2. 1. Building renovation processes towards low greenhouse gas emissions and energy use

   Author : Stefan Olsson; Tove Malmqvist; Göran Finnveden; Dennis Johansson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Renovation processes; buildings; energy efficiency; greenhouse gas emissions; target levels;

   Abstract : Buildings from the record year era are now 40 – 55 years old and in many cases in need of extensive renovation measures. This need for renovation could be seen as an opportunity to achieve overarching sustainability target levels and to perform renovation with a holistic approach. READ MORE

5. 3. Phase Transitions and Phase Formation of Hydrogen in Quasi-2D Lattices

   Author : Stefan Olsson; Björgvin Hjörvarsson; Yuh Fukai; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; hydrogen; finite-size effects; long-ranged interactions; superlattices; phase transitions; elastic interaction; Fysik; Physics; Fysik;

   Abstract : The role of the dimensionality and strain state of metallic lattices on the phase behavior of dissolved hydrogen was explored. Metallic superlattices with well defined hydrogen absorption potential on the nm scale, were utilized as test systems. READ MORE

6. 4. Assessing Carbon Dioxide Removal methods amid uncertainty : soil carbon sequestration, biochar and harvested wood products as methods for climate change mitigation

   Author : Alexander Olsson; Stefan Grönkvist; Mathias Fridahl; Anders Hansson; Lowe Börjeson; KTH; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon Dioxide Removal CDR ; Negative Emissions Technologies NETs ; Soil Organic Carbon; Biochar; Harvested Wood Products HWP ; Socio-technical systems; Strategic Niche Management SNM ; Chemical Engineering; Kemiteknik;

   Abstract : Measures to sequester carbon dioxide (CO2) away from the atmosphere have become increasingly important in the discussion of which methods humans can employ to limit global warming. These measures, which are broad and varied, fall under the umbrella of Carbon Dioxide Removal (CDR) methods. READ MORE

7. 5. Information and financial markets

   Author : Stefan Anchev; Jörgen Hellström; Rickard Olsson; Juha-Pekka Kallunki; Umeå universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Information; dissemination of information; production of private information; information disadvantage; investor base; stock return anomalies; stock price informativeness; quantity of firm disclosure; less sophisticated individual investors;

   Abstract : The results in this thesis are consistent with the hypotheses that: 1) the incomplete dissemination of information across investors helps in explaining the occurrence and the persistence of cross-sectional stock return anomalies, 2) the properties of the investor base of a stock have implications for the informativeness of the stock's price and 3) a greater quantity of firm disclosure places less sophisticated investors at an information disadvantage. Overall, the thesis provides new empirical evidence about the role of information in financial markets. READ MORE
