La presente investigación analiza el diagnóstico del Plan de Manejo de Residuos Sólidos del distrito de La Victoria, periodo 2016 - 2020, para ello, el estudio parte de un marco conceptual y metodológico para identificar los vacíos y aspectos de mejora del diagnóstico que sirvan para el próximo Plan de Manejo de Residuos Sólidos del distrito. Así, se toma como base las pautas de contenido del diagnóstico de la Guía para Elaborar el Plan Distrital de Manejo de Residuos Sólidos del Ministerio del Ambiente las que se complementan con guías internacionales de manejo de residuos sólidos a partir de la base teórica de la Gestión Integral de los Residuos Sólidos y la Planificación Estratégica. En esa línea, se analizaron las subvariables que resultaron de la indagación de las guías mencionadas anteriormente, encontrando aspectos no desarrollados y otros incompletos en el diagnóstico del Plan de Manejo de Residuos Sólidos del distrito de La Victoria, periodo 2016 - 2020. En la investigación se ha empleado un enfoque cualitativo, con alcance descriptivo y empleando la estrategia de estudio de caso único incrustado. Asimismo, para recopilar información, se realizó una revisión documental y entrevistas semiestructuradas a funcionarios de la Municipalidad de La Victoria y especialistas en gestión de residuos sólidos. La información recopilada fue analizada a través de una rúbrica de evaluación cualitativa que asigna atributos de evaluación por cada sub variable: logrado, en progreso e incipiente. Esta investigación concluye que el diagnóstico del Plan de Manejo de Residuos Sólidos del distrito de La Victoria, periodo 2016 - 2020, se encuentra “en progreso” al encontrarse vacíos y aspectos de mejora que deberán abordarse en el próximo diagnóstico del Plan. Su mejora representa no solo una oportunidad para evitar los impactos negativos en la salud y medio ambiente, sino también para valorizar recursos, lograr beneficios económicos, sociales y avanzar hacia un futuro sostenible.

This thesis consists of six published papers. The present-day stress tensor has been determined using petroleum well data in the Gippsland and Otway Basins in Southeast Australia (Papers 1 and 4) and the Cooper Basin in Central Australia (Paper 5). In the Gippsland Basin, the present-day stress regime is transitional between one of reverse and strike-slip faulting and the maximum horizontal stress (SHmax) is oriented ~139°N. The present-day stress regime in the Victorian sector of the Otway Basin is also transitional between one of reverse and strike-slip faulting and SHmax is oriented ~135°N. Horizontal stresses are lower in the South Australian sector of the Otway Basin where the stress regime is one of strike-slip faulting and SHmax is oriented ~124°N. The orientations of SHmax in Southeast Australia are consistent with focal mechanism solutions, neotectonic structures and modelling of plate-boundary forces (Paper 4). Closure pressures from mini-frac injection tests are commonly used to determine the minimum horizontal stress (Shmin) magnitude. However, in high stress basins such as the Cooper and Gippsland Basins, these pressures may not reliably yield Shmin (Papers 2 and 5). In the Cooper Basin, high closure pressures (>18 MPa/km) were observed in tests where pressure-declines indicated complex hydraulic fracture growth. Closure pressures in these injections are unlikely to be representative of Shmin. They are believed to reflect the normal stress incident on pre-existing planes of weakness that are exploited by hydraulic fluid during the mini-frac injection (Paper 5). Sub-horizontal fabrics that are open at the wellbore wall were observed on image logs in the Cooper and Gippsland Basins (Papers 2 and 5). This fabric is believed to be at least partially responsible for the complex growth of hydraulic fractures observed in the Cooper Basin. The occurrence of these sub-horizontal fabrics and knowledge of rock strength have been used to constrain the magnitudes of SHmax and Shmin independently of mini-frac injections in the Cooper and Gippsland Basins (Papers 2 and 5). The present-day stress tensor is often quoted as a single gradient at a sedimentary basinor petroleum field-scale. Image logs and mini-frac data from Central and Southeast Australia indicate significant stress differences between stratigraphic units (Papers 3 and 5). Finite element modelling of the stress distribution between interbedded sands and shales in the Gippsland Basin indicates that stress is ‘partitioned’ to ‘hard’ lithological units in high stress areas. This accounts for the observation that borehole breakout only occurs in hard, cemented sandstones in the Gippsland Basin (Paper 3). A generic ‘mechanical stratigraphy’ derived from knowledge of wellbore failure (from image logs), rock strength and rock properties in individual rock units in the Cooper Basin allows an approximation of the present-day stress-state to be made directly from image-logs for individual rock units prior to mini-frac injection (Paper 6). This is important for predicting and understanding hydraulic fracture growth and containment. When considered together, the papers comprising this thesis provide significant new data on the orientation and magnitude of present-day stresses in Central and Southeast Australia. They also provide insight into the tectonic origin of those stresses and their distribution within sedimentary basins. In particular the papers develop and use new methods for constraining the present-day stress in regions of high tectonic stress. They also discuss implications for problems in petroleum development including wellbore stability and hydraulic fracturing. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1283781 / Thesis(Ph.D.) -- Australian School of Petroleum, 2007

"The study examines two decades in the musical life of Ballarat, a regional city in south-eastern Australia. Beginning at the time of the 1851 gold rush, it covers the period in which Ballarat grew from a rough mining camp to an established city with a socially and ethnically diverse population of over 40,000 people. The thesis pursues the aim of looking at the music practices of the community in ways that will further our understanding of the significance of music in the lives of the people."--Abstract. / Doctor of Philosphy
