Published: December 2022

The study aims to examine the Regional Head authority in the regional autonomy and to investigate the authority relationship between the Regional Head authority and his Deputy from legal and political perspectives. This study employed a doctrinal research method involving legal material sources (the laws and regulations), court decisions/judgments, legal theories, and scholars' perspectives. The findings revealed the Regional Head authority is clearly stated in Article 65 of Law Number 9 of 2015 concerning Regional Government, such as to lead the implementation of government affairs–the regional authority based on the laws and policies established with the DPRD, to maintain public peace and orderliness, and to compile and to submit regional regulations draft. Normatively,  the Regional Head and his Deputy have their respective duties, the authority relationship. In this case, the Deputy Regional Head assists the Regional Head in the governance to acquire the fullest services for the community. In short, in terms of authority, the Regional Head is an extension of the President-- the full holder of goverment power. In terms of the authority relationship, different opinions between the Regional Head and his Deputy are frequently occurred as in the political views

Published: December 2022

Success in eradicating corruption can not only be judged by simply bringing the perpetrators to justice. This success is deemed insufficient if the state losses due to corruption committed cannot be recovered, so that success is considered sufficient, it must be able to confiscate the assets of the accused perpetrators of corruption in the trial, which will later be used as payment of compensation for state losses charged to the Defendant. With the reason for the payment of compensation for state losses, the Defendant's property was then confiscated, both used and obtained from a criminal act of corruption, as well as on the Defendant's property which was obtained not from a criminal act of corruption and has nothing to do with a criminal act of corruption. Corruption crimes examined in this study include corruption cases in the field of natural resources, there are several court decisions in natural resource corruption regarding replacement money. The purpose of this study was to determine the position of the evidence in the trial process and how the legal protection of the defendant's property was used as evidence in the corruption case. This research is descriptive, normative juridical research type through legislation and conceptual approach, using secondary data obtained through literature study and document study, then analyzed qualitatively. The conclusion of this study are that the principle of presenting evidence in court is to support the evidence of the defendant's actions, not to be used as collateral for the execution of the sentence, so that the defendant's property that is not related and is not the result of a criminal act of corruption cannot be used as evidence in court process;

Introduction. The compartments of a ship or submarine are a closed system in which the development of fire parameters can be assessed and predicted by monitoring the gas pressure and the rate of its change. However, the question of the effect on the accuracy of such estimates of the process of gas flowing from the emergency compartment to adjacent ones in the presence of hole between them, that is, in conditions of incomplete sealing of the emergency compartment, remains unclear. Aims and purposes. The goal of the study is to develop a model of the process of air flowing through a hole in a closed system of two compartments with a certain initial pressure drop, as well as computational methods for estimating the pressure equalization time and the minimum (critical) area of the hole between the compartments, at which the equalization process occurs almost instantly. Methods. To estimate the rate of gas flow between compartments, it has been proposed to use the equation of the adiabatic outflow of gas from a large volume with some initial overpressure through the hole, obtained on the basis of the transformation of the Bernoulli equation. The equation has been transformed taking into account the fact that the density of the flowing gas is approximately the same at all sections of the outflow process. This assumption is justified by the fact that during a fire in a closed volume, an increase in excess pressure occurs not due to an increase in the density of the medium, but as a result of an increase in its temperature. Results and discussion. As a result, a new differential equation has been obtained, the integration of which made it possible to obtain an analytical expression for calculating the pressure equalization time depending on the initial pressure drop, the area of the hole and the volumes of the compartments. All other things being equal, the dependence of the alignment time on the ratio between the volumes of the compartments is parabolic, reaching a maximum when these volumes are equal to each other. The gas flow model and the resulting equations have been verified and confirmed experimentally. The relative error does not exceed 20 %. Conclusions. The developed model and the equations obtained at the same time allowed us to propose a methodology and calculation formulas for estimating the critical value of the opening area between compartments, at which the equalization time is negligible, and there is no need to control the air pressure in each of the adjacent compartments, for example, to diagnose the parameters of fire development. Keywords: closed system of adjacent compartments, gas flow through the hole, pressure equalization time, critical area of the overflow hole.

