Published: July 2024

Background: Malaria induces a recession of the near point of convergence and a reduction of the amplitude of accommodation of the  eye with symptoms such as blurred vision at near, difficulty reading, asthenopia, exophoria at near, and low accommodative convergence  ratio occurring, all these symptoms lead to an interference in visual functioning and performance. Artemether- Lumefantrine anti-malaria drug is widely used and very effective as a first line treatment for uncomplicated plasmodium falciparum  malaria infection. There is a need to determine if artemether-lumefantrine can reverse the effects of malaria on the amplitude of  accommodation and near point of convergence.
Methods: This was a clinical study carried out using the convenient sampling method at  the medical center and department of Optometry teaching clinic of the Federal University of Technology Owerri, Imo State, Nigeria to  evaluate amplitude of accommodation and near point of convergence after treatment with artemether-lumefantrine. Informed consent  was obtained from all subjects that participated in the study and ethical clearance from the Ethics Committee of the School of Health  Technology, Federal University of Technology, Owerri. 143 subjects aged 18 to 30 years diagnosed with malaria were recruited for the  study. The amplitude of accommodation was measured using the push-up to blur method with an accommodative target, and near point  of convergence was determined using the push-up to break and recovery method with an accommodative target. Both measurements  were taken after the diagnosis of malaria was made through laboratory analysis and before the administration of the drug. After drug administration, amplitude of accommodation and near point of convergence measurements were repeated 24-, 48-, 72-, and 336 hours.  Effects of drug administration on parameters were analyzed using T-test and ANOVA.
Results: There was a significant increase in the  amplitude of accommodation with time following administration of artemether-lumefantrine drug combination (p<0.001) while near  point of convergence was not affected (p>0.05).
Conclusion: Artemether-lumefantrine used for the treatment of malaria countered the  effect of malaria parasite on amplitude of accommodation by increasing it but had no significant effect on near point of convergence.
Thoughts about the 2023/4 Malawi National Health Budget
Authors: Muula Adamson S.
Published: July 2024

At 12% of the total national budget, the proposed 2024/24 health budget is most likely the highest ever in Malawi. I say “most likely” or probably, because I have not been careful enough to review what was the country’s health budget in the 1960’s, 80’s, or the 90’s. In addition, in the Malawi context, the budget as approved by the National Assembly and assented to by the State President, doesn’t always mean that it will be followed to the letter through treasury disbursements to Ministries, Departments and Agencies (MDAs). But 12% isn’t lower when one looks at the other sectors (defence, homeland security, foreign affairs, education and agriculture) which the same national fiscus seeks their attention.
Enhancing sexual and reproductive health services uptake in Sub- Saharan Africa: the role of community Pharmacists in promoting self-care interventions: a systematic review
Authors: Ndayishimye S. , Oladokun A. , Mukanyangezi M. F.
Published: July 2024

BACKGROUND: Low uptake of sexual and reproductive health (SRH) services is influenced by system-level and socio-cultural barriers. Despite the potential of community pharmacists to offer self-care interventions on SRH, their role remains underutilized in the sub-Saharan Africa (SSA) region due to a lack of guidelines and awareness. 
METHODS: A systematic search strategy was employed to identify peer-reviewed articles published in the English language between 2013 and 2023. The search was conducted from January 2023 to June 2023 in Research4life, PubMed, and Cochrane databases. Eligible studies focused on community pharmacists' interventions related to self-testing, self-management of sexually transmitted infections (STIs), self-abortion management, Human Immunodeficiency Virus (HIV), pre- and post-exposure prophylaxis (PrEP and PEP), and self-management of contraception in SSA. 
RESULTS: The initial database search produced 7487 articles after removing duplicates, out of which 65 articles were appraised for full-text screening after the title and abstract screening. Ultimately, 11 articles were included in the review, covering selfcare interventions for sexual and reproductive health services, including modern contraceptives, pre-exposure prophylaxis (PrEP), medical abortion pills, and HIV self-testing. The studies highlighted that community pharmacists play a crucial role in offering counseling, education, and faster service delivery, particularly for adolescent girls and young women. 
CONCLUSION: Community pharmacists in sub-Saharan Africa contribute in promoting access to, and use of self-care interventions for sexual and reproductive health services. Governments and policymakers should prioritize the development of standardized guidelines to support community pharmacists in delivering quality SRH services.
Borderline Personality Disorder: Stigmatisation experiences of accessing and participating with frontline services in England
Authors:   , Bradbury Donna
Published: July 2024

