Diabetes was induced by intraperitoneal injection of streptozotocin (35 mg/kg bw) in all rats of five groups after being fed for 2 weeks high-fat diet. Type 2 diabetic Nerium-oleander- (NO-) administered groups received the NO distillate at a dose of 3.75, 37.5, and 375 μg/0.5 mL of distilled water (NO-0.1, NO-1, NO-10, resp.); positive control group had 0.6 mg glibenclamide/kg bw/d by gavage d...

Since deodorization distillate, a by-product of rice bran oil production, contains squalene (ca. 8%) and phytosterols (ca. 4%) as unsaponifiable components, the concentration of those materials for their use in the cosmetics and food industries is desirable. In the present work, a novel fractionation method of concentrating squalene and phytosterols from deodorization distillate or the unsaponi...

the occurrence of blindness after drinking some herbaceous distillates is created some anxieties in iran. in this study, the effectiveness of concentration of khalvash distillate was studied on the function of the new modified suggested chromotropic acid method for qualitative detection of methanol. for this purpose, three samples of khalvash distillate were purchased from vendors of rasht. acc...

mL of the distillate with 10 mL of 25 mmol/L H2S04 solution and rinsed the outside of the adapter with a little water.

The use of liquid fuels necessitates methods to assess the quality and suitability of these fuels for their intended use. Traditionally, this is performed through a series of chemical and physical tests. However, in some operational situations, streamlined methods to reliably evaluate fuel quality would offer distinct advantages. The Naval Research Laboratory has been engaged in a research prog...

There is growing interest in biodiesel (fatty acid methyl ester or FAME) because of the similarity in its properties when compared to those of diesel fuels. Diesel engines operated on biodiesel have lower emissions of carbon monoxide, unburned hydrocarbons, particulate matter, and air toxics than when operated on petroleum-based diesel fuel. Production of fatty acid methyl ester (FAME) from rap...

We attempt to determine the impact of production decisions on the price of heating oil. A model for the production of distillate fuel oil is proposed. Its solution, obtained using stochastic dynamic programming, closely matches history. By perturbing the problem in a deliberate manner, we can determine the value of additional units of inventory by examining diierences in costs. Using these diie...

A miniature ion trap mass analyzer was applied to the analysis of traces of hydrocarbons and simple heteroatomics in the vapor phase and in aqueous solution. Vapors of acetone, acetic acid, acetonitrile, benzene, butanethiol, carbon disulfide, hexane, dichloromethane, naphthalene, toluene and xylenes were detected and quantified using solid sorbent trapping and, in some cases, by passage throug...

The presence of multicomponent nonaqueous-phase liquids (NAPLs) on contaminated sites critically alters the biodegradation susceptibility of many target pollutants, including polycyclic aromatic hydrocarbons. This study investigated the effects of petroleum-derived multicomponent NAPLs on biodegradation of benzo[a]pyrene by a bacterial consortium in liquid culture. When high-boiling point diese...
