The features of the structure of loess soils, widespread on the territory of southern Kazakhstan, are considered, which must be taken into account when preparing foundations and laying foundations in this region. The assessment of the possibility of using promising foundations from piles in rolled wells in local conditions based on the algorithm of their implementation in other regions is given. The experience of the device of these structures in Shymkent and the factors constraining their widespread implementation are given. In the south of Kazakhstan, in particular, in Shymkent, the problem of building reliable foundations is very acute. This is due to complex geological conditions, namely, the spread of loess subsidence soils. Loess rocks are found on all continents, but they are most widely distributed in Europe, Asia and America. According to experts, with an average loess capacity of 10 m, the total area occupied by loess rocks on the globe is 19 million km2 [1]. Loess soils, from the point of view of builders, have an insidious property – to change their condition when they are soaked. Therefore, a review of the origin of loess bases can clarify the essence of the physical phenomena occurring in its thickness during the construction and operation of buildings and structures

The control problem of nonlinear systems with feedback is one of the most important problems in the theory of control. In particular, it requires modeling of complex control laws at the design stage of the controller with feedback that meets the strict requirements of modern technologies. The lack of a universal approach to the control law, due to the problems of stability, tracking and reduction of deviations in feedback control, requires different methods in computer modeling. The article discusses the computer modeling of robust control problems and stabilization of inherently nonlinear systems with state or output feedback. With the help of the Matlab GUI software package, the sample examples under consideration were performed and the results were obtained

The possibility of intensifying heat exchange by using wavy pipes and a membrane between them is considered. It is known that heat exchange in curved pipes and channels of the coil type proceeds more intensively than in straight ones. Increasing the intensity of heat exchange and the use of double-light screens will reduce the dimensions of the boiler unit, which will improve its technical characteristics. For this purpose, experimental studies of heat transfer and resistance in bundles of wavy pipes have been carried out in two flow directions: in the plane of bending of pipes and in the plane perpendicular to the bending of pipes. So, for the flow in the direction of bending pipes, heat transfer and resistance are 9% higher than in bundles of straight pipes. And for a flow perpendicular to the bending plane of wavy pipes, the heat exchange is 13%, and the resistance is 20% higher than in bundles of straight pipes. To further increase heat transfer, it is proposed to use finning by installing membranes between wavy pipes.

The issues of transferring the production of parts manufactured by cutting at the qaz Carbon LLP plant to casting in gypsum molds are considered. A methodology for designing the technological process of casting plaster molds using computer modeling is proposed. This method allows you to reduce material and financial costs, as well as reduce the time of mastering the production of parts by sand casting. One of the methods of casting is the production of castings, which provides a sharp increase in labor productivity. Using the Flow – 3D program, it is possible to significantly simplify the casting process, and forms are created taking into account the progress of the process of transition of the material from a liquid state to a solid state.

Optimization of the technological process based on the results of modeling the casting process by preparing the casting «bearing shield», reducing the amount of nutrients of the casting system, increasing the output coefficient of suitable casting, a 3D model core model is developed for the development of control programs for the production of equipment on CNC machines
On the Limits of Applicability of the Theory of String Vibrations in Assessing the Configuration of Wires of a Power Transmission Line in the Process of One-half-wave «Dance»

When studying the «dance», some authors assume that the configuration (shape) of the wire during a onehalf-wave dance corresponds to a sinusoid and the sinusoidal law is used as a coordinate function. With such fluctuations, all sections of the wire within the half-waves have the same direction of movement, simultaneously pass the neutral position and reach the extreme upper and lower positions. However, observations of the oscillatory processes of wires on the anchor spans of a power transmission line showed that at low mechanical stresses of the wire, the nature of the oscillation with one half-wave differs significantly from the above. The difference lies in the fact that additional vibration nodes appear within the span. Between the nodes, the wires move in antiphase, resembling three-half-wave oscillations, only with different half-wave lengths (edge effects). The coordinates of the moving nodes, as observations show, depend on the initial mechanical stress of the wire. In this regard, the question arises about the limits of applicability of the theory of string vibrations in describing the configuration of wires in the process of a one-half-wave dance. The results of experimental data on the identification of wire configurations for single-half-wave oscillations are presented. The calculation formula for the critical voltage of the wire, at which edge effects are observed, is obtained. The relevant conclusions are presented at the end.

