We have investigated the photoionization and photodissociation of free coronene cations C24H12+ upon soft X-ray photoabsorption in the carbon K-edge region by means of a time-of-flight mass spectrometry approach. Core excitation into an unoccupied molecular orbital (below threshold) and core ionization …

Background: Activity trackers can potentially stimulate users to increase their physical activity behavior. The aim of this study was to examine the reliability and validity of ten consumer activity trackers for measuring step count in both laboratory and free-living conditions. Method: Healthy adult …

BIM for improving energy efficiency in historic buildings.Workshop voor professionals betrokken bij het herontwikkelen van duurzame monumenten in de praktijk. Centraal stond de discussie over de toepassing van BIM bij complexe erfgoedprojecten.

BACKGROUND: Long-term survival of renal transplant recipients (RTR) has not improved over the past 20 yr. The question rises to what extent lifestyle factors play a role in post-transplant weight gain and its associated risks after transplantation. METHODS: Twenty-six RTR were measured for body weight, …

BACKGROUND: Ambulatory children with Spina Bifida (SB) often show a decline in physical activity leading to deconditioning and functional decline. Therefore, assessment and promotion of physical activity is important. Because energy expenditure during activities is higher in these children, the use of …

Fuel cell hybrid vehicles are believed to provide a solution to cut down emissions in the long term. They provide local zero-emission propulsion and when the hydrogen as fuel is derived from renewable energy sources, fuel cell hybrids enable well-to-wheel zero-emission transportation, …

An existing fuel cell hybrid distribution truck, built for demonstration purposes, is used as a case study to investigate the effect of stack (kW) and battery (kW, kWh) sizes on the hydrogen consumption of the vehicle. Three driving cycles, the NEDC for Low Power vehicles, CSC and JE05 cycle, define …

Vanuit de uitdaging het gebied te ontwikkelen tot een innovatief landbouwgebied met duurzame energie‐, water‐ en klimaathuishouding is het idee onderzocht de functie wateropslag te combineren met de productie van duurzame energie. Het doel van het onderzoek is vast te stellen of het financieel en technisch …

Het landgoed Verwolde overweegt de aanschaf van een biomassa installatie. Daarbij is van belang te weten hoeveel biomassa uit houtoogst en landschapsonderhoud vrij zullen komen. In de meeste situaties zal worden gerekend met een ruwe omrekenfactor. In dit onderzoek is getracht een verfijning te maken …

Nuclear fusion is seen as one of the future technologies for roducing electrical power. In a hot and con ned plasma deuterium and tritium will melt together and form a helium nucleus and a neutron. This process produces a total of 17.6 MeV energy. In the plasma instabilities occur. Suppression of these …
