These properties were determined on a Yerzley mechanical oscillograph
AYO-IV (ASTM D-945).
The tracheal contractions were recorded on Oscillograph
. When the maximal insulin induced contraction was obtained, the tracheal strip was washed three to four times and was allowed to relax passively6.
was used for recording tracheal muscle contraction.
The original Yerzley mechanical oscillograph
was developed to study dynamic properties of polychloroprene for the evaluation of these characteristics in applications such as vibration absorbers (ref.
The time response of VOA was observed and recorded through an oscillograph
The contractile intestinal responses were recorded isotonically by using Bioscience transducers coupled with Oscillograph
. The tissues were allowed 30 min incubation for equilibration prior to addition of any test material and were subsequently stabilized through repeated exposure to sub-maximal concentration of acetylcholine (Ach; 0.3(mean)M).
Diagram XY of older insulation is shown in oscillograph
screen in Fig 2a.
Waveform data can be downloaded using the IPSplot Oscillograph
analysis software that allows for plotting and printing of the downloaded oscillographic data.
Output from the flowmeter was recorded on a Gould 6-channel oscillograph
Instrumentation: Advanced Yerzley oscillograph
(AYO-IV) for testing physical properties of rubber specimens as per ASTM D-945-16
The AYO-IV (Yerzley mechanical oscillograph
) testing machine for dynamic testing of rubber is available from the company.
