Authors: Bahari Muhammad Bilal Sulaiman , Gunadhi Albert , Joewono Andrew
Published: November 2020

Barren land can have a social impact on people living in the surrounding area. Land that shouldbe used as dry land is caused by the condition of the land lacking water, so technology is needed thatcan improve the efficiency and effectiveness of water use, namely sprinkler irrigation. This sprinklerirrigation is supported by a big gun sprinkler that is capable of spraying water into the air as far as 20-30 meters, the water distributed can be uniform as rain so that production can be uniform and optimal.This method can take place if the sprinkler big gun that presses 2 to 6 bars is supplied with a waterpump that can provide that much pressure too. This system consists of a DHT22 sensor as an input toread the temperature and humidity values of the air. Arduino microcontroller as input processing fromtemperature and humidity sensors (DHT22) as well as main processing. The output is a water pumpand sprinkler that is used to spray water into the air. There are 3 main modes, namely auto, timer,manual, auto to run the tool automatically and periodically. Timer to run the system with time mode inminutes with a 10 minute increment in stages, manually to run the tool manually which needs to turnon and turn off the pump with the help of human power. The temperature changes carried out by thetool are the fastest with a duration of 3 minutes 42 seconds when the temperature of 33 degrees dropsto 32 degrees Celsius and the longest with a duration of 5 minutes 45 seconds. The most rapid changein humidity is 1 minute 35 seconds when 51 percent humidity rises to 52 percent and the longest with aduration of 3 minutes 1 second when 49 percent humidity rises to 50 percent. In testing the entire toolby running the auto mode the system will automatically turn on when the temperature  value is set and will automatically turn off.

Authors: Saraswati Angela Aneke Putri , Sarah Annisa
Published: November 2020

The wide implementation of fibre optic transmission cable supports the increasing demand of datacommunication, due to its reliability and its fast connectivity. However, optical fibre communicationmight experience an outage condition, which could degrade the overall network performance. Thisstudy analyses an eight months data recording of outage tickets for three region networks by usingTableau. We study three main parameters: age of nodes, device models and the number of tickets thataffect the number of outages in each region. Based on these parameters, we identify the top prioritymaintenance nodes in each region that affect the performance the most. We classified the outagecondition based on internal (e.g. breaker down, maintenance), and external (e.g. electricity blackout,cable bitten by animals). Study shows that most outage causes are the “Electricity blackout” whichaccount of 33.33% of total cases. Meanwhile, the region that suffered by outage the most is Jakarta-Central, with only 99,74% Network Availability (NA), compared to Jakarta-Bekasi-Karawang withNA 99,85% and Jakarta-NorthEast with NA 99,86%.

Вивчаючи контекст появи і шрифти недатованих друкованих послань константинопольського патріарха Єремії ІІ до вірян Київської митрополії, автор приходить до висновку, що вони побачили світ не в острозькій, а у віленській типографії. Це дає підстави слідом за Ігорем Мицьком стверджувати, що між 1581 і 1594 роками книгодрукування в Острозі зовсім припинилося, а всі видання, які за бібліографічними довідниками у цей час мали випускатися в Острозі, насправді побачили світ або пізніше, або в типографії Мамоничів у Вільні. Цей факт дозволяє зрозуміти причини виникнення особливо тісних зв’язків між острозькими книжниками і віленськими друкарями у 80-х роках XVI ст.: через відсутність типографії першим нічого не залишалося, як тільки звертатися за допомогою до других.
On the question of the place of publication of “The Key of the Kingdom of Heaven” by Herasym Smotrytsky

Published: November 2020

На підставі ґрунтовного аналізу 5 шрифтів, які використовувалися для набору «Ключа Царства Небесного» (1587), автор приходить до висновку що пам’ятка, хоч і була підготовлена в Острозі, друкувалася у Вільні. В окреслений період подібна практика не була чимось надзвичайним, і вона засвідчує, що співпраця між двома культурними осередками була щільнішою, ніж досі вважалося.
Project versions of the Ostroh Jesuit College of Architect Giacomo Briano: an attempt to a hypothetical visualization
Authors: Rychkov Petro
Published: November 2020

