    Em 1974, o Parecer CFE nº 4089 aprovou a formação do técnico em nível de 2º grau no setor de Nutrição, denominado de Técnico em Nutrição e Dietética, com a descrição deocupação de que “O Técnico em Nutrição e Dietética deve auxiliar o Nutricionista nas tarefas”. Conforme a Resolução CFN Nº 605 de 22 de abril de 2018, estas tarefas podem ser desempenhadasnas áreas de Nutrição em Alimentação Coletiva, Nutrição Clínica, Nutrição em Saúde Coletiva e Nutrição na Cadeia de Produção, na Indústria e no Comércio de Alimentos. Neste relatório se busca descrever as atividades vivenciadas na área de Saúde Coletiva, apontando as dificuldades e aprendizados que foram de extrema importância neste processo em formação. Dentre as atividades realizadas, o auxílio se deu por meio dacoleta de medidas antropométricas, para subsidiar a avaliação nutricional, a ser realizada pelo nutricionista; buscade informações sobre os hábitos e aversões alimentares dos pacientes; e o desenvolvimento de ações de educação alimentar e nutricional para a população atendida,por meio de palestra sobre diabetes e hipertensão. Essas experiências ajudaram a aperfeiçoar as competências do técnico em formação, além de ter fortalecido o seu papel ético e responsável perante a sociedade

    A substituição da vegetação nativa e a sazonalidade climática modificam os parâmetros biofísicos da superfície. Como 50% do Cerrado tem sido convertido em lavouras e pastagens, o objetivo desse estudo foi avaliar a variação temporal de parâmetros biofísicos em áreas nativas e convertidas em uma área de transição entre Cerrado e Pantanal no Mato Grosso. O estudo foi conduzido na Fazenda Experimental da UFMT (15° 51’ 15.23’’ S e 56° 04’ 13.50’’ W) com imagens do sensor TM-Landsat 5 entre abril e setembro de 2011. O Índice de Vegetação da Diferença Normalizada (NDVI), o albedo da superfície (α) e a temperatura da superfície (Ts) foram estimados em áreas de Cerrado strito sensu (CER), pastagem de Brachiaria brizantha (PAS) e mangueiral (MAN). Os maiores valores de NDVI e menores valores de α e Ts foram observados nas áreas mais densamente vegetadas. O Cerrado apresentou menores valores de α e a MAN apresentou maiores valores de NDVI ao longo de todo experimento. A substituição da cobertura nativa da região de transição de Cerrado e Pantanal por vegetação exótica modificou significativamente os parâmetros biofísicos avaliados, com potencial de modificar os balanços de radiação, energia, carbono da superfície. Palavras-chave: desmatamento; sensoriamento remoto; aquecimento regional.   TEMPORAL VARIATION OF BIOPHYSICAL PARAMETERS OF THE SURFACE BY LANDSAT 5 IMAGES IN DIFFERENT SOIL COVERS IN A TRANSITIONAL AREA OF CERRADO AND PANTANAL IN MATO GROSSO   ABSTRACT: The substitution of native vegetation and climatic seasonality modify the surface biophysical parameters. As 50% of the Cerrado has been converted to crops and pastures, the objective of this study was to evaluate the temporal variation of biophysical parameters in native areas and converted into a transition area between Cerrado and Pantanal in Mato Grosso. The study was conducted at the UFMT Experimental Farm (15° 51’ 15.23’’ S e 56° 04’ 13.50’’ W) with TM Landsat 5 images between April and September 2011. The Normalized Difference Vegetation Index (NDVI), and the surface albedo (α) and surface temperature (Ts) were obtained from a Cerrado stricto sensu (CER), a pasture of Brachiaria brizantha (PAS) and a mangrove (MAN). The highest NDVI values and lowest α and Ts values were observed in the most densely vegetated areas. The replacement of the native cover of the Cerrado and Pantanal transition region with exotic vegetation significantly modified the biophysical parameters evaluated, with the potential to modify the radiation, energy and carbon balances of the surface.

