'autre part, les progres realises en optique, principalement dans la fabrication des reseaux, et en electronique dans le domaine des tubes photomultiplicateurs. Nous ne ferons pas ici le recensement de toutes les applications ou methodes nouvelles, mais nous en choisirons quelques unes des plus representatives hors du domaine classique. (auteur)

    The goal of General Game Playing (GGP) has been to develop computer programs that can perform well across various game types. It is natural for human game players to transfer knowledge from games they already know how to play to other similar games. GGP research attempts to design systems that work well across different game types, including unknown new games. In this review, we present a survey of recent advances (2011 to 2014) in GGP for both traditional games and video games. It is notable that research on GGP has been expanding into modern video games. Monte-Carlo Tree Search and its enhancements have been the most influential techniques in GGP for both research domains. Additionally, international competitions have become important events that promote and increase GGP research. Recently, a video GGP competition was launched. In this survey, we review recent progress in the most challenging research areas of Artificial Intelligence (AI) related to universal game playing. PMID:26380375

    The recent diagnostic developments on the large helical device (LHD) are described briefly. LHD is the largest helical machine with all superconducting coils, and its purpose is to prove the ability of a helical system to confine a fusion-relevant plasma in steady state. According to the missions of LHD research, the diagnostic devices are categorized as follows: diagnostics for (i) high nτ E T plasmas and transport physics; (ii) magnetohydrodynamic stability; (iii) long pulse operation and divertor function; and (iv) energetic particles. These are briefly described focusing on the recent developments of the devices. Since the LHD experiment started in March 1998, five series of experimental campaigns have been carried out. The LHD diagnostics during these periods were operated successfully, and contributed to the analysis of the experimental results

    DNA based synthetic molecular walkers are reminiscent of biological protein motors. They are powered by hybridization with fuel strands, environment induced conformational transitions, and covalent chemistry of oligonucleotides. Recent developments in experimental techniques enable direct observation of individual walkers with high temporal and spatial resolution. The functionalities of state-of-the-art DNA walker systems can thus be analyzed for various applications. Herein we review recent progress on DNA walker principles and characterization methods, and evaluate various aspects of their functions for future applications. Copyright © 2014 Elsevier Ltd.

    There is now ample evidence of the ecological impacts of recent climate change, from polar terrestrial to tropical marine environments. The responses of both flora and fauna span an array of ecosystems and organisational hierarchies, from the species to the community levels. Despite continued uncertainty as to community and ecosystem trajectories under global change, our review exposes a coherent pattern of ecological change across systems. Although we are only at an early stage in the projected trends of global warming, ecological responses to recent climate change are already clearly visible. (Author)

    This paper exploits a Danish spatial dispersal policy on refugees which can be regarded as a natural experiment to investigate the influence of regional factors on recent immigrants' location choices. The main push factors are lack of co-nationals and immigrants. Additional push factors are lack...... of rental, including social, housing and lack of institutions for qualifying educations which explain why recent immigrants are attracted to large cities. Finally, placed refugees tend to leave locations with relatively high regional unemployment and there is indirect evidence of welfare seeking....

    This paper gives a general overview and describes the principles of the main laser-based techniques for physical and chemical analysis, and of their recent developments. Analytical techniques using laser radiations were actually developed at the end of the 1970's. The recent evolutions concern the 3 principal techniques of laser spectroscopy currently used: Raman, fluorescence (atomic and molecular) and ablation (ICP laser ablation-plasma coupling, optical emission spectroscopy on laser-induced plasma). The description of these different techniques is illustrated with some examples of applications. (J.S.)

  15. Sublingual Immunotherapy: Recent Advances

    Directory of Open Access Journals (Sweden)

    Enrico Compalati

    2013-01-01

    Full Text Available The practice of administering sublingual immunotherapy for respiratory allergy is gaining more and more diffusion worldwide as a consequence of the robust demonstration of clinical efficacy and safety provided by recent high-powered and well-designed studies, confirming for individual seasonal allergens the results of previous metanalyses in adult and pediatric populations. Preliminary evidence derives from recent rigorous trials on perennial allergens, like house dust mites, and specifically designed studies addressed the benefits on asthma. Emerging research suggests that SLIT may have a future role in other allergic conditions such as atopic dermatitis, food, latex and venom allergy. Efforts to develop a safer and more effective SLIT for inhalant allergens have led to the development of allergoids, recombinant allergens and formulations with adjuvants and substances targeting antigens to dendritic cells that possess a crucial role in initiating immune responses. The high degree of variation in the evaluation of clinical effects and immunological changes requires further studies to identify the candidate patients to SLIT and biomarkers of short and long term efficacy. Appropriate management strategies are urgently needed to overcome the barriers to SLIT compliance.

    2013-05-01

    Full Text Available The aim of this pilot study was the evaluation of the neuro-music therapy approach as a new treatment option for patients with recent-onset tinnitus whose tinnitus symptoms were enduring after initial pharmacological treatment. In all, 15 patients with recent-onset tinnitus took part in our manualized short-term music-therapeutic treatment. Tinnitus severity and individual tinnitus distress were assessed by the German version of the tinnitus questionnaire (TQ and the Attention and Performance Self-Assessment Scale (APSA at three different measurement times: baseline (T0, start of treatment (T1, and end of treatment (T2. Score changes in TQ and APSA from start to end of treatment indicated significant improvements in tinnitus-related distress. According to the Jacobson and Truax reliable change index (RC, 73.3% of the patients showed a reliable reduction in individual TQ-score. The neuro-music therapy for recent-onset tinnitus according to the “Heidelberg Model” introduced in this pilot study seems to provide an effective treatment option for patients with recent-onset tinnitus.

Electrochemical glycoprotein sensors are constructed by combining metal and carbon electrodes with glycoprotein-selective binding elements including antibodies, lectin, phenylboronic acid and molecularly imprinted polymers. A recent trend in the preparation of glycoprotein sensors is the successful use of nanomaterials such as graphene, carbon nanotube, and metal nanoparticles. These nanomaterials are extremely useful for improving the sensitivity of glycoprotein sensors. This review focuses mainly on the protocols for the preparation of glycoprotein sensors and the materials used. Recent improvements in glycoprotein sensors are discussed by grouping the sensors into several categories based on the materials used as recognition elements.

    Full Text Available Carotenoids are substantially hydrophobic antioxidants. Hydrophobicity is this context is rather a disadvantage, because their utilization in medicine as antioxidants or in food chemistry as colorants would require some water dispersibility for their effective uptake or use in many other ways. In the past 15 years several attempts were made to synthetize partially hydrophilic carotenoids. This review compiles the recently synthetized hydrophilic carotenoid derivatives.

    Olive, J

    1995-11-01

    This course is part of the ENSTA 3rd year thermal hydraulics program (nuclear power option). Its purpose is to provide the theoretical basis and main physical notions pertaining to two-phase flow, mainly focussed on water-steam flows. The introduction describes the physical specificities of these flows, emphasizing their complexity. The mathematical bases are then presented (partial derivative equations), leading to a one-dimensional type, simplified description. Balances drawn up for a pipe length volume are used to introduce the mass conservation. motion and energy equations for each phase. Various postulates used to simplify two-phase models are presented, culminating in homogeneous model definitions and equations, several common examples of which are given. The model is then applied to the calculation of pressure drops in two-phase flows. This involves presenting the models most frequently used to represent pressure drops by friction or due to pipe irregularities, without giving details (numerical values of parameters). This chapter terminates with a brief description of static and dynamic instabilities in two-phase flows. Finally, heat transfer conditions frequently encountered in liquid-steam flows are described, still in the context of a 1D model. This chapter notably includes reference to under-saturated boiling conditions and the various forms of DNB. The empirical heat transfer laws are not discussed in detail. Additional material is appended, some of which is in the form of corrected exercises. (author). 6 appends.

