The Extra-Normal Voice

This chapter presents an overview of new developments in vocal exploration. Beginning with a discussion of multiple parameters involved in voice production, this chapter identifies the crucial role that non-linear phenomena has in the performance of the extra-normal voice. In this article, two related taxonomies are presented (source production related to degree of voicing; emphases within the aco

Facile synthesis of fatty acid esters in high yields

The facile synthesis of esters by lipase-catalysed esterification of fatty acids and ethanol is demonstrated. Evaporation of the water generated in the reaction allowed the rapid production of esters of >99% yield in refluxing pentane or hexane. Water was trapped by condensing the refluxing vapor phase and passing it over activated molecular sieves in a reflux trap. High yields were rapidly obtain
