Although prehistoric periods (especially Chalcolithic) on the western side of the Central Zagros Mountain are fairly known, the Songhor and Koliyaei Plains have not been sufficiently investigated by western  or  Iranian archaeologists. In the course of the recent investigationsduring the 2002 and 2009 field seasons, thirty three chalcolithic sites, of which nine sites  contain Dalma sherds, wer...

a nonlocal beam model based on the bernoulli–euler beam theory is presented to investigate the dynamic stability of embedded single-walled carbon nanotubes (swcnts) in thermal environment under combined static and periodic axial loads. the dynamic stability analysis is carried out by including the effects of small-scale parameter, temperature change and elastic medium. the equation of motion is...

The South East region contains a complete ceramic sequence, although overall the distribution of various ceramic styles is varied, with marked concentrations along the coastal regions of Sussex and Kent, and along the corridor of the Thames (Surrey). Since the 1990s the impact of developer funded archaeology has added significantly to the number of known assemblages, although the distribution o...

Introduction Common ragweed (Ambrosia artemisiifolia L.) or simply ambrosia is an annual shrub of North American origin. It has been present in Europe since ~1860 (HEGI, 1908) arriving probably through polluted clover seed grains and hay and straw from North America. Highly infested regions in Europe are the French Rhone valley, the Italian Po valley and some former Yugoslavian states, as well ...

archaeology is growing science that continues to discover the material remains of man; hence, it is the best evidence to understand human relations that too shows close co-operation between the neighboring countries, especially iran and india (present pakistan). right from bronze age when man started building a better social organization, archaeology presents positive evidences for economic an...

In this paper, we propose and evaluate a novel design of a lightly doped drain and source carbon nanotube field effect transistor (LDDS-CNTFET) with a negative differential resistance (NDR) characteristic, called negative differential resistance LDDS-CNTFET (NDR-LDDS-CNTFET). The device was simulated by using a non equilibrium Green’s function method. To achieve this phenomenon, we have created...