Дослідження присвячене історії складних відносин поміж княжною Анною-Алоїзою Острозькою (Ходкевич) та архітектором Джакомо Бріано, який на замовлення магнатки мав підготувати проект будівлі для фундованого нею єзуїтського колеґіуму. Непорозуміння між ними призвели до того, що понад десяток креслень було відхилено замовницею. Автор припускає, що суть непорозуміння корінилася не лише в суб’єктивних чинниках. Беручи до уваги увесь доступний масив бріанівської архітектурної графіки, створеної в Острозі протягом 1630-1632 рр., він припускає, що в описуваний період мистецьке та архітектурне середовище Острожчини і, ширше, усієї Правобережної України залишалося у сфері активних впливів православної архітектурної традиції. Слід думати, що навіть для молодої католички видавався неможливим радикальний розрив з мистецькими уподобаннями своїх предків і беззастережне сприйняти стилістичних форм «іноземного» італійського бароко, яскравим адептом якого, власне, і був Джакомо Бріано. Крім того, існував очевидний дисбаланс між явною схильністю виконавця замовлення до архітектурного монументалізму і доволі камерним урбаністичним середовищем Острога, цілковито неспівставним з тогочасними осередками Товариства Ісуса в Західній та Центральній Європі. Врешті, не останнє значення мали обсяги матеріальних та фінансових витрат, необхідних для реалізації бріанівських задумів.

Problems of Subject Retrieval in the Electronic Catalogue of Scientific Library: Review of Studies
Authors: Dovbnya Elena V.
Published: November 2020

Scientific libraries use different approaches and tools for subject retrieval. Issues related to electronic subject retrieval are widely discussed in the library community. The purpose of this review is to analyse publications of recent years on the aspects and problems related to subject retrieval in electronic catalogue (EC). For its preparation, the author used publications (and references to them) taken from the national bibliographic database — the Russian Science Citation Index (RSCI); the time coverage is 2003—2019. Particular attention in the studies is focused on the need to combine different information retrieval languages (IRL), thesauruses, subject headings and keywords to ensure effective and multi-aspect search. Since the domestic libraries have accumulated a lot of experience in indexing and retrieval through hierarchical classifications (UDC and LBC), it is necessary to use this at the full extent in the electronic subject retrieval. The authors of the recent studies on subject retrieval consider being the most effective the functioning of classification systems as part of the complex of linguistic tools of electronic catalogue. In the electronic environment, it becomes possible to use classification indexes as a set of characters that maximally reflect the content of the document, what involves the use of all fragments of the index as independent retrieval elements. However, the lexical composition of the classification information retrieval languages needs to be modified for effective use in the electronic catalogue. The main directions here can be as follows: unification of the structure and vocabulary of classification schedules, optimization of the structure of classification systems (using facetization principles), as well as formalization of the use of grammar tools, (it is necessary to ensure the unambiguity of their interpretation in the electronic catalogue). The review presents and analyses the areas where the subject retrieval has been developed in the electronic environment for over the past 16 years. For example, there has been developed and is being implemented the superstructure over Universal Decimal Classification (Library for Natural Sciences of the Russian Academy of Sciences), which allows users of the library to remotely conduct full-fledged subject retrieval. The paper also presents the new developments by the Russian State Library on subject retrieval, in particular, the project “Presentation of classification metadata of electronic libraries using linked data technology”. The author concludes that it is necessary to form a common space of related open data of various libraries.

