1. 6. Satellite signal attenuation due to atmospheric influences in northern Sweden

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

   Författare :Adrian Stigsson; [2024]
   Nyckelord :;

   Sammanfattning : Earth-space traversing electromagnetic waves become attenuated as they propagate through the atmosphere. The sources of attenuation are weather phenomena in the Troposphere, and scintillation and absorption in the Ionosphere. LÄS MER

3. 7. The Arctic in Transition : Great Power Competition at the End of the Post-Cold War Order

   Master-uppsats, Försvarshögskolan

   Författare :Malin Ridström; [2024]
   Nyckelord :the Arctic; Russia; China; the United States; great power behaviour; offensive realism; defensive realism; power transition theory; grand strategy; qualitative content analysis; Arctic exceptionalism;

   Sammanfattning : This study uses defensive realism, offensive realism and power transition theory (PTT) in order to examine the great powers’ grand strategies in the Arctic region, aiming to recontextualise the security theatre in the Arctic as a reflection of the return of great power politics and the end of Arctic exceptionalism, and to examine the explanatory power of the different strands of realism on the great power behaviour identified in their Arctic strategies. The study is conducted using qualitative content analysis and utilises Jacob Westberg’s theorisation of grand strategies through the categories of context, ends, means and ways as analytical framework, to which the theoretical framework is applied.

4. 8. The bzzzt of frirends. Interspecific competition in Arctic plants for pollination services.

   Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Författare :Malin Olsson; [2023-06-27]
   Nyckelord :the Arctic; pollinator networks; competition; autonomous selfing; Arktis; pollinationsnätverk; konkurrens; autonom självpollinering;

   Sammanfattning : The Arctic has a harsh environment that is challenging for the flora and fauna that inhabits the region. The ruling abiotic factors of the region results is a low species richness that creates a potential challenge for the region’s plant species. LÄS MER

5. 9. Trends in mountain birch seed abundance and its relation to temperature and moth abundance: a ten-year study from Swedish Lapland

   Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

   Författare :Frida Gustafsson; [2023-02-09]
   Nyckelord :Betula pubescens; climate change; seed production; Epirrita autumnata; Operophtera brumata; subarctic ecology; folivory; larval abundance;

   Sammanfattning : Boreal forest is the world’s largest terrestrial biome. Being one of the most ubiquitous and coldtolerant tree species in Sweden, the mountain birch forms a unique deciduous treeline and marks the forest-tundra ecotone. LÄS MER

7. 10. The implications of heavy fuel oil ban in arctic waters for sustainable arctic shipping

   Master-uppsats, Göteborgs universitet/Institutionen för marina vetenskaper

   Författare :Kaung Thu; [2023-01-23]
   Nyckelord :Arctic region; heavy fuel oil; shipping; Sustainable;

   Sammanfattning : The increased temperature in the polar regions is one of the significant impacts of global warming and consequential climate change. In the Arctic, regional warming leads to the accelerated loss of sea ice caps, which has opened up new international shipping routes. LÄS MER
