INTRODUCTION Oil spill in fresh water can affect ecological processes and accordingly it can influence human health. Iran, due to having 58.8 % of the world oil reserves, is highly vulnerable to water contamination by oil products. AIM The aim of this study was to determine environmental factors affecting the management of the oil spill into one of the river in Iran using the PESTLE analysis....

the chamomile species of anthemis triumfettii (l.) all is one of important medicinal plant belong to compositae family and it grows as wild species in zagros and alborz mountains, iran. the aim of this study was to evaluation of morphological and phenological traits and their relationships with essential oil. seeds of seven accessions were sown in jiffy pots and transferred to field using rando...

We have previously reported the use of a combination of computational simulations and targeted experiments to build a first generation mathematical model of peppermint (Menthaxpiperita) essential oil biosynthesis. Here, we report on the expansion of this approach to identify the key factors controlling monoterpenoid essential oil biosynthesis under adverse environmental conditions. We also inve...

In this study, in order to introduce natural antioxidative vegetable oil in food industry, the kolkhoung hull oil and kernel oil were extracted. To evaluate their antioxidant efficiency, gas chromatography analysis of the composition of kolkhoung hull and kernel oil fatty acids and high-performance liquid chromatography analysis of tocopherols were done. Also, the oxidative stability of the oil...

physical and chemical properties of  crude oil, including viscosity and api gravity, are commonly inherited  from the  early organic matter, environmental conditions in which they were deposited and depth of burial of the source beds. api gravity increases in deeper burial due to higher thermal maturation of organic matter in the source rocks and consequently, generation of lighter saturated hy...

Deepwater Horizon (DWH) oil causes developmental cardiotoxicity in fish species, but the molecular mechanisms are still not well understood. MicroRNAs (miRNAs) play key roles in a number of biological processes, including heart development. Therefore, the expression of miRNAs in mahi-mahi (Coryphaena hippurus) exposed to weathered slick oil and nonweathered source oil was analyzed. miRNAs were ...

Decline curve analysis models are frequently used but still have many limitations. Approaches of decline curve analysis used for naturally-fractured reservoirs developed by water flooding have been few. To this end, a decline analysis model derived based on fluid flow mechanisms was proposed and used to analyze the oil production data from naturallyfractured reservoirs developed by water floodi...

Antioxidant activity of phytosterols, oryzanol, ferulic acid ester of sterols, corn fiber oil, and rice bran oil was investigated. Commercial soybean oil and distilled soybean oil FAME were used as substrates for both oxidative stability determination and viscosity analysis after the oil was oxidized. At low concentration, these materials did not improve the oxidative stability of the oil subst...
