OBJECTIVES: To demonstrate that novice dosimetry planners efficiently create clinically acceptable IMRT plans for head and neck cancer (HNC) patients using a commercially available multicriteria optimization (MCO) system. METHODS: Twenty HNC patients were enrolled in this in-silico comparative planning …

Due to their high adaptability and opportunistic predation behaviour feral cats have a great impact on worldwide bird biodiversity in particular on islands. However not much is known about their actual behaviour and time budget, as direct behavioural observations often are difficult regarding free-ranging …

Background: Computed tomography (CT) is one of the most used modalities for diagnostics in paediatric populations, which is a concern as it also delivers a high patient dose. Research has focused on developing computer algorithms that provide better image quality at lower dose. The iterative reconstruction …

Scanning tunneling microscopy is an important and enabling tool for condensed matter physics and surface science. The low temperature STM in Leiden (Prof. J. Van Ruitenbeek and Prof J. Aarts) is used for research in the field of atomic/molecular electronics and superconductivity. The current low temperature …

INTRODUCTION: Based on the windlass mechanism theory of Hicks, the medial longitudinal arch (MLA) flattens during weight bearing. Simultaneously, foot lengthening is expected. However, changes in foot length during gait and the influence of walking speed has not been investigated yet. METHODS: The foot …

Health care professionals responsible for patients with complex wounds need a particular level of expertise and education to ensure optimum wound care. However, uniform education for those working as wound care nurses is lacking. We aimed to reach consensus among experts from six European countries as …
