Species abundance is often spatially structured such that, within a species’ distribution, abundance peaks at one or more areas and declines from those points. Abundance may also increase or decrease over time, but the spatial structure of temporal changes in abundance has been infrequently examined. Here we use count data from the North American Breeding Bird Survey (BBS) to describe the spatial
Temperature is a fundamental thermodynamic parameter used to describe physical, chemical and biological processes. In combustion as in many other applications, knowledge about temperature plays a substantial role in helping to maintain an efficient and clean environment Being able to measure temperature accurately in combustion and in fire-related applications is important for giving a better unde
The mechanoreceptive lateral line system in fishes detects hydrodynamic stimuli and plays a critical role in many fundamental behaviours, including orientation to water currents and the detection of stationary objects, prey and predators. Interspecific variation in lateral line structure may result from a process of functional adaptation, with the background level of hydrodynamic activity proposed
Twenty-five comparative cycle assessments (LCAs) addressing food waste treatment were reviewed, including the treatment alternatives landfill, thermal treatment, compost (small and large scale) and anaerobic digestion. The global warming potential related to these treatment alternatives varies largely amongst the studies. Large differences in relation to setting of system boundaries, methodologica
Processed food and eating out of the home are increasing phenomena, which presents new business opportunities for food manufacturers. However, the new food products require increased quality and safety, and thereby a more controlled distribution. The overall purpose of the research presented in this article is to describe the food supply chain from a critical context point of view in order to high
We investigated the association between cadmium in blood and the concentration of the prostate specific antigen (PSA) in semen, including the modifying effects of zinc or the CAG polymorphism in the androgen receptor (AR). Blood and semen samples were collected from 504 partners of pregnant women in Greenland, Poland and Ukraine. We found an inverse trend between cadmium and PSA (log (ß)= -0.121,
Populärvetenskaplig sammanfattning: Conodonterna var en framgångsrik och diversifierad marin djurgrupp som levde från ungefär mellankambrium (~ 500 Ma) till slutet av trias (200 Ma). Från ett fåtal bevarade avtryck vet man att djuren var långsmala, endast några cm långa och hade fenor. Avtrycken är svårtolkade, men mycket tyder på att conodonterna var förhållandevis avancerade och kanske till och Elements from the Ordovician conodont genus Protopanderodus Lindström, 1971 have been investigated to provide a model of reconstruction of the oral apparatus of this genus. In total, 4202 elements from the only five species representing Protopanderodus in the Swedish Middle Ordovician conodont fauna were included in the study. Four of the species, P. rectus, P. robustus, P. graeai and P. parvibasi
In the western world, strokes are the third most common cause of death, hitting mainly the elderly population. Smoking, high blood pressure, diabetes and overweight are known risk factors for causing strokes. Previous studies show that an increased level of particulate matter, PM, is also related to an increased number of strokes. The population in this study consists of patients over 65 years old
Aim: To study global patterns and temporal changes in the seasonal dynamics (quantity and seasonal distribution) of terrestrial gross carbon uptake in response to global environmental change. Location: Global. Time period: 2000–2016. Major taxa studied: Terrestrial ecosystems. Methods: Following a phenology-based definition of photosynthetic seasonality, we decompose gross primary production (GPP)
The steel and chemical production industries are the largest industrial emitters of greenhouse gases in the European Union, together accounting for half of the EU’s industrial greenhouse gas (GHG) emissions. A promising strategy for achieving deep GHG emissions reductions is the electrification of these two industries, which would depend on the rapid expansion of renewable electricity supply. Such
BackgroundComplete tumor resection is the most relevant prognostic factor for overall survival in high grade serous ovarian cancer (HGSOC) patients. The current standard for classification of postoperative residual disease (RD) is surgeon´s subjective evaluation at the end of surgery. Thus, a reliable objective predictive marker is currently missing.MethodsIn this prospective single-center feasibi
We recently reported that female patients with hypopituitarism receiving controlled thyroid and steroid hormone substitution, but without GH replacement, had a more than 2-fold increase in cardiovascular mortality compared to the general population. In the present study we investigated the incidence of cardiovascular disease as well as the prevalence of cardiovascular risk factors in 33 females wi
Studies investigating how the number of children in a family affects the parents or the children face problems because the variable of interestis endogenous in the model. The currently accepted solution to this problem is to use instrumental variables (IVs), for example, based on twin births. In this paper, I review and add to the critique of IVs based on twin births and show that that there are
Background: This study aimed to assess chlamydia diagnostics in different clinic types, including internet-based self-sampling (IBSS). Furthermore, we investigated the incidence of chlamydia-associated complications. Methods: Data on Chlamydia trachomatis (CT) testing were retrieved from six healthcare regions in the years 2016–2023 across different categories of testing facilities. National data
Background: The purpose of this study was to analyse if there is a relationship between the directions of windswept hip deformity and scoliosis for children with cerebral palsy (CP) and to explore potential associations with spasticity, contractures and hip displacement. Methods: A cross-sectional registry-based study was conducted using data from the combined Swedish CP Follow-up Program and Nati
With the increasing focus on reducing emissions and making fuel efficient vehicles within the automotive industry over the past few years, new methods are constantly being investigated to improve the efficiency of the powertrain. One such method is recovering waste heat from the exhaust gases as well as the coolant using a thermodynamic cycle such as a Rankine cycle. However, most studies looking
OBJECTIVE: The aim of this study was to describe and present the outcomes of a specific treatment protocol for aortic vascular graft and endograft infections (VGEIs) without explantation of the infected graft.METHODS: This was a retrospective, observational single centre cohort study carried out between 2012 and 2022 at a tertiary hospital. An aortic VGEI was defined according to the Management of
