37. Simultaneous analysis of T helper subsets (Th1, Th2, Th9, Th17, Th22, Tfh, Tr1 and Tregs) markers expression in periapical lesions reveals multiple cytokine clusters accountable for lesions activity and inactivity status
Previous studies demonstrate that the balance between pro- and anti-inflammatory mediators determines the stable or progressive nature of periapical granulomas by modulating the balance of the osteoclastogenic factor RANKL and its antagonist OPG. However, the cytokine networks operating in the development of periapical lesions are quite more complex than wha

38. Quality evaluation of parmesan-type cheese: a chemometric approach
Parmesan-type cheeses are the most consumed special cheeses in Brazil. It is generally sold in retail shops, either grated or in wedge-shaped pieces, and its quality varies considerably, which is reflected directly in its price. There is lack of processing standardization and, since the ripening period is fundamental for the quality of this hard, semi-fat co

39. Inequidades invisibles en la educación Chilena: Brechas entre estudiantes urbanos y rurales en la Prueba PISA de Lectura (2009)
This article compares the Pisa 2009 Reading Literacy test results of urban and rural students, through a multi-level hierarchical analysis of the database variables, identifying two levels: (i) home/student and (ii) school. The main results confirm that students in rural areas have fewer opportunities than those in urban areas, which means that rural student

40. 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

41. Análise multiparamétrica da qualidade dos frutos, mostos e vinhos de jabuticaba / Multiparametric analysis of quality of fruits, musts and wines jabuticaba
Chemical parameters were monitored during the jabuticabas development, fermentation and ageing of its wine, by quantitative 1H NMR, spectrophotometric assays and standard methods of analysis. Data collected were analysed by variance (ANOVA), principal components (PCA), hierarchical cluster (HCA) and canonical correlation analyses (CCA). Jabuticabas developme

42. Adjudicação e comércio internacional - o caso dos pneus reformados / Adjudication and international trade - the case of retreaded tires
The international jurisdiction expands with the creation, from the second half of the twentieth century, of a large number of international judicial entities. Such entities are usually designed with specialization in a particular segment of international law, that somehow breaks the its unity. In parallel, the increase in the frequency of cases prosecuted be

43. Aprendizado não supervisionado de hierarquias de tópicos a partir de coleções textuais dinâmicas / Unsupervised learning of topic hierarchies from dynamic text collections
The need to extract new and useful knowledge from large textual collections has motivated researchs on Text Mining methods. Among the existing methods, initiatives for the knowledge organization by topic hierarchies are very popular. In the topic hierarchies, the knowledge is represented by topics and subtopics, and each topic contains documents of similar c

44. The relationship between manufacturing integration and performance from an activity-oriented perspective
Manufacturing integration with other functional areas and suppliers is a key aspect for achieving sustainable competitive advantage. The objective of this study is to analyze manufacturing integration from an activity-based perspective. We hypothesize that manufacturing integration with suppliers, marketing, and R&D is positively related to profit and sales

45. Aplicação de métodos quimiométricos na caracterização de charutos utilizando extração por dispersão da matriz em fase sólida e análise por cromatografia gasosa acoplada à espectrometria de massas
In this work, the organic compounds of cigar samples from different brands were analyzed. The compound extraction was made using the matrix solid-phase dispersion (MSPD) technique, followed by gas chromatography and identification by mass spectrometry (GC-MS) and standards, when available. Thirty eight organic compounds were found in seven different brands.

47. High-order unstructured spectral finite volume method for aerodynamic applications.
An implicit finite volume algorithm is developed for higher-order unstructured computation of inviscid compressible flows. The Spectral Finite Volume method is used to achieve high-order spatial discretization of the domain, coupled with a matrix-free LU-SGS algorithm to solve the linear systems arising from implicit time marching of the governing equations,
