O que nos dizem as lutas indígenas, em sua longa duração? O texto se inicia pela crise climática, advertência já antiga de cientistas indígenas, e depois estuda as cosmopolíticas (já que não opera a rígida divisão entre natureza e cultura), resistências de humanos e não humanos contra a destruição dos mundos socioambientais. Em seguida, o artigo analisa como essas características fundamentais ameríndias permitem fazer aflorar uma linhagem menor da tradição revolucionária (com sua agência de espíritos e espectros) e conclui sua explanação com relatos de sobrevivência, vitais para nossos tempos.

Antecedentes: Las exposiciones accidentales son las causas más comunes de intoxicación, y representan hasta en un 70% de los casos, especialmente en la edad pediátrica. Sin embargo, existe un subregistro de estos eventos en el territorio colombiano.
Objetivo: Describir los reportes de intoxicación pediátrica informados por los medios de comunicación en Colombia durante el periodo 2011-2022.
Metodología: Se realizo una búsqueda de reportes de intoxicación pediátrica publicados por los medios de comunicación vía internet (sitio web y/o redes sociales) y/o medios físicos (revistas, periódicos y redes sociales), publicados entre los años 2011 y 2022. Se emplearon para la búsqueda las palabras claves: intoxicación, envenenamiento, pediatría, niños, Colombia, hogar, animales ponzoñosos, sustancias químicas, productos del hogar y gases, las cuales se combinaron con el operador Booleano Y. Todos los datos extraídos se condesaron en un base de datos y posteriormente analizados mediante estadística descriptiva.
Resultados: Se encontró un total de 285 casos de intoxicación en población pediátrica reportados durante el periodo de la búsqueda. Estos se distribuyeon en la región Caribe, Andina, Pacífica, Orinoquía y Amazonia. Los agentes causantes de estas intoxicaciones fueron animales ponzoñosos (serpientes, ciempiés, alacranes y abejas) y gases (monóxido de carbono). Hubo reporte de 41 muertes de menores tras la exposición a estos agentes etiológicos.
Conclusión: Las intoxicaciones pediátricas son un tema importante para los sistemas de salud y para la comunidad en si, ante el subregistro existente de estos eventos, se quiere llamar la atención para crear estrategias comunitarias y a nivel de salud pública para que estos hechos evitables disminuyan.

Authors: Gualdron Juan pablo , García Suárez Ana María , Alfaro Castro Mariela de Jesús , Ibañez blanco Fiorella minelis , Tirado Perez Irina Suley
Published: January 2025

Antecedentes: El síndrome de CLOVES es un nuevo síndrome de sobrecrecimiento segmentario en mosaico esporádico, actualmente clasificado bajo el dosel de trastornos PROS (espectro de sobrecrecimiento relacionado con PIK3CA). El crecimiento excesivo es segmentario, irregular, asimétrico y se limita a las partes del cuerpo afectadas por la mutación.
Reporte de caso: Adolescente con cuadro clínico caracterizado por sobrecrecimiento lipomatoso desde la infancia, en todo el cuerpo, de predominio en tórax, por lo cual recibió varias intervenciones quirúrgicas además de manejo con quimioterapia, actualmente en manejo interdisciplinario.
Conclusión: El síndrome de CLOVES, es una entidad rara, de difícil manejo. No existe una cura específica. Hasta hace poco, los pacientes con síndrome de CLOVES eran tratados únicamente de forma paliativa mediante cirugías cito reductoras multidisciplinarias y escalonadas para sobrecrecimientos lipomatosos y esqueléticos, sin embargo, los avances en el diagnóstico molecular han mostrado aporte, utilizándose nuevos medicamentos dirigidos directamente al gen PIK3CA anormal, mostrando resultados prometedores en esta entidad.

