Physical impairments in longstanding hip and groin pain : Cross-sectional comparison of patients with hip-related pain or non-hip-related groin pain and healthy controls
Objectives: To compare physical impairments between patients with hip-related pain and those with non-hip-related groin pain, and to compare both patient groups with healthy controls. Design: Cross-sectional. Participants: Eighty-one hip and groin pain patients were consecutively included and categorized into having hip-related pain or non-hip-related groin pain. Twenty-eight healthy controls were
Compensating for a stressful pregnancy? Glucocorticoid treatment during gravidity reduces metabolic rate in female fence lizards post-parturition
Reproduction is a critical part of an animal's life history, but one which incurs significant costs to survival and future reproductive potential. These physiological consequences are likely to be influenced by context – for example, if an individual is subject to environmental stressors, physiological and behavioral changes associated with reproduction may be altered. Glucocorticoids, hormones pr
Non-linear transverse dynamics for storage rings with applications to the low-energy antiproton ring (LEAR) at CERN
Blood culture time to positivity in non-β-hemolytic streptococcal bacteremia as a predictor of infective endocarditis-a retrospective cohort study
Non-β-hemolytic streptococci (NBHS) cause infective endocarditis (IE) and a short blood culture time to positivity (TTP) is associated with risk of IE in bacteremia with other pathogens. In this retrospective population-based cohort study, we investigate if TTP is associated to IE or mortality. Of 263 episodes with NBHS bacteremia, 28 represented IE and the median TTP did not differ significantly
Ombordmätningar av partiklar och koldioxid i X60B förarhytter
SyfteMålsättningen med denna studie var dels att säkerställa att tågpersonalen inte utsätts för höga halter av partiklar i sitt arbete på X60B fordon som trafikerar Arlanda. Syftet var även att ta fram ett förhållande mellan partikelnivåerna i tunnelmiljö och ombord på pendeltågsfordon av typ X60B i förarhytterna för att avgöra ventilationsfiltrets kapacitet. Kunskapen om filtreringseffektiviteten
Ranking of conventional and novel disc brake materials with respect to airborne particle emissions
PM10 from the wear of disc brakes could contribute up to 50 % of the total non-exhaust emissions from road transport in EU. The wear originates from the contact surfaces of the friction material and the disc. One possible way of decreasing the PM10 emissions is to change the materials of the contact pair in terms of composition and coatings. Therefore the particle emissions of three novel friction
Eco Design of Brake Pads with Recycled Friction Materials
Recycling of brake pads is a tough but promising work considering the current end of lifecycle. This study assesses the environmental performance of brake pads made up of recycled friction materials in terms of energy use, CO2 footprint and airborne particle number. Energy use and CO2 footprint are calculated with the data from CES Edupack and airborne emission particle number is measured on a pin
Utsådda blommor räddar inte insekterna
Om vi vill rädda hotade insektsarter är det miljöer med traditionella ängsväxter som vi behöver mer av, inte fröblandningar av oklart ursprung från handeln. Det skriver flera debattörer.
Revisiting Optical Reflectance from Au(111) Electrode Surfaces with Combined High-Energy Surface X-ray Diffraction
We have combined high-energy surface X-ray diffraction (HESXRD) with 2D surface optical reflectance (2D-SOR) to perform in situ electrochemical measurements of a Au(111) electrode in 0.1 M HClO4 electrolyte. We show that electrochemically induced changes to Au(111) surface during cyclic voltammetry can be simultaneously observed with 2D-SOR and HESXRD. We discuss how small one atom high 1x1 island
The contributions of public health policies and healthcare quality to gender gap and country differences in life expectancy in the UK
Background: In many high-income countries, life expectancy (LE) has increased, with women outliving men. This gender gap in LE (GGLE) has been explained with biological factors, healthy behaviours, health status, and sociodemographic characteristics, but little attention has been paid to the role of public health policies that include/affect these factors. This study aimed to assess the contributi

Vilda bin i Skåne
Länsstyrelsen Skåne har släppt en ny rapport med de senaste vetenskapliga rönen om vilda bin i Skåne. Rapporten är en sammanställning om vilda bin och är ett led i Länsstyrelsens arbete med regeringsuppdraget att gynna vilda pollinatörer.Rapporten kan användas som underlag för att arbeta vidare med åtgärder för att gynna Skånes pollinatörer, något som är extra viktigt i Skåne eftersom runt 75 proc
Mutual surveillance on Airbnb
Digital technology affords new means of controlling and managing. The platform economy relies on complex surveillance techniques to analyze, control, and manipulate on the basis of reviews, evaluations, and other volunteered data. This paper conceptualizes mechanisms of surveillance, with a focus on Airbnb. It sets out with a discussion of trust and reputation-building to then analyze the mechanis

The SWEDEHEART secondary prevention and cardiac rehabilitation registry (SWEDEHEART CR registry)
Aims: The quality registry SWEDEHEART covers data across the patient pathway after an acute myocardial infarction (MI), from hospital care to secondary prevention. Although cardiac rehabilitation (CR) is strongly recommended after an MI, there is still heterogeneity regarding standards, uptake, and adherence rates. The aim of the SWEDEHEART-CR registry is to provide continuous information on secon

Syncope : new solutions for an old problem
Syncope is a frequent event in the general population. Approximately 1%-2% of all emergency department admissions are due to syncope and at least one third of all people experience fainting in their life. Although consequences of cardiac syncope are generally feared, non-cardiac syncope is much more common and may be associated with severe injuries and quality of life impairment, particularly in o
Photodissociation dynamics of halogenated aromatic molecules : The case of core-ionized tetrabromothiophene
We studied the gas-phase photodissociation of a fully halogenated aromatic molecule, tetrabromothiophene, upon core-shell ionization by using synchrotron radiation and energy-resolved multiparticle coincidence spectroscopy. Photodynamics was initiated by the selective soft X-ray ionization of three elements-C, S, and Br-leading to the formation of dicationic states by Auger decay. From a detailed
