Biological control of parasites on orange plantations : a predator prey model
(Master thesis, 2016-08-29)In this thesis, a four dimensional autonomous dynamical system, proposed as a model for biological control of a parasite on citrus plantations, is studied. The model is the same as that studied by Sotomayor et. al. in ... -
Biological control of salmon lice : a critical analysis of knowledge production and development in the Norwegian cleaner fish industry
(Master thesis, 2020)The lumpfish and four species of wrasse have become important resources for cleaning salmonids of sea lice in Norwegian aquaculture. Cleaner fish’s delousing effectiveness and mortality rates in salmon cages vary dramatically ... -
Biological control of the cabbage root fly (Delia radicum) using an entomopathogenic fungus (Metarhizium brunneum)
(Master thesis, 2020)Cabbage root flies are a damaging pest to cruciferous crops in the northern hemisphere. They are considered to be the main pest of brassica crops (EPPO, 2004). Their larvae feed on the roots and stems of brassica plants. ... -
Biological diversity of gound-dwelling beetles (Coleoptera): impact of frequent cutting of the tree layer
(Master thesis, 2012-09-07)Abstract Forestry is the main disturbance in forest ecosystems in Fennoscandia. Power-line corridors have some similarities with clear cuts created through modern forestry practices, but regrowth of vegetation is ... -
Biological effects of low dose radiation from the cobalt-60 source at Ås, Norway, and of natural background radiation at the thorium-rich area in Telemark, Norway : studies with the model plant Arabidiopsis Thaliana
(Master thesis, 2012-04-27)Several studies exist on radiation effects on organisms. Although most of the interest has been on humans, during the last few years increasing attention has been directed to other organisms, focusing on an ecosystem ... -
Biological Evaluations, NMR Analyses, Molecular Modeling Studies, and Overview of the Synthesis of the Marine Natural Product (−)-Mucosin
(Peer reviewed; Journal article, 2024)Natural products obtained from marine organisms continue to be a rich source of novel structural architecture and of importance in drug discovery, medicine, and health. However, the success of such endeavors depends on the ... -
Biological vs. chemical regulation of nitrite concentrations in acidic and neutral pH soils : a study of kinetics and bacterial denitrifier communities
(Master thesis, 2015-11-06)Denitrification is an anaerobic microbial respiratory process, which takes part in the global biogeochem- ical nitrogen cycle. Microbial denitrifiers contribute to the global recirculation of nitrogen, by stepwise reduction ... -

Biologiske og tekniske prinsipp ved lågtrykkslagring av grønsaker
(Professional article, 1979)Etter det eg kjenner til er det ikkje arbeidd med lågtrykkslagring av friske planteprodukt her i landet. Av den grunn rekner eg med at det kjennskap dei fleste her har til denne lagringsmetoden er heller perifert. Eg har ... -
Biology and control of the invasive Fallopia taxa
(Master thesis, 2015-05-07)Abstract Fallopia japonica and Fallopia sachalinensis are perennial, rhizomatous plants, native to East Asia, and introduced to Europe in the mid 1800’s. Hybridization between the taxa in the introduced range has given ... -
Biomagnification and bioaccumulation to "at risk levels" in the humic lake Øvre Sandvannet, SE Norway
(Master thesis, 2013-09-24)In recent years, the concentrations of mercury (Hg) in game fish from South East Norway have increased, while, simultaneously, the depositions of Hg in precipitation have shown a decreasing trend. This apparent discrepancy ... -
Biomarkers of stress and exercise-induced affect in connection with physical activity in nature
(Master thesis, 2014-08-21)Psychosocial stressors can contribute to chronically stimulate the stress-response system, possibly leading to disease if not adequately “shut off”. Physical activity in nature, called green exercise, is often used a means ... -
