Diverse African and non-African samples of the X-linked PDHA1 (pyruvate dehydrogenase E1 alpha subunit) locus revealed a fixed DNA sequence difference between the two sample groups. The age of onset of population subdivision appears to be about 200 thousand years ago. This predates the earliest modern human fossils, suggesting the transformation to modern humans occurred in a subdivided populat...

During episodes ofhypotension the blood pressure feil as low as 32/16 mm Hg, the heart rate fell from a mild tachycardia to normal values or a mild bradycardia, and the central venous p...
متن کاملFabrication and physicochemical investigation of ancient Iranian and Pakistani treated silver particles and their comparison with silver nanoparticles
Iranian and Pakistani traditional physicians have derived the advantages of silver compounds by processing silver to a specific preparation called Kushta to treat skin cancers. This study investigated silver Kushtas in comparison with silver nanoparticles in the terms of morphology, silver content, and chemical composition. Materials and Methods: Iranian silver Kushta (IKAg) powder was produced...
متن کاملMicrowave embrittlement
Mikrovlnné žiarenie frekvencie 2,45 GHz bolo použité na vzorkách uhlia z rôznych anglických lokalit, na ich tepelnú predúpravu pred rozpojovaním. Získané údaje poukazujú na vplyv mikrovlnnej tepelnej úpravy na relatívnu meliteľnosť uhlia. Výrazná redukcia ( 20 –40 % ) relatívnej energie mletia bola zaznamenaná už po pomerne krátkom čase pôsobenia mikrovlnného žiarenia (3 –8 min). Vplyv mikrovln...
