1. Effect of the dietary level of cull pinto beans (Phaseolus vulgaris) on ruminal fermentation, kinetics, and digestibility of hair lambs
ABSTRACT The objective was to evaluate the effect of three levels of cull pinto beans (CPB; Phaseolus vulgaris) on ruminal fermentation, kinetics, and nutrient digestibility in hair lambs. Six cannulated lambs averaging 56.6±3.8 kg were used and were randomly assigned to one of three treatments. Treatments were: 0.0 kg kg−1 of CPB in the supplement (contr

2. A Model for Homogenization of Linear Viscoelastic Periodic Composite Materials with Imperfect Interface
Abstract In this paper, a micromechanical extension of the finite-volume direct averaging micromechanics theory (FVDAM) is presented for evaluation of the homogenized relaxation moduli of linear viscoelastic unidirectional fiber reinforced composites with periodic microstructures. Such materials are assumed as composed of repeating unit cell with arbitrary i

3. Forecasting Inflation with the Phillips Curve: A Dynamic Model Averaging Approach for Brazil
O presente estudo propõe uma curva de Phillips generalizada para prever a inflação brasileira no período 2003:M1–2013:M10. Neste sentido, emprega-se o método Dynamic Model Averaging, que permite tanto a evolução do modelo quanto parâmetros variando no tempo. O procedimento consiste basicamente em representação de estado-espaço e estimação via

4. Robustez de regressões de crescimento frente à incerteza sobre a especificação do modelo: quão robustos são os regressores para o caso brasileiro?
Resumo Embora haja uma vasta literatura que busca identificar regressores robustos capazes de influenciar o crescimento econômico em âmbito internacional, esse tema ainda carece de pesquisas que apresentem resultados estatisticamente satisfatórios para o caso brasileiro. O presente artigo busca contribuir para a identificação de variáveis robustas capa

5. Effective transport properties for the pyridine-granular activated carbon adsorption system
In this work, the kinetics of pyridine adsorption onto granular activated carbon was studied from the point of view of an up-scaling process by using the method of volume averaging. The pore and surface effective diffusivities were estimated by supposing simple microscale geometries (ordered media of cylinders and spheres) and those of images processed from

6. Métodos clássicos e alternativos para a análise de dados de fMRI e EEG-fMRI simultâneo em indivíduos assintomáticos, pacientes com epilepsia e com estenose carotídea / Classic and alternative methods for fMRI and simultaneous EEG-fMRI data analysis in asymptomatic subjects, patients with epilepsy and carotid stenosis
O mapeamento das respostas BOLD (Blood Oxygenation Level Dependent) constitui etapa importante nos experimentos de imagem funcional por ressonância magnética (Functional Magnetic Resonance Imaging fMRI) e de EEG-fMRI simultâneo. Em sua grande maioria, a análise de dados de fMRI e de EEG-fMRI está baseada no modelo linear geral (General Linear Model GLM)

7. Simulation of two-dimensional high reynolds number wake flows with the use of filtered lagrangian navier-stokes equations
This work presents a method for numerical simulation of viscous fluid flows based on the use of filtered Lagrangian Navier-Stokes equations. It is based on the hypothesis that the small scale motions are responsible for the homogenization of the physical properties in infinitesimal fluid parcels through a mixing process, mathematically expressed as a spatial

8. The numerical modeling of thermal turbulent wall flows with the classical κ - ε model
The goal of this work is to propose a new methodology to simulate turbulent thermal wall flows using the classical κ - ε model. The focus of this approach is based on the manner used to implement heat flux boundary conditions on the solid walls. In order to explain and to validate this new algorithm, several test cases are presented, testing a great range

9. Exact photocount statistics : lasers near threshold
A previously constructed laser model with quantum (noncommuting) noise sources was shown to lead near threshold to a quantum rotating-wave Van der Pol oscillator. A full dynamical correspondence between quantum and classical random processes allows one to compute the average of any time-ordered, normal-ordered operator function by averaging the associated fu

10. Survivorship rates of adult Anolis mariarum (Squamata: Polychrotidae) in two populations with differing mean and asymptotic body sizes
We compared adult survivorships in two populations of the lizard Anolis mariarum with different mean and asymptotic body sizes to examine one prediction of age-specific mortality theory; that populations that experience higher adult mortality should exhibit earlier maturation and smaller adult body sizes. We used a maximum likelihood approach to evaluate dif

An important step in the modelling of hydraulic networks, calibration makes it possible to predict the behavior of physical parameters essential to decision-making. The present study used inverse transient analysis with a genetic algorithm to calibrate pipe roughness in a water distribution network with simulations based on variable parameters such as mutati

The knowledge anastomosis groups (AG) of Rhizoctonia solani populations, which cause cotton damping-off and sudden death in Brazil, the pathogen morphological features and disease epidemiology foster the establishment of more efficient disease management strategies in the field. Initially, 51 isolates were obtained from cotton seedlings originated from crop
