ABSTRACT Soil erosion studies using rainfall simulators are generally expensive and time consuming. Thus, the aim of this study was to develop a prototype of an automatic runoff collector, capable of real-time quantifying runoff volume and soil loss in field trials using a rainfall simulator. The used sensors were chosen based on the type A uncertainty computed from different volumes of water and concentrations of sediment. Through specific programming, the runoff volume, sediment concentrations and the time of occurrence of the collections corresponding to each 200 cm³ of runoff were recorded on a micro-SD card. The robustness of the calibration and the programming developed were also evaluated in the Arduino Mega® 2560 microcontroller. The pressure (PSI.420) and turbidity (ST100) sensors were selected for developing the prototype, which was evaluated in the field with the InfiAsper rainfall simulator. Then, the data collected automatically by the sensors were compared to those obtained by manual measurement. The automatic runoff collector equipped with the PSI.420 and ST100 sensors has potential to obtain and store runoff data, and it was effective in evaluating the erosion process, generating mean errors of 12.25 and 13.16% for runoff volume and soil loss, respectively. The proposed prototype has a low cost of manufacture, in addition to optimizing the collection of erosion data in studies with rainfall simulators.

RESUMO Estudos relacionados à erosão do solo usando simuladores de chuva são geralmente onerosos e demorados. Assim, o objetivo deste estudo foi desenvolver um protótipo de coletor automático de escoamento superficial, capaz de quantificar em tempo real o volume de escoamento superficial e a perda de solo em ensaios de campo utilizando um simulador de chuva. Os sensores utilizados foram escolhidos com base na incerteza tipo A calculada a partir de diferentes volumes de água e concentrações de sedimentos. Por meio de programação específica, o volume da enxurrada, as concentrações de sedimentos e o tempo de ocorrência das coletas correspondentes a cada 200 cm³ de enxurrada foram registrados em um cartão micro-SD. A robustez da calibração e a programação desenvolvida também foram avaliadas no microcontrolador Arduino Mega® 2560. Os sensores de pressão (PSI.420) e de turbidez (ST100) foram selecionados para o desenvolvimento do protótipo, o qual foi avaliado em campo com o simulador de chuva InfiAsper. Em seguida, os dados coletados automaticamente pelos sensores foram comparados com os obtidos por medição manual. O coletor automático equipado com os sensores PSI.420 e ST100 tem potencial para obter e armazenar dados de escoamento, e foi eficiente na avaliação do processo erosivo, gerando erros médios de 12,25 e 13,16% para volume de escoamento e perda de solo, respectivamente. O protótipo proposto possui baixo custo de fabricação, além de otimizar a obtenção de dados de erosão em estudos com simuladores de chuva.

ABSTRACT Fresh corn is a highly appreciated vegetable in Brazil; this crop has high added value and profitability when compared to dry corn. Despite the consumer market demand for quality, cultivars are not launched every crop season and there is a small number of cultivars available to growers. This denotes a need for breeding programs focused on generating information and genotypes that can occupy this market niche. The objective of this work was to evaluate the progress of five cycles of intrapopulation recurrent selection in half-sib progenies of fresh corn, in the southwest region of Goiás. A randomized block experimental design was used, with evaluation of 64 progenies of corn half-sib progenies and selection intensity of 30% per cycle, with three replications, in the 2011-2012, 2013-2014, 2015-2016, 2017-2018, and 2020-2021 summer crop seasons. The half-sib progenies of fresh corn exhibited genetic variability through intrapopulation recurrent selection in the different selection cycles, which is still promising for further selections after five cycles, with evaluation of 64 progenies per cycle. The base population from crossings between hybrids for tropical and temperate climates showed to be promising for increasing the genetic base of fresh corn populations, with satisfactory gains over the five cycles, presenting mean heritability between the cycles of approximately 78.9% for relative chlorophyll index, 62.2% for plant height, 75.1% for ear insertion height, 70% for ear diameter, 56.6% for ear length, 71.4% for unhusked ear yield, and 71% for marketable ear yield.

