Abstract Sisal (Agave sisalana) is a plant exploited in semi-arid regions of Brazil for fiber production, but the floral scape of sisal (peduncle) is collected and often burned, causing environmental problems, even through irregular disposal. To circumvent this scenario, the objective of this work was to produce reconstituted panels using the sisal arrow and castor-based polyurethane resin. The panels were obtained using 175 g of crushed sisal arrow core with dimensions smaller than 2 mm and adopting 10% castor-based polyurethane resin and The samples were pressed under tension of 2 MPa. The properties of reconstituted panel were evaluated through NBR 14810-1 (ABNT, 2013) and NBR 14810-2 (ABNT, 2018), the physical properties were investigated: moisture, density, thickness swelling and absorption; as well as mechanical properties: MOR, MOE, internal bond and parallel compression. The found results show that the panel is classified as low density (419.8 kg/m³), and with physical and mechanical properties similars to other panels of the same classification in the literature. For average values of MOR and MOE it was found 5.24 MPa and 147.49 MPa, respectively. For internal bonding it was found 0.14 MPa and for parallel compression properties it was found 1.14 MPa.

Resumo O sisal (Agave sisalana) é uma planta explorada nas regiões semiáridas do Brasil para produção de fibras, mas o escapo floral do sisal (flecha) é coletado e frequentemente queimado causando problemas ambientais, até mesmo pelo descarte irregular. Para contornar este cenário, o objetivo deste trabalho foi produzir painéis reconstituídos usando a flecha do sisal e resina poliuretana à base de mamona. Os painéis foram obtidos empregando 175 g do miolo da flecha de sisal triturada com dimensões inferiores a 2 mm e adotando 10% de resina poliuretana à base de mamona e as amostras foram prensadas com tensão de 2 MPa. Avaliou-se no painel reconstituído, através da NBR 14810-1 (ABNT, 2013) e NBR 14810-2 (ABNT, 2018) as propriedades físicas: umidade, densidade, inchamento e absorção; bem como as propriedades mecânicas: MOR, MOE, força de ligação e compressão paralela. Os resultados encontrados mostram que o painel é classificado como de baixa densidade (419,8 kg/m³), e de propriedades físicas e mecânicas semelhantes a outros painéis de mesma classificação da literatura. Para MOR e MOE foram encontrados 5,24 MPa e 147,49 MPa de média, respectivamente. Já os ensaios de tração perpendicular e compressão paralela obtiveram resultados de 0,14 MPa e 1,14 MPa, respectivamente.

Resumo Introdução: Existem redes de cooperação internacional compostas por instituições de segurança pública para promoção, prevenção e repressão de crimes transnacionais organizados, as quais precisam de alguns fatores para que funcionem adequadamente. Objetivo: Analisar a percepção de confiabilidade dos adidos da Polícia Federal no compartilhamento de informações com os atores das instituições congêneres internacionais, em apoio às investigações de crimes. Métodos: A pesquisa é caracterizada como descritiva, transversal com abordagem qualitativa. Por amostragem censitária, foram realizadas entrevistas virtuais com adidos da Polícia Federal de 16 países, com apoio de roteiro semiestruturado. Os dados foram transcritos e submetidos à análise de conteúdo, sendo que algumas categorias foram estabelecidas a priori e outras a posteriori. Resultados: A percepção de confiabilidade da contraparte só é realizada quando a informação é classificada como sensível, e é suprimida quando a instituição tem boa reputação. Percebeu-se extrema relevância da presença física do adido, principalmente nas interações com atores confiáveis de instituições cuja reputação é negativa. Constatou-se a variação nos critérios de análise da percepção de confiabilidade adotadas pelos adidos referentes a competência, integridade e benevolência, sendo que a integridade foi o critério priorizado pela moda. Conclusões: A percepção de confiabilidade dos adidos influencia as investigações de crimes, pelo incremento da disposição para compartilhar informações da contraparte e fomento a disponibilidade e qualidade destas. A abordagem qualitativa contribuiu para o aprofundamento da análise de percepção sobre a relação de confiabildiade e compartilhamento de informações, pois permitiu detalhamento e exemplificação de casos que subsidiaram a criação de categorias temáticas.

