The paper considered the architectural and circuitry model of a navigation device for an ultra-lightweight launch vehicle designed to improve the accuracy and reliability of positioning and orientation in flight conditions. The study utilized modern approaches to the integration of global navigation satellite system (GNSS) and inertial navigation system (INS) to achieve high accuracy and stability of the system. The key components of the device including UM980 module, LSM6DSV32X inertial measurement module, STM32 F7 series microcontroller, E220-400T30S radio module, LMR50410XDBVR converter based power supply and RS422 interface were described in detail. The UM980 module, including SAW and LNA filter blocks, demonstrated the ability to efficiently process incoming RF signals. The NebulasIV main function block combined GNSS BB, GNSS RF, interfaces and power management unit (PMU) modules, supporting multiple communication interfaces such as UART, SPI and I²C, as well as RTK and PPS signals. The study analyzed the integration and accuracy aspects of the module in navigation systems. The signal processing scheme of the inertial navigation system module was also presented, including digital filters, free-fall and activity/inactivity detection functions, and interfaces for data communication. User bias functions and filter modes are considered to ensure the accuracy and stability of the navigation device. The work lays the groundwork for further improvements in navigation technology, especially in the context of increasing availability and accuracy for small scale space launches.

Introdução: o suicídio pode ser entendido como um ato intencional de causar a própria morte, vindo acompanhado das ideações suicidas que é um pensamento que se refere a autoeliminação, sendo visto na maioria das vezes como a “única saída”. Percebe-se que os jovens, em sua maioria, dão sinais de desistência da vida e pedidos de socorro, frases constantes que remetem a autoexclusão que podem por vezes passar despercebidos. Atualmente o suicídio é uma das principais causas de mortes, com altos índices em todo o mundo. Frente a esses casos de suicídio estar os profissionais de enfermagem nas portas de entradas hospitalares. Objetivo: conhecer as estratégias da equipe de enfermagem frente aos adolescentes com ideações suicidas. Metodologia: Tratou-se de uma revisão integrativa da literatura, que foi norteada pela pergunta: "Quais foram as estratégias de acolhimento da equipe de enfermagem frente aos adolescentes com ideações suicidas?". A busca foi realizada nos meses de julho e agosto, utilizando a Biblioteca Virtual em Saúde (BVS) por meio das bases de dados online: LILACS, MEDLINE e BDENF. Para a seleção dos artigos, foram utilizados o operador booleano "AND" e descritores cadastrados no DeCS: Adolescência, Assistência de Enfermagem e Suicídio. Os critérios de inclusão adotados foram: artigos em português, inglês e espanhol, em texto completo, publicados nos últimos cinco anos. Foram excluídas teses, monografias e trabalhos que não atendiam ao objetivo proposto pelo estudo. Após a identificação dos artigos relevantes, realizou-se a leitura dos resumos e os artigos selecionados foram lidos na íntegra. Posteriormente, os resultados foram organizados em quadros e confrontados com a literatura pertinente. Resultados e Discussões: O adolescente com comportamento suicida precisa estabelecer vínculos com alguém que o compreenda e escute. A enfermagem desempenha um papel crucial na prevenção e no suporte às famílias, mas reconhece que as atividades preventivas ainda são limitadas na atenção primária. Por meio de escuta ativa e acolhimento, os enfermeiros podem identificar riscos e implementar ações para melhorar a qualidade de vida dos pacientes. No entanto, a falta de treinamento especializado é um desafio. Profissionais de saúde precisam de mais capacitação, especialmente para lidar com adolescentes em risco, criando espaços de escuta e apoio adequados. Conclusão: A enfermagem tem papel fundamental frente ao suicídio, oferecendo acolhimento, escuta ativa e suporte tanto ao paciente quanto à família. No entanto, há necessidade de maior capacitação profissional, especialmente no atendimento a adolescentes. A atenção primária é essencial para identificar e intervir nos fatores de risco de forma eficaz.

