1. FUZZY MODELING OF THE EFFECTS OF DIFFERENT IRRIGATION DEPTH IN RADISH CROP. PART II: BIOMETRIC VARIABLES ANALYSIS
ABSTRACT In order to estimate the response of biometric variables in different irrigation depths in radish crop, as well as their relations in the development of the crop, a fuzzy mathematical analysis was carried out from irrigation with depths of different percentages of the crop evapotranspiration (ETc), using Gaussian pertinence functions for the input v

2. ESTIMATION OF WOOD TOUGHNESS IN BRAZILIAN TROPICAL TREE SPECIES
ABSTRACT Wood has been used for several purposes such as in civil and rural construction. Knowing wood mechanical behavior under short-term loading is essential for safer structural designs. However, wood toughness is a mechanical property little investigated for this purpose. Thus, this study aimed to evaluate, using exponential and polynomial regression mo

3. Cryopreservation of semen from goats fed a diet supplemented with flaxseed
RESUMO O objetivo com o estudo foi avaliar o efeito da inclusão de semente de linhaça na dieta de machos caprinos sobre a resistência do sêmen frente ao processo de criopreservação. Foram utilizados 16 machos, os quais foram distribuídos em quatro grupos e receberam dieta suplementada com 0, 4, 8 e 12% de semente de linhaça, durante um período de 60

4. Sward structure and ingestive behavior of cows in tropical pastures managed under different forage allowances
RESUMO O objetivo foi avaliar como mudanças na estrutura de pastos de Brachiaria brizantha cv. Marandu, sob diferentes ofertas de forragem (OF) de 4, 7, 10 e 13kg MS/100kg PC, afetam o comportamento animal durante um período de avaliação de dois anos. O delineamento utilizado foi em blocos ao acaso, com três repetições (piquetes). A altura do dossel,

5. Effect of adenosine concentration on quality of cooled ram semen
ABSTRACT This study analyzed the adenosine concentration on quality of ram semen in different refrigerated storage times at 5 °C. The design was in blocks with repeated-measures factorial design. Five levels of adenosine and four refrigeration times were considered as fixed effects and the animal as random effect (block). Ram semen was diluted with Andromed

6. Digestible lysine requirement for European laying quail
ABSTRACT. The experiment was carried out to evaluate the productive performance of European quails (Coturnix coturnix) in the production phase, fed with diets containing different levels of digestible lysine. A total of 175 female quails, aged 65 days, were randomly distributed in a completely randomized design with five treatments and five replicates per tr

7. PHASE BEHAVIOR DATA AND THERMODYNAMIC MODELING OF THE BINARY SYSTEM {CO2 + COUMARIN} AT HIGH PRESSURES
Abstract In this work, vapor - liquid (VLE) equilibrium for the binary system carbon dioxide (1) + coumarin (2) at high pressures was measured by a static synthetic method using a variable-volume view cell. Experimental data were obtained in the temperature range of 318 - 338 K and pressures up to 20 MPa. Coumarin molar fraction ranged from 3.0x10-3 to 6.0x1

8. A demanda domiciliar por arroz no Brasil: abordagem por meio do sistema Quaids em 2008/2009
Resumo O arroz é um alimento básico na dieta do brasileiro; contudo, o lento crescimento de seu consumo tem impactos diretos na expansão do setor. Para compreender os fatores que afetam esse consumo e suas inter-relações com outros alimentos foram estimadas, neste estudo, as elasticidades da demanda por dez alimentos nos domicílios brasileiros, utiliza

9. Performance, ingestive behavior and carcass traits of lambs fed rations containing soybean cake
ABSTRACT. The aim of this study was to evaluate the performance, ingestive behavior and carcass traits of crossbred Dorper x Santa Inês lambs fed rations containing soybean cake. Twenty-four lambs (4 months of age and 24.3 ± 3.1 kg BW) were used in a completely randomized design with four treatments and six replicates. Treatments were the inclusion of 50,

10. Composition and ecology of a snake assemblage in an upland forest from Central Amazonia
Abstract: Most species of Amazonian snakes have wide geographic distributions. However, local environmental factors influence the formation of assemblages in different localities. In this study, we investigated the composition of the assemblage and the effect of environmental variables on the distribution of the species inhabiting an upland forest in the Exp

11. Optimization of polyphenols and acceptability of jelly candies with ginger ( Zingiber officinale R.) extract and honey with Mixture Design
Abstract The objective of this work was to optimize total polyphenols content, firmness, sweetness and general acceptability of jelly candies developed with ginger extract and six proportions of sucrose, honey and glucose. To study the effect of proportions, the Simplex Lattice Mixture Design was used. The design was replicated for four levels of ginger ext

12. An Improved Dynamic Contact Model for Mass–Spring and Finite Element Systems Based on Parametric Quadratic Programming Method
Abstract An improved dynamic contact model for mass-spring and finite element systems is proposed in this paper. The proposed model avoids the numerical troubles of spurious high-frequency oscillations for mass-spring and finite element systems in dynamic contact problems by using the parametric quadratic programming technique. The iterative process for det
