one of the principal challenges before economical progress and development is governmental monopoly and economical structure. the root of this dilemma is from historical backgrounds and codification our constitution. upon article 44 all of the important economical activities in especial foreign trade belong to the government. but at the end of this article; there is an important clause; it says...

It is shown that using the observed extensive air shower (EAS) electron and truncated muon size spectra at sea level one can solve the EAS inverse problem reconstruction of primary energy spectra and elemental composition, for not more than 2 kinds of primary nuclei. ∗e-mail:[email protected]

Arrival time distributions of EAS muons carry information about the production profile of the EAS muonic component. The measured distributions are affected and distorted by various interwoven effects which arise from the time resolution of the timing detectors, from fluctuations of the reference time and the number of detected muons spanning the arrival time distribution of a single EAS event. ...

Correlates and consequences of newspaper accounts of research on sex differences were examined. In Study 1, articles from high-circulation newspapers were coded for the degree to which biological factors were used to explain sex differences. Results showed that political conservatism and traditional attitudes toward gender roles coded from other newspaper sections predicted greater use of biolo...

The interpretation of extensive air shower (EAS) measurements often requires the comparison with EAS simulations based on high-energy hadronic interaction models. These interaction models have to extrapolate into kinematical regions and energy ranges beyond the limit of present accelerators. Therefore, it is necessary to test whether these models are able to describe the EAS development in a co...
