heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

Background and Aim: The level of fatty acids in human diets, affecting the atherogenic and thrombogenic indices, which has an important role in the function and healthiness of cardiovascular system. Due to high level of cholesterol, eggs are risky regimen for cardiovascular patients. This study was conducted to modify the composition of layer ration for reducing the risk of cardiovascular disea...

Introduction: Total parental nutrition is essential in premature newborns who are unable to have oral feeding. Intra venous Lipid (Intra lipid) is used to preparing essential fatty acids and a compact source of energy. We aimed in this study to investigate the effect of skin intra lipid. Methods: Premature newborns, who were through admitted in NICU unable to feed orally, were investigated in...

The esterification process causes some desirable changes in physicochemical properties of fat by exchanging the acyl groups in triglyceride molecules. The aim of this study was to produce a suitable edible fat for industrial and home uses. In this study a mixture of 60 percent soybean oil and 40 percent edible tallow were inter-esterified, using 0.5 percent sodium methylate or ethylate as catal...

abstract tasks nowadays are at the center of attention in sla research. task types is one of the critical issues in this regard, their effectiveness and suitability to any particular context, their characteristics and the result they yield are among some of these issues. on the other hand, discourse markers (dms) have been very much investigated and their effectiveness in conveying the meaning...
