O Cerrado e o Distrito Federal (DF) sofrem com o processo de fragmentação. O lançamento dos nanosatélites PlanetScope representa uma oportunidade de levar o monitoramento ambiental desse bioma a um novo patamar. Nesse estudo, utilizamos mosaicos mensais das estações seca e chuvosa e aplicamos o método de classificação Random Forest. As áreas de treinamento foram coletadas em campo com o uso de uma Aeronave Remotamente Pilotada (RPA). Os resultados mostraram alta precisão na identificação de diferentes tipos de cobertura vegetal (índice Kappa ? 0,835 e índice de similaridade 0,901). Os modelos com mais variáveis apresentaram maior precisão e as imagens classificadas conseguiram captar mudanças na cobertura do solo relacionadas à dinâmica agrícola. Além disso, a importância de cada banda no resultado das classificações pôde ser analisada

Abstract Bisphenol A (BPA) may adversely affect human health by inducing oxidative stress and irreversible damage to cells. Bioactive compounds found in some functional foods, individually or in combination, can attenuate the negative effects of BPA exposure; an example is the multi-supplement containing guarana (Gua), selenium (Se), and L-carnitine (LC) —GSC— which has already demonstrated antioxidant, genoprotective, and immunomodulatory activities. This study aimed to determine the effect of GSC and its constituents on oxidative and genotoxic alterations triggered by BPA exposure in the retinal epithelial cell line. The cells exposed to BPA (0.001, 0.01, 0.1, 1, 3, and 10 µM) to determine the lowest concentration required to induce cyto-genotoxicity. ARPE-19 cells were then concomitantly exposed to the selected BPA concentration, GSC, and its components (Gua, 1.07 mg/mL; Se, 0.178 µg/mL; and LC, 1.43 mg/mL). Flow cytometry, biochemical assays, qRT-PCR, genotoxicity, apoptosis, and cellular proliferation. Based on our results, 10 µM of BPA could induce cyto-genotoxic and oxidative alterations. BPA did not alter the Bcl-2/BAX expression ratio but induced Casp3 and Casp8 overexpression, suggesting that apoptosis was induced mainly via the extrinsic pathway. GSC partially reversed the alterations triggered by BPA in ARPE-19 cells. However, Se had unexpected negative effects on ARPE-19 cells. The multi-supplement GSC may attenuate changes in oxidative and genotoxic markers related to exposure of ARPE-19 cells to BPA. our results revealed that the antioxidant, anti-apoptotic, and genoprotective properties of GSC were not universally shared by its individual, once Se did not exhibit any positive impact.

The recovery and resilience dialogues were introduced by the regulation of the Recovery and Resilience Facility, and the first of such dialogues took place in May 2021. The European Parliament invites the Commission, approximately every two months, to exchange views on matters relating to the national recovery and resilience plans and progress in their implementation. Through an analysis of an original dataset composed of the questions asked by the MEPs in the 10 dialogues held between May 2021 and April 2023, this article provides a systematic empirical assessment of the European Parliament’s capacity to hold the Commission accountable. Drawing on the literature on the economic and monetary dialogues and adapting the operationalisation of key variables to the new instrument, this article shows that the recovery and resilience dialogues are an effective instrument for information exchange and debate, but they serve as a weak instrument of political accountability. Additionally, it casts new light on significant differences between MEPs: South and East European members are considerably more active than members from Northern Europe. At the same time, parliamentarians only occasionally ask questions targeting other member states.

Abstract Monitoring livestock feeding behavior may help assess animal welfare and nutritional status, and to optimize pasture management. The need for continuous and sustained monitoring requires the use of automatic techniques based on the acquisition and analysis of sensor data. This work describes an open dataset of acoustic recordings of the foraging behavior of dairy cows. The dataset includes 708 h of daily records obtained using unobtrusive and non-invasive instrumentation mounted on five lactating multiparous Holstein cows continuously monitored for six non-consecutive days in pasture and barn. Labeled recordings precisely delimiting grazing and rumination bouts are provided for a total of 392 h and for over 6,200 ingestive and rumination jaw movements. Companion information on the audio recording quality and expert-generated labels is also provided to facilitate data interpretation and analysis. This comprehensive dataset is a useful resource for studies aimed at exploring new tools and solutions for precision livestock farming.

