Genetic structure in the species-pair Silene vulgaris and S. uniflora (caryophyllaceae) on the Baltic island of Öland

Allozyme data were used to assess the genetic structure between 37 sympatric populations of the species-pair Silene vulgaris and S. uniflora ssp. petraea, and to infer levels of intra- and interspecific gene flow in the two species. Silene vulgaris is a geographically widespread weed of disturbed habitats whereas S. uniflora ssp. petraea is endemic to the Baltic islands of Öland and Gotland. On Öl

Risk Factors for Tibial Component Loosening : A Meta-Analysis of Long-Term Follow-up Radiostereometric Analysis Data

BACKGROUND: Radiostereometric analysis (RSA) is a highly accurate tool to detect implant migration and predict loosening following total knee arthroplasty (TKA). However, little is known about the predisposing risk factors for implant migration, nor which migration profile should be considered physiological (i.e., merely part of an implant-settling phase) and which should be considered pathologica

Group hunting in harbour porpoises (Phocoena phocoena)

Cooperative hunting involves individual predators relating in time and space to each other’s actions to more efficiently track down and catch prey. The evolution of advanced cognitive abilities and sociality in animals are strongly associated with cooperative hunting abilities as has been shown in lions, chimpanzees, and dolphins. Much less is known about cooperative hunting in seemingly unsocial

Core and Valence Level Photoelectron Spectroscopy of Nanosolvated KCl

The solvation of alkali and halide ions in the aqueous environment has been a subject of intense experimental and theoretical research with multidisciplinary interests; yet, a comprehensive molecular-level understanding has still not been obtained. In recent years, electron spectroscopy has been increasingly applied to study the electronic and structural properties of aqueous ions with implication

In Search of Search (& its Engines)

Research notes & miscellany from a research group focused on the intersection between media & information literacies and search, search engines, and search-adjacent recommender systems. Based at Lund University’s Pufendorf Institute for Advanced Studies.

Factors contributing to survival and evacuation in residential fires involving older adults in Sweden

It has been known for a long time that older adults suffer a significantly higher risk of dying in residential fires compared to younger people. The characteristics of these fatal fires and the fatalities are also well known. However, less is known about older adults who survive fires and how they differ from those who die. This distinction can be assumed to be of great importance when designing e

Structural Brain Correlates of the Externalizing Spectrum in Young Adults

The externalizing spectrum, including traits and behaviors such as aggression, reduced inhibitiory control and substance abuse, is associated with altered prefrontal brain morphology. However, the degree to which different manifestations of the externalizing spectrum are associated with distinct or overlapping variations in individual brain morphology is unclear. Here, we therefore used structural

Socioeconomic and clinical predictors of mortality in patients with acute dyspnea

Background: Factors predicting long-term prognosis in patients with acute dyspnea may guide both acute management and follow-up. The aim of this study was to identify socioeconomic and clinical risk factors for all-cause mortality among acute dyspnea patients admitted to an Emergency Department. Methods: We included 798 patients with acute dyspnea admitted to the ED of Skåne University Hospital, M

Emission reduction strategies in the EU steel industry : Implications for business model innovation

The European steel industry must achieve deep greenhouse gas emission reductions to become climate neutral by 2050. New business models are often proposed as one of the key solutions but are mostly addressed in general terms, without elaborating on or systematically analyzing how these new business models are actually linked to specific mitigation measures or strategies. In this paper, we assess w

Assessing Future Resilience, Equity, and Sustainability in Scenario Planning

In the absence of strong international agreements, many municipal governments are leading efforts to build resilience to climate change in general and to extreme weather events in particular. However, it is notoriously difficult to guide and activate processes of change in complex adaptive systems such as cities. Participatory scenario planning with city professionals and members of civil society

RIFM fragrance ingredient safety assessment, 5- and 6-decenoic acid, CAS Registry Number 72881-27-7

Summary: The existing information supports the use of this material as described in this safety assessment. 5- and 6-Decenoic acid was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data from read-across analog oleic acid (CAS # 112-80-1) show that 5- and 6-deceno

The Assassination of Fakhrizadeh—A Major Iranian Counterintelligence Failure?

The assassination of Iranian top nuclear scientist Mohsen Fakhrizadeh is one of numerous assassinations in Iran conducted by foreign powers ever since 2007. In the past six months, assassins have in addition to Fakhrizadeh also been able to kill Al-Qaida’s no. 2 on Iranian soil. The three most important organizations in the Iranian intelligence community are the Ministry of Intelligence, as well a

Mortality after Ischemic Stroke in Patients with Alzheimer's Disease Dementia and Other Dementia Disorders

Background: Stroke and dementia are interrelated diseases and risk for both increases with age. Even though stroke incidence and age-standardized death rates have decreased due to prevention of stroke risk factors, increased utilization of reperfusion therapies, and other changes in healthcare, the absolute numbers are increasing due to population growth and aging. Objective: To analyze predictors

Innovation in the long run: Perspectives on technological transitions in Sweden 1908-2016

There are fundamental unresolved questions about the nature of the long-run interplay between innovation and economic development processes. This study examines technological transitions in Sweden, 1908-2016, using a new literature-based innovation output indicator for the engineering industry, allowing a mixed-methods approach. The results suggest that waves of innovation have taken place during

Experimental wildfire induced mobility of radiocesium in a boreal forest environment

Wildfires are expected to increase with warmer climate, which can contribute to the mobility and the resuspension of long-lived and potentially hazardous radionuclides. The release of 137Cs during combustion of dried litter, forest floor organic soil, and peat was investigated in a small-scale experimental set-up. Combustion conditions were varied to simulate different wildfire scenarios, and the

Region-specific radioecological evaluation of accidental releases of radionuclides from ESS

Gadolinium-148 is one of the radionuclides of most concern that will be produced in the tungsten target of the European Spallation Source (ESS), as a by-product of the spallation reaction used by the facility to produce neutrons. Since 148Gd a pure alpha emitter, it is both very radiotoxic and difficult to measure. With its half-life of 75 years, it will remain in the environment for a long time i

Resonance in dialogue : The interplay between intersubjective motivations and cognitive facilitation

Dialogic resonance, when speakers reproduce constructions from prior turns, is a compelling type of coordination in everyday conversation. This study takes its starting point in resonance in stance-taking sequences with the aim to account for the interplay between intersubjective motivations and cognitive facilitation in resonance production. It analyzes stance-taking sequences in the London–Lund
