Проведен расчет исходного напряженного состояния слоистого массива горных пород, сформированного действием гравитационных сил и поля температур, линейно изменяющегося по глубине. Показано, что на характер распределения исходных напряжений определяющее влияние оказывает параметр δ, равный отношению произведений модулей объемных сжатий и коэффициентов линейного расширения слоев. В двухслойном массиве при значении δ больше единицы, вычисленному как отношение термомеханических характеристик пород верхнележащего слоя к нижележащему, температурное воздействие приводит к возникновению в нижележащем слое растягивающих вертикальных напряжений, меньше единицы - сжимающих вертикальных напряжений. В случае значительного отличия δот единицы в нижележащем слое происходит резкое увеличение исходных вертикальных и горизонтальных напряжений, причем характер распределения напряжений близок к гидростатическому. Выполнено математическое моделирование перераспределения полей температур напряжений по мере развития очистных и закладочных работ при применении слоевых систем с нисходящим порядком выемки запасов полезных ископаемых. Расчеты проведены с помощью программного комплекса, учитывающего последовательность ведения закладочных работ. Установлены особенности напряженного состояния вмещающего и закладочного массивов в ходе отработки.

The author calculates initial stress state generated under the action of gravity and temperature which changes linearly with depth in stratified rock mass. It is shown that the dominant influence is exerted on the initial stress distribution by the parameter δ which is a ratio of products of triaxial compression moduli and linear expansion factors of rock layers. In two-layer rock mass, when δ calculated as a ratio of thermomechanical characteristics of the upper and lower layers is higher than one, the temperature effect results that the tensile vertical stresses are induced in the lower layer; when suchwise calculated δ is lower than one, the compressive vertical stresses arise in the lower layer. In case of a great divergence of δ from one, in the lower layer, the initial vertical and horizontal stresses increase jump-wise, and the stress pattern resembles a hydrostatic stress distribution. The author performed mathematical modeling of thermal stress field redistribution during advancing undercut-and-fill operations. The software used in the calculations took into account the backfill sequence. The features of stresses in enclosing rock mass and in backfill were revealed.

Экспериментально измерено газовыделение при разрушении образца угля в мельнице. По методике ИГД им. А. А. Скочинского рассчитано количество газа, которое может выделиться из угля в зависимости от размера его частиц. Образцы отбирались с выбросоопасного угольного пласта. Установлено, что уменьшение размеров частиц угля до 0.1 мм повышает газовыделение в несколько раз. Разработана модель силового взаимодействия молекул метана в микропористой структуре с поверхностью макромолекулы угля и методика расчета газовыделения из угля в зависимости от степени его разрушения.

Gas emission during destruction of coal samples in a mill is measured experimentally. Using the Skochinsky Institute’s procedure, emmitable gas amount is calculated as function of coal particles. Coal samples for the tests were taken in an outburst-hazardous seam. It is found that the decrease in the size of coal particles to 0.1 mm increases gas emission by several times. The authors developed a model of force interaction between methane molecules in micro-porous coal structure and surface of coal macro-molecule, and a calculation procedure for gas emission in coal as function of its degree of breakdown.

Обобщены исследования по получению ванадия и показана перспективность применения флотационного извлечения. Обоснован прогнозный выбор фульвовой кислоты FulvAcв качестве реагента-собирателя, селективно действующего по отношению к ценному компоненту ванадию, который в кислых продуктивных растворах находится в виде ванадила VO2+ . На основе анализа параметров реакционной способности изучен механизм выделения и концентрирования ванадила с использованием хелатообразующего реагента FulvAc. Проведено компьютерное моделирование флотационной системы, представляющей собой малорастворимый металлокоплекс фульвата ванадила [VO2+ - FulvAc]n . Эффективность применения FulvAc подтверждена лабораторными флотационными тестированиями, при которых извлечение ванадила составило не менее 92 %. Получение оксисолей ванадия обусловлено потребностями в сырье различных отраслей, [VO2+ - FulvAc]n можно использовать в качестве комплексных минеральных добавок в удобрительные смеси для нужд городского озеленения.

