Merging and comparing three mitochondrial markers for phylogenetic studies of Eurasian reindeer (Rangifer tarandus)
(Journal article; Peer reviewed, 2016)Phylogenetic analyses provide information that can be useful in the conservation of genetic variation by identifying intraspecific genetic structure. Reconstruction of phylogenetic relationships requires the use of markers ... -
"Minoritised mathematics students are motivated by gratitude": An analysis of storylines in Norwegian public media
(Peer reviewed; Journal article, 2021)As part of a larger participatory research project, we examine storylines about mathematics education and students from minoritised cultures and/or languages in Norwegian news media. We identify some of the positionings ... -
Modeling and Analysis of Fluid Flow through A Non-Prismatic Open Channel with Application to Drilling
(Journal article; Peer reviewed, 2018)This paper presents the development and validation of a simplified dynamic model of a Venturi channel. The existing dynamic models on open channels are based on the open channel flow principles, which are the shallow water ... -
Modelling and Simulation of Detection Rates of Emergent Behaviours in System Integration Test Regimes
(Peer reviewed; Journal article, 2021)System level testing generally lacks coverage due to cost of performing realistic tests on the “system as a whole”. This lack in test coverage gives rise to seemingly emergent aviour at system level. The interactions between ... -
Norske jenter og gutter i ungdomsskolen har blitt likere i naturfaginteresse – men mer ulike når det gjelder miljøengasjement. Første resultater fra den norske ROSES-undersøkelsen 2020
(Peer reviewed; Journal article, 2022)I denne artikkelen presenterer vi data fra en spørreundersøkelse i 2019/20 blant norske 10. klassinger om naturfag og teknologi. Undersøkelsen (kalt ROSES) bygger på ROSE-prosjektet, som ble ledet av Svein Sjøberg i første ... -
Nærmiljø som læringsarena i undervisning for bærekraftig utvikling. En analyse av læreres erfaringer og refleksjoner
(Journal article; Peer reviewed, 2018)Despite an increased focus on education for sustainable development (ESD), many teachers still report insecurity in how to implement ESD in their practice. This study examined teachers’ reflections from using the local ... -
Oi! Sjå på den! – Funn av naturelement som utgangspunkt for utforskande naturfaglege samtalar mellom barn (5-6 år) og pedagogar
(Peer reviewed; Journal article, 2020)The study examines what characterizes situations that facilitate young children´s participation in exploratory scientific dialogues in outdoor education. By using action cameras mounted to the chest of three children (5-6 ... -
On equivalence and cores for incomplete databases in open and closed worlds
(Chapter, 2020)Data exchange heavily relies on the notion of incomplete database instances. Several semantics for such instances have been proposed and include open (OWA), closed (CWA), and open-closed (OCWA) world. For all these semantics ... -
On Uncertainty Analysis of the Rate Controlled Production (RCP) Model
(Peer reviewed; Journal article, 2021)Rate controlled production (RCP) model is used to simulate and investigate the performance of the oil wells which are completed by autonomous inflow control devices. In order to quantify the performance of the RCP model, ... -
Parameter Estimation for a Gas Lifting Oil Well Model Using Bayes' Rule and the Metropolis–Hastings Algorithm
(Peer reviewed; Journal article, 2022)Oil well models are frequently used in the oil production process. Estimation of unknown parameters of these models has long been a question of great interest in the oil industry field. Data collected from an oil well ... -
Programmering og geometri
(Peer reviewed; Journal article, 2020)Denne artikkelen ser på hvordan programmering kan implementeres i klasserommet i grunnskolen og hvordan programmering kan brukes som et verktøy for utforskning av geometri i matematikkfaget. Artikkelen tar for seg en måte ... -
Science teachers' pedagogical content knowledge development during enactment of socioscientific curriculum materials
(Peer reviewed; Journal article, 2019)The purpose of this study is to provide insight into short‐term professionalization of teachers regarding teaching socioscientific issues (SSI). The study aimed to capture the development of science teachers' pedagogical ... -
Storylines in public news media about mathematics education and minoritized students
(Peer reviewed; Journal article, 2022)Public media both reflects and shapes societal perceptions and attitudes. Teachers and others around students in mathematics classrooms have expectations for the students, projected with what appears in these media. We are ... -
Stress-mediated reprogramming of prostate cancer one-carbon cycle drives disease progression
(Peer reviewed; Journal article, 2021)One-carbon (1C) metabolism has a key role in metabolic programming with both mitochondrial (m1C) and cytoplasmic (c1C) components. Here we show that activating transcription factor 4 (ATF4) exclusively activates gene ... -
