Mimicry And Mimesis: Matrix Insect, Madeleine Kelly Jun 2016

Mimicry And Mimesis: Matrix Insect, Madeleine Kelly

Animal Studies Journal

Paintings and insects might seem like odd companions. In this paper I describe how a series of paintings I made depicting insects creates associations between mimesis and mimicry in order to flag a sort of protective self-referentiality – one where painting resists its proverbial ‘end’ and insects are presented as vital new orders. Drawing upon art historical references, such as Surrealism and the modernist grid, I argue that playing on these references and the compositional effects of camouflage enlivens our regard for the sensuous worlds of both insects and painting. I conclude by exploring how paintings of insects are powerful …


Do Insects Feel Pain?, Helen Tiffin Jun 2016

Do Insects Feel Pain?, Helen Tiffin

Animal Studies Journal

This paper briefly considers the broad social and scientific background to research into the possibility of insects experiencing pain sensations analogous to our own. There has been increasing use of insects in pain experiments generally, as ethical constraints on the use of other animals increased through the last century. The ways in which scientists have tackled the question of insect pain, particularly in trying to distinguish between nociception and pain are then selectively summarised. These include opioid, hormonal, evolutionary, neurophysiological and behavioural approaches, as well as experiments designed to elucidate the difficult area of insect consciousness, from the 1980s to …


[Review] Robert Cribb, Helen Gilbert And Helen Tiffen, Wild Man From Borneo: A Cultural History Of The Orangutan. Honolulu: University Of Hawai’I Press, 2014, Matthew Chrulew Jun 2016

[Review] Robert Cribb, Helen Gilbert And Helen Tiffen, Wild Man From Borneo: A Cultural History Of The Orangutan. Honolulu: University Of Hawai’I Press, 2014, Matthew Chrulew

Animal Studies Journal

Wild Man from Borneo is a studious and wide-ranging cultural history of the orangutan and an indispensable resource for anyone working on this species or great apes in general. Orangutan stories and encounters have always captivated, from the tales of the Dayak and Batak peoples from Borneo and Indonesia, to the first rumours of early European travellers, and later observations and dissections. The orangutan’s uncanny similarity to humans, both in form and behaviour, made it central to a nineteenth-century debate about the uniqueness of humanity, in a time when few had been seen and Europeans were unsure just what sort …


[Review] David Wilson, The Welfare Of Performing Animals: A Historical Perspective. Berlin: Springer, 2015, Peta Tait Jun 2016

[Review] David Wilson, The Welfare Of Performing Animals: A Historical Perspective. Berlin: Springer, 2015, Peta Tait

Animal Studies Journal

This book makes a valuable contribution to animal studies. It investigates the social and political processes concerned with the welfare of performing animals in Britain from the nineteenth century into the twentieth century. Although this area requires specialised inquiry, as David Wilson points out, animal performance is usually generalised about within pro-animal scholarship. Drawing on highly detailed research, this book provides a comprehensive account of the individuals and organisations that campaigned against animal performance and its cruelties and, in turn, those who campaigned for its continuation. It presents the human stories behind the movement against animal performance; descriptions of the …


Toothsome Termites And Grilled Grasshoppers: A Cultural History Of Invertebrate Gastronomy, Deirdre P. Coleman Jun 2016

Toothsome Termites And Grilled Grasshoppers: A Cultural History Of Invertebrate Gastronomy, Deirdre P. Coleman

Animal Studies Journal

This article examines the recent turn to entomophagy (insect eating) as a new source of nutrition in a world confronted by increasing population, degraded soils, and food insecurity. Although many regard entomophagy with disgust, there is a case to be made that many insects are much more nutritious, as well as greener and cleaner¹, than many of the foods we regularly eat without thinking. Also, there is nothing new about insect eating or the belief in entomophagy as a sustainable and sensible practice. There is a long cultural history in countries such as Africa and Australia, for instance.


