CMB anisotropy data could put powerful constraints on theories of the evolution of our Universe. Using the observations of the large number of CMB experiments, many studies have put constraints on cosmological parameters assuming different frameworks. Assuming for example inflationary paradigm, one can compute the confidence intervals on the different components of the energy densities, or the ...

<p class="Authors">The volumes of world gold mining were reviewed. As a result the analysis, it was found that proportion placer is very insignificant. This due to fact most easily accessible reserves are substantially depleted, and development deposits with complex geological conditions, including those located in Far North, economically impractical. To solve this problem, method propose...