    MCNP is a widely used and actively developed Monte Carlo radiation transport code. Many important features have recently been added and more are under development. Benchmark studies not only indicate that MCNP is accurate but also that modern computer codes can give answers basically as accurate as the physics data that goes in them. Even deep penetration problems can be correct to within a factor of two after 10 to 25 mean free paths of penetration. And finally, Monte Carlo calculations, once thought to be too expensive to run routinely, can now be run effectively on desktop computers which compete with the supercomputers of yesteryear. 21 refs., 3 tabs

    Phytosterols and their oxidation products have become increasingly investigated in recent years with respect to their roles in diet and nutrition. We present a comprehensive review of recent literature on Phytosterol Oxidation Products (POP) identifying critical areas for future investigation. It is evident that POP are formed on food storage/preparation; are absorbed and found in human serum; do not directly affect cholesterol absorption; have evidence of atherogenicity and inflammation; have distinct levels of cytotoxicity; are implicated with high levels of oxidative stress, glutathione depletion, mitochondrial dysfunction and elevated caspase activity.

    The number of cases of lymphocytic hypophysitis is small, although the condition is not rare. For optimal therapy, the correct diagnosis from imaging, immunological studies, and pathological findings from a pituitary biopsy is important. Recently, anti-Rabphilin antibody has been proposed to be a biomarker for lymphocytic infundibulo-neurohypophysitis. Immunological disorders such as anti-Pit-1 antibody syndrome are similar to the pathogenesis of lymphocytic hypophysitis. Moreover, recent immune checkpoint blockade such ipilimumab has been shown to induce anti-CTLA-4-related hypophysitis. In the future, elucidating the immunological mechanism and establishing a suitable therapy will be necessary for accurate long-term prognosis.

  18. Overpressures: Causal Mechanisms, Conventional and Hydromechanical Approaches Surpressions : origine, approches conventionnelle et hydromécanique

    Directory of Open Access Journals (Sweden)

    Grauls D.

    2006-12-01

    -rock sealing efficiency depend on the subtle interaction, through time, between overpressure and minimum principal stress regimes. On rencontre souvent des régimes anormaux de pression dans les bassins sédimentaires. Les relations entre la contrainte verticale effective et la porosité ont été appliquées, depuis 1970, dans la région de la Gulf Coast, afin d'évaluer ces surpressions. Des résultats ont été obtenus en faisant appel à la sismique et à la modélisation de bassin dans les bassins tertiaires de sable argileux à contrainte verticale dominante et en déséquilibre de compaction. Cependant, les surpressions d'origines différentes et/ou additionnelles (contrainte tectonique, génération d'hydrocarbures, contrainte thermique, transfert lié aux failles, fracturation hydraulique ne peuvent pas être quantifiées en utilisant cette approche. En plus des méthodes conventionnelles, une approche hydromécanique est proposée. Pour toute profondeur, la limite supérieure est contrôlée par les conditions de fracturation hydraulique ou par la réactivation de failles. La fracturation hydraulique suppose un système ouvert par période, en régime de contrainte effective mineure proche de zéro. Une connaissance approfondie des régimes de contraintes tectoniques actuels permet une estimation directe de l'évolution de la contrainte minimale. Une évaluation quantitative de la pression avec la profondeur est donc possible, puisque dans les systèmes géologiques compartimentés et/ou non drainés, les régimes de pression, quelles que soient leurs origines, ont tendance à atteindre rapidement une valeur proche de la contrainte principale mineure. Ainsi, l'évaluation de la surpression sera améliorée, puisque cette méthodologie peut être appliquée à divers environnements géologiques où les surpressions ont d'autres origines, les mécanismes étant souvent combinés. Cependant, les tendances de l'évolution de pression dans les zones de transition sont

  19. Primary hyperparathyroidism: recent advances.

    Science.gov (United States)

    Walker, Marcella D; Bilezikian, John P

    2018-07-01

    The purpose of this review is to describe recent advances and changes in the evaluation and management of primary hyperparathyroidism (PHPT). Although it has long been recognized that asymptomatic PHPT is associated with bone loss, particularly at cortical skeletal sites when evaluated with dual-energy X-ray absorptiometry, new imaging techniques suggest that trabecular skeletal deterioration as well as clinically silent vertebral fractures and nephrolithiasis are common. Nonclassical targets of asymptomatic PHPT as well as the effect of vitamin D deficiency and treatment upon PHPT presentation have been the subject of recent intense investigation. Randomized clinical trials are now available regarding the effect of parathyroidectomy (PTX) upon both classical and nonclassical target organs. They have confirmed results from observational studies with regard to the skeletal benefits of PTX but have not consistently shown improvements in nonclassical symptoms. These findings have led to recommendations for more extensive renal and skeletal evaluation and broader criteria for PTX in PHPT. In addition to dual-energy X-ray absorptiometry, vertebral and renal imaging is recommended. When available, trabecular imaging techniques may be helpful. PTX criteria now include subclinical kidney stones, vertebral fractures and hypercalciuria, in addition to those based on age, serum calcium, bone densitometry and renal function.

  20. Recent Advances of VCSEL Photonics

    2006-12-01

    A vertical-cavity surface emitting laser (VCSEL) was invented 30 years ago. A lot of unique features can be expected, such as low-power consumption, wafer-level testing, small packaging capability, and so on. The market of VCSELs has been growing up rapidly in recent years, and they are now key devices in local area networks using multimode optical fibers. Also, long wavelength VCSELs are currently attracting much interest for use in single-mode fiber metropolitan area and wide area network applications. In addition, a VCSEL-based disruptive technology enables various consumer applications such as a laser mouse and laser printers. In this paper, the recent advance of VCSEL photonics will be reviewed, which include the wavelength extension of single-mode VCSELs and their wavelength integration/control. Also, this paper explores the potential and challenges for new functions of VCSELs toward optical signal processing.

  14. Self-Reported Health Among Recently Incarcerated Mothers.

    Turney, Kristin; Wildeman, Christopher

    2015-10-01

    We examined self-reported health among formerly incarcerated mothers. We used data from the Fragile Families and Child Wellbeing Study (n = 4096), a longitudinal survey of mostly unmarried parents in urban areas, to estimate the association between recent incarceration (measured as any incarceration in the past 4 years) and 5 self-reported health conditions (depression, illicit drug use, heavy drinking, fair or poor health, and health limitations), net of covariates including health before incarceration. In adjusted logistic regression models, recently incarcerated mothers, compared with their counterparts, have an increased likelihood of depression (odds ratio [OR] = 1.60; 95% confidence interval [CI] = 1.18, 2.17), heavy drinking (OR = 1.79; 95% CI = 1.19, 2.68), fair or poor health (OR = 1.49; 95% CI = 1.08, 2.06), and health limitations (OR = 1.78; 95% CI = 1.27, 2.50). This association is similar across racial/ethnic subgroups and is larger among mothers who share children with fathers who have not been recently incarcerated. Recently incarcerated mothers struggle with even more health conditions than expected given the disadvantages they experience before incarceration. Furthermore, because incarceration is concentrated among those who are most disadvantaged, incarceration may increase inequalities in population health.

    Cyclodextrins (CDs) are cyclic oligosaccharides comprised of six or more glucose units connected by alpha-1,4 bonds. They have hydrophobic cavities with a hydrophilic exterior, and are versatile receptors for a variety of substrates. This ability allows them to be applied in many fields, as distinct as supramolecular chemistry, nanotechnology, pharmaceuticals, green chemistry, agrochemicals, analytical chemistry, toiletries, foods, and cosmetics. This review summarizes several aspects related to the physico-chemical properties of CDs and discusses their potential applications illustrated by recent examples. The prospects for their use in several areas are also described. (author)

  16. Recent Advances in Electrochemical Immunosensors

    Directory of Open Access Journals (Sweden)

    Benoît Piro

    2017-04-01

    Full Text Available Immunosensors have experienced a very significant growth in recent years, driven by the need for fast, sensitive, portable and easy-to-use devices to detect biomarkers for clinical diagnosis or to monitor organic pollutants in natural or industrial environments. Advances in the field of signal amplification using enzymatic reactions, nanomaterials such as carbon nanotubes, graphene and graphene derivatives, metallic nanoparticles (gold, silver, various oxides or metal complexes, or magnetic beads show how it is possible to improve collection, binding or transduction performances and reach the requirements for realistic clinical diagnostic or environmental control. This review presents these most recent advances; it focuses first on classical electrode substrates, then moves to carbon-based nanostructured ones including carbon nanotubes, graphene and other carbon materials, metal or metal-oxide nanoparticles, magnetic nanoparticles, dendrimers and, to finish, explore the use of ionic liquids. Analytical performances are systematically covered and compared, depending on the detection principle, but also from a chronological perspective, from 2012 to 2016 and early 2017.

