Generalized Integral Transform Solution for hydrodynamically developing non-Newtonian flows in circular tubes
Nascimento, Shirley C. C.;Macêdo, Emanuel N.;Quaresma, Joo N. N.;
Journal of the Brazilian Society of Mechanical Sciences and Engineering , 2006, DOI: 10.1590/S1678-58782006000100015
Abstract: the generalized integral transform technique (gitt) is applied to the solution of the momentum equations in a hydrodynamically developing laminar flow of a non-newtonian power-law fluid inside a circular duct. a primitive variables formulation is adopted in order to avoid the singularity of the auxiliary eigenvalue problem in terms of bessel functions at the centerline of the duct when the gitt approach is applied. results for the velocity field and friction factor-reynolds number product are computed for different power-law indices, which are tabulated and graphically presented as functions of the dimensionless coordinates. critical comparisons with previous results in the literature are also performed, in order to validate the numerical codes developed in the present work and to demonstrate the consistency of the final results.

International Journal of Morphology , 2009, DOI: 10.4067/S0717-95022009000100028
Abstract: the aim of this study was to evaluate some biological characteristics and toxicity of basic formulations of dentifrices containing such substances, and to compare them with two existing products in market which also contains silic in their formulations. in this way, it was evaluated some biological parameters: weight of the animals, oral toxicity, hematological parameters, urinary analysis, and histological evaluation. the thrombocytes were also statistically at normal levels. the glutamate-pyruvate transaminase (tgp) showed normal aspect in 5 of the tested groups, as in control. meanwhile, the oxalacetic transaminase (ast) in one group had a small increase in the control group. regarding urine, in exception the rats of one group, the rats of the 4 other experimental groups showed leukocytosis urinary statistically higher than the control group. the histological evaluation of the animals showed that specimens from liver, stomach, kidney and submandibular gland presented normal aspects for these organs, without significant characteristics related to inflammatory infiltrates in any of the 6 samples tested in their respective groups.

Abstract: the periimplantitis term is characterized as a disease that affects the support implant tissues. it has a multifactorial etiology, with an important role of the biofilm on the periodontal diseases. the culture techniques use possibilited to identify bacterias responsible for periodontal alterations, as fusobacterium, prevotella and porphyromonas ssp. the development of the molecular biology techniques possibilited the identification of some bacterial species, that there were not related in the literature and there were responsible for periodontal pathogenesis. the microbiota present on the periodontal pockets in overdentures may contribute in the orientation of the therapeutic procedures, considering that the structural alterations on the periodontal tissues are straightly related to microorganism presence, and it constitutes one of the causes that affect the oral rehabilitation treatment with implants. this, the aim of this study was to present a literature review of dna-dna hybridization technique in the identification of the microorganisms more related to periimplantitis.
Optical Densitometry Study of the Newly Formed Bone Using rhBMP-2 in Wistar Rat Mandibles Estudio Densitométrico del Tejido óseo Neoformado por el Uso de rhBMP-2 en Mandíbulas de Ratas Wistar

Abstract: The purpose of this study was to evaluate the efficacy of monoolein gel as a carrier for rhBMP-2 in the healing bone process of critical bone defects created in Wistar rats mandibles using digitalized radiographic method to analyze this process. In the group 1, the rhBMP-2 was dissolved in aqueous solution and in the group 2, the rhBMP-2 was combined with monoolein gel as a carrier. The results showed that in both of groups it was found efficient bone repair, with a great optical density in the group that the rhBMP-2 was combined with the monoolein gel, but without statistical difference between them El objetivo de este estudio fue evaluar la eficiencia del gel de monoolein como portador de la rhBMP-2 en el proceso de recuperación de la osificación en defectos osteos creados en mandíbulas de ratos Wistar, por medio de radiografias digitalizadas como método de análisis. En el grupo 1, la rhBMP-2 fue disuelta en solución acuosa y en el grupo 2, la rhBMP-2 fue combinada al gel de monoolein como portador. Los resultados mostraron que los dos grupos presentaron un eficiente reparo osteo, con mayor densidad óptica en el grupo en que la rhBMP-2 fue combinada con el gel de monoolein, pero sin diferencia estadística significante entre ellos

El objetivo del estudio fue evaluar algunas características biológicas y de toxicidad provenientes de las formulaciones básicas de dentífricos que contienen sílice en su composición y compararlos con dos dentífricos disponibles comercialmente que también presentan sílice. El análisis hematológico no mostró diferencias entre los grupos evaluados. Los niveles de trombocitos presentados por los grupos fueron también normales. La transaminasa gluámico pirúbica se mostró un aspecto normal en 5 de los grupos estudiados, así como en el grupo control. La transaminasa glutámico oxaloacética en uno de los grupos tuvo un peque o incremento. En relación a la orina, 4 grupos presentaron leucocitosis urinaria significativamente mayor que el grupo de control. La evaluación histológica del hígado, estómago, ri ones y glándulas submandibulares se presentó con aspecto normal, sin presencia de infiltrado inflamatorio.
