1. 1. Surface and Subsurface Flow Connection and Dominating Runoff Mechanism in Hillslope of Tarfala, Northern Sweden.

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Namika Maharjan; [2023]
   Keywords : Advanced Terrestrial Simulator ATS ; hillslope connectivity; tracer test; hydrological modeling; parameter analysis; sub artic regions; hillslope hydrology;

   Abstract : The Sub artic regions are becoming increasingly important due to the effects of climate change. In northern Sweden, thawing of permafrost has led to significant increases in annual minimum flows in several catchments. READ MORE

3. 2. Potassium in the Galactic Bulge - as traced by microlensed dwarf & sub-giant stars

   University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

   Author : Lukas Jönsson; [2023]
   Keywords : Nucleosynthesis; Galactic Bulge; Potassium; Non-Local-Thermal-Equilibrium; Physics and Astronomy;

   Abstract : During this report the potassium (K) trend in the Galactic Bulge, with respect to metallicity and various α-elements, has been computed and evaluated by a method of line synthesis on the 7698.96 ̊A KI line (7699 KI), where Non-Local-Thermal-Equilibrium (NLTE) effects have been considered.

4. 3. Total body perfusion imaging with 15O-water PET

   University essay from Umeå universitet/Institutionen för fysik

   Author : Anna Åhlström; [2023]
   Keywords : ;

   Abstract : Background Positron emission tomography scanners can be used together with the PET tracer 15O-water to image perfusion in the body. It has mainly been used to image perfusion in the brain and heart. The new total-body PET scanners have a larger axial field-of-view, making imaging of the whole body possible without moving the patient. READ MORE

5. 4. Visualizing osteonecrosis of jaws through neutrophil elastase : [11C]NES novel PET tracer

   University essay from Uppsala universitet/Institutionen för läkemedelskemi

   Author : Amanda Dannberg; Theodora Martinez; [2023]
   Keywords : [11C]NES; HNC; MRONJ; neutrophil granulocytes; ORN; osteonecrosis; PET CT; radiation therapy; [11C]NES; huvud- och halscancer; MRONJ; neutrofila granulocyter; ORN; osteonekros; PET CT; strålbehandling;

   Abstract : Radiation and medical drugs are used to fight head and neck cancer, but unfortunately in some cases these treatments cause development of other diseases and injuries. Osteoradionecrosis (ORN) and medical-related osteonecrosis of the jaw (MRONJ) are dreaded late complications in jaws from radiation therapy and medical drugs and cause great suffering to those affected.

6. 5. Evaluation of whole-body bone scans performed using a gamma camera with Cadmium Zinc Telluride detector

   University essay from

   Author : Victor Asp; [2022-01-13]
   Keywords : Medical physics; whole-body bone scans; gamma camera; Cadmium Zinc Telluride detector;

   Abstract : The bone scan is a common nuclear medicine imaging procedure that is mainly used for evaluating several oncological patient groups. A radioactive tracer, 99mTc -labelled diphosphonate, is injected intravenously and accumulates in the skeleton. The distribution of the tracer in the body is measured with a gamma camera 3 hours post-injection. READ MORE
