PROGRESS ON THE HEATING AND CURRENT DRIVE SYSTEMS FOR ITER
No full textThe electron cyclotron (EC), ion cyclotron (IC), heating-neutral beam (H-NB) and, although not in the day 1 baseline, lower hybrid (LH) systems intended for ITER have been reviewed in 2007/2008 in light of progress of physics and technology in the field. Although the overall specifications are unchanged, notable changes have been approved. Firstly, it has been emphasized that the H&CD systems are vital for the ITER programme. Consequently, the full 73 MW should be commissioned and available on a routine basis before the D/T phase. Secondly, significant changes have been approved at system level, most notably: the possibility to operate the heating beams at full power during the hydrogen phase requiring new shine through protection; the possibility to operate IC with 2 antennas with increased robustness (no moving parts); the possible increase to 2 MW of key components of the EC transmission systems in order to provide an easier upgrading of the EC power as may be required by the project; the addition of a building dedicated to the RF power sources and to a testing facility for acceptance of diagnostics and heating port plugs. Thirdly, the need of a plan for developing, in time for the active phase, a CD system such as LH suitable for very long pulse operation of ITER was recognised. The review describes these changes and their rationale. © 2009 Elsevier B.V. All rights reserved

Pionus cyaniceps Jacquinot & Pucheran 1853
No full textPionus cyaniceps Jacquinot & Pucheran, 1853 Pionus cyaniceps Jacquinot & Pucheran, 1853: 105. IDENTITÉ. — Geoffroyus heteroclitus heteroclitus (Hombron & Jacquinot, 1841). SPÉCIMEN TYPE. — Holotype par monotypie: C.G. 2004-95 (A.C. 1492 A; N.C. 211). Même spécimen que ci-dessus. REMARQUES. C’est surtout le Dr J. Pucheran, qui n’avait pas participé à l’expédition de Dumont d’Urville, qui a rédigé la partie oiseaux du tome trois de Zoologie (Voyage au Pôle Sud et en Océanie). Les deux spécimens C.G. 2004-98 et C.G. 2004-95 lui ont paru suffisamment différents l’un de l’autre pour ne pas être le mâle et la femelle d’une même espèce mais appartenir à deux espèces différentes. Il a de ce fait renommé le spécimen femelle et ainsi créé un synonyme plus récent de Psittacus Geoffroyi heteroclitus Hombron & Jacquinot, 1841.

First year growth in the lithodids Lithodes santolla and Paralomis granulosa reared at different temperatures
No full textThe southern king crab, Lithodes santolla Molina, and stone crab, Paralomis granulosa Jacquinot, inhabit the cold-temperate waters of southernmost South America (southern Chile and Argentina), where stocks of both species are endangered by overfishing. Recent investigations have shown that these crabs show life-cycle adaptations to scarcity of food and low temperatures prevailing in subantarctic regions, including complete lecithotrophy of all larval stages and prolonged periods of brooding and longevity. However, growth and development to maturity are slow under conditions of low temperatures, which may explain the particular vulnerability of subpolar lithodids to fisheries. In the present study, juvenile L. santolla and P. granulosa were individually reared in the laboratory at constant temperatures ranging from 3–15 °C, and rates of survival and development through successive instars were monitored throughout a period of about nine months from hatching. When the experiments were terminated, L. santolla had maximally reached juvenile instar IV (at 6 °C), V (9 °C), or VII (15 °C). In P. granulosa the maximum crab instar reached was II (at 3 °C), V (6 °C), V (9 °C), or VII (15 °C). The intermoult period decreased with increasing temperature, while it increased in successively later instars. In consequence, growth rate showed highly significant differences among temperatures (P<0.001). Growth-at-moult was highest at 9 °C. Rates of survival decreased significantly in juvenile P. granulosa with increasing temperature. Only at 15 °C in L. santolla, was a significantly enhanced mortality found compared with lower temperatures. Our results indicate that juvenile stages of L. santolla and P. granulosa are well adapted to 5–10°C, the range of temperatures typically prevailing in subantarctic marine environments. In spite of causing higher mortality rates, higher rearing temperatures (12–15 °C) should accelerate the rates of growth and maturation, which may be favourable for projects aiming at aquaculture or repopulation of overexploited king crab stocks
