ABSTRACT To simplify the characterization of wood species, the Brazilian standard document ABNT NBR 7190-1 (2022) establishes the determination of mechanical properties employing the characteristic strength in the compression parallel to grain (fc0,k). This mechanical property is estimated using the linear relation given by the following expression fv0,k = 0.12·fc0,k Brazilian and European standard documents support the estimation of fv0,k using relations among properties. However, the European guidelines in the EN 384 (2019) have used the conventional characteristic strength in the static bending test (fM,k). Thus, this study aimed to investigate the efficiency of the ratio fv0,k = 0.12·fc0,k for adopting 30 hardwoods. The variance analysis results demonstrate the divergence among the experimental outcomes and those values estimated using the relation cited. Therefore, regression models at two parameters were considered to obtain more accurate estimates of fv0,k by adopting fc0,k, and fM,k as independent variables. Regarding the results, the geometric (R² = 80.80%) and linear (R² = 74.19%) models were the most accurate for the estimates of fv0,k in terms of fc0,k, and fM,k, respectively. This fact evinces the good accuracy of the models under consideration, which may provide a more rigorous structural design compared to the correlation currently prescribed by the ABNT NBR 7190-1 (2022).

RESUMO Para simplificar a caracterização de espécies de madeira, o documento normativo brasileiro ABNT NBR 7190-1 (2022) estabelece a determinação de propriedades mecânicas por meio da resistência característica na compressão paralela às fibras (fc0,k). Essa propriedade mecânica é estimada utilizando-se da relação linear dada pela expressão a seguir fv0,k = 0.12·fc0,k. Ambos os documentos normativos europeu e brasileiro prescrevem a estimativa da fv0,k empregando-se relações entre propriedades, embora as diretrizes da europeia contidas na EN 384 (2019) utilize a resistência característica convencional obtida no teste de flexão estática (fM,k). Assim, esse estudo teve o objetivo de investigar a eficiência da relação fv0,k = 0.12·fc0,k para 30 espécies folhosas. Os resultados da análise de variância demonstram a divergência entre os resultados experimentais e aqueles estimados utilizando-se da relação citada. Portanto, modelos de regressão em função de dois parâmetros foram considerados para se obter estimativas mais precisas da fv0,k através da adoção da fc0,k e fM,k como variáveis independentes. Com relação aos resultados, os modelos geométrico (R² = 80.80%) e linear (R² = 74.19%) foram os mais precisos para a estimativa da fv0,k em termos da fc0,k e fM,k, respectivamente. Este fato evidencia a boa precisão dos modelos em questão, o que pode proporcionar um dimensionamento estrutural mais rigoroso quando comparado à correlação atualmente prescrita pela ABNT NBR 7190-1 (2022).

Abstract The Brazilian Society of Angiology and Vascular Surgery has set up a committee to provide new evidence-based recommendations for patient care associated with chronic venous insufficiency. Topics were divided in five groups: 1. Classification, 2. Diagnosis, 3. Conservative or non-invasive treatment, 4. Invasive treatment and 5. Treatment of small vessels. This last series is closely related to the activities of Brazilian angiologists and vascular surgeons, who are heavily involved in the treatment of small superficial veins. These guidelines are intended to assist in clinical decision-making for attending physicians and health managers. The decision to follow a guideline recommendation should be made by the responsible physician on a case-by-case basis taking into account the patient's specific condition, as well as local resources, regulations, laws, and clinical practice recommendations.

Resumo A Sociedade Brasileira de Angiologia e de Cirurgia Vascular organizou uma comissão para fornecer novas recomendações baseadas em evidências sobre questões críticas de atendimento ao paciente com insuficiência venosa crônica. São abordados aqui os temas de classificação, diagnóstico, tratamento conservador, tratamento invasivo e tratamento de pequenos vasos. Esta última série está muito relacionada à atividade de angiologistas e cirurgiões vasculares, que possuem forte atuação no tratamento de pequenas veias superficiais. Estas diretrizes destinam-se a auxiliar na tomada de decisões clínicas de médicos assistentes e gestores de saúde. A decisão de seguir uma recomendação de diretriz deve ser feita pelo médico responsável caso a caso, levando em consideração a condição específica do paciente, bem como recursos locais, regulamentos, leis e recomendações de prática clínica.

