Grain refinement of pure magnesium using rolled Zirmax® master alloy (MG-33.3ZR)

Owing to the limited solubility of zirconium in molten magnesium, almost all of the zirconium contained in the Zirmax® master alloy (Mg-33.3Zr) is present in the form of nearly pure zirconium particles. Of them, zirconium particle clusters and individual zirconium particles greater than 5

Jack of all trades, master of some ...or none? Training teachers in Integrated Arts

This article reports on the integration of music with other ‘Arts’ in teacher training at a South African university where a challenge tertiary educators face is how to successfully integrate music within the Arts and Culture learning area of the school education system. The article firstly provides a brief background to the South African educational context. Secondly, it outlines current practices in the in the implementation of the integrated arts curriculum in schools and teacher training. Thirdly, it discusses pertinent issues and challenges in relation to team teaching, integration and curriculum change in teacher training. Given the constraints and opportunities that universities currently experience, this article investigates and reports on the issue of whether students should be trained as Jack of all trades and master of some…or none or Master of one trade and Jack of some with regard to integrating the Arts.

Master of Montsalvat

A study of the creation by the charismatic artist and architect, Justus Jorgensen, of an artists' colony at Montsalvat, Eltham, in the early 1930s. A comprehensive examination of this enterprise had not previously been attempted. The research unexpectedly revealed the community's close but clandestine association with psychoanalysis, which had intruded into every aspect of the artists' lives.

The master of talkback radio

A case illustrates why politicians like talkback radio. By going on talkback they can appear to be available in an open and unstructured forum, reaching out over the heads of the media to constituents. But far from being open and unmediated, talkback is a highly controlled and contrived forum. Guests like John Howard have the last word, and talkback hosts, Jon Faine included, make sure that they get it. As quantity always seems to win out over quality in mainstream radio, and brevity over depth, the emphasis is on giving as many callers as possible the chance to ask a question. The result is a few rushed seconds of questioning from the caller and a couple of minutes of spin in return from the politician, with no chance for the caller to push the issue further.

Master planned estates : parish or panacea?

Master planned estates in Australia emerge from two major directions: one aims to address the inadequacies of 1970s suburbanisation and the other comes from governments and developers seeking to realise alternatives. The very idea of master planning has a longer history, one that arguably dates back to 19th-century Utopian Socialism and Baron Haussmann's redesign of Paris, which involved a large-scale, comprehensive alternative vision realised by a sanctioned authority. Master planning thereby partakes of both utopianism and authoritarianism. These associations have infused the discussion and construction of Australian master planned estates rendering them both pariah and panacea. But research and my own experience suggests that they are far more panaceas than pariahs.

The intriguing and forgotten international exchanges in the master plan for the reconstruction of Skopje

At 5:17AM on Friday 26 July 1963, Skopje was struck by an earthquake, which in 17 seconds destroyed approximately 75% of the urban fabric, and changed the course of its history from an unknown town to a city of international focus. Immediate actions and a formidable level of local organization; an unprecedented pouring in of aid from the other Yugoslav republics and from individual nations and organisations; and a monumental role for the United Nations in the co-ordination of international , architectural and urban planning expertise for the city's large-scale and long-term reconstruction, laid the foundation for what has been called 'a precise Marxist revolutionary situation' .1 The detail of the paper concerns Stage 4, Replanning 1963 to 1966 of the planning strategy that was organised into five stages, and has a major interest in the invited United Nations (UN) international competition ~o redesign approximately two square kilometres of the city centre.2 Action is associated with activity as productivity, but in Skopje added to this were symbolic human acts and heroic action such that its inhabitants regained their city and importantly a new position as city in the world.

Kenzo Tange's forgotten master plan for the reconstruction of Skopje

After the 1963 earthquake, which is said to have destroyed seventy-five per cent of the urban fabric, Skopje, capital city of the Republic of Macedonia (then in Yugoslavia) became a centre of architectural activity. The United Nations held a limited competition for the reconstruction of Skopje, inviting four foreign firms and four Yugoslavian firms to participate. Tange's submission received sixty per cent of the first prize, co-operating with Yugoslav architects to develop the design idea. What can this project tell us about modernism re-inscribed in Japan, and the kinds of internationalism that the United Nations constructed? Japanese Metabolism, of which Tange was a pioneer, heralded Japan as a new centre for innovation in architecture; a new nationalism re-oriented the suffering after Hiroshima and Nagasaki. Tange developed and realised in Skopje the striking planning ideas he began in his Tokyo Bay proposal. This article examines Tange's master plan for Skopje. It argues that his key elements, the City Wall and the City Gate, exemplify Tange's drive for a new vision in the context of destruction, and that these remain definitive elements today even in the context of a messy transition from a communist to a capitalist society.