Thirteen Figurings: Reflections On Termites, From Below, Perdita Phillips Jun 2016

Thirteen Figurings: Reflections On Termites, From Below, Perdita Phillips

Animal Studies Journal

This image essay is a creative reflection back upon The Encyclopaedia Isoptera: An encyclopaedia of the arts, sciences, literature and general information about termites, which was mostly written by the artist between 1997 and 1998, and forward to what termite art might undo today. Without access to living termites and, predating multispecies ethnographies, the Encyclopaedia Isoptera was an investigation into the limits of knowledge around termites. Looking back, it can be seen that certain strategies in the Encyclopaedia, such as looking at superseded or alternative knowledge, was a way of interrogating the boundaries of the sensible/insensible, and parallels more recent …


Humans, Insects And Their Interaction: A Multi-Faceted Analysis, Raynald H. Lemelin, Rick W. Harper, Jason Dampier, Robert Bowles, Debbie Balika Jun 2016

Humans, Insects And Their Interaction: A Multi-Faceted Analysis, Raynald H. Lemelin, Rick W. Harper, Jason Dampier, Robert Bowles, Debbie Balika

Animal Studies Journal

By administering Personal Meaning of Insects Maps (PMIM) to participants from eastern Canada and northeastern United States, we examine how people’s perceptions of insects are often determined by childhood encounters, corporeal cues, and influenced by environmental preference during recreational activities, often resulting in inconsistencies, inaccuracies, and bias. While the purpose of this study was to acquire a greater understanding of these entanglements through visual maps, the goal of this paper is to disentangle these morasses by highlighting the various positive, negative, dialectic, and ambivalent aspects of how insects are perceived.


Through The Eyes Of A Bee: Seeing The World As A Whole, Adrian G. Dyer, Scarlett R. Howard, Jair E. Garcia Jun 2016

Through The Eyes Of A Bee: Seeing The World As A Whole, Adrian G. Dyer, Scarlett R. Howard, Jair E. Garcia

Animal Studies Journal

Honeybees are an important model species for understanding animal vision as free-flying individuals can be easily trained by researchers to collect nutrition from novel visual stimuli and thus learn visual tasks. A leading question in animal vision is whether it is possible to perceive all information within a scene, or if only elemental cues are perceived driven by the visual system and supporting neural mechanisms. In human vision we often process the global content of a scene, and prefer such information to local elemental features. Here we discuss recent evidence from studies on honeybees which demonstrate a preference for global …

A Sustainable Campus: The Sydney Declaration On Interspecies Sustainability, Fiona Probyn-Rapsey, Sue Donaldson, George Ioannides, Tess Lea, Kate Marsh, Astrida Neimanis, Annie Potts, Nik Taylor, Richard Twine, Dinesh Wadiwel, Stuart White

Animal Studies Journal

Under the remit of an expanded definition of sustainability – one that acknowledges animal agriculture as a key carbon intensive industry, and one that includes interspecies ethics as an integral part of social justice – institutions such as Universities can and should play a role in supporting a wider agenda for sustainable food practices on campus. By drawing out clear connections between sustainability objectives on campus and the shift away from animal based products, the objective of this article is to advocate for a more consistent understanding and implementation of sustainability measures as championed by university campuses at large. We …


The Intersectional Influences Of Prince: A Human-Animal Tribute, Annie K. Potts Jun 2016

The Intersectional Influences Of Prince: A Human-Animal Tribute, Annie K. Potts

Animal Studies Journal

Prince Rogers Nelson (1958-2016) was best known for his joyful funk music and electrifying stage performances that transgressed normative representations of gender, sexuality, race, spirituality, identity and taste. He was also a compassionate person who held deep convictions about freedom and the right of all species to enjoy lives without fear and suffering. This essay discusses Prince’s intersectional influences – the various ways his virtuosity over the past 38 years disrupted binaries, challenged assumptions and stereotypes, advocated for social justice, and combatted speciesism in its many forms. Embedded within the essay are seven personal tributes written by fans of Prince …


[Review] Ann C. Colley, Wild Animal Skins In Victorian Britain. Farnham: Ashgate, 2014, John Simons Jun 2016

