Introduction The design of metal organic co-ordination polymeric materials have been deeply researched. In recent years, the studies of co-ordination polymers have made much progress. Such polymers are prepared by polymerization of bis ligand and metal ions. Most of the co-ordination polymers are reported based on bis-salicylic acid, bis-salicyaldehyde and bis-oxine.[16] One of the area in whic...

The geographic concepts of region and scale can be preserved in semantic information spaces and depicted cartographically. Region and scale are fundamental to geographical analysis, and are also associated with cognitive and experiential properties of the real world. Scale is important when graphically representing a spatialization, as it affects the amount of detail that can be shown. Latent s...

Operational design co-ordination has been identified as the basis for an approach to engineering design management that is more comprehensive than those that currently exist. As such, an integrated and holistic approach to operational design co-ordination has been developed that enables design to be managed in a coherent, appropriate and timely manner. Furthermore, the approach has been impleme...

This paper presents a holonic co-ordination server which is made up of a recursive hierarchy of three different agent types: On the top stands an agent providing matchmaking services and representing the co-ordination server to the outside. It passes incoming requests to a subordinated agent type that is equipped with co-ordination mechanisms such as auctions, negotiations and coalition formati...

The arylxenonium cation in the salt [C6F5X e]+ [AsF6]" is isoelectronic to C6F5I, but coordinatively unsaturated with respect to N-bases like MeCN and pyridines. Co-ordination of strongly basic pyridines causes weakening of the Xe-C bond and C6F5 radical formation. The thermal decomposition of pyridine co-ordinated arylxenonium cations gives three groups of products: C-pentafluorophenylated pyr...
