Looking at the Gregory-Laflamme instability through quasinormal modes
(AMER PHYSICAL SOC, 2008)
We study evolution of gravitational perturbations of black strings. It is well known that for all wave numbers less than some threshold value, the black string is unstable against the scalar type of gravitational perturbations, ...
Newtonian perturbations on models with matter creation
(AMER PHYSICAL SOC, 2011)
Creation of cold dark matter (CCDM) can macroscopically be described by a negative pressure, and, therefore, the mechanism is capable to accelerate the Universe, without the need of an additional dark energy component. In ...
Dynamic transitions in a three dimensional associating lattice gas model
(AMER INST PHYSICS, 2010)
The aggregation of interacting Brownian particles in sheared concentrated suspensions is an important issue in colloid and soft matter science per se. Also, it serves as a model to understand biochemical reactions occurring ...
Soliton dynamics at an interface between a uniform medium and a nonlinear optical lattice
(AMER PHYSICAL SOC, 2009)
We study trapping and propagation of a matter-wave soliton through the interface between uniform medium and a nonlinear optical lattice. Different regimes for transmission of a broad and a narrow solitons are investigated. ...
Effect of solvent hydration and temperature in the deacidification process of sunflower oil using ethanol
(ELSEVIER SCI LTD, 2009)
This work presents liquid-liquid experimental data for systems composed of sunflower seed oil, ethanol and water from 10 to 60 degrees C. The influence of process variables (temperature (T) and water concentration in the ...
Vegetable Oils Deacidification by Solvent Extraction: Liquid-Liquid Equilibrium Data for Systems Containing Sunflower Seed Oil at 298.2 K
(AMER CHEMICAL SOC, 2010)
Liquid-liquid equilibrium experimental data for refined sunflower seed oil, artificially acidified with commercial oleic acid or commercial linoleic acid and a solvent (ethanol + water), were determined at 298.2 K. This ...
The Impacts of Inter-El Nino Variability on the Tropical Atlantic and Northeast Brazil Climate
(AMER METEOROLOGICAL SOC, 2011)
In this study, observations and numerical simulations are used to investigate how different El Nino events affect the development of SST anomalies in the Atlantic and how this relates to the Brazilian northeast (NE) ...
Formulation of a tropical town energy budget (t-TEB) scheme
(SPRINGER WIEN, 2010)
This work describes the tropical town energy budget (t-TEB) scheme addressed to simulate the diurnal occurrence of the urban heat island (UHI) as observed in the Metropolitan Area of Rio de Janeiro (MARJ; -22A degrees S; ...
Phase equilibria study of systems composed of refined babassu oil, lauric acid, ethanol, and water at 303.2 K
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2011)
Deacidification of vegetable oils can be performed using liquid-liquid extraction as an alternative method to the classical chemical and physical refining processes. This paper reports experimental data for systems containing ...
Densities and Viscosities of vegetable oils of nutritional value
(AMER CHEMICAL SOC, 2008)
Densities and viscosities of five vegetable oils (Babassu oil, Buriti oil, Brazil nut oil, macadamia oil, and grape seed oil) and of three blends of Buriti oil and soybean oil were measured as a function of temperature and ...
