The human NAD metabolome: Functions, metabolism and compartmentalization
(Peer reviewed; Journal article, 2015)The metabolism of NAD has emerged as a key regulator of cellular and organismal homeostasis. Being a major component of both bioenergetic and signaling pathways, the molecule is ideally suited to regulate metabolism and ... -
Human-induced evolution caught in action: SNP-array reveals rapid amphi-atlantic spread of pesticide resistance in the salmon ecotoparasite Lepeophtheirus salmonis
(Peer reviewed; Journal article, 2014-10-26)Background: The salmon louse, Lepeophtheirus salmonis, is an ectoparasite of salmonids that causes huge economic losses in salmon farming, and has also been causatively linked with declines of wild salmonid populations. ... -
Hva tenker dere om de dere karbongreiene?
(Master thesis, 2023-06-01)Formålet med denne masteroppgaven har vært å få innsikt i samtaler mellom elever, og elever og lærer i gruppe og plenumssituasjoner i et utforskende opplegg med bålbrenning. Datamaterialet som danner grunnlaget for analysen, ... -
Hvordan jobber elever for å gi mening til nye og utfordrende begreper, og hvilke ressurser bruker de?
(Master thesis, 2021-06-01)De overordnede teamene for oppgaven er dialog i klasserommet og begrepsforståelse. Etter møte med elever i klasserommet gjennom praksis ble jeg oppmerksom på utfordringen med å skape begrepsforståelse blant elevene. Dette ... -
Hvordan klimaet kan endres - en innføring
(Book, 2012-08-07)Denne boka handler om det naturvitenskapelige grunnlaget for klimaendringer, om hvordan klimaet kan endres, hva vi vet og hva som er usikkert. En stor del av arbeidet til FNs klimapanel IPCC omfatter dette grunnlaget, de ... -
Hvordan løser elever i videregående skole beregningsoppgaver i kjemi? En kvalitativ studie av elevers prøvebesvarelser og oppgavebaserte intervjuer
(Master thesis, 2019-06-21)Beregninger er en viktig del av flere konsepter innenfor kjemi, og for tidligere forskning er det vist at gode matematikkferdigheter kan ses i lys med suksess i kjemi. Derfor er det ønskelig å nyansere forskningen ved å ... -
«Hvordan skal jeg kunne finne ut av det?» Ein kvalitativ studie av korleis elevar arbeider for å forstå tal og fakta som ikkje gir meining for dei
(Master thesis, 2020-07-17)Dei nye læreplanane skal legge til rette for djupnelæring. Dette medfører mellom anna at utforskande arbeid og kritisk tenking er sentrale satsingsområde i norsk skule. For å kunne fremme elevane sin kompetanse i å lære ... -
