In the presence of pure oxygen at one atmosphere pressure Micromonospora vulgaris is unable to form in liquid media a surface pellicle of growth-bearing aerial mycelium. The production of bottom growth is either unaffected or stimulated by oxygen. Vegetative mycelium which develops from spores in Warburg vessels has an oxygen uptake that is similar in the presence of air or oxygen. Aerial mycel...

Assessments were made of the influence of several microclimatic variables on the availability of third-stage larvae of Ostertagia ostertagi, on pasture herbage. Variables most closely related to recovery of larvae from the lower herbage samples were: maximum air, mat and dung temperatures. Recovery of larvae from the upper portion of the herbage was closely correlated with dung temperature, sam...

Flywheel systems based on fibre composites can have power densities which are significantly better than for electrochemical batteries. Hence, they have considerable potential for use as peak power buffers in drive-trains for electric and hybrid vehicles. As the rotational speed is increased, however, bearing friction power loss and iron losses in the motor/generator become more significant. Thu...

Air-bearing-based spacecraft simulators are widely used to develop and verify spacecraft control techniques required by modern spacecraft applications. To create a spacelike environment with ground spacecraft simulators, the effects of gravity should be minimized. For a spherical air-bearing system with 3 rotational degrees of freedom, the center of rotation of the spacecraft simulator should b...
