The improvements in GPU hardware, including hardware-accelerated ray tracing, and the push for fully dynamic realistic-looking video games, has been driving more research in the use of ray tracing in real-time applications. The work described in this thesis covers multiple aspects such as optimisations, adapting existing offline methods to real-time constraints, and adding effects which were hard
Fluvial floods can cause significant damages and are expected to increase in magnitude and frequency throughout the twenty-first century due to global warming. Alongside hazard characteristics, damage potentials depend on exposure and vulnerability, which are changing in the wake of socio-economic developments. In the context of continuously evolving damage-causing factors, assessments of future c
Background: The drinking water in parts of Ronneby was heavily contaminated with perfluoroalkyl substances (PFAS) for decades. Although PFAS has endocrine-disrupting properties and may interfere with breastfeeding, the effects in populations with a point source of high exposure are unknown. Objectives: To investigate associations between high PFAS exposure and 1) initiation and 2) duration of brea
This study investigates how digital technology is used (or not used) in home care nursing, to identify challenges and opportunities that can move the digitalization of home care nursing forward. The use of digital technology in daily practices of home care nursing was analyzed based on semistructured interviews in four Swedish home care organizations. The results correspond to the two initial stag
Assessing effects of climate change on agricultural systems and the potential for ecological intensification to increase food security in developing countries is essential to guide management, policy-making and future research. ‘Push-pull’ technology (PPT) is a poly-cropping design developed in eastern Africa that utilizes plant chemicals to mediate plant–insect interactions. PPT application yield
This study aimed to estimate the healthcare costs of kidney transplantation compared with dialysis using a propensity score approach to handle potential treatment selection bias. We included 693 adult wait-listed patients who started renal replacement therapy between 1998 and 2012 in Region Skåne and Stockholm County Council in Sweden. Healthcare costs were measured as annual and monthly healthcar
Previous reports of mortality and morbidity in pediatric severe traumatic brain injury (TBI) vary considerably, with few population-based studies. Mortality rates from 3-33 % and varying morbidity have been reported, most commonly using the Extended Glasgow Outcome Scale (eGOS). The Lund concept is a treatment algorithm for severe TBI aiming at controlling intracranial pressure (ICP) by reducing c
We describe the case of a 30-year-old woman, who needed a formal report on her visual impairment to seek support from society. She was born preterm, and during her neonatal period, she suffered from bilateral intraventricular hemorrhage (IVH) grade 3, a condition that can cause cerebral visual impairment (CVI) due to damage to the retro-geniculate visual pathways. Individuals with such brain damag
The commercial production of bioethanol from lignocellulosic biomass such as wheat straw requires utilizing a microorganism that can withstand all the stressors encountered in the process while fermenting all the sugars in the biomass. Therefore, it is essential to develop tools for monitoring and controlling the cellular fitness during both cell propagation and sugar fermentation to ethanol. In t
BackgroundMost jurisdictions that allow euthanasia and assisted suicide (AS) regulate it through the medical profession. However, the extent and nature of how medicine should be involved are debated. Swiss AS practice is unusual in that it is managed by lay AS organizations that rely on a law that permits AS when done for nonselfish reasons. Physicians are not mentioned in the law but are usually
BACKGROUND: Breastfeeding in the public sphere is known to be experienced as a problem for many women. It has been shown to arouse negative feelings among the public, depending on the attitude of those in the immediate surroundings. This contributes to the fact that many women hesitate to breastfeed in public and prepare themselves for potential adverse comments.METHODS: An online survey was used
The effect of non-starch polysaccharides of whole unripe plantain flour (WUPF) on the starch hydrolysis rate provides information on the potential glycemic impact of the use of this flour to produce gluten-free foods. The aim of this study is to evaluate the effect of the non-starch polysaccharides (dietary fiber (DF)) present in the peel of unripe plantain flour on starch digestion, texture, and
This thesis seeks to answer what causes some governments to restrict foreign funding to domestic civil society organizations while others do not. These repressive measures have increased significantly in all regions of the globe recently and existing research has yet to provide an encompassing explanation for the trend. Considering that neither foreign funding or government repression are exactly
The study aims to investigate whether diversity can affect people's social intelligence. The study has been conducted with an experimental design, where two experimental groups were primed with a text describing a workplace with a high degree of diversity respectively non-diversity. A control-group read a neutral text. The texts were followed by the self-assessment test Tromsö Social Intellige
This thesis investigates the social position and political agency of women excombatants of the Farc-EP who laid down their arms after the 2016 peace agreement between the Colombian government and the Farc-EP. I show how, through the laying down of arms and reincorporation, women ex-combatants come to occupy a specific social position under historical and global power relations and intersecting for
The aim of this project is to analyse planetary boundary layer height (BLH) measurements from the Hyltemossa research station and find their dependence on seasonality, time of day, and air temperature. Further, investigation was made into the correlation between mass concentration of particulate matter with equivalent diameter<1μm (PM1) and black carbon (BC) aerosol and the BLH and how this varies
The combined threat of poor air quality, physical inactivity, and climate change is a major sustainability challenge for the transport sector. Numerous policy interventions may address this, yet technological improvement measures, including the isolated introduction of Emissions Zones, are currently over-emphasised. There is a lack of policy mix evaluations in the literature, particularly those in
Luminescence dating is widely used in combination with sedimentological analysis to reconstruct the landscape development of the Quaternary period. Here, quartz and K-feldspar measurements are used to date and evaluate the luminescence characteristics of sediments from seven sites of the lower part of the Velická valley (995-1250 m a.s.l.) in the High Tatra Mountains, Slovakia. The quartz and K-f
This paper sets out to investigate the construction of the municipality of Lomma in southern Sweden, north of Malmö; Sweden’s third-largest and Skåne’s largest city. Based on a dialectical and relational understanding of the construction of landscapes, Lomma is analysed in relation to Malmö and to its own surroundings. Through a historical investigation, a gathering of statistical data, and a docu