RESUMO O milho fresco é uma hortaliça muito apreciada pelos brasileiros e, além disso, possui alto valor agregado e maior lucratividade, quando comparado aos grãos secos. O mercado consumidor apesar de exigente na qualidade, não é abastecido com novas cultivares a cada safra e com um número ínfimo sendo disponível aos produtores. Assim, existe a necessidade da criação de programas de melhoramento, com o intuito de gerar informações e genótipos capazes de suprir esse nicho de mercado. O objetivo do estudo foi avaliar o progresso da seleção em progênies de meiosirmãos de milho fresco, em cinco ciclos de seleção recorrente intrapopulacional, na região sudoeste de Goiás. O delineamento experimental utilizado foi o de blocos casualizados, com a avaliação de 64 progênies de meios-irmãos e intensidade de seleção de 30% por ciclo, com três repetições, em diferentes safras de verão (2011-2012, 2013-2014, 2015-2016, 2017-2018 e 2020-2021). As progênies de famílias de meios-irmãos de milho fresco apresentaram variabilidade genética por meio de seleção recorrente intrapopulacional nos diferentes ciclos de seleção, com avaliação de 64 progênies por ciclo. A população base de cruzamentos entre híbridos para climas tropicais e temperados mostrou-se promissora para aumentar a base genética de populações de milho fresco, com ganhos satisfatórios ao longo dos cinco ciclos, com herdabilidade média de aproximadamente 78,9% para o índice relativo de clorofila, 62,2% para altura de planta, 75% para inserção da espiga, 70% para diâmetro da espiga, 56,6% para comprimento da espiga, 71,4% para espigas empalhadas e 71% para espigas comerciais entre os ciclos.

Abstract It is repeatedly stressed the need to characterize the extant biodiversity in tropical ecosystems. However, inventory studies are still progressing slowly in dry ecosystems, leading to the underestimation of their true biodiversity and hindering conservation efforts. In this study, we present primary and secondary data, along with an updated list of amphibians and reptiles from two localities in the São Francisco-Gurguéia region in Piauí. Additionally, we compare the species composition between nine areas within the Caatinga, which were sampled using standardized methods over the past ten years, to examine broader spatial patterns of community composition. To survey reptiles and amphibians, we employed similar methods and sampling efforts in two areas within the Serra das Confusões National Park (SCNP) region. Our surveys recorded a total of 73 species of amphibians and reptiles, of which 24 are new distribution records for the SCNP region. Consequently, our findings increase the known herpetofauna in the region to 94 species. Despite their proximity, the two sites in the SCNP region exhibited only 42% similarity in species composition, and they differed significantly from other areas within the Caatinga. Furthermore, even the closer Caatinga areas presented differences in species composition, highlighting the necessity to evaluate biodiversity across the landscape and contribute to understanding biogeographic patterns.

Resumo É repetidamente enfatizada a necessidade de caracterizar a biodiversidade vivente em ecossistemas tropicais. No entanto, os estudos de inventário ainda estão progredindo lentamente em ecossistemas secos, levando à subestimação de sua verdadeira biodiversidade e dificultando os esforços de conservação. Neste estudo, apresentamos dados primários e secundários, juntamente com uma lista atualizada de anfíbios e répteis de duas localidades na região de São Francisco-Gurguéia, do Piauí. Além disso, comparamos a composição de espécies entre nove áreas dentro da Caatinga, que foram amostradas usando métodos padronizados nos últimos dez anos, para examinar padrões espaciais mais amplos de composição da comunidade. Para estudar répteis e anfíbios, utilizamos métodos e esforços de amostragem semelhantes em duas áreas na região do Parque Nacional da Serra das Confusões (PNSC). Nossos levantamentos registraram um total de 73 espécies de anfíbios e répteis, das quais 24 são novos registros de distribuição para a região do PNSC. Consequentemente, nossos resultados aumentam a herpetofauna conhecida na região para 94 espécies. Apesar da proximidade, os dois locais na região do PNSC exibiram apenas 42% de similaridade na composição de espécies e diferiram significativamente de outras áreas dentro da Caatinga. Mesmo áreas mais próximas da Caatinga apresentaram diferenças na composição de espécies, destacando a necessidade de avaliar a biodiversidade em toda a paisagem e contribuir para a compreensão de padrões biogeográficos.

