BACKGROUND The high numbers of heterotrophic microorganisms that have been cultured from dental unit waterlines (DUWs) have raised concern that this water may exceed suggested limits for heterotrophic plate counts (HPCs). The main purpose of this investigation was to examine HPC variability in DUWs and to examine in detail the effect of laboratory processing of water samples on HPC values. ME...

mhd boundary layer flow of two phase model nanofluid over a vertical plate is investigated both analytically and numerically. a system of governing nonlinear partial differential equations is converted into a set of nonlinear ordinary differential equations by suitable similarity transformations and then solved analytically using homotopy analysis method and numerically by the fourth order rung...

Experimental validation and testing of solutions designed for heterogeneous environment is a challenging issue. Wrekavoc is a tool for performing such validation. It runs an unmodified applications on emulated multisite heterogeneous platforms. It downgrades the performance of the nodes (CPU and memory) and the interconnection network in a prescribed way. We report on new strategies to improve ...

Né d’un besoin logiciel pour une étude de cohorte [1], CORON est maintenant une plate-forme logicielle d’extraction de connaissances à part entière, utilisée dans divers domaines, voir par exemple [4, 5, 6]. Destinée à un usage scientifique et pédagogique, la plate-forme CORON s’articule autour de plusieurs modules pour la préparation puis la fouille de données, le filtrage et l’interprétation ...

The aim of this paper is to show that, for a linear second-order hyperbolic equation discretized by the backward Euler scheme in time and continuous piecewise linear finite elements in space, the adaptation of the time steps can be combined with spatial mesh adaptivity in an optimal way. We derive a priori and a posteriori error estimates which admit, as much as it is possible, the decoupling o...

* This study would not have been possible without the financial support of the Fondation Universitaire pour la Coopération Internationale au Développement (FUCID) and the Centre de Recherche en Economie du Développement (CRED), both at the university of Namur. This support is gratefully acknowledged as well as the collaboration of partner institutions in Senegal, the Centre de Recherche et de D...

risk of microbial contamination in the cosmetic products and transmission to consumers especially in smuggled preparations is very high. according in this study, the microbial content and pollution some of the sunscreen creams in the market and one sample in official market as witness were evaluated. the microbial content (bacterial total count, fungal count, and presence of pseudomon asaerogin...

Six selective media, namely xylose lysine desoxycholate agar (XLD), desoxycholate citrate agar (DCA), desoxycholate citrate lactose saccharose agar (DCLS), Salmonella Shigella agar (SS), bismuth sulphiteagar (BS) and brilliant green agar (BG), were compared for recovering Salmonella from pure cultures using the pour plate method. BS agar was superior to alt-the other agars in supporting growth ...
