The quality assurance provided by preimplantation biopsy quantification of chronic damage may allow greater use of kidneys from expanded criteria donors, and thereby expand the deceased donor pool. Preimplantation biopsy may, however, identify additi

An impulse-based model is developed to represent a coupling between turbulent flow in the atmosphere and turbulent flow in the ocean. In particular, it is argued that the atmosphere flowing horizontally over the ocean surface generates a velocity flu

We describe a numerical model of near-wall flow in R 2 which is based on the kinematics of sheet elements of impulse. This model is developed from Kuz’min’s [Phys. Lett. A 96 (1983) 88–90] decomposition of the velocity field, which we interpret

The “pulvinar sign” on MRI brain scan is defined as hyperintensity of the posterior thalamus relative to the signal intensity of the anterior putamen.1 In the appropriate clinical context, the pulvinar sign and hyperintensity in the dorsomedial t

In Part I of this paper (Summers and Roberts, J. Turbul, 10(2) (2009)), a particle model of homogeneous turbulence was introduced – a model which is based on a self-similarity in the kinematics inherent to a scale hierarchy of interacting particles

This paper looks at the relationship between wind flow round a building and heat loss from it. The relative merits of numerical and wind tunnel models are discussed and various numerical techniques examined.

In an attempt to test a computer simulation of wind flow around a block-shaped building against corresponding flows observed in a boundary-layer wind-tunnel, numerical solutions to the steady-state Navier-Stokes equations are compared with the three

Chorin (J. Comput. Phys.27, 428 (1978)) applied a random vortex sheet method to the problem of incompressible boundary-layer flow with a uniform external velocity, U(x) = U0. The application of the method is here extended to the case of an external f

The steady Navier–Stokes equation is solved to simulate the wind-flow environment of three-dimensional configurations of buildings. The method assumes an incident wind described by a power-law velocity profile. A new method for controlling the two-
