1. 6. CT Urography : Efforts to Reduce the Radiation Dose

   Författare :Pär Dahlman; Anders Magnusson; Anders Sundin; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Urinary tract malignancy; renal cell carcinoma; urography; x-ray computed tomography; radiation dosage; dose escalation; hematuria diagnosis; Diagnostic radiology; Diagnostisk radiologi; Radiologi; Radiology;

   Sammanfattning : Computed tomography urography (CTU) is today the imaging method used to investigate patients with suspected urinary tract malignancy, replacing the old imaging method intravenous pyelography (IVP) about a decade ago. The downside of this shift was that the effective radiation dose to the examined patient was eight times higher for CTU compared to IVP. LÄS MER

3. 7. Analysis of High-Frequency Electrical Transients in Offshore Wind Parks

   Författare :Tarik Abdulahovic; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; very fast transient; surge protection; surge; transient overvoltage; restrikes; prestrikes; breaker; voltage escalation;

   Sammanfattning : In this thesis, a study of high frequency electromagnetic transient phenomena is performed. Models of various components needed for simulations of high frequency transients, such as for transformers, cables and breakers are developed. LÄS MER

5. 9. Passing the open windows : A quantitative and qualitative approach to immediate military balance and escalation of protracted conflicts

   Författare :Björn Holmberg; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Peace and conflict research; Window of opportunity; realism; balance of power; rational choice; organizationtheory; learning; Freds- och konfliktforskning; Peace and conflict research; Freds- och konfliktforskning; Peace and Conflict Research; freds- och konfliktforskning;

   Sammanfattning : This dissertation has a dual point of departure: first, the widely known concept of window of opportunity and its application in the study of international relations (IR) and, second, the notion among modern classical realists that states maximize their power and, hence, that windows of opportunity should increase the probability of escalation to war or escalation of a war.The focus is primarily on the effects of rapid power shifts in dyads of non-great powers experiencing protracted conflict.

7. 10. Model-Based Optimization of Clinical Trial Designs

   Författare :Camille Vong; Mats O. Karlsson; Andrew C. Hooker; Lena E. Friberg; Marylore Chenel; Oliver Sander; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nonlinear mixed-effects models; pharmacometrics; likelihood ratio test; NONMEM; power; sample size; study design; proof-of-concept; dose-finding; population optimal design; LOQ; BQL data; neutropenia; docetaxel; myelosuppression; thrombocytopenia; MTD; Bayesian methods; 3 3 algorithm; dose escalation study; Pharmaceutical Science; Farmaceutisk vetenskap;

   Sammanfattning : General attrition rates in drug development pipeline have been recognized as a necessity to shift gears towards new methodologies that allow earlier and correct decisions, and the optimal use of all information accrued throughout the process. The quantitative science of pharmacometrics using pharmacokinetic-pharmacodynamic models was identified as one of the strategies core to this renaissance. LÄS MER
