Published: September 2023

An algorithm for noise suppression and extraction of coherent structures of a complex signal is proposed. The algorithm is based on the joint application of packet wavelet decompositions and adaptive stochastic thresholds. Thresholds are estimated with a given confidence level based on the α-quantiles of Student's distribution. The operations of the algorithm are described and a scheme for its implementation is proposed. On the example of data from neutron monitors (recording the intensity of secondary cosmic rays, www.nmdb.eu), the efficiency of the algorithm is shown. The selected coherent structures characterize the occurrence of anomalies in variations in the intensity of cosmic rays. Anomalies in cosmic ray data create a radiation hazard, disrupt radio communications, and cause satellites to malfunction, leading to disorientation and destruction. Therefore, the task of timely diagnosis of such events is relevant. The application of the algorithm made it possible to clearly detect and evaluate the moments of occurrence of anomalies in cosmic rays, which were observed during periods of magnetospheric disturbances.

Published: September 2023

This work is devoted to the development of a simulation model of a voltage drop compensation device containing an electric energy storage device. The proposed control algorithm makes it possible to minimize the shock moment and the current surge of the motor when transferring the load in the event of an emergency. The control system considered in the work implements an algorithm for automatic phase matching of the EMF of the motor and the voltage of the inverter, which allows soft switching function transferring the load from one power source to another. In this case, the electric voltage angle of the inverter is phase-consistent with the decrease EMF of the motor. The calculation of EMF with the allocation of amplitude, phase and frequency is carried out with the help of an observer developed by the authors. As a result, a workable simulation model of a high-speed automatic reserve input device with an energy storage device was obtained. In conclusion, the authors cite transients that confirm the operability of the proposed approaches.

The purpose of the research is to conduct a comparative analysis of the First World War and the current Russian-Ukrainian war based on the use of mass media materials, statisti- cal data, testimonies of contemporaries in various forms and popular science works published on the eve of and during these armed confl icts. Th e research methodology is based on the prin- ciples of historicism, objectivity, systematicity and the use of universal general scientifi c research methods (analysis, synthesis, induction, deduction) and special-historical and interdisciplinary methods (historical-comparative, historical-genetic, statistical). Th e scientifi c novelty is that, for the fi rst time in national historiography, historical parallels between the First World War and the current Russian-Ukrainian wars have been drawn in the international and domestic Ukrainian context. Conclusions. In 2022, as a result of the successful defensive and counter- off ensive actions of the Ukrainian troops and clear signals from the US and European states regarding the full support of Ukraine, materialized in fi nancial and armed aid, hopes for a quick victory over the aggressor appeared in our society, regardless of its huge material and human resources. However, at the end of the year it became clear that the desired victory would not be achieved in the near future. Th erefore, the key to the protection of the Ukrainian state is nation- wide strategic patience, contrary to the harmful national tradition of internal political discord in diffi cult times. So, similar to the war of 1914-1918, the outcome of the current armed confl ict will largely be decided on the “internal front”. However, in contrast to the wartime 100 years ago, when a universally understood ideology of war was never formed, the current Ukrainian- Russian confrontation does not have this problem.
Religious factors in the formation of the Ukrainian national movement at the end of the xix – in the first decades of the xx century: the role of the orthodox and greek-catholic clergy
Authors:   Berdyansk State Pedagogical University, Fedoryk Yuriy
Published: September 2023

