    Damage to Cardiologists’Gloves During Cardiac Catheterization, Pacemaker Implantation, and Percutaneous Transluminal Coronary Angioplasty (1991)

    Notes: Glove perforation during catheter laboratory procedures exposes the operator to potentially infected fluids and the patient to wound infection. To assess the extent of this problem, 200 consecutive pairs of surgical gloves worn during cardiac catheterization, percutaneous transluminal coronary angio-plasty (PTCA), or permanent transvenous pacemaker (PPM) insertion were examined for perforations by a water distension test. The overall puncture rate for pairs of gloves was 18%. The rate of glove puncture differed between cardiac catheterization, PPM implantation, and PTCA (21.4%, 25.6%, and 4.8%, respectively; P = 0.018). The incidence of glove damage at cardiac catheterization was significantly higher when arterial access was obtained by a brachial cut-down rather than by the Seldinger technique (25.7% and 11.3%, respectively; P = 0.015) and was independent of operator experience. Glove perforation is common. Operators should be aware of the problem and be particularly vigilent during brachial arteriotomy and PPM implantation, especially when operating on potentially infected patients.

    Notes: [Auszug] Bass were collected primarily by angling or electrofishing, and the following data were obtained: capture date, location within the reservoir, standard and or total length, and body weight. Body condition (K) was determined using the standard length of each fish. The regression of standard and ...

    Lead Doping of Wet-Chem. PZT 95/5 for Enhanced Electrical Performance in Ferroelectric Power Supply Applications (2006)

    Notes: Wet chemistry produced niobium modified PZT 95/5 was synthesised and processedfor use in a ferroelectric power supply. The electrical performance of ferroelectricpower supply components can be characterised by the remnant polarisation for thematerial, which is found to follow closely with density. The effects of doping the wetchemistry derived oxide powder with additional PbO via a traditional mixed oxideroute were assessed as a function of density and remnant polarisation. The resultshave shown a gradual improvement followed by a sharp deterioration in density andelectrical properties as PbO additions increase and exceed a certain level. As a resultof lead volatilisation during subsequent processing steps, the actual lead content forthe optimum PbO dopant level was in the region of theoretical stoichiometry, whichin part concludes the findings of this study. Further conclusions are made in referenceto the effect of excessive PbO on the material’s processing characteristics
