In the present work, health risk of heavy metals such as As, Cd, Co, Cr, Cu, Hg, Ni, Pb, Zn in Iranian urban and rural samples including wheat, wheat flour, bread, pasta and sweets were assessed. The real amount of heavy metals in target samples were determined by inductively coupled plasma-atomic emission spectrometry (ICP-AES) and atomic absorption spectroscopy (AAS). Wet ashing and hydride g...

This study was performed to assess the prevalence of low birth weight in two cities of Iran and also to evaluate the potential risk factors of it. Materials and Methods: This was a cross-sectional study, performed on 1513 pregnant women attending delivery facilities in educational ho...
در این پایان نامه به بررسی بهره برداری بهینه تامین توان ریزشبکه ها پرداخته می شود. منابع موجود در این ریزشبکه ها شامل منابع انرژی های نو مانند انرژی خورشیدی و توربین های بادی است. همچنین از دو میکروتوربین که دارای قابلیت اطمینان بیشتری نسبت به منابع انرژی های نو در تولید توان هستند بهره برده ایم. به منظور اینکه بتوانیم در ساعات ارزان انرژی، انرژی را از شبکه خریداری کرده و در ساعات پیک از آن بهر...
this paper develops an operational perspective of supply chain sustainability, by considering it as a risk management process. it explores the nature of sustainability-related supply chain risks, distinguishes them from typical supply chain risks and develops an analytical process for their management. an empirical study is conducted to generate insights about how sustainability-related risks s...
Introduction: Soil erosion is the most important factor in damaging and decreasing the productivity of agricultural soils. Moreover, as the transfer of sediments rich in nutrients through the soil leads to soil erosion and in turn to the decrease in the dams’ reservoirs’ storage capacity, bringing about adverse economic and eco-environmental consequences such as damage to land resources and dec...
Forest fire models are generally used in different aspects of fire management and are helpful in understanding and prediction of fire behavior. Forest fires cause a significant damage for public property by destroying a large tract of forest. This helps fire fighters to focus on an area with greater risk and to develop better substructure for fire fighter training and ultimately to plan fire-f...

Thus, this study has identified and evaluated the potential failures by Failure Mode and Effects Analysis (FMEA) approach to eliminate errors occurrence of an Intensive Care Unit (ICU) in a hospital in Tehran city. Materials and Methods: This study...
Background and Purpose—About 60% to 80% of all ischemic strokes can be attributed to increasing blood pressure, blood cholesterol, cigarette smoking, carotid stenosis, and diabetes mellitus (atherosclerotic ischemic stroke), and atrial fibrillation and valvular heart disease (cardiogenic ischemic stroke). The aim of this review was to examine the potential role of other risk factors in the etio...