The purpose of the article is to study the role of the Orthodox and Greek Catholic clergy in the formation of the Ukrainian national movement at the end of the 19th – in the fi rst decades of the 20th century and determine the infl uence of religious factors on the development of Ukrainian national identity. Th e scientifi c novelty of this topic lies in an attempt to compare the infl uence of the leading Eastern Christian faiths on the formation of Ukrainian national identity at the end of the 19th and the beginning of the 20th centuries. Th is topic focuses on the importance of the religious sphere in forming the Ukrainian people’s national consciousness and political activity during the period of politicization of its national movement. Th e methodologi- cal principles. Based on the analysis of rich literature on the history of religion, the author of the article used the methods of historical analysis and synthesis, as well as the comparative method and the method of systemic analysis, to consider the interaction of Eastern Christian denomina- tions and determine their infl uence on the national movement in Ukraine. Conclusions. Th e author analyzed the cultural, social, and political traditions that infl uenced the formation of the Ukrainian national movement and the specifi cs of the impact of the clergy of the mentioned denominations on this process. Th e article draws attention to the fact that the infl uence on the development of the Ukrainian national movement depended on local conditions caused by the political, cultural, and social features of certain territories of Ukraine. An important factor in the success of nation-building processes was the support of the Ukrainian national project by the clergy of the dominant faiths. On the territory of Halychyna, the support of the Greek- Catholic clergy was of great importance for the crystallization of Ukrainian self-awareness among the population. In turn, in Dnipro Ukraine, the Orthodox Church remained a bastion of Slavophilism and Russian nationalism for a long time, and only at the beginning of the 20th century did autocephalous ideas, supported by a small group of the clergy, begin to appear in its midst. Although the Orthodox clergy only partially supported the Ukrainian cultural and later political movement, the very fact of the participation of some of its fi gures in Ukrainophilism strengthened the Ukrainian identity among the parishioners. Th e importance of both confessions for developing the Ukrainian national movement determines the particular importance of their dialogue in modern Ukraine based on partnership relations and ecumenism.

Relevance. The study characterizes the design of a mixture of gluten-free flours and fenugreek seeds (Trigonella foenum-graecum) to improve the properties of gluten-free biscuits and determine dough and finished product predictors. A distinctive feature of the mixture is the presence of raw ingredients with high nutritional and biological value. The data obtained can be used in the development of new product lines, new recipes for specialized flour confectionery.

Methods. To study the effect of corn flour, rice flour, flaxseed flour and fenugreek seeds on the quality characteristics of simple biscuits, standard test methods were used. The composition of the prescription components was selected taking into account the specialized focus of the product, the biological value of the ingredients, the high sensory characteristics of the finished product, and the imparting of functional properties.

Results. The optimal quantitative ratios of corn flour, flaxseed and rice flour (45:45:10) and the proportion of fenugreek seeds (7.5% by weight of flour) were experimentally determined. The quality indicators of the developed products are investigated. It has been established that the use of flour gluten-free mixture and fenugreek seeds affect a slight increase in dough moisture, acidity and wetness of finished products. Recommended standardized requirements for gluten-free biscuits from a mixture of corn, rice, flax flour and fenugreek seeds are proposed. As additional quality indicators, the content of gluten, dietary fiber and magnesium is highlighted. The developed simple biscuits for specialized purposes have a functional focus due to the high content of dietary fiber and magnesium, the share of which is more than 15% of the daily intake of these nutrients.
Chicken nuclear DNA in chicken egg whites
Authors: Zyrianova I. M.
Published: September 2023

Poultry eggs contain high-quality proteins, fats, vitamins and minerals, which makes them an indispensable product in human nutrition. Egg whites have exceptional foaming, emulsifying, gelling, and heat setting properties, making them popular for use in baked goods. The knowledge accumulated so far about egg whites has now settled on a stable opinion that there are no cells, and no DNA, in them. However, this study demonstrates the possibility of extracting chicken genomic DNA from the outer thin whites of chicken eggs. For DNA extraction, foremost, protein degradation of the samples by trypsin was used. The amount of isolated DNA ranged from 0.3880 ± 0.0348 to 0.6380 ± 0.0545 μg/ml of the white sample. A PCR test based on 18S ribosomal DNA showed that the DNA isolated from the outer thin white contained avian genomic DNA. Furthermore, cloning and sequencing of the bird-specific PCR fragment showed that this DNA belongs to chickens (Gallus gallus). In addition, staining with Hoechst 33342 showed the presence of cell nuclei in the samples. Therefore, this study demonstrates that chicken egg whites contain chicken genomic (nuclear) DNA and cell nuclei (i. e., and cells).