Abstract Introduction: There are international cooperation networks composed of public security institutions for the promotion, prevention and repression of transnational organized crimes, which need some factors to function properly. Goals: To analyze the perception of reliability of Federal Police attaches in sharing information with actors from similar international institutions, in support of crime investigations. Methods: The research is characterized as descriptive, transversal with a qualitative approach. By census sampling, virtual interviews were conducted with Federal Police attachés from 16 countries, with the support of a semi-structured script. Data were transcribed and submitted to content analysis, with some categories established a priori and others a posteriori. Results: The counterparty's reliability perception is only realized when the information is classified as sensitive, and is suppressed when the institution has a good reputation. The attache's physical presence was extremely important, especially in interactions with reliable actors from institutions whose reputation is negative. There was a variation in the analysis criteria for the perception of reliability adopted by the attachés referring to competence, integrity and benevolence, integrity being the criterion prioritized by the mode. Conclusions: The attachés' perception of reliability influences the investigation of crimes, by increasing the willingness to share counterpart information and promoting its availability and quality. The qualitative approach contributed to the deepening of the perception analysis on the relationship of reliability and information sharing, as it allowed detailing and examples of cases that supported the creation of thematic categories.

ABSTRACT Combining refrigeration with packaging is a commonly used technique for fruits intended for export. Thus, the objective of this study was to adapt the post-harvest management of biofortified sweet potato cultivars, using packaging and refrigeration, focused on reaching distant export markets while maintaining the commercial quality. Sweet potatoes of the cultivars BRS-Amélia and Beauregard were selected after harvesting, washed, and packaged. The experimental design used was completely randomized, in a 4 × 7 factorial arrangement consisted of 4 treatments (cultivar BRS-Amélia with and without packaging; and cultivar Beauregard with and without packaging) and 7 evaluations under storage conditions: at 0, 7, 14 (under refrigeration at approximately 8 °C), 17, 20, 23, and 26 days (under room temperature conditions at approximately 25 °C). Each experimental unit contained 500 g of tubbers. The results showed that the refrigerated storage combined with packaging extended the shelf life of the evaluated sweet potatoes: 17 days for BRS-Amélia and 26 days for the cultivar Beauregard. The BRS-Amélia cultivar maintained higher firmness, soluble solids and carbohydrate contents, chroma, and antioxidant activity (FRAP method), and total phenolic contents, in both raw and cooked tissues. The cultivar Beauregard presented less dehydration and greater stability in vitamin C, total phenolic, total carotenoid, soluble carbohydrate, and starch contents in raw and cooked potatoes. Therefore, the combination of packaging and refrigeration preserved the commercial quality of biofortified sweet potatoes for export markets.

RESUMO Combinar refrigeração com embalagem é uma técnica comumente utilizada para frutas destinadas à exportação. Assim, o objetivo deste estudo foi adequar o manejo pós-colheita de cultivares de batata-doce biofortificadas, utilizando embalagem e refrigeração, com foco em atingir mercados de exportação distantes e mantendo a qualidade comercial. As batatas-doces das cultivares BRS-Amélia e Beauregard foram selecionadas após a colheita, lavadas e embaladas. O delineamento experimental utilizado foi inteiramente casualizado, em arranjo fatorial 4 × 7 composto por 4 tratamentos (cultivar BRS-Amélia com e sem embalagem; e cultivar Beauregard com e sem embalagem) e 7 avaliações nas condições de armazenamento: aos 0, 7, 14 (sob refrigeração a aproximadamente 8 °C), 17, 20, 23 e 26 dias (sob condições de temperatura ambiente a aproximadamente 25 °C). Cada unidade experimental continha 500 g de tubérculos. Os resultados mostraram que o armazenamento refrigerado aliado à embalagem prolongou a vida útil da batata-doce avaliada: 17 dias para BRS-Amélia e 26 dias para a cultivar Beauregard. A cultivar BRS-Amélia manteve maior firmeza, solúveis sólidos e teor de carboidratos, croma e atividade antioxidante (método FRAP) e teor de fenólicos totais, tanto nos tecidos crus quanto cozidos. A cultivar Beauregard apresentou menor desidratação e maior estabilidade nos teores de vitamina C, fenólicos totais, carotenóides totais, carboidratos solúveis e amido em batatas cruas e cozidas. Portanto, a combinação de embalagem e refrigeração preservou a qualidade comercial da batata-doce biofortificada para os mercados de exportação.