A reabilitação oral por intermédio da implantodontia é uma alternativa utilizada na perda dentária, entretanto, para que este tratamento seja possível, fatores como influências de doenças sistêmicas e medicamentos utilizados pelo paciente precisam ser verificados com atenção. Nesse contexto, um grupo de fármacos bastante utilizado são os bifosfonatos (BFs), amplamente utilizados para inibição da reabsorção óssea e tratamento de neoplasias malignas que influenciam diretamente no processo de formação óssea. O objetivo do presente estudo foi analisar por meio de uma revisão integrativa de literatura as consequências do uso dos bisfosfonatos na osseointegração de implantes dentários, com os seguintes objetivos específicos apresentar a fisiologia do reparo ósseo no processo de osseointegração de implantes,  explicar como se dá a interferência dos bisfosfonatos no processo de reparo ósseo pós cirurgia e se existe esta relação e citar os riscos da instalação de implantes em pacientes que fazem uso de bisfosfonatos.  Foi realizada uma revisão integrativa de literatura tomando como base artigos encontrados nas plataformas: Pubmed/Medline, Lilacs, quais foram selecionados 10 artigos devido sua relevância ao tema. A literatura atual mostrou um índice de sucesso considerável dentre os pacientes usuários de bisfosfonatos e que receberam implantes dentários, entretanto é importante que o cirurgião dentista tome algumas precauções e alerte o paciente sobre os riscos da perda do implante e da necrose dos maxilares em função do procedimento executado. Os bifosfonatos podem atuar como coadjuvante no tratamento de pacientes submetidos a procedimentos cirúrgicos bucais na implantodontia.

Authors: Freitas Pedro Lucas Figueira , Lopes José Augusto Bezerra
Published: October 2024

O encarceramento de indígenas, embora relativamente menor em números absolutos em relação a outros grupos, revela um contexto de marginalização e desrespeito aos seus direitos específicos. Muitos indígenas estão presos sem o respeito às suas culturas, línguas e tradições, enfrentando dificuldades no acesso aos intérpretes e uma proteção adequada, o que agrava sua vulnerabilidade no sistema judicial, onde frequentemente sofrem com a falta de reconhecimento de suas especificidades culturais e espirituais dentro das prisões, onde são submetidos às mesmas condições degradantes enfrentadas por outros detentos, já que sistema carcerário brasileiro, de maneira geral, não possui políticas adequadas para lidar com a diversidade étnica dos presos indígenas, agravando a exclusão e a invisibilidade dessas pessoas no contexto prisional. No decorrer do presente estudo, que trata-se de uma revisão bibliográfica de cunho qualitativo de impacto social, serão demonstradas a caracterização dessa violência no âmbito do respeito ao direito de expressão cultural dos povos indígenas, fazendo para tanto, um apanhado histórico sobre a violência e opressão vivenciada por estes povos no Brasil, bem como apresentar aspectos da legislação que versa sobre a proteção dos direitos étnicos dos indígenas sem deixar de analisar a utilização da aplicação do sistema jurídico-penal. Para isto, a pesquisa se fez baseada em extensa revisão bibliográfica que incluiu importantes artigos científicos, relatórios governamentais, livros e documentos acadêmicos que datam desde 1990 a 2024, onde busca apontar o enfrentamento dos povos indígenas no sistema carcerário brasileiro no que tange a violência étnica por estes sofrida.

