O CRONISTA E O GEÓGRAFO: AUTOBIOGRAFIAS URBANAS AFETIVAS E SABERES NA CIDADE DE SOBRAL - CE BRASIL
Authors: Aragão Raimundo Freitas
Published: June 2024

Este artigo tem como objetivo conectar geografias autobiográficas existenciais apoiadas em formas de saberes e de afetividades. Propõe explorar saberes geográficos embasados em conhecimentos vernaculares da literatura cronista e veiculares da ciência geográfica. Neste sentido, procura evidenciar conexões entre duas autobiografias: primeiramente, a de um escritor radicado em Sobral e, em um segundo momento, a de um geógrafo nascido na mesma cidade. Dimensão afetiva da experiência do espaço, saberes geográficos vernaculares e saberes geográficos veiculares acadêmicos são termos-chaves; há fortes interconectividades entre os sujeitos em suas existências particulares, cujos significados explicam as dimensões existenciais como fatos geográficos. A metodologia debruça-se tanto sobre a interpretação existencial das imagens e das paisagens urbanas vividas quanto sobre a busca de suas essências ou de realidades espaciais as quais mais se aproximam do que se distanciam. Ressalta-se que geografia e existências estabelecidas sob saberes particulares e afetividades fazem parte da essência humana no espaço e integram a produção do conhecimento, daí a necessidade de ultrapassar limites científicos metodológicos reducionistas.

Economía y desarrollo territorial sostenible. Políticas de desarrollo territorial sostenible
Authors: Vega Núñez Jorge , Calvo González José L.
Published: June 2024

En este libro nos planteamos un reto y una propuesta: el reto es la reactivación sostenible de la España Despoblada, compuesta por territorios con graves problemas de despoblación, envejecimiento y desequilibrio económico; la propuesta, que para hacer frente con éxito a esta problemática se requiere un ecosistema de colaboración, innovación y emprendimiento que consensue un modelo socioeconómico adecuado para la reactivación sostenible. Dicho ecosistema se ha venido desarrollando en el Consorcio UNED de la provincia de León arrojando resultados positivos que se pueden resumir a modo de decálogo para el desarrollo territorial sostenible: • La Investigación, a través de un análisis y diagnóstico inicial que parte de hipótesis y premisas adecuadas al reto planteado y se basan en una visión que supera la de la Teoría Económica ortodoxa. • La Transferencia, con una «escucha activa» que trata de dar soluciones operativas a los problemas del territorio. • La Gobernanza, vía un ecosistema de innovación colaborativa con un modelo mixto de gestión. • La Tecnología, en base a plataformas interoperables basadas en estándares que facilitan el trabajo colaborativo y la producción de contenidos digitales. • La Oportunidad de la visión europea a través de los Fondos “Next Generation” • El Emprendimiento de base social y tecnológica a través de un único Centro de Innovación Territorial que trata de evitar duplicidades y despilfarro de recursos públicos. • Los Prototipos, que ofrecen respuestas ágiles basándose en una innovación abierta y multidisciplinar. • El Patrimonio, a través de una puesta en valor de los recursos que aprovecha las potencialidades de las industrias creativas y culturales. • El Catalizador del turismo sostenible e inteligente que aprovecha las capacidadestecnológicas y colaborativas del ecosistema para ofrecer «productos integrales que ponen en valor el territorio». • La Medición de Resultados, en base al modelo de retorno social de la inversión que, de forma fácil de comprender por el ecosistema, permite retroalimentar los procesos promoviendo la mejora continua.
Entender la democracia
Authors: Rebollo Delgado Lucrecio
Published: June 2024

