1. Hybrid Materials Based on Bentonite Functionalized with Amine Groups via the Hydrolytic Sol-Gel Method
Bentonite is a natural clay that presents characteristics such as good capacity to exchange cations, large specific surface area, large porosity, and possibility to undergo intercalation and/or functionalization. This work reports on bentonite functionalization with organomodified alkoxides. Functionalization afforded hybrid materials displaying desirable pr

2. The university professors new roles faced to the information and communication technologies / Os novos papéis do professor universitário frente às tecnologias da informação e comunicação
This thesis investigates the University Professors New Roles faced to the Information and Communication Technologies (ICT). As a support of the investigation, it was tried, by means of theoretical foundation, to base the studies that were developed together, such as: the ICT contribution for the development and improvement of the proposals and projects, both

3. Development of membrane biosensors and characterization of the interactions between cytochrome c and hybrid bilayer membranes by Surface Plasmon Resonance / Desenvolvimento de biosensores de membranas e caracterização da interação entre citocromo c e bicamadas híbridas por ressonância plasmônica de superfície
The aim of this work was to develop membrane biosensors based on Surface Plasmon Resonance (SPR) and to apply them to study the interactions between cytochrome c (cyt c) and model membranes. SPR is an optical technique that provides high-sensitivity measurements of refractive index (n), allowing the characterization of the adsorption and desorption of molecu

5. OPÇÕES REAIS HÍBRIDAS COM APLICAÇÕES EM PETRÓLEO / HYBRID REAL OPTIONS WITH PETROLEUM APPLICATIONS
This methodological and normative thesis extends the modern economic valuation theory of projects under uncertainty, known as real options theory, from the point of view of an oil company that optimizes the allocation of investment and resources. The real options theory is combined with other theories - so the name hybrid real options - in order to perform a

6. Modelo de avaliação de cooperativa ? escola: instrumental testado nas unidades escolares da Bahia.
The main issue of this work is the Cooperative-school, which is identified as a social institution that promotes education and preparation for the job market. However, the question here is: What is the category of a Cooperative-school that simultaneously promotes educative activities and generation of jobs and income? This question relocates the investigatio

7. A critical arginine residue mediates cooperativity in the contact interface between transcription factors NFAT and AP-1
The heterologous transcription factors NFAT and AP-1 coordinately regulate cytokine gene expression through cooperative binding to precisely juxtaposed DNA recognition elements. The molecular origins of cooperativity in the binding of NFAT and AP-1 to DNA are poorly understood. Herein we have used yeast one-hybrid screening and alanine-scanning mutagene

8. Single residue modification of only one dimer within the hemoglobin tetramer reveals autonomous dimer function
The mechanism of cooperativity in the human hemoglobin tetramer (a dimer of αβ dimers) has historically been modeled as a simple two-state system in which a low-affinity structural form (T) switches, on ligation, to a high-affinity form (R), yielding a net loss of hydrogen bonds and salt bridges in the dimer–dimer interface. Modifications that weaken the

9. Cooperative Interactions in Aspartate Transcarbamoylase. 1. Hybrids Composed of Native and Chemically Inactivated Catalytic Polypeptide Chains
Hybrids of aspartate transcarbamoylase (EC 2.1.3.2; carbamoylphosphate: L-aspartate carbamoyltransferase) from Escherichia coli containing native (active) and pyridoxylated (inactive) catalytic polypeptide chains were constructed by a procedure involving the reversible acylation of amino groups with 3,4,5,6-tetrahydrophthalic anhydride. This technique exploi

10. Dual role of the nuclear factor of activated T cells insert region in DNA recognition and cooperative contacts to activator protein 1
The transcription factors nuclear factor of activated T cells (NFAT) and activator protein 1 (AP-1) coordinately regulate cytokine gene expression in activated T-cells by binding to closely juxtaposed sites in cytokine promoters. The structural basis for cooperative binding of NFAT and AP-1 to these sites, and indeed for the cooperative binding of transcript

11. Cooperative transcriptional activity of Jun and Stat3 beta, a short form of Stat3.
To identify proteins that regulate the transcriptional activity of c-Jun, we have used the yeast two-hybrid screen to detect mammalian polypeptides that might interact functionally with the N-terminal segment of c-Jun, a known regulatory region. Among the proteins identified is a short form of Stat3 (designated Stat3 beta). Stat3 beta is missing the 55 C-ter

12. Residues in the Swi5 Zinc Finger Protein That Mediate Cooperative DNA Binding with the Pho2 Homeodomain Protein
The Swi5 zinc finger and the Pho2 homeodomain DNA-binding proteins bind cooperatively to the HO promoter. Pho2 (also known as Bas2 or Grf10) activates transcription of diverse genes, acting with multiple distinct DNA-binding proteins. We have performed a genetic screen to identify amino acid residues in Swi5 that are required for synergistic transcriptional