[Review] Ann C. Colley, Wild Animal Skins In Victorian Britain. Farnham: Ashgate, 2014, John Simons

Animal Studies Journal

You should never judge a book by its cover but, of course, that’s exactly what the Victorians did when they looked at animals—or so Professor Ann Colley claims, and with some justification. This book is a contribution to the growing list of valuable and entertaining studies of the collection and exhibition of wild animals in Victorian Britain and beyond, and it is highly recommended to anyone researching the field. I was looking forward to reading this as although there has been a fair bit of work on zoos and menageries and, especially recently, on taxidermy, the habit of collecting skins …


Provocations From The Field : The Place Of Bees, Michael R. Griffiths Jun 2016

Provocations From The Field : The Place Of Bees, Michael R. Griffiths

Animal Studies Journal

What would it mean to permit lack to become a productive place? What, indeed, would it mean to think place – so often feminized in the carnophallogocentric order – as active? Lack, in these terms, could be constitutive rather than a mere marker of absence. I propose that the place of bees in the symbolics of species could yield answers to these and related questions. Insects are often understood and conceived as communicators – through pheromones for instance. But in the very gesture that recognizes their communication, one finds the refusal of consciousness behind this communicative apparatus. If bees are …


Mechanical Fatigue Performance Of Pcl-Chondroprogenitor Constructs After Cell Culture Under Bioreactor Mechanical Stimulus, J A. Panadero, Vitor Sencadas, Sonia C.M. Silva, Clarisse Ribeiro, Vítor Correia, F M. Gama, J L. Gomez Ribelles, Senentxu Lanceros-Méndez Jan 2016

Mechanical Fatigue Performance Of Pcl-Chondroprogenitor Constructs After Cell Culture Under Bioreactor Mechanical Stimulus, J A. Panadero, Vitor Sencadas, Sonia C.M. Silva, Clarisse Ribeiro, Vítor Correia, F M. Gama, J L. Gomez Ribelles, Senentxu Lanceros-Méndez

Faculty of Engineering and Information Sciences - Papers: Part A

In tissue engineering of cartilage, polymeric scaffolds are implanted in the damaged tissue and subjected to repeated compression loading cycles. The possibility of failure due to mechanical fatigue has not been properly addressed in these scaffolds. Nevertheless, the macroporous scaffold is susceptible to failure after repeated loading- unloading cycles. This is related to inherent discontinuities in the material due to the micropore structure of the macropore walls that act as stress concentration points. In this work, chondrogenic precursor cells have been seeded in poly-e-caprolactone (PCL) scaffolds with fibrin and some were submitted to free swelling culture and others to cyclic …


Effect Of Different Frp Wrapping Arrangements On The Confinement Mechanism, Thong M. Pham, Jim Youssed, Muhammad N. S Hadi, Tung M. Tran Jan 2016

Effect Of Different Frp Wrapping Arrangements On The Confinement Mechanism, Thong M. Pham, Jim Youssed, Muhammad N. S Hadi, Tung M. Tran

Faculty of Engineering and Information Sciences - Papers: Part A

This study aims to investigate the structural behavior and failure modes of fiber-reinforced-polymer (FRP) confined concrete wrapped with different FRP arrangements. A total of twenty four specimens were cast and tested, with three of these specimens acting as reference specimens and the remaining specimens wrapped with different types of FRP (CFRP and GFRP) by different wrapping arrangements. They include fully wrapped, partially wrapped and non-uniformly wrapped concrete cylinders. The nonuniformly wrapped concrete cylinders provided higher compressive strengths and strain for FRP-confined concrete, in comparison with conventional fully wrapping arrangements. The effect of confinement level on the effectiveness of FRP confinement …

3d Face Recognition Using Anthropometric And Curvelet Features Fusion, Dan Song, Jing Luo, Chunyuan Zi, Huixin Tian Jan 2016

3d Face Recognition Using Anthropometric And Curvelet Features Fusion, Dan Song, Jing Luo, Chunyuan Zi, Huixin Tian

