EFEITO DO PERCENTUAL DE PTFE NA ENERGIA ABSORVIDA POR DOSÍMETROS DE CaSO4:Dy Isabella Pereira Tobias1, Lucas Wilian Gonçalves de Souza1, Samara Pavan Souza1, William Souza Santos1, Ana Paula Perini1,2, Lucio Pereira Neves1,2 1Programa de Pós-Graduação em Engenharia Biomédica, Universidade Federal de Uberlândia, Uberlândia, Brasil. 2Instituto de Física, Universidade Federal de Uberlândia, Uberlândia, Brasil. 1. INTRODUÇÃO O dosímetro de radiação é um dispositivo, instrumento ou sistema que mede, direta ou indiretamente, as doses de radiação ionizante [1]. O sulfato de cálcio dopado com disprósio (CaSO4:Dy) possui várias aplicações no campo de dosimetria das radiações ionizantes devido à sua facilidade de preparação, em comparação com muitos outros dosímetros termoluminescentes (TL) [2]. 2. MATERIAIS E MÉTODOS O Monte Carlo N-Particle 6 (MCNP6) é um código em Fortran desenvolvido pelo Los Alamos National Laboratory (LANL) para a simulação do transporte e interação da radiação com a matéria [3]. A energia depositada em cada dosímetro em MeV/g/partícula foi contabilizada utilizando-se o Tally F6 do código MCNP6. Foram simuladas 1x109 histórias para garantir incertezas menores que 1%. O espectro de raios-X foi gerado no programa SRS 78 [4] com os seguintes parâmetros: energia de 90 keV, ângulo anódico 12°, filtração de 2,5 mmAl e campo circular com 15 cm de raio. Tabela 1. Densidade do dosímetro em função do percentual de PTFE. 3. RESULTADOS E DISCUSSÕES Os resultados de energia absorvida por cada dosímetro CaSO4:Dy+PTFE normalizados pela energia absorvida pelo dosímetro de ar são apresentados na Fig. 2. Observa-se que no intervalo entre 10% e 20% de PTFE, a energia absorvida aumenta. Entre 20% e 100% ocorre uma redução da energia absorvida. 4. CONCLUSÃO A resposta relativa do dosímetro para concentrações parciais sob a irradiação de fótons foi que a menor absorção verificou-se para a amostra com maior taxa de PTFE. Embora a melhor resposta do dosímetro ocorreu pra concentrações de PTFE entre 10% a 20%, ainda se fazem necessários estudos adicionais para aferir a utilização desse dosímetro em dosimetria das radiações.

v Citizen collectives for healthcare spread to nearby neighborhoods Kevin Wittenberg, Rense Corten performance Main result 1 Care collectives are spatially clustered, even while accounting for regional attributes Main result 2 Care collectives are not much better predicted than baseline. Political climate may be important Using residuals of a data-driven model, we estimate spatial correlation that cannot be attributed to underlying correlates of collective action. Methods Background Citizens increasingly organize (in)formal care services among themselves in residential communities. We investigate their emergence based on a theoretical frame of diffusion of behavior. To do so, we test whether these care collectives are geographically clustered, while accounting for spurious causes of clustering.

We find support for the notion that citizen collectives can influence collective action in neighboring regions. We combined data- driven techniques and inferential statistics.

Over 2,400 data sets have been put into the public domain. n Our recent challenge is that we have been unable to keep up with the increasing volume of deposits. Therefore, SSJDA built a self-archiving system in February 2023. nNumber of applications: 1,410 (75 applications from international researchers and graduate students around the world) nThe total number of data provisions is 23,800.

