This paper presents experimental and numerical investigations of liquid droplet/air two-phase flow through face masks. The study aims to provide a deeper understanding of the droplet filtration process, generate experimental data for modeling droplet/air two-phase flow across face masks, and develop and validate numerical models to simulate droplet motion through the mask and downstream. Droplet i
Group exhibition. 08.06.2025 – 20.07.2025 Walking, hiking, running, trekking, pilgrimage, escaping...The exhibition’s heart is the immediate experience of the landscape’s vastness, without infrastructure and with a sense of one’s own physical energy, but also of its limits. The exhibition All good things are wild and free. Wandern, pilgern, Spuren finden is about movement in nature and being moved
Group Exhibition. Participating artists: Daniel Boyd, Vija Celmins, David Horvitz, Bouchra Khalili, Judy Radul, Thomas Ruff, Carrie Mae Weems, Urban Subjects (Sabine Bitter, Jeff Derksen, and Helmut Weber), Paul Wong.Star Witnesses assembles works by a constellation of artists whose insightful observations of the cosmos bring new understandings of exploratory and migratory movements on Planet Eart
The aerodynamic effects of ice accretion on wind turbine blades has been studied using numerical methods. The ice accretion process on an aerofoil was simulated using RANS based simulations. The aerodynamic performance of the iced aerofoil was then investigated using several turbulence models, including both LES and DES. The results show that the shape of the ice has a profound influence on the li
The project developed a structured workflow for 3D scanning and documentation of artworks. This workflow covers every step from initial image capture to the final 3D model, ensuring consistency and quality in how artworks are digitized. It was presented to students as part of a course, giving them hands-on experience with 3D scanning equipment and photogrammetry software. Through practical exercis
De flesta batteridrivna prylar idag, som mobiltelefoner, bärbara datorer och elbilar drivs av litiumjonbatterier. Under de senaste åren har efterfrågan på batterier med hög energitäthet ökat kraftigt, vilket gjort att litiumjonbatterier används allt mer. Även om de är stabila kan de innehålla så mycket energi att ett fel kan bli riktigt allvarligt. Du har säkert hört talas om batterier som explodeLithium-ion batteries are widely used and remain the dominant energy storage technology for modern electronics and electric vehicles. Despite their widespread adoption, these batteries pose safety risks, including fire hazards and thermal runaway. One aspect that has received relatively little attention in current research is the formation and impact of fluorinated compounds during battery degrada
BACKGROUND: Brief Admission by self-referral (BA) was implemented in 2018 in Swedish child and adolescent psychiatric (CAP) inpatient care. This intervention empowers adolescents to self-admit at their own request for brief periods to prevent self-harm and suicidal crisis. As BA enhances healthcare user autonomy, it is a timely intervention to consider with the emerging human rights discourse and
Brief Admission by Self-referral (BA), a standardized crisis intervention for individuals with repeated self-harm or suicidal behavior, was adapted for adolescents from 13 years in Region Skåne, Sweden, in 2018. BA aims to offer access to support based on autonomy and has been associated with reduced need of emergency care. Interviews with adolescents and legal guardians have pointed to BA as valu
Women who have sex with women are a sexual minority often omitted from sexuality education curricula and school-based sexuality education. This study aimed to explore the sexuality education experiences of young women who have sex with women in German-speaking Switzerland. Semi-structured interviews were conducted with 15 participants (aged 18–25 years) and analysed using qualitative content analy
Denna avhandling undersöker överlevnad och långsiktiga utfall hos kritiskt sjuka COVID-19-patienter som vårdades på intensivvårdsavdelningar (IVA) i Skåne mellan maj 2020 och maj 2021. Vi syftade till att fylla kunskapsluckor genom att genomföra en prospektiv, multicenterstudie där vi följde 498 IVA-patienter under tre år och utvärderade dödlighet, funktionella, fysiska och psykiska utfall, samt hThis thesis investigates the survival and long-term outcomes of critically ill COVID-19 patients admitted to intensive care units (ICUs) in the Skåne region of Sweden between May 2020 and May 2021. We aimed to address knowledge gaps by conducting a prospective, multicentre cohort study following 498 ICU patients over three years, evaluating mortality, functional, physical, and mental outcomes, as
It is widely believed that Friedrich Hayek's first encounter with Gunnar Myrdal involved the latter's last-minute contribution, as a replacement for Erik Lindahl, to a Sammelband edited by the former in 1933, and that Hayek was lukewarm toward Myrdal and his ideas from the very beginning. Correspondence between the two shows that, in fact, their interaction about this contribution began two years
For Rosa Barba, cinema “allows time and space to vibrate, collapse, overlap, and extend.” Barba’s conceptual explorations of film probe historical records, personal narratives, and the sensory experience of celluloid, often by documenting natural landscapes and human-made changes to the environment. This installation spans 15 years of Barba’s work, featuring film, kinetic sculpture, and sound. A n
This thesis investigates the spectral properties of magnetic and nonmagnetic Schrödinger operators, which haveapplications in the distribution of superconductivity in type II superconductors and wave theory. The thesis beginswith an introduction to the main results in the field, giving a more detailed presentation for clarity. Next, we focuson the original research articles conducted by the author
This paper assesses the communication and the use of climate scenarios at the science–science and science–policy interface in Finland, Sweden and Norway. It is based on document analysis and stakeholder questionnaires. The questionnaires targeted three stakeholder groups, all engaged in the communication and the use of climate scenario information: climate scenario producers; impact, adaptation an
A physical lake model was employed to obtain a basis of discussing the impact of climate variability and climate change on the ecology of Lake Erken, Sweden. The validity of this approach was tested by running the PROBE-lake model for a 30-year period (STD) with observed meteorological data. The lake is adequately modelled, as seen in the comparison with actual lake observations. The validated lak
The increasing global demand for food will be met chiefly by increased intensification of production. For crops, this will be achieved largely by increased yields per area with a smaller contribution from an increased number of crops grown in a seasonal cycle. Production systems show a spectrum of intensification practices characterised by varying methods of site preparation and pest control, and
