Around 20 % of all electrical energy goes to lighting. There is a strong need to make this figure lower. Our research group has for more than a decade worked with the problem how to reduce the energy use for lighting, but at the same time provide better lighting conditions to meet human needs. The work comprises both laboratory studies and field studies. Two different tracks have been used: One th
The design of buildings has mainly focused on energy performances during the last decades however, it is also important to emphasize human needs and behaviour. Our research projects aim to advance knowledge of sustainability concepts in building design by investigating how buildings communicate with users towards sustainability, how are buildings perceived and used, and the roles of the individual
The water flea Daphnia has the capacity to respond rapidly to environmental stressors, to disperse over large geographical scales, and to preserve its genetic material by forming egg banks in the sediment. Spatial and temporal distributions of D. magna have been extensively studied over the last decades using behavioral or genetic tools, although the correlation between the two has rarely been the
Animal coloration is a multifaceted trait with many ecological roles and related to a variety of developmental and physiological processes. Consequently, coloration is often subject to a variety of selective pressures, leading to the evolutionary maintenance of variation. In this study, we investigated hypotheses related to the maintenance of dorsal color variation in wood frogs (Rana sylvatica).
Conservation efforts have mainly been focused on depleted species or populations, but many formerly reduced marine mammal populations have recovered to historical abundances. This calls for new management strategies and new models for ecological risk assessment that incorporate local density dependence and multiple environmental stressors. The harbor seal metapopulation in Swedish and Danish water
Lymphoid organ hypertrophy is a characteristic feature of acute infection and is considered to enable efficient induction of adaptive immune responses. Accordingly, oral infection with rotavirus induced a robust increase in cellularity in the mesenteric LNs, whose kinetics correlated with viral load and was caused by halted lymphocyte egress and increased recruitment of cells without altered cellu
Plants have always been powerful symbols of place, rooted as they are in the local soil. Yet in the Chinese lunar calendar, flowers and plants are also core images for defining and representing seasonal aspects of time. Through a conceptualization of qingjing (情境) that relates literary poesis to emotional interaction with the environment, this chapter executes a thematic comparison of arboreal cha
Past research on the effect of oxygen concentration on the heat release rate and carbon monoxide yield has focused on materials in isolation and there is a lack of research that studies end-use products. This paper investigates the effect of oxygen concentration on the heat release rate per unit area (HRRPUA) and carbon monoxide yield for two different cables and a mineral oil used as an operating
Since the 1990s, extensive urbanization in East Asia has created a situation in which more people identify themselves as citizens of the city where they live, rather than their ancestral village or nation. At the same time, this new urban identity has been under constant threat from massive municipal restructuring. Such rapidly changing cityscapes form environments of urban flux that lead to narra
To explore the largely unknown etiology of small intestine cancer, we examined metabolic factors and risk of small intestine cancer overall and by subtypes. Among 404 220 women and 403 265 men in six European cohorts, we applied Cox regression with adjustment for smoking and body mass index (BMI), to calculate sex-specific hazard ratios (HRs) of small intestine cancer by levels of BMI, mean arteri
Late mortality of European 5-year survivors of childhood or adolescent cancer has dropped over the last 60 years, but excess mortality persists. There is little information concerning secular trends in cause-specific mortality among older European survivors. PanCareSurFup pooled data from 12 cancer registries and clinics in 11 European countries from 77 423 five-year survivors of cancer diagnosed

Bone mineral density (BMD) is an established measure used to diagnose patients with osteoporosis. In clinical trials, change in BMD has been shown to provide a reliable estimate of fracture risk reduction, and achieved BMD T-score has been shown to reflect the near-term risk of fracture. We aimed to test the association between BMD T-score and fracture risk in patients treated for osteoporosis in
This collaborative statement from the International Society for Holter and Noninvasive Electrocardiology/Heart Rhythm Society/European Heart Rhythm Association/Asia Pacific Heart Rhythm Society describes the current status of mobile health (“mHealth”) technologies in arrhythmia management. The range of digital medical tools and heart rhythm disorders that they may be applied to and clinical decisi
Celiac disease is a chronic small bowel disease induced by ingestion of gluten in genetically susceptible individuals affecting 1% among Caucasians in the Western world. The prevalence of celiac disease is still unknown in most developing countries, especially in Africa which suffer from lack of resources to perform screening of the general population. The aim of this study was to determine the pr
Whether free returns create economic value for online retailers is a question of increasing importance. Using order-level data from an online fashion retailer in Sweden, we investigate the introduction of free returns for customers in Denmark starting November 1, 2017, but not for customers in Sweden, Norway, Finland, France, Germany, and the rest of Europe (the control group). Using difference-in
Overtourism encapsulates the zeitgeist of contemporary tourism and was - for a few years - the buzzword within media reports on tourism. It gained attention as an unsustainable consequence of the intensification of place management practices in urban economic planning strategy. Stories about “the invasion” of visitors into a number of popular European cities frequently circulated in news and socia
This overview of progress made in preventing post-traumatic osteoarthritis (PTOA) was delivered in a workshop at the Orthopaedics Research Society Annual Conference in 2019. As joint trauma is a major risk factor for OA, defining the molecular changes within the joint at the time of injury may enable the targeting of biological processes to prevent later disease. Animal models have been used to te
Objectives/Hypothesis: The aims were to determine health-related quality of life (HRQoL), including voice problems, dysphagia, depression, and anxiety after total laryngectomy (TL), and investigate the associations between HRQoL and the late effects. Study Design: Cross-sectional study. Methods: 172 participants having received a TL 1.6 to 18.1 years ago for laryngeal/hypopharyngeal cancer filled
