Pathological skeletal remains from ancient Egypt: the earliest case of diabetes mellitus?

Authenticating DNA Extracted From Ancient Skeletal Remains

The survival of DNA, the most informative biological molecule, for periods of at least several thousand years in bone was demonstrated more than four years ago. However, difficulties with authenticating ancient DNA have made diagenetic studies problematic. It is therefore essential that these problems be overcome before the question of DNA survival can be addressed. Here we describe our work wi...

the effect of traffic density on the accident externality from driving the case study of tehran

در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...

DNA preservation: a microsatellite-DNA study on ancient skeletal remains.

To determine the effect of environmental factors on the preservation of DNA, archeological teeth of approximately similar age but greatly differing site milieu were examined for DNA content. The complex relational system of locational milieu of the samples was reduced to its essential and, at the same time, easily measurable factors. These are temperature, humidity, pH value, the geochemical pr...

Examination of Human Skeletal Remains and Artifacts from el-Qantir, Egypt

uring a recent excavation of a common grave on the outskirts of el-Qantir, Egypt, a human skeleton, mummified cat and vase from the First Intermediate Period of the Eleventh Dynasty were discovered. Based on similar findings in the surrounding area, the human skeleton was surmised to be a mummy, decomposing because of water from a nearby irrigation system. Carbon dating concluded the archaeolog...
