184 LLE Review, Volume 72 Current target designs for laser-driven inertially confined fusion experiments require that the laser drive pulse be tailored to the target, i.e., that the pulse have some temporal shape other than Gaussian. On the 60-beam OMEGA1 laser system this is accomplished by placing an electro-optic modulator at the input of the system, which is driven by an electrical pulse fr...

This communication describes and discusses the results obtained in studying central and )eripheral arterial pressure pulses in man by means of retrograde aortic catheterization. The pressure pulse transformation and pulse transmission in the aorticobrachial system are presented and compared with comparable tracings reported in the dog. Several normal subjects and patients with hypertension, aor...

A palpable dicrotic pulse was observed in 18 patients after open heart operation, usually after prosthetic replacement for aortic regurgitation (14 of 18 patients). Two patients had a ventricular septal defect, one had aortic stenosis, and one, mitral insufficiency. The ages of the patients ranged from 9 to 63 years, but the dicrotic pulse was more prominent and persisted longer in younger pati...

Photoplethysmography is a non-invasive, electro-optical technique for detecting the cardiovascular pulse wave generated by elastic nature of the peripheral vascular arteries by the contraction of heart. Photoplethysmogram (PPG), a pulse wave generated varies in accordance to blood volume changes in the microvascular bed of a tissue. This review paper emphasizes on the earlier works on the desig...

For large particles, the tail of the pulse is relatively long, and if a smaller particle passes through the sensor volume while the tail still elevates the detector voltage, the smaller particle may produce a pulse that exceeds the counting threshold for large particles . . . Because small particles in ambient air are much more numerous than large particles, it is the small particle concentrati...

INDIAN PEDIATRICS 204 VOLUME 41FEBRUARY 17, 2004 from about 1968. The very reasons for multiple doses of OPV and the need for pulse immunization are the occurrence of vaccine failure of three doses of OPV. Dr Paul is not on firm grounds when he declares that polio cannot be eradicated without first discovering the reason(s) for vaccine failure. Vaccine failure can be overcome by increasing the ...

sure. Isoproterenol produced increases in cardiac output and heart rate greater than that achieved with glucagon alone and also increased arterial pulse pressure, stroke volume, and mean rate of left ventricular ejection and decreased systemic vascular resistance. The same doses of isoproterenol and glucagon in combination produced a greater effect on cardiac output than that achieved with eith...
