13. Compósitos cerâmicos porosos de alumina - zircônia para aplicação em sistemas de controle térmico para satélites: obtenção e caracterização / Alumina-zirconia porous ceramic composites for application in satellite thermal control systems: obtaining and characterization
To control the temperature of satellites are used various thermal control heat systems. The Loop Heat pipe (LHP) are being developed at the DEM (Space Mechanic and Control Division) of the INPE (National Institute for Space Research) an apparatus for passive heat control of the satellites components. The main components of the LHP system are: capillary evapo

14. Optimization of contained fluid structures subjected to multiple load cases. / Otimização de estruturas com fluido contido sujeita a múltiplos carregamentos.
Several times, it is found in Engineering, structures with fluid inside (contained fluid structures). Since for some load cases, for instance, hydrostatic load, the fluid collaborates with stiffness, it may be convenient for the engineer to take into account this fluid to make the structure lighter, mainly if the presence of fluid is mandatory for operation.

15. Efeito de frações obtidas da fucoidana de Fucus vesiculosus em modelo experimental de artrite induzida por Zymosan
The fucoidan from Fucus vesiculosus is known for having diverse biological properties. This study analyzed the therapeutic action of populations of commercial fucoidan (F. vesiculosus) on zymosan-induced arthritis. Three populations of fucoidan were obtained after acetone fractionation; these were denominated F1 (52.3%), F2 (36.7%) and F3 (10.7%). Chemical a

16. A utilização de fluido de corte no fresamento do aço inoxidavel 15-5PH / The cutting fluid utilization in the stainless steel 15-5PH milling
The preciptation hardenable stainsless steel presents high mechanical strength and corrosion resistance, having a wide application field, specially in the aerospace industry. The present work evaluated the influence of cutting fluids in the 15-5PH stainless steel milling, using carbide tools, TiAIN coated. Experiments were carried out for roughing and finish

17. Parâmetros inflamatórios, imunológicos e histopatológicos da administração prolongada da Ipomoea carnea em ratos: 1. Avaliação em animais adultos 2. Estudo perinatal / Inflammatory, immunological and histopathological parameters of prolonged administration of Ipomoea carnea in rats: 1. Evaluation of adult animals 2. Perinatal study
The aim of this study was to evaluate the toxic effect of I. Carnea and its toxins on the immune system of rats, and to evaluate its effects on mothers and offspring when administered to dams during gestation or lactation. An alkaloid-rich plant extract (RAF) was added to drinking water to obtain doses equivalent to 3.0 and 15.0g/kg of dry leaves for 14 and

18. SENSOR DISCRIMINATIVO A FIBRA ÓPTICA PARA DETECÇÃO DE VAZAMENTO EM TANQUES JAQUETADOS / OPTICAL FIBER SENSOR DISCRIMINATOR FOR JACKETED TANKS LEAKAGE DETECTION
Soil contamination due to leakage of hydrocarbon fuels from tanks in service stations is an environmental risk associated with the distribution segment of the petroleum industry. Such risk is closely related to ageing tanks and piping systems, as well as to the lack of quality assurance practices in service stations. This problem is being reduced during the

19. Metodologia de obtenção de resultados em fluido-dinamica computacional : aplicação a reatores tanques agitados
In this thesis, procedure for obtaintion of vector and scalar fields is shown and applied to stirred tank reactors. The methodology of the present work is emphasized through case studies with a Newtonian fluid, water, and a non-Newtonian system, polystyrene. Both fluids are contained inside a stirred tank reactor. The system stirred tank reactors is studied

20. Analise termica parametrica de dispositivo aletado de geometria retangular contendo material de mudança de fase
A two-dimensional numerical model is used for the problem offusion (solidification) of phase change material contained in a metallic rectangular device. A standard configuration is chosen for which geometric parameters such as width, fin height, fin width, base and top width are investigated. Operational parameters such as heat flux magnitude, heat flux peri

21. Spectrophotometric measurement of proteoglycans in osteoarthritic synovial fluid.
Cartilage glycosaminoglycans (GAGs) were measured by a spectrophotometric assay in synovial fluid obtained from 30 normal bovine hock joints and 15 osteoarthritic human knee joints. Results were compared with those obtained by radioimmunoassay (RIA). The spectrophotometric method (dimethylmethylene blue (DMB) assay) was found to be simple, safe, and sufficie

22. Survey of synovial fluid cryoprecipitates.
Synovial fluid cryoproteins from various inflammatory and noninflammatory arthritides were examined for the presence of immunoglobulin, fibrinogen, antiglobulin activity, and third component of complement and correlated with the synovial fluid leucocyte count. The majority of rheumatoid synovial fluid cryoproteins contained either IgG-IgM complexes or IgG al

23. Cultured human amniotic fluid cells characterized with antibodies against intermediate filaments in indirect immunofluorescence microscopy.
Cells cultured from second trimester human amniotic fluid were characterized in indirect immunofluorescence (IIF) microscopy using specific antibodies against the subunit proteins of different types of cytoskeletal intermediate filaments. Most of the amniotic fluid cell cultures contained only epithelial cells as indicated by the positive keratin-fluorescenc

24. Naturally occurring anti-inflammatory factors in the synovial fluids of patients with rheumatic disease and their possible mode of action.
Evidence has been shown that pathological synovial fluid contained a substance capable of stabilizing rat liver lysosomes which was partly inactivated by treatment with trypsin and by storage. Such synovial fluid also appeared to contain a substance which labilized lysosomes and which was more stable than the stabilizing substance. (2) The lysosomal stabiliz
