Korrosionsprobleme traten an den Kesselwän­ den von Wirbelschichtkesseln auf, in denen 100 % Altholz unter „Low-NOx­Verhältnissen“ verbrannt wurde. In einem ersten Schritt zum Verständnis der Auswirkungen des Brennstoffs wurden Ablagerungen an verschiedenen Positi­ onen der unteren Kesselwände gesammelt und analysiert. Ein großer Teil dieser Kesselwände war mit der Nickel-Basis-Legierung Alloy ...

BACKGROUND Paediatric ENT services in regional areas can be provided through telemedicine (tele-ENT) using videoconferencing or with a conventional outpatient department ENT service (OPD-ENT) in which patients travel to see the specialist. The objective of this study was to identify the least-cost approach to providing ENT services for paediatric outpatients. METHODS A cost-minimisation analy...

The tele-educational environment is build around the metaphor of a college. The virtual college offers the opportunity for students to participate in desktop tele-education from their homes or offices. The environment is based on In...

This paper examines a number of key areas of current research in tele-operated robotics that could have a significant impact on future directions and applications. Although accurate prediction is notoriously difficult the paper will aim to ground its conclusions through reference to current research literature. Following a generic description of the key elements in tele-robotic systems, the pap...

This paper describes an overview of telemedicine applications in ophthalmology and at the same time to provide background information on new tele-ophthalmological applications and the use of tele-Ophthalmology. Few urban areas for their population, no access/ very less access to tertiary eye care. In order to make eye care services accessible to every one, the concept called “Teleophthalmology”...

Assuming that, given the processes of technology diffusion, adolescent behavior forecasts future consumption of digital information, it would seem pertinent to study the characteristics of teenager technology use. This research asks: What are the key patterns regarding the use of technology platforms by teenagers? Is technology usage among teenagers shaped by schools' disparate teaching philoso...

The Tele-Medicine sub-services backed up by a novel, open-architecture Tele-Working platform, are evaluated. This multimedia platform, developed over the Hellenic Integrated Services Digital Network (ISDN), is based on user terminals (personal computers), networking apparatus, and a central database. The developed product equips the Hellenic PTT Organization (OTE) with a ready-to-be applied nov...
