1. 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

2. Tratamento de condições especiais para busca por similaridade em bancos de dados complexos / Treatment of special conditional for similarity searching in complex data bases
A quantidade de dados complexos (imagens, vídeos, séries temporais e outros) tem crescido rapidamente. Dados complexos são adequados para serem recuperados por similaridade, o que significa definir consultas de acordo com um dado critério de similaridade. Além disso, dados complexos usualmente são associados com outras informações, geralmente de tipo

3. Planejamento de inibidores baseado em fragmentos moleculares para a enzima gliceraldeído-3-fosfato desidrogenase de Trypanosoma cruzi / Design of inhibitors through fragment-based drug discovery for the enzyme glyceraldehyde-3-phosphate dehydrogenase from Trypanosoma cruzi
Chagas disease is a parasitic illness endemic in Latin America caused by the trypanosomatid parasite Trypanosoma cruzi that spreads around the world due to people migration. Nowadays, Benznidazole and Nifurtimox (banned in Brazil), are used for the treatment of this disease but causes severe side effects to patients. Recently, three new molecules have reache

4. Soluções aproximadas para algoritmos escaláveis de mineração de dados em domínios de dados complexos usando GPGPU / On approximate solutions to scalable data mining algorithms for complex data problems using GPGPU
The increasing availability of data in diverse domains has created a necessity to develop techniques and methods to discover knowledge from huge volumes of complex data, motivating many research works in databases, data mining and information retrieval communities. Recent studies have suggested that searching in complex data is an interesting research field

5. HQ feature: descritores de forma utilizando a curva de Hilbert
A classificação e recuperação por similaridade baseadas em descritores de formas são processos de grande importância em tarefas de reconhecimento de padrões e recuperação de formas baseada em conteúdo. O desenvolvimento de descritores eficientes para caracterizar a forma ainda é um desafio. Este trabalho se concentra no desenvolvimento de novos ex

6. A TributaÃÃo como instrumento de regulaÃÃo econÃmico em PaÃses integrados
The taxation is essential for the achievement of the financier-economic politics of the States, a time that is to leave of this activity that is collected good part of the resources to be used in such politics. On the other hand, the taxation also can be used as instrument of regulation economic, capable to influence in the consumption, to stimulate the savi

7. Development of a database for classification and analysis of type IV secretion systems / Desenvolvimento de um banco de dados para classificação e análise de sistemas de secreção do tipo IV bacteriano
The type IV secretion system can be classified as a large family of macromolecule transporters divided in three recognized sub-families involved in different bacterial functions. The major sub-family of T4SS is the conjugation system, which allows transfer of genetic material as a nucleoprotein via cell contact among bacteria. Analogously to bacterial conjug

8. DBM-Tree: trading height-balancing for performance in metric access methods
Metric Access Methods (MAM) are employed to accelerate the processing of similarity queries, such as the range and the k-nearest neighbor queries. Current methods, such as the Slim-tree and the M-tree, improve the query performance minimizing the number of disk accesses, keeping a constant height of the structures stored on disks (height-balanced trees). How

9. Modelo GAC-BRASIL: algoritmo genético aplicado à similaridade para raciocínio baseado em casos: estudo de caso em diagnóstico de cardiopatia isquêmica
The goal of Case-Based Reasoning (CBR) is to reuse known solutions to solve new problems by searching for similar cases in a base of cases. Similarity establishing criteria is one of the major issues of this Artificial Intelligence technique. The CBR module of Artificial Intelligence Applied in the Modeling and Implementation of a Virtual Medical Office Proj

Identificação, classificação e anotação de enzimas análogas em tripanossomatídeos / Identificação, classificação e anotação de enzimas análogas em tripanossomatídeos / Identification, classification and notation of analogous enzyme in Trypanosoma / Identification, classification and notation of analogous enzyme in Trypanosoma
Enzymes are proteins capable of catalyzing chemical reactions. Analogous enzymes are alternative forms of a determined enzymatic function, and are interesting subjects for the development of studies about the evolution of genes and metabolic pathways. Analogous enzymes also represent potential drug targets, since the criteria for searching and selecting thes

11. À procura do Ped bovino / Searching for the Ped gene
The aim of the present work was to identify bovine MHC class I genes similar to the murine Ped gene expressing during embryonic development and pregnancy. Bovine in vitro produced embryos and placentas obtained from natural mating or cloning-derived fetuses had their RNA extracted. cDNA was synthesized to isolate fragments showing similarity with the gene de

12. ASPECTS OF LATE SECOND TEMPLE JEWISH APOCALYPTIC: A CROSS-CULTURAL COMPARISON
Among the many difficulties raised by Second Temple Jewish apocalyptic literature (which include dating and original language of composition among other issues), one that stands out is that of the many visionary episodes described. Do they report genuine, first-hand experiences on the part of the writers, are they just a literary convention, or do they stand
