Static stiffness of curcular saw blades

The article outlines the technique of strain estimating of a band saw blade. The quality of processing depends on the strain character of a band saw rim, improved quality of processing being provided by the saws where the rim is not displaced in opposite directions over the saw perimeter under axial loading

Features of human capital in urban territories

The article is devoted to the peculiarities of the agglomeration processes in Russia that are associated with the transition from the industrial phase to the post-industrial phase of the urbanization. Comparative analysis of results of transition processes in Perm and Yekaterinburg areas is given. Special attention is paid to human capital agglomeration, which is regarded as a component of territorial capital. The calculations of human capital of agglomerated areas in general and of centers of agglomerated areas are carried out. The article contains conclusions on the relationship of human capital as a tangible asset of a big city with the development of specific social capital of the city, aimed at active policy of urbanization. As a theoretical framework it is proposed to use the territorial capital theory.Keywords: urbanization; agglomeration; human capital; territorial capita

Technological characteristics of materials based on metal-containing polymeric wastes produced by seam-forming method

The technological characteristics of materials based on metal-containing polymeric wastes to calculate and optimize the seam-forming process parameters were defined. According to the method of the disk compression between parallel plates, the parameters of the flow law, consistency coefficient, and the exponent were determined. The data on the conditional yiel d strength, coefficient of friction, diffusivity and shrinkage of compositions based on polymer waste were obtained. The effect of the amount of metal-containing wastes on the technological characteristics of the compositions was determined. The level of viscous properties gives the possibility of processing the compositions by the seam-forming method from metal-containing up to 70% polymer waste. The para meters of the conversion process in the product com-positions based on metal-plastic waste by seam-forming method were estimeted. Depending on the geometry and mass of the resulting products the parameters that determine the performance of the process and selection of basic technological equipment were calculate

Современные векторы российской дипломатии на постсоветском пространстве

The countries of the post-Soviet space are of particular importance for Russia’s geopolitical interests. This primarily concerns the political and economic processes taking place in them. Moreover, of great importance are the approaches of the post-Soviet countries to cooperation with Russia and integration processes in the post-Soviet space. In view of significant negative trends in the international arena, the consolidation of the post-Soviet space is acquiring paramount significance. Numerous challenges and complexity of the tasks that Russia is facing in the present region underscore the need for a balanced, pragmatic and forward-looking approach in bilateral and multilateral relations with the states. The focus of Russian diplomacy is still on Ukraine, the countries of the South Caucasus and Central Asia, Moldova and Belarus. These countries are the priority partners of Russia, the priority of its foreign policy.Особую важность для геополитических интересов России представляют страны постсоветского пространства. В первую очередь, это касается происходящих в них политических и экономических процессов. Большое значением имеют подходы стран постсоветского пространства к сотрудничеству с Россией и их позиции в отношении интеграционных процессов на постсоветском пространстве. Ввиду значительных негативных тенденций на международной арене объединение постсоветского пространства, налаживание новых форм сотрудничества и взаимодействия приобретает первостепенное значение. Сложность и комплексность задач, стоящих перед Россией на постсоветском пространстве, подчеркивает необходимость взвешенного и прагматичного, нацеленного на перспективу подхода в двусторонних и многосторонних отношениях с государствами. В фокусе внимания российской дипломатии по-прежнему находится Украина, страны Южного Кавказа и Центральной Азии, Молдавия и Белоруссия. Именно данные страны являются приоритетными партнерами России, приоритетом ее внешней политики

Концептуальные основы политической модернизации в Казахстане

The need to study the experience of political modernization in Kazakhstan is determined by the fact that the modern Russian Federation largely exhausted the inertial potential of the 1990s, trying to build a model of political modernization, which took into account the national (Russian), world (Western) and regional experience of political and social reforms.The aim of the study was to identify the features of political modernization in Kazakhstan. Based on this goal the following tasks were solved:• to define theoretical and methodological aspects of political modernization;• to identify the features of the study of political modernization in modern political science;• to study the basic concepts of political modernization and features of modernization processes in posttraditional societies.To implement the above goals and solve problems were used methods of discourse analysis. That is why the theoretical and methodological basis of the work is based on the methods developed in the framework of studies of political modernization.Необходимость изучения опыта политической модернизации в Казахстане определяется тем, что современная Российская Федерация, в значительной степени исчерпав инерционный потенциал развития 1990-х, стремится выстроить такую модель политической модернизации, которая учитывала бы национальный (российский), мировой (западный) и региональный (включая пример Казахстана) опыт проведения политических и социальных реформ.Цель исследования заключалась в выявлении особенностей политической модернизации в Казахстане. Исходя из поставленной цели в работе, были решены следующие задачи:• определены теоретико-методологические аспекты политической модернизации;• выявлены особенности изучения политической модернизации в современной политической науке в целом;• изучены основные концепции политической модернизации и особенности модернизационных процессов в посттрадиционных обществах, включая Казахстан.Для реализации поставленной цели и решения указанных задач были использованы различные методы научного анализа (системный, институциональный, культурологический). Поэтому в теоретико-методологической основе работы лежат методы, выработанные в рамках исследований политической модернизации

Россия и Грузия: время взаимодействовать

The development of Russian-Georgian relations is determined by both long-term factors and situational circumstances. The former include disagreements between the two countries over security in Transcaucasia: the status of Abkhazia and South Ossetia and the attitude toward NATO activity in the region. Another persistent factor concerns the debate over interaction with Russia in Georgia’s domestic politics. These factors limit the possibilities for expanding bilateral ties. Situational constraints include such phenomena as the COVID-19 pandemic or the domestic political crisis in Georgia after the 2020 parliamentary elections. Taken together, the longterm and situational factors set the general tone for bilateral relations, which are characterized by predictability and low dynamics. Despite the existing limitations, Russian-Georgian cooperation holds promise in areas of trade and societal contacts.Развитие российско-грузинских отношений определяется как долгосрочными факторами, так и конъюнктурными обстоятельствами. К первым относятся разногласия двух стран по безопасности в Закавказье: статусу Абхазии и Южной Осетии и отношению к активности НАТО в регионе. Устойчивый характер имеет и дискуссия по поводу взаимодействия с Россией в грузинской внутренней политикой. Эти факторы ограничивают возможности расширения двусторонних связей. К ограничителям ситуативного характера можно отнести такие явления, как пандемия COVID-19 или внутриполитический кризис в Грузии после парламентских выборов 2020 г. В совокупности долгосрочные и конъюнктурные факторы задают общий тон двусторонних отношений, которым свойственна предсказуемость и невысокая динамика. Несмотря на существующие ограничения перспективным представляется российско-грузинское сотрудничество в торгово-экономической и общественной сферах