This dataset is composed of correlated audio recordings and labels of ingestive jaw movements performed during grazing by dairy cattle. Using a wireless microphone, we recorded sounds of three Holstein dairy cows grazing short and tall alfalfa and short and tall fescue. Two experts in grazing behavior identified and labeled the start, end, and type of each jaw movement: bite, chew, and chew-bite (compound movement). For each segment of raw audio corresponding to a jaw movement we computed four well-known features: amplitude, duration, zero crossings, and envelope symmetry. These features are in the dataset and can be used as inputs to build automated methods for classification of ingestive jaw movements. Cow's grazing behavior can be monitored and characterized by identifying and analyzing these masticatory events.

Reflections on Rural Education cannot be separated from the social context of the struggle for land. Thus, Rural Education is not just pedagogical practice; it is territorialized in search of breaking barriers of latifundio, capital and ignorance. It emerges within the Landless Workers´ Movement (MST in Portuguese) and transcends the aspirations of the education movement for people who live in settlements and camps. In this perspective, this text aims to present the understanding of the institutionalization process of Rural Education by analyzing Pedagogical Course Projects from courses in an Undergraduate Degree in Rural Education. We start from the hypothesis that Field Education, when institutionalized and making it more available beyond the militancy of social movements, does not maintain the essence in which it was created. Analyses were made considering pedagogical, political and geographic dimensions. This research was designed through theoretical and documentary research. The analyses lead us to recognize the Undergraduate degree in Field Education as the most important territory of Rural Education, which, in turn, presents itself as a territory in constant dispute.

With the signing of the EU–UK trade and cooperation agreement in December 2020, the configurations of Brexit have started to become clearer. The first consequences of the UK’s decision to leave the EU have become visible, both in the UK and in the EU. This thematic issue focuses on a relatively under-researched aspect of Brexit—what the UK withdrawal has meant and means for the EU. Using new empirical data and covering most (if not all) of the post-2016 referendum period, it provides a first overall assessment of the impact of Brexit on the main EU institutions, institutional rules and actors. The articles in the issue reveal that EU institutions and actors changed patterns of behaviour and norms well before the formal exit of the UK in January 2020. They have adopted ‘counter-measures’ to cope with the challenges of the UK withdrawal—be it new organizational practices in the Parliament, different network dynamics in the Council of the EU or the strengthening of the Franco-German partnership. In this sense, the Union has—so far—shown significant resilience in the wake of Brexit.

Brexit makes both a direct and an indirect impact on the European Parliament (EP). The most direct consequence is the withdrawal of the 73-member strong UK contingent and the changing size of the political groups. Yet, the impact of Brexit is also felt in more oblique ways. Focussing on the role and influence of the EP in the EU–UK negotiations, and of the British delegation in the EP, this article shows that the process, and not just the outcome of Brexit, has significant organisational implications for the EP and its political groups. Moreover, it also showcases the importance of informal rules and norms of behaviour, which were affected by Brexit well ahead of any formal change to the UK status as a Member State. The EP and its leadership ensured the active involvement of the EP in the negotiating process—albeit in different ways for the withdrawal agreement and the future relationship—and sought to minimise the costs of Brexit, reducing the clout of British members particularly in the allocation of legislative reports.

A Jornada Universitária pela Reforma Agrária (JURA) da Universidade Federal de Uberlândia acontece tradicionalmente através de uma agenda nacional de eventos com esse fim. A intenção deste texto é trazer as reflexões sobre a territorialização do movimento de lésbicas, gays, bissexuais, travestis e transexuais (LGBT) dentro dos movimentos de luta pela terra no Brasil, especialmente os ligados à Via Campesina, tratados em uma roda de conversa promovida por estudantes do tema para os alunos e integrantes dos movimentos sociais da JURA-UFU. Entendendo que a inserção dessa pauta é um processo que está ocorrendo em escala nacional, o objetivo da roda é levantar questões que são recorrentemente invisibilizadas como a pauta das sexualidades camponesas e a vivência LGBT dentro de acampamentos e assentamentos da Reforma Agrária no Brasil.

ABSTRACT Background: A variety of neurological manifestations have been attributed to COVID-19. Objective: To investigate the occurrence of neurological symptoms and neuroimaging findings in patients hospitalized in two Brazilian reference centers. Methods: We performed a retrospective cohort study of patients who had laboratory-confirmed COVID-19 presenting in two hospitals in Brazil between March 4 and July 7, 2020, who underwent brain imaging. Results: We recorded 1,359 patients with laboratory-confirmed COVID-19. Brain imaging was performed in 250 (18.4%) patients with neurological symptoms, and nine of them (3.6%) had acute or subacute ischemic stroke neuroimaging findings. Six of the nine patients initially presented with respiratory symptoms while the other three patients presented to the emergency room with acute stroke signs. Conclusions: We described the neuroimaging findings of patients infected with COVID-19 who presented with neurological symptoms in two major hospitals in Brazil. We reinforce the importance of being aware of cerebrovascular complications, both in severe hospitalized patients and in patients who present to the emergency room with acute neurological symptoms, even in the elderly.

