The incidence of hip fracture in Sweden is substantially lower in immigrants than in the population born in Sweden. Thus, the use of a FRAXA (R) model in immigrants overestimates the risk of fracture, and the use of country of origin-specific models may be more appropriate. Introduction Age-specific fracture and mortality rates vary between countries so that FRAX tools are country-specific. In the

SAMMANFATTNING För att förstå inverkan av olika putsbruk, utförande och härdning på deformationer hos armerad puts utsattes putsremsor för uttorkning och upp fuktning under kontrollerade förhållanden. Putsremsornas deformationer, d.v.s. den axiella deformationen samt deformationer vinkelräta mot putsremsans längdaxel, bestämdes under pågående upp fuktning och uttorkning. Provningarna utfördes med

We report on studies of the formamidinium lead triiodide (FAPbI3) perovskite film using time-resolved terahertz (THz) spectroscopy (TRTS) and flash photolysis to explore charge carriers generation, migration, and recombination. The TRTS results show that upon femtosecond excitation above the absorption edge, the initial high photoconductivity (∼75 cm(2) V(-1) s(-1)) remains constant at least up to

Discriminative touch relies on afferent information carried to the central nervous system by action potentials (spikes) in ensembles of primary afferents bundled in peripheral nerves. These sensory quanta are first processed by the cuneate nucleus before the afferent information is transmitted to brain networks serving specific perceptual and sensorimotor functions. Here we report data on the inte

The internal nanostructure of the diatoms Cyclotella meneghiniana, Seminavis robusta and Achnanthes subsessilis was investigated using small angle neutron scattering (SANS) to examine thin biosilica samples, consisting of isotropic (powder) from their isolated cell walls. The interpretation of SANS data was assisted by several other measurements. The N-2 adsorption, interpreted within the Branuer-

This thesis describes experiments aimed at developing a key component in applications such as quantum networks and long-distance quantum communication systems: quantum memories. Quantum memories for light using photon-echo and coherent rephrasing techniques have been developed. The work is carried out on rare-earth-ion-doped inorganic crystals. Several properties are associated with these crystals

There is a need for integrated care and smooth collaboration between care-providing organisations and professions to create a continuum of care for frail older people. However, collaboration between organisations and professions is often problematic. The aim of this study was to examine the process of implementing a new continuum of care model in a complex organisational context, and illuminate so

It is well known that patients with COPD have an increased risk of lower respiratory tract infections, but less is known about the association with other infections. The aim of this thesis was to explore epidemiological aspects of severe infections in COPD, using public registries in Sweden. In the first study, incidence rates of tuberculosis were compared in all individuals discharged with COPD,

Introduction: Treatment of acute lung injury (ALI) remains an unsolved problem in intensive care medicine. As simvastatin exerts protective effects in inflammatory diseases we explored its effects on development of ALI and due to the importance of neutrophils in ALI also on neutrophil effector functions. Methods: C57Bl/6 mice were exposed to aerosolized LPS (500 mg/ml) for 30 min. The count of alv

BACKGROUND: Cancer has consequences not only for the sick person but also for those who have a close relationship with that person. Greater knowledge about how family members manage the situation in the period immediately following the diagnosis means greater opportunity to provide the best possible support for the family. The purpose of this study was to explore management strategies that family

The influence of substrate orientation on the morphology of graphene growth on 6H-SiC(0 0 0 1) was investigated using low-energy electron and scanning tunneling microscopy (LEEM and STM). Large area monolayer graphene was successfully furnace-grown on these substrates. Larger terrace widths and smaller step heights were obtained on substrates with a smaller mis-orientation from on-axis (0.03°) tha

The ongoing globalisation and the rise of the knowledge economy creates new challenges for regional economic development. In order to cope with these challenges, regions need to strengthen the capacity of existing industries to innovate, but also transform their innovation systems and facilitate the emergence of new industries and development paths. The ability to transform and renew themselves, h

Popular Abstract in Swedish Benskörhet (osteoporos) är ett tillstånd som definieras av låg benmassa och ökar med stigande ålder. Osteoporos är idag en av de stora folksjukdomarna och man räknar med att en tiondel av alla män och en fjärdedel av alla kvinnor i Sverige drabbas. Tillståndet är i sig symptomfritt men ökar risken att råka ut för ett benbrott (fraktur) redan vid lättare fall. Frakturer The aim of this thesis was to evaluate risk factors for bone fragility and fractures in postmenopausal women in a long-term perspective. The study period spanned from the age of 48 to age 82 and is thus unique in its length. The studied sample was homogeneous and consisted of 390 north European women from a population-based cohort. At the start of the study, general health and lifestyle parameters

Background: Written prescriptions of physical activity have increased in popularity. Such schemes have mostly been evaluated in terms of efficacy in clinical trials. This study reports on a physical activity prescription referral scheme implemented in routine primary health care (PHC) in Sweden. The aim of this study was to evaluate patients' self-reported adherence to physical activity prescripti

T-STAR (testis-signal transduction and activation of RNA) is an RNA binding protein, containing an SH3-binding domain and thus potentially playing a role in integration of cell signaling and RNA metabolism. The specific function of T-STAR is unknown and its implication in cancer is poorly characterized. Expression of T-STAR has been reported in human testis, muscle and brain tissues, and is associ