Faculty of Engineering and Information Sciences - Papers: Part A

Curvelet transform can describe the signal by multiple scales, and multiple directions. In order to improve the performance of 3D face recognition algorithm, we proposed an Anthropometric and Curvelet features fusion-based algorithm for 3D face recognition (Anthropometric Curvelet Fusion Face Recognition, ACFFR). First, the eyes, nose, and mouth feature regions are extracted by the Anthropometric characteristics and curvature features of the human face. Second, Curvelet energy features of the facial feature regions at different scales and different directions are extracted by Curvelet transform. At last, Euclidean distance is used as the similarity between template and objectives. To verify the performance, …


Af-Embeddability Of 2-Graph Algebras And Quasidiagonality Of K-Graph Algebras, Lisa Orloff Clark, Astrid An Huef, Aidan Sims Jan 2016

Af-Embeddability Of 2-Graph Algebras And Quasidiagonality Of K-Graph Algebras, Lisa Orloff Clark, Astrid An Huef, Aidan Sims

Faculty of Engineering and Information Sciences - Papers: Part A

We characterise quasidiagonality of the C*-algebra of a cofinal k-graph in terms of an algebraic condition involving the coordinate matrices of the graph. This result covers all simple k-graph C*-algebras. In the special case of cofinal 2-graphs we further prove that AF-embeddability, quasidiagonality and stable finiteness of the 2-graph algebra are all equivalent.


Analysis Of Bacterial Diversity In Two Oil Blocks From Two Low-Permeability Reservoirs With High Salinities, Meng Xiao, Shan Shan Sun, Zhong Zhi Zhang, Junming Wang, Long Wei Qiu, Hua Yang Sun, Zhaozheng Song, Beiyu Zhang, De Li Gao, Guangqing Zhang, Wei Min Wu Jan 2016

Analysis Of Bacterial Diversity In Two Oil Blocks From Two Low-Permeability Reservoirs With High Salinities, Meng Xiao, Shan Shan Sun, Zhong Zhi Zhang, Junming Wang, Long Wei Qiu, Hua Yang Sun, Zhaozheng Song, Beiyu Zhang, De Li Gao, Guangqing Zhang, Wei Min Wu

Faculty of Engineering and Information Sciences - Papers: Part A

The community diversities of two oil reservoirs with low permeability of 1.81 x 10 '3 and 2.29 x 10 '3 1/4m 2 in Changqing, China, were investigated using a high throughput sequencing technique to analyze the influence of biostimulation with a nutrient activator on the bacterial communities. These two blocks differed significantly in salinity (average 17,500 vs 40,900 mg/L). A core simulation test was used to evaluate the effectiveness of indigenous microbial-enhanced oil recovery (MEOR). The results indicated that in the two high salinity oil reservoirs, one reservoir having relatively lower salinity level and a narrow salinity range had higher …


Critical Assessment 20: On Carbon Excess In Bainitic Ferrite, Elena V. Pereloma Jan 2016

Critical Assessment 20: On Carbon Excess In Bainitic Ferrite, Elena V. Pereloma

Faculty of Engineering and Information Sciences - Papers: Part A

For several decades, the question of carbon supersaturation in bainitic ferrite has attracted the attention of physical metallurgists. Originally, this was associated with excess carbon due to the displacive nature ofphase transformation and its subsequent trappingatdefects inbainitic ferrite. The development of advanced experimental techniques, such as atom probe tomography and in situ synchrotron and neutron X-ray diffraction, has provided new insights into carbon distribution within bainitic ferrite. Possible explanations for carbon excess in solid solution are discussed, and the pathways for the future advancement of this research question are suggested.

