Some Mechanical Equilibrium Problems. A Geometrical Point of View
Authors: Constantinescu Ștefania
Published: December 2023

In this paper we give a geometrical solution for a mechanical equilibrium problem, namely for a bar that is hung by 2 threads from a fixed point. Despite the fact that most of the engineering modelling problems are solved using Mathematical Analysis, we will reduce the solution of our problem to determining the coordinates of a certain point in the Cartesian coordinate system. More, we will find the value of the forces appearing in the threads. Some generalizations are provided. The mechanical notions are minimal and they will be mentioned at first and some very simple geometric results, such as bisectrix theorem, law of cosines, the congruence of the angles will be used all along the paper. The forces that are not taken into account in the problem are considered negligible.
Innovative Design Process for Intelligent Buildings
Authors: Fratu Mariana
Published: December 2023

An intelligent building needs to be designed to meet the needs of initial occupants and be flexible to meet the needs of future occupants. Creating an intelligent building does require an investment in advanced technology, processes, and solutions. An ingenuous investment is required to realize a significant return later on. It is unrealistic to expect to make a project intelligent unless there is early acquisition in on investment. Over, these decisions need to happen prior to the start of design work. One of the challenges is to educate owners on the benefits of an intelligent building design. This makes the education of both owners and architects about the benefits of intelligent solutions significant for success.

Authors:   Institute of Development Studies, Ebata Ayako , Bellwood-Howard Imogen , Battersby Jane ,   University of Cape Town
Published: December 2023

Food systems employ billions of people across the world, many of whom are socially and economically marginalised. The livelihoods within the food systems these people rely on tend to be precarious and low in economic return, exacerbating social and economic inequality while preventing food systems from improving their ecological sustainability. In this paper, we review the different ways in which equitable livelihoods within food systems are conceptualised across academic communities, and what interventions are suggested to make food systems livelihoods more equitable. We analyse the tensions and complementarity between these different approaches and suggest an inter- and trans-disciplinary methodology.
Dynamiques des paysages forestiers au Mozambique : étude de l’écologie du Miombo pour contribuer aux stratégies de restauration des terres dégradées
Authors: MONTFORT Frédérique
Published: December 2023

La dégradation des terres constitue un enjeu écologique, sociologique et économique majeur à l'échelle mondiale. Le Mozambique, qui dispose encore d’une importante ressource forestière dominée par les forêts de Miombo, est particulièrement touché par ce phénomène, avec près d’un quart de ses terres qui seraient déjà dégradées. Ce pays s’est fixé l’objectif ambitieux de restaurer 1 million d’hectares de terres dégradées d’ici 2030. Cependant, il existe très peu de données quantitatives et spatialisées sur l'état des terres et sur la capacité de résilience du Miombo. L'objectif de cette thèse est d'analyser les dynamiques, les caractéristiques et les déterminants de l’évolution des paysages forestiers afin d’alimenter les stratégies de restauration des terres dégradées au Mozambique. Cette étude s’est particulièrement intéressée à comprendre les facteurs de dégradation des terres à l'échelle nationale, à évaluer la résilience de l’écosystème du Miombo dans les systèmes d’agriculture sur brûlis dans la région centrale du pays (Zambézie), et enfin à proposer une approche pour identifier les zones et stratégies potentielles de restauration des paysages forestiers. Dans un premier temps, les analyses de séries temporelles satellitaires (indices de végétation et variables climatiques) ont permis de documenter l’état des terres à l’échelle nationale et de quantifier les facteurs de dégradation et régénération des terres. Des inventaires floristiques, pédologiques et des enquêtes de terrain ont été menés en périphérie du Parc national de Gilé, afin d’analyser les dynamiques de régénération forestière après défriche-brûlis et l’impact des cycles répétés de culture-jachère. Ces connaissances issues des études par télédétection et d’inventaires de terrain ont été combinées dans une approche innovante permettant d’identifier les zones prioritaires de restauration et les options de gestion (restauration passive ou active), afin d’améliorer des fonctions du paysage (accumulation de carbone, connectivité des habitats) et de renforcer la biodiversité. Cette approche s’appuie sur une analyse multicritère et le développement d’indicateurs spatialisés environnementaux et sur les trajectoires des agrosystèmes. Cette thèse contribue à une meilleure compréhension des processus et des facteurs de dégradation des terres ainsi que de l’écologie du Miombo. Elle propose une approche innovante pour contribuer à l'élaboration de projets ou programmes de restauration des paysages forestiers au Mozambique.