The bibliographic data will be grouped, on the basis of biological information, in two great categories: reports in which the extract plants bioactivity is reported and the identification of each flavonoid is present or not, and reports in which the anticancer activity is attributable to purified and identified flavonoids from plants. Wherever possible, the targets and mechanisms of action as well as the structure-activity relationships of the molecules will be reported. Also, in the review it was thoroughly investigated the recent discovery on flavonoids containing the 2-phenyl-4H-chromen-4-one system even if some examples of unusual flavonoids, bearing a non-aromatic B-ring or other ring condensed to the base structure are reported.

    Measurements of the cross sections of the production of two electroweak gauge bosons constitute stringent tests of the electroweak sector of the Standard Model and provide a model-independent means to search for new physics at the TeV scale. We present recent ATLAS measurements of inclusive and differential cross sections for WW, WZ, ZZ and Z + photon at centre of mass energies of 8 TeV and 13 TeV. Large next-to-next-to-leading order QCD corrections were recently calculated and are confronted with the measurements. We also present recent ATLAS measurements of inclusive cross sections for electroweak production of WZ + 2 jets and production of Z + di-photon at 8 TeV. Differential distributions sensitive to anomalous triple and quartic gauge couplings have been studied and limits on new physics have been derived.

    Studies have been made of the liquid scintillation counting system with the objective of optimizing detection sensitivity as expressed by a function of sample volume, efficiency and background. The investigation included a review of scintillator composition. A dioxane-naphthalene-water system having a water content of 18.6% was selected as the most satisfactory composition. Further studies of counting cell geometry and scintillator volume have led to the use of a cylindrical container of 'Teflon' with high gain quartz face photomultipliers in direct contact with the solution. This system gave a tritium detection sensitivity corresponding to a concentration of 0.55 x 10{sup -12} c/ml at an efficiency of 6.9% and a background of 52 cpm. A water sample volume of 31.6 ml was used with total scintillator volume of 170 ml. An internal Co{sup 57} source was found to be a suitable monitor of tritium-counting efficiency in the range 2 to 7% with a standard deviation of 0.1%. It has the advantage over previous methods in that it provided a rapid efficiency determination without modification of the sample. Studies of background reduction were made to evaluate the contribution of luminous interaction and cosmic radiation. A plastic envelope anticoincidence shield was used in the study. Long term effects on stability of the system caused by sample deterioration and counting equipment drifts were evaluated. (author) [French] Les auteurs ont etudie un dispositif de comptage a scintillateur liquide, en vue de rendre optimum la sensibilite de la detection, definie en fonction du volume de l'echantillon, du rendement de comptage et du bruit de fond. Les recherches ont porte notamment sur la composition du scintillateur. On a choisi un melange dioxane-naphthalene-eau, dans lequel cette derniere entrait pour 18,6%, parce que sa composition s'est revelee la plus satisfaisante. D'autres etudes, qui portaient sur la geometrie de la cellule de comptage et le volume du scintillateur, ont amene les auteurs a utiliser un recipient cylindrique en ''Teflon'' et des photomultiplicateurs a fenetre en quartz a gain eleve, en contact direct avec la solution. Ce dispositif permet d'obtenir une sensiblite de detection correspondant a une concentration en tritium de 0,55 x 10{sup -12} c/ml, avec un rendement de 6,9% et un bruit de fond de 52 cpm. Les auteurs ont utilise un echantillon d'eau de 31,6 ml, le volume total du scintillateur etant de 170 ml. Les auteurs ont constate qu'une source interne de cobalt-57 permettait de controler efficacement le rendement du comptage du tritium, dans la gamme allant de 2 a 7%, avec un ecart type de 0,1%. Par rapport aux methodes plus anciennes, ce procede offre l'avantage de permettre une determination rapide du rendement sans modifier l'echantillon. Les auteurs ont etudie la reduction du bruit de fond, pour evaluer la part de l'interaction lumineuse et celle des rayons cosmiques; ils ont utilise a cette fin une protection d'anticoincidence, a enveloppe en matiere plastique. Ils ont evalue dans quelle mesure la deterioration des echantillons et les derives du materiel de comptage tendent a reduire, a longue echeance, la stabilite du dispositif. (author) [Spanish] Se han llevado a cabo estudios sobre el sistema de recuento por centelleo de liquidos con objeto de establecer las condiciones optimas de sensibilidad para la deteccion, expresadas en funcion del volumen de la muestra, del rendimiento de recuento y de la actividad de fondo. Estas investigaciones comprendieron un estudio de la composicion del centelleador. Se ha elegido como composicion mas satis- factoria una mezcla de dioxano-naftaleno-agua, esta ultima en la proporcion de 18,6%. Los nuevos estudios realizados acerca de la geometria de la celda de recuento y el volumen del centelleador han conducido al empleo de un recipiente cilindrico de ''Teflon'' con fotomultiplicadore s de elevada ganancia, dotados de una ventana de cuarzo, en contacto directo con la solucion. Con este sistema se ha logrado una sensibilidad de deteccion correspondiente a una concentracion de tritio de 0,55 x 10{sup -12} c/ml con un rendimiento de 6,9% y un fondo de 52 imp/min. Se utilizo una muestra de agua de 31,6 ml y un centelleador de 170 mi de volumen total. Se ha podido comprobar que una fuente interna de 57Co constituye un medio adecuado para controlar el rendimiento de recuento del tritio en el intervalo comprendido entre 2 y 7%, con una desviacion standard de 0,1%. Respecto de los metodos anteriores, posee la ventaja de que permite una rapida valoracion del rendimiento sin necesidad de modificar la muestra. Se efectuaron estudios sobre la reduccion del fondo con miras a evaluar la influencia de la interaccion luminosa y de las radiaciones cosmicas. En el estudio se empleo un blindaje de anticoincidencia con una envoltura de material plastico. Se determinaron los efectos a largo plazo ejercidos sobre la estabilidad del sistema por la deterioracion de las muestras y las desviaciones en el equipo de recuento.

  12. Climate change: Recent findings

    1993-08-01

    In the late eighties several reports have been published on climate change and sea level rise. In the meantime insights may have changed due to the availability of better and more observations and/or more advanced climate models. The aim of this report is to present the most recent findings with respect to climate change, in particular of sea level rise, storm surges and river peak flows. These climate factors are important for the safety of low-lying areas with respect to coastal erosion and flooding. In the first chapters a short review is presented of a few of the eighties reports. Furthermore, the predictions by state of the art climate models at that time are given. The reports from the eighties should be considered as 'old' information, whereas the IPCC supplement and work, for example, by Wigley should be considered as new information. To assess the latest findings two experts in this field were interviewed: dr J. Oerlemans and dr C.J.E. Schuurmans, a climate expert from the Royal Netherlands Meteorological Institute (KNMI). Their views are presented together with results published in recent papers on the subject. On the basis of this assessment, the report presents current knowledge regarding predictions of climate change (including sea-level rise) over the next century, together with an assessment of the uncertainties associated with these predictions. 14 figs., 11 tabs., 24 refs

  13. Recent life events and psychosis: The role of childhood adversities.

    Life events are commonly reported to be related to psychosis. However, less attention has been given to the role that recent events play on psychosis, in relation to exposure to childhood adversity. The current study aimed to evaluate the relationship between recent events and psychosis, taking into account the role of early adversities. 78 psychotic patients and 156 controls were enrolled. Childhood adversity was evaluated using a validated semi-structured interview and the Childhood Experience of Care and Abuse Questionnaire. Recent events were recorded using a semi-structured interview with a normative and contextual approach. The diagnosis of psychosis was made according to Jablenski's criteria. Chi-square, t-test, odds ratio, and binary logistic regression statistical analyses were performed. Psychotic patients reported an excess of recent events. The occurrence of more than one recent event increased the risk of psychosis; there was a cumulative effect between recent and childhood events on psychosis. Recent events were significantly related to psychosis, even in the absence of childhood adversity or when adjusted for it. Our findings suggested that the effect of recent events on psychosis may be amplified by previous exposure to early adversity. Recent events alone, could be also linked to psychosis independently of childhood adversity. Copyright © 2017 Elsevier B.V. All rights reserved.

