Published: October 2024

This study explores the effectiveness and challenges of implementing the Contextual Teaching and Learning (CTL) model in multicultural classrooms, particularly focusing on its impact on interpersonal skills development. The primary aim is to investigate how the CTL model enhances student engagement by connecting academic content to real-world contexts and to identify the barriers that impede its effective application. This research utilized a qualitative approach with a case study method to examine the application of the CTL (Contextual Teaching and Learning) model in building inclusive learning communities and fostering interpersonal skills in multicultural classrooms. The data collection techniques used in this study included interviews, observations, and document analysis. The findings indicate that while the CTL model significantly enhances student engagement and fosters the development of interpersonal skills, its implementation is fraught with challenges. Key obstacles include insufficient teacher training, misalignment with existing curriculum standards, limited resources, and institutional barriers such as rigid schedules and lack of administrative support. Despite these challenges, the research highlights the importance of sustained professional development and a supportive learning community to overcome these barriers. By addressing these issues, educators can better leverage the CTL model to create inclusive and effective learning environments. Overall, this study underscores the potential of the CTL model to transform teaching practices and improve student outcomes in multicultural settings. It calls for a concerted effort to provide the necessary support and resources for educators to implement the CTL model successfully, thereby enhancing educational experiences and fostering inclusive learning communities.

Authors: Panchenko O. B. , Melnyk V. I. , Zhovtun M. V.
Published: October 2024

The article presents the results of changes in available soil moisture in winter wheat crops in four short-rotation crop rotations. The research was carried out during 2012-2021 at the experimental field of the Belotserki National Agrarian University of the Kyiv region. The soil of the experimental field is a typical chernozem with a low humus content of average loamy humus in the 0–30 cm soil layer of 3,7–3,9 %. Four short-rotation crop rotations were studied (sunflower saturation 10 %); cereal grain (sunflower saturation 20 %); specialized seedbed (sunflower saturation 30 %); rowing (sunflower saturation 40 %).

It was established that the reserves of available moisture for the period of winter wheat sowing were the highest in the grain-row specialized crop rotation, where wheat was sown after buckwheat with 257,2 mm in the 0–150 cm layer, 78,5 mm in the 0–50 cm layer. In the crop rotation in the 0–150 cm layer, they were 204,3 mm, in the 0–50 cm and 50–100 cm layers 59,4 and 52.4 mm, which is 19,1 and 15.0 less than in the grain-row crop rotation mm.

During the crop rotation, the reserves of available moisture for the harvesting period were 1372 m3/ha, grain-rowing – 1154 m3/ha, specialized grain-rowing and row-rowing – 1327 and 928 m3/ha, which affected the total moisture consumption. The highest consumption of available moisture was observed during row crop rotation - 4029 m3/ha, while during crop rotation the available moisture reserves were 4032 m3/ha. The coefficient of moisture consumption was the highest in specialized and row-row crops – 97,8 and 90,7 m3/t, respectively, while for crop rotation – 70,7, grain-row crops – 85,2 m3, which was less than row crops by 5,5 and 20 m3/t.

Authors: Voitovyk M. , Zhovtun M.
Published: October 2024

The purpose of the research was to identify the influence of mineral and organo-mineral fertilization systems during the main cultivation on changes in the biological activity of the arable layer of chernozem typical in the soybean agrocenosis of the five-field grain-row rotation of the Forest Steppe of Ukraine. The research was conducted during 2016–2020 on a typical deep low-humus chernozem of the Belotserkiv National Scientific Research Field. Three tillage systems were studied: differentiated, shelf-less and shallow, and three fertilization systems: without the use of fertilizers, organo-mineral and mineral.

It was established that the highest biological activity of typical chernozem in soybean crops in May was recorded during shelf-less tillage. The most pronounced differentiation of the arable layer was observed during shallow tillage. The difference in the weight loss of the linen cloth in the upper and lower parts of one layer of typical chernozem was 2,7% for differentiated, 7,7% - shelf-less, and 8,5% - shallow tillage.

