Low-energy electron ionization mass spectrometer for efficient detection of low mass species
(Journal article; Peer reviewed, 2021)The design of a high-efficiency mass spectrometer is described, aimed at residual gas detection of low mass species using low-energy electron impact, with particular applications in helium atom microscopy and atomic or ... -
Low-energy probes of no-scale SU(5) super-GUTs
(Journal article; Peer reviewed, 2021)We explore the possible values of the \(\mu \rightarrow e \gamma \) branching ratio, \(\text {BR}(\mu \rightarrow e\gamma )\), and the electron dipole moment (eEDM), \(d_e\), in no-scale SU(5) super-GUT models with the ... -
Low-energy surface vibration measurements on the alpha-quartz (0001) surface
(Master thesis, 2011)Despite the enormous range of usages, only little is known about the dynamic and structural properties of quartz (SiO2) surfaces on the atomic scale. The main reason for this is probably that quartz is an insulator, with ... -
Low-level jet height’s impact on wind turbine loads: A case study
(Master thesis, 2023-06-01)Over the years, wind turbines have been steadily increasing in size, with newer models boasting larger dimensions. For instance, the diameter of an installed prototype offshore wind turbine in late 2022 was over 200 m, ... -
Low-Rank Binary Matrix Approximation in Column-Sum Norm
(Journal article; Peer reviewed, 2020)We consider 𝓁₁-Rank-r Approximation over {GF}(2), where for a binary m× n matrix 𝐀 and a positive integer constant r, one seeks a binary matrix 𝐁 of rank at most r, minimizing the column-sum norm ‖ 𝐀 -𝐁‖₁. We show ... -
Low-temperature thermochronological and structural study of the inner Hardangerfjord area, southern Norway
(Master thesis, 2012-10-29)The origin of the mountainous topography in southern Norway is at present unresolved. Post-Devonian sediments are absent onshore, making quantification of crustal uplift and fault displacements difficult. Low-temperature ... -
Lower bounds on the size of spheres of permutations under the Chebychev distance
(Peer reviewed; Journal article, 2010)Lower bounds on the number of permutations p of {1, 2, . . . , n} satisfying |pi − i| ≤ d for all i are given -
Lower-Hybrid Drift Waves Driving Electron Nongyrotropic Heating and Vortical Flows in a Magnetic Reconnection Layer
(Journal article; Peer reviewed, 2020)We report measurements of lower-hybrid drift waves driving electron heating and vortical flows in an electron-scale reconnection layer under a guide field. Electrons accelerated by the electrostatic potential of the waves ... -
Lower-thermosphere–ionosphere (LTI) quantities: current status of measuring techniques and models
(Journal article; Peer reviewed, 2021)The lower-thermosphere–ionosphere (LTI) system consists of the upper atmosphere and the lower part of the ionosphere and as such comprises a complex system coupled to both the atmosphere below and space above. The atmospheric ... -
LTX-315: a first-in-class oncolytic peptide that reprograms the tumor microenvironment
(Peer reviewed; Journal article, 2017)The oncolytic peptide LTX-315, which has been de novo designed based on structure–activity relationship studies of host defense peptides, has the ability to kill human cancer cells and induce specific anticancer immune ... -
Lukket merdsystem - AquaDomen: Effekt på smittedynamikk
(Master thesis, 2012-06-04)Oppdrettsnæringen har blitt kritisert for å ha en negativ innvirkning på omliggende miljø, der smitteoverføring av ulike agens til ville laksepopulasjoner er et stort problem. Det er også reist bekymring ved den genetiske ... -
Luminosity determination in pp collisions at s=7 TeV using the ATLAS detector at the LHC
(Peer reviewed; Journal article, 2011-04-27)Measurements of luminosity obtained using the ATLAS detector during early running of the Large Hadron Collider (LHC) at s=7 TeV are presented. The luminosity is independently determined using several detectors and multiple ... -
Lumpfish Cyclopterus lumpus reproduction: Pituitary gene expression, physiological and morphological changes accompanying gonadal maturation
(Journal article; Peer reviewed, 2022)Lumpfish is the most important cleanerfish species in Atlantic salmon farming. Detailed information on the gonadal maturation process is a prerequisite for year-round production of juvenile lumpfish. In the present study ... -
The Lærdal-Gjende Fault: A detailed structural and thermochronological study
(Master thesis, 2015-06-01)The development of the Caledonian orogen to a passive margin leaded to the present-day Norwegian landscape. The most recent denudation history in Mesozoic and Cenozoic times holds the key to the morphotectonic development ... -
Læreboka si rolle i evolusjonsundervisninga
(Master thesis, 2021-05-31)Evolusjonsteorien er den store samlande ideen i biologivitskapen, og det er derfor viktig at befolkninga generelt har kunnskap om han. Skulen er den staden der det er størst potensiale for at opplysning om denne sentrale ... -
Lærers diskursive grep for å tilrettelegge for at elevene selv oppdager kunnskap
(Master thesis, 2022-03-21)I Fagfornyelsen står det at «Kjemi skal bidra til at elevene utvikler kreativitet og utfolder utforskertrang gjennom eksperimentelt og utforskende arbeid. Videre skal faget bidra til at elevene anerkjenner verdien av ... -

Læring av naturfag og matematikk gjennom prosjekter i teknologi og design
(Journal article, 2006)Jeg nærer en uro. Fagområdet teknologi og design skal inkluderes i matematikkfaget, samt i naturfag og kunst og håndverk. Men vil elevene kunne lære naturfag og matematikk eller få økt innsikt i hvordan anvende naturfag ... -
Læring hos biologistudenter: En kvantitativ pilotstudie av læringsmønstre blant førsteårsstudenter i biologi
(Master thesis, 2019-06-21)For studenter er det viktig å ha gode strategier for å lære, ikke bare i studiehverdagen men også for senere deltakelse i arbeidslivet. Innsikt i studenters bruk av læringsstrategier kan danne et grunnlag for utvikling av ...
