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 …

Vraagstelling: Welke maximale laboratoriumtest meet het best de aerobe capaciteit bij rolstoelafhankelijke kinderen en adolescenten van zes tot 18 jaar met Spina Bifida: de rollerbank test of de armergometer test? Methode: 11 rolstoelafhankelijke kinderen en adolescenten (acht jongens, drie meisjes, …

In welke mate worden (proef)dieren ingezet tijdens biologielessen in het grijze voortgezet onderwijs en wat zijn de beweegredenen en kennis van de docenten met betrekking tot het inzetten van deze dieren? Wat zijn de relaties tussen het (proef)diergebruik, het niveau en de fase, de kennis en de andere …

A laboratory test setup is built to transfer and actively stabilize an ultrastable signal, obtained from a laser with sub-Hz linewidth, trough a 5 km long fiber link. The fiber noise is measured and compensated via a feedback loop acting on an AOM that can change the frequency (and therefore the phase) …

Laboratory study using a repeated measures design. The aim of this study was to determine if ankle proprioception is targeted in exercises on unstable surfaces. Lateral ankle sprain (LAS) has recurrence rates over 70%, which are believed to be due to a reduced accuracy of proprioceptive signals from …

Laboratory research was done on flat glass substrates to study the effect that brine salinity has on adhesion mechanisms between oil and clay particles. This is done by evaporating a small clay suspension droplet (6 ul) on a glass slide that leaves a thin layer of clay upon which oil can be attached. …

Much research effort is invested in developing enzymatic treatments of textiles by focusing on the performance of enzymes at the laboratory scale. Despite all of this work, upgrading these developments from the laboratory scale to an industrial scale has not been very successful.Nowadays,companies are …

Identification of the requirements for a handheld computer in aviation maintenance by Goossen, Kuyper and de Boer. In many MRO departments problems are encountered with the use of manuals, task lists and ‘black books’ on paper. These problems are a critical factor for aviation safety and productivity …

This study investigated the effect of work pace on workload, motor variability and fatigue during light assembly work. Upper extremity kinematics and electromyography (EMG) were obtained on a cycle-to-cycle basis for eight participants during two conditions, corresponding to "normal" and "high" work …
