Numerical solutions are presented for the two-dimensional flow past a circular cylinder in an infinite domain. The flow is assumed to be uniform at infinity and the cylinder is allowed to rotate with a constant angular velocity omega. Omega is chosen to be in the range (0 - 5W/a) where a is the radius of the cylinder and W is the mainstream velocity at infinity. To incorporate visco-elastic properties into the flow, and implicit four constant Oldroyd model is used, and the resulting nonlinear constitutive equations are solved in parallel with the equations of motion as a coupled set of partial differential equations. The method of solution used is a finite difference technique with block over-relaxation. The results are compared with those of other numerical computations as well as with available experimental data. In particular, consideration is given to the influence of cylinder rotation and of visco-elasticity on the drag and lift experienced by the cylinder and on the streamline patterns and vorticity distribution.

"The first Millennium Development Goal - to halve world poverty by 2015 - has become an unlikely prospect. The reasons lie in the present form of the globalisation of the market, together with continuing preference shown to neo-liberal economic and social policies. If poverty is to be systematically reduced the orthodoxies of definition, measurement, explanation and resolution, which as key elements of the problem necessarily reinforce each other, have to be re-examined and re-formulated quickly"--Abstract.

Two apprentice photographers, David Taylor and John Evans, find themselves unemployed and desperate for work when their employer dies. They fall into the clutches of Hood, a notorious charlatan, who is eager to exploit them as "spirit photographers" with the aid of the infamous Tate Camera now owned by David. This notorious camera is said to have the ability not only to photograph spirits, but it can predict how and when the person photographed will die.

In this report we have used models of seabed sediment mobilisation to examine IDH [intermediate disturbance hypothesis] for Australia''s continental shelf environment. Although other disturbance processes may occur (eg. biological, temperature, salinity, anthropogenic, etc.) our study addresses only the physical disturbance of the seabed by waves and currents. Our study has shown that it is feasible to model the frequency and magnitude of seabed disturbance in relation to the dominant energy source (wave-dominated shelf, tide-dominated shelf or tropical cyclone dominated shelf). In this report we have used models of seabed sediment mobilisation to examine IDH for Australia''s continental shelf environment. --Executive summary.
