Observasjoners rolle for refleksjoner og kritisk tenkning
(Master thesis, 2021-06-01)Det er økende fokus på kritisk tenkning og utforskende undervisning i den nye læreplanen (Utdanningsdirektoratet, 2019). I den anledning har jeg i denne masteroppgaven tatt utgangspunkt i problemstillingen: «Hvordan kommer ... -
Oil absorption stability of modified cellulose porous materials with super compressive strength in the complex environment
(Journal article; Peer reviewed, 2023)The occurrence of oil spills has severe damage upon both the environment and human health. Hence, the development of a green, recyclable, complex environment resistant, and efficient oil–water separation aerogel is required ... -
Oil droplet fouling and differential toxicokinetics of polycyclic aromatic hydrocarbons in embryos of Atlantic haddock and cod
(Peer reviewed; Journal article, 2017-07-05)The impact of crude oil pollution on early life stages (ELS) of fish, including larvae and embryos, has received considerable attention in recent years. Of the organic components present in crude oil, polycyclic aromatic ... -
«Okei, hvilken konklusjon kan vi trekke ut fra det?» Ein kvalitativ studie av kjenneteikn ved lærars bruk av spørsmål og innspel i utforskande gruppediskusjonar
(Master thesis, 2021-06-01)Å vere lærar i dagens klasserom inneber i langt større grad enn før å la elevane vere aktive deltakarar i eiga læring. Dette medfører at læraren i si undervisning kjem i direkte dialog med elevar, og at det læraren gjer i ... -
On the Modelling of Immiscible Viscous Fingering in Two Phase Flow in Porous Media
(Journal article; Peer reviewed, 2020)Viscous fingering in porous media is an instability which occurs when a low-viscosity injected fluid displaces a much more viscous resident fluid, under miscible or immiscible conditions. Immiscible viscous fingering is ... -
Oncolytic peptide LTX-315 induces an immune-mediated abscopal effect in a rat sarcoma model
(Peer reviewed; Journal article, 2017)LTX 315 is an oncolytic peptide with potent immunological properties. In the present study, we demonstrate that intratumoral treatment with LTX-315 resulted in a complete regression and systemic immune response in a rat ... -
One-step preparation of robust elastic plastic polyvinyl chloride sponges with a layered structure for highly efficient separation of water-in-oil emulsions
(Journal article; Peer reviewed, 2023)To address the environmental pollution and human health issues caused by oily wastewater and PVC plastic waste, a practical zero-waste solution has been developed. In this study, PVC sponges with superlipophilic and ... -
