Numerical modelling of rows of discrete piles used to stabilise landslides under long-term conditions in clays
No full textA literature review found no rigorous solution for the ultimate lateral pile-soil pressure ( ) in a soil characterised by a frictional failure criterion, and that the popular empirical methods to estimate give profiles with depth that differ significantly. Most existing solutions for the lateral pile capacity in a group are for soil characterised by an undrained shear strength failure condition. Plane strain and constant overburden finite difference analyses (in FLAC3D) were used to model flow of soil around a pile but did not appear to give sensible solutions for a frictional soil. The ultimate pile-soil line load from three-dimensional analysis in FLAC3D behaved as physically expected; passive wedges formed close to the surface giving lower normalised resistance than at greater depths. A number of parametric analyses were carried out using the three-dimensional model to investigate the variation in the ultimate pile-soil line load with the soil strength and pile-soil interface strength. Larger values of initial earth pressure coefficient K0 led to enhanced values of and the mechanisms for this was further investigated by analysing the soil stresses mobilised around the pile as the soil was pushed with the pile. Limit equilibrium pile failure mechanisms were developed from conditions of force and moment equilibrium for the pile based on failure in the soil. Pile limit equilibrium conditions were determined for three failure modes to understand the relationships between pile shear force, bending moment and pile embedment length ratio. Three-dimensional numerical (FLAC3D) models were used to verify the limit equilibrium failure mechanisms. The limit equilibrium equations were found to provide unconservative predictions for the force that the pile can provide to stabilise a slope, compared with the FLAC3D analysis. The program Alp (which models the pile as a beam on springs) gave results that were close to the limit equilibrium calculations. Three-dimensional FLAC3D models were modified to investigate the conditions over which the derived limit equilibrium pile failure mechanisms could reasonably be applied. The centre-to-centre pile spacing was varied from 1 d to 10 d, where d is the diameter of the pile, to understand the pile-soil interaction for a row of piles using the FLAC3D model. When the pile spacing was less than 2 d, the pile stabilising force was the same as for a solid retaining wall. Beyond about 4 d, the piles were found to act individually

Old Friendships: Exploring the Historic Relationship Between Pan-Islamism and Japanese Pan-Asianism
No full textThis thesis examines the relationship between Japanese pan-Asianists and pan-Islamists from the end of the nineteenth century till World War II. The materialization of pan-Asianism in Japan and pan-Islamism in the Ottoman Empire was a response to the perceived acts of aggression against a fictive and universal "West." Both pan-Asianism and pan-Islamism emerged as a reaction to the strong currents of anti-Western discourse. The trajectories of both pan-Asianism and pan-Islamism intertwined with major turning points in international history, such as the Russo-Japanese War (1904-1905), WWI, and later in the 1930s after the Japanese occupation of Manchuria. Intellectuals involved in both these movements engaged in intense debates about race, civilization, and empire. It was such transnational imaginations that laid the foundations of Japanese-Ottoman interactions. Pan-Islamists, keen on uniting the social, religious, and political recesses evident in the Islamic world, sided with Japanese pan-Asianists in the Early Meiji Era. It was the desire of pan-Islamic intellectuals to join forces with Japan for the purpose of constructing a twentieth century utopia under the banner of Islam, which was suitably modern, spiritual, and able to withstand Western hegemony. According to them, the strength of Japanese pan-Asianism combined with the universality of pan-Islamism's message was an integral force in the "awakening" of Muslims around the globe. Also, Japanese pan-Asianists were keen to engage in diplomatic discourse with Ottoman intellectuals so as to overturn the Orientalist framework that had condemned the Eastern nations to a status of inferiority by the Occident. This thesis, therefore, connects Japanese history to the world of Islam and investigates how the accepted notions of Orient and Occident, East and West, Self and Other, engineered a relationship between two very different nations. The embracing of Japan by pan-Islamist intellectuals and the affinity of pan-Asianism's message as the East's answer to the West (as an equal in matters of race, civilization, and culture) is indicative of an association incumbent upon restructuring the global power politics of the time
Badanie właściwości termoluminescencyjnych polikrystalicznej struktury diamentowej wytworzonej metodą CVD w IFJ PAN
No full textW IFJ PAN wytworzono strukturę diamentu polikrystalicznego na 2” podkładzie krzemowym o grubości 2 mm w reaktorze CVD produkcji Seki Technotron. Średnia grubość utworzonej warstwy wynosi 118.9 μm. W celu zbadania właściwości termoluminescencyjnych naświetlono strukturę dawkami z zakresu 0.25 - 60 Gy, stosując aparat Theratron 780E ze źródłem Co-60. Sygnał TL mierzono planarnym czytnikiem detektorów termoluminescencyjnych. Próbka charakteryzuje się rozrzutem czułości na poziomie 280%. W widmie termoluminescencyjnym zaobserwowano 2 wyraźne piki w temperaturze 96ºC, 220ºC. W przedziałach dawek 0.25 – 2 Gy oraz 20 – 60 Gy stwierdzono liniową zależność od dawki, po anilacji próbki w temperaturze 400ºC czułość zmniejszyła się
