ABSTRACT Shade-tolerant soybean genotypes will allow their greater adoption for use in agroforestry or intercropped systems in tropical and subtropical regions. These genotypes can be obtained from the selection of existing superior genotypes or through breeding programs. This study, was verified such genetic variability and select those genotypes with cultivation potential at reduced levels of photosynthetically active radiation (PAR). Morphophysiological and yield characteristics of 16 soybean genotypes were evaluated in two experiments conducted in a controlled environment and laid in a randomized block design with three replications. Genetic parameters, correlations and genetic diversity were estimated and path analysis was performed. The soybean cultivars used showed genetic variability with a high variation index and heritability, which is advantageous for the selection of superior cultivars. Leaf area showed genotypic correlation and had a direct effect on seed weight per plant, regardless of shading. Additionally, the number of pods, hypocotyl diameter, and leaf area, all indirectly contributed to seed weight per plant regardless of shading. Seven genotypes (NS7780, NS8338, NS7667, NS7901, RK8115, CZ37B43 and 8579RSF) were selected based on genetic gain obtained by the Mulamba and Mock index at the two levels of PAR reduction tested. Furthermore, five of these genotypes (CZ37B43, RK8115, NS7901, NS8338 and 8579RSF) were identified by the Unweighted Pair-Group method Arithmetic Mean, as suitable either as a shaded crop or, as parental materials in breeding programs.

RESUMO Estudo transversal cujo objetivo foi identificar a prevalência e os fatores associados à violência no trabalho (física e/ou verbal) contra residentes multiprofissionais que atuam em um hospital universitário durante a pandemia da Covid-19. Foi desenvolvido um censo, em julho de 2020, com 67 residentes. Dados foram coletados por meio de questionário eletrônico, avaliando-se a violência física e verbal mediante autorrelato. Associações entre a ocorrência de violência vivida durante a pandemia e as variáveis independentes (sociodemográficas, psicoemocionais e atendimento ao paciente com Covid-19) foram analisadas mediante testes estatísticos e Regressão de Poisson (RP) com variância robusta. A prevalência de violência foi de 22,4%. Diferenças entre grupos foram observadas ao comparar as ocupações e o grau de satisfação com a residência, com maior proporção de fisioterapeutas e assistentes sociais, assim como de residentes insatisfeitos entre os que relataram violência (p≤0,005). Após análise de regressão, a violência esteve associada ao aumento da idade (RP=1,25; IC95% 1,12-1,40) e a níveis de ansiedade moderados/graves (RP =2,87; IC 95% 1,12-1,40). Os achados apontam para a necessidade de implementação de medidas institucionais de prevenção e controle da violência no trabalho, considerando os fatores associados durante a pandemia.

ABSTRACT Cross-sectional study which objective was to identify the prevalence and factors associated with workplace violence (physical and/or verbal) against multiprofessional residents working at a Brazilian university hospital during the COVID-19 pandemic. A census was developed in July 2020 with 67 residents. Data were collected through an electronic questionnaire, evaluating physical and verbal violence through self-report. Associations between the occurrence of violence experienced during the pandemic and independent variables (sociodemographic, psycho-emotional, and patient care with COVID-19) were analyzed using statistical tests and Poisson Regression (PR) with robust variance. Differences between groups were observed when comparing occupations and the degree of satisfaction with the residence, with a higher proportion of physical therapists and social workers, as well as dissatisfied residents among those who reported violence (p≤0.005). After regression analysis, violence was associated with increase in age (PR=1.25; 95%CI 1.12-1.40) and moderate/severe anxiety levels (RP=2.87; 95%CI 1.12-1.40). The findings point to the need to implement institutional measures for the prevention and control of workplace violence considering the factors associated with it during the pandemic.

