Objectives. To determine whether physician factors are associated with disease activity status in RA, independently of 28-joint disease activity score (DAS28)-ESR and to re-evaluate DAS28-ESR...
Wave scattering by an array of periodic barriers (2005)
The 2D scattering of a plane harmonic wave obliquely incident on an array of perforated barriers is investigated. The geometry generalises that previously considered and is subject only to the...

Wave Scattering by a Perforated Duct (2002)
Recently, a number of linear wave scattering problems have been studied in the context of embedding formulae. Such formulae typically express the solution for any incident wave angle in terms of the...
Wave Diffraction Through a Perforated Barrier of Non-Zero Thickness (2001)
We consider the diffraction of a prescribed train of monochromatic plane surface water waves by a vertical‐sided, perfectly reflecting thick breakwater standing on a horizontal bed in water of...
NEW SHALLOW FLOWS OVER AN OBSTACLE (1997)
BROAD, A. S., PORTER, D., SEWELL, M. J.
Lowest-order shallow water theory is applied to flow, in a single vertical plane, over a wide class of monotonic mountains. Many new flows are described. These include steady continuous smoothly...
The Edge Effect of a Surface Film on Gravity Waves (1994)
A mathematical model is developed for surface waves which propagate from a region with a clean free surface into a region beneath an inextensible surface film. Matched asymptotic expansions are used...
The re-iterated Galerkin method (1993)
PORTER, D., STIRLING, D. S. G.
The iterated Galerkin method introduced by Sloan is modified to allow the improvement in the Galerkin approximation which iteration produces to be repeated. It is shown in principle, and verified in...
Mycobacterial Infections After Renal Transplantation (1991)
HIGGINS, RM, CAHN, AP, PORTER, D, RICHARDSON, AJ, MITCHELL, RG, HOPKIN, JM, ...
Mycobacterial infections occurred in 11 of 633 (1.7 per cent) recipients of successful renal transplants. There were no cases of tuberculosis in patients receiving chemoprophylaxis, but amongst those...
The Numerical Determination of Fundamental Solutions of Elliptic Equations (1986)
A method is developed for the numerical determination of the fundamental solution of a second-order, elliptic partial differential equation. It is shown that existing formulations based on...
The Edge Effect of a Surface Film on Gravity Waves (1974)
A mathematical model is developed for surface waves which propagate from a region with a clean free surface into a region beneath an inextensible surface film. Matched asymptotic expansions are used...
