11. Hydrodynamic modelling of fate and transport of natural organic matter and per- and polyfluoroalkyl substances in Lake Ekoln
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : Societies are facing great challenges with obtaining a good quality and quantity of drinking water in the context of climate change. Increases in natural organic matter (NOM) and per- and polyfluoroalkyl substances (PFAS) have been observed in lakes and drinking water the past years, which is of great concern for water treatment plants in Sweden.

12. Measurement of timescales of cortical neuronal activity in behaving mice
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Electrical activity is omnipresent throughout the brain, and it varies dependant on the brain region. Areal hierarchy has been suggested to be one of the main principles of the organization of the brain, but there is not a lot of evidence available related to the specialization of the brain’s regions in the temporal domain, that is, how the activity evolves over time.

13. Evaluation of internal dosimetry for 225- Ac using one single measurement based on 111-In imaging
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Background and aim: There is a high interest in determining the absorbed dose in tumors and organs for various radiotherapy cancer treatments. Due to limitations in today's methods of determining the patient specific absorbed dose it is usually not proceeded clinically. READ MORE

14. Dark Photon decay generated by muons in the SHiP experiment
University essay from Uppsala universitet/Institutionen för materialvetenskapAbstract : This project has investigated the muon background of the SHiP experiment to determine whether it can boost the experiment sensitivity to visible Dark Photon decay. Using Fermi-Weizsäcker-Williams approximation to muon scattering we found the probability of muons generating massive photons, using Bremsstrahlung and direct lepton pair production as an estimation of the frequency of muon EM-interactions.

15. Attractor Neural Network modelling of the Lifespan Retrieval Curve
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Human capability to recall episodic memories depends on how much time has passed since the memory was encoded. This dependency is described by a memory retrieval curve that reflects an interesting phenomenon referred to as a reminiscence bump - a tendency for older people to recall more memories formed during their young adulthood than in other periods of life.
