The effect of sudden source buoyancy flux increases on turbulent plumes

Building upon the recent experimentally verified modelling of turbulent plumes which are subject to decreases in their source strength (Scase et al., J. Fluid Mech., vol. 563, 2006b, p. 443), we consider the complementary case where the plume's source strength is increased. We consider the effect of increasing the source strength of an established plume and we also compare time-dependent plume model predictions for the behaviour of a starting plume to those of Turner (J. Fluid Mech., vol. 13, 1962, p. 356)

Shaping the future assistant/associate practitioner workforce; a Hampshire case study

This case study looks at the two-year full-time-equivalent Foundation Degree in Health and Social Care, initially developed in partnership between University Hospital Southampton NHS Foundation Trust and Southampton Solent University, Hampshire, UK. The aim of this collaborative initiative is to develop healthcare support workers to gain and apply the required knowledge, skills, values and behaviours to care for patients/families/other service users and relatives in complex clinical situations, within the emerging role descriptors of an Assistant/Associate Practitioner (AP), often within a specialist/specified context. Since the initial cohort of students began in January 2012, the foundation degree now has over 100 students/healthcare support workers across the two years and is being delivered in partnership with an increasing number of NHS trusts. This paper will discuss the innovative and unique features of this foundation degree in health and social care, including the collaborative model of its curriculum design, delivery and management

Video recording true single-photon double-slit interference

As normally used, no commercially available camera has a low-enough dark noise to directly produce video recordings of double-slit interference at the photon-by-photon level, because readout noise significantly contaminates or overwhelms the signal. In this work, noise levels are significantly reduced by turning on the camera only when the presence of a photon has been heralded by the arrival, at an independent detector, of a time-correlated photon produced via parametric down-conversion. This triggering scheme provides the improvement required for direct video imaging of Young's double-slit experiment with single photons, allowing clarified versions of this foundational demonstration. Further, we introduce variations on this experiment aimed at promoting discussion of the role spatial coherence plays in such a measurement. We also emphasize complementary aspects of single-photon measurement, where imaging yields (transverse) position information, while diffraction yields the transverse momentum, and highlight the roles of transverse position and momentum correlations between down-converted photons, including examples of "ghost" imaging and diffraction.
