INTRODUCTION Food-borne infections and intoxications remain one of the most important public health issues globally, both in developing and in developed countries. Numbers of reported outbreaks of food-borne diseases and diseased people are constantly growing. For instance, a total of 320,000 of cases of food-borne diseases, caused by only 6 most prevalent bacterial pathogens (non-typhoidal Sal...

Background: One of the main causes of induction of secondary cancer in radiation therapy is neutron contamination received by patients during treatment.Objective: In the present study the impact of wedge and block on neutron contamination production is investigated. The evaluations are conducted for a 15 MV Siemens Primus linear accelerator. Methods: Simulations were performed using MCNPX Monte...

Trace metals (Cd, Cr, Cu, Ni and Pb) concentrations in benthic sediments were analyzed through multi-step fractionation scheme to assess the levels and sources of contamination in estuarine, riverine and freshwater ecosystems in Niger Delta (Nigeria). The degree of contamination was assessed using the individual contamination factors (ICF) and global contamination factor (GCF). Multivariate sta...

Introduction: This study aimed to assess a good protocol for the contamination indexes, concentration, spatial analysis, and source identification of toxic metals in top soils. Materials and Methods: In the first step, samples were taken from top soil (30 cm) and the metals were extracted and detected with ICP-AES. In the second step, Enrichment Factor, Geoaccumulation Index, and Contamination...

Including a method factor on which all items loaded significantly improved fit of CFAs of both IPIP and NEO-FFI data. Fit was further improved by separating the method factor into two factors representing construct-positive and construct-negative items. The criterion-related validity of conscientiousness increased when uncontaminated by method bias. PRESS PARAGRAPH This research extends previou...

Background: Contamination of the environment due to heavy metals is a major concern to human life and the environment. This study was conducted to investigate and quantify the copper and zinc concentrations in industrial estates soil in Arak, Iran. Methods: Four industrial estates were considered for the experimental design, including Arak 1, Arak 2, Arak 3, and Ghotbe Sanaati. For prelimin...