Abstract Background: Real-world, primary data on the treatment of psoriasis are scarce, especially concerning the role of soluble biomarkers as outcome predictors. Objective: The authors evaluated the utility of Th1/Th17 serum cytokines along with clinical characteristics as predictors of drug survival in the treatment of psoriasis. Methods: The authors consecutively included participants with moderate to severe psoriasis who were followed up for 6 years. Baseline interferon-α, tumor necrosis factor-α, and inter-leukin (IL)-2, IL-4, IL-6, IL-10, and IL-17A were measured using a cytometric bead array; clinical data were assessed. The authors calculated hazard ratios (HRs) for drug survival using a Cox proportional hazards model. Results: The authors included 262 patients, most of whom used systemic immunosuppressants or biologics. In the multivariate model, poor quality of life measured by the Dermatology Life Quality Index (HR = 1.04; 95% CI 1.01–1.07; p = 0.012) and elevated baseline IL-6 (HR = 1.99; 95% CI 1.29–3.08; p = 0.002) were associated with treatment interruption. Study limitations: The main limitation of any cohort study is the presence of confounders that could not be detected in clinical evaluation. Conclusions: Poor quality of life and elevated baseline serum IL-6 level predicted treatment interruption in patients with moderate to severe psoriasis. Although IL-6 is not the most important mediator of the inflammatory pathway in the skin environment, it is an interesting biomarker candidate for predicting psoriasis treatment response.

Resumo Mancha-de-Bipolaris é uma das mais importantes doenças foliares do milho. Estratégias de manejo adequadas e o uso de cultivar resistente permitem o controle da doença, mas para tanto, conhecer os aspectos associados ao patógeno e a resposta do hospedeiro é necessário para traçar estratégias eficientes para seleção de genótipos resistentes a essa doença. Neste sentido, objetivou-se realizar a caracterização do isolado de Bipolaris maydis avaliando a patogenicidade em diferentes linhagens de milho-pipoca e os sintomas gerados no hospedeiro a partir da inoculação. A caracterização do isolado consistiu na avaliação macromorfológica das colônias e micromofológica dos conídios em meio nutritivo BDA. Para avaliação da patogenicidade do isolado foi conduzido um experimento em casa de vegetação utilizando 20 linhagens endogâmicas de milho-pipoca, com delineamento em blocos casualizados, com quatro repetições. A inoculação foi realizada por meio de pulverização em folhas, com uma suspensão contendo 1,0 x 104 conídios.ml-1 do isolado CF/UENF 501 de B. maydis. Foi realizada uma avaliação de incidência e três avaliações de severidade dos sintomas da doença, com o intervalo de sete dias para cada avaliação. Os dados da caracterização morfológica do isolado foram analisados por meio da estatística descritiva e para severidade da doença foi aplicado o modelo de regressão linear de primeiro grau. Realizou-se a análise de variância para o coeficiente linear e angular obtido para cada tratamento e quando constatada diferença aplicou-se o agrupamento de médias de Scott-knott a 5% de significância. O isolado apresentou colônias com coloração cinza esverdeado, aspecto algodonoso e forma irregular. As linhagens L353 e L354 e L624 estão entre as linhagens que apresentaram maior resistência no inicio e ao longo das avaliações. A elevada virulência do isolado CF/UENF 501 possibilitou diferenciar as linhagens quanto a intensidade da doença, bem como o padrão dos sintomas apresentados.

