Dette prosjektet er en oppfølging av et prosjekt gjennomført i 2011. Det er i prosjektet gitt en oversikt over hvilke fôrråvarer som er brukt i norsk lakseproduksjon i 2012 og hvor effektivt råvarene utnyttes i produksjonen av norsk laks. Det er også benyttet livssyklus analyse (LCA) til å beregne...
Prosjektet har tatt utgangspunkt i havet og dets bærekraftige ressurser med tanke på marin bioprospektering. Restråstoff fra fangst av norsk vårgytende sild (NVG-sild) er undersøkt for enzymer, bioaktive peptider og lipider samt funksjonelle proteiner med kommersielt potensiale. En har utviklet...
Trålfanget fisk har generelt hatt et rykte på seg for å være av dårligere kvalitet enn krokfanget fisk og det er skjedd svært lite teknologiutvikling de siste 30 årene i prosessering (fangstbehandling) av hvitfisk. Dette bidrar til at hvitfiskindustrien ligger etter lakseindustrien når det gjelder...
Gjennom de siste 10–15 år har det vært lite åpen forskning på industriell produksjon av pillede reker. I samme tidsrom har industrien gjennomgått en omfattende strukturering og modernisering. Gjennom de seinere år har norsk rekeproduksjonen vært nedadgående som en konsekvens av sterk konkurranse fra...
Shifting toward sustainability and low carbon emission necessitates recycling. Aluminum alloys can be recycled from postconsumer scrap with approximately 5% of the energy needed to produce the same amount of primary alloys. However, the presence of certain alloying elements, such as copper and zinc...
Silicon alloys are produced by carbothermic reduction of quartz in a submerged arc furnace. This high-temperature pyrolytic process is a source of polycyclic aromatic hydrocarbons (PAHs), which are a group of aromatic organic molecules with known mutagenic and carcinogenic properties. In this study...
This paper presents a finite-control-set model predictive control (FCS-MPC) strategy for achieving power control in inductive power transfer (IPT) -based electric vehicle (EV) charging systems. The proposed control method is applied to a series-series-compensated IPT system when charging a battery...
Abstract Background Knowledge about meningioma growth characteristics is needed for developing biologically rational follow-up routines. In this study of untreated meningiomas followed with repeated magnetic resonance imaging (MRI) scans, we studied growth dynamics and explored potential factors...
Aim: To explore what municipal actors consider as inhibiting and promoting adolescents’ involvement in public health measures in municipalities. Methods: A qualitative study with individual and group interviews was conducted among 15 municipal actors who were central in involving adolescents from...
Herein, we present a synthesis route for high-efficiency nitrogen-doped carbon materials using kraft pulping residue, black liquor, and wood charcoal as carbon sources. The synthesized nitrogen-doped carbon materials, based on black liquor and its mixture with wood charcoal, exhibited high specific...
Polycyclic aromatic hydrocarbons (PAHs) are naturally present in raw materials used as a binder in prebaked anodes for electrolysis of aluminum. Green anodes are baked to about 1200 °C through a cycle of 14–17 days where organic hydrocarbon volatiles contribute to the carbonization process. Off...
Cost reduction in bipolar plates in proton exchange membrane water electrolyzers has previously been attempted by substituting bulk titanium with austenitic stainless steels protected with highly conductive and corrosion-resistant coatings. However, austenitic steels are more expensive than ferritic...
This work evaluated the effects of condensable syngas impurities on the cell viability and product distribution of Butyribacterium methylotrophicum in syngas fermentation. The condensates were collected during the gasification of two technical lignins derived from wheat straw (WST) and softwood (SW...
This paper proposes a method for formation path following control of a fleet of underactuated autonomous underwater vehicles. The proposed method combines several hierarchic tasks in a null space-based behavioral algorithm to safely guide the vehicles. Compared to the existing literature, the...
