Authors: Trujillo-Franco Luis Gerardo , Guízar-García Julio Alexis , González-Sierra Jaime , Rivera-Fernández Josué Daniel , Abundis-Fong Hugo Francisco , López-Vázquez Erik
Published: November 2024

Las ecuaciones diferenciales ordinarias tienen una considerable presencia en las diversas ramas de la ingeniería, dada su utilidad en el modelado y descripción de los fenómenos y procesos con los que el ingeniero tiene contacto en su quehacer creativo y de solución de problemas. Es por esta razón que, en los programas de estudio enfocados a la ingeniería, existe al menos un curso dedicado al tema de las ecuaciones diferenciales, donde se abordan los métodos analíticos y numéricos utilizados para su solución.
Hoy en día existen muchas herramientas tecnológicas que permiten ilustrar de manera muy interesante las aplicaciones de las ecuaciones diferenciales por medio de experimentos que, a pesar de ser básicos, brindan una motivación inigualable a los estudiantes al permitir corroborar con ejemplos prácticos, la utilidad y veracidad de la teoría que se les presenta en el aula y que en muchas ocasiones parece carente de utilidad y de relación directa con el mundo en el que se desenvuelven.
En este trabajo se proponen dos ejemplos de aplicación de las ecuaciones diferenciales en el modelado de sistemas físicos, utilizando una tarjeta Arduino Due y el ambiente de programación JupyterLab.

Published: November 2024

Este trabajo propone el diseño de un sistema enfocado en mejorar el proceso de gestión de operación y desactivación de un seguidor solar (SS) basado en lógica difusa. Lo anterior debido a que los SS usualmente se desactivan ante condiciones climáticas adversas siguiendo un principio de operación que se rige por comparaciones simples entre umbrales y parámetros asociados a las condiciones climáticas y, en consecuencia, se pierde de vista la energía disponible. Para validar la propuesta se realizó un procedimiento experimental que consta de dos etapas. La primera, se refiere a la prueba y ajuste del clasificador en un ambiente de simulación empleando escenarios que reproducen eventos registrados en bases de datos climáticas de la CDMX, así como su integración en un SS existente, y luego en la segunda etapa, se provee un análisis comparando los periodos de desactivación obtenidos con las condiciones reales. Finalmente se brindan conclusiones y propuestas de trabajo a futuro.

Authors: Nagesh  , Kanojiya Rahul
Published: November 2024

The purpose of this study was to evaluate the impact of a six-week recreational games training program on the quality of life, lung capacity, and flexibility of older adults aged 60 to 79 years residing in Gwalior city. The study included ten participants who were evaluated using the Sit and Reach Test for flexibility, a dry spirometer for lung capacity, and the OPQOL-35 questionnaire to assess their quality of life. Data were collected both before and after the intervention to measure the effects of the program.The intervention consisted of structured recreational activities designed to engage the participants physically, socially, and mentally. The results demonstrated significant improvements in the participants' overall quality of life and lung capacity, as evidenced by higher post-test scores. Enhanced physical well-being, reflected in better flexibility and increased lung capacity, was accompanied by improvements in emotional and social aspects of life, as reported in the OPQOL-35 responses.Statistical analysis revealed highly significant differences (p < .05) between pre- and post-test measures, confirming the positive effects of the intervention. These findings highlight the potential of recreational games as a practical and enjoyable approach to improving physical health, emotional well-being, and overall quality of life in older adults. Moreover, the study suggests that incorporating recreational activities into regular routines can serve as an effective strategy to promote healthy aging and prevent age-related declines in physical and mental health.By engaging older adults in meaningful and enjoyable activities, recreational games not only improve physical fitness but also foster social interaction and emotional support, contributing to a holistic approach to healthy aging. These results encourage further research and implementation of similar programs to benefit older populations in other communities.
BURNOUT AND OCCUPATIONAL STRESS AMONG SCHOOLTEACHERS DURING THE COVID-19 PANDEMIC IN BANGALORE URBAN AND BANGALORE RURAL
Authors: R Pushpalatha , E Keshamma
Published: December 2024

