1. Estimativa numérica de quantidades: um estudo de comparação entre crianças e adultos
Resumo O estudo acerca da estimativa numérica é pouco realizado no Brasil, embora já apresente considerável trajetória na literatura internacional. Entretanto, grande parte desses estudos estão relacionados à habilidade de realizar estimativas em crianças, desconsiderando qual seria o mais alto estágio de desenvolvimento desta habilidade, comparando

2. Perception of teachers and Ph.D. Programs graduate engineering university of San Carlos on indicators of scientific production / Percepção dos docentes e doutorandos dos programas de pós-graduação em engenharia da Universidade Federal de São Carlos sobre indicadores de produção científica
Os estudos sobre Ciência, Tecnologia e Sociedade apresentam‐se como uma análise crítica e interdisciplinar da Ciência e da Tecnologia num contexto social, com o objetivo de compreender os aspectos gerais do fenômeno científico‐tecnológico. Desta maneira, uma das áreas na qual seu desenvolvimento influencia diretamente a sociedade é a Eng

3. Voltage unbalace numerical evaluation and minimization:estimation by incremental sensitivity analysis and analytical solutions / Avaliação e minimização numérica do desequilíbrio de tensão : estimativa por análise de sensibilidade incremental e soluções analíticas
Voltage unbalance is one of the parameters analysed in power quality studies, representing the difference between the magnitudes of the voltages of a tri-phase electrical system, and the phase shift between these. It is desirable to have sinusoidal voltages with identical magnitudes and 120 electrical degrees phase shift between them, but in practice, there

4. The effect of performing corrections on reported uterine cancer mortality data in the city of São Paulo
Reports of uterine cancer deaths that do not specify the subsite of the tumor threaten the quality of the epidemiologic appraisal of corpus and cervix uteri cancer mortality. The present study assessed the impact of correcting the estimated corpus and cervix uteri cancer mortality in the city of São Paulo, Brazil. The epidemiologic assessment of death rates

5. Balanço de radiação, energia e fluxo de CO2 em ecossistema de manguezal na Amazônia / Radiation and energy balance and fluxes of CO2 in a Amazon mangrove ecosystem
This work use the longest series of continuous meteorological data and fluxes measurements of CO2, sensible heat and latent heat made in Amazon mangrove ecosystem. The series used in this study corresponds to the period of November, 2002 to August, 2003. The meteorological data were collected using an EDISOL system based on the hedí covariance technique. Th

6. A preferência pela prática de atividades físicas e esportivas: uma abordagem psicofísica / The preference for the practice of physical and sporting activities: an psychophysical analysis
A preferência pela prática de atividades físicas e esportivas é um atributo subjetivo de difícil mensuração e que tem sido um dos critérios fundamentais, na escolha e na decisão para a sua prática, nos dias atuais. Deste modo, a preferência pela prática de atividades físicas e esportivas foi investigada por meio de métodos psicofísicos escalar

7. Estimation of additive direct and maternal genetic and non additive effects and prediction of the performance of weights, scrotal circumference and muscling scores in a Bos taurus x Bos indicus, composite beef cattle population. / Estimação de efeitos genéticos aditivos diretos e maternos e não aditivos e, predição do desempenho de pesos, perímetro escrotal e musculosidade em uma população de bovinos de corte compostos (Bos taurus x Bos indicus)
Data of weights at birth, weaning, 390 days, weight gain from weaning to 390 days, scrotal circumference and muscling scores at 390 days of age of a population used in the formation of the Montana Tropical® beef composite, raised under tropical conditions, were analyzed under three different models to: i) determine genetic and environment effects ii) determ

8. EXTREME VALUE THEORY: A CONDITIONAL APPROACH FOR VALUE AT RISK ESTIMATION IN THE BRAZILIAN STOCK MARKET / A TEORIA DOS VALORES EXTREMOS: UMA ABORDAGEM CONDICIONAL PARA A ESTIMAÇÃO DE VALOR EM RISCO NO MERCADO ACIONÁRIO BRASILEIRO
The existence of fat tails is one of the striking stylized facts of financial returns distribution. This fact makes the use of traditional parametric models for Value at Risk (VaR) stimulation unsuitable for the estimation of low probability events (1% or less). This is because traditional models are based on the conditional normality assumption for financia

9. Estimation of Average Heterozygosity and Genetic Distance from a Small Number of Individuals
The magnitudes of the systematic biases involved in sample heterozygosity and sample genetic distances are evaluated, and formulae for obtaining unbiased estimates of average heterozygosity and genetic distance are developed. It is also shown that the number of individuals to be used for estimating average heterozygosity can be very small if a large number o

10. Yields of Soviet underground nuclear explosions at Novaya Zemlya, 1964-1976, from seismic body and surface waves
Surface and body wave magnitudes are determined for 15 U.S.S.R. underground nuclear weapons tests conducted at Novaya Zemlya between 1964 and 1976 and are used to estimate yields. These events include the largest underground explosions detonated by the Soviet Union. A histogram of body wave magnitude (mb) values indicates a clustering of explosions at a few

11. Derivation and Evaluation of a Labeled Hedonic Scale
The objective of this study was to develop a semantically labeled hedonic scale (LHS) that would yield ratio-level data on the magnitude of liking/disliking of sensation equivalent to that produced by magnitude estimation (ME). The LHS was constructed by having 49 subjects who were trained in ME rate the semantic magnitudes of 10 common hedonic descriptors w

12. Measuring kinetics of complex single ion channel data using mean-variance histograms.
The measurement of single ion channel kinetics is difficult when those channels exhibit subconductance events. When the kinetics are fast, and when the current magnitudes are small, as is the case for Na+, Ca2+, and some K+ channels, these difficulties can lead to serious errors in the estimation of channel kinetics. I present here a method, based on the con
