1. 21. Electrochemical Reactions of Quinones at Conducting Polymer Electrodes

   Författare :Canyan Che; Xavier Crispin; Mikhail Vagin; Magnus Jonsson; Viktor Gueskine; Mieczyslaw Lapkowski; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Proton-coupled multielectron transfer reactions are of great abundance in Nature. In particular, two-proton-two-electron transfers in quinone/hydroquinone redox couples are behind oxidative phosphorylation (ADP-to-ATP) and photosystem II. LÄS MER

3. 22. Development of Second and Third Generation Bioelectronics

   Författare :Federico Tasca; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; flow injection analysis; amperometric biosensor; mediated electron transfer; direct electron transfer; tryptophan repressor-binding protein; diaphorase; pyranose oxidase; cellobiose dehydrogenase; pyranose dehydrogenase; biofuel cell; spectroelectrochemistry; single wall carbon nanotubes; bioelectronics.;

   Sammanfattning : The field of research dealing with the integration of biomolecules with electronic elements to form functional devices is called ‘‘bioelectronics’’. Bioelectronics based on mediated electron transfer (MET) between the biological element and the electrodes are designated as “second generation” while the one based on direct electron transfer (DET) is specified as “third generation”.

4. 23. Development and Implementation of Cardiac Event Detectors in Digital CMOS

   Författare :Joachim Rodrigues; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Elektronik och elektroteknik; Electronics and Electrical technology; event detection; cardiac pacemaker; sleep- transistors; low-power; ASIC; Neural Networks; Electrogram; Signalbehandling; Wavelets;

   Sammanfattning : This doctoral dissertation presents the development and digital hardware realization of cardiac event detectors. Implantable medical appliances, as the cardiac pacemaker, have progressed from a life sustaining device to a device that considerably improves life quality for all ages. LÄS MER

5. 24. Intraperitoneal Chemotherapy of Ovarian Cancer

   Författare :Henric Malmström; Kamma Berthelsen; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Ovarian cancer is still the most common cause of death among gynecologic malignancies in spite of the fact that newer and more effective drugs and/or administration techniques have been developed in the last decade. However, substantial improvements in response rate andprogression-free survival have been reported in many studies. LÄS MER

7. 25. Detection and Classification in Electrocardiac Signals

   Författare :Magnus Åström; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal processing; morphology classification; QRS detection; ischemia; body position changes; electrogram; ECG; electrocardiogram; clustering; classification; Detection; sensing;

   Sammanfattning : Signal processing can be used to condition medical signals to facilitate their interpretation, and to extract clinically important information. The purpose of the present doctoral thesis is to put forward solutions to certain problems encountered in the processing of electrocardiac signals. LÄS MER