Este trabajo tiene como misión primordial mostrar cómo se configura nuestro sistema básico de ordenación social en la actualidad, de dónde surge, cómo funciona, y cuáles son sus debilidades, y singularmente, cuáles pueden ser las circunstancias para su deterioro o desaparición. Se tiende con frecuencia a atribuir los grandes avances de la civilización a cuestiones tan concretas como la revolución industrial, el desarrollo de la tecnología, Internet, la expansión de la educación y la cultura, la sanidad, la ciencia, y a otros aspectos de la vida del hombre. Pero se obvia que todos ellos han sido posibles en un contexto social, en unas condiciones favorables, que esencialmente se dan en las denominadas democracias liberales, y que se concretan en la forma de vida de los individuos, y en los grupos en que se integra. El objetivo de esta obra es hacer relato divulgativo de aquello sobre lo que tenemos ya una larga perspectiva histórica y que posee una complejidad intrínseca, la organización social. Donde es fácil confundir las causas con las consecuencias, los objetivos con los fracasos, y todo ello sumido en una constante niebla ideológica, que en la mayoría de las ocasiones hace inviable obtener una visión objetiva, nítida, que sea útil para el futuro. El camino que debemos tomar es indefectiblemente unidireccional, no podemos prescindir de la organización estatal, y tampoco de un modo eficaz de ejercer el poder. La fórmula más avanzada que conocemos para conseguir estos objetivos es el Estado social y democrático de Derecho. Si tenemos en cuenta que la organización social y la voluntad política se canalizan hoy a través del partido político, y que todo ello se garantiza con el reconocimiento en un texto normativo, de aplicabilidad directa y rango jerárquico superior que es expresión de la voluntad popular, y al que denominamos constitución, tendremos identificados los elementos esenciales que entran en juego, y a partir del análisis de todos ellos, podremos obtener claras conclusiones. Estamos afortunadamente condenados a conservar estos logros, e inexorablemente obligados a perfeccionar su conformación y su funcionamiento. El Estado es hoy el soporte institucional de nuestro modelo de democracia, y la constitución es elemento de garantía de su existencia. Estado, constitución y democracia son tres elementos directamente interrelacionados y con una dependencia mutua, en la que el partido político es el elemento básico de ensamblaje y funcionamiento. Es a partir de lo que tenemos desde donde hemos de adecuar o transformar nuestro sistema de organización social. Si como manifestara Aristóteles, la felicidad es “el fin supremo de nuestras actuaciones”, para alcanzarla, tanto a nivel individual, como colectivo, no parece existir alternativa, debemos canalizar estas a través del Estado social y democrático de Derecho, para lo que es requisito esencial conocerlo, en definitiva, entender la democracia.

An approach to metric space-valued Sobolev maps via weak* derivatives
Authors: Creutz Paul , Evseev Nikita
Published: June 2024

We give a characterization of metric space-valued Sobolev maps in terms of weak* derivatives. More precisely, we show that Sobolev maps with values in dual-to-separable Banach spaces can be defined in terms of classical weak derivatives in a weak* sense. Since every separable metric space

can be characterized by postcomposition with such embedding and the mentioned weak gradients. A slight variation on our definition was proposed previously by Hajłasz and Tyson. However, we show that their definition does not work in the sense that for technical reasons the arising Sobolev space is essentially empty.

Authors: Alabdulaziz Mansour Saleh , Alhammadi Ali Abdullah
Published: June 2024

The objective of this research is to examine the impact of the Madrasati platform experience on acquiring mathematical concepts, and improving learning motivation from the point of view of mathematics teachers. To achieve the objective of the research, the researchers relied on the descriptive approach in its survey style. The sample of the study consisted of 613 mathematics teachers in the Kingdom of Saudi Arabia, and the study tool (questionnaire) was distributed to them. These data were processed through the use of quantitative methods and measures, such as the statistical packages program SPSS. The main results were as follows. First, there was a moderate level of agreement among participants regarding the impact of the experience of using the Madrasati platform. Second, there was a much stronger level of agreement regarding the degree to which using the Madrasati platform enabled students to acquire mathematical concepts. Third, there was almost universal agreement among participants that using the platform enhanced students’ motivation to learn. Fourthly, the participants perceived there to be an extremely strong relationship between enhanced motivation to learn and the acquisition of mathematical concepts. The researchers recommend that students and mathematics teachers should continue to use the Madrasati platform in the everyday school environment.
Development of clinical decision-making among undergraduate nursing students: the effect of unfolding case-based learning
Authors: Liu Wei
Published: June 2024

Objectives

This prospective cohort study evaluated the effect of unfolding case-based learning on undergraduate nursing students’ self-perceived clinical decision-making ability.

Methods

Students’ self-reported responses to Jenkins’s Clinical Decision Making in Nursing Scale were compared between the unfolding case-based learning cohort (n=140) and the comparison cohort (n=126) at a school of nursing in the United States.

Results

The results revealed similar students’ responses between the two study cohorts. However, unfolding case-based learning significantly increased students’ perceived proficiency in “search for information and unbiased assimilation of new information”.

