PURPOSE To study the in vitro effect of silicone oil of different viscosities and liquid perfluorocarbons on platelet aggregation. METHODS Silicone oil with a viscosity of 5700 cs and 1000 cs and liquid perfluorocarbons of perfluoroperhydrophenantren and perfluorodecaline were studied to investigate the effect of these agents on platelet aggregation under in vitro conditions. The experiments ...

in order to study the effect of irrigation interval, n fertilizer and superabsorbent on yield and qualitative traits of sesame (sesamum indicum l.), a split-split-plot experiment was coducted in a farm in khusf of birjand, iran in 2009 on the basis of a randomized complete block design. the main plot was devoted to irrigation interval at three levels of 6, 12 and 18 days, the sub-plot was devot...

Biodiesel is a green (clean), renewable energy source and is an alternative for diesel fuel. Biodiesel can be produced from vegetable oil, animal fat and waste cooking oil or fat. Fats and oils react with alcohol to produce methyl ester, which is generally known as biodiesel. Because vegetable oil and animal fat wastes are cheaper, the tendency to produce biodiesel from these materials is incre...

In In order to investigating changes range of oil yield and percentage attention to plant density on three varieties of black seed, an experiment was conducted in the form of factorial based on completely randomized block designs (RCBD) with 4 replications in Saat-Loui agricultural station of West Azerbaijan province. In this research, the first factor (A) contained two levels 20 and 40 cm inte...

in this research, the effects of organic fertilizers (bovine, sheep, leaf mould and vermicompost fertilizers) combined with foliar application of salicylic acid (sa) at the rate of 0, 10-2, 10-4 and 10-6 m on essential oil percentage and some secondary metabolites of lemon balm were investigated. the experiment was conducted as complete randomized block design with factorial arrangement in pots...

This study was conducted to find the effects of fruit ripening and extraction method on the quantity and quality of the Koroneiki olive oil. The oil samples extracted in six ripening stages were used for further quality analysis. Quality assessment of the oil was conducted according to the standard methods and the composition of fatty acids was measured by gas chromatography. The results showed...

Fertile White Leghorn chicken eggs were exposed to 0,1,2,4,6,8, and 16 ÎL of Prudhoe Bay Crude oil (PBCO) on day 9 of incubation. The effects of oil on percentage pipping,percentage hatchability, body weight gains post hatching,serum creatine kinase and pathological changes in the pipping (hatching) muscle (musculus complexus), liver, bursa of Fabricius and other organ systems were assessed dur...

application of organic fertilizers increases quality and yields in the sustainable crop production and considerably replaces or reduces chemical fertilizers. in order to study the effects of different manure and vermicompost rates on yield and essential oil contents of dragonhead, an experiment was conducted as a randomized complete blocks design with eight treatments and three replications in ...

Canola oil was transesterified using a 1 : 1 molar mixture of methanol and ethanol (M/E) with potassium hydroxide (KOH) catalyst. The effects of catalyst concentration (0.5–1.5 wt-%), molar ratio of M/E to canola oil (3 : 1 to 20 : 1) and reaction temperature (25–75 7C) on the percentage yield measured after 2.5 and 5.0 min were optimized using a central composite design. A maximum percentage y...
