Lithological control on scour hole formation in the Rhine-Meuse Estuary

River deltas commonly have a heterogeneous substratum of alternating peat, clay and sand deposits. This has important consequences for the river bed development and in particular for scour hole formation. When the substratum consists of an erosion resistant top layer, erosion is retarded. Upon breaking through a resistant top layer and...

Dutch national scientific research program on land subsidence: Living on soft soils – subsidence and society

In the Netherlands land subsidence is a continuously ongoing process. Consequently, an increasing number of people and economic assets are exposed to subsidence, damage costs are soaring, and flood risk and greenhouse gas emissions are increasing. In some areas tipping points have already been reached, where current land-use can no longer be...

Preservation of Last Interglacial and Holocene transgressive systems tracts in the Netherlands and its applicability as a North Sea Basin reservoir analogue

Understanding of complex sedimentary records formed by transgressive systems is critical for hydrocarbon exploration and exploitation, and carbon capture and storage. This paper discusses the facies proportions and preservation of the Last Interglacial and Holocene transgressive systems tracts in the Netherlands and their applicability as a...

Understanding and managing the morphology of Rhine Delta branches incising into sand-clay deposits

In the Rhine-Meuse delta in the south-western part of the Netherlands, the morphology of the river branches is highly dependent on the erodibility of the subsoil. Erosion processes that were initiated after closure of the Haringvliet estuary branch by a dam (in 1970), caused a strong incision of several connecting branches. Due to the geological...

Historische rivierkundige parameters: Maas, Merwede, Hollandsch Diep en Haringvliet

Dit werkdocument is een achtergronddocument bij de studie naar de morfologische potenties van het rivierengebied, zoals die in opdracht van het hoofdkantoor (WONS-inrichting, vanaf 2003 Stuurboord) wordt uitgevoerd. In het eindrapport van deze studie: Kansrijkdom voor rivierecotopen van historisch en geomorfologisch perspectief (Middelkoop et al...

Methanol oxidation in a spontaneous mutant of Thiosphaera pantotropha with a methanol-positive phenotype is catalysed by a dye-linked ethanol dehydrogenase

Isolation, Sequencing and Mutational Analysis of a Gene-Cluster Involved in Nitrite Reduction in Paracoccus-Denitrificans

A theoretical evaluation of growth yields of yeasts

Growth yields of Saccharomyces cerevisiae and Candida utilis in carbon-limited chemostat cultures were evaluated. The yields on ethanol and acetate were much lower in S. cerevisiae, in line with earlier reports that site I phosphorylation is absent in this yeast. However, during aerobic growth on glucose both organisms had the same cell yield....