Conclusions

Findings from the present study highlight possibilities presented by unfolding case-based learning in undergraduate nursing education. The study supports that unfolding case studies can be introduced early on, and then nurtured throughout the undergraduate program to influence the development of nursing students’ clinical decision-making skills.
Discrete Morse theory segmentation on high-resolution 3D lithic artifacts
Authors: Bullenkamp Jan Philipp , Kaiser Theresa , Linsel Florian , Krömker Susanne , Mara Hubert
Published: June 2024

Motivated by the question of understanding the roots of tool making by anatomically modern humans and coexisting Neanderthals in the Paleolithic, a number of shape classification methods have been tested on photographs and drawings of stone tools. Since drawings contain interpretation and photographs fool both human and computational methods by color and shadows on the surface, we propose an approach using 3D datasets as best means for analyzing shape, and rely on first open access repositories on lithic tools. The goal is to not only analyze shape on an artifact level, but allow a more detailed analysis of stone tools on a scar and ridge level. A Morse-Smale complex (MS complex) extracted from the triangular mesh of a 3D model is a reduced skeleton consisting of linked lines on the mesh. Discrete Morse theory makes it possible to obtain such a MS complex from a scalar function. Thus, we begin with Multi-Scale Integral Invariant filtering on the meshes of lithic artifacts, which provides curvature measures for ridges, which are convex, and scars, which are concave. The resulting values on the vertices can be used as our discrete Morse function and the skeleton we get is build up from lines that will coincide with the ridges and, implicitly, contains the scars as enclosed regions of those lines on the mesh. As this requires a few parameters, we provide a graphical user interface (GUI) to allow altering the predefined parameters to quickly find a good result. In addition, a stone tool may have areas that do not belong to the scar/ridge class. These can be masked and we use conforming MS complexes to ensure that the skeleton keeps these areas whole. Finally, results are shown on real and open access datasets. The source code and manually annotated ground truth for the evaluation are provided as Open Access with a Creative Commons license.
Environmental Nonprofit Organizations and Public Opinion on Global Warming
Authors: Sun Yu
Published: June 2024

Environmental nonprofit organizations (ENPOs) play a critical role in climate governance. Though ENPOs dedicate significant efforts to advocacy and providing public services, their interaction with public opinion on global warming has not been fully explored. Through multilevel regression analysis on county-level data in the U.S., this article examines the relationship between the presence of ENPOs and public perceptions of global warming, taking into account variations among ENPOs. The findings indicate that: (1) the overall presence of ENPOs is slightly, but not significantly, positively correlated with public perceptions of global warming, with advocacy-oriented ENPOs showing a more robust and statistically significant correlation; (2) there is an inverted-U relationship between the presence of ENPOs and public opinion on global warming, with advocacy-oriented ENPOs reaching tipping points earlier than service-oriented ENPOs; and (3) the partisanship of liberal counties influences this association. This study suggests a potential role for nonprofits in policymaking by interacting with public opinion.
Who Volunteers at Refugee and Immigrant Nonprofits? Results from Two Studies
Authors: Ferris Anna , Marrese Tiana , Cnaan Ram , Choi Daniel , Handy Femida
Published: June 2024

Refugee and immigrant nonprofit organizations rely on their volunteers to carry out services that are critical for supporting their mission. The primary aim of this paper is to explore the types of volunteers who support refugee and immigrant nonprofits. We report findings from two independent, but complementary studies. Study 1 examined the individuals who formally volunteered before and during the COVID-19 pandemic at refugee and immigrant nonprofit organizations. In our analysis, we employed a logistic regression to understand to what extent volunteering at refugee and immigrant organizations is associated with demographic characteristics, religiosity, political views, and civic engagement. We compare volunteers assisting refugees and immigrants to volunteers serving other causes and all individuals who volunteer in the US. In Study 2, we aimed to know individuals volunteering for refugees and immigrants more deeply and conducted 15 in-depth semi-structured interviews with volunteers who supported Afghan evacuees between August 2021 and August 2022 through a refugee resettlement organization or a community sponsorship group. Findings from Study 1 indicate that volunteers supporting refugees and immigrants are more likely to be part-time workers, born outside of the US, are more liberal in their political views, and are more likely to be religious than volunteers who serve other organizations. Results from Study 2 show that volunteers were not new to volunteering for refugee and immigrant causes, were often motivated by personal or family experiences with migration or displacement and were affiliated with a congregation or synagogue. Volunteers showed that they went beyond traditional resettlement support that focused on providing immediate needs and were also active in political advocacy for refugees and immigrants. We conclude by providing exploratory insight into the individuals that support refugee and immigrant nonprofits and we offer practice implications relating to sustaining this unique group of volunteers.
The Russian Federal Assembly as a Producer of Legal Restrictions, 2012–2021
Authors: Flikke Geir
Published: June 2024

This article discusses the role of the Russian Federal Assembly in legislating containment of the 2011/2012 domestic protests, the increased contentious politics that followed with the 2018 Navalny campaign, and the 2019 Golunov and Moscow City Council electoral demonstrations. It scrutinizes the evolution of restrictive legislation from 2012 to 2021 and finds that, after the protests of 2011/2012 the Federal Assembly has played an ever more important role in redesigning legislation that undercut the liberal framework of the 1993 Constitution. The study contributes to understanding the role of legislatures in post-Soviet patrimonial regimes; and it discusses how Russia’s patrimonial legislatures respond to popular protest and contentious politics by restructuring societal expectations and enhancing the regime’s coercive capacity, cementing it in personalized authoritarianism.

