L-alanine-induced germination in Bacillus licheniformis -the impact of native gerA sequences
(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. ... -
Laboratorietester av betain og andre baneavisingsmidler - smelteegenskaper og infiltrasjonsforsøk
(2021-03-25)Baneavisingsmidler benyttes for å sikre tilstrekkelig høy friksjon på rullebaner ved vinterforhold. Urea var vanlig å benytte som baneavisingsmiddel tidligere, men miljøskadelige effekter ved urea har gjort at de fleste ... -
Laboratorietester av personlig dosemåler
(2004)An electronic dosimeter, from MGP Instruments in France, capable of measuring gamma and neutron radiation has been tested for the Norwegian Defence Logistics Organisation / Land. Accuracy for dose response, energy response ... -
Laboratory analysis of CBRN-substances: Stakeholder networks as clue to higher CBRN resilience in Europe
(2016)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
(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 ... -
Laminar burning velocity of gases vented from failed Li-ion batteries
(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
(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 ... -
LAMU tracker – a tracker for sensors with Large Angular Measurement Uncertainty
(2007)LAMU (Large Angular Measurement Uncertainty) trackeren har blitt utviklet for sensorer med stor vinkel-usikkerhet, altså stor målestøy for vinkelmålingen. Mange HF (High Frequency) radarer er eksempler på slike sensorer. ... -
LandX20 Experiment Report – experiment for future land warfare capabilities with focus on increased situational awareness and unmanned systems
(2022-03-21)LandX20 was a collaborative experiment and demonstration where four research projects from the Norwegian Defence Research Establishment (FFI) participated. The goal of the experiment was two-fold. The first goal was to ... -
Langsiktig planlegging i Forsvaret - vitenskap i skjæringspunktet mellom politikk, byråkrati og kommandostyring
(2010)Rapporten handler om utviklingen av Forsvarets langtidsplanlegging fra tidlig på 1970-tallet og fram mot år 2000. Den beskriver den prinsipielle tilnærmingen, hvordan planleggingsmetodikken ble utviklet og hvilken rolle ... -
Langtrekkende presisjonsstyrte våpen : militærteoretiske betraktninger
(2004)The security political and military technological development has highlighted the employment of long-range precisionguided weapons. The use of these capabilities have increased own forces security and reduced collateral ... -
Langtrekkende presisjonsstyrte våpen : teknologiske betraktninger
(2004)This report discusses the technological development of long range precision weapons. The weapon systems discussed will normally have a CEP less than 30 meters and a range of more than 100 km (including the platform). The ... -
Large scale leakage of liquid hydrogen (LH2) – tests related to bunkering and maritime use of liquid hydrogen
(2021-01-13)Hydrogen is a promising energy carrier, which itself does not contribute to greenhouse gas emissions. Liquid hydrogen (LH2) is an efficient solution for transportation and storage of hydrogen. Especially for large vessels, ... -
Large scale MALDI-TOF MS based taxa identification to identify novel pigment producers in a marine bacterial culture collection
(2013)A challenge in the rational exploitation of microbial culture collections is to avoid superfluous testing of replicas. MALDI-TOF MS has been shown to be an efficient dereplication tool as it can be used to discriminate ... -
Large-eddy simulation of dense gas dispersion over a simplified urban area
(2017)Dispersion of neutral and dense gas over a simplified urban area, comprising four cubes, has been investigated by the means of large-eddy simulations (LES). The results have been compared to wind tunnel experiments and ... -
Large-eddy simulations of dense-gas dispersion within a high-Reynolds number turbulent boundary layer
(2017)Large-eddy simulations of flows over a backward-facing step with release of four different gases with increasing densities have been performed. The results have been analysed with particular emphasis on the part of the ... -
Laser beam propagation through turbulence and adaptive optics for beam delivery improvement
(2015-10-08)We report results from numerical simulations of laser beam propagation through atmospheric turbulence. In particular, we study the statistical variations of the fractional beam energy hitting inside an optical aperture ... -
Laserstråling gjennom turbulent atmosfære – Del 1 – stråling
(2022-04-25)Prosjektet "laservåpen og beskyttelse" innenfor forskningsprogrammet "luftvern, ubemannede luftsystemer og laser" går ut på å utvikle høyeffektlasere som mottiltak mot innkommende prosjektiler, droner og liknende. Siden ...
