1. Prediction of soil CO2 flux in sugarcane management systems using the Random Forest approach

ABSTRACT: The Random Forest algorithm is a data mining technique used for classifying attributes in order of importance to explain the variation in an attribute-target, as soil CO2 flux. This study aimed to identify prediction of soil CO2 flux variables in management systems of sugarcane through the machine-learning algorithm called Random Forest. Two differ

2. An Alert Regarding a Common Misinterpretation of the Van Genuchten α Parameter

ABSTRACT Among the equations available to describe the relation between matric potential and soil water content, the soil water retention function, the most commonly used is the equation proposed by Van Genuchten in his 1980 landmark paper. In soil physics literature, especially in Brazil, several authors relate the inverse of the Van Genuchten parameter α

3. Preparing the Terrain: Conditioning Factors for the Regionalization of the Vote for Federal Deputy in São Paulo

This article proposes a new interpretation of the regional distribution of votes in the dispute for legislative offices in Brazil. The literature has traditionally understood regionalization to be evidence that politicians deliberately create zones of influences in certain areas. We argue, however, that other dimensions of the Brazilian electoral system, not

4. The Hydrogen Cold Work Peak in BCC Iron: Revisited, with First Principles Calculations and Implications for Hydrogen Embrittlement

We examine experimental and theoretical results on the cold-work (Snoek-Köster) peak in bcc Fe due to H using density functional theory (DFT). We reaffirm that Seeger’s interpretation of the H cold-work peak (Hcwp), involving motion of H with kinks on non-screw dislocations associated with the intrinsic-dislocation α peak, has experimental backing. Use o

5. Freedom through form: Bolívar Lamounier and the Liberal Interpretation of Brazilian Political Thought*

This article examines the contribution of Bolívar Lamounier to Brazilian political thought. Our main argument is that, by replacing nationality with freedom as the defining criterion of the real, Bolívar Lamounier offers a liberal interpretation of Brazilian political thought, in direct contrast to the nationalist tradition formulated by Oliveira Vianna. I

6. Aproximación a la experiencia de personas viejasque viven solas en contextos precarios: Ciudad Bolívar, Bogotá-Colombia

Abstract This article presents the results of a qualitative approximation of the city conditions perceived by older adults in a precarious urban context of Bogotá-Colombia. For this approach, some domains of the “Age-friendly Cities” models, by the World Health Organization, were used, such as: habitation, habitability, transportation, community support

7. Geochemistry of basaltic flows from a basalt ring structure of the Serra Geral formation at Água Vermelha dam, Triângulo Mineiro, Brazil: implications for the magmatic evolution of the Paraná-Etendeka Province

ABSTRACT: The Serra Geral Formation belongs to the Paraná-Etendeka Magmatic Province (PEMP) and its geochemical and petrographic characteristics are not homogeneous. Many studies segment this group into six basaltic and two rhyolitic magma-types. It is believed that its extrusion occurred through crustal fissures in the Cretaceous, but some authors describe

Abstract In this article, the main findings of a study are presented which reveals and interprets the discourses and images about violence in school ambience in the newspapers of the city of La Plata in Argentina. We focus on the photographic narratives in the news coverage by El Día, Hoy, Extra, and Diagonales from the city of La Plata, between 1993 and 20

9. The Mato Perso Conduit System: evidence of silicic magma transport in the southern portion of the Paraná-Etendeka LIP, Brazil

ABSTRACT: The Mato Perso Conduit System is described from a ~ 120 km2 area in south Brazil exposing silicic volcanics of the Paraná-Etendeka LIP. A volcanic succession is defined by basaltic flows covered by flat-lying oxidized vitrophyres, banded vitrophyres cutting the lower lavas and grey flat-lying vitrophyres covering all the units. Flow morphologies d

ABSTRACT OBJECTIVE To estimate the prevalence of Burnout in a medium or long-stay hospital, to monitor its evolution and to highlight the importance of cut-off points used to avoid distortions in the interpretation of the results. METHODS Two cross-sectional studies (2013–2016) were carried out, applying the Spanish version of the Maslach Burnout Invento
