1. Estimation of precompression stress in an Ultisol cultivated with sugarcane
RESUMO Propriedades compressivas do solo são frequentemente utilizadas para entender o processo de compactação. Alternativamente a ensaios laboratoriais, funções de pedo-transferência têm sido usadas para estimar o comportamento mecânico em função de parâmetros físicos do solo. Este trabalho objetivou examinar o impacto da densidade (BD) e do con

2. Surface Spectroscopy of Oxisols, Entisols and Inceptisol and Relationships with Selected Soil Properties
ABSTRACT: Traditional method of soil survey is expensive, slow, and must be carried out by experienced researchers. Thus, advances in soil observation technologies and the need to obtain information quickly by modern techniques have intensified the use of proximal sensing. This study characterized surface reflectance spectra (A horizon) and related them to t

3. SHORTEST PATHS ON DYNAMIC GRAPHS: A SURVEY
ABSTRACT This paper provides an overview of the state-of-the art and the current research trends concerning shortest paths problem on dynamic graphs. The discussion is divided in two main topics: reoptimization and time-dependent shortest paths. Reoptimization consists in the solution of a sequence of shortest path problems in which each instance slightly di

4. "Salvar a la generación perdida": gubernamentalidad, empleabilidad y cultura del trabajo. El caso de un programa de empleo para jóvenes en Argentina
The aim of this article is to analyze how political and institutional logics associated with management and production of youth employment, work. We assume that these government interventions are designed attending mainly to employability and, moreover, they contribute to shape work culture. We analyze the case of a youth employment policy named Programa Jó

5. Estudo morfológico e hidroquímico de pequenas depressões na Nhecolândia, Pantanal, MS / Morphological and hydrochemical study of small depressions in Nhecolândia, Pantanal, MS
The southern part of the Taquari alluvial fan, called Nhecolândia, is a sub-region of the Pantanal of Mato-Grosso exhibiting a complex of round shape lakes, draining fields, forested sandy areas, small watercourses and small depressions. Former studies have shown that the sub-superficial water fluxes depend on the intensity of the flood and on the presence

6. Estratégias com garantia de estabilidade para a integração de controle preditivo e otimização em tempo real. / Strategies with guarantee of stability for the integration of model predictive control and real time optimization
The aim of this Thesis is the development of predictive controllers (MPC) with guarantee of stability and that are part of a control structure where Real Time Optimization (RTO) is present and produces optimizing targets for the predictive controller. The approaches of two and three-layer are considered. Three different strategies are presented: the first st

7. A estrutura e composição de comunidades microbianas (Bacteria e Archaea) em fragmentos de carvão pirogênico de Terra Preta de Índio da Amazônia Central / Structure and composition of bacterial communities (Bacteria and Archaea) in fragments of pyrogenic charcoal from Amazonian Dark Earth in the Central Amazon
Amazonian Dark Earth (ADE), also known as Terra Preta de Índio, present tropical A horizon, high pH, important nutrients for plant growth, high pyrogenic charcoal levels and intense biological activity when compared to its soil of origin. Soil microbial community is essential for ecosystem function, which is involved in fundamental processes such as the dec

8. Spline Dynamic Matrix Controller : uma nova formulação de controladores preditivos lineares
In the field of dynamic simulation, an understanding of the dynamic behavior of chemical processes is important from both process design and process system perspectives. Several methodologies have been developed so far, such as Step Response (SR), Transfer Function (TF) and Discrete State Space representation (DSS). Such approaches, however, have some disadv

9. Indicadores de sustentabilidade como ferramenta de apoio a gestão pública de resíduos da construção civil em municípios de pequeno porte / Sustainability indicators as assessment tool to support the RCC management in small cities
Introduction: In spite of Resolution No. 307/2002 requirements for the development of an Integrated Management Plan for Construction and Demolition Waste (C&D), in all Brazilian municipalities, few have it done. And, when developed, many are designed with a short time horizon and with purely corrective function, or are adaptations of experiences from other c

10. ONTOLOGIA MARXISTA E EDUCAÇÃO FÍSICA ESCOLAR: contribuições para o debate. / ONTOLOGY AND MARXIST SCHOOL PHYSICAL EDUCATION: contributions to the debate.
This research report aims at analyzing which ontological trends are subjacent to the pedagogical theories and propositions of School Physical Education. The dialectic historical materialism is our basis, as we understand that the immanent categorical complex to these philosophy and theory of knowledge allows us to radically comprehend our case study. Our emp

The economic and institutional space that involves the health sector has been go through deep transformations in Brazil, lazily following the tendency of developed countries, in cultural and historic conditions and, thus, structural specifics enough. In Brazil, the health sector adjustment ways are on their earlier stages of conception and application. The u