Burnout is a psychological condition brought on by ongoing stress that impacts people’s feelings, mental health, and physical behaviour. Burnout is more common among those whose jobs require communication with a client or a third party. Burnout predicts intention to leave and actual job turnover. A negative perception of the profession can lead to progressive absenteeism and, finally, to withdrawal from teaching. Burnout has historically been linked to the teaching profession. Teacher shortages are not a new issue. Shortages began in the mid-1980s due to increasing student enrolments and decreasing numbers of college graduates becoming teachers. During the pandemic a wave of change disrupted the education of the students. Both the students and the teachers were forced to adapt in a short time to new ways of working that include social distancing in classrooms, hybrid teaching and virtual instructions.  teachers have reported increased levels of anxiety, difficulties in communication and a lack of administrative support.  All these new stressors proximal to burnout added to the fear generated by COVID-19, which almost all people have experienced. Teachers are most valuable assets to any country who part their knowledge and guide the young minds to be a contributing citizen of the nation. The teachers are often pressurized with huge demands which usually leads to a lot of stress. Work related stress negatively affects the performance of the teachers.  Majority of teachers perceived their work-related stress due to dependent variables like gender, education, family income and economic instability. Job insecurity, poor students’ behaviour, ineffective leadership at departmental levels results in stress level of teachers and it also results in psychological distress among teachers. Educational status and years of experience of teachers are the factors responsible for creating stress among teachers. The aim is to study the stress and burnout among the schoolteachers. The sample consisted of 120 schoolteachers working in government and private schools as well as in rural and urban areas. Both male and female teachers constituted the sample for study. The teachers were residing in Bangalore urban and Bangalore rural areas. The teachers were administered the stress and burnout questionnaires.  A purposive sampling design was opted for the study. The mean, SD, and ‘t’ was computed using appropriate statistical measures. The result revealed that there was a significant difference in stress and burnout between schoolteachers of urban and rural areas as well as male and female teachers.

Review Study about Portable and Wearable Artificial Kidney Systems
Authors: Aljanabi Fanar , Lafta Hassanain Ali Hussein
Published: November 2024

Kidney renal failure is a life-threatening disease in which one or both kidneys are not functioning normally. The only available treatment other than a kidney transplant is to start on dialysis sessions, whether it is peritoneal or Hemo-dialysis[1].For some patients, the dialysis procedure is an exhausting and sometimes expensive trip to the specialized dialysis centers since it must be done about three times a week, depending on the physician's decision depending on the glomerular filtration rate of the kidneys[2-4].Different researchers have made many attempts over the years to replace conventional dialysis machines with more accessible at-home dialysis systems to provide patients with comfortable treatment sessions at the time they want without the need to change their lifestyle to fit the dialysis center's schedule.A review of the critical methods utilized in the creation and application of a portable dialysis machine that resembles the traditional dialysis center devices was conducted using a number of prior studies (research conducted between 2009 and 2024); the goal of all studies was to create a device that consists of filtering system, detection system to ensure there is no blood leakage and all parameters are within the acceptable limits, alarm system, and dialysate regeneration system, and each method will be described precisely in this review.As a result, the discussed studies found that using peristaltic pump pumps with a phase difference by half cycle between blood and dialysate will cause a higher urea clearance rate; multiple studies focused on the modification of the dialyzing filter to find that using Polyethene glycol surface-modified silicon nanopore membranes, dual-layer hollow fiber membranes, the use of BRECS cell therapy, carbon activated blocks, all contributed highly in enhancing the dialyzing process providing the patients with highly efficient blood purification session.
Detection of Oil Mineral Pollution in Tigris River from Aldora Refined using Absorbance Spectroscopy
Authors: Mohammed Thamer Mahmood , Ahmed Ahmed K.
Published: November 2024