Pheochromocytoma (PCC) and abdominal paraganglioma (aPGL) (together abbreviated PPGL) frequently present with an underlying genetic event in a PPGL driver gene, and additional susceptibility genes are anticipated. Here, we re-analyzed whole-exome sequencing data for PCC patients and identified two patients with rare missense variants in the calcium voltage-gated channel subunit 1H gene (CACNA1H). CACNA1H variants were also found in the clinical setting in PCC patients using targeted sequencing and from analysis of The Cancer Genome Atlas database. In total, CACNA1H variants were found in six PCC cases. Three of these were constitutional, and two are known to have functional consequences on hormone production and gene expression in primary aldosteronism and aldosterone-producing adrenocortical adenoma. In general, PPGL exhibited reduced CACNA1H mRNA expression as compared to normal adrenal. Immunohistochemistry showed strong CACNA1H (CaV3.2) staining in adrenal medulla while PPGL typically had weak or negative staining. Reduced CACNA1H gene expression was especially pronounced in PCC compared to aPGL and in PPGL with cluster 2 kinase signaling phenotype. Furthermore, CACNA1H levels correlated with HIF1A and HIF2A. Moreover, TCGA data revealed a correlation between CACNA1H methylation density and gene expression. Expression of rCacna1h in PC12 cells induced differential protein expression profiles, determined by mass spectrometry, as well as a shift in the membrane potential where maximum calcium currents were observed, as determined by electrophysiology. The findings suggest the involvement of CACNA1H/CaV3.2 in pheochromocytoma development and establish a potential link between the etiology of adrenomedullary and adrenocortical tumor development.
Onde reside o ódio no discurso de ódio "suave": O potencial argumentativo em esferas públicas hostis
Authors: Mohammed Dima
Published: June 2024

Neste artigo, exploro a discriminação por ódio envolvida em mensagens públicas, em que um político português alega actos ilícitos cometidos por membros da comunidade cigana. As mensagens, que levaram a uma acusação de discurso de ódio contra o político, mas que não conduziram à sua condenação, são analisadas como casos de discurso de ódio suave (Assimakopoulos et al., 2017): embora não indiquem necesariamente, de forma explícita, que alguém deve ser odiado,  fornecem de forma crucial a lógica subjacente ao ódio discriminatório. De modo a identificar esta lógica subjacente, discuto as premissas que são comunicadas nas mensagens e reconstruo o argumento global que as liga, com especial atenção ao potencial argumentativo (Mohammed, 2019; ver também Kjeldsen, 2017; Serafis, 2022). A análise revela um significado implícito que não é apenas discriminatório, mas que também incita ações que podem eventualmente resultar em violência contra a comunidade cigana. Consequentemente, explica-se o que torna o discurso de ódio suave, perigoso: embora as mensagens não sejam necessariamente culpáveis do ponto de vista jurídico, são, no entanto, discursivamente responsáveis, por incitarem ao ódio, à discriminação e - talvez - à violência contra um grupo minoritário, já de si, desfavorecido.

Published: June 2024

Identificar iniciativas educativas de comunidades rurales, en las cuales se reconozca el contexto y sus necesidades, puede llegar a ser una de las alternativas que aporten al Plan Especial de Educación Rural contemplado en el punto 1 del acuerdo de paz. Este artículo buscó comprender la función de la praxis (reflexión y acción), en el programa educativo la Guardia del Monte (GM), desarrollado por la comunidad de firmantes de paz en Caquetá, Colombia del A-ETCR del Centro Poblado Héctor Ramírez. Este programa hace parte del proyecto Educación, Campo y Reconciliación (EDUCARE), el cual busca fortalecer la educación de la comunidad. Para comprender el rol de la praxis en el desarrollo del programa, se realizó un análisis temático de documentos como la planeación educativa, grabaciones de procesos reflexivos y productos audiovisuales de las actividades en GM. Los principales hallazgos de esta investigación permiten identificar que la praxis en el programa de GM, funciona por medio de la creación de espacios dialógicos en los cuales, profesoras, niños niñas y jóvenes reflexionan de manera crítica y colectiva sobre los principios, valores, prácticas y saberes para la preservación de la identidad étnica y campesina para el Buen Vivir de la comunidad.
Colon Cancer Genetic and Epigenetic Changes, Etiopathogenesis, Risk Factors, Treatment: Literature Review
Authors: Ūbaitė Gabrielė , Remeikaitė Aurelija , Žilinskas Justas
Published: June 2024

