Mimicking orchids lure bees from afar with exaggerated ultraviolet signals
(Peer reviewed; Journal article, 2023-01)Flowers have many traits to appeal to pollinators, including ultraviolet (UV) absorbing markings, which are well-known for attracting bees at close proximity (e.g., <1 m). While striking UV signals have been thought to ... -
Model based optimization of biogas production at SNJ plant
(Masteroppgave/UIS-TN-IMN/2010;, Master thesis, 2010)The main purpose of this thesis is the acquisition of knowledge and familiarization with the SNJ biogas plant and effects of codigestion. Plant operation and performance was monitored in order to understand and evaluate ... -
A modelling study of environmental fate and effects of oil leakage from abandoned wells
(Masteroppgave/UIS-TN-IKBM/2019;, Master thesis, 2019-06-15)Potential environmental consequences of oil leakages are taken into consideration in the ongoing development of plug and abandonment (P&A) activities on the Norwegian Continental Shelf (NCS). The P&A on the NCS has been ... -
Molecular characterization of circulating tumor cells from pancreatic cancer patients by single-cell quantitative reverse transcription PCR
(Masteroppgave/UIS-TN-IMN/2014;, Master thesis, 2014-06-16)Pancreatic cancer is a highly lethal disease, which kills approximately 70 000 people per year in Europe alone. The median survival after the time of diagnosis is five to six months for patients with advanced cancer, making ... -
Molecular characterization of extended-spectrum beta lactamase producing Klebsiella pneumoniae from the Stavanger region between 2003 and 2012
(Masteroppgave/UIS-TN-IMN/2015;, Master thesis, 2015-06-12)Klebsiella pneumoniae is a Gram-negative rod in the Enterobacteriaceae family, known to cause both community- and hospital-acquired infections, especially in immunocompromised patients. In the hospital setting, K. pneumoniae ... -
