The design and testing of traps are described for control of the buffalo fly Haematobia irritans exigua on dairy and beef cattle in Australia. The initial design, for use on milking cows, consisted of a translucent, plastic-covered tunnel, with compartments separated by plastic partitions and doorways with black shade-cloth curtains. The curtains brushed flies off the cattle as they passed through the tunnel. The flies were attracted to the light and ascended the walls to be confined in the dome-shaped roof. The traps removed 80% of the flies each time the cattle passed through them. During farm trials in 1990-91, fly numbers (8) on milking cows were reduced by 85% compared with those (94) on other cattle on the same farm, and by 65% compared with neighbouring milking cows (30), which received an average of three pesticide treatments. Breeding of buffalo fly was reduced by 81% on the pastures grazed by milking cattle using the traps. In 1992 and 1993, a smaller portable trap was developed for use by all types of cattle. Replacement of the shade-cloth curtains with brushes and addition of a translucent false ceiling increased the efficiency of the trap from 80 to 90%. The traps achieved 90% control on five dairy and two beef properties compared with cattle given traditional pesticide treatments. The results demonstrate the feasibility of controlling Haematobia without insecticides, by using a simple, sustainable and environmentally friendly trap, provided that cattle use the traps regularly.

Sprayed concrete is widely applied thanks to current development of road and underground building industry. Selection of input materials, design, preparation and testing of sprayed concrete is relatively expensive because spraying machinery has to be used for application. The paper focuses on possibilities of manufacture and testing of sprayed concrete prepared in common laboratory mixer and compacted by vibration combined with defined level of pressure. This approach seems to be an alternative for initial design and testing of sprayed concrete prepared by machinery equipment.

The increased availability of High Performance Computing and Communications (HPCC) offers scientists and students the potential for effective remote interactive use of centralized, specialized, and expensive instrumentation and computers. Examples of instruments capable of remote operation that may be usefully controlled from a distance are increasing. Some in current use include telescopes, networks of remote geophysical sensing devices and more recently, the intermediate high voltage electron microscope developed at the San Diego Microscopy and Imaging Resource (SDMIR) in La Jolla. In this presentation the imaging capabilities of a specially designed JEOL 4000EX IVEM will be described. This instrument was developed mainly to facilitate the extraction of 3-dimensional information from thick sections. In addition, progress will be described on a project now underway to develop a more advanced version of the Telemicroscopy software we previously demonstrated as a tool to for providing remote access to this IVEM (Mercurio et al., 1992; Fan et al., 1992).