Background. Colorectal cancer (CRC) ranks as the third leading cause of cancerrelated mortality worldwide. Recent years have witnessed an increase in the incidence of CRC. The main reasons are ageing population, increased consumption of processed food, obesity, genetic predispositions. Aim. To review the latest scientific developments and novel factors on the epidemiology, etiology, pathoge­nesis of colon cancer, focusing on the influence of genetics and epigenetics, risk factors, and the advancement of prevention and treatment methods. Material and methods. The research method is a literature review. Publications were searched in the PubMed database using the following keywords and their combinations in English: colon cancer, colorectal cancer, management, prevalence, causes, risk factors, genetic and epigenetic changes. Selection criteria for publications: scientific articles in English relevant to the research topic and 90% of articles published in the last 10 years (2014–2024). Results. Using theoretical analysis methods, 72 publications were selected that met the inclusion criteria. Our findings emphasize the central role of genetic mutations (particularly in APC, TP53, KRAS and MMR) and epigenetic alterations, such as DNA methylation and histone modification, in the pathogenesis of colorectal cancer. These genetic and epigenetic factors drive the progression from benign polyps to malignant carcinomas, with environmental, lifestyle, and chronic disease factors also playing a critical role. In particular, diet, physical inactivity, smoking and alcohol significantly increase risk, especially in men and those over 50. Innovations such as CRISPR/Cas9 offer new avenues for targeted treatments, while advances in vaccines and liquid biopsy techniques are improving immune response activation and disease monitoring. In addition, diets rich in fiber, antioxidants and healthy fats, as well as the use of probiotics and NSAIDs, are key to reducing cancer risk through their anti-inflammatory effects and promoting gut health. Conclussions. This review highlights the significant impact of genetic and epigenetic factors on colorectal cancer (CRC) development, in addition to the role of lifestyle and environmental exposures. It highlights the potential of CRISPR/Cas9, immunotherapies, and liquid biopsies in pioneering personalized CRC treatments and early detection. Advances in prevention and technology promise a new era of personalized, effective CRC management strategies.
Iššūkiai politinės reprezentacijos raiškai didžiųjų duomenų laikais
Authors: Eidikytė Kristina
Published: June 2024

This article deals with the problem of the change in the theoretical conception and practical realisation of political representation in the era of big data, i.e. in the 20th and 21st century, when IT data processes have become an almost integral part of the political life of citizens. Based on the concepts of the philosophers F. Ankersmit and J. Baudrillard, the article analyses why, despite the arguments of critical data studies, the forms of political representation affected by big data are still considered objective. After presenting research on the characteristics of political representation in the information technology-dominated public sphere and smart cities, the article identifies signs of the decline of contemporary political representation: the compression of public space and the legitimation processes of datafication facilitated by big data in the smart city. The continuation of the article’s theme and the analysis of the problems are recommended to be pursued in the field of post-political discussions.

Published: June 2024

Los saberes ecológicos tradicionales cobran relevancia como alternativa para la conservación de la diversidad biológica. El objetivo fue identificar los procesos de generación de conocimiento ambiental de mujeres y hombres para el cultivo, recolección y venta de frutos, en San Andrés Nicolás Bravo, Malinalco. Se llevó a cabo un estudio de caso mediante el método etnográfico: entrevistas de enero de 2019 a febrero de 2020 y observación directa para identificar usos, cultivo y recolección de especies frutales en el tianguis de Malinalco, se registraron las actividades de hombres y mujeres para la venta de frutos. Las especies frutales se identificaron botánicamente. Se registraron 59 frutos comestibles, de los cuales 18 están en los huertos familiares, trece en la selva baja caducifolia y 28 en ambos espacios. Estos se clasificaron de acuerdo al lugar y forma de producción y recolección, pero también de acuerdo al manejo que la población le da para la venta; en todos estos procesos se identificaron diferentes conocimientos. Los procesos de generación de conocimientos ambientales de hombres y mujeres sobre los frutos se relacionan con las actividades designadas por género y responsabilidades de acuerdo con la edad y roles dentro de la familia y los espacios de producción donde se realizan la siembra, plantación, cultivo, cosecha, manejo postcosecha y venta de frutos.
The release call of Dendropsophus sanborni (Anura: Hylidae), with comments on release calls within Dendropsophus

