赞比亚钴的生产

中国有色冶金 1980年第7期22卷 39-41页

作者： J.r.chadwick 周应杰

赞比亚1978年生产了2,063吨钴,比1977年增加了359吨。可以断定,赞比亚在世界钴生产国中仍居第三位,如钴的发展计划得到实现,它将上升到第二位。表1为世界各国钴产量。

Fully A-doublet resolved differential cross sections and collision-induced rotational alignment moments have been measured for the NO(X)-Xe collision system at a collision energy of 519 cm^-*** experiments combine initial quantum state selection,employing a hexapole inhomogeneous electric field,with quantum state resolved detection,using(1+1')resonantly enhanced multiphoton ionization and velocity map ion *** differential cross sections and polarization dependent differential cross sections are shown to agree well with quantum mechanical scattering calculations performed on ab initio potential energy surfaces[*** et ***.137,014312(2012)].By comparison with quasi-classical trajectory calculations,quantum mechanical scattering calculations on a hard-shell potential,and kinematic apse model calculations,the effects of the attractive part of the potential on the measured differential cross sections and collision-induced rotational alignment moments are assessed.

Sentinel lymph node biopsy has become a well-established and commonplace prac-tice in many oncologic disease sites as a means to stage the regional lymphatics, avoid unnec-essary surgery and decrease patient morbidity. In the head and neck, its role is well established for cutaneous melanoma with proven fidelity and survival benefit. Its role in use for other sites such as oral cavity carcinoma continues to develop with promising results from several recent trials. Although not widely adopted, the potential benefits of sentinel lymph node biopsy in the management of oral cavity carcinoma are apparent. refinements in tech-nology and protocols including development of novel radiopharmaceutical tracers, routine incorporation of detailed anatomic imaging, increasing surgeon experience and development of new intraoperative identification aids will likely lead to improvements in the use and accu-racy of this technique.
