To study Si and Fe based microwires coated with TiN we will need to design and test a cell on a tabletop X-ray setup called easyXAFS300. To do this we have developed a X-ray absorption spectroscopy spectroelectrical (XAS-SEC) cell. To test the easyX- AFS300 equipment on the soft part of the X-ray spectrum we have cooperated with Hang Yin to measure a Lanthanum halide compound Cs3LaCl6. These compo
Biosensors are powerful analytical tools, but their wider application is limited by the natural repertoire of available biological recognition elements. Allosteric transcription factors (aTFs) are attractive scaffolds for expanding this repertoire, but redesigning them to detect novel ligands has historically relied on directed evolution and structure-guided rational design, approaches that are la
Background and purpose: Breast cancer is the most common type of cancer among women in Sweden. The mortality can be significantly reduced if the breast cancer is detected at an early stage. Screening programs in Sweden are offered for all woman between 40-74 years, using conventional digital mammography (DM). Digital breast tomosynthesis (DBT) is superior to DM in terms of diagnostic accuracy, but
BACKGROUND AND PURPOSE The amino acid glutamate (Glu) is the primary excitatory neurotransmitter in human brain and is involved in both synaptic transmission as well as metabolic pathways. Dysfunction of glutamate concentration in the brain has been implicated in neurological diseases, such as epilepsy, Alzheimer’s disease, schizophrenia and essential tremor. Non-invasive detection of glutamate co
The last decades have seen great improvement in the treatment of children with brain tumours, 5-year survival has increased from 20% in 1950 to 80% in 2020. Current treatment can consist of a combination of surgery, chemotherapy and radiation therapy (RT). This improved chance of survival has placed increased focus on the quality of life of the survivors post treatment. RT increases the risk of ne
Magnetic resonance imaging (MRI) is a medical imaging modality that provides morphologi- cal and anatomical information about soft tissues. The development of new MRI methods, such as diffusion MRI (dMRI), has resulted in contrast mechanisms that further characterize the properties of tissue, such as microstructure. The development of a new contrast mechanism is typically associated with the deve
Studien syftar till att öka förståelsen för hur trafikstyrare upplever sitt arbete, handlingsutrymme och meningsfullhet vid olika nivåer av automatisering. Genom en kvalitativ, jämförande fallstudie undersöks två logistikterminaler med olika grad av automatisering: en terminal med låg grad (Halmstad) och en med hög grad (Växjö). Det empiriska materialet har samlats in genom semistrukturerade inter
Internationella investeringstvister skiljer sig från traditionella kommersiella skiljeförfaranden genom att statens samtycke till skiljeförfarande vanligtvis lämnas i förväg genom ett stående erbjudande i ett investeringsskyddsavtal. Ett bindande skiljeavtal mellan staten och den enskilda investeraren uppkom-mer först när en investerare som omfattas av erbjudandet accepterar detta, van-ligtvis genInternational investment disputes differ from traditional commercial arbitration proceedings in that the state’s consent to arbitration is usually given in ad-vance through a standing offer contained in an investment treaty. A binding arbitration agreement between the state and the individual investor arises only when an investor that falls within the scope of the offer accepts it, usually by init
Purpose: The purpose of this project was to examine how the degree of cancer suspicion evaluated by an AI system differs when examining repeated images of a realis=c breast phantom acquired with DM and DBT. This project is a part of a larger project to develop quality assurance systems and methods for AI systems in breast cancer screening. Background: AI systems are currently being introduced in b
Background and Aim: A new PET/CT scanner using BGO crystals was recently introduced in the clinic. Unlike scanners with LSO/LYSO crystals, this scanner does not include the time- of-flight (TOF) property, due to low timing resolution of BGO crystals. To compensate for the lack of TOF, the reconstructed images can be filtered with an AI model, called Precision DL (PDL), which has been trained on im
Purpose: The uterus and cervix are highly mobile organs that may be affected by motion in surrounding tissues during radiotherapy. In this study, the aim was to investigate intra-fraction motion of the uterus, cervix and organs at risk during a simulated treatment delivery of a magnetic resonance guided adaptive radiotherapy (MRgART) fraction and to evaluate its impact on the delivered dose. Mate
In the event of a radiological or nuclear (R/N) emergency, individuals and/or population groups may be exposed to radiation. For the average civilian, a potential but not confirmed exposure causes anxiety, even though it is unlikely that anyone except first responders or those close to the emergency site receives doses above negligible levels. Thus, there needs to be a way to separate the unexpose
Den svenska alunskiffern innehåller uran och andra ämnen som under senare år blivit aktuella för möjlig framtida utvinning. Höjda uranpriser, utvecklade brytningsmetoder och att regeringen åter gjorde det tillåtet att bryta samt utvinna uran har ökat intresset för uranbrytning i Sverige. Samtidigt är alunskiffer en komplex bergart som innehåller sulfidmineral och metallförande ämnen som kan utgöraSwedish alum shale contains uranium and other elements that in recent years have become more relevant for potential mining and extraction. Increasing uranium prices, new developments made within mining methods and the Swedish government making it legal to both mine and extract uranium have been contributing factors to the increased interest for uranium mining in Sweden. However, alum shale is a co

This project explores the intersection of Hi-Fi performance and interior aesthetics. Most systems today are cluttered because components are collected from various brands, and there is a lack of solutions that can house them as a single, cohesive unit. Through research and field studies, I found that some users expressed dissatisfaction with the traditional Hi-Fi look of racks and stands. Because
Syftet med detta arbete var att undersöka tangomusikens stilistiska drag så att jag som klassisk musiker får lättare att lära mig genren. Undersökningen skedde genom analys av YouTube-videos av olika tangoviolinister där jag studerade stildragen och tog till mig olika tekniker. Under två veckors tid förde jag även loggbok, där utvecklingskurvan noterades. Resultatet visar hur stildragen och teknik
This study examines how perceived customer value emerges in relation to Limited Edition (LE) products purchased in physical grocery stores. While previous research on LE products has primarily focused on high-involvement contexts such as fashion, luxury goods and technology, less attention has been given to how limited availability creates value in a routine low-involvement consumption setting. Th
This research paper seeks to understand the persistence of the Church Fund in contemporary Poland. The Church Fund, an entirely state-funded financing scheme for churches in Poland, is considered to be an archaic institution by popular opinion, and a contradiction to Poland’s constitutional mandate for secularism. This study analyzes the political debates within the Lower House of the Polish Gover