Philosophical bases of divergent thinking
Authors: Kochukova Olga N.
Published: December 2023

Importance. At the current stage of socio-economic development of the country, society’s need for specialists with divergent thinking, which allows thinking innovatively, solving non-standard tasks in conditions of uncertainty and rapid change of situation in different ways is actualized. However, there is a problem associated with the lack of a common theoretical basis and methodological approaches to the study the divergent thinking. It is assumed that it is possible to understand the nature of divergent thinking through philosophical comprehension of its generic concept “thinking”. The aim of the research is to scientifically substantiate the category of "divergent thinking" from the philosophical point of view.
Materials and Methods. Achievement of the set goals was carried out on the basis of retrospective analysis of philosophical, literature and scientific publications on the topic of research.
Results and Discussion. The main essential characteristics of thinking and thought operations underlying it in general and divergent thinking in particular were determined. The conceptual character of thinking based on judgments, inferences and concepts is defined. It was found out that the regularities of thought processes are conditioned by such thought operations as synthesis, analysis, generalization, classification, abstraction and others. At the same time, the heuristic nature of cognitive process is provided by means of intuitive insight. It is concluded that the foundation of the phenomenon under study is the dialectical nature of thinking aimed at research and resolution of contradictions.
Conclusion. The field of application of the obtained results is the definition of the essence of divergent thinking of university students, research of the problem of its formation and further development.

Authors: Zverkov Evgeny A. , Savitskiy Nikolay M.
Published: December 2023

Importance. The emergence and development of the system of professional police education in Soviet Russia in the first years after the October Revolution is considered. The relevance of the research lies in the possibility of using some approaches to the organization of the educational process for modern educational programs.
Materials and Methods. The system analysis’ methods, the principles of historicism and scientific objectivity, the use by the authors of the entire array of identified historical sources directly related to the object of research are used. Archival materials are stored in the State Archive of the Russian Federation, the State Archive of the Tambov Region, the State Archive of Socio-Political History of the Tambov Region, the State Archive of the Voronezh Region are used.
Results and Discussions. The militia bodies of the early 1920s, first of all, had to contribute to the strengthening of the Soviet apparatus. In this regard, the personnel policy in the militia was also being built. However, workers and peasants did not have proper legal and general education training, which required significant efforts by the state to develop a network of specialized educational organizations (schools, courses) for political and practical training of policemen. According to the authors, significant positive experience in this area has been accumulated in the Central Chernozem region – especially in the Tambov province.
Conclusion. Conclusions are formulated about the significant potential of departmental education in the first half of the 1920s, the full implementation of which was hampered by the low capacity of schools and a significant bias towards militarization of training.
Endothelial dysfunction as a source of short-term and long-term pathological effects in SARS-CoV-2 viral lesions
Authors: Reshetnikova Elizaveta V. , Polyakov Dmitry V.
Published: December 2023

Despite the relatively low mortality rate, SARS-CoV-2 infection is characterized by the presence of a number of complications that significantly affect the life of recovered patients. Thorough analysis of coronavirus infection mechanisms shows that endothelial dysfunction plays a key role in the development of the disease and long-term symptoms. Endothelial damage is associated with the occurrence of a number of long-term symptoms affecting various organ systems in infected patients. Also the existing polymorbidity (hypertension, obesity, diabetes mellitus, oncological and chronic respiratory diseases) in a patient with a new coronavirus infection are risk factors for a severe course of the disease development. The mutual burden of various pathologies in the potentiation of the development of new abnormalities makes it relevant to further study of endothelial dysfunction in SARS-CoV-2. The purpose of this research is to analyze current scientific data within the framework of understanding the causes of short-term and long-term pathologies associated with vascular endothelial dysfunction in SARS-CoV-2 viral lesion. Materials and methods of research: we analyze international modern scientific publications on endothelial damage in COVID-19 and its complications. Conclusion: a scientific research based on modern literature data allows to propose promising treatment strategies that can save patients from long-term complications.

