Noble Gas Measurements of the Grant Iiiab Iron Meteorite
Introduction: In contrast to stony meteorites, which have exposure ages usually not higher than a few tens of million years, most iron meteorites exhibit cosmic-ray exposures of hundreds of million years. Consequently, iron meteorites have collected information about the solar system, encoded in cosmogenic nuclides, for much longer than stony meteorites. Iron meteorites are therefore indispensa...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Metallographic cooling rates of the IIIAB iron meteorites
An improved computer simulation program has been developed and used to re-measure the metallographic cooling rates of the IIIAB irons, the largest iron meteorite chemical group. The formation of this chemical group is attributed to fractional crystallization of a single molten metallic core during solidification. Group IIIAB irons cooling rates vary by a factor of 6 from 56 to 338 C/My. The coo...
متن کاملthe 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...
15 صفحه اولThe first report of Asterodiscides fourmanoiri (Echinodermata: Asteroidea) from the North Coast of Oman Sea, Iran
Echinoderms with around 7,000 species can be found at all depths of the marine ecosystems. Body shape is radially symmetrical, covered by calcareous plates and five body parts are around a central axis. The class of Asteroidea (also known as starfish or sea star) is one of the most diverse groups within the phylum Echinodermata, including nearly 1900 extant species grouped into 36 families, and...
