1. 21. The Influence of Xylan on Precipitation and Filtration Properties of Lignin : A Study in the Context of the LignoBoost Process

   University essay from KTH/Skolan för kemivetenskap (CHE)

   Author : Helen Schneider; Lynn Schneider; [2016]
   Keywords : Xylan; Lignin; Precipitation; FBRM; LignoBoost process;

   Abstract : The LignoBoost process is a valuable supplement to the Kraft process. It can increase the pulp production rate of a Kraft mill and it enables lignin separation from black liquor with a high degree of purity. However, residual xylan in black liquor has been observed to increase filtration resistance of lignin during the LignoBoost process. READ MORE

3. 22. Investigation of the frost resistance in bacteria treated self-healing concrete

   University essay from Lunds universitet/Avdelningen för Byggnadsmaterial

   Author : Karin Persson; [2016]
   Keywords : Concrete; Hydraulic Structures; Hydro Power; Frost Resistance; Self- healing; Bacteria; Precipitation; Calcium Carbonate Betong; Vattenbyggnader; Vattenkraft; Frostbeständighet; Självläkn- ing; Bakterier; Utfällning; Kalciumkarbonat; Technology and Engineering;

   Abstract : Vattenkraften står för hälften av vårt elbehov i Sverige idag. Merparten av vattenkraftverken är gjutna i betong och som många andra betongkonstruktioner så drabbas betongen av sprickbildning av olika orsaker. För vattenkraften är genomgående sprickor ett problem då dessa skapar läckage. READ MORE

   Abstract : Målet med detta projekt var att studera två sorters bakterier, Actinobacillus succinogenes och Basfia succiniciproducens, och deras produktion av bärnstenssyra. Bärnstenssyra är en dikarboxylsyra som även är en metabolit i citronsyracykeln. READ MORE

6. 25. Design and Construction of a Self-Deployable Structure for the Moon House Project

   University essay from KTH/Lättkonstruktioner

   Author : Marcus Dahl; [2015]
   Keywords : ;

   Abstract : This master thesis describes the design and construction of a prototype for the Moon House project. The goal was to develop a structural concept which ultimately will allow a 2 × 2.5 × 3 m3 house to be deployed on the surface of the Moon as an art installation. A 1 to 5 scale model was built and tested. READ MORE
