Analyzing the techniques for restoring crankshafts of automotive vehicles
Authors:   Timirâzevskaâ selʹskohozâjstvennaâ akademiâ, Balabanov V.I. 
Published: October 2024

Characteristic defects of internal combustion engine crankshafts of automotive vehicles include wear of friction surfaces - journals, faces, grooves and threads, - as well as residual deformations and fatigue cracks. To eliminate defects, crankshafts are repaired using technological operations to restore the shape and location, linear and angular dimensions, as well as roughness, wear resistance and fatigue resistance of elements and surfaces. To analyze the restoration techniques of crankshafts of automotive vehicles the operating conditions, the authors considered the main defects and types of surfacing and spraying applied by means of electric arc, gas-flame, detonation, and plasma (induction and plasma-arc) methods. The authors note that to meet reliability requirements, the restored parts should have a ratio of hardness (НRСв /НRСн) and fatigue strength (G-1B/G-1H) higher than one as compared to new parts. However, no crankshaft restoration technique fully meets this requirement, because the wear resistance of new crankshafts in most cases is higher than that of restored parts. Based on the analysis of crankshaft restoration techniques, the authors determined the following effective ones: the finishing antifriction non-abrasive treatment (FANT) with the use of antifriction, wear-resistant and solid lubricant coatings applied to the parts using various methods. This technique increases wear and corrosion resistance, resistance to fatigue wear, and improves the running-in of the rubbing machine parts.

Authors:   Timirâzevskaâ selʹskohozâjstvennaâ akademiâ, Butorin V.A.
Published: October 2024

The main characteristic of the performance of submersible electric motors after overhauls is their reliability. To assess the compliance of reliability indicators of restored submersible electric motors with technical requirements for overhauls, various types of tests are used. The most acceptable of them is the bench test method based on a sequential failure analysis of the studied electric motors. To implement it, the specified parameters should be set. In this study, based on the use of technical requirements for the manufacture and repair of submersible electric motors, the authors determined the specified average operating times for failure of new electric motors (before the first overhaul) and after it. Bench tests were carried out for two batches of submersible electric motors: overhauled and non-overhauled. In each batch, 20 electric motors were studied. The experiment determined the standard deviation of the mean time between failures (MTBF) of new electric motors, which amounted to 3.54 thousand hours, after the overhaul - 2.37 thousand hours. The coefficients of variation were 0.3 and 0.34, respectively. The study results determined the values of the set parameters of the mathematical model, enabling the use of the method of successive failure analysis. The values included the set average MTBF before the first overhaul - 16 thousand hours; the set average MTBF after the overhaul - 12.8 thousand hours; the risks of the repair provider and the customer - 0.05; the set mean square deviation of the MTBF of electric motors before the first overhaul - 4.8 thousand hours; the set mean square deviation of the MTBF after the first overhaul - 4.8 thousand hours; the set mean square deviation of the MTBF after the overhaul - 2.37 thousand hours.
EMPLOYMENT OF WOMEN IN PAKISTAN
Authors:   Chief physician and independent researcher of ICMC “Dua Hospital” Islamabad, Bakanova Marina V.
Published: October 2024

Women’s employment in Pakistan has its own characteristics, which are associated both with the level of development of the country and with the local mentality. Standard Western practices remain insensitive to the majority of working women and therefore produce incorrect results. The patriarchal structure of society also contributes to limiting the work of women in a number of professions, but currently there are trends towards changing that situation. As in other countries around the world, working women face phenomena of discrimination at work that are similar to the world’s concerns and specific to Pakistan. Separately, one can note the situation with the lack of jobs for educated female youth, which is partially mitigated by the conditions of marriage for which a diploma is an additional part of the dowry. However, the issue of Pakistani women’s employment needs to be carefully studied with the creation of specific research methods to avoid “blind spots” and social archetypes, so that it will subsequently be possible to both create jobs and level out factors that complicate women’s employment.