    Schizophrenia is a highly disabling disorder whose causes remain to be better understood, and treatments have to be improved. However, several recent advances have been made in diagnosis, etiopathology, and treatment. Whereas reliability of diagnosis has improved with operational criteria, including Diagnostic and Statistical Manual of Mental Disorders, (DSM) Fifth Edition, validity of the disease boundaries remains unclear because of substantive overlaps with other psychotic disorders. Recent emphasis on dimensional approaches and translational bio-behavioral research domain criteria may eventually help move toward a neuroscience-based definition of schizophrenia. The etiology of schizophrenia is now thought to be multifactorial, with multiple small-effect and fewer large-effect susceptibility genes interacting with several environmental factors. These factors may lead to developmentally mediated alterations in neuroplasticity, manifesting in a cascade of neurotransmitter and circuit dysfunctions and impaired connectivity with an onset around early adolescence. Such etiopathological understanding has motivated a renewed search for novel pharmacological as well as psychotherapeutic targets. Addressing the core features of the illness, such as cognitive deficits and negative symptoms, and developing hypothesis-driven early interventions and preventive strategies are high-priority goals for the field. Schizophrenia is a severe, chronic mental disorder and is among the most disabling disorders in all of medicine. It is estimated by the National Institute of Mental Health (NIMH) that 2.4 million people over the age of 18 in the US suffer from schizophrenia. This illness typically begins in adolescence and derails the formative goals of school, family, and work, leading to considerable suffering and disability and reduced life expectancy by about 20 years. Treatment outcomes are variable, and some people are successfully treated and reintegrated (i.e. go back to work

  1. Oklahoma’s recent earthquakes and saltwater disposal

    Walsh, F. Rall; Zoback, Mark D.

    2015-01-01

    Over the past 5 years, parts of Oklahoma have experienced marked increases in the number of small- to moderate-sized earthquakes. In three study areas that encompass the vast majority of the recent seismicity, we show that the increases in seismicity follow 5- to 10-fold increases in the rates of saltwater disposal. Adjacent areas where there has been relatively little saltwater disposal have had comparatively few recent earthquakes. In the areas of seismic activity, the saltwater disposal principally comes from “produced” water, saline pore water that is coproduced with oil and then injected into deeper sedimentary formations. These formations appear to be in hydraulic communication with potentially active faults in crystalline basement, where nearly all the earthquakes are occurring. Although most of the recent earthquakes have posed little danger to the public, the possibility of triggering damaging earthquakes on potentially active basement faults cannot be discounted.

  5. Global warming update: Recent scientific findings

    International Nuclear Information System (INIS)

    Anon.

    1992-01-01

    This study, from the George C. Marshall Institute, considers recent scientific findings on the extent of human-induced global warming. The earth's temperature has risen by approximately half a degree Celsius in the last 100 years, coinciding with a substantial increase in greenhouse gases in the atmosphere, apparently the result of human activity. Several scientific groups have concluded that manmade emissions of greenhouse gases has produced much or all of the recent rise in global temperatures. They predict a doubling of carbon dioxide by the mid-21st century resulting in a global temperature rise of 5 degrees C and causing severe disruptions in the earth's ecosystem. The available data on climatic change, however, do not support these predictions, nor do they support the idea that human activity has caused, or will cause, a dangerous increase in global temperatures. Enormous economic stakes ride on government decisions about carbon taxes and other CO 2 emission restrictions. Attention must be paid to the scientific evidence, no matter how contrary to popular opinion its implications appear to be. The discussion is divided into five parts: introduction; Are the Greenhouse Forecasts Reliable?; The Cause of Recent Climate Changes; New Results on Global Flooding; Conclusions; Policy Implications. 27 refs., 9 figs

  7. Mars Recent Climate Change Workshop

    2012-11-01

    Mars Recent Climate Change Workshop NASA/Ames Research Center May 15-17, 2012 Climate change on Mars has been a subject of great interest to planetary scientists since the 1970's when orbiting spacecraft first discovered fluvial landforms on its ancient surfaces and layered terrains in its polar regions. By far most of the attention has been directed toward understanding how "Early Mars" (i.e., Mars >~3.5 Gya) could have produced environmental conditions favorable for the flow of liquid water on its surface. Unfortunately, in spite of the considerable body of work performed on this subject, no clear consensus has emerged on the nature of the early Martian climate system because of the difficulty in distinguishing between competing ideas given the ambiguities in the available geological, mineralogical, and isotopic records. For several reasons, however, the situation is more tractable for "Recent Mars" (i.e., Mars during past 20 My or so). First, the geologic record is better preserved and evidence for climate change on this time scale has been building since the rejuvenation of the Mars Exploration Program in the late 1990's. The increasing coverage of the planet from orbit and the surface, coupled with accurate measurements of surface topography, increasing spatial resolution of imaging cameras, improved spectral resolution of infrared sensors, and the ability to probe the subsurface with radar, gamma rays, and neutron spectroscopy, has not only improved the characterization of previously known climate features such as polar layered terrains and glacier-related landforms, but has also revealed the existence of many new features related to recent climate change such as polygons, gullies, concentric crater fill, and a latitude dependent mantle. Second, the likely cause of climate change - spin axis/orbital variations - is more pronounced on Mars compared to Earth. Spin axis/orbital variations alter the seasonal and latitudinal distribution of sunlight, which can

  12. Recent development of hydrodynamic modeling

    Hirano, Tetsufumi

    2014-09-01

    In this talk, I give an overview of recent development in hydrodynamic modeling of high-energy nuclear collisions. First, I briefly discuss about current situation of hydrodynamic modeling by showing results from the integrated dynamical approach in which Monte-Carlo calculation of initial conditions, quark-gluon fluid dynamics and hadronic cascading are combined. In particular, I focus on rescattering effects of strange hadrons on final observables. Next I highlight three topics in recent development in hydrodynamic modeling. These include (1) medium response to jet propagation in di-jet asymmetric events, (2) causal hydrodynamic fluctuation and its application to Bjorken expansion and (3) chiral magnetic wave from anomalous hydrodynamic simulations. (1) Recent CMS data suggest the existence of QGP response to propagation of jets. To investigate this phenomenon, we solve hydrodynamic equations with source term which exhibits deposition of energy and momentum from jets. We find a large number of low momentum particles are emitted at large angle from jet axis. This gives a novel interpretation of the CMS data. (2) It has been claimed that a matter created even in p-p/p-A collisions may behave like a fluid. However, fluctuation effects would be important in such a small system. We formulate relativistic fluctuating hydrodynamics and apply it to Bjorken expansion. We found the final multiplicity fluctuates around the mean value even if initial condition is fixed. This effect is relatively important in peripheral A-A collisions and p-p/p-A collisions. (3) Anomalous transport of the quark-gluon fluid is predicted when extremely high magnetic field is applied. We investigate this possibility by solving anomalous hydrodynamic equations. We found the difference of the elliptic flow parameter between positive and negative particles appears due to the chiral magnetic wave. Finally, I provide some personal perspective of hydrodynamic modeling of high energy nuclear collisions

