James Anderson's powerful critique of Adam Smith's position on the corn export bounty was published in 1777. It focuse d on Smith's proposition that the bounty could not lead to increased corn production because it could not increase corn's real price. Smit h's response to the critique is traced in later editions of Wealth of Nations. While Anderson's critique of Smith influenced Thomas Malthu s's writings from 1803 onwards, his theory of differential rent did n ot influence Malthus at this stage. An examination of the evolution o f Malthus's ideas on rent between 1803 and 1815, however, indicates t hat Malthus knew and used Anderson's work on rent.

The effect of the deacetylated (amine) metabolite of diamphenethide (DAMD, 10 mug ml-1) on the uptake and incorporation by adult Fasciola hepatica of radioactively labelled precursors of DNA, RNA and protein synthesis ([H-3]thymidine, [H-3]uridine and [H-3]leucine, respectively) was measured by liquid scintillation counting. Comparison was made between the effects of DAMD and those of specific inhibitors of DNA, RNA and protein synthesis, namely, 5-fluorouracil, cordycepin and cycloheximide, respectively. DAMD caused a significant decrease in the overall uptake and incorporation of [H-3]uridine by F. hepatica, decreased the incorporation of [H-3]leucine and also caused a significant decrease in the overall protein content of the flukes. The effect of DAMD was similar to that of cycloheximide (I x 10(-3) M), a potent inhibitor of protein synthesis, which also caused a significant decrease in the incorporation of [H-3]leucine by the fluke and a decrease in the overall protein content of the fluke. Cordycepin(100 mug ml-1) caused a significant decrease in the protein content of the fluke, but had no effect on the uptake or incorporation of [H-3]uridine. 5-Fluorouracil (I x 10(-4) m) did not affect the uptake or incorporation of VH]thymidine, nor did it decrease the protein content of the fluke. The results indicate that DAMD inhibits protein synthesis by F. hepatica, possibly by inhibiting RNA synthesis. The results are also consistent with previous morphological investigations involving DAMD.

Pulsed laser deposition (PLD) from a hot pressed manganese doped ZnS target using a KrF laser, has produced a high rate deposition method for growing luminescent thin films. Good stoichiometric quality and typical luminescent crystal structures have been observed with a predominant hexagonal phase and little evidence of the cubic phase. The luminescent characteristics were determined by cathodoluminescence and photoluminescence excitation and stable electroluminescence was observed under pulsed dc conditions with a minimum brightness of 150 cd/m2. PLD film characteristics are compared with those observed in radio-frequency sputtered samples.