Published: November 2020

The article presents an overview of the Bank of ideas of the International Federation of Library Associations and Institutions (IFLA), created in the course of implementation of the “Global Vision” project (2017—2018). The Bank of ideas is designed to host innovative proposals in order to strengthen the influence of libraries around the world. With its help, librarians share their experience and best practices. Everyone can contribute to the formation of collective concept for the development of libraries of the future. Over two years of its existence, more than 30 thousand specialists from 190 countries of the world took part in its formation. The paper emphasizes the importance of this project for the implementation of the IFLA Strategy 2019—2024. The author highlights the priorities of innovative activity of librarians in the following areas: ensuring equal and free access to information and knowledge; supporting of reading and information literacy; meeting the information needs of society; applying digital innovations in libraries; protecting the interests of libraries at the national and regional levels; attracting to decision-making the young professionals who are dedicated to their work and striving for leadership. The author focuses primarily on ideas that may be of practical interest to domestic library specialists. The article marks the role of the Russian library community in the formation of ideas for the development of libraries and implementation of the IFLA “Global Vision” project. The ideas collected through the initiative of librarians around the world should take the form of actions to make the Global Vision a reality. The Bank of ideas is a source of inspiration for strategic and day-to-day librarians’ activities aimed at creating strong and unified library community.
Libraries of Social Organizations of Kazan within the Cultural Environment of the Region in the middle of the 19th — early 20th century
Authors: Abitova Anna V.
Published: November 2020

The range of problems related to the research of regional features of librarianship development has not lost its significance, it urgently requires further consideration. The study of libraries as an integral part of the culture of Kazan and the results of their educational activities will allow identifying and understanding the unique experience of book veneration, national library construction and the culture of book reading in the region, in order to preserve it in the memory of further generations. Identification of patterns and contradictions in the organization of book service in the specific conditions of the national Republic will allow to see the comprehensive picture of the historical-book era from perspective of “library — society”. The author underlines the necessity to streamline and structure scientific information about the libraries of Kazan in the middle of the 19th — early 20th century with a view to its further extraction and use by local historians, librarianship historians and other humanitarian broad specialists in their scientific research.

The phenomenon of libraries of public and social institutions of Kazan is an important page in the regional librarianship. Available publications on the topic cover only some of its fragments. Meanwhile, this component of the regional historical and cultural stratum contains rich material that needs further study and introduction into scientific circulation. The following information, extracted from various sources and being only introduction to the topic, is evidence of this.

The author studied the development of library and educational activities through the prism of libraries of public and social institutions of Kazan. The research material allows concluding that before the Russian revolution there was created a very extensive, though disordered system of libraries of public and social organizations.

The research is carried out on the basis of the Collection for Library Science of the National Library of Russia (NLR), the Department of Rare Books and Manuscripts and the Department of Tatar and Local Lore Literature of the National Library of the Republic of Tatarstan. The author studied the information, reflected in the electronic catalogues of the NLR, the Russian State Library and the Mayakovsky Central City Public Library in St. Petersburg, materials of scientific and practical conferences, publications in professional literature and archival documents. This study summarizes the results of this work. Based on the studied sources, the author revealed the trends of pre-revolutionary library-enlightenment activities as national, cultural and informational heritage of the region.
Implementación del enfoque de competencias en la formación de profesores de secundaria en Chile:
Authors: Quiroz Meza Alonso , Mayor Ruiz Cristina
Published: November 2020

En América Latina, y particularmente en Chile, se observa que los currículos de formación profesional docente están siendo formulados según el modelo por competencias. El objetivo del estudio fue analizar las creencias y disposiciones de los formadores de profesores de matemáticas hacia el desarrollo y evaluación de competencias matemáticas específicas. Mediante una metodología mixta de profundización, se elaboró un cuestionario (validado por juicio de experto y prueba piloto) aplicado a una muestra censal de 56 formadores de 25 carreras de Pedagogía en Educación Media en Matemáticas de Chile, que estuvieran realizando docencia en cursos de primer año de la carrera. La reducción de categorías se realizó mediante el análisis factorial de correspondencias múltiples. Los resultados muestran que los formadores valoran positivamente el enfoque, no obstante, reconocen que la implementación de estrategias de evaluación desde esta mirada ha sido deficiente. Igualmente, ratifican la importancia de la coevaluación y autoevaluación como vías de regulación y autorregulación de los aprendizajes de los estudiantes. Por último, los participantes del estudio coinciden en que las asignaturas que integran saberes como álgebra, geometría, cálculo diferencial e integral, son las que más favorecen el desarrollo de competencias.