On the basis of observational and reanalyzed data containing more than 60 years of time series, the authors studied climate changes and inter-annual variability of river flow, precipitation, soil and atmospheric moisture in the White Sea region. As an object of study, they consider the White Sea region — a territory that includes a square within 61°—70° NL and 30°—46° EL. The authors used open resources of Roshydromet, as well as various reanalysis data. For all the studied rivers of the White Sea catchment area, there are positive trends in the change in their flow (on average 11% for the period 1955—2019). This may be due to the observed increase in precipitation in the region over the same calculation period. A significant increase in precipitation has been established since the mid-1970s until 2021. Changes in the amount of precipitation in the White Sea area over the period of satellite observations (1980—2021), estimated by a linear trend, are unevenly distributed. In the northeast and southwest of the region under consideration, there is a decrease in average daily precipitation by –0.02 kg/m2 over 10 years. This decrease is several times less in absolute value than the increase in precipitation in the central part of the study area — by about +0.06 kg/m2 over 10 years. As a result, there has been an overall increase in precipitation throughout the region. The study shows that this growth is most pronounced in the areas of Kandalaksha and Dvina Bays, as well as in the catchment area of the Northern Dvina River. The authors assume that the observed increase in precipitation may be due to the increased influence of the North Atlantic and the Arctic Ocean on the White Sea region. The performed spectral and wavelet analysis revealed fluctuations in the studied parameters with periods of 2—4 years and 12—14 years. Via cross-wavelet analysis, the authors show the relationship between the inter-annual variability in the amount of precipitation in the White Sea region and the North Atlantic and Arctic oscillations.

The Pechora Sea is an essential region of the Russian Arctic shelf in terms of hydrocarbon production and cargo transit along the NSR (mainly from the Ob’ Bay area). Occasionally, heavy ice conditions form in this area, manifested in the compression of the ice cover, which lead to a serious complication of navigation and operation of vessels supporting the Prirazlomnaya ice resisting platform. Based on the analysis of various sources, the authors consider the processes of formation of severe ice conditions in 2003 and 2018, as well as their impact on the operation of ships. They demonstrate that the only vessel able to operate steadily in such conditions is a nuclear icebreaker. The authors suggest that ice compressions of varying intensity are quite typical for the area and can repeat occasionally

The authors consider the mining-geological and technical-economic conditions of promising ore deposits in the Western part of the Arctic of the Russian Federation and analyze the existing methods for evaluating investment projects. They have revealed that the methods do not take into account the intensive introduction of digital technologies, automation and robotization of machines and equipment into the mining industry. The authors substantiate the necessity of using digital technologies in the investment appraisal of mining projects. The study objective is the developing of an improved method for investment appraisal in the Western Arctic mining projects. The authors suggest a methodical approach based on parametric and scenario modeling, which allows minimizing the influence of uncertainty factors and increasing the efficiency of decision-making. Thus, for the practical implementation of the approach in the investment appraisal of mining projects, taking into account digital technologies, they propose an algorithm that includes six effective steps. A distinctive feature of the approach is the use of methods for modeling mining equipment objects. The mining and geological information system MINEFRAME, created at the Mining Institute of the KSC RAS, has the necessary functionality. An investment appraisal of 13 promising deposits as mining projects is completed. The authors select nine (9) deposits that best meet the criteria of economic feasibility. Types of ore minerals: titanium, rare earth elements, lithium, vanadium group the selected deposits and ranked according to investment evaluation indicators. The authors propose economically justified and effective scenarios for involving investment-attractive deposits in the economic turnover. Both the integration of mining projects into closely located mining enterprises and their autonomous development are envisaged.