Methods for improving the system quality of VLC systems design and operation are considered. VLC technologies represent a system that consists of functions and software The main function of the VLC system is data transmission based on LED technologies. According to ISO/IEC 17025-2000, ISO 5725-2002-the main importance is given to metrological support. VLC systems are particularly critical to the stability of operating modes, they are demanding to control modes and operating conditions, to choose the technical parameters of the component base during design. Robustness can be considered an integral indicator of the overall quality of the VLC system. Taking this into account, as a robust paradigm, we study its functional part, in the scope of structural modeling, using the example of an optoelectronic channel for VLC information transmission, including some technical solutions, and the quality of control and measuring processes as a metrological component of robust system support. As a quantitative assessment of functional robustness, it is proposed to use control risks and the correlation function of the connection between «input» and «output», which evaluates the quality of the data transmission channel. Mathematical and simulation models, as well as application software, were developed to assess and predict control risks.

The paper considers the effect of vibration exposure on changes in the structure of 30KhGSNMA steel after steel treatment by vibration during primary crystallization. Studies have shown that after vibration exposure under certain modes, the contamination index decreases, the grain score decreases, the structure becomes more homogeneous. The second part of the work is devoted to the study of the possibility of using normalization as a replacement for the improvement of 30KhGSNM steel subjected to vibration during primary crystallization. Melt samples of 30KhGSNM steel were subjected to vibration and then heat treatment, which consisted of normalization under different modes. At the end of the heat treatment, the hardness, tensile strength, and impact strength were evaluated. The microstructure of the samples was also studied using the Thixomet Pro software. The analysis showed that, depending on the cooling medium, the dispersion of perlite changes during normalization, which affects the hardness. Based on the studies carried out, it was concluded that for steel subjected to vibration during the primary solidification process, it is possible to use normalization with air-water cooling instead of improvement. The properties of the prototypes are comparable to those after improvement

Developing novel cancer therapies that exploit programmed cell death pathways holds promise for advancing cancer treatment. According to a recently published study in Science, copper death (cuproptosis) occurs when intracellular copper is overloaded, triggering aggregation of lipidated mitochondrial proteins and Fe–S cluster proteins. This intriguing phenomenon is triggered by the instability of copper ions. Understanding the molecular mechanisms behind cuproptosis and its associated genes, as identified by Tsvetkov, including ferredoxin 1, lipoic acid synthase, lipoyltransferase 1, dihydrolipid amide dehydrogenase, dihydrolipoamide transacetylase, pyruvate dehydrogenase α1, pyruvate dehydrogenase β, metallothionein, glutaminase, and cyclin-dependent kinase inhibitor 2A, may open new avenues for cancer therapy. Here, we provide a new understanding of the role of copper death and related genes in cancer.
Ogun in the Black Atlantic: Family History and Cross-Cultural Religious Exchange in Bahia, c. 1813–1970
Authors: Earl-Castillo Lisa Louise
Published: September 2023

Afro-Brazilian religions play a vital role in the history of northeastern Brazil, home to an enormous Black population. An especially well-known case is Candomblé, which arose in the state of Bahia, where a number of large temples dating back to the time of the slave trade have long attracted scholarly attention. Less well-known, however, is the parallel existence of shrines belonging to individual families. One, dedicated to Ogun, in the city of Salvador, recently gained government recognition as a site of memory. According to oral tradition, it was created by a freed African couple on the farm where they lived and worked. Drawing on oral traditions, ethnographic data, and archival sources, this article reconstructs the family’s history over the course of nearly two centuries, tracing the presence of cross-cultural exchanges over time, initially from Dahomean and Hausa religion and more recently from Yoruba and Catholic cosmologies.
“Neighborhood Library Modernization”: Public Library Development and Racial Inequality in Milwaukee during the 1960s
Authors: Brenner Maddi
Published: September 2023