Authors: Martirosyan M.
Published: October 2024

In this paper, a statistical analysis of the results from an experiment involving the two-point bending of a multi-layer rod using an optical fiber with specific parameters was conducted. Each parameter of the model was evaluated three times three times using method of least squares, method of moments, and maximum likelihood estimations. The hypothesis proposed in previous studies about the supremacy of the Weibull distribution for explaining the results of this experiment was refuted. Instead, the gamma distribution was found to be a suitable option too, as it significantly reduces the overall variance in the distribution when maximum likelihood estimates are used.

PRE-SERVICE MATHEMATICS TEACHER’S ABILITY IN DESIGNING MATHEMATICAL TASK: AN ANALYSIS OF LESSON PLANS
Authors: Mahfudy Sofyan , Mauliddin Mauliddin
Published: October 2024

Mathematical tasks have an essential role in the mathematics learning process. Well-designed mathematical tasks will provide a learning opportunity for students to develop their mathematical ideas. The ability of pre-service mathematics teachers to design mathematical tasks during their academic studies significantly influences how they teach in actual learning. One of the ways to investigate pre-service mathematics teachers' ability to design tasks is by analyzing the tasks in the lesson plans they proposed. This study aims to scrutinize the level of cognitive demand for mathematics tasks designed by pre-service mathematics teachers in their lesson plans to get a thorough understanding of their ability to design tasks. This descriptive qualitative research analyzed mathematical tasks in 25 lesson plans proposed by pre-service mathematics teachers using the framework developed by Stein and Smith (1998). The results of this study show that most pre-service teachers designed tasks with a lower cognitive demand classification with types of memorization and procedures without connections. The mathematical tasks designed by pre-service mathematics teachers also have yet to lead to argumentation and the development of mathematical ideas through exploration or doing mathematics. Thus, based on the findings in this study, designing mathematics tasks with the potential to promote students' mathematical understanding remains a challenge for pre-service mathematics teachers. This article discusses and presents the implications of research results and recommendations for designing mathematical tasks.

EXPLORING GREEN MARKETING PRACTICES: INSIGHTS FROM MARKETING MANAGERS ON ENVIRONMENTAL SUSTAINABILITY
Authors: Darekar Sheetal , Misal Satyavan , Bagul Shweta , Banerjee Sneha , Thakre Purva
Published: October 2024

Creating and promoting items according to their perceived or actual environmental sustainability is referred to as "green marketing." Two instances of green marketing involve highlighting the reduced emissions linked to a product's manufacturing process or using recycled materials in product packaging. Some companies might further position themselves as mindful businesses by giving a portion of their sales profits to environmental projects like planting trees. Green marketing is part of a broader trend toward socially and environmentally friendly business practices. Consumers are increasingly expecting companies to demonstrate their commitment to improving their operations while also following to various environmental, social, and governance (ESG) standards.To continue to achieve this, a lot of businesses will continue to send out social impact statements in which they transparently track their advancement toward these goals on a regular basis. Reducing the carbon emissions linked to the company's operations upholding strict labor laws both domestically and in foreign supply chains, and charitable endeavors aimed at benefitting the communities where the company operates are common examples of ESG-related improvements. Green marketing, while primarily referring to environmental measures, is increasingly being offered alongside with corporate governance and social goals. Based on a survey of 120 marketing managers, a collection of green marketing practices is identified in this article.

O FARDO DE SER: LEITURA COMPARADA EM “COM LICENÇA POÉTICA” DE ADÉLIA PRADO E “FORÇADAMENTE MULHER, FORÇOSAMENTE MÃE” DE DINA SALÚSTIO E ADÉLIA PRADO
Authors: Nascimento dos Santos João do , Manoel Monteiro Pedro , Aparecida Dal Cortivo Raquel
Published: October 2024

