Primary Ewings Sarcoma of the Inferior Vena Cava.

Introduction: Sarcomas of vascular origin are rare. A case of Ewings sarcoma of Inferior Vena Cava [IVC] is reported here.

Report: A 36-year-old lady presented with a 6-month history of bilateral pitting lower limb swelling and 1-month history of vaginal bleeding.

Note: On the generation of sub-300 keV flash-X-rays using rod-pinch diode: an experimental investigation.

Generation of flash X-rays (FXRs) at less than 500 keV is described with emphasis on experimental investigation. The pulser is a Tesla transformer-Water transmission line based pulsed power generator operating in double resonance mode to power a rod-pinch diode. The configuration of aspect ratio reported here falls much below the normally reported ratios for the rod-pinch diode operation.
