False-belief reasoning, defined as the ability to reason about another person's beliefs and appreciate that beliefs can differ from reality, is an important aspect of perspective taking.

All age groups had difficulty suppressing their own knowledge when es...

10 Quantification of electroinactive dopants in conductive polypyrrole (PPY) films was performed with electrochemistry combined on-line with inductively coupled plasma-atomic emission spectrometry (EC/ICP-AES). Anion (HSO4−) ejection out of a PPY film was first chosen as a model system and the results obtained with EC/ICP-AES were found to be comparable with values deduced by electrochemical qu...

From about the mid-1980' s to the mid-1990' s there was a flurry of research activity in the area of database triggers and constraints, seeing the development of numerous research proposals and prototypes. Soon thereafter, most mainstream database products ramped up their support for constraints and triggers, with expressive constraint specifications appearing in the SQL-92 standard, and both c...
