background numerous factors have an effect on the accuracy of an impression and resultant cast, and these include: impression material, impression technique, tray selection, impression disinfection, storage time of impression before pouring, stone type used for fabrication of cast. up to now, there has been little research conducted on the effect of contact time of a cast with an impression, on...

BACKGROUND The use of an oscillating saw for cast removal creates a potential for iatrogenic injury and patient discomfort. Burns and abrasions can occur from the heat created by frictional forces and direct blade contact. With use of a cadaver model system, skin temperature measurements were recorded during cast removal with an oscillating saw. METHODS Casts of uniform thickness were applied...

The 3D cubic puzzle is implemented in a head-coupled cubic display, pCubee[6], that allows users to view a 3D scene from different sides. The display is compact and light enough to be held in one hand by an average adult user. By coupling the display with a 3D stylus, pCubee supports the bimanual Kinetic Chain (KC) model [4] for the cubic puzzle task. Users can hold pCubee in their nondominant ...

In this research the relationship between graphitization ability and the carbon equivalent (CE %) of a cast iron have been investigated. The first series of moulds were cast at CE of 3.2% and pouring temperature of 1350°C. The other moulds were cast at different CE% with varying Si content. The graphitization ability( c ) was calculated using the thermodynamics aspects of graphitization and CE%...

Taxpayers face well-known and well-identified individual motivations in their compliance decisions, motivations that originate with the standard economic model of tax evasion in which financial incentives are shaped by audit, penalty, and tax rates. However, there is growing evidence that these individual incentives, while important, are not always decisive. Individuals do not always behave as ...

A recently much debated issue is why observed investment and growth rates in poor countries are lower than traditional theory predicts. Empirical evidence suggests that social and political instability is a major reason for the divergence between poor and rich countries. However, there is still the unsolved puzzle that the relationship between development and investment rates is not monotonic b...

To the Editor, The Indian Medical Gazette StR,?I have read with considerable interest your leading article on epidemic dropsy in the October issue of the Gazette. I wish to draw your attention to one or two points in connection with your reference to our work on the subject. While offering criticism on the deductions made by us from our experiments you make no mention of the fact that albumin w...