ABSTRACT Objectives: Currently, not much is known about the interactions between voice and growth hormone (GH). We have described large kindred with isolated GH deficiency (IGHD) due to a GHRH receptor mutation, resulting in severe short stature and high-pitched voice. These IGHD individuals have little interest in GH treatment, as they consider themselves “short long-lived people”, rather than patients. Interestingly, they report normal general quality of life, but they rate their Voice-Related Quality of Life (V-RQOL) as low. Here, we assessed the social and auditory-perceptual impacts of artistic-intervention voice therapy with semioccluded vocal tract exercises (SOVTE) and choral singing, on their voices. Material and methods: Seventeen GH-naïve adult IGHD individuals were enrolled in a single-arm interventional pre-post study with 13 weekly sessions of choir singing over 90 days. Outcome measures were V-RQOL scores, self-assessment of voice, and auditory-perceptual analysis (GRBAS scale, G: grade of the severity of dysphonia; R: roughness; B: breathiness; A: asthenia; and S: strain). Results: Marked improvements in total (p = 0.0001), physical (p = 0.0002), and socioemotional (p = 0.0001) V-RQOL scores and in self-assessment of voice (p = 0.004) were found. The general grades of vocal deviation (p = 0.0001), roughness (p = 0.0001), breathiness (p = 0.0001) and strain (p = 0.0001) exhibited accentuated reductions. Conclusions: Voice therapy with semioccluded vocal tract exercises and choral training improved social impact and perceptual voice assessments in IGHD subjects and markedly improved their voice-related quality of life. This is particularly important in a setting where GH replacement therapy is not widely accepted.

Abstract: COVID-19 rapidly spread across the world in an unprecedented outbreak with a massive number of infected and fatalities. The pandemic was heavily discussed and searched on the internet, which generated big amounts of data related to it. This led to the possibility of attempting to forecast coronavirus indicators using the internet data. For this study, Google Trends statistics for 124 selected search terms related to pandemic were used in an attempt to find which keywords had the best Spearman correlations with a lag, as well as a forecasting model. It was found that keywords related to coronavirus testing among some others, such as “I have contracted covid”, had high correlations (≥0.7) with few weeks of lag (≤4 weeks). Besides that, the ARIMAX model using those keywords had promising results in predicting the increase or decrease of epidemiological indicators, although it was not able to predict their exact values. Thus, we found that Google Trends data may be useful for predicting outbreaks of coronavirus a few weeks before they happen, and may be used as an auxiliary tool in monitoring and forecasting the disease in Brazil.

Abstract: En | Text: En | PDF: En

ABSTRACT Irrigation is essential for the development of crops in regions with scarcity or irregular rainfall distribution, enabling high productivity. However, the use of water resources and electrical energy leads to a concern with irrigation efficiency. Pressure demand varies during the operations of irrigation systems and the appropriate pressure can be regulated by variable-frequency drives for the power supply of the motor-pump set. This study aimed to analyze the technical and economic feasibility of using a variable-frequency drive to adjust the pressure in subunits of micro-irrigation systems. Laboratory tests were carried out to determine the electrical power consumed in each irrigated subunit for different slopes and the application or not of the variable-frequency drive. Thus, an economic analysis was carried out considering the electricity tariff for group B and rural consumer class, as well as different annual irrigation times. The results showed the potential for energy saving with the use of the variable-frequency drive. Thus, the economic analysis showed that the variable-frequency drive was a better alternative than the dissipative method.

