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 …

When treating cancer by radiation therapy it is always the goal to irradiate the tumour as much as possible and to spare the healthy tissue around it. For this a new type of radiation therapy called Volumetric Modulated ARC Therapy (VMAT) has been developed. During VMAT treatment the radiation machine …

Service design is literally the design of services. Service designers improve existing services or design completely new ones. Nothing new so far. Services have been around for centuries, and every service was conceived and designed by someone. However, service design takes a different angle; a different …

The ambition to host mega sports events is (or can be) perfectly justifiable with various arguments. The most persistently used argument is the supposed financial or direct economic gain for the host economy, of which the compelling body of evidence is discouraging. This implies that the justification …

In the medical community, X-rays are an important tool in imaging the human body. In principle X-ray images are 2 dimensional images. By measuring such X-ray images at multiple angles, one can construct the 3 dimensional inner structure of the sample. This 3 dimensional structure is created by applying …

This thesis describes how the abundance of CO2 a ects the porosity of H2O:CO2 ice mixtures deposited at di erent growth temperatures ranging from 30 - 70 K. The mixing ratios of the used ice samples H2O:CO2 = 10:1, 4:1 and 2:1 are of astrophysical relevance. Laser optical interference is used to monitor …

A new gravitation wave observatory is being built in Japan. This facility is a big Michelson interferometer where the mirrors and sensors will be made cryogenic down to 4 K. The problem is that: the heat cannot be transported out of the mirror by its surroundings because the whole system is in an ultra-high …

Study Type – Aetiology (individual cohort) Level of Evidence 2b What's known on the subject? and What does the study add? Recent studies have already shown associations between generalized joint hypermobility (GJH) and voiding and defecation dysfunction and/or slow transit constipation. Changes in extracellular …

In this article we investigate the change in wetting behavior of inkjet printed materials on either hydrophilic or hydrophobic plasma treated patterns, to determine the minimum obtainable track width using selective patterned μPlasma printing. For Hexamethyl-Disiloxane (HMDSO)/N2 plasma, a decrease in …

Inkjet printing is a rapidly growing technology for depositing functional materials in the production of organic electronics. Challenges lie among others in the printing of high resolution patterns with high aspect ratio of functional materials to obtain the needed functionality like e.g. conductivity. …
