Rubber covered cylinders in rolling contact are studied in two cases; rolling over a flat surface and rolling over a groove. In the first case, two different finite element procedures are compared for the purpose of investigating if computational savings can be made when taking amplitude dependent effects into account by using a modified viscoelastic steady state rolling procedure. This procedure
Multimorbidity, according to the World Health Organization, exists when there are two or more chronic conditions in one patient. This definition seems inaccurate for the holistic approach to Family Medicine (FM) and long-term care. To avoid this pitfall the European General Practitioners Research Network (EGPRN) designed a comprehensive definition of multimorbidity using a systematic literature re
Popular Abstract in Swedish Cancer är den vanligaste dödsorsaken bland barn mellan 1–14 år i Sverige. Neuroblastom, som nästan uteslutande drabbar barn, är en aggressiv cancersjukdom som har sitt ursprung i det sympatiska (icke-viljestyrda) nervsystemet. I frisk vävnad råder strikt balans mellan celldelning och celldöd, medan cancerceller kännetecknas av en ohämmad celldelning och minskad celldödNeuroblastoma is a childhood tumor of the developing sympathetic nervous system (SNS) and is the most commonly diagnosed form of cancer in children before one year of age. Although survival curves have improved for these patients during the past decades, the conventional regimen of neuroblastoma treatment has clearly reached a plateau of efficiency with regard to increasing the survival rates of h
This study (N=37 with high, medium, and low hyp-notizables) evaluated depth reports and EEG activity during both voluntary and hypnotically induced left-arm lifting with sLORETA functional neuroimaging. The hypnotic condition was associated with higher activity in fast EEG frequencies in anterior regions and slow EEG frequencies in central-parietal regions, all left-sided. The voluntary condition
The purpose of this study is to describe and analyse changes in the pledge element of the ordination in the Church of Sweden. The transition in 1893 from a clerical oath to an affirmation will be particularly in focus and its causes and effects identified. My intention is thus to contribute to the history of the Swedish clerical oath, describing its complexity and multifarious range of meaning. In
To investigate the association between pre- and postoperative alcohol consumption and risk for early breast cancer events, since the association between alcohol consumption and prognosis in breast cancer patients is unclear.
In this work, we consider the problem of high-resolution estimation of the parameters detailing a two-dimensional (2-D) signal consisting of an unknown number of exponentially decaying sinusoidal components. Interpreting the estimation problem as a block (or group) sparse representation problem allows the decoupling of the 2-D data structure into a sum of outer-products of 1-D damped sinusoidal si
With more than 130,000 organizations worldwide certified according to ISO requirements, business people, regulatory authorities and other stakeholders have reason to wonder whether the purpose of ISO 14001, which is to help improve environmental performance, is being fulfilled. There is a growing body of literature attempting to answer this question. The results, however, are inconclusive. This m
In order to examine contemporary Russian cinema, this thesis has two points of departure: firstly the Petersburg myth, which is here defined as reversible or ambiguous since it includes both an eschatological and a cosmogonic aspect; and secondly, the Petersburg literary text as defined in works by Vladimir Toporov. During the twentieth century, the vitality and actuality of the Petersburg myth wa
Sorption of 75 active pharmaceutical ingredients (APIs) to three different types of sludge (primary sludge, secondary sludge with short and long sludge age respectively) were investigated. To obtain the sorption isotherms batch studies with the APIs mixture were performed in four nominal concentrations to water containing 1 g of sludge. The range of APIs concentrations was between ng L-1 to mu g L
High-energy proton- and deuteron-nucleus collisions provide an excellent tool for studying a wide array of physics effects, including modifications of parton distribution functions in nuclei, gluon saturation, and color neutralization and hadronization in a nuclear environment, among others. All of these effects are expected to have a significant dependence on the size of the nuclear target and th
Sex differences in occupational biomechanical exposures may be part of the explanation why musculoskeletal complaints and disorders tend to be more common among women than among men. We aimed to determine possible sex differences in task distribution and task-specific postures and movements of the upper extremities among Danish house painters, and to establish sex-specific task exposure matrices.
Popular Abstract in Swedish Många cancerceller har ovanligt höga nivåer av proteinet DEK och i vissa fall av leukemi har man hittat en genetisk förändring som leder till en variant kallad DEK-NUP214. Man tror därför att DEK kan vara en av faktorerna som bidrar till att vanliga celler omvandlas till cancerceller. En sådan roll har visats i experimentella modeller där man även sett att cancerceller The DEK gene is upregulated in a growing number of cancers and translocated to form the DEK-NUP214 fusion gene in a subset of acute myeloid leukemia. In this thesis, we studied the cellular and molecular functions of the DEK and DEK-NUP214 proteins. We found that the expression of DEK is increased by the leukemia-associated fusion protein NUP98-HOXA9, suggesting that DEK may be a downstream mediat
We present a noninvasive optical method to determine the local strain in individual semiconductor nanowires. InP nanowires were intentionally bent with an atomic force microscope and variations in the optical phonon frequency along the wires were mapped using Raman spectroscopy. Sections of the nanowires with a high curvature showed significantly broadened phonon lines. These observations together
Fucoxanthin-chlorophyll protein (FCP) is the key molecular complex performing the light-harvesting function in diatoms, which, being a major group of algae, are responsible for up to one quarter of the total primary production on Earth. These photosynthetic organisms contain an unusually large amount of the carotenoid fucoxanthin, which absorbs the light in the blue-green spectral region and trans
A study is presented about the effects of three glazing colour types (blue, neutral, bronze) on daylight quality, arousal and switch-on patterns for electric lights. This study was carried out using a scale model (1:4) of an office room, where subjective evaluations of the luminous conditions were performed by 36 participants (mean age 23.8 years) with their upper bodies immersed in the model. The
Osteoblastoma is a bone forming tumor with histological features highly similar to osteoid osteoma; the discrimination between the tumor types is based on size and growth pattern. The vast majority of osteoblastomas are benign but there is a group of so-called aggressive osteoblastomas that can be diagnostically challenging at the histopathological level. The genetic aberrations required for osteo
