Conventional astronomy spans about 18 decades in photon wavelengths, from 104 cm radio-waves to 10−14 cm γ-rays of GeV energy. Because the universe is opaque to photons of TeV energy and above (see Fig. 1) [1], present studies focus on hadrons, neutrinos, and gravitational waves as messengers probing the high energy universe. The best candidates to serve as messengers in a new astronomy of the ...

this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms) block copolymer modifier used as an interfacial active agent on the dynamics behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian matrix. the results were divided in two sections. the first part included the experiments carried out on the non-modified and 2% block cop...

The present study examine s the relation ship betwe en technology self-efficacy among university students and gender roles. Previous research has based differences in technology self-efficacy on biological sex and found significant differences. University students were asked to complete a survey dealing with gender roles and technology self-efficacy. The current study shows that gender roles, s...

Abstract Symmetries play an important role in fundamental physics. In gravity and field theories, particular attention has been paid to Weyl (or conformal) symmetry. However, once the theory contains a scalar field, conformal transformations of metric can be considered subclass more general type transformation, so-called disformal transformation. Here, we investigate implications pure symmetry ...

cultural iran is a scope that is more extended than the political territories of iran as a political unit. this concept means that cultural geography(mehdi moghanlo-1383-1) of iran is greater than its political geography which, according to history, has a long history extending west-east from kandahar to the euphrates and north-south from the persian gulf to the caucasus including transoxiana a...
