Light absorbing carbonaceous aerosols produced from combustion span over a range of physicochemical properties. Soot is the most recognized species in this category and its formation process involves gradual maturation from amorphous young soot with a high hydrogen-to-carbon-ratio toward mature soot aggregates. In this work, the optical response of a single particle soot photometer (SP2) to electr
The important role of fire in regulating vegetation community composition and contributions to emissions of greenhouse gases and aerosols make it a critical component of dynamic global vegetation models and Earth system models. Over 2 decades of development, a wide variety of model structures and mechanisms have been designed and incorporated into global fire models, which have been linked to diff
The Global Land-Atmosphere Climate Experiment-Coupled Model Intercomparison Project phase 5 (GLACE-CMIP5) is a multimodel experiment investigating the impact of soil moisture-climate feedbacks in CMIP5 projections. We present here first GLACE-CMIP5 results based on five Earth System Models, focusing on impacts of projected changes in regional soil moisture dryness (mostly increases) on late 21st c
Nitrogen (N) is a key element in terrestrial ecosystems as it influences both plant growth and plant interactions with the atmosphere. Accounting for carbon–nitrogen interactions has been found to alter future projections of the terrestrial carbon (C) cycle substantially. Dynamic vegetation models (DVMs) aim to accurately represent both natural vegetation and managed land, not only from a carbon c
Popular Abstract in Swedish Vårt mål var att förstå och fördjupa kunskapen om de mekanismer som kontrollerar värme- och masstransport vid stekning av djupfrysta hamburgare. Avhandlingen redovisar bl. a. hur olika faktorer som val av köttråvara, sönderdelningen av köttet, diametern på hamburgaren och tillagningstemperatur bestämmer värme- och massöverföring i hamburgaren under tillagning. TemperatuThe aim of the present work was to gain better understanding of the mechanisms controlling heat and mass transfer during thermal processing of beefburgers. The effects of different factors such as the chemical composition and comminution of the meat raw material, the pan temperature and the meat patty diameter on the characteristics of heat and mass transfer were studied. The evolution of the char
Popular Abstract in Swedish Transportsektorn står för 63% av Sveriges använding av kol, olja och gas. Biobränslen som etanol, biodiesel och biogas står bara för 6.8% av energin som används för nationella transporter, biogas står för 12% av detta. Ökad produktion av biobränslen för transproter behöver inte betyda minskad produktion av jordbruks- och skogsråvaror för annat. Dels kan restprodukter anBiofuels are currently produced from agricultural crops, and an increasing use of crops for this application is expected in the EU in the years to come. The dominating crops cultivated in the EU for biofuel production today have a relatively large environmental impact. The European Energy Agency has identified several lignocellulosic crops, including industrial hemp, as more sustainable potential
Responsibility to protect är en princip som för första gången formades år 2001 av International Commission on Intervention and State Sovereignty. Sedan dess har principen utvecklats stegvis genom olika handlingar och dokument vilka varit påverkade av mellanstatliga relationer och av de uppkomna händelser där mänskliga rättigheter stått på spel. Syftet med detta arbete har varit att försöka klargöThe responsibility to protect is a principle formulated in 2001 by the International Commission on Intervention and State Sovereignty. Since then, it has gradually been developed on the basis of different acts and documents that were influenced by inter-state relations and the agreements concerning human rights. This thesis attempts to explain what the responsibility to protect actually implies a

Problembeskrivning: Aktörerna inom detaljhandeln har idag problem med hög kapitalbindning och hård konkurrens. För den enskilde detaljisten kan det vara ödesdigert att göra felinköp av större varupartier, dels på grund av den finansiella risken, dels på grund av problemen med att upprätthålla förtroendet hos konsumenterna. Syfte: Syftet är att beskriva och utveckla samarbetet mellan detaljist och
Popular Abstract in Swedish Stroke (även kallat slaganfall) är den tredje vanligaste dödsorsaken efter hjärtsjukdom och cancer i stora delar av världen. Strokesjukdomen består av blodpropp (hjärninfarkt), blödning i hjärnan (intracerebral blödning) eller blödning i dess hinnor (subaraknoidal blödning). Stroke definieras enligt WHO som snabbt påkomna neurologiska symptom (t.ex. förlamning, talsvåriBackground: Stroke is a major cause of death and disability. Investigations of the epidemiological trends for stroke might result in better understanding of stroke pathogenesis and prevention. Methods: The trends of first-ever stroke incidence and survival over 3 time periods (1983-85, 1993-95 and 2001/2002) in Lund-Orup health care district were studied. The first 2 study periods were retrospect
Reaching intended effects of the covid-19 pandemic vaccination is dependent on both coverage rates and time. Without vaccine mandates in Sweden, communication strategists have become essential to succeed. Vaccine hesitancy is complex with reasons differing on an individual level. This makes mass communication suboptimal, but also mainly what is used due to practical reasons. Consequently, understa

Populärvetenskaplig sammanfattning: Världens hav är av största betydelse för jordens klimat. Totalt är 71 % av jordens yta täckt av vatten. Den mesta av den inkommande solstrålningen, som når jordens yta, upptas av haven. Havens värmekapacitet och cirkulation medför att de både kan lagra och transportera denna värme, innan den återgår till atmosfären och strålar tillbaka ut i rymden. Den termohaThe world ocean is of great importance for the Earth’s climate system, and affects climate in a number of ways. Approximately 71 % of the Earth’s surface is covered by oceans. Most of the solar radiation is received by the ocean. The heat capacity and circulation of the ocean makes it possible to both store and redistribute this heat before it returns to the atmosphere and radiates back into space
The extreme 2018 hot drought that affected central and northern Europe led to the worst wildfire season in Sweden in over a century. The Ljusdal fire complex, the largest area burnt that year (8995 ha), offered a rare opportunity to quantify the combined impacts of wildfire and post-fire management on Scandinavian boreal forests. We present chamber measurements of soil CO2 and CH4 fluxes, soil mic
