Full textAbstract:
European expansion caused dramatic dislocation for Aboriginal populations in the landmass that became the state of Queensland. On the frontiers, violence, abductions and forced relocations occurred on a largely informal basis condoned by colonial governments. The introduction of protective legislation in the late nineteenth century created a formal state-directed legal and administrative framework for the forcible removal and institutionalisation of Aboriginal people. This became the cornerstone for policy direction in Queensland and remained so into the mid-twentieth century. This thesis traces the development of policies and practices of removal in Queensland from their beginnings in the nineteenth century through to their dismantling in the mid-twentieth century. There has been much historical research into frontier violence and processes of dispossession in Queensland. The focus of this study is the systematic analysis of archival data relating to the forced removals of the twentieth century. The study has its genesis in an Australian Research Council Strategic Partnership with Industry — Research and Training Scheme (SPIRT) grant. This grant enabled the construction of a Removals Database, which provides a powerful tool with which to interrogate available records pertaining to removals of Aboriginal people in Queensland. Removals were a crucial element in the gathering and exploitation of Aboriginal labourers during the twentieth century. They also constituted a major form of control for the departments responsible for Aboriginal affairs within the Queensland administration. Tensions between a policy of complete segregation and the demand for Aboriginal labour in the wider community existed throughout the period of study. While segregation was implemented to an extent in relation to targeted sections of the Aboriginal population, such as “half-caste” females, employer insistence on access to reliable, cheap Aboriginal labour invariably took precedence. Detailed analysis of recorded reasons for removals demonstrates that they are unreliable in explaining why individuals were actually removed. They show a changing focus over time. Fluctuations in numbers of removals for different years reflect reasons not officially acknowledged in the records, such as the need to populate newly created reserves and establish institutional communities. They tell us little about the situation of Aboriginal people, but much about the racial thinking of the time. This study contributes to our knowledge base about the implementation and extent of Aboriginal child separation in Queensland. A comprehensive estimate of the number of separations concludes that one in six Aboriginal children in Queensland were separated from their natural families as a result of past policies. Local Aboriginal Protectors (usually police officers) played a major role in the way that the policy of removals was implemented. Local factors often determined the extent of removals as much as policy direction in the centralised Office of the Chief Protector of Aborigines. Removals took place across vast distances, and the Chief Protector was often totally reliant on local protectors for information and advice. This meant that employers and local protectors could have a major impact on the rate of removals in a given location. Responses of both Protectors and Aboriginal people to the policy of removals were not always compliant. Some Protectors worked to ensure that local Aboriginal people could remain in their own community and geographical location. Aboriginal people demonstrated a degree of resistance to the policy and there are a numerous recorded examples of extraordinary human endurance where they travelled large distances in difficult circumstances to return to their original locations and communities. The policy of removals impacted on virtually every Aboriginal family in the state of Queensland and the effects of the dislocations continue to be experienced to this day.Thesis (PhD Doctorate)

Full textAbstract:
In Australia, over-representation of Aboriginal and Torres Strait Islander children in child protection systems is increasing. The legacy of the stolen generation has led to grief, sadness and loss of identity for many people, and major disparities in health, education, employment and housing means that Aboriginal and Torres Strait Islander families are more susceptible to child welfare interventions in the present and future. This makes it imperative that responses for these families are more effective, in order to achieve socially just outcomes. As well, Australia’s growing multicultural society has increased demand for services provided to people from diverse cultural backgrounds to recognise the impact and importance of culture and to respond effectively. Cultural competency, which focuses on developing knowledge, skills and values for cross cultural practice, has gained momentum. It aims to enhance the ability of workers to provide culturally relevant and effective responses to people from different cultural backgrounds. However, ensuring that practices in the human services are culturally appropriate, culturally safe, salient, and effective, has proved elusive.Thesis (PhD Doctorate)

As a member of the Stolen Generations, my objective and design in this dissertation is part of a larger project, involving the reclamation of my Aboriginal identity, taken from me as a child. I will attempt to do this through researching the lives of my grandfather George Shaw and his daughters, Ruby Janie and Maggie. Through a reading of files and documents held by the Department of Indigenous Affairs, Perth, I will show how the 1905 Aborigines Protection Act impacted on the lives of the Shaw family, and on all Aboriginal people who lived under this oppressive regime.
Through the disclosure of what life was like for me as a child removed, I attempt to identify the shameful lack of care by the authorities concerned with my removal. The rational behind this piece of work is based on a desire to further my own personal journey of healing by linking my story to the larger Shaw story.

Murphy, Sytil Kathleen. "Anti-Stokes generation in a continuous wave raman laser." Thesis, Montana State University, 2008. http://etd.lib.montana.edu/etd/2008/murphy/MurphyS0808.pdf.
Full textAbstract:
The continuous-wave Raman laser system differs from other Raman systems in that it uses cavity enhancement to augment the pump laser source rather than a high-power pulsed laser source. Through interactions of the pump laser with the Raman active medium, all Raman systems can produce both red-shifted, Stokes, emission and blue-shifted, anti-Stokes, emission. Previous, continuous-wave Raman laser systems have focused on the Stokes emission. This dissertation presents theory and data on the anti-Stokes emission. Specifically, it investigates the anti-Stokes mode structure and the emitted power as a function of input pump power, detuning, pressure, and mode combination. In order to be able to compare theory to data, the existing semi-classical CW Raman laser theory is extended to include the possibility that the spatial mode of any of the three fields (pump, Stokes, or anti-Stokes) is not the fundamental spatial mode. Numerical simulations of this theory are used to understand the behavior of the CW Raman system. All the data is compared to the theory, with varying degrees of success. The pump laser used in this research is a frequency-doubled Nd:YAG at 532 nm and the Raman active medium is H 2. This combination results in Stokes and anti- Stokes wavelengths of 683 nm and 435 nm, respectively. Five methods were found in this research for increasing the amount of anti-Stokes emitted: increasing the input pump power, detuning from gain line-center of the Stokes emission, increasing the reflectivity of the cavity mirrors at the anti-Stokes wavelength, switching to a higher-order spatial mode, and decreasing the H 2 pressure within the Raman cavity. In general, it was found that the higher-order anti-Stokes modes did not agree with a single theoretical spatial mode. Superpositions were formed of multiple theoretical spatial modes giving intensity distribution across the profile similar to the measured profile. Three theoretical spatial mode symmetries were investigated: rectangular, cylindrical, and elliptical. Also measured was the Raman gain as a function of pressure. The accepted theory for the Raman linewidth was found to be slightly off.

Full textAbstract:
Numerical solutions of the Navier-Stokes Equations became more popular in recent decades with increasingly accessible and powerful computational resources. Simulations in reconstructed or artificial pore geometries are often performed to gain insight into microscopic fluid flow structures or are used for upscaling quantities of interest, like hydraulic conductivity. A physically adequate representation of pore-scale flow fields requires analysis of large domains.
We solve the incompressible NSE in artificial ordered and random pore-space structures. A simple cubic and face-centred packings of spheres placed in a square duct are analysed. For the fluid flow simulations of random media, packings of spheres, icosahedra, and cubes forming unconsolidated sediments are generated using a rigid body simulation software. The Direct Numerical Simulation method is used for the solution of the NSE implemented in the open-source computational fluid dynamics software OpenFOAM.
The influence of the number of spheres in ordered packings, the mesh type, and the mesh resolution is investigated for fluid flow up to Reynolds numbers of 100 based on the spheres' diameter. The random media mesh generation method relies on approximate surface reconstruction. The resulting tetrahedral meshes are then used for steady-state simulations and refined based on an a-posteriori error estimator.
The fluid flow simulation results can further be used twofold:
1) They provide homogenized hydro-mechanical properties of the analysed medium for the larger meso and macro groundwater flow simulations. A concept of one-way binding for large-scale simulations is presented.
2) Visualisation: A post-processing image rendering technique was employed in interactive and still image visualisation environments allowing better overview over local fluid flow structures.
The ogs FEM code for the solution of large-scale groundwater processes was inspected for computational efficiency. The conclusions drawn from this analysis formed the~basis for the implementation of the~new version of the code---ogs6. The improvements include comparison of linear algebra software realisations and an implementation of optimized memory access patterns in FEM-local assembler part.

