Background and purpose: Considering the many benefits of fish in the food basket, it is essential to assess its health risk. The purpose of this study was to examine the risk assessment effects of heavy metals from Dez river fish. Materials and Methods: In order to determine the concentration of heavy metals in the edible parts of fish, 80 samples were caught from the local species of Dez Rive...
Background: Non-biodegradation in nature and the creation of adverse health effects in humans is important features of heavy metals. The main purpose of this study was to determine the carcinogenic and non-carcinogenic risks of heavy metals As, Cd, Cu, Cr, Pb, Ni, V, and Zn in the soils of industrial areas of Mahshahr port for adults and children. Methods: To study the environmental effects of ...
From the perspective of sustainable waste management and its environmental impact, biomass bottom ash (BA) remains problematic challenging to use as a recycling material for civil engineering infrastructures. This study evaluated performance lateritic soil (LS), stabilized with cement BA, subbase material. BA has been considered replacement in LS prior introduction hydraulic stabilization means...
BACKGROUND To identify factors which determine high life satisfaction (LS) and to analyse the prognostic influence of LS on mortality. METHODS Data collection was conducted on 2,675 participants, age 25-74 years, as part of the MONICA Augsburg Project 1994-95. Multivariate logistic regression analyses were used to determine factors associated with high LS (measured with one item, 6-level Like...
this study investigated (a) the learners’ existing reading strategy repertoire, (b) the effect of instruction in reading strategies on learners’ strategic performance, and (c) the effect of explicit instruction in top-down reading strategies on reading comprehension ability of intermediate learners. the study was conducted with 40 intermediate efl learners in two groups of experimental and cont...
Carcinogenic and Non-Carcinogenic Risk Assessment of Some Heavy Metals Due to Consumption of Raisin Produced in Malayer City Eisa solgi1*, Tarokh khodadadi2 1Associate Professor, Department of Environment, Faculty of Natural Resources and Environment, Malayer University 2Ph.D. Student of Environmental Pollution, Faculty of Natural Resources and Environment, Malayer University Abstract In...
abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
Frog sartorius muscles tetanized isometrically were released at a constant velocity from lengths lL to lS (delta l = lL -lS; Ls greater than lO). The tension PS redeveloped after the release was lower than the isometric tension PS at LS, and higher than the isometric tension PL at lL. The tension deficit D is defined as the difference PS-PS. The timing of the release during the tetanus did not ...
Background and Objective: The aim of the present study was to investigate risk of heavy metals on human health including (Pb, Zn, Cu, Cr, Cd, Ni, V, As and Co) in street dusts in Abadan. Materials and Methods: 30 dust samples were collected from sidewalks of main streets of Abadan and analyzed by inductively coupled spectroscopy (ICP-OES) method. Results: The mean concentration of the heavy m...
Background & objectives: In general, contamination of drinking water sources by heavy metals can poses a serious threat to the living organism, especially human. Therefore, this research examines the concentration of some heavy metals in groundwater resources and their impact on consumer health. Methods: In this study, samples were collected from 17 wells in Birjand flood plain, in autumn of 2...