The studies on vanadium production are generalized, and the promising nature of flotation is demonstrated in this regard. The prognostic selection of fulvic acid FulvAc as a selective collecting agent relative to vanadium occurred as vanadyl VO2+ in acidic pregnant solutions is justified. The analysis of chemical reactivity studied the mechanism of vanadyl extraction and concentration using chelating agent FulvAc. Computer modeling is performed for a flotation system representing a slightly soluble metal complex of vanadyl fulvat [VO2+ - FulvAc]n . Efficiency of FulvAc is proved by lab-scale flotation tests with recovery of vanadyl not less than 92%. Vanadium oxisols are demandable by different industries, and [VO2+ - FulvAc]n is usable as complex mineral supplements for fertilizing mixtures for urban greening.

Рассмотрены реагентные режимы обратной флотации нефелина из хвостов обогащения лопаритовых руд: смесь талловых масел, гидроксамовые кислоты в сочетании с дистиллированным талловым маслом; смесь талловых масел с добавкой полиалкилбензолсульфокислоты или аминосодержащих собирателей. При использовании оптимальных реагентных режимов получен нефелиновый концентрат с содержанием Al2O3 27.18 - 27.57 %. При добавке к талловым маслам полиалкилбензосульфокислоты активность собирательной смеси уменьшилась, приведя к снижению качества получаемого концентрата до 26.33 % Al2O3. Рассмотрено два способа доводки флотационных концентратов до кондиционного качества. Использование магнитной сепарации позволило получить нефелиновый концентрат с Al2O3 28.0 - 28.3 % при извлечении 72 - 76 % от исходного продукта. Методом прямой катионной флотации с применением реагента Flotigam-2835 в кислой среде с рН 4.5, создаваемой кремнефтористым натрием, получен нефелиновый концентрат с 29.63 % Al2O3 при извлечении 65.9 % от исходного продукта.

The authors analyzed some reagent regimes in flotation of nepheline from loparite ore tailings: mixture of tall oils, hydroxamic acids in combination with distilled tall oil; mix of tall oils with addition of polyalkyl benzene sulfonic acids or amine-containing collectors. The nepheline concentrate produced in the optimized reagent regime contained Al2O3 27.18-27.57%. With addition of tall oil polyalkyl benzene sulfonic acid, activity of the collecting mixture reduced, and the produced concentrate quality lowered to Al2O3 26.33%. Two methods to bring flotation concentrates to a standard quality are discussed. The use of magnetic separation allowed production of nepheline concentrate with Al2O3 28.0-28.3% at the recovery of 72-76% compared to the initial product. Direct cationic flotation with agent Flotigam-2835 in an acidic medium with рН 4.5, created by sodium silicofluoride, produced nepheline concentrate with Al2O3 29.63% at the recovery of 65.9% compared to the initial product.

It Takes a Group to Design but a Larger Community to Implement: Social Justice Language Education-Oriented Framework in Costa Rica
Authors: Rojas-Alfaro Roberto , Ramirez-Casalvolone Natalia
Published: January 2025

While social justice education (SJE) is increasingly recognized as educationally essential for students’ academic and personal success, its full integration into K-12 education continues to face barriers, including resistance to discussing certain SJE topics. Using group interviews with five regional- and two national-level English-as-a-foreign-language (EFL) advisers tasked with leadership and curriculum advocacy in Costa Rica, this study explored their responses to proposed SJE-themed curriculum materials for online and offline education. Findings include concerns around the practical challenges of adding tasks to already-overburdened teachers’ workloads, aligning curricula with mandated educational benchmarks, and apprehension about introducing certain SJE topics, especially around sexuality and socioeconomic status. Recommendations include leadership support for focused SJE implementation and increased stakeholder input around developing and navigating real or anticipated SJE resistance in certain social sectors and refining proposed SJE materials to meet educational mandates without adding to teacher workloads.

Análisis de administración del tiempo en ingeniería como estrategia de mejora de rendimiento y reduccion de estrés laboral
Authors: Rodríguez Rojas Einer
Published: January 2025