Full textAbstract:
A fully automated Cartesian/Quad grid generator and laminar flow solver have been developed for external flows by using C++. After defining the input geometry by nodal points, adaptively refined Cartesian grids are generated automatically. Quadtree data structure is used in order to connect the Cartesian cells to each other. In order to simulate viscous flows, body-fitted quad cells can be generated optionally. Connectivity is provided by cut and split cells such that the intersection points of Cartesian cells are used as the corners of quads at the outmost row. Geometry based adaptation methods for cut, split cells and highly curved
regions are applied to the uniform mesh generated around the geometry. After obtaining a sufficient resolution in the domain, the solution is achieved with cellcentered approach by using multistage time stepping scheme. Solution based grid adaptations are carried out during the execution of the program in order to refine the regions with high gradients and obtain sufficient resolution in these regions. Moreover, multigrid technique is implemented to accelerate the convergence time significantly. Some tests are performed in order to verify and validate the accuracy and efficiency of the code for inviscid and laminar flows.

Full textAbstract:
A finite-volume procedure, comprising a gradient-reconstruction technique and a multidimensional limiter, has been proposed for upwind algorithms on unstructured grids. The high-resolution strategy, with its inherent dependence on a wide computational stencil, does not suffer from a catastrophic loss of accuracy on a grid with poor connectivity as reported recently is the case with many unstructured-grid limiting procedures. The continuously-differentiable limiter is shown to be effective for strong discontinuities, even on a grid which is composed of highly-distorted triangles, without adversely affecting convergence to steady state. Numerical experiments involving transient computations of two-dimensional scalar convection to steady-state solutions of Euler and Navier-Stokes equations demonstrate the capabilities of the new procedure.

Full textAbstract:
This thesis focuses on processes of Aboriginal community-making in Redfern, an inner city suburb of Sydney, Australia. It addresses the ways in which the Australian state governs Aboriginal people by developing 'projects of legibility' (and illegibility) concerning Aboriginal community sociality. To address Redfern Aboriginal community-making requires focusing on the ambiguities arising from the contemporary policy of 'Aboriginal self-determination' and adopting an ethnohistorical approach to Aboriginal community-making that has arisen under this policy rubric. By ethnohistorical I refer to the engagement of Aboriginal people in Redfern in Aboriginal community-making policy practices and not a historiography of these policies. Attention will be paid to past and present negotiations concerning the (re)development of the Redfern Aboriginal community and their intersections in the state-led redevelopment process Aboriginal community- makers were engaged in during the course of my research in 2005-2007. These negotiations centre on attempts made to reproduce certain forms of sociality that both reveal and obscure Aboriginal social relations when inscribed in the category 'Aboriginal community'. This analysis is meant to contribute to the limited anthropological research that exists on urban Aboriginal experiences generally and research conducted on Aboriginal experiences in southeastern Australia. It addresses the complex social field of Aboriginal community-making practices that exist in Australia where Aboriginal and non-Aboriginal Australians are located within the bureaucratic structures of the state, institutional networks, as well as non-government community organisations. This research contributes to understanding 'the institutional construction of indigeneity' (Weiner 2006: 19) and how this informs the (re)development of urban Aboriginal communities.

Full textAbstract:
The thesis outlines the development of three children’s residential institutions on the site of 200 Victoria Street, Ballarat East: the Ballarat District Orphan Asylum (1866-1909), the Ballarat Orphanage (1909-1968), and the Ballarat Children’s Home (1968-1983). These institutions are the historical precursors to the contemporary community service organisation now known as Child and Family Services Ballarat, or simply Cafs. The thesis focuses particularly on the shifting cultures of these institutions, to identify waves of change, surging and receding to form long patterns of alternating reform and repose. Established ways of operating overlapped with new and developing ideas, to create a dynamic environment constantly negotiating its relationships with government, communities and of course the families and children who came to rely on them. As a result, when transformative change occurred, it was difficult for leaders and policy-makers to recognise it as such at the time, as it was often experienced more as crisis and response. This provides a useful set of historical examples for current leadership and practitioners to learn from. Most critically, however, it locates the thousands of children who were institutionalised - eating, sleeping, playing, learning and working – as central to the narrative formation of identity for the historic institutions themselves, the contemporary organisation they have become, and the communities of Ballarat and beyond. Children were sent to these institutions from all over Victoria and Australia and made their homes in many different places when they left. Nevertheless, the stories and lives of the children from these institutions and the adults they have become are a key part of contemporary collective identity. The institutions are remembered with complex and contradictory mixtures of regret, loss, trauma and fondness, reflecting the mixed legacies that these institutions have left in contemporary Ballarat and beyond.Doctor of Philosophy

Full textAbstract:
This dissertation reports the application of nonlinear optical effects for the investigation of vibrational and electronic spectroscopy of molecules adsorbed on thin film metal oxide surfaces and metal oxide surfaces. The main emphasis of the experiments cited here is to introduce the recently developed multi-photon technique, Waveguide Surface Coherent anti-Stokes Raman Scattering Spectroscopy (WSCARS), to the scientific community. Planar optical waveguides have been utilized to generate large optical field enhancements on metal oxide surfaces. Guided waves have been employed to obtain the surface coherent anti-Stokes Raman scattering spectra of pyridine, phenol, benzene, methanol, CD₃OD, 2,4-pentadione, oxygen, ammonia and ND₃ adsorbed onto a ZnO (0001) surface. Vibrational spectra of transient species (O₂⁻) adsorbed on ZnO (0001) surface are also presented. Furthermore, the WSCARS has been used to monitor catalytic hydrogenation of ethylene adsorbed on ZnO (0001) surface. The WSCARS technique is compared with the other vibrational surface probes. Future directions and limitations of the technique are also discussed. Electronic spectra of surface bound species have been examined by resonantly enhanced surface second harmonic generation (SSHG). SHG spectra of trans-cinnamic acid adsorbed on optically cleaned fused silica have been obtained at room temperature and at 4 K. Surface second harmonic generation has been applied to study the adsorption of water and acetone onto thermally grown silicon dioxide/silicon surface. SSHG has been successfully applied to monitor photo-oxidation and photo-reduction of a rutile (110) surface. Experiments are described, data are presented, and surface-adsorbate binding modes are discussed.