Relevance. Dependence on fishmeal hinders the development of the poultry industry. The aim of the study was to analyze the expression of key genes in the parent stock of Gallus gallus L. lines CM5 and CM9 of the meat cross «Smena 9» on the background of diets with the replacement of fish meal.

Methods. Experiments were carried out on CM5 and CM9 chickens: groups 1A and 1B received the main diet (MD), 2A and 2B — MD with the replacement of fish meal with soy products, 3A and 3B — MD with the replacement of fish meal with sunflower products, 4A and 4B — MD with the replacement of fishmeal with soybean and sunflower products at a ratio of 50:50. Gene expression analysis was performed using quantitative reverse transcription PCR.

Results. The most pronounced changes in the levels of expression of key genes against the background of the replacement of fishmeal with soybean and sunflower processed products concerned the maternal line Plymouth Rock CM9 compared to the paternal line Cornish CM5. Thus, the expression of SOD mRNA in groups 2B, 3B and 4B decreased by 14.3–100 times compared with control 1B (р ≤ 0.05). Whereas in the experiment on the CM5 line, the expression of the SOD gene in the experimental groups 2A and 3A decreased by no more than 3.5 times compared with the control 1A (р ≤ 0.05). In all experimental groups, zootechnical indicators of meat and egg productivity were noted at the level of control groups (р > 0.05).

El papel de la enseñanza religiosa ante el crecimiento de la intolerancia religiosa en Brasil
Authors: Castoldi Ariany de Souza Paula
Published: September 2023

En este artículo, el objetivo principal es analizar el papel de la enseñanza religiosa frente al crecimiento de la intolerancia religiosa. Siendo Brasil un país mayoritariamente cristiano y sabiendo que en el aula el profesor puede imponer puntos de vista personales, la problemática plantea la siguiente pregunta: ¿cómo evitar que esto resulte en una enseñanza religiosa proselitista? Como hipótesis, este artículo defiende la idea de que la solución radica en una mejor formación de los profesores de enseñanza religiosa, quienes deben basarse en las Ciencias de las Religiones para garantizar una enseñanza no confesional. Entre las justificaciones, se encuentra la necesidad de adecuar la Enseñanza Fundamental, poniéndola al servicio de una sociedad democrática, libre de prejuicios y que acepte la diversidad. Por lo tanto, es fundamental que la enseñanza religiosa se muestre libre de proselitismo e integre la lucha contra la intolerancia religiosa, especialmente en lo que respecta a las religiones de origen africano. En cuanto a los procedimientos metodológicos, se destacan las investigaciones de carácter bibliográfico y documental, a través de las cuales se buscó conocer los principales conceptos y la línea filosófica predominante que guían la educación brasileña, así como los instrumentos legales que ayudan a combatir la intolerancia religiosa en Brasil.

Published: September 2023

Gmelina arborea is a very important timber species as it provides wood for furniture, serves as carbon sink and creates micro-climate with decrease soil temperatures enabling smaller niches to be formed within the forest ecosystem. Also, the nutrients composition of forest soil determines its stand structure and composition, growth rate and dominance, including other silvicultural practices. The study assessed soil quality and height-diameter (H-D) models in the management of Gmelina arborea plantation in Nasarawa State University. Thirty (30) temporary sample plots of 0.01 ha size were randomly selected from the sampling frame with 30% sampling intensity. Thereafter, the total height and the Dbh of each tree within the selected plots was measured for height-diameter model assessment. Also, ten (10) soil samples were randomly collected from the thirty (30) selected plots for H-D modeling in order to assess the soil properties of the plantation. Soil samples obtained were analyzed in the Faculty of Agriculture Laboratory to obtain data and further subjected to statistical analysis. The results of height-diameter models revealed that model one (1) with Akaike Information Criterion (62.19), Bayesian Information Criterion (66.39) and Residual Standard Error (0.64) had the lowest model selection indices when compared with other four models applied. Therefore, model one (1) was selected as the best and grand model for Gmelina aborea plantation in the study area. Also, the result of soil quality showed a significant difference between the soil properties in the study area. The Least Significant Difference result also showed that...