Циркониевая керамика обладает высокими функциональными и прочностными свойствами. Области ее применения постоянно расширяются. Использование нанопорошков позволяет получить мелкозернистую керамику с улучшенными свойствами. Диоксид циркония обладает высокой твердостью, что вызывает повышенный износ пресс-форм. Кроме того, наночастицы склонны к агломерированию, что влияет на уплотнение при компактировании и спекании. Данные проблемы можно решить путём введения микродобавок. Одной из таких добавок является углерод. Целью настоящей работы является исследование влияния вида добавки углерода и его концентрации на параметры циркониевой керамики из порошкового сырья, полученного золь-гель и плазмохимическим методами. Методом дилатометрии была исследована усадка образцов двух типов керамики с тремя типами добавки углерода, представляющие из себя многослойные углеродные нанотрубки (МУНТ), аморфный углерод, а также аморфный углерод с присутствием МУНТ. Определено, что введение добавки не оказывает влияния на скорость усадки, и наибольшая скорость усадки образца практически не отличается от таковой для спекания керамики без добавок. Определено влияние добавки углерода на плотность и микротвёрдость керамики. Введение добавок в керамику, из порошков, полученных по золь-гель технологии, вызывает снижение плотности и микротвёрдости, в то время как плотность керамики из плазмохимических порошков увеличивается до некоторого порогового значения концентрации добавок, что справедливо для всех типов углерода, рассмотренных в данном исследовании.

Настоящая работа посвящена исследованию влияния «токовой» неустойчивости упрочнения элемента деформационной среды на локализацию деформации на разных масштабных уровнях. Термин «токовая неустойчивость» взят из характеристики токовой неустойчивости электропроводности полупроводников в сильных электрических полях, имеющей характерную кривую ток-напряжение (I-U) [1]. Аналогичная форма кривой упрочнения элемента среды деформирующее напряжение-деформация (σ-ε) рассматривается как причина локализации деформации. Рассмотрены и моделируются явления локализации деформации, вызванные «токовой» неустойчивостью различного вида. Показано, что сценарий пластического течения при «токовой» неустойчивости, заложенный на уровне микроэлемента среды, может проявляться на макромасштабном уровне пластического течения в виде локализаций различного вида. Моделирование проведено на основе конечно-элементной двухуровневой модели, предложенной ранее авторами статьи [2]. Рассмотрены случаи, когда в зависимости от вида кривых упрочнения элементарного объема деформируемого образца, описывающих «токовую» неустойчивость, на макроуровне наблюдается либо «устойчивая», либо «бегающая» шейка при одноосном растяжении образца.

Лазерный метод прямого испарения углеродных мишений в интервале энергий лазерного излучения 4-6 Дж позволяет получить парогазовую фазу углерода с преимущественной sp3-гибридизацией электронов. В ходе конденсации такого углерода на аморфную подложку из силикатного стекла осуществляется поатомная сборка тетрагональных алмазоподобных кластеров в виде двумерной пленки, в которой концентрация графитоподобных кластеров, сформированных углеродом за счет sp2-связей, существенно ниже. То есть структура такой пленки представляет собой композиционный материал, в котором свойства композита будут зависеть от соотношения алмазоподобной и графитоподобной фаз. Проведенные исследования структурного состояния углеродных алмазоподобных пленок подтверждают наличие как алмазоподобных, так и графитоподобных кластеров размером не более 1 нм. Электронная микроскопия надежно фиксирует тетрагональные (алмазоподобные) кластеры. Дифракция электронов свидетельствует, что кристаллографические параметры – межплоскостные расстояния плоскостей (111) и (220) d111=0,207 нм, d220=0,119 нм примерно соответствуют алмазным, равными соответственно для крупнокристаллического алмаза d111=0,205 нм и d220=0,125 нм. Если электронная микроскопия не позволяет зафиксировать графитоподобные кластеры в структуре пленки, то Раман-спектроскопия, фиксирующая G-пик около 1600 см-1и D-пик, так называемая D-мода из-за разупорядочения в графите (disorder peak). Линия около 1393 см-1в спектрах комбинационного рассеяния света, идентифицирует наличие графитоподобных кластеров с разупорядоченной укладкой графеновых плоскостей.

