De noodzaak voor docentprofessionalisering is in dit tijdschrift al veelvuldig beschreven. Daarbij ligt het accent vaak op het individu. Maar juist collectieven zoals kenniskringen en lectorarten hebben een bijzonder vermogen om samen te leren. Het instellen van een kennisgemeenschap, zoals een Community …

In dit hoofdstuk wordt ingegaan op de toepassing van vraagpatronenonderzoek als middel om formele en informele ondersteuning te verbinden. Hierbij wordt nadrukkelijk niet alleen gekeken naar zorg, maar ook naar meer brede vormen van ondersteunende activiteiten waar burgers van profiteren en in participeren. …

One way to reduce the fuel consumption to payload ratio of heavy vehicle combinations is to reduce the empty trailer weight. This requires an understanding of the vehicle structure, assembly techniques and production process, and of special materials (e.g. high strength steel) with emphasis on strength …

The paper discusses the derivation of test data for three tractor-semitrailer combinations, to be used for strength and durability analysis of semi-trailers with the ultimate goal to reduce the semitrailer mass. Mathematical relationships have been used to transfer these data to representative loading …

In this paper the design and development of a new type of greenhouse with an integrated filter for reflecting near infrared radiation (NIR) and a solar energy delivery system is described. Especially the optical parts as the spectral selective film, the properties of the circular reflector and the efficiencies …

Ghrelin, a peptide predominantly produced by the stomach [1], appears to play an important role in the regulation of food intake. Intravenous infusion of ghrelin stimulates food intake and enhances appetite in humans [2]. In addition, plasma ghrelin concentrations rise gradually before a meal and decrease …

Optimization routines for battery, supercap and fuel cell stack in a fuel cell based propulsion system face two problems: the tendency to cycle beating and the necessity to maintain identical amounts of stored energy in battery and supercap at the start and end of the driving cycle used in the simulation. …
