Eight strains of C. elegans, including seven recombinant inbred (RI) strains with mean life spans ranging from 10.9 to 28.8 days, were reared under two conditions (95% oxygen or methyl viologen) known to elevate the concentration of free radicals. Both agents inhibited development, as ascertained by measuring the lengths of animals at regular intervals. The(More)
The enormous volume and rapid growth of resources available on the World Wide Web as well as the emergence of numerous metadata schemas have spurred a re-examination of the way subject data are provided for Web resources. There is broad agreement that a subject schema for metadata must exhibit both simplicity and interoperability. Simplicity refers to the(More)
This paper describes a prototype for a Web service that translates between pairs of metadata schemas. Despite a current trend toward encoding in XML and XSLT, we present arguments for a design that features a more distinct separation of syntax from semantics. The result is a system that auomates routine processes, has a well-defined place for human input,(More)

This study examines Dublin Core (DC) metadata semantics drawn from the perspectives and experiences of cataloguing and metadata professionals. The study ascertains the extent of difficulty in applying the DC metadata elements encountered by these professionals and examines factors engendering such difficulties during the metadata application process.(More)
This paper presents an approach for providing terminology Web services for controlled vocabulary terms. Services are implemented within a service oriented framework. A set of experimental services for genre vocabularies is provided through the MS Office Research pane, a built-in feature of Internet Explorer (IE) when users have loaded MS Office 2003. Web(More)
