1. Constructing a Social Profitability Index: Socially Responsible Investing in Electric Utilities
University essay from Handelshögskolan i Stockholm/Institutionen för finansiell ekonomiAbstract : Building on a theory about the Social Profitability Index (SPI), this paper is the first to construct an SPI in practice ranking investment opportunities based on social and financial returns within the electric utility industry. The social return is the investor-preference weighted social gain from avoiding carbon emissions by changing to renewable production technology in a firm. READ MORE

2. Solving the BECCS Puzzle - The Role of Knowledge Brokers in the Science-Policy Interface around BECCS in Sweden
University essay from Lunds universitet/LUCSUSAbstract : Negative emissions and bioenergy with carbon capture and storage (BECCS) are seen as important strategies in order to reach climate neutrality by 2045 in Sweden. However, it remains largely unclear to what extent scientific knowledge has contributed to the formulation of the climate neutrality policies. READ MORE

3. The effect of water on the orientation of a protein in an electric field
University essay from Uppsala universitet/Institutionen för fysik och astronomiAbstract : Structure determination of proteins is vital for the understanding of their function. It often relies on techniques that use intense X-ray pulses to create diffraction patterns of protein crystals, which then contain information on the three-dimensional structure of the crystallised protein.

4. On-chip Instrument Access Through System Hierarchy
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : There are many advantages with the development towards Integrated Circuits (ICs) with smaller, faster, and more transistors. However, tighter margins lead to a need of on-chip instruments to test, tune, and configure. These on-chip instruments, which can be in the range of thousands per IC, must be accessed through the life-time. READ MORE

5. Sustaining Orientation of Ubiquitin for Single Particle Imaging Using Electric Fields
University essay from Uppsala universitet/Kemisk och biomolekylär fysik; Uppsala universitet/Energimaterialens fysikAbstract : Single-particle imaging, or SPI, is a method used to obtain the three-dimensional structure of particles. Repeatedly aiming X-rays at samples of a particle produces diffraction patterns, which are combined to a best-fit three-dimensional model of the particle. SPI of proteins can be improved by orienting the protein before imaging. READ MORE
