Times Cited Count：1209 Percentile：99.97(Microbiology)The tree of life is one of the most important organizing principles in biology. Gene surveys suggest the existence of an enormous number of branches, but even an approximation of the full scale of The Tree has remained elusive. Here, we use newly available information from genomes of uncultivated organisms, along with other published sequences, to present a new version of the Tree of life, with Bacteria, Archaea and Eukaryotes included. The depiction is both a global overview and a snapshot of the diversity within each major lineage. The results imply the predominance of bacterial diversification and underline the importance of organisms lacking isolated representatives, with substantial evolution concentrated in a major radiation of such organisms.

Times Cited Count：1 Percentile：12.1(Engineering, Electrical & Electronic)The ITER Poloidal Field Conductor Insert (PFCI) was constructed to characterize the performance of selected cable-in-conduit NbTi conductors for the ITER Poloidal Field (PF) under relevant operating conditions. The PFCI was installed and tested inside the bore of the ITER CS model coil, which provides the background magnetic field. The PFCI is a single-layer solenoid, wound from about 50 m of a full-size ITER cable-in-conduit conductor. The winding diameter and height are about 1.5 m and 1 m, respectively. The nominal design current of the conductor is 45 kA at 6 T and 5 K. The main items in the PFCI test programme are current sharing temperature (Tcs) measurements, critical current (Ic) measurements and AC loss measurement. The key technology of the installation, the test methods and procedures, and some preliminary results of the testing campaigns are described and discussed in this paper.

Times Cited Count：4 Percentile：29.39(Engineering, Electrical & Electronic)The PFCI will be tested at JAEA Naka, inside the bore of the ITER Central Solenoid Model Coil. The main test program are the DC characterization of the conductor, the measurement of AC losses in conductor, the hydraulic characterization, the stability and the quench propagation, and the effects of cycling electromagnetic load. Based on and in support of this test program, an extensive campaign of predictive analysis has been initiated on a subset of the above-mentioned test program items and the results of the comparison of selected predictions from different laboratories will be presented and discussed. A sudden quench at 5.7-6.2 K and 45 kA is predicted. The computed temperature increase at the winding outlet is about 0.5 K for the pulse. These results will be compared with the experiment and used for an accurate prediction of the PF coil performance.

Times Cited Count：7 Percentile：40.69(Engineering, Electrical & Electronic)As the test of the PFCI is foreseen at JAERI Naka, Japan, it is essential to consider in detail the lessons learned from the short NbTi sample tests, as well as the issues left open after them, in order to develop a suitable test program of the PFCI aimed at bridging the extrapolation gap between measured strand and future PF coil performance. Here we consider in particular the following issues: (1) the actual possibility to quench the PFCI conductor in the TCS tests before quenching the intermediate joint, (2) the question of the so-called sudden or premature quench, based on SULTAN sample results, applying a recently developed multi-solid and multi-channel extension of the Mithrandir code to a short sample analysis; (3) the feasibility of the AC losses calorimetry in the PFCI. These results show that Tcs measurement and the calorimetric measurement of AC losses will be carried out successfully. However, we need further analytic works for the problem of the sudden quench.

In April 1997 the Japan Nuclear Cycle Development Institute (JNC)commissioned a Three-Task project from the Bretish Geological Survey (BGS). Task 1 was a continuation of work started in 1996 to examine microbial effects on redox and to quantify the effects of microbiological perturbations on the geological disposal of HLW(TRU). Task 2 was commissioned to provide information on theTsukiyoshi Fault for use in ongoing work at the Tono Geoscience Centre. Task 3 was to draft a Technical programme for use in ongoing work at the Tono Geoscience Centre.Task 3 was to draft a Technical programme for a geochemical study of the Tono site. This report details the results of Task 1, undertaken in 1998/99.

In February 1996 the Power Reactor and Nuclear Fuel Development Corportation(PNC)of Japan commissioned a one year study from the British Geological Survey(BGS)to examine microbial effects on redox and to quantify the effects of microbiological perturbations on the geological disposal of HLW(TRU). The work was splitinto two tasks: Tas k 1:SKB REX Cooperation 'To perform laboratory experiments on bacterial processes to assess their influences on redox'.or Task 2:Microbiol ogical modelling the BGS developed code MGSE. This report details the results of Task 1.