Published: October 2024

Introdução: O linfedema é uma condição que afeta a drenagem linfática, levando ao acúmulo de líquido e ao inchaço, frequentemente observado em pacientes com artrite reumatoide (AR). A interação entre AR e linfedema complica o manejo clínico, uma vez que a inflamação crônica da artrite pode agravar os sintomas do linfedema. O tratamento cirúrgico, que inclui abordagens como a lipossucção e a cirurgia de bypass linfático, tem ganhado destaque nas últimas décadas, apresentando-se como uma opção promissora para pacientes que não respondem adequadamente a terapias conservadoras. A colaboração entre especialistas em cirurgia vascular e reumatologia é essencial para otimizar os resultados clínicos e a qualidade de vida dos pacientes afetados. Objetivo: Explorar as perspectivas do tratamento cirúrgico do linfedema em pacientes com artrite reumatoide, analisando a eficácia e segurança das intervenções cirúrgicas disponíveis. Metodologia: Para a realização da revisão, foram seguidos os critérios do checklist PRISMA, utilizando as bases de dados PubMed, Scielo e Web of Science. Os descritores empregados incluíram "linfedema", "artrite reumatoide", "cirurgia", "tratamento", e "cirurgia vascular". Os critérios de inclusão consistiram em: estudos publicados nos últimos dez anos, focados em intervenções cirúrgicas para linfedema em pacientes com AR, e que apresentassem dados clínicos relevantes. Os critérios de exclusão abrangeram artigos que não discutiam diretamente a cirurgia, aqueles com amostras de pacientes sem AR, e revisões ou opiniões que não continham dados originais. Resultados: Os resultados indicaram que as intervenções cirúrgicas proporcionaram melhorias significativas na qualidade de vida e na redução dos sintomas de linfedema. A lipossucção, em particular, destacou-se como uma técnica eficaz para o manejo do linfedema, mostrando redução do volume do membro afetado e melhora na função. A integração de equipes multidisciplinares foi considerada fundamental para o sucesso dos tratamentos. Conclusão: O tratamento cirúrgico do linfedema em pacientes com artrite reumatoide mostrou-se promissor, evidenciando benefícios significativos. A combinação de técnicas cirúrgicas apropriadas e a colaboração entre especialistas em cirurgia vascular e reumatologia foram cruciais para a otimização dos resultados clínicos. Estudos futuros são necessários para estabelecer protocolos padronizados e avaliar a durabilidade dos resultados a longo prazo.

Published: October 2024

Abstract. Particle light absorption enhancement, also known as the lensing effect, is a complex phenomenon where particles undergo optical transformation as they age. This process is influenced by several factors, including particle size. To investigate the lensing effect, this study introduces a novel method and technique for measuring size-resolved light absorption of particles. The key instrument in this method is a 3-wavelength Cantilever-Enhanced Photoacoustic Spectrometer, which is a fast and sensitive tool that measures absorption directly in the aerosol phase. By coupling the CEPAS with a conventional Differential Mobility Analyzer, particle-size resolved measurements are achieved. Evaluation of the developed system showed a strong correlation (R2 > 0.97) with Mie-modelled light absorption of nigrosin reference particles, paving the way for intriguing new opportunities in future studies.
Stratospheric residence time and the lifetime of volcanic stratospheric aerosols
Authors: Toohey Matthew , Jia Yue , Khanal Sujan , Tegtmeier Susann
Published: October 2024

Abstract. The amount of time that volcanic aerosols spend in the stratosphere is one of the primary factors influencing the climate impact of volcanic eruptions. Stratospheric aerosol persistence has been described in different ways, with many works quoting an approximately 12 month “residence time” for aerosol from large tropical eruptions. Here, we aim to develop a framework for describing the evolution of global stratospheric aerosol after major volcanic eruptions and quantifying its persistence, based on global satellite-based aerosol observations, tracer transport simulations and simple conceptual modeling. We show that the stratospheric residence time of air, which is estimated through passive tracer pulse experiments and is one factor influencing the lifetime of stratospheric aerosols, is strongly dependent on the injection latitude and height, with an especially strong sensitivity to injection height in the first four kilometers above the tropical tropopause. Simulated stratospheric tracer evolution is best described by a simple model which includes a lag between the injection and initiation of removal from the stratosphere. Based on analysis of global stratospheric aerosol observations, we show that the stratospheric lifetime of stratospheric aerosol from the 1991 Pinatubo eruption is approximately 22 months. We estimate the potential impact of observational uncertainties on this lifetime finding it unlikely the lifetime of Pinatubo aerosol is less than 18 months.
Terrestrial Cosmogenic Nuclide depth profiles used to infer changes in Holocene glacier cover, Vintage Peak, Southern Coast Mountains, British Columbia
Authors: Hawkins Adam C. , Goehring Brent M. , Menounos Brian
Published: October 2024

