The use of transactions in flexible manufacturing systems is expected to result in a number of advantages like increased software reliability and minimized restart times in the case of system or machine failures. Here, an architecture of a system for handling processes on machine tools under transactional protection is briefly presented. Special attention must be drawn to the component which de...

Five years have passed since the publication of a landmark report by the National Association of State Mental Health Program Directors, calling attention to the high morbidity and mortality associated with psychiatric disabilities (Parks, Svendsen, Singer, & Foti, 2006). On average, people with serious mental illnesses die 25 years earlier than the general population, and 60% of these deaths ar...

tivity Questionnaire (IPAQ). The study population could be matched with respect to physical activity using the IPAQ. The IPAQ version that we use in our studies is the short last 7-day recall questionnaire. This version consists of seven questions assessing the frequency and duration of participation in vigorous, moderate intensity and walking activity as well as the time spent sitting during a...

Recovery from exercise is integral to the physical training process. There is a perception among older athletes that aging negatively affects the recovery process. Plausible arguments for an impaired recovery with aging are a greater susceptibility of older muscle to exercise-induced skeletal-muscle damage and a slower repair and adaptation response. Differences in the physical activity level o...

BACKGROUND When it comes to prevalidation, it is assumed that a higher preoperative level of physical activity leads to better postoperative recovery. However current literature is inconclusive about the effect of prevalidation on functional recovery of patients with primary osteoarthritis (OA) who underwent a THA or TKA. Therefore the aim of this study is to analyse one of the major assumption...
