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
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
Aim: The aim was to scrutinize the report in March 2023 that Sweden’s excess mortality was lowest in 2020–2022 compared with other European Union and Nordic countries, a report that received great national and international attention. Study design: Comparison of excess mortality in Sweden and Norway. Methods: Excess mortality for 2020–2022 was calculated for Sweden and Norway, the country with per
Background: Individuals with type 2 diabetes (T2D) are at increased risk of developing cardiovascular disease (CVD) which necessitates monitoring of risk factors and appropriate pharmacotherapy. This study aimed to identify factors predicting emergency department visits, hospitalizations, and mortality among T2D patients after being newly diagnosed with CVD. Methods: In a retrospective observation
The pHrodo with an “off–on” response to the changes of pH has been widely used as a fluorescent pH probe for bioimaging. The fluorescence off–on mechanism is fundamentally important for its application and further development. Herein, the sensing mechanism, especially the relevant excited-state dynamics, of pHrodo is investigated by steady-state and time-resolved spectroscopy as well as quant
Objective: To investigate the prevalence of diabetes retinopathy and evaluate the factors influencing its occurrence both at the onset of type 2 diabetes (T2D) and three years into its duration. Design: Retrospective population-based study. Setting: Data was retrieved from Regional Healthcare Information Platform in Region Halland 2016–2020. Subjects: Patients 35-75 years old in Region Halland rec
Background: To date, studies investigating the association between pre-biologic biomarker levels and post-biologic outcomes have been limited to single biomarkers and assessment of biologic efficacy from structured clinical trials. Aim: To elucidate the associations of pre-biologic individual biomarker levels or their combinations with pre-to-post biologic changes in asthma outcomes in real-life.
As humanity faces multiple mutually-reinforcing social-ecological crises, rhetoric on transformations abounds. However, transformations are normative, politically-contested processes that risk perpetuating, or even exacerbating, the ecological and socio-economic crises of today. We argue that transformations should seek to enhance human and non-human well-being within the planetary boundaries; a g
Hip and knee arthroplasties are mostly successful procedures; however, patient injuries may occur and should be reported to Löf, the Swedish patient insurance. This study investigated the incidence of patient injuries after primary total hip and knee arthroplasty in the Swedish regions, differences in incidence depending on annual surgical volume, and types of approved injuries. Approved patient i
Importance: Despite increased use of antibiotic-loaded bone cement (ALBC) in joint arthroplasty over recent decades, current evidence for prophylactic use of ALBC to reduce risk of periprosthetic joint infection (PJI) is insufficient. Objective: To compare the rate of revision attributed to PJI following primary total knee arthroplasty (TKA) using ALBC vs plain bone cement. Design, Setting, and Pa
Background: Remaining pain and functional limitations may cause dissatisfaction in patients after total knee arthroplasty (TKA). Furthermore, anxiety and depression are associated with remaining postoperative symptoms and dissatisfaction. We investigated if patient-reported anxiety or depression increased the risk of dissatisfaction 1 year after TKA in patients who improved in pain or function. Me
Background: All-cause and AIDS-mortality in Europe has been decreasing between 1996 and 2020. However, regional differences as well as their drivers remain unclear. This study investigates mortality differences and their drivers, including usage of and response to antiretroviral therapy (ART) and active tuberculosis (TB), among people with HIV across Europe. Methods: People with HIV enrolled in Eu
Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most prevalent chronic liver disease globally, and can lead to hepatocellular carcinoma (HCC), a leading cause of cancer-related death. We aimed to determine the extent to which MASLD is an increasing cause of HCC in Sweden and to determine clinical characteristics associated with underlying MASLD. Using the Swedish quality re
Microsoft Word - Odla majs.docx Majs Zea mays Fakta om växten • Majs började odlas i Sydamerika och Mexiko för tusentals år sedan. Christoffer Columbus tog majsen till Europa. • Majs hör till växtfamiljen gräs, precis som vete och ris. De här tre sädesslagen är de viktigaste och mest odlade grödorna i världen. • På majsen sitter han- och honblommor på olika ställen på samma planta. • Av ma
