1. Louis de Broglie's wave-particle duality: from textbooks’ blackboxes to a chain of reference presentation
Abstract We discuss the proposition of wave-particle duality made by Louis de Broglie in the period of 1922-1924 as well as the narratives of undergraduate Physics textbooks that introduce this topic. After a brief discussion on the nature of scientific reality, we point out the main theories, assumptions and techniques adopted by de Broglie to achieve the r

2. Mecanismos de limitação da energia de raios cósmicos durante sua propagação
Resumo A cada segundo que passa, um número muito grande de partículas de origem cósmica atravessam o planeta. A maior parte delas pouco interage com a matéria e sua passagem não é percebida, exceto pelos pesquisadores da física de partículas. Os raios cósmicos são um tipo destas partículas, de origem extraterrestre, que podem ser estudados com aux

3. Desempenho de plantas de cobertura no controle da erosão hídrica no Sul de Minas Gerais / Performance of cover crops to control erosion in the South of Minas Gerais
The erosion initiates with the impact of the raindrop on the soil surface, causing the transport of sediment, nutrients and organic matter. To reduce this erosion, the use of conservation practices, such as proper management and planting of cover crops that reduce these losses, is essential. The objective of this study was to evaluate the potential of plant

4. Symbolism, the missing link: study of Science of Letters in sufism / Simbolismo, o elo perdido: estudo da Ciência das Letras no sufismo
In the modern occidental world, with rare exceptions that are located primarily in currents of Philosophy, Psychology, Mysticism and Physics, we face a confrontation between two opposite and apparently contradictory positions. On one side, the belief in a God which reigns the material world, but with whom this same world does not interact due to this Gods co

5. Vegetation and soil gradient in the restinga forest in Espirito Santo, Brazil / Gradiente vegetacional e pedológico em floresta de restinga no Espírito Santo, Brasil
The Restingas are ecosystems that occur in sandy soils deposited during the Quaternary. These are known to have a high diversity of vegetation, but few studies provide information on abiotic factors determining this diversity. This study aimed to: (i) assess the influence of the chemical aspects, physical soil and flooding in phytophysionomic determination,

6. Analysis of the characteristics of the wood and the candeia essential oil - Eremanthus erythropappus (DC.) Macleish, of the region of Aiuruoca, MG / Análise das características da madeira e do óleo essencial de candeia - Eremanthus erythropappus (DC.) Macleish, da região de Aiuruoca, MG.
Forests have been fundamental as a source of several basic necessities of the human being, as shelter, clothes, nourishment, energy etc. In this context, essential oils have had an important role, either in the national or in the international scene. Many forest species have the potential for oil extraction and, amongst these, candeia (Eremanthus erythroppap

7. SOIL PHYSICAL AND BIOLOGICAL CHARACTERIZATION AFTER HERBICIDES APPLICATION IN BLACK WATTLE (Acacia mearnsii De Wild.) STANDS IN RIO GRANDE DO SUL / CARACTERIZAÇÃO FÍSICA E BIOLÓGICA DO SOLO APÓS APLICAÇÃO DE HERBICIDAS EM PLANTIOS DE ACÁCIA-NEGRA (Acacia mearnsii De Wild.) NO RIO GRANDE DO SUL
The study of soil quality biological indicators in areas classified as forest production units is important to understand the ecological processes that occur in these systems. Monitoring the soil fauna in modified environments, when management practices involve chemical products in the environment, is an instrument that allows to evaluate not only the soil q

8. Estado fundamental e excitações coletivas de condensados de Bose-Einstein espinoriais / Ground state and collective excitations od spinor Bose-Einstein condensates
In the framework of the Bogoliubov theory, we determined the equilibrium configurations and the collective excitations of a homogeneous Bose-Einstein S = 1 spinor condensate, in the presence and absence of an externa1 magnetic field. In this thesis we found the equilibrium configurations as function of the parameters and m, where q is the intensity of the qu

9. Structural and dynamical properties of a quasi-onedimensional classical binary system / Estudo das propriedades estruturais e dinÃmicas de um sistema binÃrio quasi-unidimensional.
The aim of this work is to study the structural and dynamical properties of a classical binary system of charged particles confined in a two dimensional channel. Such a system is described in the literature as quasi-unidimensional, and its relevance is supported by the possibility of technological applications, shown recently in the scientific literature, an

10. Manejo de coberturas do solo e de plantas espontâneas em pomar orgânico de maçã. / Soil cover and weed management in na organic apple archard.
The demand for healthy and non-contaminated foods has increased between the consumers that become more and more exigent in terms of quality. The organic products appear as an option for the requirements of these consumers. However, research involving the organic production of fruits is still incipient. Thus, this study was carried out to evaluate the weed co

11. An euclidean approach as a method to study the Unruh effect / Uma estratégia euclidiana para o estudo do efeito Unruh
This paper proposes a Euclidean strategy to understand the Unruh effect. On that ground we first study it for free massless scalar fields the way it is usually presented to pliysicists, which is closer to Unruhs original work [32]. Then we infer the effect from an algebraic perspective. We study the proprieties and definitions of KklS states in order to unde

12. Avaliação da higienização do resíduo de caixa de areia de estações de tratamento de esgoto operadas pela CESAN
The process of treatment for wastewater produces solid waste that need to be constantly removed for to keep the treatments efficiency, amongst it, the waste deposited in the deep of the grit removal. The grit removal has the objective of to remove from wastewater the grit and others particulas, including the organics, presents in the wastewater in nature, th
