ГОЛОДОМОР ТА РЕПРЕСІЇ У РАЙОНІ ДІЯЛЬНОСТІ ВАРВИНСЬКОГО ПОЛІТВІДДІЛУ МТС
Authors: Еткіна Ірина
Published: November 2024

Метою статті є розгляд трагедії Голодомору-геноциду та репресій українського народу у 1932–1934 рр. на матеріалах Варвинського політвідділу МТС.   Для цієї студії використано методологічний підхід «локальної історії», а також загальнонауковий метод індукції. Запропонована методологія дозволяє на основі великої кількості архівних джерел робити висновки як про явище Голодомору та пов’язані з ним репресії в цілому, так і визначати регіональні особливості. Наукова новизна розвідки полягає в тому, що проблема політвідділів МТС на матеріалах Чернігівщини не досліджена, на теренах України також не знайшла системного вивчення, незважаючи на велику увагу до тематики Голодомору в цілому.   Опрацьовані матеріали дозволили дійти таких висновків. Доведено, що матеріали політвідділів МТС є важливим історичним джерелом з тематики Голодомору-геноциду, до якого були залучені як документи самого політвідділу МТС, так і місцевих радянських установ, що перебували в його зоні діяльності. Голодомор-геноцид тривав у районі діяльності Варвинського політвідділу МТС і в 1933, і продовжувався у 1934 рр., де у внутрішній документації радянська влада визнавала наявність сімей без засобів для існування та факти пухлості й смерті на ґрунті голоду. Саме в цій місцевості було зафіксовано факти людоїдства та створення т. зв. «чорних штабів», тобто «фізичних методів впливу» задля вибивання хлібопоставок. Проаналізовано причини репресій місцевих керівників в означений час. Зроблено висновки про помсту сталінського керівництва українському селянству за опір, що селянство чинило радянській владі у 1917–1921 рр.

Comparative growth performance of Nile tilapia (Oreochromis niloticus) sex groups intank culture: A hormone-free approach for sustainable aquaculture in Dodoma, Tanzania
Authors: Michael Angelina , Mramba Rosemary Peter
Published: November 2024

Male tilapia are globally preferred in aquaculture for their superior growth and uniform harvest sizes. However, hormonal sex reversal techniques used to produce all-male populations can pose health and environmental risks. This study investigated the growth performance of manually separated monosex males, monosex females, and mixed-sex groups of Nile tilapia in tank culture as a sustainable and hormone-free alternative. Over six weeks, the study measured various morphometric parameters, weight gain, specific growth rates, water quality parameters, and condition factors. The fish were fed isonitrogenous commercial feed, and the feeding regime was adjusted based on their weight. Results revealed that monosex tilapia groups attained higher growth rates than mixed-sex groups, with males achieving an average final weight of 56.5 g, followed by females at 53.3 g, and mixed-sex groups at 43.3 g. Males had higher morphometric values compared to females and mixed-sex groups. The water quality parameters remained optimal across all groups, indicating that sex composition does not impact water management. Monosex females and mixed-sex groups exhibited better condition factors. The study concludes that tilapia farming can be effectively conducted with either mono-sex male or mono-sex female tilapia, as their growth rates do not differ significantly. Further research and development of techniques to ease the separation of sexes and enhance the growth rates of monosex female tilapia are recommended as a viable, hormone-free alternative for sustainable aquaculture.
A fractional-order model of COVID-19 and Malaria co-infection
Authors: Iwa Livinus Loko , Omame Andrew , Inyama Simeon Chioma
Published: November 2024

This paper explores the co-infection dynamics of coronavirus disease 2019 (COVID-19) and Malaria using Caputo-type fractional derivative to further understand the disease interactions and implement effective control strategies. We demonstrate the positivity and boundedness of the solution through Laplace transform techniques and establish the existence and uniqueness of the solution, showcasing model stability using fractional-order stability theory. Simulation experiments across varying fractional orders and disease classes offer insights into the co-infection dynamics. This is a new model and the findings underscore the potential impact of control measures on mitigating co-infection under endemic conditions. We conclude that infection with malaria does not guarantee immunity to COVID-19 and infection with COVID-19 as well does not guarantee immunity to malaria.

