The signal crayfish (Pacifastacus leniusculus) was introduced to Sweden in 1960, and it has a high commercial and recreational value, but it may also have negative effects on native ecosystems. To better predict how climate warming will affect population dynamics of this cool-water crayfish, we explored the role of temperature and density dependence as explanatory factors of the subsequent years’
A research-based understanding of permafrost distribution at a sufficient spatial resolution is important to meet the demands of science, education and society. We present a new permafrost map for Norway, Sweden and Finland that provides a more detailed and updated description of permafrost distribution in this area than previously available. We implemented the CryoGRID1 model at 1km2 resolution,
The number of cancer survivors continues to increase worldwide. Many of these survivors have had children of their own. It is less well-known whether radiation therapy or chemotherapy could affect the risk of stillbirth and neonatal death for these children. To explore this research questions, we identified all women diagnosed with cancer between 1958 and 2012 from the Swedish Cancer Register and
AIMS AND OBJECTIVES: To investigate the experience and personal impact of a group leadership course for child healthcare nurses.BACKGROUND: During their child's first year, all parents in Sweden are invited to participate in parental groups within the child health service; however, only 49% choose to participate. Despite extensive experience, child healthcare nurses find managing parental groups c
Our understanding of fundamental organismal biology has been disproportionately influenced by studies of a relatively small number of ‘model’ species extensively studied in captivity. Laboratory populations of model species are commonly subject to a number of forms of past and current selection that may affect experimental outcomes. Here, we examine these processes and their outcomes in one of the
Several studies have shown associations between shorter telomere length in blood and weakened immune function, susceptibility to infections, and increased risk of morbidity and mortality. Recently, we have shown that malaria accelerates telomere attrition in blood cells and shortens lifespan in birds. However, the impact of infections on telomere attrition in different body tissues within an indiv
In continental margin basins, the hydrogeological setting is complex due to transgression/regression events that removed old sediments in the basin and formed new geologic units. Due to the geological complexity, the use of vertical electrical sounding has proven to be insufficient for groundwater explorations. The lack of understanding the geological underground has resulted in many boreholes wit
The potato onion ‘Leksand’, the soapwort ‘Kvinnsgröta’, and the geranium ‘Drottningminne’ are since a few years officially authorized Swedish heritage plants. They are all named after places; a small town in Dalecarlia, a village on the island Öland and a farmstead in the northern region Jämtland. This presentation will discuss how heritage plants are made, in processes which comprise social and p
A recent slew of ENCyclopedia Of DNA Elements (ENCODE) Consortium publications, specifically the article signed by all Consortium members, put forward the idea that more than 80% of the human genome is functional. This claim flies in the face of current estimates according to which the fraction of the genome that is evolutionarily conserved through purifying selection is less than 10%. Thus, accor
Both numerical simulations and experiments were conducted in a heavy-duty DICI engine, with PRF81 as a gasoline surrogate, to investigate how the fuel stratification, auto-ignition and combustion are affected by the start of injection (SOI). The intake air temperature was adjusted to keep the combustion phasing constant when the SOI was swept from −100 to −20 oCA ATDC, covering different regimes o
PurposeThe aim of the present study was to identify the most physically demanding work tasks for Swedish ground combat soldiers through the development and application of a questionnaire survey. This is the first in a series of studies aiming to describe the development process and validation of physical selection standards in the Swedish armed forces.MethodsBased on procedural documentation, comb
Background and purpose — Children and young adults with cerebral palsy (CP) have an increased risk of developing scoliosis, with a prevalence ranging from 11% to 29%. Information on risk factors for the emergence and progression of scoliosis is inconclusive. This study aimed to develop a risk score based on 5-year-old children with CP to predict the risk of scoliosis before the age of 16. Patients
An experimental study on the duration of load effects in a glued shear plate dowel joint was conducted. The joint design features a single large diameter dowel for load transfers between members, via external steel plates, which are bonded to the timber with a low stiffness bond line. Due to the low bond line stiffness, the timber element is subjected to a close to uniform shear stress distributio
Migratory songbirds are guided by an endogenous programme during their first migration, encoding timing of migration, distance and direction. To successfully perform migration, birds have evolved phenotypic adaptations for flight, fuelling and navigation. Migratory distance in different species of birds is encoded as a period of expressed migratory restlessness, for which the length is correlated
Objective. An increased risk of being diagnosed with coronary heart disease or atrial fibrillation has been shown among different immigrant groups. However, less is known on the risk of being diagnosed with congestive heart failure (CHF). Design. We studied CHF in immigrants including all adults ≥45 years in Sweden (n = 3,274,119) from 1998 to 2012. CHF was defined as at the first event registered
Background Recent policy in Sweden states that patients in every part of health care are to be presented with health counselling concerning living habits: tobacco, alcohol, an inactive lifestyle and eating habits. This review aims to investigate experiences and preferences of counselling about living habits from the patient’s perspective. Method A literature review of six major databases using a
Background. Because of the relative rarity of breast cancer in males, data have not been sufficient to support a definitive analysis of pertinent prognostic factors. Remarkably, no studies of male patients with breast cancer have presented survival information based on the number of histologically positive axillary nodes, the most sensitive single indicator of prognosis in women with breast cancer
The present study aimed to study the relation between the release of arachidonic acid (AA) and the energy state in cerebral cortices of rats during single episodes of cortical spreading depression (CSD). The changes in concentrations of AA, labile phosphate compounds [ATP, ADP, AMP, and phosphocreatine (PCr)], and glycolytic metabolites (lactate, pyruvate, glucose, and glycogen) were studied durin
This paper considers the long-term effects of smoking on disability retirement in Sweden. Smoking is known to have damaging effects on health, but there is limited evidence on how the effects of smoking translate into worse labour market outcomes, such as the inability to work. In contrast to the few previous studies on smoking and disability retirement, we use a large population sample with regis
