Cloth & memory

This book was published to accompany an exhibition of the same name at Salts Mills, Saltaire, Yorkshire, UK, in summer 2012, conceived and directed by Lesley Millar MBE, Professor of Textile Culture at the University for the Creative Arts. The exhibition and accompanying publication includes work by the artists Beverley Ayling-Smith, Carol Quarini, and Bob White. All visited Salts Mills and Saltaire and have created their work as a response to the history of the place: the memory of cloth and the making of cloth that has seeped into the fabric of the building. This exhibition is the first of two; Cloth and Memory 2 taking place in 2013

Research students exhibition catalogue 2013

This exhibition catalogue showcases the work of current UCA research students at various stages of their research journey. The theme of the exhibition and the one day conference is time - place - space and through their practice the research students examine these concepts and realities

Noninvasive Monitoring by Ultrasound of Liquid Foodstuff to Ice Slurry Transitions Within Steel Ducts and Pipes

Ultrasound was assessed as a noninvasive method of detecting dynamic transitions occurring as a scouring high ice fraction ice slurry forces liquid food products through process lines. The attenuation of ultrasound waves passing through a test section was measured within a time window that captured waves with arrival time's characteristic of a direct path through the tubing and its contents. A recording transducer measuring the attenuated signal provided an output in volts, corresponding to the extent of attenuation. Water as a comparable substitute for a liquid food product gave typical values of 2.32 ± 0.07 V for mean amplitude of these waves. The passage of ice slurry reduced this value to 0.75 ± 0.03 V which represented a highly significant (P < 0.001) reduction in transmission. Tomato soup under similar circumstances gave values of 1.93 ± 0.09 V reduced to 0.64 ± 0.02 V when ice slurry flowed between the transducers. Dynamic transitions involving yoghurt and yoghurt mixtures were also detectable except when the yoghurt and the ice slurry shared similar degrees of signal attenuation. Pipe geometry was typically found to introduce systematic changes to recorded values but these did not detract from the basic finding that significant differences were always found between flowing food products and ice slurry, except in the case of pure yoghurt in a large channel. Noninvasive monitoring of dynamic product to ice slurry transitions in food grade steel pipes by ultrasound is readily achievable and could become a method of choice for product recovery systems

Research students exhibition catalogue 2011

The catalogue demonstrates the scope and vibrancy of current inquiries and pays tribute to the creative capacity and investment of UCA research students. It brings together contributions from students who are at different stages in their research ad/venture. Their explorations are connected by the centrality of contemporary material practices as focal point for the reconsideration of societal values, cultural symbols and rituals and their meaning, and the trans/formation of individual, collective and national identities The media and formats employed range from cloth, jewellery and ceramics to analogue film, the human voice and the representation of dress and fashionin virtual environments. Thematic interests span from explorations at the interface of art and medical science to an investigation of the role of art in contested spaces, or the role of metonymy in ‘how the arts think’ And whilst the projects are motivated by personal curiosity and passion, their outcomes transcend the boundaries of individual practice and offer new insights, under-standing and applications for the benefit of wider society.

The domestic veil: exploring the net curtain through the uncanny and the gothic

This research aims to develop original creative practice, using the net curtain to reconsider the domestic, through the lenses of the uncanny and the gothic. The net curtain, hanging in the liminal space between the public and the private, is used to embody Freud’s 1919 definition of the uncanny, as the point of slippage between the homely and the unhomely. Also central to this research are ideas about the gothic and gendered domesticity, in particular, the gothic fiction of the mid-nineteenth century that critiqued the idea of 'separate spheres'

The anomalous pressure drop behaviour of ice slurries flowing through constrictions

The effective ‘viscosity’ for ice slurry containing more than say 30 to 40% ice fraction is many orders of magnitude higher than that for water. However, this work suggests that such slurries, when flowing through constrictions, can incur lower pressure drops than water flowing at the same rate through the same topology. This paradoxical finding is explored, studied and reported in this paper. It is thought that this reduction in pressure drop is the result of ice particles inhibiting the onset of turbulence in the ice slurry. Other researchers have previously observed this phenomenon in slurries of lower ice fractions. It is also suggested that the relatively low pressure drops observed for high ice fractions may be due to complex heat transfer and phase change phenomena, which are likely to occur at the ice-wall interface

Investigation into the transportation and melting of thick ice slurries in pipes

This paper presents the results of experiments and modelling carried out on ice slurries flowing in uninsulated steel pipes with a nominal diameter of 50 mm. The slurries used were formed from 4.75% NaCl aqueous solution and had ice mass fractions in the range 18–42%, with a view to the use of thick ice slurry ‘pigs’ as a pipeline clearing technique. Of particular interest was the distance over which such slurries can survive as plug-like entities, before melting reduces them to ineffective thin two-phase suspensions. The experiments showed that for small volumes of slurry, survivability is directly proportional to the quantity of slurry used, but that increasing the ice fraction has a more marked effect. A simple one-dimensional numerical model that accounts for transportation, heat transfer and melting was developed that produces reasonable predictions
