Context. The Galactic bulge is an intriguing and significant part of our Galaxy, but it is hard to observe because it is both distant and covered by dust in the disk. Therefore, there are not many high-resolution optical spectra of bulge stars with large wavelength coverage, whose determined abundances can be compared with nearby, similarly analyzed stellar samples. Aims. We aim to determine the d
The focus of this article is to undertake a comparative analysis of multi-step-ahead linear multivariate predictors. The approach considered for the estimation will be based on geometrically reliable linear algebra tools, resorting to subspace identification methods. A crucial issue is quantification of both bias error and variance affecting the estimate of the prediction for increasing values of
Advances in scheduling theory have given designers of control systems greater flexibility over their choice of timing requirements. This could lead to systems becoming more responsive and more maintainable. However, experience has shown that engineers find it difficult to exploit these advantages due to the difficulty in determining the “real” timing requirements of systems and therefore the techn
Lack of straightness in timber is the most frequent complaint regarding solid (and laminated) timber products worldwide. Nowadays, customers demand higher quality in the shape stability of wood products than they did earlier. The final distortion of timber boards is mostly caused by moisture-related stresses in wood (drying distortions) and growth-related stresses (distortions appearing when logs
In phenotype experiments in mice, determination of dynamic insulin sensitivity often uses the insulin tolerance test. However, the interpretation of this test is complicated by the counterregulation occurring at low glucose. To overcome this problem, we determined the dynamic insulin sensitivity after inhibition of endogenous insulin secretion by diazoxide (25 mg/kg) in association with intravenou
This thesis consists of a collection of essays on coordination in games and competition in international oligopolies. The first essay presents a theoretical analysis of a simple coordination game in which players simultaneously choose efforts from a compact interval. The original game has a continuum of Pareto-ranked equilibria. In a noisy variant of the model an error term is added to each player
The apparent permeability index is widely used as part of a general screening process to study drug absorption, and is routinely obtained from in vitro or ex vivo experiments. A classical example, widely used in the pharmaceutical industry, is the in vitro Caco-2 cell culture model. The index is defined as the initial flux of compound through the membrane (normalized by membrane surface area and d
Avhandlingen belyser mötet mellan de konstnärliga och pedagogiska dimensionerna i lärares pedagogiska arbete. Genom att undersöka lärares erfarenheter av musikalproduktion i skolan avser studien att fördjupa kunskapen om det professionella lärararbetet som grundar sig i lärares pedagogiska och konstnärliga utövande och praktiska kunskap. Studien tar sin utgångspunkt i en musikalproducerande verksa
In this chapter, we explore whether eyeblinks can be used as a measurementof spectators’ narrative transportation into a cinematic narrative. In ourexperiment, we show that spectators’ eyeblinks increase when watchingfilm clips together with what might be called congruent music. Increasedeyeblinks indicate an emotional arousal that motivates attention, whichin turn is a prerequisite for narrative
Sensors used for control have become widespread in water resources recovery facilities during the strive for resource efficient operations. However, their accuracy is reliant on uncertain laboratory measurements, which are used for calibration and, in turn, to correct for sensor drift. At the same time, current sensor calibration practices are lacking clear theoretical understanding of how measure
Firefighters are occupationally exposed to a large number of toxic compounds (IARC 2010). The occupational exposure of firefighters has been classified as potentially carcinogenic (class 2B, IARC; (Straif K. et al. 2007)). Poorly quantified emission factors and low understanding of when various aerosol emissions are likely to form during a fire event (initiation, combustion, extinguishing) inhibit
This paper explores the processing of sensitive personal data for genealogical purposes by studying how the privacy policies of three direct-to-consumer genetic testing companies relate to the general Data Protection Regulation (GDPR). The methodological approach is content analysis. The privacy policies are analysed in relation to the three core principles of 1) adherence to GDPR; 2) transparent
AbstractAim: The overall aim of the thesis was to examine the psychosocial effects and family reactions to participation in longitudinal studies with their children at high risk for type 1 diabetes. Additionally, we aimed to develop a shorter form for the children to measure their anxiety when thinking of their risk of developing type 1 diabetes, which could be used in The Environmental Determinan
Control of crop pests by shifting host plant availability and natural enemy activity at landscape scales has great potential to enhance the sustainability of agriculture. However, mainstreaming natural pest control requires improved understanding of how its benefits can be realized across a variety of agroecologies. Empirical studies suggest significant but highly variable responses of natural pes
Micron-sized aluminum (Al) particles have recently been proposed as promising carbon-free energy carriers. To facilitate the application of micron-sized Al particles as fuel in practical energy generation system, this study experimentally investigates the underlying mechanisms of the ignition, stabilization and particle-particle collision in lifted Al particle cloud flames. High-resolution shadowg
The processes responsible for the formation of Earth's most conspicuous diversity pattern, the latitudinal diversity gradient (LDG), remain unexplored for many clades in the Tree of Life. Here, we present a densely sampled and dated molecular phylogeny for the most speciose clade of damselflies worldwide (Odonata: Coenagrionoidea) and investigate the role of time, macroevolutionary processes, and
BACKGROUND: After surgery for oesophageal or gastric cancer, patients suffer from a variety of problems that affect their physical and mental health. Most previous studies on quality of life after this type of surgery are based on quantitative methods, and no studies to date have focused on the patient's subjective experiences of their quality of life from a long-term perspective. OBJECTIVE: To il