  13. Recent advances in Broomrapes research

    Full Text Available Orobanchaceae (broomrapes is a morphologically diverse family of predominantly herbaceous, parasitic plants. The majority of species are facultative or obligate root parasites that subsist on broad-leaf plants, thereby depleting them of nutrients, minerals and water. The taxonomy status of the family Orobanchaceae among other flowering plants is often subject of debate. They possess only a few morphological features suitable for taxonomy purposes and yet even they are quite changeable. The variability within the species is too high and hampers the attempts to create proper determination keys. During last two decades several molecular markers were used for reevaluate taxonomy, biodiversity and phylogenetic relationships within the family. Recent investigations supported by molecular taxonomy analyses have resulted in re-definition of Orobanchaceae family. According to this classification Orobanchaceae consists of 89 genera, containing 2061 species. On the Balkans the family Orobanchaceae is represented by 3 genera: Orobanche includes 25 species; Phelipanche comprises of 9 species and some putative hybrids; Diphelypaea occurs with single species, Diphelypaea boissieri, in Macedonia and Greece. Only a few recent studies based on modern methods took place during last decade. Their findings confirmed differences between Phelipanche and Orobanche genera, but raised new question about their internal structure. Several broomrape species parasitize important crops. They are widely spread in Bulgaria, Southern Europe, Russia, Middle East and Northern Africa. They cause losses in crop productivity estimated at hundreds of millions of dollars annually than affect the livelihoods of 100 million farmers. A wide variety of approaches have been explored to control broomrapes, but none have been found to be sufficiently effective and affordable. The new findings about their life cycle and the recent genomic project focused on sequences of Ph. aegyptiaca genome

    Dengue is an emerging threat to billions of people worldwide. In the last 20 years, the incidence has increased four-fold and this trend appears to be continuing. Caused by one of four viral serotypes, dengue can present as a wide range of clinical phenotypes with the severe end of the spectrum being defined by a syndrome of capillary leak, coagulopathy, and organ impairment. The pathogenesis of severe disease is thought to be in part immune mediated, but the exact mechanisms remain to be defined. The current treatment of dengue relies on supportive measures with no licensed therapeutics available to date. There have been recent advances in our understanding of a number of areas of dengue research, of which the following will be discussed in this review: the drivers behind the global dengue pandemic, viral structure and epitope binding, risk factors for severe disease and its pathogenesis, as well as the findings of recent clinical trials including therapeutics and vaccines. We conclude with current and future dengue control measures and key areas for future research. PMID:26918159

    Marcos Julio Caruso Alcocer

    Full Text Available Summary Food allergy is a public health issue that has significantly increased worldwide in the past decade, affecting consumers’ quality of life and making increasing demands on health service resources. Despite recent advances in many areas of diagnosis and treatment, our general knowledge of the basic mechanisms of the disease remain limited i.e., not at pace with the exponential number of new cases and the explosion of new technologies. Many important key questions remain: What defines a major allergen? Why do some individuals develop food allergies and others do not? Which are the environmental factors? Could the environmental factors be monitored through epigenetics or modified by changes in the microbiome? Can tolerance to food be induced? Why are some foods more likely to trigger allergies than others? Does the route and timing of exposure have any role on sensitization? These and many other related questions remain unanswered. In this short review some of these topics are addressed in the light of recent advances in the area.

    Full Text Available In recent years the fishery always has been a growing industry. However, fishery like the other industries had faced with some limitations. Pollution of water resources, fight disease and efforts to increase production efficiency have been important challenges of fishing industry in recent years. Also, world statistics show that the fishing did not have much grown in recent years. On the other hand, aquaculture of marine fish as new industry can be a reliable solution for the management of aquatic ecosystems and restore these reserves, and in recent years, it always has been a significant growth in the production. So far, several species such as Mahimahi (Coryphaena hippurus, European seabass (Dicentrarchus labrax, Cobia (Rachycentron canadum and silver pomfret (Pampus argenteus have been successfully produced and marketed with different aquaculture methods (i.e. cage culture and pen culture. The aim of this study was to summarize marine fish production methods with an emphasis on the production of silver pomfret, as a commercial species and the study of the opportunities and challenges facing this sector in the future.

    The emission of sulfur oxides can have adverse effects on the environment. Biodesulfurization of fossil fuels is attracting more and more attention because such a bioprocess is environmentally friendly. Some techniques of desulfurization have been used or studied to meet the stricter limitation on sulfur content in China. Recent advances have demonstrated the mechanism and developments for biodesulfurization of gasoline, diesel and crude oils by free cells or immobilized cells. Genetic technology was also used to improve sulfur removal efficiencies. In this review, we summarize recent progress mainly in China on petroleum biodesulfurization.

Deflation has been referred to as a possible continuance after a financial bubble because often but not always deflation follows. Deflation often results in financial and economic crises. Financial and economic crises affect the architecture of the monetary system, while a change in the system may affect the role of the dollar, the euro and the yen.

  10. Recent advances in female sexual dysfunction.

    2000-06-01

    Female sexuality has received little scientific study. Recently, increased interest in this field has generated new research in the epidemiology, pathophysiology, and pharmacotherapy of female sexual dysfunction (FSD). A new FSD classification system has been proposed. Although sexual difficulties are highly prevalent among women, the degree of associated distress is unknown. Risk factors for FSD are probably both psychologic and physiologic. Aging or menopause is associated with lubrication difficulties, which can be treated with hormone replacement. Hysterectomy seems more likely to result in improvement rather then deterioration of sexual functioning. Depression may be a predictor of sexual dysfunction after hysterectomy. Vasoactive agents are currently being evaluated as treatment for female sexual arousal disorder. The most important advance in the study of female sexual function is the recent surge of interest in this relatively unexplored field.

    Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease that results in the progres-sive death of motor neurons, leading to paralysis and eventual death. There is presently no cure for ALS, and only two drugs are available, neither of which provide significant extension of life. The wide variation in onset and progression of the disease, both in sporadic and even in strongly penetrant monogenic famil-ial forms of ALS, indicate that in addition to background genetic variation impacting the disease process, environmental exposures are likely contributors. Epidemiological evidence worldwide implicates exposures to bacterial toxins, heavy metals, pesticides, and trauma as probable environmental factors. Here, we review current advances in gene-environment interactions in ALS animal models. We report our recent discov-eries in a zebrafish model of ALS in relation to exposure to the cyanobacterial toxin BMAA, and discuss several results from mouse models that show interactions with exposure to mercury and statin drugs, both leading to acceleration of the disease process. The increasing research into this combinatorial gene-environ-ment process is just starting, but shows early promise to uncover the underlying biochemical pathways that instigate the initial motor neuron defects and lead to their rapidly progressive dysfunction.

    Recently, wearable electronic devices including electrical sensors, flexible displays, and health monitors have received considerable attention and experienced rapid progress. Wearable supercapacitors attract tremendous attention mainly due to their high stability, low cost, fast charging/discharging, and high efficiency; properties that render them value for developing fully flexible devices. In this Concept, the recent achievements and advances made in flexible and wearable supercapacitors are presented, especially highlighting the promising performances of yarn/fiber-shaped and planar supercapacitors. On the basis of their working mechanism, electrode materials including carbon-based materials, metal oxide-based materials, and conductive polymers with an emphasis on the performance-optimization method are introduced. The latest representative techniques and active materials of recently developed supercapacitors with superior performance are summarized. Furthermore, the designs of 1D and 2D electrodes are discussed according to their electrically conductive supporting materials. Finally, conclusions, challenges, and perspective in optimizing and developing the electrochemical performance and function of wearable supercapacitors for their practical utility are addressed. © 2017 WILEY-VCH Verlag GmbH & Co.

    2011-01-01

    Full Text Available Over 50 years, several scientists and industries have developed new alternatives for wastewater treatment and remediation. Recently, electrochemical technology has been largely developed mainly because of its versatility and environmental compatibility. Scientific contributions about role of the electrode material have allowed determining that the influence of material in the selectivity is an important parameter. However, to interpret this behavior, comprehensive physical chemistry models for organics destruction, related to electrochemical phenomena and material surfaces, were proposed in the last decades. So, this paper presents a critical and comprehensive review about the principles and recent mechanism advances in electrocatalysis for wastewater treatment.

    1990-01-01

    More than two decades of magnetospheric exploration have led to a reasonably clear morphological picture of geomagnetic substorms, which is often summarized in terms of the near-Earth neutral line (NENL) model of substorms. Although this qualitative theory is quite comprehensive and explains a great many observations, it is hard pressed to explain both recent observations of consistently earthward flow within 19 R E and also the prompt onset of magnetic turbulence at 8 R E at the time of substorm onset. Other theories have recently been proposed which tend to be more quantitative, but which explain a more limited number of substorm observations. The challenge seems to be to understand the essential physics of these various quantitative theories and integrate them into a large structure such as is provided by the near-Earth neutral line model.

