The Yannoe Force in the Mechanics of “Aspin Bubbles”
Authors:   Doctor in Physics, University of Zaragoza, Spain, Lana-Renault Yoël
Published: October 2024

"Aspin Bubbles" is a theory that obtains all known forces (electric, gravity, nuclear, Casimir...) based on a single mechanical interaction between waves and particles that make up our matter. The most surprising thing is that it demonstrates that the force of the gravity is a consequence of the sum of all the electrical forces existing between two neutral materials. In addition, "Aspin Bubbles" opens the door to new knowledge with the obtaining of a force not yet detected that it calls "Yannoe force", and with it, explains phenomena such as the levitation of clouds, dark matter, dark energy and the accelerated expansion of our universe
Revisiting the Matter of Time Dilation in Special Relativity
Authors:   Department of Mechanical and Aerospace Engineering, University of Strathclyde, 75 Montrose St Glasgow, G1 1XQ , UK, McKelvie James
Published: October 2024

There are different interpretations of the Lorentz transformations of the Special Theory of Relativity (SR) concerning the relative rates of two clocks that are moving at constant relative rectilinear velocity (Einstein’s definition of conditions necessary for SR). [It is common to talk in terms of how one observer “views” another clock that is moving at constant velocity relative to them. This carries an implication of visual observation. That is a limitation avoided in this contribution by the use of “as determined”, without specifying the means employed, but wherever “as viewed” does occur, it is to be considered as “as determined”]. One opinion, which is the settled opinion among physicists, holds that the clocks are “actually” going at different rates. Another opinion holds that it is merely a matter of how observers determine the clocks’ rates to be related, with the clocks in fact going at the same rate. The differences in these interpretations are resolved analytically. Five arguments are presented [excluding an inference from the first postulate]. The clocks are determined to have the same rates, i.e. there is no “time dilation” under SR conditions. The related opinion – that the clocks are going at the same rate, but are determined by observers to be going at different rates - is seen to be consistent. Experimental reports, which directly conclude that the clocks are going at different rates, are shown to be seriously flawed, or to not even comply with Einstein’s definition of SR
Ether Gravity
Authors:   Independent Researcher, Laguna Woods, California, United States, Olah Steve
Published: October 2024

Mass does not create Gravity. Ether Energy Flow is Gravity. Ether fills the Universe and ether envelopes the Sun. High energy ether transfers some of its energy to the Sun, creating an energy density gradient in ether. The resulting Ether Energy River flows from the far corners of the Universe into the Sun. It is a “surround” river like a globe. This ether energy flow is Gravity. It is pushing the Planets, including our Earth toward the Sun. In addition, the Energy carried by this River of ether to the Sun causes the Sun to heat up and glow. The Sun and every celestial body is powered from the outside by Ether’s Energy. This ether energy river also caused the Pioneer Anomaly.
The 4-Dimensional Spacetime World Line Image Representation and the Law of Existence of Objects Inferred from it
Authors:   Retired from California State, 1620 Norvell Street, El Cerrito, CA, USA, Wu Yuxiang
Published: October 2024

MINKOWSKI defined the four-dimensional spacetime model (x, y, z, t) used to represent world-point and world in [1]. The spacetime light cone is an intuitive diagram, compacted one space component and replaced it by time axis, thus the spacetime light cone was based on (x, y, t). In such a way, although it made the visual expression is possible, but also the spacetime light cone exposed shortages as follows • The spacetime light cone has limited expressive ability • The relationship between two or more world lines or events cannot be expressed • Can't express different world lines correctly • Most images of spacetime light cones are wrong and no use • The image of spacetime light cone is not intuitive and is obscure in application. Because of this, we designed the 4-dimensional Spacetime World Line image representation. This new 4-dimensional Spacetime diagram presents the complete 3 space dimensions and 1 time dimension. It overcomes the weakness of spacetime light cone, gives clear and precise visual expression of the world line, is able to display multi-world lines in one figure, can clearly present the interface and development process of each of the world line, and display the interaction among them. From the 4-dimensional spacetime diagram, we deducted and proved the Law of Existence of Object, which is as such: From its birth, through its past, to the present, and into the future, an object only exists at the "present" moment.