RESUMO: O presente trabalho consiste em analisar a crônica “Forçadamente Mulher, Forçosamente Mãe” da escritora Dina Salústio e o poema “Com Licença Poética” de Adélia Prado, na busca de comparar o eu lírico presente no poema, o qual reconhece o peso de carregar uma bandeira, o qual vem acompanhado por nascer mulher, e a personagem da crônica que sente o peso do ser mãe e do ser mulher, pois sua infância  é interrompida por uma gravidez indesejável. Michelle Perrot (2008, p.69), ressalta que a maternidade “é um pilar da sociedade e das forças dos Estados, torna-se um fato social”, marcando esse processo com uma condição da mulher, ideia que o patriarcado busca manter. Portanto, discutiremos a questão levantada pelo eu lírico sobre “carregar a bandeira” de ser mulher, enquanto que na crônica Paula, passa por situação de violência que obriga ela a ser mulher e mãe, e nessa perspectiva enfatizaremos quais são os enfrentamentos que os textos apresentam que tornam esse “ser” um peso para o sujeito mulher.
UMA ESCRITA SILENCIOSA: CONSIDERAÇÕES SOBRE A PALAVRA E O SILÊNCIO EM UM SOPRO DE VIDA, DE CLARICE LISPECTOR
Authors: Leila Borges Dias  , Barboza Ferreira Arthur
Published: October 2024

O artigo tece considerações sobre a palavra e o silêncio em Um sopro de vida, de Clarice Lispector. Reconhece, como já o fez parte da fortuna crítica, que a literatura clariceana envolve uma escrita “em diáspora”, qualidade relacionável às origens judaicas da autora. O artigo constata que a tradição judaica e sua hermenêutica repercutem em Um sopro de vida, na escrita silenciosa, que é tematizada, bem como na forma de uma suspensão temporal, atada à narração não linear presente nesse livro póstumo da autora. Destarte, observa-se que tema e forma estão atrelados no livro. Apontam-se ainda afinidades entre a escrita silenciosa tematizada e o caráter místico observável no livro. Tal caráter místico está ligado à busca angustiante de descortinar o mistério da vida, do tempo, da morte, vivida pela personagem Ângela Pralini, busca esta que culmina numa experiência extática que a leva a um “estado de graça”. Malgrado as limitações e precariedades da palavra no que diz respeito a revelar o mistério, é ela a matéria-prima por excelência e, de fato, a única ferramenta à disposição para abordar o enigma da vida, do tempo, da morte, que agitam e inquietam tanto Ângela Pralini quanto a personagem nomeada Autor, as quais guardam afinidades com a própria autora.

Augusto Motta, 2023.

O presente trabalho pretende principal analisar como o aço concerne a uma liga
metálica integrada composta por Ferro e Carbono, com percentuais de carbono oscilando em
torno de 0,008% e 2,11%. Diferencialmente do Ferro-Fundido que apresenta liga de Carbono e
Ferro com o teor de Carbono elevado a 2,11%. Além disso, o aço estrutural EN 10025-2 S355
J2 N é aplicado em diversos segmentos da Engenharia, como em construção civil (edifícios e
pontes), estruturas offshore, equipamentos de mineração e torres de sistemas eólicos. O aço
ASTM-A36 dispõe vasta viabilidade no mercado, visto que apresenta baixo custo e boa
soldabilidade, gerando um imenso privilégio competitivo para a produção de peças. Nesse
sentido, buscamos efetuar o teste de dureza Vickers com o intuito de medir a dureza superficial
e observamos que ao colocar um indentador de diamante no molde piramidal, base quadrilátera
e ângulos com faces distintas de 136°, sobre a superfície do material, o mesmo não possui vasta
diferença entre os Aços A36 e o Aço S355J2+N. E Analisando a composição química dos Aços,
notamos que o aço S355J2+N possui algumas vantagens sobre o Aço ASTM A36 e apesar de
ser mínima, apresenta uma significativa melhora para algumas situações.

A Case Report on Paradoxical Emboli
Authors: You Li , Jason Wheeler
Published: October 2024

Venous Thromboembolism (VTE) is a major public health concern, affecting approximately 900,000 people annually in the United States. In rare cases, a Patent Foramen Ovale (PFO) may allow a venous thrombus to cross into the arterial circulation, causing a paradoxical embolism. This case report presents a 46-year-old male who developed left renal artery stenosis after a paradoxical embolism, likely triggered by a prolonged flight and binge alcohol consumption. The patient was found to have a moderate-sized PFO and renal infarction, confirmed by imaging studies. Despite initial anticoagulation therapy and a planned stenting procedure, intraoperative findings revealed only mild stenosis, leading to cancellation of the stent placement. The patient ultimately underwent PFO closure with an Amplatzer Talisman device. This case underscores the diagnostic challenges in managing paradoxical embolism and the need for individualized treatment, particularly concerning anticoagulation duration, the decision for PFO closure, and post-procedural antithrombotic therapy. Further research is required to establish optimal management strategies for cryptogenic embolic events.

