1. 1. Norra polcirkelns uppvärmning och ännu varmare maktkapplöpning

   Kandidat-uppsats, Lunds universitet/Statsvetenskapliga institutionen

   Författare :Ulf Liljedahl; [2024]
   Nyckelord :Klimatförändringar; Arktis; Geopolitik; Internationella relationer; Realism; Liberalism; The Arctic five; Law and Political Science;

   Sammanfattning : Today the climate in the arctic regions are changing at a rapid rate, faster than any speed previously recorded in human history but how is it impacting the geopolitical situation in these regions? New territory is being created by the ice melting and new natural resources are being found, how can this impact the current situation? This study looks at and discusses the current geopolitical situation in the Arctic using two theories from international relations, realism and liberalism and how the situation can develop using these theories. From a realist standpoint it is a balance of power held in check primarily by nuclear weapons. LÄS MER

3. 2. Drivers of sea level variability using neural networks

   Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

   Författare :Linn Carlstedt; [2023-05-10]
   Nyckelord :;

   Sammanfattning : Understanding the forcing of regional sea level variability is crucial as many people all over the world live along the coasts and are endangered by extreme sea levels and the global sea level rise. The adding of fresh water into the oceans due to melting of the Earth’s land ice together with thermosteric changes has led to a rise of the global mean sea level with an accelerating rate during the twentieth century.

4. 3. Modelling the chemical recycling of plastic waste via pyrolysis and analysing integration with existing refinery infrastructure

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Simon Dahl; [2023]
   Nyckelord :Pyrolysis; Recycling; Integration; Modelling; Simulation; Techno-economic; Plastic; Chemical engineering; Technology and Engineering;

   Sammanfattning : Current plastic management is unsustainable as large amounts of plastic end up landfilled or in the ocean, necessitating an expansion of waste management infrastructure. Pyrolysis is a viable chemical recycling option, and in this report a pyrolysis model is constructed in Aspen Plus. LÄS MER

5. 4. Platsens betydelse för växtnäringsläckage från jordbruksmark i Sverige

   Kandidat-uppsats, SLU/Dept. of Soil and Environment

   Författare :Frida Lundell; [2023]
   Nyckelord :kväve- och fosforutlakning; rumslig variation; långtidsövervakning;

   Sammanfattning : Växtnäringsläckage av kväve (N) och fosfor (P) från jordbruksmark tillför näringsämnen till hav och vattendrag. Det är viktigt att minska transporten av N och P av flera anledningar, då det bland annat är en stor bidragande faktor till övergödning. LÄS MER

7. 5. Arktis, en plats för både soft och hard power?

   Kandidat-uppsats, Lunds universitet/Statsvetenskapliga institutionen

   Författare :Ida Molin; [2023]
   Nyckelord :Arktis; Kina; Ryssland; soft power; hard power; Nordostpassagen; Law and Political Science;

   Sammanfattning : The Arctic is a changing place where the melting of the ice creates new opportunities and shipping lanes, such as Northern Sea Route and possibility for raw material extraction. However, this prospects can also be a road to conflict. LÄS MER
