Purpose The prevalence of hip and groin problems in professional male ice hockey is unknown and suspected to differ between playing positions. The purpose of this study was to explore potential differences in the seasonal prevalence of hip and groin problems between playing positions in male elite ice hockey players and to explore the relationship between symptom duration and hip and groin functi
The main purpose of this article is to examine how elite athletes perceive their own responsibilities and possibilities to be compliant with the anti-doping regulations, and to draw conclusions about what these perceptions mean in relation to the legitimacy of the anti-doping system. A qualitative research design, with interviews conducted with athletes globally, was employed to capture elite spor
In 1822 the Parliament of the United Kingdom passed The Cruel Treatment of Cattle Act, which today is considered to be an important forerunner to modern animal protection and anti-cruelty legislation. However, the new Enlightenment attitudes to animals stemmed from an overly anthropocentric perception of the natural world and the place of the human animal in it. At the heart of the movement agains
The globular clusters of large spiral galaxies can be divided into two populations: one that formed in situ and one that comprises clusters tidally stripped away from other galaxies. In this paper, we investigate the contribution to the outer globular cluster population in the M31 galaxy through donation of clusters from dwarf galaxies. We test this numerically by comparing the contribution of glo
In order to characterize the radium distribution and submarine groundwater discharge (SGD) in the Bohai Sea area, the three isotopes 223Ra, 224Ra and 228Ra in different water bodies were measured in a 4-year period with the radium-delayed coincidence counting (RaDeCC) system. The results indicated that radium activities take an order of groundwater > coastal seawater > river water > central seawat
Background Genetic determinants of stroke, the leading neurological cause of death and disability, are poorly understood and have seldom been explored in the general population. Our aim was to identify additional loci for stroke by doing a meta-analysis of genome-wide association studies. Methods For the discovery sample, we did a genome-wide analysis of common genetic variants associated with inc
This summary refers to the paper 'Comparison of the FMEA and STPA safety analysis methods-a case study' [Su17]. The paper was published as an article in the Software Quality Journal. It compares the Failure Mode and Effect Analysis (FMEA) and the System Theoretic Process Analysis (STPA) in an industrial case study.
Segmenting a motion-planning problem into smaller subproblems could be beneficial in terms of computational complexity. This observation is used as a basis for a new sub-maneuver decomposition approach investigated in this paper in the context of optimal evasive maneuvers for autonomous ground vehicles. The recently published alternating augmented Lagrangianmethod is adopted and leveraged on, whic
This article aims at describing a logistic approach for prolonged resuscitation efforts in the cath-lab using mechanical chest compressions (MCC) during simultaneous percutaneous coronary intervention (PCI).
As our society becomes more and more dependent on IT systems, failures of these systems can harm more and more people and organizations. Diligently performing risk and hazard analysis helps to minimize the potential harm of IT system failures on the society and increases the probability of their undisturbed operation. Risk and hazard analysis is an important activity for the development and operat
Purpose Asthma is frequently reported in endurance athletes. The aim of the present study was to assess the long-term airway inflammatory response to endurance exercise in high-level athletes with and without asthma. Methods In a cross-sectional design, 20 asthmatic athletes (10 swimmers and 10 cross-country skiers), 19 athletes without asthma (10 swimmers and 9 cross-country skiers), and 24 healt
STUDY DESIGN: Study protocol for a randomized controlled trial and a prospective cohort. BACKGROUND: The number of arthroscopic surgical procedures for patients with femoroacetabular impingement syndrome (FAIS) has significantly increased worldwide, but high-quality evidence of the effect of such interventions is lacking. OBJECTIVES: The primary objective will be to determine the efficacy of hip a
Det terrestra ekosystemet absorberar cirka en tredjedel av de antropogena utsläppen varje år, vilket är en avgörande ekosystemtjänst som minskar ökningstakten av atmosfärisk koldioxid och bidrar till att mildra klimatförändringen. Observerade koncentrationer av atmosfäriskt koldioxid uppvisar en stor årlig variabilitet som främst anses vara orsakad av det terrestra ekosystemets respons på klimatföThe terrestrial ecosystem sequesters about one-third of anthropogenic emissions each year, thereby providing a critical ecosystem service that slows the rate of increase of atmospheric carbon dioxide and helps mitigate climate change. Observed atmospheric carbon dioxide concentrations exhibit a large inter-annual variability which is considered to be caused primarily by the response of the terrest
There is a need for research to identify effective implementation strategies for injury prevention training within real-world community sports. The aim of this ecological participatory study was to identify facilitators, among stakeholders at multiple levels, that could help injury prevention training become part of regular training routines in youth team handball. Concept mapping, a mixed-method
The proper alignment of requirements engineering and testing (RET) can be key to software's success. Three practices can provide effective RET alignment: using test cases as requirements, harvesting trace links, and reducing distances between requirements engineers and testers. The Web extra https://youtu.be/M65ZKxfxqME is an audio podcast of author Elizabeth Bjarnason reading the the Requirements
