    Results of model calculations of the electron beam divergence parameters for a given yield of DTR photons traversing the slit collimator have shown that the formula proposed in this work can be successfully used as a basis for the development of methods for measuring the divergence of ultrahigh-energy relativistic electron beams based on the angular DTR distributio

    The problem of social orphanhood is one of the most important fmong the social problems of modern Russia, it is acute for a society. In the study of the problems of social orphanage, we used the author’s methods of ranking the regions of Russia according to the dynamics of indicators, an integrated index of “favorable” changes, as well as rating data and indicators of the development of regions of Russia implemented by subjects of social policy and the system of protecting children's rights. Based on the results of the study, the main problems in the social protection of families and citizens in difficult situations are identified. The problems lie in the areas of financial security of social programs, legislative regulation, information support. The results of the study can be used in the activities of social support services. The preventive of social orphanage should be measures of an active social policy

    Determining the divergence of an ultra-relativistic electron beam from the diffracted transition radiation in a single-crystal target

    We have studied the possibilities of using diffracted transition radiation excited by a relativistic electron beam in a single-crystal target to determine the beam divergence. For this purpose, we investigated the expressions we had previously derived that describe the angular density of diffracted transition radiation excited by a relativistic electron beam crossing a thin single-crystal plat

    Effect of the divergence of a relativistic electron beam on the diffracted transition radiation excited by them in a single-crystal target

    The dependence of the angular density and the photon yield of collimated diffracted transition radiation (DTR) generated in a thin single-crystal plate by a beam of relativistic electrons on the beam divergence are studied. An expression describing the DTR angular density averaged over all the rectangular trajectories of electrons in the beam is derived. For the averaging, the two-dimensional Gaussian distribution is used. A significant dependence of the angular density of collimated DTR photons on the electron-beam divergence is shown. An expression describing the number of collimated DTR photons is obtaine

    Among the methodological issues of studying the problem of social orphanhood, an important place is occupied by the search for effective markers for assessing dynamics on the one hand, and the effectiveness of social policy in overcoming social orphanhood on the other. That attempt to systematically evaluate the scale and severity of the phenomenon, as well as the key factors that determine its dynamics. However, these approaches do not allow us to identify the connection between social work and the dynamics of improving the situation with social orphanhood in the region. The presented study proposes a new model for assessing the dynamics of social orphanhood. Its difference from other methodological approaches is that the main emphasis is on assessing the orientation of the complex of shifts in the processes of identifying, placement of orphans and canceling decisions on their transfer to families. This model allows us to assess the role of social policy in overcoming social orphanhood. In this model, we developed authoring methods for ranking the regions of Russia by the dynamics of indicators integrated into the "auspiciousness" index of changes in the social orphanhood. Also, the author presents a model that assesses the situation in the region from the point of view of the "social support efficiency index" to overcome the social orphanhood. The models used to assess the dynamics of social orphanhood have been tested as a tool for identifying key markers of the efficiency of social policy.Entre las cuestiones metodológicas de estudiar el problema de la orfandad social, un lugar importante está ocupado por la búsqueda de marcadores efectivos para evaluar la dinámica, por un lado, y la efectividad de la política social para superar la orfandad social, por el otro. Ese intento de evaluar sistemáticamente la escala y la gravedad del fenómeno, así como los factores clave que determinan su dinámica. Sin embargo, estos enfoques no nos permiten identificar la conexión entre el trabajo social y la dinámica de mejorar la situación con la orfandad social en la región. El estudio presentado propone un nuevo modelo para evaluar la dinámica de la orfandad social. Su diferencia con otros enfoques metodológicos es que el énfasis principal está en evaluar la orientación del complejo de cambios en los procesos de identificación, colocación de huérfanos y cancelación de decisiones sobre su transferencia a las familias. Este modelo nos permite evaluar el papel de la política social en la superación de la orfandad social. En este modelo, desarrollamos métodos de autor para clasificar las regiones de Rusia por la dinámica de los indicadores integrados en el índice de "auspiciosidad" de los cambios en la orfandad social. Además, el autor presenta un modelo que evalúa la situación en la región desde el punto de vista del "índice de eficiencia del apoyo social" para superar la orfandad social. Los modelos utilizados para evaluar la dinámica de la orfandad social se han probado como una herramienta para identificar marcadores clave de la eficiencia de la política social

    Children are the main value of the country, they need care and special attention. The government is obliged to ensure the implementation of children's rights to upbringing, education and development. The family education of children is the priority form. However, there is a problem of orphanage and social orphanage, children left without parental care. There are various forms of placement for orphans. The family form of the placement, foster families, are priority in the world

    Displayed is the review of domestic and foreign literature sources devoted to matters of cholera vibrio cultivation. Discussed is the information concerning the following methods utilized in the technological process of vibrio growth stimulation: batch cultivation, fed-batch, fermentation and dialysis, periodic and continuous cultivation. Analyzed is the impact of such parameters as dissolved oxygen concentration, count of carbon nutrition source, medium pH, temperature rate , concentration and physiological condition of inoculate, duration of technological process, affecting the growth of this microorganism and synthesis of its antigens. Consequently, literature data analysis has contributed to the selection of proper method for cholera vibrio cultivation and consideration of the factors mentioned above for the development of manufacture technology applied to the production of medical immunoglobulin preparations for diagnostics and prophylaxis of cholera
