SEIS CENTÍMETROS: UMA ANALÍSE ANTROPOMÉTRICA DA POF 2002- 2003

This paper analyzes the heights of the Brazilian people using anthropometric and economic data from the Pesquisa de Orçamentos Familiares (POF) 2002-2003. The literature suggests that height is a good proxy of the physical life conditions of the populations. The tabulations of POF microdata indicate that the difference among the heights of 21 and 65-year-old men is circa 6 centimeters. The same value, by chance, represents the difference on the stature of the poorest and richest quintiles. There are also steady regional differences; in the North and Northeast, the heights are about 2 centimeters lower than the national average, for any cohort. Regression analyses show that proxy variables related to life conditions during body growth and regional dummies were statistically significant causes of the variation on the height of individuals. In contrast, color, urban/rural and inequality variables were not significant. The results replicate what the historiography on life conditions and stature says: the social environment has a significant impact on the average height of the populations.

Growth and inequalities of height in Brazil (1939-1981)

This paper analyzes the heights of Brazilian people using anthropometric and economic data. The literature suggests that height is a good proxy of the material living conditions of different populations. Data indicate that the difference between the heights of 21 and 65-year-old men is approximately six centimetres. The same value, by coincidence, represents the difference in the stature of the poorest and richest quintiles. Adjusted data show an increase of 3.8 centimetres in the heights of adult male Brazilians born between 1939 and 1981. There are also stable regional differences; in the North and Northeast of the country, heights are about two centimetres lower than the national average for all groups. Regression analyses show that proxy variables related to living conditions during bodily growth, and using regional dummies, were statistically significant causes of the variation in the heights of individuals. In contrast, colour, urban/rural, and inequality variables were not significant. The results replicate what the historiography of the relation between living conditions and stature makes clear: the social environment has a significant impact on the average height of populations

Pegada hídrica da produção de cana-de-açúcar no Paraná de 2010 a 2020.

O objetivo deste trabalho foi estimar as pegadas hídricas verde, azul e cinza da cana-de-açúcar, nas principais mesorregiões produtoras do Paraná, de 2010 a 2020. A metodologia utilizada foi proposta por Hoekstra et al. (2011), com adaptações necessárias para a realidade local. A mesorregião Noroeste Paranaense exibiu os maiores valores para a pegada verde (179,05 m³ Mg-1, em 2010, e 200,26 m³ Mg-1, em 2020). Norte Central e Noroeste Paranaense foram as mesorregiões com os maiores valores médios de pegada azul (47,43 m³ Mg-1 e 46,66 m³ Mg-1, respectivamente). O Noroeste Paranaense apresentou também a maior pegada hídrica cinza, com 12,33 m³ Mg-1, em 2010, e 13,79 m³ Mg-1, em 2020. A mesorregião de maior pegada hídrica média no período foi o Noroeste Paranaense, com 249,3 m³ Mg-1, e a menor pegada média foi a do Norte Pioneiro Paranaense, com 179,35 m³ Mg-1. A média da pegada hídrica total da produção de cana-de-açúcar das mesorregiões paranaenses foi de 206,63 m³ Mg-1

UMA ANÁLISE ECONOMÉTRICA DO FUTEBOL BRASILEIRO

This paper reports regression results identifying the variables influencing a state's performance in Brazilian Soccer's Championship. The results reveal that economic, club-specific controls and political factors are important. An inverted U-shaped relationship is found with respect to regional per capita wealth. We also found significant positive political effects with respect to the performance of Brazilian teams in the short run and negative in the long run. Explanations for our results are offered.Neste artigo apresentamos uma análise "esportométrica" do desempenho dos times de futebol participantes de um dos mais importantes torneios do gênero no mundo: o Campeonato Brasileiro (1971-1998). Postula-se que o bom desempenho dos times seja relacionado não apenas à qualidade de seus jogadores como também a fatores econômicos e políticos. Duas classes de modelos principais são estimados sob definições alternativas da variável dependente ("sucesso do time no campeonato"): pooled logit model e fixed effects logit model Os resultados mostram que a chance de se estar nos primeiros lugares do ranking do campeonato apresenta uma relação positiva com respeito à eficiência do time em termos de artilharia. Além disso, estados mais ricos possuem maior chance de apresentar times nas primeiras colocações do campeonato, embora este efeito seja decrescente. Finalmente, existem evidências de que, pelo menos no curto prazo, a política exerce influência positiva sobre os resultados estaduais obtidos no Campeonato Brasileiro de Futebol. Além disso, os resultados sugerem que no longo prazo o processo político reduz a chance de o estado colocar uma equipe entre as melhores do campeonato brasileiro de futebol

Evolutionary continuous cellular automaton for the simulation of wet etching of quartz

Anisotropic wet chemical etching of quartz is a bulk micromachining process for the fabrication of micro-electro-mechanical systems (MEMS), such as resonators and temperature sensors. Despite the success of the continuous cellular automaton for the simulation of wet etching of silicon, the simulation of the same process for quartz has received little attention-especially from an atomistic perspective-resulting in a lack of accurate modeling tools. This paper analyzes the crystallographic structure of the main surface orientations of quartz and proposes a novel classification of the surface atoms as well as an evolutionary algorithm to determine suitable values for the corresponding atomistic removal rates. Not only does the presented evolutionary continuous cellular automaton reproduce the correct macroscopic etch rate distribution for quartz hemispheres, but it is also capable of performing fast and accurate 3D simulations of MEMS structures. This is shown by several comparisons between simulated and experimental results and, in particular, by a detailed, quantitative comparison for an extensive collection of trench profiles. © 2012 IOP Publishing Ltd.We are grateful to D Cheng and K Sato (Nagoya University, Japan) for providing part of the experimental data.

Magnetic Particle-Scanning for Ultrasensitive Immunodetection On-Chip

We describe the concept of magnetic particle-scanning for on-chip detection of biomolecules: a magnetic particle, carrying a low number of antigens (Ag's) (down to a single molecule), is transported by hydrodynamic forces and is subjected to successive stochastic reorientations in an engineered magnetic energy landscape. The latter consists of a pattern of substrate-bound small magnetic particles that are functionalized with antibodies (Ab's). Subsequationuent counting of the captured Ag-carrying particles provides the detection signal. The magnetic particle-scanning principle is investigated in a custom-built magneto-microfluidic chip and theoretically described by a random walk-based model, in which the trajectory of the contact point between an Ag-carrying particle and the small magnetic particle pattern is described by stochastic moves over the surface of the mobile particle, until this point coincides with the position of an Ag, resulting in the binding of the particle. This model explains the particular behavior of previously reported experimental dose-response curves obtained for two different ligand-receptor systems (biotin/streptavidin and TNF-alpha) over a wide range of concentrations. Our model shows that magnetic particle-scanning results in a very high probability of irrununocomplex formation for very low Ag concentrations, leading to an extremely low limit of detection, down to the single molecule-per-particle level. When compared to other types of magnetic particle-based surface coverage assays, our strategy was found to offer a wider dynamic range (>8 orders of magnitude), as the system does not saturate for concentrations as high as 10(11) Ag molecules in a 5 mu L drop. Furthermore, by emphasizing the importance of maximizing the encounter probability between the Ag and the Ab to improve sensitivity, our model also contributes to explaining the behavior of other particle-based heterogeneous immunoassays
