The main objectives of this review were to: (1) review different methods/techniques to assess gaseous N-losses from manure (2) review N-gaps, attributed to dinitrogen loss as the difference between directly measured N compounds summed as total N loss and indirectly measured N loss through a mass balance …

In de afgelopen zes jaar is er veel aandacht besteed aan de ontwikkeling van meetstandaarden voor het siloxaangehalte in biomethaan en opgewaardeerde biogas. Biogas is wereldwijd van toenemend belang als energiedrager. Het vormt een milieuvriendelijk alternatief voor aardgas en draagt bij tot de vermindering …

The natural gas/diesel dual-fuel engine is an interesting technique to reduce greenhouse gas emission. A limitation of this concept is the emission of un-combusted methane. In this study we analyzed the influence of PFI gas-injection timing on cylinder to cylinder gas-distribution, and the resulting …

A Quad Focus GridPix Gaseous Tracking Detector is under construction, to allow calibration and test beam measurements to validate the working principles of the (quad) GridPix detectors while using a focused electric field. The development is well on its way: both measurements should be able to be conducted …
