Soft cover. Condición: Very Good. pp514-519. Removed from AMERICAN ANTIQUITY. JOURNAL OF THE SOCIETY FOR AMERICAN ARCHAEOLOGY, Volume 37, Number 4, October, 1972. Wrps. VG. May contain a first or last xeroxed page. Abstract: "The inability to control for variables which affect protein decay is the major problem limiting the use of nitrogen as a chemical method of dating archaeological bone specimens. Of these variables, soil pH, ground water, and temperature are the major factors. In laboratory simulation experiments, we determined the effect of temperature on the time dependent decay rate of bone protein. In this research, 100 mg samples of ground cow bond were sealed in test tubes containing 5 ml of water and heated at temperatures varying from 100 C to 140 C for time periods up to 5 hr. Nitrogen concentration for each sample was determined using a modified micro-Kjeldahl method developed in our laboratory. Using standard regression analysis, we determined the decay rates of nitrogen for each temperature. By extrapolation from these data, we were able to show that differences in mean annual temperature between archaeological sites can have a substantial effect on the decay rate of bone protein.".…
