Technology affected human life in many ways in different eras of mankind history. Today, the information and telecommunication technology has revolutionized basic structures of human life. Changes are from the whole to the parts and vice versa, which include family and society too. Family lost its former structure in the information age and differentiated from patriarchy family. Societies have ...

the us hegemony seems to be on decay since the second decade of the twenty-first century. since most of america›s economic and military rivals, are rising from asia, this amazing transition marks a historic re-location of power centers from the west eastward, and the end of western civilization›s domination over global culture and politics, distinguishing this era from previous power transition...

We formulate a gradual dynamical transition from a power-law inflation era with a scalar field to a radiation era with no scalar field including inhomogeneous perturbations to the FriedmannRobertson-Walker universe. We show that for the cosmic microwave background radiation fluctuations this is excellently approximated by a sudden transition, with application of the Lichnerowicz conditions, bot...

the pharmaceutical knowledge and the medical science are very old in iran. during sassanid era, people who studied medicine or pharmacy at gondi-shapour university, had permission to treat sick people. after interruption in the progress of medicine and pharmacy, during the islamic civilization, these sciences were spread and became under control of the government. this research has presented th...

While process technologists are obsessed to follow Moore’s curve down to nanoscale dimensions, design technologists are confronted with gigascale complexity. On the other hand, post-PC and post dotcom products require zero cost, zero energy yet software programmable novel system architectures to be sold in huge volumes and to be designed in exponentially decreasing time. How do we cope with the...

We discuss the creation of massless particles in a Universe, which transits from a radiation-dominated era to any other expansion law. We calculate in detail the generation of gravitons during the transition to a matter-dominated era. We show that the resulting gravitons generated in the standard radiation/matter transition are negligible. We use our result to constrain one or more previous mat...

the scattered stories, due to the way they are put together in the shahnameh, show a thoughtful and systematic pattern and tell more than what they have in their appearance. according to the tradition of the shahnameh research, the book is divided into the following sections: mythical, heroic, and historical. although clear lines do not indicate this classification, the interval and overlapping...
