Investigation of the impact of fur seals on the conversation status of seabirds at islands off South Africa and the the Prince Edward Islands by Makhado, Azwianewi Benedict

“…Most adult African penguins were killed as they returned in the evening from foraging at sea. Wind speed and direction, sea state and tide had a variable and lesser influence on predation rates. …”

Development of a constant-volume combustion apparatus for fuels research by Miller, Geoff

“…The pressure and temperature at injection were to be independently variable. Following a literature survey into previous fuels research work and the associated equipment used, such as rapid compression machines and continuous flow combustion chambers, the decision was made to develop a constant volume combustion chamber (CVCC). …”

Design and implementation of a high strain Town rate biaxial tension test for elastomeric materials and biological soft tissue by Graham, Aaron

“…Higher strain rates of up to 2500s −1 are achieved, but are poorly measured due to equipment limitations of the high speed cameras used. The strain rates achieved had some variability, but were significantly more consistent than those achieved by high rate biaxial tension tests found in the literature. …”

Resolving cross-shelf dynamics in the Agulhas Current from GlobCurrent and glider observations by Maja, Tumelo

“…GlobCurrent also exhibits, at times, directional errors in addition to the current speed discrepancies. This research study demonstrates the limitation of the GlobCurrent product for monitoring ocean current variability in shallow, coastal waters and regions dominated by small mesoscale variability. …”
