Animal domestication : an archeological interpretation / by Harriet C. Dinegar.

Abstract

Animal domestication is an ongoing relationship between man and animals characterized by the manipulation or control of the animals' behavior by man. The relationship exists in several forms, which are differentiated by the degree and particular manifestations of control exercised over the animals. Each form of domestication may be recognized archeologically on the basis of material manifestations of the particular form of control by which it is characterized. No form of domestication is unique to a given culture, economy, or period in sociocultural evolution. The relationship has occurred in each of its forms among vastly different cultures since ten thousand years ago, and appears to have occurred, in a relatively non-complex form as many as fifteen thousand years ago among Magdalenian reindeer herders in North Central France.

“…The exception to this is β-HMX, for which the Knudsen cell measurement resulted in a sublimation enthalpy of 161.0 kJ/mol, a lower value than the value of 175.94 kJ/mol obtained by Rosen et al using the Langmuir method . The latter value agrees well with previous measurements by Dinegar and Stammier . Furthermore, the value of 161.0 kJ/mol is lower than the sublimation enthalpy of 161.5 kJ/mol, determined by Taylor and Cookes for the δ-polymorph, which should be more stable. , Taylor and Cookes have noted that it is possible that Cundall et al measured the sublimation enthalpy over a temperature range in which the α to β transformation was likely to occur .…”

“…For the sublimation enthalpy of TNA, the Knudsen cell technique yielded 125.3 kJ/mol, whereas the Langmuir method yielded 116.38 kJ/mol, which is a difference of close to 9 kJ/mol. For PETN, the Knudsen cell measurement of Cundall et al yielded 150.4 kJ/mol, compared to 158.2 kJ/mol obtained by Dinegar and Stammier using the torsion-effusion method . CL-20 is thought to have a possible range of 147.3–169.5 kJ/mol.…”
