DETECTION OF CARDIAC DISTURBANCES FOLLOWING THORACIC TRAUMA WITH HIGH-FREQUENCY ANALYSIS OF THE ELECTROCARDIOGRAM
Autor: T. D. Schick, S. R. Powers, H. van der Zee
Publikováno v: The Journal of Trauma: Injury, Infection, and Critical Care. 17:419-424
High-frequency electrocardiograms (HF-ECG) were recorded from rabbits before and after delivery of blunt, nonpenetrating thoracic trauma. The conventional electrocardiographic record showed transient changes following the blow; the HF-ECG showed dist

Correction factors for sizing transparent fibres using light scattering
Autor: S R Powers, D J Somerford
Publikováno v: Journal of Physics D: Applied Physics. 15:403-409
Correction factors are presented which enable Fraunhofer diffraction to be used to determine the diameters of transparent fibres. Fibre diameters in the range 4 to 80 mu m are considered. It is shown that if the refractive index lies between 1.45 to

Bucrylate (isobutyl 2-cyanoacrylate) was used for the transcatheter embolization of the splenic artery in 4 patients with bleeding gastric varices secondary to splenic vein thrombosis, 3 patients with symptoms of hypersplenism, and 8 patients with bl

Error contour charts relevant to fibre sizing using light scattering
Autor: D J Somerford, S R Powers
Publikováno v: Journal of Physics D: Applied Physics. 12:1809-1818
Error contour charts are presented which compare the approximate Fraunhofer diffraction theory with the exact solution of Maxwell's equations for infinitely long cylinders of circular cross-section. The comparison is made over angular ranges which ex

An Instrument for the Measurement of Cardiac Output
Autor: S. R. Powers, E. M. Papper, H. H. Rossi
Publikováno v: Review of Scientific Instruments. 23:178-181
A modification of the injection technique for the determination of cardiac output is presented in which the injected material is a radioactive isotope (Na24). The measurement is performed with a recording unit which consists of a counting chamber, a
