The volatile matter (VM) content and composition of birch biochars produced at 320 °C under elevated pressure (0.1–11 MPa) and constant pressure or constant volume reactor conditions were characterized by thermogravimetry/mass spectrometry (TG/MS) and pyrolysis–gas chromatography/mass spectrometry...
A significant surface wettability transition from hydrophobicity to hydrophilicity after long-term operation is observed in graphite bipolar plates of a proton exchange membrane fuel cell (PEMFC). Extensive in-situ electrochemical characterization was performed to investigate the impact of bipolar...
This paper summarizes experiments that were carried out on insulating ceramic substrates and a needle-plane arrangement with the purpose to characterize the inception of partial discharges (PD) in the insulation of high-voltage semiconductors. PD measurement results obtained on substrates are...
This report summarizes the findings from a price experiment survey on the willingness to pay (WTP) for salmon produced using new production systems in salmon farming in three countries (Norway, Canada and Scotland). This includes land-based, floating closed containment cages and offshore production...
Denne rapporten har som formål å gi en kortfattet introduksjon samt være en håndbok og oversikt over noen utvalgte målestrategier og metoder i vannkraftverk. Den omhandler tema som standarder, datamengde, båndbredde, oppløsning på data, sampling intervall, tidsnøyaktighet, nytteverdi og...
Denne rapporten har som formål å gi en kortfattet introduksjon samt være en håndbok og oversikt over noen utvalgte målestrategier og metoder i vannkraftverk. Den omhandler ulike sensorer for bruk i vannkraftverk og er tett koblet med rapport del II som omhandler målemetodikk. Håndboken har vært...
Wet-design AC subsea power cables are currently rated up to a maximum voltage of 72.5 kV. These high voltage (HV) cables are cost-effective alternatives to subsea cables kept dry by a protective lead sheath and exhibit superior properties for dynamic applications. However, several vented water trees...
