13. The correlation between the central carbon metabolic flux distribution and the number of shared enzyme regulators in Saccharomyces cerevisiae
The central carbon metabolic system is the upstream energy source for microbial fermentation. In addition, it is a master switch for increasing the production of metabolites and an important part of the microbial metabolic network. Investigation into the relationship between genes, environmental factors, and metabolic networks is a main focus of systems biol

14. Medicinal plants traded in the open-air markets in the State of Rio de Janeiro, Brazil: an overview on their botanical diversity and toxicological potential
Medicinal plants have been used for many years and are the source of new active substances and new drugs of pharmaceutical interest. The popular knowledge contained in the open-air markets is studied through urban ethnobotany, and is a good source of information for ethnobotanical research. In this context, we surveyed the literature on works concerning open

15. Carabid beetle assemblages in three environments in the Araucaria humid forest of southern Brazil
Carabid beetle assemblages in three environments in the Araucaria humid forest of southern Brazil. Carabidae is composed mainly by ground-dwelling predator beetles. It is the fourth most diverse group within Coleoptera, but its diversity in the Neotropical region is understudied. Here we describe and analyze the diversity of carabid beetles in a region of su

16. Optimizing similarity queries in metric spaces meeting user\ s expectation / Otimização de operações de busca por similaridade em espaços métricos
The complexity of data stored in large databases has increased at very fast paces. Hence, operations more elaborated than traditional queries are essential in order to extract all required information from the database. Therefore, the interest of the database community in similarity search has increased significantly. Two of the well-known types of similarit

17. Caracterização bioquímica e biofísica da Celobiohidrolase II do fungo Trichoderma harzianum IOC3844 produzida por expressão homóloga / Biochemical and biophysical characterization of cellobiohydrolase II from Trichoderma harzianum IOC 3844 produced by homologous expression
The depletion of reserves, especially of refined oil , with increased energy demands and the urgent need to reduce the carbon emissions on the atmosphere, signals the necessity to search for new sources of energy renewable and clean. Concerns about global warming have led to an increased world interest in biofuels. The new concept of second generation biofue

18. 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

19. RANKING OF WEB PAGES BY LEARNING MULTIPLE LATENT CATEGORIES / CLASSIFICAÇÃO DE PÁGINAS WEB POR APRENDIZAGEM DE MÚLTIPLAS CATEGORIAS LATENTES
The rapid growth and generalized accessibility of the World Wide Web (WWW) have led to an increase in research in the field of the information retrieval for Web pages. The WWW is an immense and prodigious environment in which Web pages resemble a huge community of elements. These elements are connected via hyperlinks on the basis of similarity between the co

20. A relação entre conhecimento ecológico, preocupação ecológica, afeto ecológico, normas subjetivas e o comportamento de compras verdes no setor de cosméticos / The relationship between ecological knowledge, ecological concern, ecological affection and subjective standards of green shopping behavior in the cosmetics industry
Research which seeks to investigate the relationship between environmental factors and the consumer behavior is still embryonic in Brazil, which is a unique opportunity for those studies that relate the purchasing behavior of consumers to environmental issues. In this perspective, the goal of this research was to ascertain whether there is correlation betwee

21. A desigualdade em saúde e o baixo peso ao nascer : uma revisão sistemática com metanálise
Considering the hypothesis that an excessive use of new technologies and the lack of heath resources can present similar outcomes concerning low weight rates at birth (LWB), it was analyzed the association between the social standing, which was obtained from the maternal schooling, profession and income, and the low weight rates at birth. It deals with a lit

A disseminação de grandes coleções de arquivos de imagens, músicas e vídeos tem aumentado a demanda por métodos de indexação e sistemas de recuperação de informações multimídia. No caso de imagens, os sistemas de busca mais promissores são os sistemas baseados no conteúdo, que ao invés de usarem descrições textuais, utilizam vetores de car

24. Abordagens heurísticas para problemas de agrupamentos / Heuristics approaches for clustering problems
The clustering problems arose from the need to group data in order to understand an object or a phenomenon still unknown. Data clustering is based on similarity between objects of a data set, where the most similar objects are in the same group. This work proposes three new heuristics approaches to clustering problems: the \textit{Variable Neighborhood Searc