Abstract. The majority of glaciers in North America reached their maximum Holocene downvalley positions during the Little Ice Age (1300–1850 CE), and in most cases, this expansion also destroyed earlier evidence of glacier activity. Substantial retreat in the 20th and early 21st centuries exposed bedrock that fronts many glaciers that may record early-to-mid Holocene exposure and later burial by ice which can be elucidated using multiple-nuclide cosmogenic surface exposure dating. Furthermore, cores of bedrock allow the measurement of cosmogenic nuclide depth profiles to better constrain potential exposure and burial histories. We collected four bedrock surface samples for 10Be and 14C surface exposure dating and shallow bedrock cores from Vintage Peak, in the southern Coast Mountains of British Columbia, Canada. We apply a Monte Carlo approach to generate combinations of exposure and burial duration that can explain our data. Vintage Peak became uncovered by the Cordilleran Ice Sheet between 14.5 and 11.6 ka, though higher reaches on Vintage Peak retained ice until 10–12 ka before retreating to smaller than modern positions. Glaciers on Vintage Peak advanced within 100 m of late Holocene maximum positions around 4–6 ka. Poorly constrained subglacial erosion rates, possible inheritance, and variable mass shielding complicate our ability to more robustly interpret bedrock cosmogenic surface exposure histories. Nine 10Be ages on late Holocene moraines reveal that glaciers reached their greatest Holocene extents ca. 1300 CE. Our results agree with other regional glacier records and demonstrate the utility of surface exposure dating applied to deglaciated bedrock as a technique to help construct a record of Holocene glacier activity where organic material associated with glacier expansions may be absent or poorly-preserved. Further work to increase exposure/burial history modeling complexity may help to better constrain complex exposure histories in glaciated alpine areas.
Modeling fuel-, vehicle-type-, and age-specific CO2 emissions from global on-road vehicles in 1970–2020
Authors: Yan Liu , Zhang Qiang , Zheng Bo , He Kebin
Published: October 2024

Abstract. Vehicles are among the most important contributors to global anthropogenic CO2 emissions. However, the lack of fuel-, vehicle-type-, and age-specific information about global on-road CO2 emissions in existing datasets, which are available only at the sector level, makes these datasets insufficient for supporting the establishment of emission mitigation strategies. Thus, a fleet turnover model is developed in this study, and CO2 emissions from global on-road vehicles from 1970 to 2020 are estimated for each country. Here, we analyze the evolution of the global vehicle stock over 50 years, identify the dominant emission contributors by vehicle and fuel type, and further characterize the age distribution of on-road CO2 emissions. We find that trucks accounted for less than 5 % of global vehicle ownership but represented more than 20 % of on-road CO2 emissions in 2020. The contribution of diesel vehicles to global on-road CO2 emissions doubled during the 1970–2020 period, driven by the shift in the fuel-type distribution of vehicle ownership. The proportion of CO2 emissions from vehicles in developing countries such as China and India in terms of global emissions from newly registered vehicles significantly increased after 2000, but global CO2 emissions from vehicles that had survived more than 15 years in 2020 still originated mainly from developed countries such as the United States and countries in the European Union.

A New Database of Extreme European Winter Windstorms

Published: October 2024

Abstract. European windstorms pose a significant threat to people, infrastructure and the natural environment. Several windstorms in the recent past have caused substantial damages, and losses associated with extreme windstorms may increase with climate change. Characterizing the footprints of destructive windstorms is thus key to providing quantitative estimates of storm-related economic losses. To that end, we have developed a new, publicly available database of extreme European windstorm footprints for the extended winter season during 1995–2015. In contrast to previously compiled European windstorm databases, we include storm footprints derived from four different data sets, rather than a single source: the ERA5 reanalysis, the COSMO-REA6 reanalysis for Europe, the COSMO-Climate Limited-area Mode regional climate model driven by ERA5 on the EURO-CORDEX domain, and simulation output from the same model but on an enlarged Germany domain with higher horizontal resolution. The database includes both the footprints themselves, expressed as the relative daily maximum wind gusts associated with a storm event, and the daily maximum wind gusts in absolute magnitude associated with the footprints. We derived and included the storm footprints associated with the 50 most extreme storms, or Top50 storms, identified within each of the four input data sets. We applied a consistent methodology, the storm loss index, across input data sets for identifying storm footprints and assessing their severity. This enables a direct comparison between the footprints derived from the different input sources, eases future efforts to extend the time record of the database or to include additional input data sets, and enables assessment of uncertainty in the footprints. Moreover, since we derived the Top50 storms from each input on its native horizontal resolution, the database also allows to characterize the impact that horizontal resolution can have on footprint identification and severity assessment. Our database thus supports both the research community and the insurance industry in exploring the data set and resolution dependence of assessments of extreme storm hazards.