Accurately identifying the kind and amount of dissolved metal salts in wastewater used in oil refining processes is an iconic feature of ultraviolet and visible absorption spectroscopy. This method relies on the dissolved metal salts' ability to absorb light at certain wavelengths after reacting with it. The experiments were conducted in a lab setting with a broadband source (200-800 nm) to measure the absorbance of dissolved element salts and precisely identify the lowest concentration up to 2 ppm. A mixture of the mineral salts from oil refining operations was prepared and diluted to different concentrations using a standard solution. This allowed us to study and compare this result with the absorbance behavior of the wastewater from the Al-Dora Refinery. The two results reinforced that we can accurately estimate the detection parameters for the lowest water contamination. These materials are lead nitrate (PbNO3), phenol, calcium carbonate (CaCO3), sodium chloride (NaCl2), sulfide (SO4), and nitrate (NO3). At wavelengths of 340, 404, and 741 nm, the concentrations (10, 20, 30, 40, 50, 60, 70, 80, 90, and 100) ppm were found, and for the concentration of 10ppm, the absorbance (0.15323, 0.15326, and 0.14685) was found, respectively. The process that has been tested with varying concentrations is considered and simulates the variation in river water concentrations caused by the river's water level and flow rate changes by the effect of rain abundance and thawing. It is fast, accurate data analysis, and a lower cost compared with the other chemical analysis and conventional methods.
Investigate the Durability and Structure Integrity of Recycled Aggregate Concrete Beam Over Time: A Literature Review
Authors: Abdulmajed Dalia Alaa Aldeen , Daud Sultan Ahmed , Alrshoudi Fahed
Published: November 2024

In term of sustainable practices, recycling plays a crucial role, particularly in the construction industry where the disposal of old structures generates significant waste. Recycling old concrete not only reduces the need for new natural resources but also eliminate waste accumulation. Numerous research study the behaviors of recycled aggregate concretes, practically focusing on the long term behaviours. A large number of studies have demonstrated that concrete made from recycled aggregate exhibits poorer long-term characteristics in comparison to aggregate from nature concrete. The long-term behaviour can be affected by three factor which is creep, shrinkage and tension stiffening. Greater management of these variables can enhance the RAC's long-term properties. The review will specifically focus on the influence of time dependent parameters i.e., creep, shrinkage, and loss of tension stiffening with time. Furthermore, it will explore the long-term deflection predicted from code used for deflection prediction, considering three codes: ACI, EC2, and the CSA code. The purpose of this paper is to enhance the understanding of long-term deflection of recycled aggregate concrete beam and evaluate the effectiveness of various factors that impact their structural performance.

A method is proposed for correctly determining the quantitative content of volatile components, including ethyl alcohol, in alcohol-containing products. The method is based on the use of sample density measurement data and chromatographic data for determining the quantitative content of volatile compounds. It is shown that in a number of cases the difference between the values of the volumetric content of ethyl alcohol in alcoholic products, calculated according to the interstate standard GOST 3639 and according to the proposed method, exceeds by several times the declared measurement error limit of 0.1 % by volume. The results obtained can be used to update state, interstate and international standards for quality control and safety of alcoholic and alcohol-containing products.

Published: November 2024

The aim of the study is to establish the association of variants of a number of genes involved in the reninangiotensin system with the severity of SARS-CoV-2 infection.

The study included 206 hospitalized patients with COVID-19: Group 1 – 99 patients with severe COVID-19; Group 2 ‒ 107 with moderate and mild forms of the disease.

Polymorphic variants of the ACE rs4646994, ACE2 rs2074192 rs2285666 and rs413031713 and LZTFL1 rs10490770 genes were analyzed using quantitative PCR with TaqMan probes (Primetech, Belarus) on a CFX96 thermocycler (Bio-Rad, USA). AGT rs699 and AGTR1 rs5186 gene variants were determined using a Rotor-Gene Q thermocycler (QIAGEN, Germany),  in accordance to the protocols of the manufacturer (Litekh, Russia).

