Micronutrient Distribution in Relation to Waste Emission from Aquaculture Activities: A field study in Trondheimsfjorden
(Master thesis, 2013)Bioactive trace metals, or micronutrients, are crucial as cofactors in enzymes used in various macronutrient cycles in marine systems. Aquaculture releases large quantities of macronutrients, which may lead to a shift in ... -
Microplastic accumulation by tube-dwelling, suspension feeding polychaetes from the sediment surface: A case study from the Norwegian Continental Shelf
(Peer reviewed; Journal article, 2020)Sediment samples (0–1 cm) and tube-dwelling polychaetes from the Norwegian Continental Shelf and the Barents Sea were collected, including areas close to oil and gas installations and remote locations. Microplastics (≥45 μm) ... -
Microplastic fibres from synthetic textiles: Environmental degradation and additive chemical content
(Peer reviewed; Journal article, 2021)Microplastic fibres (MPFs) often make up the largest fraction of microplastic pollution in aquatic environments, yet little is known about their degradative fate and persistence. This study investigates the environmentally ... -
Microplastic Pollution in the Volta River Delta’s Blue Carbon Mangrove Ecosystem in Ghana
(Master thesis, 2023)Denne oppgaven har tatt del i BC5 og Sailing 4 Science. BC5 eller "Building Capacity to Crosslink Coastal Pollution with Climate Change" er et prosjekt finansert av Norad under programmet "Climate change and Natural ... -
Microwave assisted synthesis of pyrimidinyl 3,4-dihydroquinazolin-2(1H)-imines - New compounds for biological evaluation
(Master thesis, 2024)Enzymet «nei like DNA glycosylase 2» (NEIL2) bidrar til reparasjon av oksidative skader på DNA. Mens NEIL2 kan begrense skader av inflammasjoner, viser undersøkelser, som denne masteroppgaven er basert på at hemming også ... -
Mie–FH: A quantum corrected pair potential in the LAMMPS simulation package for hydrogen mixtures
(Journal article; Peer reviewed, 2024)Several knowledge gaps on the properties and behavior of hydrogen must be closed to realize its widespread use as a clean fuel and reduction agent. A challenge in this regard is that hydrogen and its mixtures are influenced ... -
Miljøgifter i barns lekemiljø
(Master thesis, 2008)Denne oppgaven undersøker ti sentrumsnære barnehager i Trondheim. Det blir sett på jordforurensning, innhold av miljøgifter i trevirke og maling som er brukt i barnehagen og det blir tatt vaskeprøver av hendene til barna ... -
Miljøgifter i elektrisk og elektronisk avfall
(Master thesis, 2013)Produksjonen av elektriske og elektroniske (EE) produkter øker globalt, og dermed øker også mengden EE-avfall betydelig. Eksempler på EE-produkter er TV-apparater, mobiltelefoner, datamaskiner, komfyrer, kabler og ledninger. ... -
Miljøkartlegging av strøsand fra ulike geografiske lokaliteter i Trondheim, samt utlekkingsstudier av tungmetaller i forbindelse med gjenbruk.
(Master thesis, 2014)Flere kommuner, deriblant Trondheim kommune, vurderer gjenbruk av strøsanden som blir samlet opp fra veier, gang og sykkelsti. For å kunne gjenbruke strøsanden på en samfunnsøkonomiske og miljømessig måte diskuteres blant ... -
Miljøvennlege metodar for å måle tungmetall i marint vatn ved bruk av kjemiske sensorar

Minimization of entropy production in separate and connected process units
(Dr. ingeniøravhandling, 0809-103X; 2004:111, Doctoral thesis, 2004) -
Minimum entropy production in a distillation column for air separation described by a continuous non-equilibrium model
(Journal article; Peer reviewed, 2020)In this work, we apply the rate-based model of Taylor and Krishna to describe the separation of air in a low-pressure, packed distillation column. By use of numerical optimization, we identify the temperature profile for ... -
Mobility of Elements at the Sediment Water Interface in a Simulated Sub-Seabed CO2 Seepage Site
(Master thesis, 2018)Carbon capture and storage (CCS) is an important technology for the mitigation of global warming. However, prior research has indicated that CO2 escape through marine sediment can lead to the acidification of sediment pore ... -
Mode of Application of Peracetic Acid-Based Disinfectants has a Minimal Influence on the Antioxidant Defences and Mucosal Structures of Atlantic Salmon (Salmo salar) Parr
(Peer reviewed; Journal article, 2022)Peracetic acid (PAA) is an oxidative disinfectant with a broad spectrum of antimicrobial activity and low environmental impact. In this study, we investigated the physiological impacts of PAA application in Atlantic salmon ... -
Modeling Chemistry in QED Cavities using Coupled Cluster
(Master thesis, 2019)I denne avhandlingen introduseres kvanteelektrodynamisk ''coupled cluster'' teori (QED-CC) som en ny og nøyaktig ab initio teori for å undersøke sterk kobling mellom lys og materie i optiske kaviteter. Ligningene for ... -
Modeling enviromental effects with coupled cluster and particle-breaking Hartree-Fock theory
(Doctoral theses at NTNU;2024:159, Doctoral thesis, 2024)Chemical phenomena commonly occur within specific environments, such as solutions or surfaces. An emerging area, termed on-water catalysis, exemplifies this, where chemical reactions experience significant acceleration at ... -
Modeling Molecular Properties of Interest for Streamer Studies
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:250, Doctoral thesis, 2010)If an insulating material is stressed by sufficiently large electric field, a plasma channel may be created which destroys the materials insulating properties. The processes involved are complicated and the field of research ... -