Сплавы титана с золотом рассматриваются как перспективные для применения в стоматологии за счет их высокой твердости и биоинертности, однако данные по влиянию их состава и методов изготовления на функциональные свойства довольно ограниченны в настоящее время. С целью восполнения этого пробела, в данной работе были синтезированы шесть сплавов Ti-Au путем сплавления двух титановых пластин и тонкой золотой фольги между ними пропусканием униполярных импульсов электрического тока (процесс аналогичный контактной точечной сварке). Импульсы отличались длительностью заднего фронта на завершающем этапе процесса, так как основная цель заключалась в исследование влияния скорости охлаждения металла на микроструктуру и механические свойства формируемых сплавов. Микроструктура была исследована методом оптической микроскопии, распределение микротвердости определяли наноиндентированием модифицированной пирамидой Берковича, распределение химических элементов было определено с помощью растрового электронного микроскопа, оборудованного энергодисперсионным спектрометром с последующей статистической обработкой полученных данных. Наиболее равномерное распределение золота и максимальная средняя микротвердость металла литого ядра, а также высокая прямая корреляция между этими параметрами были достигнуты при имплементации режима с наибольшей длительностью охлаждения. Во всех исследованных случаях была обнаружена неравновесная литая микроструктура, состоящая из двух фаз: твердого раствора α-Ti(Au) и интерметаллидов AuTi3, причем участки интерметаллидных включений, обладающие повышенной микротвердостью, были распределены по объему достаточно равномерно. На основании полученных результатов был сделан вывод, что представленная методика формирования и исследования сплавов является эффективным методом, позволяющим изучать металлургические процессы, протекающих в условиях высокоэнергетических воздействий, а также в лабораторных условиях разрабатывать наиболее рациональные термические циклы для их последующего внедрения в реальных промышленных технологиях.

Работа посвящена исследованию влияния комплексного легирования алюминиевых сплавов магнием, марганцем, скандием, цирконием и гафнием. С этой целью в стальной кокиль были отлиты слитки А85, а также сплавы систем Al–Mg, Al–Mg–Sc, Al–Mg–Mn–Sc и сплав 1570 в том числе с добавками гафния 0,5 %. У всех сплавов изучена зёренная структура, интерметаллидные включения и механические свойства. Для сплавов 1570 и 1570–0,5Hf дополнительно на просвечивающем электронном микроскопе изучались наночастицы типа Al3(ПЭ1x, ПЭ2(1-х)). Анализ зеренной структуры показал, что увеличение содержания магния, а затем марганца, а после добавки скандия (до 0,3 %) постепенно снижают размер зерна. Однако в целом зёреннная структура остается дендритной. Равноосная структура появляется лишь при комбинированном скандиево-циркониевом легировании, а добавки гафния позволяют добиться её дополнительного измельчения. При увеличении содержания легирующих элементов растет количество крупных интерметаллидных частиц, формирующихся при кристаллизации. Необходимо отметить, что во многих крупных неравновесных частицах содержится большое количество скандия и циркония. Добавки гафния уменьшают количество скандия и циркония в крупных интерметаллидных частицах, повышая их содержание в пересыщенном твердом растворе. Рост содержания мелкодисперсных частиц, образующихся при остывании слитка, наблюдается лишь после комбинированного скандиево-циркониевого легирования в результате прерывистого распада. При добавлении гафния выпадение наночастиц из пересыщенного твердого раствора при остывании слитка практически прекращается. Механические свойства в литом состоянии вначале растут вследствие твердорастворного упрочнения и измельчения зерна, а затем за счет появления частиц типа Al3(Sc,Zr).

Проанализировано влияние всесторонней изотермической ковки (ВИК) на формирование ультрамелкозернистой (УМЗ) структуры применительно к титановым и жаропрочным никелевым сплавам. По результатам исследования показано, что в процессе ВИК исходная крупнозернистая структура в никелевых сплавах ЭП741НП и ЭК61 с различным типом упрочняющей фазы Ni3(Al, Ti) и Ni3Nb соответственно трансформируется в УМЗ структуру дуплексного типа с размером зерен матрицы (g-фазы) для ЭП741НП около 0,6 мкм, для ЭК61 около 0,3 мкм, а в титановом сплаве ВТ22 до размера около 0,38 мкм. Микротвердость после ВИК увеличилась на 5 % для сплава ВТ22, на 10 % для сплава ЭП741НП и на 34 % для сплава ЭК61. Создан научно-технический задел для оптимизации технологических режимов получения УМЗ структуры дуплексного типа в массивных объемных заготовках, в частности, применительно к никелевым сплавам (ЭП741НП и ЭК61) и титановому сплаву ВТ22, необходимый для последующей обработки сплавов в режиме низкотемпературной сверхпластичности.

