An Approach for Managing Data in Cloud Using Resource Description Framework (RDF)
Abstract: Despite of late advances in appropriated Resource Description Framework information administration, handling a lot of RDF information in the cloud is still exceptionally difficult. Many of the original semi-structured data promises, such as flexible structure, optional schema, and rich, adaptable URIs as a basis for information sharing, are poised to be fulfilled by the W3C's Resource Description Framework (or RDF, for short). Furthermore, RDF is in a unique position to …

Effectiveness of Foot Massage on Pain among Patients Who Underwent Abdominal Surgery
Abstract: AbstractPain after surgery is common, normal and to be expected. Steps can be taken to minimize or eliminate pain, but pain that gets worse, especially if other symptoms are present, can be a sign of a surgical complication. Patients routinely report mild to moderate pain even though pain medications have been administered. Complimentary strategies based on sound research findings are needed to supplement pharmacological management. Foot massage has the potential …
