Nonisospectral integrable nonlinear equations with external potentials and their GBDT solutions

Auxiliary systems for matrix nonisospectral equations, including coupled NLS with external potential and KdV with variable coefficients, were introduced. Explicit solutions of nonisospectral equations were constructed using the GBDT version of the B\"acklund-Darboux transformation

International Standards of Penitentiary Activity: Impact on the Development of the Penitentiary Activity of the CIS Countries

Overcrowding in prisons is a common problem that affects many countries. It is difficult to define this term because there is no single internationally accepted standard. This article presents a comparative study of international standards for the activities of doctors in penitentiary institutions as an integral part of international standards of penitentiary activity. The authors investigated the methods and the degree of their impact on the penitentiary legislation of the Russian Federation and other CIS countries. The conclusion is drawn about the positive role of such standards in improving the national penitentiary legislation in order to increase the level of medical care for prisoners

Legal certainty of legality principle in the legislation of the continental and anglo-american system

In this article, through the comparative legal analysis of domestic, as well as foreign constitutional and criminal law norm content, various approaches to the principle of legality and its main features were examine

INVERSE SCATTERING TRANSFORM ANALYSIS OF STOKES-ANTI-STOKES STIMULATED RAMAN SCATTERING

Zakharov-Shabat--Ablowitz-Kaup-Newel-Segur representation for Stokes-anti-Stokes stimulated Raman scattering is proposed. Periodical waves, solitons and self-similarity solutions are derived. Transient and bright threshold solitons are discussed.Comment: 16 pages, LaTeX, no figure

Investigation of oxidation process of mechanically activated ultrafine iron powders

The oxidation of mechanically activated ultrafine iron powders was studied using X-ray powder diffraction and thermogravimetric analyzes. The powders with average particles size of 100 nm were made by the electric explosion of wire, and were subjected to mechanical activation in planetary ball mill for 15 and 40 minutes. It was shown that a certain amount of FeO phase is formed during mechanical activation of ultrafine iron powders. According to thermogravimetric analysis, the oxidation process of non-milled ultrafine iron powders is a complex process and occurs in three stages. The preliminary mechanical activation of powders considerably changes the nature of the iron powders oxidation, leads to increasing in the temperature of oxidation onset and shifts the reaction to higher temperatures. For the milled powders, the oxidation is more simple process and occurs in a single step

Обобщенный опыт изучения и диагностики конвергентных пород на примере карбонатизированных флюидоэксплозивных ультрамафитов дайкового комплекса Среднего Тимана

Fluid-explosive rocks of the dike complex are identified in the Middle Timan. The rocks have convergent properties due to a combination of explosive and metasomatic processes. The study of the petrographic features of the rocks revealed their explosive nature. Further study of the chemical composition of rock-forming minerals established the source of the mantle material and the paragenetic relationship with carbonatite magmatism. The fluid-explosive rocks of the dyke complex have a long-term multistage formation history. The fluids caused fenitization of the host strata and its disintegration. Solid-gas material of the mantle-crustal compound fills the cracks. At the last stage of formation of fluid-explosive rocks, the rare-metal, rare-earth, and sulfide mineralization took place.На Среднем Тимане выделены дайковые флюидоэксплозивные породы с конвергентными свойствами за счет сочетания эксплозивных и метасоматических процессов. Изучение петрографических особенностей пород выявило их эксплозивную природу, а исследование химического состава породообразующих минералов установило источник мантийного материала и парагенетическую связь с карбонатитовым магматизмом. Флюидоэксплозивные породы дайкового комплекса связаны с фенитизацией вмещающей толщи с последующей ее дезинтеграцией и заполнением трещин твердогазовым материалом смешанного мантийно-корового состава. На последнем этапе становления флюидоэксплозивных пород за счет карбонатизации проявляются редкометалльно-редкоземельная и сульфидная минерализации

Limited Sanity in the Legislation of Russia and Europe

This article presents the author’s analysis of the problem of limited sanity in the criminal law theory and practice of Russia and Europe. The author established that the problem of limited sanity, despite its long history, has not yet been developed in many countries, and that the boundaries of the concept of limited sanity are extremely vague and indefinite. However, the experience of some foreign countries in terms of ensuring security measures can be used in the Russian Federatio
