Item El por qué de la vida : conferencia leida el 18 de julio de 1915 en la primera sesión pública del "Centro Científico-literario"(Imprenta Boliviana, 1915) Iturricha, Agustín, 1863-Item A fracture mechanics approach to accelerated life testing for cathodic delamination at polymer/metal interfaces(2013-05) Mauchien, Thomas Kevin; Liechti, K. M.This work presents a fracture mechanics analysis of the cathodic delamination problem for the polyurethane/titanium and polyurea/steel interfaces. The nonlinear behavior of both polymers was investigated. The recent Marlow model was used to define the strain energy function of the polymers. Viscoelastic effects of the polyurea were also studied. The Marlow model was associated with a nine-term Prony series. This model was seen to represent experimental data relatively well for a wide range of strain rates both in tension and compression. The driving force for delamination, the strain energy release rate G, is presented for both interfaces. Cathodic delamination data for several temperatures are presented as crack growth rate as a function of crack driving force. The approach recognizes that both temperature and stress can be used as accelerated life testing parameters.Item The sea as a two-way passage between life and death in Greek mythology(2008-05) Beaulieu, Marie-Claire Anne, 1979-; Perlman, Paula JeanThe sea has two major roles in Greek mythology. It is associated with the voyage into Hades, and as the primordial water, Oceanus, it represents vitality and even eternal life. Until now, scholars have viewed these two aspects as fundamentally antinomic. I propose to treat them as complementary to show that the sea is an intermediary locus between the earth and the Underworld that allows initiatory passages to adulthood, heroization, and divinization by symbolic death and return to life. For women, immersion, just like a nuptial bath, is a one-way, irrevocable transformation from parthenos to gynê that separates them forever from their families. In myths such as those of Danae and Auge, girls find a husband and a new community in foreign lands as well as a new identity as queens after having been exposed on the sea by their families. The chest in which they are shut with their illegitimate children conveys the double meaning of the myth: it saves the heroines' lives, but it was also used as a bier in Antiquity. Conversely, girls such as Britomartis leap into the sea to get away from their lovers. Their immersion is an escape from the power of Eros, an anti-initiation into adulthood. This denial of Eros is also present in Sappho's leap at Leucas. The poet escapes Eros and enters Hades by leaping down the cliff and she returns to the earth free from passion. For adolescent men, immersion into the sea is a two-way passage accomplished under no compulsion. Taras' and Theseus' passage in the sea results in their recognition as the sons of gods. They return to their communities as fully integrated leaders.
