1. 16. Mineral elements in clover- and grass forage in Sweden

   University essay from SLU/Dept. of Animal Nutrition and Management

   Author : Kajsa Lätt; [2019]
   Keywords : soil; maps; forage; macro minerals; micro minerals;

   Abstract : Minerals are essential elements for all living organisms. Plants and animals need minerals to function and maintain a balanced physiological state. Minerals are also important in the ecological cycle. The minerals originate in the soil and makes the foundation of the plants nutritional value for the animals. READ MORE

3. 17. Iodine Quantification Using Dual Energy Computed Tomography and applications in Brain Imaging

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Veronica Fransson; [2019]
   Keywords : Physics and Astronomy;

   Abstract : Purpose/Background Dual Energy Computed Tomography (DECT) have been clinically available for over ten years. Two such systems are currently used at Skane University Hospital (SUS) in Lund. By utilizing materials different attenuating properties at different energies, material decomposition and iodine quantification is possible. READ MORE

4. 18. Manufacturing optimization and film stability analysis of PbS quantum dot solar cells

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Erik Bryngelsson; [2019]
   Keywords : Quantum dots; Solar cells; Photovoltaics; PbS; Optimization;

   Abstract : Semiconductor colloidal quantum dots have an interesting potential to increase solar cell efficiency, with strong absorption in the infrared region and a tunable band gap. In this work an attempt was made to adopt a manufacturing process for PbS quantum dot solar cells, proven successful at Uppsala University. READ MORE

5. 19. Volume calculation of the thyroid gland from SPECT images based on Monte Carlo simulations

   University essay from Umeå universitet/Radiofysik; Umeå universitet/Institutionen för fysik

   Author : Niklas Palmqvist; [2018]
   Keywords : nuclear medicine xeleris thyroid hyperthyroidism thyrotoxicosis monte carlo technetium iodine;

   Abstract : In this study the volume determination which is a part of the doseplanning for patients with thyrotoxicosis was investigated. The aim was to find an accurate method to determine the active volume with single photon emission tomography (SPECT) which in several studies have shown better results than with the currently used method planar scintigraphy (PS).

6. 20. Simulations and Measurements of radiation doses from patients treated with I-131.

   University essay from Umeå universitet/Radiofysik

   Author : Daniel Gälman; [2018]
   Keywords : I-131; Iodine-131; Monte-Carlo Simulations; dose rate measurements; taxi driver; newborn; thyrotoxicosis; restriction times; thyroid cancer;

   Abstract : The aim of this work is to introduce a couple of new exposure scenariosof interest when personnel, family members and general public are externally irradiated from patients treated with Iodine-131. A series of modied ORNL matematical phantoms were used in Monte-Carlo simulations in PENELOPE-2011 to determine dose rates to: a cab driver where thepatient sits in the back seat at opposite side, a newborn child held by an adult patient, a doctor giving treatment to a patient while leaning over the hospital bed and collective effective dose to bus passengers if the patient travels home by bus.
