Refining and Recycling of Silicon: A Review
(Research report, 2008)Silicon has a very broad spectrum of usage nowadays and it lies at the heart of much modern technology. It is the most abundant element in the earth’s crust after oxygen. Indeed, it’s use ranges from such bulk commodities ... -
Rheology and Reactivity of Cementitious Binders with Plasticizers
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:189, Doctoral thesis, 2005)The rheological behaviour of cementitious pastes has been studied by various means. Six different cements have been studied in main parts of the work and all of them have been characterized according to the Rietveld method ... -
The role of indirect interspecific effects in the stochastic dynamics of a simple trophic system
(Journal article; Peer reviewed, 2024)Indirect interspecific effects (IIEs) occur when one species affects another through a third intermediary species. Understanding the role of IIEs in population dynamics is key for predicting community-level impacts of ... -
Sea Ice Studies in the Northern Sea Route by use of Synthetic Aperture Radar
(Dr. ingeniøravhandling, 0809-103X; 2002:22, Doctoral thesis, 2000)The main objective of this thesis is to contribute to the understanding of sea ice processes in the Northern Sea Route, mainly with use of remote sensing data from Synthetic Aperture Radar (SAR). Multivariate data analysis ... -
Sorption-enhanced steam methane reforming in fluidized bed reactors
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:116, Doctoral thesis, 2006)Hydrogen is considered to be an important potential energy carrier; however, its advantages are unlikely to be realized unless efficient means can be found to produce it without generation of CO2. Sorption-enhanced steam ... -
Steam explosions during granulation of Si-rich alloys.: Effect of Al- and Ca-additions
(Dr.ingeniøravhandling, 0809-103X; 2002:43, Doctoral thesis, 2002)Steam explosions are possible during granulation of Si and FeSi75. These explosions are a great hazard, and must be avoided. Norwegian ferroalloy producers have initiated a research program to learn more about such violent ... -