Resumo: Técnicas de microscopias ópticas são as principais ferramentas capazes de observar células e tecidos biológicos em tempo real e com mínimo dano. Essa área foi revolucionada recentemente através das microscopias confocais de varredura a laser e as microscopias de óptica não linear, naturalmente confocais. Entre os processos não lineares temos, a fluorescência excitada por dois ou mais fótons, geração de segundo harmônico [Second Harmonic Generation - SHG] e terceiro harmônico [Third Harmonic Generation - THG]. SHG e THG são técnicas de óptica não linear coerentes, não necessitam de marcadores exógenos e permitem reconstrução de imagens em três dimensões com resolução espacial subcelular. As técnicas de fluorescência permitem visualizar estruturas específicas no espaço, mas não permitem discriminar as substâncias químicas nas estruturas celulares, e as técnicas de SHG e THG não possuem especificidade química. Espectroscopia Raman possui especificidade química através das propriedades vibracionais das moléculas e pode ser usada como mecanismo de contraste na aquisição de imagens. Comparada com a espectroscopia/microscopia infravermelho, a microscopia Raman traz a informação das vibrações moleculares do infravermelho para o visível, eliminando os problemas da baixa resolução espacial e opacidade das amostras. Entretanto a baixa sensibilidade dessa técnica implica em tempos de aquisição de imagens muito longos, da ordem de horas, inviabilizando acompanhar a dinâmica de processos celulares em tempo real. Como solução para essa baixa sensibilidade do espalhamento Raman espontâneo, surgiu a microscopia por espalhamento Raman Coerente anti-Stokes [Coherent Anti-Stokes Raman Scattering - CARS]. Comparado com Raman espontâneo, a microscopia CARS representa aumento de 4 a 5 ordens de grandeza na sensitividade da técnica, diminuindo os tempos de aquisição ao ponto de viabilizar a aquisição em taxas de vídeos (mais rápido do que 30 quadros por segundo) e estudos em tempo real. Essa tese é dedicada ao estudo experimental e teórico, assim como de algumas aplicações, das técnicas de óptica não linear, com destaque para processos de óptica não linear coerentes. Apresentamos de forma detalhada três sistemas experimentais para a aquisição de imagens de Raman coerente e um sistema integrado com várias técnicas de óptica não linear. Mostramos as primeiras imagens de CARS realizadas no Brasil. Além do CARS convencional, trabalhamos com outra técnica de CARS de ordem mais alta, o CARS cascata [cascade CARS - CCARS], e, no melhor do nosso conhecimento, apresentamos as primeiras imagens internacionais obtidas com essa metodologia. CCARS aumenta o contraste da técnica CARS, diminuindo o fundo não ressonante, um problema que aflige a comunidade científica dedicada ao uso dessa técnica. Além da diminuição do fundo não ressonante, a emissão do CCARS acontece em um comprimento de onda diferente de qualquer outro efeito não linear coerente, significando um acréscimo de complexidade mínimo para sua detecção quando comparado com o CARS. Por último mostramos algumas aplicações realizadas com o sistema experimental desenvolvido para integrar diversas modalidades ópticas em paralelo, especialmente da geração de harmônicos com a fluorescência excitada por dois fótons e suas variantes, como microscopia de tempo de vida de fluorescência (Fluorescence Lifetime Imaging ¿ FLIM)
Abstract: Optical microscopies techniques are the main tools capable of observing cell and biological tissues in real time and with minimum damage. This area have recently been revolutionized by confocal laser scanning microscopies and non-linear microscopies, naturally confocal. Among the non-linear process we have, the two or more photons excited fluorescence, second harmonic generation [SHG] and third harmonic generation [THG]. SHG and THG are coherent nonlinear techniques, they do not require exogenous markers and allow three dimension imaging reconstruction with subcellular resolution. The fluorescence techniques allow visualizing specific structures in space, but do not allow discriminating the chemical substances in cellular structures, SHG and THG techniques do not have chemical specificity. Raman spectroscopy has chemical specificity through the vibrational properties of the molecules and can be used as a contrast mechanism for imaging acquisition. Compared to infrared spectroscopy/microscopy, Raman microscopy brings information about molecular vibration from infrared to visible, eliminating the low resolution and sample opacity problems. However, this technique low sensibility implies in very long imaging acquisition times, order of hours, making it not viable for following cellular process dynamics in real time. As an answer for the spontaneous Raman scattering low sensibility, the coherent anti-Stokes Raman scattering [CARS] emerged. Compared to spontaneous Raman, CARS microscopy presents an increase of 4 to 5 orders of magnitude in the sensitivity of the technique, lowering the acquisition times to the point of making video acquisition (faster than 30 frames per second) and real time studies possible. This thesis is dedicated to the experimental and theoretical study, as well as some applications, of the non-linear techniques, with emphasis on coherent non-linear optical processes. We present in detailed form three experimental systems for the acquisition of coherent Raman images, and a system with the integration of various non-linear techniques. We show the first CARS images acquired in Brazil. In addition to conventional CARS, we worked with other higher order CARS technique, the cascade CARS [CCARS], and, in the best of our knowledge, we present the first international image acquired with this methodology. CCARS increases the contrast from CARS technique, decreasing the non-resonant background, a problem that afflicts the scientific community dedicated to the use of this technique. Besides the decrease of the non-resonant background, the CCARS emission occurs in a different wavelength from any other non-linear coherent effect, meaning a minimum complexity increase for its detection when compared with CARS. Finally we show some applications performed with the experimental system developed to integrate several optical modalities in parallel, especially the generation of harmonics with two photons excitation fluorescence and their variants such as Fluorescence Lifetime Imaging [FLIM]

Este trabalho trata da elaboração de um aplicativo computacional em Visual Basic capaz de gerar malhas estruturadas e não estruturadas sobre domínios bidimensionais multiplamente conexos. Esta geração deverá ocorrer de modo bastante automático com pouca intervenção do usuário, a qual será efetuada através de uma interface gráfica amigável. Para armazenamento das malhas definiu-se uma estrutura de dados de fácil compatibilidade com aplicativos computacionais baseados no método dos elementos finitos para solução de problemas do tipo convectivo-difusivo. Os tipos de células (elementos finitos) que foram implementadas são: células triangulares lineares e células quadrilaterais quadráticas. Adicionalmente gerou-se malhas bidimensionais para solução de problemas clássicos do tipo convectivo-difusivo, utilizando-se códigos de elementos finitos já desenvolvidos por pesquisadores do grupo de pesquisa.
The mesh generation is needed in many applications of numerical methods such as finite difference, finite volume and finite element methods. In this work the algebraic method has been applied to generate 2D structured and unstructured mesh of quadrilateral and triangular elements by using Visual Basic. Both linear and quadratic elements can be generated. The connectivity, the nodes coordinates and contour nodes can be saved in an automatic way for a posterior use in, for example, a solver of finite element methods. A friendly interface has been developed for easy usage by users. Some tests have been done in applications of convective-diffusive fluid flows problems using solvers previously constructed, based on finite elements methods to demonstrate the capabilities of the mesh generator.

A mathematical model is developed for investigating time dependent surface deformations of a hydrostatic water volume, when it is subjected to a sudden partial rise of the sea bottom.
In the model, 2-dimensional, compressible, and viscous Navier-Stokes equations are solved by Marker and Cell (MAC) method. Variable mesh size in both horizontal and vertical directions with a staggered grid arrangement is used. Limited compressibility model is utilized for pressure. Various computational tests are done for the selection of computational parameters of the model. It is found that the amplitude of surface waves generated by vertical displacements of the sea bottom depends on size and speed of bottom displacements.

Os tipos de células (elementos finitos) que foram implementadas são: células triangulares lineares e células quadrilaterais quadráticas. Adicionalmente gerou-se malhas bidimensionais para solução de problemas clássicos do tipo convectivo-difusivo, utilizando-se códigos de elementos finitos já desenvolvidos por pesquisadores do grupo de pesquisa.Abstract: The mesh generation is needed in many applications of numerical methods such as finite difference, finite volume and finite element methods. In this work the algebraic method has been applied to generate 2D structured and unstructured mesh of quadrilateral and triangular elements by using Visual Basic. Both linear and quadratic elements can be generated. The connectivity, the nodes coordinates and contour nodes can be saved in an automatic way for a posterior use in, for example, a solver of finite element methods. A friendly interface has been developed for easy usage by users. Some tests have been done in applications of convective-diffusive fluid flows problems using solvers previously constructed, based on finite elements methods to demonstrate the capabilities of the mesh generator.

