to determine the effect of zn and mn enriched seed on quality of two winter safflower varieties under drought stress, an experiment was conducted at the agricultural faculty research field, tarbiat modarres university, during 2004-2005 cropping season. the design was a split factorial randomized complete block one of 3 replications. main plots were composed of 3 different levels of drought stre...

Quantitative information regarding the endmember composition of the gas and oil that flowed from the Macondo well during the Deepwater Horizon oil spill is essential for determining the oil flow rate, total oil volume released, and trajectories and fates of hydrocarbon components in the marine environment. Using isobaric gas-tight samplers, we collected discrete samples directly above the Macon...

A collaboration between WPI and ENSIC was undertaken to investigate the properties of emulsions as a drug delivery system. The use of biocompatible amphiphilic polymers as emulsifiers for controlled drug delivery is a relatively new technology. The emulsifier acts as a barrier between phases in oil-in-water emulsions to increase stability. Oil soluble drug substances can then be encapsulated wi...

The chemical characteristics of oil feedstocks greatly affect the physical properties of biodiesel. Bacteria, because of their very high growth-rate and their easy culture, can be used for making oilfeedstocks to produce biodiesel. In this way genetic transformation was recently applied to microorganisms to improve oil quality and hence biodiesel quality. In this work, Escherichia coli was gene...

abstract background: gastric cancer is a life threatening disease. recent studies have shown that rosa damascene possesses noticeable biological effects on the human body. this study, investigates the anticancer effect of rosa damascena on gastric cancer cell line mkn45. methods: microscopic studies and mtt assay were used to examine morphological alteration, and cell survival of the cancer cel...

Two important properties-the low surface free energy of polybenzoxazine (PBZ) and the photocatalysis-induced self-cleaning property of titanium dioxide (TiO2) nanoparticles-are combined to develop a promising approach for oil/water separation. They are integrated into a multifunctional superhydrophobic and superoleophilic material, PBZ/TiO2 modified polyester non-woven fabrics (PBZT), through a...

This study investigated the hydrocarbonoclastic microbial community present on weathered crude oil and their ability to degrade weathered oil in seawater obtained from the Gulf St. Vincent (SA, Australia). Examination of the native seawater communities capable of utilizing hydrocarbon as the sole carbon source identified a maximum recovery of just 6.6 × 10 1 CFU/ml, with these values dramatical...

Microbial selection on mixtures of chlorinated and nonchlorinated compounds that are poorly soluble in water and/or toxic to growing microbial cells was examined in both biphasic aqueous-organic and monophasic aqueous systems. A biphasic system in which silicone oil was used as the organic phase permitted the acceleration of acclimation, leading to rapid selection and to an increase in xenobiot...

Long-chain n-3 PUFA from fish oil protect against death from CHD but mechanisms are not well understood. Preliminary results indicate that fish oil may affect the enzyme soluble epoxide hydrolase (sEH) and influence inflammatory pathways in a time-dependent manner. In the present study male apoE knockout (Apoe-/-) mice were randomised to three dietary groups receiving a high-fat high-cholestero...

Johnson, M. L., and Wilson, H. T. H. (1971). Brit. J. industr. Med., 28, 122-125. Oil dermatitis: an enquiry into its prognosis. One hundred industrial workers who developed skin disease while working with soluble or cutting oils were seen. Between 6 and 13 years later 87 of these cases were contacted and their subsequent histories obtained. Of these, 42 had oil dermatitis, 10 had oil dermatiti...
