For a better understanding of the hyperlipidemic function of saturated fat, we have studied the comparative effects of diet supplementation with 10 and 20% coconut oil on the main lipid classes of chick plasma. Changes in fatty acid composition of free fatty acid and triglyceride fractions were parallel to that of the experimental diet. Thus, the increase in the percentages of 12:0 and 14:0 aci...

Soil and surface water contamination by used lubricating oil is a common occurrence in most developing countries. This has been shown to have harmful effects on the environment and human beings at large. Bioremediation can be an alternative green technology for remediation of such hydrocarbon-contaminated soil. Bioremediation of soil contaminated with 5% and 15% (w/w) used lubricating oil and a...

rosmarinus officinalis is one of the most important medicinal and aromatic plants around the world. essential oil as a weapon against biotic and abiotic stresses plays an important role in essential oil bearing plants. in this study the essential oil content and constituent of plants containing bacterium-gall on the shoots and crown was compared with non-contaminated plants. essential oil perce...

Layton, Herbert W. (Northwestern University Medical School, Chicago, Ill.), and Guy P. Youmans. Effect of dietary factors upon the resistance of albino mice to experimental infection with Mycobacterium tuberculosis. J. Bacteriol. 90:958-964. 1965.-Each of the major nutritional components of a synthetic diet was quantitatively altered to determine its effect upon the resistance of albino mice to...

The environment is considered as man’s important asset that must be protected for his life support. Regrettably the situation is different where oil refinery and petrochemical plants operate. Environmental pollution in the form of emissions and effluent discharge in these area poses serious threat to the ecosystem particularly soil, often with undesirable effects. The study collected soil sampl...

The extraction of coffee oil from roasted beans with supercritical carbon dioxide under different conditions of pressure and temperature was studied to measure the influence of these parameters on the yield and fatty acid content in the oil. For this purpose a 2 factorial experimental design using the response surface methodology was realized. The extraction was performed in a pressure range fr...

Microbial degradation of petroleum hydrocarbons is one of the major practices in the natural decontamination process. We tested the effectiveness of some carriers and immobilization methodology for four cultures of hydrocarbon-degrading strains isolated from oil-polluted wastewater of the American Petroleum Institute (API) separators (1, 2, and 4) of the Alexandria Petroleum Company (APC), Alex...

In the present study, ultrasound-assisted extraction of oil from rice bran was investigated through response surface methodology (RSM), where process variables were amplitude level (50–100%) and sonication time (5-30 min). It was found that all process variables had significant (p<0.05) effects on the response variable. A central composite design (CCD) was used to determine the optimum process ...

in order to study the effect of drought stress and harvesting stages on quantitative and qualitative yields of coriander (coriandrum sativum l.) this experiment was conducted on split plot based on a randomized completely block design with 3 replications in torbat-e heydariyeh university, iran, during growing season of 2010-2011. treatments were drought stress (in three levels no stress: contro...

Sunflower (Helianthus annuus L.) grain and oil quality are defined by grain weight and oil percentage, oil fatty acid composition and the amount of antioxidants. The aim of this work was to establish and validate a simple model, based on published relationships, which can estimate not only yield and its components, but also grain and oil quality aspects which are of relevance for industrial pro...
