Dans cette thèse, nous nous intéressons à l'évaluation de performances des réseaux d'interconnexion multi-étages. Le travail présenté couvre deux aspects essentiels : la définition d'une méthodologie multi-critères pour l'évaluation et la comparaison de réseaux d'interconnexion. Cette méthodologie est basée sur la définition d'une fonction de distance dans un espace multidimension-nelle, où cha...

Physical CHEMISTRY INTRODUCTION The basis for any design and simulation of chemical and environmental systems is a reliable set of physical and chemical properties of reactants. Since it is not always possible to find experimental values in the literature as well as measurement is expensive and time consuming or sometimes even difficult or impossible, estimation methods are generally of great v...

background and objectives: cattle dermatophytosis (syn. cattle ringworm), an important skin infection, has received major consideration not only for economical losses in the animal breeding industry but also in regards to its zoonotic transmission to humans. for effective control measures, it is important to determine the disease prevalence in cattle herds. materials and methods: to determine r...

, fetal human oxytocin at birth is of fetal origin, because its concentrations are higher in the umbilical artery than in the umbilical vein, and oxytocin is completely absent in cord blood of anencephalic new-borns (Chard et al., 1971). Parturition is a very complex process and oxytocin has its role particularly in contractility of myocytes (Smith, 2007). Exogenous oxytocin administration to p...

I would like to thank Kimberly Farr...

Recent developments in formulations for generating swept volumes have made a significant impact on the efficiency of employing such algorithms and on the extent to which formulations can be used in representing complex shapes. In this paper, we outline a method for employing the representation of implicit surfaces using the Jacobian rank deficiency condition presented earlier for the sweep of p...

Background: The surgical management of liver injuries remains a great challenge for the traumatologists and general surgeons. We hypothesized that administration of 17 β-estradiol, a female sex hormone, improves hepatocellular healing after liver trauma. Methods: In an experimental model, 60 rats were divided into six subgroups: A (male control), B (male and estradiol), C (castrated male and es...

The Afghan resistance sees its struggle more in terms of a "holy war" (jihad) than as a war of national liberation. In a country in which reference to the "nation" is avery recent phenomenon, where the State is perceived as exterior to society and where allegiance belongs to the local community, Islam remains the sole point of reference for all Afghans. It is only in the southern Pushtun tribal...
