In April 2016 Manchester eScholar was replaced by the University of Manchester’s new Research Information Management System, Pure. In the autumn the University’s research outputs will be available to search and browse via a new Research Portal. Until then the University’s full publication record can be accessed via a temporary portal and the old eScholar content is available to search and browse via this archive.

Abstract

In the truffle detection appts., ambient air from near the ground being searched is drawn into an inverted funnel (12) and then through a sampling head (18) by a pump (17) which is located in a supporting tube (13). Polymeric detector heads (1) are fixed half way along the sampling head (18).The upper end of the tube (13) has a handle (15) attached to a box (14) which houses a microcomputer and its peripherals which allow the relative changes in the electrical resistances of the various detectors to be compared to those corresponding to the presence of truffles.ADVANTAGE - Difficulties of training and transporting dogs or pigs are avoided as well as operating losses due to animals eating truffles.