Abstract. Geochemical data from ancient marine sediments are crucial for studying palaeoenvironments, palaeoclimates, and elements’ cycles. With increased accessibility to geochemical data, many databases have emerged. However, there remains a need for a more comprehensive database that focuses on deep-time marine sediment records. Here, we introduce the “Deep-Time Marine Sedimentary Element Database” (DM-SED). The DM-SED has been built upon the “Sedimentary Geochemistry and Paleoenvironments Project” (SGP) database with the new compilation of 34,938 data entries from 433 studies, totalling 63,691 entries. The DM-SED contains 2,412,085 discrete marine sedimentary data points, including major and trace elements and some isotopes. It includes 9,271 entries from the Precambrian and 54,420 entries from the Phanerozoic, thus providing significant references for reconstructing deep-time Earth system evolution. The data files described in this paper are available at https://doi.org/10.5281/zenodo.13898366 (Lai et al., 2024).
A landslide runout model for sediment transport, landscape evolution, and hazard assessment applications
Authors: Keck Jeffrey , Istanbulluoglu Erkan , Campforts Benjamin , Tucker Gregory , Horner-Devine Alexander
Published: October 2024

Abstract. We developed a new rule-based, cellular-automaton algorithm for predicting the hazard extent, sediment transport, and topographic change associated with the runout of a landslide. This algorithm, which we call MassWastingRunout (MWR), is coded in Python and implemented as a component for the package Landlab. MWR combines the functionality of simple runout algorithms used in landscape evolution and watershed sediment yield models with the predictive detail typical of runout models used for landslide inundation hazard mapping. An initial digital elevation model (DEM), a regolith depth map, and the location polygon of the landslide source area are the only inputs required to run MWR to model the entire runout process. Runout relies on the principle of mass conservation and a set of topographic rules and empirical formulas that govern erosion and deposition. For the purpose of facilitating rapid calibration to a site, MWR includes a calibration utility that uses an adaptive Bayesian Markov chain Monte Carlo algorithm to automatically calibrate the model to match observed runout extent, deposition, and erosion. Additionally, the calibration utility produces empirical probability density functions of each calibration parameter that can be used to inform probabilistic implementation of MWR. Here we use a series of synthetic terrains to demonstrate basic model response to topographic convergence and slope, test calibrated model performance relative to several observed landslides, and briefly demonstrate how MWR can be used to develop a probabilistic runout hazard map. A calibrated runout model may allow for region-specific and more insightful predictions of landslide impact on landscape morphology and watershed-scale sediment dynamics and should be further investigated in future modeling studies.

Published: October 2024

Abstract. This paper presents the development and application of a deep learning-based method for inverting CO2 atmospheric plumes from power plants using satellite imagery of the CO2 total column mixing ratios (XCO2). We present an end-to-end CNN approach, processing the satellite XCO2 images to derive estimates of the power plant emissions, that is resilient to missing data in the images due to clouds or to the partial view of the plume due to the limited extent of the satellite swath. The CNN is trained and validated exclusively on CO2 simulations from 8 power plants in Germany in 2015. The evaluation on this synthetic dataset shows an excellent CNN performance with relative errors close to 20 %, which is only significantly affected by substantial cloud cover. The method is then applied to 39 images of the XCO2 plumes from 9 power plants, acquired by the Orbiting Carbon Observatory-3 Snapshot Area Maps (OCO3-SAMs), and the predictions are compared to average annual reported emissions. The results are very promising, showing a relative difference of the predictions to reported emissions only slightly higher than the relative error diagnosed from the experiments with synthetic images. Furthermore, the analysis of the area of the images in which the CNN-based inversion extract the information for the quantification of the emissions, based on integrated gradient techniques, demonstrates that the CNN effectively identifies the location of the plumes in the OCO-3 SAM images. This study demonstrates the feasibility of applying neural networks that have been trained on synthetic datasets for the inversion of atmospheric plumes in real satellite imagery of XCO2, and provides the tools for future applications.

