Engineering validation for lithium target facility of the IFMIF under IFMIF/EVEDA project
The International Fusion Materials Irradiation Facility (IFMIF), presently in the Engineering Validation and Engineering Design Activities (EVEDA) phase was started from 2007 under the frame of the Broader Approach (BA) agreement. In the activities, a prototype Li loop with the world's highest flow rate of 3000L/min was constructed in 2010, and it succeeded in generating a 100mm wide and 25mm thick with a free-surface lithium flow along a concave back plate steadily at a high-speed of 15m/s at 250°C for 1300h. In the demonstration operation it was needed to develop the Li flowing measurement system with precious resolution less than 0.1mm, and a new wave height measuring method which is laser-probe method was developed for measurements of the 3D geometry of the liquid Li target surface. Using the device, the stability of the variation in the Li flowing thickness which is required in the IFMIF specification was ±1mm or less as the liquid Li target, and the result was satisfied with it and the feasibility of the long-term stable liquid Li flow was also verified. The results of the other engineering validation tests such as lithium purification tests of lithium target facility have also been evaluated and summarized

Enzymatic Generation of Highly Anticoagulant Bovine Intestinal Heparin
Unlike
USP porcine heparin, bovine intestinal heparin (BIH) has
a low anticoagulant activity. Treatment with 6-OST-1, -3, and/or 3-OST-1
afforded two remodeled heparins that met USP heparin activity and
Mw specifications. We explored the pharmacodynamics and pharmacokinetics
in a rabbit model. We conclude that a modest increase in the content
of 3-<i>O</i>-sulfo groups in BIH increases the number of
antithrombin III binding sites, making remodeled BIH behave similarly
to pharmaceutical heparin
