Popular Abstract in Swedish Nästan alla träd i våra skogar lever i samspel (symbios) med svampar. Många av dessa är ”vanliga” svampar, sådana som vi är vana vid att se och plocka i naturen, (exempelvis soppar, kremlor, riskor, flugsvampar och kantareller) men det finns också de som inte bildar fruktkroppar, eller har fruktkroppar som vi inte ser. Fruktkropparna, de som kan hamna i svampkorgen, är Elevated nitrogen (N) deposition is an environmental problem that can affect plants and microorganisms, which are vital for the terrestrial N and carbon (C) cycles. This thesis has investigated the response of ectomycorrhizal fungi (EMF) to increased N deposition. Ectomycorrhizal fungi form mutualistic interactions with the roots of woody plants, including almost all boreal and temperate forests

Background: A hip fracture is a common cause of morbidity, functional disability, and decreased health-related quality of life (HRQOL). With demographic changes showing a growing proportion of older people, hip fractures will be an increasing challenge for healthcare services in the future. Hip fractures threaten the independence of individuals in their everyday lives.

Whole blood is rich in information about the physical state of an individual and is routinely used in a variety of clinical and research applications. In this thesis, the use of a microfluidic technique called acoustophoresis for separation of different blood components is explored. Acoustophoresis uses an ultrasonic standing wave field to manipulate cells in a microfluidic device. Cells within th

The French court dress Le grand habit, worn at many European courts during the 18th century, was introduced in Sweden in the 1740’s by the crown princess Lovisa Ulrika, sister to Fredric II of Prussia. The robe de cour remained the official ceremonial dress for women at the Swedish court until Gustavus III launched the Swedish National Costume in 1778. The four robes de cour preserved in the Royal

In laser-wakefield acceleration (LWFA), a femtosecond laser pulse is tightly focused in a gas to intensities exceeding 1018 W/cm2 . The laser radiation ionizes the medium and excites a plasma wave that travels behind the laser pulse. Electrons can be trapped in the oscillations in the plasma density, where electric fields of the order of several hundreds of GV/m accelerate them to relativistic ene

The global society is dependent on transportation to function and a big part of these transports are driven by an internal combustion engine. Heavy-duty vehicles utilizes conventional diesel combustion is a combustion concept where the fuel is often ignited during the injection event and while it gives a high combustion efficiency, the combustion mode is also characterized by high emission of NOx

Popular Abstract in Swedish Avhandlingen innehåller tre empiriska studier som analyserar hur livsmedelsmarknaden påverkas av åtgärder för att fördjupa den europeiska ekonomiska integrationen. Fokus är på det svenska EU-medlemskap och det kontinuerliga arbetet med att harmonisera livsmedelslagstiftningen. Det senare har stor relevans för livsmedelsmarknaden eftersom det har funnits och fortfarande This thesis consists of three papers, all of which deal with the effects of deepening European integration on the food and beverage industry and market. The focus is on the period after Swedish EU membership in 1995. The last two papers use firm data and focus on the Swedish food and beverage industry, an industry which is an interesting case study as it was considered to be protected from foreign

This thesis describes an extended flamelet approach for modelling of soot formation in turbulent hydrocarbons diffusion flames. Detailed chemical kinetic mechanisms are used to compute species concentrations, temperature, density and soot formation rates as functions of flamelet coordinates in the space of mixture fraction and scalar dissipation rate. An ensemble average based on a presumed probab

Popular Abstract in Swedish Denna avhandling ger en introduktion till laser-plasma acceleratorer, vilket även utgör ämnet för de vetenskapliga artiklar som ingår i avhandlingen. Det är en ny typ av acceleratorer som utnyttjar mycket kraftfulla lasrar för att accelerera elektroner och protoner. Partikelacceleratorer används för att ge partiklar hög rörelseenergi, vilket kan utnyttjas för många olikThis thesis presents experimental results related to laser plasma accelerators. These rely on very different principles from conventional particle accelerators. They are able to accelerate particles over a very short distance and produce synchrotron x-rays at the same time, potentially providing a compact particle accelerator and x-ray source for many future applications. The laser pulses used in

This thesis explores how older people construct meaning, use and make sense of three kinds of robots in their homes. The exploration is undertaken in empirical studies of an assistive robot, an eHealth system, and robotic vacuum cleaners. The research draws on data collected through interviews and observations of older people in relation to three robots. The results show that older people’s domest

The savanna ecosystem is one of the most dominant and complex terrestrial biomes, deriving from a distinct vegetative surface comprised of co-dominant tree and grass populations. While these two vegetation types co-exist functionally, demographically they are not static but are dynamically changing in response to environmental forces such as annual fire events and rainfall variability. Modelling s

Abstract:This doctoral thesis is addresses two topics in integrated circuit design: multiband direct conversion cellular receivers for cellular frequencies and beam steering transmitters for millimeter wave communication for the cellular backhaul. The trend towards cellular terminals supporting ever more different frequency bands has resulted in complex radio frontends with a large number of RF in

We evaluate the capability of the global atmospheric transport model TM5 to simulate the boundary layer dynamics and associated variability of trace gases close to the surface, using radon (222Rn). Focusing on the European scale, we compare the boundary layer height (BLH) in the TM5 model with observations from the National Oceanic and Atmospheric Admnistration (NOAA) Integrated Global Radiosonde

Syftet med denna studie är att bidra till en ökad förståelse för individens säkerhet, men även att diskutera om utredarna i den svenska utredningen Ordningsvakter och Väktare (Ds 2003:50) tar tillräckligt mycket hänsyn till perspektivet av individens säkerhet och den påverkan som utredningen kan ha på denna.

Bakgrund: I flera havsnära kommuner finns attraktiv mark med vattennära och central lokalisering som utnyttjas ineffektivt. Hur kan man ta tillvara på denna mark och hur har tidigare exploateringar genomförts? Utgångspunkten för studien var att hitta en bättre användning för mark i hamnområden vilket födde exjobbsidén. Svårigheter i exploateringsprojekt inom hamnområden har tidigare varit förknippBackground: In several seaside municipalities, there are attractive pieces of land with central location, near the water, that are inefficiently used. How is the land utilized and how has previous exploitation projects been carried out? The starting point for the study was to find a better use for ground areas in harbours, which gave birth to the idea for this master thesis. Difficulties in earlie

Turbulent heat transfer over rough surfaces is crucial in natural and industrial processes, yet it has received less attention than that of momentum transfer. Recently, research in this field is rapidly growing, driven by advancements in computational methods, the role of surface roughness in meteorology, and the growing use of Additive Manufacturing technologies for energy and thermal management

Den ökade erosionen till följd av havsnivåhöjningen, orsakad av klimatförändringarna, som läggs på den redan förekommande erosionen kommer få stora konsekvenser. Mark kommer att försvinna där det i dagsläget finns bostäder, vägar, järnvägar, hem för djur- och växtliv, osv. Dessutom leder erosionen till att mark som idag finns tillgänglig för nybyggen i kustnära områden inte längre kommer att existThe globally accelerating sea-level rise poses a problem in coastal areas through, e.g., the erosion of sandy beaches. Due to this, buildings, infrastructure, and other values can be lost, making the future shoreline position important to project in coastal management. One location with historical erosion problems is Ystad municipality in southern Sweden, where the erosive problems are probable to
