1. 1. Specific Precipitation of Biomolecules Using Synthetic Polymers

   Författare :Per-Olof Wahlund; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Polymerteknik; RNA; plasmid DNA; DNA; polyelectrolyte complexes; synthetic polymers; precipitation; affinity precipotation; Bioteknik; Polymer technology; biopolymers;

   Sammanfattning : Purification is a very important stage in biotechnological processes. The traditionally used precipitation techniques are generally nonspecific and thus one or more chromatographic steps are normally required. There is thus a need for new approaches to improve existing techniques. LÄS MER

   Författare :Alexandra Dimitrijevic Carlsson; Per Alstergren; Kerstin Wahlund; Carin Starkhammar Johansson; Martina. Frodlund; Bijar Ghafouri; Robin Kahn; Malmö universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomarkers; Juvenile Idiopathic Arthritis; Magnetic resonance imaging; Orofacial pain; Parotid gland; Plasma; Psychological distress; Psychosocial; Saliva; Stress; Temporomandibular joint; Biomarkörer; Juvenil idiopatisk artrit; Käkled; Magnetisk resonanstomografi; Orofacial smärta; Saliv; Spottkörtel; Stress;

   Sammanfattning : Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in children. The disease can affect the temporomandibular joint (TMJ) and cause orofacial growth disturbances, pain, and jaw dysfunction. TMJ arthritis is often asymptomatic and therefore a challenging joint to diagnose. LÄS MER

4. 3. Acceleration of Compressible Flow Simulations with Edge using Implicit Time Stepping

   Författare :Evelyn Otero; Arthur Rizzi; Jesper Oppelstrup; Per Wahlund; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; compressible CFD; convergence acceleration; implicit time-stepping; matrix dissipation; line-implicit; performance optimization;

   Sammanfattning : Computational fluid dynamics (CFD) has become a significant tool routinely used in design and optimization in aerospace industry. Typical flows may be characterized by high-speed and compressible flow features and, in many cases, by massive flow separation and unsteadiness. LÄS MER

5. 4. Rational bioenergy utilisation in energy systems and impacts on CO2emissions

   Författare :Bertil Wahlund; KTH; []
   Nyckelord :CO2 reduction; energy system; biofuel; CHP; refining; fuel pellets; ethanol; methanol; DME; fuel substitution; sewage water; nitrification;

   Sammanfattning : The increased concentration of greenhouse gases in theatmosphere, in particular CO2, is changing the Earth’s climate. Accordingto the Kyoto protocol, where the international community agreedon binding emission targets, developed countries are committedto reduce their greenhouse gas emissions. LÄS MER
