Popular Abstract in Swedish Dagens samhälle är väldigt beroende av fordon av olika slag. Aldrig förr har människor rest till olika delar av världen, så mycket som idag. Den enorma mängden resors och transporter som sker varje dag är en tung belastning för vår natur. Bilar och lastbilar, som ökar i antal varje dag, släpper ut giftiga avgaser på vägarna och flygplan förbrukar enorma mängder fossilt Urban traffic involves frequent acceleration and deceleration. During deceleration, the energy previously used to accelerate the vehicle is mainly wasted on heat generated by the friction brakes. If this energy that is wasted in traditional internal combustion engines (ICE) could be saved, the fuel economy would improve. Today there are several solutions to meet the demand for better fuel economy

I avhandlingen studeras migration i form av anhöriginvandring till Sverige. I fokus ställs parförhållande där parets seriositet prövas av Migrationsverket.

Background: Early childhood environmental exposures, possibly infections, may be responsible for triggering islet autoimmunity and progression to type 1 diabetes (T1D). The Environmental Determinants of Diabetes in the Young (TEDDY) follows children with increased HLA-related genetic risk for future T1D. TEDDY asks parents to prospectively record the child's infections using a diary book. The pres

Background: Snake mitochondrial genomes are of great interest in understanding mitogenomic evolution because of gene duplications and rearrangements and the fast evolutionary rate of their genes compared to other vertebrates. Mitochondrial gene sequences have also played an important role in attempts to resolve the contentious phylogenetic relationships of especially the early divergences among al

During the last few years increased focus has been given to environmental and social issues due to worldwide changes in the weather and temperature, in some cases leading to natural disasters and dramatic changes in everyday life. Media and politicians have begun to address related problems, acknowledging the fact that human impact on nature is a real problem that poses as a threat to our future.

Today’s global competition forces manufacturing companies to re-evaluate their existing processes, technologies, manufactured parts and services in order to focus on strategic activities. The question whether to make or to buy goods or services represents a problem faced by many companies when deciding between keeping technologies/processes in-house or purchasing them from an outside supplier. In

Organising knowledge in a corporate environment : a case study at the development departments of Ecophon AB The purpose of this master's thesis is to investigate how three development departments of a technical firm could organise their collection of documents and information resources to improve their management of information. Three sets of questions have been posed: 1) How does the target

This examination paper will examine the reporting of the Husby riot during May of 2013 in four different Swedish national newspapers. I have taken a qualitative approach to analyse 40 newspaper articles that were written during the course of the riot. I chose to analyse articles that were written during the riot because I wanted to find out how the newspapers wrote about the riot and the people wh

The EU is accused of having a democratic deficit and one of the reasons for that is the low number of turnouts in democratic elections and referendums. Voter turnout is oneof democracy’s most important indicators of health as it shows to whatextent voters practice their democratic right in a representative democracy. Voter participation is thus an accept of the rules of the representative democrac

The spruce coneworm, Dioryctria abietella Denis & Schiffermüller (Lepidoptera: Pyralidae), is a major pest in spruce seed orchards in Europe. Initial work on its pheromone ecology reported significant attraction of males to (9Z,11E)-tetradecadienyl acetate (9Z,11E-14:OAc), but this compound appeared to be a very weak attractant in field trials. In this study, we show that a second female-produ

Background: The unanticipated difficult airway is a potentially life-threatening event during anaesthesia or acute conditions. An unsuccessfully managed upper airway is associated with serious morbidity and mortality. Several bedside screening tests are used in clinical practice to identify those at high risk of difficult airway. Their accuracy and benefit however, remains unclear. Objectives: The