Authors: A. Dnana Hussein , Azhar Noory Hussein
Published: October 2024

The current study was conducted to identify pathogenic E.coli that coexist with prostate cancer and characterize these bacteria based on some virulence genes using molecular techniques such as RAPD-PCR. The study was carried out on 200 samples isolated from prostate cancer patients in different hospitals in Maysan Province, Iraq. These samples were cultivated on traditional and specific media agars for the identification of certain pathogenic bacteria. These bacterial organisms were subjected to PCR targeting the 16S rRNA gene for the identification of these bacteria and the genes aac2, blaoxA-1, blaTEM, oxA48 for the detection of virulence factors of isolated bacteria. The results revealed the presence of 200 bacterial isolates, which included 65 (59.09%) E. coli, 20 (18.18%) Proteus mirabilis, 12 (10.9%) P. penneri, 10 (9.09%) Pseudomonas aeruginosa, and 3 (2.72%) Klebsiella pneumonia, 16 (32%) Enterococcus faecalis, 15 (30%) Staphylococcus hemolyticus, 9 (18%) S. lentus, 3 (6%) Aerococcus viridans, , and 7 (14%) Streptococcus uberis. The findings of 16S rRNA-PCR confirmed the results of conventional tools. The virulence genes were detected in the identified bacterial species. The study findings reveal a diverse community of bacterial species present in samples isolated from patients with prostate cancer with high virulence, detected by the presence of virulence genes.
Analysis of the composition of thrips (Insecta: Thysanoptera) in spontaneous vegetation and crops associated with peanut in Argentina
Authors: Dottori Carolina A. , Zamar Maria Inés , De Breuil Soledad
Published: October 2024

Peanuts (Arachis hypogaea L.) are a crop from tropical and subtropical regions.  Argentina is a significant producer and exporter, with the province of Córdoba concentrating ca. 84% of the peanut-cultivated area in the country. Thrips pose a threat to the crop by causing direct damage through feeding and indirect damage as vectors of orthotospovirus. Despite the importance of these insects and the crop, little is known about the diversity of thrips in the vegetation surrounding peanut crops in Córdoba province. The aim of this study was to expand knowledge on thrips diversity in the plant environment around peanut crops in fields located in Río primero, Río Segundo and General Roca counties (Córdoba, Argentina). Sampling was conducted during the 2021-2022 growing season. The adult trips were collected from spontaneous plants and crops neighboring the peanut, and they were prepared and identified using special keys. In 14 plant species, specimens of Frankliniella schultzei (Trybom), Frankliniella gemina Bagnall, Caliothrips phaseoli (Hood), Frankliniella occidentalis (Pergande), Thrips tabaci (Lindeman), Frankliniella frumenti Moulton, Arorathrips mexicanus (Crawford), and individuals from the genera Heterothrips and Hoplandrothrips were collected. Frankliniella schultzei was the most frequent and abundant species. Spontaneous plants and soybean crops contained thrips species able to transmit orthotospovirus. This study reports for the first time the presence of F. schultzei in Gomphrena pulchella, as well as the first documentation of thrips diversity and their association with spontaneous vegetation in peanut fields in the province of Córdoba.
Integrating edge computing with advanced cloud computing: A paradigm shift for IoT applications
Authors: Purushotham Reddy
Published: October 2024