Full textAbstract:
This thesis critically analyses sperm donation practices from a child-centred perspective. It examines the effects, both personal and social, of disrupting the unity of biological and social relatedness in families affected by donor conception. It examines how disruption is facilitated by a process of mediation which is detailed using a model provided by Sunderland (2002). This model identifies mediating movements - alienation, translation, re-contextualisation and absorption - which help to explain the powerful and dominating material, and social and political processes which occur in biotechnology, or in reproductive technology in this case. The understanding of such movements and mediation of meanings is inspired by the complementary work of Silverstone (1999) and Sunderland. This model allows for a more critical appreciation of the movement of meaning from previously inalienable aspects of life to alienable products through biotechnology (Sunderland, 2002). Once this mediation in donor conception is subjected to critical examination here, it is then approached from different angles of investigation.
The thesis posits that two conflicting notions of the self are being applied to fertility-frustrated adults and the offspring of reproductive interventions. Adults using reproductive interventions receive support to maximise their genetic continuity, but in so doing they create and dismiss the corresponding genetic discontinuity produced for the offspring. The offspring’s kinship and identity are then framed through an experimental postmodernist notion, presenting them as social rather than innate constructs. The adults using the reproductive intervention, on the other hand, have their identity and kinship continuity framed and supported as normative, innate, and based on genetic connection. This use of shifting frameworks is presented as unjust and harmful, creating double standards and a corrosion of kinship values, connection and intelligibility between generations; indeed, it is put forward as adult-centric.
The analysis of other forms of human kinship dislocation provided by this thesis explores an under-utilised resource which is used to counter the commonly held opinion that any disruption of social and genetic relatedness for donor offspring is insignificant. The experiences of adoption and the stolen generations are used to inform understanding of the personal and social effects of such kinship disruption and potential reunion for donor offspring. These examples, along with laws governing international human rights, further strengthen the appeal here for normative principles and protections based on collective knowledge and standards to be applied to children of reproductive technology.
The thesis presents the argument that the framing and regulation of reproductive technology is excessively influenced by industry providers and users. The interests of these parties collide with and corrode any accurate assessments and protections afforded to the children of reproductive technology. The thesis seeks to counter such encroachments and concludes by presenting these protections, frameworks, and human experiences as resources which can help to address the problems created for the offspring of such reproductive interventions, thereby illustrating why these reproductive interventions should be discontinued.

Full textAbstract:
Articular cartilage has been imaged using the following multi-photon modalities: Second Harmonic Generation (SHG), Two-photon Fluorescence (TPF) and Coherent Anti-Stokes Raman Scattering (CARS). A simple epi detection microscope was constructed for SHG and TPF imaging in the early stages of this research. Later the imaging was transferred to a new microscope system which allowed simultaneous forwards and epi detection and combined CARS imaging with TPF and SHG. Multiphoton spectroscopic studies were conducted on both intact tissue samples and the major components of the extracellular matrix, in order to identify sources of TPF. Fluorescence was detected from type II collagen, elastin and samples of purified collagen and elastin crosslinks. Age related glycation crosslinks of collagen may be a significant source of TPF. No fluorescence was detected from proteoglycans. In intact, unfixed healthy articular cartilage the cells were observed via CARS, surrounded in their pericellular matrix which is characterised by an increase in TPF. The collagen of the extra cellular matrix showed up clearly in the SHG images. Diseased cartilage was also imaged revealing microscopic lesion at the articular surface in early osteoarthritis and highly fibrous collagen structures and cell clusters in more advanced degeneration. In young healthy cartilage a network of elastin fibres were found lying parallel to the articular surface in the most superficial 50μm of the tissue. Regional variations in these fibres were also investigated. The fibres appeared mainly long and straight suggesting that they may be under tension, further work is needed to identify whether they have a mechanical function. The polarization sensitivity of the SHG from collagen has been investigated for both cartilage and tendon. In the most superficial tissue these measurements can be used directly to determine the collagen fibre orientation. However at increasing depths the effects of biattenuation and birefringence must be considered. Healthy cartilage has a characteristic pattern of polarization sensitivity with depth and this changes at lesions indicating a disruption of the normal collagen architecture. The methods developed in this thesis demonstrate the use of non-linear microscopy to visualise the structure of the extracellular matrix and cells in intact unstained tissue. They should also be appropriate in many areas of cell and matrix biology.

