A Novel Anthropomorphic Phantom Composed of Tissue-Equivalent Materials for Use in Experimental Radiotherapy : Design, Dosimetry and Biological Pilot Study

The production of anthropomorphic phantoms generated from tissue-equivalent materials is challenging but offers an excellent copy of the typical environment encountered in typical patients. High-quality dosimetry measurements and the correlation of the measured dose with the biological effects elicited by it are a prerequisite in preparation of clinical trials with novel radiotherapy approaches. W

Timing of adverse events in patients undergoing acute and elective hip arthroplasty surgery : A multicentre cohort study using the Global Trigger Tool

Objective To explore timing in relation to all types of adverse events (AEs), severity and preventability for patients undergoing acute and elective hip arthroplasty. Design A multicentre cohort study using retrospective record review with Global Trigger Tool methodology in combination with data from several registers. Setting 24 hospitals in 4 major regions of Sweden. Participants Patients ≥18 ye

Women in Music - Are they absent from Western Music History?

Are women absent from Western Music History? This is a question of an apparent and easy answer; however, the reality differs. This issue prevails and only started to be discussed more seriously in recent years, since feminism has been a current on-going discussion through the world. In music, circumstances are seemingly slower to evolve still allowing discriminative actions. Through the analysis o

Empowerment and enablement and their associations with change in health-related quality of life after a supported osteoarthritis self-management programme - a prospective observational study

BACKGROUND: Osteoarthritis is a leading cause of disability worldwide. Current treatment supports coping strategies to improve health-related quality of life (HRQoL). The need to predict response to treatment has been raised to personalise care. This study aims to examine change in HRQoL from baseline to three and nine months follow-up after participating in a Supported Osteoarthritis Self-Managem

Drug interventions for prevention of COVID-19 progression to severe disease in outpatients : a systematic review with meta-analyses and trial sequential analyses (The LIVING Project)

Objectives To assess the effects of interventions authorised by the European Medicines Agency (EMA) or the US Food and Drug Administration (FDA) for prevention of COVID-19 progression to severe disease in outpatients. Setting Outpatient treatment. Participants Participants with a diagnosis of COVID-19 and the associated SARS-CoV-2 virus irrespective of age, sex and comorbidities. Interventions Dru

"Månen är ingen ost!": En idéhistorisk kandidatuppsats om Georg Borgström och rymdforskningen

"The Moon is not made of cheese!": A history of ideas thesis on Georg Borgström and the space research This thesis discusses and analysis Georg Borgström’s arguments against the space research program in the 1960s. It begins with his appearance in the Swedish radio on the 28 of August 1960 with the title “Mat eller månraketer” (“Food or moon rockets”). It then stretches throughout the 6

Data-Driven Adaptive Control of Unmanned Surface Vehicles Using Learning-Based Model Predictive Control

In this thesis, the subject of data-driven control of Unmanned Surface Vehicles (USVs) is explored. The control task is formulated through Nonlinear Model Predictive Path Following Control (NMPFC). System identification (SYSID) and Reinforcement Learning (RL) are employed to improve performance in a data-driven manner. The objectives were to assess the resulting controller’s path-following ability

Evidence of Unrecognized Indoor Exposure to Toxic Chlorophenols and Odorous Chloroanisoles in Denmark, Finland, and Norway

Production and use of chlorophenols (CPs) are being phased out around the globe, but with considerable lag in some highly populated countries. The process could be incentivized by leading countries sharing their experiences on problems that occurred, including the built environment. We previously reported that Swedish industry and authorities promoted CPs, including pentachlorophenol (PCP), as wooProduction and use of chlorophenols (CPs) are being phased out around the globe, but with considerable lag in some highlypopulated countries.

Evaluate Transformer model and Self-Attention mechanism in the Yangtze River basin runoff prediction

Study region: In the Yangtze River basin of China. Study focus: We applied a recently popular deep learning (DL) algorithm, Transformer (TSF), and two commonly used DL methods, Long-Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU), to evaluate the performance of TSF in predicting runoff in the Yangtze River basin. We also add the main structure of TSF, Self-Attention (SA), to the LSTM and G

The Complex Exhumation History of Jezero Crater Floor Unit and Its Implication for Mars Sample Return

During the first year of NASA's Mars 2020 mission, Perseverance rover has investigated the dark crater floor unit of Jezero crater and four samples of this unit have been collected. The focus of this paper is to assess the potential of these samples to calibrate the crater-based Martian chronology. We first review the previous estimation of crater-based model age of this unit. Then, we investigate

CW-laser radar for combustion diagnostics

A CW-laser radar system developed for combustion diagnostics is described. It is based on triangulation to attain range information. Some initial results from measurements in sooting flames are shown and some future perspectives are discussed.

The transformation of rainfall into runoff is one of the most important processes in hydrology. In the past few decades, a wide variety of automated or computer-based approaches have been applied to model this process. However, many such approaches have an important limitation in that they treat the rainfall-runoff process as a realization of only a few parameters of linear relationships rather th

Strain-specific metabarcoding reveals rapid evolution of copper tolerance in populations of the coastal diatom Skeletonema marinoi

Phytoplankton have short generation times, flexible reproduction strategies, large population sizes and high standing genetic diversity, traits that should facilitate rapid evolution under directional selection. We quantified local adaptation of copper tolerance in a population of the diatom Skeletonema marinoi from a mining-exposed inlet in the Baltic Sea and in a non-exposed population 100 km aw

Coronary microvascular dysfunction in Takotsubo syndrome and associations with left ventricular function

Aims: Coronary microvascular dysfunction (CMD) has been proposed as an important pathophysiological mechanism in Takotsubo syndrome (TTS). Our aims were (i) to evaluate and compare levels of CMD in patients with TTS and patients with ischaemia and no obstructive coronary arteries (INOCA) and (ii) to investigate associations between CMD and clinical parameters, left ventricular function, and corona

Radix Polygalae Extract Attenuates PTSD-like Symptoms in a Mouse Model of Single Prolonged Stress and Conditioned Fear Possibly by Reversing BAG1

Radix Polygalae (RP) has been used to relieve psychological stress in traditional oriental medicine. Recently, cell protective, antiamnestic and antidepressant-like effects were disclosed but the possible application of RP to post-traumatic stress disorder, in which exaggerated fear memory persists, has not yet been explored. For this purpose, the effects of RP on fear behavior was examined in a m

Creativity seems to be a concept exclusively for spiritual and eccentric people. Musicality ismostly associated with the idea of talent given from birth. However, these concepts areinevitable for the professional musician. The main objective of this thesis is to answer what iscreativity and musicality for a musician. This thesis concerns a clarification of these conceptsand tries to mold them into

Fagott och ergonomi. Att spela fagott utan skador.

Under mina år som fagottist så har jag de senaste fyra fem åren brottats med smärtor i framför allt min vänstra arm och axel. Skadorna uppstod av dålig hållning och spändhet som i sin tur ledde till överbelastning utav muskler. Vad finns det för metoder för att få bukt på smärtproblematik för mig som fagottist? Det här är den beskrivande delen av mitt examensarbete som handlar om hur jag under minDuring my years as a bassoonist, I have for the past four five years been afflicted with pain, especially in my left arm and shoulder. The injuries were caused by poor posture and muscular tension, which led to muscular overload. What are the methods for getting rid of pain problems for me as a bassoonist? This Bachelor thesis deals with how I have worked with ergonomic methods to reduce pain in m