Abstract Southern corn leaf blight (SCLB) is one of the most important corn leaf diseases. Appropriate management strategies and the use of resistant cultivars allow disease control. Therefore, knowing the aspects related to the pathogen and the response of hosts makes it possible to design efficient strategies for selecting genotypes resistant to this disease. In this sense, the objective was to carry out the Bipolaris maydis isolate characterization, evaluating the pathogenicity in different popcorn lines and the symptoms generated in the host after inoculation. The isolate characterization consisted of the macromorphological evaluation of the colonies and the micromorphological evaluation of the conidia in the PDA medium. An experiment was carried out in a greenhouse to evaluate the pathogenicity of the isolate, using 20 inbred lines of popcorn in a randomized block design with four replicates. Inoculation was carried out by spraying leaves, with a suspension containing 1.0 x 104 conidia.ml-1 of the CF/UENF 501 isolate of B. maydis. An incidence assessment and three assessments of disease symptom severity were performed, with seven days intervals between evaluations. The morphological characterization data of the isolate were analyzed using descriptive statistics, and for disease severity, the linear regression model was applied the first-degree model. The variance analysis was performed for the linear and angular coefficients obtained for each treatment. When a difference was found, the Scott-Knott clustering algorithm at 5% significance was applied. The isolate had gray-green colonies, a cottony appearance, and an irregular shape. The lines L353, L354, and L624 show more resistance at the beginning and throughout the evaluations. The high virulence of the CF/UENF 501 isolate made it possible to differentiate the lines in terms of disease intensity and the pattern of symptoms presented.

Resumo O setor florestal brasileiro se destaca pela tecnologia, práticas de manejo florestal, responsabilidade social e ambiental e, principalmente, alta produtividade, mas pragas exóticas podem reduzir isto. O parasitoide Psyllaephagus bliteus (Riek, 1962) (Hymenoptera: Encyrtidae), percevejos predadores e fungos entomopatogênicos como Beauveria bassiana e Metarhizium anisopliae são inimigos naturais usados no controle biológico do psilídeo-de-concha do eucalipto Glycaspis brimblecombei (Moore, 1964) (Hemiptera: Aphalaridae), praga em plantios de eucalipto. A utilização de fungos entomopatogênicos contra pragas exóticas vem aumentando no setor florestal e a prospecção e identificação de isolados fúngicos é importante para o manejo integrado de pragas. O objetivo deste estudo foi o isolamento e identificação molecular de Cordyceps spp. e avaliar a patogenicidade dos isolados de Cordyceps javanica (LCBPF 11) e Cordyceps fumosorosea (LCBPF 12 e LCBPF 63), obtidos de adultos de Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae), ao psilídeo-de-concha G. brimblecombei. Os fungos foram isolados de adultos de B. tabaci encontrados em culturas de soja e tomate e identificados molecularmente. Os conídios foram suspensos em solução com Tween 80 (0,1%) na concentração de 1,0 x 108 conídios/mL e pulverizados sobre dez ninfas de G. brimblecombei por folha de Eucalyptus cortada e colocada sobre gel hidrorretentor no interior de placas de Petri por repetição. O número de insetos mortos foi quantificado, diariamente, por sete dias e transferidos para câmaras úmidas. Cordyceps javanica (LCBPF 11) e C. fumosorosea (LCBPF 12 e LCBPF 63) foram identificados por análise molecular e todos os isolados foram patogênicos para os insetos. Isto indica serem importantes para o manejo de G. brimblecombei e confirma relatos de que, normalmente, fungos causam maiores mortalidades em insetos da mesma ordem daquela da qual foram isolados.

Abstract The Brazilian forestry sector stands out for its technology, forestry management practices, social and environmental responsibility and, mainly, for its high productivity and exotic pests can reduce it. The red gum lerp psyllid Glycaspis brimblecombei (Moore, 1964) (Hemiptera: Aphalaridae) is an important pest in Eucalyptus plantations. The parasitoid Psyllaephagus bliteus (Riek, 1962) (Hymenoptera: Encyrtidae), predatory bugs and entomopathogenic fungi such as Beauveria bassiana and Metarhizium anisopliae are the natural enemies and used in the biological control of the red gum lerp psyllid. The use of entomopathogenic fungi against exotic pests is increasing in the forestry sector and the prospecting and identification of fungus isolates is important for integrated pest management. The objective of this work was the isolation and molecular identification of Cordyceps spp. And to evaluate the pathogenicity of isolates, obtained from Bemisia tabaci (Gennadius, 1889) (Hemiptera: Aleyrodidae) adults, against to the red gum lerp psyllid G. brimblecombei. The fungi were isolated from B. tabaci adults found in soybean and tomato crops and molecularly identified. The conidia obtained were suspended in solution with Tween 80 (0.1%) at a concentration of 1.0 × 108 conidia/mL and sprayed on ten G. brimblecombei nymphs per Eucalyptus leaf cut and placed on a hydroretentive gel inside per Petri dishes as a replication. The number of dead insects was quantified, daily, for seven days, and transferred to humid chambers. Cordyceps javanica (LCBPF 11) and C. fumosorosea (LCBPF 12 and LCBPF 63) were identified with a molecular analysis and all isolates were pathogenic to the insects and indicates that they could be used to manage G. brimblecombei and adds to reports that, normally, fungi cause greater mortality on insects of the same order as that from which they were isolated.

