Eclipsing binaries are important benchmark objects to test and calibrate stellar structure and evolution models. This is especially true for binaries with a fully convective M-dwarf component for which direct measurements of these stars' masses and radii are difficult using other techniques. Within the potential of M-dwarfs to be exoplanet host stars, the accuracy of theoretical predictions of the

Uncertainty quantification (UQ) tasks, such as sensitivity analysis and parameter estimation, entail a huge computational complexity when dealing with input-output maps involving the solution of nonlinear differential problems, because of the need to query expensive numerical solvers repeatedly. Projection-based reduced order models (ROMs), such as the Galerkin-reduced basis (RB) method, have been

Context. With the aid of stellar abundance analysis, it is possible to study the galactic formation and evolution. Magnesium is an important element to trace the α-element evolution in our Galaxy. For chemical abundance analysis, such as magnesium abundance, accurate and complete atomic data are essential. Inaccurate atomic data lead to uncertain abundances and prevent discrimination between diffe

Background. Expression of the peptide hormones ghrelin and obestatin has previously been demonstrated in human mammary glands. However, the clinical implications of the expression of these peptides in breast cancer are unclear. The aim of this study was to investigate the potential clinical value of ghrelin and obestatin as breast cancer biomarkers. Methods. A tissue microarray containing breast c

Aims. In this paper we demonstrate how Stromgren uvby photometry can be efficiently used to: 1. identify red giant branch stars that are members in a dwarf spheroidal galaxy; 2. derive age-independent metallicities for the same stars and quantify the associated errors. Methods. Stromgren uvby photometry in a 11 x 22 arcmin field centered on the Draco dwarf spheroidal galaxy was obtained using the

Background: The clinical management of patients with coronary artery disease (CAD) often involves a complex assessment of the extent and severity of changes in left ventricular (LV) myocardial perfusion, function and viability. We aimed to explore the feasibility of integrative quantitative representation of LV perfusion, function and viability in adjacent polar plots. In order to assess the clini

Aims: The aim of this study was to find variables related to positive attitudes to physical education (PE) and strong sense of coherence (SOC) among adolescents. Methods: The study included three parts: seven physical tests; a questionnaire which included ways of living, attitudes to PE, and subjective health, the 13-question version of SOC; and information on every student's grades. The study gro

Background/aim: People with profound cognitive disabilities are not expected to learn powered mobility use. The Driving to Learn project focussed on what this population could achieve from practising in a joystick-operated powered wheelchair. By means of using grounded theory methodology an eight-phase process 'growing consciousness of joystick-use' was identified. In addition, a tool for assessme

Examensarbetet är utfört på och i samarbete med Imtech Ventilation i Malmö. Författarens avsikt har från början varit att skapa något som kan vara till stor nytta för företaget. Därför har examensarbetet utförts i nära samarbete med Imtech Ventilations medarbetare. Författaren har gjort en bakgrundsanalys av energikravs-läget i byggbranchen. Detta för att ta fram en validerad problemformulering ocThis master thesis is performed on and in cooperation with Imtech ventilation in Malmö. The author's intention was from the beginning to create something that can be of great benefit to the company. The master thesis has been carried out in close cooperation with the employees of Imtech Ventilation. The author has done a background analysis of the current excising energy regulations. This was

Kanada är väldigt rikt på energiresurser och fjärde största vattenkraftproducenten i världen. Provinsen Quebec står för omkring 52% av Kanadas totala vattenkraftsproduktion, och ener- gimarknaden Quebec domineras fullständigt av vattenkraft: 96% av elen genereras där av vattenkraft. I avreglerade vattenkraftdominerade energimarknader är det vanligt att det finns ett samband mellan vatteninflödet tCanada is plentiful in resources and the fourth largest producer of hydropower in the world. The province of Quebec stands for about 52% of Canada’s total hydropower production, and the Quebecois energy market is totally dominated by hydropower: 96% of the electricity produced in Quebec is hydro. In hydro dominated deregulated energy markets, a correlation can often be found between the water infl

Vi bor i galaxen Vintergatan. En plats som vi kan kalla hemma i ett allt växande universum. Men hur mycket vet vi egentligen om våran galax? Det finns mycket som återstår att upptäcka om våran galax. Ett exempel på någonting som vi inte vet hittas när vi observerar den galaktiska disken. Detta är regionen som expanderar horisontellt från det galaktiska centrumet. Disken är uppdelad i en tunn ochThis paper discusses the effects of different types of contamination on 4MOST stellar spectra. Three main types of contamination were tested. These were, a smooth function over the continuum, changing the H-alpha line, and adding telluric contamination. By knowing how much these experiments affected the generated values, it was possible to understand the importance of avoiding overfitting or under

Objective To assess the accuracy and reproducibility of ultrasound 'pattern recognition' for the diagnosis of borderline ovarian tumors by asking experienced ultrasound operators to evaluate representative images of different types of adnexal tumor. Methods Digitally stored static two-dimensional B-mode images of representative cases of benign, borderline and invasive malignant ovarian tumors were

The method of angular- and wavelength-dispersive (e.g. two-dimensional) Rietveld refinement is a new and emerging tool for the analysis of neutron diffraction data measured at time-of-flight instruments with large area detectors. Following the approach for one-dimensional refinements (using either scattering angle or time of flight), the first step at each beam time cycle is the calibration of the

Context. The first Gaia Data Release contains the Tycho-Gaia Astrometric Solution (TGAS). This is a subset of about 2 million stars for which, besides the position and photometry, the proper motion and parallax are calculated using Hipparcos and Tycho-2 positions in 1991.25 as prior information. Aims. We investigate the scientific potential and limitations of the TGAS component by means of the ast

ObjectivesIn Phase 1 of developing new hand osteoarthritis (OA) classification criteria, features associated with hand OA were identified in a population with hand complaints. Radiographic findings could better discriminate patients with hand OA and controls than clinical examination findings. The objective of Phase 2 was to achieve consensus on the features and their weights to be included in thr

Sediment transport pattern in the Himalayan River is complex and sediment sampling in these rivers are often difficult. Sediment load in the river varies largely from year to year. Major part of the sediment load is transported in the monsoon months. Reliable and consistent sediment rating equation is not found for the Himalayan Rivers. The change in the flow rate and suspended sediment concentrat
