There is a significant knowledge gap in the current state of the terrestrial carbon (C) budget. Recent studies have highlighted a poor understanding particularly of C pool transit times and of whether productivity or biomass dominate these biases. The Arctic, accounting for approximately 50% of the global soil organic C stocks, has an important role in the global C cycle. Here, we use the CARbon D
The elemental composition of the St. Louis aerosol has been investigated at rooftop sites in south and central locations in the city as part of the August, 1973 field season of the Regional Air Pollution Study of the U.S. Environmental Protection Agency. Sampling by 5-stage cascade impactor with backup filter permits analysis by proton-induced x-ray emission (PIXE) of size fractions of aerodynamic

The thesis examines what the drama and the production tell about the unrest of those times and about political and ethical antagonisms
Objective Type I interferons (IFN) drive systemic lupus erythematosus (SLE) pathogenesis. Some patients develop neutralizing IFN autoantibodies (anti-IFN ab), which theoretically could modify disease activity. We aimed to determine the prevalence of anti-IFN ab in patients with SLE, identify the age and when during the disease course of anti-IFN ab emerge, and assess their association with organ d
Mental wellness environments a thesis on how a village-like district within a city context supports mental wellbeing. The awareness of mental health and wellbeing has lately increased, revealing rising levels of stress and anxiety. In addition, after the COVID‑19 pandemic people became more reliant on social media and remote work, which changed how we interact with local communities and exposed m
Popular Abstract in Swedish Populärvetenskaplig sammanfattning på svenska Abort är ett av de vanligaste kriurgiska ingreppen i Sverige. 1989 var aborttalet för hela landet 21.5 per 1000 kvinnor i åldern 15-24 år. Storstäderna Stockholm, Göteborg och Malmö har i många år haft det högsta aborttalen, vilka var för dessa 1989 28.4, 27.0 respektive 27.8. De aktuella studierna omfattar de 1466 kvinnorIn Sweden between 32-38,000 women annually elect to terminate pregnancy by means of induced abortion, though their reasons are still not well understood. The purpose of these studies, carried out at the Department of Obstetrics and gynecology and of Community Medicine at University Hospital, Malmö, was to elucidate the incidence of induced abortion in an urban population, with special emphasis on
Our world is experiencing accelerated ecological destruction and social injustices on different scales and multiple levels. Unchecked economic growth has been criticised as causing this since the 1970s, but the dominant sustainable development paradigm has perpetuated the belief that economic growth and environmental protection can go hand-in-hand. In response degrowth has emerged in the last deca
Uppsatsen behandlar hur AI-genererade konstnärliga och litterära alster hanteras upphovsrättsligt i Sverige och i EU. Eftersom USA generellt är ledande i den tekniska utvecklingen på området kan den rättsliga regleringen där påverka Sveriges konkurrensmöjligheter. Därför görs även jämförelser med de amerikanska diskussionerna. Verk med mänsklig delaktighet skyddas om AI:n har använts som verktygThis essay examines how the intellectual property rights of AI-generated artistic and literary works are handled in Sweden, the EU and the United states. If an AI has been used as a tool for the user to create, the copyright legislation is satisfactory. There are already however, machines that can generate music, text and paintings without any, or with minimal, human input. Completely AI-generated
This thesis is about the conceptualization of persistence of physical, middle-sized objects within the theoretical framework of the revisionary ‘B-theory’ of time. According to the B-theory, time does not flow, but is an extended and inherently directed fourth dimension along which the history of the universe is ‘laid out’ once and for all. It is a widespread view among philosophers that if we acc
Popular Abstract in English Extraction of valuable substances from plants using a solvent has been practised in many fields. One of the examples is making coffee or tea using hot water. In agricultural and food industry, there are tons of wastes containing valuable compounds that can be extracted before they go to incineration. Extractions are usually performed in organic solvents such as methanolPressurised hot water is an environmentally friendly alternative to hazardous organic solvents such as methanol and heptane. One of the many applications of using pressurised hot water extraction (PHWE) is to extract polyphenols from plants. The challenges in PHWE lies with the optimisation of extraction yield. One factor that is often overlooked is the risk of degradation of thermally labile comp
In the last decades, the role of warehouses has increased due to wider product range, emphasis on shorter lead times and constant changes in customer demand. The increased demands forces companies to improve their warehousing operations for better service level and decreased costs. Different technology solutions like WMS and RFID are currently available for supporting this improvement. However, th
This master's thesis sets out to explore information literacy in a contextualized learning environment with emphasis on students at a vocationally oriented program in the Swedish upper secondary school. The concept of information literacy is widely discussed and furthermore a common subject for research within the field of Library and Information Science. Information literacy can be described
Aerosols affect precipitation by modifying cloud properties such as cloud droplet number concentration (CDNQ. Aerosol effects on CDNC depend on aerosol properties such as number concentration, size spectrum, and chemical composition. This study focuses on the effects of aerosol chemical composition on CDNC and, thereby, precipitation in a mesoscale cloud ensemble (MCE) driven by deep convective cl
Vegetation is an important part of the environment but may be subjected to disturbance in areas close to coal mines. This results in a slowing of the rate of biomass growth, which is caused by fading of vegetation. Simultaneously, carbon stored in vegetation is constantly released, weakening vegetation ability to act as a carbon sink. Indirect release of carbon during coal mining processes is diff
Biologiskt flyktiga organiska ämnen (BVOCs) är spårämnen förutom CO2 och CH4 som produceras och släpps ut av växter. Termen innehåller tusentals olika ämnen i varierande former och storlekar och där ämnena har korta atmosfäriska livstider. Några av de vanligaste BVOC grupperna kallas isopren, monoterpener och sesquiterpener. Växterna använder sig av BVOCs för att kommunicera med varandra, attraherBiogenic volatile organic compounds (BVOCs) are trace gases other than CO2 and CH4 produced and emitted by the vegetation. The group consists of thousands of compounds in various shapes and sizes and with short atmospheric lifetimes. Some of the most common BVOC groups are called isoprene, monoterpenes and sesquiterpenes. For the plant, the emission of BVOCs is used for plant communication, attrac
Purposes: It has earlier been suggested that dietary supplementation with N-3 Polyunsaturated Fatty Acids (n-3 PUFAs) could have beneficial effects on cardio- vascular system patients with type 1 diabetes mellitus (DM1). Whether the benefit also extends to coronary circulation has not been yet investigated.Methods: In a double-blind placebo controlled cross-over study, 33 children with DM1 duratio

This thesis investigates the role of interior design elements, especially artwork, in way-searchers’ wayfinding and orientation in hospital environments. The thesis considers the way-searcher’s background and the impact of cultural belonging, occupation, memories, aesthetic preferences, and language, and the influence that such factors might have on the perception of the hospital environment and i
Small birds are hot creatures with an average body temperature of 40° Centigrade, and so must burn energy at a formidable rate to stay warm. This becomes quite the challenge in winter when birds are 40-50 degrees warmer than outside for extended periods, even in comparatively mild regions such as Scotland. Thus, the little bird in winter must spend most of the day either feeding or searching for
