This article contains the results produced by an international group of industrial managers, engineers, consultants and researchers who came together in a Roundtable meeting to formulate recommendations for integrating people, organization, and technology in modem advanced manufacturing environments. The wink of this Roundtable was focused on identifying what human factors knowledge manufacturing industry should be applying now to improve its competitive position. The Roundtable also proposed a R&D framework and agenda for the future which is aimed at ensuring that industrial and government funded research is directed at areas where industry can derive benefits or where deficiencies exist in relation to the design and operation of advanced manufacturing enterprises. Many specific ideas that industry can act upon immediately are presented and 43 areas for future research are identified and discussed. [ABSTRACT FROM AUTHOR]

Discusses the effect of threading dislocations on electron transport in In[sub 0.24]Ga[sub 0.76]N/GaN multiple quantum wells using transmission electron microscopy and van der Pauw Hall effect measurements. Decrease in Hall mobility as the temperature decreases due to the threading dislocation scattering.

Abstract: Hydrous Al2O3–TiO2 (78:22 in molar ratio) gel was fired at various P–T conditions using a piston-cylinder apparatus and identified by XRD, FTIR, optical microscopy and electron microscopy. Below 675°C, the sample remained amorphous at ambient pressure, yet transformed at 1.5kbar to Ti-doped tohdite, which is elongated along the crystallographic c-axis, with well-developed (0001) base and ledges. Tohdite has a significant water/hydroxy content and is therefore susceptible to pore coalescence parallel to the basal layer upon electron dosage. Tohdite also contains Ti4+ up to 3at.%, which replaces Al3+ in tetrahedral and/or octahedral sites to form superstructures and defect microstructures. In contrast, a higher T–P condition (above 675°C and 8kbar) caused the formation of more stable Ti-doped corundum, which is hexagonal-rhombohedral in shape and in epitaxial association with rutile nuclei. Ti-doped tohdite and corundum shed light on a sol–gel route for their occurrence in peraluminous metamorphic rock. The nanoporous and nanodelaminated tohdite may have potential catalytic applications. [Copyright &y& Elsevier]