Resumo: O estado de Goiás, no Brasil central, é coberto principalmente pelo domínio do Cerrado, com a Mata Atlântica do Alto Paraná ocupando sua porção centro-sul. Goiás é uma das 20 unidades federativas brasileiras que ainda não possui uma lista de espécies de mamíferos. Neste estudo, apresentamos a primeira lista de mamíferos para o estado. Registramos as espécies de mamíferos com base principalmente na análise de espécimes depositados em coleções científicas, bem como na literatura apresentando material testemunho associado. Listamos 191 espécies pertencentes a 125 gêneros, 31 famílias e 10 ordens, as quais representam 25,2% das espécies de mamíferos que ocorrem no Brasil. As ordens mais especiosas foram Chiroptera (90 spp.), seguida pelas ordens Rodentia (43 spp.), Carnivora (19 spp.) e Didelphimorphia (17 spp.), com as demais ordens respondendo por uma porção menor da diversidade: Cetartiodactyla (7 spp.), Cingulata (7 spp.), Primates (4 spp.), Pilosa (2 spp.), Lagomorpha (1 sp.) e Perissodactyla (1 sp.). Um total de 28 espécies (14,7%), principalmente representadas por mamíferos de médio e grande porte, estão ameaçadas nacionalmente e 12 (6,3%) encontram-se globalmente ameaçadas. Nossos resultados indicaram grandes porções do estado ainda não devidamente pesquisadas em relação aos seus mamíferos, com informações escassas e fragmentadas, principalmente no que diz respeito à sua porção noroeste. Discutimos a riqueza de espécies, a distribuição e o estado de conservação dos mamíferos do estado de Goiás nos cenários nacional e regional. Ressaltamos a importância da realização de inventários que utilizem técnicas complementares de amostragem, incluindo a coleta de material testemunho, proporcionando a obtenção de dados cariotípicos, moleculares, morfológicos, parasitológicos e ecológicos. Estas informações são a base de estudos integrativos, os quais aumentam nossa compreensão a respeito da riqueza e diversidade atual dos mamíferos. O conhecimento a respeito da distribuição da riqueza de espécies em Goiás é essencial para embasar estratégias de conservação, tão necessárias em áreas que vem sofrendo com a perda e fragmentação de seus hábitats naturais, como a porção centro-sul do estado.

Abstract: The state of Goiás, in central Brazil, is covered mainly by the Cerrado domain, with the Alto Paraná Atlantic Forest occupying its central-southern portion. Goiás is one of the 20 Brazilian federative units without a mammal checklist. In this study, we provide the first checklist of mammals from Goiás state. We recorded mammal species based primarily on the analysis of specimens housed in scientific collections as well as on literature with associated voucher material. We listed 191 mammalian species belonging to 125 genera, 31 families and 10 orders, which represents 25.2% of the mammal species occurring in Brazil. The most speciose orders were Chiroptera (90 spp.), followed by Rodentia (43 spp.), Carnivora (19 spp.) and Didelphimorphia (17 spp.). The following orders accounted for a smaller portion of the state diversity: Cetartiodactyla (7 spp.), Cingulata (7 spp.), Primates (4 spp.), Pilosa (2 spp.), Lagomorpha (1 sp.), and Perissodactyla (1 sp.). A total of 28 species (14.7%), mainly represented by medium and large-sized mammals, are nationally threatened while 12 (6.3%) are globally threatened. Our results indicate great portions of the state lacking a proper survey of mammals, especially the northwestern portion. We discuss species richness, distribution and conservation status of the mammals of Goiás state in national and regional scenarios. We highlight the need for mammal inventories based on complementary survey techniques with the collection of vouchers in order to provide karyologic, molecular, morphologic, parasitologic, and ecological data. These informations are the basis for integrative studies that lead to the understanding of current mammalian richness and diversity. Indeed, knowledge on species richness distribution in the state will guide conservation strategies, especially in areas undergoing habitat loss and fragmentation, such as the central-southern portion of Goiás.

RESUMO O acesso à informação e as abordagens interculturais no setor da saúde são essenciais para eliminar as desigualdades no acesso aos serviços de saúde. Os modelos interculturais, como as medicinas tradicionais, complementares e integrativas (MTCI), são uma parte importante da atenção à saúde na maioria dos países e frequentemente contribuem para ampliar o acesso à atenção primária. Apesar do reconhecimento legal e da existência de políticas para a integração das MTCI nos sistemas de saúde, a sua contribuição para a saúde, o bem-estar e a atenção centrada nas pessoas para alcançar a saúde universal ainda é subestimada. Este artigo apresenta o progresso (de 2017 a 2020) alcançado pela Biblioteca Virtual em Saúde especializada em MTCI (BVS MTCI Américas), uma iniciativa criada como ferramenta para reduzir as disparidades na produção e no acesso a informações validadas sobre as MTCI. Realizando um trabalho colaborativo em rede, a BVS MTCI Américas contribui para a democratização da saúde, o acesso a dados científicos verificados, a visibilidade dos conhecimentos não convencionais, o fortalecimento das capacidades de pesquisa e a troca de experiências para a tomada de decisões bem informada.

