in this study, scour of mashkid bridge pier located in mashkid river of saravan county has been studied and to measure the scour rate, the numerical model hec-ras 4.0 has been used. upon selection of mashkid river as the case study and whereas the studied zone is important with respect to the climatic conditions and showery monsoon raining and flowing the great and destructive floodwaters, ther...
HOLLANDER, WALTER, JR., ROBERT W. WINTERS, T, FRANKLIN WILLIAMS, JOHN BRADLEY, JEAN OLIVER AND LOUIS G. WELT. Defect in the renal tubular reabsurption of water associated with potassium depletiun in rats. Am. J. Physiol. I&J(~): 557-563. q57.---The effect of graded degrees of K depletion on the ability to produce a concentrated urine was studied in Sprague-Dawley rats. With increasing degrees o...
the importance of groundwater as a source of water supply in arid, semi –arid areas in recent years due to the uncontrolled exploitation of groundwater have been doubled. uncontrolled exploitation has been caused a drop in the water table in many areas of the country, including this region. with replace methods of modern irrigation instead of traditional irrigation methods can prevent drop the ...
to evaluate the effect of bio-fertilizers on physiological traits in soybean under water deficit condition, agreenhouse experiment was conducted in 2011, at faculty of agriculture, tarbiat modares university,using a factorial design based on rcbd with three replications. the experimental treatments weredifferent irrigation regimes including non-stress (40% water depletion), moderate stress (60%...
Groundwater resources are important sources for the supply of water in agriculture, industry and drinking in Ardabil plain, therefore underground water resources planning and sustainable management of these resources are important. The purpose of this study is grading the villages in the plain of Ardabil in underground water crisis and changes during the years 1360-1391. The information obtaine...
Shahrekord aquifer is depleted by almost 800 deep and semi-deep wells, the majority of which are agricultural wells and some have urban usage. In southern parts of the plain, the water table has fallen strongly because of immoderate discharge and decreased the quality of water by urban wastewater. The main objective of this study is investigation of subsurface dam construction and its effects o...
background ochratoxin a (ota) is a toxic secondary metabolite produced by fungi belonging to aspergillus and penicillium genera. the production of ota is influenced by environmental conditions and nutritional requirements. the postharvest application of bunches of table grape fruit (tgf), with water activity of 0.8 aw, was highly effective for controlling ota contamination in vitro and in vivo ...
concerns about nitrate pollution in groundwater and downstream systems cause development of surface water management system to reduce losses of agricultural drainage water nitrate in subsurface drainage using subsurface irrigation from existing drainage lines, drainage water during the growing season and out of season is controlled. the overall objective of this study was to evaluate the effect...
this study aimed to explore concentration of a low grade sulfide-oxide lead-zinc sample containing 2.3% pb, 1.91% zn taken from changarzeh mine, south natanz, iran. the effects of different parameters such as type and dosage of collector, milling retention time, dosage of sodium sulfur and its preparation time, application of sodium silicate, ph and solid content were investigated in relation t...
