The Swedish transport administration (Trafikverket) uses turnkey contracts as a tool in their work with the assignment from the Swedish government to increase innovation and productivity in the construction sector which railway is included in. Qualitative interviews of the three different actors: clients (Trafikverket), constructors and consults have been made for the study. This is to get a pictu
Title: Next generation rear axle assembly - A case study at Scania Authors: Richard Andrae & William Bergmark Background: Following the development of industry 4.0, new production technologies enabling more efficient assembly processes constantly evolve. Scania is a leading manufacturer of trucks in Sweden, offering a wide product portfolio and the possibility for their customers to customize
The focus of this thesis is energy justice and sustainability science, and the argument is based on a case study of the Inga dams. Substantial further development of hydropower is planned at the Inga dams, located on the Congo River in the Democratic Republic of Congo. While the project will add macro-economic benefits through the additional power, benefits are limited for people living nearby, a
Nutrient uptake by forest trees is dependent on ectomycorrhizal (EM) mycelia that grow out into the soil from the mycorrhizal root tips. We estimated the production of EM mycelia in root free samples of pure spruce and mixed spruce-oak stands in southern Sweden as mycelia grown into sand-filled mesh bags placed at three different soil depths (0-10, 10-20 and 20-30 cm). The mesh bags were collected
Popular Abstract in Swedish I denna avhandling studeras new age utifrån problemområdena hälsa, kroppslighet och genus. Genom intervjuer med andliga sökare inom new age ges en bild av de trosföreställningar och attityder som kännetecknar rörelsen. Också sökarnas olika vägar till new age och relationer till andra religioner analyseras. I det senmoderna samhället är hälsa ett eftersträvansvärt livsväIn this thesis New Age is studied from a sociological perspective, with a focus on health, body, and gender. One purpose is to examine how people within New Age view and relate to these problem areas. A parallel purpose is to find explanations to why women predominantly take an interest in New Age, and to discover how these explanations are related to the view on health, body and gender. The subje
The effects of authentic nitric oxide (NO, 10(-6) M) and NO-donors such as sodium nitroprusside (SNP, 10(-5) M) and glyceryl trinitrate (GTN, 10(-4) M) on contractile force and free intracellular calcium level ([Ca2+],) were studied on precontracted with high potassium chloride (KCI, 70 mM) isolated rings of rat tail artery. The sensitivity of contractile myofilaments to Ca2+ was measured using ch
Rising temperatures can influence ecosystem processes both directly and indirectly, through effects on plant species and communities. An improved understanding of direct versus indirect effects of warming on ecosystem processes is needed for robust predictions of the impacts of climate change on terrestrial ecosystem carbon (C) dynamics. To explore potential direct and indirect effects of warming
The present status and development of strong-field nano-optics, an emerging field of nonlinear optics, is discussed. A nonperturbative regime of light-matter interactions is reached when the amplitude of the external electromagnetic fields that are driving a material approach or exceed the field strengths that bind the electrons inside the medium. In this strong-field regime, light-matter interact
Study objectives: Narcolepsy type 1 (NT1) is a chronic sleep disorder characterized by loss of hypocretin-producing neurons. Increased NT1 incidence was observed in Sweden following mass-vaccination with Pandemrix®. Genetic association to HLA DQB1*06:02 implies an autoimmune origin, but target autoantigen remains unknown. Candidate autoantigens for NT1 have previously been identified in solid-phas
ObjectivesThe formation of episodic memories is critically determined by how we visually sample the world over time via sequences of eye movements. Nonetheless, in the neuroscience of human memory, memory encoding has almost exclusively been studied in experimental paradigms where the study material is presented in a single fixed location on the screen, and where eye movements are treated as artif
Background: The St Gallen surrogate definition of the intrinsic subtypes of breast cancer consist of five subgroups based on estrogen receptor (ER), progesterone receptor (PgR), human epidermal growth factor receptor type 2 (HER2), and Ki-67. PgR and Ki-67 are used for discriminating between the ‘Luminal A-like’ and ‘Luminal B-like (HER2-negative)’ subtypes. Histological grade (G) has prognostic v
