This thesis is an investigation into some of the influences, reasons, concepts and processes in my sculptural practice. Referencing the use of absurdity, pseudoscience, mythological instrumentality, and normal consumer logic, it is a questioning into what type of cultural production is viable within a contemporary art context.

Annotation: The main topic of this thesis is an analysis of tameness and wildness phenomena in particular Hermann Hesse's novels. Thesis will aim to expressions and interpenetrations of those phenomena and their position in period mind frame.Aim will be chronological analysis of those phenomena, their evolution and change in particular novels and an attempt of their synthesis. Key words: Hesse, Nietzsche, tammeness, wildness, Freud, Jung, Demian, Steppenwolf, Narcissus and Goldmund, The Glass Bead game, dialectic, dualism

The study encompasses the reconstruction of the Iron Age sequence around the Limpopo River floodplain on Basinghall Farm during the second millennium AD. A survey uncovered 75 Iron Age sites, including three Moritsane and ten Toutswe facies sites for the Middle Iron Age and two Early Moloko, 16 Middle Moloko (Letsibogo facies) and 43 Late Moloko grain bin platform sites for the Late Iron Age. The local settlement sequence, which is based primarily on a ceramic analysis of surficial and excavated collections, is corroborated by radiocarbon dates, a glass bead sequence and comparative data from previous studies. The borders of the Toutswe chiefdom are shown to have extended 100 km to the south, while the Eiland sequence is refined to include an Eiland, a Moritsane and a redefined Broadhurst facies. New light is also shed on the local Moloko sequence and its correlation with historical Tswana groups in south-eastern Botswana. / Anthropology & Archaeology / M.A. (Archaeology)

Cette étude a pour objectifs la caractérisation expérimentale des frottements saccadés dans les matériaux granulaires modèles constitués des billes de verre monodisperses en compression triaxiale drainée et l'identification des paramètres de contrôle. Cinq paramètres macroscopiques caractérisent ces frottements saccadés : la chute de déviateur et la contraction volumique, l'intermittence de déformation axiale, le module d'Young et le coefficient de Poisson. Les frottements saccadés affectent simultanément le déviateur et la déformation volumique. Le comportement macroscopique est globalement contractant tandis que le matériau tend vers un état limite critique en grandes déformations, à la manière des sables lâches. Cependant il présente localement, dans les phases de blocage qui suivent immédiatement les ruptures temporaires, le comportement dilatant des sables denses, qui obéit à une relation contrainte-dilatance linéaire et unique. Les frottements saccadés disparaissent au-delà d'une vitesse critique d'écrasement axial, qui dépend de la contrainte de confinement et de la taille des grains. Le module d'Young dynamique par propagation d'ondes varie avec la contrainte de confinement selon une loi de puissance. Le module d'Young quasi-élastique au départ des phases de blocage est constant à l'intérieur du domaine élastique, de même que le coefficient de Poisson. Le suivi par granulométrie laser et par analyse d'images des matériaux après un ou plusieurs essais triaxiaux permet de suivre l'évolution de la taille moyenne et de la forme des grains. Tandis que les instabilités par saccade disparaissent suite à un certain nombre d'essais, on observe, simultanément à une légère diminution du volume moyen, l'apparition progressive de populations d'objets non sphériques par une fusion des grains analogue au frittage. / The objectives of this study are the experimental characterisatino of the stick-slip instabilities in a model granular material and the identification of relevant control parameters. As monodisperse glass beads are subjected to drained triaxial compression tests, five macroscopic parameters characterize the stick-slip phenomenon: the deviator drop, the jump in volumetric contraction, the intermittence of the axial strain, Young’s modulus and Poisson’s ratio. The stick-slip events simultaneously affect the deviator stress and the volumetric strain. While the global material behavior is that of a loose sand, gradually contracting and hardening as it approaches its large strain critical state, its response in the “stick” phases immediately following the “slip” instabilities is similar to that of dense, dilatant sands, with a unique, linear stress-dilatancy relationship. Stick-slip events disappear beyond a critical axial strain rate, depending on the confining stress and on the grain diameter. The Young modulus associated to wave propagation varies with the confining stress according to a power law. The quasi-elastic modulus measured at the beginning of the stick phase is constant inside the elastic domain, as well as the Poisson ratio. The evolution of grain size and shape after one or several triaxial tests is monitored by laser granulometry and image analysis. The gradual vanishing of stick-slip events, on repeating the tests, is likely related to the global decreasing trend of average particle volume and to the formation of non-spherical objects, apparently by some phenomenon analogous to sintering.
