Interaction between turbulence and flame in an S.I. engine and in a stationary burner

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

Governing Mobility-as-a-Service : Insights from Sweden and Finland: Towards New Organizational Structures for the Development of Shared, Automated, Electric and Integrated Mobility

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

Venous ulcers associated with superficial venous insufficiency

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.

Styrning genom frivillig koordinering? En studie av europeiska socialfondens genomförande i lokal förvaltning

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

Bivariate genome-wide association study of depressive symptoms with type 2 diabetes and quantitative glycemic traits

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

Lifetime measurements using two-step laser excitation for high-lying even-parity levels and improved theoretical oscillator strengths in Y II

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

A difference scheme for a degenerating convection-diffusion-reaction system modelling continuous sedimentation

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

No benefit of ticagrelor pretreatment compared with treatment during percutaneous coronary intervention in patients with ST-segment⇓elevation myocardial infarction undergoing primary percutaneous coronary intervention

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

Lightguiding of Fluorescence in Nanowires : Principles, Optimization and Implementation for Biosensing

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

Search for B - L R-parity-violating top squarks in √s=13 TeV pp collisions with the ATLAS experiment

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

Neuroblastoma with flat genomic profile : A question of representativity?

Neuroblastoma is one of the most common paediatric malignancies. Detection of somatic genetic alterations in this tumour is instrumental for its risk stratification and treatment. On the other hand, an absence of detected chromosomal imbalances in neuroblastoma biopsies is difficult to interpret because it is unclear whether this situation truly reflects the tumour genome or if it is due to subopt
