В статье рассматривается разработка технологической схемы отработки наклонных залежей с углом падения от 20 до 35 градусов на примере Жиландинского месторождения с использованием камерно-столбовой системы. Ухудшение геомеханических условий, вызванное неправильными параметрами системы разработки, требует корректировки этих параметров. Для решения этой проблемы было проведено моделирование массива горных пород с использованием метода конечных элементов. В результате были определены главные сжимающие и растягивающие напряжения в зависимости от глубины отработки. Также был проведен расчет параметров междукамерных целиков с учетом различных горнотехнических факторов. Анализ результатов численного моделирования позволил определить допустимые параметры очистной камеры и междукамерного целика в зависимости от угла залегания. Было установлено, что междукамерный целик классической вертикальной формы допустим только при угле падения рудного тела до 25 градусов. Новая технология отработки наклонных залежей с углом падения 20-35 градусов с использованием камерно-столбовой системы была разработана на основе исследований Жиландинского месторождения.

В Казахстане тема переработки хлопковых отходов очень актуальна в современных условиях. Учитывая, что Казахстан является одним из крупнейших производителей хлопка в мире, на повестке дня стоит вопрос утилизации большого количества стеблей хлопчатника и других отходов, образующихся после сбора хлопка. Неэффективная утилизация этих отходов приводит к серьезным экологическим проблемам, таким как загрязнение почвы и воды, а также выбросы парниковых газов при их сжигании. Кроме того, отсутствие эффективных методов переработки лишает страну возможности использовать хлопковые отходы для производства ценной продукции, такой как целлюлоза, ограничивая экономический потенциал региона. Таким образом, разработка и внедрение новых эффективных технологий переработки хлопковых отходов в Казахстане имеет не только экологически и экономически актуальное, но и стратегическое значение для устойчивого развития страны. Переработка стеблей хлопчатника и других отходов в лигноцеллюлозу и целлюлозу может стать источником новых экономических возможностей как для мира, так и для Казахстана, где интенсивно выращивается хлопок. Переработка стеблей хлопка и других хлопковых остатков помогает сократить количество отходов, которые обычно выбрасываются в мусор или массово сжигаются после сбора хлопка. Решением этих проблем может стать переработка этих отходов и получение из них ценной продукции во избежание глобального потепления и других негативных последствий, угрожающих окружающей среде.

Проблемы, с которым приходится сталкиваться горнодобывающей промышленности для достижения утилизации отвальных хвостов в соответствии с принципами экономики замкнутого цикла, включает в себя улучшение довольно ограниченных знаний о минералогии, концентрации примесей и объём хвостов в хвостохранилищах. Также необходимо разработка технологий, чтобы сделать процесс экономически целесообразным. Для улучшения показателей операции измельчения и оказать существенное влияние на обогащение ценных компонентов было изучена влияния ультратонкого измельчения на степень раскрываемости медных минералов отвальных хвостов. На основании оптико-минералогических исследований установлено, что абсолютно раскрытые зерна халькопирита составляют не более 35 % от общего количества зерен, их размер в основном (на 60 % отн.) в пределах класса 10-45 мкм. Анализ ситовых характеристик хвостов после ультратонкого измельчения показывает, что наибольшая концентрация меди приходится на самый тонкий класс -0,006+0 мм, что свидетельствует о высоком раскрытии медных минералов за счет ультратонкого измельчения. Флотационные тесты по определению влияния степени ультратонкого измельчения показала, что с увеличением тонины помола по классу крупности – 0,045 + 0 мм до 86 % повышается извлечения меди с 66,49 до 73,52 %; золота 71,07 до 77,78 %; серебро 70,29 до 76,71 %.
SEMI-EMPIRICAL INVESTIGATION OF ZINC(II) SALICYLATE. COMPARISON WITH X-RAY STRUCTURE.
Authors: Akatyev N.
Published: October 2024

Zinc salicylate dihydrate (Zn(HSal)2·2H2O) is an organic-inorganic hybrid compound known for its wide range of applications. In this article, a detailed semiempirical study of zinc salicylate is presented, focusing on its structural, electronic, and thermodynamic properties. The PM3 method, known for its computational efficiency and reasonable accuracy, was used to model the molecular structure and compare with the experimentally obtained properties of Zn(HSal)2·2H2O. Based on the obtained calculation results and available experimental data published in the literature, it was found that semi-empirical calculations involving the solvent effect (H2O) agree well with data from X-ray diffraction analysis, while calculations for the gas phase do not agree with experimental data with the required accuracy. Quantum chemical descriptors such as HOMO-LUMO energies, energy gap (ΔEgap), electronegativity (χ), global hardness (η), softness (σ), dipole moment (μ), electrophilic (ω) and nucleophilic (ε) indices were also calculated. The results show that the PM3 method effectively captures the essential features of zinc salicylate, including its geometry and electronic distribution. The obtained results also provide valuable insights into the semi-empirical modeling of organometallic compounds and highlight the usefulness of the PM3 method in predicting the behavior of complex molecular systems.

