An intelligence support system has been developed using open hypermedia architecture. This approach integrates information from distributed disparate sources into a knowledge base. A public interface supports access by external applications. Filtering and change detection functions have also been implemented. The approach has shown promise in multiple domains, indicating possible wide applicati...

Pre-main sequence stars in the Orion-Monoceros Complex are either distributed in groups closed associated with dense cores, or dispersed along molecular filaments. Some molecular clouds are apparently affected by the OrionEridanus Superbubble created by the Wolf-Rayet winds and supernovae from the OriOB1 association, whose shock fronts compressed and triggered starbirth in adjacent molecular cl...

N-Acetylcysteine (H2NAC) is a potent antioxidant, a precursor for cysteine and glutathione, and a potential antidote against certain metal ions such as cadmium and mercury. Little is known about the structural aspects of complexes formed between Hg(II) and N-acetylcysteine, despite many biological tests on its ability to bind to organic and inorganic mercury, and a few reports on formation cons...

Both deoxyribonucleic and ribonucleic acids appear to possess a secondary structure, by virtue of the fact that the purine and pyrimidine bases can undergo hydrogen bonding with each other. In the case of DNA, this secondary structure takes the form of a long, highly ordered helix composed of two strands held to each other by hydrogen bonds between the bases (l-3). The secondary structure of RN...

Abstract: We present a multi-level formation model for complex software systems. The previous works extract the software systems to software networks for further studies, but usually investigate the software networks at the class level. In contrast to these works, our treatment of software systems as multi-level networks is more realistic. In particular, the software networks are organized by t...

A proximity effect in arene ^-complex formation from the reaction system of an aryl G r i g n a r d reagent and anhydrous chromic chloride was investigated. The yields of arene ^-complexes and any accompanying reaction products were compared by the systematic variation of the aryl G r i g n a r d reagent employed. Phenyl G r i g n a r d gave the best yield of jr-complex followed by the benzyl, ...