ABSTRACT. The aim of this study was to evaluate the phenotypic variation and diversity of cassava for breeding purposes based on the pasting properties of starch, for food applications. The viscosities of the starches, extracted from 1031 accessions, were obtained using a Rapid Visco Analyzer. The best linear unbiased predictors were calculated for five critical points of the viscograms, which were then used to cluster the accessions based on the discriminant analysis of principal components. The wide phenotypic variation identified from the viscograms reveals the high potential for selection gains, especially for pasting temperature and setback. Certain strong correlations indicate that selection based on a specific viscogram trait can be used for indirect selection (e.g., the correlation between peak viscosity and breakdown [0.85]). The lowest Bayesian information criterion identified five different groups. Groups 3 and 4 exhibited high pasting temperatures, while Groups 3 and 5 exhibited low setbacks. Group 3 also exhibited low viscosity and breakdown. However, we focused on selecting cassava accessions with a high pasting temperature and low setback, as these are the most important traits for industrial applications. The predicted genetic gains from the selection of the top 15 cassava accessions for increasing pasting temperature and decreasing setback were 4.40% and 53.17%, respectively. The increased pasting temperature (~72.89°C) and high amplitude of setback (~600 cP) due to selection can guide the utilization of the cassava germplasm for breeding and provide a basis for further studies to develop varieties with added value, especially in the food industry.

Abstract This paper describes an isogeometric analysis of the boundary element method, called IGABEM, applied to anisotropic 2D plane elastic problems. The Lekhnitskii's anisotropic fundamental solution is used and the singular integral terms is regularized. For the weak singularity kernel, the Telles transform is used. On the other hand, in the strong singularity term, the Singularity Subtraction Technique - SST is used. The shape functions used are the Non-Uniform Rational B-Spline - NURBS. Thus, the same mathematical representation of Computer Aided Design - CAD is used in the implemented computational code. This avoids the generation of meshes and provides an exact representation of most complex geometries. As a reflection of this isoparametric concept, errors from geometric interpolation are excluded, improving numerical results. Furthermore, to increase the numerical efficiency of the code, the NURBS are decomposed into Bézier curves. To evaluate the accuracy of the formulation, complex problems using high-order isogeometric boundary elements are analyzed. Their results are compared to analytical solutions showing good agreement.

Abstract BRS Rendeira and BRS Progresso are cassava (Manihot esculenta Crantz) cultivars with tolerance to post-harvest deterioration and high mean yields of fresh root (31.1 and 27.9 t ha-1) and starch (8.9 and 8.1 t ha-1) in annual production cycles. Both new varieties are recommended for the flour and starch industry.

ABSTRACT Tomato fruits are highly perishable. In this sense, adopting techniques to maintain and extend its shelf life is essential. Recent studies have used microalgae as an edible coating for fruit, as it is a nutrient-rich alternative and reduces fruit mass loss and respiration, delaying senescence. The aim of this study was to evaluate the application of microalgae-based coatings with or without the use of modified atmosphere packaging, polyvinyl chloride (PVC), in post-harvest tomato conservation. The design used was completely randomized, in a 4x2 factorial arrangement, with four coatings (no coating, coating composed of Spirulina platensis sp., Chlorella sp. and Scenedesmus sp.) and two conditions (with and without PVC), totalizing 8 treatments, with four replicates, consisting of one fruit each. Stored for 7 days at 10±2ºC and 55±5% UR and evaluated at harvest and on the last day of storage. The fruits coated with Chlorella sp. without PVC and Scenedesmus sp. associated with PVC, showed the lowest mass losses, representing a reduction of 73.79% and 78.47%, respectively, in relation to the control. In addition to mass loss, the levels of ascorbic acid (18.91 and 16.97 mg/100 g), citric acid (4.02 and 4.01), respectively, and the SS/AT ratio also stood out. The microalgae Chlorella sp. and Scenedesmus sp. can be used in coating ‘Santa Clara’ tomato fruits to maintain their physicochemical characteristics over 7 days of storage. The use of PVC film coating helped maintain these characteristics, reducing the perishability of the fruits.