O presente artigo tem como objetivo analisar as contribuições formativas da participação no PIBID Interdisciplinar Educação do Campo para a formação docente dos licenciandos dos cursos de Ciências Sociais, Geografia, História, Letras e Pedagogia - bolsistas do programa entre os anos de 2014 e 2017- no âmbito da Universidade Federal de Uberlândia. Ao final do projeto, constatou-se que o PIBID é um dos programas que mais colaboram com os licenciandos durante seu processo de formação, seja pela necessidade da bolsa ou pelo interesse nas diretrizes do programa. Durante sua execução, forma-se um elo que une horizontalmente o campo de atuação, que é a escola, com as teorias e discussões oriundas da universidade. A modalidade interdisciplinar Educação do Campo expande ainda mais a formação dos licenciandos, pois oferece a oportunidade das práticas educacionais em um ambiente pouco explorado se comparado ao ensino na cidade. Portanto, a presente análise expôs a importância atribuída ao PIBID Interdisciplinar Educação do Campo enquanto projeto que colaborou no processo formativo dos futuros professores, dando ênfase à realidade encontrada nas escolas do campo, contexto geralmente negligenciado nos cursos de licenciatura.

This work presents the results of our Master´s research, which had as general objective to evaluate the reproductive conditions of the family farming in Sangradouro, Araranguá/SC. It is about a rural community located in coastal vector. Its constitution refers to the beginning of the Twentieth century, when families of farmers forged the one that we denominate “traditionality of the community”. At the end of the same century with the modernizing pressures of the Green Revolution and the globalization, changes occured in the territory like rural exodus of young people and introduction of non agricultural activities. Our qualitative research intended to characterize the occured metamorphoses and their implications in the rural territoriality. We traced the community´s profile through semi-structured interviews, selecting parallel between elements of its history and current setting. Our results pointed the constitution of a territory and hybrid territorialities, where there is a new physical and social scenery, in which characteristic features of urban associate to rural agrarian. We registered the ageing population and the difficult about the generational succession of family farming. We identified that pluriactivity and multi-yields mark the family dynamics, especially for the role of young people and social security policy. The agricultural lands of Sangradouro are approaching the transmutation into housing and leisure lands.

doi: 10.12957/geouerj.2017.23398 From the papers published in the annals of the National Agrarian Geography Meeting (ENGA), a qualitative analysis ofthe incorporation of the Agroecology thematic in the context of geography was made, comprising the manners and waysin which Agrarian Geography interrelates with Agroecology. Since the 2004 edition, where it first appeared as workingtheme, it was observed a diversity of themes being incorporated into the discussion, though it is possible to establishsome typologies related to various perspectives in which the works were built. In order to better divide the work intowider axles, they were established the typologies of Agroecology and Traditional Communities, Agroecology and Ruraleducation / School, Agroecology and the Struggle for Land / Land Reform, Agroecology and Technical andMethodological Foundations, and Agroecology and Experiences and Case Studies were established. This thematicappears in Agricultural Geography still in the 1990s, due to the paucity of a series of questions about the prevailingmodel in agriculture, and the works published in ENGA recent editions demonstrate the consolidation and growth of thedebate within the geography.

A bacia hidrográfica do Alto Descoberto, principal fonte de água e responsável por 60% do abastecimento agrícola do Distrito Federal, vem sofrendo intensas alterações no uso da terra nos últimos anos, fazendo-se necessário seu monitoramento. No âmbito da classificação de imagens de satélite, a Classificação Orientada ao Objeto – OBIA (Objetc Based Image Analysis) vem ganhando importância. As técnicas utilizadas pela OBIA possuem uma nova abordagem, promovendo uma classificação baseada em objetos identificáveis na imagem, ao invés de pixels isolados. Nesse contexto, o presente trabalho apresenta um mapa de uso e cobertura do solo da bacia hidrográfica do Alto Descoberto, obtido por meio de técnicas de OBIA com base em uma imagem obtida pelo satélite Landsat – 8 e uso exclusivo de softwares livres. As etapas desenvolvidas foram pré-processamento, segmentação, classificação por meio de amostras de treinamento e regras de decisão, e avaliação de qualidade. O resultado da classificação mostrou-se satisfatório, apresentando índices Kappa e Tau de 68,45% e 74,88%, respectivamente.

