Breathlessness is common in the general population. Existing data were obtained primarily with the uni-dimensional modified Medical Research Council breathlessness scale (mMRC) that does not assess intensities of unpleasantness nor physical, emotional and affective dimensions. The aim of this research was to determine the prevalence and intensity of these dimensions of breathlessness in elderly ma
Background: Some studies have shown that cadmium (Cd) is associated with breast cancer risk. One hypothesis is that Cd has estrogen-like properties. This case-control study investigated the association between breast cancer risk and blood Cd (BCd) levels. Methods: All breast cancers in the Malmö Diet and Cancer cohort were identified through linkage to the Swedish Cancer Registry, baseline (1991-1
Kemisk vittring kallas processen när mineralkorn löses upp och sönderdelas i molekyler eller atomer. Det är en viktig process, bland annat för att den frigör ämnen som skyddar marken från försurning och som fungerar som näringsämnen för växter. För de så kallade baskatjonerna kalium, kalcium, magnesium och natrium är vittringen i marken bland de största källorna. Framför allt de tre förstnämnda baBase cations are important in forest soils as nutrients for vegetation and protection against soil acidification. Today, base cations have been lost from soils through acidification and forest harvesting. With low levels in soils, temporary situations of deficiency could occur. One of the largest inputs of base cations to soils is minerals weathering, which makes it an important process. It is, ho
The Swedish response to the pandemic at the national level has attracted considerable international attention, but little focus has been placed on the way municipalities dealt with the crisis. Using Hay's dimensions of politicization, namely the capacity for human agency, deliberation in the public domain, and social context, we analyze the politicization of the municipal response to the pandemic
If humans eventually attain the ability to create new life forms, how will it affect the value of life? This is one of several questions that can be sources of concern when discussing synthetic life, but is the concern justified? In an attempt to answer this question, I have analyzed some possible reasons why an ability to create synthetic life would threaten the value of life in general (that is,
Study objective: We aim to describe the variability and identify gaps in preparedness and response to the coronavirus disease 2019 pandemic in European emergency departments (EDs) caring for children. Methods: A cross-sectional point-prevalence survey was developed and disseminated through the pediatric emergency medicine research networks for Europe (Research in European Pediatric Emergency Medic
In this article, we propose new tests of equal predictive ability between nested models when factor-augmented regressions are used to forecast. In contrast to the previous literature, the unknown factors are not estimated by principal components but by the common correlated effects (CCE) approach, which employs cross-sectional averages of blocks of variables. This makes for easy interpretation of
This paper investigates the performance of a microgrid with droop-controlled inverters in terms of the total power losses incurred in maintaining synchrony under persistent small disturbances. The inverters are modeled with variable frequencies and voltages under droop control. For small fluctuations from a steady state, these transient power losses can be quantified by an input-output H2 norm of
Vibronic coupling between molecules has been recently discussed to play an important role in photosynthetic functions. Furthermore, this type of coupling between electronic states has been suggested to define photophysical properties of chlorophylls, a family of photosynthetic molecules. However, experimental investigation of vibronic coupling presents a major challenge. One subtle way to study vi
The notion of ‘post-truth’ has attracted considerable interest both in academic and political circles, as well as in public debate more generally. A ‘post-truth society’ has been defined as a society in which ‘“objective facts” are less influential in shaping public opinion than appeals to emotion and personal belief’. This also implies a society in which fake news is disseminated on purpose and w
This paper draws on two ethnographic research projects in Japanese university sports clubs to examine the role alcohol plays in the social and cultural education of students. Over the course of a four-year membership, the university sports club is a site where members learn to negotiate drinking. This negotiation is demonstrated by the range of strategies members employ when engaging in one of the
Vertical-beam entomological radars provide precise measurements of the body alignment of individual overflying insects but are unable to distinguish which of the two axial directions the insect is heading towards. Insects migrating at altitude typically show common alignment, although with a broad spread. We show here that when observations from multiple individual insects are available, and the i
In Europe, all new houses built require an energy declaration showing the expected energy consumption during use. However, there is often a discrepancy between the calculated and the actual energy consumption. Some claim that in general the difference is on the positive side for wooden buildings, with real energy consumption being lower than predicted. This could be an effect of thorough and long-
The large-scale impact of urbanization on wildlife is rather well documented; however, the mechanisms underlying the effects of urban environments on animal physiology and behaviour are still poorly understood. Here, we focused on one major urban pollutant – artificial light at night (ALAN) – and its effects on the capacity to mount an innate immune response in wild great tit (Parus major) nestlin
Pressure transduction to the wound bed in negative pressure wound therapy (NPWT) is crucial in stimulating the biological effects ultimately resulting in wound healing. In clinical practice, either foam or gauze is used as wound filler. Furthermore, two different drainage techniques are frequently employed. One involves the connection of a non-perforated drainage tube to the top of the dressing, w
OBJECTIVE: To test whether a previously hypertension-linked 23 cM region on chromosome 2 is linked to the metabolic syndrome (MetS) or its individual components, and whether a common I/D polymorphism of the adrenergic receptor 2b (ADRA2B) gene, mapping in that region, is associated with the same traits. METHODS: We conducted fine mapping of the hypertension-linked region on chromosome 2 spanning b
The fact that Jesus was a man is claimed to be problematic from a feministic standpoint. One aspect of what is problematic is that the conception of Jesus as the Christ, representing God, makes the connection between men and God closer that that between women and God. In terms of religious proximity men are given a higher degree of religious proximity and therefore also religious authority by mean
In atrial fibrillation (AF), the body surface signal pattern varies considerably from one patient to another as well as over time. We have developed a new method for ECG-based characterization of AF which explores the morphology of the f-waves. Following QRST cancellation, the method divides the atrial signal into short blocks and performs a model-based analysis of each block. The blocks are then
Popular Abstract in Swedish Våglängden för röntgenstrålning är mycket kortare än den för synligt ljus. I själva verket är den jämförbar med avståndet mellan atomer i fasta material, vilket är i storleksordningen en tiondels nanometer. Genom att använda ljus med så kort våglängd är det möjligt att studera materials struktur på atomär nivå. Spridning av röntgenstrålar har utvecklats till ett ovärder
