13. Comparative study between the efficiency of the Mozzarella stretching and the holder pasteurization of milk in the inhibition of the Mycobacterium fortuitum and the Listeria monocytogenes experimentally inoculated into buffalo milk / Estudo comparativo entre a eficiência da filagem da Mozzarella e da pasteurização lenta do leite na inativação do Mycobacterium fortuitum e da Listeria monocytogenes experimentalmente inoculados no leite de búfala
Whole buffalo milk was experimentally contaminated with Mycobacterium fortuitum and Listeria monocytogenes. The quantitative analysis of the agents was made immediately before and after two thermal treatments: pasteurization (of milk) and stretching (of Mozzarella). In the analysis of the Listeria, methodology adapted for the attainment of the MPN was used,

14. Argamassa tÃrmica produzida com resÃduos da explotaÃÃo e processamento mineral de caulim e vermiculita expandid
In the last years, mining industry has been mentioned as pollutant sources of the environment, as in case of the kaolin. The pollution occurs due to the great amount of discarded materials (rejects) in the mineral processing and in the ore extraction. These rejects are frequently deposited in the ecosystem without improvement near by the processing plant How

15. Polarização da radiação galáctica em 5 GHz: instrumentação, medidas e mapas / Polarization of the galactic emission at 5 GHz: instrumentation, measurements and maps
The Galactic Emission Mapping (GEM) project was proposed in the late 1990 s, aiming to characterize the microwave emission of the Milk Way, in order to provide high quality data and models to allow a better foreground substraction of Cosmic Microwave Background maps. The project employs a 5.5 m - diameter antenna, currently operating at the Cachoeira Paulist

16. Evaluation of the use of a thermal isolation residue in the based calcium silicate in agriculture / Avaliação do uso de um resíduo de isolamento térmico a base de silicato de cálcio na agricultura
O presente estudo teve como objetivo geral avaliar a viabilidade agronômica, técnica e ambiental da destinação de um resíduo sólido a base de silicato de cálcio, proveniente de placas de isolamento térmico em tubulações superaquecidas da REDUC (Refinaria Duque de Caxias), como um insumo agrícola. Para tanto, foram conduzidos três ensaios, dividin

17. Isolamento e caracterização da lectina camptosemina extraída das sementes de Camptosema ellipticum
Lectins are (glico) proteins of non immune origin able to cause cellular agglutination or precipitation of glicoconjugates. Legume lectin refers to plant lectins that are found exclusively in species of the Leguminosae family. A notable characteristic of legume lectins is that all their proteins share tertiary structure consisting of a jelly-roll motif, whic

18. Desenvolvimento e análise de uma fornalha para aquecimento direto e indireto de ar utilizando biomassa polidispersa / Development and analysis of a furnace for both direct- and indirect air heating by using polydispersive biomass
A heat-generation system with option to direct or indirect heating of the air, that could be used in drying agricultural products or heating zootechnical facilities was developed and evaluated. The developed furnace has a heat changer with concentric countercurrent-flux tube, and it was fed polydispersive biomass by pneumatic transport or manually with bioma

19. Ritmo biolÃgico da temperatura corporal em preguiÃas (Bradypus variegatus)
Sloths are heterothermal mammals showing a mean Body Temperature (BT) of around 33ÂC, and behavioral responses possibly related with the light-dark cycle (LD) and ambient temperature. Reports on studies regarding BT rhythmicity during the 24h period are inconclusive. The aim of the present study was to characterize the biological rhythm of BT in Bradypus va

20. Taxonomy of invertebrate fossils (Oligocene-Miocene) from the King George island (West Antarctica) and paleobiogeography of cenozoic Bivalvia from Antarctica / Taxonomia de invertebrados fósseis (Oligoceno-Mioceno) da ilha Rei George (Antártica ocidental) e paleobiogeografia dos Bivalvia cenozóicos da Antártica
The research presented in this dissertation comprised part of the CNPq - PROANTAR Project 550352/02-3 "Mudanças paleoclimáticas na Antártica durante o Cenozóico: o registro geológico terrestre", which studies Cenozoic deposits from King George Island in order to elucidate the environmental and climatic Cenozoic histories of this Antarctic region. Cenozo

21. Heating systems of poultry facilities and their effects in the environmental thermal comfort, air quality and animal performance, in winter conditions, in the south area of the Brazil / Sistemas de aquecimento de aviários e seus efeitos no conforto térmico ambiental, qualidade do ar e performance animal, em condições de inverno, na região sul do Brasil
The broilers, in Its initial phase, are quite sensitive to the low temperatures, which can commit its development negatively, taking to enormous financial damages, especially in conditions of rigorous winters. With that, the great challenge initial in level of Brazil, in the poultry production, consists of the diagnosis of the situation of the Brazilian faci

22. Isolation, characterization and fermentative activity of mango pulp spoilage bacteria / Isolamento, caracterização e atividade fermentativa de bactérias deterioradoras de polpa de manga
The mango (Mangifera indica Linn.) is one of the most important tropical fruits. It is very appreciated due to its flavor and nutritional characteristics. The fruits are easily spoiled because of intrinsic factors, which makes difficult its commercialization in natura. An alternative to reduce the losts is the conservation of the mango as pulp, juice and nec

23. Effect of passion fruit (Passiflora incarnata L. 1753) on the welfare of the Nile tilapia (Oreochromis niloticus L. 1759) / Efeito do maracujá (Passiflora incarnata L. 1753) sobre o bem-estar da tilápia do Nilo (Oreochromis niloticus L. 1759)
The effects of daily administration of passion fruit (Passiflora incarnata) dry extract, on welfare, social behavior and performance of juvenile Nile tilapia, Oreochromis niloticus were studied. Juvenile males of this species (86.02 ± 5.72g) were maintained under chemical, thermal and visual isolation in glass aquariums (30L) during seven days for acclimati

24. Tecnologia LOCOS utilizando nitretos de silicio depositados por ECR-CVD / LOCOS technology using silicon nitride deposited by ECR-CVD
Silicon nitride (SiNx) insulators for LOCOS applications have been deposited by RP/RTCVD and ECR-CVD at room temperature, at low pressure (5mTorr), with N2 flows of 2.5, 5, 10 and 20sccm with fixed SiH4/Ar flows of 200/20sccm with a microwave power of 1000W on SiO2-Pad/Si and Si substrates. SiNx/Si structures were obtained to analyze the physical characteris
