Synthetic studies on farnesene isomers and homologues from the Dufour glands of ants
Thesis
(1982). Synthetic studies on farnesene isomers and homologues from the Dufour glands of ants

(Z,E)-q-farnesene and its homologues homo-, bishomo- and trishomo-farnesenes had been identified as constituents, of the Dufour gland secretion of several species of Myrmica ant. Although farnesene isomers had been found previously in plant and insec... Read More about Synthetic studies on farnesene isomers and homologues from the Dufour glands of ants.

The application of code conversion techniques to digital audio systems
Thesis
(1982). The application of code conversion techniques to digital audio systems

The recent development of low cost digital storage has made digital audio systems attractive. However its popularity depends on the development of accurate low cost digital to analogue (D/A) converters. Existing converters require the fabrication of...
