Climatic conditions during the winter in countries situated in the north can be considered severe. This is especially true for hydraulic structures, such as hydro power structures, dams, harbours, canals and some bridge foundations. Freezing of concrete in contact with unfrozen fresh water may have a considerable impact on the deterioration process of concrete. This paper presents results obtained
The PYTHIA program is a standard tool for the generation of events in high-energy collisions, comprising a coherent set of physics models for the evolution from a few-body hard process to a complex multiparticle final state. It contains a library of hard processes, models for initial- and final-state parton showers, matching and merging methods between hard processes and parton showers, multiparto
This paper presents a low voltage continuous-time delta-sigma modulator (DSM) intended for the receiver of an ultra-low-power radio. The DSM features a 2nd-order loop filter implemented with a single operational amplifier to reduce the power consumption. Furthermore, a 4-bit quantizer is used to achieve high resolution while keeping the sampling frequency low. The quantizer is realized using the s
This paper presents a 3rd-order, 3-bit continuous-time (CT) \Updelta\Upsigma Δ Σ modulator for an LTE radio receiver. A return-to-zero (RZ) pulse, centered in the sampling period by a quadrature clock, is used in the innermost DAC to reduce the sensitivity to loop-delay variations in the modulator, and omit implementing the additional loop delay compensation usually needed in CT modulators. The pe
Popular Abstract in English Atherosclerosis is a disease of medium and large sized vessels of our bodies that is mainly characterized by the deposition of lipids in the vessel walls. Increased lipid levels in the blood of an individual, because of lifestyle habits but also because of genetics, can lead to the formation of an “atherosclerotic plaque”. Thus, although lipids are important for the norAtherosclerosis is a chronic inflammatory disease of medium and large vessels of the body which is mainly characterized by the formation of lipid rich plaques within the arterial tissue. It is the most common cause of cardiovascular disease leading to clinical manifestations of coronary artery and cerebrovascular disease. Immune responses targeting modified low density lipoprotein (LDL) play an im
Popular Abstract in Swedish See attachment in related materialThe combustion engine is today the dominant technology for transportation of goods and people world-wide. Concerns for global warming, toxic exhaust emissions, as well as cost and availability of fuel have in recent years created incentives for technological evolution of combustion engines. More sophisticated engine instrumentation with additional degrees of freedom has been added to the engine de
Playing digital games is now a common everyday practice in many homes. This paper deals with the constitution of such practices by taking a closer look at the material objects essential to play and their role in the “design of everyday life” (Shove et al 2007). It uses ethnographic method and anthropological practice theory to attend to the domestic spaces of leisure and play, the home environment
This text deals with a problem concerning processes of the productive power of knowledge. We draw on so called poststructural theories challenging the classical image of thought – as hinged upon a representational logic identifying entities in a rigid sense – when formulating a problem concerning the gap between knowledge and the object of knowledge. More specifically we are looking at this proble
Today, 14 years have gone since the whole world turned their backs on Rwanda, the small country in East Africa, during a time when its population needed us the most. These were the same nations that already after the Second World War had made a promise about ''Never Again'', then meaning that they would never again allow another attempt to exterminate an entire ethnic group. It was
Social capital is a concept that has gained widespread use and recognition in many academic disciplines. This interest stems from an idea that the social capital produced in the organisations and associations of civil society can be beneficial in the creation and furthering of democratic processes and economic development among many other things. Using normative methods of consequentiality I will
Metal fuels can be promising candidates as alternative energy sources and renewable energy carriers within the metal-fuel cycle. They feature high energy density, low environmental impact, and broad production and application. One challenge in metal particle combustion lies in its multi-physics complexity compared to traditional hydrocarbon fuels. This thesis intends to investigate the combustion
The building sector, as a major consumer of energy and resources, has been slow to adopt sustainability and digitalization compared to other sectors. This dissertation investigates how digital tools, particularly computational design (CD), can support the reuse of building parts within a circular economy framework, through design for disassembly and reuse-centred design (RCD) strategies. The resea
We carry out bipolar Monte Carlo (MC) simulations of electron and hole transport in a multi-quantum well light-emitting diode with an electron-blocking layer. The MC simulation accounts for the most important interband recombination and intraband scattering processes and solves self-consistently for the non-quasiequilibrium transport. The fully bipolar MC simulator results in better convergence th
In pristine Sphagnum-dominated peatlands, (di)nitrogen (N2) fixing (diazotrophic) microbial communities associated with Sphagnum mosses contribute substantially to the total nitrogen input, increasing carbon sequestration. The rates of symbiotic nitrogen fixation reported for Sphagnum peatlands, are, however, highly variable, and experimental work on regulating factors that can mechanistically exp
In the contemporary dual crisis, economic crisis policies cannot be dealt with in isolation from the rampant and acute ecological crisis – and vice versa. In this article, we challenge the hegemonic positions in purported attempts to solve the crises so far: in the economic realm, the Keynesian episode of 2008–2009 as well as austerity policies, and with regard to the ecological crisis, ecologicalIn the contemporary dual crisis, economic crisis policies cannot be dealt with in isolation from the rampant and acute ecological crisis – and vice versa.

Understanding human development among the oldest old is a sequential building process taking into account building-block data, theories, and models from childhood, adulthood, and old age toward a new territory of oldest-old survivors who have lived way beyond the average life-span. A central question is whether the oldest-old survivors have developed specific survival techniques and/or protective
When on September 15, 2008 the financial conglomerate Lehman Brothers files for bankruptcy – and with that ‘officially’ sparks off the international financial crisis – few would have anticipated the invasive effect this crisis would come to have on the professional and personal lives of many across the world. Today, this implosion remains a mere ‘blip’ in the universe of events that ensued. On clo
The focus of this paper is on investigating the influence of skewing on the torque production of an Interior Permanent Magnet Synchronous Machine (IPMSM). The machine is designed as a traction machine according to the requirements of a parallel hybrid electric commercial heavy vehicle. In order to meet the requirements, the machine is designed with a speed higher than that of the conventional powe
An improvement in our process-based understanding of carbon (C) exchange in the Arctic and its climate sensitivity is critically needed for understanding the response of tundra ecosystems to a changing climate. In this context, we analysed the net ecosystem exchange (NEE) of CO2 in West Greenland tundra (64°N) across eight snow-free periods in 8 consecutive years, and characterized the key process
Several studies demonstrate the value of residents’ voices in the place branding process, however, relatively little is known about how residents experience participating in place branding campaigns and the consequences for place identity. This chapter explores the question of whether participatory branding initiatives could potentially lead to more inclusionary representational spaces in the city
