Combination of a leadless pacemaker and subcutaneous defibrillator with nine effective shock treatments during follow-up of 18 months
We present a case of combination of a leadless pacemaker (Micra) and a subcutaneous implantable cardioverter-defibrillator (S-ICD). The patient had a total of nine adequate shock treatments of ventricular fibrillation during 18 months of follow-up after the implantation. The shock treatments did not lead to any alteration in the Micra. All three sensing vectors of the S-ICD worked well. After 18 m
Moderators of outcome in a web-based substance use intervention for adolescents.
Aims: In this article we explore the moderators of effectiveness of WISEteens (Web-based brief Intervention for SubstancE using teens), a fully automated web-based brief motivational intervention targeting risky substance use among adolescents. Based on previous studies, we examined the differential effects on drinking of sex, readiness to change, self-efficacy, alcohol risk status, and parental m

T-matrix method for closely adjacent obstacles
This paper presents a novel method to calculate the T-matrix for two non-spherical obstacles positioned close to each other, where the individual circumscribed spheres intersect. This is achieved by translating the obstacles coordinate systems, using translation matrices for spherical vector waves. The new circumscribing spheres enables the obstacles to be positioned close to each other. A new tot

Indoor air temperatures, CO2 concentrations and ventilation rates : Long-term measurements in newly built low-energy schools in Sweden
Within a period of ten years a large number of schools need to be built in Sweden and these new schools need to be nearly zero energy buildings. School classrooms are required to provide healthy learning environments to help children perceive and process information. This means that classrooms must provide adequate levels of indoor air quality and thermal comfort. This article investigates CO2 con

Pregnant smokers: Potential for improvement of intervention
Background In many countries, smoking is considered as the most important preventable risk factor for a complicated pregnancy and delivery. However in Denmark, there is no clear picture of pregnant women. The aim was therefore to examine the prevalence, characteristics and registration of maternal smoking and quitting during pregnancy as well as estimate the potential for improvement.Methods This

Finite element analysis of some problems in connection with intergranular stress corrosion cracking
Elasto plastic analysis was performed to determine the conditions at the root of a notch in a CERT specimen and the conditions at a crack growing in a CERT specimen. Furthermore. analysis of growth under small scale yielding was performed in order to facilitate analysis of compact tension specimen. By experiments it was shown how the stress strain conditions affect initiation of intergranular crac
Detection of circulating tumor cells and circulating tumor DNA before and after mammographic breast compression in a cohort of breast cancer patients scheduled for neoadjuvant treatment
PurposeIt is not known if mammographic breast compression of a primary tumor causes shedding of tumor cells into the circulatory system. Little is known about how the detection of circulating biomarkers such as circulating tumor cells (CTCs) or circulating tumor DNA (ctDNA) is affected by breast compression intervention.MethodsCTCs and ctDNA were analyzed in blood samples collected before and afte
A comparative study of two steady-state situations at a quasi-statistically growing crack in a steinless steel.
Evolution of averaged local premixed flame thickness in a turbulent flow
In the combustion literature, contradictory results on the influence of turbulence on the local thickness of a premixed flame can be found and the present paper aims at contributing to reconcile this issue. First, different measures of local flame thickness in a turbulent flow, e.g. area-weighted and unweighted surface-averaged values of (i) |∇c|, i.e., the absolute value of 3D gradient of the com
Sjuttiofem år efter Nils Hylander : nytt ljus över engelska landskapsparker och deras flora i Sverige
During World War II, Nils Hylander worked on his monumental theses about the wood lawn neophytes [German: Grassameneinkömmlinge] of Swedish parks. Most probably, the original aim was to date and locate the sources of the imported seed that had obviously been widely used in the 1800’s for establishing lawns in parks of the English style, but due to restrictions to work and travel during the war, Hy
A review of assessment methods for the urban environment and its energy sustainability to guarantee climate adaptation of future cities
The current climate change is calling for a drastic reduction of energy demand as well as of greenhouse gases. Besides this, cities also need to adapt to face the challenges related to climate change. Cities, with their complex urban texture and fabric, can be represented as a diverse ecosystem that does not have a clear and defined boundary. Multiple software tools that have been developed, in re
