MALBOUISSON Luiz Marcelo Sá,PERES Denise,AYAMA Sérgio,CARMONA Maria José Carvalho
Revista Brasileira de Cirurgia Cardiovascular , 2001,
Abstract: A associa o de paralisia diafragmática bilateral e paralisia da cintura escapular é uma complica o rara após corre o de aneurisma de aorta ascendente. Esta associa o leva à uma forma grave de insuficiência respiratória cujo sucesso do desmame da ventila o mecanica é dependente da capacidade da musculatura respiratória remanescente em compensar o trabalho respiratório excedente. Fisioterapia respiratória intensiva com treinamento da musculatura, corre o dos distúrbios metabólicos, tratamento das infec es respiratórias associadas à ventila o mecanica e otimiza o do suporte nutricional foram fundamentais para o sucesso do desmame.

Revista Paulista de Pediatria , 2012, DOI: 10.1590/s0103-05822012000300004
Abstract: OBJETIVO: Analisar a avalia o da saúde de crian as de creches públicas e privadas de uma cidade do Sul do Brasil feita por seus responsáveis e investigar sua associa o com fatores socioecon micos, demográficos e aqueles relacionados ao estado de saúde. MéTODOS: Estudo transversal com amostragem em duplo estágio (n=589). A coleta de dados incluiu medidas antropométricas e questionário com variáveis infantis e do responsável. A avalia o do responsável sobre a saúde infantil foi coletada como muito boa, boa, regular, ruim ou muito ruim. Para a análise, as duas primeiras categorias foram agrupadas e as três últimas indicaram saúde negativa. As raz es de prevalência brutas e ajustadas e seus respectivos intervalos de confian a de 95% (IC95%) foram calculadas por meio da regress o de Poisson, com ajuste para delineamentos complexos. RESULTADOS: Foram avaliadas 531 crian as (90,2%) com idades de 1,5 meses a 7,5 anos, a maioria de creches públicas (75,9%). Apenas 8,1% (IC95% 5,8 - 10,4) tiveram sua saúde classificada como regular. Crian as hospitalizadas no ano anterior, as de ra a negra, amarela ou indígenas, que ficavam mais de 20 horas por semana na creche e com consumo alimentar considerado "pequeno" pelos pais apresentaram maior prevalência de saúde classificada como regular. Pais que relataram consumir bebidas alcoólicas avaliaram como pior a saúde de seus filhos. CONCLUS ES: A maioria dos responsáveis avaliou positivamente a saúde de seus filhos. Cor da pele, hospitaliza es e consumo alimentar foram variáveis independentemente associadas à pior avalia o de saúde infantil pelos responsáveis.

Model of Three-Phase Transmission Line with the Theory of Modal Decomposition Implied  [PDF]
Rodrigo Cleber da Silva, Sérgio Kurokawa
Energy and Power Engineering (EPE) , 2013, DOI: 10.4236/epe.2013.54B217
Abstract:

This paper shows the development of transmission line model, based on lumped element circuit that provides answers directly in the time and phase domain. This model is valid to represent the ideally transposed line, the phases of each of the small line segments are separated in their modes of propagation and the voltage and current are calculated at the modal domain. However, the conversion phase-mode-phase is inserted in the state equations which describe the currents and voltages along the line of which there is no need to know the user of the model representation of the theory in the line modal domain.

