Turbulent states in plane Couette flow with rotation
No full textShearing and rotational forces in fluids can significantly alter the transport of momentum. A numerical investigation was undertaken to study the role of these forces using plane Couette flow subject to rotation about an axis perpendicular to both wall-normal and streamwise directions. Using a set of progressively higher Reynolds numbers up to Re = 5200, we find that the momentum flux, measured by the wall shear stress, for a given Re is a non-monotonic function of rotation number, Ro. For low-to-moderate Reynolds numbers, we find a maximum that is associated with flow fields that are dominated by downstream vortices and calculations of 2D vortices capture the maximum also quantitatively. For higher Reynolds numbers, a second stronger maximum emerges at smaller rotation numbers, closer to non-rotating plane Couette flow. It is carried by flows with a markedly 3D structure and cannot be captured by 2D vortex studies. As the Reynolds number increases, this maximum becomes stronger and eventually overtakes the one associated with the 2D flow state.Process and EnergyMechanical, Maritime and Materials Engineerin
How effective is a short CSM-based online intervention on intended flu prevention behaviour?
No full textThis is the PowerPoint presentation for the oral presentation of the paper "How effective is a short CSM-based online intervention on intended flu prevention behaviour?" in 2017 at the 31st Conference of the European Health Psychology Society (EHPS) in Padua, Italy.Background: Influenza is a serious infectious disease that can be prevented by active behaviours (e.g., handwashing), avoidant behaviours (e.g., no handshaking), and getting a flu shot. Based on the assumptions of the Common Sense Model of self-regulation, an online intervention targeting illness representations about influenza (i.e., emotional representations, coherence, consequences, and prevention control) was designed to increase the intention to conduct preventive behaviours. It was hypothesized that positive effects of the intervention on preventive behaviours would result from changes in illness perceptions.Method: This online study had a randomized pre- posttest control group design; 416 participants (72% female, mean age 37 years) took part. Before and after the intervention, illness perceptions about influenza and the intention to conduct preventive behaviours were measured. Data were analysed by 2x2 ANOVAs and mediation analyses.Findings: The ANOVAs showed that the intervention increased the perception of negative consequences and prevention control (but not emotional representations and coherence) as well as the intention to conduct preventive behaviours. Mediation analyses revealed that the increase in perceived consequences and/or prevention control partially mediated the effect of the intervention on the increase of the intention for active (indirect effects: .03*, .10*) and avoidant preventive behaviour (indirect effects: .01ns, .05*), but not for getting a flu shot (indirect effects: .02ns, .04ns). Discussion: The intervention proved to be successful in changing illness perceptions and increasing the intention to conduct preventive behaviours. The findings provide evidence for the usefulness of the CSM in the context of disease prevention and health promotion.Citation: Salewski, C., Trusch, B., & Vollmann, M. (2017).

No full textMeasuring fast ions in fusion plasmas with neutron diagnostics at JET
No full textFast ions in fusion plasmas often leave characteristic signatures in the neutron emission from the plasma. In this paper, we show how neutron measurements can be used to study fast ions and give examples of physics results obtained on present day tokamaks. The focus is on measurements with dedicated neutron spectrometers and with compact neutron detectors used in each channel of neutron profile monitors. A measured neutron spectrum can be analyzed in several different ways, depending on the physics scenario under consideration. Gross features of a fast ion energy distribution can be studied by applying suitably chosen thresholds to the measured spectrum, thus probing ions with different energies. With this technique it is possible to study the interaction between fast ions and MHD activity, such as toroidal Alfvén eigenmodes (TAEs) and sawtooth instabilities. Quantitative comparisons with modeling can be performed by a direct computation of the neutron emission expected from a given fast ion distribution. Within this framework it is also possible to determine physics parameters, such as the supra-thermal fraction of the neutron emission, by fitting model parameters to the data. A detailed, model-independent estimate of the fast ion distribution can be obtained by analyzing the data in terms of velocity space weight functions. Using this method, fast ion distributions can be resolved in both energy and pitch by combining neutron and gamma-ray measurements obtained along several different sightlines. Fast ion measurements of the type described in this paper will also be possible at ITER, provided that the spectrometers have the dynamic range required to resolve the fast ion spectral features in the presence of the dominating thermonuclear neutron emission. A dedicated high-resolution neutron spectrometer has been designed for this purpose