Published: October 2024

This study investigated community health awareness and health education on diphtheria among residents of a local government area in Edo State. Two research questions and two hypotheses were formulated for the study. The population comprised 117,209 from which a sample of 399 was selected by means of cross sectional descriptive research design. Data collection was by means of a structured questionnaire and analyzed using descriptive and inferential statistics with hypotheses tested at 0.05 level of significance. Reliability coefficients of 0.84 and 0.79 were obtained for awareness and health education respectively. Results revealed low awareness on diphtheria among majority (93.5%), 24.1% had moderate awareness, 2.0% had high awareness. 93.5% claimed there had never been community awareness campaign on diphtheria in their community, 85.7% reported never to have attended seminar/health talks on diphtheria infection. Level of education on diphtheria was low (21.2%). Majority of the respondents (61.4%) had low level of education on diphtheria. Gender and educational background were significantly associated with community health awareness on diphtheria (p = .000). The study recommends that since the level of health awareness and education was low among the population, nursing practitioners should consider community health awareness campaign on diphtheria in communities in other to raise awareness. Females and those with low educational background, should be targeted to ensure they seek information on diphtheria to protect their health.

Effect of School Leadership on Academic Performance of Public Senior High Schools in Ghana
Authors: Afram Kwame Owusu-Ansah Owusu , Okeyo Washington , Kwarteng Charles Owusu
Published: October 2024

Since gaining independence, Ghana has implemented several reforms to enhance secondary education. However, these reforms have yet to fully achieve their intended improvements in the academic performance of second-cycle schools. According to the Ghana Education Service and the Ministry of Education, while pass rates in core subjects have improved from 2006 to 2021, performance in the core subjects still falls short of 40%. This persistent underperformance has been attributed to school leadership and their capacity to effectively implement a vision for enhancing teachers’ skills and knowledge. The purpose of this study was to examine the effect of school leadership on academic performance of public senior high schools in Ghana. The study examined the instructional and supervisory functions of school leadership. The study was anchored on distributed leadership and social learning theories. The study employed a positivist approach to systematically explore the relationship between the variables. The target population of the study was the 928 public senior high schools listed by the Ghana Education Service as of December 2023. The study applied the cross-sectional design survey and cluster-stratified random sample to collect data from 2176 respondents. The primary data was analyzed using both descriptive and inferential statistics. The results revealed that there was a significant positive correlation (R= 0.669) between school leadership and academic performance of public senior high schools in Ghana. The study may be limited due to the use of the cross-sectional design survey, which cannot determine cause-and-effect relationships as data were collected at one point in time. The study recommends that school leadership should be prioritised in senior high schools in Ghana to facilitate the achievement of academic performance improvements in the schools. The Ministry and Ghana Education Service must ensure the appointment of competent school leadership to the senior high schools. Stakeholders of senior high school education in Ghana must equip school leadership for the performance of their roles. School leadership must adopt interventions to give teachers professional development to be effective in their teaching and learning methods.
Health Risks of Climate Change and Variability to Maternal Health
Authors: Mashara Janet Naisoi , Thuranira Mercy , Kathambi Fridah
Published: October 2024

Climate change has emerged as a significant global challenge with far-reaching implications to human health. Through a comprehensive review of scholarly articles, the study examines the complex interplay between climate change and maternal health and highlights the role of religion in climate change mitigation. Mothers play an integral role in creating and sustaining healthy households. Furthermore, improving maternal health is essential to achieving global sustainable development goals, particularly goal 3 (Good Health and Well-being). The paper sought to examine the physical and psychosocial effects of climate change on expectant mothers. The study explored the following objectives: the direct impacts of climate change on maternal health; Indirect impacts of climate change on maternal; and mitigation strategies. The study revealed that, rising temperatures and heatwaves increase maternal heat-related illnesses, potentially affecting birth outcomes. Vector-borne diseases, influenced by climate shifts, pose additional threats to maternal well-being. Environmental stressors, including natural disasters and climate-related migration, contribute to maternal stress, anxiety and depression affecting maternal care. Christian teachings acknowledge human life as precious and sacred. It should be protected and valued from conception until death. Religious beliefs and values lay emphasis on stewardship of the environment, social justice, compassion, and community support. Religious institutions and leaders can play pivotal roles in advocating for climate action, promoting sustainable practices, and providing psychosocial support to individuals and families affected by climate-related health issues. To effectively combat climate change effects, the study recommends that it is imperative to embrace integrated approaches that prioritize healthcare access, environmental resilience, mental health support, and community-based initiatives that integrate religious perspectives with scientific knowledge and best practices.
Myths and Inclusive Education of Children with Disabilities in Universities of Uganda
Authors: Vincent. Kayindu , Sophia Kazibwe
Published: October 2024