Introducción: Existe un vacío conceptual sobre la realización temprana de la confirmación genética para la Atrofia Muscular Espinal (AME). Se propone, por medio de un panel Delphi modificado, un algoritmo que oriente pragmáticamente al personal de salud, en la identificación temprana de los signos y síntomas de AME 5q tipos 1 a 3, con el fin de incrementar el rendimiento diagnóstico, clínico y molecular.
Materiales y Métodos: Utilizando Delphi modificado, tres expertos con amplia experiencia clínica, investigativa y docente desarrollaron 13 casos, teniendo como insumo una revisión descriptiva de la literatura y su experiencia asistencial. Posteriormente, un grupo extendido de nueve expertos participó en dos rondas calificativas para cada caso utilizando la escala Likert.
Resultados: Ocho expertos completaron la primera ronda, reportaron una mediana de ejercicio asistencial como especialista de 22.5 años (rango 5 a 35) y una mediana de pacientes con AME tratados de 50 (rango 15 a 150). En la primera ronda, se logró consenso en 19 afirmaciones para AME-1, 19 afirmaciones para AME-2 y 15 afirmaciones para AME-3. En la segunda ronda se logró consenso para todas las afirmaciones de examen físico y paraclínicos, mientras que las afirmaciones sin consenso se relacionaron a diagnósticos diferenciales. Hubo consenso en 72.7% de 11 afirmaciones para AME-1, en 85.7% de ocho afirmaciones para AME-2 y en 100% de ocho afirmaciones para AME-3.
Conclusiones: La metodología Delphi permitió configurar una aproximación algorítmica en forma de flujograma para la identificación temprana de los signos y síntomas y el diagnóstico de cada subtipo de AME 5q. Se propone un sustento integral y pragmático que sirva de orientación para el médico general y especialista, enfatizando en la importancia de su capacitación en la evaluación de signos y síntomas para considerar esta enfermedad tempranamente en el diagnostico diferencial.

A Bacia Hidrográfica do Rio Paraopeba, em Minas Gerais, tem sofrido com eventos climáticos extremos e os impactos do rompimento das barragens da Vale S.A. em Brumadinho, em 2019. Destaca-se a importância da análise multicritério de decisão associada a um modelo conceitual para diagnosticar a segurança hídrica na região, com base em indicadores socioambientais. O estudo propõe e analisa indicadores socioambientais, utilizando a metodologia FPEIR, para avaliar a segurança hídrica e aprimorar o planejamento e a gestão dos recursos hídricos na Bacia do Rio Paraopeba (BHRP). A abordagem combina o modelo de análise multicritério TOPSIS com o método de pesos de entropia, utilizados para hierarquizar os municípios com melhor segurança hídrica. A análise revelou desafios críticos, como crescimento populacional, industrialização e expansão agropecuária, que intensificam a contaminação hídrica. Brumadinho e Betim foram classificados como os municípios mais vulneráveis, apresentando altos índices de doenças de veiculação hídrica e infraestrutura de tratamento de esgoto insuficiente. A intensa atividade industrial e agrícola agrava os riscos ambientais, exemplificados pelo rompimento das barragens. O estudo destacou as pressões socioambientais e a importância de abordagens integradas. Os resultados apontaram a necessidade de políticas públicas robustas, práticas agrícolas sustentáveis, gestão participativa, melhoria da infraestrutura e adaptação às mudanças climáticas para garantir a segurança hídrica e a qualidade de vida.
A Short Retrospective Cytometric Note on Myeloblasts in Patients Suffering from Acute Myeloblastic Leukaemia, Myelodysplastic Syndrome and Chronic Myelocytic Leukaemia: Myeloblasts with a Narrow Cytoplasm without Azurophilic Granules Are Less Differentiated Committed Progenitor Stem Cells
Authors: Smetana Karel , Klamová Hana , Šimečková Radka , Mikulenková Dana
Published: January 2025

The maximal nuclear and cell body diameters of leukaemic agranular myeloblasts (“type 1” without azurophilic granules) were measured in bone marrow smears of patients suffering from acute myeloblastic leukaemia with minimal differentiation (M0 AML), without and with maturation (M1 and M2 AML), refractory anaemia with excess of myeloblasts (RAEB) and chronic phase of the myeloid leukaemia (CML) to provide more information on the cytoplasmic space estimate occupied by the nucleus. The largest size of the cytoplasmic space occupied by the nucleus in agranular myeloblasts was noted in M0 and M1 AML in comparison with M2 AML or RAEB, and especially with CML. Similarly, agranular myeloblasts with nuclear bodies occupying more than 90 per cent of the cell space were most frequent in M0 and M1 AML (> 50 %), less frequent in M2 and RAEB (~ 20 %) but very rare in CML (~ 5 %). According to electron microscopy, the very narrow cytoplasmic shell surrounding the nucleus in such myeloblasts did not possess any space for structural components characteristic of the granulocytic cell lineage. Thus, the basic morphology of these myeloblasts would correspond to morphological features of a less differentiated committed stem cell. It should be noted that such cells may be easily recognized in currently stained bone marrow or peripheral blood smears.

