1. Chlorhexidine with or without alcohol against biofilm formation: efficacy, adverse events and taste preference
Abstract In recent years, different chlorhexidine formulations have been tested, including an alcohol-free alternative, but the effect of this solution on early biofilm formation is not clear. A crossover, randomized, double-blind clinical trial was conducted to evaluate the effect of two chlorhexidine solutions against supra- and subgingival biofilm formati

2. Intra-radicular dentin treatments and retention of fiber posts with self-adhesive resin cements
The aim of this study was to evaluate the effect of treating intraradicular dentin with irrigating solutions on the retention of glass-fiber posts luted with self-adhesive resin cement. Bovine incisors were endodontically treated, and 9-mm-deep postholes were prepared. Before inserting the cement, the root canals were irrigated with various solutions: 11.5%

3. Obtenção e caracterização de frações purificadas de saponinas de chenopodium quinoa e avaliação da formação de complexos do tipo iscom : atividades biológicas das frações e dos complexos formados
Chenopodium quinoa (quinoa) seeds are a rich protein source and well-known for their high saponin content. Chemically, quinoa saponins are triterpene glycosides being phytolaccagenic, hederagenin, oleanolic and serjanic acids the most common aglycones found in seeds. Its immunoadjuvant properties have been examined and the results obtained were conflicting.

4. Kinematic self-similar solutions of locally rotationally symmetric spacetimes
This paper contains locally rotationally symmetric kinematic self-similar perfect fluid and dust solutions. We consider three families of metrics which admit kinematic self-similar vectors of the first, second, zeroth and infinite kinds, not only for the tilted fluid case but also for the parallel and orthogonal cases. It is found that the orthogonal case gi

5. Housing project to slums: specificities and quality parameters / Projeto de habitação em favelas: especificidades e parâmetros de qualidade
This thesis proposes a method for the development of housing units addressed to slums upgrading programs, aiming to improve the built environment in these areas. It was composed based on the housing dynamics of Sao Paulo that led to the emergence of slums, one of the main housing alternatives for low-income people in this city. The proposed method considers

6. Lie symmetries and related group-invariant solutions of a nonlinear Fokker-Planck equation based on the Sharma-Taneja-Mittal entropy
In the framework of the statistical mechanics based on the Sharma-Taneja-Mittal entropy we derive a family of nonlinear Fokker-Planck equations characterized by the associated non-increasing Lyapunov functional. This class of equations describes kinetic processes in anomalous mediums where both super-diffusive and subdiffusive mechanisms arise contemporarily

7. Processos litográficos em filmes epitaxiais de compostos IV-VI para medidas Hall e o estudo da dopagem do telureto de chumbo com flureto de bário / Lithographic processes in epitaxial films of IV-VI compounds for Hall measurements and the study of lead telluride doping with barium flouride
The first part of the work dealt with the application of lithographical techniques to fabricate Hall geometry of IV-VI films grown on (111) BaF_2 substrates. A previous study of In diffusion in PbTe films confirmed the viability of using In as a metallic contact. During the lithographic process, some solutions were implemented to resolve the problems generat

8. SoluÃÃes auto - similares e comportamento assintÃtico para as equaÃÃes de navier - Stokes
This master dissertation deals with the Navier-Stokes s equations on Rm, assuming that the fluid is incompressible and homogeneous. We analyzed the Cauchy s problem in Marcinkiewicz spaces (L p−weak), with the right index to allow the existence of selfsimilar solutions. We also study the asymptotic behavior of the solutions and show the existence of a

9. Auto-similaridade e unicidade para um sistema semilinear e existÃncia de soluÃÃo com dado singular para a equaÃÃo da onda semilinear
We obtain well-posedeness of small global solutions in Marcinkiewicz spaces L(p1,∞) x L(p2,∞) for semilinear systems. Mild solutions are obtained in this space with the right index to allow the existence of self-similar solutions. Using our estimates of the nonlinear coupling term, we prove the uniqueness of solutions in the class C([0,∞);L

10. Busca e recuperaÃÃo de componentes de software utilizando agrupamento de componentes
The development of software with reuse is an approach that can be used to achieve two main benefits: (1) increase in productivity of software projects and (2) improvements in the final quality of the products. The software reuse approach can be instantiated through the strategy of development based in software components. According to this strategy, large so

11. Caracterização óptica de dispersões aquosas de nanotubos de carbono
It has been demonstrated that the electronic and optical properties of single-wall carbon nanotubes (SWNT) are strongly affected by the environment. This strong environmental effect is very relevant in analyzing the composition of carbon nanotube samples using optical techniques, especially in the case of separation experiments, where the SWNT environments a

12. Um guia para criação de modelos de desenho de software no Praxis Synergia
Model Driven Development is a software engineering process based on systems domain modeling. Each unsuccessful software project has it s own unique failure causes, but all successful projects are similar at all. There are many elements that make a well done project; one of them is modeling. Right chosen models have huge influence on how problems are treated