In this paper we explore the coupling of edge computing with the superset advanced cloud computing and its applicability to the area of the Internet of Things (IoT), and we explore a paradigm shift in how data is processed and managed by connected devices. We prove experimentally that we achieve significant reductions in latency (86% on average), bandwidth optimization (58% data reduction on average), and energy efficiency (67% decrease in transmission related power consumption) through extensive experimentation and analysis. With the proposed integrated architecture, we show that we can scale up with minimal cost: we can accommodate a 500% increase in the number of connected devices while only incurring a 35% increase in cloud infrastructure. There are challenges in security, standardization and ultra-scale deployment. In this thesis we show that edge-cloud integration provides substantially higher benefits over conventional cloud-only and cloud-edge integration methods for most of the IoT scenarios investigated in this thesis, but adds new complexities that remain unexplored and need further research and development. These results in contribute to the developing framework of the IoT infrastructures, informing researchers and practitioners designing large scale, distributed systems, often with centralized control.

Psoriatic arthritis (PsA) accounts for around 20% of referrals to the early arthritis clinic and presents a significant diagnostic and management challenge. Early diagnosis is important to prevent long term functional disability and to ensure optimal management of arthritis and key comorbidities. From the rheumatologist’s perspective, the differential diagnosis includes rheumatoid arthritis, gout and other inflammatory arthritis’s. Once diagnosed, it is essential to assess the disease fully, including arthritis, enthesitis, dactylitis, skin/nail disease and axial involvement. Using this information, appropriate treatment can be planned using therapies that are effective at treating the relevant domains of disease. Despite poor data, traditional disease-modifying anti-rheumatic drugs are commonly used and have been effective in observational studies. Following tumour necrosis factor inhibitors, which have proven excellent efficacy in multiple domains of PsA, new biologics are available or in development and will improve treatment options for people with refractory PsA

In the environs of Tbilisi (Georgia, South Caucasus), 57 species of wildly grown trees and shrubs used for food by the local population have been identified. Five species of them are naturalized plants for Tbilisi area. The usage of edible trees and shrubs for food is diverse. Their different parts are used for food purposes - fruits, flowers, leaves, shoots. Moreover, the same species is used in different ways. It should be noted that the use of wildly grown trees and shrubs for food has decreased a lot in the last period. The main reasons for this are: (1) the population of Tbilisi and its surroundings mostly buys products in agricultural markets and supermarkets, (2) the rural population also grows various fruits in their homesteads, (3) a large part of the city population does not know about the use of various edible trees and shrubs.

Published: October 2024

This research explores the critical role of girls' education in alleviating poverty in Sokoto State, Nigeria. It highlights the significant gender disparities in educational access, driven by cultural norms that prioritize boys' education, which impede both individual potential and broader economic growth. The research underscores that educated women contribute to workforce participation and family income, thereby fostering community development and reducing poverty. Despite some progress, challenges such as socio-cultural attitudes, inadequate infrastructure, and economic constraints persist, necessitating a multi-faceted approach involving policy reforms and community engagement. The study employs a mixed-methods methodology, revealing that while enrolment rates have improved, gender inequities remain pronounced. It advocates for targeted interventions and community involvement to shift perceptions and enhance girls' educational opportunities, ultimately aiming for sustainable development goals in Northern Nigeria.

Today, women’s health is a separate issue for doctors of many specialties, including obstetricians and gynecologists, family doctors, etc. There is a wide range of treatment options for managing diseases of the reproductive system in women. But despite this, many of these strategies do not work for our patients. Therefore, we need the latest personalized approaches to therapy. One of the newest trends in women’s health is the correction or restoration of the vaginal microbiome. In our previous publications, we have covered the issue of the normal composition of the vaginal microbiome and its changes in various pathological conditions. Modification of the vaginal microbiome can be a useful strategy in the treatment of sexually transmitted infections, bacterial vaginosis, candidiasis, benign, precancerous and even malignant diseases of the female reproductive system, miscarriage, preterm birth and other pregnancy complications.The concept of using exogenous microorganisms as a treatment has been known for centuries. Possible mechanisms by which exogenous strains of lactobacilli can affect vaginal microbiome include vaginal recolonization, increased production or release of lactic acid and other antimicrobial compounds, and modulation of the local mucosal immune response. From a microbiome perspective, “prebiotics” are nutraceutical compounds that induce bacterial growth or the activity of probiotics or beneficial endogenous microorganisms. One of the limitations of prebiotics is their dependence on the presence of lactobacilli, which are absent or almost absent in dysbiosis. Symbiotics are combinations of prebiotics and probiotics based on the concept that the first nutraceutical can improve the bacterial growth and function of the other. This review highlights the latest views on correction and/or restoration of the vaginal microbiome using not only probiotics, prebiotics, and symbiotic, but also phage-altering agents, phage therapy, vaginal microbiome transplantation, etc. Such methods of correction and/or restoration are currently relevant in the reproductive medicine, gynecology and obstetrics all over the world. Despite the fact that these are the newest methods of correction and/or restoration, they are developing every day and require more detailed coverage of this issue.

