There is increasing evidence that fibre size and shape play an important part in the production of health effects related to asbestos. The dimensions of airborne fibres collected at various stages of fibre processing in three mines and six mills producing three types of asbestos were measured using phase contrast light microscopy and transmission electron microscopy. Airborne fibres of differen...

In 2001, the Meeting of the COMESA Ministers of Agriculture raised concerns that proliferation of genetically modified organisms (GMOs) could impact significantly on trade and food security in the region. This triggered studies on a regional approach to biotechnology and biosafety policy in Eastern and Southern Africa. The studies and stakeholder consultations revealed that farm incomes would i...

SUMMARY Corn, soybean, and sunflower hybrids with improved agronomic and nutritional traits are grown widely today. Barring increased concern about genetically altered crops, production of specialty grains is likely to increase because novel traits possessed by many new hybrids are desired by both grain producers and grain users. Most specialty grains available today possess improved altered " ...
