PAH mixture toxicity in early Zebrafish developement
(Master thesis, 2023)Zebrafish is a vertebrate model largely used in ecotoxicology to unveil and predict the effects of hazardous substances that are present in the aquatic environment. However, more research is needed on developmental adverse ... -
Pathogen Removal form Domestic Wastewater Using Membrane Filter
(Masteroppgave/UIS-TN-IKBM/2019;, Master thesis, 2019-06-14)The study assessed the use of membrane filter for the removal of harmful pathogens and other microorganisms from domestic wastewater. Effluent wastewater from the UASB reactor was used as feed for the membrane filter. The ... -
Pathogenic Bacteria and Antibiotic Resistance Gene Removal Using Up-flow Anaerobic Sludge Blanket (UASB)
(Masteroppgave/UIS-TN-IKBM/2019;, Master thesis, 2019-06-15)The search for effective wastewater management strategies continues and never stops due to the importance of ensuring a safe environment for all organisms. The Upflow Anaerobic Sludge Blanket (UASB) reactor is cost-effective, ... -
Performance of Enzyme-Catalyzed Single-E and Dual-E Homeostatic Controllers
(Masteroppgave/UIS-TN-IKBM/2020;, Master thesis, 2020-06-15)Mathematical modeling has become an important tool in order to investigate the behavior of biological systems. The concept of homeostasis is central to our understanding how cells and organisms maintain an internal stability ... -
Performance of Waterborne Polyurethanes in Inhibition of Gas Hydrate Formation and Corrosion: Influence of Hydrophobic Fragments
(Peer reviewed; Journal article, 2020-12)The design of new dual-function inhibitors simultaneously preventing hydrate formation and corrosion is a relevant issue for the oil and gas industry. The structure-property relationship for a promising class of hybrid ... -
Permeability evolution of shear failing chalk cores under thermochemical influence
(Peer reviewed; Journal article, 2020-04)Development of petroleum reservoirs, including primary depletion of the pore pressure and repressurization during water injection naturally, leads to changes in effective stresses of the formations. These changes impose ... -
