There is good scientific evidence that dietary fatty acid composition is involved in the aetiology of many diseases. Increasing the supply of n-3 polyunsaturated fatty acids (PUFA) may reduce the risk of CHD. Several scientific organizations (for example, see Department of Health, 1991, 1994; British Nutrition Foundation, 1992; Scientific Committee for Food, 1993; Food and Agriculture Organizat...

Pistachio nut has high nutritional value. The fat and protein are the common part of pistachio. Major part (about 88%) of the fat content of pistachio includes unsaturated fatty acids. Unsaturated fatty acids are known to have positive effects on human health like preventing to heart diseases. This research has evaluated protein, fat and fatty acids content of some commercial pistachio cultivar...

The present study was conducted to evaluate the effect of low-dose gamma irradiation (0, 1, 3 and 5 kGy) on fatty acid composition of Rainbow trout (Oncorhynchus mykiss) fillet. Among all of the fatty acids, oleic acid (C18:1) (with mean 33.50±3.02 g/100 g fatty acids) and myristoleic acid (C14:1) (with mean 0.41±0.26 g/100 g fatty acids) were the most predominant and the lowest fatty acids in ...

Steady-state and transient one-dimensional unsaturated flow in vertically stratified porous media are examined. Saturated hydraulic conductivity and the alpha parameter of the exponential hydraulic conductivity function were assumed to vary from soil layer to soil layer. The use of effective unsaturated hydraulic conductivity to compute matric potential in the soil profile is demonstrated. Resu...

A significant range of organic and mineral binders produced by the industry allows for a wide variety combinations, providing resulting compositions. This, in turn, makes it necessary to establish general regularities formation their properties. An attempt is made this article. The results studies properties concrete, which are composition Portland cement, fine aggregate mineral–organic complex...

Selective hydrogenation of the carbon-oxygen bond in α,β-unsaturated carbonyl compounds is a synthetic challenge, since C=C bond reduction is thermodynamically more favorable (35 kJ mol–1) than C=O bond reduction.[1] This problem becomes even more complicated by the presence of an aromatic substituent in such systems because of possible ring hydrogenation.[2] Moreover, the transformation of uns...

The present study introduces two quantitative parameters to compare the accuracy of ultrasonic C-scan testing and X-ray radiography methods in the damaged area detection under low-velocity impact in polymer-based composites. For this purpose, the hand lay-up technique of composite processing was employed to prepare the composite specimen. A composite specimen consisting of the glass fiber reinf...

Nanocomposite metal and metal oxide plasma polymers can be utilized for many applications such as optical coatings, protective films, biomedical materials etc. Mechanical, optical, electrical properties of such nanocomposites are shortly reviewed below. Particularly optical and electrical properties as a function of the filling factor are presented too. The experimental part of the paper descri...
