Ефективним напрямком підвищення безвідмовності, та вцілому й надійності підшипникових вузлів кривошипно-шатунного механізму (КШМ) є розробка нових та вдосконалення існуючих методів діагностування їх працездатності та працездатності систем змащування (СЗ) без виведення двигунів з дії. Особливо це актуально для головних суднових двигунів внутрішнього згоряння (ДВЗ), що функціонують в умовах тривалої безперервної дії на різних режимах навантаження. На практиці застосовуються непрямі методи оцінки працездатності підшипників КШМ шляхом моніторингу показників функціональних параметрів: температури оливи на вході та виході з підшипників, концентрації парів оливи в картері дизеля та ін. Додатково працездатність СЗ оцінюється моніторингом тиску оливи на вході в двигун, та виконується періодичний контроль її в’язкості, що є основним показником, який забезпечує працездатність підшипників ковзання. При пошуку алгоритмів діагностування СЗ виділено два контури діагностування: контур подачі, очищення та охолодження моторної оливи й контур змащування підшипникових вузлів та охолодження поршнів. Перед проведенням аналізу кореляційних зв’язків між діагностичними параметрами виділено основні несправності: забруднення сітки оливоприймача, знос деталей насосу оливи, заклинювання золотника запобіжного клапану, інтенсивне забруднення фільтра оливи, відхилення в’язкості моторної оливи від встановленого діапазону заводом-виробником. Для визначення характеристик елементів СЗ проведено ряд експериментальних стендових досліджень при різних умовах її функціонування: при відсутності відхилень робочихпараметрів від нормативних; при підвищеній витраті моторної оливи через головну оливну магістраль; при підвищеному значенні опору на лінії всмоктування моторної оливи; при підвищеному значенні опору фільтру оливи (експлуатація дизеля із фільтром оливи, щомає значне забруднення фільтруючого елементу); при фіксованому відкритому положенні золотника запобіжного клапану. Наведені результати вказують на недостатність існуючих засобів діагностування працездатності елементів СЗ, а також відсутність можливостей забезпечення необхідної повноти діагностування навіть при можливості додаткового вимірювання тиску безпосередньо в контурі системи подачі, очищення та охолодження моторної оливи. Внаслідок впливу запобіжного клапану на показники тиску як в контурі, так і в напірній магістралі, компенсувати відсутність діагностичної інформації можливо шляхом визначення витрати моторної оливи через запобіжний клапан.Ключові слова: високообертовий двигун внутрішнього згоряння, система змащування, фільтр оливи, насос оливи, запобіжний клапан

Розглянуті методи контролю та управління рухом морських суден під час маневрування з метою забезпечення їх безпечного розходження за умовою хорошої видимості. Для вирішення питання щодо забезпечення безпеки судноплавства були розглянуті підмножини ситуаційнадмірного зближення суден з різною взаємною відповідальністю та з різним розташуванням суден один від одного, що регламентуються відповідними вимогами Міжнародних правил запобігання зіткнення суден у морі які встановлюють взаємодію суден залежно від ситуації, що виникла під час небезпечного зближення. Визначено, що процес розходження двох суден передбачає зміну ситуації небезпечного зближення на допустиму безпечну ситуацію за допомогою маневру розходження. Вказано, що для забезпечення процесу безпечного розходження важливою складовою є управління ситуацією зближення, за допомогою якого визначається потенційна можливість зміни небезпечної ситуації шляхом виконання маневру розходження. Також зазначено, що через велику кількість різноманітних ситуацій у взаємних розташуваннях суден, виникають певні труднощі в коректності дій, що приймаються з метою забезпечення їх безпечного розходження. Тому питання формалізації процесу розробки методів управління рухом судна, у частині маневрування суден під час розходження, а також визначення методу управління рухом суден морського транспорту під час забезпечення їх безпечного розходження є актуальним та перспективним науковим напрямом яке впливає на безпеку судноплавства.Як основні небезпечні ситуації, що виникають під час розходження суден, розглянути ситуація обгону (відносно варіантів судно, що обганяє, та судно, що обганяється; а також судно, що обганяється, та судно, що обганяє), ситуація зближення суден на зустрічних курсах, ситуація зближення суден на курсах, що перетинаються. Для кожної з цих ситуацій запропоновані аналітичні залежності з визначення небезпечних курсів руху суден, які попереджують їх зіткнення. Запропоновані рішення сприяють створенню методу управління рухом суден під час виникнення різних ситуаціях їх небезпечного зближення .Отримані результати свідчать про можливість застосування розроблених аналітичних виразів в сучасних електронних автоматичних системах, що працюють за принципом реального часу з метою визначення та розв’язання завдань на розходження, які є суттєвою підтримкою для навігаційних офіцерів під час виникнення ситуацій небезпечного зближення суден.

