Designing 21st Century Standard Ware: The Cultural Heritage of Leach and the Potential Applications of Digital Technologies
No full textThis practice-based research investigates the potential applications of digital manufacturing technologies in the design and production of hand-made tableware at the Leach Pottery. The methodology for the research establishes an approach grounded in my previous experience as a maker that is informed by an open, experimental, emergent, and responsive framework based on Naturalistic Inquiry.
A critical contextual review describes the cultural heritage of Leach which, for the purposes of the research, is developed through the Leach Pottery as a significant site, the historical production of the iconic Leach Standard Ware and the contemporary production of Leach Tableware. This is followed by an examination of Potter’s Tools in the Leach production environment, and a review of makers’ digital ceramic practice.
The contextual review is followed by an explication of ‘standards’ presented through visual lineages of Standard Ware and Leach Tableware to define ‘standard’ at a design (macro) level, followed by an examination of how ‘standard’ operates at a making (micro level) level. This chapter presents new knowledge in relation to defining the visual field of Leach Pottery tableware production and its standards of design.
A chapter focussed on practice presents the outcomes and analysis of my engagement with digital manufacturing technologies which resulted in the development of new tools to support Leach Tableware production and the interrogation of Leach forms, in different mediums, which led to the creation of Digital-Analogue Leach forms. The practice culminated in the design and development of new 21st century Standard Ware: a range of 9 forms, called Echo of Leach, that were developed by myself using digital and analogue methods: the designs were realised by myself, the Leach Studio, and a further four makers. The outcomes of the research were presented in a three month exhibition at the Leach Pottery in 2013.
The conclusions of the research draw on the key points raised in the analysis of the practice and relate these to the approaches to making pottery that are highlighted in the cultural heritage of Leach in the contextual review. These are also discussed in relation to ways in which these findings could be taken forward into development of knowledge about Standard Ware, especially in a broader studio pottery context

Michael Lewis: Journalist and Bestselling Author
No full textMichael Lewis is a New York Times bestselling author who has written more than a dozen books on subjects ranging from politics to Wall Street. His recently released book, Fifth Risk, explores mismanagement in federal government.
His other books include The Big Short, Moneyball and The Blind Side - all of which were made into movies. Another, Liar\u27s Poker, was based partly on his experience as a bond salesman at Salomon Brothers.
Lewis is a sharp observer of politics, finance and the evolution of American culture, combining keen insight with a sharp sense of humor. He is a columnist for Bloomberg News and a contributing writer to Vanity Fair. His articles have also appeared in The New York Times Magazine, The New Yorker and Sports Illustrated

Early Risk, Attention, and Brain Activation in Adolescents Born Preterm
No full textThe relations among early cumulative medical risk, cumulative environmental risk, attentional control, and brain activation were assessed in 15 – 16-year-old adolescents who were born preterm. Functional magnetic resonance imaging found frontal, temporal, and parietal cortex activation during an attention task with greater activation of the left superior-temporal and left supramarginal gyri associated with better performance. Individual differences in early cumulative risk are related to patterns of brain activation such that medical risk is related to left parietal cortex activation and environmental risk is related to temporal lobe activation. The findings suggest that early risk is related to less mature patterns of brain activation, including reduced efficiency of processing and responding to stimuli.This is the accepted version of the following article: Carmody, D.

Nickel laterite processing technologies – where to next?
No full textA review has been completed of current and proposed processing technologies for nickel laterite ores. Although future supplies of nickel depend on laterite ores, their processing is inherently energy intensive and expensive as, unlike sulphide ores, they cannot be significantly upgraded, meaning the entire ore needs to be treated in the process. In addition, hydrometallurgical processes in particular have significant waste disposal problems. However, new technologies are being developed that are attempting to address the current processing issues, including some innovative processes that are in their early stages of development.
Smelting is a well known and proven technology for saprolite ores that is continually being improved. It is a high energy consumer and needs to be performed on a large scale to be cost-competitive. It remains the most popular option for large scale developments based on saprolite ores and accounts for a significant amount of nickel production from laterite sources.
High Pressure Acid Leach (HPAL) remains the process of choice for treating limonite ores, especially for large scale developments. It has the advantages of high nickel and cobalt recoveries and is applicable to a wide range of ores. However, the process does suffer from significant waste disposal issues.
Atmospheric and Heap Leaching. Smaller scale developments are being actively pursued based on Atmospheric Leaching (AL) or Heap Leaching (HL) technologies. These processes do not rely on autoclave technology and are therefore perceived to be less capital intensive and easier to operate. However, they still require significant investment in terms of infrastructure. Heap leaching is the option most investigated, whereas AL is gaining momentum for mixtures of limonitic and saprolitic ores. Waste disposal issues are again significant.
Downstream Product Recovery. The two main downstream processing technologies for nickel recovery from solution are mixed hydroxide precipitation and mixed sulphide precipitation. Refining to pure nickel and cobalt products is an option in the large scale HPAL projects.
NEW TECHNOLOGIES
Hydrochloric Acid Leaching has been investigated on a laboratory scale for some time based on the fact that the acid can be reformed from the waste liquor by pyrohydrolysis or, more recently, distillation. In order to be competitive, these processes require that acid usage is minimised. However, aggressive leach conditions with high acid consumptions are still required to give good nickel recoveries. In some processes, waste disposal can be minimised.
Bioleaching of oxide ores is a concept that is in its infancy, but does offer some advantages over conventional processes. The process uses organic matter to produce organic acids in situ that leach the ore, possibly by-passing the need for expensive mineral acids, and reducing waste disposal problems associated with current processes
