Hvordan kan vi ruste Norge mot fremtidens ekstremvær? Den nasjonale konferansen for klimatilpasning samlet 300 aktører på tvers av sektorer og fagfelt for å finne løsninger....

Gas fermentation using acetogens via the Wood–Ljungdahl pathway offers a sustainable route for converting CO₂ and hydrogen into valuable chemicals. This study presents a comprehensive techno-economic analysis of a 50,000 t/a acetic acid (AcOH) production plant based on gas fermentation. Three...

This study examines the uni-axial unconfined compressive strength of stabilized clay mixed with different types of binders [1]. The binders tested were cement kiln dust (CKD), lime (CaO) and ordinary Portland cement (OPC) exclusively or in different combinations. Samples were hardened for...

We consider the Lame form of the elasticity system and demonstrate the famous paradox, which can be obtained by the limit passage in the polygonal plates with very small sides as the length of sides goes to zero. The phenomenon is that boundary conditions in the original problem and the limit...

The design load levels of Arctic offshore structures are likely to be determined by first year sea ice ridges and rubble field. Better understanding of ice rubble will help us to determine this design load level accurate enough. From a set of punch shear tests conducted by Heinonen, J. (2004) in the...

The presentation focus on the U-value of a Con-Form concrete wall, and how it is influenced by varying some of the structural and material properties. Specifically, the influence of the following parameters are analyzed....

Three types of carbon nanotubes(CNT) have been investigated regarding their suitability as spectrally selective solar thermal absorbers.The CNT coatings were electrophoretically deposited on aluminum substrates using kinetically stable CNT aqueous suspensions, of which two CNT aqueous suspensions (N...

Ice loads are core design criteria for hydropower dams in northern regions. They are responsible for a significant proportion of the design load of small dams that are typically used in Norway. In spite of their importance, the magnitude and regional variability of ice loads are still poorly...