El estrés laboral se ha convertido en uno de los principales trastornos de salud a nivel mundial. Las ocupaciones diarias terminan condicionando a las personas que para cumplir con sus obligaciones extienden sus jornadas laborales. Actividades importantes como compartir con los seres queridos queda rezagada a un segundo plano. Problemas físicos, problemas mentales y problemas de relaciones humanas son solo algunas de las consecuencias de estar atrapado en un círculo de influencia manejado por el estrés. Una alternativa para disminuir el estrés corresponde a tener una mayor disponibilidad de tiempo, recurso valioso e irrepetible que es posible administrar. La presente investigación tiene como objetivo brindar opciones para administrar de una mejor manera el tiempo para que finalmente se traduzca en una disminución del estrés. Para cumplir con el estudio se utiliza una muestra no probabilística por conveniencia. La recolección de datos se lleva a cabo mediante una plantilla predefinida. Se generaron una cantidad superior a 1300 datos que se procesan mediante estadística descriptiva para hallar posibles patrones de administración del tiempo. Al procesar los datos, se identifica una limitación al estudio que obliga a ajustar el modelo, la información puede ser objeto de subjetividad, pues la actividad que para uno de los individuos puede estar contenida en una clasificación, para otro, la interpretación podría ser diferente. Las conclusiones sugieren que los sujetos de estudio clasifican en mayor medida sus actividades como productivas, sin embargo, no en todos los casos se podría calificar como actividades asociadas a objetivos a mediano plazo, muchas de ellas se rigen por la urgencia y corresponden con la rutina.  La creación de hábitos y herramientas como la capacidad de delegar son esenciales para cumplir con las tareas.

RESUMO O objetivo deste artigo é apresentar uma análise da atuação da Federação dos Trabalhadores na Agricultura do Estado de Minas Gerais (Fetaemg) em seus primeiros anos de existência (1968-1974), período também marcado pela maior repressão da ditadura militar no Brasil. O trabalho está centrado nas relações entre os diferentes atores (trabalhadores(as), latifundiários(as), sindicalistas, governo, etc.) no contexto ditatorial. A pesquisa foi realizada com base em diversas fontes, disponíveis no Arquivo Nacional, na Hemeroteca Digital Brasileira, no Arquivo Público Mineiro (APM), na Comissão Pastoral da Terra (CPT) e no Centro de Documentação Eloy Ferreira da Silva (CEDEFES), assim como em entrevistas que realizamos com sindicalistas ligados à Federação. Dessa forma, buscamos conhecer as circunstâncias concretas em que se deram as estratégias desses atores, suas aspirações, as tensões, as limitações impostas e as conquistas, naquele contexto. Pelo que pudemos perceber, o perfil inicial de atuação da Fetaemg foi constituído, em parte, pela origem de seus dirigentes em setores conservadores da Igreja Católica, assim como pelas tensões, vigilância e repressão que sofreram, levando-os à definição da prudência como parâmetro vital para continuidade de suas ações em prol das(os) trabalhadoras(res) rurais.

Published: January 2025

ABSTRACT The biochemical profile and milk fats/proteins in Saanen and Nubian goats from Los Asmoles, Colima was carried out. Milk fat, milk protein, fat/protein ratio, glucose (GLU), cholesterol (COL), non-esterified fatty acids (NEFA), triacylglycerol (TAG), β-hydroxybutyrate (β-HBA), blood urea nitrogen (BUN), albumin (ALB), globulin (GLOB), total protein (PROT-T), calcium ion (Ca2+), inorganic phosphate (Pi), sodium ion (Na+), potassium ion (K+), magnesium ion (Mg2+), and chloride ion (Cl-) was calculated. The biochemical profile results were consistent with the international literature for goats. All analytes except ALB and β-HBA showed racial differences. The three milk variables registered a higher concentration in Nubian. The comparison between groups (high-yield vs. low-yield vs. dry period) showed differences in COL and β-HBA in both breeds. A negative correlation between GLU and NEFA was quantified. Positive correlations between NEFA with COL, TAG and β-HBA, between Ca2+ with Na+ and between K+ with Na+ and Mg2+ were quantified. Milk fat was correlated with COL, NEFA and β-HBA. Milk protein was correlated with BUN. The fat/protein ratio was correlated with COL and β-HBA. Results provide insight into metabolic adaptations in lactation and identify links between key analytes and milk fat/protein in goats.
A dialética da “ninguendade” e o desprendimento: a decolonialidade em Darcy Ribeiro e sua contribuição para os estudos organizacionais
Authors: LOUREDO FÁBIO MOITA , WANDERLEY SERGIO
Published: January 2025