El filtro de Kalman como herramienta de mejora de la seguridad y fiabilidad del transporte ferroviario
Authors: García Márquez Fausto Pedro , Schmid Félix , Conde Collado Javier
Published: November 2024

En el seno de la Unión Europea, la política común del transporte ferroviario encuentra su origen a nivel constitucional en el Título IV del Tratado de Roma (1957). Desde entonces, las empresas operadoras del sector han sido, en su gran mayoría, de carácter estatal, cuyo mercado de actuación ha sido monopolista. Estas empresas han venido soportando grandes déficit, respaldados con ayudas y/o subvenciones públicas, así como, con políticas de actuación centradas en el ámbito social y estratégico de la Nación. Todo ello ha perdurado hasta 1991, dictándose nwnerosas normas con el fin de regular y liberalizar dicho mercado del sector del transporte.
Las nuevas directivas ponen de manifiesto la necesidad de incrementar la seguridad y fiabilidad en este tipo de transportes como consecuencia de dicha liberalización, tanto por la salud de los pasajeros como por la de los trabajadores, intentando con ello evitar las consecuencias catastróficas que se han estado dando tras dichas liberalizaciones en otros países, como es, por ejemplo, en el Reino Unido. Para awnentar la fiabilidad de estos sistemas, en los cuales se emplean normalmente acciones de mantenimiento predictivo, se suelen utilizar el filtrado y la estimación como principales técnicas de tratamiento de las señales consideradas. El Filtro de Kalman permite estimar estados futuros en base a datos históricos. El Filtro de Kalman es empleado en este trabajo como herramienta para filtrar la señal que se está tratando. Los autores de este artículo han desarrollado un Filtro de Kalman aplicado a la señal de la corriente eléctrica del motor de accionamiento de las agujas de un desvío ferroviario, mostrando las mejoras obtenidas para poder detectar fallos con una alta fiabilidad.

Authors: Corvalán Roberto M. , Osses Mauricio , Urrutia Cristian M. , González Patricio A.
Published: November 2024

Se desarrolla una metodología del tipo macro-escala para estimar emisiones vehiculares en centros urbanos donde no existen modelos de trasporte que entreguen la información necesaria para aplicar metodologías convencionales del tipo micro-escala, basadas en información relativa al nivel de actividad de las diferentes categorías vehiculares. Se obtienen, en primer término, correlaciones entre nivel de actividad y emisiones a partir de inventarios de emisiones desarrollados para 8 centros urbanos de Chile, donde se dispone de modelos de transporte que permiten aplicar los modelos de emisiones convencionales. Se obtienen luego funciones de correlación entre nivel de actividad y variables explicativas de tipo socio-económicas y demográficas, haciendo uso del método de mínimos cuadrados de Gauss-Newton. Se aplica la metodología a 17 centros urbanos obteniéndose inventarios de emisiones que permiten identificar las responsabilidad que sobre las emisiones de contaminantes atmosféricos tienen los diversos grupos de categorias vehiculares presentes en los parques vehiculares respectivos.

Authors: Barbieri Andrés , Samat David , Molina Héctor
Published: November 2024

Durante las operaciones transitorias de un motor, se requiere de una exacta relación aire combustible, a los efectos de optimizar la eficiencia y reducir las emisiones. Motores que de fabrica no están acondicionados para funcionar con gas y son transformados para funcionar con combustibles gaseosos (GNC) en los que se utiliza para su dosado mezcladores tipo Venturi, no brindan una respuesta satisfactoria para las condiciones antes expuestas. El presente trabajo describe y desarrolla un estimador a lazo abierto de la relación aire-GNC aspirada por los cilindros para mejorar las condiciones transitorias y de regulación de los motores a GNC con mezcladores tipo venturi, utilizando para tal efecto sensores másicos de caudal en el pasaje del aire y del combustible gaseoso. La clave del estimador está en la inclusión de la dinámica de los sensores másicos, como se demuestra en los resultados de la simulación.

Authors: Vallellano Martín Carpóforo , Erce J. J. , García-Lomas Francisco Javier
Published: November 2024

La industria moderna demanda un diseño y una fabricación más eficiente de sus productos. Actualmente existe una tendencia generalizada hacia la simulación y optimización numérica de los procesos industriales, entre los que se encuentran los procesos de conformado plástico. Este trabajo presenta un estudio críticosobre la capacidad de diferentes criterios de fractura dúctil para predecir el fallo en los procesos de conformado plástico de chapa. Para ello, se analiza no sólo su bondad para predecir el instante y zona de fallo, sino también su capacidad para reproducir el proceso físico de fallo de acuerdo con la evidencia experimental. Entre los criterios explorados están los propuestos por Cockcroft y Latham, Brozzo et al., Oyane et al. y Chaouadi et al.. Asímismo, se propone un nuevo criterio que surge como una modificación del criterio de Freudenthal para in cluir el efecto de la presión hidrostática en el fallo. Usando el MEF se realiza la simulación de un proceso de embutición axilsimétrico y se implementan numéricamente los distintos criterios de fallo. Las predicciones ob tenidas se comparan con resultados experimentales.

