Due to severe fluctuations in rainfall in different regions of Iran, droughts are amongst natural disasters which occurs in negative fluctuations, when rainfall is lower than long term average and forcing adverse effects on agriculture and economy. Meteorological drought is one of the droughts that occurs in the earliest stages of drought phenomenon. In this study, using standardized precipitat...
The aim of this study was the effect of raw water quality on the efficiency of domestic reverse osmosis apparatus in Khuzestan province. The results showed that the purified water quality was related to the quality of entrance raw water. With increasing in salt concentrations (EC) or TDS, purification efficiency was decreased. The cation and anions content of refinery water was related to TDS a...
Power stations with high heads are nowadays almost without exception designed so as to have one pipeline, or a few pipelines, supplying the water to the turbines. The penstocks are connected to a distributor, which has the task of distributing the flow with the lowest possible losses of energy to the individual turbines. The function and location of this section of the plant make it understanda...
ABSTRACT Background and Objective: Mycotoxins are a group of relatively resistant toxic metabolites. The most important mycotoxins are aflatoxins (B1 and B2, G1 and G2), which originate from contaminated animal feed. Dairy cattle transmit aflatoxins B1 and B2 through milk in form of aflatoxins M1 and M2, and endanger the human health. Traditional buff...
BACKGROUND Pleurotus giganteus (Berk. Karunarathna and K.D. Hyde), has been used as a culinary mushroom and is known to have medicinal properties but its potential as an anti-inflammatory agent to mitigate inflammation triggered diseases is untapped. In this study, the molecular mechanism underlying the protective effect of ethanol extract of P. giganteus (EPG) against lipopolysaccharide (LPS) ...
Rivers are discussed as sources of water supply for various uses including agriculture, industry anddrinking. Thus, monitoring the quality of these resources due to the recent drought and urban and ruraldevelopment is one of the important tasks in the field of environmental management. In this study,nine stations sampled seasonally the Karoon river, Dez, Karkheh in a one-year period from Octobe...
Studying the morphology of the rivers and identifying the causes of these changes are widely useful in determining the evolution of rivers and planning the maintenance of the river system. The Karun River, between Bandar-e-Khoramshahr and the constant flow of water in the country, plays an important role in the country's water cycle. Due to the morphological changes of this river that have disr...
Surface water resources, especially rivers, are at risk more than other sources for the reason of many uses. This study aims to examine some quality parameters of Karun river water in the Gotovand spatial range to Ahwaz during the years of 2010-2013.The data investigated in this study were obtained from the annual mean biochemical parameters measurements at nine sampling stations at the Water A...
In this study, using Modis images and wets pass model, the value of evapotranspiration for the northern Karun basin was estimated monthly from 2000 to 2014. The value of correlation coefficient for the obtained evaporations was R2 = 0.72. This model was calibrated and verified for different regions with different parameters. Data from 2000 to 2009 were used for calibration and data from 2010 to...
In the present study, in order to evaluate the drought tolerance indices and their relationship with ISSR markers, 12 rapeseed genotypes were studied using a factorial experiment based on completely randomized block design under the three irrigation treatments (control and irrigation after drainage of 60 and 85% moisture content) in the greenhouse of Mohaghegh Ardabili University, Iran. Drought...