ABSTRACT Access to information and intercultural approaches in the field of health are essential for the elimination of inequities in health access and care. Intercultural models such as traditional, complementary, and integrative medicine (TCIM) are an important part of health care in most countries and often contribute to expanding access to primary health care. Despite legal recognition and policies to integrate TCIM into health systems, their contribution to health, well-being, and people-centered care to achieve universal health is still underestimated. This article presents the progress (2017-2020) achieved by the Virtual Health Library specialized in the TCIM (VHL TCIM Americas), an initiative created as a tool to reduce the gaps in the production and access to validated information on TCIM. Through collaborative network work, VHL TCIM Americas contributes to the democratization of health, access to verified scientific data, visibility of non-conventional knowledge, strengthening of research capacities, and exchange of experiences for informed decision-making.

RESUMO A água é um elemento essencial à vida e empregada em diversas atividades humanas, todavia, em função do montante utilizado na agricultura e do aumento de área irrigada, o uso sustentável deste recurso tem se tornado uma preocupação mundial. Neste estudo foram avaliados os dados dos Censos Agropecuários publicados pelo Instituto Brasileiro de Geografia e Estatística (IBGE) de 1960 a 2017, com relação às regiões e aos métodos de irrigação, sendo realizada uma análise detalhada entre as informações dos Censos de 2006 e 2017. Houve aumento na área irrigada no Brasil em todas as regiões geográficas, atingindo 6,9 milhões de hectares em 2017. Os métodos de irrigação por aspersão são os mais utilizados, com 48% da área irrigada, seguido pela irrigação localizada (24,4%) e superfície (22,3%). O gotejamento é o sistema mais empregado em estabelecimentos de até 50 ha (617.423 ha), seguido da aspersão convencional (514.893 ha), enquanto o pivô central é o que se destaca em áreas acima de 50 ha (1.362.828 ha). A região Sudeste (38,6%) e os Estados do Rio Grande do Sul (20,4%), Minas Gerais (16,6%) e São Paulo (16,0%) se destacam como os de maior área irrigada do país. O Estado de Minas Gerais apresentou o maior crescimento de área irrigada no período 2006-2017 (116,1%), devido à expansão das áreas irrigadas com pivô central.

ABSTRACT Water is an essential element to life and used in various human activities. However, because of the amount used in agriculture and the increase in irrigated area, the sustainable use of this resource has become a worldwide concern. In this study, data from the Censuses of Agriculture published by the Instituto Brasileiro de Geografia e Estatística (IBGE) from 1960 to 2017 were evaluated in relation to the regions and irrigation methods, performing a detailed analysis between the data from the 2006 and 2017 Censuses. There was an increase in irrigated area in Brazil in all geographic regions, reaching 6.9 million hectares in 2017. Sprinkler irrigation methods are the most used, with 48% of the irrigated area, followed by localized irrigation (24.4%) and surface irrigation (22.3%). Drip irrigation is the most used system in establishments up to 50 ha (617,423 ha), followed by conventional sprinkler (514,893 ha), while the center pivot stands out in areas larger than 50 ha (1,362,828 ha). The Southeast region (38.6%) and the states of Rio Grande do Sul (20.4%), Minas Gerais (16.6%) and São Paulo (16.0%) stand out as the ones with the largest irrigated area in the country. The State of Minas Gerais showed the highest growth of irrigated area in the 2006-2017 period (116.1%), due to the expansion of areas irrigated with center pivot.

Abstract To determine the chemical composition and digestibility of insect meal for poultry made from the larvae of Tenebrio molitor (TL) and nymphs of Gryllus assimilis (GAN) a total excreta collection test was carried out, substituting 20% of the reference diet with each type of meal. The meals presented 6074 and 5975 kcal/Kg of gross energy, with 49.34% and 52.66% protein for TL and GAN respectively. The most nutrient digestibility was less than 65%, except for energy and ether-extract digestibility in the meal from Tenebrio molitor larvae, which were over 70%. The meals under analysis can be used as a source of nutrients in poultry diets.

