Carbon-14 often dominates the effective dose to the public from authorized discharges from Swedish nuclear power plants (NPPs). In contrast to air-borne releases, water-borne discharges of 14C are currently not routinely monitored at Swedish NPPs. We have measured 14C in Fucus spp. (brown algae, used as bioindicators of 14C) in shallow waters at the Swedish west coast from 2020 to 2024. At Ringhal

The development of thermally stable nanoparticles is of utmost importance for applications like catalysis. In particular, Cu nanoparticles supported on metal oxides are easily deactivated under thermal treatments at low temperatures by sintering of the Cu nanoparticles. The formation of thermally stable nanoparticles is typically obtained with secondary drawbacks. In this study, an alternative met

Atomic vacancies are primordial for controlling the photocatalytic activity of perovskites. On the one hand, they are useful adsorption sites and help narrow the band gap, but they may also trap the electron-hole pair created after light absorption. Its precise control, although essential, is hardly achieved with traditional methods. In this work, an alternative experimental approach is employed t

This Master’s thesis is a study of the existence of yogaphobia in the swedish debate between the years 2012 and 2020 concerning the religious nature yoga. Via deconstructing misconceptions of yoga from a historical standpoint combined with the use of critical discourse analysis, the thesis explores the arguments found in news articles and submitters from the swedish newspapers Dagen and Världen id

Denna uppsats närmar sig svenskt plein-air måleri i Fontainebleau och inom konstnärskolonin Grèz-sur-Loing från slutet av 1800-talet genom längtans lins. Med utgångspunkt i temat nostalgi och apodemialgi – längtan hem och längtan att bort – undersöks landskapsmåleriet och hur det visualiserar teman om natur och modernitet. Denna tid av exil är en viktig punkt i svensk konsthistoria eftersom den haThis thesis examines late 19th-century Swedish plein-air painting in Fontainebleau and within the artists’ colony Grèz-sur-Loing through the lens of longing. Drawing on the theme of nostalgia and apodemialgia—longing for home and the longing to leave—it investigates how landscape painting visualizes themes of nature and modernity. This time of exile is an important point in Swedish art history as

In the late 17th century, a new style of decorations was developing in Sweden. Brutal flaming depictions of hell started covering the ceilings of the small parish churches. The trend would catch fire and over the course of the 18th century over 500 decorations were made in churches across western Sweden. This essay studies iconographic starting points for the style in the depictions the final judg

As a core component of an ITS, CAVs have garnered significant attention and expect to play an important role in enhancing traffic safety. To enable (future) practical deployment of CAVs, safety strategies must be incorporated into the control design. This includes, in particular, strategies for ensuring avoidance or mitigation of multi-vehicle collisions. Conventional control strategies exhibit so

Denna avhandling undersöker konceptet Rolling Magnet Energy Harvester (RMEH), en kinetisk energifångare, baserad på principerna för elektromagnetisk induktion. RMEH är utformad med fraktcontainrar i åtanke och utnyttjar energin från fordonets rörelser för att driva potentiella sensorer ombord. Det långsiktiga målet är att förbättra logistiken genom att tillhandahålla en enkel, hållbar och underhålThis thesis investigates the concept of a Rolling Magnet Energy Harvester (RMEH), a kinetic energy harvester based on the principles of electromagnetic induction. Designed with shipping containers in mind, the RMEH harnesses energy from the rolling motion of vehicles to power potential onboard sensors. The long term objective is to enhance logistics by providing a simple, sustainable, and maintena

Titel: Upplevelser och erfarenheter av fantomsensationer/-smärta vid amputation i nedre extremiteten, en kvalitativ intervjustudie. Introduktion: Fantomsmärta (PLP) och fantomsensationer (PS) är vanliga fenomen som amputerade upplever. Tidigare forskning visar stor spridning angående resultat och det återfinns en begränsad representation av upplevelser och erfarenheter av personer med påverkan av

Integrating learning-based techniques, especially reinforcement learning, into robotics is promising for solving complex problems in unstructured environments. Most of the existing approaches rely on training in carefully calibrated simulators before being deployed on real robots, often without real-world fine-tuning. While effective in controlled settings, this framework falls short in applicatio

Hazardous situations involving radioactive, chemical, and other dangerous materials pose significant risks to emergency responders. In such situations, robots can support civil forces in reconnaissance and mitigation. However, this requires the development of robotic systems with novel AI-based assistance functions, operation procedures, and raises new ethical and legal questions. To address these

Trajectory planning under kinodynamic constraints is fundamental for advanced robotics applications that require dexterous, reactive, and rapid skills in complex environments. These constraints, which may represent task, safety, or actuator limitations, are essential for ensuring the proper functioning of robotic platforms and preventing unexpected behaviors. Recent advances in kinodynamic plannin

From the perspective of the Swedish education system, rural knowledge does not seem to be particularly important. Many young people in rural areas have deep and important knowledge that is invisible in school and during school time, both to teachers and to the young people themselves.

Alternative food networks are increasingly promoted in policy, academic, and civil society discourses as pathways to sustainable and socially just food systems. However, their demographic homogeneity raises questions about their capacity to foster social inclusion. This study explores how Community Supported Agriculture (CSA) initiatives in Southern Germany navigate tensions between solidaritybase

Corporations now face dual pressures from climate change: the financial vulnerability and environmental accountability. As a response, corporate climate-related disclosure has evolved from voluntary sustainability pledges to a regulatory and market necessity in many regions including the Mainland China. This study explores climate-related disclosure behaviors and underlying motivations of Chinese

Climate change and environmental degradation are some of the most pressing crises of our time, however action is lacking. In order to create system transformation, the inner dimensions of sustainability need to be addressed: values, worldviews and qualities on an individual, collective and system level. Ecovillages seem to be spaces where the integration of internal and external sustainability occ

Glacier retreat driven by climate change has created intense water scarcity in Ladakh, India, threatening both the local agriculture and livelihoods. In response, Artificial Glaciers (AGs) have emerged as an adaptive strategy. This study examines the role of AGs in enhancing social resilience in the villages of Ursi and Igoo using the Six Attributes of Social Resilience framework. A mixed-methods

Bakgrund: Total höftplastik (THA) anses vara en effektiv behandling vid höftartros som förväntas resultera i minskad smärta och återställd funktion. Trots att många patienter får goda resultat, upplever en del en kvarstående smärta och funktionsnedsättning efter operationen. Rehabiliteringen efter THA varierar stort mellan olika vårdgivare och det finns en avsaknad av nationella riktlinjer för reh

Bakgrund: Ätstörningar, särskilt de två vanliga typerna, anorexia nervosa och bulimia nervosa, är komplexa och svårbehandlade sjukdomar med höga återfallsfrekvenser. De vanligaste behandlingarna består av psykologiska insatser och medicinering. Som en tilläggsbehandling inkluderas fysioterapeutinsatser. Anorexia nervosa och bulimia nervosa har en multifaktoriell orsak och den höga återfallsfrekven