Published: December 2023

The research examines the concept of soft skills, which include qualities, attitudes, problem-solving skills, leadership and interpersonal skills, communication skills and emotional intelligence. We consider social intelligence as the basis for the formation of soft skills. These skills are important for effective interaction and decision-making in the business process, communication in teams and teamwork. It also discusses such an important concept for the justification and development of soft skills as “social intelligence”, which includes knowledge and understanding of the main ways of communication, leadership, decision-making and teamwork, as well as the ability to evaluate the interaction between people and the ability to use these factors to improve work results. The development of social intelligence requires not only practice, experience and constant self-improvement, but also a special approach based on the basic principles of adult pedagogy.
Acceptance of service and care robots from the nursing perspective
Authors: Solbrig Patricia , Honekamp Wilfried
Published: December 2023

To counteract the nursing shortage in Germany, approaches other than more nursing and junior staff are needed. One possibility is the use of service and care robots. These can be used, among other things, to assist with physically difficult work, to reduce walking distances, to carry out logistical tasks and to care for patients. The use of these robots requires the willingness of both the patients and the nursing staff. This contribution addresses the extent to which nursing and service robots are accepted and desired from the point of view of nursing staff. Therefore, 34 nursing staff members of a rehabilitation clinic provided information about their current willingness to accept five presented service and nursing robots. The results showed that the service robots, which take over walking and logistical tasks, find almost unrestricted acceptance. However, in the case of social care robots, with direct, immediate contact with and to the patient, there are definitely moral and ethical concerns. Nevertheless, the use of these robots is also advocated by most nursing staff, as the potential for use is very high. Education, training and practical measures increase acceptance and can also ideally dispel ethical and moral concerns. For the future, a broader use of nursing and service robots could contribute to reducing physical strain and routine tasks and thus make the nursing profession as a whole more attractive.

Published: December 2023

Este artigo, problematiza os impactos do ensino remoto no estado emocional de professoras alfabetizadoras iniciantes da carreira docente, durante o distanciamento social imposto para conter a disseminação da Covid-19. Trata-se de uma pesquisa qualitativa, realizada com quatro professoras da rede pública municipal do Rio Grande do Sul. Os dados são oriundos das narrativas produzidas nos encontros de formação, que indiciam complexidades com relação às adaptações iniciais da nova modalidade de ensino, frente as demandas do trabalho remoto. Observou-se que a lógica capitalista de uma superprodução constante, invade e compromete o tempo relacionado ao descanso e lazer dessas profissionais, extrapolando sua carga horária habitual. As docentes sentem-se sobrecarregadas com tantas exigências que transgridem suas responsabilidades profissionais, levando-as à exaustão ou doenças psíquicas.

HISTORY OF HYDROCARBON ACCUMULATIONS IN BEDS OF THE MALYSHEVKA FORMATION ON THE TERRITORY OF KARA-YAMAL REGION
Authors:   A.A.Trofimuk Institute of Petroleum Geology and Geophysics SB RAS, Novosibirsk, Russia, Kazanenkov V. A.
Published: December 2023

The paper describes the characteristics of source beds, considers the structure of fluid seals and formation stages of anticline structures within Kara-Yamal region, bounded from the south by the Messoyakha inclined ridge. Investigations were carried out on the basis of comprehensive generalization of published geological and geochemical materials. It is shown that all formations of the Lower and Middle Jurassic containing aquagene, terragene and mixed types of kerogen in various proportions, possessed oil and gas generating properties. The significant implementation of generation potential due to the high OM catagenetic transformation in rocks of the Middle and especially Lower Jurassic caused the formation of mainly condensate gas accumulations in reservoirs of the Malyshevka Formation. The stages of formation of clay fluid seal in the process of lithogenesis are considered, it was determined by the feature of subsequent transgressive-regressive sediment filling relative to the deep–sea basin in the Late Berriasian – Early Aptian. The history of the anticline structure formation in the roof of the Jurassic structural stage is analyzed separately. According to the results of this analysis, it was found that hydrocarbon accumulations matured within the structures whose main stages of development coincided with the Jurassic period and Early Cretaceous epoch. The beginning time of filling traps with hydrocarbons was defined on the basis of information comparison about the time of compaction of clay strata of the Late Bathonian – Kellovian to the state of fluid seal and time of implementation of the HC main generation phases by oil –and- gas generating rocks. It is concluded that the lithification asynchrony of the fluid seal clay deposits predetermined the time diversity of the HC accumulation generation in the Malyshevka Formation in geological past.