Objective: The current study aimed to determine the prevalence of partial edentulism according to Kennedy’s classification and its association to arch, age and gender.
Methods: Data were collected from 358 patients aged 18 to 80 years. Selected patients were grouped according to gender and age (<45, =>45). Intra oral examination for each patient was done. The pattern of partial edentulism according to Kennedy’s classification was determined. Statistical analysis was done using the SPSS V26 statistical program. Chi-square test was used to test for differences in frequency at p-value<0.05.
Results and Conclusion: The rate of class III pattern in maxillary arch was significantly higher than that of mandibular arch. Class I pattern in mandibular arch was significantly higher than that of maxillary arch (25.1% vs 14%, P=0.001). No differences in frequency were found between class II and IV pattern and affected arch. Class IV was the least frequent in both dental arches. Frequency of class I and class II partial edentulism increased with age, while class III was more frequent at young age. Class IV pattern was more frequent among males than females.
Effects of Unilateral, Bilateral and Combined Plyometric Jump Training on Asymmetry of Muscular Strength and Power, and Change-of-Direction in Youth Male Basketball Players

Published: October 2024

This study aimed to compare the effects of unilateral (UT), bilateral (BT), and combined (UBT) plyometric training on muscular strength, power, and change-of-direction performance in youth male basketball players. Sixty-six male youth basketball players (age: 16.1 ± 0.8 years) participated in this randomized experimental study, which lasted 8 weeks with a training frequency of 2 sessions per week. The UT group performed only single-leg plyometric exercises, while the BT group conducted similar plyometric drills using both feet. The UBT group combined both approaches, performing one session of UT and one session of BT each week. The players were evaluated at baseline and after the 8-week period using a force platform for the unilateral countermovement jump test (UCMJ), isometric squat test (IST), isometric knee flexor strength test (KFS), leg land and hold test (LHT), and 5-0-5 tests. The asymmetry between legs per outcome was measured using the symmetry angle. The UT, BT, and UBT all significantly improved outcomes in the IST, UCMJ, KFS, LHT, and 5-0-5 tests (p < 0.05) following the intervention, with no significant differences among the three methods. However, while UT and UBT significantly reduced asymmetries in the tests (p < 0.05), BT increased asymmetries. Only, the UT group showed significant improvements over the control group in asymmetry measures: IST asymmetry (mean difference: 1.2%, p = 0.049), KFS asymmetry (mean difference: 2.5%, p < 0.001), and LHT asymmetry (mean difference: 1.1%, p = 0.013). While there are no substantial differences among UT, BT, and UBT in terms of improvements in unilateral tests and symmetry levels, UT stands out for its effectiveness in enhancing neuromuscular performance and reducing asymmetries among basketball players compared to the control condition. UT was the only method that showed significant benefits in this context. Strength and conditioning coaches might consider incorporating UT, either alone or alongside BT, to optimize individual limb strength and coordination.

En el siguiente artículo estudiamos los tres escenarios eróticos en una de las compilaciones poéticas más extensas en la materia del legado mameluco, es decir, El jengibre penetrante para copular con aquellas que visten el burka del egipcio al-Ḥiŷāzī (m. 1470). El objetivo principal de este trabajo es, en primer lugar, conectar todas las teorías e hipótesis vinculadas a la atribución de la obra, no exentas de cierta polémica investigativa, y encajarla en el corpus literario del poeta egipcio. En segundo lugar, descubrimos el contenido inédito del poemario erótico, examinando de manera precisa sus tres escenarios principales: la exaltación sexual imaginada del poeta ante su amada, la explicación de las distintas posturas de placer, y por último la presencia del coqueteo y la situación de nostalgia tras la separación de los amantes.
Thoughts on the conception of Nature in Byzantium (11th-12th Centuries)
Authors: Lazaris Stavros
Published: October 2024

