Death Defied: James Joyce\u27s Naturalistic Evolution

Death, as a thematic and narrative motif, is of particular import to the Naturalistic literary approach. This is extremely evident in the work of James Joyce, on whom the Naturalist movement had a notable influence. Throughout his career Joyce utilized the subtext surrounding death in the father-son relationship to criticize Irish culture as it appears in his works. However, Joyce was not content to simply recreate a textbook interpretation of Naturalism. Joyce developed the core principles of the Naturalistic approach, starting with a basic and purely Naturalistic approach in his early writing; Joyce eventually managed to subvert and reinterpret the literary style that inspired his career. In Joyce\u27s earliest short story “The Sisters” (1914) he recounts the death of the defrocked priest Father Flynn from the perspective of a young boy to question the effects of the judgmental and unyielding nature of religion as Flynn is allowed to slip further into ill-health due to being excommunicated from the church. Joyce\u27s work becomes all the more complex in A Portrait of the Artist as a Young Man (1916) as he presents the subtleties of Simon and Stephen Dedalus\u27s relationship, and in the process criticizes paternalism as it leads to Simon\u27s failures and spiritual demise. Finally, in Ulysses (1922) he makes light of death itself as he presents the humorous and irreverent insight of Stephen\u27s alternative father figure Leopold Bloom as he attends the funeral of Paddy Dignam. In my paper I will examine death as it appears in these works spanning Joyce\u27s career. In the process, I observe the effect of Joyce\u27s treatment of death and paternalism, and how they, like his writing and interpretation of Naturalism, evolve throughout his career

Developing a decision support tool for the positioning and sizing of vortex flow controls in existing sewer systems

12th International Conference on Computing and Control for the Water Industry, CCWI2013This is the final version of the article. Available from Elsevier via the DOI in this record.This paper describes the development of a decision support tool for the positioning and sizing of vortex flow controls in existing sewer systems. The tool aims to prioritise the placement of vortex flow controls primarily within subcatchments with the greatest flood consequence rating and maximise the use of unused inpipe volumes during critical rainfall events. The decision support tool is intended for use in catchments where opportunities to implement SuDS and rainwater harvesting to defend against flooding are limited. The decision support tool is envisaged to identify potential strategies which could enhance flood resistance of sewer systems in a cost effective manner. © 2013 The Authors

The application of vernacular Australian environmental design principles in Glenn Murcutt’s architecture

Glenn Murcutt is recognised as one of the most influential architects of the last few decades. His design philosophy, environmental awareness and in-depth understanding of the Australian context and vernacular architecture, have made him one of the leaders of critical regionalism worldwide. His buildings not only provide shelter, but also offer comfort with lower environmental impacts through simple, yet creative design solutions. Although Murcutt’s architecture is well documented, limited evidence-based research has been undertaken to study his approach to design and how this has a direct influence on visual and thermal comfort in his buildings; this paper aims to fill this gap

The use of CFD coupled with physical testing to develop a new range of vortex flow controls with attributes approaching the ideal flow control device

This is the author accepted manuscript. The final version is available from the publisher via the DOI in this record.Vortex flow controls (VFC) are devices which are well suited for use in drainage systems, as they exhibit non-constant, non-linear discharge coefficients that can be tailored to approach that of a constant flow-rate device. Also, they have no mechanical components or power requirements and have a reduced risk of blockage compared with traditional flow controls. However, due to their complex bi-stable discharge behaviour and the influences of turbulence, the design and scaling of these devices, is not a trivial process. In this paper a VFC design methodology is presented that enables the VFC geometry to be determined and optimized to approach the ideal hydraulic behaviour, for a given discharge limit. This is achieved through the calibration of simplified, axi-symmetric vortex solutions of the Navier-Stokes relationships, by means of Computational Fluid Dynamic (CFD) analysis and experimental hydraulic assessment. © 2011 ASCE