The study conducted a retrospective analysis of the genesis, formation and development of a general secondary education institutions network in rural areas of Ukraine. Taking into account the broad socio - cultural and political contexts, stages of rural schools network formation related to the emergence of a network (stage 1), its functioning (stage 2), transformation and consolidation of the existing network (stage 3) were revealed, development of the existing network at the expense of active development low -complex schools and schools with low -content classes (stage 4), new enlargement of the school network (stage 5). It is determined that the emergence of a rural schools network is related to democratic trends both by the totalitarian state and by the local initiative from below - by provincial and county zemstvos. And in the stages of formation of a schools network, dynamic and cyclical fluctuations from the democratic principles of formation from below and taking into account the interests of the population in formal administration by a totalitarian state are traced. The dependence of the formation of a schools network and its quality on the state policy on the formation of the system rural population and territorial-administrative reforms is established. The tendency of increasing enlargement of the schools network and cultural and household services in rural areas has been identified, which in turn leads to inequality of access to the services of rural and urban population and accordingly causes the outflow of the population from the villages. The need for more flexible planning of the network, taking into account local features, the need for individualization of approaches to the formation of networks in different territorial communities and regions, which can be facilitated in recent years by domestic scientists network models of integration, cooperation of educational institutions and complex training of various age groups. In order to achieve the goals of sustainable development of the country, it is necessary to form an effective network of pre -school and extracurricular education institutions, general secondary education, creating conditions for the possibility of learning throughout life.

Follicular lymphoma (FL) is the most common type of indolent non-Hodgkin lymphoma. Despite treatment advances that have improved outcomes for patients with relapsed or refractory (R/R) FL, many patients still die from progressive disease or treatment-related toxicities.
In the phase Ib/II GO29365 study (NCT02257567), the safety and efficacy of polatuzumab vedotin plus bendamustine and rituximab (Pola-BR) versus BR alone, and polatuzumab vedotin plus bendamustine and obinutuzumab (Pola-BG) as a single-arm cohort were evaluated in patients with R/R FL. Following the phase Ib safety run-in, patients were randomized 1:1 to receive Pola-BR or BR alone in the phase II stage; a separate non-randomized Pola-BG cohort was examined in the phase Ib/II expansion stage. Primary endpoints included safety and tolerability (phase Ib) and positron emission tomography complete response (PET-CR) rate by independent review committee (phase II).
Overall, 112 patients were enrolled (phase Ib safety run-in: Pola-BR, n=6; phase II randomized cohort: Pola-BR, n=39; BR, n=41; phase Ib/II expansion cohort: Pola-BG, n=26). PET-CR rates were 66.7% (phase Ib safety run in, Pola-BR); 69.2% (phase II randomized, Pola-BR); 63.4% (phase II randomized, BR); and 65.4% (phase Ib/II expansion Pola-BG). There was a higher occurrence of cytopenias with Pola-BR and Pola-BG than with BR; serious adverse events were more frequent with Pola-BR (61.4%) and Pola-BG (46.2%) than with BR (29.3%). Overall, this analysis does not demonstrate a benefit of adding Pola to BR or BG regimens for patients with R/R FL.
Reflexivity and Meta-Emotions in the Interdisciplinary Project for a Better Understanding of Emotions
Authors: Mendonça Dina
Published: September 2023

The localized commentary focuses on the way in which meta-emotions appear in the last chapter, and how reflexivity more generally is addressed. It shows how meta-emotions require a detailed explanation, which should capture their role and place within the interdisciplinary theoretical proposal in the already dense book. Though the commentary is limited to this specific issue, it is important to acknowledge and admire the proposal for its unity based on an interdisciplinary foundation. It highlights why every theory of emotion seems to capture something important about the nature of emotions. Nevertheless, Mun’s book would have been greatly improved with the connection of her own proposal to previous work done on meta-emotion. Though it is understandable it did not take place in the book, this commentary aims to point out possible future research directions which will connect the unifying hypothesis with reflexivity of emotions.