Published: January 2025

Objectives

To lessen the negative effects of the medication, we assessed the neuroprotective impact of amifostine nanoparticles against the neurotoxicity generated by cisplatin.

Methods

60 adult male albino Wistar rats were arranged into six groups. Group 1; received saline intraperitonealy (IP) and served as negative control. Group 2; received IP injection of silica nano-emulsion, Group 3 received cispatin for three consecutive days at the end of the study, Group 4 received amifostine intrapretonealy (IP) before cisplatin injection, Group 5 received silica nano-emulsion alone for one month, group 6 received silica nano-emulsion in combination with cisplatin for three consecutive days at the end of the study.

Monocyte chemoattractant protein-1 (MCP-1) and glial fibrillary acidic protein (GFAP) were estimated by ELISA, butrylcholinesterase (BChE) by spectrophotometric method while caspase-3 as a marker of apoptosis by PCR.

Results

The mean levels of brain GFAP, MCP-1, and caspase-3 in the cisplatin group were considerably higher than those in the control group. However, there was a drop in the average level of brain BChE activity. Additionally, the injection of (SiNPs@AMF + cisplatin) increased BChE activities while reducing GFAP, MCP-1, and caspase-3 levels, thereby reversing the negative effects of cisplatin on the brain tissue. On the other hand, the group treated with SiNPs@AMF + cisplatin showed improvement in overall brain structure and minimal pyknotic nuclei and apoptotic neurons were found.

Conclusions

These outcomes demonstrated amifostine’s ability to lessen the histological changes brought on by cisplatin. To sum up, SiNPs@AMF may be a suitable and secure supplemental treatment agent to lessen cisplatin’s toxicity in the brain and enhance the treatment’s effects throughout chemotherapy.
Regularization method and a posteriori error estimates for the two membranes problem
Authors: Bouchlaghem Mohammed , Mermri El Bekkaye , Mellah Zhor
Published: January 2025

This study presents a regularization method for the two membranes problem with non-homogeneous boundary conditions. We establish both convergence results and a priori estimates for this method. Using duality theory from convex analysis, we identify the dual problem related to the two membranes problem. Based on this dual formulation, we give a posteriori error estimates for both the continuous and discrete versions of the problem. These a posteriori error estimates are crucial for the practical implementation of the regularized problem.
Nanotechnology of colour: quantum dots (QDs), photonic crystals (PCs) and plasmonic nanoparticles
Authors: Das Udita , Das Ankita , Das Ruhi , Das Asim Kumar
Published: January 2025

This tutorial min review discusses the important features of nanotechnology of colour generation by the quantum dots (QDs), nanostructured photonic crystals (PCs) and plasmonic metal nanoparticles. Quantum dots (QDs) are characterized by the tunable and size dependent strong fluorescence emission properties. Photonic crystals (PCs) generate the material independent structural colour (
iridescent colour dependent on the angle of observation
) due to the constructive interference arising from Bragg diffraction by the nanostructured photonic crystals (PCs) producing the diffraction gratings. It causes the vibrant colour in the opals and pearls, wings of peacocks and butterflies, in the necks of pigeons, variable colours in chameleons, etc. Plasmonic nanoparticles like Au-, Ag- and Cu-nanoparticles show the both light absorption and scattering properties that can be tuned by varying the size, morphology and composition of the nanoparticles. Structural colour (
iridescent colour
) by PCs is used by nature while colouring by QDs and plasmonic nanoparticles are due to the man made activities. The nanotechnology based colour is superior to the organic pigment based colour in terms of brightness and photostability and this field is an emerging area of research with a great promise in terms of applications in various fields.
Stellate ganglion block in disparate treatment-resistant mental health disorders: A case series
Authors: Niraj G. , Karanth V. , Niraj S. , Charan N.
Published: January 2025

Objectives

A significant subset of patients with mental health disorders (MHDs) fail to respond to standard management and are termed as treatment-resistant. This cohort has limited options for managing their condition. Autonomic dysfunction has been reported in the neurobiology of MHDs including anxiety, depression, obsessive-compulsive disorder (OCD), panic disorder, and bipolar disorder (BD). Stellate ganglion block (SGB) is an emerging treatment that dampens sympathetic activity and has been shown to be of benefit in the management of post-traumatic stress disorder.