Banco de pruebas para medida de fricción en pistones
Authors: Casanova Kindelán Jesús , Aguirre Montoya Viviana
Published: November 2024

Se ha desarrollado un banco de pruebas con el propósito de estudiar las fuerzas de fricción que experimentan los pistones en un motor de combustión interna. Estas fuerzas se han medido utilizando el método IMEP desarrollado por Uras y Patterson. Este método se basa en el balance de fuerzas que actúan sobre el pistón determinándose la fuerza de fricción con la medida simultánea de la presión de los gases de combustión y la fuerza en la biela. Con el propósito de realizar el estudio en condiciones reales, se ha utilizado un motor de gasolina que fue adaptado a monocilíndrico. El motor térmico se acopla a un motor eléctrico que cumple las funciones de arranque y arrastre. El pistón y la biela del cilindro 1 se dejan activos. Los elementos en los otros tres cilindros se remplazan por contrapesos y se añade masa al volante para disminuir el desequilibrio producido. Se describen las modificaciones hechas al motor y a los sistemas periféricos. Para medir los esfuerzos en las bielas, éstas se han instrumentado con galgas extensométricas conectadas en puente de Wheatstone completo para compensar las variaciones de temperatura y pandeo. El cable que lleva la señal de la galga al amplificador es conducido por un brazo sujeto a la cabeza de la biela y a una estructura construida fuera del motor, modificando para ello ligeramente el bloque del mismo. La presión de los gases en el cilindro se mide con un transductor piezoeléctrico integrado en la bujía. Igualmente se utilizan diversos instrumentos para el control del funcionamiento del motor. Se describen y justifican las soluciones técnicas adoptadas, así como los diferentes ensayos que se realizan con el propósito de comparar la fricción en distintas condiciones de operación del motor y se presentan algunos resultados que muestran la viabilidad del banco diseñado.

China's Investment in Bangladesh: Backdrop of Debt Trap Diplomacy
Authors: Rahman Md.Mizanur
Published: November 2024

This research investigates the implications of Chinese investment in Bangladesh, particularly in the context of concerns surrounding debt trap diplomacy. As China extends its Belt and Road Initiative (BRI), Bangladesh has emerged as a significant recipient of Chinese loans and investments, encompassing infrastructure projects such as ports, power plants, and highways. While these investments are poised to bolster Bangladesh's economic development, they also raise concerns about the potential for unsustainable debt levels and the erosion of sovereignty. This study delves into the economic, political, and social ramifications of Chinese investments in Bangladesh. Through a mixed-methods approach combining quantitative analysis of debt sustainability indicators and qualitative assessments from stakeholder interviews, the research examines whether Chinese funding is leading to a debt trap scenario. Preliminary findings suggest that while Chinese investments have accelerated infrastructure development, they have also increased Bangladesh's debt burden and dependency on China. Furthermore, the strategic placement of investments suggests potential geopolitical motivations behind Chinese funding. This research aims to contribute to the broader discourse on the impact of Chinese foreign direct investment in developing countries, offering policy recommendations for Bangladesh to navigate the complexities of foreign financing without compromising its economic sovereignty. The study underscores the necessity for rigorous debt management and transparent investment policies to mitigate the risks associated with large-scale foreign loans.

Data from 172 franchisees were analyzed using a quantitative approach to test ten alternate hypotheses related to operational aspects such as training adequacy, brand recognition, and market competition. The results revealed consistent perceptions among franchisees, with no significant differences across age demographics. Specifically, franchisees uniformly accepted perceptions regarding the effectiveness of the franchise model, adequacy of support, and the influence of brand recognition, indicating a strong alignment in understanding the model's benefits. However, the findings also emphasized significant competition from local independent cafés, highlighting the need for strategic adaptations. The study's practical implications suggest that franchisors should prioritize standardized training and support systems, improve marketing strategies, and cultivate strong franchisee-franchisor relationships to drive growth. The research underscores the importance of addressing competitive dynamics and continuously improving support systems. Future research is recommended to explore longitudinal impacts, diverse demographic influences, and the integration of digital transformation within franchise operations. This study provides valuable insights into franchise effectiveness, offering guidance for practitioners seeking to optimize franchise performance in the café and restaurant sector

Authors: Prajapati Vikas , Joshi Dipak , Vidani Jignesh
Published: November 2024

This study explores consumer awareness regarding health issues caused by the consumption of cold drinks in Ahmedabad city. The research examines associations between age, reasons for cold drink consumption (e.g., taste, habit, socializing), and the occurrence of health problems such as diabetes, digestive issues, and dental problems. It also investigates how consumers gather information about the health impacts of cold drinks, with a focus on sources such as social media, family/friends, schools, and health professionals. The findings reveal weak associations between age and reasons for consumption, suggesting that cold drink preferences are not strongly age-dependent. However, digestive issues are more significantly associated with cold drink consumption compared to other health risks like diabetes and dental problems.The study also highlights the importance of labeling and natural ingredients in influencing consumer choices, as well as the role of government campaigns in raising health awareness. Practical implications include the need for targeted public health campaigns, clearer product labeling, and promoting healthier beverage alternatives. The findings suggest that age-specific interventions, especially leveraging social media for younger consumers, can be effective in raising awareness and promoting healthier behaviors. Future research should explore psychological and behavioral drivers, evaluate the effectiveness of public health interventions, and investigate long-term health impacts to provide deeper insights into cold drink consumption patterns and their health consequences

