Context. Positions and proper motions of Gaia sources are expressed in a reference frame that ideally should be non-rotating relative to distant extragalactic objects, coincident with the International Celestial Reference System (ICRS), and consistent across all magnitudes. For sources fainter than 16th magnitude, this is achieved through Gaia's direct observations of quasars. At brighter magnitud
The high rate of disability pensioners is alarming in many industrial countries today. In Sweden the rate was 9.5% of the population aged 16-54 years in March 2005. Through new legislation, which came into force 2000, disability pensioners in Sweden are able to go back to work without jeopardising their benefit. This 'resting disability pension' was used by 0.2% of all disability pensioners in SweThe high rate of disability pensioners is alarming in many industrial countries today.

Estimating age distributions, or star formation histories, of stellar populations in the Milky Way is important in order to study the evolution of trends in elemental abundances and kinematics. We build on previous work to develop an algorithm for estimating the age-metallicity distribution which uses the full age-metallicity probability density functions (PDFs) of individual stars. No assumptions
Närsjukvård är ett centralt begrepp i ett förändringsarbete som för genomförs i nordöstra Skåne för att utveckla hälso- och sjukvårdsväsendet. Det ingår därmed som en av de centrala delarna av Region Skånes vision om hälso- och sjukvård: Skånsk livskraft – vård och hälsa. Syftet med denna rapport är att ge en bakgrund till begreppet (Del A) och att presentera en del preliminära rön beträffande hur
The dynamic response of blocks sitting on a half-space is considered. Buildings and other structures placed on or within the ground influence the transmission of seismic waves. Hence, the presence of a building will have an impact on the dynamic response of neighbouring buildings. Furthermore, obstacles such as concrete blocks lead to wave scattering that may be beneficial or unfavourable for the
Frequent language exposure and use are among the most important conditions for successful language learning whether in classrooms, during study abroad, or in other informal contexts. Research probing exposure and usage often relies on one-off self-report questionnaires in which participants estimate their typical level of language exposure over extended periods of time, often long after it occurre
I Att motverka skatteflykt undersöks de rättsliga avvägningar och följande gränsdragningsfrågor som åtföljer införandet av generella åtgärder mot skatteflykt. Studien motiveras av den harmonisering som under senare år skett inom unionsrätten, där antagandet av skatteflyktsdirektivets missbruksregel inneburit en betydande tillnärmning på företagsskatteområdet. Genom att studera och jämföra införlivThis doctoral disseration examines how the structure and function of the European Union’s (EU) newly introduced General Anti-Avoidance Rule (GAAR) affects the concept of tax avoidance in its member states. Through a comparative study of the Swedish and Danish approach to combating corporate tax avoidance, the dissertation focuses on both the pre-existing provisions against tax avoidance and the ru
Exposure to air pollution is associated with adverse health effects in humans, with special concern for exposure to fine particulate matter (PM2.5). The physicochemical properties of aerosols impact the health effects. Considering that we spend approximately 90% of our time indoors, it is important to gain increased understanding of indoor aerosol concentrations and properties. The overall aim of
The purpose of this study was to qualitatively evaluate recently introduced Model-based iterative reconstruction method (IMR) and routinely used iterative reconstruction algorithm iDose4 to investigate future dose reduction possibilities for abdominal CT exams. The study contained data from 34 patients who underwent abdominal CT in SkåneUniversityHospital Lund, Sweden. A low-dose scan (CTDIvol3.4
AIMS: Detecting changes in ventricular function after orthotopic heart transplantation (OHT) using transthoracic echocardiography (TTE) is important but interpretation of findings is complicated by lack of data on early graft adaptation. We sought to evaluate echocardiographic measures of ventricular size and function the first year following OHT including speckle tracking derived strain. We also
The ability to control the shape, distribution and composition of non-metallic inclusions has had an important impact on many aspects of steel making. One such impact is on the machinability. Ca-treatments have shown to be able to reduce the abrasiveness of oxide inclusions, improve chip-breaking and lead to formation of deposits that reduce tool wear. However, machining Ca-treated steels with Al2
The primary tool material when machining Ti6Al4V titanium alloy is uncoated straight cemented carbide. This study examines the performance of these materials during high-speed finish turning, and uses the advanced microscopy methods of SEM, (S)TEM, XEDS, and SAED to explore the fundamental tool wear mechanisms. The wear modes include a combination of flank wear and rake cratering. Four individual
