Diagnostic reference levels (DRLs) were introduced as a tool to optimize radiation protection in medical imaging. Conditions for dose assessment have evolved significantly. This study explores how effectively the current DRL system functions and whether it requires adjustment. The analysis focuses on the national DRL system in Sweden and includes European projects and guidelines for reference. The
Improving energy efficiency in agriculture is key to reducing environmental impact. Lighting in animal buildings is one of the most cost‐effective energy saving measures. Lighting retrofit offers a short payback period, enhances animal welfare and production, and aligns with regulations for phasing out fluorescent lighting. The purpose of this study was to investigate the energy-saving potential o
BACKGROUND: Drug-coated devices are widely used to reduce restenosis after lower limb revascularisation in patients with peripheral artery disease, but their effect on patient-centred outcomes remains unclear. We assessed the effect of paclitaxel-coated devices on clinically important outcomes in patients with intermittent claudication undergoing infrainguinal endovascular revascularisation.METHOD
We present a superconducting cavity-coupled double quantum dot (DQD) photodiode that achieves a maximum photon-to-electron conversion efficiency of 25% in the microwave domain. With a higher-quality-factor cavity and improved device design to prevent photon leakages through unwanted pathways, our device measures microwave signals down to the 100-aW power level and achieves sensitivity to probe mic
In this paper, we describe a system that automatically converts narratives into 3D scenes. The texts, written in Swedish, describe road accidents. One of the program’s key features is that it animates the generated scene using temporal relations between the events. We believe that this system is the first text-to-scene converter that is not restricted to invented narratives. The system consists of
Objective: No method has yet been established to summarise different objective indicators of social outcomes into one score. The study aimed to develop and test a simple, brief and meaningful index of social outcomes that can be used across a broad range of mental health studies and is potentially obtainable from routine documentation. Method: An index capturing employment, accommodation and livin
Results of numerical simulations are presented for flow past a stationary circular cylinder at low Reynolds numbers (Re=50-200). The simulations were carried out using a finite-volume code employing a fractional step method with second-order accuracy in both space and time. A sensitivity study on numerical parameters concerning the domain size, grid independence and time step resolution was carrie
Mother-tongue education can be seen as an important tool for minority children to gain or maintain proficiency in their mother-tongue. They will thereby uphold a cultural and social link to the country and culture of origin. Advocates of mother-tongue education in school also highlight the importance of knowing one’s mother-tongue for successful second language acquisition. Others argue that the f
Much has changed since the 1960s when the first scholarship on contemporary graffiti appeared. The current paper is an attempt to outline and contextualize a number of recurrent challenges facing researchers of graffiti and street art, as well as developments that have taken place in this scholarly field. The aim of creating this outline is to assist in increasing the amount, and improving the qua
The parasitoid wasp Nasonia vitripennis is an emerging genetic model for functional analysis of DNA methylation. Here, we characterize genome-wide methylation at a base-pair resolution, and compare these results to gene expression across five developmental stages and to methylation patterns reported in other insects. An accurate assessment of DNA methylation across the genome is accomplished using
The last two decades have seen a significant increase in the number and quality of cross-national measures of institutions, which are also covering longer and longer time spans. However, despite the considerable progress that has been made, important measurement issues linger. This chapter argues that the key future challenge for the measurement of institutions is how to square objective or direct
Metal cutting is a very common operation in the manufacturing industry. Drilling and other hole-making operations perhaps account for 50% of all metal cutting, according to some investigations. All metal cutting including drilling always produces burrs, as a by-product. Actually burrs are nothing but uncut metal at the beginning and at the end of the operations. Yet, despite burr's omnipresence in
This paper describes the distribution of accusative case and discusses the nature of the nominative / accusative distinction in the standard Germanic languages. In addition, it illustrates and discusses the well-known fact that inherent accusatives and certain other types of accusatives do not behave in accordance with Bruzio’s Generalization. In spite of these Non-Burzionian accusatives, there is
The 2008–2009 global financial crisis triggered ‘Green Energy Economy’ (GEE) policy packages to stimulate green growth in many countries. China soon became a leader and, supported by its 11th Five-Year Plan (2006–2010), devoted approximately one-third of its US$ 647 billion stimulus package to green energy technologies. Since then, numerous policy instruments have been implemented to encourage ‘Gr
Gastrointestinal (GI) symptoms are common in renal transplant recipients and are associated with impaired health-related quality of life (HRQoL). We investigated clinician attitudes to GI symptoms and HRQoL in these patients by surveying 145 nephrologists from Sweden, Denmark, Finland, and Norway. In total, 79 clinicians responded. They estimated that 20% of their patients experienced GI discomfor
During the 1920s, when the Swedish defence was under heavy debate, military and conservative forces on the right tried to turn the Swedish public opinion towards a climate more in favour of the defence by producing a big budget war film – Karl XII. In several senses the film became a great success. In Sweden the attendance figures were as high as one million (of a population of six) and the film w
Popular Abstract in Swedish Vi kan inte avslöja innehållet i våra tankar direkt, så hur kan vi närma oss de underliggande kognitiva processerna? Om vi vill lära oss mer om vad som försiggår i vår tankevärld, måste vi göra det indirekt, med hjälp av tankarnas yttre manifestationer. Det finns olika metoder som man kan ta till sin hjälp. I min avhandling kopplar jag ihop två ämnesområden, lingvistik In this thesis, I connect two disciplines, linguistics and vision research, and combine two methods, spoken language protocols and eye movement protocols, in order to cast light on the underlying cognitive processes. In a series of studies, I investigate the processual aspects of picture viewing and picture description. On the one hand, eye movements reflect human thought processes. It is easy to
The mutational mechanism underlying the striking diversity in MHC (major histocompatibility complex) genes in vertebrates is still controversial. In order to evaluate the role of inter- and intragenic recombination in MHC gene diversification, we examined patterns of nucleotide polymorphism across an exon/intron boundary in a sample of 31 MHC class IIB sequences of three-spined stickleback (Gaster