Resumo O movimento de globalização evidenciou a hegemonia dos países centrais na produção e na disseminação do conhecimento em gestão e organizações. O saber produzido nessa configuração geopolítica parte de um lócus de enunciação que tem um caráter universalizante e ignora as idiossincrasias da sociedade e da cultura brasileiras, revelando incongruências ao analisar nossas práticas e organizações, desprezando o pensamento de intelectuais e acadêmicos brasileiros. Neste ensaio teórico, defendemos que Darcy Ribeiro contribui para a reflexão sobre a questão identitária das teorias reproduzidas em estudos organizacionais no Brasil. Para isso, propomos a articulação entre o conceito de “ninguendade”, de Darcy Ribeiro, e a abordagem teórica do desprendimento, desenvolvida por Walter Mignolo, como expressão de reexistência e resposta ao imperativo de localizar historicamente o espaço e a dinâmica do estudo do campo organizacional. Como contribuição teórica, apontamos que a opção decolonial e o pensamento social brasileiro podem subsidiar um novo olhar à realidade organizacional e acadêmica no campo dos estudos organizacionais.

Published: January 2025

In this investigation, Zinc Sulfide (ZnS) nanoparticles and nanocomposite powders such as Zinc- Aluminium (ZnS-Al), Zinc- Platinum (ZnS-Pt), and Zinc- Aluminium-Platinum (ZnS-Al-Pt) were fabricated using the co-precipitation method, employing zinc acetate and sodium sulfide as primary materials. The proposed composite powders were thoroughly characterized using techniques like Energy-dispersive X-ray Spectroscopy, X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Ultraviolet-Visible (UV-Vis) absorption spectroscopy, and photoluminescence analysis. To investigate the structural characteristics of the nanocomposites XRD was employed, and the Debye-Scherrer equation was applied to calculate their crystallite sizes. SEM examinations provided detailed insights into the morphology of the nanocomposites. The optical properties were assessed through UV spectroscopy, which showed that the ZnS nanocomposites displayed a prominent absorption peak in the 295-300 nm range, with the highest absorption at 299 nm, and a bandgap energy of 3.75 eV. This indicates a notable blue shift compared to the spectrum of bulk ZnS. Furthermore, the photoluminescence analysis indicated that the ZnS nanocomposites are capable of emitting light at a wavelength of 400 nm. These findings underscore the significant promise of ZnS nanocomposites and their possible use in supercapacitors as sophisticated electrode materials.

Authors: Coelho Maíra , Zonta Marise Bueno , Raskin Salmo , Valderramas Silvia
Published: January 2025

ABSTRACT Objectives: The aim of this study was to assess the perception of quality of life of patients with spinal muscular atrophy (SMA) and investigate whether there is a correlation between patients’ perception and that of their carers. Methods: Cross-sectional analytical observational study. In the first part, socioeconomic, demographic, clinical, and treatment information were collected from patients diagnosed with SMA, regardless of type, sex, or age. SMA type 1 does not sit; SMA type 2 sits; SMA type 3 walks; and SMA type 4 begins in adulthood. In the second part of the study, patients aged between 2 and 25 years and their caregivers responded to the Pediatric Quality of Life Inventory 4.0 questionnaire. Results: Of the 235 families recruited, 167 were eligible to respond to the questionnaire, 115 caregivers and 49 patients were included. The results point to a different perception of quality of life between patients and caregivers. Patients with SMA type 2 perceive more impaired physical and emotional capacity compared to SMA type 3 and 1, respectively. As for caregivers, the perception of quality of life in relation to physical and social capacity and the total score are worse for patients with SMA type 1 compared to other types. Perceptions correlate with emotional capacity in SMA type 2 and the total aspect in SMA type 3. Conclusions: Patients with SMA type 2 had a worse perception of their quality of life than other patients. Perception differed between patients and their caregivers, with the former having a better perception than the latter.

ABSTRACT Objective: To investigate the presence of metabolic dysfunction-associated fatty liver disease (MAFLD) and gallbladder abnormalities in a sample of people with Down syndrome in Brazil. Methods: This is a retrospective study using medical charts involving Down syndrome patients, diagnosed by karyotype, aged over 5 years, who underwent abdominal ultrasound and were monitored by the same professional in a clinic in Curitiba, Brazil. Data spanned January 1995 to September 2023; all cases with no use of alcohol or hepatotoxic medications. Results: A total of 124 patients were evaluated, 64 (51.6%) being females. Ages varied between 5 and 30 years (average of 13.2±5.7 years). Body mass index ranged from 14.08 to 44.98 kg/m2, with 27 (21.7%) patients being overweight and 42 (33.8%) obese. The frequency of increased total cholesterol and triglyceride concentrations was significantly higher in children. No age or sex differences were seen in low- and high-density lipoprotein cholesterol. Alanine transferase (ALT) and aspartate transferase (AST) levels were within normal ranges and showed no differences concerning sex or age. Four patients (3.2%) had diagnosis of MAFLD. The prevalence of gallstone varied widely in terms of the number and size of stones among patients, affecting 11 (8.9%) of them, with no significant difference in age or sex. Conclusions: MAFLD was found in 3.2% of the individuals, while gallstone disease was identified in 8.9% of the cases studied. Moreover, we noted a significant presence of risk factors associated with MAFLD, with dyslipidemia being the predominant factor.

