Keywords : Effect of temperature ;Wind velocity ;Vesicants
Abstract : The time of persistence of a vesicant at a given temperature and wide velocity may be obtain by the expression. Tables for the variation of neta and meu with temperature and wind velocity have been given so that the time of persistence of a vesicant under given conditions can be readily obtained.

Abstract : "The comparative studies on use of a few natural resins as dune sand stabliser are discussed. Guar-gum - a product of Rajasthan desert, Terminalia alata tannins and rosin have proved promising for short-term and emergency use in field, where water, aggregates, skilled manpower and road constructing machines are not available. Effect of compaction on strength has also been studied in order to optimise the thickness of stabilised surfaces required for construction of roads and helipads in sandy areas. Effect of temperature and bacteria on stabilised specimens have also been discussed."
