De BodyMetrix (BM) is een portabel, relatief nieuw en goedkoop echografisch apparaat voor het meten van lichaamssamenstelling. In deze systematische review wordt de betrouwbaarheid van BM en de validiteit ten opzichte van dual-energy X-ray absorptiometrie (DXA) en plethysmografie met luchtverplaatsing …

This thesis discusses the progress made on the development of superficial hyperthermia treatment planning. For superficial hyperthermia treatment, contact flexible microstrip applicators (CFMA) are used. These applicators are bent along the body curvature of the patient. A software tool, written in …

To increase the yield and quality of aquaculture feed, the effects of N and P concentrations on biomass productivity and cell composition were examined in the marine diatom Skeletonema costatum. Batch-cultured microalgae in Walne’s medium with 3.5 ± 0.5 mmol L-1 N-NO3- and 0.30 ± 0.05 mmol L-1 P-PO43- …

In the Province of Zeeland, ragworms (Alitta virens) are farmed on large scale in open rectangular (flow through systems) ponds. In April these ponds are stocked with ragworm larvae from a hatchery. The juveniles bury themselves in the sediment layer in the pond and are fed with feed pellets. Dependent …

For research to the composition of oxylipids in human plasma and tissue it was necessary to have an analytical method that can measure these lipids on very low concentrations. In this bachelor thesis the development of a LC-MS method will be discussed.

In this study, various extraction methods were compared based on their ability to extract both free amino acids, and free 5’-monophosphate nucleotides from the seaweed Saccharina latissima. Based on the results, extraction at room temperature with Milli-Q over 24 hours was chosen as the method of choice, …

Daily life is greatly influenced by fossil fuels. New technological inventions and the reduction of the ice coverage due to climate change makes it possible for humans to be present and undertake activities, such as gathering oil in previously inaccessible areas like the North Pole (Sagerup, Nahrgang, …

This research was conducted on behalf of the education of ‘Management in Healthcare’ at the University of Applied Sciences Leiden. The study of ‘Management in Healthcare’ is an dual education that is intended for working healthcare professionals to a middle manager position in the healthcare and welfare …

Introduction: Body composition and body circumferences are tools for health professionals to predict health risks and to evaluate a patient’s treatment. The BODPOD® is a validated device to determine body composition, but it is expensive and therefore not accessible for a lot of health professionals. …

Gas-phase diffusion is a widespread process in nature, for example diffusion of pollutants in the atmosphere. A special case of diffusion is the so-called Knudsen diffusion where a gas diffuses in the molecular flow regime. The theory for Knudsen diffusion is well-known therefore, diffusion experiments …
