BACKGROUND: Most patients with cystic fibrosis (CF) suffer from pancreatic insufficiency, leading to fat malabsorption, malnutrition and abdominal discomfort. Until recently, no specific tool was available for assessing gastro-intestinal related quality of life (GI QOL) in patients with CF. As the Horizon2020 project MyCyFAPP aims to improve GI QOL by using a newly designed mobile application, a sensitive and reliable outcome measure was needed. ...

BACKGROUND:Pediatric Quality of Life Inventory (PedsQL) is a measure to assess health-related quality of life (HRQoL) in children and adolescents. It is formed by 23 items adapted to children age and includes a parent proxy report version. With four multidimensional subscales and three summary scores, it measures health as defined by WHO. The concepts measured by this instrument are 'physical functioning' (8 items), 'emotional functioning' (5 ...

Bicycles with electrically powered pedal assistance (PA) show great potential as ecological alternatives for engine-based vehicles. There is plenty of research available about the influence of various bicycle parameters on cycling technique. Though, to the best of the authors' knowledge, there is none about the influence of PA. In this study, a recreational bicycle is equipped with PA and unique instrumentation to measure the user-induced loads ...

Bicycle commuting has gained popularity as an eco-friendly and healthy alternative to driving, offering benefits like improved fitness and cost savings. Historically, it was commonly associated with short urban journeys, typically within city centers covering distances of up to 5 kilometers. However, the feasibility of using bicycles for longer commutes, ranging from 10 to 40 kilometers, was limited. The landscape changed with the introduction ...

A Pedal Series Hybrid Drivetrain (PSHD) uses an electrical power transmission rather than a chain, belt, or shaft. It creates exciting opportunities for the vehicle’s design, but pedalling does not always feel comfortable. This study evaluates the pedalling comfort of a custom PSHD in an electric cargo tricycle. In this PSHD, pedal-driven generator converts human mechanical power to electrical power ...

In this study, we evaluated the effects of a novel pedal design, characterized by a downward and forward shift of the cleat fixing platform relative to the pedal axle, on maximal power output and mechanical efficiency in 22 well-trained cyclists. Maximal power output was measured during a series of short (5-s) intermittent sprints on an isokinetic cycle ergometer at cadences from 40 to 120 rev (.) min(-1). Mechanical efficiency was evaluated ...

Two bromomethylated azobenzene derivatives were characterized by X-ray crystallography at 100 K after fast cooling, and showed disorder of the central N-atoms. The structures were re-determined over a range of temperatures, providing evidence for dynamic disorder due to pedal motion of the central N[double bond, length as m-dash]N bond. Using van't Hoff plots, thermodynamic parameters for the pedal motion were determined. Computationally very ...