    Different metals have been proposed for radiation blistering of metals. For example, for the formation of blisters on helium bombarded metal surfaces such models are based on the coalescence of gas bubbles and the build-up of excess gas pressure in the implant region, causing large enough stresses for the occurrence of plastic deformation of the surface regions; or the percolation of helium in the lattice; or the build-up of large, lateral stresses in the implant layer causing buckling. These models are critically reviewed in the light of recent experimental results. A discussion of blistering effects at high doses is included

    Lazopoulos, Konstantinos A.; Lazopoulos, Anastasios K.

    2017-04-01

    Basic fluid mechanics equations are studied and revised under the prism of fractional continuum mechanics (FCM), a very promising research field that satisfies both experimental and theoretical demands. The geometry of the fractional differential has been clarified corrected and the geometry of the fractional tangent spaces of a manifold has been studied in Lazopoulos and Lazopoulos (Lazopoulos KA, Lazopoulos AK. Progr. Fract. Differ. Appl. 2016, 2, 85-104), providing the bases of the missing fractional differential geometry. Therefore, a lot can be contributed to fractional hydrodynamics: the basic fractional fluid equations (Navier Stokes, Euler and Bernoulli) are derived and fractional Darcy's flow in porous media is studied.

  16. An aerodynamic analysis of recent FIFA world cup balls

    Science.gov (United States)

    Kiratidis, Adrian L.; Leinweber, Derek B.

    2018-05-01

    Drag and lift coefficients of recent FIFA world cup balls are examined. We fit a novel functional form to drag coefficient curves and in the absence of empirical data provide estimates of lift coefficient behaviour via a consideration of the physics of the boundary layer. Differences in both these coefficients for recent balls, which result from surface texture modification, can significantly alter trajectories. Numerical simulations are used to quantify the effect these changes have on the flight paths of various balls. Altitude and temperature variations at recent world cup events are also discussed. We conclude by quantifying the influence these variations have on the three most recent world cup balls, the Brazuca, the Jabulani and the Teamgeist. While our paper presents findings of interest to the professional sports scientist, it remains accessible to students at the undergraduate level.

    Noise pollution from hydraulic equipments (bath filling, toilets taps, waste waters flow, vibrations, knocks in water pipes, dilatation clattering in heating pipes, hissing of heater taps etc..) are one of the principal causes of nuisance inside residential buildings. Solutions exist and consist in the replacement of old cocks and fittings, the use of soundproof clamps for pipes and noise absorbing supports for baths etc.. This paper summarizes the available modern equipments with a low-noise warranty (cocks and fittings, noise dampers, anti-backflow valves, pressure reducers) and the practical solutions for the modification of existing installations (increase of pipe diameters, reduction of pipe lengths, use of flexible fittings, hydraulic counterbalancing of water flows in heaters etc..).

    Small hydro is a renewable source of energy that is economically and technically viable. This article described China's investment in small-scale hydroelectric power plants in 1,600 remote communities. Seventy per cent of China's small hydro power stations are concentrated in remote impoverished communities. These power stations provide electricity to 300 million people in China, where half of the territories, one third of the districts and towns, and one quarter of the population depend primarily on this energy source for their electricity needs. The first power station was built in the province of Yunnan in 1912, but the real development of small hydro occurred after 1950, and can be divided into three phases. Phase 1 occurred before 1980 when small hydro power stations concentrated on providing electricity for lighting in rural areas as well as for transforming agriculture and irrigation. For many decades following the foundation of the Republic of China, rural areas did not have access to electricity or had serious shortages of electricity. In order to ensure electricity in isolated and remote areas, the Chinese government requested that local authorities build and exploit small hydro where conditions were favourable, and this while respecting water resources. Phase 2 occurred between 1980s and 1990s, with a focus on improving the performance of small hydro power stations to include electricity provisions for local enterprises. During phase 2, small hydro became a tool for dynamic rural development for farmers to increase their revenues. The latest phase in small hydro development has also helped reduce poverty and develop local economies, but in addition, it plays a role in the long term protection of ecosystems, the environment and rural modernization. Today 660,000 people work for small power stations and most are employed locally. Replacing firewood with electricity has saved 130,000 hectares of forested land and helped protect ecosystems. Small hydro has helped in reducing 100 million tons of carbon dioxide emissions. 5 refs., 2 figs.

  13. Recent Advances in Bioprinting and Applications for Biosensing

    Directory of Open Access Journals (Sweden)

    Andrew D. Dias

    2014-04-01

    Full Text Available Future biosensing applications will require high performance, including real-time monitoring of physiological events, incorporation of biosensors into feedback-based devices, detection of toxins, and advanced diagnostics. Such functionality will necessitate biosensors with increased sensitivity, specificity, and throughput, as well as the ability to simultaneously detect multiple analytes. While these demands have yet to be fully realized, recent advances in biofabrication may allow sensors to achieve the high spatial sensitivity required, and bring us closer to achieving devices with these capabilities. To this end, we review recent advances in biofabrication techniques that may enable cutting-edge biosensors. In particular, we focus on bioprinting techniques (e.g., microcontact printing, inkjet printing, and laser direct-write that may prove pivotal to biosensor fabrication and scaling. Recent biosensors have employed these fabrication techniques with success, and further development may enable higher performance, including multiplexing multiple analytes or cell types within a single biosensor. We also review recent advances in 3D bioprinting, and explore their potential to create biosensors with live cells encapsulated in 3D microenvironments. Such advances in biofabrication will expand biosensor utility and availability, with impact realized in many interdisciplinary fields, as well as in the clinic.

    2015-01-01

    Dengue represents an increasingly important public health challenge in Puerto Rico, with recent epidemics in 2007, 2010, and 2012–2013. Although recent advances in dengue vaccine development offer hope for primary prevention, the role of health professionals in the diagnosis and management of dengue patients is paramount. Case definitions for dengue, dengue with warning signs, and severe dengue provide a framework to guide clinical decision-making. Furthermore, the differentiation between dengue and other acute febrile illnesses, such as leptospirosis and chikungunya, is necessary for the appropriate diagnosis and management of cases. An understanding of dengue epidemiology and surveillance in Puerto Rico provides context for clinicians in epidemic and non-epidemic periods. This review aims to improve health professionals’ ability to diagnose dengue, and as highlight the relevance of recent advances in dengue prevention and management in Puerto Rico. PMID:26061055

    The new inflationary universe scenario is, in principle, a simple and powerful approach to resolving a large number of fundamental cosmological problems. However, in order for the scenario to be considered a complete theory, one critical question remains to be answered: What is the physics responsible for the phase transition that triggers the exponential expansion (inflation) of the universe? One possibility that the authors and several other groups have been pursuing is that the physics responsible for the phase transition involves (local) supersymmetry. The goal of this paper is to review the present status of ''Supersymmetric Inflation'', particularly emphasizing some very exciting results that they recently obtained

    Energy Technology Data Exchange (ETDEWEB)

    Mandels, M; Sternberg, D

    1976-01-01

    Interest in studies of cellulase activities of micro-organisms has increased in recent years because it is hoped that such studies may contribute to the solution of some of our current pressing economic problems. Cellulose is the only organic material that is annually replenishable in very large quantities. The utilization of this resource is greatly simplified if cellulose is first hydrolyzed to its monomer, glucose. This conversion could be accomplished by either acid or enzymatic hydrolysis. When using acid, expensive corrosion proof equipment if required. Moreover, the crystalline structure of cellulose makes it very resistant to acid so that the temperature and acid concentration needed to achieve hydrolysis also cause decomposition of the resulting sugars so that yields of glucose are low and the syrups contain unwanted by-products and reversion compounds. The enzymes on the other hand are specific for cellulose and related polysaccharides and they do not react with impurities that may be present in waste cellulose. Moreover, the reaction takes place at moderate conditions so glucose is not degraded and enzymatically produced syrups are fairly pure and constant in composition. This paper is a review of the recent efforts at Natick to develop a practical process for enzymatic saccharification of waste cellulose and produce cheap technical glucose.