Authors: Kopylov N.I. , Omarov Kh.B.
Published: October 2024

This article provides an analytical review of scientific and technical developments in the processing of solid arsenic-containing materials. Hydro-, pyrometallurgical and combined methods for extracting arsenic from dust, sublimates, and sludge from metallurgical production are considered. The most acceptable technologies seem to be those in which arsenic is removed from the process at the preliminary stage of processing in the most stable, non-toxic form - arsenic sulfides, which exist in nature as orpiment and realgar minerals. Studies conducted at the Zh. Abishev Chemical and Metallurgical Institute (Karaganda, Republic of Kazakhstan) and the Gidrotsvetmet Institute (Novosibirsk, Russian Federation) on products from a number of arsenic-containing raw material deposits for the removal of arsenic by oxidizing-sulfidizing roasting in a shaft-type furnace have shown the promise of this technology. The removal of arsenic from roasting products was 97-98.5%, simultaneously with the production of compact sulfide material with an arsenic content of 60-70% that does not require special disposal.

How universities can support Aboriginal and Torres Strait Islander peoples to achieve self-determination and improved wellbeing.
Authors: Callaghan Paul
Published: October 2024

The right to self-determination is enshrined in international law, affirming Aboriginal people have the right to make decisions about matters that affect their lives, including meeting their social, political, cultural and economic needs. This paper explores the role of universities in supporting Aboriginal self-determination, including an examination of the importance of the social and cultural determinants of wellbeing and the impacts of assimilation on Aboriginal people’s ability to live in accord with cultural traditions. Insights into how universities can create more culturally appropriate learning environments are also reviewed with a particular focus on the fundamental differences between Western and Aboriginal culture, pedagogy, epistemology, ontology, and axiology. The paper suggests that by undertaking a process of truth telling, universities will be able to create improved learning and research environments for Aboriginal students and staff that better support self-determination. By doing this, universities will leverage their unique position of influence to create improved wellbeing for Aboriginal people and the nation as a whole.
This is an invited article based on a HERDSA keynote address, which was presented at the 2024 conference held in Adelaide, 8-11 July. Dr Callaghan was also invited to provide a video introduction to the article. The video link may be found on the ASRHE journal site next to the link to the PDF.

Published: October 2024

Objective: While there is a close relationship between celiac disease (CD) and intussusception, it is not yet clear whether the detection of intussusception in children requires physicians to always screen for CD. In our study, we aimed to determine the frequency of CD in children with intussusception and to find the answer to whether CD screening is necessary for every child with intussusception.
Methods: The study included 50 symptomatic pediatric patients diagnosed with intussusception who were followed up and treated in the Health Sciences University Gülhane Training and Research Hospital Pediatric Surgery Clinic between 2020–2023. CD screening was performed in patients followed up with a diagnosis of intussusception.
Results: The mean age of the patients was 3.61 ± 2.02 years, and 33 (66%) were male. Of 62 intussusceptions observed in 50 patients, 46.8% were ileo-ileal, 35.5% ileo-colic, 11.3% jejeno-jejunal, 4.8% colo-colic, and 1.6% recto-sigmoid. CD was diagnosed endoscopically in three (6%) patients with an intussusception diagnosis and an anti-tissue transglutaminase level > 200 IU/ml. Intussusceptions in 43.5% of the patients were reduced by hydrostatic reduction, 41.9% spontaneously, 9.7% laparotomically, and 4.8% laparoscopically. A single intussusception attack occurred in 82% of patients; 14% had two, 2% had three, and 2% had four. No significant correlation was found between the number of intussusception attacks and the presence of CD (p = 0.34). There was also no relationship between the type of intussusception and age (p = 0.74), gender (p = 0.24), or treatment (p = 0.12) or between the presence of CD and gender (p = 0.26), age (p = 0.68), or type (p = 0.28) of intussusception.
Conclusions: CD is more common in symptomatic children with intussusception than in healthy children. Screening pediatric patients with idiopathic intussusception for CD may reduce the recurrence of intussusception and complications and morbidities that may occur due to a delayed CD diagnosis.