Inversión en sistemas hidropónicos: Análisis comparativo de materiales, escalas y sistemas
Authors: Pertierra Lazo Rosa , Torres Carlos , Balmaseda Espinosa Carlos
Published: November 2020

En la provincia de Santa Elena el déficit hídrico permanente, el viento y el ataque de plagas son factores que afectan severamente la productividad hortícola. Los invernaderos de malla sumados al cultivo sin suelo, que permiten un mejor control de las condiciones ambientales y sanitarias, podrían mejorar la rentabilidad del rubro. Localmente la hidroponía es una técnica poco conocida, lo que se suma a la escasez de información al respecto a nivel nacional. Junto con los datos técnicos, de rendimiento y calidad es necesario contar con análisis económicos para proyectar un emprendimiento. El objetivo de este estudio fue generar información sobre los costos de inversión de dos materiales de construcción, dos dimensiones de invernadero y tres técnicas de cultivo sin suelo en hortalizas (pepino, lechuga, maíz). Se compararon los resultados entre los dos tipos de material de construcción (caña de bambú y fierro galvanizado); las dos dimensiones de superficie construida de 105 (15x7x3.5 m) y 1.000 m2 (30x35x4 m); y las tres técnicas de cultivo sin suelo (sustrato inerte, raíz flotante y forraje verde hidropónico). Este último fue el sistema de más alta inversión. La poca diferencia en las inversiones entre los materiales de construcción para ambas dimensiones evaluadas sugiere aconsejar la de metal, porque esta estructura tiene una larga vida útil y no presenta costos adicionales de mantenimiento. Para 10 veces más superficie construida, sólo hubo un aumento de costos cinco veces mayor.
Evaluación del efecto de la fase móvil sobre la eficiencia de separación de la fracción de hidrocarburos aromáticos, obtenida mediante la técnica de análisis SARA.
Authors: Quintero Karla Coromoto , Chacón Génesis S.
Published: November 2020

Esta investigación muestra la influencia de la fase móvil, como variable cromatográfica, sobre la fracción de hidrocarburos aromáticos en una separación SARA, a modo de establecer su impacto en la optimización del proceso de separación. La metodología empleada consistió en realizar 32 separaciones cromatográficas a 32 sub-muestras de maltenos variando la fase móvil para eluir a los hidrocarburos aromáticos entre tolueno, benceno y una mezcla DCM/n-hexano (30:70 v/v). Los resultados obtenidos revelaron que la variación de fase móvil incide en el porcentaje de extracción de la fracción en estudio, en función de la naturaleza del disolvente. Cuando se utiliza tolueno y benceno como fase móvil los resultados son estadísticamente iguales y difieren del obtenido por la mezcla DCM/n-hexano, siendo el orden de extracción el siguiente: tolueno ≥ benceno > DCM/n-hexano, sin embargo, las fracciones de hidrocarburos aromáticos extraídas con la mezcla poseen evidencia experimental de ser más puras que las obtenidas con el resto de los disolventes empleados.

Tuning the Performance of Aqueous Organic Redox Flow Batteries from First Principles
Authors: Yu Junting , Zhao Tianshou , Pan Ding
Published: November 2020

Aqueous organic redox flow batteries have many appealing properties in the application of large-scale energy storage. The large chemical tunability of organic electrolytes shows great potential to improve the performance of flow batteries. Computational studies at the quantum-mechanics level are very useful to guide experiments, but in previous studies explicit water interactions and thermodynamic effects were ignored. Here, we applied the computational electrochemistry method based on ab initio molecular dynamics to calculate redox potentials of quinones and their derivatives. The calculated results are in excellent agreement with experimental data. We mixed side chains to tune their reduction potentials, and found that solvation interactions and entropy effects play a significant role in side-chain engineering. Based on our calculations, we proposed several high-performance negative and positive electrolytes. Our first-principles study paves the way towards the development of large-scale and sustainable electrical energy storage.
On the State and Stability of Fuel Cell Catalyst Inks
Authors: Bapat Shalmali , Giehl Christopher , Kohsakowski Sebastian , Peinecke Volker , Schäffler Michael , Segets Doris
Published: November 2020

