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-
On December 6-7, 2010, the International Desalination Association (IDA) presented its first Environmental Symposium, “Desalination and the Gulf: The Relationship between the Environment and Meeting the Region’s Water Needs.”Held in Manama, Kingdom of Bahrain under the Patronage of H.E. Eng. FahmiBin Ali Aljowder, Minister for Electricity and Water Affairs, this event was theresult of 12 months of
This thesis addresses micromechanical modeling of materials using computational homogenization. On this topic, theoretical and computational issues are discussed, and numerical investigations of different material systems are performed. The material systems considered are; metal matrix composites, metal sheets with stiff inclusions, metal sheets containing voids, sand with inclusions of gravel and
Background: Allergen avoidance is important in allergic asthma management. Nocturnal treatment with Temperature-controlled Laminar Airflow (TLA) has been shown to provide a significant reduction in the exposure to allergens in the breathing zone, leading to a long-term reduction in airway inflammation and improvement in Quality of life (QoL). Allergic asthma patients symptomatic on Global Initiati
Pacific Island countries are already experiencing severe impacts from climate change and these will likely increase in the future. In response, a plethora of climate change adaptation projects have been implemented across the region with the aim of assisting those most affected. Yet these projects have largely failed to reduce vulnerability to climate change in a meaningful way. This chapter addre
This thesis focusses on a nuclear spectroscopy experiment conducted to study α-decay chains stemming from isotopes of flerovium (element Z = 114). An upgraded TASISpec decay station was placed behind the gas-filled separator TASCA at the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt, Germany. The fusion-evaporation reactions 48Ca + 242Pu and 48Ca + 244Pu provided a total of 29 flerovi
The SRY (sex determining region Y)-box 11 (SOX11) gene, located on chromosome 2p25, encodes for a transcription factor that is involved in tissue remodeling during embryogenesis and is crucial for neurogenesis. The role for SOX11 in hematopoiesis has not yet been defined. Two genes under direct control of SOX11 are the class- III β-tubulin gene (TUBB3) in neural cells and the transcription factor
BACKGROUND: It is estimated that global dementia rates will more than triple by 2050 and result in a staggering economic burden on families and societies. Dementia carries significant physical, psychological and social challenges for individuals and caregivers. Informal caregiving is common and increasing as more people with dementia are being cared for at home instead of in nursing homes. Caregiv
HLA-DRB3*01:01 is a predisposing factor for human platelet antigen 1a (HPA-1a) immunization, which is responsible for most cases of fetal and neonatal alloimmune thrombocytopenia. The aim of this study was to investigate if the HLA-DRB3*01:01 allele imposes a dose-dependent effect on anti-HPA-1a levels and neonatal platelet counts. One hundred and thirty HPA-1a–immunized women were divided into 3
Calcium activation of the C-terminal domain of calmodulin was studied using 1H and 15N NMR spectroscopy. The important role played by the conserved bidentate glutmate Ca2+ ligand in the binding loops is emphasized by the striking effects resulting from a mutation of this glutantic acid to a glutamine, i.e. E104Q in loop III and E140Q in loop IV. The study involves determination of Ca2+ binding con
In yeast, a single cyclin-dependent kinase (Cdk) is able to regulate diverse cell cycle transitions (S and M phases) by associating with multiple stage-specific cyclins. The evolution of multicellular organisms brought additional layers of cell cycle regulation in the form of numerous Cdks, cyclins and Cdk inhibitors to reflect the higher levels of organismal complexity. Our current knowledge abou
Asteroid 4 Vesta is the only currently identified asteroid for which we possess samples in the form of meteorites. These meteorites revealed us that Vesta is a differentiated body and that its differentiation produced a relatively thin basaltic crust that survived intact over its entire collisional history. The survival of the vestan basaltic crust has long been identified as a pivotal constraint
This work concerned experimental studies of heat transfer in a light-duty diesel engine. Combustion is affected by several parameters, such as pressure, engine speed, mass of injected fuel and in-cylinder gas flow. These parameters are in turn affected by the combustion chamber geometry and fuel spray characteristics. At high load the exhaust heat was increased more than at high engine speed. Swir
A systematic study of cell membrane morphologies whose structure is governed by cubic symmetries has been performed. It is suggested that they are described by periodic cubic surfaces for which space filling surface foliations given by truncated Fourier series defined by the space groups is used as structural representations. Using this a method is developed which enables a direct ultrastructural
Popular Abstract in Swedish Olika arter av stora växtätare lever på platser spridda över nästan hela jordklotet. På många av dessa platser samlar vi människor data för att kunna skatta storleken på deras populationer. Anledningen till att detta görs varierar från plats till plats, det kan till exempel vara för att djuren är utrotningshotade, för att kunna bedriva nöjesjakt eller för att begränsa aLarge herbivores are monitored for various reasons in many areas around the world. Data from such monitoring can be of varying degree of detail and extent. Several studies have shown that we need extensive amounts of data with a high degree of detail to be able to understand anything from it. Nevertheless, data in the less detailed form of annual censuses of large herbivore densities and weather i
Objective: People who suffer from psychiatric illness have a more than doubled lifetime risk of acquiring an alcohol or drug use disorder. Furthermore, hazardous substance use impairs treatment outcomes and protracts the duration of illness among people with mental disorders. The aim of this study was to investigate substance use among people with psychiatric disabilities receiving municipality-ba
This paper investigates the greenhouse gas emissions from a Swedish wetland, constructed to decrease nutrient content in sewage treatment water. To evaluate the effect of the construction in terms of greenhouse gas emissions we carried out ecosystem-atmosphere flux measurements of CO2, CH4 and N2O using a closed chamber technique. To evaluate the importance of vascular plant species composition to
Quality of Life and long-term clinical outcome following robot-assisted radical trachelectomy. Objectives: To evaluate quality of life (QoL) and long-term clinical outcome following robot-assisted radical trachelectomy (RRT). Study Design: Prospectively retrieved clinical data were rereviewed on all women planned for a fertility sparing RRT for early stage cervical cancer at Skåne University Hospi
In many countries, the retirement age is postponed due to the global demographic change, and a larger amount of older people need to participate in working life. However, how and what measures and action proposals that could extend and increase employees’ voluntary and sustainable participation in working life have not entirely been investigated. The employer is responsible for enabling employees’
