UPLC-MS is a commonly used technique to first separate complex samples and subsequently quantify molecules of interest. Herein we describe the use of UPLC-MS using an amide stationary phase to quantify non-derivatized amino acids extracted from fingerprints. As detector either a triple-quadrupole MS/MS …

In de praktijk komt het voor dat de standaard veldgrootte onnodig wordt vergroot, zonder dat MBB’ers zich hier bewust van zijn. Hierdoor ontvangt de patiënt onnodig meer dosis en wordt het ALARA-principe niet nageleefd. De veldgrootte wordt onnodig aangepast bij laterale knie opnames. Hierdoor ontstaat …

Autonomous driving in public roads requires precise localization within the range of few centimeters. Even the best localization systems based on GNSS cannot always reach this level of precision, especially in an urban environment, where the signal is disturbed by surrounding buildings and artifacts. …

Multiple scientific and industrial applications such as telecommunication and quantum cryptography causing a rise in the development of the superconducting nanowire single photons detectors (SNSPD). In the last decade, the characteristics of the detectors improved but run against the problem that the …

Autonomous driving in public roads requires precise localization within the range of few centimeters. Even the best current precise localization system based on the Global Navigation Satellite System (GNSS) can not always reach this level of precision, especially in an urban environment, where the signal …

Only nine percent of rolling element bearings operate long enough to achieve their design life. The leading cause of failure, by 43 percent, is improper lubrication. This includes over lubrication or a lack of lubrication. This will lead to unexpected failure of the bearings, which could result in a …

AkzoNobel is a multinational sustainable company which makes paints, coatings and special chemicals. Hexahydrophthalic anhydride, phthalic anhydride and trimellitic anhydride are dangerous chemicals, because they can cause irritations and allergic reactions. These chemicals are often used in paint and …

Het Mauritshuis doet momenteel onderzoek naar de pigmenten en laagopbouw in verfmonsters uit kunst van Jan Steen en Giovanni Antonio Pellegrini. Hierbij wordt met Shell Nederland BV samengewerkt onder het Partners in Science project. Een onderdeel van dit project is een onderzoek naar het blauwe pigment …

In pre-treatment dose verification, low resolution detector systems are unable to identify shifts of individual leafs of high resolution multi leaf collimator (MLC) systems from detected changes in the dose deposition. The goal of this study was to introduce an alternative approach (the shutter technique) …

Cyanobacteriochromen (CBCR) zijn fytochroom-gerelateerde fotoreceptor eiwitten, die van eiwitstructuur veranderen wanneer deze belicht worden met bepaalde kleuren licht. Tijdens deze foto-conversie transformeren de CBCRs van de ene stabiele staat naar de andere, via het doorlopen van verschillende tussenproducten. …
