Synthesis of tubastrine analogues as potential antifouling agents
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-07-12)In recent years, several isolated natural products containing a guanidine group have proven to have antibacterial effects. Preparation of such molecules synthetically is therefore highly relevant for mitigation and control ... -
Synthesizing and Testing for New Biodegradable Scale Inhibitors
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-06)A common production problem for oilfield operation is the formation of inorganic scale in the wellbore, surface facilities and near wellbore formation. Scale formation causes loss in production in most of the production ... -
Targeted mutagenesis of peroxisomal protein phosphatases using CRISPR-Cas9 approach
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-06)The newest development in the techniques of gene editing is the clustered regularly interspaced short palindromic repeat - associated protein9 (CRISPR-Cas9). This is a complex consisting of single-guide RNA (sgRNA) and a ... -
Temperature dependence of naphthalene biodegradation in seawater (0.5-15ºC)
(Masteroppgave/UIS-TN-IMN/2009, Master thesis, 2009)The polar areas are very vulnerable to exposure to contaminants. An oil spill in polar areas could be a disaster to large areas. The recovery from contamination takes longer time in arctic areas than in more temperate areas ... -
Texture and sensory properties of modified fish products for dysphagia patients
(Masteroppgave/UIS-TN-IMN/2018;, Master thesis, 2018-12)The Statistics Norway (SSB) population projection indicates that the people aged 70 years and above will double in three decades, from nearly 600,000 today to around 1.2 million. During ageing, many elderly people undergo ... -
Texture measurements of protein enriched foods for elderly.
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-06-15)Elderly people require nutritious food with a high protein content in their diet, and at the same time the food should be attractive and easy to swallow. A good diet not only helps in protecting the health but it also ... -
The challenge of preparing plasma free tyrosine and 3-nitrotyrosine for GC/MS analysis
(Masteroppgave/UIS-TN-IMN/2015;, Master thesis, 2015-06-12)3-Nitrotyrosine and the 3-nitrotyrosine/tyrosine ratio has been acknowledged as a biomarker of nitro-oxidative stress and its elevated level in biological fluids is associated with a wide range of clinical conditions. ... -
The chemo-mechanical effects of carbonated water at realistic reservoir conditions
(Masteroppgave/UIS-TN-IMN/2014;, Master thesis, 2014-03-19)The possibility of CO2 capture coupled with sequestration in deep geological formation has emerged in attempt to reduce the significant increase of CO2 (g) in the atmosphere. The impact of CO2 on the reservoir integrity ... -
