2. 11. Design and characterization of direct electron transfer based biofuel cells including tests in cell cultures

   Author : Peter Lamberg; Malmö högskola; []
   Keywords : biofuel cell; enzymatic fuel cell; direct electron transfer; cellobiose dehydrogenase; biocompatibility; enzyme kinetics; cell culture;

   Abstract : Enzymatic fuel cells (EFCs) are bioelectronic devices based on redox enzymes, which convert chemical energy into electrical energy via biochemical reactions. A major difficulty to overcome is to successfully connect (using e.g., immobilization) the enzymes to the electrode surface. READ MORE

4. 12. Sex and stress steroid modulation of GABA mediated chloride ion flux in rat CNS

   Author : Jessica Strömberg; Per Lundgren; Torbjörn Bäckström; David Haage; Esa Korpi; Umeå universitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; allopregnanolone; chloride ion uptake; patch-clamp; 3beta-steroids; kinetic parameters; rat brain; Obstetrics and gynaecology; Obstetrik och gynekologi;

   Abstract : Background: Sex and stress steroids are metabolized to 3a-hydroxy-pregnane-steroid metabolites such as allopregnanolone (Allo) and tetrahydrodeoxycorticosterone (THDOC). Allo and THDOC are neuroactive steroids that are metabolized in the brain and act in brain as potent positive GABAA receptor function modulators. READ MORE

   Abstract : Schizophrenia is a severe psychiatric disorder affecting approximately 20 million people worldwide. The disease consists of positive symptoms e.g. hallucinations, negative symptoms such as anhedonia, and cognitive deficits, e. READ MORE

6. 14. Electrical Charges on Polymeric Insulator Surfaces and their Impact on Flashover Performance

   Author : Sarath Kumara; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; streamer criterion; polymeric insulation; flashover voltage; surface potential; bulk conductivity; surface conduction; humidity; bulk neutralization; charge decay; Surface charge; silicone rubber; corona charging; gas neutralization;

   Abstract : Utilization of remotely located sustainable energy resources such as solar, wind and hydro calls for further developments of long-distance electric power transmissions operating at ultra-high voltage (UHV) levels which may exceed 1000 kV ac and 800 kV dc utilized today. It is foreseen that insulation of such transmission systems is to be based on polymeric materials that can provide a number of technical benefits over traditionally used glass and porcelain based insulation.

7. 15. Characteristics of streamer discharges in air and along insulating surfaces

   Author : Lan Gao; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; Electricity; Esp The Study Of Transients and Discharges; elektricitetslära; ssk studiet av transienter och urladdning;

   Abstract : Power quality is dependent on the dielectric properties of the insulators used throughout the power generation and power transmission utilities. Knowledge of the pre-discharge stage associated with the electrical breakdown across outdoor insulators is essential if one is to improve the performance of these insulators under various electrical and environmentalconditions.