Full textAbstract:
Nonlinear optical microscopy is a collection of very powerful imaging techniques. Linear optical microscopes probe the refractive index and absorption, which both stem from the first-order linear electric susceptibility. Especially in biological tissue, the variation in the refractive index is often small and the tissue is, in many cases, transparant. Nonlinear optical microscopes on the other hand probe the nonlinear higher-order susceptibilities, which can be chemically sensitive, leading to the capability to achieve label-free imaging.
Nonlinear optical microscopes have been in development for more than thirty years and they are based on numerous nonlinear optical processes. The ones I will concentrate on in this thesis are second harmonic generation (SHG), coherent anti-Stokes Raman scattering (CARS), and stimulated Raman Scattering (SRS). The first technique is commonly used to image collagen as those molecules have a particularly large second-order nonlinear susceptibility due to their chiral structure. CARS and SRS on the other hand are often used because they resonantly target vibrational resonances in molecules, giving rise to the aforementioned label-free imaging.
Deep understanding of the nonlinear imaging process is crucial to the interpretation of the images these techniques produce. Computational tools are exceptionally suited for this task as they allow studying the electromagnetic field anywhere in the sample as well as the far-field, and one can change any of the material properties to study their effect. One such tool is finite-difference time-domain (FDTD) that our group developed for nonlinear optical microscopy simulations. It is a direct discretization of Maxwell's equation. While computationally costly, it does allow any arbitrary shaped sample to be simulated. The sample can have frequency dependent refractive indexes, and also nonlinear media with third-order nonlinearities such as Kerr media and Raman-active media, but also second-order nonlinearities for SHG. The code is designed in such a way that it can run on thousands of CPUs on a wide variety of compute cluster which allows our group to obtain nanoscale resolution.
Another computational tool I use is the free-space Green's function solution to the Helmholtz equation, which can be used to calculate the Hertz vector in the frequency domain, both in the near- and far-field, based on the induced nonlinear polarization. The electric field is then calculated from this Hertz vector. This technique is much faster then FDTD and also allows for arbitrary shapes of the nonlinear electric susceptibility in the sample. However, it assumes a homogeneous refractive index throughout the entire spatial domain and requires complete knowledge of the input beam or beams that induce the nonlinear polarization.
In this thesis, I use these tools to study the image formation process of various nonlinear optical processes mentioned earlier. For example, I study the effect of an inhomogeneous refractive index on the images produced by these microscopes. In literature the index of refraction is almost always assumed to be homogeneous, because, as mentioned before, the inhomogeneity of the refractive index is often small. However, I show that these small differences in the index of refraction can have a significant effect on the measured far-field intensity signal. For example, in SRS and CARS images, the measured signal can increase by an order of magnitude depending on the index mismatch and structure of the sample. Additionally, significant shifts in perceived position occur. Even nonresonant nonlinear signals can be evoked purely through a mismatch in linear refractive index.
Computational modelling can also help reveal additional detail. As SHG is a coherent process, subwavelength information can be inferred through the phase information. Our experimental collaborators built an interferometric SHG (I-SHG) microscope for exactly that purpose. We used this to image collagen fibrils, which are all aligned in a parallel fashion. However, because collagen fibrils have a chiral molecular structure, they can point either ``up'' or ``down''. Using my Green's function simulations of the SHG imaging process of collagen fibrils, I was able to predict the standard deviation in the measured phase and link it to the orientation of collagen fibrils in the focal spot of the probing laser beam, even though the diameters are far below the minimum resolvable capabilities of the microscope. We found that the ``upwards'' fibrils make up 46--53% of the sample.
Even with a normal SHG microscope that does not measures phase, additional subresolution information is obtainable. With our collaborators we measured the ratio of the forward SHG intensity signal to that in the backward direction and with my simulations, we are able to link this to the fibril diameters in collagen tissue. Thus we inferred that the fibril diameter increases as a function of tissue depth.
Furthermore, a computational technique called ptychography is able to retrieve phase information without an interferometric reference beam. Additionally, it increases resolution to the theoretical limit, independent of the laser focal spot size, and corrects for distortions in the input beam as well. I have developed this technique for use with nonlinear optical microscopy and was able to show it is a viable alternative to I-SHG by imaging simulated rat tail tendon at the diffraction limit while retrieving the orientation of the fibrils through the phase of the SHG signal. I also implemented the algorithm for CARS, where the phase information can be used to greatly increase the signal-to-noise ratio by reducing the nonresonant background radiation that results from competing nonlinear optical processes. I showed an example of this by imaging a simulated fibroblast cell where the CARS process was tuned to the lipid droplets inside of the cell. I am currently in talk with experimentalists to apply this theoretical technique to experiments as that would further demonstrate the impact of my work.
Finally, keeping in theme with the collagen fibrils, I show that the ratio of the forward SHG signal to the backward signal, the F/B ratio, is affected by a mismatch in the refractive index for fibrils larger than 100nm. This measure is an indicator of fibril diameter and thus important for making qualitative predictions. Single fibrils are generally too small to be significantly affected by near-field effects, but the bigger fibrils can be. Fibrils in rat tail tendon have a distribution of fibrils diameters and the large fibrils occur infrequent. However, I found that the large fibrils are largely responsible for the forward as well as backward signal, thus refractive index mismatches still affect the F/B ratio significantly despite their infrequency. The F/B ratio for a collection of fibrils placed in a n=1.47 medium was found to be 31.8±0.7% higher than for those in a n=1.33 medium. Our experimental colleagues have done preliminary measurements on mouse tail tendon where they found an increase of 40±20%, in line with the value of 28.1±0.6% that I found for simulations with mouse tail tendon.
In conclusion, the theoretical tools I have used in my thesis have provided me with the ability to study nonlinear optical image formation processes with a level of detail that would be near-impossible to do experimentally. I have used this ability to show how refractive index mismatches, such as those found in biological tissue, can significantly distort the far-field intensity signals. I have shown this for SRS and CARS where the far-field intensity signal appeared an order-of-magnitude larger compared to the same sample without a refractive index mismatch with the background medium. Additionally, shifts in the perceived position of the object under investigation were observed and I showed the presence of a nonresonant background signal in AM-SRS. Likewise I showed that in the SHG imaging of collagen fibrils significant changes in the F/B ratio can occur. All of these effects have important implications as these types of images as biomedical researches rely on the correct interpretation of nonlinear optical microscopy images for both research and diagnostics.
Apart from showing the effect of a refractive index mismatch, I have also shown that computation modelling can be used to infer subwavelength features in SHG imaging experiments of collagen fibril such as fibril orientation and fibril diameter. These methods have the potential to aid medical researchers as changes in the structure of collagen are often an early indicator of diseases such as osteoarthritis.
Finally, I showed that the ptychography algorithm I developed for nonlinear optical microscopy is able to retrieve phase information of the nonlinear electric susceptibility in SHG and CARS imaging while also enhancing the resolution and correcting for distortions in the input beams. I can also use much larger laser spot sizes than in conventional experiments without compromising the obtained resolution, thus fewer measurements are required. The technique is not limited to SHG and CARS either; it will work for other nonlinear optical processes as well. Experimental verification of nonlinear ptychography will be done soon. This technique has to potential to significantly improve current imaging techniques since access to the phase information allows one to observe additional information about the sample as we showed with the I-SHG microscope.

Full textAbstract:
Transport of solid particles in a slit virtual impactor has been analyzed using visualization techniques. Particle trajectories were observed using laser-induced fluorescence of monodisperse particles seeded in the virtual impactor flow. It was observed from these trajectories that for smaller inertia particles essentially followed the flow streamlines, whereas higher inertia particles tend to deflect from their initial streamlines. These transport characteristics were used to determine particle collection efficiency curves, and the percentage of defect particle transmission, particles transmitted to the major flow that are well beyond the experimentally determined 50% cutoff. Defect percentages were found to be in good agreement with those based on a local stokes number approach, an analytical model using a converging flow velocity profile. It was hypothesized that these defects occur by virtue of larger particles passing through the near wall flow region and consequently transported to the major flow. The trajectories of such defect occurrences clearly show that these particles originated in the near wall region. Performance at higher mass loadings was evaluated using a background dust matrix generated by a turntable aerosol generator. At high mass loadings, clogging of the slit led to the deterioration of the impactor's performance. The time taken to clog the silt was estimated by modeling the slit edge as a single filter fiber of rectangular cross section with the primary mechanism of filtration being interception and was found to be in good agreement with the experimental data. Elimination of defect transmission and clogging would be possible by the provision of a sheath airflow, which ensures that the near wall regions are free of particles.

Full textAbstract:
"Sorry" is a play in two acts, exploring how collective memory of the past, including traumatic memory of being taken from one's family, affects the present in complex and surprising ways. The Stolen Generations' episode of Australian history, when mixed heritage Aboriginal Australians were taken from their families as a result of governmental policy, casts its shadow over four generations of Almadi Paice Aboriginal-Afghan-Anglo mixed heritage family members. Against a thematic backdrop of shame, apology and (hoped for) forgiveness, the 'living' family members struggle for empowerment and agency against the forces of government bureaucracy, the Law and their own emotional demons.
"Shame and Apology in the Nation-State: Reflections and Remembrance" is an exegesis which explores theoretical concepts related to collective memory, shame, performative apology and forgiveness, interlinked with Jan Patočka's notion of individual responsibility towards action. Using reciprocal interview material with a number of Aboriginal-Afghan-Anglo mixed heritage participants, who have either had direct experience of being "stolen" or who are related to "stolen" family members, this exegesis explores alternative modes of remembering their past and present in creative art works. In addition, I theorise that in our contemporary "age of apology" political apology to particular wronged groups of national communities may be problematic not only for their ubiquity and their tendency to alibi but because they do not address other important issues such as reparation and guarantees against repetition; nor do they deny the sovereignty of the nation-state apparatus to ‘do’ apology in a manner and at a time of its own choosing. The exegesis explores the importance of national commemoration, such as ANZAC Day, in promoting national collective memory, and theorises that a collective annual commemoration on behalf of the nation’s "stolen" people would be a much more compelling reconciliatory act than a single apology by a particular prime minister. My short story, "We’re Ready", which immediately follows the exegesis is my creative attempt to demonstrate the towards action and towards national reconciliation gestured by annual commemorative performance.

