Optimalization of synthesis of FAME, FAEE, FAPE and FABE for analysis with GC-FID and GC-Orbitrap
(Master thesis, 2022)Fatty acids are an important part of our diet and is mainly consumed in the form of fat. The most widely used technique for analysis of FA composition is by GC-FID and GC-MS. To analyse a FA profile, it is necessary to ... -
Optimalt fôr som gir fast filet
(Nofima rapportserie;, Research report, 2010)Formålet med studien var å undersøke om fôr tilsatt aminosyrene arginin eller glutamat kan forbedre teksturen av oppdrettslaks. I tillegg ønsket vi å undersøke om bløt filet kan knyttes til nedsatt leverfunksjon eller andre ... -
Optimering og simulering av solceller lagt på duk
(Master thesis, 2017)Formålet med denne oppgaven var å optimalisere og simulere et solenergisystem lagt på duk og å undersøke systemets potensial. Optimaliseringen ble utgangspunkt for bygging av et industritelt, med solceller på taket, som ... -
Optimisation of nucleic acid extraction methods for a low pH soil, quantification of denitrification gene expression, and the analysis of gas kinetics from agricultural peat soils
(Master thesis, 2013-09-10)Denitrification is one of the main processes in the nitrogen cycle, and it is the reduction of nitrate to N2 through a series of intermediates, removing biologically available nitrate from the biosphere. NO and N2O are ... -
Optimisation of the coagulation process to improve plant availability of phosphorus in wastewater sludge
(PhD Thesis;2016:61, Doctoral thesis, 2016)Coagulation is used for the removal of colloids, particles and phosphates in wastewater treatment. The efficiency and economics of chemical coagulation, one of the most robust wastewater treatment processes, is critically ... -
Optimisation of thermal processing of fresh farmed cod
(PhD Thesis;2011:17, Doctoral thesis, 2011)Heat treatment of cold water species is challenging due to quality changes occurring at low temperatures relative to most other foodstuffs. One of the characteristic challenges is the melting of connective tissue already ... -
Optimisation of wastewater treatment systems with data mining and process modelling
(PhD Thesis;2018:43, Doctoral thesis, 2018)Wastewater treatment facilities serve an important purpose in public sanitation. Wastewater treatment plants (WWTP) are built at the end of sewerage systems to purify the wastewater before it enters natural water bodies. ... -
Optimising anaerobic digestion of manure resources at a regional level
(Journal article; Peer reviewed, 2018)An optimisation model was developed to give decision support on methods of managing manure resources within a region to reduce greenhouse gases and at the same time obtain economic profitability for the farmer. The model ... -
Optimising maintenance operations in photovoltaic solar plants using data analysis for predictive maintenance
(Master thesis, 2022)In PV (photovoltaic) solar power plants, high reliability of critical assets must be ensured— these include inverters, which combine the power from multiple solar cell modules. While avoiding unexpected failures and downtime, ... -
Optimising nanoporous supercapacitors for heat-to-electricity conversion
(Journal article; Peer reviewed, 2022) -
Optimising the Extraction and Quantification of Geosmin and 2-Methylisoborneol by Use of LLE, SPE and GC Orbitrap
(Master thesis, 2023)Water is an incredibly valuable resource to humans. Concerns for distasteful contaminants in water sources emerged in the 70’s and has been observed to cause significant losses of water resources in recent years. Geosmin ... -
Optimising the utilisation of agricultural manure for biogas production : a model based on the county of Vestfold in Norway
(Master thesis, 2017)The threat of climate-change and the harm it is doing to the Earth has been known for a long time, and the worlds countries have come together to try to limit the damages humanity is doing. The result is multiple international ... -
Optimization and assessment of Omega-3 fatty acids from high-dimensional spectroscopic data in the Atlantic salmon breeding programs
(Master thesis, 2023)Atlantic salmon is well known as a rich source of Omega-3 fatty acids (in particular, ALA, DHA, and EPA), and these fatty acids are heritable, thus, the selection of parents will influence their levels in the offspring. ... -
Optimization of a genotyping scheme for Treponema pallidum subsp. pallidum including markers for macrolide resistance
(Master thesis, 2023)Syfilis er en seksuelt overførbar infeksjon, og er et viktig folkehelseproblem både i Norge og i verden. Forekomst av syfilis har økt i de senere årene, spesielt blant menn som har sex med menn (MSM). Bakterien Treponema ... -
