25. Influência da temperatura de molde associada com o uso de fibra de vidro nas propriedades mecânicas e térmicas do nanocompósito (PA6/FV/MMT)
ABSTRACT This work describes the second of a series of studies of the effects of injection molding conditions on the mechanical and thermal properties of Polyamide 6/Glass Fiber/Montmorillonite (PA6/GF/MMT) composites and was motivated by the lack of information about how the processing variables influence on the properties of three-phase composites containi

26. Effects of avocado/soybean unsaponifiables (ASU) on the treatment of ligature-induced periodontitis in rats
Abstract The purpose of this study is to evaluate the effect of the avocado/soybean unsaponifiables (ASU) on the treatment of induced periodontitis in rats. Periodontitis was induced in 84 rats via ligature placement around the second upper molar, which was removed after 7 days, and scaling and root planning (SRP) was performed at this time. Subsequently, th

27. Relato autobiográfico para la enseñanza de la Naturaleza de la Ciencia: aproximación a la ciencia auténtica a partir de una investigación sobre el dengue
Abstract Taking as framework the importance of addressing conceptions about Nature of Science (NoS) and approaching the study of authentic science (scientific practice as is actually carried out in laboratories and other areas), we analyze the implementation of a didactic sequence using an autobiographic narration of an investigation about dengue. The proces

28. Application of Multivariate Analysis to Assess the Incorporation of Omega-3 Fatty Acid in Gluten-Free Cakes
A complete 22 experimental planning (two factors at two levels) with central point in quintuplicate was used to investigate the influence of the factors: chia and azuki flours on fatty acids composition of gluten-free chocolate cake. Both factors were significant, but chia flour presented greater influence on the results. Increased values of both factors con

29. Natural Nanotubes Reinforcing Heterophasic Polypropylene
Nanocomposites of high-impact polypropylene resin and organosilane-functionalized nanotubes in halloysite clay were prepared with the introduction of peroxide to promote selective incorporation of the filler into the polypropylene phase of the matrix, with minor insertion into the EPR elastomeric phase, thus improving the stiffness while preserving the high

30. Morphometric evaluation and planning of anticurvature filing in roots of maxillary and mandibular molars
This study aimed to guide the planning of anticurvature filing using pre-determined anatomical points on teeth to establish directions for proper implementation of the technique. Two hundred digital periapical radiographs of human molar teeth were selected and divided into two groups (n = 100): MX (maxillary) and MD (mandibular) molars. Mesiobuccal roots wer

31. Effect of scanner acoustic background noise on strict resting-state fMRI
Functional MRI (fMRI) resting-state experiments are aimed at identifying brain networks that support basal brain function. Although most investigators consider a ‘resting-state’ fMRI experiment with no specific external stimulation, subjects are unavoidably under heavy acoustic noise produced by the equipment. In the present study, we evaluated the influ

32. Modelos ridge em planejamentos de misturas: uma aplicação na extração da polpa de pequi
Mixture Models can be used in experimental situations involving areas related to food science and chemistry. Some problems of a statistical nature can be found, such as effects of multicollinearity that result in uncertainty in the optimization of a dependent variable. This study proposes the application of the ridge model adapted for mixture planning consid

34. O potencial dos espaços abertos na qualificação urbana : uma experiência piloto na Cidade Universitária Zeferino Vaz / The potencial of open spaces in the urban qualification : a design experiment at Cidade Universitária Zeferino Vaz
The present work focuses on open spaces for collective use as articulators of the shape, use and appropriation of the contemporary city. It is the continuity of a research that started in the master thesis, where the concept of the Architecture of the Boundary involved the redesign of the territories that mediate the public and the private realms. The hypoth

36. Sistemas estruturais em formato de abóbada reticulada / Structural systems with reticulated vault shape
Os sistemas estruturais em formato de abóbada reticulada são estruturas côncavas, com modulação losangular ou triangular, capazes de gerar coberturas leves, destinadas a vencer grandes vãos. Apresentam forma geométrica favorável ao recebimento e distribuição de cargas, com predominância de solicitações axiais. De notória viabilidade técnica e