Published: June 2024

Release calls are a non-receptive response to amplexus between different species or conspecific amplexus between males. This call differs between closely related species and can be an important tool for the taxonomy of this group. Here, we describe, for the first time, the release call of Dendropsophus sanborni (Schmidt, 1944) from a record during a field trip in a palm grove in southern Brazil. We recorded two release calls from a male individual of D. sanborni while handling it. These release calls are simply formed by one note with no modulation. Release calls of Dendropsophus are poorly reported in the literature, and comparisons among them are limited. Release calls are possibly much more common than reported in the literature and more description studies are needed.
A theoretical framework to study accumulation regimes and crises in Colombia
Authors: Mahecha Alzate Manuela
Published: June 2024

The neorealist approach to institutional change has the merits of emphasising the importance of the Dominant Social Bloc (DSB) in institutions, and of integrating economics, society, and politics in the formation and breakdown of the DSB. Since this approach was not designed for Colombia, it is necessary to integrate certain characteristics, such as economic dependence, armed conflict, and drug trafficking. This paper presents the first theoretical adaptation of the neorealist approach for a Latin American country. This extended theoretical framework evinces the role of crime and violence in providing political stability to an accumulation regime that satisfies the demands of a narrow DSB.
Salteadores y bandidos en tiempos de la Anarquía Militar. Anomia política, caos económico y auge criminal en el sur peruano a inicios de la República (1824-1845).
Authors: Belan César Augusto
Published: June 2024

En el presente artículo se busca analizar la incidencia criminal en el sur peruano en los primeros años de la República, comparándola además con la etapa anterior tardovirreinal. El estudio se ubica en los departamentos del sur del Perú, fundamentalmente en Arequipa. Se han utilizado como fuente primaria más de mil expedientes de causas criminales del fondo Corte Superior de Justicia del Archivo Regional de Arequipa. Para su formulación se han utilizado los postulados teóricos de la escuela funcionalista de Durkheim y las ideas de Ranajit Guha para ensayar algunas explicaciones sobre la magnitud delictiva en relación con el contexto. En este se ha identificado la relación entre la debilidad institucional de la temprana República, y, sobre todo, la crisis económica acaecida en el contexto de las guerras civiles y la anarquía militar de inicios de la República peruana y el auge entre los ataques a la propiedad, especialmente en formas como el bandolerismo y el abigeato.
Thermal Degradation Analysis of Mamoncillo (Melicoccus bijugatus) Waste: Thermal Behaviors, Kinetics, and Thermodynamics
Authors: Rojas-González Andrés Felipe , Velasco-Sarria Francisco Javier
Published: June 2024

This research studied the thermal conversion characteristics, kinetics, and thermodynamics of mamoncillo peels and seeds using non-isothermal thermogravimetric analysis. Kinetic analysis was performed using the Kissinger-Akahira-Sunose, Flynn-Wall-Ozawa, Starink, and Friedman methods. The reaction kinetic models were obtained by means of the master-plots method for 18 different empirical reaction models, calculating the enthalpy, Gibbs free energy, and entropy as thermodynamics parameters. It was found that the average activation energy for mamoncillo peels and seeds was 238,71 and 197,60 kJ/mol, respectively. The frequency factor was found to be between 109 and 1031 s-1 for mamoncillo peels and between 109 and 1034 s-1 for mamoncillo seeds. The average values of DH and DG were also found to be 233,83 and 192,81 kJ/mol and 164,84 and 162,10 kJ/mol for mamoncillo peels and seeds, respectively. The reaction kinetic models regarding the thermal decomposition of mamoncillo peels were found to be described by the contracting cylinder (R2) and third-order (F3) models, while those for mamoncillo seeds can be described by the second-order (F2) and contracting sphere (R3) models. It was concluded that the pyrolysis process of mamoncillo waste can be described by a complex reaction mechanism, and that these wastes have thermal properties with the potential to produce bioenergy.
Numerical Assessment of Bidirectional Roller Bearing Isolators under Near-Fault Earthquakes
Authors: González-Olaya Ricardo , Ortiz-Cano Nelson Andrés , Gaviria-Mendoza Carlos Andrés , Magluta Carlos , Roitman Ney
Published: June 2024

