Sheet metal and automotive industries need to continually improve their strategic competitive advantages with flexibility and cost-effectiveness to remain competitive in a changing world economy. In order to achieve this, the primary objective in the proposed research is to design and develop a knowledge-based process planning system for non-symmetrical products produced by deep drawing processes. This objective will be achieved by investigating the effect of process variable on drawability of sheet material, by obtaining relevant process information through necessary experimentation and finite element analysis and by development of a rule base by acquiring process information from domain experts selected from number of sheet metal manufacturing industries.Read moreRead less

This project will initiate and establish a collaborative research program between Professor Wojciech Z. Misiolek of Lehigh University (Bethlehem, PA, USA) and Professor Graham Schaffer at The University of Queensland. Professor Misiolek will spend an extended six month period at The University of Queensland.

Mechanistic Studies on Biologically Active Iron Chelators. The need for orally effective drugs as alternatives to invasive treatment regimens such as subcutaneous infusion is an ongoing concern in health care. This is particularly true in people suffering iron overload. In many cases this condition is present at birth and thus the administration of vital iron chelation therapy via the oral route is a much preferred option. We have unearthed a novel series of candidates for iron chelation therapy ....Mechanistic Studies on Biologically Active Iron Chelators. The need for orally effective drugs as alternatives to invasive treatment regimens such as subcutaneous infusion is an ongoing concern in health care. This is particularly true in people suffering iron overload. In many cases this condition is present at birth and thus the administration of vital iron chelation therapy via the oral route is a much preferred option. We have unearthed a novel series of candidates for iron chelation therapy (the pyridine-2-carboxaldehyde isonicotinoyl hydrazone [PCIH] analogues) which show oral activity. These chelators undergo some interesting iron catalysed oxidation chemistry and it is vital that the mechanism of this reaction be elucidated to determine whether it will be of biological significance upon administration of these compounds as iron chelators.Read moreRead less
