    • The function of scent marking in beaver (Castor fiber) territorial defence 

      Rosell, Frank (Doctoral thesis, 2002)
      This thesis examines how scent marking in Eurasian beaver (Castor fiber) functions in territorial defence. Beavers usually deposit scent (castoreum and/or anal gland secretion (AGS)) onto small piles of mud and debris, and ...

    • Thermal Reactivity and Structure of Carbonized Binder Pitches 

      Madshus, Stian (Doktoravhandlinger ved NTNU, 1503-8181; 2005:83, Doctoral thesis, 2005)
      Pitches are used on a large scale in the manufacture of carbon anodes for the production of primary aluminium. The role of the pitch is to act as a binder between the petroleum coke grains. The structure of the carbonized ...

    • Ultrafiltration of Partially Degraded Starch Solution 

      Demessie, Berhanu (Dr.ingeniøravhandling, 0809-103X; 2002:87, Doctoral thesis, 2002)
      Desizing wastewater is largely responsible for the chemical oxygen demand (COD) load in the textile industry wastewater. A larger portion of COD comes from degraded starch in desizing wastewater. Removing the starch from ...

    • Understanding Selectivity in CO2 Hydrogenation to Methanol for MoP Nanoparticle Catalysts Using In Situ Techniques 

      Duyar, Melis S.; Gallo, Alessandro; Regli, Samuel K.; Snider, Jonathan L.; Singh, Joseph A.; Valle, Eduardo; McEnaney, Joshua; Bent, Stacey F.; Rønning, Magnus; Jaramillo, Thomas F (Peer reviewed; Journal article, 2021)
      Molybdenum phosphide (MoP) catalyzes the hydrogenation of CO, CO2 , and their mixtures to methanol, and it is investigated as a high-activity catalyst that overcomes deactivation issues (e.g., formate poisoning) faced by ...

    • Wettability of Silicon with Refractory Materials: A Review 

      Ciftja, Arjan (Research report, 2008)
      The wettability of ceramics by liquid metals is a key fac¬tor in many fields of high temperature materials science and engineering. The wetting behavior of liquid-silicon/refractory-materials system is especially important ...

    • Work Hardening and Mechanical Anisotropy of Aluminium Sheets and Profiles 

      Ryen, Øyvind (Dr. ingeniøravhandling, 0809-103X; 2003:105, Doctoral thesis, 2003)
      The processing of aluminium alloys from casting to end product is associated with a large number of metallurgical phenomena. In order to further improve and optimise process routes and alloys, a thorough understanding of ...
