A Bayesian method for estimating moose (Alces alces) population size based on hunter observations and killed at age data
(Master thesis, 2013-09-09)Lots of wild species, fish and mammals, are heavy harvested through fishing and hunting. Reliable population size estimates are valuable management tools for these species. In cases where killed at age data are available, ... -
A comparative analysis of lactic acid bacteria isolated from honeybee gut and flowers, with focus on phylogeny and plasmid profiling
(Master thesis, 2016-08-10)Apis mellifera (honeybee) are of huge value as they are the most important pollinator worldwide. Declines in honeybee populations have made the honeybee subject to much scientific research. Lactic acid bacteria (LAB) have ... -
A comparative analysis on phylogeny, genetics and selected phenotypes of lactic acid bacteria isolated from gut microbiota of honey bee versus flowers
(Master thesis, 2016-08-10)From the bee gut samples 190 bacteria isolates were obtained. Purified plasmid DNA extracts were screened for plasmids on an agarose gel by electrophoresis to determine their plasmid profiles. The purpose of the plasmid ... -
A comparison of the effect of selected lactic acid bacteria on cytokine secretion from monocytes and macrophages in vitro
(Master thesis, 2012-10-03)Lactic acid bacteria (LAB) are commonly ingested with many types of food. Some strains have been shown to have beneficial health effects when ingested, of which a few have been given the term “probiotic”. Probiotics are ... -
A detailed study of substrate positioning in family 18 chitinases
(PhD Thesis;2011:41, Doctoral thesis, 2011)Chitin is a linear polymer consisting of β-1,4-linked N-acetyl-glucosamine (GlcNAc; A) units tightly packed in a crystalline structure. It is produced by living organisms in large quantities per year and is a structural ... -
A functional study of the essential amidotransferase complex MurT/CobQ in Streptococcus pneumoniae
(Master thesis, 2015-08-06)The bacterial cell wall is responsible for maintaining cell shape and gives protection from osmotic lysis caused by turgor pressure. The major component of the cell wall in Gram-positive bacteria is the structurally complex ... -

A multiplexed antibody-based approach for analysis of denatured cellular proteins : development of western-MAP
(Master thesis, 2013-09-23)This thesis describes a new method for multiplexed analysis of cellular proteins. The cellular proteins were biotinylated and fractionated by gel-electrophoresis using a device (Gelfree 8100), which yields liquid fractions ... -
A new method for the synthesis of fatty acid amides
(Master thesis, 2018)The amide bond is an essential part of many natural products and is also found in a lot of today’s pharmaceuticals. The fatty acid amides are a group of natural products that has shown biological activity towards several ... -
A novel pig cell line as model system for calcineurin inhibitors
(Master thesis, 2015-03-17)Organtransplantasjon kan være nødvendig i situasjoner med organsvikt som følge av sykdom eller skade. Det totale antallet transplantasjoner øker, og transplantasjoner ansees fortsatt som utfordrende. Høy kongruens av ... -
A penicillin resistant Streptococcus pneumoniae in the making : characterizing resistance development and cell fitness after acquiring low-affinity penicillin-binding proteins and a mosaic MurM
(Master thesis, 2019)Streptococcus pneumoniae is an important human pathogen, causing about 100 millions of cases of disease and 1 – 2 million deaths every year. The rapid evolution and spread of multiresistant strains threaten current antibiotic ... -
A quantitative analysis of organochlorine pesticides in Svalbard reindeer (Rangifer tarandus platyrhynchus)
(Master thesis, 2015-02-27)This study is a quantitative analysis targeting levels of selected organochlorine pesticides (OCP) located in muscle, liver, and fat of Svalbard reindeer (Rangifer tarandus platyrhynchus) in Svalbard (61 022 km2, 74-81°N, ... -
A simulation study : hierarchical PLS for multi-group classification
(Master thesis, 2015-08-05)Hierarchically Ordered Taxonomic Partial Least Squares (Hot PLS) is a method for classifying data in a hierarchical structure. Since Hot PLS is a relatively new method, we want to study strengths and weaknesses of this. ... -
A statistical analysis of the treatment effects of Traditional Chinese Medicine (TCM) in various health problems
