Cities face a host of challenges including urbanisation and climate change and must quickly adapt and integrate sustainability solutions to deal with these challenges. One platform seen as a mechanism to support innovation for sustainability in cities is the concept of the living lab. A living lab is a user-centred, open innovation ecosystem that seeks to engage academia, industry and municipaliti

New legislation involving emissions from internal combustion engines are pushing the manu-facturers to develop new technology faster than ever before with the amount of greenhouse gases. To meet the standards new concepts need to be developed with lower fuel consumption and emissions. This thesis covers the implementation of a couple of methods to achieve this. These concepts are DEP with fully va

Den här studien undersökte effekter av en stresshanteringsintervention, som genomfördes med åtta elever på en svensk gymnasieskola under hösten 2015. Hypoteserna inför projektet var att interventionen som varade under åtta veckor skulle ha en positiv effekt på användandet av adaptiva copingstrategier samt reducera upplevd stressnivå och öka självskattad hälsa. De utfallsmått som användes var PerceThis study examined the effects of a stress management intervention that was carried out with eight Swedish high school students (Swedish gymnasium) during the fall semester of 2015. The hypotheses were that the eight week intervention would have a positive impact on the usage of adaptive coping strategies, reduce perceived stress for the participants and increase self-estimated overall health. Th

The aim of this project was to determine the consequences of the large-scale introduction of wood-based biofuels in the road transport sector. Therefore a model has been developed to project the demand for wood in Sweden in the period from 2007 to 2050. The wood-using sectors that were taken into account are: the sawmill industry; the paper and pulp industry, which was split in three: integrated c

Horisonter med subfossila stubbar och rötter av tall (Pinus sylvestris) är vanliga i stratigra-fier från torvmarker i norra Europa. Dessa är tydliga indikationer på att det under holocen funnits perioder med tillräckligt gynnsamma förhållanden för tallar att växa på mossar. Tall kan endast växa på mossar när ytan är tillräckligt torr, och därför är rester av tallar på mossar goda indikationer på eHorizons rich in subfossil stumps and roots of Scots pine (Pinus sylvestris) are frequently found in stratigraphies of northern European peatlands, providing clear evidence of Holocene periods with favourable conditions for bog-pine growth. The pines could only grow when bog-surface wetness was sufficiently low, and the presence of their remains is therefore a good indicator of past climatic condi

The gallium abundance in HgMn stars has been reported to be different for analyses conducted from spectral lines in the optical versus those from the ultraviolet. We pursue this ultraviolet-optical discrepancy from a line-blending perspective by investigating the Hubble Space Telescope (HST) Space Telescope Imaging Spectrograph (STIS) spectrum of the sharp-lined HgMn binary star chi Lup. Its galli

Conversion of lignocellulosic material to monomeric sugars and finally ethanol must be performed at low cost, i.e, with limited consumption of chemicals, yeast and enzymes while still reaching high yields, if it is to compete with other fuel conversion processes. The objective of this study was thus to investigate ethanol production from steam-pretreated wheat straw by simultaneous saccharificatio

Previous studies suggested a link between the use of G-CSF and increased incidence of myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) after immunosuppressive therapy (IST) for severe aplastic anemia (SAA). This European survey included 840 patients who received a first-line IST with (43%) or without (57%) G-CSF. The incidences of MDS/AML in patients who did or did not receive G-CSF

Aim: To analyse morbidity and mortality in healthy newborn infants in relation to various routines of post-natal follow-up. Design: cross-sectional study. Setting: maternity care in Sweden. Population: healthy infants born at term between 1999 and 2002 (n = 197 898). Methods: Assessment of post-natal follow-up routines after uncomplicated childbirth in 48 hospitals and data collected from the Swed

Background: Voltage-dependent K+ channels (Kv) mediate repolarisation of beta-cell action potentials, and thereby abrogate insulin secretion. The role of the Kv1.1 K+ channel in this process is however unclear. We tested for presence of Kv1.1 in different species and tested for a functional role of Kv1.1 by assessing pancreatic islet function in BALB/cByJ (wild-type) and megencephaly (mceph/mceph)

Massive MIMO can greatly increase both spectral and transmit-energy efficiency. This is achieved by allowing the number of antennas and RF chains to grow very large. However, the challenges include high system complexity and hardware energy consumption. Here we investigate the possibilities to reduce the required number of RF chains, by performing antenna selection. While this approach is not a ve

The paper describes a novel method for calculating the residual gas fraction and the trapping efficiency in a 2 stroke engine. Assuming one dimensional compressible flow through the inlet and exhaust ports, the method estimates the instantaneous mass flowing in and out from the combustion chamber; later the residual gas fraction and trapping efficiency are estimated combining together the perfect

The pine sawfly Neodiprion sertifer (Geoffroy) uses the acetate or propionate of (2S,3S,7S)-3,7-dimethyl-2-pentadecanol (diprionol) as pheromone components, with the (2S,3R,7R)-isomer being antagonistic, synergistic, or inactive according to the population tested. In this study, we tested the attraction of males to the acetates of three analogs of diprionol, each missing one methyl group, viz. (2S

Introduction. The aim of this model study was to estimate and compare the risk of radiation-induced adverse late effects in pediatric patients with medulloblastoma (MB) treated with either three-dimensional conformal radiotherapy (3D CRT), inversely-optimized arc therapy (RapidArc ® (RA)) or spot-scanned intensity-modulated proton therapy (IMPT). The aim was also to find dose-volume toxicity param

The overall aim of thesis was to explore frail older people’s experiences of receiving healthcare and/or social services and to investigate healthcare consumption and costs in both men and women and in different age groups in the two years prior to the introduction of long-term municipal care. A second aim was to explore a preventive intervention in a pilot study using case managers to older peopl

Due to globalization, increasing amounts of water are traded across borders as virtual water embodied in traded products. The thesis traces global water trade patterns at different levels of income between 1990 and 2015 in order to test whether developed countries outsource their water-intensive production to less developed countries increasing global water use in the process. The research problem

With a far going protection of IP rights, the EU aims to protect the assets of companies which invested in innovative products. If the EU framework provides a far going mechanism of protection of IP rights, the complexity and the cost of this mechanism have been a barrier to the access of IP rights. In additional to these structural issues, the digital revolution introduced new challenges for the
