Fifteen nosocomial cases of extended-spectrum β-lactamase-producing Klebsiella pneumoniae occurred among 132 neonates in a premature intensive care unit in Hungary in June through November 1998. Fourteen strains were indistinguishable by molecular biological typing and harbored the same single conjugative extended-spectrum β-lactamase-encoding plasmid that was spontaneously found in a Serratia marcescens strain in the same patient.
In our paper we would like to present a threedimensional model of a virtual library created by exploiting the capabilities of the Virtual Collaboration Arena (VIRCA) system. Based on the classification system elaborated by Callimachus we focus on the field of Greek poetry and drama in the 3rd century BC, and select some illustrious ancient authors and texts for the content of a virtual library. In order that the presented content should be appropriately searchable we attach certain (verbal and/or multimedia) metadata to the English translation of the selected ancient Greek texts and using them to form a wellsearchable spatial hypertext system. In addition to our three dimensional virtual library model, we have created its hypertext (two-dimensional) representation which can further emphasize the additional features that the three dimensional representation provides for us. Finally we outline the possible improvements of the system which indicate the creative potentials and hidden assets that lie in the construction of a library system of this type.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
