Detailed analysis of observed antiprotons in cosmic rays
In the present work, the origin of antiprotons observed in cosmic rays (above the atmosphere) is analyzed in details. We have considered the origin of the primaries, (which their interactions with the interstellar medium is one of the most important sources of antiprotons) is a supernova type II then used a diffusion model for their propagation. We have used the latest parameterization for anti...
متن کاملDispersion of Observed Position Angles of Submillimeter Polarization in Molecular Clouds
One can estimate the characteristic magnetic field strength in GMCs by comparing submillimeter polarimetric observations of these sources with simulated polarization maps developed using a range of different values for the assumed field strength. The point of comparison is the degree of order in the distribution of polarization position angles. In a recent paper by H. Li and collaborators, such...
متن کاملreview the position of the ethics paradigm in code of ethics by meta-synthesis –observed case (association for computing machinery )
all researches and documents have a philosophical basis and since paradigm refers to the system of thinking, it can be basis for research patterns. despite of the various discussions on information system paradigms and code of ethics , non of them deal with paradigm of code of ethics. due to this gap the aim of this research is explaining the position of ethics paradigm in organizations code of...
متن کاملobserved and to be observed
Linear defects are generic in continuous media. In quantum systems they appear as topological line defects which are associated with a circulating persistent current. In relativistic quantum vacuum they are known as cosmic strings, in superconductors as quantized flux lines, and in superfluids and low-density atomic Bose-Einstein condensates as quantized vortex lines. We discuss unconventional ...
متن کاملFrequently observed parasites in pet reptiles’ feces in Tehran
Backgrounds Many wild-caught reptiles harbor some kind of parasites. Captivity with negative effect of poor sanitary and husbandry management may lead to clinical disease. The increasing trend in keeping non-native reptile species in the last decade emerged a need for the specification of reptile parasites and their hosts. Objectives The study aims to gain data on intestinal parasites of repti...
