1. Root parasitism by Scybalium fungiforme Schott & Endl. is not random among host species in seasonal tropical forest
ABSTRACT Though they comprise 1 % of plant species on the planet, plant parasites are poorly known. They have been considered a threat to cultivated plants and to the conservation of host species in natural areas. Due to the complex interactions they have with their hosts, understanding their biology is fundamental to the development of conservation strategi

2. Rotatividade docente na rede municipal de ensino do Rio de Janeiro
Resumo O estudo tem como objetivo investigar as dinâmicas de rotatividade docente na rede municipal de ensino do Rio de Janeiro. Tem-se como pressuposto a existência de padrões não aleatórios de distribuição de professores entre escolas, destacando-se possíveis convergências entre perfis de professores e alunos, principalmente no que diz respeito a

4. Exploratory and confirmatory factorial analysis of the OHIP-Edent instrument
Abstract Several instruments have been used to measure oral health-related quality of life (OHRQoL). The Oral Health Impact Profile (OHIP) questionnaire was based on the concept that sequential events related to oral diseases can cause discomfort, functional limitations and consequently, result in dysfunctions and even disabilities. There are few studies in

5. Searching for convergent evolution in manganese superoxidase dismutase using hydrophobic cluster analysis
There are numerous examples of convergent evolution in nature. Major ecological adaptations such as flight, loss of limbs in vertebrates, pesticide resistance, adaptation to a parasitic way of life, etc., have all evolved more than once, as seen by their analogous functions in separate taxa. But what about protein evolution? Does the environment have a stron

6. Globalización, cambios en la estructura de poder y nuevas elites empresariales: una mirada comparada de Uruguay
The paper wondering about trends and challenges: Which are the main causes of challenges and reproduction of business elites? What are the patterns of Latin-American business elites? What are the consequences on economical recruitment because of neoliberal economic globalization? Which are the main theoretical and comparative explanations? The comparative me

7. Estimação e previsão da estrutura a termo das taxas de juros usando técnicas de inteligência computacional / Term structure of interest rate modeling and forecasting using computational intelligence techniques
This work proposes the term structure of interest rates modeling and forecasting using computational intelligence techniques, based on data from the US and Brazilian fixed income markets. The yield curve modeling includes the use of some evolutionary computation methods like Genetic Algorithms, Differential Evolution and Evolution Strategies in comparison wi

8. Generalized linear differential equations in a Banach space: continuous dependence on parameters and applications / Equações diferenciais generalizadas lineares em espaços de Banach: dependência contínua com relação a parâmetros e aplicações
The purpose of this work is to investigate continuous dependence on parameters for generalized linear differential equations in a Banach space- valued setting. More precisely, we establish a theorem inspired by the clas- sical continuous dependence result due to Z. Opial. In addition, our second outcome extends, to Banach spaces, the result proved by M. Asho

9. Mínimos locais de funcionais com dependência especial via Γconvergência: com e sem vínculo
Na primeira parte deste trabalho, abordamos a existência de soluções estacioná-rias estáveis para uma classe de equações de reação-difusão com dependência espacial em domínios limitados 2 e 3-dimensionais. Esta abordagem foi feita via existência de mínimos locais dos funcionais de energia correspondentes. Para tal, foi suficiente encontrar cond

10. Anatomia ecolÃgica foliar de espÃcies da caatinga / Leaf anatomy of species of ecological caatinga
In semiarid environments water availability is a main limiting factor for plants. A combination of characteristics can contribute to saving water, including the anatomical ones. The anatomical attributes often associated with environments of water restriction are called xeromorphic. The leaves are organs commonly exposed to sunlight which have large areas of

11. Filtros de Kalman robustos para sistemas dinâmicos singulares em tempo discreto / Robust Kalman filters for discrete-time singular systems
This thesis considers the optimal robust estimates problem for discrete-time singular dymanic systems. New recursive algorithms are developed for the Kalman filtered and predicted estimated recursions with the corresponding Riccati equations. The singular robust Kalman type filter and the corresponding recursive Riccati equation arer obtained in their most g

12. Recursive robust regulator for discrete-time state-space systems / Regulador robusto recursivo para sistemas lineares de tempo discreto no espaço de estado
This dissertation deals with robust recursive regulators for discrete-time systems subject to parametric uncertainties. A new quadratic functional based on the combination of penalty functions and game theory is proposed to solve this class of problems. An important issue of this approach is that the recursiveness can be performed without the need of adjusti