Authors: Yolanda Sihaloho
Published: November 2024

This research aims to analyze the impact of pricing on the purchasing decisions of A&R Juice MSMEs. The research method used is qualitative, with data collection conducted through interviews with MSME actors. The results of this study indicate that if there is an increase in the pricing variable, then the purchasing decision variable will also experience an increase. This means that the pricing strategy applied can enhance purchases in the A&R Juice MSMEs, where pricing pressure is achieved through product diversification or variation. However, it is necessary to conduct a risk analysis to minimize errors in product diversification.

Published: November 2024

With the improvement of 5G communication service, the need for edge computing has become more apparent. The Mobile Edge Computing service (MEC) has become one of the best solutions for mobile User Equipment (UE) data processing. MEC provides more context-aware local processing of UE's data. Meanwhile, the MEC needs to manage the heterogeneous nature of UEs and the type of data format they provide. Therefore, a Heterogeneous Data Service Bus is developed to manage different types of data formats and organize them in efficient manner. We propose a software architecture model to address the management of data heterogeneity within computing edges. The architecture discussion showcases its applicability and proper handling of heterogeneous data in the Edge Computing Environment.

Published: November 2024

Indonesia is a country situated in the middle of two seas encircling continents. Indonesia is situated in the area of the world's most active earthquakes, as shown by its location on tectonic plates encircled by active volcanoes. Because of this, Indonesia is susceptible to a variety of natural calamities, including tsunami and eathquakes. An earthquake is a sudden, mild to strong shaking of the ground brought on by a shift in the earth's plates. Victims of earthquakes may have psychological and physical effects. For victims, it causes severe anguish and sadness. Examining the degree of trauma experienced by children following the earthquake in Kajai, West Pasaman, West Sumatra, Indonesia, is the goal of this study. In West Kajai Pasaman, West Sumatra, 303 post-earthquake children were the sample for this quantitative study, which used a descriptive research approach. According to the study's findings, mild trauma was experienced by 30.4% of post-earthquake children, moderate trauma by 62.7%, and severe trauma by 6.9% of the population. It is anticipated that this study would draw attention to the number of traumatized youngsters in Kajai village. The regulatory agencies will find these insights useful in reducing

Application of Humanistic Learning Theory in Increasing Student Learning Motivation
Authors: Ursula Putu Abda
Published: November 2024

The educational process must pay attention to the development of potential, character, and learning motivation, not just achieving academic results. The absence of student learning motivation, which can affect their achievement and their involvement in learning activities, is one of the main challenges faced by teachers during the learning process. In this context, humanistic learning theory offers a perspective that emphasizes how important it is to meet a person's psychological and emotional needs so that they can learn optimally and feel valued as individuals. The most important finding of this study is that humanistic learning theory has great potential to increase students' desire to learn. If this theory is applied more widely, it can help solve the problem of lack of desire to learn which has been a problem in the world of education. Theoretically and practically, this study makes a significant contribution to the advancement of science. Theoretically, this study strengthens the idea that the humanistic approach is still relevant in the world of modern education. Practically, this study offers direction to educators to concentrate more on students' emotional needs as one important way to increase their desire to learn. Although this study is very useful, the results cannot be generalized. To find out how humanistic learning theory can be applied to various educational contexts, further studies are needed. This will pave the way for additional research

Phosphorus is one of the most widely studied chemical elements to identify paleoanthropogenic activity. Various methods have been used to analyse phosphorus in archaeological soil, however, general recomendations for the adequate choice of the research method are yet to be formulated. The search for a reliable and efficient method to estimate phosphorus of anthropogenic origin in soil is important from the applied point of view, especially in the case of a large series of samples.The aim of these studies was to test different P extraction methods with samples of the known archaelogical context. The sample texture, elemental composition (XRF), pH, loss on ignition at temperatures of 550 and 1000 °C have been determined. The P extraction methods using aqua regia, 1 and 5M HCl, citric acid, Mehlich 2 and Mehlich 3 extractants, as well as sample ignition at 550 ir 800 °C have been tested. It has been determined that the proportion of total P (XRF) extracted by nearly all the methods was higher and in a better agreement with the total P in sand soil samples than that in loamy sand samples. The extraction of sieved/unmilled and ignited at 550 °C soil with 1M HCl appeared to be a reliable and sustainable method and therefore was best suited for the samples of the series studied.
