The quality of life and the cognitive performance of patients with extracranial carotid stenosis were investigated 8–11 years after treatment in 18 non‐operatively treated patients and 44 patients treated with carotid endarterectomy. The cognitive performance was compared with data on a normal control group. Cognitive performance was assessed with neuropsychological tests and the quality of life by personal interview based on a questionnaire. Most of the carotid stenosis patients recovered well both subjectively and cognitively regardless of the type of treatment. Only the subgroup operated twice was subjectively worse compared to the other groups. Even 10 years later the cognitive performance of carotid stenosis patients was remarkably close to normal.
Equivalent of €5 billion of wood raw material is going to waste in Europe. The reason is that information regarding the raw material is not available throughout the system. An automatic traceability system makes it possible to use the raw material information throughout the forestry wood production system. The RFID-technology can achieve automatic traceability by enabling us to connect the physical world objects with their virtual counterparts. This traceability system needs to have a temporal data model to support tracking of the raw material and monitoring of the processes. In this paper, that data model for the traceability system of the forestry wood supply chain is presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
