The writer insists that the Bremsstrahlung is possible only, i.e. at negative acceleration of electric charge. Let's consider the elementary case, when t...
متن کاملDeciphering ancient rapid radiations.
A deeper phylogenetic understanding of ancient patterns of diversification would contribute to solving many problems in evolutionary biology, yet many of these phylogenies remain poorly resolved. Ancient rapid radiations pose a major challenge for phylogenetic analysis for two main reasons. First, the pattern to be deciphered, the order of divergence among lineages, tends to be supported by sma...
متن کاملCataracts and avionic radiations.
Nine cases of hertzian radiation cataracts are reported among personnel working in operational aviation environments, where they were irradiated repeatedly at subliminal non-thermal field intensities. The resultant ocular pathology evolved insidiously and slowly over a period of years in a similar way to other forms of radiational injury. By the time of consultation examination, all had progres...