O esquecimento triunfal e derrotado: Álvaro de Campos e a filosofia nietzschiana do esquecimento
Authors: Hongze Song
Published: January 2025

Resumo Este trabalho analisa a relação entre Nietzsche e Álvaro de Campos, um dos heterónimos mais representativos de Fernando Pessoa, a partir da representação do esquecimento nos seus poemas. Em primeiro lugar, encontramos uma evolução do olvido de Campos do esquecimento do ópio, ao esquecimento futurista positivo, e, por fim, a um auto-esquecimento. Neste processo, o objeto do seu esquecimento desloca-se dos valores cristãos e racionais para o Si-mesmo do sujeito. Ao mesmo tempo, o esquecimento degenera também de uma resistência às doenças decadentes para uma fonte dos sintomas niilistas. Neste sentido, concluímos que a poética de Campos tenta alcançar o esquecimento nietzschiano, mas acaba por não o conseguir realizar.

Abstract- Initial findings indicate that while offline internships offer more opportunities for hands-on experience and direct mentorship, online internships provide greater flexibility and accessibility, allowing students to balance academic and professional commitments more effectively. Quantitative analysis reveals no significant difference in overall task completion rates between the two groups. However, qualitative feedback suggests variations in skill acqui- sition and professional networking opportunities, with offline interns reporting higher satisfaction in these areas. This research investigates the comparative impact of offline and online internships on student perfor- mance, with a focus on skill development, profes- sional growth, and academic outcomes. The study employs a mixedmethods approach, combining quantitative data from student performance metrics and qualitative insights from surveys and interviews. A cohort of 600 postgraduate students, from two batches of a postgraduate professional program, who participated in offline and online internships, was analysed over a period of six months. Key performance indicators, including task completion rates, supervisor evaluations, and selfreported skill acquisition, were assessed. The study concludes that both offline and online internships have unique advantages and limitations. Offline internships tend to foster practical skills and direct professional relationships, while online internships excel in providing accessibility and flexibility. Recommendations are provided for educational institutions and employers to enhance the structure and support of both internship modalitiesto maximize student outcomes. Future research should explore long-term career impacts and sectorspecific performance differences to further elucidate the efficacy of each internship format.

Abstract— In this study, the traditional educational system of India has been contrasted with the contemporary educational systems throughout the world using digital manufacturing technologies like 3D printing and computer numerical control (CNC). Aspects of the future of education will be revolutionized by this technology, as well. In order to explore the students’ perspectives on the integration of this prototype technology into India's educational system, the study used semistructured interviews. The data were analyzed using a content analysis approach, and the emerging themes were explored using verbatim texts. The results show that educators and students are really engaged and persuaded that, like computers design software, prototype technology would soon bring about another revolution in India's educational system. They depend heavily on contemporary teaching methods to convey novel concepts in concrete ways. They emphasized how this technology had affected their present methods and how elementary and basic education could use it to foster greater comprehension in creative minds.

Introduction: University studies often reduce physical activity (PA), which can harm students’ fitness and cardiovascular health, a trend worsened by the COVID-19 pandemic. Materials and Methods: We examined resting heart rate (RHR), aerobic capacity, and VO₂ max in students from two universities in Košice, Slovakia. The study included 586 students (227 males, 359 females; mean age = 19.75 ± 1.55 years) from UPJŠ and TUKE, selected during physical education classes in 2021/2022 and 2022/2023. We recorded the total number of shuttles and aerobic and anaerobic threshold times in a 20-m shuttle run test (SRT). Results: Male students at TUKE showed superior aerobic performance and fitness compared to their counterparts at UPJŠ, with lower RHR (MED = 60.0 bpm vs. 65.0 bpm), superior aerobic capacity (MED = 152.0 sec. vs. 110.0 sec.), and increased VO₂ max (MED = 46.4 vs. 43.1 ml/kg/min). UPJŠ female students outperformed TUKE females in VO₂ max (MED = 33.2 vs. 29.9 ml/kg/min), despite their superior aerobic capacity. There were significant correlations between RHR, aerobic capacity, and VO2 max, particularly in TUKE females (rs = -0.4359, p < 0.05), indicating gender and university-specific patterns. Results show significant cardiovascular fitness differences between universities. Conclusion: TUKE male students had higher VO₂ max, aerobic capacity, and lower RHR compared to UPJŠ peers, while UPJŠ female students had slightly higher aerobic capacity Female groups showed less differences, which may be related to their motivation and effort. Future research should use controlled RHR measurements and systematic tracking to understand how diet, sleep, and stress affect students' fitness.

