      Krigsspill er en sentral aktivitet i operasjonsplanlegging for både å utvikle alternative handlemåter og utvikle plan basert på valgt handlemåte. Å gjennomføre krigsspill i et operativt miljø har stramme føringer i forhold ...
    • L-alanine-induced germination in Bacillus licheniformis -the impact of native gerA sequences 

      Madslien, Elisabeth Henie; Granum, Per Einar; Blatny, Janet Martha; Lindback, Toril (2014)
      Background L-alanine, acting through the GerA receptor, was recently found to be an efficient germinant in Bacillus licheniformis ATCC14580/DSM13. Results In this study, we show that several of 46 examined B. ...
    • Laboratory analysis of CBRN-substances: Stakeholder networks as clue to higher CBRN resilience in Europe

      The threat of terrorists using CBRN agents continues to pose a risk of mass casualties and severe disruption of societal functions in Europe. Standardisation of crisis management activities is one important step towards ...
    • Lack of behavioural responses of humpback whales (Megaptera novaeangliae) indicate limited effectiveness of sonar mitigation 

      Wensveen, Paul; Kvadsheim, Petter Helgevold; Lam, Frans-Peter A.; vonBenda-Beckmann, Sander; Sivle, Lise Doksæter; Visser, Fleur; Cure, Charlotte; Tyack, Peter L.; Miller, Patrick James O'Malley (2017)
      Exposure to underwater sound can cause permanent hearing loss and other physiological effects in marine animals. To reduce this risk, naval sonars are sometimes gradually increased in intensity at the start of transmission ...
    • LADEMU: a modular & continuous approach for generating labelled APT datasets from emulations 

      Gjerstad, Julie; Kadiric, Fikret; Grov, Gudmund; Kjellstadli, Espen Hammer; Asprusten, Markus Leira (2023-01-26)
      Development and evaluation of data-driven capabilities for both threat hunting and intrusion detection require high-quality and up-to-date datasets. The generation of such datasets poses multiple challenges, which has led ...
    • Laminar burning velocity of gases vented from failed Li-ion batteries 

      Henriksen, Mathias; Vaagsaether, K.; Lundberg, Joachim; Forseth, Sissel; Bjerketvedt, D. (2021-06-10)
      In the last decade, several fires and explosions caused by Li-ion batteries (LIBs) have been reported. This can be attributed to the thermal runaway and catastrophic failures of LIBs that release combustible gases, which ...
    • Laminar burning velocity of the dimethyl carbonate–air mixture formed by the Li-ion electrolyte solvent 

      Henriksen, Mathias; Vågsæther, Knut; Gaathaug, Andre Vagner; Lundberg, Joachim; Forseth, Sissel; Bjerketvedt, Dag (2020-08-21)
      If a Li-ion cell fails and the electrolyte leaks out into air, a flammable premixed gas cloud can be formed. The electrolyte combustion energy is 65–70% of the total energy content of the cell. The main objective of this ...
