The Folly
No full textCatalogue of an exhibition held at Gallery 1, Grantpirrie, Redfern, N.S.W., 5-28 February 2009."The Folly is a three-screen digital work in which Arlo Mountford has animated three paintings by the sixteenth century Flemish artist, Pieter Bruegel the Elder. Using the computer, Mountford redrew the genre paintings The Corn Harvest (1565), The Hunters in the Snow (1565) and Landscape with the Fall of Icarus (c1558)"--Website.Catalogue essay by Zara Stanhope
Redfern kids connect : technology and empowerment
No full textRedfern Kids Connect is a community technology project that has run in inner-city Sydney since 2002. Redfern is known to many as the heart of urban Aboriginal Australia and as a diverse community facing challenges around poverty, crime and race relations. For three years, children (8-12 years old), and volunteers (university students and young professionals) have met each Saturday to play on computers and socialise. The project’s experiences with relationships, technology, and empowerment have been as confusing as they have been exciting. In the spirit of action research, this thesis explores the impacts the project has had. Uniquely embedded in the process of reflection occurring away from its on-the-ground activities, it tells the project’s story through the eyes of its volunteers. The research concludes that the project's main contributions to empowerment have been through building social capital (Cox, Putnam) and improving new forms of literacy (Warschauer). Vital to supporting and extending these outcomes have been taking a social approach to supporting technology use, shaping a safe and open environment (Marvin et. al), supporting critical thinking and expression (Freire) and examining the project 'behind the scenes'. The author takes the dual role of researcher and participant in the research
A comparative study on suitability of model-free and model-fitting kinetic methods to non-isothermal degradation of lignocellulosic materials
No full textThe thermal kinetic modeling is crucial for development of sustainable processes where lignocellulosic fuels are a part of chemical system and their thermal degradation eventuates. In this paper, thermal decomposition of three lignocellulosic materials (bagasse, rice husk, and wheat straw) was obtained by the thermogravimetric (TG) technique and kinetics was analyzed by both model-fitting and isoconversional (model-free) methods to compare their effectiveness. Two models selected from each class include Arrhenius and Coats–Redfern (model-fitting), and Kissinger–Akahira–Sunose (KAS) and Flynn–Wall–Ozawa (FWO) (model-free). The formal model-fitting approach simulating the thermal decomposition of solids by assuming a fixed mechanism was found to be unduly facile. However, activation energy (E) values calculated from two model-fitting techniques were considerably different from each other with a percentage difference in the range of 1.36% to 7.65%. Particularly, both model-fitting methods predicted different reaction mechanism for thermal disintegration of lignocellulosic materials (two-dimensional diffusion (D2) by Arrhenius and one-dimensional diffusion (D1) by Coat–Redfern method). Conversely, the model-free routine offers a transformation of mechanism and activation energy values throughout reaction and is, therefore, more authentic to illustrate the complexity of thermal disintegration of lignocellulosic particles. Based on the model-free kinetic analysis, the lignocellulosic materials may be devised in following order of activation energy: rice husk > bagasse > wheat straw, by both KAS and FWO methods with a percentage difference no more than 0.84% for fractional conversion up to 0.7. Isoconversional approach could be recommended as more realistic and precise for modeling non-isothermal kinetics of lignocellulosic residues compared to model-fitting approach.Rivers, Ports, Waterways and Dredging Engineerin

PCDDB: the Protein Circular Dichroism Data Bank, a repository for circular dichroism spectral and metadata
No full textThe Protein Circular Dichroism Data Bank (PCDDB) is a public repository that archives and freely distributes circular dichroism (CD) and synchrotron radiation CD (SRCD) spectral data and their associated experimental metadata. All entries undergo validation and curation procedures to ensure completeness, consistency and quality of the data included. A web-based interface enables users to browse and query sample types, sample conditions, experimental parameters and provides spectra in both graphical display format and as downloadable text files. The entries are linked, when appropriate, to primary sequence (UniProt) and structural (PDB) databases, as well as to secondary databases such as the Enzyme Commission functional classification database and the CATH fold classification database, as well as to literature citations. The PCDDB is available at: http://pcddb.cryst.bbk.ac.uk
