✦ Synopsis

A nasal breath sampling device was developed for use with dairy cattle . This device was tested as a means of supplying breath for analysis by a gas sensor array , gas chromatograph-mass spectrometer , and Fourier transform infrared spectrophotometer . Concentrations of methane , dimethyl sulphide , butan-2one , and propanone (acetone) in cow nasal breath , under field conditions , are reported for the first time , and were detected at 70 -1000 p . p . m ., 80 -100 p . p . m ., 70 -80 p . p . m ., and 1 -10 p . p . m ., respectively . The out-

Although Duchenne muscular dystrophy (DMD) is often associated with sleep disordered breathing (SDB), it is not standard clinical practice to routinely test this population for SDB, and the optimal timing and methodology for such testing has not been established. Our objectives were: 1) to examine t

Recent works in the vibration-based structural health monitoring community have emphasised the use of correlation dimension as a discriminating statistic in seperating a damaged from undamaged response. This paper explores the utility of attractor dimension as a 'feature' and offers some comparisons
