O contrato social de Thomas Hobbes: alcances e limites
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas. Programa de Pós-Graduação em FilosofiaO problema em questão diz respeito ao contrato que funda e legitima o Estado em Thomas Hobbes. Tendo como escopo questionar a possibilidade e/ou impossibilidade de nulidade do contrato social e assim verificar as implicações disto para o conceito de soberania hobbesiana. A leitura que impera na tradição de estudiosos da obra política de Hobbes, em especial do Leviathan, é a de um Estado no qual a soberania é absoluta e irrevogável. A interpretação do contrato firmado entre e, somente, entre os homens, deixando, portanto, o soberano de fora, ofereceria legitimidade a este para agir de forma absoluta e obrigaria ao súdito a obedecer de forma irrestrita. A hipótese que se busca sustentar remete à possibilidade de rompimento, desobediência e mais centralmente da nulidade contratual a partir do vício e/ou desrespeito de determinadas cláusulas fundamentais do contrato, visto se oporem às condições de validade do contrato social. Se isso puder ser sustentado desse modo, isto é, se Hobbes compartilhar mesmo de uma teoria forte da nulidade contratual e pela razão, como declinado acima, que achamos ser a correta, então, tal formulação implicaria em sua teoria uma reconsideração do conceito de soberania e obediência, haja vista o estabelecimento de certos vínculos fortes que condicionam as possibilidades de exigência, autoridade e poder da soberania. Portanto, concentra-se em encontrar uma explicação e/ou teorização da nulidade do contrato social e da sua consequência para a teoria da soberania e obediência hobbesiana

Spatiotemporal evolution of the trail network in Lasius fuliginosus (Hymenoptera, Formicidae)
No full textIn Lasius fuliginosus, the existence of a permanent trail system, stable during a season and practically unchanged from one year to the next, was confirmed. These trails radiate from the nest and lead the foragers to trees and shrubs colonized by aphids where they collect honeydew. Other kinds of trails were observed: temporary honeydew collecting trails, temporary hunting trails and ephemeral recruitment trails. -from AuthorsSCOPUS: NotDefined.jinfo:eu-repo/semantics/publishe

La notice sur sanctum, religiosum, sacrum et profanum dans le commentum du Pseudo-Agennius
No full textThe notice of Pseudo-Agennius’ commentum about sanctum, religiosum, sacrum and profanum.
Examining the text in which Pseudo-Agennius Urbicus’ commentum on Frontinus deals with loca sacra et religiosa (Thulin, Corpus agrimensorum Romanorum, p. 68 l. 9-28) shows not only that the author used Macrobius’ Saturnalia, but also how he christianized this passage.L’examen du texte que le commentum du Pseudo-Agennius Urbicus sur Frontin consacre aux loca sacra et religiosa (p. 68 l. 9-28 du Corpus agrimensorum Romanorum de Thulin) fait apparaître l’utilisation des Saturnales de Macrobe par le commentateur, mais également certains éléments de christianisation du passage.Guillaumin Jean-Yves.

Geophysical characterization of subsurface biofuel contamination and biodegradation
No full textIn the last two decades, the production of ethanol (EtOH), one of the most common biofuels in the USA, has substantially increased due to regulations aiming at reducing air pollution and providing a supplement to petroleum. Scenarios of large spills of EtOH during production, transportation and at storage facilities are likely. Accidental release of EtOH and its persistence in the subsurface pose threats to human health and the environment, including the deterioration of municipal water supplies. Thus, there is a need to develop adequate monitoring tools to help with the remediation efforts of subsurface EtOH contamination. Ethanol presence, interaction and biodegradation could substantially alter the electrical properties of geologic materials, thereby potentially leading to distinctive geophysical responses. This dissertation demonstrates the potential application of non-invasive and cost effective complex resistivity (CR) technique for the characterization of biofuel contamination and biodegradation in the subsurface. The first research topic examined the electrical geophysical signatures arising from groundwater contamination by EtOH. Conductivity measurements were performed at the laboratory scale on EtOH-water mixtures (0 to 0.97 v/v EtOH) and EtOH-salt solution mixtures (0 to 0.99 v/v EtOH) with and without a sand matrix. A mixing model was used to simulate electrical conductivity as a function of EtOH concentration in the mixture. It was found that increasing EtOH concentration resulted in a decrease in measured conductivity magnitude ( ), which reflected changes in relative strength of the types of interactions occurring in EtOH-water mixtures. The second research topic explored the electrical properties associated with EtOH-clay interactions using CR measurements on laboratory columns of varying ethanol (EtOH) concentration (0% to 30% v/v) in a sand-clay (bentonite) matrix. A Debye Decomposition approach was applied to fit the CR data. Overall, the results showed a significant suppression (P ≤ 0.001) of the clay driven polarization with increasing EtOH concentration. The suppression effects are associated with alterations in the electrical double layer (EDL) at the clay-fluid interface due to strong EtOH adsorption on clay and complex intermolecular EtOH-water interactions. The persistent EtOH adsorption on clay also indicated strong hysteresis effects in the electrical response. The third research topic investigated changes in electrical properties during EtOH biodegradation processes in sand matrix using CR measurements in conjunction with geochemical data analysis on microbial stimulated (inoculation of bacterial cells) and control (without bacteria inoculation) columns. A Debye Decomposition approach was applied to fit the CR data. Overall, the results showed a clear distinction between the bio-stimulated and control columns in terms of real ( ) and imaginary ( ) conductivity, phase ( ) and apparent formation factor (Fapp). Temporal geochemical changes and high resolution scanning electron microscopy imaging corroborated the CR findings, thus indicating the sensitivity of CR measurements to EtOH biodegradation processes.Ph.D.Includes bibliographical referencesIncludes vitaby Yves Robert Personn