The present study identifies the most critical practical challenges related to gender issues that elite female athletes and their coaches face when utilizing classical methods to monitor and assess general physical preparedness. Material and methods. An innovative approach was taken by conducting experimental studies to assess the practical effectiveness of applying classical scientific methods to gender differences in the overall physical fitness of elite female athletes. This approach, particularly in strength exercises such as the barbell squat, facilitated a multidimensional understanding of the profiles of 41 elite male and female athletes in team sports, including method of expert evaluation, psychophysiological, anthropometric, and biomechanical analyses. Considering the hormonal fluctuations inherent to the female body, we analyzed the results of a specialized Romberg test recorded exclusively during and designed for use with the optimal phases of the menstrual cycle they were subjected to analysis. The results demonstrated that female athletes exhibited an even higher quality of balance function during barbell squats (216 ± 2%) compared to their male counterparts (173 ± 3%). Our research experiment demonstrated that female athletes and their coaches encounter several practical challenges. Most monitoring methods necessitate the use of laboratory equipment, significantly entail considerable financial and time temporal costs, and are challenging to implement. Conclusions. In the context of new evolving technologies, the logistical challenge of developing reliable methodologies to monitor and suport women's health in the context of fitness and sport is evident, as optimizing performance and ensuring long-term well-being is of crucial paramount importance.

The objective of this study is to present the sports discipline of football in a multiethnic society within Ternopil Province during the years 1920-1939.The area of Ternopil Province was located in the south-eastern part of the Second Polish Republic, and sports clubs and associations within the province that ran football sections were affiliated with the Lviv Regional Football Association (Lviv OZPN). The establishment of the aforementioned sub-region had a positive impact on the development of football in the area discussed, with the number of clubs and associations running football sections increasing in the 1920s and 1930s. Football was played by Polish, Ukrainian and Jewish citizens inhabiting Ternopil Province. This proliferation of clubs contributed to an enhancement in the calibre of football in Ternopil province. The following football teams were the most prominent in Ternopil province: the Military-Civilian Sports Club (Wojskowo-Cywilny Klub Sportowy –WCKS) Kresy Tarnopol, WCKS Janina Złoczów – uniting Polish citizens; the Jewish Sports Club (Żydowski Klub Sportowy (ŻKS) Jehuda Tarnopol, ŻKS Złoczów – uniting Jewish citizens, and the Ukrainian Sports Association (Ukraińskie Sportowe Towarzystwo) Podilla Tarnopol – uniting Ukrainian citizens. In the years 1927-1930, the footballers of Janina Złoczów played in class A (the highest class) matches of the Lviv OZPN.

Karate training involves extensive practice without physical targets. While target kinematic effect has been identified in taekwon-do, this phenomenon remains unexplored in Kyokushin karate. This study aimed to verify the extent of target kinematic effects in Kyokushin practitioners' front kicks through examination of acceleration, angular, and electromyographical data. Material and Methods: Nineteen male Kyokushin practitioners (mean age 27.05 years) participated. Movement data was collected using wireless sEMG system (3000 Hz) and MyoMotion inertial sensors IMU (ang. inertial measurement unit) (200 Hz). Participants performed front kicks under six conditions: before warm-up, after warm-up, and after shadow sparring, each with and without a target shield. Seven muscles were monitored via sEMG, while four inertial sensors tracked movement of the pelvis, thigh, shank, and foot. Results: Significant velocity differences emerged after shadow sparring (16.91 m/s target vs. 14.39 m/s non-target, p = 0.045). Foot segment acceleration nearly doubled with target presence (57.83 m/s² to 99.27 m/s²). Angular measurements showed consistent adaptations across body segments when striking the target. EMG analysis revealed limited differences, with only the rectus femoris showing significant changes in the initial phase. Conclusion: The study confirmed target kinematic effect in Kyokushin practitioners, manifesting through substantial changes in acceleration and joint angles, particularly in distal segments. Limited EMG differences suggest consistent muscle activation patterns despite technique modifications. These findings indicate air-striking practice may not fully replicate the biomechanical demands of striking physical targets.

