1. Avaliação de Processos GMAW Duplo-Arame em Baixa Corrente com Controle do Formato de Onda e com Auxílio de Feixe de Laser / Assessment of Low Current Tandem GMAW Processes with Waveform Control and with Aid of Laser Beam
In face of manufacturing-related limitations in the present-day industry, the welding sector has looked for new, or even not so new, processes. In other words, it has invested in the development of new processes and, especially, in the use of new arrangements for conventional processes. Thus, the aim of this work was to assess the use of combined processes a

2. Aprendendo línguas estrangeiras in-tandem: histórias de identidades
A Pesquisa Narrativa de Clandinin & Connelly (2000) compreende a experiência humana como histórias vividas e contadas. Nesta abordagem qualitativa de pesquisa, os participantes contam histórias e os pesquisadores as recontam e as reconstroem por meio de narrativas acerca das experiências. Tendo este arcabouço metodológico como orientador de nossos proc

3. Transcriptional regulation of fis operon involves a module of multiple coupled promoters
The transcription of the Escherichia coli fis gene is strongly activated during the outgrowth of cells from stationary phase. The high activity of the promoter of the fis operon requires the transcription factor IHF. Previously, we identified a divergent promoter, div, located upstream of the fis promoter. In this study we demonstrate that at least two addit

4. Arrayed transposase-binding sequences on the ends of transposon Tn5090/Tn402
The transposon Tn5090/Tn402 encodes a 559 amino acid transposase, TniA, with a DDE motif. Gel mobility shifting and cleavage protection analysis with DNase I and hydroxyl radical probes revealed that TniA binds to multiple repeat sequences on either terminus of Tn5090/Tn402. Four of these TniA-binding 19mers occurred on the left-hand (t) end and two on

5. Binding site for Robo receptors revealed by dissection of the leucine-rich repeat region of Slit
Recognition of the large secreted protein Slit by receptors of the Robo family provides fundamental signals in axon guidance and other developmental processes. In Drosophila, Slit–Robo signalling regulates midline crossing and the lateral position of longitudinal axon tracts. We report the functional dissection of Drosophila Slit, using structure analysis,

6. The Quaternary Structure of Amalgam, a Drosophila Neuronal Adhesion Protein, Explains Its Dual Adhesion Properties
Amalgam (Ama) is a secreted neuronal adhesion protein that contains three tandem immunoglobulin domains. It has both homophilic and heterophilic cell adhesion properties, and is required for axon guidance and fasciculation during early stages of Drosophila development. Here, we report its biophysical characterization and use small-angle x-ray scattering to d

7. Topography of the histone octamer surface: repeating structural motifs utilized in the docking of nucleosomal DNA.
The histone octamer core of the nucleosome is a protein superhelix of four spirally arrayed histone dimers. The cylindrical face of this superhelix is marked by intradimer and interdimer pseudodyad axes, which derive from the nature of the histone fold. The histone fold appears as the result of a tandem, parallel duplication of the "helix-strand-helix" motif

8. Deletion of the GATA Domain of TRPS1 Causes an Absence of Facial Hair and Provides New Insights into the Bone Disorder in Inherited Tricho-Rhino-Phalangeal Syndromes
GATA transcription factors mediate cell differentiation in diverse tissues, and their dysfunction is associated with certain congenital human disorders. The six classical vertebrate GATA proteins, GATA-1 to GATA-6, are highly homologous, bear two tandem zinc fingers of the C4 (GATA) type, and activate transcription. TRPS1, the only other vertebrate protein w

9. Intra- and intermolecular cooperative binding of high-mobility-group protein I(Y) to the beta-interferon promoter.
The mammalian high-mobility-group protein I(Y) [HMG I(Y)], while not a typical transcriptional activator, is required for the expression of many eukaryotic genes. HMG I(Y) appears to recruit and stabilize complexes of transcriptional activators through protein-DNA and protein-protein interactions. The protein binds to the minor groove of DNA via three short
