The effect of temperature on the fluorescence of DOM (2009)
Presentation / Conference Contribution

It is understood that all fluorescence analyses essentially observes the fluorescence of a given sample in a 'quenched state'. Even so, detailed literature concerning the effects of lower temperatures (below 4 degrees Celsius) is surprisingly sparse.... Read More about The effect of temperature on the fluorescence of DOM.

Hilbert huang transform impedance measurement data for cellular toxicity monitoring (2009)
Presentation / Conference Contribution

This paper investigates the Hilbert-Huang transformation (HHT), which is adaptive analysis of nonlinear and non-stationary signals. The aim of this study is to apply HHT to impedance measurement data analysis in order to discriminate different types...

Journal Article

A sensor array system was constructed incorporating electrochemical sensors for hydrogen, carbon monoxide, hydrogen sulfide and ethanol, a ceramic sensor for total volatiles and a dye-based optical ammonia sensor. The system was calibrated using stan... Read More about A sensor system for monitoring the simple gases hydrogen, carbon monoxide, hydrogen sulfide, ammonia and ethanol in exhaled breath.

Paramagnetic particle detection for use with an immunoassay based biosensor (2007)
Journal Article

A biosensor and detection system that can provide measurement of analyte concentration within a test sample in four minutes is presented. The biosensor uses an immunoassay with micrometre-sized paramagnetic particle (PMP) labels for quantification. A...

A study of methods for evaluating the integrity of plate type heat exchangers used in the dairy industry (2007)
Journal Article

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...

Fluorescence analysis of dissolved organic matter in natural, waste and polluted waters - A review (2007)
Journal Article

Dissolved organic matter (DOM) in aquatic systems originates from a range of sources. Some is allochthonous, transported from the surrounding landscape to the water body, and is derived from and influenced by the geology, land use and hydrology of it...