Abstract Trauma is a leading cause of death, permanent disability, and health care cost worldwide. The young and economically active are the most affected population. Exsanguination due to noncompressible torso hemorrhage is one of the most frequent causes of early death, posing a significant challenge to trauma and vascular surgeons. The possibility of limb loss due to vascular injuries must also be considered. In recent decades, the approach to vascular injuries has been significantly modified. Angiotomography has become the standard method for diagnosis, endovascular techniques are currently incorporated in treatment, and damage control, such as temporary shunts, is now the preferred approach for the patients sustaining physiological derangement. Despite the importance of this topic, few papers in the Brazilian literature have offered guidelines on vascular trauma. The Brazilian Society of Angiology and Vascular Surgery has developed Projetos Diretrizes (Guideline Projects), which includes this publication on vascular trauma. Since treating trauma patients is a multidisciplinary effort, the Brazilian Trauma Society (SBAIT) was invited to participate in this project. Members of both societies reviewed the literature on vascular trauma management and together wrote these guidelines on vascular injuries of neck, thorax, abdomen, and extremities.

Resumo Trauma é uma causa importante de morbimortalidade, que acomete principalmente jovens. A hemorragia incoercível é o principal mecanismo de óbito precoce nessas vítimas, e as lesões vasculares não compressíveis representam grandes desafios para os cirurgiões. O traumatismo vascular impacta diretamente a viabilidade de membros traumatizados, aumentando o risco de amputação. Nas últimas décadas, muitas condutas de diagnóstico e tratamento de lesões vasculares traumáticas foram modificadas. A angiotomografia suplantou a angiografia como padrão ouro para diagnóstico, as técnicas endovasculares foram incorporadas ao arsenal terapêutico e o conceito de “controle de danos” foi estabelecido. No entanto, há lacunas na literatura nacional sobre a normatização de condutas em trauma vascular, principalmente considerando as limitações do Brasil. Por isso, a Sociedade Brasileira de Angiologia e de Cirurgia Vascular e a Sociedade Brasileira de Atendimento Integrado ao Traumatizado revisaram a literatura disponível sobre trauma vascular e organizaram diretrizes sobre o diagnóstico e tratamento dessas lesões.

Abstract The Brazilian Code ABNT NBR 7190 (1997) is currently under review process and one of the proposals is the change and add of some test procedures. Several specimen geometric configurations and test conditions have been evaluated by the study committee CE-02:126.10. The aim of this paper was the analysis of the tensile strength perpendicular to the grain through the current Brazilian Code and from an adaptation of ISO 13910 (2005). Pine and Indian Cedar were used and simplified relationships were proposed. Numerical simulations were performed to identify the stress distributions in the specimens. The results obtained by ISO 13910 (2005) did not differ statistically for the two species. Brazilian standard method cedar had a higher strength value than pine. The simplified ratios obtained ranged between 0,017 and 0,123. The numerical simulations of ISO 13910 (2005) specimens showed predominant failure by tension in the lower fiber due to stress concentration.

Resumo: O setor varejista de supermercados é de grande importância na geração de empregos e captação de mudanças no comportamento dos consumidores. Mudanças tecnológicas e mercadológicas ocorridas recentemente no setor aumentam a necessidade do aprimoramento de técnicas para a mensuração do desempenho individual das redes e a construção de parâmetros de comparação relativa entre as unidades. O objetivo deste artigo é analisar a eficiência de uma amostra de 31 supermercados de pequeno porte da região oeste de Santa Catarina. O método utilizado para a avaliação da eficiência foi a análise envoltória de dados (DEA), com as variáveis: faturamento, número de funcionários, área de vendas e o número de checkout’s, nos anos de 2014 e 2015. Os resultados encontrados apontaram para um baixo percentual de unidades em máxima eficiência de escala e técnica para os dois períodos analisados. Outra ponto relevante é a identificação das variáveis que apresentaram desajustes para o alcance da eficiência máxima das unidades (área de vendas e número de funcionários), sugerindo a existência de capacidade ociosa de estrutura.