STUDY QUESTION: Do serum levels of anti-Müllerian hormone (AMH) change in women of reproductive age following dietary and surgery-induced weight loss?SUMMARY ANSWER: AMH levels increased after very low-calorie diet (VLCD) before surgery and decreased at 6 and 12 months after Roux-en-Y gastric bypass (RYGB), beyond expected normal age-related decline.WHAT IS KNOWN ALREADY: Obesity has negative effe
The purpose of this study was to develop a method to simulate breathing motion induced interplay effects for volumetric modulated arc therapy (VMAT), to verify the proposed method with measurements, and to use the method to investigate how interplay effects vary with different patient- and machine specific parameters. VMAT treatment plans were created on a virtual phantom in a treatment planning s
Popular Abstract in English Nowadays road, air and sea transport activities around the world are almost completely dependent on finite and polluting oil fuels. Biofuels are fuels produced from biomass which can be used to substitute gasoline and diesel in cars, busses and (soon) planes. Where oil was created millions of years ago and is soon reaching its limit, biofuels are renewable fuels which cThe dependency of transport on oil fuels is responsible for risks of energy supply security, and local, regional and global environmental problems, including the emission of greenhouse gases affecting the Earth’s climate system. Biofuels attracted considerable attention in recent years as a solution to these problems. However, the deployment of biofuel technologies poses as many opportunities to b
Over the last decades, the impact of human activities on the global nitrogen (N) cycle has drastically increased. Consequently, benthic N cycling has mainly been studied in anthropogenically impacted estuaries and coasts, while in oligotrophic systems its understanding is still scarce. Here we report on benthic solute fluxes and on rates of denitrification, anammox, and dissimilatory nitrate reduc
Many economic models contain the single variable 'money'. Money does not exist in the form of a single physical unit and it is common to construct monetary aggregates using the method of simple summations. Monetary aggregation theory lends little or no support to the method of simply summing various monetary asset components up to arbitrary levels of aggregation. In monetary aggregation theory, mo
The individual of a species is the basic unit which responds to climate and UV-B changes, and it responds over a wide range of time scales. The diversity of animal, plant and microbial species appears to be low in the Arctic, and decreases from the boreal forests to the polar deserts of the extreme North but primitive species are particularly abundant. This latitudinal decline is associated with a
Popular Abstract in Swedish Hur kommer det sig att liknande reformprogram återfinns i olika länder? Varför väljs vissa idéer framför andra? Avhandlingen syftar till att öka förståelsen av så kallad policydiffusion, spridning av olika typer av policy, och den dynamik som omgärdar spridningen. Detta görs genom att undersöka hur externa, eller utländska, idéer integreras och översätts i en ny omgivniSimilar policies may be found in different countries. This, in turn, is an indication that policies travel. But why are certain policies imitated while others are not? The author seeks to further our understanding of policy diffusion and its dynamics by investigating how foreign ideas are integrated and translated into new contexts, and how these imported ideas influence national policymaking and
Wnt5a is a non-canonical secreted glycoprotein of the Wnt family that plays important roles in organ development and tissue orientation. Previous studies have reported that Wnt5a was upregulated at both mRNA and protein levels in prostate cancer, but information regarding its role in predicting clinical outcome in patients after radical prostatectomy is limited. The aim of the present thesis is to
Herbivores are known to decrease plant species diversity in ecosystems with low productivity. Limestone pavements are low-productive habitats harboring specialized communities of cyanobacteria, and endo- and epilithic lichens exposed to extreme temperature and humidity fluctuations. Pavements of the Great Alvar (O¨ land, Sweden) are covered by free-living cyanobacteria giving the rock surface a da