Methods

Patients with treatment-resistant disparate MHDs were reviewed by a multidisciplinary team comprising a psychiatrist, a clinical psychologist, and a pain medicine physician. Patients were offered SGB as a novel strategy in the management of treatment-resistant conditions. Validated outcome measures were completed at baseline, 4 weeks, and 16 weeks post-intervention.

Results

Four patients with heterogenous treatment-resistant MHDs who received SGB are presented in this report. SGB resulted in an improvement in BD, OCD with alcohol addiction, opioid addiction, and health anxiety.

Conclusion

SGB could have a role in the management of treatment-resistant MHDs.

La requalification de centres commerciaux de banlieue en Amérique du Nord : le cas de la Place Fleur de Lys à Québec
Authors: Simard Martin
Published: January 2025

À l’heure où les principes de l’urbanisme durable sont largement appliqués au Canada et aux États-Unis, les centres commerciaux de banlieue sont de plus en plus considérés par les instances publiques comme des espaces urbains sous-utilisés à réaménager. Du côté des promoteurs et des commerçants, le concept du mall perd de l’attractivité depuis une vingtaine d’années, notamment au profit du commerce électronique. Dans cet article, nous abordons la nouvelle tendance à la requalification des centres commerciaux en quartiers densifiés comprenant des espaces résidentiels, commerciaux et de bureau. Tout particulièrement, nous étudierons le cas du projet immobilier Place Fleur de Lys à Québec, où les centres d’achats de banlieue sont nombreux, en dépit de sa réputation de ville patrimoniale, ce qui offre plusieurs opportunités d’intervention ciblées en faveur d’une ville plus compacte.
L' offre territoriale, un levier d’attractivité des investissements : vers une revue systématique de la littérature
Authors: Echattabi Hicham
Published: January 2025

L’attractivité d’investissements demeure une préoccupation majeure pour les décideurs et les acteurs économiques, car elle influence les dimensions économiques, sociales et environnementales d’un territoire. L’offre territoriale constitue le pilier fondamental de cette attractivité. Cependant, dans un contexte marqué par l’apparition de nouveaux enjeux territoriaux, l’offre territoriale doit être repensée. La question de savoir comment tous les acteurs territoriaux peuvent collaborer pour coconstruire une offre territoriale diversifiée et intégrée reste un enjeu complexe et peu exploré. Cette recherche vise à combler cette lacune en proposant un recadrage théorique et un modèle conceptuel pour mieux comprendre les mécanismes de cocréation de l’offre territoriale et son impact sur l’attractivité d’investissements. En s’appuyant sur une revue de littérature systématique, cette étude apporte une clarification du concept et fait avancer la discussion autour de cette composante fondamentale du marketing territorial. Elle fournit aussi des orientations sur les principales variables de l’offre territoriale.
Mapping eye, arm, and reward information in frontal motor cortices using electrocorticography in non-human primates

Published: January 2025

Goal-directed reaches give rise to dynamic neural activity across the brain as we move our eyes and arms, and process outcomes. High spatiotemporal resolution mapping of multiple cortical areas will improve our understanding of how these neural computations are spatially and temporally distributed across the brain. In this study, we used micro-electrocorticography (µECoG) recordings in two male monkeys performing visually guided reaches to map information related to eye movements, arm movements, and receiving rewards over primary motor cortex, premotor cortex, frontal eye field, and dorsolateral pre-frontal cortex. Time-frequency and decoding analyses revealed that eye and arm movement information shifts across brain regions during a reach, likely reflecting shifts from planning to execution. Although eye and arm movement temporally overlapped, phase clustering analyses enabled us to resolve differences in eye and arm information across brain regions. This analysis revealed that eye and arm information spatially overlapped in motor cortex, which we further confirmed by demonstrating that arm movement decoding performance from motor cortex activity was impacted by task-irrelevant eye movements. Phase clustering analyses also identified reward-related activity in the pre-frontal and premotor cortex. Our results demonstrate µECoG’s strengths for functional mapping and provide further detail on the spatial distribution of eye, arm, and reward information processing distributed across frontal cortices during reaching. These insights advance our understanding of the overlapping neural computations underlying coordinated movements and reveal opportunities to leverage these signals to enhance future brain-computer interfaces.

