Ammonia vapour in the oral cavity as a diagnostic marker for infection with Helicobacter pylori: Preliminary 'proof of principle' pharmacological investigations (2001)
Journal Article
Dun, C., Blac, M., Cowell, D., Penaul, C., Ratcliffe, N. M., Spence, R., & Teare, C. (2001). Ammonia vapour in the oral cavity as a diagnostic marker for infection with Helicobacter pylori: Preliminary 'proof of principle' pharmacological investigations. British Journal of Biomedical Science, 58(2), 66-75

Most current non-invasive tests for Helicobacter pylori depend on the conversion of labelled (13C or 14C) urea to labelled carbon dioxide (13CO2 or 14CO2) and ammonium (NH4+) by the enzyme urease, with the labelled CO2 detected in exhaled air. Despit... Read More about Ammonia vapour in the oral cavity as a diagnostic marker for infection with Helicobacter pylori: Preliminary 'proof of principle' pharmacological investigations.

A number of sensor types were fabricated and tested for their electrical resistance changes to compounds known to be evolved by potato tubers with soft rot caused by the bacterium Erwinia carotovora. On the basis of these tests, three sensors were se... Read More about Development of a sensor system for the early detection of soft rot in stored potato tubers.

A study of the effects of acid on the polymerisation of pyrrole, on the oxidative polymerisation of pyrrole and on polypyrrole (2000)
Journal Article

The polymer products arising from the hydrochloric acid treatment of aqueous pyrrole were shown to have spectroscopic data consistent with alternating pyrrole and pyrrolidine units with varying degrees of ring opening of the pyrrole units. The acid c... Read More about A study of the effects of acid on the polymerisation of pyrrole, on the oxidative polymerisation of pyrrole and on polypyrrole.

A study of methods for evaluating the integrity of plate type heat exchangers used in the dairy industry (2000)
Journal Article
type heat exchangers used in the dairy industry. International Journal of Dairy Technology, 53(1), 13-20. https://doi.org/10.1111/j.1471-0307.2000.tb02650.x

An overview of leak testing methods for heat exchangers is presented. The problems associated with the presence of residual liquid during testing were assessed as it was shown experimentally that complete drainage of plate type heat exchangers is ver...
