many researchers have reported positive effects of converter sludge and slag, two by-products in isfahan iron melting factory. in this work, the optimum rate of application and the availability of some essential elements (for plant growth) in the converter sludge and slag for corn were investigated. the converter sludge contains about 64% fe іі and ііі oxides and some other essential elements f...

based on the date obtained through food consumption surveys conducted by the institute of nutrition and food technology research (during 1991-95), the dietary quality of seven provinces (eastern azerbaijan, isfahan, tehran, khorasan, khouzestan, sistan-baluchestan and fars) was assessed. using allowances figures for developing countries, single value nutrient density (s.v.n.a.) was designed for...

abstract soil nutrient management with efficient fertilizer use has an important role on maximizing yield and environmental effects. in this study game theory is applied to identify the nutrient proportion for corn production in kooshkak in fars province, iran, in 2008-2009. cost of fertilizer combinations and production of corn are the players of the game. a goal programming was applied to obt...

in this study, the effects of late gestational undernutrition (lgu) on plasma concentration of insulin-like growth factor 1 (igf-i), leptin, insulin and glucose in subsequent sucking lambs was investigated. ten twin-bearing ewes were fed either restrictedly (restricted) or adequately (control) during the last six weeks of gestation and were fed ad libitum after parturition. blood samples were t...

the purpose of this work was to test the efficiency of the treatment of wastewater by infiltrationunder laboratory conditions, to remove bacterial and organic load and to convert it to available nutrient for crop plants. in order to achieve this objective, polyvinyl chloride (pvc) columns of 133 cm of height were used. the columns were filled with sand and/or pozzolana and loaded with municipal...

this study was carried out to determine nitrogen, phosphorus, and potassium contents of rangeland plants using spectral reflectance value. the measurements were made in 1 m2 area of different parts of a rangeland. a portable spectroradiometer capable of measuring the wavelength range of 325-1,075 nm of the electromagnetic spectrum was used to collect spectral data. spectral measurements were ma...

seed protein quality is an important topic in the production of soybean. the quality of soybean proteins is limited by anti-nutrient proteins and low levels of essential sulfur amino acids. in this study, protein content and solubility of six cultivars were evaluated and seed storage proteins were analyzed using sds-page and scanning densitometry. the results showed that seed storage protein ba...