In this research, a bidirectional seismic isolation device composed of sloped bearing plates and multiple rollers arranged in both orthogonal-in-plane directions is numerically studied. A previous analytical model of a single direction of roller bearing (RB) system is extended to a two-direction RB system. Several experimental tests in a physical building model with and without an RB system are used to validate the numerical model. The model is used to perform the nonlinear response of a four-story multi-column building when subjected to pairs of scaled near-fault earthquake records. The effect of the inclination angle of bearing plates in the range of 1.0° to 4.0°, the sliding friction force, and supplementary damping mechanisms ranging from 0.0 to 0.5 N/kg (i.e. friction force normalized with the structure mass) are also investigated. The results show that the proposed bidirectional RB system is suitable for reducing the seismic response of stiff and flexible multi-column structures. In particular, the RB system reduces the acceleration responses by 5% to 85% in flexible structures and 86% to 96% in stiff structures. Furthermore, bearing plates with an inclination angle greater than or equal to 3.0° have significant benefits in terms of self-centering capacity.

Authors: González-Barbosa Erick Alejandro , Vázquez-Martínez José Juan , Jurado-Pérez Fernando , Castro-Mosqueda Héctor , Rodríguez-Ornelas Francisco Javier , González-Barbosa José-Joel
Published: June 2024

In the modern industry, computer modeling and simulation tools have become fundamental to estimating the behavior of rotodynamic systems. These computational tools allow analyzing possible modifications as well as alternative solutions to changes in design, with the aim of improving performance. Nowadays, rotodynamic systems, present in various industrial applications, require greater efficiency and reliability. Although there are deep learning methodologies for monitoring and diagnosing failures which improve these standards, the main challenge is the lack of databases for learning, a problem that can be addressed through experimental monitoring and computer analysis. This work analyzes the vibrations of two induced-draft fans with excess vibration in a thermoelectric plant in Mexico. A vibration analysis was carried out through the instrumentation and monitoring of accelerometers located at crucial points in the fans. The results of this experimental analysis were validated by computer simulation based on FEM. The results show that the operating speed of the induced-draft fans is very close to their natural frequency, causing considerable stress and potential failures due to excessive vibration. Finally, this work presents a practical solution to modify the natural frequency of induced-draft fans, so that they can function correctly at the required operating speed, thus mitigating excessive vibration issues.

On medical education in Latin America
Authors: Hernández-Yasnó Marcelo Andrés
Published: June 2024

Although the World Medical Association has established the minimum quality standards for the training of general practitioners in order for them to acquire the basic medical competencies necessary to practice their profession properly, it is also important to remember that there are psychosocial aspects that influence the training processes of medical students. In this sense, the social responsibility of Latin American medical schools to train competent physicians in order to contribute to the reduction of inequalities in the region has been included in recent decades as a standard of quality in medical education.
Mothers' memories: an approach to maternal mental health
Authors: Paricio-del Castillo Rocío
Published: June 2024

Psychological distress in women who are mothers is a serious public health concern that greatly affects the physical, social, and emotional development of their babies. Often, mothers with mental health issues do not receive the care they require, not only because of the persistent social stigma associated with mental illness, but also due to a lack of resources.
From the perspective of our perinatal and child-rearing psychiatry practice, and based on the available literature, we reflect on the care received by those women, who are now mothers, during their own childhoods and its impact on how they currently experience motherhood.
Early attachments have a deep impact on both memory and behavior throughout our lifetimes. When they become mothers, women may update their own childcare experiences, a phenomenon known as “psychic transparency” and mobilize the lessons they received as infants about relationships, care, and emotional regulation. The anxiety and frustration faced by mothers today seem to arise, partially, from the conflict between the parenting style they want to offer their babies (warm and conscious) and the one they received at a time when prevailing theories discouraged breastfeeding and skin-to-skin contact.
Taking care of mothers’ emotional states and supporting their relationship with their babies is a necessary and urgent public health measure, which has intergenerational repercussions in mental health.

A new subgenus Chrysolina (Ambrostomima Subgen. Nov.) (Coleoptera: Chrysomelidae: Chrysomelinae) from Hengduan Mountains, China
Authors: Bieńkowski Andrzej O.
Published: June 2024

A new subgenus of leaf-beetles Chrysolina (Ambrostomima subgen. nov.) is described from Hengduan Mountains (Sichuan and Gansu, China). It is characterized by the following main characters: body metallic, mostly green mixed with purple or one-colored green; last maxillary palpomere elongate, narrow, similar in both sexes; elytral punctures arranged in more or less distinct rows or mostly irregular; elytral epipleura inclined outside; hind wings completely missing; pygidium without furrow in apical 1/2 in most species; tarsomeres 1–3 more or less broadened in male, narrow in female, with entire sole in both sexes.