ABSTRACT The study of small reservoirs with low suspended sediment concentration (CSS) is still a challenge for remote sensing. In this work we estimate CSS from the optical properties of water and orbital imagery. Campaigns were carried out at selected dates according to the calendar of sensor passages, rainfall seasonality and hydrograph of the reservoir for the collection of surface water samples and field spectroradiometry. The calibration between CSS and spectral behavior generated CSS estimation models from MODIS and Landsat 8 data, allowing investigation of their temporal and spatial behavior. The MODIS model generated a time series of CSS from 2000 to 2017, presenting R2 = 0.8105 and RMSE% = 39.91%. The Landsat 8 model allowed the spatial analysis of CSS, with R2 = 0.8352 and RMSE% = 15.12%. The combination of the proposed models allowed the temporal and spatial analysis of the CSS and its relationships with the rainfall regime and the quota variation of the Descoberto reservoir (DF). The results showed that the use of orbital data complements the CSS information obtained by the traditional methods of collecting and analyzing water quality in low CSS reservoirs.

O presente artigo apresenta os resultados obtidos no projeto "Formação continuada de professores de Geografia e sua relação com Educação do Campo no município de Uberlândia-MG", que objetivou inserir a discussão da Educação do Campo com alunos de cursos de licenciatura da Universidade Federal de Uberlândia (UFU) e professores da rede municipal de ensino, na perspectiva da formação continuada, buscando compreender os limites e as possibilidades de inserção dessa modalidade educacional no município de Uberlândia. Portanto, esses foram os pressupostos que nortearam a construção, bem como a execução do curso no âmbito da UFU.

INTRODUCTION: Currently in orthodontic diagnosis, besides the lateral cephalometric analysis which evaluates the anteroposterior and vertical direction, the frontal analysis may be added, leading us to another important dimension in space: the transverse dimension. OBJECTIVE: Few longitudinal samples with the frontal radiograph were published, so this cephalometric study was designed to correlate the transversal and vertical measures by Ricketts-Faltin frontal analysis into two radiographic times. METHODS: The sample consisted of 45 Brazilian children, 25 girls and 20 boys, all presenting mixed dentition, with balanced facial aesthetics and no previous orthodontic/orthopedic treatment. The initial average age (T1) was 7.7 years and the final (T2) 13.3 years. The measurements evaluated were: FTD, MxTD, NTD, LITD, MdTD (transversal), OVD and TVD (vertical). RESULTS: All transversal measures were positively correlated with a medium or high correlation with each other and the vertical measurements; only LITD presented a low correlation with these measurements. CONCLUSION: It was concluded that the face has interdependent regions and that this feature remains with growth.INTRODUÇÃO: atualmente no diagnóstico ortodôntico, além da análise cefalométrica lateral - que avalia os sentidos anteroposterior e vertical -, deve-se acrescentar a análise no sentido frontal, a qual propicia outra dimensão importante no espaço, a transversal. OBJETIVO: poucas são as amostras longitudinais publicadas utilizando telerradiografias frontais; portanto, o presente estudo cefalométrico teve o intuito de correlacionar as medidas transversais e verticais por meio da análise frontal de Ricketts-Faltin, em dois tempos radiográficos. MÉTODOS: a amostra constou de 45 crianças brasileiras, sendo 25 meninas e 20 meninos, todos apresentando dentição mista, com perfil harmonioso e sem nunca terem sido tratadas ortodonticamente e/ou ortopedicamente. A idade média inicial (T1) foi de 7,7 anos e a final (T2) de 13,3 anos. As medidas avaliadas foram: DTF, DTMx, DTN, DTII e DTMd (transversais); DVO e DVT (verticais). RESULTADOS: todas as medidas transversais estavam correlacionadas positivamente, em grau médio ou forte, entre si e com as medidas verticais; somente DTII estava correlacionada em grau fraco com essas medidas. CONCLUSÃO: concluiu-se que a face possui regiões interdependentes, e assim mantém-se mesmo com o crescimento.

