Pulmonary Thromboembolism Presenting as Multiple Pulmonary Cavities.

A 38 years old male patient presented to the emergency department with acute severe retrosternal chest pain and was found to have pulmonary thromboembolism. The patient developed new necrotic lung cavities each day due to the dissemination of emboli from the thrombus. The cause of thrombus was found to be protein C deficiency, which is an inherited thrombophilia. The interesting features in thi...

Planar soap bubble clusters with multiple cavities

The floppiness of bubble chains and the rigidity with respect to slidings of three-bubble clusters are used to construct numerically degenerate local energy-minimizing bubble clusters in the plane with as many cavities as desired. Experimental demonstrations are also given. © 2009 Elsevier Ltd. All rights reserved. 1. Formulation of the problem and experimental demonstration The purpose of this...

Multiple Extraction Cavities for High Power Klystrons*

. The design, performance, and comparison with 2-D computer simulations of an X-band high power klystron amplifier utilizing an output circuit consisting of two uncoupled output cavities are described. It is shown that good efficiency, low RF gap gradient, relatively uniform power extraction from each cavity, and freedom from oscillations due to extraneous modes can be achieved. The change in p...
