Acidic soils need to be improved of pH in order maintian sustainable agricultural production. In ameliorate the pH, lime, available Ca and some other properties acidic soils, materials that increase soil value are needed. One these organic substances is gyttja. Gyttja contains 30-40% CaCO3 40-50% matter, which generated as waste Af?in Elbistan thermal power plant its reserve estimated 4.8 billi...

Distribution of lipid classes and groups and fatty acid composition of neutral and polar lipid fractions corresponding to two edible sites (head and tail) were investigated. Proximate composition and essential and toxic mineral contents wer...
Karst features such as polje are highly vulnerable to natural and anthropogenic pollution. The main objectives of this study were investigate the soil quality in Ioannina (north-west Greece) concerning arsenic (As) zinc (Zn), delineate their origin well compare As Zn content with criteria recorded literature. For purpose, geomorphological settings, land use, physicochemical properties mapped ev...
a novel acrylic acid-functionalized fe3o4 magnetic nanoparticle with a core-shell structure was developed for utilization as a heterogeneous organosuperacid in chemical transformations. the structural, surface, and magnetic characteristics of the nanosized catalyst were investigated by various techniques such as transmission electron microscopy (tem), thermogravimetric analysis (tga), and ft-ir...
سنتز پلیمرهای کوئوردیناسیونی جدید از لیگاندهای 2-آمینو نیکوتینیک اسید، 2-کینولین کربوکسیلیک اسید، 2-پیرازین کربوکسیلیک اسید در ابعاد توده، با روش گرایان دمایی و با استفاده از شاخه ی جانبی انجام شده است، این پلیمرها توسط روش طیف سنجی ir شناسایی و پایداری گرمایی آن ها توسط تجزیه های وزن سنجی حرارتی (tga) و تجزیه ی گرمایی تفاضلی (dta) بررسی شده است. در ادامه، ساختار این ترکیبات توسط بلورنگاری پرتو...
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...
Pieces of bread were collected from some regions of the world, and various microorganisms belonging to bacteria as well as yeast were found in the bread samples collected by an optical microscopic observation. SDS-PAGE showed that some of the bread contained mainly partially hydrolyzed proteins, suggesting bacterial proteases hydrolyzing protein and lowering of bread allergenicity. Bread baked ...
a greenhouse experiment was conducted using completely randomised design (factorial) with three replications to study the residual effect of organic manures (municipal solid waste compost and cow manure), zinc (0 and 50 kgha-1) and boron (0 and 10 kg.ha-1) by using znso4 and h3bo3 salts respectively, (applied earlier for millet (panicum italicum l.) crop) on soil properties and chemical composi...
The highest extractable concentration in the artificial sweat fluid was observed for Ba (120mg/kg; d.w.). The highest extractable concentration in the artificial gastric fluid was observed for Al (9030mg/kg; d.w.). Furthermore, the extractable concentrations of Ba (550mg/kg; d.w.) and Zn (400mg/kg: d.w.) in the bottom ash using artificial gastric fluid were elevated. The extractable concentrati...
The rate of metal transfer from the solid phase to solution is an important factor governing their concentration in the soil solution and its availability. In this research, the release rate of Zn in contaminated soils from Isfahan was studied using solutions citric acid, oxalic acid and malic acid 0/01 M during the period of 2 - 504 hours and its relationship with soil characteristics was inve...
