Investigação da Interface Metal-Porcelana da Liga Ni-Cr-Mo Soldada a LASER

The interface formed between the metal and the porcelain of a LASER welded Ni-Cr-Mo alloy was studied. The characterization was carried out through optical microscopy, scanning electron microscopy, X-ray dispersive spectroscopy-EDS and mechanical testing by three-point flexion test-TPE in the region LASER welded with and without the porcelain. The porcelain adhesion with the alloy alone is possible after the oxidation of the metallic surface and subsequent application of an adhesive called opaco. The applied porcelain, on the base metal and fusion zone presented some distinct behaviors. After the TPF test the base metal presented fractures while that in the fusion zone was completely gone. One noticed that the region submitted to the LASER welding showed less porcelain adhesion than the region of the base metal due to the microestructural refinement of the fusion zone. These results can be evidenced by the EDS of the studied regions. The TPF had demonstrated that the Ni-Cr-Mo alloy submitted to the LASER welding, undergone significant alterations in its mechanical properties after the application of the porcelain.

Uma investigação antropológica na terceira idade: concepções sobre a hipertensão arterial

Essa pesquisa teve por objetivos: a) identificar as concepções da população idosa do município de Araraquara, SP, quanto à etiologia da hipertensão arterial e a relevância dos diferentes sinais e sintomas que acompanham a doença; b) identificar as concepções dos idosos relativas à relevância e à utilização das diferentes categorias de tratamento para HA. Foram realizadas entrevistas estruturadas com 29 indivíduos, a maioria com 60 anos ou mais, em tratamento de hipertensão em ambulatório de gerontologia da Prefeitura do Município de Araraquara, em agosto de 1996. Os pacientes encontram-se bem informados pela equipe de saúde sobre os problemas relacionados à hipertensão arterial. Concepções de etiologia tipicamente populares também apareceram, tratando-se de aspectos que devem ser considerados quando da realização de ações de educação em saúde. O atendimento por uma equipe multidisciplinar é valorizado pelos idosos, e a reclamação mais freqüente refere-se à falta dos medicamentos prescritos para entrega gratuita no ambulatório. Para melhorar a comunicação entre equipe de saúde e pacientes é importante a inclusão de profissionais do campo das ciências humanas nas equipes gerontológicas.

Avaliação da qualidade da assistência no programa de AIDS: questões para a investigação em serviços de saúde no Brasil

O artigo mostra o desenvolvimento de uma pesquisa que objetivou avaliar a qualidade da assistência ambulatorial do Programa Brasileiro de DST/ AIDS. A investigação, realizada entre 2001-2003, envolveu três projetos: uma análise do padrão tecnológico da assistência realizada em cinco serviços, uma avaliação qualitativa em 27 serviços e, finalmente, uma avaliação estruturada de 322 serviços de sete estados brasileiros. Mediante a descrição de todas as etapas dos projetos, as autoras discutem questões teóricas e metodológicas envolvidas na avaliação da assistência em programas de saúde. Discutem ainda algumas questões relacionadas à aplicabilidade e ao impacto das avaliações em serviços de saúde.

Investigação de parasitoses e/ou comensais intestinais em manipuladores de alimentos de escolas públicas

The objective of this work was to identify intestinal parasites and/or commensals among food handlers of public schools in the city of Patos of Minas (MG). The fecal samples were analyzed by Lutz's method (1919). The positive results were 21.7% (13 cases) for parasites and/or commensal. The frequence of intestinal parasites and/or commensal of food handlers in the public schools showed low positive, probably as a result of good habits of personal hygiene and prophylactic treatment of parasitic.

Investigação de Intrusão de Água Salgada em Aqüífero Superficial a Partir de Medidas de Resistividade Elétrica

A site investigation program was carried out to detect salt-water intrusions in a shallow sedimentary aquifer based on electrical resistivity measurements. The site is located close to Paranaguá harbor, in the Paraná State, Brasil. At this site, high chloride concentration contaminated shallow water wells used to supply water for local industries. The site investigation program included a fieldwork, dipole-dipole electrical profiling, resistivity piezocone tests, physical-chemical analysis of sampled water and interpretation of borehole logs. The resistivity piezocone tests provided two simultaneous information; the soil stratigraphy at a very detailed level and a quasi-continuous resistivity profile. Both information adequately complemented dipole-dipole electrical profiling test data. The integration of all test data allowed identifying the contaminated areas as well as guided the location of new water wells to be installed in this area.