Published: February 2024

At present, as energy resources are increasingly scarce, it is necessary to apply a highly efficient savings policy. In this context, it is essential to study and analyze electrical systems, mainly supply systems in production and service facilities. It is important to point out that in peak electricity hours, even the least efficient generating machines have to work, increasing oil consumption per kWh generated; on the other hand, there are great difficulties in transferring power from different generating units to the places where electricity is consumed in those critical hours. Therefore, when the energy demand is not in correspondence with the generation of the generating plants, it is then necessary to interrupt some loads, producing the well-known blackouts and, consequently, the inconvenience and affectations of the users of the electrical service, it is in these cases where the need for electric charge accommodation becomes evident. Therefore, this article aims to propose an application to accommodate loads in industrial systems, through a graphical interface, based on the free software Scilab, which among other things allows load accommodation considering the installation or not of a photovoltaic system. To verify its usefulness, the UEB Pinturas Vitral located in the municipality of San José de las Lajas, Mayabeque Province, Cuba, has 2 work shifts.

Published: February 2024

Este artículo presenta el desarrollo de una herramienta de cálculo de los residuos de los modos críticos de oscilación para un sistema eléctrico, utilizando datos del análisis modal de PowerFactory de DIgSILENT. El problema planteado es de gran importancia en los sistemas eléctricos actuales, los cuales se caracterizan por operar sus elementos al límite y si estas oscilaciones, no son adecuadamente amortiguadas, pueden causar fallas en la generación al reducir el nivel de estabilidad del sistema. PowerFactory es una herramienta de ingeniería para analizar sistemas eléctricos, utilizado ampliamente en la industria e investigación. Este software cuenta con un lenguaje propio de programación, a saber, DIgSILENT Programming Language (DPL), el cual permite procesar variables de interés desde el análisis modal, mismas que pueden ser usadas en otros dispositivos del sistema, como son los estabilizadores de sistemas de potencia (PSS). Mediante programación de las variables de interés, se calcula el residuo de los modos críticos de oscilación. Así, el cálculo del residuo requiere del procesamiento de la matriz de estados A facilitada directamente por PowerFactory y de la construcción de las matrices de las variables de entrada B y salida C, respectivamente, por medio de programación DPL para diferentes escenarios operativos del sistema eléctrico de potencia. La metodología de cálculo se ha aplicado a sistemas eléctricos disponibles en la literatura especializada en estabilidad oscilatoria en la cual se aplica la herramienta para observar la dinámica de los modos de oscilación con y sin PSS, siendo estos últimos sintonizados mediante el residuo calculado.

Published: February 2024

This work described a simple and sensitive spectrophotometric procedure for estimating phenylephrine hydrochloride in pure and in its pharmaceutical using diazotized sulphanilic acid as a coupling agent in alkaline medium of sodium carbonate solution. The resulting yellow azo-dye displayed an absorption maximum at 441 nm. The calibration graph was linear and compatible to Beer's law over the concentration range 0.2-20 µg/mL with coefficient estimated (r2=0.9996). The values of molar absorptivity and the sensitivity of Sandell's index were calculated and equal to 8.51×103 l/mol.cm and0.0239 µg/cm2, respectively. The values of detection limit (LOD), quantification limit (LOQ) and the range of relative error percentage were estimated and found to be 0.0050, 0.0166 µg/mL and -0.374% to -0.147%, respectively. The precision (represented by RSD) was also calculated and found to be in the range ±0.037 to ±0.28. The suggested procedure was useful successfully to the assay of phenylephrine hydrochloride in injection, drops and syrups. No interferences were observed from common additives found in pharmaceutical preparations. The yellow color of the product was highly stable and did not show a significant change in absorbance up to 60 min

Deploying AMT for Scale Versus Scope: A Contingency Approach
Authors: Sawhney Rajeev , Sumukadas Narendar
Published: February 2024

