2. 11. The regulation of factor Va activity by activated protein C -Importance of the individual activated protein C cleavage sites in factor Va

   Author : Eva Norström; Malmö Klinisk kemi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellulära vätskor; Hematologi; extracellular fluids; Haematology; activated protein C resistance; activated protein C; Blood coagulation; Factor V;

   Abstract : The subject of this thesis is the activated protein C (APC)-mediated inactivation of factor Va. The activated form of factor V (FVa) is a procoagulant cofactor for Factor Xa (FXa) in the conversion of prothrombin to thrombin. READ MORE

4. 12. Shrinkage and Related Properties of Alkali-Activated Binders Based on High MgO Blast Furnace Slag

   Author : Abeer Humad; Andrzej Cwirzen; John L. Provis; Karin Habermehl-Cwirzen; Andrzej Garbacz; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alkali-activated slag; alkali-activated materials; high-MgO blast furnace slag; shrinkage; creep; carbonation; strength; heat curing; Byggmaterial; Building Materials;

   Abstract : Concrete is the second most used material in the world just after water. A drawback is that it is mostly based on Portland cement, which has an extremely high carbon footprint reaching a staggering 900 kg/tonne. The carbon dioxide emissions related to the production of the Portland cement accounts for nearly 8 % of the global total. READ MORE

5. 13. Properties and applications of materials based on graphite oxide

   Author : Andreas Nordenström; Aleksandr V. Talyzin; Thomas Wågberg; Andrey Turchanin; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Graphene; Graphite Oxide; Graphene Oxide; Swelling; Phase Transition; Intercalation; Activated Graphene; Activated Carbon; Supercapacitors; Neutron Reflectometry;

   Abstract : Graphite oxide (GO) is a hydrophilic, layered material prepared by oxidation of graphite. In the first part of this thesis, we studied materials produced from GO by intercalation and functionalization. The second part of the thesis was focused on supercapacitor applications of high surface area carbons prepared from GO using chemical activation. READ MORE

6. 14. Control of Nitrogen Removal in Activated Sludge Processes

   Author : Pär Samuelsson; Bengt Carlsson; Gustaf Olsson; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; activated sludge process; non-linear control; external carbon addition; multivariable control; cost-efficient operation; feedforward control; simulators; Automatic control; Reglerteknik; Reglerteknik; Automatic Control;

   Abstract : More stringent requirements on nitrogen removal from wastewater are the motivation for this thesis. In order to improve treatment results and enhance cost-efficient operation of wastewater treatment plants, model based control strategies are presented. A Java based simulator for activated sludge processes (JASS) is presented. READ MORE

7. 15. The Optimal trigger speed of vehicle activated signs

   Author : Diala Jomaa; Högskolan Dalarna; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; optimal trigger speed; vehicle activated sign; vehicle mean speed; standard deviation; calibration; Doppler radar; driver behaviour; data analysis; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

   Abstract : The thesis aims to elaborate on the optimum trigger speed for Vehicle Activated Signs (VAS) and to study the effectiveness of VAS trigger speed on drivers’ behaviour. Vehicle activated signs (VAS) are speed warning signs that are activated by individual vehicle when the driver exceeds a speed threshold. READ MORE
