EXTENSION OF SIMPLIFIED BISHOP METHOD, SIMPLIFIED JANBU METHOD AND SPENCER'S METHOD TO THREE DIMENSIONS

Simplified Three-Microphone Acoustic Test Method

Accepted acoustic testing standards are available; however, they require specialized hardware and software that are typically out of reach economically to the occasional practitioner. What is needed is a simple and inexpensive screening method that can provide a quick comparison for rapid identification of the top candidates. This research reports on the development of an acoustical rapid-test ...

The PISA method simplified.

We have read with interest the study by Messika-Zeitoun et al. 1 showing that using a fixed angle value of 100 provides an accurate estimation of the miral valve area (MVA) by the proximal isove-locity surface area (PISA) method in patients with mitral stenosis (MS). We appreciate the study as a means to make PISA method more popular in assessing the MVA. Although not cited in the article, we a...

Simplified method of anaerobic incubation.

A method is described that obviates the need for vacuum and tanks of gas mixtures for anaerobiosis in the anaerobic incubator.

A simplified method of investigating stentorrhoea.

Estimation of underwater noise – a simplified method

A set of procedures has been developed to allow preliminary estimates to be made of underwater noise and its effects on marine species. They do not require detailed acoustic survey data, either of the site or of the proposed plant. However, they still facilitate the comparison of different project proposals to assist in the optimisation of equipment layout and routing. Noise may be due to speci...