Resumo Os sabonetes têm um papel importante para a nossa higiene e saúde, pois eles além de ter efeito bactericida, também removem as sujeiras presentes no corpo humano. Avaliar a eficácia de sabonetes com atividade antimicrobiana de diferentes marcas comerciais vendidas no Brasil. Foram realizados ensaios da atividade antimicrobiana dos diferentes sabonetes através do método difusão em ágar frente aos microrganismos Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Enterobacter cloacae, Acinetobacter baumannii, Proteus mirabilis e Candida albicans. Todos os sabonetes comerciais testados apresentaram formação de halo de inibição antimicrobiana frente às bactérias S. aureus e P. aeruginosa. Apenas dois sabonetes comerciais apresentaram inibição das espécies A. baumannii e C. albicans. Nenhum dos sete produtos estudados apresentou inibição das bactérias E. cloacae, P. mirabilis e E. coli. Na comparação das informações contidas nas embalagens dos produtos com os resultados obtidos durante a pesquisa realizada foram observadas divergências. Os sabonetes que apresentaram maior eficiência contra os microrganismos testados foram aqueles das apresentações 1 e 2, que se mostraram eficazes contra as espécies de bactérias S. aureus, P. aeruginosa e A. baumannii e contra a espécie de fungo C. albicans. As marcas 3, 4, 5, 6 e 7 apresentaram o mesmo resultado de sensibilidade frente as bactérias das espécies S. aureus e P. aeruginosa, com variação quantitativa apenas do halo de inibição. Houve divergência entre as informações contidas nas embalagens dos sete produtos em estudo e os resultados dos testes experimentais.

Abstract Soaps play an important role in our hygiene and health, as they not only have a bactericidal effect but also remove dirt from the human body. To evaluate the effectiveness of soaps with antimicrobial activity from different commercial brands sold in Brazil. Tests of the antimicrobial activity of different soaps were carried out through diffusion in agar against the microorganisms Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Enterobacter cloacae, Acinetobacter baumannii, Proteus mirabilis, and Candida albicans. All commercial soaps tested transfer antimicrobial inhibition halo formation against S. aureus and P. aeruginosa bacteria. Only two commercial soaps inhibit the species A. baumannii and C. albicans. None of the seven products studied showed inhibition of E. cloacae, P. mirabilis, and E. coli bacteria. When comparing the information contained in the packaging of the products with the results obtained during a survey, divergences were observed. The soaps that provide greater efficiency against the tested microorganisms were presented in presentations 1 and 2, which become useful against the bacteria species S. aureus, P. aeruginosa, and A. baumannii and a fungus species C. albicans. Marks 3, 4, 5, 6, and 7 parallel the same sensitivity result opposite as bacteria of the species S. aureus and P. aeruginosa, with quantitative variation only of the inhibition halo. There was a divergence between the information contained in the packaging of the seven products under study and the results of the experimental tests.

Abstract Analytical and computational calibrations and subsequent parametric analyses were performed on the four UHPFRC beams under flexure to estimate their actual shear strength. The computational models were calibrated using different values for the CDP parameters, and a finite element mesh sensitivity study was conducted. These models predicted the experimental behavior satisfactorily, and the analytical model was also able to find the beams’ failure loads and proved to be a simple tool to estimate their behavior. The parametric analysis showed that the current beams did not require stirrups once the UHPFRC had high shear strength, and the maximum shear capacity was accurately determined.

