Salinity of soil is a major abiotic stress limiting the crop production and growth of safflower. To mitigate stress, the effects of penconazole (PEN) on the growth of safflower were studied to understand the underlying mechanisms of salt tolerance. PEN, a triazole derivative, which has both fungicidal and plant growth regulator properties, protects plants from several types of abiotic stresses....

The fatty acid and positional specificities of Saccharomyces cerevisiae (UI-SACCH) and Schizosaccharomyces octosporus (NRRL Y-854) in the hydrolysis of lard were studied by using gas-liquid chromatography. Synthetic triglycerides were used to determine the positional specificities of the lipases of both organisms. Palmitic acid is specifically cleaved from all three triglyceride ester positions...

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...

Effects of hyperbranched polyesters on kinetics of the reaction between hydroxyl-terminated polybutadiene (HTPB) and isophorone diisocyanate (IPDI) were investigated. HTPB and IPDI were in-situ cured in the presence of two different hyperbranched polyesters, stearic acid ester-terminated hyperbranched polyester (SHPE) and acetate-terminated hyperbranched polyester (AHPE). The curing processes w...

Zirconia ceramics with porous structure have been prepared by solid-state reaction using yttria-stabilized zirconia and stearic acid powders. Analysis of its microstructure and phase composition revealed that a pure zirconia phase can be obtained. Our results indicated that its porosity and pore size as well as the mechanical characteristics can be tuned by changing the content of stearic acid ...

The effects of beef tallow and cocoa butter, two fats with a high stearic acid content (C18:0), on serum lipid and lipoprotein concentrations were compared with the effects of butter fat and olive oil in 10 middle-aged men. Liquid-formula diets containing 40% of the calories from the test fat were fed in random order for 3 wk each, with lipoprotein concentrations measured on the last five days....

BACKGROUND Fatty acid-induced apoptosis and ER stress of pancreatic β-cells contribute to the development of type 2 diabetes, however, the molecular mechanisms involved are unclear. AIMS In this study we have tested the role of caspase-2 and suggested ER stress mediator JNK in saturated fatty acid-induced apoptosis of the human pancreatic β-cells NES2Y. RESULTS We found that stearic acid at...

Abstract The corrosion performance of phase change materials on stainless steel was studied using single fatty acid, acid/paraffin mixed and acid/paraffin/graphite composite as media. results show that the paraffin graphite to is very small; among them, stearic acid series are least corrosive can be used ideal energy storage medium for heat exchange devices.

Abstract The study examined the effect of stearin and paraffin adulteration wax foundation on brood survival. In combs formed a stearin-adulterated (10, 30, 50% stearin, which means: 3.9, 11.7, 19.5% stearic acid, respectively), survival decreased statistically significantly ( p ? 0.001) compared to rates noted pure beeswax foundation. appearance resembled so-called scattered although queens ov...
