    Giant oscillations of energy levels in mesoscopic superconductors

    Full text link
    The interplay of geometrical and Andreev quantization in mesoscopic superconductors leads to giant mesoscopic oscillations of energy levels as functions of the Fermi momentum and/or sample size. Quantization rules are formulated for closed quasiparticle trajectories in the presence of normal scattering at the sample boundaries. Two generic examples of mesoscopic systems are studied: (i) one dimensional Andreev states in a quantum box, (ii) a single vortex in a mesoscopic cylinder.Comment: 4 pages, 3 figure

    We demonstrate that short laser pulse self-guiding over distances of many Rayleigh lengths can be achieved in the absence of any focusing nonlinearity as a result of trapping of a leaking wave in a plasma channel produced by field-induced ionization in the saturation regime. A detailed computational study of the new self-guiding effect in both cases of comparatively long laser pulses, when the traditional approximation of the slowly varying complex amplitude is valid, and of high intense ultrashort laser pulses comprising only few field cycles have been performed

    BACKGROUND: Human infectious diseases caused by antibiotic-resistant bacterial pathogens present a serious problem for clinical medicine. Causative agents of nosocomial infections, such as Escherichia coli, Klebsiella pneumoniae, Enterobacter spp., are the most common among them. An active search for antimicrobial agents that can effectively combat drugresistant pathogens is underway. Antimicrobial substances of bacterial origin are of particular interest. Promising sources of microorganisms with antibiotic properties are natural sources: Soil, water, plants, etc. AIM: The purpose of this work is to screen and characterize the antagonistic properties of microorganisms isolated from natural sources in connection with the creation of new pharmaceutical substances. METHODS: The material for the isolation of microorganisms was the soil, water bodies, and plant objects of various municipal districts of the Kemerovo Region. Identification of the isolated microorganisms was carried out using the methods proposed in the directory “Bergey’s Manual of Determinative Bacteriology” and in the monograph Nesterenko et al. The selection of strains from soil samples was carried out according to standard methods described in “Methods of soil microbiological control. Methodical recommendations,” cultural-morphological properties of isolates were studied using conventional microbiological methods. RESULTS: The following results are obtained: (1) Lactic acid bacteria and other microorganisms antagonists from natural sources were isolated: Soil, water bodies, and plant objects; 20 isolates were isolated, their cultural and morphological properties were studied; isolated microorganisms were found to belong presumably to the genera Bacillus, Leuconostoc, Pedio-coccus, Lactobacillus, and Bacteroides; (2) Antimicrobial properties of lactic acid bacteria and other antagonistic microorganisms isolated from natural sources on solid and liquid nutrient media were studied; (3) 12 strains of 20 isolates with maximum antimicrobial properties were selected for further studies. CONCLUSION: Further research on the biochemical properties of lactic acid bacteria and other antagonist microorganisms isolated from natural sources, the study of antibiotic resistance of lactic acid bacteria and other antagonist microorganisms isolated from natural sources, as well as other more detailed studies will be conducted with selected 12 strains with maximum antimicrobial properties

    The change in strategic guidelines in Russian education is associated with a revision of the goals of teaching and upbringing. However, the emphasis of reforms has shifted towards the formation of the required professional competences at this stage in the development of the education system of the Russian Federation. We think that it is possible to achieve the set goal of higher education through the development of the introspectiveness as a quality of the personality of students. The formation of the introspectiveness in a future specialist will have an effect on the successful mastery, expansion and transformation of social experience, as well as the internal plan of action. Thus, demonstrating the formed introspectiveness as a personality trait, the student is able to organize his educational activities independently, activities to cognize the surrounding reality and his inner world, as well as self-determine in various life situations, including the development of general cultural and professional competences. In this regard, the emphasis in the issue of developing the introspectiveness of students is made on specifying the conditions that must be created at a higher education institution for the manifestation and formation of this personality quality. The purpose of the article is to study the level of the introspectiveness of university students and develop psychological and pedagogical conditions that develop this personality quality. The leading techniques for the study of this problem were the following: Q-sort Technique; the technique for diagnostics of an individual measure of the introspectiveness degree. At the stage of the ascertaining experiment, the levels of the introspectiveness of university students were revealed. The results of the ascertaining experiment convincingly demonstrated the need to organize special work to develop the introspectiveness of students. The authors substantiated that the success of developing students’ introspectiveness is ensured by the created psychological and pedagogical conditions. A model of developing the introspectiveness as a personality quality of a future professional has been developed and tested. The results of this study create opportunities for further development of the problem in the context of the organization of lectures in the learning process for students of different courses and types of specialization. The article is intended for psychologists, tutors, education managers