The release of carbon dioxide from the soil in soybean agrocenosis in May is significantly higher than shelf-less tillage by 5,8%, shallow tillage without tillage by 2,7% compared to differentiated tillage.

Under the mineral fertilization system, the release of CO2 by the soil increased by 16,7–18,8% compared to the option without the use of fertilizers.

Una revisión crítica de la sostenibilidad social en los marcos de la responsabilidad social corporativa y el valor compartido
Authors: Beltrán Virgüez Jesús Enrique , Sanes Orrego Aida
Published: October 2024

Introducción: El artículo desarrolla una revisión sistemática de la literatura complementada con un análisis hermenéutico crítico. Las preguntas de investigación se centraron en identificar los referentes de sostenibilidad social en el ámbito organizacional y los mecanismos utilizados para su evaluación, buscando determinar su solidez. Metodología: Utilizando la base de datos Scopus, se analizaron documentos desde 2019 hasta 2024, considerando la estructura epistemológica, la fundamentación teórica, las perspectivas desde la responsabilidad social y el valor compartido, y las herramientas de evaluación. Resultados: Se observó una tendencia hacia la aplicación práctica más que teórica de los conceptos y una disparidad en la robustez del pilar ambiental frente a los aspectos sociales y económicos de la sostenibilidad. Discusión: El enfoque crítico interpretó la sostenibilidad como un metarrelato de la modernidad, dominado por una visión objetiva y cientificista. Conclusiones: Se considera que la sostenibilidad social, la responsabilidad social y el valor compartido están integrados con el modelo económico actual, lo que limita su eficacia al no promover una reinterpretación de la relación con el mundo extractivista. Se invita a reflexionar sobre la unidireccionalidad de la sostenibilidad social y a considerar una perspectiva más inclusiva, involucrando a diferentes actores como determinantes y no solo como criterios de valoración.

Published: October 2024

В сучасних умовах конкуренції, формування позитивного іміджу підприємства стає ключовим фактором успіху в будь-якій галузі, зокрема, у сфері послуг. Позитивний імідж підприємства допомагає збільшити його конкурентоспроможність, залучити нових клієнтів та зберегти старих, підвищити рівень довіри до компанії та підвищити її доходи.
Формування іміджу підприємства сфери послуг є надзвичайно важливим елементом його успіху. Імідж підприємства визначається сприйняттям клієнтами його товарів та послуг, а також уявленням про компанію в цілому. Сфера послуг має свої особливості, оскільки вона вимагає безперервного взаємодії з клієнтами та постійного покращення якості послуг, щоб задовольняти їхні потреби та очікування. Створення іміджу - питання стратегічного планування діяльності компанії. Привабливий імідж фірми може працювати довгі роки і підтримувати підприємство у важких обставинах. Тому при формуванні іміджу слід спиратися (в основному) на ті поняття і матеріальні об'єкти, які асоціюються у споживачів з вічними цінностями життя. Імідж підприємства визначається сукупністю характеристик, що дають уявлення про його діяльність. Для іміджу важлива не сама характеристика, а те уявлення, яке можна створити про неї професійними засобами і яке забезпечить організації позитивний імідж.
Актуальність дослідження теми формування іміджу підприємств сфери послуг має практичну значущість, оскільки результати дослідження можуть бути використані підприємствами для покращення їхньої репутації та збільшення задоволеності клієнтів.
Крім того, важливим аспектом дослідження є аналіз тенденцій формування іміджу в сфері послуг, зокрема з урахуванням сучасних інтернет-технологій та соціальних мереж.
Також актуальним залишається визначення специфіки формування іміджу підприємств сфери послуг, з огляду на їх особливості, наприклад, індивідуальний підхід до кожного клієнта, якість та ефективність обслуговування, інноваційність та конкурентоспроможність.
У статті розкрито значення іміджу для підприємства, яке надає послуги, і його вплив на конкурентоспроможність та ефективність діяльності. Імідж підприємства виступає як один з інструментів досягнення стратегічних цілей організації, що торкаються основних сторін її діяльності та орієнтовані на перспективу.

