Determination of Necessary and Sufficient Operational Conditions of The Sleeve-Type Bearings in Autonomous Power Plants of Ormat Type Under Conditions of Siberia and the Far East

The ratification of the Paris Agreement by Russia in 2019 will inevitably force the decarbonization of the Russian electric power industry in future. In this article the potential development scale of low- and non-carbon generation technologies in the Far East power system is considered using MESSAGE optimization model. The required conditions for effective development of new gas-fired as well as nuclear and RES power plants were analyzed, and the potential reduction of CO2 emissions was assessed. The results showed that the development of low- and non-carbon generation technologies in this region requires quite high carbon price or taxes.

Timely Treatment

The human parasitic disease Schistosomiasis is caused by the Schistosoma trematode flatworm that infects freshwaters in tropical regions of the world, particularly in Sub-Saharan Africa, South America, and the Far-East. It has also been observed as an emerging disease in Europe, due to increased immigration. In addition to improved therapeutic strategies, it is imperative to develop novel, rapid, and sensitive diagnostic tests that can detect the Schistosoma parasite, allowing timely treatment. Present diagnosis is difficult and involves microscopy-based detection of Schistosoma eggs in the feces. In this context, we present the 3.22 Å resolution crystal structure of the circulating antigen Serine protease inhibitor from S. mansoni (SmSPI), and we describe it as a potential serodiagnostic marker. Moreover, we identify three potential immunoreactive epitopes using in silico-based epitope mapping methods. Here, we confirm effective immune sera reactivity of the recombinant antigen, suggesting the further investigation of the protein and/or its predicted epitopes as serodiagnostic Schistosomiasis biomarkers.

Synthetic Work

The article focuses on the need to consider classical medieval texts not only as sources of historical information, but also as author's works subject to a certain methodology and using a variety of historiographical technologies and ideological schemes. The specific subject of the study is the two main sources on the history of the Eastern and Western Khitans (“Khitan Guo Chi” / “History of the Khitan state” and “Liao Shi” / “History of the [dynasty] Liao”), who created the largest state structures in the pre-Mongol period. “Khian Guo Zhi” is more of a history of the Khitan ethnos, whereas “Liao Shi” is a history of the dynasty, i.e., of the state construction. As a result, we have the maximum possible penetration in those days into the two most important topics-the people as a geopolitical actor and the state as a civilizational-state structure. Their authors carried out impressive synthetic work to prove certain postulates. These are, strictly speaking, not scientific approaches, but ideological, existing, moreover, often in the form of Philistine fabrications. These sources raise a particularly significant problem of the origin of the Khitan, their dynasty, civilizational affiliation of the Khitan, the Khitan determination of the place in a nomadic world, the specifics of socio-economic and social system of the state of Liao, Khitan influence on the social development of the far East and East Asian regions. In them, the Chinese civilizational paradigm was applied to the fullest extent possible, the essential worldview settings of classical Chinese historiography are traced: Sino-centrism, sedentary centrism, Han-fan dichotomies and culture – nature. As a result, these works had a significant impact on the development of the two most common approaches to studying the history of Khitan, which are considered as classical barbarians who constantly attacked China and for this purpose created their own quasi-state, but under the influence of Chinese civilization “grew” to the level of the traditional dynasty.

The Standard Technical Documentation (STD) of The Association of Mechanical Engineers (A.M.E.), Section III “Strength Assessment of Equipment and Piping of Nuclear Power Plant of VVER type” provides guides and requirements for elaboration of: - conclusive documentation for equipment, piping and their supports, manufactured and supplied or manufactured for replacement, for nuclear power plants of VVER type, 440 MW and 1000 MW; - conclusive documentation for repaired, replaced and innovated components of equipment, piping and their supports for nuclear power plants of VVER type, 440 MW and 1000 MW; - conclusive documentation on continuous lifetime usage of equipment, piping and their supports during the operation of nuclear power plants of VVER type, 440 MW and 1000 MW and determination of their residual lifetime; - documentation on degree of compatibility of equipment, piping and their supports for nuclear power plants of VVER type, 440 MW and 1000 MW with the ASME Code Section III, Division 1. The following principles of the Section III are discussed in the presentation: general structure of the Section III; design specifications and operational conditions; calculation of allowed stresses; stress categories groups (σ)1, (σ)2, (σ)R, and (σaF); limit criteria for stress categories groups; loading blocs; assessment on fatigue; assessment of two-frequency cyclic loading on fatigue; fatigue correction factors for multiaxial stress states and gradient of stresses, corrosion, welding and radiation; limits; determination of load at collapse; use of elastic and elastic-plastic analyses; elastic-plastic carrying capacity of components; stiffness of the nozzle opening.

Professional Self

The article deals with the features of professional self-determination of schoolchildren in years 8–10 of Arctic and Russian Far East regions. The study revealed factors that influence the choice of future professions by schoolchildren; generalized schoolchildren’s ideas about the category of “profession” and its content; analyzed ideas of schoolchildren about their professional future; considered the interests of schoolchildren in building a successful career in the Arctic and Russian Far East regions. The results obtained showed that schoolchildren are more oriented towards higher education, and their chosen professions are in demand in the Arctic and Russian Far East regions where there is a deficit of qualified personnel. The students are optimistic about their professional future, and they also positively assess the opportunities of starting a career with Arctic and Far East companies. Every tenth pupil from Arctic regions and every fifth pupil from the Far East regions noted that they had planned professional implementation in these regions earlier, almost every third pupil was interested in it, but they are not sure that it suits them. The results of the research may be useful in planning themed career guidance activities aimed at involving young people in strategic regions of the country, and useful for career guidance specialists, educators, relevant authorities and researchers.
