Thermodynamics approach to the hydrogen diffusion and phase transformation in titanium particles

The hydrogen diffusion and phase transformation in a titanium particle were studied based on thermodynamic calculation. The mechanisms of hydrogen diffusion in different phases (alpha-Ti, beta-Ti and TiHx) were analyzed. A mobility database was developed for titanium– hydrogen system based on the experimental works on hydrogen diffusion coefficient reported in literature and the fundamental of diffusion. To implement the calculation, a commercial software package for the simulation of diffusion-controlled phase transformation was used. The hydrogen diffusion process, hydrogen distribution, phase transformation and phase growth rate during hydrogenization of a titanium particle at temperatures of 560 K, 800K and 1000K were discussed. The thermodynamics and kinetics analysis provided quantitative insight into the diffusion process and improved the understanding of diffusion mechanism and phase transformation.

Wandering Rocks : truth and purity in the Australian Irish diaspora

This thesis comprises a novel, Wandering Rocks, and a discursive component concerning the Australian Irish diaspora. Diaspora theory, loss of culture, rememory and silence (especially around accounts of Irish women), sentimental and creative forces perpetuating identity, and the importance of written works as artefacts imbued with ;milieu effects' are explored.

Flexible multibody approach in forward dynamic simulation of locomotive strains in human skeleton with flexible lower body bones

A method for bone strain estimation is examined in this article. The flexibility of a single bone in an otherwise rigid human skeleton model has been studied previously by various authors. However, in the previous studies, the effect of the flexibility of multiple bones on the musculoskeletal model behavior was ignored. This study describes a simulation method that can be used to estimate the bone strains at both tibias and femurs of a 65-year old Caucasian male subject. The verification of the method is performed by the comparison of the results with other studies available in literature. The results of the study show good correlation with the results of previous empirical studies. A damping effect of the flexible bones on the model is also studied in this paper.

Entrapping Christian and Muslim Arabs in racial cartoons in Australia : the other anti-semitism

Racial Cartoons are a powerful force disguised as entertainment operating to shape public opinion. During the 1980s, 1990s and after 9/11 in 2001, cartoons in the Australian press were particularly directed against Muslim and Christian Arabs without remorse or fear of redress or accountability. The offensive of such cartoons has essentially been directed on three fronts—oil, politics and religion. The drawback resulting from socio-cultural, historical and other differences are no doubt visible; but equally obvious is that anti-Semitism, which was directed against the Jews in the 1930s and 1940s, is today mostly directed against the public relations deprived, opinion silenced and undemocratically governed, ethnically diverse Arabs. It is argued in this paper that several forces were behind such distorted visual strategies adopted by the Australian press. Pre-judgement stemming from an inbuilt bias of the cartoonist, or highlighting characteristics which conform to the national interest are likely factors. The debate in Australia as to whether public images and attitudes of a minority “cause” or “determine” policy or whether policy itself changes attitudes is still resting with the jury.

A procedural, minimal input, natural terrain plug-in for Blender

This project uses methods of terrain representation, creation and realism described in literature. We find that using a combination of Fractional Brownian Motion and procedural formation of rivers via squig curves to form initial terrain, with hydraulic erosion for post processing, we have full control over the style of terrain: from jagged mountains to flat regions; and the phase of river from tightly rock controlled to flood plain regions.

Fatal women in renaissance tragedy, 1550-1650

Drawing upon the femme fatale of film noir, this thesis examines the presence of a fatal woman on the Renaissance stage. The thesis analyses the representation of emotionally and sexually independent women as fatally attractive to, yet ultimately destructive of, the men they entrap and seduce.

Subjective and objective point of view as metaphor in Mitko Panov’s With Raised Hands

What are we watching here? What is the nature of our discomfort? The point of view established in the opening of With Raised Hands – through the lens of a German camera recording the round-up of Jews in the Warsaw Ghetto – uncomfortably implicates us in this act of violence. The subsequent shifts in point of view are also supported by temporal shifts, both of which function at deeper, metaphorical levels to support the developing story.