Borderline personality disorder (BPD) is one of the most stigmatised of all psychiatric diagnoses. Frontline service professionals regard this diagnostic group as challenging, manipulative, time wasters, a drain on services and attention seekers which results in people with the diagnosis being subject to stigmatising and negative attitudes, which is also reflected in people receiving unequal care and support or exclusion. The stigma associated with this diagnosis remains as the catalyst in creating barriers to accessible care, life quality and the continuation of discriminatory practices. The current research presents the experiences of individuals with a BPD diagnosis in accessing and participating with frontline services in England. The current research focuses on investigating stigmatisation in frontline services and provides recommendations for reducing such stigmatisation. This qualitative research was conducted using a social justice constructivist grounded theory approach. Semi structured narrative interviews were carried out with a total of eleven participants in varying locations across England. The data analysis identified five main themes: stigmatisation and awareness, the power of language, service provision, professional control and reclaiming power and identity. The findings evidenced that stigmatisation, negative attitudes and exclusion of people with a BPD diagnosis was experienced throughout physical, mental and public protection services. This study makes a direct contribution to this area of research from the lived experience perspective.

Authors: Couto Gualter , Chissingui Victor
Published: July 2024

Este artigo utiliza os modelos de troca e ordem hierárquica usando os dados de firmas não financeiras no mercado português sobre um horizonte de tempo de 10 anos (1996/2005), por meio do método de estimativa dos mínimos quadrados generalizado (GLS). Neste trabalho determina-se que os atributos da dívida reflectem a importância extrema em determinar a estrutura capital, negligenciando o factor do risco económico (volatilidade), desde que os resultados encontrados não permitem apoio na literatura financeira actual. Os resultados sugerem que os activos de tangibilidade, activos de crescimento e o lucro se relacionam de forma negativa com a dívida. Por sua vez, os factores como a dimensão da empresa, o imposto de dívida e liquidez têm uma relação inversa com os primeiros três atributos.
Pedagogia ideal da aretêna morte de sócrates
Authors: Moutinho Barroso Paulo
Published: July 2024

Este artigo sublinha a importância da aretê como ideal pedagógico e prática cultural na formação do indivíduo. Para isso, reporto-me à cultura clássica e ao legado histórico e referencial que as sociedades contemporâneas e ocidentais podem usufruir. Designadamente a um dos episódios mais marcantes do apogeu da racionalidade na Antiga Grécia: a morte de Sócrates, segundo o Críton de Platão, como pedagogia ideal da aretê Nesta perspectiva eminentemente teórica, a metodologia que melhor conduz à prossecução do objectivo proposto baseou-se na releitura, análise, compreensão e interpretação de várias obras de referência consideradas indispensáveis para a mencionada temática. Os resultados deste meu artigo reflexivo passam essencialmente pela conclusão de que a aretê serve como ideal pedagógico e prática cultural de um “eu” conforme determinados padrões conceptuais de excelência. Assim, considero que um dos maiores méritos da cultura clássica foi ter percebido que o homem é educável porque, precisamente, é modificável. A possibilidade de modificar o homem faz parte do projecto Paidleia, um programa para a perfectibilidade ou excelência. Tratase de um mérito muito trabalhado, porque o conceito de aretê resume a vida de qualquer homem que procura, durante a sua curta existência, ser melhor não só face ao que foi no dia anterior, como também face aos outros.