Abstract: The retail supermarket sector is one of the most important in the third sector. Besides being one of that most generates direct and indirect jobs, it is one of the first to capture changes in consumer behavior. Given the strong competition and constant evolution of the sector, it is necessary to improve techniques for individual performance measurement of the networks and the construction of parameters of relative comparison between the units. The aim of this article is to analyze the efficiency of a 31 supermarkets sample in Santa Catarina, using Data Envelopment Analysis (DEA). The variables used in the investigation were gross sales, the number of employees, sales area and number of checkout's in the period of 2014 and 2015. The results pointed out a low percentage of units at maximum efficiency for the two periods analyzed. Another relevant finding was that the variables that presented a mismatch to reach the maximum efficiency of the units was the “Sales area (m2)” and “number of employees“, suggesting the existence of idle structure capacity.

RESUMO: Bovinos e equinos são os animais domésticos com maior incidência de raiva no Brasil. Este estudo avaliou formulários de solicitação de testes para raiva em herbívoros acompanhando amostras enviadas a um laboratório certificado de diagnóstico de raiva no estado do Rio Grande do Sul, Brasil. As informações foram obtidas sistematicamente de todos os formulários enviados ao laboratório em 2013 e 2014 utilizando um instrumento de coleta que selecionou variáveis sobre o tipo de formulário utilizado, município de origem, descrição do animal suspeito, sinais clínicos, coleta de amostra e procedimento de conservação. As 11 variáveis mais relevantes (município de origem, coordenadas geográficas, espécie, gênero, raça, idade, tamanho do rebanho, sinais clínicos, persistência de sinais clínicos, material biológico e conservação da amostra) foram avaliadas quanto à qualidade dos dados inseridos, e os dados percentuais foram calculados por formulário. No total, 603 formulários foram enviados para o laboratório. O formulário mais utilizado foi o FORM SN, (82,0%, 497/603). Dados classificados como “excelentes” e “bons” foram observados apenas para uma variável que descreve a localização de casos suspeitos de raiva ou surtos e animais (espécie, gênero, material biológico). A qualidade da entrada dos dados das variáveis que descrevem coordenadas geográficas, idade, raça, tamanho do rebanho, sinais clínicos, persistência de sinais e método de conservação da amostra variou entre “regular” e “ruim”. A qualidade dos dados dos formulários de solicitação de testes para herbívoros não foi devidamente fornecida em casos suspeitos de síndromes neurológicas, apontando para a necessidade de aumentar a conscientização e melhorar o treinamento do pessoal de campo.

ABSTRACT: Bovines and equines are the domestic animals with the highest incidence of rabies in Brazil. This study evaluated the data input in testing request forms for rabies in herbivores accompanying samples sent to a certified laboratory of rabies diagnosis in the state of Rio Grande do Sul, Brazil. Information was obtained systematically from all forms sent to the laboratory in 2013 and 2014 using a collection instrument that listed variables about the kind of form used, municipality of origin, description of the suspected animal, clinical signs, sample collection, and conservation procedure. The 11 most relevant variables (municipality of origin, geographic coordinates, species, gender, breed, age, herd size, clinical signs, persistence of clinical signs, biological material, and sample conservation) were assessed for the quality of the data entered, and percentage data input was calculated per form. In total, 603 forms were sent to the laboratory. The most used form was the FORM SN, (82.0%, 497/603). “Excellent” and “good” data inputs were observed only for one variable describing the location of suspected rabies cases or outbreaks and animals (species, gender, biological material). Quality of data input of variables describing geographic coordinates, age, breed, herd size, clinical signs, persistence of signs, and sample conservation method varied between “average” and “poor”. The data input in testing request forms for herbivores are not dully supplied in suspected cases neurological syndromes, pointing to the need to increase awareness and improve training of field staff.