RESUMO Os frutos do tomateiro têm alta perecibilidade havendo a necessidade da adoção de técnicas que mantenham e prolonguem sua vida útil pós-colheita. Estudos recentes têm utilizado microalgas como recobrimento comestível em frutos, por ser uma alternativa rica em nutrientes e reduzir perda de massa e respiração do fruto e assim retardar a senescência. Objetivou-se avaliar a aplicação de revestimentos a base de microalgas com ou sem o uso de embalagem com atmosfera modificada (policloreto de vinila) na conservação pós-colheita de tomate. O delineamento utilizado foi inteiramente casualizado, em arranjo fatorial 4x2, com quatro revestimentos (sem revestimento, revestimento com Spirulina platensis sp., Chlorella sp. e Scenedesmus sp.) e duas condições [com e sem PVC (policloreto de vinila)], totalizando 8 tratamentos, com quatro repetições, constituída por um fruto cada. Armazenados por 7 dias a 10±2ºC e 55±5% UR e avaliados na colheita e no último dia de armazenamento. Os frutos recobertos com Chlorella sp. sem o PVC e Scenedesmus sp. associado ao PVC, tiveram as menores perdas de massa, representando redução de 73,79% e 78,47%, respectivamente, em relação ao controle. Além da perda de massa, também tiveram destaque nos teores de ácido ascórbico (18,91 e 16,97 mg/100 g). As microalgas Chlorella sp. e Scenedesmus sp. podem ser utilizadas no revestimento de frutos do tomateiro ‘Santa Clara’ para manter suas características físico-químicas ao longo de 7 dias de armazenamento. A utilização do recobrimento com filme PVC auxilia na manutenção dessas características, diminuindo a taxa de perecibilidade dos frutos.

Resumo O processo de introdução de espécies exóticas é reconhecido como uma das maiores ameaças à ecologia e economia do planeta, devido às mudanças nas interações em comunidades biológicas nativas. Nesse sentido, relatar as bioinvasões é o primeiro passo para entender seu processo de implantação e criar estratégias para mitigar possíveis danos socioambientais. Aqui relatamos os primeiros registros de P. unifilis introduzidos no Pantanal Norte, Mato Grosso, Brasil. Obtivemos os primeiros registros das espécies ocasionalmente durante 2014 e 2015. Nos anos seguintes, de 2016 a 2019, realizamos observações sistemáticas por meio de incursões náuticas no rio Paraguai, entre a foz do rio Sepotuba e a Estação Ecológica Taiamã (TES). Incluímos também registros de terceiros, quando foi possível comprovar os locais de identificação e registro das espécies. Adultos de Podcnemis unifilis, filhotes e ninhos foram registrados em diferentes pontos ao longo do rio Paraguai. Nossos resultados indicam que P. unifilis foi introduzido próximo ao núcleo urbano de Cáceres há cerca de 30 anos. Atualmente, ela tem uma população estabelecida, registrando ninhos e filhotes por anos consecutivos. Uma em particular é a sua ocorrência no TES, importante viveiro natural de peixes e refúgio da fauna pantaneira. Assim, sugere-se o monitoramento contínuo de P.unifilis, uma vez que o ambiente do Pantanal com diversos ambientes aquáticos distintos, oferece condições favoráveis para o aumento da população da espécie no Pantanal Norte.

Abstract The process of exotic species introduction is recognized as one of the greatest threats to the ecology and economy of the planet, due to changes in interactions in native biological communities. In this sense, reporting bioinvasions is the first step to understanding its introduction process and creating strategies to mitigate possible socio-environmental damages. Here we report the first records of Podocnemis unifilis introduced in the Northern Pantanal, Mato Grosso, Brazil. We obtained the species’ first records occasionally during 2014 and 2015. In the following years from 2016 to 2019, we carried out systematic observations through nautical incursions on the Paraguay River, between the Sepotuba River mouth and the Taiamã Ecological Station (TES). We also included third part records, when it was possible to prove the species identification and registration sites. Podocnemis unifilis adults, hatchling and nests were recorded at different points along the Paraguay River. Our results indicate that P. unifilis was introduced close to the urban nucleus of Cáceres about 30 years ago. Currently, it has an established population, recording nests and hatchling for years in a row. A particular one is its occurrence at the TES, an important natural fish nursery and refuge for the wetland fauna. Thus, continuous monitoring is suggested from P.unifilis, since the Pantanal’s environment with several different aquatic environments, offers favorable conditions for the species population increase in the Northern Pantanal.