Critical Pedagogies for Reappraising Indigenous Knowledge and Diversity in Rural Peru
Authors: Espinal-Meza Silvia
Published: July 2024

Rural schools and communities in Peru are rich in cultural diversity in Indigenous languages and traditions, but rural areas remain the most disadvantaged regions. Peru’s educational policies are neoliberal and have hindered opportunities for the rural population to receive a high quality education with a critical reappraisal of their cultural backgrounds. Within this scenario, critical perspectives in education have emerged from the voices of historically marginalised educational actors: rural teachers. Two rural teachers from small towns in Cusco and Ayacucho (in the southern highlands of Peru) participated in narrative research to explore their practices of social justice in education. The aim of this paper is to examine their practices through critical pedagogies. The findings reveal that a crucial role of the Indigenous language, Quechua, is in making an inclusive reappraisal of the local culture. The teachers sought to empower their pupils by applying Freirean concepts of critical consciousness and dialogue through creative activities. They acknowledged the role of parents and the community who value diversity and local culture and support their critical pedagogical practices in schools. In this case, social justice in education was addressed by valuing Indigenous culture and placing it in dialogue with Western knowledge.

Authors: B Nithya Sree  , Lakshmi M R  , B Swetha Sree  , B Nandini  , H Shravani
Published: July 2024

The research explores how machine learning methods can aid in the early identification of Parkinson's disease. It examines two distinct aspects: hand movements and vocal features. Unique datasets tracking the progressive changes in these symptoms over time are explored. Specialized techniques are employed to extract the most distinguishing hand motions and speech characteristics, which serve as potential biomarkers. In contrast to conventional approaches that depend exclusively on a single feature, this multi-modal approach combines both hand movement and voice biomarkers into a unified computational model. Overall, the research illustrates the promising potential of machine learning tools to enable earlier intervention for medical purposes, while emphasizing that the focus remains on aiding clinicians rather than replacing specialized assessments. The study does not aim at individual diagnosis but rather explores avenues for supporting healthcare professionals. Future research endeavors involve developing multi-modal models that encompass a wide range of aspects associated with this complex and variable condition.

Published: July 2024

В статье рассматриваются способы и методы проведения геодинамического и геомеханического мониторинга на месторождениях полезных ископаемых, разрабатываемых открытым, подземным и комбинированным способами. Для полноты извлечения минерального сырья в эксплуатацию активно вводятся залежи полезных ископаемых на больших глубинах и залегающих в сложных горно-геологических условиях. Здесь ожидаются большие осложения, связанные с геомеханической и геодинамической ситуациями, в результате которых могут разрушаться промышленные объекты, жилые дома и сооружения, а это, в свою очередь, приведет к большим финансовым убыткам горнодобывающих предприятий, человеческим потерям и социальной нестабильности в горнорудных районах. На основе данных, полученных из геодезических, геофизических, аэрокосмических исследований, горнорудные преприятия выполняют моделирование геомеханических и геодинамических процессов для принятия управленческих решений по нивелированию технологического производства для отвода негативного воздействия на природную среду, в целях обеспечения безопасной отработки месторождений полезных ископаемых.

Kazakhstan is one of the countries where the mining industry is developing at a rapid speed, therefore, the article discusses information on the methods for conducting geodynamic and geomechanical monitoring at mineral deposits developed by open, underground and combined methods. To complete the extraction of mineral raw materials, mineral deposits are actively put into operation at great depths and occurring in difficult mining and geological conditions. Here, large complications are expected associated with geomechanical and geodynamic situations, as a result of which industrial facilities, residential buildings and structures may collapse, and this, in turn, will lead to large financial losses for mining enterprises, to human losses and social instability in mining areas. Based on data obtained from geodetic, geophysical, aerospace data, mining enterprises perform simulations of geomechanical and geodynamic processes to make management decisions on leveling technological production to remove the negative impact of the natural environment in order to ensure the safe development of a mineral deposit.

