Determination properties of cast iron used in the installation of anodes

This paper presents the results of determining the cast iron’s properties, which is used in the installation of anodes in the electrolytic production of aluminum. The research methods and applied instruments used for metallographic analysis and chemical composition analysis are described. The results of metallographic analysis of cast iron microstructure “before” and “after” electrolysis are presented. The cast iron’s chemical composition was analyzed by using an X-ray fluorescence spectrometer. The results of experimental melting for testing the casting properties of cast iron for fluidity in a spiral sample are presented

Study of vertebrate animal’s heredity under radioactive contamination

The paper describes the results of cytogenetic analysis of vertebrates for 2013-2015. To study the effect of radioactive contamination on the heredity of vertebrates, a cytogenetic analysis of some vertebrates living near radon sources in Jeti-Ögüz district of Issyk-Kul region was carried out

Complex processing of primary aluminum to remove impurities of non-ferrous metals

The paper presents researches on the complex processing of primary aluminum produced by electrolysis with flux treatment with boron-containing materials and further filtration refining through granular filters. The research methods and applied instruments used for the analysis of the chemical composition and electron microscopy are described. The results are presented before and after the complex treatment of primary aluminum, showing a significant reduction in non-ferrous metal impurities (vanadium, titanium, etc.) and other undesirable impurities

Comrades in Arms: The Military-Strategic Aspects of China-Russia Relations

Within less than two decades China achieved a considerable qualitative leap in capability acquisition and development that allowed the nation to transform its military from being a technologically backward army of peasant draftees into a technologically advanced fighting force. One of the key determinants behind this success story—the Sino-Russian military cooperation and its real extent—has been largely ignored. Yet, the relationship with Russia in the sphere of security and defence allowed the People’s Liberation Army to reduce the capability gap with other regional powers and to launch a strategic push into Southeast Asia and the Indian Ocean region. The current state of Sino-Russia defence relations has not reached a status of a fully grown military alliance. Nevertheless, it has a profound impact on China’s strategic agenda and regional behaviour and has become one of key determinants of regional security in Northeast and Central Asia
