1. 16. Market Liquidity and Block Holdings - Empirical evidence from the Swedish market

   Magister-uppsats, Lunds universitet/Företagsekonomiska institutionen

   Författare :Mattias Janfjord; Max Lundblom; [2020]
   Nyckelord :Liquidity; trading activity; ownership structure; blockholders; friction; Business and Economics;

   Sammanfattning : Purpose: Investigate the relation between block ownership and stock liquidity. Methodology: The empirical methods used in this project are of quantitative nature. We use a set of dependent variables representing liquidity measures in order to test how our main explanatory variable, sum of block holdings, affect this. LÄS MER

3. 17. Development of a Water Activity Control and Reaction Monitoring System for Acidolysis and Transesterification Reactions using Immobilized Lipases in a Rotating Bed Reactor

   Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

   Författare :Eimantas Gladkauskas; [2019]
   Nyckelord :Enzyme; Enzymes; Immobilized enzyme; bioreactor; rotating bed reactor; acidolysis; transesterification; arduino; water activity; thermodynamic water activity; Enzyme activity; automatic reaction tracking; reaction tracking; biotechnology; electrical engineering; relative humidity; spinchem; enzymatic synthesis; water activity control; process automation; lipases; lipase; bioteknik; Technology and Engineering;

   Sammanfattning : Controlled water activity in an enzymatic reaction can influence enzyme activity and productivity. A small layer of water around an enzyme gives it a required flexibility to catalyze reactions at a higher rate in contrast with the one that is dry (Adlercreutz, Dicko, Larsson, & Månsson, 2017).

4. 18. Preliminary Lander CubeSat Design for Small Asteroid Detumbling Mission

   Master-uppsats, KTH/Rymdteknik

   Författare :Agne Paskeviciute; [2019]
   Nyckelord :;

   Sammanfattning : Asteroid mining is expected to become reality in the near future. The first step is to redirect an asteroid to a stable Earth orbit so that mining technologies can be demonstrated. Detumbling of the asteroid is one of the important steps in asteroid redirection missions. LÄS MER

5. 19. Nutidsbeskrivning av PFAS i dagvatten för området Frösö Park : Med fokus mot reningsmetoder och hur PFAS-situationen ser ut för framtiden

   Master-uppsats, Karlstads universitet

   Författare :Tore Johansson; [2019]
   Nyckelord :Urban runoff; PFOA; PFOS; Purification methods;

   Sammanfattning : PFAS is a relatively new group of contaminants with unique characteristics, which in the early 21st century was understood being dangerous for both humans and the environment. In 2008, EFSA published a report on guidelines for human intake of PFAS. LÄS MER

7. 20. Evaluation of a digitial displacement pump in a load haul dump application

   Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

   Författare :Jayasurya Madhusudanan; [2019]
   Nyckelord :Digital displacement pump; mine loader; energy efficiency; backward simulation; forward simulation; pump losses;

   Sammanfattning : Hydraulics has always been the first choice of actuation in off-road, construction and mining vehicles due to its power density, low cost, built in cooling and lubrication. However, the current state of our environment along with stricter regulations has brought light to newer technologies within hydraulics to improve the existing system. LÄS MER
