SYNOPSIS An analysis of the 149 cases of haematemesis admitted to Coronation Hospital from January 1951, to September 1959, is presented. The commonest cause was found to be acute gastritis and gastric erosion. These cases were more common in males and usually followed on an alcoholic bout. These were in the main mild. Twenty-five cases associated with peptic ulceration were found, and the lesi...

The present paper describes the analytical solutions for the steady boundary layer flow of a Jeffrey fluid over a shrinking sheet. The governing equations of motions are reduced into a set of nonlinear ordinary differential equations by using similarity transformations. Two types of problems, namely, (1) two-dimensional stagnation flow towards a shrinking sheet and (2) axisymmetric stagnation f...

This paper presents a numerical comparison of two regularizations of the Euler equations, namely, the vortex blob regularization and regularization by physical viscosity. The initial condition is a flat vortex sheet whose vorticity has been smoothed by convolution. The sheet rolls up into a vortex pair. We compute the frequency of oscillations in the core vorticity and scale it using results fo...

Objective This project is investigating the use of carbon nanotubes (CNT) for transparent conducting electrodes in photovoltaic applications. In order to decrease the sheet resistance, both the electronic properties of the CNTs – namely the tube conductivity and tube-to-tube contact resistance – and the sheet morphology have to be controlled. This research aims to reach this target through the ...

OBJECTIVES To investigate the progression of erosions at sites within the carpus, in patients with early rheumatoid arthritis (RA), using magnetic resonance imaging (MRI) and plain radiology over a two year period. METHODS Gadolinium enhanced MRI scans of the dominant wrist were performed in 42 patients with RA at baseline (within six months of symptom onset) and one year. Plain wrist radiogr...
