Fertility restoration using autologous testicular tissue transplantation is relevant for infertile men surviving from childhood cancer and, possibly, in men with absent or incomplete spermatogenesis resulting in the lack of spermatozoa in the ejaculate (non-obstructive azoospermia, NOA). Currently, testicular tissue from pre-pubertal boys extracted before treatment with gonadotoxic cancer therapy
The development of Quantum Simulators, artificial platforms where the predictions of many-body theories of correlated quantum materials can be tested in a controllable and tunable way, is one of the main challenges of condensed matter physics. We introduce artificial lattices made of lead halide perovskite nanocubes as a new platform to simulate and investigate the physics of correlated quantum ma
Uncertainty analysis should be an integral part of conducting a scientific investigation of the damaging human health effects of exposure to chemicals. Sources of uncertainty related to limitations in knowledge are present in all steps of a such risk assessment, i.e. the hazard identification, hazard characterization and exposure assessment. The purpose of uncertainty analysis is to evaluate the c
Interactions between physical bodies constantly affect their properties. This thesis presents a theoretical study on the effects of interaction in few-body nanowire quantum dots. The focus is to a large extent on a phenomenon called Wigner localization, and how this, as well as other interaction effects, can be identified in an experiment by transport spectroscopy and by thermopower measurements.
This dissertation, based on six included papers, theoretically investigates properties of quantum few-particle systems. An overview of related experimental research - ultra-cold trapped dilute gases, and electrons in quantum dots - is given, followed by a description of some of the studied many-particle phenomena - Bose-Einstein condensation, quantized vortices, Wigner localization and the Tonks-G
The articles included in this thesis centre on what can be called the normative basis of risk analysis. Since risk analyses are decision procedures, they should adhere to norms of rational decision-making, and this they do. Most risk analysis schemes are built on a notion of the decision theoretic maxim that the goal of every decision is to maximize expected utility. However, for some thirty years
Previous studies have shown a correlation between nature connection and pro environmental behavior. Simultaneously, urbanisation amongst other causes has led to decreased human contact with nature. However, local outdoor recreation is considered an option for spending time in nature despite living in urban areas. Drawing from the above, there are reasons to study whether local outdoor recreation c
This study shows that several beneficial aspects of climate adaptation in Swedish municipalities can be linked to the United Nations’ sustainable development goals. In doing so, the study also exhibits that the sustainable development goals could serve as a good tool to aid in maximizing social, environmental and economic benefits when planning and executing climate adaptation measures. A claim th
Local acceptance is key when implementing climate technologies. One necessary technology to mitigate climate change is land-based Carbon Capture and Storage (CCS). In Denmark, earlier experience with the technology ended in shutdown due to local resistance. But now CCS plays a significant role in the Danish climate reduction goals; without CCS the goal won't be met. The academic field is very
Increased average temperatures, rising sea levels and heat waves are some examples of the consequences of climate change. Cities are particularly vulnerable to climate-related events due to their structure and lack of green and blue spaces causing negative impacts on both the environment and public health. Children are one of the most sensitive groups to heat waves and they spend plenty of time in
Pollutant emissions to the environment caused by human activity is a worldwide problem. This can occur due to residential fires which are often connected to loss of human lifes and belongings, as well as environmental damage. Residential fires canlead to emissions of pollutants that can be released to the air, water and soil. In this study, the level of soil contamination caused by residential fi
With climate change resulting from a history of uncontrolled greenhouse gas emissions, all parts of society now need to take action - maybe most importantly the private sector. Since 2015 the Science Based Targets (SBT) initiative has committed over 5000 companies worldwide to heavily reduce their total emissions at a pace that scientists deem necessary for average global temperature rise to stay
Biodiversity is declining all over the world due to human activities. This is alarming since human survival is dependent on biodiversity and the ecosystem services nature provides. In urban areas, private gardens have been pointed out as important agents for nature conservation, at the same time as they function as expressions of the owner’s identity and personal values. This study investigates wh
This study investigated how pollinators are affected by plant protection products (PPP), what type of PPPs strawberry farmers used and what knowledge they had about these products. To investigate this, a literature review and a survey was conducted. The questionnaire was sent to 70 Swedish strawberry farmers of which 11% participated in the study. The results of the survey shows that all (6) straw
To reduce vulnerability and enhance resilience to climate change, climate adaptation measures are needed that can contribute to a more resilient society. Cross-sectoral collaboration and the involvement of multiple actors are central to a coherent and comprehensive approach to climate adaptation. The aim of this study is to contribute to an increased understanding of how policy labs can be used a
Climate change, manifested through flooding, landslides, and erosion, poses increasing challenges for the built environment. In Sweden, nearly 90 percent of the population resides in urban areas, which were planned under past climatic conditions and are often difficult to adapt retroactively. Spatial planning plays a crucial role in addressing this issue, with municipalities holding central respo
The land use, land-use change, and forestry sector (LULUCF) has historically been rather unregulated. Recent political developments have put pressure on countries to implement practices that increase net greenhouse gas (GHG) removals and improve the state of carbon sinks. One of these political developments is the European Union’s (EU) LULUCF Regulation, which as of now obligates Member States (MS