Perfis de relevo e índices geomorfométricos na análise evolutiva do escarpamento da Serra dos Órgãos (RJ)
Authors: Paixão Rodrigo Wagner , Silva Telma Mendes da , Kuchler Patrick Calvano
Published: December 2023

O presente artigo tem por objetivo investigar a evolução do escarpamento da Serra dos Órgãos nos últimos milhares de anos através de análises morfológicas e geomorfométricas, realizadas por meio de perfis topográficos, mapeamento de níveis de base locais (knickpoints), perfis longitudinais de drenagem e cálculos do fator Chi (χ). Estas análises buscaram avaliar o grau de “instabilidade” dos canais de drenagem e da direção de migração dos divisores de drenagem. Ao todo foram identificados 130 knickpoints, sendo boa parte deles, 67 ao todo, associados à unidade Suítes Graníticas, tanto para a vertente escaparda quanto para o Planalto Reverso. Além disso, estes knickpoints são encontrados nas porções mais elevadas da área de estudo, podendo ser identificados acima dos 1.000 m de altitude. A distribuição altimétrica das unidades litológicas indica controle dos granitos na manutenção das porções mais elevadas, podendo atingir 2.200 m de altitude, assim como nos perfis de relevo elaborados indicam controle litológico dos granitos na manutenção da morfologia escarpada e do divisor hidrográfico da Serra dos Órgãos. Os perfis de relevo e longitudinais aos canais fluviais realizados apontam que bacias que drenam para o planalto interiorano possuem maior número de níveis de base locais, 101 ao todo, e foram interpretados como encontrando-se em estágio de maior “desequilíbrio” erosivo do que as bacias da frente escarpada, que apresentou apenas 29 knickpoints. Eventos tectônicos recentes podem ser sugeridos a partir dos perfis elaborados, influenciando diretamente nas características geomorfológicas e geomorfométricas da área de estudo. Os perfis de canais situados na vertente oceânica da Serra dos Órgãos sugerem canais fluviais em graus avançados de processos erosivos, dados pela conformação côncava dos perfis típicos de rios “equilibrados”; no entanto, pelos valores do fator Chi (χ) estas drenagens permanecem apresentando maior potencial erosivo das cabeceiras frente às bacias voltadas para o planalto reverso indicando, portanto, mecanismos de rearranjos de drenagem e de migração do divisor.

Published: December 2023

This work consists of the application of a new geomorphological mapping methodology with a focus on anthropogenic landforms. The study area is the central sector of the metropolitan region of Joao Pessoa, where densely urbanized areas and rural areas are found, but with high human intervention. The geomorphological mapping methodology proposed in this work was developed from Brazilian, English, and Italian experiences and included extensive field trips. The result was quite satisfactory where the final map represents from the present geological foundation (morphostructure) to the current anthropogenic landforms. A broad and integrated legend representing all mapped taxa was also proposed. The geomorphological map produced, in addition to being a synthesis of the geomorphological research carried out, is an important tool for urban and environmental planning.
Towards an understanding of the aetiology, genomic landscape and management of Moebius syndrome
Authors: Lyulcheva-Bennett Ekaterina , Blumenow Wendy , O’Connor Adelene , Kelly Maria , Bennett Daimark , Fattah Adel
Published: December 2023

Moebius Syndrome (MBS) is a rare neurodevelopmental disorder characterised by facial paralysis and ocular motility defects. Its origins trace back to the 19th century, with its clinical delineation attributed to German neurologist Paul Möbius. The syndrome presents with a spectrum of variable systemic clinical features, necessitating a multidisciplinary approach to diagnosis and management. The prevalence of MBS has been estimated to range between 1 in 50,000 to 1 in 500,000 individuals, with a universal distribution across ethnicities and genders. The aetiology of MBS is poorly understood but is likely multifactorial, with developmental, genetic, and environmental factors playing roles. Recent research has identified potential genetic contributors, REV3L and PLXND1, but further work is needed to elucidate the genetic landscape of this rare neurodevelopmental disorder. Here we describe the current understanding of the clinical features, aetiology, genetic landscape, and management of MBS, emphasising the importance of early diagnosis and a holistic approach to patient care. We also propose a set of criteria aimed at standardising MBS reporting to enhance information sharing and bolster MBS research initiatives. Collaborative research efforts in the future hold the potential to offer transformative insights and improved outcomes for affected individuals and their families.
Approximate solution to the Two-Body problem perturbed by periodic acceleration
Authors: Suslov Kirill Sergeevich
Published: December 2023

