The ecological and evolutionary role of telomere length in house sparrows
(Doctoral theses at NTNU;2021:420, Doctoral thesis, 2021)Telomeres, the DNA sequences capping the ends of linear chromosomes, are ancient molecular structures that are shared among most eucaryotes. The telomeres protect chromosomes from degradation and are vital to genome ... -
Ecological dependencies make remote reef fish communities most vulnerable to coral loss
(Peer reviewed; Journal article, 2021)Ecosystems face both local hazards, such as over-exploitation, and global hazards, such as climate change. Since the impact of local hazards attenuates with distance from humans, local extinction risk should decrease with ... -
Ecological dynamics and large scale phenotypic differentiation in density-dependent populations
(Journal article; Peer reviewed, 2019)Spatial differentiation of phenotypes is assumed to be determined by a combination of fluctuating selection producing adaptations to the local environment and a homogenizing effect of migration. We present a model with ... -
Ecological Effects of Climate-Driven Salinity Variation in the San Francisco Estuary: Can We Anticipate and Manage the Coming Changes?
(Peer reviewed; Journal article, 2021)Climate change-driven sea level rise and altered precipitation regimes are predicted to alter patterns of salt intrusion within the San Francisco Estuary. A central question is: Can we use existing knowledge and future ... -
Ecological modeling of metabolic rates predicts diverging optima across food abundances
(Journal article; Peer reviewed, 2014)Genetically based variation in metabolic rates of resting animals (RMR) suggests a potential role for evolutionary adaptations, but mechanistic models yielding evolutionary predictions are lacking. Here I utilize the ... -
Ecological signals of arctic plant-microbe associations are consistent across eDNA and vegetation surveys
(Peer reviewed; Journal article, 2023)Understanding how different taxa respond to abiotic characteristics of the environment is of key interest for understanding the assembly of communities. Yet, whether eDNA data will suffice to accurately capture environmental ... -
Ecology and Conservation Challenges of the Kori bustard in the Serengeti National Park
(Doctoral theses at NTNU;2017:238, Doctoral thesis, 2017)The study focused on the ecology and conservation challenges of the Kori bustard in the Serengeti National Park. The main objectives of the study was to determine the factors that affect local ecological knowledge and ... -
Ecology, Behaviour and Conservation Status of Masai Giraffe (Giraffa camelopardalis tippelskirchi) in Tanzania
(Doctoral theses at NTNU;2016:285, Doctoral thesis, 2016)Globally, biodiversity resources have been in decline since mankind began to keep records of their surrounding environments. With the combination of different natural catastrophes over centuries and human-induced activities, ... -
Economic model predictive control in a large-scale green hydrogen plant
(Master thesis, 2023)De siste årene har det vært en betydelig økning i utnyttelsen av grønn hydrogen som en alternativ energiløsning, grunnet dets høye fleksibilitet og minimale miljøpåvirkning. Ifølge Hydrogen Council har det blitt publisert ... -
Economic Plantwide Control for a Methanol Plant using Commercial Process Simulation Software
(Master thesis, 2014)It is desired to make the Economic Plantwide Control design procedure proposed by Skogestad (2000, 2004, 2012) available for engineers without deep knowledge of process control or optimization. The integration of the use ... -
Economical Synthesis of 13C-Labeled Opiates, Cocaine Derivatives and Selected Urinary Metabolites by Derivatization of the Natural Products
(Journal article; Peer reviewed, 2015)The illegal use of opiates and cocaine is a challenge world-wide, but some derivatives are also valuable pharmaceuticals. Reference samples of the active ingredients and their metabolites are needed both for controlling ... -
Ecosystem carbon stocks in Danish deciduous forests: impact of land-use history and management on major carbon pools
(Master thesis, 2023)Skog er viktig karbonsluk, og bidrar med å hjelpe å dempe klimaendringene. Bærekraftig forvaltning av skogen er nødvendig for å kunne maksimere effekten av karbonslukene. Effekten av tidligere arealbruk, og nåværende ... -
Ecotoxicological impacts of surface water and wastewater from conventional and advanced treatment technologies on brood size, larval length, and cytochrome P450 (35A3) expression in Caenorhabditis elegans
(Journal article; Peer reviewed, 2018)Anthropogenic micropollutants and transformation products (TPs) negatively affect aquatic ecosystems and water resources. Wastewater treatment plants (WWTP) represent major point sources for (micro)pollutants and TPs in ... -
Edge functionalization of finite graphene nanoribbon superlattices
(Journal article; Peer reviewed, 2019)The effect of chemical functionalization on the electronic properties of graphene nanoribbon superlattices with zigzag and armchair terminations is investigated using the density functional theory. The calculated positive ... -
Edge interfaces of the Ω plates in a peak-aged Al-Cu-Mg-Ag alloy
(Journal article; Peer reviewed, 2022)The coherent edge interface structures of the relatively thin {111}Al Ω plates have been analyzed in a peak-aged Al-Cu-Mg-Ag alloy by atomic-resolution scanning transmission electron microscopy (STEM). Analysis of STEM ... -
Edge-modified zigzag-shaped graphene nanoribbons: structure and electronic properties
(Journal article; Peer reviewed, 2014)Control of the band gap of graphene nanoribbons is an important problem for the fabrication of effective radiation detectors and transducers operating in different frequency ranges. The periodic edge-modified zigzag-shaped ... -
Edge/basal/defect ratios in graphite and their influence on the thermal stability of lithium ion batteries
(Journal article, 2016)Raw graphite can be processed industrially in large quanta but for the graphite to be useful in lithium ion batteries (LIB's) certain parameters needs to be optimized. Some key parameters are graphite morphology, active ... -
