Published: May 2024

En México, alrededor del 5 al 7% de la población con diabetes (DM) tiene alguna amputación en miembros inferiores, representan el 81% de las amputaciones en México con 28 470 casos anuales dentro de un total de más de 935 mil personas con amputación. Sin embargo, a pesar de esta alta prevalencia es una población poco estudiada. El presente trabajo pretende evaluar diferentes variables psicológicas en personas con amputación unilateral de miembro inferior por DM tipo 2 (ADM) y sujetos control (SC) en México. Un segundo objetivo es correlacionar las variables psicológicas con el desempeño motor en sujetos con ADM. Se realizó un estudio transversal con muestreo no probabilístico por conveniencia en personas con ADM y SC. Se evaluó la movilidad del amputado de miembro inferior sin o con prótesis (AMPPRO), dominios cognitivos (MoCA-E), síntomas de ansiedad y depresión (BAI, BDI-II), salud física y mental (SF-36) y síntomas psicopatológicos. Los resultados mostraron diferencias significativas en los dominios de MoCA, excepto en Identificación, obteniendo los ADM menores puntuaciones. También se obtuvieron diferencias en los dominios de SF-36 de función y rol físico y salud general, con menor puntuación en el grupo ADM. No se obtuvieron diferencias en BAI ni BDI-II. La puntuación AMPPRO se correlacionó positivamente con la puntuación de función física, y negativamente con la de BAI y BDI-II.  En conclusión, los sujetos con ADM muestran un desempeño más bajo en las funciones visoespacial, lenguaje, atención, memoria, abstracción y orientación. Esto indica que los pacientes amputados requieren una atención integral y no solamente el reemplazo del miembro perdido por una prótesis.

Abstract: Possibilities for integration of vortex tube with automotive radiator for more effective cooling of automotive engine is the aim of the overview. An automotive radiator/heat exchanger is a device which helps maintain the working temperature of the engine. The vortex tube is a device which provides low temperature and high temperature output with pressure as an input. Because of its compact design and little maintenance requirements, it is very popular in heating and cooling processes. Despite its simple geometry, the mechanism that produces the temperature separation inside the tube is complicated. In addition, thermal and kinetic energy considerations have been used to explain temperature separation. There have also been plenty of numerical analyses that confirm earlier experiments. One fact remains, however. In this study, the past investigations of the design criteria of vortex tubes were overviewed and the detailed information was presented on the design of them. Vortex tubes were classified and the type of them was described. All criteria of vortex tubes were given in detail using experimental and theoretical results from the past until now.

Published: May 2024

Abstract: Efforts to create technology for automatically detecting fake news are actively underway as the spread of misinformation on social media continues to escalate. However, most of these approaches primarily concentrate on the linguistic and structural aspects of fake news, such as identifying sources or authors, message length, and the frequency of negative language. In contrast, our study introduces a phony news detection model leveraging machine learning that incorporates user behaviors, news, and social capital-based social network dynamics. We used the XG Boost model to evaluate each feature's significance and identify the critical elements affecting the identification of fake news to capture the variables related to the spread of phony news entirely. We implemented SVM, RF, LR, CART, and NNET, well-known machine learning classification models, using these identified factors and assessed how well they detected bogus news. This work used a cross-validation process to prevent overfitting and to generalize the established models. Additionally, the predicted accuracy of the established models was compared. The RF model had the best forecast accuracy, about 94%, while the NNET had the worst performance rate, about 92.1%. As disinformation is created and disseminated with growing sophistication, the results of this study should improve the effectiveness of false news detection systems.
Formulation and Evaluation of Different Polymer-Coated Spherules from Granules
Authors: Shingare Vishal S.
Published: May 2024

Abstract: A novel spheronization technique is reported here for forming spherules from granules using FDA-approved excipients and common pharmaceutical unit operations. Aspirin is used as a drug to check stability during the process. Spherules are made by “bed coating during sliding” (BCDS) of granules. The spherules provide an opportunity to modify their surface properties by polymer film coating. It improves the functional properties such as appearance, drug release, and integrity of particles during the processing of spherules. Spherules with two size ranges (sieves no 22 and 44) are compared. These spherules are further coated with polymers to show the adaptability of the process. Microscopical evaluation reveals that several edges (90° and 45°) are less for spherules compared to granules. The angle of Repose and packing parameters appeared excellent. Different polymer coating drugs give different release profiles as per the properties of the polymeric drugs. This is a versatile platform delivery system for developing advanced drug delivery systems (ADDS). However, the stability of aspirin is affected by the wet process may be because aspirin is a hydrolytically labile drug. Granules and pellets are not necessarily spherical. Coated spherules can also be an option for coating as against to coating the tablet.

