1. 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

2. Caracterização batimétrica e fisicooceanográfica do canal de acesso ao porto de Cabedelo/PB: uma análise ambiental ao derrame de óleo
The State of Paraíba is one of the most dynamic states of Brazil, strategically located in the northeast, is notable for the excellent potential for integration of different transportation modes forming the states of Rio Grande do Norte, Pernambuco and Alagoas. The dynamic that occurs with port activity causes changes in the space where it is installed. And

3. Avaliação comparativa entre técnicas de programação defensiva aplicadas a um sistema crítico simulado. / Comparative evaluation among defensive programming techniques applied in a critical system simulated.
The introduction of software systems for critical applications raises safety issues that have long fell predominantly on the development of the hardware composing such systems. Currently, standards related to safety software qualitatively assess the impact of their use on systems sensitive to random errors. The research developed here seeks, in addition to o

4. Simbologia cartográfica para biodiversidade: situação e critérios para elaboração
Due to the importance of biological diversity, several measures for its conservation and sustainable use are being developed worldwide. In Brazil, some examples of these measures are the Program of Research in Biodiversity (PPBio) and the Brazilian Program of Bioprospecting and Sustainable Development of Biodiversity Products (PROBE). Parallel to these progr

5. ExpressÃo de cinco diferentes proteÃnas de interesse farmacolÃgico em sementes transgÃnicas de soja [Glycine Max L. (Merril)]
Superior plants represent a convenient system for large-scale production of heterologous proteins. Its potential has been confirmed by the commercial success of such production systems, based on genetic transformation of a broad range of vegetable species, resulting in efficient production of more than 100 different heterologous proteins. A representative pe

6. Albedo of an Amazon tropical rainforest: field measurements, remote sensing, modeling, and its influence on the regional climate / Albedo de uma floresta tropical Amazônica: medições de campo, sensoriamento remoto, modelagem, e sua influência no clima regional
Albedo is defined as a ratio between reflected solar radiation and incoming solar radiation over a surface. It is a main factor that affects the terrestrial radiation balance and has been frequently considered in the global and regional climate studies. Amazon is one of planets regions where the response of regional atmospheric circulation is more intense. S

7. Contribuição ao estudo de controle plantwinde: controle indireto e coordenação de controladores descentralizados.
The design of plantwide control systems has received increasing attention in the last years. The modern chemical plants usually consist of hundreds of interconnected elementary processes and unit operations (large scale complex systems). These plants are usually characterized and dominated by large and highly integrated and automatized installations, with se

8. Turbulent shallow-water model for orographic subgrid-scale perturbations
A parallel pseudo-spectral method for the simulation in distributed memory computers of the shallow-water equations in primitive form was developed and used on the study of turbulent shallow-waters LES models for orographic subgrid-scale perturbations. The main characteristics of the code are: momentum equations integrated in time using an accurate pseudo-sp

9. Sistemas hierarquicos multiniveis em automação e controle
Large-scale systems are often characterized by hierarchical structures, and they usually have multiple objectives that may be conflicting. The modelling of large-scale systems is normally a dificult task and of using the theory of integrated, hierarchical large-scale multilevel complex solution. This study system analysis methodology, aims at providing an sy

10. Informatics Resources to Support Health Care Quality Improvement in the Veterans Health Administration
Information systems are increasingly important for measuring and improving health care quality. A number of integrated health care delivery systems use advanced information systems and integrated decision support to carry out quality assurance activities, but none as large as the Veterans Health Administration (VHA). The VHA's Quality Enhancement Research In

11. Analysis of Post-transcriptional Regulations by a Functional, Integrated, and Quantitative Method*
In the past 10 years, transcriptome and proteome analyses have provided valuable data on global gene expression and cell functional networks. However, when integrated, these analyses revealed partial correlations between mRNA expression levels and protein abundance thus suggesting that post-transcriptional regulations may be in part responsible for this disc

12. Evolution of vertebrate steroid receptors from an ancestral estrogen receptor by ligand exploitation and serial genome expansions
The evolution of novelty in tightly integrated biological systems, such as hormones and their receptors, seems to challenge the theory of natural selection: it has not been clear how a new function for any one part (such as a ligand) can be selected for unless the other members of the system (e.g., a receptor) are already present. Here I show—based on