    New techniques for manufacturing of biomaterials using additive/substrate manufacturing such as melting laser sintering (SLM) or CAD/CAM milling use micrometric metal powders to build custom parts. CoCrMo alloys are commonly used as biomaterials due to biocompatibility, high corrosion resistance and good mechanical properties. In this work, Cr-Co-based powder was obtained by mechanical alloying of Cr-Co-Mo-W alloy, using different Ball/Powder-Ratios (BPR) and thermal treatments. The powders were deagglomerated and characterized by X-ray diffraction (XRD) and Scanning electron microscopy (SEM). Based on SEM micrographs, the particle size analysis was used to compare the particles spheroidizing degree, using Feret’s diameter. The XRD patterns shown Co(solid-solution) as crystalline phase. The results of particles size indicates a decrease of Feret’s diameter in BPR  (Ball/Powder-Ratio) from 4:1 to 6:1 understanding that from this ratio there is no significant decrease of this relation but there is an average size increase with losses in morphological aspect. The comparison between atomized powders and powder developed in this work indicates that atomized products present relation close to one which indicates there is uniformity in the particles spherical shape. Comparing ground powders from 6:1 ratio (before and after thermal treatment) there is a considerable decrease of Feret’s diameter being it decreased from 1.75 to 1.4, an increase of about 46% in particles spheroidizing.Keywords: Co-Cr-Mo-W alloy, High-Energy Ball Milling, powder morphology; characterization .

    Objective: To evaluate the influence of tooth loss and the use of removable dentures on chewing function and nutritional status of institutionalized elders. Material and Methods: Cross-sectional study with 155 elders from seven long-stay institutions in João Pessoa, Brazil. The participants were classified according to the presence of reminiscent teeth and use of dentures in four levels: toothless, without denture (1); toothless with a complete denture (2); partial toothless without denture (3) and partial toothless with a partial denture (4). Nutritional status was assessed using the Mini-Nutritional Assessment (MNA) instrument and the Body Mass Index (BMI). Swallowing threshold was used for the assessment of masticatory function, using a portion of roasted peanuts (3.7 g). Comparisons among groups were performed using Kruskal-Wallis test with Bonferroni adjustment, considering p<0.05. Results: MNA (p=0.702) and BMI (p=0.884) were not modified in relation to the presence of teeth and denture use. Toothless individuals without dentures had a lower swallowing threshold (p<0.001), whilst partial toothless with dentures had better masticatory function (p>0.05). Conclusion: The presence of reminiscent teeth and the use of dentures do not influence the nutritional status of the elders but interfere with the masticatory function. Prosthetic rehabilitation is desirable for complete toothless individuals

    The purpose of this article is to compare the evolution of COVID-19 in Manaus and Fortaleza, two epicenters of the pandemic in 2020, analyzing legal measures by local governments and levels of social isolation. An algorithm was defined to calculate the Homestay Index (HSI), using data from the Google Mobility Report. The Decree's timeline, the HSI evolution, the incidence of COVID-19 and the number of deaths from March/2020 to January/2021 were analyzed. The population of Fortaleza was exposed to more consistent measures of social distance, than those of Manaus. Longer homestay was observed from March to May 2020 and Fortaleza achieved higher and more lasting levels. As of June 2020, the HSI fell, notably in Manaus, reaching levels below zero in late December. As an aggravating factor, the government decreed ample isolation in Manaus on December 23/2020, but after protests, it repeals it on December 26/2020. A Judicial Decision determines the complete closure in Manaus on January 02/2021, but it was too late: SUS collapses with an exponential increase in deaths. In Fortaleza, the demand for health services is high, but under control. We consider that only the strict application of non-pharmacological measures and mass immunization can prevent further deaths.O objetivo desse artigo é comparar o comportamento do COVID-19 em Manaus e Fortaleza, dois epicentros da pandemia em 2020, analisando medidas legais dos governos locais e níveis de isolamento social. Definiu-se um algoritmo para calcular o Índice de Permanência Domiciliar (IPD), com dados do Google Mobility Report. Analisou-se a linha do tempo dos Decretos, a evolução do IPD, da incidência de COVID-19 e do número de óbitos de março / 2020 a janeiro / 2021. A população de Fortaleza esteve exposta a medidas de distanciamento social mais consistentes que as de Manaus. Maior permanência domiciliar foi observada de março a maio de 2020 e Fortaleza atingiu níveis mais elevados e duradouros. A partir de junho o IPD caiu, sobretudo em Manaus, atingindo níveis abaixo de zero no final de dezembro. Como agravante, o governo decreta amplo isolamento em Manaus em 23/12/2020, mas após protestos, revoga-o em 26/12/2020. Uma Decisão Judicial determina o fechamento completo em Manaus em 01/02/2021, mas foi tarde demais: o SUS entra em colapso com aumento exponencial dos óbitos. Em Fortaleza a demanda por serviços de saúde está elevada, mas sob controle

    Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