In this paper, author proposes an approach to approximate orbital dynamics in the model of a perturbed Two--Body problem, which leads to a system of equations with a closed-form solution. The approach is based on representing the components of the disturbing acceleration by Fourier series in eccentric longitude with constant coefficients, writing out the equations of the perturbed two-body problem in terms of modified equinoctial elements, and averaging the right-hand sides of the equations of motion over the mean longitude on one orbit. It is discovered that the influence of disturbing acceleration on the resulting averaged equations can be parameterized by a finite set of scalar parameters, which are the coefficients of the Fourier series. Solutions of the averaged equations are found in a closed form in case of orbits with low eccentricity.

Determining the optimal application rate of chicken manure for agricultural land through Phosphorus sorption-desorption analyses in Andisols of Wonokitri, East Java, Indonesia
Authors: Noor Muhammad Yussaq , Hartono Arief , Nugroho Budi
Published: December 2023

Phosphorus (P) is a macro-essential element extensively used in agricultural production. Andisols, commonly found in Indonesia, serve as agricultural areas with high, excessive, and continuous organic matter input. However, the propensity of the soil for P leaching poses a potential risk of water pollution and eutrophication in the watershed area. This study aimed to evaluate the impact of the application rate of organic matter, specifically chicken manure, often employed in agricultural activities related to Andisols. The experiment involved observing P sorption, P desorption, P sorption kinetics, and P uptake by wheat (Triticum aestivum) in soil incubated with chicken manure added at various rates of 0, 10, 20, 30, and 40 t ha-1. The incubation stages were conducted for 14 days at room temperature (27°C) and soil moisture was maintained within field capacity. The data collected were analyzed using Langmuir isotherm for P sorption and desorption, and first-order kinetics for P sorption kinetics. The results showed that the chicken manure addition at 10-40 t ha-1 significantly reduced P bonding energy in Andisols, but failed to decrease the sorption maxima value due to accumulated P from previous applications performed. The application of 20 t ha-1 (CM20) of chicken manure was found to be the optimal rate, displaying high P uptake and reduced bonding energy, while rates above 20 t ha-1 showed no significant difference in P uptake and bonding energy levels. Therefore, CM20 was recommended to increase P availability and prevent P movement into water bodies, promoting sustainable agricultural practices.

Los biorreactores son una de las soluciones que propone la ingeniería de tejidos para las principales enfermedades en México. Las matemáticas pueden determinar parámetros biocinéticos, que crean mecanismos para optimizar las condiciones de operación. Por lo tanto, la presente investigación tiene como objetivo diseñar un modelo matemático dinámico que describa el comportamiento de las células hepáticas, la producción del sustrato y proteínas en un biorreactor. Como resultado, se obtuvo que el modelo propuesto puede predecir a través del tiempo el comportamiento de las variables. Algunos de los parámetros biocinéticos encontrados son YXS = 2.94 g/g, YPS = 5.46 g/g, y μmáx = 1.84 1/h. A su vez, se empleó un análisis paramétrico de sensibilidad para encontrar los parámetros que tuviesen el mayor efecto en las concentraciones de biomasa y producto. Los parámetros son YXS, α y β para la concentración de biomasa y μmáx, YXS, KPS para la concentración de producto. Como parte del estudio, varias simulaciones se emplearon para determinar el comportamiento en distintas concentraciones iniciales de sustrato. Los resultados arrojaron que entre más grande sea la concentración inicial de sustrato, menor será el rendimiento dentro de los primeros ocho días. Después de ese tiempo, los rendimientos son similares para todas las concentraciones iniciales de sustrato.