Significance statementPicking up your coffee mug requires coordinating movements of your eyes and hand and processing the outcomes of those movements. Mapping how neural activity relates to different functions helps us understand how the brain performs these computations. Many mapping techniques have limited spatial or temporal resolution, restricting our ability to dissect computations that overlap closely in space and time. We used micro-electrocorticography recordings to map neural activity across multiple cortical areas while monkeys made goal-directed reaches. These measurements revealed high spatial and temporal resolution maps of neural activity related to eye, arm, and reward information processing. These maps reveal overlapping neural computations underlying movement and open opportunities to use eye and reward information to improve therapies to restore motor function.
Two Cases of Pancreatobiliary Disease Complications Treated Using Over-the-Scope Clip
Authors: Kwan Byung Soo , Sung Bo Ram , Kim Kwang Min
Published: January 2025

The over-the-scope clip (OTSC) system is a powerful full-thickness suturing device used for closing refractory bleeding, perforations, and fistulas in gastrointestinal diseases, offering greater force than conventional clips. Here, we report two cases of pancreatobiliary disease treated using OTSC. The first case involved the successful OTSC ligation of a colonic fistula caused by necrotizing pancreatitis, and the second was a duodenal perforation due to stent migration, which was also successfully treated with OTSC. These cases indicate that OTSC can be beneficial for pancreatobiliary diseases, potentially eliminating the need for surgery when endoscopic treatment is successful.

Published: January 2025

Educational tourism or edutourism is a tourism activity that aims to provide learning experiences and skills development. Universitas Negeri Semarang (UNNES) has developed edutourism activities with various themes, but this edutourism is still less well-known to the public. Therefore, the environmentally friendly concept is applied as a characteristic of UNNES edutourism. This activity aimed to increase knowledge, understanding, and skills in developing environmentally friendly edutourism for students. This environmentally friendly edutourism service activity was carried out through three stages, 1) introducing environmentally friendly edutourism, 2) introducing environmentally friendly energy, and 3) activity evaluation. The series of edutourims activities carried out on Wednesday, June 19, 2024, involved elementary school students (SD) who particpated in various activities, including colouring gypsum animal characters to increase creativity and introducing environmeltal conservation, as well as a tour of the Innovation House to understand environmentally friendly energy products. In addition, participants also toured the campus using electric cars that introduced renewable energy applications. The activity results showed that all participants were enthusiastic, understood the environmentally friendly concept, and were interested in participating in similar activities in the future.
Levels of criminal law policy in the field of ensuring the protection of criminal justice bodies
Authors: Karabin Yevhenii
Published: January 2025

The article provides a comprehensive analysis of approaches to determining the levels of criminal law policy in the field of ensuring the protection of criminal justice bodies. The existing scientific concepts regarding the level differentiation of criminal law policy are examined, including doctrinal, programmatic, legislative, law enforcement, law execution, and scientific levels. An alternative approach that involves division into law-making, interpretative, and law enforcement criminal law policy is analyzed. Special attention is paid to the territorial criterion of criminal law policy distribution and the expediency of its application for research in the field of ensuring the protection of criminal justice bodies is substantiated. Based on the analysis of horizontal differentiation of criminal law policy into internal and external, a modified vertical-horizontal approach to distinguishing levels of criminal law policy in the studied field is proposed. According to this approach, a supranational (interstate) level corresponding to external policy and a state level covering internal policy and including national, regional, and local levels are identified. The specifics of the supranational level in the context of EU criminal law regulation and peculiarities of establishing international standards for ensuring the protection of criminal justice bodies are considered. Key international documents defining standards in the field of law enforcement and their influence on national legislation formation are analyzed. The necessity of a balanced approach to criminal law policy research is substantiated, which involves combining the study of institutional and functional aspects with the analysis of criminal law norms of a general-tendential nature
Editorial: el pensamiento histórico y el legado del Dr. Peter Seixas
Authors: Gibson Lindsay
Published: January 2025