The current study was carried out in five universities of Uganda to assess the influence of myths on the inclusive education of children with disabilities in universities of Uganda. The quantitative data were collected from 95 lecturers, while qualitative data was collected from ten university students. The study found out that although the government has put in place several mechanisms to promote the education of disabled children, and although the government, civic leaders, religious leaders and non government organisations have done much to educate parents that disabled children are as important as those who are not disabled and should therefore be taken to school, many parents still hold negative stereotypes about children with disabilities. Their inclusive education is poor as regards enrolment in universities, and their interaction with other students is limited. However, their performance in academics is almost the same as that of the other normal students. The study un-covered that although universities are competing for students, many of them do not have conducive environment for students with disabilities. Secondly, the myths of the people in Uganda point to lack of appreciating children with disabilities as they are seen as a punishment and a curse from God, the ancestors and witchcraft. Therefore, myths have a significant influence on the poor inclusive education of children with disabilities in the universities of Uganda. Therefore, there is need for the government, religious leaders, teachers and civic leaders to educate the masses more on the value of educating children with disabilitiesup to university level since these children are useful to the country and to their families just as those without disabilities are.

In an environment characterized by complexity and the need for collaboration, the ability to convey information clearly and efficiently is paramount in achieving project goals. This paper examines the significance of good communication in fostering the development of knowledge and skills among project team members. By facilitating productive information exchange, effective communication empowers team members to collaboratively solve problems and work together more efficiently. This, in turn, leads to a collective understanding of the project and accelerates decision-making processes while improving the overall quality of project outcomes. Through various case studies and analyses, this paper also outlines best practices for communication within construction project teams that can contribute to the growth of team members’ knowledge and skills. Ultimately, the findings suggest that effective communication not only strengthens interpersonal relationships among team members but also significantly enhances the overall performance of construction projects.
Dempster Combination Rule-Aided Multi-Sensor Decision-Level-Based Data Fusion in Industrial Internet of Things (IIoT) over Zero-Trust Security
Authors: Singh Anamika , Kumar Dhanaraj Rajesh , Kumar Sharma Anupam
Published: October 2024

Data fusion is a process of accommodating data from discrete sources to generate more relevant information with enhanced accuracy and compatibility rather than the data gathered and information produced by the identical or particular source. To achieve better accuracy in the information inferred by the Industrial Internet of Things (IIoT) system, data fusion is an emerging technology that takes data from different involved devices as input and generates more consistent and accurate information. To safeguard the IIoT data involved in communication foremost is to ensure the authenticity of the devices to block unauthorized access and thus enhance the data confidentiality and data integrity as well. Zero-trust security is thus employed in the IIoT infrastructure to meet the security requirements in question. The proposed approach, Dempster combination rule-aided multi-sensor decision-level-based data fusion (MS-DLDF) in Industrial Internet of Things (IIoT) over zero-trust security, breaks down the whole concept into phases – initially, the device authenticity is ensured before entering and accessing the network, next, the device data is then encoded to avoid data theft or breach from any unauthorized device, and lastly, the data fusion algorithm is executed to gather data from multiple sources as input and reach to more appropriate and relevant information as compared to the information inferred from a single source. The proposed MS-DLDF concludes with the outstanding results of the Dempster combination rule with the increased number of sensors in complex networks as compared to the single-source data fusion and Bayesian estimation data fusion with enhanced accuracy by 6%, minimal computation time by 15%, increased precision rate 6%, reduced false positive rate by 31%, and the amplified data confidentiality rate by 2%, respectively.

Authors: B. K. Smailova  , T. M. Buzauova  , I. A. Bartenev  , J. Škamat
Published: October 2024

This study examines the quality of a gear tooth surface fragment restored through electric arc welding. Visual inspection revealed a defect-free, dense surface. Macrostructure examination displayed uniformity and absence of cracks in the metal sample. The high hardness (HRC-36.61) of the weld deposit is crucial for wear resistance, while the base metal, with lower hardness (HRC-29.09), ensures ductility and impact toughness. Martensitic and residual austenitic structures in the weld deposit indicate deformation-resistant properties, with austenite providing good ductility and martensite contributing to high hardness and strength, making the material resistant to wear and deformation under dynamic loads. Thin lens-like martensitic plates and a reed-like structure suggest unique formation characteristics during electroslag welding’s oxidizing-reducing reactions. Microstructure analysis revealed a finer structure in the weld deposit compared to the base metal. The base metal exhibited a ferrite-pearlite structure typical of many steels, unchanged after welding. The weld deposit showed elevated carbon (0.70 %) and manganese (1.38 %) concentrations, typical for weld deposits, influencing mechanical properties. Elements like manganese and molybdenum enhance wear resistance, while the presence of chromium (0.42 %) and nickel (0.12 %) improves corrosion resistance, crucial in aggressive environments. Keywords: large-module gears, tooth wear, electro slag surfacing, hardness, analysis

