1. Respostas a lógicas institucionais conflitantes: um estudo da participação nos lucros e resultados
Resumo A participação nos lucros e resultados (PLR), desde a década de 1990, encontra-se inserida no cotidiano das empresas brasileiras. A intenção deste artigo foi investigar como uma organização responde a demandas institucionais conflitantes durante todo o período entre a adoção e o esmaecimento de uma prática. Foi realizado um estudo de caso l

2. Biophysical controls of evapotranspiration in cowpea cultivation under different water regimes
RESUMO Objetivou-se com esse trabalho analisar as variações do fator desacoplamento, das condutâncias aerodinâmica e estomática para o feijão-caupi submetido a diferentes níveis de disponibilidade hídrica durante os estádios fenológicos reprodutivos da cultura. O estudo foi conduzido no município de Castanhal, situado no nordeste do estado do Par�

3. Strategic circumvention of regulations: the judicialization of the Brazilian private health system
Resumo O artigo busca aprofundar a compreensão sobre as evasões sucessivas às regulações pelas organizações, de modo a estabelecer se é possível caracterizá-las como ações intencionais, enquanto a literatura institucional analisa o descolamento e a evasão como atividades esporádicas. Nesse sentido, o artigo analisa as respostas adotadas pelas c

4. Baroreflex sensitivity in frailty syndrome
Frailty is related to a decrease in the physiological reserves, which causes difficulties in maintaining homeostasis. An example of physiological mechanisms for cardiovascular homeostasis is the baroreflex. The aim of this study was to compare baroreflex among frail, prefrail, and nonfrail individuals, in supine and orthostatic positions. Community-dwelling

5. Growth and reproduction in captivity unveils remarkable life-history plasticity in the smallnose fanskate, Sympterygia bonapartii (Chondrichthyes: Rajiformes)
ABSTRACT We analyzed growth and reproduction of captive-born smallnose fanskates Sympterygia bonapartii. Egg cases were obtained from oviposition of two females caught in the wild and held at Temaikèn Aquarium. Following hatching, growth was analyzed in 13 females and 21 males until sexual maturity. Pattern of oviposition activity and reproductive performan

6. Updating of a Nonlinear Finite Element Model Using Discrete-Time Volterra Series
Abstract In this study, the discrete-time Volterra series are used to update parameters in a nonlinear finite element model. The main idea of the Volterra series is to describe the discrete-time output of a nonlinear system using multidimensional convolutions between the Volterra kernels represented in a Kautz orthogonal basis and the excitations. A metric b

7. Multidisciplinary Design Optimization of UAV Under Uncertainty
ABSTRACT: Uncertainty-based multidisciplinary design optimization considers probabilistic variables and parameters and provides an approach to account for sources of uncertainty in design optimization. The aim of this study was to apply a decoupling uncertainty-based multidisciplinary design optimization method without any dependence on probability mathemati

8. Rare Earth Element Concentrations in Brazilian Benchmark Soils
ABSTRACT: Studies regarding background concentrations of rare earth elements (REEs) are scarce and have mainly focused on a limited number of soil types from the northern hemisphere. The aim of this study was to determine REE concentrations in thirty-five benchmark soils of Brazil. Composite soil samples were taken from areas under native vegetation or with

9. The Control of Asymmetric Rolling Missiles Based on Improved Trajectory Linearization Control Method
ABSTRACT According to motion characteristic of an asymmetric rolling missile with damage fin, a three-channel controlled model is established. The controller which is used to realize non-linear tracking and decoupling control of the roll and angle motion is introduced based on an improved trajectory linearization control method. The improved method is compos

10. NUMERICAL SIMULATION OF THE INCOMPRESSIBLE TURBULENT FLOW OF A BINARY MIXTURE OF AIR-WATER VAPOR: APPLICATIONS IN DRYING PROCESS
Abstract The present work deals with numerical simulation of the incompressible turbulent flow of a binary mixture air-water vapor inside channels. Calculations are performed using the RANS (Reynolds Average Navier-Stokes Equations) formulation in addition to the standart k-ε turbulence model. The mathematical model is discretized by a finite difference sch

11. MULTIVARIABLE OPTIMAL CONTROL OF A HEAT EXCHANGER NETWORK WITH BYPASSES
Abstract Heat exchanger networks present an interesting control problem due to coupling among process streams. In this work, the linear quadratic regulator (LQR), a feedback optimal control technique, is used to control stream temperatures on a laboratory scale heat exchanger network, through bypass manipulation, in a multivariable system. The LQR design was

12. Numerical Study of the b-Ξ Flame Wrinkling Combustion Model in Oracles Test Rig
ABSTRACT: Numerical modeling of premixed combustion is important for a wide range of machines and systems focusing on compliance with the increasing pollutants reduction requirements. However good industrial numerical combustion models need a practical requiring, in this way, a balance between speed and accuracy. The flamelet models are suitable for this pur