By the early 1960s, the Milwaukee Public Library (MPL), Richard Krug (head librarian of MPL), and Milwaukee mayor Henry Maier and his administration became major partners in expanding the reach of branch libraries across its urban neighborhoods. MPL grew from thirteen isolated libraries to nine connected branch libraries through the coordinated branch library system by 1972. This paper analyzes the history of library expansion in Milwaukee during the 1960s. Goals of community engagement, partnership, and citywide circulation guided the development of branch library construction. However, the creation of these branch libraries in Milwaukee was interconnected with the existence of racial inequality and changing racial demographics in the social, political, and economic context of the African American population in the city. Site and budget decisions made in this context had long-term consequences for the nine new branch libraries in Milwaukee.

Contudo, a resistência a antibióticos tem aumentado globalmente, tornando o tratamento mais difí-cil e favorecendo a disseminação da bactéria. A supergonorreia é uma forma mais resistente e difícil de tratar com antibióticos comuns, devido à rápida adaptação e produção de enzimas que inativam os antibióticos pela bactéria. A Organização Mundial de Saúde (OMS) alertou, em 2021, sobre a resistên-cia antimicrobiana da gonorreia, tornando-se uma ameaça crescente à saúde pública global e recomendou programas de vigilância e desenvolvimento de novas terapias para tratamento. Em resumo, é necessário desenvolver novas terapias e monitorar a resistência a antibióticos da N. gonorrhoeae para con-trolar a disseminação da doença. Conclusão: A N. gonorrhoeae é uma bactéria que pode se tornar resistente aos antimicrobianos, o que a torna uma preocu-pação global. É necessário um compromisso político e financeiro para prevenir a doença, desenvolver uma vacina e detectá-la precocemente. O diagnóstico correto é essencial para evitar sequelas irreversíveis, e o desenvolvimento de novas formas de tratamento é urgente, uma vez que a ceftriaxona já não é tão eficaz em alguns casos. A resistência aos antimicrobianos é causada pelo uso irracional de antibióticos, falta de adesão às prescrições e controle de infec-ção inadequado. Os profissionais de saúde têm a responsabilidade de refletir sobre as consequências do uso indevido de antibióticos e a importância de medidas rigorosas para controlar sua distribuição.

Introdução: A laqueadura tubária é um procedimento cirúrgico que visa a contracepção definitiva em pessoas com capacidade reprodutiva. Consiste na interrupção e ligadura das tubas uterinas, impedindo a fertilização. A Lei nº 14.443/2022 trouxe três alterações importantes: redução da idade mínima para o procedimento de 25 para 21 anos, eliminação da necessidade de con-sentimento do parceiro e autorização para realizar a laqueadura no período do parto, desde que o desejo seja manifestado com, pelo menos, 60 dias de antecedência e respeitando as condições médicas da gestante. Essa lei repre-senta um avanço significativo no planejamento familiar. Objetivos: O objetivo deste estudo foi analisar os dados de nascidos vivos, laqueaduras realizadas e idade das mães no parto nos anos de 2019 a 2022, correlacionando-os com a autonomia no planejamento familiar proporcionada pela nova lei da laquea-dura. Métodos: Realizou-se estudo ecológico utilizando-se dados dos anos de 2019 a 2022 obtidos do Departamento de Informática do Sistema Único de Saúde (DATASUS), do Instituto Brasileiro de Geografia e Estatística (IBGE) e da plataforma Integrada de Vigilância em Saúde (IVISQ). As variáveis ana-lisadas foram: número de nascidos vivos, idade das mães no parto e número de laqueaduras realizadas. Não foi necessária a aprovação de um Comitê de Ética em Pesquisa, uma vez que os dados utilizados são de acesso público. O programa Microsoft Excel foi utilizado para tabulação e análise dos dados. Resultados: Registrou-se um total de 10.722.856 nascidos vivos, distribuídos da seguinte forma: 2.849.146 (26,57%), em 2019; 2.730.145 (25,46%), em 2020; 2.672.046 (24,92%), em 2021; e 2.471.519 (23,05%), em 2022. Em relação à idade das mães no parto, a faixa etária mais comum em todos os anos foi de 20 a 24 anos, com as seguintes proporções: 697.478 (24,33%), em 2019; 670.389 (24,36%), em 2020; 657.791 (24,46%), em 2021; e 596.681 (24,14%), em 2022. Quanto ao número de laqueaduras realizadas, registraram-se, respectivamente: 42.524 (30,03%), em 2019; 22.436 (15,84%), em 2020; 23.847 (16,84%), em 2021; e 52.811 (37,29%), em 2022. Conclusão: Este estudo observou tendên-cia de diminuição no número de nascidos vivos ao longo dos anos, possivel-mente relacionada ao aumento da participação das mulheres no mercado de trabalho e ao maior acesso ao planejamento familiar. As mulheres na faixa etária de 20 a 24 anos foram responsáveis pela maior proporção de nascidos vivos. Quanto ao número de laqueaduras realizadas, houve aumento signi-ficativo em 2022, mesmo em comparação com o ano de 2019, que registrou o segundo maior número total. Esse aumento pode ser atribuído ao maior empoderamento das mulheres em relação aos seus direitos reprodutivos e pode indicar um crescimento adicional em 2023, com a aprovação da nova lei da laqueadura, que garante direitos às mulheres nessa faixa etária com maior índice de nascidos vivos.

