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, ... -
Abundance of functional groups of nitrogen transforming microorganisms potentially involved in N2O emissions from a subtropical forested watershed in China.
(Master thesis, 2015-03-16)In this study, we investigated N-cycling processes and N2O emissions along a hillslope (HS) and a hydrologically connected groundwater discharge zone (GDZ) in a subtropical forest ecosystem in southwest China, Tieshanping ... -
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 ... -
Acute toxicity effect of amines in a nitrifying process
(Master thesis, 2012-10-16)The longest continuous record of atmospheric CO2 is found at the Mauna Loa observatory in Hawaii. Looking at the overall scenario the measurements show a steady increase in mean atmospheric CO2 concentration from about 315 ... -
Adipocytter, makrofager og inflammasjon : en in vitro studie
(Master thesis, 2012-09-12)Fedme er den vanligste årsaken til insulinresistens og en rekke andre metabolske forstyrrelser, som til sammen utgjør det vi kaller metabolsk syndrom. Et kjennetegn ved fedme og utvikling av metabolsk syndrom er en svak, ... -
Adsorpsjon av lignosulfonater på leire og kull : modellstudie for økt forståelse av rollen i CIL/CIP prosesser.
(Master thesis, 2012-05-21)Lignosulfonater, sulfonert lignin, produseres som et biprodukt gjennom sulfittprosessen i produksjonen av cellulose eller ved å sulfonere Kraft lignin. Produktet har gode egenskaper som dispergeringsmiddel og bindemiddel, ... -
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 ... -
Age pigment dynamics in worker-honeybees ( Apis Mellifera )
(Master thesis, 2013-08-27)Growing old is often related to a decline in physiological function, performance, survival or reproduction.(Kirkwood 2002) But studies among animals have showed that an increased chronological age doesn’t automatically ... -
A GLI1 Oncogene Induced Model of Breast Cancer

Aktiveringsparamtere for det kitinolytiske maskineriet til Serratia marcescens
(Master thesis, 2013-08-26)Denne studien har tatt utgangspunkt i enzymatisk hydrolyse av det uløselige substratet kitin. Hovedmålet har vært å bestemme aktiveringsparametre for denne reaksjonen og bruke disse som et mål på endoaktivitet. Videre har ... -
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 ... -
Analyse av TAG, DAG, og MAG i fordøyd kumelk ved off-line SPE-SPE og GC-MS
(Master thesis, 2015-02-25)Melk og fermenterte meieriprodukter fra ulike dyr har i flere tusen år blitt brukt som human næringskilde. Fettinnholdet i kumelk er 3-4 g/100 g, hvor omtrent 95-98 % er i form av triglyserider. Resten er små mengder ... -
