13. Investigando o processamento de narrativas na lesão cerebral de hemisfério direito
Advances in neuroscience have allowed us a more refined study of language processing, and hemispheric specialization. In relation to text processing, previous research has indicated a greater involvement of the left hemisphere (LH), associated with text integration, which means, the understanding of macrostructure, and the creation of an appropriate situatio

14. Solution of hyperbolic bioheat transfer problems by numerical green's functions: the ExGA-linear θ method
This paper presents a time-domain formulation called Explicit Green's approach (ExGA) linear θ method for the solution of the bioheat equation. Starting from the hyperbolic bioheat equation, which includes the parabolic one as a special case, the linear method is incorporated into the standard ExGA time marching scheme. The numerical Green's function is fir

15. A transformation of variables technique applicable to the boundary element method to simulate a special class of diffusive-advective potential problems
This paper describes a novel Boundary Element Technique developed for application to one-dimensional and a class of two-dimensional diffusive-advective potential problems. It is based on transformation of variable procedure to establish an integral equation inverse sentence, dealing only with boundary variables, using a fundamental solution associated with a

16. Fundamental solution in the theory of micropolar thermoelastic diffusion with voids
In the present article, we construct the fundamental solution of system of differential equations in the theory of micropolar thermoelastic diffusion with voids in case of steady oscillations in terms of elementary functions. Some basic properties of the fundamental solution are also established. Some special cases are also discussed. Mathematical subject cl

17. Construction of Lyapunov functions for the estimation of basins of attraction
Technical systems are often modeled through systems of differential equations in which the parameters and initial conditions are subject to uncertainties. Usually, special solutions of the differential equations like equilibrium positions and periodic orbits are of importance and frequently the corresponding equations are only set up with the intent to descr

18. Da atribuição de autoridade ao precedente judicial no processo civil brasileiro : o guardião da lei federal e os juizados especiais civeis
The work analyzes the attribution of authority to judicial precedent on brazilian civil procedure, focusing on decisions of brazilian Superior Court of Justice and its influence concerning state small claims courts, in order to demonstrate that this microsystem can t be distant from the precedents established by that court involving interpretation of federal

19. Towards a phylogenetic classification of Lychnophorinae (Asteraceae: Vernonieae) / Rumo a uma classificação filogenética de Lychnophorinae (Asteraceae: Vernonieae)
A phylogenetic hypotesis of American Vernonieae based on three molecular regions (ITS, ndhF, rpl32-trnL) and on a morphological dataset reveals the existence of four main lineages in the group. Three of these lineages correspond, with a few adjustments, to subtribes Chrestinae, Lychnophorinae and Vernoniiae. The last lineage is mainly composed of Lepidaploin

20. A percepÃÃo na gestÃo das bibliotecas universitÃrias da Universidade Federal do CearÃ: paralelo entre a visÃo dos gestores e usuÃrios / The perception in the management of the university libraries of the Federal University of The CearÃ: parallel enters the vision of the managers and users
The changes that if gestam in the society contemporary affect all the scopes of the life human being and societÃria, amongst them the interior of the organizations. With effect, if they find the libraries university, surrounding where already certain concerns with the changes of position on the part of the professionals are observed and, in special, of whom

21. Los seguros de salud mexicanos: cobertura universal incierta
The Mexican health system is comprised of the Department of Health, state labor social security and the private sector. It is undergoing a reform process initiated in 1995 to achieve universal coverage and separate the regulation, financing and service functions; a reform that after fifteen years is incomplete and problematic. The scope of this paper is to a

22. Estimates of cosmic radiation dose received by aircrew of DCTA's flight test special group
Abstract: Aircraft crews are subjected to radiation doses of cosmic origin in the regular exercise of their functions. The present paper gives an estimate of typical doses received by crews of the Flight Test Special Group of DCTA (GEEV) from July 2007 to November 2009. The dose estimates were performed using the CARI-6 and PCAIRE codes and were compared wit

23. Narciso sem espelho
One of the characteristics of contemporary society is the validation of the functions and attributes of image: looking, viewing and seeing can be considered as a hyper-cognization of vision. To move from the behavior of those who are able to see and those who are blind can mean much more than the contrasts between seeing and not seeing, between light and dar

24. Regressão de dados binários : distribuição Weibull
In this work a new class of models for binary data based on Weibull distribution is introduced. A review is made of the most known linkage functions. This class of models has as special case the complementary log-log model and approximates well the logit and probit models. Three real data sets are given to compare the proposed model with many others. In one