Flexibility and efficiency are twin capabilities of advanced manufacturing technologies (AMT). Much research has focused on AMT’s role in bolstering manufacturing flexibility. Meanwhile, AMT’s potential for efficiency is often disregarded, even proscribed by researchers, because that dampens the effect on flexibility. Yet, research shows that practitioners frequently implement AMT to pursue efficiency over flexibility. This problem has not been addressed in the literature. We approach this problem by viewing AMT through a strategic lens and examining AMT at the deployment level. Firms with different strategic goals must deploy AMT differently due to flexibility and efficiency often being opposite ends of a tradeoff. We identify two modes of deployment – AMTScale versus AMTScope – with characteristically different features, which explains AMT’s ability to support opposed strategies. Our unique conceptualization puts into proper perspective the mixed empirical results reported in the literature. Drawing on the contingency theory, we find that firms deploying AMTScope (to support a ‘differentiation’ strategy) derive flexibility, while firms deploying AMTScale (to support a ‘cost-leadership’ strategy) sacrifice flexibility.

Published: February 2024

Background and aims: This study investigated the effects of gonadal removal in male and female rats on changes in serum biochemical parameters. Methods: Twenty-eight adult male and female rats were divided into four groups of 7 animals for a period of 9 weeks. The first and second groups of intact male and female rats, as well as the third and fourth groups of male and female rats, were gonadectomized, respectively. At the end of the ninth week of the study, the rats were anesthetized with chloroform, and the amount of glucose, some lipid parameters in serum, and the activity of a number of serum enzymes were measured after taking blood from the heart. Results: Alanine aminotransferase, and alkaline phosphatase (ALP) levels were higher in intact male rats than in intact female rats, respectively (P=0.03, P=0.015). The amounts of glucose and cholesterol of low-density lipoprotein (LDL) in intact female rats were higher than in the ovariectomized rats, respectively (P=0.07, P=0.039, P=0.03). The amount of lactate dehydrogenase (LDH) in spayed female rats demonstrated a significant increase compared to other groups (P=0.001). However, there was a significant decrease in calcium levels in gonadectomized rat groups in comparison to intact female rats (P=0.02). Finally, a significant increase was found in phosphorous levels in the intact male rats group compared to other groups (P=0.002). Conclusion: Decreased sex hormones in gonadectomized rats compared with intact rats could lead to increased serum levels of LDH, ALP, and LDL cholesterol that may result in the development of metabolic and atherogenesis syndromes and acute liver failure.

The Global Covid-19 Pandemic
Authors: Nyere Chidochashe
Published: February 2024

The politics of science, or better still, the political science of global politics is what the world is battling, concerning the Coronavirus (Covid-19) pandemic, today. Whereas scientific disciplines such as virology and epidemiology would usually take centre stage when an outbreak such as Covid-19 strikes, and now owing to the vacuum that has been created by conflicting and contradictory information from health experts on Covid-19, global health is opened up to, or left up to, political giants. Health matters of virology and epidemiology surrounding Covid-19 have, thus, been reduced to issues of politicking. The World Health Organisation's voice (WHO), despite its sustained campaign and provision of information on Covid-19, is drowned and almost silenced by the number of health authorities and experts that have come out to refute mainstream information and strategies on combating and managing Covid-19. As such, the politicization of Covid-19 and the coloniality of knowledge and information surrounding Covid-19 may very well be the main issue of contention than the Covid-19 itself. This paper, therefore, seeks to unmask the political dimensions that are camouflaged by the Covid-19 pandemic and expose the real issues that Covid-19 has allowed to thrive and are, as a result, sustained by the Covid-19 crisis. Using the qualitative research methodology, I set out to discuss and analyse the debates on Covid-19 as have been proffered in the public domain. Thus, the method of research is a desktop analysis of academic articles, newspaper articles, social media pieces and mainstream television pieces, among others. I offer a decolonial account on Covid-19.
The New Apartheid

The fundamental distinction between a Civil Rights movement such as the African National Congress and a liberation movement like Poqo lies in the status of white settlers and Apartheid. The mythologisation of Apartheid by promoting it to the main problem in liberation politics and history in conqueror South Africa  is the persistent intellectual obsession of the Congress Tradition. A trenchant contestation and rejection of Apartheid as the fundamental antagonism in the history of the struggle for national liberation is the defining trait of a liberation movement and liberation intellectual production.Having written a book entitled Democracy & Delusion: 10 Myths (2019), in which he debunks what he considers to be myths about the so-called post-Apartheid South Africa, Sizwe is back again only this time he is reinventing two myths.In the book under review, entitled The New Apartheid (2021), Sizwe promotes the delusion and first myth of Apartheid as the problem and the second myth of the ANC as a liberation movement. This review is about these two myths.
