Background: Familial confounding is confounding due to genetics or environmental exposures shared by family members. We aimed to study whether familial confounding explains the association between body mass index (BMI) and severe hip osteoarthritis (OA). Methods: We linked data from the Norwegian Arthroplasty Registry with the Norwegian Twin Registry on the National ID-number in 2014, generating a

Aluminium is one of the most abundant metals in the earth’s crust, and aluminium compounds are widely used. Aluminium is considered to be a weak allergen, but contact allergy to aluminium has been more frequently reported in recent years. The most important routes of sensitization to aluminium are aluminium-containing vaccines, hyposensitization with aluminium-adsorbed extracts and contact with al

Gold is today a well-known but still controversial contact sensitizer. The patch test reaction to gold is sometimes difficult to read, and positive reactions typically appear late; therefore, two readings are of utmost importance. Gold is not generally within the baseline series but is recommended in any dental and metal series. Gold can give rise not only to local eczematous reactions, chronic pa

Percutaneous coronary interventions and stenting have existed since the 1970s. Stents can be made of different materials and have different designs. A complication to the intervention and especially to bare metal stents is in-stent restenosis with neointimal proliferation and chronic inflammation, which has several causes briefly discussed below. A possible association between stents and metal all

Objective: To describe the design and rationale for the genetic analysis of acute and chronic cerebrovascular neuroimaging phenotypes detected on clinical MRI in patients with acute ischemic stroke (AIS) within the scope of the MRI-GENetics Interface Exploration (MRI-GENIE) study. Methods: MRI-GENIE capitalizes on the existing infrastructure of the Stroke Genetics Network (SiGN). In total, 12 inte

ExtendJ (formerly JastAddJ) is an extensible Java compiler, supporting full Java source-to-bytecode compilation. ExtendJ enables researchers and developers to easily build powerful language extensions, custom static analyses, and other tools for Java. ExtendJ is built with Reference Attribute Grammars and Aspect Oriented Programming, enabling easy extension development.

Turbulent flame speeds have been measured in a single cylinder S.I. engine and in a stationary atmospheric burner. One- and two-point LDA has been used to measure turbulence intensities and integral length scales. Stretching, in terms of Karlovitz numbers could be estimated from these measurements. The influence of moving average filtered turbulence on the flame speed in the S.I. engine is in agre

Based on a review of recent developments in Sweden and Finland, this chapter analyzes the roles of public organizations in the governance of a transition to Mobility-as-a-Service (MaaS). In particular, we draw on insights from transition frameworks to explore what these two pioneering cases can teach us about how the public sector can both enable the development of MaaS and steer the development t

A 59-year-old female secretary was referred for evaluation and treatment of a non-healing painful ulcer on the medial aspect of her right lower leg. The ulcer had been recurrent almost every year for the past 9 years, often healing during the winter season. She had since early childhood been overweight (currently 87 kg, 170 cm, body mass index 30) and had difficulty in using compression stocking.

EU-funding opportunities create incentives for local governments to partake in the implementation of EU regional policies; yet there is a lack of knowledge on the local effects in everyday municipal work. In this article we examine how the European Social Fund (ESF) is used by the EU and national level to govern local activities, how the subnational level acts in response to this and with what con

Objective: Shared genetic background may explain phenotypic associations between depression and Type 2 diabetes (T2D). We aimed to study, on a genome-wide level, if genetic correlation and pleiotropic loci exist between depressive symptoms and T2D or glycemic traits. Methods: We estimated single-nucleotide polymorphism (SNP)-based heritability and analyzed genetic correlation between depressive sy

We report new time-resolved laser-induced fluorescence lifetime measurements for 22 highly excited even-parity levels in singly ionized yttrium (Y II). To populate these levels belonging to the configurations 4d6s, 5s6s 4d5d, 5p2, 4d7s and 4d6d, a two-step laser excitation technique was used. Our previous pseudo-relativistic Hartree-Fock model (Biémont et al. 2011) was improved by extending the co

Continuously operated settling tanks are used for the gravity separation of solid-liquid suspensions in several industries. Mathematical models of these units form a topic for well-posedness and numerical analysis even in one space dimension due to the spatially discontinuous coefficients of the underlying strongly degenerate parabolic, nonlinear model partial differential equation (PDE). Such a m

Background—The effects of ticagrelor pretreatment in patients with ST-segment–elevation myocardial infarction undergoing primary percutaneous coronary intervention (PCI) is debated. This study investigated the effects of ticagrelor pretreatment on clinical outcomes in this patient group. Methods and Results—Patients with ST-segment–elevation myocardial infarction undergoing primary PCI were includ

Due to their unique optical properties, III-V nanowires are promising candidates for the development of efficient solar cells, LEDs and nanoscaled lasers. The interaction of nanowires with fluorescent molecules is also of interest, as these nanostructures can act as nanoscaled optical fibers. The light emitted by a fluorophore close to a nanowire surface can in fact couple into the supported waveg

A search is presented for the direct pair production of the stop, the supersymmetric partner of the top quark, that decays through an R-parity-violating coupling to a final state with two leptons and two jets, at least one of which is identified as a b-jet. The data set corresponds to an integrated luminosity of 36.1 fb-1 of proton-proton collisions at a center-of-mass energy of √s= 13 TeV, collec
