3. Estudo do moonpool como sistema de minimização de movimento em uma plataforma do tipo monocoluna. / Study of moonpool as a motion minimization device in a monocolumn type platform.
A maioria dos estudos realizados sobre moonpools existentes em embarcações sempre objetivou a redução das amplitudes de oscilação da água interna a estes, pois sua usual utilização é a passagem de linhas de produção, equipamentos e mergulhadores. Estes estudos mostram que com a mudança da geometria interna do moonpool é possível alterar o comp

4. Quantificação de estigmatadienos em azeite de oliva (Olea europea L.) por cromatografia em fase gasosa. / Stigmastadiene quantification in olive oil (Olea europaea L.) by gas chromatography.
The olive oil is a product with high nutricional value and has been conquesting their space in the consumer market due to their organoleptic characteristics (aroma and taste). The cultivation of olive trees, the harvesting of the olive fruits, and the extraction of olive oil are hard and time-consuming tasks, contribuing to it high commercial price. Therefor

5. Purificação parcial, propriedades e caracterização cinética de proteases tripsina-like do intestino médio da lagarta da soja, Anticarsia gemmatalis / Partial purification, properties and kinetics characterization of midgut trypsin-like proteases from the velvetbean caterpillar, Anticarsia gemmatalis
The identification and characterization of proteases from the insect midgut are of great importance for research and development pest resistant cultivars of crop species. Different processes of trypsin-like proteases purification from midgut A. gemmatalis and characterization of these proteases were carried out in this work. Two fractions were isolated durin

7. Purification and investigation of the physical-chemical protease inhibitors properties from acacia plumosa lowe seeds. / Purificação e investigação de propriedades físico-químicas de inibidores de proteases extraídos das sementes de aácia plumosa Lowe.
Seeds of plants belonging to Leguminosae family are rich sources of protease inhibitors. The Acacia genus is one of the most important members of this group. In this work, novel protease inhibitors from Acacia plumose Lowe seeds have been described. From the saline extract of mature seeds, the inhibitors were purified by size exclusion chromatography on Supe

8. Quantificação de fitosterois em azeite de oliva (Olea europaea) por cromatografia em fase gasosa / Quantification of fitosteróis in oil of oliva (europaea Olea) for chromatography in gaseous phase
The detection of frauds in olive oil has been on the increase in the recent years, being the control almost inexistent in Brazil. With the intention to make it available another olive oil detection tool adulterations to the inspection and quality control sector it was accomplished in this work the methodology adequacy to determinate the phytosterols composit

9. Atividade indutora de fitoalexinas e produção de substancias fungitoxicas durante a germinação de sementes de Sesbania marginata Benth
Sesbania marginata Benth is a tropical legume that stores galactomannan in its thickened endospermic cell walls. These polysaccharides are composed of a linear backbone of 13-1,4- linked D-mannose residues to which D-galactose residues are attached by a-1,6 linkages. Following germination, the galactomannan is completely broken down producing considerable am

10. Epoxidação de oleo de soja catalisada por CH3ReO3
The effect of nitrogen-containing bases on the activity and selectivity of the epóxidation of soybean oil catalyzed by CH3ReO3/H2O2 was investigated. This catalytic system was studied in homogeneous and heterogeneous phase. Initially the methyl esters of soybean oil were epóxidized using peracetic acid. The main products of the reactions were separated usi

11. PO41, uma anti-hemorragina presente no soro de Philander opossum: isolamento, caracterização e interação com metaloproteases isoladas do veneno de Bothrops jararaca. / PO41, the anti-hemorragina present in the serum of Philander opossum: isolation, characterization and interaction with metalloproteases isolated of the poison of Bothrops jararaca
An antihaemorrhagic factor from Philander opossum serum was isolated and characterizated. In order to study the neutralization effect of this inhibitor, we have developed a new methodology to isolate a PI as well as PIII SVMP from Bothrops jararaca venom (Bjv). The antihaemorrhagic protein was isolated from Philander opossum serum by DEAE-Sephacel, Phenyl Su

12. Purificação e caracterização de enterohemolisina produzida por Escherichia coli enteropatogenicas
Enterohaemolysins (EHly) were ftrst detected in classical enteropathogenic Escherichia coZi strains (EPEC), isolated from feces of infants with diarrhea, and also detected in strains isolated from animaIs. Differring from a-haemolysin, EHly is not spontaneously released to culture medium. Sonication was the most efficient method to extract EHly. In order to
