1. 11. Cancer in organ transplant recipients

   Författare :Caroline Stenman; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancer; organ transplantation; skin cancer; heart transplantation; lung transplantation;

   Sammanfattning : Tens of thousands of transplantations are performed around the world each year. Organ transplant recipients (OTR) are obliged to receive life-long medical treatment with immunosuppressive drugs to ensure graft function. However, such medications entail an increased risk of developing a broad spectrum of malignancies, especially skin cancer. LÄS MER

3. 12. Verification of Dose Calculation Algorithms in Treatment Planning Systems for External Radiation Therapy: A Monte Carlo Approach

   Författare :Elinore Wieslander; Lund Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiologi; tomografi; medicinsk instrumentering; radiotherapy; dose calculation algorithm; verification; Monte Carlo calculation; electron beam; photon beam; Clinical physics; radiology; tomography; medical instrumentation; Klinisk fysiologi; treatment planning system;

   Sammanfattning : This thesis presents a new verification concept, the virtual accelerator, for dose calculation algorithms used in treatment planning systems (TPSs) for external beam radiotherapy. The algorithm input data required to implement a treatment unit in the TPS are generated by Monte Carlo simulations as are the beam reference data needed for the subsequent evaluation of the dose calculation algorithm.

4. 13. On Reduction of Production Disturbances in Manufacturing Systems Based on Discrete-Event Simulation

   Författare :Arne Ingemansson; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatiska system; robotteknik; reglerteknik; Production technology; Produktionsteknik; control engineering; robotics; Automation; manufacturing system; Discrete-event simulation DES ; production disturbance reduction;

   Sammanfattning : Improved efficiency in manufacturing systems to achieve increased output and thus reduced production disturbances is a vital area. DES (Discrete-Event Simulation) can visualize and study the dynamic issues related to total efficiency in manufacturing systems. A methodology for production disturbance reduction is presented.

5. 14. Dual targeting of proteins to mitochondria and chloroplasts : Characterization of dual targeting peptides and their interaction with organellar receptors

   Författare :Erika Spånning; Elzbieta Glaser; Anthony Moore; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; biokemi;

   Sammanfattning : Most mitochondrial and chloroplastic proteins are synthesized in the cytosol as precursor proteins with an N-terminal targeting peptide (TP), which directs them to the correct organelle. There is also a group of proteins that are dual targeted to mitochondria and chloroplasts using an ambiguous N-terminal dual targeting peptide (dTP). LÄS MER

7. 15. Organizational Innovations: A conceptualization of how they are created, diffused and sustained

   Författare :Annika Steiber; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sustaining innovation; innovation; Lean; diffusion of innovation; organizational innovation; TQM; Toyota Production System; innovation management; creation of innovation; Google;

   Sammanfattning : Organizational innovations are essential for firms’ long-term competitiveness. In spite of this, there is less research on organizational innovations than on technical innovations. The purpose of this thesis is to contribute to our understanding of how organizational innovations are created, diffused, and sustained. LÄS MER
