The application of chemistry to the technological requirements of the mineral industry is attended by problems of communication, isolation and application. Examples of research related to mineral exploration, underground fires, and the treatment of refractory ores suggest that the effective mineral chemist must learn the language of geology, metallurgy and engineering; that he must extend his s...

Thinning of forest stands is widely carried out to minimize the slowing of growth of individual stems that follows from increasing competition among trees as they become bigger. After thinning, there is an increase in the growth rate of remaining trees because of an increase in the availability of resources per tree. Often, there is also an increase in foliar efficiency (biomass increase/foliag...
