    Notes: Abstract Carcinoid tumor of the bile duct is extremely rare. Ten cases have been reported in the literature. This report describes the eleventh case. A 55-year-old woman was hospitalized with biliary stenosis. Sonography (US) and computed tomography (CT) demonstrated a tumor in the upper common hepatic duct (CHD). Percutaneous transhepatic cholangiography showed extraluminal growth of the tumor. The tumor was resected and histologic examination showed carcinoid tumor of the common hepatic duct.

    Notes: A new process has been developed to produce high-energy bulk Pr-Fe-B magnets directly from the melt without the handling of magnetic powder or powderlike ribbons. The process mainly consists of only three steps—casting/hot pressing/annealing—and minimizes the oxygen contamination of magnets. A typical composition of cast alloy is Pr17 Fe76.5 B5 Cu1.5 . Using this type of alloy, a magnetic alignment is easily introduced by hot pressing. Copper plays two important roles: high coercivity and excellent magnetic alignment are achieved simultaneously by the addition of copper. Magnetic properties of hot-pressed Pr17 Fe76.5 B5 Cu1.5 magnets are as follows: Br=12.5 kG, i Hc =10.0 kOe, and (BH)max =36.2 MGOe. The cast alloy of this composition also has an i Hc of 7.4 kOe and a (BH)max of 8.8 MGOe after annealing at 1000 °C for 24 h. The steep rise in the initial magnetization curve indicates a type of nucleation-controlled coercivity mechanism.

    Notes: Abstract The first excited state above the p +19Ne threshold in20Na has been identified at 2.637 MeV (± 15 keV) with Jπ=0+ or 1+ from the20Ne(3He, t)20Na reaction, suggesting this state to be the s-wave resonance in the p +19Ne scattering at stellar energies.
