Given rising electricity consumption, coupled with finite resources, ICT-enabled electrical networks such as smart grids are increasingly being deployed by energy companies. One part of smart grids is smart meter technology (SMT), which are digital electrical meters, having the potential to increase energy efficiency in both residential and industrial(More)
Clinical, bronchoscopic, spirographic, scintigraphic, and chemical analyses were done in 24 children with cystic fibrosis to assess the mucolytic effects of acetylcysteine inhalations versus L-arginine hydrochloride aerosols. The latter drug is less active than acetylcysteine and should not be used to treat children with cystic fibrosis.
Research on the adoption of information systems (IS) has been dominated by mechanistic motivational theories (extrinsic vs. intrinsic motivation). In contrast, the Self-Determination Theory (SDT) goes beyond the traditional dichotomy of extrinsic and intrinsic motivation by distinguishing between different types of motivation based on one's perceived(More)
The results of clinical trials investigating various therapies in acute ischemic stroke have been inconsistent. The effect of glycerol therapy and a combination therapy of glycerol and dextran was evaluated in a double-blind, placebo-controlled study. Repeated neurologic examinations (Day 0, Weeks 1, 6, 12, and 24) according to a modified Mathew score were(More)
In an empirical study, we explore success factors of electronic business models by comparing how the two professional social networking sites (SNS) LinkedIn and Xing have achieved competitive advantage. Using the grounded theory method and a resource-based perspective, our interpretative case study employs the business models of the respective organizations(More)
In children (mean age 12.1 +/- 2.9 years) with cystic fibrosis, 44 bronchoscopic examinations were done under general anaesthesia with muscle relaxation using a Friedel type ventilation bronchoscope. The endoscopic picture of the mucous membranes was compared with the state of the bronchial secretions, its bacteriologic findings and content of acid(More)
In the light of 8 observations, made by the authors, vasoanomalies underlying the syndrome of the unilateral hyperlucent lung are discussed in their correlation to homolateral bronchial lesions. There were 3 cases with unilateral aplasia of the pulmonary artery in which the unilateral hyperlucency was found always on the healthy side. In these cases there(More)
