Popular Abstract in Swedish Hur gick det till när det svenska riket expanderade norrut och införlivade Hälsingland? Denna bok är uppställd som en generalhypotes över denna långt utdragna process, som tar sin utgångspunkt i den samhälleliga kollaps som är skönjbar under 500-talet. De inhemska maktstrukturer som gradvis byggdes upp efteråt kom under medeltidens inledande århundraden att få känna på In which way did the power structures of central Sweden expand into the territories north of the forest Ödmården during the Middle Ages? This text reads like a general hypothesis for this process, which attempts to incorporate all relevant elements in the Medieval landscape of power. The study area chosen is the province of Hälsingland. The chronological take-off is the 6th century AD, when settle

This thesis analyses web statistics belonging to a national B2C e-commerce in retail. The purpose of the thesis is to investigate abandoned carts amongst logged in customers with at least one product added in to their cart and at least one visit to the payment page. Since the response variable "cart" is binary and we are studying the probability of a cart being abandoned, the suitable me

An alternative energy and chemicals must be found to meet the future demand. A possible source of renewable energy is plant oil since it has a close chemical structure to fossil oil with less refining requirement. However, vegetable oil has not made a significant contribution to replace fossil oil as an energy source because of high demand of fossil oil. It is possible to substitute fossil-based c

The product price given when producing offshore is not the entire truth and more companies decide to move their offshore production nearshore (Stentoft et. al, 2016). To measure the actual cost of producing many more parameters than visible costs needs to be taken account for. There are advantages as well as risks with outsourcing and costs can increase with distance such as quality issues, freigh

In our society, digital cameras are used for a countless number of different purposes. There are many components going in to making such a complex product but one could argue that the camera sensor and lens make out the heart of a digital camera. Axis Communications AB, founded in 1984, is a Swedish company which pioneered and specialize in digital network cameras. In 1996 Axis delivered the first

This master’s thesis focuses on pedagogy and aspects of learning and remembering within guided museum tours for people with dementia. We explore in what way learning and remembering are focused on and triggered during those tours and with the help of which pedagogical means. Furthermore, we discuss what place these tours have within the museum as an institution. In order to examine our questions a

Background: Intravesical instillation of bacillus Calmette-Guérin (BCG) is an accepted strategy to prevent recurrence of non–muscle-invasive bladder cancer (NMIBC) but associated with significant toxicity. Objective: NIMBUS assessed whether a reduced number of standard-dose BCG instillations are noninferior to the standard number and dose in patients with high-grade NMIBC. Design, setting, and par

The research area of climate field reconstructions has developed strongly during the past 20 years, motivated by the need to understand the complex dynamics of the earth system in a changing climate. Climate field reconstructions aim to build a consistent gridded climate reconstruction of different variables, often from a range of climate proxies, using either statistical tools or a climate model

Deoxygenation, i.e. loss of oxygen from the oceans, often considerably influences the aquatic organisms and the wholeecosystem and changes biogeochemical cycles. It results in increasing bottom areas of hypoxia (<2 mg/l dissolved oxygen),which has been primarily attributed to global warming and increased eutrophication. It is vital to study the present-dayanthropogenically-induced environmental ch

Osteoarthritis (OA) is the most common form of arthritis and often causes pain and functional impairment. Despite its high burden on society, knowledge about the occurrence of OA and its associated mortality is sparse. The epidemiology of OA is difficult to determine due to the patients’ fluctuating symptoms and challenges in detecting and defining the radiographic disease. The specific aims of th

The characterization of naturally occurring mutations is one way to approach functionally significant domains of polypeptides. About 10 mutations have been reported in factor XIII (FXIII) A-subunit deficiency, but very little is known about the effects of the mutations on the expression or the structure of this enzyme. In this study, the recent crystallization of FXIII A-subunit and determination

Recent work on heritage and social media has highlighted how social media offer new possibilities for citizens to share memories, identities, local culture and heritage, and thus constitute a more participatory and democratic platform (Giaccardi 2012). Social media encourage and enable new forms of engagement and interpretations of the heritage through user-generated content, personal reflections,

Biogenic volatile organic compounds (BVOCs) play an important role in the chemistry of the troposphere, especially in the formation of tropospheric ozone (O3) and secondary organic aerosols (SOA). Ecosystems produce and emit a large number of BVOCs. It is estimated on a global scale that approximately 90% of annual BVOC emissions are from terrestrial sources. In this study, measurements of BVOCs w

Background Immunotherapy targeting the amyloid beta (A beta) peptide is a potential strategy to slow the progression of Alzheimer's disease. We aimed to assess the safety and tolerability of CAD106, a novel active A beta immunotherapy for patients with Alzheimer's disease, designed to induce N-terminal A beta-specific antibodies without an A beta-specific T-cell response. Methods We did a phase 1,

Background The leucine-rich repeat kinase 2 gene (LRRK2) harbours highly penetrant mutations that are linked to familial parkinsonism. However, the extent of its polymorphic variability in relation to risk of Parkinson's disease (PD) has not been assessed systematically. We therefore assessed the frequency of LRRK2 exonic variants in individuals with and without PD, to investigate the role of the

Popular Abstract in English Lions (Panthera leo) have become known to be synonymous with wild Africa since its extinction from most parts of its former range (Europe, Asia and Southern America). Few people realize that anthropogenic activities have caused habitat loss, fragmentation and reduction in size to the lions, forcing them to the brink of extinction. Whenever out in nature, most tourists tHigh growth rate in human populations, agricultural developments and industrialization have impinged negatively on the natural habitats of most large carnivores, causing fragmentation, isolation and consequently reduction in population size. Lions (Panthera leo) that once roamed most parts of Southern Europe, Asia, the Middle East, North America, northern part of South America and most parts of Af

Popular Abstract in Swedish Många fåglar flyttar regelbundet långa sträckor mellan sina häckningsplatser och vinterkvarter. På rastningsplatser längs flyttningsvägen stannar fåglarna upp och äter, för att lagra upp de energi-lager de behöver som bränsle när de flyger. Vissa flyttfåglar lägger på sig så mycket bränsle (energi), mestadels som fett, att de dubblar sin kroppsvikt. Det lagrade bränslet
