Health-related quality of life (HRQoL), conceptualized as patients' own evaluations of their health status, is an important criterion in evaluation health and health care and in the treatment of individual patients. Until now, few systematic attempts have been made to develop instruments to assess the HRQoL of children using such a conceptualization. This(More)
OBJECTIVE To examine the impact of previously operated complex congenital heart disease on health related quality of life and subjective health status and to determine the relation between these parameters and physical status. DESIGN Cross sectional; information on medical follow up was sought retrospectively. SETTING Patients were randomly selected(More)
Agent technology provides industrial-applications developers with new abstractions for distributed-system development, new methodological tools, and a set of algorithms for creating autonomous, collaborative systems. Over the past few years, a number of industrial applications have deployed agents. However, a substantial gap still exists between the(More)
— Distributed generation (DG) of electricity is providing an increasing part of the worldwide electricity supply. At the same time, there is a big potential of demand response resources. When — in a geographical area or in the contract portfolio of an energy trader — the number of these Distributed Energy Resources (DER) increases, clustered control of DER(More)
Cranial radiation therapy in childhood acute lymphoblastic leukaemia has been associated with adverse neuropsychological effects, such as low intelligence. However, records show that these associations usually occur when the dose of radiation used is 2400 cGy. We investigated whether a lower dose of 1800 cGy had the same adverse effects on long-term(More)
We tested the hypothesis that, in patients with clear airways, the anatomical position of three single-use extraglottic airway devices is similar. The airways studied were: the laryngeal mask airway unique (LMA-U), the Softseal laryngeal mask airway (SS-LM) and the Cobra perilaryngeal airway (Cobra-PLA). Three hundred spontaneously breathing patients were(More)
—Response of demand, distributed generation and electricity storage (e.g. vehicle to grid) will be crucial for power systems management in the future smart electricity grid. In this paper, we describe a smart grid technology that integrates demand and supply flexibility in the operation of the electricity system through the use of dynamic pricing. Over the(More)