Despite the huge gap between the practices of the historical discipline and what is possible in school history, Seixas was convinced that historical thinking can make an important contribution to the teaching of history by using and conceptualizing the tools, processes and ways of historical thinking that help students understand who they are, where they are and what they can do (as individuals, as members of multiple intersecting groups, and as citizens with roles or responsibilities in a complex, conflict-ridden and rapidly changing world). To meet these important challenges, new theoretical, empirical and practical advances are required.More theoretical work is needed to articulate the purposes of history teaching that can be applied in multiple contexts and accommodate diverse forms of historical consciousness.

Published: January 2025

This study examines reading behavior from five perspectives, including self-perception of reading, reading behavior, access to reading, reading interests, and context, among students at the University of El Salvador's Faculty of Sciences and Humanities. It was carried out using the quantitative method, where a questionnaire technique was applied (an adaptation of the one used by CEPLI at the University of Castilla La Mancha). The results reveal that the students have the skills needed for reading and provide a picture of habitual readers, but their reading habits don’t necessarily reflect a general interest in leisure reading.  Digital is typically used as a reading aid. Different gender traits are identified in relation to self-perception of reading, reading behavior, and reading interests.  However, there is a small proportion of students that read in a daily and academic environment that does not support reading.
Formación de ciudadanías críticas como herramienta contra la proliferación de discursos antidemocráticos: la importancia de transitar desde los conceptos a la experiencia en los sistemas educativos chileno y costarricense
Authors: Jara Pérez Katherine Pamela , Salazar Chavarría Kenett
Published: January 2025

We find ourselves in an international political scenario marked by tensions: new armed conflicts and others that seem to refuse to disappear, political discourses that relativize the most elementary principles of democracy and human rights. This is a situation from which Latin America has not been exempt, on the contrary; our time is witnessing the proliferation of populist and authoritarian movements. Faced with this panorama, the following essay vindicates critical pedagogy as a basis for the development of critical and disruptive citizenship in school environments in relation to the hegemonic project expressed in the official curricula. Thus, from the reflections generated by the teaching exercise in Chile and Costa Rica, the analysis of official documents and the theoretical baggage inherited from critical thinking, the need to position citizenship as a practical exercise is raised, which allows moving from conceptual approaches to other experiential ones; where the democratization of the word, deliberation, the defense of human rights and nature are tools that allow sketching truly equitable societies, respectful and capable of valuing the existing epistemic heritages in the different educational communities. All this in response to the increase of structural violence and proliferation-materialization of anti-democratic discourses that permeate the whole of Latin American societies.

Published: January 2025

La criptofauna está conformada por una gran diversidad de filos de Metazoa cuya composición y abundancia varía de acuerdo con distintos factores ambientales, por ello aportan información clave para monitorear ambientes coralinos. Los arrecifes artificiales han sido una herramienta que ha permitido recolectar fauna críptica y aportar información sobre la biodiversidad de los ecosistemas marinos. La criptofauna sésil y móvil, se evaluó en cuatro estructuras autónomas de monitoreo arrecifal ubicadas en noviembre de 2016 en un sector del Banco de las Ánimas a 14 m de profundidad y fueron retiradas a los seis, nueve, doce y 18 meses. Los organismos recolectados fueron identificados hasta el menor nivel taxonómico posible y se analizó su abundancia y variación temporal. La mayor abundancia fue de Arthropoda, Annelida y Mollusca y los filos menos conspicuos fueron los Nemertea y Cnidaria. Los moluscos Parvanachis obesa, Muricopsis cf. withrowi y Anomia ephippium, el anélido Poecilochaetus johnsoni, el artrópodo Balanus y las Ascideas fueron los más frecuentes. La composición del ensamblaje de organismos crípticos fue similar a lo largo del tiempo y fue claro que el asentamiento de larvas dependerá de la identidad de los colonizadores. Este estudio aporta al conocimiento de la diversidad marina del Caribe colombiano y se suma a los inventarios sobre la biodiversidad del Banco de las Ánimas; un corredor biológico entre el Parque Nacional Natural Tayrona y la ciénaga Grande de Santa Marta. Finalmente se recomienda, realizar estudios de larga duración para apreciar patrones de colonización y sucesión de las especies crípticas.
Multi-temporal analysis of land cover changes due to hurricanes Iota and Eta on the islands of San Andres, Providencia and Santa Catalina

