The aviation industry is a contributor to the global greenhouse gas emissions. Moving away from fossil-based fuels has proven to be more difficult than expected. One possibility for the aviation industry is the development of sustainable aviation fuels (SAFs), produced from renewable sources such as biomass and waste. Certain problems have been discovered with using SAFs, however. The fuels are us
I denna rapport redovisas populationstrender för 178 svenska fågelarter för åren 1975–2013. Fåglarna har räknats på vintern och på sommaren enligt strikt standardiserade metoder. Sommar- respektive vinterpunktrutter har räknats sedan 1975, i huvudsak i södra Sverige. Standardrutterna räknas också på sommaren (sedan 1996) men täcker hela Sverige. Vintern 2012/2013 räknades 130 000 fåglar av 128 artWe present the results of the Swedish Bird Survey, run by the Department of Biology, Lund University, as a part of the National Monitoring Programme of the Swedish Environmental Protection Agency. The results for 2013 include data from 580 winter point count routes in 2012/2013 (38th winter), of which 295 were carried out during the Christmas/New Year count and 273 summer point count routes (39th
Accurate precipitation data are crucial for hydrological modelling and rainwater runoff management. Precipitation variability exists through a wide range of spatial and temporal scales and cannot be captured well using sparse rain gauge networks. This limitation is further emphasised for urban and mountainous catchments, especially under global warming, causing an increased frequency of extreme ev
Quantification of land surface-atmosphere fluxes of carbon dioxide (CO2) and their trends and uncertainties is essential for monitoring progress of the EU27+UK bloc as it strives to meet ambitious targets determined by both international agreements and internal regulation. This study provides a consolidated synthesis of fossil sources (CO2 fossil) and natural (including formally managed ecosystems
Ongoing consumption of fossil-based fuels generates a massive amount of greenhouse gases. This may lead to global warming that is currently threatening human society and wild animal habitats. Hydrogen is an energy carrier with the highest energy content per weight compared to other all fuels and no carbon dioxide is released when combusted. Thermophilic bacteria belonging to the genus of Caldicell
Background: Haematopoietic stem cells expressing the CD34 surface marker have been posited as a niche for Mycobacterium tuberculosis complex bacilli during latent tuberculosis infection. Our aim was to determine whether M tuberculosis complex DNA is detectable in CD34-positive peripheral blood mononuclear cells (PBMCs) isolated from asymptomatic adults living in a setting with a high tuberculosis
Radiotherapy (RT) after mastectomy has been part of the treatment for early breast cancer since the 1940s. The treatment reduces the risk of loco-regional recurrences, but implies risk of late side effects that can begin decades after RT. Aims of the thesis were: - To analyse the long term effects of postmastectomy radiotherapy and systemic treatment for 1100 stage II breast cancer patients in t
The eminent dilemma around the relationship between the increasing world population, the need of new fuel sources and environment issues has raised great awareness in the last decades. The European Parliament has set common goals such as the reduction of the greenhouse gases by 20 % by the year of 2020, followed by the requirement of at least 10 % of the fuel has to be biofuel. An adjacent issue i
Background: Animal studies suggest that the arginine vasopressin (AVP) system plays a role in glucose and fat metabolism, but data from humans are limited. Method and results: We analysed plasma copeptin (copeptin), a stable C-terminal fragment of the AVP pro-hormone in the large, Swedish, population-based cohort Malmö Diet and Cancer Study Cardiovascular Cohort (MDC-CC, n=6103). Using baseline
En delägare som innehar kvalificerade andelar i ett fåmansföretag omfattas av de s.k. 3:12-reglerna som innebär att utdelning och kapitalvinst till viss del ska beskattas i inkomstslaget tjänst i stället för i inkomstslaget kapital. Om delägaren ska överlåta företaget kan han eller hon inom lagens gränser vidta en rad åtgärder för minska och senarelägga skatten som ska betalas för kapitalvinsten. A shareholder who holds qualified shares in a closely held company is subject to a special set of tax rules named the 3:12 rules. These rules lead to shareholders’ dividends and capital gains to some degree being taxed as labor income instead of capital income. If the shareholder should transfer the company, it is possible – within the boundaries of the law – to make some arrangements to reduce an
Popular science summary: Healing: what we can learn from white mice Stem cells are a cell type responsible for building the body. They are the ancestor cells from which all the cells making up the body’s tissues are created. Stem cells play an important role in maintaining the body in shape by repairing damages as they occur during life. We believe that if we had a better understanding of how t
Abstract Toxic cyanobacterial blooms can form in both freshwater and marine environments, which could threaten the health of human beings and animals. The genera that are known for causing the scums in freshwater are Anabaena, Microcystis, Cylindrospermopsis and Planktothrix. In order to control lake water quality and minimize the potential health risk associated with the cyanobacterial blooms, th
Abstract Agricultural intensification is causing a worldwide loss in biodiversity, and organic farming has been proposed as a valid method for preserving it. Studies have shown that organic farming increases species abundances, however the taxonomic breadth of communities may be an additional important biodiversity measure which is not affected by study intensity or sample size. The aim of this s
In Sweden, the tramway was introduced in the late 19th century as horse tramways. Entrepreneurs around the country saw advantages of the new mean of transport which, due to low frictional resistance could transport a large amount of passengers with low traction force. In the beginning of the 20th century the horses were replaced by electric motors and the tramway spread to more cities. The entry o
Recent droughts from 2017 to 2020 induced significant stress on woodland canopies across eastern Australia, resulting in widespread tree browning and mortality. However, the trajectory of post-drought recovery remains unclear, with uncertainty about whether canopy conditions are improving or continuing to decline. Identifying the key local environmental and climatic factors influencing drought-ind
Silk fibers offer untapped internal structures to template the formation of nano-objects and active coatings. So far, access to all or part of the internal and organized structures has been a significant challenge. The aim of the thesis is, therefore, to identify and exploit silk templating ability to create value-added multifunctional hybrid materials with enhanced conductive and catalytic proper
The Entangled Media Geographies of the Nordics: Contemporary Scandinavian Production Practices through the Prism of Audio-visual Nordic Noir.Olof Hedling, Lund UniversityAlthough predominantly contemporary in its outlook, this paper attempts to grabble with a particular development in media history, namely the gradual de-nationalization, or, perhaps more accurately, the increasingly transnational
Abstract. This study presents a comprehensive assessment of the meteorological conditions and atmospheric flow during the Lagrangian-type "Hill Cap Cloud Thuringia 2010" experiment (HCCT-2010), which was performed in September and October 2010 at Mt. Schmücke in the Thuringian Forest, Germany and which used observations at three measurement sites (upwind, in-cloud, and downwind) to study physical
Background: Vascular-targeted photodynamic therapy, a novel tissue-preserving treatment for low-risk prostate cancer, has shown favourable safety and efficacy results in single-arm phase 1 and 2 studies. We compared this treatment with the standard of care, active surveillance, in men with low-risk prostate cancer in a phase 3 trial. Methods: This randomised controlled trial was done in 47 Europea
