Sjølaksefiske : kultur, identitet og konflikt : et case studie av underliggende årsaker til konflikter om naturressurser
(Master thesis, 2019)Det har vært en nedgang i biologisk og kulturelt mangfold de siste tiårene og mye kunnskap om vår plass i naturen går tapt. Denne artikkelen ser på konflikter om naturressurser gjennom et case-studie av sjølaksefisket i ... -
Small Scale Wastewater Treatment System at Høyås Farm in Ås, Norway
(Master thesis, 2014-08-04)Phosphorus (P) removal in small scale wastewater treatment systems (SSWWTSs) to achieve P discharge limit of 1mg/l requires P filters with high P sorption capacity. For comparison purposes, two P filters are used at Høyås ... -
Soil carbon sequestration through rangeland management : soil carbon and nitrogen stocks and the management issues for enhancing soil carbon sequestration potential in rangelands of Gairo, Tanzania
(Master thesis, 2014-09-22)Rangelands are the unutilized lands which constitute 47% of the world land area containing very low SOC. Though they have very low tendency to store carbon, it can be enhanced by few management practices as these holds ... -
Soil quality and fertiliser application in Norwegian apple orchards
(Master thesis, 2019)Little research has been done on soil quality and fertilisation in fruit orchards in Norway in recent decades. This thesis investigates pH and nutrients in soil samples from 25 farms in the four main apple districts in ... -
Speciation and mobility of particle-associated radiocesium in soils and pond sediments from Fukushima, Japan
(Master thesis, 2018)The Fukushima Daiichi Nuclear Power Plant (FDNPP) accident that occurred in March 2011 at the nuclear facilities of units 1, 2 and 3 in Japan resulted in the release of radioactive cesium (137Cs) containing particles. In ... -
Speciation, uptake and toxic effects of Cadmium on developing stages of Atlantic salmon (Salmo salar)
(Master thesis, 2016)Cadmium (Cd) is well known as one very toxic trace elements for aquatic organisms including fish. Uptake and toxic effects of Cd in embryo of Atlantic salmon was studied from fertilization to hatching stage. Eggs from ... -
Survey of onsite wastewater treatment systems in Kristiansand municipality Norway : pollutants removal performance and solutions : performance analysis based on Web-GIS model
(Master thesis, 2017)In Norway, 16% of the population lives in rural areas where centralized infrastructure for wastewater treatment is neither cost effective and nor sustainable due to topography and long distance to connect a treatment ... -
Temporal and spatial GIS visualizations and statistics of near-term DOC changes in ten Norwegian lakes, based on the climatic factors precipitation and temperature
(Master thesis, 2016)The colour of lakes several places in the Northern hemisphere has been increasing the last few decades; this brownification is affecting aquatic life, drinking water facilities and the carbon cycle. It is closely linked ... -
Temporal changes in plant available phosphorus in a long term experiment growing winter wheat (Triticum aestivum) on Rothamsted, England
(Master thesis, 2016-08-11)Fosfor er eit næringsstoff naudsynt for alt liv, men det er ein avgrensa ressurs som på avvege kan føra til uynskja algeblømingar. Difor er det viktig med god fosforbruk i landbruket, der det kjem mykje mat frå den tilførde ... -
The combined effect of depleted uranium, sodium arsenite and gamma radiation on survival, growth and reproduction of Caenorhabditis Elegans
(Master thesis, 2017-03-31)The purpose of this work was to study the effect of depleted uranium, sodium arsenite and gamma radiation on three biological endpoints of Caenorhabditis Elegans. The three endpoints studied were survival, growth, and ... -
The effect of freezing and thawing on transport of pesticides through macroporous soils and the potential risk towards the aquatic environment
(Master thesis, 2017)Pesticides and their metabolites can leach rapidly through agricultural soils through macropores, be transported further into surface waters and potentially cause negative effects in aquatic organisms. Cold climate with ... -
The effect of proximity to forest on bee visit frequency to six plant species in an oil palm landscape in Borneo
(Master thesis, 2018)Pollination is critical for global food security as it ensures the reproduction of many wild and crop plants. Pollination services may be at risk as tropical rainforests are rapidly being destroyed and degraded, largely ... -
The effect of secondary metabolites, nutrients and invertebrates on fungal establishment and decomposition rates in European Aspen (Populus tremula)
(Master thesis, 2019)Fungal decomposer communities play an essential role in nutrient cycling and are one of the main drivers of decomposition. Although fungal community composition has been seen to influence the rate of wood decay, little is ... -
The effects on soil physical properties of long term soil tillage and soil compaction
(Master thesis, 2014-11-04)Soil degradation in crop production is becoming increasingly important because of the growing concern it poses on soil functions. Prominent among the degradation factors is soil compaction. It impairs soil productivity ... -
The environmental occurrence, fate, and behavior of airborne organic contaminants of emerging concern in Norwegian terrestrial ecosystems
(Master thesis, 2019)Airborne organic contaminants of emerging concern (AOCs) are a large assembly of organic compound groups. AOCs consist of legacy persistent organic pollutants (POPs) and new POP- like compounds. These compound groups are ... -
