(Master thesis, 2021)The primary aim of this thesis was to investigate the process of biosorption and explore its suitability and effectiveness for use in Norway for the removal of heavy metals from wastewater. A qualitative assessment was ... -
Photodegradable antimicrobial agents - synthesis, photodegradation, and biological evaluation
(Peer reviewed; Journal article, 2021-09)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 ... -
pH-Driven Solubilization and Isoelectric Precipitation o Proteins from The Red Seaweeds Vertebrata lanosa and Palmaria palmata -Effects of pH, Water Volume, Time and Temperature on Protein Yield
(Master thesis, 2021)Proteins take part in virtually every process within the cell. They are a vital component of any diet as a source of energy and essential amino acids (EEA) that the body is not capable of synthesizing. Without supplements, ... -
Studying of lumpfish sheltering using natural and artificial seaweed.
(Master thesis, 2021)The aim of this thesis was to evaluate the welfare of the lumpfish (Cyclopterus lumpus) by studying fish behaviour in different habitats, consisting of artificial and natural seaweed hides. Substrates and hides are essential ... -
Environmental Risk Assessment of Seven Potential Enhanced Oil Recovery Partitioning Inter-Well Tracer Candidates.
(Master thesis, 2021)An environmental risk assessment was conducted to characterise and compare the risk of seven shortlisted partitioning inter-well tracer candidates. The candidates were: Pyridine, 2-3-Dimethylpyrazine, 2,6-Dimethylpyrazine, ... -
Development of Naval Controlling Loops for Primary Sludge Thickening Process at SNJ Wastewater Treatment Plant
(Master thesis, 2021)The solid concentration of primary sludge is increased by thickening process of the wastewater treatment plant (WWTP). At SNJ WWTP, rotary drum thickener is used to thicken primary sludge and expected to obtain 5 ±1 % ... -
Uracil-excising activity of hSMUG1 in bubble and R-loop DNA
(Master thesis, 2021)Uracil arises in cellular DNA by hydrolytic cytosine (C) deamination and by erroneous repli-cative incorporation of deoxyuridine monophosphate opposite adenine. The former event is devastating by generation of C thymine ... -
Potential of ultrasound technology towards improvement of protein gel systems as affected by thermal and high-pressure processing as pre-treatment.
(Master thesis, 2021)The potential of ultrasound (US) to modify structural and functional properties in complex protein food systems has gained more interest in recent years.US-enhanced gelling properties have been demonstrated in acid ... -
Replacing Pro240 with Gly in hSMUG1 increases uracil excision in R-loop but abolish 5-hydroxymethyluracil excision in ssDNA
(Master thesis, 2021)Deamination and oxidation of pyrimidines are two major spontaneously damaging events in DNA. The DNA glycosylase SMUG1 initiates repair of deaminated or oxidized bases by breaking the glycosidic bond between the damaged ... -
Volatile organic compounds in greenhouse: Discovery of volatile biomarkers related to fungal infection by Botrytis cinerea in tomato plants
(Master thesis, 2021)The development of fungal disease in greenhouse plants can result in limited production and great economic losses for the producer. Early detection and identification of disease in plants before visible symptoms appear, ... -
Excision of 5-hydroxymethyluracil in single-stranded DNA by hSMUG1 requires Ser26 and/or Glu35 and Pro240
(Master thesis, 2021)The integrity of the genetic material of all organisms is assaulted continuously by a multitude of endogenous and exogenous agents throughout its lifetime, where the DNA bases of the genetic code may be altered if not ... -
Ball milling as a green mechanochemical method for synthesis of phosphonated oilfield scale inhibitors
(Bachelor thesis, 2021)Scale formation is a major problem in the oil and gas industry. Through different production processes seawater and formation water mix. The minerals present in each cause sparingly soluble salts to precipitate and deposit. ... -
Synthesis, characterization, and Batch adsorption analysis of Spent coffee grounds, Chitosan, and PVA composite beads for the removal of Cadmium and Lead from aqueous solutions.
(Master thesis, 2021)Adsorption of Cadmium and Lead in aqueous solutions by Spent coffee grounds/chitosan/PVA composite beads was studied. An adsorption Batch experimental model was used to determine the Isotherms and kinetics of 4 different ... -
Major bioactive chemical compounds in Astragali Radix samples from different vendors vary greatly
(Peer reviewed; Journal article, 2021-07)The worldwide traditional Chinese medicine (TCM) herbs sales figures have increased considerably to 50 billion US$ (2018). Astragali Radix (AR) is amongst the most often sold TCM herbs; sales in the European Union (EU) ... -
Development of tacrine clusters as positively cooperative systems for the inhibition of acetylcholinesterase
(Peer reviewed; Journal article, 2021-07)The synthesis of four tetra-tacrine clusters where the tacrine binding units are attached to a central scaffold via linkers of variable lengths is described. The multivalent inhibition potencies for the tacrine clusters ... -
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 ... -
Bioaccumulation of amitriptyline via the sediment in the benthic species Nereis virens
(Master thesis, 2021)The presence of antidepressants and other pharmaceuticals in micro concentrations in the marine environment have, in recent years, become a focal area for ecotoxicology. These compounds might have unexpected impacts on ... -
Methylation of PP2A in Arabidopsis thaliana - effects on gene expression and phenotype
(Bachelor thesis, 2021)Methylation of the carboxyl group in PP2A and formation of the PP2A holoenzyme is a highly regulated process. The catalyzer of this process is Leucine carboxyl methyl transferase 1 (LCMT1). PP2A-C methylation is essential ...
