25. Clinical trial for evaluation of Ricinus communis and sodium hypochlorite as denture cleanser
Abstract The development of opportunistic infections due to poor denture hygiene conditions justified the search for effective hygiene protocols for controlling denture biofilm. Objective This study evaluated Ricinus communis and sodium hypochlorite solutions in terms of biofilm removal ability, remission of candidiasis, antimicrobial activity, and partici

26. PhotoMetrix: An Application for Univariate Calibration and Principal Components Analysis Using Colorimetry on Mobile Devices
This article describes the development of a mobile colorimetric analysis tool. The application, called PhotoMetrix, employs the techniques of simple linear correlation for univariate analysis and principal components analysis (PCA) for multivariate exploratory analysis. The image data are captured by the main camera of the device and converted into red, gree

27. Atmospheric corrosion of Nylon 6,6 in Mauritius
ABSTRACT Plastics are being more and more commonly used for outdoor applications in Mauritius. In this context, the atmospheric corrosion degradation behaviour of nylon 6,6 was observed in the Mauritian atmosphere, having a corrosivity category of C3, according to ISO 9223. The crack width, depth and extent of the cracks formed on the surface were investigat

28. Glucosamine and chondroitin sulfate association increases tibial epiphyseal growth plate proliferation and bone formation in ovariectomized rats
OBJECTIVE: The growth plate consists of organized hyaline cartilage and serves as a scaffold for endochondral ossification, a process that mediates longitudinal bone growth. Based on evidence showing that the oral administration of glucosamine sul

29. Relationship between microstructure and fracture types in a UNS S32205 duplex stainless steel
Duplex stainless steels are susceptible to the formation of sigma phase at high temperature which could potentially be responsible for catastrophic service failure of components. Thermal treatments were applied to duplex stainless steels in order to promote the precipitation of different fractions of sigma phase into a ferrite-austenite microstructure. Quant

30. Effectiveness of different obturation techniques in surpassing the ledge formed in simulated curved canals
AIM: To compare the effectiveness of different obturation techniques in surpassing the ledge formed in simulated curved root canals. METHODS: Eighty acrylic-resin blocks with curved canals were instrumented with Gates-Glidden drills to simulate a ledge formation. Then, a K-File #10 was used for trying to surpass the deviation, and the blocks that permitted s

31. Hydrogel of polysaccharide of sugarcane molasses as carrier of bone morphogenetic protein in the reconstruction of critical bone defects in rats
PURPOSE: To evaluate the benefit of using carriers such as the biopolymer gel (hidrogel of polysaccharide of sugarcane molasses) associated with the bone morphogenetic proteins (BMP's) in the repair of critical bone defects in calvaria of Wistar rats. METHODS: Forty-two rats were submitted to a surgical calvaria bone defects. These animals were divided into

32. Possibilidades de reorganização territorial apoiada na imagem náutica a partir de Angra dos Reis-RJ / Possibilities of territorial reorganization supported in nautical image based on Angra dos Reis-RJ
This thesis provides a perspective for nautical tourism as an occasion of reorganization of the territory. In order to make navigation as leisure, recreation and tourism a subject of public interest, it seeks to provide subsidies for planning schedules and raise the collective mentality to expand opportunities and benefits to the propensity of coastal boatin

33. CONFLITO GERACIONAL E A IDENTIDADE DOS JOVENS ADVENTISTAS DO SÉTIMO DIA: NEGAÇÃO OU RECONSTRUÇÃO DA IDENTIDADE ADVENTISTA POR PARTE DOS JOVENS / Gerational gap and the identidy of young seventh-day adventists ...
This present study aims to examine the generational gap and identity formation of young Adventists, in order to verify if the generational gap is a demonstration that young people are breaking with the church or, reconstructing identity. The generational gap can be seen in various spheres of society and even within the Adventist Church. However, the generati

34. Effect of ball to powder weight ratio on the mechanochemical synthesis of MoSi2-TiC nanocomposite powder
MoSi2-TiC nanocomposite powders were successfully synthesized with different ball to powder weight ratios (BPR) by ball milling of Mo, Si, Ti and graphite elemental powders. Formation of this composite was studied by X-ray diffraction (XRD). Morphology and microstructure of the milled powders were monitored by scanning and transmission electron microscopy (S

35. The influence of contact stress distribution and specific film thickness on the wear of spur gears during pitting tests
One of the main gear damage mechanisms is the formation of pitting and spalling on the tooth flank. Several factors have significant influence on the damage formation, such as: contact stress level; tooth profile type; relative contact speed; surface finish and lubrication conditions. This work comprehends the global observation of all such parameters and wa

36. Microstructural characterization of as-cast hf-b alloys
An accurate knowledge of several metal-boron phase diagrams is important to evaluation of higher order systems such as metal-silicon-boron ternaries. The refinement and reassessment of phase diagram data is a continuous work, thus the reevaluation of metal-boron systems provides the possibility to confirm previous data from an investigation using higher puri