ABSTRACT The objective with this study was to evaluate the impact of different swine nutritional strategies and technologies, as well as the land spread system, on logistical costs of pig manure distribution. For this, pigs were fed a conventional diet (C0) or a diet supplemented with 0.01% phytase (C1); organic minerals (40% substitution; C2); synthetic amino acids at reduced dietary crude protein levels (C3); or a combination of the three strategies (C4). All pig manure was weighed, then its chemical composition was determined. The mineral values and volume of manure produced were extrapolated to corresponding pig farm sizes in Sao Paulo state (300, 650, and 1000 sows) from real pig manure levels to produce simulations. To determine the logistical cost of manure distribution, two distribution systems were considered: vacuum tank tractor and vacuum tank truck (4.30 and 15 m3, respectively). The land spread truck system had the highest cost/hour worked due to the higher fuel consumption. However, this cost might be different over greater distances. Manure production, as well as the nutrient levels of N, P, and K, were lower for swine fed diets supplemented with nutritional technologies. Therefore, the different nutritional technologies reduced the transportation and distribution cost of pig manure by reducing the area and, consequently, the distances that need to be traveled for distribution. However, from an agronomic point of view (i.e., to meet a crop fertilization demand per hectare), manure from pigs fed diets supplemented with nutritional technologies had a higher application rate on land.

ABSTRACT This study aimed at establishing the morphological characteristics and morphometric indexes of Pêga donkeys, utilizing 47 animals, of which 22 were adults and 25 were growing donkeys. Prior to taking their measurements, the animals were restrained and made to stand squarely. The morphological data were measured, and the following morphometric indexes were determined: body index (BI), meloscopic index (MI), dactylothoracic index (DTI), weight in cannon index (WCI), conformation index (CFI), and real live weight (RLW). The experimental design was subdivided into plots and repeated in time, in which the animals represented the plot and the data collection times were the subplots. No sex effect was noted for the morphological measurements and morphometric indexes of growing donkeys. The effect of growth period was observed for all the variables. At birth, donkeys weighed around 14.86% of the weight of dams, and at six months they reached up to 40.37%. For the height taken at the withers, the animals at birth were 67.77% of the height of dams, and at six months they achieved up to 84.45%. Based on the morphometric indexes, it is suggested that adult and growing Pêga donkeys can be classified as being suited for both saddle and draft activities and possess a higher load capacity when compared with horses. A few indexes including BI, MI, and RLW need to be adjusted to be suitably used in rating the donkeys.

ABSTRACT Prolactinomas are the most common pituitary adenomas (approximately 40% of cases), and they represent an important cause of hypogonadism and infertility in both sexes. The magnitude of prolactin (PRL) elevation can be useful in determining the etiology of hyperprolactinemia. Indeed, PRL levels > 250 ng/mL are highly suggestive of the presence of a prolactinoma. In contrast, most patients with stalk dysfunction, drug-induced hyperprolactinemia or systemic diseases present with PRL levels < 100 ng/mL. However, exceptions to these rules are not rare. On the other hand, among patients with macroprolactinomas (MACs), artificially low PRL levels may result from the so-called “hook effect”. Patients harboring cystic MACs may also present with a mild PRL elevation. The screening for macroprolactin is mostly indicated for asymptomatic patients and those with apparent idiopathic hyperprolactinemia. Dopamine agonists (DAs) are the treatment of choice for prolactinomas, particularly cabergoline, which is more effective and better tolerated than bromocriptine. After 2 years of successful treatment, DA withdrawal should be considered in all cases of microprolactinomas and in selected cases of MACs. In this publication, the goal of the Neuroendocrinology Department of the Brazilian Society of Endocrinology and Metabolism (SBEM) is to provide a review of the diagnosis and treatment of hyperprolactinemia and prolactinomas, emphasizing controversial issues regarding these topics. This review is based on data published in the literature and the authors' experience.

