Spent liquid medium from a number of SRS bacterial cultures enhanced iodide oxidation 2-10 fold in the presence of hydrogen peroxide (HO). From a time-series measurements of peroxidase activities and organic acid concentrations, it was hypothesized that microbial organic acid exudate promoted iodide oxidation via following mechanisms; (1) organic acids interact with HO to form strong iodide oxidizing agents, peroxy carboxylic acids, and (2) organic acid secretion led to enhanced rates of HO-dependent iodide oxidation by lowering the pH of the culture medium.

Times Cited Count:25 Percentile:79.09(Astronomy & Astrophysics)The low-lying structures of the self-conjugate () nuclei Nb and Tc have been investigated using isomeric-decay spectroscopy following the projectile fragmentation of a Ag beam. These represent the heaviest odd-odd nuclei in which internal decays have been identified to date. The resulting level schemes shed light on the shape evolution along the line between the doubly-magic systems Ni and Sn and support a preference for states in odd-odd nuclei at low excitation energies associated with a neutron-proton pairing gap. Comparison with Projected Shell Model calculations suggests that the decay in Nb may be interpreted as an isospin-changing isomer.

As the ITER construction phase approaches, the VV design has been improved and developed in more detail with the focus on better performance, improved manufacture and reduced cost. Based on achievements of manufacturing studies, design improvement of the typical VV sector (#1) has been nearly finalized. Design improvement of other sectors is in progress - in particular, of the VV sector #2 and #3 which interface with the ports for the neutral beam injection. For all sectors, the concept for the in-wall shielding has progressed and developed in more detail. The design progress of the VV sectors has been accompanied by the progress of the port structures. In particular, design of the NB Ports was advanced with the focus on the heat-flux components to handle the heat input of the neutral beams. Structural analyses have been performed to validate all design improvements.

Times Cited Count:21 Percentile:54.59(Physics, Fluids & Plasmas)Although the basic concept of the vacuum vessel (VV) and in-vessel components of the ITER design has stayed the same, there have been several detailed design improvements resulting from efforts to raise reliability, to improve maintainability and to save money. One of the most important achievements in the VV R&D has been demonstration of the necessary fabrication and assembly tolerances. Recently the deformation due to cutting of the port extension was measured and it was shown that the deformation is small and acceptable. Further development of advanced methods of cutting, welding and NDT on a thick plate have been continued in order to refine manufacturing and improve cost and technical performance. With regard to the related FW/blanket and divertor designs, the R&D has resulted in the development of suitable technologies. Prototypes of the FW panel, the blanket shield block and the divertor components have been successfully fabricated.
