The smallest known three-dimensional closed manifold of curvature k = -1 was discovered a few years ago by Weeks. This kind of manifold is constructed from a hyperbolic polyhedron with faces pair-wise identified. Here it is used as the comoving spatial section of a Friedmann cosmological model, in the spirit of Ellis and Schreiber's idea of small universes. Its nontrivial global topology has the effect of producing multiple images of single cosmic sources, and this is the basis of an attempt to solve a famous controversy about the redshifts of quasars.

We propose a modified form of the spontaneous birth of the universe by quantum tunneling. It proceeds through topology change and inflation, to eventually become a universe with closed spatial sections of negative spatial curvature and nontrivial global topology.

We clarify and develop the results of a previous paper on the birth of a closed universe of negative spatial curvature and multiply connected topology. In particular we discuss the initial instanton and the second topology change in more detail, This is followed by a short discussion of the results.

To investigate the relationship of dyslipidemia with demographic distribution and patterns of body fat and dietary intakes. From a universe of adults clinically selected for a lifestyle modification program 979 subjects (409 males and 570 females, 52.2 +/- 9.6 years) fulfilled the inclusion criteria. Overnight-fasting plasma was assayed (dry chemistry) for triglycerides (TG), total (TC) and HDL fraction of cholesterol given the non-HDL (n-HDL) fraction by the difference. Anthropometric assessment included body weight (kg), height (m), fat (bioelectrical impedance) and waist circumference (WC). Food intake was assessed by the 24-hour recall questionnaire and the food groups evaluated through recommendations from an adapted food pyramid. The chances of dyslipidemia from other variable changes were determined by logistic regression with p < 0.05. Normal values of BMI and WC were protective against all dyslipidemia markers whereas only hypercholesterolemia was influenced by diet (meat intake > 2 servings). Dietary intakes have protective effects against hypertriglyceridemia with whole grains, odds ratio (OR) 0.342 (Cl 95%, 0.154-0.760), fruits >= 3 servings (OR 0.523, 0.290-0.941) and vegetables >= 4 servings (OR 0.360, 0.176-0.735). In general total body and abdominal adiposity influenced all dystipidemia markers while dietary intake of fruits and vegetables protected against triglyceridemia.

A few years ago, Cornish, Spergel and Starkman (CSS) suggested that a multiply connected small universe could allow for classical chaotic mixing as a preinflationary homogenization process. The smaller the volume, the more important the process. Also, a smaller universe has a greater probability of being spontaneously created. Previously DeWitt, Hart and Isham (DHI) calculated the Casimir energy for static multiply connected fat space-times. Because of the interest in small volume hyperbolic universes (e.g., CSS), we generalize the DHI calculation by making a numerical investigation of the Casimir energy for a conformally coupled, massive scalar field in a static universe, whose spatial sections are the Weeks manifold, the smallest universe of negative curvature known. In spite of being a numerical calculation, our result is in fact exact. It is shown that there is spontaneous vacuum excitation of low multipolar components.

This paper investigates, in light of the theory of Functional Discourse Grammar (HENGEVELD; MACKENZIE, 2008), the concessive clause that is not subordinated to other clauses, i.e., it has no semantic or syntactic relations with clauses before or after it, and which we call Independent Concessive. The aim is to describe the discursive properties and the semantic, morphosyntactic and prosodic structure of this type of clause, showing that its relevance is in the construction and organization of discourse. The results indicate that the Independent Concessive works in speech as a parenthesis which interrupts the discursive course and is then highlighted by a special prosodic contour, combined with the presence of Interactive Acts. It is therefore a Move, the highest layer of the Interpersonal Level, the level that relates to the pragmatic aspects of the grammar of a language. The universe of research used is the Iboruna corpus, a database that records a variety of Portuguese from the Northwest of São Paulo.

This final project intends to discourse about the cinematographic publicity piece that is the trailer and its main features. Its relation with the publicity is studied so we can understand how this relation occurs, once the trailer is found in between the cinema and the publicity. The trailer features are exposed, such as the persuasive features, so it becomes evident the importance of studying this advertising tool from a broad perspective. In addition, we seek to determine its aesthetics, its compositional characteristics and their relevance in movie marketing. The paper discusses briefly about the universe of the movie marketing, as a way of situating the trailer as a tool in a set of publicity techniques that help in selling movies. A case study is conducted, involving the analysis of 5 trailers from different categories of gender, in order to capture the essence of the overall trailer, such from the persuasive perspective as the audiovisual perspective. Finally the is the addition of a current universe of characteristics that can be found in the contemporary trailers, grounded by theorists and film scholars that accompanied the evolution of this advertising tool
