Aprendizado espaço-tempo no forrageamento de abelhas sem ferrão amazônicas (Apidae, Meliponini)

Os meliponídeos são um táxon chave para a manutenção da biodiversidade por realizarem a polinização de diversas espécies. O padrão de coleta de recursos naturais é amplamente estudado e esta relacionado com a polinização, pois influencia tanto a coleta de recursos pelas abelhas quanto na fecundação cruzada das plantas. Néctar e pólen são recursos altamente disputados, tanto por outras espécies de meliponídeos quanto por outros animais. Dessa maneira, aprender a localização de um recurso, e a hora do dia que tal recurso é oferecido, é uma vantagem adaptativa importante. Nesse trabalho foi estudado se duas espécies de abelhas sem ferrão, Melipona fasciculata e Scaptotrigona postica, apresentam atividade alimentar antecipatória (AAA) como mecanismo importante para maximização da exploração de um recurso renovável. Em ambas ocorreu o fenômeno da antecipação, que deve ter evoluído para minimizar a competição com outras colônias, embora a precisão dessa antecipação varie entre as duas espécies.

Nutritional potential of green banana flour obtained by drying in spouted be

Este estudo avaliou a composição química da farinha de banana verde sem casca e com casca, obtido por secagem em leito de jorro, com o objetivo de agregar valor nutricional a produtos alimentícios. As bananas foram cortadas e trituradas para a obtenção de uma pasta, sendo esta alimentada no secador leito de jorro (12 cm de altura e T = 80 º C), a fim de obter uma farinha. As farinhas obtidas foram submetidas a análise da umidade, proteína, cinzas, Carboidratos totais, amido total, amido resistente, e fibras. As farinhas de banana verde, principalmente com casca, são boas fontes de fibras e amido resistente, com uma média de 21,91g/100g e 68,02g/100g respectivamente. O teor médio de proteína encontrado foi para 4,76g/100g, sendo classificada como uma proteína de baixo valor biológico, tendo a lisina como o primeiro aminoácido limitante. Os resultados mostraram que a farinha de banana verde com casca obtida por secagem em leito de jorro pode ser uma ferramenta valiosa para agregação de valor nutricional aos produtos, a fim de aumentar a sua fracção não digerível.

Enhanced Recovery after Elective Open Surgical Repair of Abdominal Aortic Aneurysm: A Complementary Overview through a Pooled Analysis of Proportions from Case Series Studies

Objectives: To evaluate the efficacy and safety of enhanced recovery after surgery (ERAS) programs in elective open surgical repair (OSR) of abdominal aortic aneurysm (AAA).Background: Open surgical repair of AAA is associated with high morbidity and mortality, prolonged hospital stay and high costs. ERAS programs contribute to the optimization of treatment by reducing hospital stay and improving clinical outcomes.Methods: A review of PubMed, EMBASE and LILACS databases was conducted. As only one randomized controlled trial was found, a pooled analysis of proportions from case series was conducted, considering it a complementary overview of the topic. Inclusion criteria were case series with more than five cases reported, adult patients who underwent an elective OSR of AAA and use of an ERAS program. ERAS was compared to conventional perioperative care. The pooled proportion and the confidence interval (CI) are shown for each outcome. The overlap of the CI suggests similar effect of the interventions studied.Results: Thirteen case series studies with ERAS involving 1,250 patients were compared to six case series with conventional care with a total of 1,429 patients. The pooled, respective proportions for ERAS and conventional care were: mortality, 1.51% [95% CI: 0.0091, 0.0226] and 3.0% [95% CI 0.0183, 0.0445]; and incidence of complications, 3.82% [95% CI 0.0259, 0.0528] and 4.0% [95% CI 0.03, 0.05].Conclusion: This review shows that ERAS and conventional care therapies have similar mortality and complication rates in OSR of AAA.

Distribuição natural de espécies arbóreas em áreas com diferentes níveis de antropização e relação com os atributos químicos do solo

With the emergence of areas degraded by human activities, the chemical soil properties and silvicultural characters became important in understanding the succession process of tree species and planning of landscape restoration. This study aimed to evaluate the distribution of tree species in areas with different levels of human disturbance, relating silvicultural aspects to the soil chemical properties and characterizing the type of vegetation, for integration of genetic conservation program in situ. The study was conducted in the area of Research and Extension Experimental Farm (FEPE) from UNESP, Ilha Solteira, in Selviria - MS. Through transect, 64 plots were marked 50 m equidistant with dimensions of 10 x 10 m, where: 29 plots were in an highly disturbed area (HDA), five in moderately disturbed area (MDA), 15 in lowly disturbed area (LDA), six in riparian stream of Vestia river (Riparian Forest) and nine in the legal reserve. Soil samples were collected at two depths (0.0 to 0.20 and 0.20 to 0.40 m) for the chemical analysis and the assessment of silvicultural characters, such as height, diameter at breast height (DBH) and shape. The study of the natural distribution of tree species and edaphic condition in the different evaluated areas showed that: the soil chemical properties associated with the level of human disturbance and conservation of the areas are influencing the natural occurrence, species diversity and development of the trees. Height, DBH and shape are good indicators to assess the growth of the tree community and relate them to soil chemical properties; LDA and legal reserve presented higher natural occurrence, number of individuals and number of species. In the riparian forest, basal area values, height, shape and chemical soil properties were higher. From the 97 species found, six have the potential to be used in a program of genetic conservation in situ. They are: Astronium fraxinifolium, Terminalia argentea, Curatella americana, Cupania vernalis, Qualea jundiahy and Andira cuyabensis.

Retificador entrelaçado com elevado fator de potência para operação de um veículo trólebus alimentado por redes em CA Ou CC

This paper presents the development and the main results for an interleaved boost rectifier operating as a special input power stage for a trolleybus type vehicle, allowing its feeding by alternate current (AC) or direct current (DC) distribution power systems. When feeding with two wires (single phase) alternate current distribution system, the converter accomplish active power factor correction, providing a relatively sinusoidal current with low total harmonic distortion (THD) and fully complying with IEC 61000-3-4 standards. In addition, a management control system promotes the required automatic operation changes for the proposed rectifier when the vehicle is changing from the DC distribution power system to the AC distribution power system and vice-versa, keeping its original electrical DC system characteristics for the adjustable speed driver sub-system. The main experimental results for a prototype rated at 150kW are presented, considering its application for a trolleybus with DC adjustable speed driver, demonstrating the proposed converter benefits and the possibility of AC feeding system for trolleybus type vehicle.

Microinversor integrado ao módulo fotovoltaico para sistemas conectados à rede elétrica utilizando controlador ressonante

This paper shows the modeling and control of a single-phase full-bridge inverter with high-frequency transformer that may be used as part of a two-stage converter with transformerless DC-DC side or as a single-stage converter (simple DC-AC converter) for grid-connected PV applications. The inverter is modeled in order to obtain a small-signal transfer function used to design the P+Resonant current controller. A highfrequency step-up transformer results in reduced voltage switches and better efficiency compared with converters in which the transformer is used on the DC-DC side. Simulations and experimental results with a 200 W prototype are shown. 1