The high prevalence of endometriosis, its impact on menstrual and reproductive functions, obstetric complications, and the quality of life of women in the reproductive age determines the urgency of the problem.The objective: to assess the prevalence of inflammatory changes in foci of heterotopic endometrium in patients with endometriosis and adenomyosis.Materials and methods. 92 women of reproductive age – from 21 to 46 years old – who applied for surgical treatment for symptomatic adenomyosis (47 women – 1st group) and ovarian endometriosis (45 patients – 2nd group), and 30 practically healthy women of the same age (control group) were examined.Histological examination of adenomyosis and ovarian endometriosis biopsies was performed using a light microscope at magnifications of 40 and 100. For immunohistochemical examination, primary and secondary antibodies were used to determine CD34, CD68, and CD138 markers.Results. In patients with adenomyosis and ovarian endometriosis the following concomitant gynecological pathologies as uterine fibroids, endometrial hyperplasia, chronic endometritis, chronic abnormal uterine bleeding, the frequency of which is significantly higher in adenomyosis, were diagnosed. This may indicate the pathogenetic role of chronic inflammation in the development of these pathological conditions.In patients with adenomyosis the positive expression of CD68 in the epithelial component of heterotopias was determined in 8 (17.0±5.6%) women, and in 4 (8.9±4.2%) women with ovarian endometriosis, which indicated a low phagocytic activity. During the assessment of CD34 expression in vessel walls and the stromal component of endometrioid heterotopias, a positive reaction was determined in 16 (34.0±6.9%) patients with adenomyosis and in 10 (22.2±6.2%) patients with ovarian endometriosis, which reflects the processes of neoangiogenesis and the activity of the pathological process.Positive expression of CD138 in endometrioid heterotopias prevailed in the group of patients with adenomyosis – 12 (25.5±6.4%) cases versus 4 (8.9±4.2%) cases in the group of patients with ovarian endometriosis (p<0.05). This confirmed the histological results and clinical data regarding the presence of chronic endometritis and isthmocele.Conclusions. The identified inflammatory changes, weak phagocytic activity and signs of neoangiogenesis in foci of heterotopic endometrium are more significant in patients with adenomyosis, which is confirmed by clinical and morphological data.

Ensuring the integrity of halal food is among the concerned issues of many Muslim consumers around the world especially on the authenticity of halal food products status. They are keen to know all the activities involved whether the products they purchase are genuinely halal along the supply chain. Although the issue of halal integrity is widely discussed within the halal food industry, the factors attract the attention of both the academic and halal practitioners remain ambiguous. Thus, this paper intends to assess the existing halal food supply chain management (HFSCM) and its influence on halal integrity assurance (HIA). Using quantitative approach, an industry pilots were empirically experimented to test the concepts and provide practical solutions for halal industry players to optimize their HIA in food and beverages (F&B) industries. The survey data was acquired from 121 halal F&B industries. Multiple linear regression technique was used to analyze the data. It was found that the HFSCM of F&B industries have a direct impact on HIA. The findings are set out to argue that new solutions are required to reduce the vulnerability for better optimization of HFSCM thus enhancing the HIA. Significantly, this study seen Technical and Vocational Education and Training (TVET) is critical in ensuring the sustainability of HFSCMspecially to cater demands among Muslim population.
