Vegetable oils are promising candidates as base fluid for eco-friendly lubricants because of their excellent lubricity, biodegradability, viscosity–temperature characteristics and low volatility. Their use, however, is restricted due to low thermo-oxidative stability and poor cold flow behavior. This paper presents a systematic approach to improve the oxidation behavior and low temperature flui...

The aim of this study is to define the possible effects of vegetable oils used as vitamin E vehicle on the electrical activity of the rat heart. To test the possible effects of vitamin E vehicles we studied the effect of i.p. injected corn oil, hazelnut oil or peanut oil on the action potential parameters recorded in both papillary and left atrial muscle strips. Four experimental groups were us...

Cost and limited reserves of conventional fossil fuels have intensified the search for alternative fuels for use in internal combustion engines. A possible alternative engine fuel is vegetable oil because it is a clean burning, renewable, non-toxic, biodegradable and environmentally friendly transportation fuel. It can be used in a neat form without any modification of the engine. Vegetable oil...

272 India accounts for 12-15% of world’s oilseed area, 7-8% of oilseeds output, 6-7% of vegetable oil production, 9-12% of vegetable oil import and 9-10% of vegetable oil consumption (Hegde, 2009). The country produces seven edible oilseed crops viz. groundnut, rapeseed-mustard, soybean, sunflower, sesame, safflower and niger and two non edible oilseeds viz. castor and linseed. Though the diver...

Self-sustaining treatment for active remediation (STAR) is an innovative soil remediation approach based on smoldering combustion that has been demonstrated to effectively destroy complex hydrocarbon nonaqueous phase liquids (NAPLs) with minimal energy input. This is the first study to explore the smoldering remediation of sand contaminated by a volatile NAPL (trichloroethylene, TCE) and the fi...

This work studied the development of vegetable based lubricants and the addition of oxides nanoparticles (ZnO and CuO) as additive for extreme pressure (EP), exploring the EP and oil base influence in tribological behavior. The results showed that with the addition of nanoparticles to conventional lubricant, the tribological properties can be significantly improved. A smoother and more compact ...

Biodiesel is a promising alternative diesel fuel obtained from vegetable oils, animal fats, or waste oils by transesterifying the oil or fat with an alcohol such as methanol. In an extension of previous work, fiber-optic near infrared spectroscopy was used to quantitatively monitor the transesterification reaction (6-L scale) of a vegetable oil (soybean oil) to methyl soyate. The results were c...

Three "saturated" fats of vegetable origin were fed to different groups of rabbits for periods up to 1 year. Cocoa butter and a hydrogenated vegetable oil shortening produced no hypercholesterolemia. Coconut oil feeding increased the serum cholesterol concentrations for 4 months, but a decline to baseline values occurred after 6 months. No gross atherosclerosis occurred in any animal fed coconu...

Background: Depression is a complicated disturbance affected by a collection of biological and environmental factors. The first aim of psychiatric studies is to recognize biological markers that could be utilized to predict improvement and increase reactions to antidepressant treatments. Diet affects different aspects of health, including depression. The aim of study was to determine antidepres...