Abstract Tectonic rejuvenation has been widely described in ancient rifting areas of intraplate settings, despite extensive active tectonics being discontinued long ago. Various models have been invoked to justify such tectonic rejuvenation, suggesting that the long-term deformation in intraplate interiors may be more complex than once supposed. Inherited weakness zones, e.g., pre-existing faults are stress concentrators. However, not all weakness zones in plate interiors show tectonic rejuvenation and recognizing intraplate fault reactivation remains puzzling. Bedrock channels play an essential role in tectonically unstable landscapes and therefore they may unveil which pre-existing structures have been rejuvenated. Here we explore the Cinzas Catchment in order to investigate the interactions between tectonic rejuvenation, bedrock inheritance and geomorphic river signatures in an important Brazilian rifting feature, the Ponta Grossa Arch. We perform a geomorphic analysis combined with fieldwork, dating techniques and existing data to evaluate whether the geomorphic responses of the major rivers show perturbations related to the bedrock inheritance and post-rift rejuvenation. We also show that the interactions between river signatures and the bedrock fault zones are responses to post-rifting rejuvenation coupled with bedrock inheritance. This post-rifting rejuvenation is consistent with a mosaic of superimposed mechanisms which have been invoked by previous studies.

Abstract This study evaluated the effect of crude protein (CP) reduction in four diets (156, 139, 132, and 127 g Kg-1 DM) maintaining constant metabolizable protein (188 g/day) on the follicular fluid and cumulus-oocyte complexes of mid-lactating Girolando cows. Twenty-two Girolando cows with average of 21.55 ±3.19 L daily milk yield, 105.30 ±22.62 days in lactation and 3.22 ±0.03 body condition score were selected. To reduce CP in diets and maintain constant metabolizable protein, urea and soybean meal were gradually replaced by lignosulfonate-treated soybean meal (SoyPass®, Cargill), resulting in an increase in rumen-undegradable protein and a reduction in rumen degradable protein. A linear and quadratic reduction was observed in the plasma and follicular fluid urea nitrogen concentration following CP reduction, with the most intense reduction occurring in the 127 g Kg-1 DM group (p<0.001). As CP reduced, there was a tendency for a linear increase in the follicular growth rate (P=0.0696), on the number and proportion of viable oocytes (P<0.09), and also a linear increase for the number (P=0.0397) and proportion (P<0.09) of grade I viable oocytes. Plus, there was a linear effect for the number of cumulus oophorus cells. Cows fed with the lowest amount of CP had cumulus-oocyte complexes with higher numbers of cumulus oophorus cells (P=0.0238). Also, the reduction of diet crude protein was followed by a decrease in the probability of oocytes’ DNA degradation. In conclusion, the reduction of CP in the diet of mid-lactating Girolando cows, reduces urea nitrogen concentration in both blood plasma and follicular fluid, and, as a consequence, increases the viability of oocytes and the number of cumulus oophorus cells while reducing oocytes’ DNA degradation of follicular included cumulus-oocyte complex. The reduction on dietary CP may improve in vivo oocytes’ embryo development impacting fertility of lactating dairy cows.

