1. 1. Infiltration, hydrogeology, and heterogeneity - Management of pressure and flow: A case study for the Varberg tunnel project

   Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

   Författare :Lisa Risby; [2020-07-08]
   Nyckelord :short duration hydraulic tests; hydraulic conductivity; radius of influence; infiltration; heterogeneity; confined and unconfined aquifer;

   Sammanfattning : This thesis aims to describe a conceptual model of the sedimentology for Swedish (or nordic)conditions of heterogeneous aquifers but focus is on a case study in Varberg. This to facilitatethe identification of main water-bearing units (e.g. LÄS MER

3. 2. Foucault, Fairclough och järnrörets diskursordning : En kritisk diskursanalys av maktförhållandet mellan representanter ur riksdagspartiet Sverigedemokraterna och kvällstidningen Expressen under den så kallade "Järnrörsskandalen"

   Kandidat-uppsats, Högskolan i Gävle/Media- och kommunikationsvetenskap

   Författare :Isak Storm; [2020]
   Nyckelord :Discourse; power; hegemony; exclusionary mechanisms; order of discourse; Diskurs; makt; hegemoni; utestängningsmekanismer; diskursordning;

   Sammanfattning : Denna studie är en kritisk diskursanalys av tidningen Expressens artikelserie kring "Järnrörsskandalen" med särskilt fokus riktat kring hur Faircloughs tredimensionella analysmodell kan användas för att undersöka olika diskursordningar. Foucaults teori kring utestängningsmekanismer utgör även en betydande del av analysunderlaget och påvisar det komplexa förhållandet kring att försöka påvisa diskursens konstanta föränderlighet.

4. 3. Do feed-in tariffs promote environmental efficiency among wind farms? : a two-stage LCA + DEA efficiency case study on 75 Danish wind farms

   Master-uppsats, SLU/Dept. of Economics

   Författare :Gustav Berglöf; [2020]
   Nyckelord :DEA; efficiency; environmental efficiency; feed-in tariff; operational efficiency; renewable energy; subsidy; wind power;

   Sammanfattning : It is generally known that wind power has an offsetting effect on emissions by crowding out fossil dependent energy sources. What has not been studied to any further extent is the variability in environmental impacts caused by wind turbine erection and manufacturing. Also, it is not known how economic incentives could affect these impacts. LÄS MER

5. 4. Modelling gross primary production in semi-arid regions: effects on carbon uptake of intensive agriculture in southern Kenya

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Malin Ahlbäck; [2020]
   Nyckelord :Physical Geography; Ecosystem Analysis; GPP; Africa; Kenya; Land cover changes; Cropland; Remote sensing; Sentinel-2; Earth and Environmental Sciences;

   Sammanfattning : Background and aim: Gross primary production (GPP) is the largest global carbon (C) flux and an important component for counteracting anthropogenic CO2 emissions, understanding vegetation dynamics, and sustaining universal human standards. Africa plays a prominent role in the global C cycle, though our understanding of GPP dynamics is largely hampered by a paucity of ground-based observations. LÄS MER

7. 5. A pragmatic approach to improve the efficiency of the waste management system in Stockholm through the use of Big Data, Heuristics and open source VRP solvers : A real life waste collection problem;Stockholm’s waste collection system and inherent vehicle routing problem, VRP

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Rafael Salcedo Villanueva; [2020]
   Nyckelord :;

   Sammanfattning : In this thesis, we will address a real life waste collection problem; Stockholm’s waste collection system and inherent vehicle routing problem, VRP. To do this we will first delve into some mathematical theory of Combinatorial Optimization and Heuristics to understand the fundamentals of the problem. LÄS MER
