the aim of this study was to determine the socioeconomic inequalities in nonuse of seatbelts in cars and helmets on motorcycles in kurdistan province, west of iran, 2009.the data used in this study was collected from the data gathered in non-communicable disease surveillance system (ncdss) in 2009 in kurdistan. a total of 1000 people were included in this study. the outcome variable of this stu...

porous silicon (ps) samples have been prepared by electrochemical anodization of p-type silicon wafer by varying hf concentrations in the electrolytic solution. the structural, surface morphological, optical and surface composition analysis of the prepared samples were done by x-ray diffraction (xrd), scanning electron microscopy (sem), photoluminescence (pl) and fourier transform infrared (fti...

Introduction: The present study investigated the relatively high concentrations of natural radionuclides in raw material that used in ceramic manufacturing, and estimated the occupational exposure due to these activity concentrations. Material and Methods: A high-purity Germanium detector was used to determine naturally occurring radionuclide...

in present study, it was determinated lc50 96-h and toxicity degree of diazinon in huso huso, then were evaluated effects of sub-lethal concentrations on tow general enzymatic indices including alanine and aspartate aminotransferase of plasma and one specific enzymatic index including tissue ache enzyme. the median lethal concentration, lowest observed effect concentration and maximum allowable...

This paper presents an adaptive version of the Hill estimator based on Lespki’s model selection method. This simple data-driven index selection method is shown to satisfy an oracle inequality and is checked to achieve the lower bound recently derived by Carpentier and Kim. In order to establish the oracle inequality, we derive non-asymptotic variance bounds and concentration inequalities for Hi...

background: sialic acid is a component of serum that is elevated in diseases such as diabetes and certain malignancies.  the normal range of ssa concentration and serum neuraminidase activity in different populations are varied, probably due to racial differences.   objective: the purpose of the present study was to obtain the average ssa concentration and serum neuraminidase activity, in an ir...

The concentration index is widely used to measure income-related inequality in health. No insight exists, however, whether the concentration index connects with people's preferences about distributions of income and health and whether a reduction in the concentration index reflects an increase in social welfare. We explored this question by testing the central assumption underlying the concentr...