Breakaway Oxidation Behaviour Of Ferritic Stainless Steels At 1150 °C In Humid Air, Xiawei Cheng, Zhengyi Jiang, Brian J. Monaghan, Dongbin Wei, Raymond Longbottom, Jingwei Zhao, Jianguo Peng, Ming Luo, Li Ma, Suzhen Luo, Laizhu Jiang

Faculty of Engineering and Information Sciences - Papers: Part A

The breakaway oxidation behaviour of ferritic stainless steels 430, 443 and 445 has been investigatedat 1150◦C in humid air. The oxidation kinetics exhibited significant differences among the three ferriticstainless steels. A uniform and steady growing oxide scale was developed on the 430 steel with an evensteel/oxide interface. Local breakdown of the initially protective oxide scale occurred and oxide noduleswere developed on the 443 and 445 stainless steels, resulting in irregular and rough steel/oxide inter-faces. The breakaway oxidation behaviour was significantly influenced by the microstructure and thecomposition of the oxide scale. The Mn-Cr spinel oxide formed on top of the Cr2O3scale …


One-Round Strong Oblivious Signature-Based Envelope, Rongmao Chen, Yi Mu, Willy Susilo, Guomin Yang, Fuchun Guo, Mingwu Zhang Jan 2016

One-Round Strong Oblivious Signature-Based Envelope, Rongmao Chen, Yi Mu, Willy Susilo, Guomin Yang, Fuchun Guo, Mingwu Zhang

Faculty of Engineering and Information Sciences - Papers: Part A

Oblivious Signature-Based Envelope (OSBE) has been widely employed for anonymity-orient and privacy-preserving applications. The conventional OSBE execution relies on a secure communication channel to protect against eavesdroppers. In TCC 2012, Blazy, Pointcheval and Vergnaud proposed a framework of OSBE (BPV-OSBE) without requiring any secure channel by clarifying and enhancing the OSBE security notions. They showed how to generically build an OSBE scheme satisfying the new strong security in the standard model with a common-reference string. Their framework requires 2-round interactions and relies on the smooth projective hash function (SPHF) over special languages, i.e., languages from encryption of signatures. In this …

Items identified included types of information systems, compliance with accreditation standards, and indicators of failure to meet …


Biomethane Potential Evaluation Of Co-Digestion Of Sewage Sludge And Organic Wastes, Richard Wickham, Brendan Galway, Heriberto A. Bustamante, Long D. Nghiem Jan 2016

Biomethane Potential Evaluation Of Co-Digestion Of Sewage Sludge And Organic Wastes, Richard Wickham, Brendan Galway, Heriberto A. Bustamante, Long D. Nghiem

Faculty of Engineering and Information Sciences - Papers: Part A

Co-digestion of organic rich wastes and wastewater sludge to enhance biogas production has become an attractive economic possibility for water utilities. The suitability of the organic rich waste depends on its ability to produce biogas as well as its influence on the overall anaerobic digestion process. Biomethane potential evaluation was conducted to screen seven organic wastes and dehydrated algae. All co-substrates increased the bio-methane yield by three to six times compared with conventional anaerobic digestion of sewage sludge. Maximum co-digestion ratios were identifiable for most solid co-substrates including algae (6% wt/wt), undiluted food waste (5% wt/wt), bakery waste (5% wt/wt), …


Membrane Distillation And Membrane Electrolysis Of Coal Seam Gas Reverse Osmosis Brine For Clean Water Extraction And Naoh Production, Hung Duong, Mikel C. Duke, Stephen Gray, Bart Nelemans, Long D. Nghiem Jan 2016

Membrane Distillation And Membrane Electrolysis Of Coal Seam Gas Reverse Osmosis Brine For Clean Water Extraction And Naoh Production, Hung Duong, Mikel C. Duke, Stephen Gray, Bart Nelemans, Long D. Nghiem

Faculty of Engineering and Information Sciences - Papers: Part A

Membrane distillation (MD) and membrane electrolysis (ME) were evaluated for simultaneous fresh water extraction and NaOH production from a mixture of NaCl and NaHCO3 to simulate the composition of coal seam gas (CSG) reverse osmosis (RO) brine. Experimental results demonstrate the potential of MD for producing fresh water and simultaneously concentrating CSG RO brine prior to the ME process. MD water flux was slightly reduced by the increased feed salinity and the decomposition of bicarbonate to CO2 during the concentration of CSG RO brine. MD operation of CSG RO brine at a concentration factor of 10 (90% water recovery) was …

