Performance evaluation of water and wastewater treatment plant in Kathmandu Valley
(Master thesis, 2016-11-17)In this work, assessments of technology of the water and wastewater treatment plants including constructed wetlands in Kathmandu valley are presented. There are nine water treatment plants among which two are not in ... -
Performance of a photovoltaic-thermal system in a tropical environment of central Ghana
(PhD Thesis;2022:14, Doctoral thesis, 2022)Access to energy has been heavily linked to socio-economic development. It is therefore not surprising that the energy poverty in sub-Saharan Africa has affected development in the subregion. However, as development ... -
Personality differences among domestic cats (Felis catus) in Norway and how they affect home range size
(Master thesis, 2021)Research on animal personalities has greatly increased in the last few decades, revealing it as an influential contribution to survival and space utilisation. Domestic cats pose a risk to wildlife through disease transmission ... -
Phenolic defense mechanisms in needles of nursery plants and naturally regenerated Norway spruce (Picea abies)
(Master thesis, 2022)To incorporate sustainable management in increasing forestry practices in Norway, low impact management of Pine weevils (Hylobius abietis), the most common pest on clear cut area in boreal silviculture, is of great importance. ... -
Phenology, growth and metabolism of two northern deciduous tree species in relation to temperature and light conditions
(PhD Thesis;2016:33, Doctoral thesis, 2020-11-19)In temperate climates, phenological transitions in tree species allow survival through adverse climatic conditions in winter. Seasonal change is sensed through shifting patterns in daylength, temperature and light quality. ... -
Phosphorus from sludge : evaluation of organic polymer substitution of metal coagulants on phosphorus availability for plant uptake
(Master thesis, 2016-08-11)Majority of Norwegian wastewater treatment plants utilize chemical treatments such as coagulation to meet high removal standards for phosphorus in wastewater. Up to 85% of the total sludge produced from these plants are ... -
Phosphorus recovery through struvite precipitation: testing of parameters which enhance phosphorus recovery
(Master thesis, 2017)Phosphorus is an essential nutrient for growth in all living organisms and is used as fertilizer to maintain food production. Today's recovery of mineral phosphate will lead to a lack of phos-phorus as mineral fertilizer ... -
Phosphorus Removal from Wastewater through Struvite Precipitation
(Master thesis, 2017)Phosphorus is an essential nutrient to sustain life. With regards to limited Phosphorus resources, recovery and reuse of Phosphorus are necessary. Wastewater usually contains large amount of Phosphorus which could cause ... -
Phylogenetic diversity and evolutionary distinctiveness of Amazonian floodplain forest birds
(Master thesis, 2022)The Amazon basin contains one-fifth of all free-flowing fresh water on the planet and is home to the largest tropical rainforest on Earth. However, the region is not homogenous and is interspersed with several different ... -
Phytoplankton in humic and colored Nordic lakes
(MINA fagrapport;66, Report, 2020)Concentrations of lake dissolved organic carbon (DOC) transported from catchments, with simultaneous browning, are currently increasing in boreal lakes, and predicted to continue in the future. This increased load of organic ... -
Planlegging av restaureringstiltak for pollinatorer fra et landskapsøkologisk perspektiv
(Master thesis, 2023)Verdens biomangfold har lidd drastiske tap det siste århundret. Hovedgrunnen til denne negative utviklingen er tap av habitat, hvor store deler av tapet skyldes overgang til et mer intensivt jordbruk. Restaurering av ... -
Plant Response to Biochar Augmented Soils from Different Biogeographic Regions
(Master thesis, 2012-11-14)The objective of this study is to use plant phytometers to test whether biochar amendment increases soil fertility. The phytometric method has the asset of measuring the actual effect of biochar ... -
Plant-plant interactions do not result in reproductive costs for Silene acaulis across an elevational gradient at Finse, Norway
(Master thesis, 2023)Plants interact negatively with each other through competition for space, light, or belowground resources, resulting in a reduction in individual survival, growth, or reproduction. Facilitation, on the other hand, is a ... -
Plantekvalitet og etableringsevne hos toårige planter av gran (Picea abies)
(Master thesis, 2017)Foryngelse er det første og viktigste steget etter hogst for å sikre bærekraftig bruk og utnyttelse av skogressursene. Gran (Picea abies) utgjør omtrent halvparten av stående volum i norsk skog og forynges i hovedsak gjennom ... -
Plastic waste management in refugee camps : a case study from the Somali region in Ethiopia
(Master thesis, 2019)Sustainable waste management is something that has only been studied and developed in a few refugee camps in the world. This thesis, and the project it has been written through, aims to improve the waste management system ... -
Pollination Efficiency of Native Bees and Honeybees to Apple in Norway
(Master thesis, 2023)Crop pollination is traditionally managed with the European honeybee (Apis mellifera). However, the supply of honeybees may not be sufficient to meet the increasing global pollination demands and beekeepers are met with ... -
Population estimate, trend and habitat preferences of breeding curlews (Numenius arquata) in Akershus, southeast Norway
(Master thesis, 2018)The Eurasian Curlew (Numenius arquata) is a species in decline, classified as near threatened (NT) worldwide, and vulnerable (VU) in Norway. In the region of Akershus (SE Norway), no recent update exists of the breeding ... -
Population monitoring of Great Crested newts in a developmental area – use of ventral side photography and automatic image recognition
(Master thesis, 2023)1. Amphibian species all over the world are in a decline due to climate change as well as human activities. To mitigate negative impacts on amphibians, especially in urban development areas, it is important to understand ... -
Post-fledging parental care in the female great grey owl (Strix nebulosa) : a trade-off between provisioning and guarding
(Master thesis, 2018)Post-fledging parental care is generally little studied in birds. By use of radio telemetry, I studied the post-fledging parental behaviour of female great grey owls (Strix nebulosa), measured as number of prey deliveries ... -
