OBJECTIVES The recent introduction of transcatheter aortic heart valves into clinical practice has driven the need to develop methodologies to size such valves without access to the annulus in the manner hitherto possible with open heart surgery. To date, sizing has largely been done according to manufacturer-supplied guidelines based on transoesophageal echocardiography or multidetector comput...

The effect of tube diameter on two-phase flow patterns was investigated in circular tubes with inner diameters of 0.6, 1.2, 1.7, 2.6, and 3.4mm using air and water. The gas and liquid superficial velocity ranges were 0.01–50 and 0.01–3m/s, respectively. The gas and liquid flow rates were measured and the two-phase flow pattern images were recorded using high-speed CMOS camera. The flow patterns...

Sir, Figurate or gyrate erythemas include a variety of dermatoses characterized clinically by annular and polycyclic erythemas or plaques with a tendency to centrifugal extension and central healing. In most cases the aetiology remains unknown and elimination of the cause is then not possible. In some cases spontaneous remission of the different types of gyrate erythemas has been observed (1). ...
