(19) Treatment modalities included: partial temporal bone resection, subtotal temporal bone resection, total temporal bone resection, radical mastoidectomy followed by radiation therapy, radiation therapy alone, and chemotherapy.
(20) In addition, a new dosage concepts has been introduced on the basis of the effective dose on the lines of the recommendations by the IRCP; as a result, the definitions of radiation protection areas and of dosage limit values had to be revised and reworded.
Thermolysis
Definition:
(n.) The resolution of a compound into parts by heat; dissociation by heat.
Example Sentences:
(1) The inactivation of lysozyme caused by the radicals produced by thermolysis of 2,2'-azo-bis-2-amidinopropane can be prevented by the addition of different compounds that can react with the damaging free radicals.

(3) Complications of electrolysis and thermolysis and the pathophysiology of hair regrowth are presented.
(4) The assay involves extraction with diethyl ether, thermolysis of the sulphonylureas at 100 degrees C and trapping of the resulting amines with 2,4-dinitrofluorobenzene.
