analysis of power in the network society
اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
15 صفحه اولMineralogical constraints on the paleoenvironments of the Ediacaran Doushantuo Formation.
Assemblages of clay minerals are routinely used as proxies for paleoclimatic change and paleoenvironmental conditions in Phanerozoic rocks. However, this tool is rarely applied in older sedimentary units. In this paper, the clay mineralogy of the Doushantuo Formation in South China is documented, providing constraints on depositional conditions of the Ediacaran Yangtze platform that host the ea...

متن کاملPrediction of nickel mobility in a clayey formation requires accurate knowledge of the mineralogical assemblage
In the perspective of nuclear waste storage, 63 Ni is one of the radio-elements of primary concern. Modeling of its retention in clay formations is usually performed using modeling approaches which consider that only phyllosilicates participate to retention. However, isotopic exchange with stable nickel contained in phases (i.e. minerals and organic matter) from the clay formation may play a ro...
