Numerical Study on the Potential of Cavitation Damage in a Lead⁻Bismuth Eutectic Spallation Target.

To perform basic Research and Development for future Accelerator-driven Systems (ADSs), Japan Proton Accelerator Research Complex (J-PARC) will construct an ADS target test facility. A Lead⁻Bismuth Eutectic (LBE) spallation target will be installed in the target test facility and bombarded by pulsed proton beams (250 kW, 400 MeV, 25 Hz, and 0.5 ms pulse duration).

Idiopathic portal hypertension associated with systemic sclerosis and Sjögren's syndrome.

We report a patient with idiopathic portal hypertension (IPH) associated with systemic sclerosis (SSc) and Sjögren's syndrome. A 72-year-old Japanese woman was admitted to our hospital because of Raynaud's phenomenon, sclerodactyly, and dyspnea. The patient had splenomegaly, esophageal varices in the absence of extrahepatic portal obstruction, and cirrhosis of the liver.
