In numerical simulations, it is always necessary to find an optimum between the simplicity of the model and a good representation of real phenomena. In the field of hydraulic flows simulations, the models using depth-averaged and moment equations are an interesting compromise between full 3D and simple depth-averaged models. This paper presents the use of a moment equation for suspended load transport. A simple but representative model for the sediment concentration profiles is developed. This original bi-linear concentration profile is compared to the traditional Rouse-profiles and shows a good correspondence despite its great simplicity. Advective and diffusive sediment fluxes are developed analytically and lead to a concise formulation, which is an asset for practical use. A differential equation for the sediment concentration moment is also fully developed, and a special attention is cast to the source term. The finite volume scheme has been chosen to implement the model, because it is particularly well suited for highly advective transport equations, it is conservative and it makes the choice of the upwinding easier. 1D simulations show the capacity of the model to reproduce laboratory experiments described in the literature.

Pulmonary arterial hypertension (PAH) results from persistent vasoconstriction, smooth muscle growth and extracellular matrix (ECM) remodelling of pulmonary arteries (PAs). Matrix metalloproteinases (MMPs) are matrix-degrading enzymes involved in ECM turnover, and in smooth muscle cell (SMC) and endothelial cell migration and proliferation. MMP expression and activity are increased in experimental PAH. Therefore, this study investigated whether similar changes occur in idiopathic PAH (IPAH; formerly known as primary pulmonary hypertension). Both in situ and in vitro studies were performed on PAs from patients undergoing lung transplantation for IPAH and from patients treated by lobectomy for localised lung cancer, who served as controls. In IPAH, MMP–tissue inhibitor of metalloproteinase (TIMP) imbalance was found in cultured PASMCs, with increased TIMP-1 and decreased MMP-3. MMP-2 activity was markedly elevated as a result of increases in both total MMP-2 and proportion of active MMP-2. In situ zymography and immunolocalisation showed that MMP-2 was associated with SMCs and elastic fibres, and also confirmed the MMP-3–TIMP-1 imbalance. In conclusion, the findings of this study were consistent with a role for the matrix metalloproteinase–tissue inhibitor of metalloproteinase system in pulmonary vascular remodelling in idiopathic pulmonary arterial hypertension. The matrix metalloproteinase–tissue inhibitor of metalloproteinase imbalance may lead to matrix accumulation, and increased matrix metalloproteinase-2 activity may contribute to smooth muscle cell migration and proliferation. Whether these abnormalities are potential therapeutic targets deserves further investigation. [less ▲]

INTRODUCTION: In the present study we explored the role of cognitive factors in hallucinatory proneness by utilising an incidental source monitoring task consisting of actions. METHOD: A total of 65 normal subjects were administered a source monitoring task and were asked either to: (1) perform the action; (2) watch the experimenter perform the action; (3) imagine him/herself performing the action; (4) imagine the experimenter performing the action; (5) or listen to the experimenter say the action verbally. Following a delay, actions were presented consisting of those already presented in one of the 5 conditions (old), and those never before presented (new). For each action, subjects were required to identify if the action was old or new. If the action was identified as old, subjects were required to identify the source of the word (i.e., one of the 5 conditions). Subjects also completed a questionnaire assessing metacognitive beliefs. Subjects were grouped according to their scores on a revised and elaborated version of the Launay-Slade Hallucinations Scale (LSHS). Those with scores within the top 25% were included in the hallucination-prone group (HP) (n = 16), whereas scores within the lower 25% were included in the nonhallucination-prone group (NHP) (n = 16). RESULTS: Within the internal conditions, hallucination-prone subjects confused two internal sources (a specific internal-internal source discrimination error). That is, for imagined actions where the subjects performed the action, HP subjects erroneously attributed these towards an imagined action performed by the experimenter. Results also revealed that hallucination-proneness was associated with metacognitive beliefs. Finally, there was a significant relation between certain metacognitive beliefs and the internal-internal source discrimination error on the source monitoring task. CONCLUSIONS: Findings from the present study suggest that an important cognitive deficit in the genesis of hallucinations may be a perturbation in the control of interna [less ▲]