RESUMO A madeira como material de construção sempre esteve presente no desenvolvimento da sociedade. É um material que se encontra praticamente em todas as etapas da obra e a construção civil é um dos setores que mais consome esse recurso. Em Mossoró-RN, a construção civil é um importante setor da economia emcrescimento, acarretando um intenso consumo de madeira. É possível evidenciar o crescimento urbano da cidade ao se passear pelos principais bairros em desenvolvimento, que são verdadeiros canteiros de obra. Esse trabalho teve como objetivo realizar uma avaliação sobre os principais usos da madeira na construção civil da cidade de Mossoró-RN, as principais espécies vegetais utilizadas e o destino final dos rejeitos gerados. As informações foram coletadas através de levantamento de dados junto com as empresas que comercializam a madeira e as empresas construtoras da cidade. Foi possível observar que a madeira é mais utilizada como item temporário nas obras do que como material permanente, quando a madeira é usada quase que exclusivamente como material de cobertura e esquadrias. O consumo de madeira na construção civil de Mossoró tem uma preferência pelo uso da espécie tropical Maçaranduba (Manilkara sp), proveniente do Pará, embora algumas madeireiras já comercializarem madeira proveniente de florestas plantadas em Minas Gerais e Paraná. Atualmente os resíduos de madeira da construção são coletados por empresas especializadas. Ainda não há uma consciência sobre o reaproveitamento ou reciclagem desse material dentro das construtoras no município.

ABSTRACT Wood as a building material has always been present in the development of society. It is a material that can practically be found during all stages of the construction and the construction industry is one of the sectors that has higher consumption of this feature. In Mossoro-RN, the construction industry is an important sector of the economy, causing an intense wood consumption. It is possible to see the urban growth of the city just walking through the main neighborhoods in development, which are real construction sites. This research aims to evaluate the main uses of wood by the civil construction of the city of Mossoro-RN, the main wood species used and the final destination that is given to the waste generated by its use. The information was collected through survey data with companies that sell wood and construction companies in the city. It was observed that the wood is used more as a temporary item than a permanent item in the construction, where it is applied almost exclusively as material for roofing and wood frames. The wood consumption for construction in Mossoró has a preference to the use of Maçaranduba wood (Manilkara sp), a tropical wood originating from the Pará state, however some wood shops had already start to negotiated wood from planted forests from Minas Gerais and Paraná states. Nowadays, the wood waste is collected by specialized companies. Still, there isn't an awareness about recycling and reuse of this kind of material, especially among the construction companies in Mossoró.

Abstract Introduction Skateboarding is one of the most popular cultures in Brazil, with more than 8.5 million skateboarders. Nowadays, the discipline of street skating has gained recognition among other more classical sports and awaits its debut at the Tokyo 2020 Summer Olympic Games. This study aimed to explore the state-of-the-art for inertial measurement unit (IMU) use in skateboarding trick detection, and to develop new classification methods using supervised machine learning and artificial neural networks (ANN). Methods State-of-the-art knowledge regarding motion detection in skateboarding was used to generate 543 artificial acceleration signals through signal modeling, corresponding to 181 flat ground tricks divided into five classes (NOLLIE, NSHOV, FLIP, SHOV, OLLIE). The classifier consisted of a multilayer feed-forward neural network created with three layers and a supervised learning algorithm (backpropagation). Results The use of ANNs trained specifically for each measured axis of acceleration resulted in error percentages inferior to 0.05%, with a computational efficiency that makes real-time application possible. Conclusion Machine learning can be a useful technique for classifying skateboarding flat ground tricks, assuming that the classifiers are properly constructed and trained, and the acceleration signals are preprocessed correctly.
