13. Artificially cooling of onion bulbs stored in brickwork-patterned vertical silos
RESUMO A cebola é a terceira hortaliça mais consumida no mundo, ao lado da batata e do tomate. Sua conservação é influenciada pela umidade e temperatura e, as maiores perdas pós-colheita ocorrem devido à falta de infraestrutura no armazenamento. O objetivo do presente trabalho foi avaliar o efeito do resfriamento parcial de silo vertical na conservaç

14. Climatic Response of Cedrela fissilis Radial Growth in the Ombrophilous Mixed Forest, Paraná, Brazil
ABSTRACT We examined the climatic response of Cedrela fissilis radial growth based on precipitation, air relative humidity, temperature and monthly thermal amplitude. It was intended to assess how the secondary growth of C. fissilis is influenced by the climatic variables and which one are the best growth predictors in Ombrophilous Mixed Forest, southern Bra

15. Balanço de Energia, Emissão Foliar e Eficiência do Uso da Radiação pela Cana-de-Açúcar em Cultivo sem e com Palhada
Resumo Nas últimas décadas houve mudança no sistema de colheita e manejo da palhada em canaviais de todo o Brasil, visando atender a legislação vigente e reduzir custos. A deposição de resíduos culturais sobre o solo, contudo, modifica as características micrometeorológicas do ambiente. Este trabalho reporta um estudo conduzido em Juazeiro-BA, para

16. Effect of temperature gradients on the behaviour of jointed plain concrete pavements
Resumo Em muitos países da América Latina os pavimentos de concreto com juntas (JPCP) são calculados usando os métodos da “American Association of State Highway and Transportation Officials (AASHTO) ou da “Portland Cement Association” (PCA), os quais não levam em consideração explicitamente as condições climáticas específicas de cada região

17. Photo-selective shade nets on the production and quality of sugarcane plantlets
RESUMO O Brasil é o maior produtor mundial de cana-de-açúcar (Saccharum officinarum L.), e pesquisas voltadas à propagação têm proporcionado maior qualidade na produção. Objetivou-se averiguar o efeito da variação dos elementos micrometeorológicos na sobrevivência e qualidade de mudas pré-brotadas de cana-de-açúcar. A pesquisa foi realizada e

18. Multivariate analysis of the behavior and physiology of Girolando heifers in pasture
RESUMO Objetivou-se avaliar o efeito térmico na mudança comportamental e fisiológica de novilhas girolando, por meio da análise de componentes principais. A pesquisa foi conduzida na região Agreste do estado de Pernambuco, Brasil. Foram utilizadas três novilhas submetidas ao sistema de pastejo contínuo. Para determinação do efeito térmico sobre os

19. Effect of drying methods on long term storage of hazelnut
Abstract This research was conducted to determine the chemical traits of Ordu Levant hazelnuts that were dried with sun–drying [on concrete ground (CG), grass ground (GG)], or in drying machine (DM) during 24 months of storage (2014-2016) at 20-25 °C and 70-90% relative humidity. Drying process continued 39 h for CG and GG, and 23 h for DM. Sun–drying

20. Effect of the degree of acetylation, plasticizer concentration and relative humidity on cassava starch films properties
Abstract The objective of this study was to develop films with reduced hygroscopicity and improved mechanical properties from acetylated cassava starch. For that, an acetylation procedure using acetic anhydride as the esterification reagent was performed, resulting in starch acetates with degrees of substitution (DS) of 0.6 (S0.6) and 1.1 (S1.1). Twelve fil

22. Understanding heat stress in beef cattle
ABSTRACT Thermal stress is the result of a misbalance between heat produced or gained from the environment and the amount of heat lost to the environment. The level of thermal stress can range from minor or no effect to death of vulnerable animals. Under summertime conditions, thermal stress results in hyperthermia or heat stress. Heat stress in feedlot catt

23. Efecto de la concentración del silano MTMO sobre la protección contra la corrosión de acero electrocincado
ABSTRACT Superficial pretreatments based on silanes are one of the prominent alternatives to replace chromates as temporary protectors from the action of aggressive environments to metallic substrates. The barrier effect afforded by the silane film makes porosity, thickness and film homogeneity important issues in the protective effect. In the present work,

24. Lubricated Conditions Imposed on Coating Multi-layer on Wear Resistance Under Cr2O3 Effect
Lubricated pin-on-disk sliding wear tests were performed on applied to Al-0.1Mg-0.35Ni-Si Alloy by using the spray coating method has been investigated. Different loads were 5, 10, and 15 N at a sliding velocity, 1.32 m/s at room temperature and 60% relative humidity. The surfaces were analyzed by using X-ray diffraction the residual (XRD), energy dispersive