ENVIRONMENTAL STUDIES PROGRAM INFORMATION SYSTEM Conﬁgured, Not Coded: Rethinking How the General Public Discovers Environmental Science To better serve the public, the Bureau of Ocean Energy Management’s Environmental Studies Program (ESP) is rebuilding its science dissemination tool, the Environmental Studies Program Information System (ESPIS). The target audience for this tool are users with little knowledge of ocean science and the engaged government agencies. Built on the ArcGIS Online (AGOL) hub, the tool uses large format infographic cards to give users options to browse among four science topics: Physical, Chemical, Biological, and Social Sciences. Under each science topic, the user can select from a dozen or more themes. Under each theme, the user will ﬁnd a templated theme page that uses website widgets to search, sort, and ﬁlter curated lists of research projects, products, and applications. This buildable, sustainable interface enhances the public’s discovery of environmental science information. Title Theme pages have catchy titles that help users navigate from science topics to themes. Introduction When users ﬁrst navigate to the theme page, the header section presents them with this text element, which helps them glean the contents of the theme page. Region Bookmark The region widget enables users to quickly navigate to a predeﬁned map extent and reduces the number of cards in the map section to the ones from the bookmarked region Map The user interacts with tools to browse studies and related content. The user can select a map feature to highlight the corresponding card from a map section list. Studies List These are all the studies that contribute to the theme, and users can interact with all the map section tools to search, sort, and ﬁlter this list. Related Content List These derived products and webpages use a study product and/or combine parts of multiple study products to create value-added scientiﬁc information. When the user selects a related content card, the user actions function highlights the related study product(s). By: Jonathan Blythe (BOEM ESP) and Emily Sandrowicz (NV5, on contract to BOEM) The user can discover all the products resulting from ESP studies that contribute to a theme. If the user ﬁrst selected a card in the map section, then the related study product(s) will automatically highlight. Study Products The user can search, ﬁlter, and sort the list of documents published by the ESP Documents List The user interacts with the list of journal publications by using the search, ﬁlter, and sort tools. Publications List The recommender section includes one or more button widgets that link to similar theme pages, in case users ﬁnd this theme page useful, and so they do not have to navigate back to the science topic theme list in order to ﬁnd these other relevant theme pages Recommender Bureau of Ocean Energy Management Study Studies cards include the study title and program number elements. When the user selects a study card, the user actions function highlights the related study product.

ENTRE O POLÍTICO E O FAMILIAR: DISCURSOS DE ÓDIO E ATRAVESSAMENTOS CONJUNTURAIS Victória Rosa da Silva. Universidade Federal Fluminense. Niterói - Rio de Janeiro. Waldenilson Teixeira Ramos. Fundação de Empreendimentos Científicos e Tecnológicos (FINATEC). Niterói - Rio de Janeiro. Objetivo: Este trabalho se apresenta enquanto um relato de pesquisa que se endereça a refletir sobre a atual conjuntura política no Brasil e as dinâmicas de adoecimento que podem ser provocadas por esta no meio familiar. Metodologia: Parte-se de uma Psicologia Social Crítica, instrumentalizada através das contribuições de pensamentos dos intelectuais: Michel Foucault (2021), Gilles Deleuze e Félix Guattari (2011). Com o auxílio paralelo de notícias brasileiras que informam sobre os acontecimentos de violência no contexto familiar e suas repercussões no âmbito da saúde mental, principalmente nos períodos eleitorais do país. Resultados e Discussão: Em 9 de julho de 2022, Marcelo Arruda foi morto em meio a comemoração familiar de seu aniversário devido a dissonâncias políticas. Ocorreu uma troca de tiros em que, no fim, o assassino de Marcelo foi chutado pelos familiares presentes enquanto estava baleado no chão. A cena choca não só pelas violências presentes, mas pelas profundas feridas psíquicas nos membros familiares que acompanharam o desenrolar do acontecimento. Tal cenário ajuda a ilustrar certa alegoria da realidade vivida por algumas familia brasileiras, o que desvela um quadro sintomático em tempos de polarização extrema do cenário político do país, em que uma discordância entre partidos políticos têm a potencialidade de instigar comportamentos agressivos, violências sem precedentes e adoecimento mental. Não obstante, se evidencia na atual conjuntura brasileira a insurgência da propagação do discurso de ódio, que se apresenta como potencializador desse adoecimento intrafamiliar.
