Adsorption micro calorimeter : Design and electric calibration
(Springer, 2009-08-06)
In this work, it is described an innovative heat flux micro calorimeter Tian-Calvet type designed to measure adsorption heats and reactions as well as adsorption isotherms. It consists in an adsorption instrument for ...
Estrutura de prática e idade no processo adaptativo da aprendizagem de uma tarefa de "timing" coincidente
(Escola de Educação Física e Esporte da Universidade de São Paulo, 2010)
O objetivo desse estudo foi investigar os efeitos de diferentes estruturas de prática no processo adaptativo da aprendizagem de uma tarefa de "timing" coincidente em função da idade. Crianças (n = 40), adultos (n = 47) e ...
Communication: Localized molecular orbital analysis of the effect of electron correlation on the anomalous isotope effect in the NMR spin-spin coupling constant in methane
(American Institute of Physics, 2014-10-15)
We discuss the effect of electron correlation on the unexpected differential sensitivity (UDS) in the 1J(C-H) coupling constant of CH4 using a decomposition into contributions from localized molecular orbitals and compare ...
Binding of chloroquine to ionic micelles: Effect of pH and micellar surface charge
(Elsevier Science BvAmsterdamHolanda, 2014)
On the Casimir energy for a massive quantum scalar field and the cosmological constant
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2009)
We present a rigorous, regularization-independent local quantum field theoretic treatment of the Casimir effect for a quantum scalar field of mass mu not equal 0 which yields closed form expressions for the energy density ...
The dynamics of shrinking and expanding drug-loaded microspheres: A semi-empirical approach
(ELSEVIER SCIENCE BV, 2014-07-16)
The dynamics of shrinking and expanding drug-loaded microspheres were studied using a diffusion equation in spherical coordinates. A movable boundary condition was incorporated as a convection term in the original model. ...
Controlled drug release from a spheroidal matrix
(ELSEVIER SCIENCE BV, 2019-01-01)
Drug transport through a spheroidal matrix was studied using Fick's second law of diffusion in spherical coordinates. The prolate spheroid-shaped geometry was described by a small angular deformation applied at the surface ...
A three-dimensional semi-analytical solution for predicting drug release through the orifice of a spherical device
(ELSEVIER SCIENCE BV, 2016-07-25)
Three-dimensional solute transport was investigated for a spherical device with a release hole. The governing equation was derived using the Fick's second law. A mixed Neumann-Dirichlet condition was imposed at the boundary ...
Sliding mode for detection and accommodation of computation time delay fault
(Elsevier B.V., 2009-10-01)
Computation time delay in digital control systems reduces its robustness as well as degrades its performance. In this paper, the computation time delay is assumed to be constant and smaller than the sampling time and is ...
Kinetics of the polarization reversal process in a non-constant applied electric field and the generalized superposition principle
(1996-12-01)
We analyze the results on polarization reversal by H. von Seggern and T. T. Wang (J. Appl. Phys., 56, 2448 (1984)) under the assumption of validity of a superposition principle in terms of a conveniently defined intrinsic ...