First proposed in 2000, cardio-oncology bears the mission to reduce cardiotoxicity whilst successfully treating cancer. Through two decades of development, substantial progress had been made in determining the specific clinical symptoms, mechanism of action, ways of monitoring, and toxicity reduction of the cardiotoxicity induced by cancer-related treatment. By summarizing the progress in cardiotoxicity induced by targeted cancer therapy in the past two decades, this mini-review aims to give some enlightenment on the fundamental research of cardio-oncology.
Digital transformation of the economy at the regional level: strategy and specifics
Authors: Avramchikova N. T. , Rukosuev A. O.
Published: December 2022

The article defines the concepts of strategic planning, digitalisation, digital transformation in relation to public administration. The specifics of digital transformation in this field at the regional level are analyzed and an assessment of the effectiveness of the implementation of its components is made. The authors note that the direct use of foreign models of strategic planning in the field of digital transformation is problematic in Russian practice, since they do not consider the specifics of the Russian economy associated with the weak economic development of territories. It is concluded in the text that it is necessary to create a system of state strategic planning that takes into account these features. Disadvantages of strategic planning of digital transformation are investigated, mechanisms of research of typical errors are studied. The basis of this research was the analysis of strategic attitudes in the field of digital transformation of business processes and social interactions of the Krasnoyarsk Krai of the Russian Federation. A critical assessment and completeness of the methodological provisions of the federal project Digital Public Administration is carried out, the positive and negative aspects of this document are investigated. The article assesses its impact on the digital transformation in public administration in the Krasnoyarsk Krai. The authors reveal the inconsistency of goal-setting with the idea of digital transformation, the lack of alignment of relations between stakeholders, the low methodological study of the issue and the insufficient assessment of regional specifics. It is concluded that at present the digital economy development strategy is not fully provided with the necessary amount of funding and does not reflect the needs of strategic planning of digital transformation in the public administration system.
Scientific approach to the study of the digitalization impact on the regional economy
Authors: Chistnikova I. V. , Antonova M. V. , Mikhailichenko M. I.
Published: December 2022

The authors of the article test the hypothesis about the impact of digitalisation processes on the level of territories’ economic development. This hypothesis is based on the fact that in the Russian Federation digital transformation is considered as a conceptual model for improving the activities of intraregional economic units and the development of modern society, as well as a factor of economic and social breakthrough. The purpose of the study is to develop scientific and methodological support for the territories’ transformations management based on digital transformation. Systematization and generalization of methodological approaches to the assessment of digital transformation in the region have been carried out. For this purpose, a scientific approach to the design of indicators system characterizing the processes of digitalisation is proposed. To test the approach, a correlation analysis of the current state of digital development impact on the territories’ economic results was carried out. The analysis of the statistical dependence between the development and welfare level of Russian regions and the parameters of their digitalization showed a low (moderate) relationship. This means that with the current volume of funding for digital transformation and the use of information technologies, devices and special software, it is impossible to ensure the breakthrough development of regional economic systems and their production complexes.
Possibilities for forming a new model for the development of Russia’s military-technical cooperation with foreign countries under the conditions of sanctions and current geopolitical risks
Authors: Repnikov D. A.
Published: December 2022

International economic relations at the beginning of the 21st century are experiencing a new reality, when many world economy achievements of the globalization era are being reversed, and the entire system of economic cooperation between the countries is undergoing revolutionary changes. In this context, there have been significant shifts in the structure and trends of militarytechnical cooperation between Russia and foreign countries, when the existing strategic approaches to the organization of this process are being radically modified. The article shows that the main narratives of these changes are the unprecedented strengthening of anti-Russian sanctions, which caused a change in the methods of foreign economic policy, which significantly affected the development of the military-industrial complex, the strategy for realizing its export and investment potential. In this regard, the issues of sectoral import substitution, diversification of the defense industry, formation and implementation of the state defense order in this sector of the national economy are becoming highly controversial and complex. The ever-increasing deepening of cooperation and integration ties with partners from developing countries and the actual curtailment of these ties with developed countries is a strategic long-term task designed to ensure both the development of the defense industry and the elimination of existing geopolitical risks. At the same time, within the framework of the defense industry strategy, it is still difficult to call the task of prompt response to new emerging risks solved, and this aspect should underlie the new model of Russia’s military-technical cooperation with foreign countries.