Resumo A violência ocupacional é um agravo ao qual os profissionais de saúde estão cotidianamente expostos. O objetivo deste artigo é identificar a prevalência de violência no trabalho (verbal/física) e as variáveis relacionadas em profissionais de enfermagem atuantes em oncologia. Estudo transversal, em que a agressão física ou verbal foi avaliada por meio do autorrelato. Analisou-se a relação entre as variáveis sociodemográficas, psicoemocionais e relacionadas ao trabalho violência (verbal/física) por meio dos testes Qui-Quadrado, exato de Fisher, Test T Student e Mann-Whitney. A amostra do estudo foi composta por 231 profissionais de enfermagem. A prevalência de agressão física ou verbal referida no último ano foi de 61,5%. Maior prevalência de agressão foi evidenciada nos profissionais que afirmaram apresentar-se cansados ao final do plantão e com concentração diminuída durante este turno. Destaca-se que os trabalhadores que sofreram violência apresentaram Burnout em alto nível em todas as subescalas, maior escore médio na escala de estresse no trabalho e pior qualidade do sono. Os achados do presente estudo apontam para necessidade de medidas institucionais para prevenção e controle da violência ocupacional.

Abstract Occupational violence is a problem that health professionals are exposed to daily. This cross-sectional study aimed at identifying the prevalence of violence at work (verbal/physical) and the variables related to it in nursing professionals working in oncology. Physical or verbal aggression was assessed through self-report. The relationship between sociodemographic, psycho-emotional and work-related violence (verbal/physical) variables was analyzed using the Chi-Square, Fisher’s Exact, Student T and Mann-Whitney tests. The study sample consisted of 231 nursing professionals. The prevalence of physical or verbal aggression reported in the last year was 61.5%. A higher prevalence of aggression was evidenced in professionals who stated that they were tired at the end of the shift and presented reduced concentration during the shift. It is noteworthy that workers who suffered violence presented high levels of burnout in all subscales, a higher Mean score on the work stress scale and a lower Mean with regards to sleep quality. The findings of this study point to the need for institutional measures to prevent and control occupational violence.

Resumo Objetivou-se analisar a prevalência e os fatores associados à ideação suicida em travestis e transexuais. Estudo transversal, realizado entre 2015 e 2016 com travestis (n = 22) e transexuais (n = 36) associadas a quatro organizações civis do Rio Grande do Norte. Avaliou-se a diferença entre as categorias por meio dos testes qui-quadrado, exato de Fisher e de razão de verossimilhança. Realizou-se a análise múltipla por meio da regressão de Poisson com variância robusta. A prevalência de ideação suicida foi de 41,4% (IC 95%: 41,3-54,51%), sendo de 13,79% entre travestis (IC 95%: 4,91-22,66%) e 27,61% entre transexuais (IC 95%: 16,08-39,08%). Observou-se que apresentaram maior prevalência de ideação suicida os participantes com histórico de violência na escola (RP = 2,05; IC 95%: 1,08-3,87) e classificados com níveis depressivos moderado/grave (RP = 3,86; IC 95%: 1,51-9,83). Contexto escolar desfavorável e presença de sintomatologia depressiva parecem prejudicar a saúde mental e colaborar com a ideação suicida de pessoas transexuais e travestis.

Abstract The aim of this study was to determine the prevalence of suicidal ideation and explore associated factors among travestis and transsexuals. A cross-sectional study was conducted between 2015 and 2016 with 22 travestis and 36 transsexuals who were members of the four transgender organizations operating in the state of Rio Grande do Norte, Brazil. Associations between suicidal ideation and the categorical variables were measured using the chi-squared test, Fisher’s exact test, and likelihood ratios. Multivariate analysis was performed using robust Poisson regression. The suicidal ideation prevalence rate was 41.4% (95%CI 41.3-54.51%): 13.79% among travestis (95%CI 4.91-22.66%) and 27.61% in transsexuals (95%CI 16.08-39.08%). The prevalence of suicidal ideation was higher among respondents who reported suffering violence at school (PR = 2.05; 95%CI 1.08-3.87) and those experiencing moderate/severe depression (PR = 3.86; 95%CI 1.51-9.83). The findings suggest that unfavorable school contexts and the presence of depression compromise mental health and contribute to suicidal ideation among travestis and transsexuals.