We revealed that the genetic markers of the severe COVID-19 infection in the Belarusian patients are the heterozygous T/C genotype of the LZTFL1 rs10490770 variant, as well as the A-A haplotype of the ACE2 rs2074192 and rs2285666 loci, and the A-A-C allelic combination of the ACE2 rs2074192, rs2285666 and AGT rs699 genes. Genetic markers associated with mild/moderate severity of COVID-19 were also identified: heterozygous A/C genotype of the AGTR1 rs5186 variant,  G-G-T allelic combination at the ACE2 rs2074192 and rs2285666, AGT rs699 loci (among carriers of these gene variants,  the risk of severe disease is reduced).

The loci of the genes encoding the renin-angiotensin system – ACE2 rs2074192 and rs2285666, AGTR1 rs5186,  and the LZTFL1 rs10490770 genes, as well as allelic combinations between the ACE2 rs2074192, rs2285666 and AGT rs699 loci are informative markers for predicting the severity of COVID-19.

Published: December 2024

This study aimed to determine the effect of composite flour composition (wheat, sorghum, and tapioca) and carrageenan concentration on the quality of low-gluten white bread. This study used an experimental method with a two-factor completely randomized design (CRD), namely (1) composite flour composition (wheat:sorghum:tapioca) T1 = 50:25:25, T2 = 40:30:30, and T3 = 30:35:35, and (2) carrageenan concentration of 0.2 and 0.4%. Observation data were analyzed with SPSS software using ANOVA at the 5% significance level. Data that were significantly different were further tested with Honest Significant Difference test at the 5% significance level. The parameters observed included chemical quality (moisture content, ash content, and crude fiber content), physical quality (expandability, elasticity, bread pores, and staling), and organoleptic quality (aroma, taste, texture, crust color, and crumb color). The results showed that the treatment of different flour compositions and carrageenan concentrations had a significant effect on ash content, crude fiber content, expandability, elasticity, bread pores, and staling. However, there was no significant effect on its moisture content and organoleptic quality. To minimize the use of wheat flour, the composition of wheat:sorghum:tapioca flour 40:30:30 and carrageenan concentration 0.4% is the recommended treatment, with 24.35% moisture content (met the SNI requirements), 1.49% ash content, 4.08% crude fiber content, 68.69% expandability, 82.55% elasticity, pore size tends to be uniform between 12.08-19.11µm, staling time on the third day, and preferred by panelists because the texture is rather soft, the color of the crust is yellowish brown, and the color of the crumb is yellowish white.

Authors: Susanto Dwi , Huda Lailatul
Published: December 2024

The Ibadurrahman Majelis Taklim at Ponpes Baiturrahman, located in Jaddih Village, Socah District, Bangkalan-Madura, holds significant potential for developing creative industries based on local wisdom. However, the lack of structured mapping and empowerment strategies poses a major challenge to achieving economic independence and prosperity for the taklim congregation. This study employs the Asset-Based Community Development (ABCD) approach, a method of empowerment focusing on identifying, developing, and utilizing the assets or potential of the community. Data were collected through in-depth interviews with village officials, religious leaders (Ponpes Baiturrahman) and members of the taklim majelis to inventory the available assets. The mentoring results received positive feedback and demonstrated an improvement in the ability to map and identify both individual and community assets that could be effectively utilized to manage local potentials, such as craft skills, cultural wisdom and community networks. The empowerment strategies designed included skills training, creative product development and digital-based marketing. In conclusion, the ABCD approach successfully provides a strong foundation for developing creative industries based on local wisdom in this community, although further mentoring with a broader scope is recommended for more optimal outcomes

Lenguaje de estado e historia de la educación: dos ejercicios de desplazamiento en la mirada a los libros de texto gratuitos y la educación fundamental como objetos de estudio
Authors: Horta Méndez Alina Margarita , Martínez Tapia Yasser Viliulfo
Published: November 2024