Abstract Vegetative propagation methods of acerola cherry are important in standardizing orchards and fruit quality, and the cutting process has been investigated as a promising alternative. The present work aimed to propose the best combination of substrate and cutting type (herbaceous and semi-woody) to provide a greater root rate and seedling development. The trial was conducted in a greenhouse at the State University of Maranhão, in São Luís - MA under intermittent nebulization conditions. The cuttings with dimensions of 10 cm were treated with indole butyric acid (IBA) at a concentration of 2,000 mg L-1, and as substrate were used vermiculite (MV), Plantmax ® (PL) (commercial substrate based on decomposed pine bark), agricultural soil + tanned and sieved bovine manure (S + M) (50% + 50%, v / v); and vegetable soil (VS) composed of fresh soil with the remains of decomposed plants (leaves, stems, bark, and tree fern). The experiment was laid out in a randomized complete design in a 2 x 4 factorial arrangement (2 types of cuttings x 4 substrates) with eight replications with five cuttings per plot. At 60 days after the establishment of the trial, it was concluded that the best combination for rooting cuttings was vermiculite with herbaceous cuttings because they favor a higher rooting rate (95.0%). The alternative substrate composed of soil and tanned bovine manure provided promising results in the rate of rooting (72.5%), root formation, and vegetative development of the aerial part.

Abstract The use of computational simulation techniques is an important tool for the coffee harvesting issues, particularly the finite element method. The method is widely used in the structural analysis of agricultural machinery, as well as in the analysis of the stresses and vibrations of coffee branches and peduncles during the harvesting process. The present study aimed to develop three-dimensional finite element models of the plagiotropic branches of the Catuaí Vermelho variety of Arabica coffee in different positions along the orthotropic branches of the plant; considering high-fidelity models. Additionally, by considering the branches’ experimental properties (physical-mechanical), the natural frequencies and vibration modes of the branches were determined by means of computer simulations. First, the geometric properties of the coffee branches were obtained by means of two images taken using a professional camera to obtain the input data of the virtual simulation. For the mechanical properties, it was used a semi-analytical digital scale, to obtain the mass of the specimens. The modulus of elasticity was determined using a universal testing machine. The variability in the simulated natural frequencies could be identified, which was on the order of 30% for the first frequency, regardless of the position of the branch in the plant. These values were lower for the other frequencies. Linear regression fits showed a coefficient of determination, and correlation tests were used to verify the relationship between the values obtained numerically and experimentally, which were validated by using experimental data using the modal analysis techniques.

Abstract With the growing demand for solutions to prevent and resolve faults in gas-insulated substations that affect the operation of the electrical system, a fault simulation laboratory for gas-insulated substations was developed to develop solutions for monitoring and locating these faults. The laboratory is composed of instruments for a fault location system based on traveling wave theory. The laboratory also has computational programs for fault simulation control and signal acquisition, in addition to having tools to analyze the data. The results were obtained through tests carried out that confirmed the laboratory's ability to simulate the operation of faults in gas-insulated substations, which allowed demonstrating the capacity of the fault location system using the theory of traveling waves.

ABSTRACT Calcium (Ca) is a nutrient responsible for maintaining plant quality and fruit yield. The production of new Ca sources, such as micronized (CaM) and complexed Ca (CaC), and their supplementation provide a better yield in mango cultivation. This study aimed to evaluate the efect of Ca sources (micronized and complexed with Ascophyllum nodosum) and application methods on mango cultivation, in semi-arid Brazil. The experimental design was randomized blocks, in a 6 × 6 factorial scheme. The Ca supplementation strategies (control; 1 L ha−1 of CaM; 2 L ha−1 of CaM; 2 L ha−1 of CaC with A. nodosum extract; 2 L ha−1 of CaC with A. nodosum extract + application of 2.5 L ha−1 via CaC fertigation; and 2.5 L ha−1 via CaC fertigation) were evaluated on six dates regarding nutritional aspects. For biochemical and production aspects, the six supplementation strategies with Ca were evaluated. The Ca concentration in leaves and fruits signifcantly afected the interaction among the factors. The fertilization strategy with 2.5 L ha−1 of complexed calcium via fertigation was fundamental to provide increases in the nitrogen and Ca concentration of the fruits from 65 days after full fowering, and had positive efects on fruiting and production of mangoes cv. Kent.

