Análise da durabilidade do concreto de alto desempenho com adição de cinza de casca de arroz e borracha de pneu

Since the Seventies, there has been a growing degradation of concrete structures in Brazil. For that reason, much research has been made on the durability of those structures, aiming at contributing towards quality improvement and reduction of maintenance and repair costs. This study evaluates the behavior of the durability of high-performance concrete with additions, replacing part of the cement and aggregates with rice husk ash and tire rubber, respectively. Durability tests were carried out in which concrete was subjected to several degradation processes, such as the action of water, temperature, salts and acid solution. The results indicated that the addition of active silica or rice husk ash, both with tire rubber did not worsen the durability of concrete. In fact, rubber proved to be very effective in preventing the action of chemical agents, high temperatures and the penetration of water. Rice husk ash, despite the larger diameter of particles, had similar results to that of the active silica.

Painel particulado composto por casca de eucalipto na camada intermediária

This work was developed to evalute the physical and mechanical properties of a panel of three particle layers from the test specification of NBR 14810-3 (2006), using wood of Eucalyptus sp. and Eucalyptus saligna and Eucalyptus urograndis bark. The mechanical properties were evaluated to obtain the bending modulus of rupture (MOR) and modulus of elasticity (MOE) and Internal bond. The physical properties were obtained thickness sweeling, water absorption, moisture content and board density. Were evaluated four different compositions of panels containing 5, 10, 15 and 20% in the inner layer of bark. The results were compared with the Brazilian standard NBR 14810-2 (2006) and also with studies in the literature. The panels produced were adequate to all the optimal values suggested by the standard only in the composition with 5% skin in the inner layer. The other treatments showed satisfactory results in all tests except for moisture content

Atividade in vitro do extrato hidroalcoólico da casca de Astronium fraxinifolium (Anacardiaceae) sobre trofozoítos de Giardia duodenalis

As investigações conduzidas para avaliar novas substâncias para o tratamento da giardíase justificam-se pelo fato dos medicamentos convencionais apresentarem inconvenientes relacionados à toxicidade, à resistência e aos custos. Diante disso, a busca por novas alternativas terapêuticas tem despertado grande interesse, principalmente, entre os extratos de plantas, produtos complexos com diferentes atividades biológicas e farmacológicas. Considerando que nas infecções por Giardia, a diarréia é um dos principais sintomas, tem sido crescente o interesse em se investigar o efeito de extratos de plantas com atividade antidiarréica. Com isso, o presente trabalho foi desenvolvido com o objetivo de avaliar in vitro o efeito do extrato hidroalcoólico da casca da planta Astronium fraxinifolium, espécie típica do Cerrado brasileiro e empregada na medicina popular no tratamento contra inflamações, diarréias e úlceras gástricas. Para este fim, avaliou-se a atividade sobre o crescimento e aderência de trofozoítos de cepa autóctone de Giardia duodenalis isolada e axenizada em Botucatu, São Paulo. Em todos os ensaios, 105 trofozoítos da cepa BTU-11 foram inoculados em tubos contendo 4,5ml de meio TYI-S-33 e 100μl do extrato nas concentrações de 125; 250; 375 e 500 μg/ml. Para avaliar a atividade sobre o crescimento, os parasitas foram incubados com o extrato durante 24, 48 e 72 horas a 37°C. Nos experimentos que verificaram o efeito sobre a aderência, somente os parasitas aderidos às paredes dos tubos foram incubados com o extrato, durante 24 e 48 horas a 37°C. Em cada ensaio, os trofozoítos recuperados foram contados em câmara de Neubauer e a atividade sobre... (Resumo completo, clicar acesso eletrônico abaixo)

Determinação da temperatura para inativação da urease em amostras de casca e farelo de soja

s not degraded in the rumen but destroy ureasis. Soybean meal is one of the protein ingredients commonly used in formulations of animal feeds. In the diets of monogastric bran has high protein content provided by a greater separation of soybean hulls. For the ruminant protein value of the meal is lower with the inclusion of soybean hulls to reduce the level of protein. With the increased consumption of meal high protein, due to increases in production of pigs and poultry in recent years, increasing the availability of soybean hulls on the market, this is because soybean hulls is little understood in the feeding of monogastric . In this context, the main objective of this study was to determine the times and temperatures needed to ensure the effective inactivation of ureasis present in the bran and soybean hulls. According to the assessments, to make the determination of temperatures and times required for the inactivation of ureasis present in the bran and soybean hulls are 170 º C and 25 minutes for soybean meal and 140 ° C 10 minutes for soybean hulls, respectively

Aplicação do ciclo rankine orgânico alimentado termicamente pela queima da casca do arroz e resíduos de madeira

With the growing world energy demand mainly from developing countries like Brazil, Russia, India and China, the search for efficient sources of energy becomes a challenge for the coming years. Among the most widely used alternative sources, biomass is the one that grows in a more pronounced way. This study will assess the real possibility of having it as a heat source in an Organic Rankine Cycle, which employ heat transfer fluids as working fluids instead of water. From a regional data collection in agricultural production and their potential rice production and the resulting husk was defined as more appropriate. The availability of husks together with an amount of eucalyptus wood, provided by a company in the region on a monthly basis, were analyzed, and the low participation of the wood was discarded by the thermal contribution of little significance. Based on this, it was established the calorific value of fuel for thermodynamic calculations and the cycle to be used. It was then carried out the choice of working fluid from the literature and their availability in the library of software used for the simulations, the Engineering Equation Solver - ESS. The fluid most appropriate for the burning of biomass, Octamethyltrisiloxane (OMTS), was not included in the software and so the R227ea and R134a were selected. After the initial parameters modeling definition, as condensing temperature, efficiency and live steam conditions, the simulations were performed, and only the R227ea remained within the feasible thermodynamic and technological ranges. With this fluid the turbine power output was 265.7 [kW] for a scenario of 24 hours/day burning, 800.3 [kW] to biomass burning for 8 hours/day and 2134 [kW] for burning only 3 hours/day. The thermal efficiency of the cycle remained in the range of 6%, and for plants operating with the most... (Complete Abstract click eletronic access below)
