1. Discovery and characterization of SSR markers in Eugenia uniflora L. (Myrtaceae) using low coverage genome sequencing
Abstract: Eugenia uniflora L. (Myrtaceae) is a tree species widely distributed in South America suffering the effects of the exploitation of natural populations. In this study, we employed low coverage sequencing of the E. uniflora genome for mining of SSR markers. The de novo assembly generated 2,601 contigs with an average length of 1139 bp and spans 3.15

2. Identification of coffee WRKY transcription factor genes and expression in resistance responses to pathogens.
In plants, WRKY proteins are a group of transcription factors existing as a gene superfamily that play important roles in regulation of defense response pathways. To assess the diversity of this protein family in coffee (Coffea spp.), data mining methods were used on a set of around 200,000 coffee expressed sequence tags. A total of 53 different putative WRK

4. Técnicas de combinação para agrupamento centralizado e distribuído de dados / Ensemble techniques for centralized and distributed clustering
A grande quantidade de dados gerada em diversas áreas do conhecimento cria a necessidade do desenvolvimento de técnicas de mineração de dados cada vez mais eficientes e eficazes. Técnicas de agrupamento têm sido utilizadas com sucesso em várias áreas, especialmente naquelas em que não há conhecimento prévio sobre a organização dos dados. Contudo

5. Geração automática de código para a execução em um ambiente de computação em DataFlow
The computers architectures are becoming more distributed and hierarchical,that is, there exist lots of computers in a cluster and there are many processors in these computers and these processors have multiple cores. Many models have been proposed to explore the features of the computers architectures. The Data-flow computing models stand out among the prop

6. INTEGRAÇÃO DE REPOSITÓRIOS DE SISTEMAS DE BIBLIOTECAS DIGITAIS E SISTEMAS DE APRENDIZAGEM / INTEGRATION OF REPOSITORIES OF DIGITAL LIBRARY SYSTEMS AND LEARNING MANAGEMENT SYSTEMS
With the widespread use of Information Technology for teaching support, it is usual to made digital content available through Digital Library Systems (DLMS) or Learning Management Systems (LMS).These systems, however, work independently, have different characteristics and manipulate different types of materials, and their data and metadata repositories are h

7. Quality of life at work and organizational culture / Qualidade de vida no trabalho e cultura organizacional
The process of globalization has been considered by authors, such as Santos (2001) Hall (2001) and Bauman ( 2003), as a process of destruction in which cultural, political and geographic consequences have triggered paradoxical effects worldwide, specially, in third world countries and developing countries such as Brazil. Such effects are also seen in nationa

8. Estudo do modelo de computação orientada a serviços e sua aplicação a um sistema de mineração de dados
This work presents a study on the applicability and performance of Web Services as a materialization of Service Oriented Architectures (SOA), with a case study on a real service oriented system. In this concern, the major contribution was to show the steps necessary to design and build service oriented applications, discussing difficulties along the way and

9. Um método baseado em hipóteses estatísticas para a descoberta de itemsets com distribuição assimétrica em processos de mineração de dados.
Nowadays, the ability to make good decisions at the right moment is a very desirable characteristic. To assist in the process of decision making, various techniques have been created. These techniques, however, need useful and reliable information to be eective. Data mining is an essential step in knowledge discovery in databases, being thus very important t

10. AN MULTIAGENT FRAMEWORK FOR PERSONALIZATION OF THE WEB BASED ON MODELING OF USERS AND IN THE MINING OF USE / UM FRAMEWORK MULTIAGENTE PARA A PERSONALIZAÇÃO DA WEB BASEADO NA MODELAGEM DE USUÁRIOS E NA MINERAÇÃO DE USO
With the continuous migration of a great diversity of services to the Web, the need for characterizing the users in this environment increases. For that, components that can continually perceive their environment and rapidly adapt to its changes are required, thus reflecting the changes in the user behaviors. Among the existent approaches for modeling Web us

11. Estudo da remoção dos ions cromo(III) e cobre(II) em colunas de leito fixo pela alga marinha Sargassum sp
The increasing concern with the environment question and the severity of the legislation in discarding industrial and domestic effuents containing metals has motivated the search for new technologies of recovery and removal of metals. The metal removal with biomass of microorganisms has been investigated as an alternative to the traditional methods of metal

12. SPINE: an integrated tracking database and data mining approach for identifying feasible targets in high-throughput structural proteomics
High-throughput structural proteomics is expected to generate considerable amounts of data on the progress of structure determination for many proteins. For each protein this includes information about cloning, expression, purification, biophysical characterization and structure determination via NMR spectroscopy or X-ray crystallography. It will be ess