RESUMO O cálcio (Ca) é um nutriente responsável por manter a qualidade de plantas e o rendimento de frutas. A produção de novas fontes de Ca, como o Ca micronizado (CaM) e o Ca complexado (CaC), e sua suplementação proporcionam um melhor rendimento no cultivo de mangueiras. Avaliou-se o efeito de fontes de Ca (micronizado e complexado com Ascophyllum nodosum) e métodos de aplicação no cultivo de mangueiras, no semiárido brasileiro. O delineamento experimental foi em blocos ao acaso, em esquema fato rial 6 x 6. As estratégias de suplementação de Ca (controle; 1 L ha−1 de CaM; 2 L ha−1 de CaM; 2 L ha−1 de CaC com extrato de A. nodosum; 2 L ha−1 de CaC com extrato de A. nodosum + aplicação de 2,5 L ha−1 via fertirrigação de CaC; e 2,5 L ha−1 via fertirrigação de CaC) foram avaliadas em seis datas, quanto aos aspectos nutricionais. Para aspectos bioquímicos e de produção, as seis estratégias de suplementação com Ca foram avaliadas. A concentração de Ca nas folhas e frutos afetou signifcativamente a interação entre os fatores. A estratégia de fertilização com 2,5 L ha−1 de cálcio complexado via fertirrigação foi fundamental para proporcionar aumentos na concentração de nitrogênio e Ca nos frutos a partir de 65 dias após a foração completa e teve efeitos positivos na frutifcação e produção de mangas cv.

Abstract Roadkill is one of the most direct impacts on fauna, leading to numerous direct and indirect impacts. Road-killed animals could serve as a resource for research and teaching purposes, but first, they need to have their tissues preserved by some technique. Plastination is one of the most modern techniques for the conservation of biological tissues, its principle is the replacement of body fluids by a curable polymer, resulting in a non-toxic, odorless, and manipulable material. So the main aim of this work was to compose a collection of plastinated roadkill victims from the Biological Reserve Sooretama region, adapting the standard protocol to the different taxa worked here (Avialae, Reptilia, Amphibia, and Mammalia). For this, 42 animals were used, previously frozen and stored in the Sooretama Biological Reserve and Vale Natural Reserve until they were sent for processing. Upon arriving at the Plastination laboratory at the Federal University of Espírito Santo, the animals underwent the 4 stages of plastination: fixation, dehydration, forced impregnation, and chemical cure; some adaptations were made to improve the final specimens. The results proved that the plastination of these animals is extremely viable in generating satisfactory results. Given the results obtained, it becomes clear how plastination can become an alternative to implement in the composition of biological collections using roadkill animals. The animals prepared in this work comprise an unprecedented collection available for different applications, such as exhibitions, practical classes, and research.

ABSTRACT BACKGROUND: Considering the ability of the health and self-management in diabetes questionnaire (HASMID-10) to verify the impact of self-management on diabetes, we highlight its relevance to scientific research and clinical applicability. However, to date, no study has been conducted to scientifically support its use in other languages. OBJECTIVE: To translate, cross-culturally adapt, and validate the HASMID-10 into the Brazilian Portuguese. DESIGN AND SETTING: A translation, cross-cultural adaptation, and validation study conducted at Ceuma University. METHODS: Study was conducted in accordance with the Guidelines for the Process of Cross-Cultural Adaptation of Self-Report Measures and Consensus-based Standards for the Selection of Health Measurement Instruments. We included participants of both sexes diagnosed with diabetes, aged between 18 and 64 years, and without cognitive deficits or any other limitations that would prevent them from answering the questionnaire. We assessed participants using the problem areas in diabetes (PAID) scale and HASMID-10. We assessed reliability using a test-retest model with a 7-day interval between assessments. We used intraclass correlation coefficient (ICC), 95% confidence interval (CI), standard error of measurement (SEM), minimum detectable difference (MDD), Spearman correlation coefficient, and floor and ceiling effects. RESULTS: Sample comprised 116 participants, most of whom were women, overweight, non-practitioners of physical activity, and nonsmokers. We observed significant correlations (P = 0.006; rho = −0.256) between the HASMID-10 and PAID, adequate reliability (ICC = 0.780) and internal consistency (Cronbach's alpha = 0.796). No ceiling or floor effects were observed. CONCLUSION: HASMID-10 has adequate measurement properties and may be used for Brazilians.
