      Rosell, Frank; Rosef, Olav; Parker, Howard (Journal article; Peer reviewed, 2001)
      The presence of pathogenic bacteria and parasites in drinking water is a well-known cause of human disease outbreaks. There is however, a lack of knowledge of the contamination routes to water. In Norway, the supply of ...
    • Parturition dates for Eurasian beavers Castor fiber: when should spring hunting cease? 

      Parker, Howard; Rosell, Frank (Journal article; Peer reviewed, 2001)
      Hunting Eurasian beaver Castor fiber with firearms during late spring is the dominating harvest form in Norway but may violate the Norwegian wildlife management principle of not hunting during the breeding season. In ...
    • Odorant source used in Eurasian beaver territory marking 

      Rosell, Frank; Sundsdal, Lars Jøran (Journal article; Peer reviewed, 2001)
      Mammals use urine, feces, or the secretion of specialized skin glands to mark their territories. These sources can carry different information and, thus, have different functions. Presently it is not known if beavers (Castor ...

    • Koppermangel hos oppdrettshjort 

      Rosef, Olav; Fimreite, Norvald; Egeland, Bjørn (Journal article; Peer reviewed, 2001)
      Raising red deer in enclosures for meat production is a relatively new practice in Norway and is based on national stocks (Cervus elaphus atlanticus). Presently only 400 - 500 hinds are reared in enclosures by 25 ...
    • Effectiveness of predator odors as gray squirrel repellents 

      Rosell, Frank (Journal article; Peer reviewed, 2001)
      The ability of gray squirrels (Sciurus carolinensis) to discriminate between different predator odors and the use of predator odors to deter gray squirrels from foraging on plants have not been previously investigated. To ...
    • On the use of parameterization in the implementation of geometry 

      Kjenstad, Kjell (Conference report, 2001)
      Parameterization of object-classes is an attractive approach during implementation of an object-oriented software system. This text discusses different cases of possible parameterization in the implementation of geometry ...
    • Modified Smith-predictor multirate control utilizing secondary process measurements 

      Ergon, Rolf (Conference report, 2001)
      The Smith-predictor is a well-known control structure for industrial time delay systems, where the basic idea is to estimate the nondelayed process output by use of a process model, and to use this estimate in an inner ...
    • Assessment of sulphur emission at Norcem's cement kiln by use of 35S-tracer 

      Eriksen, Dag Øistein; Tokheim, Lars-André; Eriksen, T.A.; Martini, V.; Qvenild, Carsten (Conference report, 2001)
      Although sulphur is not a major reacting species in making cement clinker, it is introduced as a pollutant in both the energy carrier (oil, coke, coal, household waste) and in the reactants (chalk, silica). Due to the ...
    • Energy recovery from wastes : experience with solid alternative fuels combustion in a precalciner cement kiln 

      Tokheim, Lars-André; Gautestad, Tor; Axelsen, Ernst Petter; Bjerketvedt, Dag (Conference report, 2001)
      Today virtually all cement clinker burning processes take place in rotary kilns. A mixture of calcareous and argilaceous materials is heated to a temperature of about 1450 °C. In this process decarbonation followed by ...
    • Vitenskapsteoretiske posisjoner innen norsk friluftslivsforskning 

      Odden, Alf (Others, 2001)
      Friluftsliv som eget forskningsfelt har et relativt begrenset omfang, men har nær tilknytning til andre og større forskningsfelt som fritid, turisme, kultur og naturforvaltning. Sentrale tema for den norske forskningen har ...
    • Quantification of biofilm accumulation by an optical approach 

      Bakke, Rune; Kalvenes, Sigmund; Kommedal, Roald (Journal article; Peer reviewed, 2001-02)
      Methods for non-invasive, in situ, measurements of biofilm optical density and biofilm optical thickness were evaluated based on Pseudomonas aeruginosa experiments. Biofilm optical density, measured as intensity reduction ...

      In Norway, Sweden and Finland moose Alces alces hunting teams are often employed to survey occupied beaver (Castor fiber and C. canadensis) lodges while hunting. Results may be used to estimate population density or trend, ...
    • PLS score-loading correspondence and a bi-orthogonal factorization 

      Ergon, Rolf (Journal article; Peer reviewed, 2002)
