Hematopoiesis serves as a paradigm for how homeostasis is maintained within hierarchically organized cell populations. However, important questions remain as to the contribution of hematopoietic stem cells (HSCs) toward maintaining steady state hematopoiesis. A number of in vivo lineage labeling and propagation studies have given rise to contradictory interpretations, leaving key properties of ste

Molecular aggregates on plasmonic nanoparticles have emerged as attractive systems for the studies of polaritonic light-matter states, called plexcitons. Such systems are tunable, scalable, easy to synthesize, and offer sub-wavelength confinement, all while giving access to the ultrastrong light-matter coupling regime, promising a plethora of applications. However, the complexity of these material

This doctoral study aims to (i) investigate current song repertoire and singing practices in Swedish elementary school music education and (ii) to critically assess what factors may be seen to affect singing practices and repertoire choice. It looks to map out how much young students are singing in the general music classroom, what they sing, and how they sing, and to discuss possible implications

OBJECTIVE: Kawasaki disease (KD) is a vasculitis of unknown aetiology with a high risk of coronary aneurysms if untreated. Timely treatment with intravenous immunoglobulin decreases the risk for coronary artery aneurysms (CAA). In this study, we set out to elucidate the factors associated with the risk of developing CAA. METHODS: Records of all KD-diagnosed children in Skåne between 2004 and 2014

An organogel was prepared by chemically cross-linking a poly(styrene-block-4-vinylpyridine) diblock copolymer using dibromododecane in dimethylformamide. Analysis of the prominent structure peak in small-angle X-ray scattering along with the results of light scattering and rheological profile suggests the bridging of the spherical micelles to one another to form an interconnected network after gel

OBJECTIVES: To study baseline serum hepatocyte growth factor (s-HGF) as a predictor of spinal radiographic progression overall and by sex and to analyse factors correlated to changes in s-HGF in patients with AS. METHODS: At baseline and the 5-year follow-up, s-HGF was analysed with ELISA. Spinal radiographs were graded according to modified Stoke Ankylosing Spondylitis Spinal Score. Radiographic

High-quality biosecurity practices are critical to restarting international tourism. Effective market segmentation improves the communication and efficacy of health advice. Travel frequency is an important basis for health-related consumer segmentation, as it is closely related to risk of greater exposure to infectious diseases. Theoretically grounded studies of tourist biosecurity behavior and tr

Surface chemistry and nanotopography of dental implants can have a substantial impact on osseointegration. The aim of this investigation was to evaluate the effects of surface chemistry and nanotopography on the osseointegration of titanium‐zirconium (TiZr; Roxolid®) discs, using a biomechanical pull‐out model in rabbits. Two discs each were placed in both the right and left tibiae of 16 rabbits.

We study in detail the linear flow of particles on a graph with one vertex and k+1 infinite edges. This has a rich environment with many different emergent behaviours depending on the system parameters. The abrupt change in the behaviour of the system along a continuous change of the parameters manifests multiple phase transitions.We discuss the physical interpretation of the considered simple modWe study in detail the linear flow of particles on a graph with onevertex and k+1 infinite edges.

The housing environment is important for health and well-being among older people, and it is important to consider both physical and perceived aspects of housing. Psychometrically sound scales are necessary to assess perceived housing. This study evaluated the psychometric properties of two instruments that measure perceived aspects of housing among a younger cohort of older adults in Sweden. Meth

Radioresistance, the failure to achieve a desired outcome, is an obstacle in clinical radiotherapy. In this thesis we investigate factors affecting radioresistance and strategies to overcome it, both with established clinical approaches and by using novel pre-clinical discoveries. Study I & II concern the impact of tumour volume in patients with oropharyngeal cancer. In a large, pooled cohort

This letter proposes a two-port MIMO smartphone antenna for frequency bands below 1 GHz, which is robust to user effects. The design is achieved by first analyzing the characteristic modes of a chassis that includes the large screen. Two modes predicted to be less affected by the user than other commonly used modes are selected. The modal currents and near-fields of the two desired modes then guid

The rise in CDOM (coloured dissloved organic matter) is likely to be relatively more pronounced in remote northern regions. However, there is a lack of monitoring to confirm this. For this reason, there is a strong incentive to develop remote sensing-based methods to map CDOM in lakes across broader geographical scales and to include geograghic contex in such analysis. There is a lack of understan

The concept of “Sustainable water use” (SWU) aims to assure three pillars of sustainability related to the water sector: the social, environmental, and economical. Industrial development, especially in developing countries, requires an adequate response, as industrial activities are recognized as one of the major sources of water pollution, what leads to deterioration of environmental safety and w