    2012-02-01

    Although there is a well-known link between adverse experiences and suicidal ideation, there has been little study of the effects of recent adverse experiences on suicidal ideation in teenagers. This study examined the association between recent adverse experiences and suicidal ideation in a sample of 740 at-risk 16-year-old youth in the LONGSCAN studies, as well as potential mediators. 8.9% of the youth reported suicidal ideation. Recent adverse experiences, as a class, were associated with suicidal ideation; both recent physical abuse and recent psychological maltreatment were uniquely associated with suicidal ideation. The links between recent adverse experiences and suicidal ideation were significantly mediated by psychological distress. There were also significant main effect associations between both internalizing behavioral problems and low positive achievement expectations and suicidal ideation. Recent adverse experiences are important in understanding suicidal ideation in high risk youth. Copyright © 2011 The Foundation for Professionals in Services for Adolescents.

The results presented include searches for stops and sbottoms, production of charginos and neutralinos, and R-parity violating signatures. Several of them are the first results of their kind from CMS, while others increased the mass reach significantly over previously published results from the LHC.

    Researchers and policymakers have in recent years paid considerable attention to the phenomenon of capital flight. Researchers have focused on four questions: What concept should be used to measure capital flight? What figure for capital flight will emerge, using this measure? Can the occurrence and magnitude of capital flight be explained by certain (economic) variables? What policy changes can be useful to reverse capital flight? The authors focus strictly on presenting estimates of capital...

    2013-01-01

    Purpose of review Parkinson disease is the second most common neurodegenerative disease after Alzheimer disease, and current demographic trends indicate a life-time risk approaching 4% and predict a doubling of prevalence by 2030. Strategies are being developed to apply recent advances in our understanding of the cause of Parkinson disease to the development of biomarkers that will enable the identification of at-risk individuals, enable early diagnosis and reflect the progression of disease. The latter will be particularly important for the testing of disease-modifying therapies. This review summarizes recent advances in Parkinson disease biomarker development. Recent findings Recent reports continue to reflect the application of a variety of clinical, imaging or biochemical measurements, alone or in combination, to general Parkinson disease populations. Probably the most promising is the assay of alpha-synuclein in the diagnosis and evolution of Parkinson disease. At present, detection techniques are still being refined, but once accurate and reproducible assays are available, it will be important to define the relationship of these to early diagnosis and progression. Alpha-synuclein concentrations may also be modulated by certain disease-modifying agents in development and so may represent a measure of their efficacy. It has to be accepted that no single measure currently fulfils all the necessary criteria for a biomarker in Parkinson disease, but combinations of measures are more likely to deliver benefit. Summary The Parkinson disease biomarker field is approaching a stage when certain combinations of clinical, imaging and biochemical measures may identify a proportion of individuals at risk for developing the disease. However, their general applicability may be limited. Attention is now turning to stratification of Parkinson disease into certain at-risk groups defined by genotype. The application of multimodal screening to these populations may be more

    Full Text Available Raoul Tibes, James M Bogenberger, Ruben A MesaDivision of Hematology and Oncology, Mayo Clinic, Scottsdale, AZ, USAAbstract: The myeloproliferative neoplasm of myelofibrosis (MF is clinically constituted by individuals both with primary MF, as well as those that evolved from an antecedent polycythemia vera or essential thrombocythemia. Individuals presenting with MF have a heterogeneous phenotype which can involve significant constitutional symptoms (night sweats, fevers, weight loss, fatigue, variable but frequently problematic splenomegaly, and multifactorial cytopenias. These individuals clearly have decreased survival. Refinement of MF prognostic scores can distinguish from survival as poor as 16 months, to a median survival of 185 months. Sadly, although curative, allogeneic stem cell transplant still has sobering success rates for individuals of the standard ages for MF. Recent reports suggest less than half of patients will be alive at 3 years after allotransplant above the age of 60 years. The most important recent advancement in MF therapy has been the development of Janus kinase 2 (JAK2 inhibitors led by ruxolitinib, now Food and Drug Administration approved in the United States, and several other JAK2 inhibitors (in testing including SAR302503, CYT387, and SB1518. In randomized, placebo-controlled studies, ruxolitinib was demonstrated to be superior for the improvement of splenomegaly and symptoms. These benefits are mirrored across other JAK2 inhibitors. Improving anemia remains an unmet need in MF and is currently being evaluated by clinical trials utilizing the JAK2 inhibitor CYT387, as well as pomalidomide. Additional areas of interest for MF therapy include the inhibition of histone/lysine deacetylases, hedgehog pathway inhibition, as well as combination strategies with JAK2 inhibitors.Keywords: myeloproliferative neoplasm, myelofibrosis, JAK2 inhibitors

    Ever since the discovery of parasitic inclusions in erythrocytes of cattle in Romania by Victor Babes at the end of the 19th century, newly recognised babesial pathogens continue to emerge around the world and the substantial public health impact of babesiosis on livestock and man is ongoing. Babesia are transmitted by ixodid ticks and infection of the host causes a host-mediated pathology and erythrocyte lysis, resulting in anemia, hyperbilirubinuria, hemoglobinuria, and possibly organ failure. Recently obtained molecular data, particularly for the 18S rRNA gene, has contributed significantly to a better understanding of the sometimes puzzling phylogenetic situation of the genus Babesia and new information has been added to help determine the taxonomic position of many species. Moreover, it seems that owing to higher medical awareness the number of reported cases in humans is rising steadily. Hitherto unknown zoonotic babesias are now being reported from geographical areas where babesiosis was not known to occur and the growing numbers of immunocompromised individuals suggest that the frequency of cases will continue to rise. This review covers recent insights into human babesiosis with regard to phylogeny, diagnostics and treatment in order to provide new information on well known as well as recently discovered parasites with zoonotic potential.

    2007-01-01

    The CEA's Aladin gamma imaging system has been operated successfully for several years in nuclear plants and during decommissioning projects with additional tools such as gamma spectrometry detectors and dose rate probes. The radiological information supplied by these devices is becoming increasingly useful for establishing robust and optimized decommissioning scenarios. Recent technical improvements allow this gamma imaging system to be operated in low-level applications and with shorter acquisition times suitable for decommissioning projects. The compact portable system can be used in places inaccessible to operators. It is quick and easy to implement, notably for onsite component characterization. Feasibility trials and in situ measurements were recently carried out under low-level conditions, mainly on waste packages and glove boxes for decommissioning projects. This paper describes recent low-level in situ applications. These characterization campaigns mainly concerned gamma emitters with γ energy < 700 keV. In many cases, the localization of hot spots by gamma camera was confirmed by additional measurements such as dose rate mapping and gamma spectrometry measurements. These complementary techniques associated with advanced calculation codes (MCNP, Mercure 6.2, Visiplan and Siren) offer a mobile and compact tool for specific assessment of waste packages and glove boxes.

    Full Text Available The identification of signals of very recent positive selection provides information about the adaptation of modern humans to local conditions. We report here on a genome-wide scan for signals of very recent positive selection in favor of variants that have not yet reached fixation. We describe a new analytical method for scanning single nucleotide polymorphism (SNP data for signals of recent selection, and apply this to data from the International HapMap Project. In all three continental groups we find widespread signals of recent positive selection. Most signals are region-specific, though a significant excess are shared across groups. Contrary to some earlier low resolution studies that suggested a paucity of recent selection in sub-Saharan Africans, we find that by some measures our strongest signals of selection are from the Yoruba population. Finally, since these signals indicate the existence of genetic variants that have substantially different fitnesses, they must indicate loci that are the source of significant phenotypic variation. Though the relevant phenotypes are generally not known, such loci should be of particular interest in mapping studies of complex traits. For this purpose we have developed a set of SNPs that can be used to tag the strongest approximately 250 signals of recent selection in each population.