STUDY OF THE SEAMLESS PIPES PROPERTIES OBTAINED FROM A HOLLOW BILLET
Authors: А. Т. Zhakupova
Published: October 2024

The article researched the influence on the pipes mechanical properties initial billet obtained by the traditional method and the proposed method, in which the piercing process is excluded. The proposed method involves casting the initial billet for the production of seamless pipes with a cavity obtained on a continuous casting machine. The production of hotrolled seamless pipes from a hollow billet is an urgent issue today, since central porosity and axial segregation after casting are excluded, affecting the quality of the pipes obtained in the subsequent stages of production: rolling on a mandrel mill and reducing. The possibility of producing seamless hot-rolled pipes from a hollow billet is substantiated, providing the necessary set of mechanical properties that are regulated by the standards GOST 632-80, GOST 633-80 and API 5CT. The result is a minimal deviation of the mechanical properties of steel samples obtained by double deformation of a hollow continuously cast billet from samples obtained according to the traditional scheme, including the piercing process. Keywords: hollow billet, steel, 09Mn2Si, seamless pipe, piercing process.

Бұл мақаланың мақсаты-ысқылап қалыптастыру әдісін қолдану арқылы саусақты фрезаның тозуға төзімділігін арттыру. Саусақтық фрезаны ысқылап қалыптастыру процесін эксперименттік зерттеуді жоспарлау үшін екінші ретті ротатабельді жоспарлау қолданылады. Саусақтық фрезаларды ысқылап қалыптастыру бойынша эксперименттік зерттеулер болат 45 материалынан дайындаманы фрезерлеу кезінде ХН950А тік-фрезерлеу станогында жүргізілді. Өңдеу режимдерін олардың белгілі бір мәндеріне дейін ұлғайту (s = 36 мм/мин; n = 80 айн/мин; t = 6 мин) құралдың тұрақтылық кезеңіне оң әсер ететіні анықталды. Бұл ретте құралдың тұрақтылық кезеңін t=142 минутқа дейін арттыруға қол жеткізілді. Саусақты фрезаның тұрақтылық кезеңін анықтау зертханалық база жағдайында орындалды. Алдын ала ысқылап қалыптастырудан кейін фрезаларды дайындама кесу арқылы жұмыс істеу ұзақтығы анықталды. Құралды ысқылап қалыптастырудың оңтайлы режимі құралдың кесу бөлігін беріктендіру үшін ең жақсы деформациялық-жылу жағдайларын қамтамасыз ететіні анықталды. ANSYS бағдарламасының көмегімен модельдеу нәтижесінде, шын мәнінде, өңдеуден кейін саусақтық фрезаның кесу бөлігінде қатайтылған қабат пайда болатындығы анықталды. Зерттеу жұмыстары АР14972884 «Ысқылап қалыптастыру әдісімен металл кескіш құралдардың тозуға төзімділігін арттыру» гранттық жоба аясында жасалынды.

В последние годы наблюдается активное увеличение доли электромобилей в транспортных парках во многих странах мира, что вызывает необходимость широкого внедрения соответствующей инфраструктуры для зарядки электромобилей. Развертывание электрозарядной инфраструктуры должно осуществляться в соответствии со стратегией, учитывающей территориальные возможности локализации инфраструктурных объектов, спрос и предложение по предоставлению зарядных услуг, поведения пользователей электромобилей. В статье рассмотрены различные модели нормирования электрозарядной инфраструктуры, которые позволяют определить потребность в объектах зарядки электромобилей. В соответствии с нормативной моделью потребность определяется в зависимости между количеством электромобилей и. количеством электрозарядных станций. В модели на основе энергобаланса определяются прогнозные данные распространения электромобилей для определенных регионов и далее расчетным путем устанавливается количество и распределение точек зарядки для конкретного года. При этом количество пунктов зарядки и электромобилей соотносятся друг с другом с использованием квот. В модели на основе параметров электромобилей потребность определяется в зависимости от средних значений пробега электромобиля на одном заряде, недельного пробега электромобиля, км и продолжительности одной зарядки. Результаты развития электрозарядной инфраструктуры представлены на примере города Алматы. Ключевые слова: электромобили, электрозарядные станции, инфраструктура, методы нормирования, прогноз развития.

