1. Calibração multivariada de redes de abastecimento de água via algoritmo genético multiobjetivo
RESUMO Este trabalho teve por objetivo propor um modelo computacional com vistas à calibração multivariada de modelos hidráulicos de sistemas de distribuição de água que possibilita a identificação de possíveis irregularidades, como: vazamentos, obstruções nas tubulações, válvulas inoperantes ou estranguladas e incompatibilidades na modelagem

2. Segurança para o sistema brasileiro de televisão digital: contribuições à proteção de direitos autorais e à autenticação de aplicativos. / Security on brazilian digital television system: contributions to the digital rights protection and to applications authentication.
In Brazil, the television system is considered an important source of communication and entertainment. The Brazilian digital transmissions started on December 2007 and first offered functionalities were the high definition, mobility and portability. In a later moment other functionalities will be added: multiprogramming (more than one service per channel) an

3. The use of structural parts of the buildings as part of the lightning protection systems - the physical damages aspects. / Uso de componentes naturais de edificações como parte integrante do sistema de proteção contra descargas atmosféricas - uma visão relativa aos danos físicos.
This work presents some specific aspects on the subject lightning protection of structures, mainly when the use of structural parts of the buildings as part of the protection systems is concerned. Several polemical issues are discussed, such as: special air-termination, the dissipation array system and the use of steel-reinforcing rods of the reinforced

4. Estudo e construção de uma antena para gerar campos eletromagnéticos similares aos campos criados por uma descarga atmosférica
Os critérios de projeto atualmente estabelecidos nas normas brasileiras não levam em consideração de forma explícita a proteção contra as sobretensões causadas pela interação dos campos eletromagnéticos da descarga atmosférica e os condutores da edificação. Uma das razões para este fato é que a quantificação destas sobretensões atráves de

5. Five genes involved in self-transmission of pSN22, a Streptomyces plasmid.
An 11-kbp multicopy plasmid, pSN22, was isolated from Streptomyces nigrifaciens SN22. pSN22 is self-transmissible (conjugative), is maintained stably in S. lividans, and forms pocks in a wide range of Streptomyces strains. Mutational analyses showed that a fragment of pSN22 contained five genes involved in plasmid transfer and pock formation. traB was essent

6. Transfer functions of the conjugative integrating element pSAM2 from Streptomyces ambofaciens: characterization of a kil-kor system associated with transfer.
pSAM2 is an 11-kb integrating element from Streptomyces ambofaciens. During matings, pSAM2 can be transferred at high frequency, forming pocks, which are zones of growth inhibition of the recipient strain. The nucleotide sequences of the regions involved in pSAM2 transfer, pock formation, and maintenance have been determined. Seven putative open reading fram

7. Complete nucleotide sequence of the Streptomyces lividans plasmid pIJ101 and correlation of the sequence with genetic properties.
The complete nucleotide sequence of the multicopy Streptomyces plasmid pIJ101 has been determined and correlated with previously published genetic data. The circular DNA molecule is 8,830 nucleotides in length and has a G+C composition of 72.98%. The use of a computer program, FRAME, enabled identification in the sequence of seven open reading frames, four o

8. Regulation and function of the Streptomyces plasmid pSN22 genes involved in pock formation and inviability.
pSN22 is an 11-kb multicopy plasmid from Streptomyces nigrifaciens which is being studied in Streptomyces lividans. A segment of about 7 kb of pSN22 contains five genes involved in conjugation. Three of them, traA, traB, and traR, are essential for plasmid transfer and for the mobilization of chromosomal markers (fertility), while the remaining two genes, sp

9. SPD—a web-based secreted protein database
With the improved secreted protein prediction approach and comprehensive data sources, including Swiss-Prot, TrEMBL, RefSeq, Ensembl and CBI-Gene, we have constructed secretomes of human, mouse and rat, with a total of 18 152 secreted proteins. All the entries are ranked according to the prediction confidence. They were further annotated via a proteome ann