Técnica autorradiográfica para investigação geológica - Estudo de caso na área do projeto rio preto

The auto-radiography is a photographic method to registrate in sensitive emulsion the spatial distribution a rays emitted by radioisotopes of a sample or an object. The auto-radiography was applied to detect the presence of radioactive minerals in some samples of schists and gneisses from the Ticunzal Formation, Northeast Goiás State, aiming to implement the use of this technique in LABIDRO - Hydrochemistry and Isotopes Laboratory of the Department of Petrology and Metallogenesis, State University of São Paulo/Campus of Rio Claro.

Investigação soroepidemiológica de leptospirose canina na área territorial urbana de Botucatu, São Paulo, Brasil

Leptospirosis was seroepidemiologically investigated in 775 dogs from Botucatu, state of Sao Paulo, in blood samples collected during the annual anti-rabies vaccination campaign. The samples were collected from 14 out of the 45 vaccination stations geographically distributed in five different municipal districts, with a territorial urban area of 31Km2. Samples were taken from 449 males and 326 females; 564 were of undetermined breed, and 211 were pedigree animals; ages ranged from 3 months to 20 years. Diagnosis included the microscopic serum agglutination tests using 12 Leptospira spp serovars. Serological results and epidemiological variables were compared using Goodman and chi-square tests, with χ=0.05. There were 119 (15.3%) positive samples for 11 serovars; the most important was canicola with 48 (40.3%), followed by pyrogenes 41 (34.5%). Statistical analysis showed significant difference for: breed, 17.7% positive in undetermined breeds and 9.0% in pedigrees; and sex, 18.4% positive in males and 11.0% in females. There was no statistically significant difference in relation to age with uniform distribution of positives.

Fluorescência da clorofila-a e variação da simetria como ferramentas de investigação de plantas sob estresse

Environmental disturbances in various systems and individuals can result in a tendency for fluctuating asymmetry, which consists of a non-directional deviation from symmetry of a bilateral structure in a normally distributed population. Individuals unable to exhibit plastic responses to developmental disorders that occur at random, either genetic or environmental, may exhibit slight deviations from symmetry in organs with bilateral structure such as leaves. Thus analyzing plants by the morphological pattern of symmetry of the leaves has become an effective tool to describe the developmental of plants under stress conditions. This study aimed to analyze if the pattern of symmetry can be used as a tool to investigate the stress level to which a plant is subjected, using ultraviolet-C radiation (UV-C) as source of stress. We determined the leaf symmetry deviations (sd), the average length (AL) and the maximum width of the lamina (MWL) and the fluorescence parameters of chlorophyll-a in leaves of young plants of G. max subjected to 0, 30, 60, 120 or 240 minutes per week of UV-C during four weeks, submitting the values to ANOVA and Tukey test (p <0.05). The results showed significant reductions in AL and MWL, significant increase in sd in leaves irradiated and a drop in potential quantum yield of photosystem II (PSII) and in the photosynthesis performance index (IP). The analysis of leaf symmetry showed high correlation with the stress level to which plants were submitted, being an important analysis to ascertain the fitness of the plant because it is a noninvasive method and easy to perform.

Investigação tecnológica de arenitos silicificados da Formação Botucatu (ne do Paraná) para uso como rocha de revestimento

For many years the silicified sandstone associated of the Botucatu Formation has been the target of interest to researchers and miners, either for understanding the genesis of silicification or for your use as dimension stone and covering on the building industry. If in the first there are several articles available in the geological literature the second there are only technical data marketing available. In the northeast portion of the Paraná State and southwest of the São Paulo State these rocks are mined and traded as covering stones. Not much is known about their intrinsic characteristics and technological properties. To improve the knowledge of the technological behavior of these materials, samples from a quarry from Ribeirao Claro region were petrographically and physically characterized according to the standards established by the Brazilian Association of Technical Standards to dimension stones. Therefore, two bulk samples of silicified sandstone of the Ribeirão Claro/PR region were studied and characterized following the norms established by Brazilian Association of Technical Standards for dimension stones. The results obtained in the petrographical and technological studies are presented and indicated that, in general, the technological performance presented by sandstone studied induces limitations of use as covering materials, mainly horizontally as pavements, door stone and step ladder.
