The "success story" of peasant tobacco production in Tanzania : the political economy of a commodity producing peasantry
- 1979
-
Reports (other academic/artistic)abstract
- This book studies how Tanzania in a period of 25-30 years became a tobacco producer and exporter. But its emphasis is on production, and therefore on the producers. It analyses the processes that made Tanzanians into peasant producers of tobacco for the international market. The dynamics of the organization of production under changing conditions of production. The effects on the development of productive forces, reproduction processes and the standard of living among the producers.

Elemental Abundance Variation with Particle Size in Aerosols from Welding Operations
- 1974

Conference paper (peer-reviewed)abstract
- The effect of airborne particulate matter on human health is today of considerable research interest. Essential parameters include elemental composition sampling with low pressure cascade impactors and analysis by particle induced x-ray emission spectroscopy (PIXE). It is shown that the aerosol generated by arc welding operations is several orders of magnitude denser than aerosols in ambient air. Most of the mass is found on particles between 0.1 and 1µm diameter, but the size distribution differs from one welding technique to another. The relative composition of the aerosol is found to differ significantly from that of both the welding piece and the electrode indicating the presence of fractionation of the type indicated in this work in designing electrodes and welding pieces to minimize the health hazards associated with the welding.