Published: January 2025

This study analyzes the how the land cover on the islands of San Andres, Providencia and Santa Catalina, Colombia, was impacted by hurricanes Iota and Eta in 2020. A multitemporal analysis using Sentinel-2 satellite images of the years 2020 and 2021 was conducted to identify changes in land cover and the spectral responses of the NDVI, NDWI, BSI and NBR indices. The results indicate that on Providencia and Santa Catalina the most affected types of land cover were forests, mangroves, secondary vegetation and beaches, particularly in the north and northeast of Providencia and throughout the entire area of Santa Catalina. On San Andres, mangrove forests and grasslands on the eastern and southern coastal edge of the island were the most affected types of cover. This kind of analysis is important to decision makers in coastal land planning because it represents the behavior of land cover in coastal areas in response to disturbances induced by hurricanes, and thus helps us to understand how such extreme natural phenomena influence islands.

Authors: Orozco Miranda Royner , Brenes Castro Vincent , Cubillo Alvarado Valeria , López Morales Amanda , Vega Morales Keylin
Published: January 2025

La clasificación corresponde a un proceso de gestión de información que permite la asignación de clases o temáticas a un conjunto de documentos, con la finalidad de que sean accesibles de manera eficiente y eficaz en unidades de información como archivos, bibliotecas y centros de documentación. Al comparar algunas ciencias de la información como la archivística y la bibliotecología, es posible reconocer que la clasificación establece un conjunto de pautas que permiten una adecuada organización, almacenamiento y recuperación de la información. Desde un enfoque cualitativo, con una investigación descriptiva, se pretende detallar las principales características relacionadas con los tipos de clasificación de la archivística y la bibliotecología empleados en Costa Rica, las cuales han sido abordadas en la formación profesional para conocer el panorama teórico-práctico en torno a ambas ciencias en el contexto nacional. Los resultados finales de la investigación, detallan que si bien existe una consolidación de los sistemas de clasificación en bibliotecología, en la archivística predomina un proceso de evolución de este proceso acorde a las nuevas necesidades del mercado a nivel nacional. Una vez finalizado el análisis, se concluye que ambas ciencias tienen objetos de estudio diferentes, pero con el objetivo en común de brindar un tratamiento adecuado a la información según las necesidades de las partes interesadas.

Authors: Chen Jiahao , Chen Jiaxuan , Chen Liquan
Published: January 2025

Abstract: To reveal how sport ice and snow sculptures redefine natural beauty, in the context of modern art, and explore their implications for landscape architecture design, this article uses a combination of literature review and case analysis to explore the aesthetic value, artistic form, and philosophical foundation of sport ice and snow sculptures in gardens and analyzes specific cases of sport ice and snow sculpture art forms in landscape architecture. Research has shown that the understanding of natural beauty, by modern art philosophy, has gone beyond the scope of traditional aesthetics and is more concerned with the interaction between nature and humans. Sport ice and snow sculpture is a unique form of landscape architecture that not only embodies the aesthetic characteristics of natural materials, but also expresses profound reflections on the natural environment through technological innovation, artistic creation and other means. This article provides a new perspective on the creation of landscape architecture and further enriches the aesthetic connotation of modern gardens.

