Determining the Cell Size of Yeast Using Diffusion-Weighted NMR
(The University of Bergen, 2019-11-16)Abstract This study uses diffusion weighted NMR to determine yeast cell size at different times after those cells were suspended in water. Both the water diffusion and the metabolite diffusion where used in those measurements. ...Master thesis -
Characterizing mass transport in hydrogels using Nuclear Magnetic Resonance
(The University of Bergen, 2019-11-08)During the past decades, drug delivery system has become an important research topic in the pharmaceutical field. Conventionally, the therapeutic concentration of a drug in the blood is achieved by repeated administration ...Doctoral thesis -
Interpretation of multivariate association patterns between multicollinear physical activity accelerometry data and cardiometabolic health in children-a tutorial
(MDPI, 2019-07-02)Associations between multicollinear accelerometry-derived physical activity (PA) data and cardiometabolic health in children needs to be analyzed using an approach that can handle collinearity among the explanatory ...Journal article -
Towards the Synthesis of β-Hydroxy 1,3-Dithiane Derivatives
(The University of Bergen, 2019-10-03)The β-hydroxy dithiane, 3-(1,3-dithiane-2-yl)-1,1-diethoxypropan-2-ol, was synthesized from the versatile synthon 3,3,4,4-tetraethoxybut-1-yne (TEB). 1,1-Diethoxy-3-(2-methyl-1,3- dithian-2-yl)propan-2-ol was successfully ...Master thesis -
Development of methods based on NIR and Raman spectroscopies together with chemometric tools for the qualitative and quantitative analysis of gasoline
(The University of Bergen, 2019-09-28)Gasoline quality control is essential for SI engines performance and to reduce environmental impacts by generation of undesirable pollutants. Methods established by the American Society for Test and Materials (ASTM) are ...Master thesis -
Analysis of Fatty Acids by High Performance Liquid Chromatography and Electrospray Ionization-Mass Spectrometry
(The University of Bergen, 2019-09-28)Fatty acids (FA) have been traditionally analyzed by gas chromatography (GC) as fatty acids methyl esters (FAME) and more recently using mass spectrometry (MS) detection. Since high performance liquid chromatography (HPLC) ...Master thesis -
Synthesis of substituted imidazoles that stabilizes Survival Motor Neuron Protein for treatment of Spinal Muscular Atrophy
(The University of Bergen, 2019-08-31)Spinal muscular atrophy (SMA) is a common autosomal recessive disorder and the leading cause of infant mortality. Patients with this disorder are missing the SMN1 gene that is producing 80-90 % of the Spinal motor neuron ...Master thesis -
Synthesis and characterization of synthetic and biopolymer hydrogels
(The University of Bergen, 2019-09-04)Hydrogels are widely researched for biomedical applications such as drug delivery. The tunable properties of hydrogels, in terms of swelling, mechanical properties and mesh size, make them prime candidates for this ...Master thesis -
