Co-mutagenic activity of phenoxyherbicides MCPA- and MCPB-ethylester in the Ames assay.

Estimation of Mutagenic and Co-mutagenic Activity of EMFs Using Bacterial Mutation Assay

INTRODUCTION Many studies on the biological effects of electric and magnetic fields have been conducted since Wertheimer and Leeper reported an association between wiring configuration and childhood cancer among residents in Denver, Colorado. The genetic effects, especially mutagenicity and carcinogenicity, of electromagnetic fields have also been studied experimentally with positive and negati...

The Mutagenic and Antimutagenic Activity of Lavandula angustifolia and Elettaria cardamomum Essential Oils in the Bacterial Reverse Mutation Assay

Background: Essential oils from Elettaria cordamomum (cardamom oil) and Lavandula angustifolia (Lavender oil) are used a lot in food and Drug Industry. Cardamom oil traditionally used as spice in food now is increasingly used as diuretic, sedative and for gastrointestinal disease. Lavender oil, traditionally used as an antiseptic agent, is now widely used as a relaxant, carminative, and sedativ...

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

the analysis of the role of the speech acts theory in translating and dubbing hollywood films

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