Manipulating Islam and democracy in Iraq’s ‘Pluralised Authoritarianism’

With the realisation that the initial motives for the 2003 invasion of Iraq – Saddam’s alleged stockpile of Weapons of Mass Destruction (WMD) and his links to Al-Qaeda – were grievous intelligence errors the Bush administration, with varying degrees of success, were able to spin the war’s rasion d’etre and redefine the parameters of victory. A central tenet of this approach was to begin speaking about democracy as if it had always been one of the aims of the war itself. For the first few years, the effort to democratise Iraq appeared to gain some credible momentum: a complex array of political, religious and ethno-sectarian factions formed political parties and civil society movements; uncensored news was enthusiastically consumed across the nation; Iraqi citizens took to the streets to protest key government decisions; and millions of Iraqis voted in relatively free and fair national elections (Davis, 2004, 2007, Isakhan, 2008, 2011b). Central to each of these developments were various Iraqi religious establishments – but especially those of the Shia Arab population of Iraq – who saw no distinction between their Islamic faith and the notion of democracy. Not surprisingly, a body of literature has emerged which has been very optimistic about Iraq’s engagement with both ‘Islam’ and ‘democracy’ in the post-Baathist period, while acknowledging the challenges it faces in creating a stable, egalitarian and democratic society (Al-Musawi, 2006, Cole, 2006, Davis, 2005, Dawisha, 2009, Isakhan, 2011a, Stansfield, 2007).

However, there have been virtually no studies which have sought to question this optimism in the light of more recent events. Addressing this lacuna, this paper documents the last few years (2006- 2011) which have seen many elements within the Iraqi political elite – most notably the Maliki government and his State of Law Coalition (SLC) – demonstrate what has been referred to in literature on other Arab states alternatively as ‘liberalised autocracy’ (Brumberg, 2002), ‘semi-authoritarianism’ (Ottaway, 2003) or ‘pluralised authoritarianism’ (Posusney and Angrist, 2005). That is to say, that these states consolidate their incumbency while putting in place measures that can be considered more or less liberal. To do this, the regime actually utilises (and controls) nominally democratic mechanisms such as elections, media freedoms, political opposition and civil society as part of their strategy to retain power. Of particular interest here are the ways in which the Maliki government – and Shia Arab Iraqi political factions more broadly – have manipulated both ‘Islam’ and ‘democracy’ towards such ‘pluralised authoritarianism’.

Landscapes in transition : local perceptions of indigenous and European settlement changes along the Victorian coast

Around the world coastal areas are witnessing dramatic changes due to the consequences of the growth of human settlements. Rapid urban expansion in coastal settlements due to ‘life style migration’ impacts negatively on environmental coastal amenities that are the driving factor behind the attraction of these areas. The Victorian Coast in Australia is under stress, with the growth pattern of coastal settlements in a sprawling linear fashion resulting in devastating effects on the natural coastal environment, biodiversity and the loss of cultural heritage. The Victorian coast is rich in history, and the coastal towns are often described in literature as places with ‘sense of place’, or referred to as place character. This place character has been formed over many years with the interaction between social histories and natural environments woven together across time. This paper reviews the transition of the landscapes along the Great Ocean Road coastal region, and ask the question how can a potential Generative Plan be developed to establish a process to keep the place character of coastal towns. The proposed plan considers the interrelationships of nature and people as fundamental to forming place character, from the time of Indigenous habitation before European settlement, to the current day of rapid increased developments scattered along this coast.