В сучасних ринкових умовах процес діджиталізації є одним з визначальних факторів економічного зростання підприємств, та й усього суспільства в цілому. Зміни зовнішнього середовища, зокрема технологічні трансформації, посилення інформаційних процесів, формування нових запитів споживання, зумовлюють зростання діджиталізації в усьому світі. Цю статтю присвячено проблемі розвитку персоналу на виробничому підприємстві у стратегічній та поточній площині. Розглянуто роль стратегій розвитку персоналу у сучасних умовах господарювання, вплив діджиталізації на технології управління персоналом, навчання персоналу як напрямок розвитку персоналу в сучасних умовах.  Швидка трансформація таких технологій, економічні та соціальні умови та економіка знань вимагає перегляду важливих аспектів управління на рівні підприємства. Управління персоналом відіграє важливу роль у цифровій трансформації бізнесу, забезпечуючи єдність дій та залученість персоналу до впровадження змін, попередження опору, удосконалення корпоративної культури і високу якість людського капіталу. У той же час, змінюючись та розвиваючись завдяки цій же цифровізації, на основі впровадження новітніх HR-технологій, оптимізації HR-процесів. Доведено, що цифрова реальність змушує підприємства для свого розвитку покращувати цифровізацію роботи як всередині компанії, так і за її межами. Перспективні HR-менеджери повинні мати у своєму розпорядженні сучасні технології та вміти ними ефективно управляти. На них покладається побудова основних HR-процесів та ефективне управління ними. Перехід на роботу з персоналом в цифровому форматі включає в себе безліч варіантів взаємодії роботодавців з працівниками, платформ та інструментів для побудови гнучких організацій і створення робочих місць нового типу. Запропоновано стратегію розвитку персоналу та розроблено заходи щодо її реалізації, спрямовані на впровадження системи навчання та розвитку персоналу. Цифрова трансформація бізнесу впливає на управління персоналом, діджиталізація цього процесу відбувається також кількома способами: від етапів залучення та набору персоналу в управлінні талантами до автоматизації процесів управління персоналом та керування даними. При цьому ефективний процес цифрової трансформації управління персоналом на підприємстві передбачає врахування існуючих можливостей та загроз і вироблення на цій основі ефективної стратегії діджиталізації.
ADOPTION OF STRATEGIC DECISIONS AT THE ENTERPRISE
Authors: MAZORENKO Oksana , KAITANSKYI Ivan , BILLO Keita
Published: October 2024

The process of determining the best way to achieve goals and objectives is called strategic decision making. These are long-term goals and objectives, as well as strategic decision-making tools, that help describe the company's primary goals in order to achieve short-term goals with a broad mission. In the long run, the company gains clarity and consistency in achieving its goals.
Strategic decision-making is used in competitive companies to give the company a competitive advantage by changing its scale and the way the company manages its operations. The difference between strategic decision-making and other decision-making processes, such as administrative and operational decision-making, is that strategic decision-making is a long-term process that requires significant resources and is fraught with uncertainty. Administrative decisions are based on short-term goals. Unlike other decision-making processes, strategic decision-making considers the long-term future of the company.
Successful business managers do more than just make money and sell products. They not only perform day-to-day sales tasks, but also look at the big picture and make decisions that will lead the company to its desired goal. This is known as strategic decision making, and it occurs when decisions are made in line with the company's goals or mission. This type of decision-making directs the choices made, aligning them with the company's goals. This requires creative thinking as managers must consider future scenarios that may or may not occur. These scenarios will determine the direction of the company's development. Business strategy is a competitive advantage. Businesses need strategies to ensure that resources are allocated in the most efficient way. There has been much research on strategies and much literature outlining the importance of strategies for successful business management. The word "strategy" is probably one of the most used words in business and everyday life [26]. According to Schendel, there are many preparation strategies in the business world for almost every potential activity, from employee management strategies to knowledge management strategies. At first glance, we have the idea that strategy is something simple that refers to the use of resources to realize pre-planned goals. But in practice, strategies differ in terms of time, and its formulation and implementation cannot be perfect. When a firm earns earnings above the average for its industry, the firm is said to have a competitive advantage over its rivals.

