Abstract The natural latex concentrates used for the manufacture of dipped goods, such as gloves, are products both of nature and technology. They are made using the “field” latex obtained from the tree species Hevea Brasiliensis of the Euphorbiacaea family. As the name implies, this tree originates from Brazil but is today most intensively cultivated in the far east (Malaysia, Indonesia, etc.) and in parts of Africa. Nature provides the raw material, field latex, which is then modified, preserved, concentrated, and tested by scientifically developed methods to produce the commercial concentrates. At least 500 000 metric tons, dry rubber weight, of natural latex concentrates are produced annually at present, and this quantity is expected to increase steadily in the future. Field latex can be concentrated by creaming, evaporation, and centrifugation, but the latter method predominates, and this paper will be confined to concentrates obtained by this process. This paper reviews the current situation of NR latex production, the typical properties of centrifuged concentrates, and also presents results of recent research relating to the understanding of the colloidal stability of NR latex.

The monograph presents the search for solutions to the problems of the Far Eastern region. The proximity of China and the remoteness from the center of Russia make us look for effective measures to overcome the problems of settling the Far East in the context of sustainable economic development of modern Russia. The paper analyzes the problems of the Far East: in industry, agriculture, forestry, energy problems, environmental problems, and provides recommendations for their solution. Considerable attention is paid to migration problems. The experience of China is studied through the prism of bilateral cooperation with Russia. It is intended for students, masters, postgraduates, researchers dealing with issues of macroeconomic regulation and forecasting.

Socio-economic indicators of the Irkutsk region, Buryatia and the Far East, dynamics of their development in 2016-2017, and problems and prospects are considered in this paper. Today, the priority for the regions of Siberia and the Far East, which possess unique natural resources and a vast territory, is the complex task of increasing the living standard of the population and launching a new economic strategy. The Irkutsk region is one of the largest industrial regions of Russia. The city of Irkutsk was formed as an administrative, commercial and cultural-educational center. Currently, it is home to more than 50% of the urban population of the Irkutsk region. Some enterprises of the city have a machine-building profile. The production of food (more than 45% of the total volume), the construction material, and wood processing also play an important role. External migration has a significant impact on the demographic situation in the region. Most of the migration processes with the crossing of the boundaries of the region take place within Russia. According to statistical data, external migration can be divided as the three main flows of foreign citizens entering the territory of the Irkutsk region: the Central Asian direction (Uzbekistan, Tajikistan, Kyrgyzstan, and Kazakhstan 44.3%); the East Asian direction (China, Mongolia, DPRK, Japan, and Vietnam 30.8%); and the Western direction (Germany, France, and Poland). It should be also noted that 13.9% of all migrants are migrants from Ukraine, Armenia, Belarus, and Moldova, these are mainly young people of working age. The Baikal region is famous in Russia for its natural landscapes: there are more than 1,500 objects of excursion and cognitive significance (natural, architectural, cultural and historical monuments) in the region. The region has a great industrial potential that is of national importance. Several basic complexes and industries compile a modern industrial structure. There are opportunities for further development of the industrial production in the oil and gas industries, diamond mining industry, the production of composite materials, fibers and mineral fertilizers. On the Far East, priority is given today to the raw material economy and the related infrastructure facilities, including the modernization of the Trans-Siberian Railway and the Baikal-Amur Mainline.

A Quarter of a century has passed since the western world acquired and developed some familiarity with Russian philosophy. The names of Chaadayev, Kireyevsky, Khomiakov and Solovyov are not unknown. The success of the late lamented Nicolas Berdyaev, not only in Europe but also in America and even in the far East, was in large measure due to the fact that his thought continued the tradition created by his Russian predecessors. Ontology, irrationalism, personalism, theohuman nostalgia—such are the themes and attitudes in which lies the originality of this current of ideas.

Pakistan’s textile and clothing industry is one of the significant players of global textile and clothing trade as well as being a corner stone for its national economy. Although Pakistan’s textile and clothing industry possesses abundant raw material resources (cotton) and cheap and abundant labour, it has confronted with many issues in recent years. At this point, SWOT analysis is one of the methods which can be used for the analysis of current situation. This research aims to reveal the present situation of Pakistan’s textile and clothing industry with SWOT analysis. Thus, a gap can be filled in which academic studies are inadequate. Besides, the study contributes to the strategy development of Pakistan’s textile and clothing companies and government executives. In accordance with the aim of the research, the strengths and weakness of Pakistan’s textile and clothing industry are determined primarily. Afterwards, opportunities and threats, which can be faced within national and international textile and clothing trade are analyzed. Finally, the obtained data are analyzed and evaluated and suggestions are made for the future of the industry.

Fisheries of the Far East is the main producer of Russian fodder fish meal, which is used for the manufacture of fish feed in aquaculture. Until recently, the main raw material for this was waste from cutting fish, mainly pollock and salmon. Recently, with the resumption of fishing for sardine-Iwashi and mackerel, fodder flour made from waste from cutting these fish appeared on the market. The article presents the qualitative indicators of fish meal from pollock, sardine-Iwashi, mackerel and salmon. Shown are the results of fish-biological tests of starter feeds made from domestic fish meal for chum salmon in the conditions of the experimental fish hatchery «Ryazanovsky EPRZ» of the Primorsky branch of FSBI Glavrybvod.
