This project helps to reach the end goal of doing long distance measurements. Long distance measurements depends on the refractive index of air. The refractive index depends on temperature, pressure, humidity and gas mixture. The biggest uncertainty of calculating the refractive index is the temperature, …

This report describes the work that has been done on the water calorimeter project at VSL. The calorimeter determines the absorbed-dose-to water Dw in gray, by measuring the radiation induced temperature change. The temperature of the water will change due to irradiation of a beam ionizing radiation. …

In this study we assessed which is the most appropriate method of detecting stress to study the effect of Jacobson’s progressive relaxation exercises in patients with stress problems. In the study 7 patients are requested to fill in 3 different scales to quantify their stress before and after the exercises. …

Introduction: In recent years some researchers investigated the effect of lumbar muscle fatigue on postural control in quiet standing and sitting. The goal of this study was to transfer the question if changes in postural control are visible after fatigue into a functional, dynamic setting. Research …

PURPOSE: Advanced radiotherapy treatments require appropriate quality assurance (QA) to verify 3D dose distributions. Moreover, increase in patient numbers demand efficient QA-methods. In this study, a time efficient method that combines model-based QA and measurement-based QA was developed; i.e., the …

Background: Endothelial dysfunction is a marker of early stages of atherosclerosis and in general of cardiovascular disease. Assessing the endothelium can be achieved non-invasively, using the flow-mediated dilatation technique. Method: For the experiment 21 patients with an inactive cardiovascular …

BACKGROUND: Understanding of the consequences of a neuromuscular disease (NMD) can improve when a valid sample of disease-specific categories based on the International Classification of Functioning, Disabilities, and Health (ICF) is available. OBJECTIVE: To examine the content validity of the initial …

In research methodology, epistemology is concerned with the question how humans generate knowledge. In facility management (FM) research, for instance, it deals with the evaluation criteria such as validity and reliability by which researchers discriminate good knowledge from bad. The objective of this …

Background: Nasal breathing is a commonly used technique among runners. However, the scientific research available on the topic is limited. The aim of this study was to investigate the effect of nasal breathing on runners' posture, perceived exertion and the effect of practice. Method: The participants, …

PURPOSE: The purpose of this study was to gain insight into how low back pain (LBP) patients conceptualize the construct of expectations regarding treatment. METHODS: This study was nested within a mixed-method randomized clinical trial comparing three primary care interventions for LBP. A total of 77 …
