Bakgrund: Antalet människor som är på flykt i världen ökar och att vara på flykt kommer ofta med omfattande förändringar i individernas liv. Att etablera ett nytt socialt liv, anpassa sig till en ny miljö eller att uttrycka emotionella behov kan vara särskilt utmanande. Skapande aktiviteter har en stor potential att främja känslouttryck och erbjuda ett nytt socialt sammanhang där man genom engagemBackground: The number of displaced people is increasing, involving major changes in the lives of individuals. It can be challenging to establish one's social life, adapt to a new environment or express emotional needs. Creative activities hold great potential to promote emotional expression and offer a new social context where individuals can express themselves emotionally and experience a se

It is shown that mean conjunction times calculated from the conjunction tables and calculated from the tables of mean solar and lunar longitudes differ by 14 minutes in Peter Apian's Astronomicum Caesareum. It is also shown that Apian used an extra longitude correction for the geographical longitude correction between Toledo and Ingolstadt for the mean longitude and longitude of argument of the Mo

The electromechanical properties of hafnium zirconium oxide fluorite (Hf0.5Zr0.5O2, HZO) remain largely unexplored despite its widespread use as a ferroelectric in CMOS-compatible devices. Here, we demonstrate that electrostriction-driven phase instability enables a giant pseudo-piezoelectric response in epitaxial HZO thin films. Above a critical field of 24 kilovolts per centimeter, field-induced

We developed a novel apparatus based on a lead-glass calorimeter that can measure the flux of high-energy electrons or photons. Our detector uses the electromagnetic shower leakage from the beam dump, where the particles are disposed of at the beamline's end. A prototype of such a calorimeter was set up at the FLASHForward experiment at DESY. We show that it can measure the electron bunch charge w

Wakefield accelerators driven by linear accelerators (linacs) benefit from linearly ramped bunch current profiles, which can increase energy efficiency and reduce induced correlated energy spread in the accelerated bunch. Linacs often employ chicane bunch compressors and higher-harmonic radio-frequency cavities to tune the bunch current profiles.

Energy-transfer efficiency is an important quantity in plasma-wakefield acceleration, especially for applications that demand high average power. Conventionally, the efficiency is measured using an electron spectrometer, an invasive method that provides an energy-transfer efficiency averaged over the full length of the plasma accelerator. Here, we experimentally demonstrate the use of the excess lEnergy-transfer efficiency is an important quantity in plasma-wakefield acceleration, especially for applications that demand high average power.

Treatment decisions in lung cancer rely on comprehensive molecular and histological characterization, but the limited amount of tumor tissue available from diagnostic procedures remains a major challenge. In this proof-of-concept study, we investigated whether preserving small bronchoscopic tumor specimens in RNAlater enables integrated molecular and histological profiling. Bronchial forceps biops

The Inner Tracking System of the ALICE detector at CERN’s Large Hadron Collider is to be upgraded by replacing the three innermost layers with novel, wafer-scale stitched sensors. By bending the silicon sensors around the beam pipe, an almost fully self-supporting structure is created, enabling the reduction of each layers material budget from the current 0.36 % X_0 to 0.09 % X_0. The reduction of

Invasive alien species are plants and animals introduced to new areas by humans with a negative effect on various habitats. In Sweden the shrub Rosa rugosa has recently been put on a national list of species that should be addressed as a cause of concern. Rosa rugosa was moved by humans to Europe in the 17th hundreds, with the intention of using it as an ornamental plant. It has also been used as

The regulatory oversight in Sweden is based on chapter 26 of the Swedish environmental code, together with national environmental goals. Even though there are guidelines the municipalities carry out the oversight in different ways. The aim of this study is to examine how municipal environmental supervision in the waste sector is carried out, and to analyse which legal and organisational factors en

The Baltic Sea is a semi-enclosed basin characterized by its brackish water and unique biodiversity. However, it is also one of the most polluted seas in the world and is exposed to multiple environmental stressors, including eutrophication, overfishing, and climate change. Freshwater and coastal browning have been observed across the Northern Hemisphere, although the cause and dynamics of brownif

In 1986, the nuclear disaster in Chernobyl caused large-scale land abandonment which resulted in one of the largest unintended experiments of passive rewilding, yet no study has combined remote sensing land cover classification using a pre-disturbance baseline with vegetation productivity analysis across the full Chernobyl-Palieski Reserve under an explicit rewilding framework. This thesis qu

The emergence of ultra-fast fashion (UFF) has become an increasingly discussed phenomenon in recent years. However, there is limited research on what differentiates the UFF business models from the rest of the sector, or how emerging textile policy will affect the business model. Exnovation, or the deliberate phasing out of certain practices, has received increasing attention in research, and has

The EU is considered a global leader in sustainability and environmental politics and have influenced other markets to adopt similar practices, through trade relations rather than political pressure; this is conceptualized as the Brussels Effect. In 2025 the EU implemented the Omnibus package, revising several corporate reporting frameworks and narrowing their scope. This study examined how the re

Climate change poses increasing challenges to all life on Earth. Ecosystems and biodiversity are driven towards unsustainable states. There is a growing consensus that cities play a crucial role in leading the climate transition, and municipalities have been identified as key actors. The research field draws attention to barriers between policy and practical implementation, such as legal and finan

This study investigates spatiotemporal changes in eelgrass (Zostera marina) extent in Skälderviken between 2006 and 2023, and compares these changes with riverine nutrient loads, modelled water-quality indicators and depth distribution. Eelgrass extent was mapped from orthophotos and high-resolution satellite imagery for 2006, 2010, 2016 and 2023. Annual nitrogen and phosphorus loads from Rönne å

This study examines challenges and solutions for biodiversity conservation in privately owned forests in Skåne in southern Sweden. The study is conducted in response to the increasing number of threatened forest-dependent species due to production-oriented forestry. Since private forest owners are a central part of forest management in Sweden, their priorities and management decisions directly inf

Climate change increasingly affects urban areas through heatwaves, flooding and extreme weather events, while previous research shows that these impacts disproportionately affect vulnerable and marginalized groups. Therefore, integrating justice into climate adaptation planning has become an increasingly important issue in both research and policy. This study analyzes how four justice dimen sions

Locknekratern i Jämtland, centrala Sverige bildades för cirka 455 miljoner år sedan i ett grunt epicontinentalt hav när en meteorit med en diameter på 600 meter slog ner i den Baltiska skölden. Nedslaget skapade en 7.5 km bred inre krater i det proterozoiska kristallina urberget som överlagrades av skiffer och kalksten. Eftersom den ursprungliga morfologin hos nedslagskratrar snabbt eroderas på joThe Lockne impact structure in Jämtland, central Sweden, was formed approximately 455 Ma in a shallow epicontinental sea when a bolide 600 meters in diameter struck the Baltic Shield. This event excavated a 7.5 km wide inner crater in the target rocks at the site, comprised by Proterozoic crystalline basement overlain by shale and limestone. Since the original morphology of impact craters are rapi
