1. Large-Scale Analysis and Modeling for Indoor Propagation at 10 GHz
Abstract It is essential to establish dominant propagation mechanisms in indoor environments to model propagation loss for 5th generation networks. This work presents, discusses and analyzes the data of measurement campaigns carried out in the 10 GHz band. These data were obtained in two different scenarios: a corridor and a laboratory. The measurement campa

2. Richness and large-scale distribution of marine benthic caridean shrimps (Decapoda: Caridea) from the Eastern Tropical Pacific
Abstract Based on an updated checklist of the benthic caridean shrimp fauna of the Eastern Tropical Pacific (ETP), we analyzed their large-scale species richness distribution patterns using a grid approximation. Caridean fauna is composed of 183 species belonging to 67 genera and 18 families. Alpheidae, Palaemonidae and Thoridae contributed largely to specie

3. Evidence of morphometric differentiation among Antarctic moss populations as a response to local microenvironment
ABSTRACTStudies on phenotypic variation among populations growing in different microenvironments may provide information about plasticity related to environmental pressures, and thus help to elucidate the potential evolutionary forces contributing to the origin and maintenance of diversity in any region. In this study we investigate morphometric variation on

4. Large scale distribution of bacterial communities in the upper Paraná River floodplain
A bacterial community has a central role in nutrient cycle in aquatic habitats. Therefore, it is important to analyze how this community is distributed throughout different locations. Thirty-six different sites in the upper Paraná River floodplain were surveyed to determine the influence of environmental variable in bacterial community composition. The site

5. Oceanografia e Química: unindo conhecimentos em prol dos oceanos e da sociedade
The marine environment is certainly one of the most complex systems to study, not only because of the challenges posed by the nature of the waters, but especially due to the interactions of physical, chemical and biological processes that control the cycles of the elements. Together with analytical chemists, oceanographers have been making a great effort in

6. Formação e evolução de galáxias: populações estelares na Via Láctea, galáxias elípticas e propriedades de galáxias em grupos / Galaxy Formation and Evolution: From the Milky Way to Galaxies in Groups
Understanding the way galaxies form and evolve throughout the cosmic time remains one of the greatest challenges of modern cosmology. Several processes are known to play a role in the formation of galaxies, such as feedback from supernovae and active galactic nuclei, chemical and dynamical evolution and environmental effects. This thesis encompasses these pr

7. Implementações sequencial e paralela de um novo algoritmo para a simulação de elementos e compostos magnéticos
The magnetic phenomena are widely used in many devices, such as electronic, data storage and telecommunications devices. The understanding of this phenomenon is therefore of great interest to support the improvement and development of new technologies. To better understand the magnetic phenomena, it is essential to study interactions at nano scale. When magn

8. Real-time path planning in large dynamic environments based on a Voronoi diagram / Planejamento de caminho em grandes ambientes em tempo real baseado no diagrama de voronoi dinâmico
Planejamento de caminho é a habilidade de encontrar um caminho livre de obst áculos a partir de uma posição inicial arbitrária até uma posição nal dada. Uma limitação no momento de procurar este caminho, é o tamanho do ambiente onde a busca é realizada. Grandes ambientes aumentam o tempo computacional de algoritmos para um nível indesejado. Nest

9. Modelagem de processo de negócio no apoio ao desenvolvimento ágil de software
This work describes a procedure for drawing up user stories based on architecture of business modeling; the objective is to help the implementation of complex systems (large-scale, realtimeor SAP) in environments with great propensity to changes, by the union of iterativebusiness modeling and concepts of agile software development. The characterization of th

10. How specialists can be generalists: resolving the "parasite paradox" and implications for emerging infectious disease
The parasite paradox arises from the dual observations that parasites (broadly construed, including phytophagous insects) are resource specialists with restricted host ranges, and yet shifts onto relatively unrelated hosts are common in the phylogenetic diversification of parasite lineages and directly observable in ecological time. We synthesize the emergin

11. Constituintes químicos e efeito ecotoxicológico do óleo volátil de folhas de Eucalyptus urograndis (Mirtaceae)
The volatile oil from the leaves of E. urograndis was analyzed by GC and GC-MS. It was identified 10 compounds in which, orto-cimene (41.4%) and 1,8-cineol (25.8%) were the main constituents. The induction of deleterious effect to aquatic organisms due to the presence of volatile oil lixiviated from E. urograndis leaves was studied using Daphnia laevis and D

12. Small dams and hydrological sustainability in the large-scale watersheds of the semi-arid environment: case of the OrÃs watershed, CearÃ, Brazil / Pequena aÃudagem e sustentabilidade hidrolÃgica em grandes bacias semi-Ãridas: estudo de caso da bacia do aÃude OrÃs
Um dos desafios centrais de investigadores e gestores de Ãgua em grandes bacias à avaliar, de modo confiÃvel, a disponibilidade de Ãgua em condiÃÃes reais. Em bacias do semi-Ãrido brasileiro, um dos principais desafios consiste em considerar os efeitos da proliferaÃÃo de pequenos aÃudes. Esta pesquisa tem como objetivo principal definir um arranjo
