    Notes: Summary A new converter, transferring energy from water waves into electromagnetic oscillations, i.e. into an alternating electric current, is proposed. In this converter, an oscillating circuit is combined with a plate capacitor immersed into water. The water waves propagate through the capacitor, thus periodically changing its capacity. In the vicinity of the resonance, under certain conditions to be examined in the paper, stable parametrically excited vibrations are generated in the circuit. In order to show that these conditions can be met in practice, the design of a test converter is outlined, and numerically verified.

    A clinical computer database entry form for an intraoperative anesthesiology-based transesophageal echocardiography monitoring service (1993)

    Notes: Abstract Transesophageal echocardiography (TEE) has been increasingly applied to supplement and, in instances, to supplant conventional intraoperative cardiac monitoring. Our body of experience (〉1600 intraoperative TEE procedures), combined with insights gleaned from an intramural quality assurance study, and clinical implications of certain recent advances in the field, led us to develop the following TEE computer database entry form. The form, completed intraoperatively, consists of a patient and surgical procedure demographics section, followed by fields based on the TEE examination. The scans encompass transverse plane basal short axis, long axis, and transgastric views of the heart and great vessels. The two-dimensional echocardiographic, saline-contrast, color flow and pulsed Doppler data represent both right and left ventricular performance, valvular function and specific lesions. This database entry form is intended to serve as a guide for performance of a nominally complete intraoperative study and facilitate maintenance of a TEE archive consistent with current advances.
