1. Do amor como falta: uma abordagem pedagógica
Resumo No presente artigo assumimos o objetivo de elucidar a relevância de se tomar o amor como falta enquanto objeto de estudo da educação escolar, abordando-o, especialmente a partir da educação moral. Para tanto, partimos de uma revisão bibliográfica sobre o tema, evidenciando a tensão entre razão e emoção que permeou a compreensão sobre o amo

2. Migraciones calificadas: el caso de las colombianas en Buenos Aires
Abstract This article stems from the observation of a small group of highly qualified young women, who reside in the Autonomous City of Buenos Aires. A qualitative analysis of the migratory paths of these women is performed from a psychological and social dimension. An examination of the motivations for migration shows a strong need of emotional and economic

3. Numerical Modelling of Crack Propagation in Cement PMMA: Comparison of Different Criteria
Modelling of a crack propagating through a finite element mesh under mixed mode conditions is of prime importance in fracture mechanics. In this paper, three different crack growth criteria and the respective crack paths prediction in the cement mantle of the reconstructed acetabulum are compared. The maximum tangential stress (MTS) criterion, the minimum st

4. Impact Response of Aluminium Alloy Foams Under Complex Stress States
Abstract A series of dynamic tests were conducted on a closed-cell aluminum alloy foams in order to determine experimental failure surface under impact loading conditions. Quasi-static tests have also been performed to investigate failure mechanism under different stress paths. Three typical types of deformation modes can be observed, which corresponds to th

5. Where is my car? Examining wayfinding behavior in a parking lot
This article examines wayfinding behavior in an extended parking lot belonging to one of the largest shopping malls in Santiago, Chile. About 500 people were followed while going to the mall and returning from it, and their trajectories were mapped and analyzed. The results indicate that inbound paths were, in average, 10% shorter that outbound paths, and th

6. Analysis of mechanical behavior of an expansive soil from the oil province of Urucu-AM for paving / Análise do comportamento mecânico de um solo expansivo da província petrolífera de Urucu-AM para fins de pavimentação
The establishment of transportation infrastructure is critical to the development of the Urucu- AM region, a newly developed oil exploration area in the Amazonas state. The construction of such infrastructure is challenging due to the lack of suitable materials for the construction pavement base and subbase courses and adverse weather conditions, with altern

7. Estudo do encruamento dos aços AISI 304 e AISI 409 com uso da técnica de cisalhamento planar simples
This research analyzed the effect of successive changes in the strain path of AISI 304 (type 304N) and AISI 409 stainless steel sheets on their work hardening behavior. Plastic deformation was imposed on these materials employing successive simple planar shear, tension or plane strain. These steels were chosen because of their contrasting work hardening beha

8. DESENVOLVIMENTO DE UM SISTEMA TRIAXIAL SERVO-CONTROLADO E AVALIAÇÃO DO COMPORTAMENTO MECÂNICO DE UM SOLO RESIDUAL DE BIOTITA GNAISSE / DEVELOPMENT OF A SERVO-CONTROLLED TRIAXIAL EQUIPAMENT AND EVALUATION OF MECHANICAL BEHAVIOUR OF A BIOTITE-GNEISS RESIDUAL SOIL
This dissertation presents a study of the mechanical properties of biotite gneiss residual soil found at Alto Leblon, Rio de Janeiro, and the development of a triaxial equipment for unsaturated soil testing. An experimental program has been created to study the mechanical behaviour of soil. The methodology proposed by this campaign is: (a) physical character

9. Narração e doutrina na Constante Florinda: exempla estóicos para a vida cristã / Narration and doctrine in Constante Florinda: exempla stoics for christian life
Gaspar Pires de Rebelos Infortúnios trágicos da constante Florinda was published in 1625. Given its conspicuous success, a sequel, Segunda parte da Constante Florinda, em que se trata dos infortúnios que teve Arnaldo buscando-a pelo mundo, came out in 1633. Constante Florinda (this is the title both parts became known as), largely disseminated in the 17th

10. Cartografias de um lugar imaginário : uma travessia pelo romance Calunga, de Jorge de Lima.
The course of this crossing aims to (re)discover aesthetic and stylistic configurations in Jorge de Limas novel Calunga, by observing Levitass (1990) discussions on the three aspects of utopia (form, function and content) as its theoretical cartography. Regarding the issue of form, the analysis proposes that novel signals two ruptures: the dissolution of bar

11. Equipment cubic triaxial for rehearsals in saturated soils and no saturated with suction controlled matric / Equipamento triaxial cúbico para ensaios em solos saturados e não-saturados com sucção matricial controlada
In tropical countries, like Brazil, soils in non saturated condition are frequently encountered. Besides, the majority of geotechnical works load the ground according to stress paths in which the three principal stresses are different and vary independently. Therefore, the need to develop equipments able to test in the laboratory non saturated soil samples f

12. Characteristics of the double-torsion test to determine the R-curve of ceramic materials
Double-torsion tests were carried out on a commercial ceramic floor tile to verify whether this test is suitable for determining the R-curve of ceramics. The instantaneous crack length was obtained by means of compliance calibration, and it was found that the experimental compliance underestimates the real crack length. The load vs. displacement curves were