В статье рассматривается выраженное блоковое строение, обусловленное широким развитием региональных разломов и секущих их более мелких поперечных и диагональных трещин. Подтверждена актуальность проведения поисково-детальных сейсморазведочных работ методом общей глубинной точки в двухмерном и трехмерном пространстве с целью уточнения особенностей тектонического районирования между структурами и выявления новых, возможно перспективных объектов на нефть и газ в Сурхандарьинском нефтегазоносном регионе. Настоящая работа посвящена изучению тектоники и выявлению перспектив нефтегазоносности палеогеновых отложений Западного блока Сурхандарьинской мегасинклинали. На основе анализа и исследования результатов геологических, геофизических наблюдений и, особенно, материалов по пробуренным скважинам дается современное тектоническое строение и новая тектоническая схема районирования структур, рассматриваются особенности строения ряда локальных складок и перспективы их на нефтеносность.

The article considers a pronounced block structure, due to the wide development of regional faults and smaller transverse and diagonal ones that cut them. The relevance of carrying out search and detailed seismic surveys using the common depth point method in 2D and 3D is also considered in order to clarify and confirm the features of tectonic zoning between structures and identify new possibly promising objects for oil and gas in the Surkhandarya oil and gas region. This work is devoted to the tectonics and the prospect of oil and gas potential of the Paleogene deposits of the Western block of the Surkhandarya megasyncline. Based on the analysis and study of the results of geological, geophysical and especially materials of drilled wells, a modern tectonic structure and a new tectonic scheme for zoning structures are given, structural features of a number of local folds and their prospects for oil are considered.

С ростом срока эксплуатации все большее число нефтяных месторождений переходит на насосную добычу углеводородного сырья. Более половины фонда действующих скважин в мире оснащено скважинными штанговыми насосными установками. В данной статье про- веден анализ работы скважинных штанговых насосных установок, который показал, что на первом месте находятся отказы, связанные с обрывом колонны штанг, на втором – отказы, связанные с неисправностью клапанных узлов и на третьем месте отказы из-за негерметичности пары «ци- линдр – плунжер». При насосном способе добычи нефти с применением скважинных штанговых насосных установок порядка 15-30% остановок нефтяных скважин на текущий ремонт связаны с их замено

Бұл мақалада штангалық ұңғымалық сорғы қондырғыларының жұмысы талданады және ол бірінші кезекте штангалар бағанының үзілуіне байланысты істен шығулар, екінші орын- да – клапан түйіндерінің дұрыс жұмыс істемеуіне байланысты істен шығулар және үшінші орында «цилиндр – плунжер» жұбының тығыздығына байла- нысты дұрыс жұмыс істемеуі екенін көрсетеді. Мұнайды штангалық ұңғымалық сорғы арқылы өндіру кезінде шамамен 15-30% мұнай ұңғымаларының ағымдағы жөндеуге арналған тоқтаулар штангалық ұңғымалық сорғыны ауыстырумен байланысты болады

With the increase in the service life, an increasing number of oil fields are switching to pumping production of hydrocarbons. More than half of the fund of operating wells in the world is equipped with downhole rod pumping units. This article analyzes the work of downhole rod pumping units, and it shows that in the first place there are failures associated with the breakage of the column of rods, in the second place there are failures associated with the malfunction of valve assemblies and in the third place there are failures due to the non-tightness of the cylinder – plunger pair. During pumping oil production with the use of downhole rod pumping units, about 15-30% of oil well shutdowns for routine repairs are associated with the replacement of downhole rod pumping unit

The article highlights the results of field studies of Precambrian intrusive formations of Southern Ulytau. The relevance is determined by a new approach to the consideration of mineralogical conditions of ore bearing of complex-built shaft-shaped granite-gneiss domes of the Neoproterozoic Ulytau-Arganatinsky zone. This territory has a very complex geological structure with a wide age range of its geological formations. The intrusive formations of this zone form intrusive complexes of different composition and age, which, together with metasomatic granite-gneisses and migmatites, are genetically associated with the development of granite-gneiss domes. The Aktas, Zhaunkar, and Souktal intrusive complexes, together with volcanic rocks of the Koksui, Maytyubinskaya series, and the Karasuleimenovskaya Formation, compose fragments of the Late Riphean marginal continental volcanoplutonic belt