Este artículo explora las consecuencias de asumir la crítica a la noción convencional de estado en la historia de la educación a nivel metodológico, específicamente en la construcción del objeto de estudio. Dicha crítica ha desarticulado al estado como una entidad unitaria y coherente, haciendo patente que esta imagen es, en parte, resultado de un lenguaje que lo constituye como tal. Es así que se propone un ejercicio de contraste en las maneras de concebir un objeto de estudio según si la investigación está permeada o no por tal lenguaje de estado. El contrapunto se apoya en dos investigaciones de maestría presentadas a través de dos viñetas: una primera que aborda el caso de los libros de texto gratuitos de la primera generación como dispositivos de formación ciudadana y una segunda que trata sobre la formulación de la educación fundamental bajo el auspicio de una organización internacional durante la posguerra. El ejercicio permite apreciar alternativas en la concepción tanto del tipo de procesos relatados como de la multiplicidad de sus protagonistas, diversificando con ello la cualidad de preguntas que orientan la investigación. Por lo anterior, se apela a considerar los efectos metodológicos que puede tener el lenguaje de estado en la historización de la educación.
El enfoque sociocultural de las emociones en la reconstrucción de los acontecimientos históricos
Authors: Legaspi Lozano Mayela
Published: November 2024

Este artículo propone la reconstrucción de los acontecimientos históricos desde el enfoque sociocultural de las emociones, para ello se plantea abrevar de dos propuestas, la tipología de las emociones y la historia oral para la reconstrucción de los sucesos históricos y la identificación de las emociones más relevantes que condujeron los acontecimientos. En este cometido se sugiere preparar a los participantes con un repertorio emocional para que durante las entrevistas puedan expresar las emociones que vivieron, en qué momento las sintieron, hacia quién y qué las generaba. En el análisis de la información convergerán paralelamente la reconstrucción de los acontecimientos y las emociones que intervinieron, tomando como guía la tipología de las emociones para situar de qué tipo de emociones se trata y cómo fueron interactuando para que los sucesos se desarrollaran con el cauce que tuvieron. Esta perspectiva representa un nuevo giro para comprender el pasado.
Discursos hegemónicos de la historia de México y resistencias paralelas. Una autoetnografía en diálogo con un profesor indígena
Authors: Cruz Hernández Jorge Luis
Published: November 2024

La autoetnografía es un texto evocativo que permite situar la experiencia de quien investiga en un contexto social, cultural y político más amplio. Una de sus finalidades es comprender la realidad situada de la y el investigador entre su pasado y su presente para transformarlo a múltiples escenarios de posibilidad. En este sentido, escribir la experiencia permite activar recovecos de la historia personal, aparentemente desarticulados, que dan lugar a una nueva lectura de la realidad. Esto es lo que Norman Denzin denomina “investigar con el corazón”. El presente trabajo emana de una investigación más amplia con fines de obtención del grado de Doctor en Pedagogía Crítica. Es una narrativa de mi historia personal en el intento de comprender los vínculos de la historia como disciplina y la dominación epistemológica de las comunidades indígenas. Para lograr el cometido recurro a la autoetnografía para revelar las formas en que la dominación epistemológica del pasado atraviesa el cuerpo y la subjetividad de las y los sujetos en su realidad concreta. En este caso, el conflicto generado por el discurso del pasado oficial de México y el imaginario construido sobre lo indígena me llevó a dialogar con mi padre, una persona perteneciente a una comunidad nahua de la Huasteca veracruzana y profesor jubilado del sistema indígena. Una de las reflexiones a las que llego es comprender que el proceso de dominación epistemológica no es ajeno a la formación del profesorado con raíces indígenas, ya que el discurso mesiánico del pasado oficial interpela su presente. Sin embargo, también pude visualizar que la resistencia al discurso oficial se lleva a cabo en prácticas extraescolares, cuya concepción indígena es revelada para la solución de conflictos y toma de acuerdos.