RESUMO O estudo foi realizado com objetivo de avaliar a produção de sedimentos, a infiltração da água e o escoamento superficial em um Argissolo Vermelho-Amarelo sob chuvas simuladas com erosividades semelhantes, mas com distintas combinações de intensidade de precipitação (Int) e duração (Dur). As chuvas foram aplicadas após o preparo do solo e no período de agosto a setembro de 2017 em Seropédica, RJ, Brasil. Utilizando um programa computacional, os tratamentos foram definidos a partir do cálculo da erosividade para uma chuva de 60 mm h-1 e 60 min de duração, resultando nas demais combinações de Int e Dur: 44,5 mm h-1 e 106 min; 53,5 mm h-1 e 78 min; 66,9 mm h-1 e 48 min; e 76,5 mm h-1 e 38 min, em delineamento inteiramente casualizado com cinco repetições. A produção de sedimentos variou de 2,17 a 6,11 g m-2, respectivamente, nos tratamentos com Int 53,5 mm h-1 e Dur 78 min e Int 44,5 mm h-1 e Dur 106 min. As taxas de infiltração estáveis (mm h-1) foram de 21,6; 37,7; 31,4; 29,5; e 22,4, respectivamente, nos tratamentos Int 44,5 mm h-1 e Dur 106 min; Int 53,5 mm h-1 e Dur 78 min; Int 60,4 mm h-1 e Dur 60 min; Int 66,9 mm h-1 e Dur 48 min; e Int 76,5 mm h-1 e Dur 38 min. As diferentes combinações de intensidade de precipitação e duração das chuvas com erosividade semelhante alteram a produção de sedimentos, mas não influenciam significativamente o escoamento superficial e a infiltração da água no solo.

ABSTRACT The study was carried out to evaluate sediment production, water infiltration and surface runoff in an Ultisol under simulated rainfalls with similar erosivity, but different combinations of intensity (Int) and duration (Dur). The rainfalls were applied after soil tillage in the period from August to September 2017, in Seropédica, RJ State, Brazil. Using a computer program, the treatments were defined from the erosivity calculated for a rainfall with intensity of 60 mm h-1 and duration of 60 min, resulting in the other combinations of Int and Dur: 44.5 mm h-1 and 106 min; 53.5 mm h-1 and 78 min; 66.9 mm h-1 and 48 min; and 76.5 mm h-1 and 38 min, in a completely randomized design with five repetitions. Sediment production varied from 2.17 to 6.11 g m-2, respectively, in the treatments with Int 53.5 mm h-1 and Dur 78 min and Int 44.5 mm h-1 and Dur 106 min. Stable infiltration rate (mm h-1) were 21.6, 37.7, 31.4, 29.5, and 22.4, respectively, in the treatments Int 44.5 mm h-1 and Dur 106 min; Int 53.5 mm h-1 and Dur 78 min; Int 60.4 mm h-1 and Dur 60 min; Int 66.9 mm h-1 and Dur 48 min; and Int 76.5 mm h-1 and Dur 38 min. The different combinations of intensity and duration of rainfalls with similar erosivity change sediment production, but do not significantly influence surface runoff and water infiltration in the soil.

Resumo Analisamos a composição da dieta de Monodelphis domestica (Wagner, 1842) em uma área de campos rupestres no sudeste brasileiro, entre outubro de 2015 e dezembro de 2016. Também avaliamos se existem diferenças na dieta de acordo com a massa corporal, sexos e estações do ano. Obtivemos 70 amostras fecais de 29 indivíduos e 5 categorias de itens alimentares foram identificadas (artrópodes, vertebrados, sementes, flores e partes vegetativas de plantas). Monodelphis domestica apresentou uma dieta especializada consumindo principalmente artrópodes (registrados em 100% das amostras). As amostras também apresentaram partes vegetativas (folhas e caules), flores e pequenos vertebrados (escamas e ossos fragmentados de lagartos, serpentes e aves). A espécie mostrou variação sazonal na dieta, consumindo uma alta proporção de artrópodes, pequenos vertebrados, e partes vegetativas de plantas durante os meses chuvosos. Houve também diferença intersexual na composição da dieta, com machos consumindo um espectro mais amplo de itens do que as fêmeas. Nossos resultados contribuem para a compreensão da ecologia alimentar das cuícas-de-cauda-curta, e representa o primeiro estudo específico sobre a dieta de didelfideos em campos rupestres.