Influence of Phosphoric Acid Etching on the Bond Strength of a Universal Adhesive System to Caries-Affected Dentin  [PDF]
Renata Pavanello, Sérgio Luiz Pinheiro
Advances in Biological Chemistry (ABC) , 2018, DOI: 10.4236/abc.2018.83004
Abstract: The purpose of this study was to evaluate the influence of acid etching on the bond strength of a universal adhesive system (Single Bond Universal, 3M) to caries-affected dentin. Forty permanent third molars were selected and carious lesions were induced by the microbiological method with?S. mutans?ATCC25175. Teeth were allocated randomly across four experimental designs (n=10): PA-I: phosphoric acid etching and application of the adhesive system, followed by immediate microtensile bond strength testing; PA-CC: phosphoric acid etching and application of the adhesive system, followed by microtensile bond strength testing after a 14-day cariogenic challenge; NPA-I: application of the adhesive system without acid etching, followed by immediate bond strength testing and NPA-CC: application of the adhesive system without acid etching followed by bond strength testing after 14-day cariogenic challenge. For microtensile bond strength testing,a restoration with Charisma composite resin was made and each specimen was sectioned with a cross-sectional area of 1 mm2. Only adhesive and mixed fractures were considered for bond strength calculation. Results were evaluated by the Kruskal-Wallis and Friedman tests. The highest bond strengths were observed in the phosphoric acid etching groups (p<0.05). Cariogenic challenge did not affect bond strength (p>0.05). The predominant fracture type was adhesive. We conclude that phosphoric acid increased the bond strength of the Single Bond Universal system to caries-affected dentin, and
Sombras como indicadores da percep??o de profundidade
Fukusima, Sérgio S.;
Psicologia: Reflex?o e Crítica , 1997, DOI: 10.1590/S0102-79721997000200008
Abstract: the cast shadow of a flat square was depicted on a computer screen by orthografic projection, and investigated as a perceived depth cue. the shadow was projected to five positions relative to the incidence of the light in each quadrant of the screen. five adults participated in the experiment. results indicated that the magnitude of the depth estimates increased as a function of the exposed shadow area when the same was partially ocluded. in the conditions in which the shadow was not ocluded, perceptual and cognitive factor can bias the depth estimates.
Sombras como indicadores da percep o de profundidade
Fukusima Sérgio S.
Psicologia: Reflex?o e Crítica , 1997,
Abstract: A sombra de um quadrado projetada ortograficamente sobre uma superfície plana foi investigada como indicadora de profundidade percebida. A sombra foi simulada por computador em cinco posi es, relativas ao angulo de incidência da luz, em cada quadrante da tela do monitor. Os resultados indicaram que as magnitudes das estimativas de profundidade aumentam em fun o da área exposta da sombra nos casos em que a mesma é parcialmente ocluída. No caso em que a sombra n o é ocluída, fatores perceptivos e cognitivos podem afetar as estimativas de profundidade.
Feedback boundary stabilization to trajectories for 3D Navier-Stokes equations
Sérgio S. Rodrigues
Mathematics , 2015,
Abstract: Given a nonstationary trajectory of the Navier-Stokes system, a finite-dimensional feedback boundary controller stabilizing locally the system to the given trajectory is derived. Moreover the controller is supported in a given open subset of the boundary of the domain containing the fluid. In a first step a controller is derived that stabilizes the linear Oseen-Stokes system "around the given trajectory" to zero; for that a corollary of a suitable truncated boundary observability inequality, the regularizing property for the system, and some standard techniques of the optimal control theory are used. Then it is shown that the same controller also stabilizes, locally, the Navier-Stokes system to the given trajectory.
Fever and Infection Prevalence in Hematology-Oncology Hospitalized Patients: A Single-Center Retrospective Study  [PDF]
Inês Almeida Costa, Sérgio Chacim, José Mariz
Journal of Cancer Therapy (JCT) , 2018, DOI: 10.4236/jct.2018.93020
Abstract: Fever is prevalent in hospitalized patients. In hematology-oncology patients, it is related with infection, a disease manifestation or a consequence of immunological dysfunction. This single-center retrospective study aims to determine fever prevalence, describe its causes and evaluate the impact of infection on mortality. We reviewed clinical records of 222 patients admitted to the hospital in three random months of 2015. Around 35% of all hospitalizations were complicated by fever, 42.5% of unknown origin. 90.4% were under treatment. Around 81% did antibiotics, most commonly piperacillin/tazobactam, for around 11 days. 41% changed antibiotics due to fever persistence or microbiological results. The diagnostic yield of microbiological tests was 25%; in 66.7%, a Gram-negative microorganism was isolated. We didn’t find an association between infection and mortality. We conclude that fever is common in our hematology-oncology clinic and that the team is trained to assume infection; empirical treatment is in accordance with international recommendations.
