   Abstract : Catalytic systems are one of the most effective technologies of modern chemical processes. The system uses a molecule called ‘catalyst’ that is capable of catalyzing a reaction without being produced or consumed during the process. READ MORE

4. 2. MRI with MR Angiography in Endovascular Repair of Abdominal Aortic Aneurysms

   Author : Lena Engellau; Malmö Diagnostisk radiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering; tomography; radiology; Clinical physics; Contrast media complications; Cost analysis; MR velocity mapping; Artefacts; MR imaging safety; MR angiography; MR imaging; Endovascular repair; Stent-graft; aortic; Aneurysm;

   Abstract : The aim of this study was to evaluate MRI with contrast enhanced MR angiography (MRI/CE MRA) as imaging method before and after endovascular repair of abdominal aortic aneurysms (AAA). A 1.5 T scanner was used for all examinations. In this prospective study 26 consecutive patients were included. READ MORE

5. 3. Geometric distortions in MRI based radiotherapy and PET/MRI

   Author : Josef Lundman; Tufve Nyholm; Anne Larsson; Jörgen Olofsson; Marco Riboldi; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic resonance imaging; MRI; PET MR; PET MRI; medical imaging; radiotherapy; geometrical distortions; MR-only; MRI-only; radiofysik; radiation physics;

   Abstract : Magnetic resonance imaging (MRI) offers high soft-tissue contrast compared to computed tomography (CT). This contrast is helpful in many cases, not least for delineating tumours for radiotherapy treatment, and has led to increasing use in radiotherapy treatment planning (RTP). READ MORE

   Abstract : The management of rectal cancer has changed in many countries over the last two decades and resulted in improved survival for the majority of rectal cancer patients. In this thesis some surgical strategies and histopathological aspects to improve and clarify the management of rectal cancer patients are investigated. READ MORE

7. 5. Bonded Particle Model for Jointed Rock Mass

   Author : Diego Mas Ivars; Joanne MR Fernlund; John Harrison; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bonded particle model; Smooth-joint contact model; Discrete fracture network; Synthetic rock mass; Jointed rock mass; Geoengineering; Geoteknik;

   Abstract : Jointed rock masses are formed of intact rock and joints. There-fore, proper characterization of rock mass behavior has to consid-er the combined behavior of the intact rock blocks and that of the joints. This thesis presents the theoretical background of the Synthetic Rock Mass (SRM) modeling technique along with example applica-tions. READ MORE
