1. 1. Sputter Deposition, Mechanical Properties, and Thermal Stability of Nitride Based Superlattices

   Författare :Carolina Engström; Helmut Holleck; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Investigations concerning deposition, mechanical properties and thermal stability of nitride-based superlattice films have been performed. X-ray diffraction and transmission electron microscopy techniques were adopted for microstructural characterization, while nanoindentation hardness and abrasive wear resistance measurements were utilized for evaluation of mechanical properties.

3. 2. Glutamate Turnover and Energy Metabolism in Brain Injury : Clinical and Experimental Studies

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

   Sammanfattning : 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. LÄS MER