Catalyst layers (CL) as an active component of the catalyst coated membrane (CCM) form the heart of proton electrolyte membrane fuel cells (PEMFC). For optimum performance of the fuel cell, obtaining suitable structural and functional characteristics for the CL is crucial. Direct tuning of the microstructure and morphology of the CL is non-trivial; hence catalyst inks as catalyst layer precursors need to be modulated, which are then applied onto a membrane, to form the CCM. Obtaining favorable dispersion characteristics forms an important prerequisite in engineering catalyst inks for large scale manufacturing. In order to facilitate a knowledge-based approach for developing fuel cell inks, this work introduces new tools and methods to study both the dispersion state and stability characteristics, simultaneously. Catalyst inks were prepared using different processing methods which include stirring and ultrasonication. The proposed tools are used to characterize and elucidate the effects of the processing method. Structural characterization of the dispersed particles and their assemblages was carried out by means of transmission electron microscopy. Analytical centrifugation (AC) was used to study the state and stability of inks. Herein, we introduce new concepts, S score and stability trajectory, for a time-resolved assessment of inks in their native state using AC. The findings were validated and rationalized using transmittograms as a direct visualization technique. The flowability of inks was investigated by rheological measurements. It was found that probe sonication only up to an optimum amplitude leads to a highly stable colloidal ink.
Theoretical Study on Proton Diffusivity in Y-Doped BaZrO3 with Realistic Dopant Configurations
Authors: Fujii Takeo , Toyoura Kazuaki , Uda Tetsuya , Kasamatsu Shusuke
Published: November 2020

We theoretically revisit the proton diffusivity in yttrium-doped barium zirconate (Y-doped BaZrO3) with realistic dopant configurations under processing conditions. In a recent study employing the replica exchange Monte Carlo method, the equilibrium Y configurations at typical sintering temperatures were shown to deviate from the random configuration assumed in earlier theoretical studies. In the present study, we took this observation into account and evaluated the effect of the Y configuration on the proton diffusivity. Using the master equation approach based on local diffusion barriers calculated from first principles, the proton diffusivities under realistic Y configurations were estimated to be higher than those in the random configuration. This is explained by the fact that realistic Y configurations have fewer trap sites with deep potential wells compared to the random configuration due to the isolation trend of Y dopants. In addition, the effects of proton-proton interaction and the abundance of preferential conduction pathways are discussed; it is found that both are relatively minor factors compared to the trap site effect in determining the dependence of the proton diffusivity on the Y configurations.
Iron Catalyzed α-C-H Cyanation of Simple and Complex Tertiary Amines
Authors: YIlmaz Ozgur , Dengiz Cagatay , Emmert Marion
Published: November 2020

This manuscript details the development of a general and mild protocol for the α-C-H cyanation of tertiary amines as well as its application in late stage functionalization. Suitable substrates include tertiary aliphatic, benzylic, and aniline-type substrates as well as complex substrates. Functional groups tolerated under the reaction conditions include various heterocycles, as well as ketones, amides, olefins, and alkynes. This broad substrate scope is remarkable, as comparable reaction protocols for α-C-H cyanation frequently occur via free radical mechanisms, and are thus fundamentally limited in their functional group tolerance. In contrast, the presented catalyst system tolerates functional groups that typically react with free radicals, suggesting an alternative reaction pathway. All components of the described system are readily available, allowing implementation of the presented methodology without the need for lengthy catalyst synthesis.

Published: November 2020

A new family of hydrazone modified cytidine phosphoramidite building block was synthesized and incorporated into DNA oligonucleotides to construct photoswitchable DNA strands. The E-Z isomerization triggered by the irradiation of blue light with a wavelength of 450 nm was investigated and confirmed by 1H NMR and HPLC in the contexts of both nucleoside and DNA oligonucleotide. The light activated Z form isomer of this hydrazone-cytidine with a six-member intramolecular hydrogen bond was found to inhibit DNA synthesis in the primer extension model by using Bst DNA polymerase. In addition, the hydrazone modification caused the misincorporation of dATP together with dGTP into the growing DNA strand with similar selectivity, highlighting the potential G to A mutation. This work provides a novel functional DNA building block and an additional molecular tool that have potential chemical biology and bio-medicinal applications to control DNA synthesis and DNA-enzyme interactions using cell friendly blue light irradiation.
Coronaviruses outbreaks — Then to Now

