3. 7. Investigation of Ilmenite from Oxygen Carrier Aided Combustion: Sulfur Interactions and Recovery of Elements

   Författare :Mariane Vigoureux; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Recycling; Oxygen Carrier Aided Combustion; Circulating-Fluidized Bed; Ash; Sulfate process; Sulfur; Biomass; Ilmenite; Leaching;

   Sammanfattning : Oxygen- Carrier- Aided Combustion (OCAC) is a promising technology for the combustion of solid heterogeneous fuels such as biomass and waste in fluidized-bed (FB) units. In OCAC the conventional bed material silica sand is replaced by an oxygen carrier (OC). Replacing the bed material with an OC has many advantages. LÄS MER

4. 8. Haptic and visual simulation of material cutting process : a study focused on bone surgery and the use of simulators for education and training

   Författare :Magnus G. Eriksson; Jan Wikander; Ingela Nyström; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; surgical simulation; virtual reality; haptic feedback; surgical training; medical simulators; metrics; 3D visualization; Medical technology; Medicinsk teknik;

   Sammanfattning : A prototype of a haptic and virtual reality simulator has been developed for simulation of the bone milling and material removal process occurring in several operations, e.g. temporal bone surgery or dental milling. The milling phase of an operation is difficult, safety critical and very time consuming. LÄS MER

5. 9. The EEG of the Neonatal Brain – Classification of Background Activity

   Författare :Johan Löfhede; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hypoxia; newborn; segmentation; asphyxia; cerebral; classification; neonatal; EEG;

   Sammanfattning : The brain requires a continuous supply of oxygen and nutrients, and even a short period of reduced oxygen supply can cause severe and lifelong consequences for the affected individual. The unborn baby is fairly robust, but there are of course limits also for these individuals. The most sensitive and most important organ is the brain. LÄS MER

7. 10. Expanding the versatility and functionality of iontronic devices

   Författare :Dennis Cherian; Magnus Berggren; Daniel T Simon; Klas Tybrandt; Alon Gorodetsky; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Biological systems rarely use electrons as signal regulators, most of the transport and communication in these system utilize ions. The discovery of conjugated polymers and polyelectrolytes and their unique properties of mixed ionic electronic properties opened the possibility of using these in the domain of bioelectronics, which paved the way for the field of organic bioelectronics.
