People that have driven a car with a trailer at high speed know that the trailer can begin to oscillate. This oscillation is known as snake behavior. How much the car and trailer starts to oscillate depends on how the trailer is loaded. An empty trailer does not tend to oscillate, while a heavy loaded trailer, with the load centered over the trailer axle, oscillates more easily. For a normal perso
The migration politics in Sweden have changed drastically within the past years as it has introduced stricter asylum policies and higher securitisation of borders. As a result, an increased number of people are forced to live as undocumented migrants, meaning without a legal permit to stay in the country. This thesis aims to contribute to the analysis of this development by investigating the role
Activation of AMP-activated protein kinase (AMPK) by exercise and metformin is beneficial for the treatment of type 2 diabetes. We recently found that, in cultured cells, the LKB1 tumor suppressor protein kinase activates AMPK in response to the metformin analog phenformin and the AMP mimetic drug 5-aminoimidazole-4-carboxamide-1-beta-D-ribofuranoside (AICAR). We have also reported that LKB1 activ
Antisera produced against peptides deduced from potato nda1 and ndb1, homologues of yeast genes for mitochondrial rotenone-insensitive NADH dehydrogenases, recognise respective proteins upon expression in Escherichiacoli. In western blots of potato (Solanum tuberosum L.) mitochondrial proteins, the NDB and NDA antibodies specifically detect polypeptides of 61 and 48 kDa, respectively. The proteins
Accessibility in public outdoor environments for those with reduced functional capacity has been gaining interest on both the international and national levels. The study investigates how accessibility issues are currently treated in Swedish municipalities in order to examine how older peoples’ accessibility needs are met in daily practice. A postal questionnaire was sent to all municipalities in
In the past decade, the literature on transitions toward sustainable socio-technical systems has made a considerable contribution in understanding the complex and multi-dimensional shifts considered necessary to adapt societies and economies to sustainable modes of production and consumption. However, transition analyses have often neglected where transitions take place, and the spatial configurat
Invaders generally show better individual performance than non-invaders and, therefore, vital rates (survival, growth, fecundity) could potentially be used to predict species invasiveness outside their native range. Comparative studies have usually correlated vital rates with the invasiveness status of species, while few studies have investigated them in relation to population growth rate. Here, I
BACKGROUND: Mechanisms regulating the ABO gene are unclear, especially in the hematopoietic compartment. The number of 43-bp repeats in the CBF/NF-Y-binding enhancer region is considered to have a major influence on transcription. STUDY DESIGN AND METHODS: Transcript levels in peripheral blood and in erythropoietic culture of CD34+ cells from marrow donors were measured with TaqMan assays. The 5'-
Where does linguistic structure come from? Recent gesture elicitation studies have indicated that constituent order (corresponding to for instance subject - verb - object, or SVO in English) may be heavily influenced by human cognitive biases constraining gesture production and transmission. Here we explore the alternative hypothesis that syntactic patterns are motivated by multiple environmental
Popular Abstract in Swedish Intresset för evidens-baserad vård växer snabbt men trots att nya forskningsresultat produceras och publiceras löpande, tar det lång tid innan de får genomslag i den vård som erbjuds patienter och brukare. Det finns beräkningar som talar för att det tar mellan åtta och trettio år innan tillgängliga forskningsresultat har blivit implementerade och börjat användas rutinmäThe aim of this thesis was to investigate and synthesise the knowledge base concerning leadership and its influence on the implementation of evidence-based practice. A further aim was to investigate attitudes and beliefs among politicians, healthcare managers and mental healthcare professionals about the Swedish national guidelines for schizophrenia or schizophrenia-like conditions. Data was colle
Plumage ornamentation often signals the quality of males and, therefore, female birds may choose elaborately ornamented mates to increase their fitness. Such mate choice may confer both direct and indirect benefits to the offspring. Males with elaborate ornaments may provide good genes, which can result in better nestling growth, survival or resistance against parasitic infections. However, these
Hydrophobic hydration, the perturbation of the aqueous solvent near an apolar solute or interface, is a fundamental ingredient in many chemical and biological processes. Both bulk water and aqueous solutions of apolar solutes behave anomalously at low temperatures for reasons that are not fully understood. Here, we use 2H NMR relaxation to characterize the rotational dynamics in hydrophobic hydrat
During recent decades women have made considerable advances in education and the labor market, even in fast-track professions such as law, medicine, and academia. While women have entered high-status professions, the career paths of some jobs have changed little and are still inflexible, which implies that professional gains may be offset by familial losses. We investigate continued childbearing,
Bioassay experiments were performed two times (with 2 years in between) in order to investigate if nitrogen (N, ammonium), phosphorus (P, phosphate) and carbon (C, glucose) additions would stimulate the growth of bacteria and phytoplankton differently in three different tropical aquatic environments. The water and their indigenous microbial communities were taken from a freshwater coastal lake (Ca
Background: Research suggests that the growing prevalence of obesity may be related to the influence of the health behaviours of peers. We look at clustering of exercise and eating behaviours amongst a previously unstudied group, young adults in Sweden. Previous research has mainly been conducted in the United States and Britain, countries that have relatively high rates of obesity. Methods: Using
BACKGROUND: Despite their pivotal roles in colorectal carcinogenesis, the interrelationship and prognostic significance of beta-catenin alterations and microsatellite instability (MSI) in colorectal cancer (CRC) needs to be further clarified. In this paper, we studied the associations between beta-catenin overexpression and MSI status with survival from CRC, and with expression of p21, p27, cyclin
The dilution effect of N-2/CO2 on the laminar burning velocity of H-2-CO-O-2 mixtures was investigated. The dilution fraction of N-2 and CO2 in the unburned mixtures varied from 0% to 70% and 0%-50%, respectively, and H-2 content in H-2-CO fuels altered from 5% to 100%. All the studies were carried out at standard laboratory conditions (1 atm, 298 K) with equivalence ratio changing from 0.6 to 2.0
Type 2 diabetes (T2D) and metabolic syndrome (MetS) are major health problems associated with cardiovascular disease. Both diseases are influenced by a combination of genetic and environmental factors. The aim of this thesis was to identify genetic risk factors for T2D, particularly T2D associated with obesity, and for MetS. To achieve this goal, we 1) followed-up a region linked to obese T2D in a
Context. It is still debated whether or not the Galactic chemical evolution of sulphur in the halo follows the flat trend with [Fe/H] that is ascribed to the result of explosive nucleosynthesis in type II SNe. It has been suggested that the disagreement between different investigations of sulphur abundances in halo stars might be owing to problems with the diagnostics used, that a new production s
Abstract in UndeterminedAbstractThe aim of this study is to investigate the structural licensing and the semantics of the dative-DP in ditransitive constructions in German from a cognitive and construction grammar perspective.While the indirect object in constructions with prototypical ditransitive verbs is said to be a lexically selected argument of the verb, the indirect object in beneficiary di
