Bactericidal and Antibiotics synergistic effect of Nanosilver against Methicillin-Resistant staphylococcus aureus.
ABSTRACT BACKGROUND: Methicillin-Resistant _Staphylococcus aureus _(MRSA) are bacteria responsible for several difficult-to-treat infections in humans. These strains have developed, through the process of natural selection. Infections by MRSA are more difficult to treat with standard types of antibiotics and thus more dangerous to human health. OBJECTIVES: The aim of this study was to evaluate the bactericidal and antibiotic synergistic effect ... إقراء المزيد

A Novel Algorithm based on Entanglement Measurement for Improving Speed of Quantum Algorithms,
In this paper, we draw attention to consider that the quantum entanglement measurement should be implemented as a key part during manufacturing the quantum processors and quantum micro-controllers. This paper aims to harness the complete power of quantum mechanics by the crossover between entanglement measurements and quantum gates to propose a novel quantum computer algorithms and protocols. One of these ... إقراء المزيد

CIRCULATING VASCULAR  ENDOTHELIAL GROWTH FACTOR AND NITRIC OXIDE IN PATIENTS WITH LIVER CIRRHOSIS: A  POSSIBLE ASSOCIATION WITH LIVER FUNCTION IMPAIRMENT
Hemodynamic disorders of liver cirrhosis complicated with portal hypertension are associated with an increased angiogenesis in animal model of portal hypertension and cirrhosis which were linked to increased expression of vascular endothelial growth factor (VEGF) and nitric oxide (NO). The aim of study was to evaluate the serum concentration of VEGF and total nitric oxide (NO) in liver cirrhosis and ... إقراء المزيد

Chapter Title: Side Effects of Insecticides on Natural Enemies and Possibility of Their Integration in Plant Protection Strategies.
Recently, plant protection strategy has recommended, minimizing the use of chemical pesti11 cides. Therefore, studying the side effect of insecticides on the natural enemies is highly re12 quired to exclude the detrimental effects on the natural enemies. Every crop is infested by 13 various pests; some but not all of them may be controlled by biological means using patho14 gens, ... إقراء المزيد

A Coupled Random Fixed Point Result With Application in Polish Spaces
In this paper, we present a new concept of random contraction and prove a coupled random fixed point theorem under this condition which generalizes stochastic Banach contraction principle. Finally, we apply our contraction to obtain a solution of random nonlinear integral equations and we present a numerical example. إقراء المزيد

Morpho-Anatomical Characteristics of Olive (Olea europaea L.) Trees Leaf as Bio-indicator of Cement Dust Air Pollution in Libya
Comparisons were made between the anatomical and morphological changes in olive tree leaves from a site with relatively clean air (Al-Khadra area), and two sites (al-Khums and Zelatin) near to cement factories in the area east to Tripoli, Libya. Olive tree leaves exhibited marked variations in their morphological and anatomical characteristics, in relations to variations in the site cement dust ... إقراء المزيد