El cambio climático es un problema global y heterogéneo que produce condiciones asimétricas y desiguales, cuyos efectos se diferencian a nivel local (Bárcen, et al., 2018). El aumento del nivel del mar, los cambios en los patrones climáticos y los eventos extremos más frecuentes, la pérdida de especies y ecosistemas, y otros cambios relacionados con el clima tienen un impacto diferencial como resultado de varios factores como la geografía y los ingresos, y son también configurados por roles, responsabilidades y derechos asociados con determinantes de estatus social y expectativas, incluyendo sexo, clase y casta (Thomas et al., 2019; Agostino y Lizarde, 2012; Carr y Thompson, 2014).

O artigo tem por finalidade enaltecer a cultura de comunidades tradicionais na Amazônia, a comunidade ribeirinha “Nossa senhora dos Navegantes” que existe a mais de trinta anos e o território “Quilombola do Abacatal” com trezentos anos (re)existência, ambas as comunidades possuem suas tecnologias sociais e lutam para sobreviver, já que ambas as estão localizadas na Região Metropolitana de Belém (RMB). Através da pesquisa-ação, foram realizadas visitas técnicas, rodas conversas com os moradores das comunidades e com líderes responsáveis e pelas pessoas que residem na região. Por serem comunidades que estão próximos aos núcleos urbanos, os problemas enfrentados por essas comunidades é justamente um progresso que não traz benefícios e o progresso pode fazer com que essas comunidades desapareçam ao longo dos anos. Através das técnicas em geoprocessamento, sensoriamento remoto e banco de dados, podemos identificar os problemas relacionado ao pseudoprogresso. Os resultados apontam que o pseudoprogresso relacionado com a sua geolocalização,  progresso e tradição, bem como o pseudodesenvolvimento com sua implicação e resistência geoespacial provocam mudanças por vários fatores, dentre estes, a falta de demarcação/titulação e monitoramento  o que dá margem à invasão de suas terras, por grandes projetos de “desenvolvimento” inescrupuloso, com o objetivo de desenvolver  a região de caráter incompatíveis com uso da terra e do manejo dos recursos naturais, provocando diminuição na área do território herdado de seus antepassados. Conclui-se que essa situação afeta os costumes e tradições pelo “progresso” que modifica hábitos ancestrais e religiosos nas comunidades “Nossa senhora dos Navegantes” e “Quilombola do Abacatal” culminando com a poluição, desmatamento, crescimento desenfreado de cidades o que vem a propiciar uma pseudo-evolução social e preservação da biodiversidade.

Este estudo analisa como o espaço e a memória são representados na cidade de São Luís (Maranhão) por meio da canção “Sobrados” de Papete. A pesquisa enfatiza a cidade como um local de recordação e identidade, em que a paisagem urbana resgata a memória coletiva do povo maranhense. Os versos de Papete revelam uma poesia repleta de lugares-comuns que traduzem o conceito de topofilia, definido por Yi-Fu Tuan como o vínculo emocional com o espaço. Além disso, com base nos teóricos Bachelard, Halbwachs, Pollak e Tuan, o estudo investiga como esses lugares de memória são evocados, muitas vezes desconectados do tempo cronológico, mas fortemente ligados às experiências coletivas e individuais. A cidade de São Luís é apresentada como uma paisagem nostálgica e sentimental, refletindo o apego às memórias culturais e históricas que moldam a identidade local. O trabalho evidencia a relevância da canção como meio de preservar e narrar as memórias do Maranhão.

CYToF has significantly advanced immunophenotyping, especially in exploratory settings where comprehensive characterization of immune populations is necessary but sample sizes are limited. It is a powerful tool for single-cell immunological assays, particularly for the detailed and simultaneous analysis of diverse immune cell populations. By using metal isotopes instead of fluorescent labels, mass cytometry eliminates the spectral overlap issues seen in optical flow cytometry, allowing robust analysis of around 60 individual parameters simultaneously. The technique involves increased complexity in the design, execution, and interpretation of experiments.
