A pre-requisite to reach the EU 2030 and beyond targets is a significantly increased ambition among property owners regarding energy-efficient refurbishments. The Swedish Energy Agency and the National Board of Housing, Building and Planning are on the Swedish government assignment developing a strategy with policy instruments to increase energy-efficiency oriented renovation. In order to design t
Historians have long been interested in knowledge—its nature and origin, and the circumstances under which it was created—but it has only been in recent years that the history of knowledge has emerged as an academic field in its own right.In "Circulation of Knowledge", a group of Nordic scholars explore a range of theoretical and methodological approaches to this new and exciting area of histori
Serum determinations of the glial protein S100B has been found to correlate with brain damage after cardiac surgery. Forty-eight hours and later after surgery, increased S100B levels correlates with the presence of brain infarction, and the extent of infracted brain tissue. S100B at this time-point has been shown to predict long-term outcome, higher S100B levels correlated with decreased survival.
OBJECTIVE: To study the relationship between smoking and chronic pain among people aged 65+ years. DESIGN: A cross-sectional study. SAMPLE: The study was carried out in 2011 and included a randomly selected (N = 2000, response rate 57%) sample of people aged 65 years and older, living in Sweden. MEASUREMENT: A postal questionnaire with questions about demographic data, living conditions, tobacco u
Background and purpose — The proximal femur locking compression plate (PF-LCP) is a new concept in the treatment of hip fractures. When releasing new implants onto the market, biomechanical studies are conducted to evaluate performance of the implant. We investigated the relation between biomechanical and clinical studies on PF-LCP. Methods — A systematic literature search of relevant biomechanica
När skottskogsbruket/stubbskottsängsbruket upphörde i början av 1800-talet försvann även landskapet som humlesugan, Betonica officinalis L., var anpassad till. Från att ha varit allmän på sydvästra Lolland och i västra Mellanskåne blev den mycket sällsynt inom dessa kärnområden i humlesugans tidigare utbred- ning i Skandinavien. Ändå lyckades den överleva på sju lokaler. För att bevara dessa krävsWhen coppice forestry and the use of wooded meadows ceased in the early 19th century, the landscape to which Betony, Betonica officinalis L., was adapted also disappeared. From being common in southwestern Lolland and in western MidSkåne, it became very rare in these core areas of Betony’s earlier distribution in Scandi navia. However, the species has managed to survive at seven localities and t
A competition process is a continuous time Markov chain that can be interpreted as a system of interacting birth-and-death processes, the components of which evolve subject to a competitive interaction. This paper is devoted to the study of the long-term behaviour of such a competition process, where a component of the process increases with a linear birth rate and decreases with a rate given by a
Experience of out-of-home care (OHC) is associated with life-long vulnerability, and research indicates that parents with experiences of OHC are at higher risk of having their own children placed in out-of-home care. However, research on these parents is limited and lacks a resilience perspective. Here, we focused on parents with OHC experience as children but with custody of their own children (N
We explain how the accelerating field amplitude and phase vary with modulator voltage in pulsed radio frequency high-power amplifiers based on klystron tubes. Changes in modulator voltage give rise to correlated changes of amplitude and phase, affecting the properties of the accelerated beam, in particular energy, arrival time, and bunch duration. We show, both theoretically and experimentally, th
The web of relationships between wellbeing and the environments in which people live has long been recognized. However, relatively little research has been conducted about end-of-life surroundings from the perspective of the dying person. In this study, we investigate which aspects of their surroundings are particularly meaningful for the people inhabiting them in the last phases of life, based on
On the day of the 2016 summer solstice, June 21, MAX IV, the new synchrotron radiation facility in Lund, Sweden, will be inaugurated. MAX IV is setting a new standard in terms of emittance, thereby providing beamlines with the best possible brilliance and coherence. At the same time, MAX IV continues a more than three-decades-long successful history of Swedish synchrotron-radiation-based research.
A simplistic approach to optimising medical imaging is to use the lowest effective dose to the patient that does not jeopardise a correct diagnosis. With limited resources and over 1000 different types of X-ray examinations, it is not always easy to set the right priorities and to decide how to perform the optimisation. Recent research shows that the 'Rose model' for the detection of specific stru
An extended Keldysh formalism, well suited to properly take into account the initial correlations, is used in order to deal with the time-dependent current response of a resonant tunneling system. We use a partition-free approach by Cini in which the whole system is in equilibrium before an external bias is switched on. No fictitious partitions are used. Despite a more involved formulation, this p
Background: Daycare infants have more infectious episodes, see a physician more often, and are prescribed antibiotics more often than home care infants. Aim: To compare physician consultations and antibiotic prescription in daycare children and home care children taking number of symptom days, sociodemographic factors, concern about infectious illness and antibiotic knowledge into account. Methods
Popular Abstract in Swedish Det råder delade meningar om hur man bäst tar hand om patienter med lindrig primär hyperparatyreoidism (PHPT), dvs. överfunktion i en eller flera av de fyra bisköldkörtlarna med endast lätt förhöjning av kalciumnivån i blodet. Det finns de som förordar operation, medan andra anser att det inte behövs någon behandling så länge sjukdomen inte förvärras. Syftet med det akt
Alkaline sphingomyelinase (alk-SMase) is present in the intestinal tract and additionally human bile. It hydrolyses sphingomyelin in both intestinal lumen and the mucosal membrane in a specific bile salt dependent manner. The enzyme was discovered 36 years ago but got real attention only in the last decade, when sphingomyelin metabolism was realized to be a source of multiple lipid messengers, and
Popular Abstract in Swedish Den dansk-svenske forfatter Gustaf Munch-Petersen (1912-1938) betragtes som en af portalskikkelserne i den danske lyriske modernisme. Han døde 26 år gammel som frivillig i den spanske borgerkrig, en konflikt, vi i dag ofte betragter som en del af optakten til anden verdenskrig. Dette tidlige endeligt gjorde ham til en af skandinavisk litteraturs ”unge døde”. Men det er