The subgenus consists of 25 species: Chrysolina amica Lopatin, Ch. baimana Lopatin, Ch. davidiani Lopatin, Ch. korotjaevi Lopatin, Ch. luyoui Daccordi et Ge, Ch. matruelis Lopatin, Ch. mirabilis (Daccordi), Ch. nesterovae Lopatin, Ch. pingchuana Lopatin, Ch. purpureoviridis Lopatin, Ch. rotundata Lopatin, Ch. sichuanica Lopatin, Ch. sicieni Ge et Yang, Ch. songpana Lopatin, Ch. viridiopaca Lopatin, Ch. aurita sp. nov., Ch. auriviridis sp. nov., Ch. bellissima sp. nov., Ch. ferdinandoi sp. nov., Ch. korolevi sp. nov., Ch. latipes sp. nov., Ch. ovata sp. nov., Ch. pilula sp. nov., Ch. pulchra sp. nov., and Ch. tortilla sp. nov.

Types of all previously described species except Ch. luyoui are examined. Males of Ch. mirabilis and Ch. viridiopaca are examined and described for the first time. Key to species is compiled. Type localities of Ch. viridiopaca and Ch. songpana are corrected. Photographs of habitus and male aedeagi are presented for all species.
‘Yoga Helps!?’
Authors: Augspurger Jens U
Published: June 2024

This paper explores the role of health discourse from yoga providers and biomedical research in popularising transglobal yoga and legitimizing claims about its health benefits. As contemporary yoga is more widely associated with physical and mental health benefits, it is frequently positioned as an antidote to the many perceived ailments of modern life. My analysis of discourses surrounding yoga’s effectiveness reveals a serious epistemological lacuna: I argue that biomedical impact studies on yoga often fall short in deconstructing the unique contributions of yoga as a practice and its historic origins. Consequently, contemporary yoga modalities are often presented as a several thousand years old tradition to achieving good health. These oversights inadvertently perpetuate an uncritical assertion of yoga’s distinct originality, providing potential legitimacy to extravagant health claims and unwarranted generalizations mistakenly attributed to the entire spectrum of ‘yoga’. The resulting positive perception of yoga poses a potential hazard to practitioners and is at risk of being misused as a vehicle for dubious political or financial gains. I conclude with considerations on how future research on yoga’s effectiveness could intend to understand not only if yoga practice is beneficial to health, but also which aspects of it, and how.
Cyclometalated platinum(II) complexes bearing eugenol as effective catalyst for hydrosilylation of phenylacetylene by triethoxysilane

Published: June 2024

The catalytic activities of the platinacyclic complexes bearing eugenol (EugH) including [Pt(μ-Cl)(Eug)]2 (1) and [PtCl(Eug)(amine)] (2–4) [amine: pyridine/2, 4-methylpyridine/3, quinoline/4] for hydrosilylation of phenylacetylene by triethoxysilane have been studied for the first time. The results showed that the complexes 1–4 exhibited good catalytic abilities. With loading 0.5 mol% each of the catalysts 1–4 at 70 oC without solvents and any other additives in the air for 2 hours, the triethoxysilane was completely converted to (E)-triethoxy(styryl)silane) (β(E) – the major product) and (triethoxy(1-phenylvinyl)silane) (α – the minor product) with the α/β(E) molar ratio ranging from 1 : 2.6 to 1 : 2.8. At the same reaction conditions with loading 0.1 mol% each of the catalysts 2–4, the conversion of triethoxysilane slightly reduced with an efficiency of 97–99% and the α/β(E) molar ratio of 1 : 2.6 indicating the important role of the Pt-(C=Calkene) in 1–4 for their catalytic activity. Furthermore, the verification of structures of complexes 2–4 by 13C NMR spectroscopy indicated that in chloroform-d1, complex 3 formed two distinct structural forms due to strong intermolecular interactions between the chloroform solvent and the complex, including a Cl3C-H...ClPt(II) hydrogen bond and a Cl2HC-Cl...Pt(II) halogen bond.

Following the end of second World War, 48 percent area of the Second Polish Republic was incorporated into the Union of Soviet Socialist Republic. A significant number of Polish citizens remained in the annexed areas and along with them their pastors. As for members of the Society of St. Francis de Sales (Salesians), ten remained in the areas incorporated into the USSR, who helped organize the religious life of the faithful under very difficult circumstances. They maintained contact with the religious congregation in Poland, mostly it was limited to correspondence and short visits on the occasion of family visits to Poland. The source presents notes from the stay in the USSR of Fr. Stanisław Rokita SDB, who in 1973 was the first Salesian superior to visit his congregation remaining in the East.