Full textAbstract:
Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorUma simulação numérica que leva em conta os efeitos de estratificação e mistura escalar (como a temperatura, salinidade ou substância solúvel em água) é necessária para estudar e prever os impactos ambientais que um reservatório de usina hidrelétrica pode produzir. Este trabalho sugere uma metodologia para o estudo de escoamentos ambientais, principalmente aqueles em que o conhecimento da interação entre a estratificação e mistura pode dar noções importantes dos fenômenos que ocorrem. Por esta razão, ferramentas de simulação numérica 3D de escoamento ambiental são desenvolvidas. Um gerador de malha de tetraedros do reservatório e o modelo de turbulência algébrico baseado no número de Richardson são as principais ferramentas desenvolvidas. A principal dificuldade na geração de uma malha de tetraedros de um reservatório é a distribuição não uniforme dos pontos relacionada com a relação desproporcional entre as escalas horizontais e verticais do reservatório. Neste tipo de distribuição de pontos, o algoritmo convencional de geração de malha de tetraedros pode tornar-se instável. Por esta razão, um gerador de malha não estruturada de tetraedros é desenvolvido e a metodologia utilizada para obter elementos conformes é descrita. A geração de malha superficial de triângulos utilizando a triangulação Delaunay e a construção do tetraedros a partir da malha triangular são os principais passos para o gerador de malha. A simulação hidrodinâmica com o modelo de turbulência fornece uma ferramenta útil e computacionalmente viável para fins de engenharia. Além disso, o modelo de turbulência baseado no número de Richardson leva em conta os efeitos da interação entre turbulência e estratificação. O modelo algébrico é o mais simples entre os diversos modelos de turbulência. Mas, fornece resultados realistas com o ajuste de uma pequena quantidade de parâmetros. São incorporados os modelos de viscosidade/difusividade turbulenta para escoamento estratificado. Na aproximação das equações médias de Reynolds e transporte de escalar é utilizando o Método dos Elementos Finitos. Os termos convectivos são aproximados utilizando o método semi-Lagrangeano, e a aproximação espacial é baseada no método de Galerkin. Os resultados computacionais são comparados com os resultados disponíveis na literatura. E, finalmente, a simulação de escoamento em um braço de reservatório é apresentada.
To study and forecast the environmental impacts that a hydroelectric power plant reservoir may produce, a numerical simulation that takes into account the effects of stratification and scalar mixing (such as temperature, salinity or water-soluble substance) is required. This work proposes a methodology for the study of the environmental fluid flow phenomena, mainly for flows in which the knowledge of the interaction between stratification and mixing can give important notions of the phenomena that occur. For this, a numerical simulation tool for 3D environmental flow is developed. A tetrahedral mesh generator of the reservoir based on the terrain topology and an algebraic turbulence model based on the Richardson number are the main tools developed. The main difficulty in tetrahedral mesh generation of a reservoir is nonuniform distribution of the points related to the huge ratio between the horizontal and vertical scales of the reservoir. In this type of point distributions, conventional tetrahedron mesh generation algorithm may become unstable. For this reason, a unstructured tetrahedral mesh generator is developed and the methodology used to obtain conforming elements is described. Triangular surface mesh generation using the Delaunay triangulation and the construction of the tetrahedra from the triangular surface mesh are the main steps to the mesh generator. The hydrodynamic simulation of reservoirs with a turbulence model provides a useful tool that is computationally viable for engineering purposes. Furthermore, the turbulence model based on the Richardson number takes into account the effects of interaction between turbulence and stratification. The algebraic model is the simplest among the various models of turbulence, but provides realistic results with the fitting of a small amount of parameters. Eddy-Viscosity/Diffusivity models for stratified turbulent flows models are incorporated. Using the Finite Element Method (FEM) approximation the Reynolds-averaged Navier-Stokes (RANS) and mean scalar transport equations are approximated. The convective terms are discretized employing the Semi-Lagrangian method, and the spatial discretization is based on the Galerkin method. The computational results are compared with the results available in the literature. Finally, the simulation of the flow in a branch of a reservoir is presented.

Full textAbstract:
In August 2000, Justice O�Loughlin of the Federal Court of Australia handed down the decision in Cubillo v Commonwealth in which Lorna Cubillo and Peter Gunner took action against the Commonwealth Government, arguing that it was vicariously liable for their removal from their families and communities as children and subsequent detentions in the Northern Territory during the 1940s and 1950s. The case is the landmark decision in relation to legal action taken by members of the Stolen Generations.
Using the decision in Cubillo as a key site of contestation, my thesis provides a critique of legal positivism as the dominant jurisprudential discourse operating within the Anglo-Australian legal system. I argue that the function of legal positivism as the principal paradigm and source of authority for the decision serves to ensure that the debate concerning reconciliation in Australia operates rhetorically to maintain whiteness at the centre of political and discursive power. Specifically concerned with the performative function of legal discourse, the thesis is an interrogation of the interface of law and language, of rhetoric, and the semiotics of legal discourse.
The dominant theory of evidence law is a rationalist and empiricist epistemology in which oral testimony and documentary evidence are regarded as mediating the relationship between proof and truth. I argue that by attributing primacy to principles of rationality, objectivity and narrative coherence, and by privileging that which is visually represented, the decision serves an ideological purpose which diminishes the significance of race in the construction of knowledge.
Legal positivism identifies the knowing subject and the object of knowledge as discrete entities. However, I argue that in Cubillo, Justice O�Loughlin inscribes himself into the text of the judgment and in doing so, reveals the way in which textual and corporeal specificities undermine the pretence of objective judgment and therefore the source of judicial authority.

Ce travail propose une méthodologie de couplage bidirectionnel entre un modèle Navier-Stokes et un modèle fluide parfait potentiel pour des applications d’ingénierie marine et particulièrement d’interaction houlestructure. Les quantités d’intérêt sont décomposées comme la somme d’un terme d’écoulement incident et un terme d’écoulement complémentaire. Un modèle potentiel non-linéaire (HOS : High-Order Spectral) est utilisé pour l’écoulement incident. L’écoulement complémentaire est traité par des modèles de fluide visqueux et de fluide parfait potentiel. Le modèle fluide visqueux est basé sur les équations SWENS (Spectral Wave Explicit Navier-Stokes) et une formulation de type Level-Set pour la prise en compte de l’interface; ce modèle est utilisé dans un domaine proche de la structure marine étudiée. Le modèle de fluide potentiel est un modèle linéarisé basé sur une description de Poincaré. Cette description est utilisée pour effectuer de nouveaux développements où la surface de couplage est un cylindre circulaire, ce qui permet de résoudre les problèmes de divergence numérique rencontrés initialement sur la surface libre. Les variables utilisées pour le couplage entre les deux modèles sont la vitesse du fluide et l’élévation de surface libre. Le couplage proposé est validé pour des cas de diffraction-radiation et l’accord avec les résultats de référence est bon. En particulier, les efforts du 1er et du 2ème ordre sont bien restituésThe present study proposes a two-way coupling methodology between potential and viscous flow models for a marine application. A hypothesis that the functional quantities of total flow can be decomposed into the incident and complementary parts is assumed. The nonlinear potential flow model for incident flow is available. Therefore the complementary flow is only concerned in the potential and viscous flow models. The computational domain for complementary flow is decomposed. In the vicinity of structure, the viscous flow model based on Spectral Wave Explicit Navier-Stoke Equations (SWENSE) is used. A linear potential flow model based on Poincaré velocity representation is applied to simulate the complementary wave in the far-field. The fluid velocity and wave elevation are used to couple the potential and viscous flow models. A preliminary study on the coupling is conducted and the necessity to a fast evaluation of potential flow is raised. The nonlinear potential flow models for incident waves are summarized and the reconstruction procedure in the viscous flow solver is proposed and validated with the simulation and experiments. A new Poincaré’s velocity representation for time domain free surface flow is introduced with a circular cylindrical matching surface. The proposed representation is validated with the linear radiation-diffraction problem and the results show good agreements. The viscous flow solver based on SWENSE method with Level-Set interface modeling is proposed. The potential and viscous flow models are coupled and the results show that the coupling can enhance the first- and second-order forces acting on the structure

