In Sweden, it is every municipality’s responsibility to identify and risk evaluate disused landfills located within the municipality. The purpose of this study is to risk evaluate four disused landfills in Åstorps kommun, Scania, for which a risk evaluation hasn’t previously been done. In this study, the risk evaluation has been done by using a revised version of MIFO (Method of Surveying Contamin
Introduction: Decades of nuclear activities have polluted marine environments with transuranium actinides. Background: Brown algae have frequently been used as marine bioindicators of radioactivity, but current literature describing the sequential separation and determination of Pu and Am from brown algae matrices is sparse, and does not make use of recent extraction chromatographic resins such
Nigritella miniata is an alpine orchid species disjunctly endemic to the Eastern Alps and the Southeastern Carpathians. It is thought to have arisen only once through a hybridisation event between now extinct ancestors. Questions of interest are whether N. miniata survived in few or many isolated refugia in the Eastern Alps during the Last Glacial Maximum (LGM), and their relationship with the pop
In order to study and evaluate the care provided at the Intensive Care Unit (ICU), an accurate model to assess severity of illness and predict patient mortality based on admission data is required. Since 1983, the Simplified Acute Physiology Score (SAPS) based on logistic regression (LR) has become one of the international standards for this purpose and is used in Sweden for adults. While being a
Urbanisation in Beirut has led to a situation where the city suffers from a severe lack of green public space—Lebanon’s capital have ended up with some of the least amount of public green space per capita in the world. The lack of green surfaces and vegetation in Beirut contributes to the city’s Urban Heat Island (UHI)—a phenomenon where an urban or metropolitan area traps waste heat and end up si
The amount of wind turbines in Sweden has more than doubled in the last five years. Wind turbines can affect birds directly, by causing fatalities and indirectly, through habitat destruction, disturbance and barrier effects resulting from turbine construction and operation. To increase understanding of how this rapidly expanding form of energy harvesting affects avian communities in Sweden large,
Air pollution has become a major worldwide concern due to the high levels of air pollutants emitted from industrial and traffic related activities. Exposure to air pollution has been linked to various negative health effects, ranging from asthma to chronic illnesses. Consequently, analyzing air pollution data has become an essential tool for giving insight about the potential health effects. Spati
Rapporten är en del av kursen Brandteknisk Riskvärdering vid Lunds Tekniska Högskola. Syftet är att analysera och utvärdera personsäkerheten på Confidencen, Ulriksdals Slottsteater, vid händelse av brand. Confidencen är byggnadsminnesmärket och är Sveriges äldsta rokokoteater som bedriver teater- och operaverksamhet. Publiken består till mestadels av äldre personer där byggnaden rymmer maximalt 25This rapport is a part of the course “Brandteknisk riskvärdering” given at Lund University of Technology. The purpose of this report is to evaluate the fire safety and evacuation possibilities of the theater Confidencen with the focus on personal safety of the people in the building. If necessary, suggestions of improvements in the fire safety will be provided. Confidencen is the oldest Rococo the
Arlanda flygplats är en av Nordens största flygplatser, vilket gör att personbrandskyddet är väldigt viktigt. Ett platsbesök genomfördes på Terminal 4 på Arlanda vid projektets början i syfte att göra en brandteknisk riskvärdering av byggnaden. Under platsbesöket samlades information in om potentiella riskkällor och möjligheterna att utrymma undersöktes. Detta resulterade i flera potentiella brandArlanda is one of northern Europe’s largest airports servicing 18,4 million travelers in 2022. Ensuring the safety of everyone moving through or working within the building requires a large-scale safety and security infrastructure. This report narrows its focus to one of the older parts of Arlanda, terminal 4. The aim of this project is to evaluate the fire protection focusing on the safety of the
Diamine oxidase (DAO) is an enzyme involved in the regulation of cell proliferation and the immune response. This enzyme performs oxidative deamination in the catabolism of biogenic amines, including, among others, histamine, putrescine, spermidine, and spermine. The mechanistic details underlying the reductive half-reaction of the DAO-catalyzed oxidative deamination which leads to the reduced enz
Group A Streptococcus (GAS)causes infections ranging from mild sore throats to severe invasive disease; however, no licensed vaccine is currently available. In this thesis, the author leverages streptolysin O (SLO), an important GAS protein and therapeutic/vaccine target, as a model system to develop a multimodal protein mass spectrometry(MS) strategy. Through an integrated approach of MS-based pr
Aims: Increased common carotid artery (CCA) intima media thickness (cIMT) is a well-known risk factor for cardiovascular morbidity and mortality. cIMT thickening has been described in patients with repaired aortic coarctation (CoA), but data on mechanism and clinical relevance in this population are scarce. Our aim was to gain mechanistic insights into cIMT thickening of patients with repaired CoA
Cryptic genetic differentiation is being increasingly documented in birds and other organisms using genome-wide variation. A recent example of cryptic genetic differentiation in a widespread species with conserved morphology is the northern house wren Troglodytes aedon. We found that, despite extremely similar morphology and no documented vocal differences, the two subspecies of the northern house
Background: Cardiovascular autonomic dysfunction is a major complication in a large proportion of patients with long coronavirus disease (LC). As one of the most typical phenotypes of cardiovascular autonomic dysfunction, postural orthostatic tachycardia syndrome (POTS) is commonly observed as a sequelae of coronavirus disease infection. Objective: This study aimed to develop and test a 24-hour el
Deposition of phosphorus (P) is important for the nutrient supply to forests and open land but also contributes to the eutrophication of surface waters. Deposition to open land can be measured as bulk deposition while deposition to forests cannot be measured directly, due to internal circulation of P within forest canopies. This study aimed to quantify the total deposition of P to open land and fo
Brandskum som innehåller per- och polyfluorerade ämnen (PFAS), på engelska Aqueuous Film Forming Foam (AFFF), är en av de främsta källorna till föroreningarna i Sverige. Grundvattenförorening orsakat av användandet av AFFF under brandövningar har undersökts i Kallinge, Blekinge. I området har grundvattnet använts som råvatten vilket resulterat i förhöjda halter av PFAS i dricksvattnet. Liknande faAqueuous Film Forming Foam (AFFF) containing Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS) is one of the major sources of groundwater contamination in Sweden. Groundwater contamination caused by the use of AFFF in correlation to fire training events was investigated in Kallinge, Sweden. At the site groundwater was previously used as a drinking water source consequently affecting the inhabit
Atomic vacancies are primordial for controlling the photocatalytic activity of perovskites. On the one hand, they are useful adsorption sites and help narrow the band gap, but they may also trap the electron-hole pair created after light absorption. Its precise control, although essential, is hardly achieved with traditional methods. In this work, an alternative experimental approach is employed t
Perfluoroalkyl and polyfluoroalkyl substances (PFASs) are becoming an increasingly global concern. PFASs are highly fluorinated organic chemicals that represent a serious risk for environmental and human health. Due to their toxicological impact, PFASs are now included in several emission regulations. Even if the global level of PFASs use is decreasing much of present concentrations in the environ