Published: May 2024

This study investigates the effects of trade facilitation policies on intra-manufacturing exports among ECOWAS member states. Utilizing the Generalized Method of Moments (GMM) linear model, this research analyzes data from 2015–2020 for the ECOWAS member states. The findings reveal that trade facilitation policies in the ECOWAS region fall below the global average. This discrepancy is primarily due to the extensive bureaucratic processes in the region, leading to increased costs for exporting and importing goods. Consequently, there is a significant need for trade facilitation to enhance intra-manufacturing exports within ECOWAS. Based on these insights, the study recommends several policy interventions to improve trade flow and bolster intra-manufacturing exports in the ECOWAS region. These include a stronger commitment to trade agreements among ECOWAS member states, the adoption of information and communication technology (ICT) to streamline trade processes and reduce bureaucratic delays associated with document processing for exports and imports, the strengthening of institutional frameworks within the member states, and the formulation of policies aimed at increasing industrialization levels to enhance manufacturing exports throughout the ECOWAS region.

The development of advanced anode materials for lithium-ion batteries
that can provide high specific capacity and stable cycle performance is
of paramount importance. This study presents a novel approach for
synthesizing molecular-level homogeneous carbon integration to porous
SiO nanoparticles (SiO@C NPs) tailored
to enhance their electrochemical activities for lithium-ion battery
anode. By varying the ratio of the precursors for sol-gel reaction of
(phenyltrimethoxysilane (PTMS) and tetraethoxysilane (TEOS)), the carbon
content and porosity within SiO@C NPs is precisely
controlled. With a 4:6 PTMS and TEOS ratio, the SiO@C
NPs exhibit a highly mesoporous structure with thin carbon and the
partially reduced SiO phases, which balances ion and
charge transfer for electrochemical activation of SiO@C
NPs resulting remarkable capacity and cycle performance. This study
offers a novel strategy for preparing affordable high capacity
SiO-based advanced anode materials with enhanced
electrochemical performances.

The rhizosphere influence on the soil microbiome and function of crop
wild progenitors remains virtually unknown, despite its relevance to
develop microbiome-oriented tools in sustainable agriculture. Here, we
quantified the rhizosphere influence – a comparison between rhizosphere
and bulk soil samples – on bacterial, fungal, protists and
invertebrates communities and on soil multifunctionality across nine
crop wild progenitors in their sites of origin. Overall, rhizosphere
influence was higher on abundant taxa across the four microbial groups,
and had a positive influence on increased rhizosphere carbon storage and
nutrient contents compared to bulk soils. The rhizosphere influence on
abundant soil microbiomes were more important for soil
multifunctionaility than rare taxa and envirommental conditions. Our
results are a starting point to uncover the roles of both abundant and
rare soil taxa in enhancing multifunctionality in agroecosystems.

Securing a favorable place in the global trade market and achieving sustainable economic growth are among the objectives of developing countries. A country's commercial status has significantly improved as a result of increased exports and improved economic conditions brought about by the growth of its domestic output. Medicinal plants (MPs) are a significant and productive part of the economies of the majority of countries, including Afghanistan. Afghanistan has an exceptional capacity for the production and export of MPs and herbal medications because of its unique geopolitical situation and climate. Because of their varied temperatures and geographic locations, the many provinces in the country offer considerable possibilities for the investment, commerce, and cultivation of these species. In addition to receiving basic healthcare, they may create jobs, stop the loss of the green flora so that certain significant wild species can be domesticated, and protect the environment with careful planning in this area. This article's goal is to review the contribution that MPs have made to the country's commerce and economic growth. Based on the results, it can be said that MPs have a multifaceted function in the expansion and growth of the Afghanistan's economy and commerce, and taking this into account, it is possible to understand the significance of these products on the list of significant exports from the Country. MPs are viewed as a potential link between biodiversity preservation, accessible healthcare, and sustainable economic growth.

En la actualidad, uno de los desafíos primordiales que enfrentan los estudiantes de niveles educativos primario y secundario es la deficiencia en la comprensión lectora, lo cual repercute de manera significativa en el proceso de aprendizaje de las matemáticas a escala nacional, como evidencian los resultados obtenidos en la evaluación PLANEA 2017 (Plan Nacional para la Evaluación de los Aprendizajes[1]). Por eso, en el presente estudio se procuró responder la siguiente interrogante: ¿cuál es la relación entre el nivel de comprensión lectora y el desempeño en matemáticas en alumnos de tercer año de la Escuela Secundaria Técnica nro. 71, ubicada en Torreón, Coahuila, México? Para responder esta pregunta se llevaron a cabo análisis estadísticos que comprendieron los siguientes pasos: 1) se evaluó la fuerza de asociación entre las variables de comprensión lectora (X) y matemáticas (Y), lo cual arrojó los siguientes resultados: la prueba de correlación de Rho de Spearman (  reflejó una correlación positiva baja, lo que indica que un incremento en la comprensión lectora se asocia con un aumento en el desempeño en matemáticas, aunque no necesariamente en la misma magnitud. Al respecto, cabe destacar que dicho coeficiente no establece una relación causal entre las variables, sino que ofrece una perspectiva sobre su comportamiento conjunto. 2) Se observó que el promedio de aciertos en comprensión lectora (22.16) fue significativamente superior al promedio en matemáticas (19.06), y 3) se determinó la ecuación lineal de regresión de Y respecto a X, que proporciona una aproximación de la relación de dependencia entre ambas variables, expresada como Y=6.472 + 0.568 X. Esta ecuación indica que cuando el nivel de comprensión lectora (X) es igual a 1, el desempeño en matemáticas (Y) es 0.568. En términos más claros, por cada incremento de 10 aciertos en comprensión lectora, se proyecta un aumento de 5.68 aciertos en matemáticas.

