Lernanthropus antofagastensis sp. nov. (Copepoda: Lernanthropidae) parasitic on Anisotremus scapularis in Chilean waters,and new records of Lernanthropus trachure (Brian, 1903)

Lernanthropus antofagastensis sp. nov., parasitic on Anisotremus scapularis, and inshore fish of Antofagasta, Chile, is described and illustrated. It resembles five other species of Lernanthropus in its dorsal plate and third leg, but can be distinguished from them by a combination of characters. L. trachuri Brian, 1903, is recorded, its male described and illustrated from specimens collected from Seriolella violacea and Trachurus murphy, taken in the same locality.     

The first instar larva of Aulacoscelis appendiculata n. sp. (Coleoptera: Chrysomelidae: Aulacoscelinae) and its value in the placement of the Aulacoscelinae

Of all of the chrysomelid subfamilies, only the larvae of the Aulacoscelinae remain undescribed. The adults and first instar larva of Aulacoscelis appendiculata sp. n., from Panama are described, as well as the eggs. Larval characters, eggs, and oviposition behaviour are used to relatethe Aulacoscelinae with other chrysomelid subfamilies, in support of what is known to date concerning adult morphology.     

原子第二宇宙速度与电离能普遍公式的推导、实验验证和理论预言

提出了“原子第二宇宙速度”这一新概念,并根据此概念推导出了单电子原子和离子的原子第二宇宙速度和电离能的普遍公式。根据这些公式计算出了100余种单电子原子和离子电离能的具体数值,计算数据与实验数据符合得很好,从而使这一新的理论和计算获得了成功。因现今实验技术的局限性,有些单电子离子的电离能实验值尚未被科学界测出,我们的理论计算值就作为理论预言列出,已获得的成功使我们有理由相信它们将会获得实验验证。本文的概念和计算显然涉及到经典物理与量子物理的关系等原则问题,其物理本质将在后面两篇文章中论述。

高校图书馆新生入馆教育实践

如何高效地利用图书馆获取信息资源是大学生们不可或缺的基本素养,入学之初对大学新生进行入馆教育是重要的一环。本文根据本校图书馆的自身特点,从四个方面对新生入馆教育实践进行了探索,以期新生们尽快地认识大学图书馆,并高效地利用图书馆。     

工程与现代性

现代性是以工程为载体的秩序寻求过程中所展现的矛盾性和悖论性。现代工程作为现代性的最高成果,兼具确定性与不确定性,其不确定性引发工程风险,而现代性的工程化后果又直接导致工程的异化和人的新异化。所以,按照生存论的解释原则,必须看到源自工程异化的人的新异化的工程人类学意味,进而探索解决人类生存危机的有效途径。

The soil mite family Eremaeidae (Acari: Oribatida) in Mongolia,with remarks on distribution and diversity of known genera

The oribatid mite family Eremaeidae is represented in Mongolia by eight species in three genera. Three new species, Eueremaeus tenuisensillatus sp. nov., Eu. crassisetosus sp. nov. and Eu. laticostulatus sp. nov., collected from cool temperate forests, dry steppe and semi-desert habitats in central and southern Mongolia, are described on the basis of adults. Five known species, Eremaeus hepaticus C. L. Koch, Eu. oblongus (C. L. Koch), Eu. granulatus (Mihel?i?), Proteremaeus mongolicus (Golosova) and P. punctulatus Bayartogtokh are redescribed; the first three of these are recorded for the first time from Mongolia. Taxonomic status of Eu. granulatus (Mihel?i?) and Eu. silvestris (Forsslund) is discussed, and the latter is considered a junior synonym of the former species. The following new combinations are proposed: Eueremaeus brevifer (Mahunka), Eueremaeus fossulatus (Kunst) and Eueremaeus roissi (Piffl). A key to Mongolian species of Eremaeidae is given. Data on distribution and diversity of Eremaeidae of the world are discussed.