Introdução: A laqueadura tubária é um procedimento cirúrgico de esterilização feminina definitiva, com uma taxa de falha (índice de Pearl) de 0,1–0,3 a cada 100 mulheres por ano. A opção de realizar a laqueadura durante uma cesariana é uma escolha para mulheres que desejam evitar gestações futuras e já têm indicação de passar por um parto cesáreo. Nesses casos, a laqueadura é realizada durante o mesmo procedimento cirúrgico, evitando a necessidade de uma intervenção adicional invasiva no pós-parto. Objetivo: O objetivo deste estudo foi avaliar a evolução do número de partos cesáreos com laqueadura e sua distribuição nas regiões brasileiras, além de analisar a média de permanência hospitalar e a taxa de letalidade associada ao procedimento. Métodos: Realizou-se estudo transversal seriado relacionado aos partos cesáreos com laqueadura tubária realizados no Brasil entre janeiro de 2016 e dezembro de 2022. Os dados foram coletados do Sistema de Informações Hospitalares (SIH), disponível no site do Departamento de Informática do Sistema Único de Saúde (DATASUS). As variáveis selecionadas foram: parto cesáreo com laqueadura tubária, autorizações de internação hospitalar (AIH), média de permanência e número de óbitos. Resultados: Durante o período de estudo, realizaram-se 285.565 partos cesáreos com laqueadura no Brasil. A Região Sudeste concentrou a maioria dos casos (47,09%), seguida por Nordeste (19,94%), Centro-Oeste (12,20%), Norte (10,61%) e Sul (10,14%). Observou-se um aumento progressivo no número de AIH, com taxa de crescimento de 81,07% entre 2016 e 2022. Nos últimos 6 anos, registraram-se 99 óbitos relacionados ao procedimento, totalizando uma taxa de letalidade de 0,03%. A média de permanência hospitalar para as puérperas após o parto cesáreo com laqueadura tubária foi de 2,7 dias. Conclusão: Observou-se expressivo aumento no número de esterilizações nos últimos 6 anos, o que pode ser justificado por diversos fatores, como mudanças culturais e dinâmicas familiares no Brasil. Os procedimentos foram concentrados principalmente na Região Sudeste, que tem a maior densidade demográfica do país e abriga grandes metrópoles. Além disso, constatou-se baixa taxa de letalidade associada ao procedimento, assim como média de permanência hospitalar semelhante à do parto cesáreo sem laqueadura, indicando que, em média, não há alteração no prognóstico para as mulheres que optam pela laqueadura periparto. No entanto, é importante lembrar que a laqueadura é um procedimento com altas taxas de insucesso na reversão, devendo ser considerada com cautela e discutida em conjunto com um médico especialista para esclarecer todas as dúvidas sobre o procedimento.