The etiological mechanisms of brain edema in fulminant hepatic failure are incompletely understood. In a surgical model of fulminant hepatic failure in the rat, we tested whether oxidative stress may be involved in the early steps of brain edema. Moreover, we took advantage of this model to determine if oxidative stress may be involved in the hepatocyte dysfunction observed in the setting of fulminant hepatic failure. Oxidative stress was evaluated by measurement of tissue ascorbic acid in the brain and liver of rats at 6 hours after induction of fulminant hepatic failure versus in control or partially hepatectomized rats. After 6 hours, the level of ascorbic acid was not different in the brain tissue of the various groups, indicating no oxidative stress. The liver showed a significant decrease in ascorbic acid levels, both in ischemic and nonischemic liver tissue, suggesting that oxidative stress might be involved in the failure of liver regeneration in fulminant hepatic failure. In this rat model no oxidative stress was demonstrated in the brain during the early phase of fulminant liver failure. [less ▲]

High-speed steels (HSSJ rofis are useci in front finishing stands of hot strip mils. Good wear resistance and hardness at high temperature are defining features of HSS. Many types of carbides are present in these alloys, each having different effect upon the final properties of HSS. As a resuit, nature, morphology and amount of these carbides are factors of important concern. Identification and characterisation of HSS carbides are realised with optical microscopy comhined with electron microscopy. [less ▲]

Le cours d’Histoire de l’art de l’époque contemporaine (I et II) s’adresse à des étudiants ayant une connaissance préalable des mouvements artistiques qui jalonnent les XIXe et XXe siècles (cf. cours de 1er bac). Donné de manière « cyclique », le cours se divise en deux grandes parties : une première est consacrée au mouvement d’intérêt suscité par l’art japonais dans la seconde moitié du XIXe siècle et à ses prolongements après 1945 ; une seconde partie traite de problématiques variées liées à la création artistique depuis 1960 jusqu’à nos jours et consacre également une partie du cours à l’histoire de la photographie. De manière générale, ce cours a pour objectif de fournir à la fois les données historiques, stylistiques et tout éclairage (d'ordre philosophique, sociologique, politique, économique, scientifique, littéraire...) utiles à une compréhension plus approfondie des formes d'expressions plastiques de l’art moderne et contemporain.

The analysis of risk of flood downstream from the hydroelectric dam of Nangbeto in the Mono River was about the survey of interannual variability of rainfall and rivers flows from 1955 to 1999, the population vulnerability, the hydrological modification and the impacts downstream in Togo and Benin from the dam constructed in 1987. The analysis of the mean annuel discharge has revealed no tendency, showing thus that the change of land use, the increase of waterproof areas and even the functioning of the hydroelectric dam have not modified in a significant manner the river's rate of flow. Apart from the return to the improvement in rainfull as far back as the end of years 80, the anthropic pressure and the demographic explosion have best explained the magnitude and frequency of flooding downstream from the hydroelectric dam of Nangbeto. The soil degradation, the deforestation of the floodplain, the increase in the number of human settlements in the river boundary increases the vulnerability of population faced with flooding.

The SAPPHIRE trial compared the results of carotid endarteriectomy to those of carotid artery stenting with an emboli-protection device in patients with carotid artery stenosis and coexisting conditions that potentially increased the risk posed by endarteriectomy. The trial concluded that stenting was not inferior to endarteriectomy. This publication was selected by the AHA among the "Top Ten of Heart Disease and Stroke Research" for 2004. Yet, from the start, it raised a considerable controversy which was already exposed in the Editorial which appeared in the same issue of the NEJM. The present paper analyses and summarizes the various potential bias which raised suspicion regarding the SAPPHIRE data. It also underlines the fact that the results obtained in the SAPPHIRE surgical series are considerably inferior to those generally cited in the literature, or those obtained locally. [less ▲]
