1. Comportamento mecânico, propriedades de transmissão de luz e caracterização microestrutural de cerâmica vítrea reforçada por leucita após sucessivas termo-prensagens / Microstructural characterization, mechanical and light transmitted properties of leucite-reinforced ceramic submitted to succesive thermo-processings
O objetivo neste estudo foi avaliar as propriedades mecânicas, ópticas e de superfície da cerâmica termo-prensada IPS Empress Esthetic (Ivoclar Vivadent, Schan, Liechestein). Discos cerâmicos (12 mm x 0,9 mm) foram termo-prensados em forno específico do sistema (EP 500, Ivoclar Vivadent) e serviram como controle (TP1). Remanescentes (sprues e botões c

2. Qualidade e potencial antioxidante in vitro de morangos in natura e submetidos a processamentos
Strawberries are sensory and nutritional interesting fruits. They are rich in vitamin C and phenolic compounds, being considered good sources of antioxidants, according to dietary intake recommendations for both substances. Genotype and environmental factors affect strawberry quality. High perishability and sazonality affect maturation stage in wich fruits a

3. Differential Proteomic of arabica coffee submitted to different processings and drying. / ProteÃmica Diferencial de Cafà ArÃbica Submetido a Diferentes Processamentos e Secagem.
A qualidade do cafà à fundamental nas relaÃÃes comerciais e exerce enorme influÃncia sobre o preÃo do produto. AlÃm do genÃtipo e do meio ambiente, o processamento pÃs-colheita, assim como o mÃtodo de secagem, contribui para a qualidade final da bebida. Hoje, sabe-se que a qualidade do cafà està fortemente relacionada aos eventos bioquÃmicos que

4. Processamento de amostras fecais e desenvolvimento da tecnica de analises de imagens por computador, para o diagnostico das enteroparasitoses / Processing of samples feces and development of the technique of analyses of images for computer, for the diagnosis of the enteroparasitoses
In the present study, we investigated on fecal sample processings, development and evaluation of a computer system for parasite image analysis. We observed that the fecal processing step was critical, but, essential for providing clean parasite structures, with reduced amount of fecal microdebris, to the system of computer analysis. Several conventional para

5. Qualidade da governança corporativa e participação societária dos fundos de pensão nas empresas de capital aberto brasileiras
The corporate governance normally is related with the efforts undertaken for the organization, in the direction to search the monitoring of the potential conflicts of interest between the majority, minority and managing shareholders, through the establishment of rules of conduction and behavior. This work if inserts in a group of studies that it intends to r

6. Incertezas associadas a caracterização de reservatorio utilizando dados sismicos e de poços com uma abordagem geoestatistica
A petroleum reservo ir was characterized through integration of geologic information obtained from the well and 3D seismic data. The integration was accomplished by using geoestatistical tools (kriging with extemal drift, collocated cokriging and stochastic simulation). The reservoir is composed by an altemance of turbiditic sandstone and non-reservoir facie

7. Processamento de dados multiespectrais, obtidos por plataformas orbitais da série LANDSAT, para estudos da qualidade da água na Baía de Guanabara / Processing multispectral data obtained by orbital platforms of the LANDSAT series for studies of water quality in Guanabara bay
In this paper we try to establish the grade of relationship existing among various Guanabara Bay water quality parameters and LANDSAT MSS video data. We have chosen an empirical: basis approach, but we had to select, from the available data, some parameters as follows: chlorophyll, water transparency using Secchi disk, salinity and dissolved ammonia. Only tw

8. Biosynthesis of Bacillus licheniformis penicillinase in Escherichia coli and in Bacillus subtilis.
Modified prepenicillinase was accumulated in both Escherichia coli and Bacillus subtilis treated with globomycin. Although the inhibitions of processings of prepenicillinase and prolipoprotein by globomycin in E. coli are qualitatively similar, they differ in the degree of inhibition at given concentrations of globomycin. The processing of prepenicillinase p

9. Hybrid DNA Extension and Reciprocal Exchanges: Alternative Issues of an Early Intermediate during Meiotic Recombination?
Large heterologies in gene b2 strongly increase the frequencies of reciprocal exchanges on their left border, towards the high conversion end. In a previous study, we observed that heterozygous point mutations located in the high conversion end (region F) stimulate the reciprocal exchanges instigated by the large heterology 138. We have defined some properti

10. Human genes for complement components C1r and C1s in a close tail-to-tail arrangement.
Complementary DNA clones for human C1s were isolated from cDNA libraries that were prepared with poly(A)+ RNAs of human liver and HepG2 cells. A clone with the largest cDNA insert of 2664 base pairs (bp) was analyzed for its complete nucleotide sequence. It contained 202 bp of a 5' untranslated region, 45 bp of coding for a signal peptide (15 amino acid resi

11. Gag proteins of the highly replicative MN strain of human immunodeficiency virus type 1: posttranslational modifications, proteolytic processings, and complete amino acid sequences.
The MN strain of human immunodeficiency virus type 1 was grown in H9 cells, concentrated by centrifugation, and disrupted, and proteins were purified by reversed-phase high-pressure liquid chromatography. Complete amino acid sequences were determined for the mature Gag proteins, showing natural proteolytic cleavage sites and the order of proteins (p17-p24-p2

12. Closely Related Mycobacterial Strains Demonstrate Contrasting Levels of Efficacy as Antitumor Vaccines and Are Processed for Major Histocompatibility Complex Class I Presentation by Multiple Routes in Dendritic Cells
Mycobacteria expressing recombinant antigens are already being developed as vaccines against both infections and tumors. Little is known about how dendritic cells might process such antigens. Two different mycobacterial species, the fast-growing Mycobacterium smegmatis and the slow-growing M. bovis M. bovis BCG, were engineered to express a model tumor antig
