Articles with 100 citations or more in the scientific literature and with at least one author with Brazilian affiliation, were identified in the Thomson-ISI (Institute for Scientific Information) Web of Science bibliometric database covering a 10-year period, from 1994 to 2003 (see Packer and Meneghini 2006); 248 (0.23%) out of a total of 109,916 articles with Brazilian affiliation were identified. This study was primarily carried out to identify thematic nuclei of excellence in research that had major impact in the international literature. Twelve of these nuclei in the fields of Biomedicine, Medicine, Biology, Physic, Chemistry and Astronomy were considered outstanding and their genesis and development were described. The weight of factors such as international collaboration and network organization are distinct in these areas and the reasons for that are discussed.
在汤姆森-ISI（科学信息研究所）的科学引文索引数据库中，对1994年至2003年这10年间在科学文献中被引用100次及以上且至少有一位作者隶属于巴西机构的文章进行了检索（见帕克和梅内基尼，2006年）；在总共109,916篇隶属于巴西机构的文章中，识别出了248篇（占0.23%）。本研究主要旨在识别在国际文献中产生重大影响的卓越研究主题核心。生物医学、医学、生物学、物理学、化学和天文学领域的12个此类核心被认为是杰出的，并对其起源和发展进行了描述。国际合作和网络组织等因素在这些领域的重要性各不相同，并对此进行了讨论。