This paper examines a new way of looking at nature in Byzantium in the 11th and 12th centuries, and how this may have impacted the conception of the individual. This shift in mentalities is studied by analysing several testimonies from this period, as well as other contemporary elements such as a pronounced taste for gardens and hunting. The study of artworks reinforces this perception, which bears witness to the Byzantines' desire to reflect on their place between nature and Creation.
Innovation and Byzantine Alchemy in Context: The Constantinian Solidus and the Chrysopoetic Goal
Authors: Merianos Gerasimos
Published: October 2024

The concept of innovation has not been thoroughly explored in the context of Byzantine science, much less so concerning Byzantine alchemy. This article argues that persisting historiographical biases depicting Byzantium as a stagnant culture also influence perceptions of Byzantine science as anti-innovative. Building on recent advancements in the study of innovation in Byzantine culture broadly, this article first conducts a preliminary examination of the relationship between science and innovation in Byzantium, revealing intriguing dynamics between the concepts of “tradition” and “innovation”. Next, it investigates a case study of innovation in Byzantine alchemy, namely how a monetary and economic innovation, the introduction of the solidus by Constantine the Great, likely influenced the perception of alchemy as primarily a chrysopoetic art. In essence, it explores how an external innovation can impact a scientific field, potentially leading to innovative conceptions and change within it.
Astral Iconography and the Byzantine Study of the Heavens
Authors: Costache Doru
Published: October 2024

Byzantine astral iconography developed from early Christian and ancient visual culture, with the latter undergoing a profound process of “Christianisation.” In turn, the early Christian fascination with stellar imagery went through stages of transformation prompted by various factors. Among these, the influence of neighbouring cultures and the widespread interest in astrology are solidly researched. But recent studies of Byzantine science, including astronomy and astrology, open new avenues of interpretation regarding astral iconography. Accordingly, this article considers the flourishing of astral iconography in Byzantium’s later centuries and in the post-Byzantine era as an outcome of scientific progress. Even so, a fuller understanding of the relevant iconography is impossible without the generous theological worldview of the Byzantines, which also legitimised the rebirth of the astral sciences.
Políticas de valorização do magistério no Brasil: sonho prometido e negado?
Authors: de Lima Tamara , Ussami Ferrari Leite Yoshie
Published: October 2024

É consenso que a valorização do magistério incide diretamente sobre a melhoria da qualidade do trabalho docente e da educação pública. Assim sendo, o objetivo deste artigo consistiu em avaliar a execução das políticas de valorização do magistério pelas redes e pelos sistemas de ensino brasileiras, especificamente aquelas que dizem respeito ao ingresso no magistério, ao piso salarial e aos planos de carreira. Esses três elementos compõem o que se denomina de tripé constitucional de valorização do magistério, mas que tem se convertido no tripé da precarização. O estudo, de abordagem qualitativa, realizou um levantamento e análise de dados oficiais da Educação Básica divulgados pelo Instituto Nacional de Estudos e Pesquisas Educacionais Anísio Teixeira (Inep), especificamente as Sinopses Estatísticas da Educação Básica e o Relatório do 4º Ciclo de Monitoramento das Metas do Plano Nacional de Educação (2014-2024). Os resultados evidenciam avanços nas políticas de valorização do magistério, mas ainda encontram obstáculos para efetivação.

