Late Antiquity and Early Islam
In this paper, an investigation on the relation between state-building and Near Eastern religion is attempted. Analyzing the city-state of Ḥaṭrā (Iraq, close to Kirkuk), it is demonstrated that pre-Islamic state craft in the region was dependent on the initiative of the Parthian monarchy in Iran. The kings of the Arsacid dynasty attempted to bestow the local Arabic tribes in the Jazira with a c...
متن کاملinvestigation of the electronic properties of carbon and iii-v nanotubes
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
15 صفحه اولMercury enrichment indicates volcanic triggering of Valanginian environmental change
The Valanginian stage (Early Cretaceous) includes an episode of significant environmental changes, which are well defined by a positive δ13C excursion. This globally recorded excursion indicates important perturbations in the carbon cycle, which has tentatively been associated with a pulse in volcanic activity and the formation of the Paraná-Etendeka large igneous province (LIP). Uncertainties ...
