meteorological radars estimate the precipitation using a reflection-precipitation relation as z=arb with a, b coefficients. these coefficients will change from one precipitation to the other one. for the tehran radars they are considered as a=200 and b=1.6. these values are proper when we have moderate precipitations. this assumption causes an error in the estimation of different precipitation ...

The effects of various macrolide antibiotics [triacetyloleandomycin (TAO), clarithromycin, azithromycin, roxithromycin, erythromycin base] and the new ketolide HMR3004 on CYP3A expression were evaluated in human and rat hepatocytes. Cells were treated for 3 days with nontoxic concentrations of the drugs, and CYP3A induction was assessed through midazolam hydroxylase activity and Western and Nor...

lead as non-essential metal, is known the source of toxicity and impacts on the environment and humans. the goal of recent paper is to determine the pb concentration of road and road margin dust of ghamishlu wildlife refuge in isfahan province with an area about 120,000 hectares surrounded by four main roads. traffic load in the southern freeway have been reported as about 3600-19000 cars/day. ...

The problem of finding straight-line drawings for planar graphs with small area is an important aspect in the context of drawing planar graphs and it has been extensively studied. In this thesis we will study the problem of finding planar straight-line grid drawings with minimum area. Our contributions to this problem are as follows: First, we will show, that the problem of finding minimum area...

87 Realizing the health-related sustainable development goals (SDGs) requires integrated action on system-wide challenges. To address gaps in health service delivery, we need evidence on which government agencies, research institutions, donors and civil society can act.1 Unless research is relevant to specific health systems, the evidence that it generates can be dismissed by policy-makers.2 Fo...

Industrial organizations continuously seek to apply the foundations of total production planning strategies because its positive role in helping these determine quantity required meet market demand presence crises and challenges such as epidemics natural disasters, well accurately determining organization's needs workers, time storage. Without an increase that, this contributes organization red...
