, : Controlled traffic in sub-tropical grain production. Tillage and traffic in crop production Proceedings of the 11th international conference of the International Soil and Tillage Research Organization, Edinburgh, UK, 11-15 July 1988: 323-327

Tractor and implement energy inputs, crop yields and soil condition were monitored in 2 groups of replicated small plots and 2 large plots over 3 years. Barley was the major winter crop with summer crops of sorghum and soyabeans. The tractor was instrumented to measure fuel flow, drawbar pull, ground speed and wheel slip.

We previously reported that prostate derived Ets transcription factor (PDEF) is a breast tumor-associated molecule. To obtain further insights into PDEF expression in other human tumor types, a cDNA library database from human adult normal and tum...
