Introduction: Due to side effects of antiinflammatory drugs such as dexamethasone and indomethacin, there is a less tendency to use them. On the other hand, the use of medicinal plants has been common in the treatment of inflammation since ancient times and also, using of the plants is increasing. Present research investigated the antiinflammatory effect of the hydroalcoholic extract of capitol...

The purpose of the present work is to show that light straight-run gasoline fraction can be used as feedstock for hydro-catalytic isomerization process, and isomerized product serve a component obtaining pure ecological commercial brand Euro-4 Euro-5. Transformation n-alkanes Zhanazhol oil’s with boiling temperature 180°C was studied. Isomerization carried out in flow unit stationary layer modi...

Aromatic compounds belong to one of most widely distributed classes of organic substances used in industry, services and households and, therefore they are relatively often measured in municipal wastewater. Their efficient biological degradation is essential to reduce the subsequent disposal of such substances into the waters of the receiver, or release into the atmosphere. The mineralization o...

Abstract: Chromatographic measurements were made for the adsorption of benzene, toluene and m-xylene on molecular sieving carbon (MSC) in a supercritical fluid CO2 mixed with organics. A supercritical chromatograph packed with MSC was used to detect pulse responses of the organics. Adsorption equilibria and adsorption dynamic parameters for organics were obtained by moment analysis of the respo...

In this research project, the nitrito nitro isomerization of [Co (NH3)5No2]F2 complex has been studied. Isomerization of this complex in the solid state follows a first order kinetics. The rate of isomerization at different temperatures was determined using a Fourier Transform Lnfrared Spectrophotometer. ? and ? are calculated at 298 K. The infrared, visible and ultraviolet spectra of th...

A batch-type dynamic headspace (HS) system was used to generate vapor-phase volatile organic compounds (VOCs) from a pigpen slurry sample. Sorptive removal capability of MOF-199 and other sorbents (zeolite (ZL) and activated carbon (AC)) was assessed against a total of 13 slurry-borne odorants ((methyl ethyl ketone (MEK), isobutyl alcohol (i-BuAl), benzene (B), toluene (T), p-xylene (p-X), m-xy...

Toluene and xylene are aromatic hydrocarbons commonly used as an industrial solvent for the manufacturing of pharmaceuticals, paints, and chemicals. The Occupational Safety and Health Administration has determined that toluene levels of 2000 parts per million (ppm) are considered dangerous to life and health. Several studies have examined the absorption of toluene and xylene following inhalatio...

There are numerous biomonitoring programs, both recent and ongoing, to evaluate environmental exposure of humans to chemicals. Due to the lack of exposure and kinetic data, the correlation of biomarker levels with exposure concentrations leads to difficulty in utilizing biomonitoring data for biological guidance values. Exposure reconstruction or reverse dosimetry is the retrospective interpret...
