Background & Objectives: Air pollution is one of the most important environmental problems in large cities. Aromatic hydrocarbons as volatile organic compounds (VOCs) have been listed in Hazardous Air Pollutants (HAPs) by Environmental Protection Agencies (EPA). The aim of this study is Passive sampling and determination of aromatic hydrocarbons (AHs) toluene, xylene and ethylbenzene using ...
Fifty Holstein cattle, either second to fourth generation daughters of cows randomly bred to non-commercial sires originating in the Virginia Tech dairy herd (estimated mean PDM84 = -455 kg, control animals), or daughters of cows bred to commercially available sires (mean PDM84 = +368 kg, selection animals), were randomly assigned to be milked twice or thrice daily starting at parturition. Seri...
Purification and properties of DNA-dependent RNA polymerase from Bacillus subtilis vegetative cells.
A purification procedure to prepare highly purified DNA-dependent RNA polymerase from Bacillus subtilis vegetative cells is described. The enzyme consists of four different subunits, /?’, /?, (T and 01 (molecular weights 154000 for B’ and /?, 56000 for (T and 43000 for 01) in a molar ratio 1 : 1 : I : 2. By phosphocellulose chromatography RNA polymerase has been disscociated in (T subunit and c...
Traditionally water-ethylene glycol mixture based nanofluids are used in cold regions as a coolant in the car radiators. In the present study, the rheological properties of water-ethylene glycol based graphene oxide nanofluid are studied using Non-Equilibrium Molecular Dynamics (NEMD) method at different temperatures, volume concentrations, and shear rates. NEMD simulations are perfor...
hydrochlorothiazide (hct) is a diuretic agent which is shown to be effective in the treatment of hypertension. literature reports have demonstrated that urinary excretion data may be used to assess the bioavailability of various formulations containing this thiazide. also hct consumption by the athletes is one of the drugs which should be regulated by world anti-doping agency (wada), because of...
In this experiment, the effect of curcumin and ginger hydroalcoholic extract on growth performance and biochemical indicators of blood in rainbow trout (Oncorhynchus mykiss) were examined separately and in combination. The experiment was designed in a completely randomized design with zero levels (control), 0.5% ginger hydroalcoholic extract, 0.5% curcumin and 0.5% curcumin composition + 0.5% g...
