1. Effect of contrast and gaps between Vernier stimulus elements on sweep visual evoked potential measurements of human cortical Vernier responses
The present paper focuses on a classic hyperacuity, Vernier acuity-the ability to discriminate breaks in the collinearity of lines or edges on the order of only arcseconds of visual angle. We measured steady-state sweep visual evoked potentials (sVEPs) in response to 6 Hz periodic breaks in collinearity (Vernier offsets) in horizontal squarewave gratings. Ve

2. Women mortality due to cancers of the breast and cervix of the uterus: temporal and spatial analysis. City of São Paulo, SP, Brazil, 1996 to 2006 / Mortalidade por câncer de mama e de colo de útero: análise temporal e espacial, município de São Paulo, 1996 a 2006
Introduction: Several studies have shown that effects of inequalities in the mortality profiles and in different social groups are associated with social, cultural and economic factors. The analysis of the mortality due to breast cancer and cervix in women living in São Paulo, by local of residence, permitted to estimate the risk of dying from these cancers

3. Medidas de dependência local para séries temporais / Local dependence measures for time series
Diferente das medidas de associação global (coeficiente de correlação linear de Pearson, de Spearman, tau de Kendall, por exemplo), as medidas de dependência local descrevem o comportamento da dependência localmente em diferentes regiões. Nesta tese, as medidas de dependência local para variáveis aleatórias propostas por Bairamov et al. (2003), Bje

4. Medidas de assimetria bivariada e dependência local. / Measures of bivariate asymmetry and local dependence.
Esta tese trata de dois assuntos importantes na teoria de risco: o fenômeno da dependência local e a identificação e mensuração de assimetrias apresentadas pelos dados. A primeira parte trata de dependência local, sendo abordadas algumas medidas já analisadas na literatura. Versões locais dos coeficientes de Kendall e Spearman , baseadas na distribu

5. Estimação de contrastes de médias de tratamentos, de um experimento em blocos ao acaso, utilizando as análises clássica e espacial / Estimation of treatments means contrasts, in a random blocks model, using the classical and spatial analysis
Not controllable factors is common occur in experiments, they are responsible for the heterogeneity among parcels. Even executing the three experimentation basic principles in the design (repetition, randomization and local control), even so, may have correlation in errors and, therefore, spatial dependence in the area of study. If that autocorrelation struc

6. Friend or foe? Ecological Modernisation in Brazil
Ecological modernisation (EM) is a theory that proposes participation in decisionmaking, trust in science and technology, and preference for preventative measures, as strategies to simultaneously achieve environmental and economic objectives. The main objective of this thesis is to empirically assess the feasibility of EM in Brazil. This assessment is based

7. Calcium entry into voltage-clamped presynaptic terminals of squid.
Voltage-clamp measurements of Ca current and Arsenazo III measurements of intracellular Ca concentration were used to assess Ca ion entry into voltage-clamped presynaptic terminals of squid 'giant' synapses. Depolarization of voltage-clamped terminals filled with Arsenazo III produced absorbance changes consistent with intracellular accumulation of Ca ions.