Morphological changes in testes during ethanol poisoning have not been studied enough. The aim of the study was a quantitative morphological analysis of the features of the remodeling of blood vessels of the hemomicrocirculatory bed of the left and right testes at conditions of ethanol intoxication. The structures of the left and right testis of 30 white male rats, which were divided into 2 groups, were morphologically and morphometrically studied. The 1 group included 15 intact animals, the 2-15 rats, which were injected intragastrically with a 30 % ethanol solution at the rate of 2 ml per 100 g of body weight for 28 days once a day. A month after the start of the experiment, the experimental animals were euthanized by bloodletting under thiopental anesthesia. Histological and semithin sections were made from testes. The outer and inner diameters, wall thickness of arterioles, precapillary arterioles, hemocapillaries, postcapillary venules and venules were determined. Quantitative indicators were processed statistically.It was established that twenty- eight days of ethanol intoxication in laboratory sexually mature white male rats leads to pronounced remodeling of the blood vessels of the hemomicrocirculatory bed of the left and right testes, which is characterized by narrowing of the lumens and thickening of the walls of its arterial (arterioles, precapillary arterioles) and exchange (hemocapillaries) vessels. pronounced expansion and thinning of the walls of postcapillary venules and venules, venous hemoptysis, hypoxia, dystrophic- necrotic changes in cells, stromal structures, inﬁ ltration and sclerosis. The revealed remodeling of blood vessels of the hemomicrocirculatory bed in conditions of ethanol poisoning dominates in the left testicle.

muerte judicial del “Plan B”
Authors: Martín Reyes Javier
Published: May 2024

La reforma electoral de 2022-2023 —el “Plan B” del presidente López Obrador— pretendía transformar profundamente el sistema electoral mexicano. Por sus múltiples problemas de inconstitucionalidad, fue controvertida y eventualmente invalidada en su totalidad por la Suprema Corte. Se ha dicho que esta decisión muestra cómo las instituciones y contrapesos han frenado el retroceso democrático en México. Sin embargo, la Corte anuló esta reforma exclusivamente por violaciones al procedimiento legislativo y no analizó ninguno de los aspectos sustantivos del Plan B. Consecuentemente, después de 2024, se podrían aprobar reformas similares o idénticas. Este artículo muestra que la decisión de la Corte brindó una solución contundente de cara a las elecciones de 2024, pero constituyó un precedente acotado para futuras reformas.
paridad y la representación sustantiva de las mujeres en México
Authors: Gilas Karolina
Published: May 2024

El presente artículo busca examinar el ejercicio de la representación sustantiva por las legisladoras mexicanas y explorar la relación entre la representación descriptiva y la representación sustantiva de las mujeres en el ámbito político mexicano. El trabajo evidencia los patrones en la presentación y aprobación de las iniciativas feministas, evidenciando que, si bien las mujeres presentan la mayoría de las iniciativas de corte feminista y su presencia en los legislativos contribuye a la articulación de los intereses de las mujeres, esta articulación resulta limitada a solo ciertas agendas y no siempre corresponde a las perspectivas o soluciones progresistas.
Presentación del Dossier ¿La democracia a las urnas? Las elecciones de 2024 en México
Authors: Monsiváis-Carrillo Alejandro , Cisneros Yescas Gerardo Isaac
Published: May 2024

México es uno de los 76 países en el mundo que celebran elecciones en 2024. Los artículos contenidos en este Dossier examinan importantes riesgos y oportunidades asociados a las elecciones de 2024 en México. Uno de esos riesgos puede ser que la democracia “se juegue” en la boleta electoral. Si bien las elecciones son un mecanismo esencial de la democracia, en ellas no se compite únicamente por los votos. Hay ocasiones en las que también se disputa la integridad de los comicios y el futuro mismo de la democracia. Este texto examina esa posibilidad y discute las aportaciones de los artículos para comprender el significado democrático, las oportunidades y las fortalezas de las elecciones mexicanas de 2024.
Menilik makna ritual ruwatan air menurut pandangan ilmu etnobiologi dan perspektif Islam di Desa Penanggal Kecamatan Candipuro Kabupaten Lumajang
Authors: Wulandari Adelia , Bahri Saiful
Published: May 2024

