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
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
This thesis deals with epitaxial growth and optical properties of semiconductor nanowires with implications and insights about materials for solar cells. The chapters leading up to the papers give a broader background and an introduction to the field and include nanowires and their synthesis, semiconductor properties, solar cell operational principles, light interaction with a nanowire array, and
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
Den främsta orsaken till en ökad växthuseffekt anses idag bero på en högre koncentrationav koldioxid i atmosfären. Sedan den industriella revolutionen harmänniskan påverkat mängden koldioxid i atmosfären genom aktiviteter så somförbränning av fossila bränslen, avskogning, förändringar i markanvändning, samtcementproduktion. För att kunna motverka framtida klimatförändringar krävs enfördjupad kunskThis thesis focuses on the development and application of efficient mathematicaltools for estimating and modelling the exchange of carbon dioxide (CO2) between the Earth and its atmosphere; here referred to as the global CO2 surface flux.There are two main approaches for estimating the CO2 flux: Processed based(bottom-up) modelling and atmospheric inversion (top-down) modelling. Thefirst part of t
Denna kunskapssammanställning beskriver hur hälsoskadlig värme kan uppstå inomhus, hur den kan identifieras och vilka åtgärder som kan vidtas med fokus på fastighetsägarens ansvar. Sammanställningen är begränsad till befintliga byggnader i Sverige och inkluderar skolor, äldreboenden, lägenheter, förskolor och kontor som är icke-industriella (utan industriella processer som producerar värme).

The review is limited to existing buildings in Sweden and includes schools, retirement homes, apartments, preschools, and non-industrial offices (those without industrial processes that produce heat). The expected climate
IGF-1 is an essential regulator of fetal growth and brain development. Preterm birth in the human is followed by a rapid decrease in serum levels of IGF-1 and decreased levels of IGF-1 have been associated with development of severemorbidity. A recent clinical trial indicated that supplementation with IGF-1 prevented development of severe intraventricular hemorrhage (IVH) in extremely preterm infa
As interest in the processes of integration of immigrants and ethnic minorities grows among European scholars, the role of multiple actors in shaping civic and political participation by people of migrant background needs to be further examined. Building on the literature on migration, this study addresses the following research question: What accounts for differences in forms of civic and politic
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
Carbohydrates are involved in many cellular processes, and most biomolecules are glycosylated.

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
In everyday life, we bind visual samples of the world into a coherent episodic memory via eye movements. Previous eye tracking research revealed that visual scrutiny, gaze transitions between event elements, and refixations during encoding predict successful memory formation. However, little is known about the neural mechanisms of these processes. Here, we combine EEG and eye tracking to investiga