This thesis presents the combination of my lived experience as a child of the Stolen Generations, and an analysis of the relationships between church, state, and anthropologist A.P. Elkin and the roles they played across the 1920s, 1930s and 1940s in laying the foundations for assimilation and mission endeavour around half-castes which shaped my experience. Interrogation of archival documents reveals a multi-layered history beginning in the late 1920s which led to the setting up in 1941 of the Methodist Overseas Mission of Croker Island the purpose of which was assimilation of Northern Territory half-caste children. Working from the Aboriginal knowledge position, the thesis is written through feminist standpoint theory. Through employing the methodology of bricolage, and incorporating a range of mediums including spoken word personal reflection primary source documents are interrogated through my personal story. The thesis undertakes an in-depth analysis of the ways ‘science’, both national and international, was applied to early to mid-twentieth century constructions of full-blood and half-caste Aboriginal people as a ‘race’. This analysis is then applied to the broad national discourse on prospective mission, policy and anthropological solutions to what had become known as the ‘half-caste problem’. Demonstrating the impacts of these solutions, the discussion focuses on the development of the Methodist Overseas Mission of Croker Island. This is followed by the presentation of a personal case-study which details the actions, reports and decisions taken by Northern Territory Welfare Department agents and members of the State Children’s Council leading to the removal of six half-caste children from their family. The analysis concludes with a discussion on the current state of Aboriginal and Torres Strait Islander health, and the prevailing levels of intergenerational trauma identified as arising from Aboriginal child removal in the twentieth century.Thesis (Ph.D.) -- University of Adelaide, School of Humanities, 2018

It is the main premise in this thesis that there was a deliberate process of disturbing the body, minds or psyche as well as the lived culture of these women. Hence, through body, mind as well as cultural dysphoria, Stolen Generations are challenged to construct an identity.

Dermatological diagnosis is usually done by visual examination or detailed biopsies with microscopy on the targeted specimen. The processes usually lack quantitative analysis, and may be time consuming if tissue culturing is required. This study focuses on the biopsy of scar tissues of human skin, including normal, hypertrophic, and keloid tissues, by analyzing the polarization states of second harmonic signals from the tissues with the novel four-channel Stokes’ polarimeter. A mode-locked Ti-sapphire laser, which generated 200 fs ultra-short pulses, is used to induce second harmonic signal from the collagen of the skin tissues. In this way, the potential photo-toxicity on fluorophores is greatly reduced. The samples are irradiated with the incident beam of various polarization states. The resulting polarization parameters reconstructed from the SHG signals reveal unique collagen arrangements in the tissues. Our results show that the different skin lesions are clearly distinguishable through the polarization imaging of the collagen structure. The noninvasive and enhanced contrast enabled by polarization has the potential for in-depth biomedical analysis and may find invaluable applications in clinical diagnosis.

Starch is one of the major components in our daily diet. It is also a natural second harmonic (SH) generator, with amylopectin as the active component. The molecular structure and optical activity of starch may well be reflected by SH. In this work, we investigated the polarization states of SH from starch by 4-channel based Stokes’ polarimeter. The change of SH and its polarization states are monitored throughout the denaturation processes for both dry and hydrated starch. It was found that SH disappears at the gelatinization temperature. The results are consistent with those from differential scanning calorimeter (DSC) and the loss of birefringence from hydrated starch during heating. For comparison, SH from dry starch decreases gradually. When comparing the data of DSC and SH from starch during heating, the endothermic peak at 65 degree is observed for hydrated starch, at which the intermolecular bonds in amylopectin are broken down to result in the disruption of the concentric symmetrical structure. The change in structure is reflected by SH and the corresponding polarization states and is verified by scanning electric microscopy (SEM). In SEM micrographs, the dry starch granules show only destroyed surface, while the hydrated ones exhibits near total disintegration of granular structures due to gelatinization, reflecting the fact that water is crucial for the cooking of rice.

This dissertation presented an investigation on the method of internal generation of waves and currents for three-dimensional (3D) Navier-Stokes equations models to enhance the model's capacity to simulate wave-current-structure interaction issues. The development of the proposed method could be divided into four steps: wave generation and absorption for two-dimensional (2D) wave tank, generation of directional waves for 3D wave flume, generation of wave-current, and applications for coastal/ocean engineering. The 3D numerical model FLOW-3D which solves the Navier-Stokes type equations and captures the water surface elevation by the volume of fluid method was utilized in this study. FLOW-3D was employed to investigate the mass source internal wavemaker and the numerical sponge layer. Besides, the wave-generating and-absorbing method was extended to generate currents. The problems of wave-structure interactions and wave-current interactions were considered to evaluate the ability of the proposed method. Finally, a buoyant round jet in a wave environment was studied in detail as a topic for the application. The methodology of a directional wave-current numerical tank for a 3D Navier-Stokes equations model was established. To start with, a mass source wavemaker and a numerical sponge layer were embedded. The capability of the numerical sponge layer was first examined and an optimal layout of the sponge layer was determined based on a series of 2D numerical experiments. The scheme was successfully extended to 3D geometry. Nest, an approach for designing the mass source function was developed. Regular, irregular, and solitary waves were examined. The numerical results were compared with the analytical solutions and some numerical results obtained using the momentum source method, with good agreements observed for a wide range of relative water depths. The proposed method was applied to directional wave cases and various layouts of the source line were discussed. Also, the wave-current generation method is proposed by including the idea of the relaxation method. Finally, the proposed model was applied to simulate 2D and 3D wave-structure interaction problems. Model-data comparisons showed that the proposed method is potentially useful and efficient for examining wave-structure interactions. The numerical study on the kinematics of buoyant round jets in a wave environment was presented. A buoyant round jet was horizontally discharged at the mid-depth in regular waves. Three kinds of effluent with various densities were used for the jets. The numerical results were compared with the experimental data, with reasonable agreement observed. The mechanism of the jet oscillation under different wave-to-jet momentum ratios was presented. The effects of relative water depth, the ratio of the wave height to the water depth, and buoyancy on jet diffusion were considered. Among them, the ratio of the wave height to the water depth appeared to be the most critical factor on jet diffusion processes under the conditions being considered. Finally, the variations of the jet cross-sectional profiles in the potential core region and the near field region were studied.

Numerical solutions of the Navier-Stokes Equations became more popular in recent decades with increasingly accessible and powerful computational resources. Simulations in reconstructed or artificial pore geometries are often performed to gain insight into microscopic fluid flow structures or are used for upscaling quantities of interest, like hydraulic conductivity. A physically adequate representation of pore-scale flow fields requires analysis of large domains.
We solve the incompressible NSE in artificial ordered and random pore-space structures. A simple cubic and face-centred packings of spheres placed in a square duct are analysed. For the fluid flow simulations of random media, packings of spheres, icosahedra, and cubes forming unconsolidated sediments are generated using a rigid body simulation software. The Direct Numerical Simulation method is used for the solution of the NSE implemented in the open-source computational fluid dynamics software OpenFOAM.
The influence of the number of spheres in ordered packings, the mesh type, and the mesh resolution is investigated for fluid flow up to Reynolds numbers of 100 based on the spheres' diameter. The random media mesh generation method relies on approximate surface reconstruction. The resulting tetrahedral meshes are then used for steady-state simulations and refined based on an a-posteriori error estimator.
The fluid flow simulation results can further be used twofold:
1) They provide homogenized hydro-mechanical properties of the analysed medium for the larger meso and macro groundwater flow simulations. A concept of one-way binding for large-scale simulations is presented.
2) Visualisation: A post-processing image rendering technique was employed in interactive and still image visualisation environments allowing better overview over local fluid flow structures.
The ogs FEM code for the solution of large-scale groundwater processes was inspected for computational efficiency. The conclusions drawn from this analysis formed the~basis for the implementation of the~new version of the code---ogs6. The improvements include comparison of linear algebra software realisations and an implementation of optimized memory access patterns in FEM-local assembler part.

