Staphylococcus aureus is the second leading pathogenic cause of nosocomial infections and plays an important role in development food poisoning purulent, systemic infections. This bacterium responsible for such as abscess, poisoning, third grade burns, traumatic ulcers, surgical incisions, bed sores or atrophic ulcers. Long-term use antibiotics has led to emergence multi-drug resistant strains ...

BACKGROUND Descurainia sophia seeds have a variety of pharmacological functions and been widely used in traditional folk medicine. However, their effects on human drug metabolizing enzyme (DME) activities have not been elucidated. The present study investigated the inhibitory effects of an ethanol extract of D. sophia seeds (EEDS) on human Phase I/II (DMEs) and P-glycoprotein (p-gp) in vitro. ...

Persistence provides a way of grading the importance of homological features in the sublevel sets of a real-valued function. Following the de nition given by Edelsbrunner, Morozov and Pascucci, an ε-simpli cation of a function f is a function g in which the homological noise of persistence less than ε has been removed. In this paper, we give an algorithm for constructing an ε-simpli cation of a...

The ability to quickly evaluate network protocols or infrastructure shapes on real-life scale simulations is a key factor for network researchers work. Since multi-core systems are now widely available and installed, doing multithreading parallelism is a simple but potentially efficient optimization for simulators performance, which may also be implemented so that the parallelism is completely ...

We describe here some recent developments in mesh adaption for compressible viscous inviscid ow simulation. One of the most challenging task is to capture eeciently thin layers such as boundary layers, mixing layers. Two important issues, the coupling between mesh and ow, and the use of at elements for stretching are considered in the case of deformation mesh systems. RESUME : On pr esente une ...

A 50-yr study at Fairbanks, AK, was started in 1984 to determine soil seed longevity of 17 weed species. Seeds were buried in mesh bags 2and 15-cm deep and were recovered 0.7, 1.7, 2.7, 3.7, 4.7, 6.7, 9.7, 19.7, and 24.7 yr later. Viability was determined using germination and tetrazolium tests. By 24.7 yr after burial (YAB), no viable seeds were found for common hempnettle, flixweed, foxtail b...
