Object-Oriented Software Representation of Polymer Materials Information in Engineering Design

The software application POISE, Polymer Objects in a Smalltalk™ Environment, integrates knowledge representation, user interfaces, and data management; a system of tools for the materials domain expert involved in design. Engineering design solutions initially build from generalisations. POISE represents multiple levels of generalisations from classifications of polymer information. The class-instance paradigm classifies software objects. An object’s behaviour is an exclusive function of its class. Polymer’s behaviours are a function of multiple orthogonal factors, like chemistry and processing, therefore multiple orthogonal classes must represent polymers. Taxonomy only represents one of these factors. The Enhancer mechanism resolves this conflict between classification and representation. Polymer classification is not well established, with new materials evolving. The software compensates by evolving the classification schema. Guided with a specialised interface tool, the domain expert updates the schema by adding new polymer families and re-classifying existing classes. Through analysing the generalisations in the classification, the domain expert can develop an appropriate classification. This analysis relies on the engineering properties differentiating the principal material qualities. Standard properties do not distinguish specific structural differences in polymer materials, necessitating new properties. Material properties distinguish materials in the domain whereas the classes describe the properties of polymer objects. Domain experts add new properties to the polymer classes to distinguish polymer objects. Properties are independent objects that partially describe the class template; Partial Template Objects. Persistence of personal design information and management of shared data requires dichotomous database management. Shared data requires multi-user access, and consequently transaction management. Transaction management in object-oriented systems often holds resources for a long duration. Transaction declaration hinders transparent access to storage, and corrupts the representation. For single-user design information, transactions are implicit with access. Database proxies provide transparent per-object transaction management to persistent design information. The WorkBase is an object-storage utility that utilises Enhancers as proxies

Lone Madrone Winery and Bristols Cider

Neil Collins, the award winning wine maker at Tablas Creek and Lone Madrone wineries, is originally from Bristol, England, where he grew up enjoying apple ciders. This case follows his transition from the culinary to wine industry, and how he learned wine making from some the best wine makers in the Central Coast of California to become the head wine maker at an established winery and part owner of his own smaller winery. The case also explores how his cider making hobby became a commercial business, and the growth of the fledgling US cider industry

Grazing and control of coral reef community structure by Diadema antillarum Philippi (Echinodermata: Echinoidea): A preliminary study

The grazing activities of the tropical echinoid Diadema antillarum Philippi can markedly influence the structure of the shallow-water epibenthic coral reef community. The elimination of an entire Diadema population from a patch reef in St. Croix, U.S. Virgin Islands resulted in a great increase in macro-algal biomass, alterations in species composition, shifts in dominance, an increase in species numbers, and a decrease in equitability...

‘Standing by’: disability hate crime and the police in England

This article discusses the Don’t Stand By: Hate Crime Research Report (DSB) (Mencap, 2011), which documents failings in policing practices related to reporting and responding to disability hate crime. Such failings, we argue, constitute not so much direct discrimination but acts of ‘normalcy’. Normalcy is the process whereby taken for granted ideas about what is normal become naturalised; in this respect being non-disabled is seen as normal. Acts of normalcy, whilst less tangible, are by no means less violent or harmful than acts of ‘real discrimination’ or ‘real violence’ (Goodley and Rumswick-Cole, 2011). Systemic and cultural normalcy within the police is not new, as can be seen in the case of Stephen Lawrence

The perceptions of new to role detective officers in relation to their professional accreditation in a northern police service

This thesis analyses the professional accreditation of new to role detective officers between June 2010 and September 2013 who were studying for a foundation degree through a local university whilst engaged on a police Professionalising Investigation Programme (PIP) situated in a northern police service. It considers the perceptions of the trainee detectives learning experience in relation to professional development and questions their experience regarding their overall work-based learning placement. Higher education and culture are both individually and organisationally explored regarding the effect on the trainee detective along with the concepts of profession, professionalisation and professionalism that are examined in the wider context of policing which are then contextualised to the PIP process and perspectives of the trainee detective. An initial survey questionnaire revealed themes inclusive of supervisory and organisational issues regarding learning cultures and placement with tutors in the workplace. These were further refined for the interview stage. This thesis then utilised Bourdieu’s concepts of habitus, field and cultural capital and Lave and Wenger’s Community of Practice (CoP) as analytical tools to understand the perceptions and the participation of the trainee detective in a work-based environment. Though for some trainee detectives their learning experience presented a positive outcome, for others, feelings of isolation and conflict, influenced and routed by organisational culture to learning were apparent. The trainee detectives therefore experienced a diverse programme of professional development and inequality of process, yet demonstrated resilience even though for some their placement in investigation departments was not construed as a haven of peace. This thesis argues that the PIP programme, and the collaboration with a local university, provided an overall opportunity for continuous professional development for the trainee detective enhancing their cultural capital whilst increasing the status of the police service as a more professional and structured organisation

Iron solubilization during anaerobic growth of acidophilic microorganisms with a polymetallic sulfide ore

Acidithiobacillus ferrooxidans at 30 °C and Sulfobacillus thermosulfidooxidans at 47 °C were selected from a preliminary screening of various acidophiles for their ferric iron reduction capacities during anaerobic, autotrophic growth on sulfur. The selected cultures were used with a polymetallic sulfide ore under anoxic conditions to demonstrate enhanced solubilization of iron during leaching in shaken flasks and enhanced removal of iron from laboratory ore-leaching columns, compared to leaching with continuous aeration. Ore-associated, ferric iron-rich precipitates, which were formed under previously oxidizing conditions, were a potential influence on extraction of target metals and percolation through ore columns and were available as the source of ferric iron for anaerobic sulfur oxidation. Over twice as much iron was removed by moderate thermophiles when anoxic phases were introduced during the leaching. Enhanced removal of iron and some improvement in extraction of base metals from ore fragments were also demonstrated with a selected "Sulfolobus"-like strain during growth and leaching with alternating periods of aeration and anoxic conditions at 70 °C
