1. Efeitos da exposição crônica à poluição atmosférica particulada sobre o desenvolvimento embrionário pré-implantacional in vitro em camundongos / Effects of chronic exposure to particulate air pollution on in vitro preimplantation embryo development in mice
A thematic research project to evaluate the health effects of acute/chronic exposure to ambient air in a large urban center was developed at the Air Pollution Laboratory in the Department of Pathology at the University of São Paulo School of Medicine. Within this project a specific research line was committed to the study of the effects of this exposure on

2. Effect of air-oxygen and argon-oxygen mixtures on dielectric barrier discharge decomposition of toluene
One alternative application in the decomposition and destruction of volatile organic compounds (VOCs) by a silent plasma dielectric barrier discharge (DBD) has been successfully accomplished. For this purpose, we have designed and constructed two pairs of cells, of rectangular and circular geometries, 333.96 cm³ each cell, and a similar second pair of 62.25

3. Dynamic EDCF parameters for QoS control in IEEE 802.11 hot spots
This paper describes a control mechanism for dynamic selection of Quality of Service (QoS) parameters used in a IEEE 802.11e Wireless Local Area Network (WLAN). The 802.11e specification, still under development, provides a new contention-based access method, called Enhanced Distributed Coordination Function (EDCF). This method uses distinct values for inter

4. Um metodo de analise e especificacao de sistmas com requisitos de desempenho, custo e confiabilidade, aplicado a rodas de reacao / A method for systems analysis and specification with performance, cost and reliability requirements apllied to the design of a reaction wheel
In the past, space design activities commonly emphasized mainly the system requirements. The available methods focused on functional aspects only. The cost was estimated at the end of the process. Recently, new design methodologies have been proposed. Among them, the design-to-cost (DTC) method was developed to include the cost as a parameter. In this work,

5. Desenvolvimento de técnicas de problemas inversos em convecção de calor / Developing of inverse problems techniques in convection
Nesse trabalho apresenta-se a estimação do fluxo de calor imposto em uma placa plana vertical aquecida através de medições de temperatura no interior do fluido. O problema de convecção é descrito pelas equações da energia, quantidade de movimento e da continuidade. A solução direta dessas equações é obtida analiticamente através do método de

6. High-throughput functional screen of mouse gastrula cDNA libraries reveals new components of endoderm and mesoderm specification
This study describes a cross-species functional screen of mouse gastrula cDNA libraries for components of endoderm and mesoderm specification. Pools of 96 cDNAs from arrayed mouse gastrula cDNA libraries were transcribed into mRNA and injected into either the presumptive mesoderm or the ectoderm of one-cell Xenopus laevis embryos. Injected embryos were exami

7. A computer graphics program system for protein structure representation.
We have developed a computer graphics program system for the schematic representation of several protein secondary structure analysis algorithms. The programs calculate the probability of occurrence of alpha-helix, beta-sheet and beta-turns by the method of Chou and Fasman and assign unique predicted structure to each residue using a novel conflict resolutio

8. Expectations among the elderly about nursing home entry.
OBJECTIVE: To assess whether the covariates that explain expectations of nursing home entry are consistent with the characteristics of those who enter nursing homes. DATA SOURCES: Waves 1 and 2 of the Assets and Health Dynamics Among the Oldest Old (AHEAD) survey. STUDY DESIGN: We model expectations about nursing home entry as a function of expectations abou

9. Specification and quantitation of circulating immune complexes in the serum of patients with active pulmonary sarcoidosis.
BACKGROUND--Circulating immune complexes can be elevated in serum samples of patients with sarcoidosis and are associated with disease activity, but their diagnostic significance is not understood. METHODS--The different classes of circulating immune complexes containing immunoglobulin A, G, or M, and the content of complement in circulating immune complexes
