Environmentally Friendly Phosphonated Polyetheramine Scale Inhibitors - Excellent Calcium Compatibility for Oilfield Applications
(Peer reviewed; Journal article, 2020-05)Scaling is one of the most frequently stated problems in the oil industry, and scale inhibitors (SIs) are applied to prevent its formation. Organophosphonates are well-known types of SIs, particularly useful for squeeze ... -
The escherichia coli alkA gene is activated to alleviate mutagenesis by an oxidized deoxynucleoside
(Peer reviewed; Journal article, 2020)The cellular methyl donor S-adenosylmethionine (SAM) and other endo/exogenous agents methylate DNA bases non-enzymatically into products interfering with replication and transcription. An important product is 3-methyladenine ... -
Estimating diagnostic uncertainty in artificial intelligence assisted pathology using conformal prediction
(Peer reviewed; Journal article, 2022)Unreliable predictions can occur when an artificial intelligence (AI) system is presented with data it has not been exposed to during training. We demonstrate the use of conformal prediction to detect unreliable predictions, ... -
Evaluation of Biogas Production Potential of Glycol-Containing Industrial Waste from Kårstø Processing Plant
(Masteroppgave/UIS-TN-IKBM/2019;, Master thesis, 2019-07-06)This research has been carried out to investigate the potential for methane gas production from untreated glycol containing industrial waste water from Kåstrø gas refinery, Tysvær Norway. Biogas methane potential (BMP) has ... -
Evaluation of microalgae nutrient removal efficiency from wastewater cultivated in a photobioreactor under non-ideal conditions.
(Masteroppgave/UIS-TN-IKBM/2019;, Master thesis, 2019-12-14)The scope of this project is to Study the long-term performance and wastewater nutrients removal efficiency by microalgae in a PBR under no favourable conditions. COD, TN, TP, NH4+-N, NO3--N, PO43--P, TSS and pH values ... -
Evaluation of photodegradable chitin synthetase inhibitors for the treatment of salmon lice (Lepeophtheirus salmonis)
(Peer reviewed; Journal article, 2023)Some photolabile ethanolamine analogues of the chitin synthetase inhibitors diflubenzuron, teflubenzuron, and lufenuron were tested for activity as anti-lice compounds towards salmon lice (Lepeophtheirus salmonis). Two ... -
Evaluation of polycyclic aromatic hydrocarbon metabolites in whale bile
(Bachelor thesis, 2021)The potential presence of PAH metabolites, expressed as PFE, in whale bile demonstrate the possibility of evaluating PAH contamination in this species using a real peak reading at the traditional excitation wavelengths. In ... -
Evaluation of response to environmental pollution in Atlantic cod
(Bachelor thesis, 2022)In this thesis the response to environmental pollution in Atlantic cod (Gadus morhua) caged in the Stavanger fjord is evaluated. Three separate locations were selected according to the waste water discharge plume on the ... -
Evolutionary analysis of cellular reduction and anaerobicity in the hyper-prevalent gut microbe Blastocystis
(Peer reviewed; Journal article, 2023)Blastocystis is the most prevalent microbial eukaryote in the human and animal gut, yet its role as commensal or parasite is still under debate. Blastocystis has clearly undergone evolutionary adaptation to the gut environment ... -
Evolutionary Maintenance of the PTS2 Protein Import Pathway in the Stramenopile Alga Nannochloropsis
(Peer reviewed; Journal article, 2020)The stramenopile alga Nannochloropsis evolved by secondary endosymbiosis of a red alga by a heterotrophic host cell and emerged as a promising organism for biotechnological applications, such as the production of polyunsaturated ... -
Excessive Daytime Sleepiness and REM Sleep Behavior Disorders in Parkinson's Disease: A Narrative Review on Early Intervention With Implications to Neuroprotection
(Journal article; Peer reviewed, 2018-11)Sleep contributes to the consolidation of our memory and facilitates learning. Short term sleep deprivation temporarily reduces mnestic capacity, whereas long lasting sleep deprivation is associated with structural changes ... -
