1. Pyrite utilization in the carboniferous region of Santa Catarina, Brazil - Potentials, challenges, and environmental advantages
Abstract The main coal seams explored in the coal region of Santa Catarina are Barro Branco (BB) and Bonito (BO). Owing to the association with the mineral matter, the tailings generated in the beneficiation are arranged in disposal areas, and subject to the generation of acid mine drainage (AMD). The objective of this study was to evaluate the use of pyrite

2. Scale of operation, allocative inefficiencies and separability of inputs and outputs in agricultural research
In this article we consider some properties of concern for research production at Embrapa. We apply statistical tests to address questions related to the scale of operation, the presence of allocative inefficiencies and separability of inputs and outputs. The production process is assessed by nonparametric methods with the use of Data Envelopment Analysis. T

3. Caracterização e separabilidade de agregados miúdos produzidos a partir de resíduos de construção e demolição. / Technological characterization and separability studies on fine aggregates produced from construction and demolition waste.
The current demand for recycling on construction is due to the increasing consumption of aggregates, the exhaustion of deposits close to large cities as well as the ban on inert materials dumping in landfills and the rising cost of its disposal. Moreover, with the remarkable increasing on construction activities in many countries, the management of Construct

4. Estudo da influência dos particulados no fenômeno de agregação dos asfaltenos por espectrometria de varredura óptica
The processing of national petroleums causes many operational problems due to the asphaltene aggregation phenomena. To evaluate the behavior of these phenomena, a study based on optical scan technique was carried out to understand the behavior of pure oils and their mixtures. The evaluation according to criteria established by ASTM D7061-06¹ gives a result

5. Matéria, alma e identidade pessoal em Hume
I defend, in this dissertation, a materialist interpretation of humean philosophy. This interpretation is based on some of the themes presented in Book 1 of the Treatise of Human Nature. The task is divided in three parts: in the first chapter, I examine two of the principles which ground the theory of ideas presented in Part 1, the principles of copy and of

6. The Private Memory of Aggregate Shocks
We study constrained efficient aggregate risk sharing and its consequence for the behavior of macro-aggregates in a dynamic Mirrlees’s (1971) setting. Privately observed idiosyncratic productivity shocks are assumed to be independent of i.i.d. publicly observed aggregate shocks. Yet, private allocations display memory with respect to past aggregate shocks,

7. Testes estatísticos em regressão logística sob a condição de separabilidade / Statistical tests in logistic regression under separability condition
Logistic regression is the statistical method of analysis used when the objective is to verify the relationship between one dichotomic response variable and explicative variables of interest. Usually, the model parameters are estimated through the genuine maximum likelihood method, and tests about these parameters are built assuming approximated distribution

8. Separabilidade e distinção real entre corpo e alma nas Meditações Metafísicas
A presente dissertação investiga o argumento da distinção real entre corpo e alma presente nas Meditações Metafísicas. O objetivo central é explicar o motivo pelo qual, nesta obra, a separabilidade entre corpo e alma é posta como condição suficiente para esse tipo de distinção. Para isso, percorre, ao longo das Meditações, os conceitos de alma

9. Segmentação de imagens ultrassonográficas para detecção de nódulos / Segmentation of ultrasound images to detect nodules
Breast cancer is one of the main health problems of the female population and should be faced as an important public health care issue. The ultrasound scanning is considered the most effective in complementary method of breast diagnosis. Nevertheless, the acquisition format of this sort degrades the images in various ways, being the speckle noise of noticeab

10. Aprendizado de máquina baseado em separabilidade linear em sistema de classificação híbrido-nebuloso aplicado a problemas multiclasse
Este trabalho de mestrado descreve um sistema classificador inteligente aplicado a problemas multiclasse não-linearmente separáveis chamado Slicer. O sistema adota uma estratégia de aprendizado supervisionado de baixo custo computacional (avaliado em ) baseado em separabilidade linear. Durante o período de aprendizagem o sistema determina um conjunto de

11. Crop discrimination using harmonic analysis of EVI MODIS time-series data / Discriminação de culturas agrícolas utilizando análise harmônica de séries temporais de dados EVI-MODIS
In the present decade, agriculture has increased worldwide in importance due to sensitive matters such as the current food crisis, biofuels boom, and the land use and land cover changes from savanna/forest areas to agriculture expansion. As a consequence, crop monitoring at regional and national scales has become essential at different levels of knowledge an