The Epoxy-based composites with Size-Fractionated Waste Areca Sheath: An Experimental Investigation on the Macroscopic and Vibrational Properties
Authors: Varghese Lijo , Mohan Kumar G.C.
Published: October 2024

The use of Areca sheath in developing a newer composite material is proposed in this article. The Areca sheath particulates are extracted by pulverizing long sheaths into different sizes of particulates and are reinforced into the epoxy to process the composites. The study evaluated these composites' macroscopic and vibrational properties, revealing that those with coarse particulates demonstrated superior tensile and flexural strengths, impact strength, hardness, and natural frequency. Notably, the coarse epoxy composite with a 10% weight fraction of particulates exhibited tensile strength and modulus values of 24 MPa and 1050 MPa, respectively. These findings suggest that incorporating a 10% weight fraction of coarse Areca sheath particulates into epoxy resin significantly enhances the composite's macroscopic and vibrational properties, making it a promising material for various building applications like Partition panels, Ceiling Panels, and similar applications.

Published: October 2024

In February 2023, samples were gathered from the research location. Five samples were taken from each leaf of the aquatic plant Cyprus papyrus, which is a member of the Cyperaceae family, as well as from the Tigris and Euphrates rivers. The primary heavy metals detected were lead (Pb), iron (Fe), and copper (Cu). Samples were collected from various areas in Iraq, including the Diyala River site, AL Rustamiya site, Karbala site, Babylon site, and AL-Rashdiya site as a control. The samples collected from each site consisted of water and Cyprus papyrus. The ICP-AES analysis successfully determined the concentration of elements in the samples. The results indicated that the Pb average concentration in plants varied across different sites, with the highest levels recorded in Diyala River, followed by AL Rustamiya, Babylon, Karbala, and Rashdiya sites (Control) at 3.67, 2.11, 0.55, 1.26, and 0.046 ppm, respectively. These values were compared with the UNEP standard of 0.01 ppm. Similarly, water samples also exhibited elevated levels of Pb average concentration in the same order of sites, with values of 2.97, 0.48, 0.41, 0.35, and 0.0891 ppm, compared with the UNEP standard of 0.005 ppm. Furthermore, the analysis of Fe average concentrations in plants revealed the highest levels in Diyala River, Babylon site, AL Rustamiya site, Karbala site, and Rashdiya (Control) at 0.5, 0.4, 0.3, and 0.1 ppm respectively. In water samples, Fe average concentrations were also found to be elevated in the same order of sites, with values of 1.3, 0.07, 0.06, 0.03, and 0.01 ppm. The presence of Cu was not detected in any of the samples collected from either plants or rivers. The aim of this study was to evaluate the levels of heavy metals in the Iraqi environment and examine their impact on living organisms.
Approximation of the long-time dynamics of the dynamical system generated by the Ericksen–Leslie equations
Authors: Tachim Medjo T. , Tone C. , Tone F.
Published: October 2024

In this article we study the long-time dynamics of the dynamical system generated by the Ericksen–Leslie model. More precisely, we discretize the Ericksen–Leslie equations in time using the implicit Euler scheme, and with the aid of the discrete Gronwall lemmas we prove that the scheme is uniformly bounded. Moreover, using the theory of the multi-valued attractors we prove in a particular case the convergence of the global attractors generated by the numerical scheme to the global attractor of the continuous system as the time-step approaches zero.
Global Processing Deficit in Amnestic Mild Cognitive Impairment
Authors: Veronelli Laura , Daini Roberta , Mannino Alice , Rossetti Alessia , Gilardone Giulia , Corbo Massimo , Primativo Silvia
Published: October 2024