Transformer Oil Passivation and Impact of Corrosive Sulphur

In recent years a significant volume of research has been undertaken in order to understand the recent failures in oil insulated power apparatus due to deposition of copper sulphide on the conductors and in the insulation paper. Dibenzyl Disulfide (DBDS) has been found to be the leading corrosive sulphur compound in the insulation oil [1]. The process of copper sulphide formation and the deposition in the paper is still being investigated, but a recently proposed method seems to be gaining some confidence [1]. This method suggests a two-step process; initially the DBDS and some oil soluble copper complexes are formed. Secondly the copper complexes are absorbed in the paper insulation, where they then decompose into copper sulphide [2]. The most commonly used mitigating technique for corrosive sulphur contaminated oil is passivation, normally using Irgamet 39 or 1, 2, 3-benzotriazole (BTA). The passivator is diluted into the oil to a concentration of around 100ppm, where it then reacts with the copper conductors to form a complex layer around the copper, preventing it from interacting with DBDS compounds and forming copper sulphide. This research project will investigate the electrical properties of HV transformers which have tested positive for corrosive sulphur, and the evolution of those properties as the asset degrades due to sulphur corrosion. Parallel to this the long term properties of transformers with passivated insulation oil will be analysed in order to understand the passivator stability and whether it is necessary to keep adding the passivator to sustain its performance. Condition monitoring techniques under investigation will include dielectric spectroscopy, frequency response analysis, recovery voltage method (aka interfacial polarisation) amongst others. Partial discharge techniques will not be investigated, as the voltage between the coil plates is low and therefore it will not contribute significantly to the overall insulation breakdown, in corrosive oil related faults [3]. The goal of this research is to establish key electrical properties in both passivated and non-passivated power transformers that demonstrate detectable changes as the equipment degrades due to the insulation oil being corrosive

Computational fluid dynamics of vortex flow controls at low flow rates

PublishedJournal ArticleA vortex flow control with differing outlet shapes is investigated computationally at low flow rates. The volume of fluid method was utilised to track the moving free surface. In order to achieve a smooth free surface, interface compression coupled with the inter-gamma compressive scheme was used. The turbulent evolution of the two-phase flow was modelled by solving the Reynolds-averaged Navier-Stokes equations with the k-ε model for turbulent quantities. Validation of the results was carried out by analysing the total head and discharge coefficient for the three outlet shapes at various flow rates and comparing these results with experimental data. Very good agreement with the experimental data was obtained

Deleting the IF1-like ζ subunit from Paracoccus denitrificans ATP synthase is not sufficient to activate ATP hydrolysis

In oxidative phosphorylation, ATP synthases interconvert two forms of free energy: they are driven by the proton motive force across an energy-transducing membrane to synthesize ATP and displace the ADP/ATP ratio from equilbrium. For thermodynamically-efficient energy conversion they must be reversible catalysts. However, in many species ATP synthases are unidirectional catalysts (their rates of ATP hydrolysis are negligible), and in others mechanisms have evolved to regulate or minimize hydrolysis. Unidirectional catalysis by Paracoccus denitrificans ATP synthase has been attributed to its unique ζ subunit, which is structurally analogous to the mammalian inhibitor protein IF1. Here, we used homologous recombination to delete the ζ subunit from the P. denitrificans genome and compared ATP synthesis and hydrolysis by the wild-type and knockout enzymes in inverted membrane vesicles and the F1-ATPase subcomplex. ATP synthesis was not affected by loss of the ζ subunit, and the rate of ATP hydrolysis increased by less than two fold, remaining negligible in comparison to the rates of the Escherichia coli and mammalian enzymes. Therefore, deleting the P. denitrificans ζ subunit is not sufficient to activate ATP hydrolysis. We close by considering our conclusions in the light of reversible catalysis and regulation in ATP synthase enzymes.This work was funded by the Medical Research Council (grant number U105663141 to J.H.)

Computational fluid dynamics as a tool for urban drainage system analysis: a review of applications and best practice

Computational Fluid Dynamics (CFD) can be applied to gain insights into most fluid processes and associated phenomena and so presents potential to add value in the analysis of urban drainage systems. This paper presents a review of CFD studies carried out in this field, with the objective of developing an appreciation of how and where it can be applied. Existing work has tended to focus around the analysis of four types of urban drainage structure, including Combined Sewer Overflows (CSOs), storage and attenuation systems, stormwater sediment interceptors and sewerage conveyance structures. Within the respective studies, the prediction of flowfields, particulate behaviour, water surface profiles and Residence Time Distributions (RTDs) are found to form the main focus, and as such, these are considered in most detail in the paper. It is concluded that CFD presents a number of opportunities in urban drainage system analysis, and that the scope of this opportunity will further develop as both computational hardware and software resources become more advanced

Use of q-values to Improve a Genetic Algorithm to Identify Robust Gene Signatures

Several approaches have been proposed for the analysis of DNA microarray datasets, focusing on the performance and robustness of the final feature subsets. The novelty of this paper arises in the use of q-values to pre-filter the features of a DNA microarray dataset identifying the most significant ones and including this information into a genetic algorithm for further feature selection. This method is applied to a lung cancer microarray dataset resulting in similar performance rates and greater robustness in terms of selected features (on average a 36.21% of robustness improvement) when compared to results of the standard algorithm
