OBJECTIVE: To obtain a representative national picture of the type of people with asthma attending accident and emergency (A&E) departments in the UK, the reasons why they attend, and to determine the proportion admitted to hospital. DESIGN: A nation

A method of measuring the viscoelastic properties of an electrorheological fluid (corn starch in mineral oil) using oscillatory flow in a thin rectangular tubular channel is described. The channel is formed by two conducting plates separated by insul

A new method of measuring and analyzing the clinically significant structural characteristics of blood clots is described, using an oscillatory flow instrument (Vilastic-3 Viscoelasticity Analyzer). The development of the viscous and elastic properti

The elastic yield stress is a key parameter in the way human blood flows, because after yielding the microstructure formed by the red cells undergoes a dramatic change and the blood is transformed to a superfluid state. This yielding of the structure

Theories of flow birefringence in steady and oscillatory shear flow for spheroidal particles are compared. It is shown, that proper normalization of birefringence functions make them identical for both flows at low gradients and frequencies. The devi

The theory for the frequency‐dependent properties of dilute polymer solutions, i.e., flow birefringence, acoustic birefringence, and viscosity, has been developed by Peterlin using the Gaussian necklace model and incorporating the internal viscosit

Summary In successive years since the opening of a Coronary Care Unit at Westminster Hospital the mortality has been 26 and 20% and for the first 4 months of 1968, 5·3%. Overall mortality for 260 patients was 20%. Resuscitation has been successful i

A theoretical and experimental study of the shear‐wave field and the associated optical birefringence produced by interfering primary and reflected wavetrains propagating in a viscoelastic medium is presented. The shear‐wave field is generated by

A theory for the behavior of dilute solutions of polymer molecules in oscillatory shear has been given by Zimm. Two variable parameters are contained in the theory, these being the number of statistical chain segments which are joined by bead joints

A system for the measurement of time-varying ellipticity and axis orientation of polarized light has been developed and specifically applied to the analysis of the birefringence of macromolecular solutions in a Kerr electro-optic cell. The method of
