1. 16. Planned Change and Inertia : Integrating Technology, Organization and Human Aspects

   Författare :Eva Lovén; Horst Hart; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : New work organization and new computer-based tools can save costs and improve quality. A fact that often is not acknowledged is that new work organization and new computer-based tools take resources from the organization.Three empirical studies were performed in production, concerning changed work organization and managerial innovation.

3. 17. Synthesis and Characterization of ZnO/Graphene Nanostructures for Electronics and Photocatalysis

   Författare :Seyed Ebrahim Chalangar; Håkan Pettersson; Magnus Willander; Omer Nur; Christian Falconi; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; zinc oxide; graphene; nanostructure; nanocomposite; conjugated electronics; photocatalysis; nanofabrication; colloidal lithography; chemical bath deposition; sol-gel;

   Sammanfattning : Recent rapid development of electronics and electro-optical devices demands affordable and reliable materials with enhanced performance. Forming nanocomposites of already well-known materials is one possible route towards novel functional materials with desirable synergistic enhanced properties. LÄS MER

4. 18. Cellulose–Assisted Dispersion of Carbon Nanotubes : From Colloids to Composites

   Författare :Alireza Hajian; Lars Berglund; Milo Shaffer; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanocelluloses; Carbon nanotubes; Composites; Colloids; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Sammanfattning : It is a challenge to disperse nanoparticles to obtain a nanostructured composite. This thesis aims at providing a new route to fabricate carbon nanotube (CNT) composites and suggests mechanisms for nanocellulose–CNT interactions. This route is based on unmodified CNT dispersed in water with the help of nanocellulose. LÄS MER

5. 19. On optical methods for intracerebral measurements during stereotactic and functional neurosurgery : Experimental studies

   Författare :Johan Antonsson; Karin Wårdell; Lars-Erik Augustinsson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser Doppler perfusion monitoring; Diffuse reflectance spectroscopy; Functional and stereotactic neurosurgery; Medical engineering; Medicinsk teknik;

   Sammanfattning : Radio frequency (RF) lesioning and deep brain stimulation (DBS) are the two prevailing surgical treatments for movement disorders within the field of stereotactic and functional neurosurgery. For RF-lesioning, a small volume of brain tissue is coagulated and knowledge of the lesion size and growth is of great importance for the safety and outcome of the procedure. LÄS MER

7. 20. Space and Time Configurations in Telemedicine

   Författare :Jesper Petersson; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Telemedicine; ICT; Time; Space; Science Technology Studies; Technofeminism; Actor-Network Theory;

   Sammanfattning : Sammanfattning: Denna licentiatavhandling är en socioteknisk och spatiotemporal studie av praktiserande av hälso‐ och sjukvård med hjälp av informations‐ och kommunikationsteknik (IKT), eller s k telemedicin. IKT förknippas ofta med möjligheten att överkomma tid och rum och tillåta åtkomst av sådant som finns någon annanstans. LÄS MER