Ruwatan air adalah salah satu upacara adat yang dilakukan oleh masyarakat di desa Penanggal yang terletak di lereng timur Gunung Semeru dengan tujuan wujud syukur masyarakat desa setempat terhadap sumber air yang melimpah. Meskipun upacara adat ini merujuk kepada satu komponen hayati yaitu air, dalam upacara ini juga melibatkan komponen hayati lainnya yaitu tumbuhan. Tumbuhan berupa hasil alam dari pertanian warga Desa Penanggal seperti sayur-sayuran, buah-buahan, dan umbi-umbian lainnya yang dijadikan sebagai gunungan hasil bumi. Tujuan dari penelitian ini adalah mengkaji atau meninjau makna ritual ruwatan air di Desa Penanggal ditinjau dari pandangan ilmu etnobiologi dan menurut perspektif Islam. Jenis penelitian yaitu deksriptif kualitatif dengan menggunakan metode wawancara dalam pengumpulan datanya serta didukung dengan referensi dari jurnal untuk menguatkan hasil temuan yang diperoleh dari kegiatan wawancara. Hasil dari penelitian menunjukkan bahwa tradisi ruwatan air berkaitan dengan ilmu etnobiologi yakni dalam hubungan yang dinamis antara manusia, biota, dan alam. Begitu juga dengan perspektif Islam, tradisi ini juga memiliki amalan yang baik khususnya di Bulan Muharram yakni dengan bersedekah.

La investigación que se presenta se concentra en la plaza y jardín histórico de La Ciudadela, ubicado en la Delegación Cuauhtémoc dentro de los límites del Perímetro B del Plan Integral de Manejo del Centro Histórico del D. F. La selección de este caso de estudio por parte de los profesores de la Especialización, estableció la línea de partida y el escenario en el cual se realizaron las prácticas y diferentes aplicaciones metodológicas, a través de las cuales se profundizó el conocimiento, no sólo del sitio inmediato, sino del contexto histórico y actual de La Ciudadela, para de esta forma concretar la experiencia sensible como paisajistas y a la vez lograr dos propuestas de diseño coherentes con la historia, los usuarios y el contexto de este paisaje en particular. Formalmente, la investigación se encuentra distribuida en dos tomos: en el primero se concentra la investigación histórica vinculada al análisis de documentos, fotografías, imágenes y planos con los cuales se generó el conocimiento base sobre el sitio, a través de la suma de todos ellos en un palimpsesto. De igual forma en este tomo, se reúne la información sobre la aplicación de tres enfoques metodológicos con los cuales se evaluó, de forma consciente e integral, cada uno de los factores ecológicos, socioculturales y polisensoriales que intervienen en la conformación de esta plaza y jardín. Desde esta evaluación se generaron una serie de lineamientos seguidos a la hora de realizar cada una de las propuestas de diseño paisajístico. Asimismo, esas bases permitieron desarrollar los dos proyectos que conforman el tomo dos de esta investigación. Cada uno de ellos, con las diferencias y similitudes que albergan, representan el trabajo y conjunción de las miradas de arquitectos, biólogos, diseñadores, agrónomos y artistas, que en un esfuerzo colectivo plasmaron nuevas opciones de intervención para este espacio público. Por lo tanto, antes que nada, el espacio público es un desafío y una oportunidad para la justicia urbana. Reivindicamos la máxima calidad para el espacio público de la cotidianeidad, pero también el acceso a los espacios públicos de centralidad para todos.
Quadratic descent of generalized quadratic forms
Authors: Nokhodkar Amir Hossein
Published: May 2024

Quadratic descent of generalized quadratic forms over a division algebra with involution of the first kind in characteristic two is investigated. Using the notion of transfer, it is shown that a system of quadratic forms, associated to such a generalized quadratic form, can be used to characterize its descent properties.
Experimental validation of a dynamic lumped parameter model of an automotive cabin

Published: May 2024

The objective of this work is to propose a thermal model for predicting the average air temperature inside the passenger cabin of a small-sized car that uses an HVAC system. The adopted model is a lumped parameter model that accounts for nine heat sources acting on the cabin. Additionally, the model presents a methodology for calculating the temperature at the evaporator outlet considering a linear temperature drop between its inlet and outlet as a function of sensitive heat, latent heat, evaporator input temperature, absolute humidity, enthalpy and specific heat. Sixteen experimental tests were con-ducted on a commercial vehicle under various operating conditions to validate the presented model. The maximum average relative deviation between the experimental and theoretical results was 17.73%.