    Some recent developments in the experimental search for neutrino mass are discussed. Simpson and Hime report finding new evidence for a 17-keV neutrino in the β decay of 3 H and 35 S. New data from Los Alamos on the electron neutrino mass as measured in tritium beta decay give an upper limit of 13.5 eV at the 95% confidence level. This result is not consistent with the long-standing ITEP result of 26(5) eV within a ''model-independent'' range of 17 to 40 eV. It now appears that the electron neutrino is not sufficiently massive to close the universe by itself. 38 refs., 1 figs., 2 tabs

    2015-09-01

    The tendency of bacterial cells to adhere and colonize a material surface leading to biofilm formation is a fundamental challenge underlying many different applications including microbial infections associated with biomedical devices and products. Although, bacterial attachment to surfaces has been extensively studied in the past, the effect of surface topography on bacteria-material interactions has received little attention until more recently. We review the recent progress in surface topography based approaches for engineering antibacterial surfaces. Biomimicry of antibacterial surfaces in nature is a popular strategy. Whereas earlier endeavors in the field aimed at minimizing cell attachment, more recent efforts have focused on developing bactericidal surfaces. However, not all such topography mediated bactericidal surfaces are necessarily cytocompatible thus underscoring the need for continued efforts for research in this area for developing antibacterial and yet cytocompatible surfaces for use in implantable biomedical applications. This mini-review provides a brief overview of the current strategies and challenges in the emerging field of topography mediated antibacterial surfaces.

    2014-11-01

    Full Text Available The micro/nano positioning field has made great progress towards enabling the advance of micro/nano technology. Micro/nano positioning stages actuated by piezoelectric actuators are the key devices in micro/nano manipulation. The control of piezoelectric actuators has emerged as a hot topic in recent years. Piezoelectric materials have inherent hysteresis and creep nonlinearity, which can reduce the accuracy of the manipulation, even causing the instability of the whole system. Remarkable efforts have been made to compensate for the nonlinearity of piezoelectric actuation through the mathematical modelling and control approaches. This paper provides a review of recent advances on the control of piezoelectric actuators. After a brief introduction of basic components of typical piezoelectric micro/nano positioning platforms, the working principle and modelling of piezoelectric actuators are outlined in this paper. This is followed with the major control method and recent progress is presented in detail. Finally, some open issues and future work on the control of piezoelectric actuators are extensively discussed.

    2018-01-01

    The heavy-ion program in the ATLAS experiment at the LHC originated as an extensive program to probe and characterize the hot, dense matter created in relativistic lead-lead collisions. In recent years, the program has also broadened to a detailed study of collective behavior in smaller systems. In particular, the techniques used to study larger systems are also applied to proton-proton and proton-lead collisions over a wide range of particle multiplicities, to try and understand the early-time dynamics which lead to similar flow-like features in all of the systems. Another recent development is a program studying ultra-peripheral collisions, which provide gamma-gamma and photonuclear processes over a wide range of CM energy, to probe the nuclear wavefunction. This talk presents a subset of the the most recent results from the ATLAS experiment based on Run 1 and Run 2 data, including measurements of collectivity over a wide range of collision systems, potential nPDF modifications — using electroweak bosons,...

    2015-01-01

    This paper concerns recent progress in the development of a multifunctional smart coating, based on microencapsulation, for the autonomous detection and control of corrosion. Microencapsulation has been validated and optimized to incorporate desired corrosion control functionalities, such as early corrosion detection and inhibition, through corrosion-initiated release of corrosion indicators and inhibitors, as well as self-healing agent release triggered by mechanical damage. While proof-of-concept results have been previously reported, more recent research and development efforts have concentrated on improving coating compatibility and synthesis procedure scalability, with a targeted goal of obtaining easily dispersible pigment-grade type microencapsulated materials. The recent progress has resulted in the development of pH-sensitive microparticles as a corrosion-triggered delivery system for corrosion indicators and inhibitors. The synthesis and early corrosion indication results obtained with coating formulations that incorporate these microparticles are reported. The early corrosion indicating results were obtained with color changing and with fluorescent indicators.

    1981-01-01

    Progress in nuclear medicine is achieved through advances in radiopharmaceuticals, improvement in instrumentation design and improvement in data processing (computer hard- and software). With the appearance of the sup(99m)Tc-labelled phosphates, a major step towards finding ideal bone seeking tracers was undertaken. The more recent modifications of these tracers have tended to offer only minor advantages over and above what has already been achieved, i.e., improved skeletal uptake and somewhat faster blood clearance characteristics. Whilst computer hard- and software is undergoing constant streamlining (more power, in lesser space, with greater economy), instrumentation designs have matured. All of these techniques have relied upon conventional planar imaging and only very recently have alternative apparatuses appeared. The issue at stake is whether some form of tomographic imaging may have a role to play in the investigation of the skeleton. Important and inherent advantages occur if one is able to reconstruct data into tomograms: data interpretation is performed with the benefit of depth information, contrast resolution permits the visualization of structures previously masked and computer analysis permits the measurement of tracer uptake within well-defined sections of the organ or segment to be investigated. In this review, the authors offer original data which may provide some pointers as to future areas of application of this new approach. (Auth.)

    This study is a contribution to the development of methodologies allowing to assess the radiological impact of liquid effluent releases from nuclear power plants. It first concerns hydrodynamics models and their applications to the North sea, which is of great interest to the European Community. Starting from basic equations of geophysical fluid mechanics, the assumptions made at each step in order to simplifly resolution are analysed and commented. The results published on the application of the Liege University models (NIHOUL, RONDAY et al.) are compared to observations both on tides and tempests and residual circulation which is responsible for the long-terme transport of pollutants. The results for residual circulation compare satisfactorily, and the expected accuracy of the other models is indicated. A dispersion model by the same authors is then studied with a numerical integration method using a moving grid. Others models (Laboratoire National d'Hydraulique, EDF) used for the Channel, are also presented [fr

Aucune alose ne s'engage dans la passe quand la vitesse moyenne y excède 1,5 m/s. L'inefficacité de ce dispositif de franchissement s'explique par son manque d'attractivité et ses caractéristiques hydrauliques inadéquates, compte tenu des faibles capacités de nage des aloses.

  11. PET/MRI: Technical challenges and recent advances

    International Nuclear Information System (INIS)

    Jung, Jin Ho; Choi, Yong; Im, Ki Chun

    2016-01-01

    Integrated positron emission tomography (PET)/magnetic resonance imaging (MRI), which can provide complementary functional and anatomical information about a specific organ or body system at the molecular level, has become a powerful imaging modality to understand the molecular biology details, disease mechanisms, and pharmacokinetics in animals and humans. Although the first experiment on the PET/MRI was performed in the early 1990s, its clinical application was accomplished in recent years because there were various technical challenges in integrating PET and MRI in a single system with minimum mutual interference between PET and MRI. This paper presents the technical challenges and recent advances in combining PET and MRI along with several approaches for improving PET image quality of the PET/MRI hybrid imaging system

    This paper reviews the historical data on patenting in the United States with special reference to the last 20 years and their potential relation, if any, to the recent productivity slowdown. Two Points are made: Patents are not a "constant-yardstick" indicator of either inventive input or output. Moreover, they are "produced" by a governmental agency which goes through its own budgetary and inefficiency cycles. The paper shows that the appearance of an absolute decline in patenting in the 19...

    Recent reports have suggested that the attended features of an item may be rapidly forgotten once they are no longer relevant for an ongoing task (attribute amnesia). This finding relies on a surprise memory procedure that places high demands on declarative memory. We used intertrial priming to examine whether the representation of an item's…

  19. Recent top physics results from CMS

    CERN Multimedia

    CERN. Geneva

    2014-01-01

    The top quark, discovered in 1995 at the Tevatron, is the heaviest known elementary particle. The largeness of its mass gives rise to a number of peculiar properties: top quarks decay before they would hadronize and the measurement of their decay products provides direct access to its properties such as spin, charge, or polarization. The top quark couples most strongly with the Higgs boson, and plays a key role in the electro-weak symmetry breaking and in many scenarios of physics beyond the Standard Model. With its large center-of-mass energy and luminosity, the LHC produces top quarks in copious quantities, giving access to many new precision measurements. In this seminar, I will present recent measurements from the CMS experiment. I will focus in particular on the results on single-top quark production, where results are available in all production modes, the t-, the s- and the tW-channels. Furthermore, I will present recent measurements of top quark properties as well as searches for anomalous couplings ...
