For model-based quantitative reconstructions of past vegetation cover on the scale of landscapes, pollen productivity estimates (PPEs) are key input parameters. In this study, we employed a random sampling strategy to collect moss polsters at 20 sites in Changbai Mountain, northeastern China. A detailed vegetation survey within 1000-m radius around each sampling point was carried out and digitized
A measurement of elastic deeply virtual Compton scattering gamma*p --> gamma p using e(+) p and e(-) p collision data recorded with the HI detector at HERA is presented. The analysed data sample corresponds to an integrated luminosity of 306 pb(-1), almost equally shared between both beam charges. The cross section is measured as a function of the virtuality Q(2) of the exchanged photon and the ce
Many buildings, both new and old, suffer from moisture-related problems, with negative consequences on health, costs for rebuilding and lost confidence in the building industry. These problems could have been avoided if moisture issues had been focused on and dealt with throughout the building process. A method for including moisture safety in the building process has therefore been developed. The
Problem: Niche co-evolution deals simultaneously with the number and the character of species within a community. How can a community of predators and prey adaptively radiate to fill available niches? How many niches are there? And, can adaptive speciation at evolutionary branching points successfully fill the niches of the ESS? Model features: We use a predator–prey model with one fitness-genera
Background: Old age at diagnosis is associated with poor survival in colorectal cancer (CRC) for unknown reasons. Recent data show that colonoscopy is efficient in preventing left-sided cancers only. We examine the association of Tumor Node Metastasis (TNM) classes with diagnostic age and patient characteristics. Methods: The Swedish Family-Cancer Database has data on TNM classes on 6,105 CRC aden
Direct ozone (O-3) injection is a promising flue-gas treatment technology based on oxidation of NO and Hg into soluble species like NO2, NO3, N2O5, oxidized mercury, etc. These product gases are then effectively removed from the flue gases with the wet flue gas desulfurization system for SO2. The kinetics and mixing behaviors of the oxidation process are important phenomena in development of pract
In this paper the design and demonstration of a 7 nm(3) h(-1) integrated steam reforming based hydrogen production unit using a Fischer-Tropsch diesel is reported. The system design is discussed in detail, including the fuel processor itself as well as the hydrogen purification and results from stand-alone operation of the combined unit operations is reported. Further, the results of an integratio
We present a high-resolution and independently dated multiproxy lake sediment record from the paleolake at Les Echets in southeastern France that displays synchronous changes in independent limnic and terrestrial ecosystem proxies, in concert with millennial-scale climate oscillations during the last glacial period. Distinct lake-level fluctuations, low lake organic productivity, and open, treeles
Currently, the majority of spent batteries are not recycled but become part of the household waste in many countries, especially in China which is the largest producer and consumer of batteries. This is due to many reasons, including the lack of governmental policies to encourage and facilitate battery return and recycling. In that context this research was designed to investigate the attitudes an
Biomass derived gases produced via gasification, pyrolysis, and fermentation are carbon neutral alternative fuels that can be used in gas turbines, furnaces, and piston engines. To make use of these environmentally friendly but energy density low fuels the combustion characteristics of these fuels have to be fully understood. In this study the structure and laminar burning velocity of biomass deri
Where conservation resources are limited and conservation targets are diverse, robust yet flexible priority-setting frameworks are vital. Priority-setting is especially important for geographically widespread species with distinct populations subject to multiple threats that operate on different spatial and temporal scales. Marine turtles are widely distributed and exhibit intra-specific variation
Objective: The aim of this study was to analyse the occurrence of neonatal early onset group B streptococcal (EOGBS) disease relative to maternal body mass index (BMI). Method: A cohort of Swedish parturients with an early pregnancy BMI registered was investigated. Data were retrieved from population-based registers during 1997-2001, (n = 344 127, elective caesarean section excluded). Medical reco
The reduction of the (A root 5x root 5)R27 degrees surface oxide on Pd(100) and Pd75Ag25(100) surfaces by CO has been investigated by high-resolution X-ray photoelectron spectroscopy in combination with kinetic analysis using the Avrami-Erofeev theory. For both surfaces we observed faster reduction with increasing temperature. Kinetic analysis indicates that the reduction process is phase boundary
All notified MRSA cases in SkAyenne County have been followed since 2000. We have investigated the MRSA epidemiology over time, method of acquisition, whether some spa types are more prone to spread, and/or cause more infections, and the connection between spa type and country of acquisition/origin. All cases between 2000 and 2010 were included. Infection or colonization and the presence of PVL ge
Land degradation has a negative effect on agriculture, food security and ecosystems. It severely impacts the livelihood of the many people directly depending on agriculture around the world. Drylands are some of the most vulnerable areas around the world. Population increase and climate change add strain on the food production of these areas, making them especially vulnerable to land degradation.
Den digitala ekonomin innebär stora utmaningar för nationella och internationella skattesystem. Den Europeiska unionen (EU) vill bemöta dessa utmaningar genom lösningar på unionsnivå som involverar samtliga medlemsstater. Om det inte går att uppnå harmonisering på området är risken att medlemsstaterna konkurrerar med varandra genom regleringskonkurrens. Den Europeiska kommissionen har presenterat National and international tax systems face significant challenges due to the digitalisation of the economy. The European Union (EU) argues that these challenges must be met with solutions at union level that involve all Member States. If no harmonisation is achieved, there is a risk that the Member States will compete with each other through regulatory competition. The European Commission has mad
This thesis evaluates the hazards occurring during extinguishing of a passenger car fire in order to obtain recommendations for the Swedish rescue services on how to extinguish a passenger car fire in a safe and environmentally friendly manner. The thesis evaluates both acute and long term toxicity of combustion products as well as extinguishing agents, regarding both human health and the environm
This bachelor thesis deals with the change in the Swedish government's stance on migration politics during the refugee crisis in the autumn of 2015. In early September Swedish Prime Minister Stefan Löfven held a speech calling on the rest of Europe to do more in order to help refugees. Two months later the situation had changed and the government changed it’s migration politics to the “EU mini
Since the early 1990s, NATO and Russia have cooperated in a number of areas. Relations grew stronger, even though there were clear contradictions in various fields. But the cooperation continued until the beginning of 2014 when Russia through violence annexed the Crimean peninsula. The action had the consequence of NATO suspending any and all cooperation with Russia and relations are at the worst
This dissertation investigates the function of the sea in contemporary British and Irish literature, focusing on the following three novels: Dermot Bolger’s Temptation (2000), John Banville’s The Sea (2005), and Ian McEwan’s On Chesil Beach (2007). The analysis is divided into two main parts, where the sea is considered in its roles as a setting and as a symbol. The former section starts with a su