Published: October 2024

Objective: Patients with Noonan syndrome (NS), who may need various surgical interventions throughout their lives, need to be evaluated carefully in the preoperative period due to the risk of bleeding diathesis. There is a limited number of studies evaluating bleeding diathesis in patients with NS. In this study, we aimed to determine the frequency of bleeding diathesis in patients with NS and to evaluate the place of thromboelastography (TEG) in determining the risk of bleeding.
Method: In our study, bleeding score and coagulation test results obtained from the files of 12 patients with NS were evaluated.
Results: The most frequently detected factor deficiency is vWF deficiency (41%), followed by platelet dysfunction (33%). Two cases with a bleeding score of 2 or above were detected, and in one of them, both platelet dysfunction (response to epinephrine in platelet aggregometer, 7%) and vWF deficiency (vWF Ag: 20%), and in the other case, mild Factor VII deficiency (17%) were detected. TEG results of nine patients were normal. TEG abnormality was detected in three patients and 2 of them had bleeding phenotype.
Conclusion: As a result, although laboratory examinations in patients with NS often yield values consistent with bleeding diathesis, bleeding event does not occur in most patients. We suggest that with the use of the TEG method, the risk of bleeding can be predicted and unnecessary treatments can be prevented.

Thermal, mineral and thermomineral waters of the Prijedor region
Authors: Ećim Bojan
Published: October 2024

Mineral, thermal and thermomineral waters, as a unique natural treasure, are used mostly in spas. They can be a significant source of long-term wealth, provided that a strategy for their development and use is devised in accordance with the possibilities of modern techno-economy and general progress. There is a chance, because in the world, due to the exhaustion of resources and the disruption of the ecological balance, the direction of thedevelopment of clean technologies and the production of high-value products is increasingly emphasized. This direction of development is also forced by the already limiting exhaustion of living soil and drinking water, that is, geological and biological treasures, because nature is largely already incapable of returning the processes to their original state and renewing them with the previous gifts. These sources are becoming more and more scarce, geologically deeper, poorer in terms of abundance, less favorable in terms of quality and generally more expensive. In this area, the only Spa Mlječanica was formed at the location of natural occurrences of cold highly mineralized water with a temperature of 13 to 14oC, very rich in H2S gas. In addition, the thermomineral water of Lješljani, which has a high pH value of 11.9 and belongs to hyperalkaline waters, has the greatest perspective, which is also the most basic water in the Republic of Srpska. This work was done as a memorial to my late colleague Ljubinko Protić, B.Sc. geology. The work consists of his research in the Ljubija metallogenetic area, and I am honored to have been his collaborator and made a modest contribution to it.

Extraordinary events (floods and accidents) of RWSS Rzav until now
Authors: Radojević Milijanko , Dimkić Dejan
Published: October 2024

The public company Rzav, founded in 1987, takes care of the work of the Regional System Rzav, which supplies consumers in the municipalities of Arilje, Požega, Lucani, Čačak and Gornji Milanovac for more than 30 years. The previous work of RVS Rzav is characterized by the orderly supply of high-quality drinking water to consumers. Water transport through the distribution system is predominantly gravitational, with relatively moderate pressures and no sudden changes in flow.

Published: October 2024

For gravity sewerage system it is necessary to establish proper system of heights. The proper realization of designed pipelines' slope and the heights of their end points require system of heights adapted for every single sewerage system. The link points of sewerage system should be treated as the given points which define the datum of height system. Before establishing the system of heights for the purpose of sewerage system realization it is necessary to check the actual heights of given points and the height differences between them. In this paper some results are given based on the discussion of the relation between tolerance, heights of points and height differences from the aspect of height network designed for sewerage systems realization.

Authors: Victoria Hasheela
Published: October 2024

Even though Fintech is also transforming financial inclusion in Africa, its influence is not well studied. This systematicliterature review studied the status quo of Fintech in Africa. Our study focused on the following factors: adoption affectors, opportunities Fintech provides, and the challenges documented to have been faced so far, based on academic literature. The study found that Fintech is playing a major role in the improvement of financial inclusion in the region, as it has created opportunities for the unbanked population. It has also provided easy access to remittances and reduced money crimes by providing secure ways of transferring money through mobile phones. The study, however, revealed that Africa still faces various challenges, such as poor financial infrastructures, financial illiteracy, lack of awareness, and poor internet connections in rural areas, among others. The study contributes to the existing body of knowledge on financial inclusion. It also offers insights on best practices to guide fintech players regarding areas to focus on to increase financial inclusion.

