Plantwide Control for Economically Optimal Operation of Chemical Plants: - Applications to GTL plants and CO2 capturing processes
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:265, Doctoral thesis, 2011)In this thesis, the systematic plantwide procedure of Skogestad (2004) is applied to two processes; 1- Post-combustion CO2 capturing processes, 2- Natural gas to liquid hydrocarbons (GTL) plants, in order to design ... -
Plantwide control of alkaline water electrolyzer plant for hydrogen production
(Master thesis, 2020)I arbeidet med å dempe klimagassutslipp er utvikling av teknologier som reduserer avhengigheten av fossile brenselbaserte energikilder uunnværlig. For tiden tilbyr hydrogenbaserte teknologier som involverer utvikling av ... -
Plantwide control of an oil production network
(Peer reviewed; Journal article, 2020)In this paper, we consider Real-Time Optimization (RTO) and control of an oil production system. We follow a systematic plantwide control procedure. The process consists of two gas-lift oil wells connected to a pipeline-riser ... -
Plantwide- and Self-Optimizing Control of a Reactor with Recycle Process
(Master thesis, 2013)Plantwide control is a very important topic in today?s process plants in a lot of different industries. With a large number of interacting process units, it is not enough to design a control structure for each single unit ... -
Plasma 25-hydroxyvitamin D associated with pulmonary function in Canadian adults with excess adiposity
(Journal article; Peer reviewed, 2013)Background: Vitamin D deficiency is an important health issue, particularly among people residing in northern countries. Low concentrations of 25-hydroxyvitamin D [25(OH)D] have been linked to several health conditions. ... -
Plasma 3-hydroxyisobutyrate (3-HIB) and methylmalonic acid (MMA) are markers of hepatic mitochondrial fatty acid oxidation in male Wistar rats
(Peer reviewed; Journal article, 2021)Objective Discovery of specific markers that reflect altered hepatic fatty acid oxidation could help to detect an individual's risk of fatty liver, type 2 diabetes and cardiovascular disease at an early stage. Lipid and ... -
Plasma apolipoprotein E levels in longitudinally followed patients with mild cognitive impairment and Alzheimer’s disease
(Peer reviewed; Journal article, 2022)Background Low levels of plasma apolipoprotein E (apoE) and presence of the APOE ε4 allele are associated with an increased risk of Alzheimer’s disease (AD). Although the increased risk of AD in APOE ε4-carriers is ... -
Plasma complement and vascular complement deposition in patients with coronary artery disease with and without inflammatory rheumatic diseases
(Journal article; Peer reviewed, 2017)Purpose Inflammatory rheumatic diseases (IRD) are associated with accelerated coronary artery disease (CAD), which may result from both systemic and vascular wall inflammation. There are indications that complement may ... -
Plasma concentrations and dietary intakes of choline and betaine in association with atrial fibrillation risk: Results from 3 prospective cohorts with different health profiles
(Journal article; Peer reviewed, 2018)Background: Although choline metabolism has been associated with atherosclerotic heart disease, less research attention has been paid to the associations of choline and its oxidative metabolite betaine with cardiac ... -
Plasma concentrations of organohalogenated contaminants in white-tailed eagle nestlings – The role of age and diet
(Journal article; Peer reviewed, 2019)Concentrations of organohalogenated contaminants (OHCs) can show significant temporal and spatial variation in the environment and wildlife. Most of the variation is due to changes in use and production, but environmental ... -
