1. Decay Chains of Fast Alpha Emitters in the Actinide Region
Magister-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysikSammanfattning : With the advent of increasingly advanced spectroscopic instruments after the turn of the century, it has become accessible to unravel the structure of instantly ‘vanishing’ nuclei, with lifetimes as short as 1 μs, and responsible for pile-up events in analog electronics. Experimental data has been recorded by the Nuclear Structure Group at Lund University for 48Ca/50Ti + nat. LÄS MER
2. Climate Change Coverage and the Performance of Green and Brown Equities
Master-uppsats, Lunds universitet/Nationalekonomiska institutionenSammanfattning : Climate change has emerged as one of the world’s most pressing issues, a development that has prompted investors to shift their focus accordingly, catalysing a significant increase in green investments. This study is set against this backdrop, focusing on the performance of portfolios of European firms classified as low or high emission intensity – green or brown respectively – during an eight-year period, from January 2010 to June 2018.

3. Calibration and preparation of the data analysis of the DORN experiment on board the Chang'E 6 lunar mission.
Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknikSammanfattning : As part of the first agreement between the French (CNES) and the Chinese (CNSA) space agencies in terms of space exploration, the DORN instrument will fly on board the Chinese Chang'E 6 mission in 2024. It aims to measure the amount of Radon escaping from the lunar soil to better understand what governs the concentration of this noble gas which contributes to the endogenous origin of the lunar exosphere.

4. Is there a carbon emission-return relation? Exploring the existence of a carbon emission return relation in the Swedish stock market
C-uppsats, Handelshögskolan i Stockholm/Institutionen för finansiell ekonomiSammanfattning : We use portfolio sorting and Fama-Macbeth regressions to investigate the potential relation between carbon emissions and stock returns in the Swedish stock market, a country with stringent carbon regulations and taxes. We research the Swedish stock market between 2010-2019 and do not find evidence of such a relationship. LÄS MER
5. Development of methods for detection of radioactive aerosols of special importance for the ESS facility
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : With the construction of the European Spallation Source (ESS) steadily approaching the operational phase, an environmental monitoring program will soon be implemented with the purpose of monitoring emissions. With regard to radiation safety, it is highly important to monitor alpha emitting radionuclides in aerosol form. LÄS MER