Faculty of Engineering and Information Sciences - Papers: Part A

Coalwash (CW) is granular waste by-product that results from the operation of the local coal mining industry. The reuse and recycling of this material in earthwork construction project as landfill option, is attractive from both economic and environmental perspectives. This paper presents an experimental study on compacted CW material prepared at different relative compaction levels. First the basic materials index properties are described and the stress-dilatancy behaviour is examined through a series of drained triaxial compression tests. The experimental data suggests that the different relative compaction levels exhibit different stress strain behaviour but show some degree of similarity in terms …


The Swelling Behaviour Of Lignosulfonate-Treated Expansive Soil, Dennis Pere Alazigha, Buddhima Indraratna, J S. Vinod, Lambert Emeka Ezeajugh Jan 2016

The Swelling Behaviour Of Lignosulfonate-Treated Expansive Soil, Dennis Pere Alazigha, Buddhima Indraratna, J S. Vinod, Lambert Emeka Ezeajugh

Faculty of Engineering and Information Sciences - Papers: Part A

This paper presents results regarding the potential of lignosulfonate (LS) to control the swelling of expansive soil. One-dimensional swell tests were performed on untreated and LS-treated remoulded samples of Australian expansive soil from the state of Queensland. The test results indicated that LS has significant influence on the swelling behaviour of this expansive soil. The results were compared with those of identical cement-treated soil samples, and it was found that LS could be a economical and environmentally friendly alternative to traditional alkaline additives. In addition, the behaviour of LS-treated specimens during repeated freezing and thawing cycles was measured. The results …

Phosphorus And Water Recovery By A Novel Osmotic Membrane Bioreactor - Reverse Osmosis System, Wenhai Luo, Faisal I. Hai, William E. Price, Wenshan Guo, Hao H. Ngo, Kazuo Yamamoto, Long D. Nghiem

Faculty of Engineering and Information Sciences - Papers: Part A

An osmotic membrane bioreactor-reverse osmosis (OMBR-RO) hybrid system integrated with periodic microfiltration (MF) extraction was evaluated for simultaneous phosphorus and clean water recovery from raw sewage. In this hybrid system, the forward osmosis membrane effectively retained inorganic salts and phosphate in the bioreactor, while the MF membrane periodically bled them out for phosphorus recovery with pH adjustment. The RO process was used for draw solute recovery and clean water production. Results show that phosphorus recuperation from the MF permeate was most effective when the solution pH was adjusted to 10, whereby the recovered precipitate contained 15-20% (wt/wt) of phosphorus. Periodic …


A Magnetically Actuated Drug Delivery System For Robotic Endoscopic Capsules, Fredy Munoz, Gursel Alici, Weihua Li Jan 2016

A Magnetically Actuated Drug Delivery System For Robotic Endoscopic Capsules, Fredy Munoz, Gursel Alici, Weihua Li

Faculty of Engineering and Information Sciences - Papers: Part A

There is an increasing need to incorporate an actively controlled drug delivery system (DDS) into the next generation of capsule endoscopy in order to treat diseases in the gastrointestinal tract in a noninvasive way. Despite a number of attempts to magnetically actuate drug delivery mechanisms embedded in endoscopic capsules, longer operating distances and further miniaturization of on-board components are still drawbacks of such systems. In this paper, we propose an innovative magnetic system that consists of an array of magnets, which activates a DDS, based on an overly miniaturized slider-crank mechanism. We use analytical models to compare the magnetic fields …

Faculty of Engineering and Information Sciences - Papers: Part A

Using nonlinear finite element method, a thermo-mechanical coupled simulation model for the formation mechanism of the laminated crack defect has been established in the upsetting of heavy disk-shaped forgings. Through numerical simulation, the distributions of stress, equivalent strain and strain rate were analysed. Meanwhile the distribution diagram of stress state evolution was obtained, and the uncoordinated deformation, under tri-lateral compression, is determined as the main reason leading to laminated crack defect. To reveal the characteristics of the uncoordinated deformation, the variations of each variable and its gradient in numerical simulation were presented, and a combined prediction model of laminated crack …