Background: Visuo-perceptual and visuo-attentional disorders, such as global processing deficit and simultanagnosia, are not routinely investigated in prodromal forms of typical Alzheimer’s disease, as amnestic mild cognitive impairment (MCI). Objective: This study evaluated global processing abilities through Navon’s classical paradigm in individuals with amnestic MCI and investigated the related visuo-perceptual and attentional components involved in simultanagnosia. Methods: Sixteen consecutive patients with amnestic MCI (6 single-domain, 10 multiple-domain) and 16 matched controls were requested to identify global and local elements of hierarchical Navon letters, and to name large and small solid letters. Results: While correctly identifying solid letters, patients with multiple-domain amnestic MCI were less accurate in processing the global level of hierarchical stimuli compared to controls. Single-case analyses suggested that global processing may also be impaired in single-domain amnestic MCI. In addition, patients with pathological performance in the Navon task showed perceptual and/or visual focal attention deficits. Conclusions: Early dysfunction of holistic processing can be detected in amnestic MCI. Visuo-perceptual and/or visual focal attention mechanisms, which have been shown to be damaged in Posterior Cortical Atrophy patients with simultanagnosia, may be impaired in individuals with amnestic MCI. Investigation and identification of global processing deficits in MCI could contribute to early diagnosis and longitudinal monitoring of the disease.
Preventing Donepezil-Induced Adverse Effects Through N-acetylcysteine Co-Administration
Authors: Park Jiae , Oh Jung-Pyo , Ku Kyojin , Jin Yeonsun , Kim Eun Jung , Lee Ji-Hyun
Published: October 2024

Background: Drug-induced adverse symptoms affect patients’ quality of life (QoL) during treatment. Understanding the underlying mechanisms of drug-induced adverse effects could help prevent them. As current drugs have limited effects in halting the progress of Alzheimer’s disease (AD), patients are required to take these drugs over a long period. The main obstacles to long-term compliance are drug-elicited side effects that deteriorate patient QoL. Objective: Donepezil, the most popular acetylcholinesterase inhibitor (AChEI) drug for AD, induces various side effects, especially at high doses. This study aimed to identify a drug that can attenuate the side effects of donepezil and investigate the underlying mechanisms. Methods: Five-week-old Sprague-Dawley rats received daily oral donepezil and N-acetylcysteine (NAC) for four weeks. General symptoms following administration were monitored daily to address drug-related adverse effects. Cytosolic calcium influx and generation of reactive oxygen species (ROS) after drug treatment were measured in vitro using C2C12 myotubes. Results: High-dose donepezil induced numerous adverse symptoms in male and female rats, which were markedly attenuated by co-treatment with NAC. NAC significantly reduced both acute and chronic muscle-related symptoms caused by donepezil. Additionally, in vitro studies showed that high-dose donepezil increased ROS and intracellular calcium ([Ca2+]i) levels in muscle cells, contributing to these adverse effects. NAC co-treatment dramatically reduced ROS and [Ca2+]i levels in muscle cells. Conclusions: Combined treatment with NAC effectively diminishes the adverse effects elicited by donepezil by regulating ROS and [Ca2+]i levels in the skeletal muscle, which could contribute to improving donepezil treatment in patients.
Producer and Consumer Behavior towards the Consumption of Halal Food and Beverages
Authors: Rizqa Agitsna Alya , Afandi Mukhamad Yazid
Published: October 2024

Introduction: Indonesia, as a country with a majority Muslim population, shows its concern for religion by consuming halal food and beverage products. Balanced consumption in Islam is implemented by avoiding tabzir and israf behavior. Objective: The method used is literature with qualitative data to describe community behavior from the producer and consumer sides when considering daily halal food and beverages. Method: The research approach used is a comparative qualitative approach. The research data was obtained from risk management reports contained in the annual reports of Bank Victoria Syariah and Bank Syariah Indonesia in 2023. Result: The result of this study is that consumers still think that halal food and beverages are only based on whether the product contains pork and dog meat and their derivatives or not. The obstacles from related agencies are moving institutions and processes that are still confusing and centralized, so there is a lack of human resources. Producer constraints are related to high costs, business management unpreparedness, and lack of socialization and awareness to register their products. Business actors' fraud against the halal label cannot be handled seriously with the policy of the halal product guarantee agency. Implication: This study increases awareness and adherence to halal standards among the public, including producers, consumers, and related institutions.

