2. 16. Transient Spray Mode Fuel Injection

   Author : Lokesh Mopuri; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; clogged nozzle; non-evaporative and reactive spray; thimble structure; Spray characteristics;

   Abstract : This research examines the pivotal role of transient fuel spray in internal combustion engines, primarily focusing on their influence on dual-fuel (DF) engines. In the case of dual-fuel (DF) engines functioning in a gas mode, the controlling of the primary fuel’s ignition is usually managed through the direct injection of liquid pilot fuel. READ MORE

4. 17. Lateral epicondylitis : intramuscular blood flow, pressure and metabolism in the ECRB muscle

   Author : Eva Oskarsson; Karin Piehl Aulin; Eva Nylander; Örebro universitet; []
   Keywords : Lateral epicondylitis; ECRB; intramuscular microcirculation; intramuscular pressure; botulinum toxin; muscle metabolism; pain; MEDICINE; MEDICIN; Idrottsvetenskap; Sports Science;

   Abstract : Lateral epicondylitis is classified as an overuse injury and the main symptom is pain from the lateral side of the elbow. There is general agreement that the extensor carpi radialis brevis (ECRB) muscle and its proximal tendon play a central role in the development of lateral epicondylitis. However, the pathophysiology is to a large extent unclear. READ MORE

5. 18. System Simulation of Partially Premixed Combustion in Heavy-Duty Engines : Gas Exchange, Fuels and In-cylinder Analysis

   Author : Erik Svensson; Förbränningsmotorer; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Partially Premixed Combustion PPC ; Compression ignition; Direct injection; Methanol; Engine optimization; Stochastic reactor model; T-phi diagrams; Partially premixed combustion; Compression Ignition; Direct Injection; Methanol; Engine Optimization; Stochastic reactor model; Gas exchange; T-phi diagrams;

   Abstract : The concept of partially premixed combustion (PPC), applied to conventional diesel engines, has shown to yield high gross efficiencies and low emissions of oxides of nitrogen and soot. PPC emerged from the knowledge gained from homogeneous charge compression ignition (HCCI) research. READ MORE

6. 19. Characterization of injection molded polymers – from conventional to wood-based thermoplastics

   Author : Linnea Björn; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAXS; WAXS; melt processing; injection molding; Hierarchical Materials; Polyethylene; Dialcohol cellulose;

   Abstract : The success of polymers products is associated with the melt processability, which allows to create products with complex shapes at a low cost. One of the most widely used processing techniques utilizing melt processability is injection molding, where a polymer is heated until it flows into a mold under pressure. READ MORE

7. 20. Glutamate Turnover and Energy Metabolism in Brain Injury : Clinical and Experimental Studies

   Author : Carolina Samuelsson; Elisabeth Ronne-Engström; Lars Hillered; Eva Kumlien; Carl-Henrik Nordström; Uppsala universitet; []
   Keywords : Neurosciences; glutamate; glutamine; lactate; pyruvate; microdialysis; GLT-1; energy metabolism; intracranial pressure; cerebral perfusion pressure; subarachnoid hemorrhage; ischemia; epilepsy; Neurovetenskap;

   Abstract : During brain activity neurons release the major excitatory transmitter glutamate, which is taken up by astrocytes and converted to glutamine. Glutamine returns to neurons for re-conversion to glutamate. This glutamate-glutamine cycle is energy demanding. READ MORE
