1. Characterization of the omlA gene from different serotypes of Actinobacillus pleuropneumoniae: a new insight into an old approach
The OmlA protein is a virulence factor of Actinobacillus pleuropneumoniae, an important pathogen in pigs. The polymorphisms present in the omlA gene sequence of 15 reference serotypes of A. pleuropneumoniae and non-serotypable isolates were assessed to determine the possible evolutionary relationship among them and to validate the importance of this gene as

2. Investigação sobre a implantação de loteamentos e a ocorrência de processos erosivos: voçoroca situada no Jardim Santa Edwirges em Ponta Grossa - PR
The urban area of Ponta Grossa city, located in Parana state, South of Brazil, has different kinds of erosion process, as landslides, river erosion, hillslopes, piping and gully erosion. These processes occur even in authorized as much as in unauthorized areas. The present research intends to comprehend the relations connecting the urban planning and the ero

3. Influence factors on forging die wear of automotive connecting rods / Fatores de influencia no desgaste de matrizes de forjamento a quente de bielas automotivas
A significant part of forgings prices is due to costs from reworks of forging dies because of superficial failures on their surfaces. In quest of a higher competitiveness in terms of prices and production times, it is necessary to understand the mechanisms of die failure to increase its working life, avoiding risk situations and a possible total failure of t

4. Factors structuring fish assemblages in three distinct zones (river, mixture and coastal) of the rio Mambucaba estuary, Angra dos Reis-RJ. / Fatores estruturadores das assembléias de peixes em três distintas zonas (rio, mistura e costeira) do estuário do rio Mambucaba, Angra dos Reis- RJ.
The estuarine systems influence fish assemblages, throughout their longitudinal gradients and remarkable salinity changes. Such assemblages adapt to different habitat constraints and change in spatial and temporal scales. The aim of this study was to assess the ichthyofauna composition and structure in three zones of the Mambucaba estuary (CZ coastal zone; M

5. Atribuição da guarda e suas conseqüências em direito internacional privado / Atribuição da guarda e suas conseqüências em direito internacional privado
A presente tese diz respeito à análise das hipóteses de atribuição da guarda dos filhos incapazes de pessoas que, por alguma razão, vivam separadamente, desmanchando eventual vínculo familiar entre elas existente. Corno esse fato não é apto a desfazer os vínculos entre cada um dos genitores e seus filhos, torna-se imperiosa a atribuição da guarda

6. DESENVOLVIMENTO E IMPLEMENTAÇÃO DE UMA MICRO-REDE AVANÇADA DE ALTA FREQÜÊNCIA PARA INTEGRAÇÃO DE FONTES ALTERNATIVAS DE ENERGIA / DEVELOPMENT AND IMPLEMENTATION OF AN ADVANCED HIGH FREQUENCY MICROGRID FOR INTEGRATION OF ALTERNATIVE ENERGY SOURCES
This Thesis presents a distributed generation system, which works as a Microgrid, suitable to integrate alternative energy sources, using a high frequency AC link (HFAC) as a means of connecting sources and loads. The static compensation of current harmonics, reactive power and voltage harmonics, which can be found in the Microgrid, is considered a key facto

7. Fatores geneticos moduladores da gravidade clinica nas Beta-talassemias : o exemplo da proteina AHSP (Alpha Hemoglobin Stabilizing Protein)
Alpha-hemoglobin stabilizing protein (AHSP) is an erythroid-specific molecular chaperone that binds the cx-chains of hemoglobin, preventing their precipitation and deleterious effects. Loss of AHSP exacerbates a-globin precipitation and anemia in a murine model for p-thalassemia. In vitro, recombinant AHSP inhibits the production of reactive oxygen species (

8. Escola aprendente: desafios e possibilidades postos no contexto da sociedade do conhecimento.
The nowadays school is focused on the rationality of the writing itself. It failed when it tried to embrace the rationality of the speech, it also failed in embracing the complexity of nowadays world and in embodying the new forms of thought, new forms of organization and new forms of building knowledge that are emerging with information and communication te

9. Cloning of a cDNA coding for human factor V, a blood coagulation factor homologous to factor VIII and ceruloplasmin.
Coagulation factor V is a high molecular weight plasma glycoprotein that participates as a cofactor in the conversion of prothrombin to thrombin by factor Xa. A phage lambda gt11 Hep G2 cell cDNA expression library was screened by using an affinity-purified antibody to human factor V, and 11 positive clones were isolated and plaque-purified. The clone contai

10. Structural details of the binding of guanosine diphosphate to elongation factor Tu from E. coli as studied by X-ray crystallography.
Structural details of the guanosine diphosphate binding to a modified form of elongation factor Tu from Escherichia coli, resulting from X-ray crystallographic studies, are reported. The protein elements that take part in the nucleotide binding are located in four loops connecting beta-strands with alpha-helices. These loops correspond to regions in primary

11. A retinitis pigmentosa GTPase regulator (RPGR)- deficient mouse model for X-linked retinitis pigmentosa (RP3)
The X-linked RP3 locus codes for retinitis pigmentosa GTPase regulator (RPGR), a protein of unknown function with sequence homology to the guanine nucleotide exchange factor for Ran GTPase. We created an RPGR-deficient murine model by gene knockout. In the mutant mice, cone photoreceptors exhibit ectopic localization of cone opsins in the cell body and synap

12. Protein Kinase C-α Phosphorylation of Specific Serines in the Connecting Segment of the β4 Integrin Regulates the Dynamics of Type II Hemidesmosomes
Although the regulation of hemidesmosome dynamics during processes such as epithelial migration, wound healing, and carcinoma invasion is important, the mechanisms involved are poorly understood. The integrin α6β4 is an essential component of the hemidesmosome and a target of such regulation. Epidermal growth factor (EGF) can induce hemidesmosome disassemb