My novel The Heaven I Swallowed tells the story of Grace Teresa Mary McAllister, a World War II widow who decides to “save” a young Aboriginal girl, Mary, by adopting her into her home, believing she will be able to redeem the child by giving her all the benefits of white society. In Part I of the novel Mary arrives and it soon becomes obvious that her presence is bringing back the deceptions in Grace’s past. In Part II five years have passed and Grace is struggling to cope with the way she treated Mary. Exploring the myth of “for their own good” The Heaven I Swallowed is a tale of the Stolen Generations, told from the perspective of the white perpetrator. The exegesis accompanying the novel, ‘Whose Shoes? Writing The Heaven I Swallowed’, is also divided into two parts. Part I traces my awareness of the Stolen Generation stories and the reasoning behind the decision to narratively take the perspective of a white woman who steals an Aboriginal child. In Part II, I turn to two contemporary literary texts – Kate Grenville’s The Secret River and Gail Jones’s Sorry – to examine different strategies that the non-indigenous writer might employ to counter-act stereotypical representation of Aboriginality. Further analysis of the novel in the lead up to the final draft is then aided by another two texts: Elizabeth Jolley’s The Well and Joyce Carol Oates’s Black Girl/ White Girl. Using these as models – one in regards to a Gothic re-rendering of the work and the other in regards to the depiction of ambiguous race relations – I find a way to reconcile myself with the representation of Aboriginality in The Heaven I Swallowed. Finally, I come to the conclusion that the novelist might often travel a great deal away from their original intent but that these footsteps have to be taken to ensure motivations are justified and one’s conscience is at ease.Thesis (Ph.D. ) - University of Adelaide, School of Humanities, 2009

Using deep ultraviolet/vacuum ultraviolet light (DUV/VUV) as a universal probing method to ionize the photoexcited reactants and photofragments is beneficial in the photodissociation dynamics studies. Since it avoids the restricted probing Frank-Condon region of excited reactants and the cracking of photofragments in the utilizing of UV multi-photoionization. However, the low photon flux and narrow wavelength tunability of VUV light are still challenging for laser based VUV light source to be applied in the ionization of dilute and various photoproducts. Here, we set-up a vacuum pumped optical system for the generation of DUV/VUV lights by anti-Stokes Raman shifting of Nd:YAG laser in hydrogen gas. Both the high photon flux and broad wavelength tunability are achieved in the designed optical system. Furthermore, we compose the optical delayed pump-probe light path for applying this system to the picosecond time-resolved pump-probe experiment.

The thesis is dealing with the term "representation of historian" on the example of czechoslovakian historiography of the first half of twentieth century. For understanding of this work is important the context of my bachelor thesis, which dealed with the same problem using quantitative approaches on Kulturní adresář (Culture adressary) written by Antonín Dolenský. This thesis is an antropologization of the same issue in the meaning og underscoring the multiplicity of representations and its independence on the macroperspective of usual interpretations of czechoslovakian historiography. This perspective is enabled by choosen sources, which are texts of three historians - schoolmates, who studied together field of study history - geography on the Faculty of arts of Charles university.

Full textAbstract:
When the Human Rights and Equal Opportunities Commission tabled Bringing them home, its report into the separation of indigenous children from their families, it was criticised for failing to consider Indigenous child welfare within the context of contemporary standards. Non-Indigenous people who had experienced out-of-home care also questioned why their stories were not recognised. This thesis addresses those concerns, examining the origins and history of the welfare systems of NSW and Tasmania between 1880 and 1940. Tasmania, which had no specific policies on race or Indigenous children, provides fruitful ground for comparison with NSW, which had separate welfare systems for children defined as Indigenous and non-Indigenous. This thesis draws on the records of these systems to examine the gaps between ideology and policy and practice. The development of welfare systems was uneven, but there are clear trends. In the years 1880 to 1940 non-Indigenous welfare systems placed their faith in boarding-out (fostering) as the most humane method of caring for neglected and destitute children, although institutions and juvenile apprenticeship were never supplanted by fostering. Concepts of child welfare shifted from charity to welfare; that is, from simple removal to social interventions that would assist children's reform. These included education, and techniques to enlist the support of the child's family in its reform. The numbers of non-Indigenous children taken into care were reduced by economic and environmental measures, such as payments to single mothers. The NSW Aborigines Protection Board dismissed boarding-out as an option for Indigenous children and applied older methods, of institutionalisation and apprenticeship, to children it removed from reserves. As non-Indigenous welfare systems in both states were refined, the Protection Board clung to its original methods. It focussed on older children, whilst allowing reserves to deteriorate, and reducing the rights of Aboriginal people. This cannot simply be explained by race, for Tasmania did not adopt the same response. This study shows that the policies of the Aborigines Protection Board were not consonant with wider standards in child welfare of the time. However, the common thread between Indigenous and non-Indigenous child removal was the longing of children and their families for each other.

Full textAbstract:
Tsunamis are one of the most catastrophic natural events impacting coastal regions often generated by undersea earthquakes. Nevertheless, in enclosed basins, i.e., fjords, reservoirs and lakes, subaerial or submarine landslides can initiate devastating tsunamis with similar consequences. Although a subaerial or submarine landslide that impinges into a large water body can generate a tsunami, subaerial landslides are much more efficient tsunami generators than its counterpart. In this study we aim to integrate laboratory scale experiments of tsunami generation by subaerial landslide with numerical models. The work focuses on the numerical validation of two three-dimensional Navier-Stokes (3D-NS) models, FLOW-3D and our developed model TSUNAMI3D. The models are validated based on previous large scale laboratory experiments performed by a tsunami research team lead by Dr. Hermann Fritz, Georgia Institute of Technology. Three large scale landslide scenarios were selected from the set of laboratory experiments, namely, fjord like, headland and far field coastline. These scenarios showed that complex wave fields can be generated by subaerial landslides. The correct definition and evolution of the wave field are key to accurate modeling the ensuing tsunami and its effect in coastal regions. In this study, comparisons are performed between numerical results and laboratory experiments. Methodology and key parameters for soil rheology are defined for model validations. Results of the models are expected to be under the allowable errors indicated by the National Tsunami Hazard Mitigation Program (NTHMP), National Oceanic and Atmospheric Administration (NOAA) guidelines for validation of tsunami numerical models. The ultimate goal of this research is to obtain better tsunami calculation tools for real-world application of 3-D models for landslide tsunamis, which are necessary for the construction of inundation maps in the Gulf of Mexico and the Caribbean regions.

This thesis deals with the generational shift in women's attitudes towards the upbringing of their own children in the early 21st century. The aim of this thesis is to determine how today's generation of mothers reflects the upbringing of their parents, reflection of their own experience with upbringing and whether that leads to some inter- generational shift or change within the approach itself. Possible causes and influences of shifts and changes are discussed. To achieve this goal a qualitative analysis of semi-structured interviews with women - mothers was conducted. The research shows that in fact shifts in these approaches actually occur and that the main criterion is a reflection of one's own childhood in particular, reflection of one's parents and reflection of the current relationship with one's parents.
