introduction: the aim of this in vitro study was to evaluate the effect(s) of three canal lubricants i.e. sodium hypochlorite, rc-prep as the paste form of ethylenediaminetetraacetic acid (edta) and aqueous edta, on the occurrence/incidence of fracture, deformity and metal slivering of protaper rotary instruments. methods: a total of 120 mesial canals ( i.e. mesiobuccal and mesiolingual) of fir...

BACKGROUND The NDF-RT (National Drug File Reference Terminology) is an ontology, which describes drugs and their properties and supports computerized physician order entry systems. NDF-RT's classes are mostly specified using only necessary conditions and lack sufficient conditions, making its use limited until recently, when asserted drug-class relations were added. The addition of these assert...

This paper describes IBIS, a distributed file system for a network. of UNIX machines. IBIS provides two levels of abstraction: file access transparency and file location transparency. File access transparency means that all files are accessed in the same way, regardless of whether they are remote or local. File location transparency hides the location of files in the network. IBIS provides a si...

Linking drugs and their indications can helpt improve the quality of electronic medical records (EMRs) and facilitate clinical decision support. We investigate an automatic approach to extraction of indications for marketed drugs from drug package inserts. Our aim is to build a reference table that associates medications and their indications. This resourcecould facilitate maintenance of medica...

continuation of the Pharmacology/Toxicology (Pharm/Tox) Database formerly maintained by the National Gene Vector Laboratory. The purpose of the database is to provide gene therapy investigators with a catalog of gene therapy biodistribution and toxicology studies on file with the US Food and Drug Administration (FDA). Pharm/tox refers to any in vitro or animal study that seeks to determine the ...

PURPOSE: Despite the high rates of drug selling among youth in juvenile justice and youth residing in disadvantage neighborhoods, relatively little is known about the patterns of illicit drug selling among youth in the general population. METHODS: Using the public-use data file from the adolescent sample (N = 17 842) in the 2008 National Survey on Drug Use and Health (NSDUH), this study employ...

File format obsolescence is a major risk factor threatening the sustainability of and access to digital information. While the preservation community has become increasingly interested in tools for migration and transformation of file formats, the National Library of Australia is developing mechanisms specifically focused on monitoring and assessing the risks of file format obsolescence. This p...

The Global Unified Parallel File System (GUPFS) project is a five -year project to provide a scalable, high -performance, high -bandwidth, shared file system for the National Energy Research Scientific Computing Center (NERS C). This paper presents the GUPFS testbed configuration, our benchmarking methodology, and some preliminary results.
