OBJECTIVE To assess whether patients receiving opioid substitution therapy (OST) in general practice cause other patients sufficient distress to change practices--a perceived barrier that prevents general practitioners from prescribing OST. DESIGN, SETTING AND PARTICIPANTS A cross-sectional questionnaire-based survey of consecutive adult patients in the waiting rooms of a network of research ...

Abstract. The widespread dissemination of high-resolution flat-screen display devices will remediate the presentation of video, and therefore the aesthetics of video production. This technology will lead to new video aesthetics. The crafting of the new video will relate to the current television norms in ways similar to television's earlier relationship to the film aesthetic. Many techniques an...

Fall detection is a major challenge in the public health care domain, especially for the elderly, and reliable surveillance is a necessity to mitigate the effects of falls. The technology and products related to fall detection have always been in high demand within the security and the health-care industries. An effective fall detection system is required to provide urgent support and to signif...

Research in Ubiquitous Computing and Ambience Intelligence aims at creating systems able to interact in an intelligent way with the environment, especially the user. To be aware of and to react on the current situation usually a complex set of features describing particular aspects of the environmental state has to be captured and processed. Currently, no standard mechanisms are available to mo...

Post growth annealing of solution grown ZnO nanowire array is performed under controlled oxygen ambience. The role of annealing over surface defects and their consequence on dark/photo-conductivity and photosensitivity of nanowire array is investigated. Surface defect properties are explored using various measurement tools such as contact angle, photoluminescence, Raman spectroscopy and XPS mea...

The natural polyamines spermine and spermidine, and the diamine putrescine, were extracted from rooster testis cells separated by sedimentation at unit gravity, and from vas-deferens spermatozoa. The ratios spermine/DNA and spermidine/DNA were kept relatively constant throughout spermatogenesis, whereas the ratio putrescine/DNA rose in elongated spermatids. The cellular content of spermine, spe...

With the today’s state-of-the-art technology, miniature sensors and actuators can be manufactured and integrated with electronics onto extremely small footprint devices. Such devices could be embedded into different platforms, turning the ambience into a highly controllable, supportive, and cooperative environment. Applications of this technology can be easily envision in nearly every aspect of...

The support of smart interaction in ubiquitous computing is among the core criteria to achieve user acceptance and thus business success. We describe an architectural framework usable in various application domains to ease the interaction of the user with functions of devices in his ambience. We assume that the interaction is formalized through a service-oriented wrapping of the device function...

A localized surface plasmon resonance (LSPR) biosensor using surface relief nanostructures was investigated to evaluate the importance of target localization on the sensitivity enhancement. The LSPR device was modeled as periodic metallic nanowires with a square profile on a gold film and the target as a self-assembled monolayer in buffer solution. The numerical results using rigorous coupled-w...

We report a new production pathway for a variety of metal oxide nanocrystallites via submerged illumination in water: submerged photosynthesis of crystallites (SPSC). Similar to the growth of green plants by photosynthesis, nanocrystallites shaped as nanoflowers and nanorods are hereby shown to grow at the protruded surfaces via illumination in pure, neutral water. The process is photocatalytic...
