Wildfires are a major driver of ecosystem development and contributor to carbon emissions in boreal forests. We analyzed the contribution of fires of different fire size classes to the total burned area and suggest a novel fire characteristic, the characteristic fire size, i.e., the fire size class with the highest contribution to the burned area, its relation to bioclimatic conditions, and intra-
Divergence in sexually selected traits in allopatry should affect the degree and direction of hybridization. However, few studies have established the causes and targets of sexual selection during secondary contact. Common wall lizards (Podarcis muralis) from north-central Italy have highly exaggerated male sexual traits compared to populations in Western Europe. Using experimental populations, we
The objective of this study is to explore mechanisms for ignition and extinction for condensed-phase fuels via the use of a gas-fueled burner. Flames were generated with a porous 25 mm circular burner using mixtures of methane and propane with nitrogen. The procedure was to specify a set of mass fluxes of nitrogen-fuel mixture that corresponded to the flash- fire- and extinction points and for the
In the 20th century early management of acute pancreatitis often included surgical intervention, despite overwhelming mortality. The emergence of high-quality evidence (randomized controlled trials and meta-analyses) over the past two decades has notably shifted the treatment paradigm towards predominantly non-surgical management early in the course of acute pancreatitis. The present evidence-base
Vi vill karaktärisera fenomenet konceptbutik och undersöka hur den kan fungera som ett verktyg, för att bygga upp sitt varumärke. Konceptbutiker handlar om att ge upplevelser och erbjuda aktiviteter. Genom de fem sinnena kan man involvera kunden och ge den en upplevelse. Det optimala för en konceptbutik är att enbart sälja ett varumärke då dess syfte är att stärka det. Personalen och interiören ha
Syftet med denna masteruppsats är att undersöka människors upplevelser av att delta i flyktingmottagandet i Malmö under hösten 2015. Uppsatsen studerar motiveringar till varför volontärer beslutat sig för att hjälpa. Dessa analyseras främst genom Marcel Mauss teori om gåvosystem: volontärarbete, eller att hjälpa, ses som en gåva i uppsatsen. Motiveringarna analyseras också genom Erving Goffmans drThe purpose of this master’s thesis is to explore the experience of people who helped in the refugee reception in the city of Malmö, Sweden, in the fall of 2015. The thesis delves into the reasons and motivations to why volunteers decided to help. These are primarily analysed through Marcel Mauss’ gift-exchange theory where volunteering is seen as a gift; and secondarily by Erving Goffman’s dramat
According to the values of democracy, the governors should be held accountable for their actions and omissions by the governed. However, on a global level there is a deep deficit of democratic accountability. The Inter-Parliamentary Union, (IPU) whose members consist of almost all of the national parliaments in the world, claims to increase accountability within the UN system. This thesis uses the
Exciton dynamics in alternating copolymer/fullerene solar cell blends have been investigated using femtosecond transient absorption spectroscopy. The acceptor concentrations have been varied over a wide range. Experimental data, kinetic modeling and simulations, all indicate that the efficiency of exciton conversion to charges is 100% even at acceptor concentrations as low as 20 wt%. The reported
The presence of Fe-bound cyanide ligands in the active site of the proton-reducing enzymes [FeFe]-hydrogenases has led to the hypothesis that such Bronsted-Lowry bases could be protonated during the catalytic cycle, thus implying that hydrogen isocyanide (HNC) might have a relevant role in such crucial microbial metabolic paths. We present a hybrid quantum mechanical/molecular mechanical (QM/MM) s
The activity of the potent but highly toxic antifungal drug Amphotericin B (AmB), used intravenously to treat systemic fungal and parasitic infections, is widely accepted to result from its specific interaction with the fungal sterol ergosterol. While the effect of sterols on AmB activity has been intensely investigated, the role of membrane phospholipid composition has largely been ignored, and s
Accurate modeling of thermal power plant is very useful as well as difficult. Conventional simulation programs based on heat and mass balances represent plant processes with mathematical equations. These are good for understanding the processes but usually complicated and at times limited with large number of parameters needed. On the other hand, artificial neural network (ANN) models could be dev
In light of high turnovers and low retention a growing interest in finding solutions to retain Millennials is occurring. The mismatch between Millennials’ value systems and the organisational values systems are high and one of the reasons for Millennials to leave the organisation. Yet, fundamental questions about the relation between value systems of Generation Millennials entering the workforce a
The aim of this master’s thesis is to examine which competencies and qualifications Swedish government agencies require when hiring records managers today. Recently, the archival sector has encountered several challenges regarding technical solutions for electronic archiving. This thesis also attempts to address whether these changes affect the need for specific qualifications in records managers.
Food manufacturers and policy makers have been tailoring food product ingredient information to consumers' self-reported preference for natural products and concerns over food additives. Yet, the influence of this ingredient information on consumers remains inconclusive. The current study aimed at examining the first step in such influence, which is consumers' attention to ingredient information o
