Materials with semiconducting properties are present in every microelectronic device and form the backbone of our information society. Commonly used inorganic semiconductors are poorly modular and their production is expensive and energetically demanding. Moreover, the use of metals and critical raw …

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 …

The customers of Inspectorate ship gasoline to Asia. Due to the limitations of the ships and costs of the journey it is preferred to concentrate the gasoline. The concentrated gasoline can be blended with other “cheaper” forms of gasoline to make the required gasoline. Because of the concentrated form …

The goal of this graduation paper is a literature review on the effect of light and nitrogen availability on the pigment composition, photosynthesis and growth of different phytoplankton groups.

Het doel van het onderzoek is om verbeterpunten aan te merken met betrekking tot het optimaliseren van projectbeheersing tussen OCI Nitrogen B.V. en Sitech Services B.V. Hier is de volgende centrale vraagstelling uit voortgekomen: Hoe kan optimale beheersing worden bereikt over de door OCI Nitrogen B.V. …

This project helps to reach the end goal of doing long distance measurements. Long distance measurements depends on the refractive index of air. The refractive index depends on temperature, pressure, humidity and gas mixture. The biggest uncertainty of calculating the refractive index is the temperature, …

De waterkwaliteit van het oppervlaktewater in het beheergebied van Waterschap Peel en Maasvallei wordt sterk beïnvloed door de huidige landbouw, nalevering uit de bodem en water dat over de landsgrenzen binnenkomt. De verwachting is dat de nalevering uit de bodem nog tientallen jaren de waterkwaliteit …

The Pierre Auger group is studying ultra-high energy cosmic rays. Cosmic rays are charged particles which permanently hit and penetrate the atmosphere of the Earth. They will at a certain moment collide with nuclei in the atmosphere, like nitrogen. The results of such an interaction are new particles, …

A high resolution infrared spectrum of species formed in a nitrogen-hydrogen plasma expansion was recorded. A cavity ring down detection scheme was used to record a rotationally resolved spectrum in the region from 3300 cm-1 to 3380 cm-1. Using the relative intensities and line positions it was determined …

Hoge stikstofdepositie leidt in voedselarme ecosystemen nog steeds tot een overschrijding van de maximum tolerantiegrens. De overmatige stikstofdepositie werkt niet alleen in op planten(gemeenschappen) en herbivoren maar de grotere hoeveelheid beschikbare stikstof werkt door op het gehele ecosysteem. …
