11. Thermal response tests : influence of convective flow in groundwater filled borehole heat exchanger
Sammanfattning : The main objective of this doctorial thesis was to investigate how thermally induced movements in the groundwater (natural convective flow) may influence the heat transport in borehole and surrounding bedrock in a groundwater filled borehole heat exchanger system. The purpose was also to determine if thermal response tests could be used to detect the convective influence and the effect on evaluated heat transfer parameters, effective bedrock thermal conductivity and borehole thermal resistance.

12. Recycling of CIGS solar cell waste materials
Sammanfattning : The increased interest in solar power over the last few decades has led to a constant development of existing and new types of solar cells. One type of solar cell that is making advances on the global market is copper indium gallium diselenide (CIGS) thin film solar cells. LÄS MER
13. Recycling of selenium from CIGS solar cell materials
Sammanfattning : Today the importance of solar cells as a power source is growing due to the environmental advantages compared to fossil fuels. One of the most promising new solar cell materials, resulting in high efficiency solar cells, is copper indium gallium selenide (CIGS). LÄS MER
14. Pamfletter! : En diskursiv praktik och dess strategier i tidig svensk politisk offentlighet
Sammanfattning : This thesis discusses argumentative strategies for legitimation and delegitimation in political pamphlets published in 1769 and in 1809–1810, each period representing the onset of democracy and freedom of the press. The aim of the study is twofold. LÄS MER
15. Cancer Genomics - Molecular Analysis of Epithelial Cells
Sammanfattning : Cancer is a disease involving multiple causal andsymptomatic genetic changes, collectively reflecting theselective pressures that occur during tumor development.Epithelial cancers are by far the most common type of cancerworldwide and investigation of the alterations associated withepithelial carcinogenesis will ultimately lead to improvementsin diagnosis, prognosis, prevention and treatment of thedisease.