From ancient cold-blooded fishes to mammals, all vertebrates are protected by adaptive immunity, and retain immunological memory. Although immunologists can demonstrate these phenomena in all fish, the responding cells remain elusive for lack of defining markers and tools to study them. Fundamentally, we posited that it is longevity that defines a memory cell like how antibody production defines a plasma cell. We infected the common carp with _Sphaerospora molnari_, a cnidarian parasite which causes seasonal outbreaks to which no vaccine is available. B cells proliferated and expressed gene signatures of differentiation. Despite a half-year gap between EdU labeling and sampling, B cells retained the thymidine analogue, suggesting that these are at least six-month-old resting memory cells stemming from proliferating precursors. Additionally, we identified a lymphoid organ-resident population expressing exceptional levels of IgM as plasma cells. Thus, teleost fish produce the lymphocytes key to vaccination success and long-term disease protection, and immunological memory is universal and universally demonstrable.

The SARS-CoV‑2 coronavirus has become a major global health concern. Infection with SARS-CoV‑2 has caused millions of deaths worldwide, and the case fatality rate has been found to be largely related to pre-existing clinical conditions. The main clinical manifestation of COVID‑19 is the presence of respiratory symptoms. Severe complications of COVID‑19 are most often observed in people with significant medical histories. The SARS-CoV‑2 virus primarily attacks the respiratory system, causing pneumonia and acute respiratory distress syndrome, which can lead to severe systemic inflammation, multiple organ dysfunction, and death, especially in patients with pre-existing comorbidities. A number of meta-analyses strongly suggest that comorbid respiratory diseases, including chronic obstructive pulmonary disease and interstitial lung diseases, are factors in the development of severe forms of COVID‑19, worsening patient outcomes and survival rates. Studies have shown an association between adverse outcomes of COVID‑19 and the expression level of the angiotensin-­converting enzyme 2 (ACE2) in these patients. Regarding other respiratory system pathologies, such as bronchial asthma and cystic fibrosis, it is known that the main unfavorable factor is long-term immunosuppressive pharmacotherapy preceding infection. In this article, we highlight the main respiratory comorbidities to better understand the pathogenesis of COVID‑19.

The development of right ventricular hypertrophy (RVH) is a consequence of a large group of diseases that lead to increased pressure or volume load on the right ventricle. Electrocardiography (ECG) is a commonly used diagnostic method in clinical practice. This method allows for the identification of RVH signs in the early stages of examination. During the 20th century, more than 30 diagnostic criteria were developed. Several of these criteria are associated with worse prognosis, including increased mortality. Authors of international guidelines recommend the verification of criteria in local populations. Such studies have not been published in Russia, but according to data obtained from foreign researchers, the diagnostic properties of ECG criteria can vary significantly. In most cases, the criteria are characterized by low sensitivity and high specificity, which complicates early diagnosis of conditions leading to RVH development. It is proposed to increase the sensitivity of the method by using all the developed criteria or sets that include some of them. However, this approach may reduce the specificity of ECG diagnosis of RVH, and the selection of criteria for inclusion in diagnostic algorithms is not always based on scientific research data. This article analyzes the history of the development of RVH criteria, research data on their diagnostic capabilities, and ways to improve diagnostic algorithms.

This article aims to find out the implementation of the Qur'an Healing Technique (QHT) method in overcoming psychiatric disorders in inmates at the Indonesian Qur'an Healing Rehabilitation Islamic boarding school in Rokan Hulu District. This type of research is qualitative with a descriptive approach with observation, interview, and documentation data. The key informants in this study are the leaders of the Indonesian Qur'an Healing Rehabilitation Islamic boarding school, and 3 informants, namely therapists in the Indonesian Qur'an Healing Rehabilitation Islamic boarding school. From the results of the research on the implementation of the Qur'an Healing Technique (QHT) method in overcoming psychiatric disorders in inmates at the Qur'an Healing Indonesia rehabilitation Islamic boarding school, there are 3 stages. The initial stage is to carry out an assessment and continue with tazkiyatun nafs (cleansing of the soul) where the inmates are taught to pray five times in congregation, reciting, memorizing verses of the Qur'an, and being taught religious sciences that function as a pattern of forming human beings with good morals and fear Allah Swt. In the second stage, namely ruqyah shariah, with prayers and readings from the Qur'an and sunnah that contain requests for help and protection to Allah Swt to prevent or treat diseases and diseases. In the third stage, namely, hijamah which means cupping for cleansing dirty blood and wind, by removing the remaining toxins in the body through the surface of the skin by suctioning. Thus, the implementation of the Qur'an Healing Technique method for inmates with psychiatric disorders has undergone better changes than before, and they feel calmer.

