Determination of the Effect of Constructed Wetlands on the Bioavailability of Phosphorus
(Masteroppgave/UIS-TN-IMN/2016;, Master thesis, 2016-06): Phosphorus is the limiting nutrient in most freshwater aquatic environments. When a large amount of phosphorus enters a freshwater environment, such as a lake, this causes a rapid increases in primary production which ... -
Development of Plant Hemoglobin-Based Blood Substitute: Fed-Batch Fermentation Optimization and Stability Characterization
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-07)The need for alternative blood substitutes is undoubtedly very enormous. Therefore, it is important to evaluate and develop different sources of starting material for this product. Focus has been on use of hemoglobin (Hb) ... -
DNA glycosylase activities for N4,5-dimethylcytosine
(Master thesis, 2017-06)Although the epigenetic DNA base 5-methylcytosine (m5C) has an important role in cellular functions, damaging chemical alterations to m5C have been little studied. For example, while much knowledge exists on erroneous ... -
DREAM (Dose-related Risk and Exposure Assessment Model) as a tool to predict biomarker responses in offshore produced water discharge situations
(Masteroppgave/UIS-TN-IMN/2009, Master thesis, 2009-11-25)Every year, approximately 200 million tones of produced water are discharged into the sea by the Norwegian oil industry. Although rapidly diluted, due to its large amount and possible long term (chronic) effects, the ... -
