1. Structural Model and De-Intercalation Kinetics of Kaolinite-Methanol-Sodium Stearate Intercalation Compound
Kaolinite-methanol-sodium stearate intercalation compound (Ka-MeOH-SS) was prepared by intercalation of kaolinite with dimethyl sulfoxide (DMSO) followed by displacing of DMSO with methanol and methanol by sodium stearate. The sample was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), thermal analysis (thermogravimet

2. A distribuição log-logística exponenciada geométrica: dupla ativação / The exponentiated log-logistic geometric distribution: dual activation
In this work, we propose a new distribution with four parameters the so called exponentiated log-logistic geometric distribution based on a double mechanism of activation for modeling lifetime data. For this new distribution, we study the density function, cumulative distribution, survival function and the failure rate function which allows major harzad rate

3. A Stochastic discount factor approach to asset pricing using panel data asymptotics
Using the Pricing Equation in a panel-data framework, we construct a novel consistent estimator of the stochastic discount factor (SDF) which relies on the fact that its logarithm is the "common feature" in every asset return of the economy. Our estimator is a simple function of asset returns and does not depend on any parametric function representing prefer

5. Probability distribution and sample dimension for particle size in forage grasses / Distribuição de probabilidade e dimensionamento amostral para tamanho de partícula em gramíneas forrageiras
The purpose of this study was to identify the probability distribution of variable particle size in forages grasses and to do a sample dimension. For this was carried out an exploratory analysis of the data obtained from the experiment planned in randomized blocks. Each sample of the overall data was adjusted to Normal, Gama, Beta and Weibull distributions.

6. Composição corporal e exigências nutricionais de bezerros holandeses do nascimento aos 100 dias de idade / Body composition and nutritional requirements of Holstein calves from birth to 100 days of age
Body composition and net requirements for energy, protein, calcium, phosphorus, magnesium, sodium and potassium were estimated by using 20 Holstein calves, non-castrated, with average initial body weight of 37.5 kg. The animals were distributed in randomized blocks, with 16 animals subjected to treatment that consisted of two ages of weaning, with the same c

7. Composição corporal e exigências nutricionais de bovinos Nelore castrados em pastejo / Body composition and nutritional requirements of Nellore steers under grazing
The present work was done aiming to determine the body composition and energy, protein, calcium (Ca), phosphorus (P), magnesium (Mg), potassium (K) and sodium (Na) requirements. Twenty four Nellore steers averaging 371 14 kg of initial body weight and 26 months of age were used. Four calves were slaughtered at the beginning of the experiment (reference group