Published: October 2024

This study investigated the impact of tool-work interface temperature during the turning process of a cylindrical workpiece made of 6061 aluminum alloy. The experiment utilized four different cutting fluids: palm oil-based cutting fluid (POBCF), neem seed oil-based cutting fluid (NOBCF), orange seed oil-based cutting fluid (OSOBCF), and mineral oil-based cutting fluid (MOBCF) using uncoated carbide cutting tool of grade H13A. Various machining parameters were considered, including spindle speed (180, 250, 355, 500 rpm), feed rate (0.105, 0.116, 1.4, 1.6 mm/rev), and depth of cut (0.5, 1.0, 1.5, 2.0 mm). The experimental design followed the Taguchi specified L16 (43) orthogonal array and was conducted on a Lathe Machine XL 400. To measure the tool-work interface temperature, an infrared thermometer (KM 690) was employed during the aluminum alloy machining process. Subsequently, a mathematical model for the tool-work interface temperature values was developed through regression analysis using Minitab 16. The significance of the chosen machining parameters and their respective levels on the tool-work interface temperature was determined using analysis of variance (ANOVA) and F-test. The findings indicated that machining under orange seed oil-based cutting fluid (OSOBCF) conditions resulted in a 9.02%, 16.4%, and 21.7% lower temperature at the tool-work interface compared to palm oil-based cutting fluid (POBCF), neem seed oil-based cutting fluid (NOBCF), and conventional oil-based cutting fluid (MOBCF), respectively. This suggests a potential for producing higher-quality products under orange seed oil cutting fluid conditions compared to other wet conditions.

Published: October 2024

The article describes the properties of the thermal protection coating of the gas generator of the hydrogen storage and supply system by two transfer functions with Hurwitz polynomials of the third order. Obtaining such transfer functions is based on the solution of the non-stationary heat conduction equation, represented in operator form using the integral Laplace transform, and in which approximating spline functions in the form of second-order polynomials are used. The article gives the solution of the non-stationary thermal conductivity equation, which describes the thermal processes in the heat-protective coating of the gas generator of the hydrogen storage and supply system under the thermal effect of a fire. This solution comes in the operator form for the surface temperature of the heat-protective coating on the side of the gas generator wall. The peculiarity of this decision is the presence of hyperbolic functions of an irrational argument in its composition. The structural and dynamic scheme of the thermodynamic system ‘gas generator wall – heat-protective coating’ is presented, the feature of which is the presence of two entrances. The signal at the scheme’s first input reflects the thermal effect of the fire, and the signal at the second input reflects the thermal state of the gas generator cavity. An equivalent mathematical transition to the description of thermal processes in the heat-protective coating of the gas generator of the hydrogen storage and supply system was carried out. This transition happened due to the use of spline functions, which approximate the hyperbolic functions of the irrational argument and are polynomials of the second order. The article gives a verbal interpretation of the algorithm for determining the transfer functions of the heat-protective coating of the gas generator of the hydrogen storage and supply system and also an example of its implementation. Furthermore, it shows that for the given conditions of functioning of the gas generator heat-protective coating, the relative errors in approximation of hyperbolic functions by second-order polynomials do not exceed 1.7 %, and the average relative error when equivalent replacement of transfer functions does not exceed 3.8 %.
Keywords: gas generator, hydrogen storage and supply system, thermal protection coating.
