Background & Aims of the Study: The current study was designed to determine the quality of sediments in Karun in Ahvaz, Iran, according to aquatic pollution indices. Materials and Methods: The sediment samples were obtained from six river stations in summer and winter. The sediment samples were air-dried, sifted, homogenized, and stored in plastic bags, and the concentrations of metals were...

background: a cross-sectional analytic method was used to assess health and safety risks that really matter in restaurants of universities and hospitals in the gaza strip, palestine.  materials and methods: a 40-item questionnaire was completed by workers in all university and governmental hospital restaurants in the gaza strip. another 30-item questionnaire was completed by university students...

I N T R O D U C T I O N Pharmacological data were among the evidence which led to the view that the over-all electrophysiological manifestations of different excitable membranes are composites of a number of independently assorting electrogenic processes (Grundfest, 1961 a, b). Subsequently available data (cf. Grundfest, 1963, 1966 a, b) have reenforced this view, that the excitable membrane is a

A Primer on Mathematical Models in Biology Lee A. Segel and Leah Edelstein-Keshet This textbook grew out of a course that the popular and highly respected applied mathematician Lee Segel taught. It introduces differential equations, biological applications, and simulations and emphasizes molecular events, excitable systems, and small protein and genetic circuits. It is intended for upper-level ...

This paper proposes the Intra Trustcenter Protocol (ITP), a flexible and secure management protocol for communication between arbitrary trustcenter components. Unlike other existing protocols (like PKCS#7, CMP or XKMS) ITP focuses on the communication within a trustcenter. It is powerful enough for transferring complex messages which are machine and human readable and easy to understand. In add...

PURPOSE The estimated microbial contamination rate for complex, multiple-step, medium-risk-level compounding was studied. METHODS The results of evaluations of the aseptic technique of pharmacists and technicians in compounding complex USP medium-risk-level sterile preparations were compiled to estimate the microbial contamination rate. The testing took place in 2002 and 2003 at a single inst...

risk assessment provides the possibility of planning and management to prevent and reduce the risk of desertification. the present study is aimed to assess the hazard and risk of desertification and to develop management programs in the semi-arid western regions of golestan province in iran. desertification rate was obtained using the iranian model of desertification potential assessment. since...

Findings on dietary glycaemic index (GI) and glycaemic load (GL) as risk factors for type 2 diabetes have been controversial. We examined the associations of dietary GI and GL and the associations of substitution of lower-GI carbohydrates for higher-GI carbohydrates with diabetes risk in a cohort of Finnish men. The cohort consisted of 25 943 male smokers aged 50-69 years. Diet was assessed, at...
