13. Painéis-sanduíche com núcleo de EPS reciclado: metodologia de execução e determinação de propriedades termofísicas
Novos materiais desenvolvidos a partir de resíduos industriais vêm sendo estudados como alternativa aos modelos tradicionalmente empregados na construção civil. Para desenvolvimento desses materiais são considerados fatores como: custo, eficiência e redução de passivo ambiental. No caso específico de materiais para aplicação em habitações situad

14. Desenvolvimento e caracterização de compósitos sanduíche para isolamento térmico
Um painel sanduíche consiste essencialmente em duas faces, podendo inclusive possuir reforços metálicos e um núcleo formado normalmente por um polímero celular. As faces deste tipo de painel podem estar unidas por um adesivo estrutural, ou por espuma rígida de poliuretano (PU) injetado diretamente sobre os substratos, quando a união ocorrerá naturalm

15. Otimização de painéis sanduíche utilizando o método de recozimento simulado / Optimization of a sandwich panels by using the simulated annealing method
A redução da massa de estruturas espaciais é importante, pois possibilita o aumento da carga útil e/ou vida útil dos veículos espaciais. Como conseqüência disso, a utilização dos painéis sanduíche devido a sua configuração vem crescendo nos últimos anos, pois estes painéis possuem uma relação rigidez/peso elevada. O problema abordado neste

17. Diarréia neonatal: desenvolvimento e avaliação de um método de Elisa para a detecção de rotavírus a partir de material fecal. / Neonatal diarrhea: development and evaluation of a method of ELISA for rotavírus detection from fecal material.
Rotaviruses have been identified worldwide as a major etiologic agent of acute nonbacterial diarrhea in the young of many species, including humans. In this investigation was developed and evaluated a double-sandwich antibody ELISA method for detection of rotavirus from stool specimens. For that, the NCDV strain of rotavirus group A was serially cultivat

18. Performance characteristics of recombinant enzyme immunoassay to detect antibodies to human immunodeficiency virus type 1 (HIV-1) and HIV-2 and to measure early antibody responses in seroconverting patients.
We investigated the performance of a double-antigen sandwich recombinant enzyme immunoassay (EIA; Abbott Laboratories, North Chicago, Ill.) and compared it with that of a synthetic-peptide-based EIA (Biochem Immunosystems, Montreal, Quebec, Canada) for the detection of human immunodeficiency type 1 (HIV-1) and HIV-2 antibodies in 2,321 clinical serum samples

19. Characterization of monoclonal antibodies to protein antigen of Salmonella typhi.
Two monoclonal antibodies were produced against protein antigens of Salmonella typhi. One of the antibodies (STP14) belongs to the immunoglobulin G1K subclass, and the other (STP13) was assigned to the immunoglobulin G2a(kappa) subclass. Both antibodies could recognize the 34.0-kilodalton protein antigen from S. typhi. The specificity of these antibodies was

20. Simultaneous Detection of 15 Human Cytokines in a Single Sample of Stimulated Peripheral Blood Mononuclear Cells
Cytokines secreted by cells of the immune system can alter the behavior and properties of immune or other cells. At a site of inflammation, sets of cytokines interact with immune cells, and their combined effect is often more important than the function of one isolated component. Conventional techniques, such as enzyme-linked immunosorbent assays, generally

21. Quantitation and purification of the Pasteurella multocida toxin by using monoclonal antibodies.
Pasteurella multocida toxin (PMT), derived from a toxigenic strain of P. multocida originally isolated from a pig with clinical atrophic rhinitis, was used to immunize BALB/c mice. Ninety-two hybridomas secreting monoclonal antibodies (MAbs) against PMT were produced by fusion of spleen cells from these mice with P3-X63-Ag8.653 myeloma cells. The specificity

22. Comparison of three nonradioisotopic polymerase chain reaction-based methods for detection of human immunodeficiency virus type 1.
Three nonradioisotopic polymerase chain reaction (PCR)-based detection techniques were evaluated for sensitivity and specificity in detecting human immunodeficiency virus type 1 (HIV-1) proviral DNA in peripheral blood mononuclear cells. The Roche prototype HIV-1 PCR assay, the Du Pont enzyme-linked oligonucleotide sandwich assay (ELOSA), and the Gen-Probe h

23. Monoclonal antibodies to double-stranded RNA as probes of RNA structure in crude nucleic acid extracts.
We describe four monoclonal antibodies (MAB) which specifically recognize double-stranded RNA (dsRNA) together with their use in new methods for detecting and characterizing dsRNA in unfractionated nucleic acid extracts. The specificity of the antibodies was analyzed using a panel of 27 different synthetic and naturally occurring nucleic acids. All four anti

24. Sensitive and Specific Monoclonal Antibody-Based Capture Enzyme Immunoassay for Detection of Nucleocapsid Antigen in Sera from Patients with Severe Acute Respiratory Syndrome
A rapid antigen test for the diagnosis of severe acute respiratory syndrome (SARS) is essential for control of this disease at the point of management. The nucleocapsid (N) protein of SARS-associated coronavirus (SARS-CoV) is abundantly expressed in infected-cell culture filtrate as demonstrable by Western blotting using convalescent-phase sera from patients