    Энергоэффективность применения гибридных тепловых пунктов в условиях интеграции электрических и тепловых сетей городских микрорайонов. Часть 1. Обоснование целесообразности применения гибридных тепловых пунктов

    The paper discusses the circumstances and technical solutions that contribute to the integration of electrical and thermal networks of urban neighborhoods within the framework of a surplus of electricity generating capacities arising from the imbalance in the development of energy generation and consumption, stochastic processes of market economy development, the transfer of energy-intensive industrial production to other countries, the desire to diversify fuel energy resources, passion for the construction of energy sources for alternative energy resources in counterbalance to traditional energy facilities without taking into account all aspects of the interaction of the former with the environment, etc. With regard to district heating systems of electrical and thermal networks of urban neighborhoods, the use of hybrid heating points is achieved, which, unlike standard solutions, are equipped with electric boilers, thermal accumulators and heat pumps. According to the time of use of generating capacities, preference should be given to options for covering the hot-water load. Based on the average daily load, the power usage time in this case lies in the range of 6000–6500 hours / year. When choosing the capacity of the equipment, it should be borne in mind that the daily load of hot water supply is extremely uneven and also depends on the  day of the week, while the maximum load exceeds the average daily by 2.5 – 3.0 times. When integrating electricity and heat supply systems, it is advisable to consider options for only night-time electricity consumption or night-time consumption plus consumption during the hours of daytime failures of the electricity consumption schedule. If during the new construction the power of the electrical network may vary depending on the selected option, then during the modernization of the heat supply system, the problem is solved if there is a limitation on the available electrical power. Therefore, the definition of these restrictions is a separate issue. In comparison with the direct consumption of electricity for the needs of heat supply, which is a priori energetically and economically inefficient, the use of hybrid systems in heat supply allows us to solve the multifunctional task of increasing the reliability of energy supply and the stability of the functioning of the power system, which is primarily achieved by solving the problem of balancing the capacity of production and energy consumption from the position of aligning  schedules of energy generation and consumption.В статье обсуждаются обстоятельства и технические решения, способствующие интеграции электрических и тепловых сетей городских микрорайонов в рамках профицита электрогенерирующих мощностей, возникающего из-за несбалансированности развития генерации и потребления энергии, стохастичности процессов развития рыночной экономики, переноса энергоемких промышленных производств в другие страны, стремления к диверсификации топливных энергоресурсов, увлечения строительством энергоисточников на альтернативные энергоресурсы в противовес объектам традиционной энергетики, без учета всех сторон взаимодействия первых с окружающей средой и др. В системах централизованного теплоснабжения электрических и тепловых сетей городских микрорайонов достигается применение гибридных тепловых пунктов, которые в отличие от типовых решений оснащаются электрокотлами, тепловыми аккумуляторами и тепловыми насосами. По времени использования генерирующих мощностей предпочтение следует отдавать вариантам по покрытию горячеводной нагрузки. В расчете по средней суточной нагрузке время использования мощности в этом случае лежит в пределах 6000–6500 ч/год. При выборе мощности оборудования следует учитывать, что суточная нагрузка горячего водоснабжения крайне неравномерна и зависит также от дня недели, при этом максимальная нагрузка превышает среднесуточную в 2,5–3 раза. При интеграции систем электро- и теплоснабжения целесообразно рассматривать варианты только ночного потребления электроэнергии или ночного потребления плюс потребление в часы дневных провалов графика электропотребления. Если при новом строительстве мощность электрической сети может варьироваться в зависимости от выбранного варианта, то при модернизации системы теплоснабжения задача решается при наличии ограничения по доступной электрической мощности. Поэтому отдельным вопросом является определение этих ограничений. По сравнению с прямым потреблением электроэнергии на нужды теплоснабжения, которое априори является энергетически и экономически малоэффективным, применение гибридных систем в теплоснабжении позволяет решать многофункциональную задачу повышения надежности энергоснабжения и устойчивости функционирования энергосистемы, что, в первую очередь, достигается решением проблемы балансировки мощностей производства и потребления энергии с позиции выравнивания графиков генерации и потребления энергии.
