Angular Dependence of the Ion-Induced Secondary Electron Emission for He+ and Ga+ Beams

In recent years, novel ion sources have been designed and developed that have enabled focused ion beam machines to go beyond their use as nano-fabrication tools. Secondary electrons are usually taken to form images, for their yield is high and strongly dependent on the surface characteristics, in terms of chemical composition and topography. In...

DELTA 2000: Inventarisatie huidige situatie Deltawateren

Het Zuidelijke Deltagebied is een uniek gebied waar water centraal staat. De karakteristieke eigenschappen van de watersystemen vormen het visitekaartje van de regio. Dit is een visitekaartje ingekleurd met zowel internationaal erkende natuurwaarden als met economische belangrijke sectoren als zeevaart en schelpdiervisserij en recreatie. Water...

Reconstruction of sea level history during the middle Holocene at the Leschenault Peninsula, Westem Australia

At the Leschenault Peninsula, a reconstructed sea level curve showed a maximum sea level of 3 to 4 m above the present mean sea level during the middle Holocene. This did not agree with other sea level curves along the Western Australian coast, which were lower at that period. It was assumed that local tectonic uplift could be a reason for this...
