As discussed in recent work (Sheppard, C. J. R. & Török, P., J. Microsc., 185, 366–384; Török et al., J. Microsc., 188, 158– 172), two approaches have been used extensively for vectorial computations of high aperture confocal pointspread functions when focusing through a dielectric interface. Whereas the equation by Hell, Reiner, Cremer & Stelzer (J. Microsc., 169, 391–405) is based on the Huyg...

Introduction There are excellent papers covering the molecular epidemiology of spring viremia of carp virus (SVCV; Stone et al., 2003; Miller et al., 2007; Sheppard et al., 2007; Warg et al., 2007), the emergence of SVCV in Asia (Liu et al., 2004; Teng et al., 2007), the impact on fish populations in North America (Goodwin, 2002; Dikkeboom et al., 2004; Garver et al., 2007), and descriptions of...

To the Editor: We read with great interest the excellent article by Basso et al on arrhythmic mitral valve prolapse (MVP) and sudden cardiac death in Circulation. The investigators reported a relatively high prevalence of MVP in individuals experiencing sudden death. Such deaths were more common in young women and were associated with myocardial fibrosis in the papillary muscles and the inferob...

investigating nozzle’s orifice flow is challenging both experimentally and theoretically. this paper focuses on simulating flow inside diesel injector nozzle via ansys fluent v15. validation is performed with experimental results from winkhofler et al (2001). several important parameters such as mass flow rate, velocity profiles and pressure profiles are used for this validation. results includ...

In this research a physical model is presented. A trapezoidal shape of channel with 1.45 m width, 1 meter depth and banks slope of 1H: 1.5V was used. Circular piers (6, 8 and 10cm diameter) were tested under three different flow discharges of 50, 65 and 80 lit/s and three different median bed material sizes equal to 0.94, 1.31 and 2.12 mm. Seven different longitude distance to pier diameter rat...

Two new antihypertensive drugs, bretylium and guanethidine have recently been introduced in therapeutics. These drugs produce a gradual, lowering of arterial blood pressure in animals and man, probably through a specific blocking action on the peripheral adrenergic neurone (Boura and Green, 1959; Maxwell et al., 1959). Guanethidine in addition causes a depletion of the tissue stores of noradren...

The Mode I and II stress intensity factors (K„ Kn) at the two tips of a subsurface crack subjected to a moving compressive load are studied. Coulomb friction along the crack faces results in a number of history dependent slip-stick configurations and nonsymmetric variation in K7 and K/7. The formulation used to study this variation involves a singular integral equation in two variables which mu...