Abstract We analyzed the diet composition of Monodelphis domestica (Wagner, 1842) distributed in a high-altitude rocky habitat (campo rupestre) in Southeastern Brazil, between October 2015 and December 2016. We also evaluated whether there are diet differences depending on body mass, sex and seasons. We collected 70 fecal samples of 29 M. domestica specimens and recorded five food categories (arthropods, vertebrates, seeds, flowers and plant vegetative parts). Monodelphis domestica presented a specialized diet, the specimens mainly fed on invertebrates (founded in 100% of the samples). The samples also presented plant vegetative parts (leaves and stems), flowers and small vertebrates (scales and fragmented bones of lizards, snakes and birds). The species showed seasonal diet variations and consumed large portions of arthropods, small portions of vertebrates and plant vegetative parts during the rainy season. Intersexual differences influenced the diet composition: the range of food items consumed by males was wider than that ate by females. Our findings helped better understanding the food ecology of short-tailed opossums, besides being the first study about the diet of a didelphid species distributed in high-altitude rocky habitats.

ABSTRACT Prostate cancer is the second most common cancer and the fifth leading cause of cancer deaths. In Brazil, it is likewise the second most common cancer among men, second only to non-melanoma skin cancers. The aim of this consensus is to align different opinions and interpretations of the medical literature in a practical and patient-oriented approach. The first Brazilian Consensus on the Treatment of Advanced Prostate Cancer was published in 2017, with the goal of reducing the heterogeneity of therapeutic conduct in Brazilian patients with metastatic prostate cancer. We acknowledge that in Brazil the incorporation of different technologies is a big challenge, especially in the Sistema Único de Saúde (SUS), which allows for the disparity in the options available to patients treated in different institutions. In order to update the recommendations and to make them objective and easily accessible, once more a panel of specialists was formed in order to discuss and elaborate a new Brazilian Consensus on Advanced Prostate Cancer. This Consensus was written through a joint initiative of the Brazilian Society of Clinical Oncology (SBOC) and the Brazilian Society of Urology (SBU) to support the clinical decisions of physicians and other health professionals involved in the care of patients with prostate cancer.

RESUMO Objetivou-se neste trabalho avaliar a produção de girassol de corte em resposta a diferentes volumes de água e substratos, constituídos de solo e fibra de coco. Foram realizados dois experimentos simultâneos em casa de vegetação, localizada no setor de Horticultura da Universidade Federal Rural do Rio de Janeiro (UFRRJ), Seropédica - RJ, Brasil (22º 48’ S, 43º 41’ W e altitude de 33 m), entre abril e junho de 2016. A aplicação de água foi realizada por meio do Acionador Automático para Irrigação (AAI), possibilitando a aplicação de diferentes volumes (33, 67 e 133% da capacidade de retenção do substrato) em relação ao tratamento controle (100%). Os substratos utilizados foram 1/3 de fibra de coco e 2/3 de solo (v/v) (Experimento 1), e 2/3 de fibra de coco e 1/3 do solo (v/v) (Experimento 2). O delineamento experimental utilizado foi o inteiramente casualizado, com 5 repetições. O tratamento referente a 100% do volume aplicado pelo AAI possibilitou o melhor crescimento do girassol, proporcionando o aumento de renda potencial obtida com hastes em melhor padrão de comercialização de acordo com os preços praticados.

ABSTRACT This study aimed to evaluate the production of cut sunflower in response to different water volumes and substrates, composed of soil and coconut fiber. Two simultaneous experiments were conducted in greenhouse, located in the Horticulture Sector of the Federal Rural University of Rio de Janeiro (UFRRJ), Seropédica - RJ, Brazil (22º 48’ S, 43º 41’ W and altitude of 33 m), between April and June 2016. Water was applied by an Simplified Irrigation Controller (SIC), allowing the application of different volumes (33, 67 and 133% of retention capacity of substrate) in comparison to the control treatment (100%). The substrates used were 1/3 of coconut fiber and 2/3 of soil (v/v) (Experiment 1), and 2/3 of coconut fiber and 1/3 of soil (Experiment 2). The experimental design was completely randomized, with 5 replicates. The treatment with 100% of the volume applied by the SIC led to best growth of sunflower, increasing the potential income obtained with stems at better marketing standard according to the prices practiced.
