Introduction: Water quality is essential for industries because they play an important role in countries’ economic development. Groundwater is one of the most widely used resources, and when the ionic constituents were increasing higher than the allowable limit, it increases the cost of maintenance and production in the industries. Materials and Methods: In order to evaluate groundwater corros...
Introduction: Due to water scarcity and increased water consumption during the past years, the importance of water in terms of transmission of diseases, as well as Iran's climate, groundwater aquifers are known as the most important resources of drinking water supply. Using the Water Quality Index (WQI) is considered as strong managerial tool for decision making in water resource management. Th...
there are different materials and compounds in water that determine its chemical and physical quality. as the result of special conditions such as increase and decrease in discharge, water quality can vary. one of these conditions is drought that decreases discharge, and water quality changes. in this study, droughts of sistan and baluchistan province have been analyzed using standardized preci...
Background : Occurrence of corrosion and deposition in drinking water in distribution system can leads to economic and health damages. The aim of this study was to investigate the corrosion and precipitation potential of drinking water in Kerman distribution system. Methods : This cross-sectional study was performed from September to November of 2011. For determining the chemical quality of...
Background and Aims: In this study we measured the quality, corrosiveness, Ryznar stability index, and heavy metal leakage in the drinking water distribution networks of Ahvaz. Materials and Methods : A total of 76 sampling sites were selected for this purpose the sites included inlet and outlet points in water treatment plants as well as consumers taps. We collected 456 samples in six stages a...
abstract different definitions have been proposed for soil quality. various soil properties have been suggetsted as soil quality indices by researchers. this research was conducted to study the relationship between slope of retention curve at its inflection point (s index) and other soil physical quality indices, because the reserches between s index and soil physical properties are little. thi...
The purpose of this paper was to assess the groundwater quality near Qaemshahr landfill site using the Iran Water Quality Index for Groundwater Resources-Conventional Parameters (IRWQIGC). In this study, samples were taken from 11 wells with three replications in February 2015 and water quality was assessed by evaluating nitrate, fecal coliform, electrical conductivity (EC), pH, total hardness,...
This study aims to identify and determine species diversity and richness of the Gastropods of the intertidal zone of Bushehr seaport coastal area and assess the ecological status of this area using Welch index. Sampling was carried out at 6 stations in Bushehr seaport in the winter and summer seasons during 2013-2014. Bed sediment sampling was done three times in each station and Gastropod samp...
the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
this exploratory study aimed to investigate a possible relationship between learners’ beliefs about language learning and one of their personality traits; that is,locus of control (loc). both variables, beliefs and locus of control, are assumed to influence the language learning process. the internal control index (ici) and the beliefs about language learning inventory (balli) were administered...
