Since fish oil has been reported to reduce platelet aggregability, to reduce blood viscosity by increasing red blood cell deformability and to lower blood pressure, we studied the effect of dietary supplementation with fish oil on the occurrence of adverse effects in patients receiving recombinant human erythropoietin (rHuEPO). In a prospective, randomized, double blind cross-over design we stu...

Transesterification of vegetable oils in supercritical methanol are carried out without using any catalyst. Methyl esters of vegetable oils or biodiesels have several outstanding advantages among other new-renewable and clean engine fuel alternatives and can be used in any diesel engine without modification. The most important variables affecting the methyl ester yield during the transesterific...

The physical and chemical properties of raw bio-oil, two oxidized bio-oils, and hydrotreated bio-oil were compared before and after catalytic hydrodeoxygenation using sulfided CoMo/γ-Al2O3 catalyst. Following continuous hydrodeoxygenation, the organic liquid products from treated bio-oils and raw bio-oil were compared for higher heating value, oxygen content, water content, and viscosity. In ad...

Here, we investigate the surface shear rheology of class II HFBII hydrophobin layers at the oil/water interface. Experiments in two different dynamic regimes, at a fixed rate of strain and oscillations, have been carried out with a rotational rheometer. The rheological data obtained in both regimes comply with the same viscoelastic thixotropic model, which is used to determine the surface shear...

In this study, effects of multi walled carbon nanotubes and temperature on rheological behavior of engine oil (10W40) have been examined. For this purpose, the experiments were carried out in the temperature range of 5-55°C for several suspensions with solid volume fractions of 0.025%, 0.05%, 0.1%, 0.25%, 0.5% and 0.75%. The viscosity of all samples was measured in the shear rate range of 666s-...

A systematic process analysis was conducted to study the effect of main variables in an industrial electrostatic desalter, such as electric field intensity, wash water content, droplet size, and oil viscosity, on efficiency separation from oil. The assessed through already published validated CFD multiphase numerical model that considers expression frequency collisions a function mentioned vari...

Interest has risen among utilities in using natural ester (NE) insulating oils in transformers as a substitute for conventional mineral oil. However, present understanding on aging behaviour of NE-paper composite insulation system and knowledge on application of existing condition monitoring tools for NE-based insulation are inadequate. This limits the cost effective and reliable field applicat...

Water-soluble polymers are known to be used in chemically enhanced oil recovery (EOR) processes, but their applications are limited in high-temperature and high-salinity oil reservoirs because of their inherent poor salt tolerance and weak thermal stability. Hydrophobic association of partially hydrolyzed polyacryamide (HAHPAM) complexed with silica nanoparticles to prepare nano-hybrids is repo...

Olive oil is a mixture of several glycerides of (mainly) oleic acid, but also palmitic, linoleic, stearic and arachidic acids, and also contains squalene, phytosterol, tocopherol and phenolic compounds. It is considered to be a weak irritant and a low-risk sensitizer (1), with the actual allergen(s) being unknown. Apart from its culinary use and its presence in cosmetics, itmayalso beused in to...

The present study investigated the physicochemical properties and phytochemical constituents of seed oil of Semecarpus anacardium L. to understand its biopesticidal and therapeutic potential. Preliminary phytochemical studies showed the presence of polyphenolic compounds, flavonoids, tannins, saponins, steroids in seed oil which is extracted using various organic solvents such as n-hexane, petr...