Abstract Stryphnodendron adstringens (Mart.) Coville, commonly known as “barbatimão,” is native to the Cerrado biome in Brazil and belongs to the botanical family Fabaceae. The objective of this study was to evaluate the biological activity of crude hydroethanolic extracts formulated from the bark, leaves, and stems of S. adstringens. Soluble solids were determined using the incubation drying methodology. Colorimetric methods of complexation with ferric chloride were employed as a qualitative assay to identify the presence of tannins, while phenolics and flavonoids were quantified by the Folin-Ciocalteu method and aluminum chloride complexation, respectively. Antioxidant activity was assessed by the capture of DPPH free radicals. Antibacterial and antifungal analyses in vitro were conducted using the disk diffusion method against Escherichia coli, Mycobacterium tuberculosis, Pseudomonas aeruginosa, Staphylococcus aureus, Candida albicans, and Cryptococcus neoformans var. grubii. The MTT assay was used to determine antiparasitic activity against Leishmania amazonensis and to assess cytotoxicity using differentiated THP-1 macrophages. The extracts demonstrated efficacy against yeasts, especially the stem extract against C. albicans (7.62 mm), and against bacteria, with emphasis on the stem and leaf extracts against M. tuberculosis (both 9 mm). All extracts exhibited high antioxidant capacity, particularly the leaf and stem extracts (both over 92%) and low cytotoxicity (Cytotoxic Concentration - CC50 > 300 µg/mL). No extract was effective against L. amazonensis (Inhibitory Concentration - IC50 > 100 µg/mL). In conclusion, S. adstringens is a potential source of compounds with antibacterial properties (particularly against Gram-positive bacteria) and antifungal activity, with low cytotoxicity and high antioxidant activity. This work emphasizes the use of this plant as a source of molecules for the development of drugs against bacterial and fungal infectious diseases, as well as for combating diseases, such as cancer and neurodegenerative disorders, that are linked to cellular and DNA damage due to oxidative stress.
Chayanov's peasant utopia and contemporary perspectives of a more just and ecological society
Authors: Moruzzi Marques Paulo Eduardo , Alves José Caio Quadrado
Published: January 2025

Abstract For the sociologist Norbert Elias, the emergence of the utopian literary genre, initiated by Thomas More in the 16th century, constitutes an important indication of the transformation of the modern world. Since then, utopian works have expressed a growing number of reflections on the role of the State. It involves conceiving a model of social organization based on moral principles accepted as legitimate. Alexander Chayanov's thought is representative of these reflections by idealizing a peasant utopia as a perspective of a just world, with precursor principles of ecological justice. This type of utopia currently inspires choices and actions like those of the Landless Rural Workers Movement (Movimento dos Trabalhadores Rurais Sem Terra, MST) with a view to democratizing access to land. The concept of the “Comuna da Terra” settlement, advocated by the MST in the state of São Paulo, shares many points of affinity with Chayanov's utopia. Case studies of this nature is promising for discussing the construction of transformative orientations in Brazil.

Abstract The inclusion of wastes of clay brick (WCB) as a supplementary cementitious material (SCM) demands a processing process guided by the reactivity of the material. In this sense, the present study evaluated the influence of particle size on the pozzolanic reactivity of WCB. WCB of five distinct particle size distributions was compared to metakaolin, natural clay, and waste of clay tile (WCT). The assessment of pozzolanicity was based on the R3 reactivity test, using isothermal calorimetry and quantification of bound water content, in addition to the compressive strength and analysis by XRD/Rietveld of composite cement pastes type CPII-Z and CPIV. Reducing the D90% diameter of the WCB from 33 to 11 µm promoted an increase of 50% in pozzolanic reactivity. However, for D90% diameters below 11 µm, the increase in reactivity (2%) may not justify the costs associated with prolonging the grinding process. The results highlighted the feasibility of using the R³ test and the importance of beneficiation guided by reactivity, aiming to optimize the recycling potential of new materials in the production of composite cements.

The sale of cattle presents a significant opportunity to improve livelihoods for smallholder farmers in eastern Indonesia. An opportunity was identified to grow herbaceous forage legumes either in rotation with, or sown within, staple grain crops (maize, rice) to use surplus soil moisture to produce a feed bank for (mostly penned) cattle and potentially increase nitrogen supply to the grain crops. A series of experiments was conducted on Vertisol, Alfisol and Inceptisol soils in lowland and upland districts of eastern Indonesia to identify legumes from 18 taxa suitable for integrated crop-forage systems. Clitoria ternatea and Centrosema pascuorum were found to have best potential for these systems as they established reliably using local methods, consistently ranked highly for herbage yields 2–4 months after sowing and were relatively easy to harvest. Yields were highest on the Vertisol (greatest number of sites) and Inceptisol soils. Lablab purpureus, Macroptilium bracteatum and Mucuna pruriens also ranked high for yield on Vertisol soils. Clitoria ternatea regrew consistently after cutting and forage removal providing potential for extended forage production as growing conditions allow.