"Spontaneous overflow of powerful feelings" : romantic imagery in Mary Shelley's Frankstein

Romantic English literature – written at a time when prose fiction was predominantly a medium for sheer entertainment – is rooted in poetry. One or two novelists may exceptionally be granted the adjective “Romantic”, but Mary Shelley is not ranked among them. For centuries, her work has been restricted to that section in handbooks reserved for exotic Gothic literature. This thesis argues that literary criticism has failed to recognize Frankenstein’s obvious relation with the movement. The argument will be fostered by a brief look at such handbooks, and developed through the analysis of the imagery of the novel, so as to trace the Romantic elements there contained. The analysis relies mainly on the frame developed by Northrop Frye concerning the nature and function of imagery in literature. The concept of intertextuality will also be useful as a tool to account for the insertion of images in the novel, and for the novel’s insertion within the Romantic context. The work is divided into three parts. The first contextualizes the main issues set forth by Frankenstein, establishing connections with the life of the author and with the Romantic movement. The second exposes the theoretical basis on which the thesis is grounded. The last presents my reading of the novel’s web of images. In the end, I hope to validate the thesis proposed, that Frankenstein embodies the aesthetic and philosophical assessments of the English Romantic agenda, and therefore deserves to be situated in its due place in the English Literary canon as the legitimate representative of Romanticism in prose form.

Determination of lipophilic and hydrophilic antioxidants in Solanum Lycopersicum L. tomato from Gordal variety by LL-USAE combined with UHPLC-PDA/FLR

Tomato (Lycopersicon esculentum L.) is one of the main constituents of the Mediterranean diet. Its consumption has been proposed to reduce the risk of cardiovascular diseases and certain types of cancer. It is therefore one of the most popular and extensively consumed vegetable crop worldwide. To gain insights on the potential of Lycopersicon esculentum L. as bioactive food, two analytical methodologies were developed to determine the levels of the lipophilic -tocopherol, α-tocopherol, β-carotene, lycopene; and hydrophilic antioxidants ascorbic acid. The quantification of total carotenoids (β-carotene and lycopene) was assessed through a liquid–liquid ultrasound assisted extraction (LL-USAE) in combination with ultraviolet-visible spectroscopy (UV-Vis), according to method of mean, for total carotenoids (λmáx = 450 nm. The ultra-high performance liquid chromatographic using both photodiode array and fluorescence detection (UHPLC-PDA/FLR), allows the identification and quantification of the target lipophilic and hydrophilic antioxidants. This methodology UHPLC-PDA/FLR is fast, simple and revealed a high sensitivity for the compounds under study. The limits of detection (LODs) and quantification (LOQs) obtained were much lower (about 10 times) than the reported in literature. The method LL-USAE/UV-Vis was validated and applied to different tomato foodstuffs. The results reveal a small increase of carotenoids content during maturation, reaching the maximum level when ripe. These results complement those obtained by the ORAC and TBARS assays that show an increase of antioxidant capacity during maturation. The LODs ans LOQs obtained were also about 10 times lower than reported in literature. The carotenoid content was also evaluated by LL-USAE/UV-Vis in different tomatoes varieties. Regional variety present the high carotenoid level, followed by campari and gordal, and at last grape. This methodology was also applied to different processed food samples containing tomatoes derivatives. Highest carotenoids content were obtained in concentrated tomato foodstuffs.

Estimating mortality in laying hens as the environmental temperature increases

Layer mortality due to heat stress is an important economic loss for the producer. The aim of this study was to determine the mortality pattern of layers reared in the region of Bastos, SP, Brazil, according to external environment and bird age. Data mining technique were used based on monthly mortality records of hens in production, 135 poultry houses, from January 2004 to August 2008. The external environment was characterized according maximum and minimum temperatures, obtained monthly at the meteorological station CATI in the city of Tupa, SP, Brazil. Mortality was classified as normal (<= 1.2%) or high (> 1.2%), considering the mortality limits mentioned in literature. Data mining technique produced a decision tree with nine levels and 23 leaves, with 62.6% of overall accuracy. The hit rate for the High class was 64.1% and 59.9% for Normal class. The decision tree allowed finding a pattern in the mortality data, generating a model for estimating mortality based on the thermal environment and bird age.