Nos últimos anos discute-se a necessidade de se pensar uma Educação do Campo como possibilidade de reconhecimento dos saberes e fazeres e a busca pela emancipação dos sujeitos do campo. O livro didático é um dos recursos mais utilizados nas escolas públicas brasileiras e, nesse contexto, o trabalho buscou mostrar como o livro didático de Geografia poderia contribuir na construção da Educação do Campo – em específico, no município de Uberlândia-MG. O objetivo geral consistiu em compreender se e como está ocorrendo a implementação dos livros didáticos de Geografia (PNLD Campo) destinados às escolas rurais no município. Como procedimento metodológico, realizaram-se leituras sobre o ensino de Geografia para os anos iniciais, sobre o livro didático em geral e, em particular, sobre o livro didático de Geografia e a Educação do Campo. Realizaram-se a leitura do documento Guia PNLD Campo 2013 e entrevista com a assessora pedagógica do Ensino Fundamental da Secretaria de Educação. Aplicaram-se de questionários aos professores da escola rural Freitas Azevedo. Conclui-se que livro didático de Geografia pode contribuir na aquisição de conhecimentos para a construção da Educação do Campo, mas é preciso que se faça a capacitação docente e haja uma política de formação continuada voltada para a educação do campo.

Para realizar a referida análise, delimitamos o recorte temporal pós-1990 no qual se acentua a luta pela posse da terra no Rio Grande do Sul e, consequentemente, o processo de instalação dos projetos de assentamentos rurais na região. Assim, torna-se evidente uma nova dinâmica territorial em alguns municípios da Campanha Gaúcha, após o processo de reterritorialização camponesa. Nossa metodologia pautou-se na abordagem qualitativa. A partir dessa premissa, procuramos responder os objetivos propostos. No referencial teórico, discutimos a importância da incorporação do conceito de Territorialização-Desterritorialização-Reterritorialização (TDR) embasados nos estudos sobre as diferentes territorialidades promovidas pelos movimentos sociais no campo. Utilizamos também o conceito de identidade territorial, pois na análise em questão são conceitos que se complementam. Isso se justifica porque identificamos claramente duas identidades territoriais presentes nas expressões da reterritorialização camponesa na região. Detectamos que a configuração territorial da Campanha Gaúcha nesse início de século XXI é bastante complexa em função da heterogeneidade de atores envolvidos na trama territorial, apresentando-se como um espaço regional onde as rugosidades são evidentes, mas com transformações significativas em curso. Estamos, portanto, diante de uma nova territorialidade camponesa que expressa suas manifestações socioculturais por meio de elementos materiais e imateriais, promovendo uma metamorfose no espaço latifundiário regional. A partir dessas novas relações, os camponeses reterritorializados expressam nesse novo território sua identidade territorial.

The organization of the space agrarian gaúcho possesses specified associated its partner-spaceformation, where the farming of rice and of soy they are configured seemingly in territories different.Historically the rice is produced in the south half, tends as characteristics the lease of the earth, hightechnological pattern and to be destined to the internal market. While the soy in the north half isproduced in own lands, also with high technological pattern, and destined mainly for the externalmarket. However, in function of the oscillations of the market, associated the drop of the price of therice, the soy has been occupying significant spaces in typical areas of production of rice.

O presente artigo tem por objetivo refletir sobre os desafios da educação do campo noTriângulo Mineiro, região que nas últimas décadas caracterizou-se por uma intensaterritorialização do agronegócio, ao mesmo tempo em que avançaram as reivindicações dosmovimentos sociais do campo. Portanto, o caráter modernizador tornou invisível ademanda por outra educação, ou seja, uma educação do campo em consonância com osanseios da população rural.

RESUMO: Nos últimos anos, no Triângulo Mineiro, em especial no município de Uberlândia, em função da significativa atuação dos movimentos sociais no campo, os acampamentos de trabalhadores sem-terra ganharam significativo destaque na paisagem como símbolos da luta pela reforma agrária. Nesse contexto, o projeto de extensão "A Geografia vai ao acampamento" tem como objetivo possibilitar a melhoria do ensino de Geografia para alunos do ensino fundamental residentes em acampamento de trabalhadores sem-terra, bem como aproximar os futuros licenciados das múltiplas possibilidades do processo de ensino-aprendizagem. Com a experiência da Escola Itinerante existente nos acampamentos do MST, esperamos aproximar ainda mais a universidade da sociedade. UNITERMOS: Educação no campo. Ensino de Geografia. Acampament. Education on field: experiences from the extension project "Geography goes to camp" ABSTRACT: In recent years, in the Triângulo Mineiro, particularly in Uberlândia, due to the significant role of social movements in the field, the camps of landless workers gained significant prominence in the landscape as symbols of the struggle for agrarian reform. In this context, the extension project "A Geografia vai ao Acampamento" (Geography goes to camp) aims to enable the improvement of geography teaching to elementary students living in the camp of landless and near future licensees of the manifold possibilities of the process of teaching and learning. With the experience of existing Itinerant School in MST camps, we hope to get even closer to the university in society. KEYWORDS: Education on field. Geography teaching. Camp.
