This thesis summarizes the experimental work in which an ultrafastX-ray laser plasma source was combined with variousscalable direct detection schemes to test a novel approach forlab-based time-resolved X-ray absorption spectroscopy. A laserplasma source based on a water jet target was built and commissioned.X-ray and electron emissions of this source were characterizedwith various direct detectio

BACKGROUND: A possible role for prostate cancer in Lynch syndrome has been debated based on observations of mismatch-repair defective tumors and reports of an increased risk of prostate cancer in mutation carriers. Potential inclusion of prostate cancer in the Lynch syndrome tumor spectrum is relevant for family classification, risk estimates and surveillance recommendations in mutation carriers.M

We demonstrate that an undamped few-body precursor of the Higgs mode can be investigated in a harmonically trapped Fermi gas. Using exact diagonalization, the lowest monopole mode frequency is shown to depend nonmonotonically on the interaction strength, having a minimum in a crossover region. The minimum deepens with increasing particle number, reflecting that the mode is the few-body analogue of

Background: Numerous scientific organisations have developed evidence-based recommendations aiming to optimise the management of osteoarthritis (OA). Uptake, however, has been suboptimal. The purpose of this exercise was to harmonize the recent recommendations and develop a user-friendly treatment algorithm to facilitate translation of evidence into practice. Methods: We updated a previous systema

Background: Recent evidence shows that arthroscopic partial meniscectomy (APM) offers no benefit over conservative treatment of patients with a degenerative meniscus tear. However, patients who report mechanical symptoms (sensations of knee catching or locking) may benefit from APM. Objective: To assess whether APM improves mechanical symptoms better than sham surgery. Design: Randomized, patient-

BACKGROUND: The aim was to assess time trend of mortality with musculoskeletal disorders (MSD) as underlying cause of death in Sweden from 1997 to 2013.METHODS: We obtained data on MSD as underlying cause of death across age and sex groups from the National Board of Health and Welfare's Cause of Death Register. Age-standardized mortality rates per million population for all MSD, its six major subg

Objectives: Study formal and informal care of community-living older people in the Swedish National study of Aging and Care (SNAC). Design: Cross-sectional, population based cohort. Setting: Three areas in Sweden: Municipality of Nordanstig, Stockholm and Skåne County. Participants: 3,338 persons ≥72 years. Measurements: Patterns and amounts of informal and formal care by cognition and area of res

We study the exciton dynamics in an optically excited nanocrystal quantum dot. Multiple exciton formation is more efficient in nanocrystal quantum dots compared to bulk semiconductors due to enhanced Coulomb interactions and the absence of conservation of momentum. The formation of multiple excitons is dependent on different excitation parameters and the dissipation. We study this process within a

Shift work has been proposed to promote cognitive disturbances in humans; however, conflicting evidence is also present. By using data from 7143 middle-aged and elderly humans (45-75 years) who participated in the Swedish EpiHealth cohort study, the present analysis sought to investigate whether self-reported shift work history would be associated with performance on the trail making test (TMT). T

We analyze theoretically a superlattice structure proposed by A. Andronov et al. [JETP Lett. 102, 207 (2015)] to give Terahertz gain for an operation point with positive differential conductivity. Here we confirm the existence of gain and show that an optimized structure displays gain above 20 cm-1 at low temperatures, so that lasing may be observable. Comparing a variety of simulations, this gain

Estimates of direct and indirect costs of psoriasis are limited. The aim of this study was to estimate: (i) costs in patients with psoriasis compared with controls; and (ii) impact on costs from initiating biologics. The study extracted data from Swedish administrative registers and compared 31,043 patients with 111,645 sex-, age- and residency-matched referents. Mean direct and indirect costs wer

The aim of this study was to describe hospitalised cancer patients' perceptions of individualised care in four European countries and compare these perceptions using the patients' socio-demographic characteristics and the Individualized Care Scale. The patients' socio-demographic characteristics used were: education, age, gender, type of hospital admission, previous hospitalisation and hospital le