Published: November 2020

According to the World Health Organization (WHO), Viral diseases continue to evolve, posing a significant public health concern. Over two decades, several viral epidemics have been recorded wherein several strains of coronaviruses have been associated with epidemics causing severe respiratory complications and even death. Recently, a novel strain of this virus has come into the picture, eventually leading the world towards a pandemic. The situation today is similar to that witnessed earlier named as “SARS-CoV” and “MERS-CoV” which also affected the respiratory system. Current evidence suggests that SARS-CoV-2 is propagating to humans via transmission from illegally sold wild animals in the Huanan Seafood Wholesale Market. Phylogenetically, it has been shown that SARS-CoV-2 is a new member of the Coronaviridae family and yet is distinct from SARS-CoV (79% identical) and MERS-CoV (50% identical). Knowing the origin of such a pathogen is essential to develop the means to prevent further transmission and effective vaccines. This starts a discussion about the very origin of these viruses that have fanned a global emergency in the name of COVID-19. Therefore, the focus of this review is the origin, evolution and emergence of CoV during “SARS-CoV”, “MERS-CoV” and “SARS-CoV-2” along with possibilities of future outbreaks.

Цель данной работы - уточнить жанровую специфику британских и российских литературных антиутопий. В центре внимания авторов, с одной стороны, жанрово-теоретический анализ утопий, с другой стороны, анализ содержания и структуры базового дуального концепта «Время: настоящее - возможное будущее» и концептов, смежных с ним. Ключевые концепты интерпретируются по процедурам, использующимся в филологической герменевтике. В результате исследования выявлены отличительные особенности британских и российских антиутопий. Аксиологическое основание «британской» дистопии - стабильность и упрощенность, что каузирует застылость в рамках линейного времени. «Российская» дистопия в романе Ефремова основывается на идеях коммунизма, которые оказалось невозможным реализовать. Рассказ Чехова «Пари» строится в традициях «духовного реализма», центрирует внимание на соотношении секулярного и религиозного путей к «совершенному человеку».

The purpose of the article is to clarify the genre characteristics of the British and the Russian dystopian fiction. The work is focused, on the one hand, on the genre and theory analysis of utopias and, on the other hand, on the content and structure analysis of the main binary concept «Time: the Present and the Possible Future», as well as related concepts. The key concepts are interpreted according to the procedures used in the philological hermeneutics. The distinctive features of the British and the Russian dystopias are revealed. The axiological essence of the «British» dystopia is stability and simplicity leading to stagnation within linear time. The «Russian» dystopia in Efremov’s novel is based on the ideas of communism impossible to implement. Chekhov’s short story «The Bet» is based on the traditions of «spiritual realism» and focuses the reader’s attention on the correlation of the secular and religious paths to the «perfect human being».

Authors: Николаева Светлана Юрьевна

В статье рассматривается историософский смысл стихотворения Ю.П. Кузнецова «Федора». Делается вывод о том, что поэт определяет сущность текущего исторического момента в судьбе России в 1993 г., намечает исторические параллели с предшествующими эпохами, вступает в полемику с Чаадаевым и Вяземским, развивает идеи Достоевского и Блока. В центре внимания Ю. П. Кузнецова находится путь России в мировой истории, «русская идея», которая представляет собой не движение по кругу или по кривой, без цели, как считал Чаадаев, не топтание на месте, а осознанное и завещанное предками стояние на своем, поступательное движение вперед через катастрофы и возрождение. Идиостиль поэта подчинен решению этой художественной задачи.

The article deals with the historiosophical meaning of J. P. Kuznetsov’s poem «Fedora». It is concluded that the poet defines the essence of the current moment in the history of Russia in 1993, outlines historical parallels with previous eras, enters into a polemic with Chaadaev and Vyazemsky, develops the ideas of Dostoevsky and Blok. Yu.P. Kuznetsov focuses his attention on way of Russia in the world history, the «Russian idea», which is not a movement in a circle or along a curve, without a goal, as Chaadaev believed, not trampling on the spot, but a conscious and bequeathed by the ancestors insistent movement forward, through disasters and rebirth. The poet’s idiostyle is subordinate to the solution of this creative problem.