В работе проведены укрупненно-лабораторные испытания и показаны результаты по высокотемпературной восстановительной плавке металлизированных окатышей, который представляет заключительную стадию разрабатываемой новой комплексной безотходной технологии переработки мелкодисперсных марганцевых отходов, получаемых от обогащения руды на Джездинском ГОКе. В работе акцент сделан на заключительной стадии технологии – получении ферросплавов, в частности ферромарганца, путем восстановления металлизированных окатышей в электропечи, минуя традиционные процессы науглероживания металла и образования чугуна. Установлены оптимальные технологические параметры процесса: скорость нагрева печи – 40 ºС/мин.; температура плавки – 1650 ºС; продолжительность плавки – 2 ч., которые обеспечивают получение высококачественного ферромарганца с низким содержанием углерода (1,25 %). Полученные результаты химического состава ферромарганца свидетельствуют о высоком качестве и показывают его востребованность для легирования стали. Установлено, что выход ферромарганца составил ~40 % от загрузки. При этом получен сплав высокого качества, % масс.: 38,5 Fe, 54,44 Mn, 1,25 С. На основании положительных результатов исследований сформулирована общая концепция и разработана технологическая схема новой высокоэффективной энергосберегающей технологии, направленной на переработку различного по типу и составу марганец-, хромсодержащего техногенного сырья с получением ферросплавов высокого качества.

Abstract

Objective
Health care providers (HCPs) may serve as facilitators or barriers to access. We explore the knowledge, attitudes and practices of HCPs in Jamaica to identify gaps which may lead to unmet contraceptive needs for adolescents.

Methods
A cross-sectional study design was utilized to collect data from urban-based HCPs through a self-administered questionnaire regarding knowledge of, attitudes towards and practices in adolescent contraception. Summative knowledge and attitude scores were generated. Descriptive and inferential statistical analyses were performed.

Results
One hundred and forty-four HCPs participated with a female predominance (n=127; 88.2%) and median (IQR) age of 36 (20) years old. HCPs mean (SD) knowledge score 1.95 (0.81) negatively correlated with age (r= -0.279; p<0.01) and length of time working as an HCP (r= -0.287; p<0.01). Pharmacy staff had lowest mean (SD) scores, 13.4 (4.48); p<0.05. Mean attitude score did not differ significantly by marital status or religion. As HCPs’ length of time in practice increased there was a decrease in the attitude scores (β= -0.380; p<0.05).

Conclusion
There is need for capacity-building of HCPs to deliver active contraceptive counselling and provide modern, effective, evidence-based contraceptive services to adolescents in Jamaica. Review and revision of guidelines, policies and laws governing delivery of sexual and reproductive health services is recommended.

Abstract

Objective
The objectives of this study were to determine specialty choices, influencing factors, and migration intent among medical students, and to compare this with current specialist practitioners in Trinidad and Tobago (TT).

Methods 
A Cross-sectional study using an online survey was conducted at the School of Medicine, Faculty of Medical Sciences, University of the West Indies, St Augustine Campus, TT. Descriptive statistics were presented for choice of specialty, its predictors, and comparisons with specialists in practice were done.

Results
Overall, 273 (response rate 21.36%) students responded with 73.6% females and an average age of 22.5(SD3.3) The ten most popular responses for specialty of first choice were unsure (9.5%), cardiothoracic surgery (8.7%), general paediatrics (8.7%), general surgery (7.5%), neurosurgery (7.5%), obstetrics and gynaecology (6.7%), cardiology (4.8%), emergency medicine (4.4%), family medicine (4.4%) and orthopaedics (4.4%). The top three factors influencing their choices were, general interest in the field (95.9%), job security (81.3%) and job availability (70.3%), Most respondents (72%) expressed intent to migrate to specialize. Compared to specialist practitioners, significantly more students aspired to do cardiothoracic surgery, neurosurgery, pediatric surgery, and cardiology, while significantly less students chose internal medicine, anaesthesia and critical care, and ophthalmology. (P< 0.05 for all)

Conclusion
A minority of students was uncertain about speciality choice, however most intended to migrate to specialize. A mismatch between student aspirations and current practice was also found. These findings warrant student sensitization to specialties for which there is a need and workplace planning, if we are to retain locally trained doctors.