Mutterschutz nach Fehlgeburt
Authors: Friedlein Nicole
Published: October 2024

Das BVerfG hat mit Beschluss vom 21. August 2024 die Verfassungsbeschwerde mehrerer Frauen, die eine Fehlgeburt nach der 12., aber vor der 24. Schwangerschaftswoche erlitten haben, nicht zur Entscheidung angenommen. Damit ließ das BVerfG die zentrale materiell-rechtliche Frage offen, ob das MuSchG Frauen nach einer Fehlgeburt von Verfassungs wegen schützen muss. Der folgende Beitrag geht dieser Frage nach und kommt zu dem Ergebnis, dass die aktuelle Schutzfristregelung aus § 3 Abs. 2 bis 4 MuSchG gegen Art. 3 Abs. 1 GG i.V.m. Art. 6 Abs. 4 GG verstößt. Zwar ist eine verfassungskonforme Auslegung möglich. Gleichwohl sollte der Gesetzgeber den Mutterschutz nach Fehlgeburt ausdrücklich regeln, um Betroffene effektiv zu schützen.
"MULAS DO TRÁFICO" SUL-MATO-GROSSENSE
Authors: Petroni de Moura Marco Aurélio
Published: October 2024

Através de uma pesquisa bibliográfica com os marcadores “narcotráfico”, “Direitos Humanos”, “Vulnerabilidades Sociais” e da análise de todas as ocorrências de tráfico de drogas registradas pela Polícia Rodoviária Federal (PRF) no Estado de Mato Grosso do Sul em 2022, o presente trabalho procurou identificar e analisar as principais vulnerabilidades e características socioeconômicas encontradas entre as pessoas presas transportando drogas (denominadas “mulas do tráfico”) flagradas pela PRF no Mato Grosso do Sul, em 2022, com o objetivo de contribuir com o meio acadêmico e apontar políticas públicas para a proteção e promoção sociais. Entre as principais vulnerabilidades e características socioeconômicas observadas, a baixa escolaridade, o desemprego, a informalidade e a ocupação de trabalhos de baixa especialização são recorrentes. O estudo também identificou que apesar da maioria dos presos serem do gênero masculino, é preocupante o número de mulheres cada vez mais jovens que se envolvem com o transporte de drogas. Políticas públicas especialmente na área da educação e profissionalização emergem como essenciais para um possível afastamento da delinquência.
COOPERAÇÃO ENTRE A POLÍCIA RODOVIÁRIA FEDERAL E AS DEMAIS FORÇAS DE SEGURANÇA DO MUNICÍPIO DE CAMPO GRANDE-MS NO COMBATE AO TRÁFICO DE DROGAS.
Authors: De Oliveira Figueiredo Vinícius
Published: October 2024

Este estudo foi desenvolvido com o objetivo de analisar os resultados de apreensões de drogas frutos da cooperação entre a Polícia Rodoviária Federal e outras forças de segurança em Campo Grande-MS. O narcotráfico é o principal tipo de crime transnacional na região, e o Mato Grosso do Sul, com 1.517 km da linha divisória e 45 municípios dentro da faixa fronteiriça, é um estado particularmente afetado. Embora as forças de segurança federais, estaduais e municipais sejam responsáveis por coibir atividades ilegais que possam impactar a estabilidade do país, a integração ainda é um desafio. O artigo analisa se houve evolução ou estagnação nas ações cooperadas voltadas ao combate ao narcotráfico entre as instituições policiais no Estado do Mato Grosso do Sul, e se a cooperação estabelecida contribuiu para o aumento no volume de drogas apreendidas pela Delegacia da PRF em Campo Grande, após identificação de quais ocorrências foram fruto de trabalho integrado no período de 2020 a 2022. O número de apreensões de cocaína e maconha em Campo Grande foi recorde em 2022, evidenciando a complexidade do combate ao narcotráfico na região.
El incansable cooperativista de Excélsior (Testimonio de vida y lucha de Rafael de la Huerta Reyes)
Authors: Serna Ana María
Published: October 2024

Este volumen registra la historia de vida de Rafael de la Huerta Reyes, linotipista y presidente del Consejo de Administración del periódico Excélsior desde el año 2000 hasta su muerte en 2020. Desde el punto de vista de un trabajador de los talleres del diario, don Rafael narra en este testimonio cómo vivieron los socios de la Cooperativa Excélsior la amañada venta del periódico y cómo se les defraudó. Alrededor de esta problemática central, la vida de Rafael nos transporta a los espacios urbanos y a los sufrimientos personales de los habitantes depauperados de la ciudad de México en la segunda mitad del siglo xx. Nos acerca al extinto oficio de linotipista, que fue un pilar de la comunicación del mundo hasta la proliferación de los procesos digitales. Rafael vive y narra de cerca la podredumbre de una empresa periodística mexicana constituida en cooperativa desde los años treinta. Explica con detalle las luchas por defenderla de la corrupción de Regino Díaz Redondo y de una venta espuria en la que no se reconoció la categoría de socios de todos los cooperativistas. Con una capacidad narrativa vivaz y llena de detalles que, como todo testimonio personal valiente y honesto, regresa siempre a los puntos traumáticos de su vivencia personal, este relato es un viaje fascinante a la historia social del periodismo mexicano, a la importante experiencia mexicana de la organización en cooperativas y a la vida de un hombre incansable con un exquisito sentido del humor.
