The paper explores parental perception of social dangers in the urban environment as a constraint for children to walk and cycle. Group discussions with 37 Swedish and 35 English parents of 7 to 12 year old children revealed that social dangers related to strangers, criminality and drugs concerned parents in both countries. These concerns also influenced travel mode choices for their children’s jo
Measurements of the stopping forces for C-14, N-14 and O-16 ions in Ge and Au, for N-14 and F-19 ions in Ag, as well as for F-19 ions in Au have been made, respectively. A novel technique, reported recently, using PIN diodes coated directly with the stopping medium in a polka dot pattern was used. This provided a set of precise, self-consistent measurements on the same stopping medium. Results sho
The predictive value of distal blood pressure measurements for the level of amputation was studied prospectively in 161 consecutive diabetic patients with foot ulcers. The patients were treated as outpatients except for periods of surgery and when complications requiring hospital care occurred. All patients were treated pre- and postoperatively by the same multidisciplinary foot care team. Either
Planar gamma-scintigraphy is often used to quantify pulmonary deposition patterns from aerosol inhalers. The results are quite different from those obtained using 3-dimensional PET and SPECT. The purpose of this study was to characterize the effects of scatter and tissue attenuation on the distribution of radiolabeled aerosol as measured by planar scintigraphy using Monte Carlo simulations. This s
Let ζ(t), η(t) be continuously differentiable Gaussian processes with mean zero, unit variance, and common covariance function r(t), and such that ζ(t) and η(t) are independent for all t, and consider the movements of a particle with time-varying coordinates (ζ(t), η(t)). The time and location of the exists of the particle across a circle with radius u defines a point process in R3 with its points
Galectin-8 has two different carbohydrate recognition domains (CRDs), the N-terminal Gal-8N and the C-terminal Gal-8C linked by a peptide, and has various effects on cell adhesion and signaling. To understand the mechanism for these effects further, we compared the binding activities of galectin-8 in solution with its binding and activation of cells. We used glycan array analysis to broaden the sp
A combined solid-phase extraction (SPE)-supercritical fluid extraction (SFE) procedure was developed for the analysis of polychlorinated biphenyls (PCBs) in wastewater. The importance of cleaning and drying the filters and SPE-disks prior to eluting PCBs with SFE was studied, leading to improved recoveries for all congeners investigated. The average PCB recovery of the final procedure, at a concen
Objective To estimate the cost-effectiveness of a new treatment (natalizumab) for multiple sclerosis (MS) compared with current standard therapy with disease-modifying drugs (DMDs) in Sweden. Methods A Markov model was constructed to illustrate disease progression based on functional disability (the Expanded Disability Status Scale (EDSS)). The effectiveness of natalizumab was based on a 2-year cl
ObjectiveExamine the factor structure, reliability, and validity of the Pediatric Testing Attitudes Scale-Diabetes (P-TAS-D), a measure of parental attitudes about predictive risk screening for type 1 diabetes in children. MethodsSurveys were completed by 3720 Swedish parents of children participating in the adolescent follow-up of a birth cohort study of type 1 diabetes onset. Parents averaged 43
A search for the pair production of heavy leptons (N-0, L-+/-) predicted by the type-III seesaw theory formulated to explain the origin of small neutrino masses is presented. The decay channels N-0 -> W(+/-)l(+/-) (l = e, mu, tau) and L-+/- -> W(+/-)v (v = v(e), v(mu), v(tau)) are considered. The analysis is performed using the final state that contains two leptons (electrons or muons), two jets f
While the risk for arterial vascular disease has been shown to be influenced by socioeconomic status (SES), there is limited information whether SES also influences the risk for venous thromboembolism (VTE). To evaluate whether there is an association between SES and VTE incidence. In 1990, all 730,050 inhabitants (379,465 women and 350,585 men) above 25 years of age in the County of Skåne in Swed
Introduction: Career termination, an inevitable step in every athlete’s career, has received increased attention within sport psychological research. A career termination that results in psychological problems is of special concern for sport federations, organizations and clubs. Research has shown that it is crucial to consider an athlete’s the reason for career termination. There is evidence that
Paleomagnetic results are presented for two Paleoproterozoic mafic dykes in the Taivalkoski area in northern Karelia Province of the Fennoscandian shield where, based on K-Ar data, the crust has seen minimal effects of the otherwise pervasive 1.8-1.9 Ga Svecofennian orogeny. Within this study a new U-Pb baddeleyite age of 2339 +/- 18 Ma has been determined for one of the E-W trending dykes (dyke A
Revision of the Task Force diagnostic criteria (TFC) for arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) has increased their sensitivity for diagnosis of early and familial forms of the disease. Epsilon wave (EW) is a major diagnostic criterion in the context of ARVC/D, which, however, remains not quantifiable and therefore may leave room for substantial subjective interpretatio
An inclusive search is presented for new physics in events with two isolated leptons (e or mu) having the same electric charge. The data are selected from events collected from p p collisions at root s = 7 TeV by the ATLAS detector and correspond to an integrated luminosity of 34 pb(-1). The spectra in dilepton invariant mass, missing transverse momentum and jet multiplicity are presented and comp
Pregnant women often have questions concerning fetal effects of drugs but reliable information intended for them is limited. This study investigated how pregnant women perceive and value the scientific resource Drugs and Birth Defects (www.janusinfo.se/fosterpaverkan) and compared their opinions to those of health care professionals.
High-quality video is being increasingly delivered over Internet Protocol networks, which means that network operators and service providers need methods to measure the quality of experience (QoE) of the video services. In this paper, we propose a method to speed up the development of no-reference bitstream objective metrics for estimating QoE. This method uses full-reference objective metrics, wh
The current regulations governing production of biofuels in the European Union require that they have to mitigate climate change, by producing > 35% less greenhouse gases (GHG) than fossil fuels. There is a risk that this may not be achievable, since land use for crop production inevitably emits the potent GHG nitrous oxide (N2O), due to nitrogen fertilisation and cycling in the environment. We an
Oxygen-enhanced MRI (OE-MRI) biomarkers have potential value in assessment of COPD, but need further evaluation before treatment-induced changes can be interpreted. The objective was to evaluate how OE-MRI parameters of regional ventilation and oxygen uptake respond to standard pharmacological interventions in COPD, and how the response compares to that of gold standard pulmonary function tests.
