Two novel fluorescent probes based on triphenylamine (TPC) and phenanthro(9,10-d-imidazole) (PITP) have been synthesized and studied as cyanide selective indicators in aqueous media. Complete colour bleaching was observed due to the nucleophilic addition of cyanide to the 2-vinylmalononitrile of TPC, which results in the disruption of the extended conjugation and turns off the intramolecular ch...

This paper discusses the recent Geo-ICT developments, such as information system modelling standards, database technology, global positioning systems, Internet development, wireless communication and acceptance of geometry standards within general ICT tools and its uses on cadastral systems.

Since its launching in 1974, the Human Choice and Computers (HCC) series of conferences of the IFIP Technical Committee 9 (TC9) has provided a forum for the study of the multiple facets of the dynamics of social change associated with information and communication technologies (ICTs). These conferences have captured the unfolding hopes and concerns about the interplay between the technologies w...

The focus of this study was to investigate the relationship between: (1) information communication technology (ICT) operational risk management (ORM) and (2) performance of small to medium enterprise (SME). To achieve the focus, the research investigated five specific research objectives that included the principal causes of ICT ORM failure in SME: change management requirements; characteristic...