Evidenciamos a importância de se debater com discentes sobre a educação inclusiva para a promoção dos direitos humanos nos processos educacionais. Objetivamos analisar e refletir sobre os princípios dos direitos humanos e seus impactos para uma educação inclusiva, sob o ponto de vista dos discentes no Programa de Mestrado Profissional em Educação Inclusiva (PROFEI). De natureza qualiquantitativa, composto por um questionário com 19 perguntas estruturadas em três eixos: o perfil do estudante do PROFEI; a caracterização da área de atuação; e, por último, reflexões críticas dialogadas sobre direitos humanos como prática inclusiva. A pesquisa foi realizada no período de 11 e 12 de dezembro de 2024 e contou com a participação de 12 discentes, durante a finalização da disciplina de Princípios da Educação Inclusiva em Direitos Humanos. O debate teórico foi refletido pelo viés freiriano. Para a análise dos dados qualitativos, os resultados foram examinados via análise de conteúdo de Bardin (2004) a partir da exploração do material, para que as unidades de significado semelhantes fossem agrupadas, considerando recortes semânticos (temas). Os dados quantitativos foram sistematizados no programa Microsoft Excel, resultando em gráficos e tabelas, sendo posteriormente analisados. Entre os resultados observamos unanimidade entre os participantes pela atuação como docentes da Educação Básica, inseridos numa diversidade cultural, de pensamentos e de contextos educacionais, verificando-se a necessidade de formação continuada. Conclui-se a precisão de se firmar um compromisso com práticas pedagógicas críticas associadas ao currículo, com base na promoção dos direitos humanos a fim de se construir uma educação inclusiva.
A necessidade de uma educação para todos na sociedade haitiana de (1804–1843)
Authors: St Victor Maxo , Martiniak Vera Lucia
Published: October 2024

Este artigo se inscreve nos campos da história e da educação para apresentar uma análise histórica das políticas educacionais no Haiti no período de 1804 a 1843. Ele destacou as tentativas feitas durante esse período pelos primeiros líderes do Haiti para implementar a educação inclusiva. Nessa abordagem, ele também destacou os limites das políticas educacionais implementadas por essas lideranças. O objetivo do estudo foi compreender a importância atribuída à educação na política dos primeiros chefes de Estado haitianos. Para atingir esse objetivo, o estudo faz parte de uma abordagem reflexiva voltada para o materialismo histórico como metodologia de pesquisa. Para uma melhor compreensão do assunto, recorreu-se às constituições haitianas da época, a textos legislativos específicos (portarias, circulares) sobre educação e a estudos prévios de interesse para esta pesquisa. Com base na análise de nossas fontes, nosso argumento confronta uma dicotomia nas políticas educacionais dos primeiros chefes de Estado haitianos. Com base na legislação haitiana, o estudo enfatiza que a questão da educação sempre esteve na obra do legislador haitiano. Mas quando se trata de fazer cumprir as leis educacionais, os líderes não conseguiram estabelecer a educação inclusiva no Haiti. Eles deixam a maioria da população haitiana na mais profunda ignorância.

Authors: Zilong Wang  , Ang Li
Published: October 2024

Large-scale integration of wind power brings new challenges to the frequency stability of traditional power systems. The use of battery has become increasingly mature for frequency control. Recently, battolyser as a brand-new technology that combines the functions of battery and electrolyser, shows higher technical and economic potential owing to its hydrogen production ability. Regarding this, the authors conduct detailed calculation and simulation to quantify its performance in primary frequency control. Results are compared with battery under various wind power penetration ratios and state-of-charge (SoC) conditions. It is shown that battolysers are more competitive in primary frequency control with high share of wind power when it operates at a higher SoC with more expensive electricity.

Published: October 2024

Wind power hybrid is a comprehensive utilization method of new energy, which can greatly reduce energy pollution, but there is also the problem of tidal flow difference, so the power flow regulation of wind power energy is  to be solved at present. In this paper, the digital simulation platform is used to comprehensively judge the grid-connected demand, collect data such as wind speed, power generation and energy storage, and regulate the power flow of the wind power hybrid grid in combination with the problem of wind speed randomness. Secondly, the intelligent control function is used to judge the wind turbine transmission power hybrid grid and the power flow of the distributed power grid to balance the stability of the overall power flow, voltage and current of the wind power hybrid power grid. The results show that the digital simulation cloud platform collects the power flow data of the wind power hybrid power grid, generates abnormal power flow points, and supplements the power flow through alternative methods, and its regulation and control effectiveness is greater than 90%, and the amplitude of maintaining the power flow is between 10~20%. The wind power grid's grid-connected power flow regulation time is within 10s, and there is no damage to the wind turbine and energy storage battery. Therefore, the digital simulation cloud platform can realize the power flow control of the wind power hybrid power grid, maintain its overall stability, and meet the needs of new energy grid expansion.
