Desert locust plagues can affect up to 20 per cent of the surface of the Earth. Data on locust breeding, environmental conditions and swarm movements in affected countries, are collected at the headquarters of the U.N. Food and Agriculture Organization in Rome. GIs technology coupled with remote sensing inputs allows these data to be utilised for monitoring and forecasting purposes much more effectively than heretofore. Design requirements and the implementation strategy for such a GIS are examined, emphasizing the role of global digital map datasets such as the Digital Chart of the World, the importance of effective data integration and the need for an ergonomic user interface that facilitates both data capture and analysis.

This paper presents the results of adding the antibiotic cefuroxime to CMW bone cement in a group of patients undergoing total hip or knee replacement, in which the levels of cefuroxime were assayed in the blood, wound drainage fluid, urine and surplus bone cement. It was found that very small amounts of cefuroxime, less than 5%, were recovered in the urine, serum and drainage fluid in the first week following operation, and since it is known that cefuroxime is not metabolised or excreted elsewhere in the body, it must follow that approximately 95% remains in the bone cement as a potential source of prophylaxis against infection.