The human body cannot make significant required quantities of vital nutrients but fish is minimum-fat, big-protein nutrition that delivers a variety of health advantages. Several external factors including temperature, oxygen level, alkalinity and photoperiod have impact on growth rate while water is also an important parameter in fish rising. Therefore, there is need to work and evaluate impact of fish food and water quality to improve the fish growth. For this purpose, twelve glass aquaria (six with ground water and six with surface water) were considered to assess growth and food conversion ratio (FCR) of Catla Catla and Labeo Rohita and two feeds (i.e. sunflower and bone meal) were provided. The feed has been given twice a day and changed 4% on the rate of body weight of fingerlings in the ground water pond and surface water pond as well. The fingerlings get the most elevated body weight in ground water and on sunflower meal (1.43 ± 0.01 g) as compared to surface water and bone meal (1.39 ± 0.03 g). The general lengths obtained using the fish feed have gotten to be (5.78 ± 0.03cm) on sunflower meal and (5.47±0.03 cm) on the bone meal. The values of FCR had been lower (better) on sunflower meal (2.13±0.01) as compared to bone feast (2.32±0.03). In conclusion, it was observed from the results that fishes fed on sunflower meals had shown better growth with improved morphometric parameters and lower FCR values.

This article is devoted to the systematization and critical analysis of the experience of various countries of the world in organizing the population evacuation from areas of various techno-logical disasters: accidents at radiation-hazardous objects and chemical facilities, as well as dam failures. The article provides an assessment of the role of public notification about the danger, speed and awareness of decision-making by the responsible authorities, prepared-ness of the infrastructure for transportation and resettlement of a large number of people in successful evacuation and minimization of human losses and the number of injured. A distin-guishing feature of technological disasters is the suddenness of the deployment due to the predominant impact of the human factor. In this connection, recommendations are given re-garding the need for preventive preparation of the population and infrastructure for potential disasters in threatened areas.

The present article considers the need to predict migration flows using Predictive Analytics. The Russian Federation is a center of migration activity. The modern world is changing rapidly. An effective migration policy requires effective monitoring of migration flows, assessing the current situation in our and other countries and forecasting migration processes. There are information systems in Russia that contain a wide range of information about foreign citizens and stateless persons that provide the requested information about specific foreign citizens, including grouping it on various grounds. However, it is not possible to analyze and predict it automatically using thousands of parameters. Special attention in Russia is paid to digitalization. Using information technologies (artificial intelligence, machine learning and big data analysis) to forecast migration flows in conditions of variability of future events will allow to take into account a number of events and most accurately predict the quantitative and so-called "qualitative" structure of arrivals. The received information will help to develop state policy and to take appropriate measures in the field of migration regulation. The authors come to the conclusion that it is necessary to amend existing legal acts in order to implement information technologies of Predictive Analytics into the practice of migration authorities.

The article deals with the issues of functioning of the social insurance institution, the organizational-legal and financial forms of which are presented by the state extrabudgetary social funds - Pension Fund of Russia, Mandatory Social Insurance Fund and Mandatory Health Insurance Fund. It considers the main characteristics of social insurance: a) scope of covering the employed population by insurance protection; b) contribution rates as related to wages; c) level of protection of population incomes (pensions and benefits as related to wages and subsistence minimum); d) availability of quality medical assistance and rehabilitation services. There are analyzed the present social risks and problems of the RF insurance system. The main problem is that the amount of financial expenditures on all types of social insurance per beneficiary is about half that of most developed and developing countries. The primary cause is lacking motivation of both employees and employers to participate in the mandatory social insurance and to legalize their earnings. In the conclusion there are formulated a number of proposals for improvement of the institution of social insurance in Russia. It is proposed to expand the range of insurance cases concerning unemployment insurance and care for elderly people, to increase the total amount of compulsory contributions to extrabudgetary insurance funds from 30.2% up to 42.5% from three sources - employees, employers and the state.