Waste heat is heat produced by a machine or other process that uses energy as a byproduct of doing work according to the laws of thermodynamics. The recovery of this waste energy helps to provide valuable energy sources, increase the efficiency of machines and reduce overall energy consumption. This research examines waste heat recovery from an electric generator for hot water supply for domestic uses in homes and offices. A fabricated heat recovery system consisting of an insulated steel water tank was attached to the exhaust pipe of a 3.5KVA, Elepaq generator by a copper pipe. The copper pipe carries water from the tank, winds around the generator's exhaust pipe, and then carries water back into the tank. The result from the study shows that 107J of heat is gained by 9.48kg of water per second of the experiment. The water temperature in the tank rises from 26˚C to 62.3˚C within 225 minutes. As shown by this study, recovering waste heat from the household electric generator can be achieved for domestic work such as water boiling for bathing, tea making, washing, cleaning, and baking.

Published: September 2023

Представлен анализ российских и зарубежных нормативных документов, регламентирующих проектирование конструктивных систем в особых расчетных ситуациях. Показано, что ряд задач, связанных с проблемой безопасности конструктивных систем при особых воздействиях, остаются недостаточно исследованными, а достоверность некоторых важных положений не подкреплена экспериментальными исследованиями живучести конструктивных систем зданий и сооружений. В порядке обсуждения рассмотрены предложения, относящиеся к проблеме оценки рисков конструктивных систем в особых расчетных ситуациях на вероятностной основе и установлению допустимой меры надежности, базирующейся на единой концепции и явно выраженных в целевых значениях вероятностей отказа индексов надежности, которые используются для калибровки частных коэффициентов в моделях сопротивлений конструктивных систем. Отмечается, что для принятия обоснованных решений следует выполнить объективное сравнение расчетных положений действующих и предлагаемых нормативных документов, опираясь на результаты оценки величин рисков как, например, показано в примерах данной статьи.
Остаточная энергия деформации при прогрессирующем предельном состоянии конструкции
Authors: СТУПИШИН Леонид Юлианович , НИКИТИН Константин Евгеньевич , МОШКЕВИЧ Мария Леонидовна
Published: September 2023

Рассмотрена методика прогрессирующего предельного состояния конструкции, реализуемая в форме метода сил. Известные постановки задач расчета строительных конструкций основываются на принципе минимума полной энергии их деформации - подходе Лагранжа, согласно которому получаемый проект соответствует заранее заданной нагрузке. Однако, используя эту постановку, получить информацию о максимальной несущей способности конструкции, о ее остаточной несущей способности в детерминированном виде не удавалось. Предлагается использовать критерий критических уровней энергии деформации. Уравнения состояния конструкции на таких уровнях получены из вариационного принципа минимума потенциальной энергии деформации на критическом уровне энергии. Критерием нарушения предельного состояния конструкции служит изменение состояния ее самонапряжения. Показано, что в предлагаемой постановке условие предельного состояния конструкции определяется экстремальными значениями обобщенных параметров проектирования на всей области их допустимых значений, включая границу. Приведенный пример расчета статически неопределимой фермы наглядно демонстрирует изменение энергии деформации конструкции и ее самонапряжения.

В связи с вхождением в состав Российской Федерации новых территорий возникла потребность в разработке для них норм по строительной климатологии, необходимых для проектирования и строительства зданий и сооружений в городах Донецкой и Луганской Народных Республик, а также Запорожской и Херсонской областей. С этой целью проведена работа по подготовке изменения № 2 к своду правил 131.13330.2020 "СНиП 23-01-99* Строительная климатология". На основе мониторинга действующих метеостанций на рассматриваемых территориях установлено, что значительная часть климатических наблюдений имеет пропуски протяженностью от 10 до 25 лет. Поэтому для включения в свод правил было выбрано девять пунктов с метеостанциями на новых территориях. В результате проведенной работы стало возможным рассчитать климатические параметры для холодного и теплого периодов года, среднюю месячную и годовую температуры воздуха, максимальную суточную амплитуду температуры воздуха в июле, среднее месячное и годовое парциальное давление водяного пара, среднюю и максимальную суточную амплитуды температуры наружного воздуха, а также провести климатическое районирование для этих регионов.
