Innsamling av kasserte mobiltelefoner i kommuner med henteordning for småelektronikk : en kartlegging og evaluering av innsamlingsgrad og klimagassutslipp
(Master thesis, 2013-03-26)Mobiltelefoner inneholder verdifulle metaller som er energikrevende og miljøbelastende å utvinne, i tillegg inneholder den toksiske stoffer. Resirkulering vil føre til store klimagevinster ved å erstatte utvinningen av ... -
Innsjøenes betydning som produksjonshabitat for laksesmolt; en undersøkelse av tetthet og vekst av laksunger i Roksdalsvassdraget i Nordland
(Master thesis, 2011-10-14)Flere vassdrag i Nord-Norge har bestander av atlantisk laks (Salmo salar) der ungene utnytter både innsjøer og elver som oppveksthabitat. Roksdalsvassdraget i Nordland er et slikt vassdrag. Tetthetsberegninger og vekststudier ... -
Integrasjon av vindkraft i energisystemet : effekten av variabilitet på markedsverdien
(Master thesis, 2014-09-17)Klimapolitikken bidrar til å fase ut termisk kraftproduksjon basert på fossile kilder. Dette kan føre til at en mindre andel av kraftproduksjonen kan respondere på prissignaler. Det er planlagt å øke andelen vindkraft i ... -
Inter-population variation in brown trout (Salmo trutta) life-history- and migration strategies in a clay-affected river system: live fast, die young!