Trends towards the development of distributed generation involve a number of problems related to maintaining the quality of electric energy in medium and, especially, low-voltage networks. The article examines the impact of monitoring the quality of electricity of low voltage classes on the reliability of the electrical network. MSZ EN 50160 and Hungarian Energy and Utilities Regulatory Office (MEKH) standards are considered. In accordance with MSZ EN 50160, the main indicators of the quality of electric energy are considered, such as: frequency, voltage fluctuations, rapid voltage changes, Flicker dose, voltage dips, short-term voltage interruptions, long voltage interruptions, temporary overvoltages of industrial frequency, transient overvoltages between current-carrying conductors and voltage ground , harmonic voltage fluctuations, interharmonic voltage fluctuations. SAIFI and SAIDI are calculated according to the Hungarian Energy and Utilities Regulatory Office. The devices for monitoring the quality of electricity of low-voltage networks are analyzed. The factors affecting the choice of the place of installation of monitoring devices are considered. It is presented how power quality monitoring systems can reduce the number of malfunctions in the 0.4 kV network, and the influence of monitoring systems on the quality of electric power in 6-35 kV networks is considered.

Analysis of the ageing characteristics of transformer oils in 330 kV autotransformers during long-term operation
Authors: Ponomarenko Serhii
Published: December 2023

The analysis of dependences of transformer oil indicators in 330 kV autotransformer tanks on the duration of operation is performed. The description of the dispersion analysis model for checking the dependences for deviations from linearity is given. It is shown that it is possible to estimate the presence of nonlinearity in the dependences of oil indicators by comparing the value of the mean square of the deviation from linearity with the value of the residual mean square, which are determined within the dispersion decomposition. On the example of such an indicator as the organic acids content in the oil, using the results of operational tests on 48 330 kV autotransformers from three regions of Ukraine, the influence of mistakes and gross errors in the measurement results on the nature of the dependencies of indicators is analysed. The most characteristic types of distortions are highlighted. It was established that in the vast majority of cases the causes of distortions of the dependences of oil indicators on the duration of operation were the intervention of operational personnel to inhibit the aging processes of oils (replacement of silica gel, addition of antioxidant additives, oil drying, topping up or replacing oils). This indicates a high level of organization of operational control of the condition of transformer oils in the power systems of Ukraine. To identify distorted and stationary dependencies, it is proposed to use a model of regression analysis of oil indicators for the duration of operation. To reduce the heterogeneity of the results of oil condition tests, which is caused by differences in the design of autotransformers and their operating modes, the criterion of the maximum correlation ratio was used. According to the results of the analysis for deviations from linearity, it was found that the drift rate of the values of oil indicators in the tanks of 330 kV autotransformers is not constant during the observed operation intervals (more than 30 years). On the analysed dependences of the indicators on the duration of operation, two characteristic areas were identified that correspond to certain stages of the oxidation process - the induction period (a period of time during which the values of the indicators practically do not change) and the period of self-acceleration (a period of time during which an intensive change in the values of oil indicators is observed). At the same time, the duration of the induction period and the intensity of the change in the values of the indicators differ significantly even for one indicator and depend on the operating modes of the transformer and operating conditions.
CIRCULAR ECONOMY IN UKRAINE: ENVIRONMENTAL, SOCIAL AND CORPORATE GOVERNANCE (ESG) AS A TOOL FOR THE SUSTAINABILITY OF SOCIALLY RESPONSIBLE BUSINESS IN THE CONDITIONS OF OVERCOMING THE COVID-19 PANDEMIC

The article deals with current issues of the essence and significance of ESG as a tool of the circular economy to strengthen the sustainability of socially responsible business in the context of overcoming the COVID-19 pandemic. Particular attention was paid to the report based on ESG criteria to improve the implementation of management decisions. It was emphasized that in Ukraine the ESG strategy at the enterprise level is only developing. It was noted that the intention to implement ESG practices promoted by the UN is not the prerogative of exclusively large companies, but rather organic business development, since traditional financial accounting includes only internal resources and flows and economic (and some social and environmental) consequences of activities. It was also noted that in a circular economy, those companies that cannot respond to the necessary and expected changes go out of business. The traditional orientation of reporting on the disclosure of financial indicators is a thing of the past. Today, only socially responsible companies that focus on such approaches to attract investment can succeed: human rights and inclusion, combating climate change, ensuring sustainability. It wasargued that the spread of ESG practices in the long and medium term may result in improved transparency and accountability of companies that combine high-quality traditional corporate governance with ESG factors, increasing their own investment attractiveness and creating reputational advantages for Ukraine and the business environment as a whole.
