1. Abordagem para otimização multiobjetivo de regras heurísticas de sequenciamento em sistemas de manufatura job shop por meio de simulação computacional acoplada ao algoritmo genético. / Approach for optimization of heuristic rules multiobjetivo sequencing in job shop manufacturing systems through simulation coupled with genetic algorithm.
Desde o surgimento do Sistema Toyota de Produção (STP), conhecido por produção enxuta, e mais recentemente as exigências do mercado consumidor, as empresas de manufatura têm trabalhado para melhorar seus processos de produção, com objetivo de reduzir níveis de estoque, eliminar desperdícios, manter/aumentar a qualidade, a competitividade e o lucro.

2. A computer simulation model for scheduling operations in assembly shop systems. / Proposta de um modelo de simulação computacional para a programação de operações em sistemas assembly shop.
This dissertation studies the problem of scheduling operations in manufacturing job shop environments where items with bill of materials are made of many fabricated and assembled components. Such systems are known as assembly shops. The general job shop scheduling problem, which no restrictions exist neither for the number of operations to be scheduled nor f

3. 5S rDNA characterization in twelve Sciaenidae fish species (Teleostei, Perciformes): depicting gene diversity and molecular markers
In order to extend the genetic data on the Sciaenidae fish family, the present study had the purpose to characterize PCR-generated 5S rDNA repeats of twelve species of this group through PAGE (Polyacrylamide Gel Electrophoresis) analysis. The results showed the occurrence of at least two different 5S rDNA size classes in all the species. Moreover, 5S rDNA re

4. Rastreabilidade de soja Roundup Ready® em produtos agrícolas e derivados: produção de materiais de referência e uso de marcadores AFLP / Roundup Ready® transgenic soybean traceability in agrifood products and derivatives: reference materials production and the use of AFLP markers
The introduction of soybean transgenic cultivars brought several changes in both world trade and regulation rules for producers and consumers, mainly in relation to certification, traceability, biosafety and labeling. Soybean is one of the largest commodities in the world trade and responsible for half of the Brazilian export incomings, present as raw materi

5. O gene da miogenina: sequenciamento em suínos e análise filogenética / The myogenin gene: sequencing in swine and phylogenetic analysis
Meat production capacity is related to muscle fibers number show in newborn animals. The muscle fibers are formed in the myogenesis that takes place during the embryonic development, an event that is controlled in part by the MyoD gene family. The Myogenin gene is a member of this family and rules the expression of muscle specific genes. It has an important

6. Compreensão sociológica de prática pedagógica de matemática : um olhar a partir de Basil Bernstein
This study aims to investigate how two Mathematic teachers ¿ one of them teaching two classes ¿ from the Rio Grande do Sul public educational system define their curricula and perform their pedagogical practice comparing them as to the students¿ best performance in this subject. The qualitative methodology guided the development of this work, data being c

7. A Model of the Statistical Power of Comparative Genome Sequence Analysis
Comparative genome sequence analysis is powerful, but sequencing genomes is expensive. It is desirable to be able to predict how many genomes are needed for comparative genomics, and at what evolutionary distances. Here I describe a simple mathematical model for the common problem of identifying conserved sequences. The model leads to some useful rules of th

8. Syntactic sequencing in Hebbian cell assemblies
Hebbian cell assemblies provide a theoretical framework for the modeling of cognitive processes that grounds them in the underlying physiological neural circuits. Recently we have presented an extension of cell assemblies by operational components which allows to model aspects of language, rules, and complex behaviour. In the present work we study the genera

9. Molecular Identification and Epidemiological Tracing of Pasteurella multocida Meningitis in a Baby
We report a case of Pasteurella multocida meningitis in a 1-month-old baby exposed to close contact with two dogs and a cat but without any known history of injury by these animals. 16S rRNA gene sequencing of the isolate from the baby allowed identification at the subspecies level and pointed to the cat as a possible source of infection. Molecular typing of

10. Nucleotide sequence of a Euglena gracilis chloroplast genome region coding for the elongation factor Tu; evidence for a spliced mRNA.
We characterize a 1.95 kb transcription product of the Euglena gracilis chloroplast DNA fragment Eco-N + Q by S1 nuclease analysis and DNA sequencing and show that it is the product of three splicing events. Exon 1 (0.45 kb), exon 2 (0.74 kb) and 175 nucleotides of exon 3 (0.53 kb) code for the chloroplast elongation factor protein (EF-Tu). The remaining par

11. Flytrap, a database documenting a GFP protein-trap insertion screen in Drosophila melanogaster
Flytrap is a web-enabled relational database of transposable element insertions in Drosophila melanogaster. A green fluorescent protein (GFP) artificial exon carried by a transposable P-element is mobilized and inserted into a host gene intron creating a GFP fusion protein. The sequence of the tagged gene is determined by sequencing inverse-PCR products deri

12. The EMBL Nucleotide Sequence Database
The EMBL Nucleotide Sequence Database (http://www.ebi.ac.uk/embl), maintained at the European Bioinformatics Institute (EBI) near Cambridge, UK, is a comprehensive collection of nucleotide sequences and annotation from available public sources. The database is part of an international collaboration with DDBJ (Japan) and GenBank (USA). Data are exchanged dail
