1. Hankel transformation method for solving the Westergaard problem for point, line and distributed loads on elastic half-space
Abstract The Hankel transformation method was used in this work to determine the normal and shear stress distributions due to point, line and distributed loads applied to the surface of an elastic media. The elastic media considered in this study was assumed to be inextensible in the horizontal directions, and the only non-vanishing displacement component is

2. Stability of concrete beam-columns under follower forces
An axial follower force acting on the free end of a beam-column is known to remain tangential to its elastica at that point. Elastic beam-columns exhibit infinitely high buckling resistance to static compressive follower load. Loss of their dynamic stability is known to occur at critical follower loads, by flutter characterized by vanishing lateral displacem

3. O resto do sertão : faces da modernidade em Grande Sertão : veredas / Remnant of the sertão : faces of modernity in Grande Sertão : veredas
This thesis deals with the nexus between literary form and politics in the novel Grande sertão: veredas, by Guimarães Rosa. We take as a fundamental premise the idea that Guimarães Rosa s text operates the apprehension of a specific political modus operandi: namely, the modernization process. This can be understood under two perspectives: a horizontal one

4. Método de extração da posição de máquinas agrícolas por visão computacional baseado em redes pulsadas e ponto de fuga / Method for position extraction of agricultural machine based on pulsed neural networks and vanishing point
Cost reduction and productive process improvement are essential to increase yield in agricultural areas. Investments in technology become, therefore, important in a competitive world. This work presents a novel approach for extracting agricultural machine position, with respect to crop rows, processing images captured by a color video camera. The correct mac

5. A local non-Abelian gauge invariant action stemming from the nonlocal operator FmuN(D²)-1FmuN
We report on the nonlocal gauge invariant operator of dimension two, FµN (D²)-1 FµN. We are able to localize this operator by introducing a suitable set of (anti)commuting antisymmetric tensor fields. Starting from this, we succeed in constructing a local gauge invariant action containing a mass parameter, and we prove the renormalizability to all orders

6. Nas fronteiras da memória: Guimarães Rosa e Mia Couto, olhares que se cruzam / In the borders of the memory: Guimarães Rosa and Mia Couto, look cross
This work makes a comparison among the workmanships of João Guimarães Rosa and Mia Couto, contemplating the similarities and differences between its aesthetic projects, having as conducting wire the verbal tradition. According to Walter Benjamin, all the great writers exhausted the verbal tradition and, Ángel Rama seems to corroborate with this, when he s

7. Molduras para o vazio : duas obras de Clarice Lispector
This text analyzes some variations of the impasse outlined in Lispector s first novel, Perto do coração selvagem, which leaves its trace when examining A paixão segundo G.H. and A hora da estrela. Since the first novel, it is possible to state the division of the characters, the division of the narrators, and the division of the texts between ?living? and

8. No limiar do silêncio e da letra: traços da autoria em Clarice Lispector / On the threshold of silence and letter: traces of authorship in Clarice Lispector
The field of literature is the field of mimesis. So that it occurs, an object suitable for depiction, a subject that performs it and a language that makes it viable as well as a reader to receive it are imperative. The object to be re-created can be real or virtual and the means for its re-creation is the word. Words aimed at reaching beyond the threshold of

9. Experiencia vivida e liberdade : (estudo da liberdade em Jean-Paul Sartre)
In the following pages I shall attempt to situate Jean-Paul Sartre s reflexion on freedom, defined in a first moment by the spontaneity of translucid consciousness, advancing in way of giving back a dimension of opacity for freedom, that acquires an ambiguous sense of choice and consent, rupture and agreement and, thus, involving in its own constitution a pa

10. Modelos de vidros de spin com interações de ordem alta. / Spin glasses models with high-order interactions.
The statistical properties of the local optima (metastable states) of the infinite range Ising spin glass with p-spin interactions in the presence of an external magnetic field h are investigated analytically. The average number of optima as well as the typical overlap between pairs of identical optima are calculated for general p. For p > 2 and small h w

11. Mutations Linked to Leukoencephalopathy with Vanishing White Matter Impair the Function of the Eukaryotic Initiation Factor 2B Complex in Diverse Ways
Leukoencephalopathy with vanishing white matter (VWM) is a severe inherited human neurodegenerative disorder that is caused by mutations in the genes for the subunits of eukaryotic initiation factor 2B (eIF2B), a heteropentameric guanine nucleotide exchange factor that regulates both global and mRNA-specific translation. Marked variability is evident in the

12. Kostant polynomials and the cohomology ring for G/B
The Schubert calculus for G/B can be completely determined by a certain matrix related to the Kostant polynomials introduced in section 5 of Bernstein, Gelfand, and Gelfand [Bernstein, I., Gelfand, I. & Gelfand, S. (1973) Russ. Math. Surv. 28, 1–26]. The polynomials are defined by vanishing properties on the orbit of a regular point under the action o
