In Iran,the hydrogenated vegetable oil have content of frans fatty acids and high per capita consumption.this study was aimed to evaliate the effects of substitution of hydrogenated oil by sunflower liquid oil on plasma levels of LDL,HDL, total cholestero and triglycerids in normal subjects.thirty six healthy inmates participated in this research. they were consuming hydrogenated oil before the...

Introduction Sunflower (Helianthus annus) seeds and byproduct meals are of importance in some parts of the world because they provide a source of high-oil protein material for livestock diets. The major sunflower producing areas of the world today are Argentina, China, Eastern Europe, and the United States. Although Australia produces only relatively small amounts of sunflower meal (Table 1), i...

Rats conditioned to eating fixed-size meals (meals at 7 AM and 7 PM), consuming diets rich in palm oil or sunflower seed oil, were used to study the metabolism of chylomicrons and hepatic very low density lipoproteins (VLDL) as a function of time after meal consumption. Rats fed a palm oil diet had higher serum triacylglycerol levels at 7 AM, before the meal (1.96 +/- 0.25 mM vs. 1.09 +/- 0.09 ...

In this study, preheated crude sunflower oil at 75C was used in a fourcylinder, naturally aspirated, indirect injection diesel engine. The experiments were conducted at the constant engine speeds under the full load condition of the engine to determine the performance, combustion, and injection characteristics of test fuels. The engine test results have been compared with the reference values t...

Application of Granular Activated Carbon (GAC) in adsorption process has been studied for the advanced treatment of municipal and industrial wastewater. Because of entering poisonous compounds such as furfural, phenol and sulfides into the oily wastewater of Tehran refinery, biological aeration basins of wastewater treatment unit may not have the desired performance of COD reduction. In this st...

The purpose of this research was to characterize an olive core collection using some agronomic characters and simple sequence repeat (SSR) markers and to determine SSR markers associated with the content of fatty acids in olive oil. SSR marker analysis demonstrated the presence of a high amount of genetic variation between the olive cultivars analyzed. A UPGMA dendrogram demonstrated that olive...

Reasons for Blending Crude Oils at a Refinery Oil refineries, and especially their on-process units that process the primary crude feed stocks, are not uniform in either design or operation. The refinery process units and the combination of units built and in service at a given refinery location are part of a plan to accommodate a certain slate of crudes based on their properties. These decisio...

A hybrid adsorbent-catalytic nanostructured material consisting of aminopropyl groups and nickel nanoparticles immobilized in mesoporous silica nanoparticles (APNi-MSN) was employed to selectively capture free fatty acids (FFAs) and convert them into saturated hydrocarbons. The working principle of these sorbent-catalytic particles was initially tested in the hydrogenation of oleic acid. Beside...
