Photodegradable antimicrobial agents - synthesis, photodegradation, and biological evaluation
(Journal article; Peer reviewed, 2021)Multi-drug resistant (MDR) bacteria are already a significant health-care problem and are making the combat of infections quite challenging. Here we report the synthesis of several new compounds containing an ethanolamine ... -
Photodegradable Antimicrobial Agents: Synthesis and Mechanism of Degradation
(Journal article; Peer reviewed, 2022)As a strategy to inactivate antimicrobial agents after use, we designed a range of ethanolamine derivatives where four of them possessed interesting activity. The ethanolamine moiety facilitates photodecomposition, which ... -
Physical activity intensity profiles associated with cardiometabolic risk in middle-aged to older men and women
(Journal article; Peer reviewed, 2022)Accelerometers provide detailed data about physical activity (PA) across the full intensity spectrum. However, when examining associations with health, results are often aggregated to only a few summary measures [e.g. time ... -
Physical Chemistry of Mechanisms for Low Salinity Waterflood
(Master thesis, 2013-10-23)Low salinity injection as an alternative EOR method to enhance the production of reserves has for decades been investigated. Increasing evidence that reduction in brine salinity can cause a significant impact on the oil ... -
Physico-Chemistry Characterization of Sulfonated Polyacrylamide Polymers for Use in Polymer Flooding
(Doctoral thesis, 2010-06-01)Hydrolyzed polyacrylamide polymer (HPAM) as a feasible and effective viscosifier has been fully studied and used for polymer flooding processes in several oil field, e.g. Daqing oil field. It has been shown that Hydrolyzed ... -
Polar Components in Crude Oils and Their Correlation to Physiochemical Properties.
(Master thesis, 2016-06-01)The composition and properties of crude oils have been subjected to much scrutinization over the past decades due to the decreasing oil quality and thus increasingly difficult oil recovery. The physical properties of crude ... -
Polymer flow in porous media: Relevance to Enhanced Oil Recovery
(Peer reviewed; Journal article, 2018-07-10)Polymer flooding is one of the most successful chemical EOR (enhanced oil recovery) methods, and is primarily implemented to accelerate oil production by sweep improvement. However, additional benefits have extended the ... -
Polymer Injectivity : Experimental Studies of Flow in Porous Media for EOR Polymers
(Doctoral thesis, 2021-02-12)Despite the maturity of the polymer flooding process that is applied in enhanced oil recovery (EOR) technologies, the core of the process, which is the flow of the polymer in porous media, is poorly understood. The types ... -
Polymer Injectivity Test Design Using Numerical Simulation
(Journal article; Peer reviewed, 2020-04-03)Polymer flooding is an enhanced oil recovery (EOR) process, which has received increasing interest in the industry. In this process, water-soluble polymers are used to increase injected water viscosity in order to improve ... -
Polymer Injectivity: Investigation of Mechanical Degradation of Enhanced Oil Recovery Polymers Using In-Situ Rheology
(Peer reviewed; Journal article, 2018-12-24)Water soluble polymers have attracted increasing interest in enhanced oil recovery (EOR) processes, especially polymer flooding. Despite the fact that the flow of polymer in porous medium has been a research subject for ... -
Potential for bio-oil production from biodiesel production residues, with emphasis on African feedstocks
(Master thesis, 2017-01-30)Utilization of waste products from biomass have been scarcely research on. These wastes have been a major environmental hazard which involves a lot of capital and effort to curb. Thermochemical conversion using the LtL ... -
Predicting the Skin Sensitization Potential of Small Molecules with Machine Learning Models Trained on Biologically Meaningful Descriptors
(Journal article; Peer reviewed, 2021)In recent years, a number of machine learning models for the prediction of the skin sensitization potential of small organic molecules have been reported and become available. These models generally perform well within ... -
Predictive associations between serum fatty acids and lipoproteins in healthy non-obese Norwegians: implications for cardiovascular health
(Peer reviewed; Journal article, 2016-01)A battery of methods for multivariate data analysis has been used to assess the associations between concentrations of fatty acids (FAs) and lipoprotein subclasses and particle size in serum for a normolipidemic population ... -
Preliminary observations of the interplay of radiation damage with spin crossover
(Journal article; Peer reviewed, 2022)Intense synchrotron radiation makes time-resolved structural experiments with increasingly finer time sampling possible. On the other hand, radiation heating, radiation-induced volume change and structural disorder become ... -
Probing Catalyst Degradation in Metathesis of Internal Olefins: Expanding Access to Amine-Tagged ROMP Polymers
(Journal article; Peer reviewed, 2023)Ruthenium-promoted ring-opening metathesis polymerization (ROMP) offers potentially powerful routes to amine-functionalized polymers with antimicrobial, adhesive, and self-healing properties. However, amines readily degrade ... -
