organophosphorus compounds are known to inhibit the esteratic site of acetylcholinesterase by phosphorylation. the phosphorylated esteratic site of acetylcholinesterase undergoes hydrolytic regeneration at a slow or negligible rate. nucleophilic agents such as hydroxytamine, hydroxamic acids, and oximes reactivate the enzyme more erapidfy than does spontaneous hydrolysis. the red cell cholinest...

We consider new objects in bosonic open string theory – ND tadpoles, which have N(euman) boundary conditions at one end of the world-sheet and D(irichlet) at the other, must exist due to s− t duality in a string theory with both NN strings and D-branes. We demonstrate how to interpolate between N and D boundary conditions. In the case of mixed boundary conditions the action for a quantum partic...

Preface My interest in mobile systems and hypermedia precedes my Ph.D. project by several years. I developed, together with my study group, my first hypermedia system in the autumn of 2000 as part of the Hypermedia course at Aarhus University. The system was a compiler engine written in Python which could compile guided tour maps created with the Webvise open hypermedia system (Sandvad et al., ...
