Dry rot species of fungi cause brown rot decay, preferentially removing cellulose and hemicellulose from the timber leaving a brittle matrix of modified lignin. The term "dry rot" is somewhat misleading, as both species of fungi "Serpula lacrymans" and "Meruliporia incrassata" require an elevated moisture content to initiate an attack on timber (28–30%). Once established, the fungi can remain active in timber with a moisture content of more than 20%. At relative humidities below 86 percent, growth of "Serpula lacrymans" is inhibited, but it can stay dormant at relative humidities down to 76 percent. These relative humidities correspond to equilibrium moisture contents
Aiken Technical College fall of 1972. One hundred and seventy-seven students enrolled in the first class of what was then the Aiken Technical Education Center. The current campus opened in the winter of 1973. The original ATC campus consisted of three buildings constructed at a cost of $2.3 million — $80,000 provided by Aiken County and the remainder from federal education grants. Founding President Ashley J. Little led ATC from its beginning as a vocationally based training center to its accreditation as a two-year technical college in 1975. The College’s name was changed to Aiken Technical College in 1977. President Little also presided
