Improvement of system exergy of chemical elements

The article focuses on the fact that the existing systems standard exergies chemical elements are not quite correct thermodynamically, the indicators that are negative values exergies nitrate salts and some other substances. The reason is that the three dominant components of the environment oxygen and nitrogen in the atmosphere and water in the ocean have thermodynamic probability of chemical interaction to form nitrate ion in the ocean. In this paper calculated the equilibrium contents of O2and N2in the atmosphere and the equilibrium concentration of NO3 – -ion in the ocean water, as calculated molar exergies O2and N2 and the air. Shown the air is the holder of the positive exergy and workability, and should not be regarded in exergy applications as ”gift resources”

The effect on actin ATPase of phalloidin and tetramethylrhodamine phalloidin

AbstractActin polymerization has been studied in the absence of excess nucleotide. Using G-actin ATP monomers, it was shown that mechanical shearing stimulates ATP hydrolysis. The procedures used enabled the detection of differential effects of phalloidin and tetramethylrhodamine-phalloidin, on the Pi-release step of the actin ATPase. It is concluded that tetramethylrhodamine, in contrast to phalloidin, accelerates Pi-release from actin filaments

This research contains an up-to-date list of regulatory legal documents of the People’s Republic of China on the topic. The research also presents some aspects of Chinese scientists’ research on environmental impact and accumulated environmental harm

Опыт развития системного мышления у студентов-экологов в рамках курса экоинформатики

The article is dedicated to development of system mentality among students at the base of Ecological faculty of Peoples Friendship University of Russia. This methodological task is partly solved in course of Ecoinformatics, based on the methodology of cognitive modeling and analysis, developed by the group of scientists from the University. The article contains initial student's model and typical modeling mistakes which are clarified.Описан опыт развития системного мышления у студентов экологического факультета Российского университета дружбы народов. Эта методическая задача отчасти решается с помощью курса экоинформатики, базирующегося на методе когнитивного моделирования и анализа, разработанного группой ученых университета. Анализируется пример построенной студенческой модели и основные ошибки моделирования

Topos of Egypt in Poetry of Silver Age

The specificity of the development of the geographical and cultural space of Egypt in the poetry of the Silver Age at the time when the “Russian” poetic Egypt was born as a system of leitmotifs, imagestopos and a specific lexicon is described. It is noted that in modern literary criticism, in comprehending the geopoetics of a regional text, works devoted to the European continent, in particular, geopoetic regional models of Russian literature, have been most fully investigated. The relevance of the study is seen in the need to comprehend and analyze the geopoetics of Egypt and, more broadly, Africa as a sacred geocultural space. The textual fragments of poetic works by K. Balmont, V. Bryusov, I. Bunin, N. Gumilyov, V. Khlebnikov, representing stable geospatial images and symbols of Egypt, are analyzed. The authors come to the conclusion that the poetry of the Silver Age combines geocultural images and symbols with mythological motives, which gives the topos of Egypt a geosophical meaning. The analyzed material made it possible to show the generalized artistic structure of the geopoetic representation of Egypt in the poetics of the Silver Age and to highlight the spatial geocultural dominants: the  Nile, Africa, the desert, the Sphinx, Egyptian heroes as images-topos, the Arab East

Electron Positron Capture Rates and the Steady State Equilibrium Condition for Electron-Positron Plasma with Nucleons

The reaction rates of the beta processes for all particles at arbitrary degeneracy are derived, and an {\it analytic} steady state equilibrium condition $\mu_n=\mu_p+2\mu_e$ which results from the equality of electron and positron capture rates in the hot electron-positron plasma with nucleons is also found, if the matter is transparent to neutrinos. This simple analytic formula is valid only if electrons are nondegenerate or mildly degenerate, which is generally satisfied in the hot electron-positron plasma. Therefore, it can be used to efficiently determine the steady state of the hot matter with plenty of positrons. Based on this analytic condition, given the baryon number density and the temperature, if the nucleons are nondegenerate, only one algebraic equation for determining the electron fraction is obtained, which shows the great advantage of the analytic equilibrium condition.Comment: Accepted for publication in Phys.
