A note on oblique water entry
No full textAn apparently minor error in Howison, Ockendon & Oliver (J. Eng. Math. 48:321–337, 2004) obscured the fact that the points at which the free surface turns over in the solution of the Wagner model for the oblique impact of a two-dimensional body are directly related to the turnover points in the equivalent normal impact problem. This note corrects some results given in Howison, Ockendon & Oliver (2004) and discusses the implications for the applicability of the Wagner\ud
model

High diagnostic yield of tuberculosis from screening urine samples from HIV-infected patients with advanced immunodeficiency using the Xpert MTB/RIF assay.
No full text: ABSTRACT:: We determined the diagnostic yield of the Xpert MTB/RIF assay for tuberculosis (TB) when testing small volumes of urine from ambulatory HIV-infected patients prior to starting antiretroviral therapy (ART) in South Africa. Compared to a gold standard of sputum culture, the sensitivity of urine Xpert among those with CD4 cell counts of <50, 50-100 and >100 cells/?L were 44.4%, 25.0% and 2.7% (P=0.001), respectively. Urine Xpert testing provides a means of rapid TB diagnosis in patients with advanced immunodeficiency and poor prognosis. These data are indicative of high rates of TB dissemination and renal involvement in this clinical population

A note on the two-phase Hele-Shaw problem
No full textWe discuss some techniques for finding explicit solutions to immiscible two-phase flow in a Hele-Shaw cell, exploiting properties of the Schwartz function of the interface between the fluids. We also discuss the question of the well-posedness of this problem
Free and moving boundary problems in hydrodynamics.
No full textDiscusses well posed and ill posed problems in free surface flows in porous media (with or without gravity) and the two dimensional Hele Shaw cell analogue. Examines models for these flows, related heat and mass transfer problems, and studies local stability analyses. Establishes well posedness criteria. Discusses the rectangular dam problem and considers exact and approximate methods of solution. Develops an asymptotic approximation for cases where change in fluid level is small compared to overall dam dimensions. Derives explicit solutions from a linear formulation, and also treats the problem as a variational inequality. Studies Hele Shaw flow without gravity and presents a class of explicit solutions for unsteady flow. These solutions break down in finite time. Examines surface tension effects and proposes a numerical method for ill posed Hele Shaw flow. Presents numerical results. (C.J.U.

Droplet impact on a thin fluid layer
No full textThe initial stages of high-velocity droplet impact on a shallow water layer are described, with special emphasis given to the spray jet mechanics. Four stages of impact are delineated, with appropriate scalings, and the successively more important influence of the base is analysed. In particular, there is a finite time before which part of the water in the layer remains under the droplet and after which all of the layer is ejected in the splash jet
