16. Hg concentration in humus soils in different Arctic and Subarctic tundra vegetation types : Including a method comparison for analyzing metals in humus soils
Kandidat-uppsats,Sammanfattning : Heavy metals, such as mercury (Hg), have a long residence time in the atmosphere and can be transported long distances and deposited in the Arctic via wet and dry deposition. Still, there are few studies on the complex mercury cycle and how different plant groups absorb Hg. LÄS MER
17. An Initial Analysis of Slurry Transportation in Subarctic Environment
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : In today’s economy, it is important to have a sustainable business model where as little as possible goes to waste or finding solutions to create something useful out of by-products. Therefore, LKAB are looking to make a large investment into creating an infrastructure of several plants to turn tailings from the production of iron ore into usable products for several industries which LKAB has designated project ReeMAP (Rear Earth Elements and MonoAmmonium Phosphate).

18. Viktiga funktioner och designfaktorer i resecentrum : Klimatanpassningar för subarktiskt klimat
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Arkitektur och vattenSammanfattning : I Sverige finns en enighet om att kollektivtrafiken måste utvecklas om målsättningar för klimat och attraktiva städer ska kunna nås. Trafiksystemets utformning har i sin helhet stor betydelse för en långsiktigt hållbar utveckling. Resecentrumen håller på att få en allt viktigare roll i stora som små städer. LÄS MER
19. Identifying subarctic river thermal and mechanical ice break-up using seismic sensing
Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : River-ice break-up in high-latitude regions, despite its brevity, is a fundamental process, representing the most dynamic and complex period of fluvial processes. Moreover, ice break-up has significant cascading ecological effects, with a different severity for mechanical vs. LÄS MER
20. Impact of fire and frost drought events on vegetation greenness and albedo in Subarctic Scandinavia
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : With climate change, the frequency in climate extremes such as drought, heavy rainfalls, and extreme temperatures is predicted to increase. These extremes can potentially stress and damage vegetation over large areas, leading to altered carbon cycle, vegetation greenness, albedo, and shifted species composition. LÄS MER
