We study quantum transport of an interacting Bose-Einstein condensate in a two-dimensional disorder potential. In the limit of a vanishing atom-atom interaction, a sharp cone in the angle-resolved density of the scattered matter wave is observed, arising from constructive interference between amplitudes propagating along reversed scattering paths. Weak interaction transforms this coherent backscattering peak into a pronounced dip, indicating destructive instead of constructive interference. We reproduce this result, obtained from the numerical integration of the Gross-Pitaevskii equation, by a diagrammatic theory of weak localization in the presence of nonlinearity. [less ▲]

Although low bone mineral density (BMD) is predictive of fracture risk in untreated patients, there is currently debate about the extent to which the antifracture efficacy of antiosteoporotic agents is related to BMD changes. The goal of this article is to make an overview of studies dealing with the association between BMD changes and fracture risk reduction. The percent- age of the reduction in fracture risk attributable to changes in BMD after an- tiresorptive treatments (risedronate, alendronate, and raloxifene) varies from 4% to 28%. One study with a bone-forming agent (teriparatide) found that the proportion of fracture risk reduction attributable to the increase in BMD ranged from 30% to 41%. With strontium ranelate, the changes in femoral neck and total hip BMD explained 76% and 74%, respectively, of the reduction in verte- bral fractures observed during treatment. However, study designs as well as statistical methods often differ, making the comparison between studies rather difficult. Our review indicates that the association between BMD changes and fracture risk is equivocal, but seems to be higher for strontium ranelate than that reported for its competitors. [less ▲]

The RS-PDM© model generates flows in time series on the basis of observed rainfall after self-calibration which is based on short period of observed rainfall and flow. This is done with daily or hourly data. The study highlights the capacity of the RS-PDM© model to simulate extreme flows in poorly gauged basins in Walloon region on the basis of observed rains and of a short period of observed flows. Concerning the time series, it was highlighted an important dispersion of the flows simulated for a given observed flow even for daily or hourly data. The Nash criteria varied between 0.59 and 0.92. However, the flows simulated via RS-PDM© make it possible to adjust a statistical distribution of extremes flows (Gumbel law) close to the statistic obtained with a long period of gauging. So, if the simulations realized by mean of this model present poor to acceptable performances concerning the time series simulations, they permit to obtain rapidly quite good statistics of extremes flows on the basis of a short gauging period.

BACKGROUND: In recent years, several studies showed increased rates of hyperglycaemia, diabetes, dyslipidemia, metabolic syndrome as well as cardiovascular disease in schizophrenic patients. The underlying mechanism, however, is poorly understood. Adiponectin is a recently identified adipocyte-derived protein, with low adiponectin levels being associated with metabolic abnormalities such as obesity, insulin resistance and type 2 diabetes. METHODS: Fasting adiponectin levels were assessed in a cross-sectional sample of 386 patients with schizophrenia or schizoaffective disorder. All patients were on monotherapy of second-generation antipsychotics (SGA) and underwent an extensive metabolic screening including an oral glucose tolerance test (OGTT). RESULTS: Adiponectin plasma levels were inversely correlated with BMI, and differed significantly between patients with normal weight, overweight or obesity (p<0.05). Patients who met criteria for the metabolic syndrome, according to adapted National Cholesterol Educational Program - Adult Treatment Panel criteria (NCEP-ATP III) (29.3%), had significantly lower adiponectin levels than patients not meeting metabolic syndrome criteria (p<0.0001). Patients without glucose abnormalities (78%) had significantly higher adiponectin levels than patients with diabetes (5.7%) (p<0.05). After controlling for components of metabolic syndrome and sex, antipsychotic medication independently influenced adiponectin levels (p<0.0001), with the lowest mean levels in patients on clozapine and olanzapine. CONCLUSIONS: Adiponectin levels in schizophrenic patients mirror what is observed in the general population, with the lowest levels in the most metabolically comprised subjects. However, antipsychotic medication may also influence adiponectin regulation independently, a finding that should be confirmed in longitudinal studies. [less ▲]

The quality valuation of wheat is based on characteristics like yield, specific weight, protein content and protein quality. Until now. the starch properties are rarely considered as a quality criterion. In this study, we showed the influence of wheat cultivars (Triticum aestivum L.) and culture year on the intrinsic properties of starch, extracted from European wheat grown in the same conditions. For example, starch damage varied from 13.2 to 19.9 CDU in function of the cultivars and contribution of the B-type starch granules (<10 mu m) to the total volume ranged from 11.6% to 29.9%. Starch viscosity at 95 degrees C, characterized with alpha-amylase inactivation by 2 mM AgNO3 addition. varied from 276.5 to 351.5 BU with the wheat cultivars. It is apparent from this study that starch properties were principally influenced by the wheat cultivar and slightly by the culture year. A good relationship between the pasting properties of whole flour and starch were finally established, showing the important role of starch in the whole flour viscosity. A thorough working knowledge of starch properties could lead to an appropriate selection of wheat cultivar, well-adapted to industrial end uses, without encountering processing or end-products quality problems and with most cost-competitive production.

Aias, herausragender griechischer Heros vor Troia, metzelt im Zustand der Raserei Herdenvieh nieder, in dem er seine Gegner zu erkennen glaubt. Zur Besinnung gekommen, stürzt er sich, beschämt über den Ehrverlust, in sein Schwert. Die ‚Entschuldigung‘, die für Aias nur durch Entleibung zu leisten war, entspricht heute etwa dem medial inszenierten Rückzug aus der politischen Öffentlichkeit, dem Rücktrittsangebot oder dem Fehlereingeständnis. Offensichtlich gibt es nach wie vor ein kollektives Bedürfnis nach solchen stellvertretenden Reinigungsritualen. Anlässe und Reaktionsformen haben sich zwar gewandelt, das Gefühl der Scham aber ist immer noch von existenziell-individueller Bedeutung und besitzt eine öffentlich wirksame Symbolik. Historisch gesehen spannt der Band einen Bogen von der (laut Georg Wilhelm Friedrich Hegel) ‚gewissenlosen‘ griechischen Antike bis in die ‚unverschämte‘ Gegenwart. Systematisch betrachtet konfrontieren die unterschiedlichen Kulturkreise einander in ihren Definitionen und Kompensationen von Fehlverhalten: vom paganen Griechentum über das christliche Abendland bis hin zum Islam. Im 20. und 21. Jahrhundert bestimmen Diskurse der Bewältigung den Umgang mit der Geschichte, mit Fragen der Kriegsschuld oder des Völkermordes. Kulturelle, nationale, historische und gender-spezifische Unterschiede prägen die verbalen Entschuldigungen, das öffentliche und private Verhalten, Kleidercode und Körpersprache. Während Schamdiskurse dazu dienen, eigenes Fehlverhalten in der Gemeinschaft zu regulieren oder vor dem Selbst zu rechtfertigen, funktionieren umgekehrt Schuldzuschreibungen oder gezielte Beschämungen des anderen als Herrschaftsinstrumente: prominent etwa in den Bildern von Abu Ghraib.

La description et la compréhension des conflits extrêmes ou « hyperconflits » constituent de nouvelles préoccupations en Psychologie du Travail et des Organisations. A partir de l’analyse des résultats de huit focus groups composés de professionnels du traitement des conflits, nous dégageons 24 indicateurs des hyperconflits. Plus généralement, il ressort de notre étude que ces situations sont liées à une réduction de la complexité du système organisationnel couplée à une généralisation de la dynamique conflictuelle du point de vue de l’espace-temps, des processus et des conséquences. Les implications en termes d’interventions sont également discutées. [less ▲]
