    This webpage is part of a larger site by the author about electronic circuit engineering. This page introduces the reader to capacitors, including the principles behind how they work. Explanations of several different types of capacitors (including Electrolytic, Tantalum, and Mica) are accompanied by detailed color illustrations of the concepts

    Five species of lecideoid lichens belonging to three genera are reported as new to the flora of the Prince Olav Coast and the Soya Coast, Enderby Land, East Antarctica; they are Carbonea capsulata (DODGE & BAKER) HALE, Lecidea andersonii R. FILSON, Lecidea cancriformis DODGE & BAKER, Lecidea soyaensis M. INOUE and Lecidella siplei (DODGE & BAKER) M. INOUE. All are endemic to Antarctica. An examination was made of the collections from the region, which were collected mainly by the author under the project of the 27th Japanese Antarctic Research Expedition (JARE-27,during January 1986 and February 1987). The type and authentic specimens of possibly related species have been restudied. Lecidea soyaensis M. INOUE is new to science and Lecidella siplei (DODGE & BAKER) M. INOUE is proposed as a new combination. Taxonomic and chemical data as well as a key to the known taxa are provided

    The Hobby of Electronic Circuit Engineering

    No full text
    This website (originally created in Japanese and translated into English using translation software) by a Japanese systems engineer, Seiichi Inoue, provides an extensive overview of electronic circuit engineering. Topics covered include: Basic knowledge of Electronic parts, Basic knowledge of Engineering Instruments, an Introduction of Engineering Method, and the Assembly Process. A variety of electronic circuits and their uses are provided, as well as a separate section on PIC electronic circuits. The language may be difficult to follow at times given the translation, but still a gem of a site for anyone wanting to build some circuits! Keep in mind that in some sections, the author notes that he is &quot;describing while studying, there seems to be mistakes in the contents. Do at your own risk.&quot; For some further browsing, he includes sections on his other interests, such as 3D photography, java programming, CAD, Japanese customs and the Japanese language

    Simultaneous large values and dependence of Dirichlet LL-functions in the critical strip

    No full text
    We consider the joint value distribution of Dirichlet LL-functions in the critical strip 12<σ<1\frac{1}{2} < \sigma < 1. We show that the values of distinct Dirichlet LL-functions are dependent in the sense that they do not behave like independently distributed random variables and they prevent each other from obtaining large values. Nevertheless, we show that distinct Dirichlet LL-functions can achieve large values simultaneously infinitely often.Comment: 24 page
