Rainfall infiltration exerts great effect on the stability of soil slopes. Based on the actual rainfall data, saturated-unsaturated seepage theory and the mechanical theory of unsaturated porous media, numerical simulations were conducted to examine the seepage field of saturatedunsaturated slope during rainfall infiltration in this paper. The influence of the coefficient with rainfall duration...

In general, permeability measurement results show a strong scattering according to the measurement method, the type of test fluid and the fluid injection condition, even though permeability is regarded as a unique property of porous medium. In particular, the discrepancy between the unsaturated and saturated permeabilities for the same fabric has been widely reported. In the literature, relativ...

Alternanthera bettzickiana (Regel) Nicolson is an erect herb and an ornamental pot plant, which is recorded to be useful in purifying and nourishing blood. It is also claimed to be a soft laxative, a galactagogue and an antipyretic in addition to its wound healing property. The leaves are reported to be used like spinach and in soups. The lipophilic acetone extract of the fresh flowers exhibite...

Background: Sumac (Rhus coriaria L.) belongs to Anacardiaceae family. The dried and powdered fruits are used as a food flavoring and medicinal plant. Objective: In this study, variability of fatty acid composition in some wild sumac fruits were investigated. Method: The samples were collected from their natural origins in central parts of Iran; Isfahan and Markazi province in the September to...

We report herein on the conversion of saturated and unsaturated fatty acids to alkanes over Pt/C in high-temperature water. The reactions were done with no added H(2) . The saturated fatty acids (stearic, palmitic, and lauric acid) gave the corresponding decarboxylation products (n-alkanes) with greater than 90 % selectivity, and the formation rates were independent of the fatty acid carbon num...

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...

Replacing major saturated fatty acids with unsaturated fats, whole grain carbohydrates or plant proteins is an effective way to prevent coronary heart disease, say researchers.

In bioreactor landfill, the leachate flow and moisture distribution depend upon saturated and unsaturated hydraulic properties of municipal solid waste (MSW). The effects of unsaturated parameters have not been studied because of scarcity of the data and variation in unsaturated parameters due to MSW heterogeneity, degree of decomposition, and pore structure. In this study, a numerical two-phas...

Background: The Gundilia tournefortii leaf contains the chemical compound such as saturated and unsaturated fatty acids. Saturated fatty acid includes stearic and palmitic acid and unsaturated include linoleic and oleic acid, that, these compounds inhibit 5 reductase enzyme. The present study was carried out with the aim of determining the effect of Gundilia tournefortii leaf on spermatogenesis...
