The Electronic Government is a new field of applications for the semantic web where ontologies are becoming an important research technology. The e-Government faces considerable challenges to achieve interoperability given the semantic differences of interpretation, complexity and width of scope. In this paper we present the results obtained in an ongoing(More)
No longer relegated to radio frequency (RF) engineers, antenna designers, and military applications, electromagnetic analysis has become a key factor in many areas of advanced technology. From 3 GHz PCs and wireless computer networks, to PDAs with Internet capabilities and the seemingly ubiquitous cell phone, it seems that electronic designs increasingly(More)
The level of the renin-angiotensin-aldosterone system (RAAS) activity in kidney transplant recipients has not been extensively studied or serially profiled. To describe this axis and to determine its association with glomerular filtration rate (GFR) change, interstitial expansion, and end-stage renal disease (ESRD), we measured plasma renin activity (PRA)(More)
