    Tannic Acid Effects on Raphanus Raphanistrum Root Acid Phospatase
    (2000-12) Yu, Karl O. A.; Fried, Colleen A.; Hall, Prudence J.
    The effects of tannic acid (TA) on acid phosphatase (APase) (E.C.3.1.3-2) from root extracts of fertilized or unfertilized Raphanus raphanistrum plants were examined. TA inhibited APase activity non-competitively; Vmax was reduced, but the apparent K^ was unaffected in the presence of added TA. Endogenous tannin content ranged between 0.26 and 0.56 (Imoleg fresh weight * of root tissue. Enzyme activity data was extrapolated to provide estimates of activity in the absence of any TA; uncorrected APase activity of R. raphanistrum was underestimated by an average of 25%. Addition of polyvinylpyrrolidone (PVP) did not affect measured enzyme rates in a consistent manner.

    Lessons from a Dam Failure
    (2000-12) Evans, James E.; Mackey, Scudder D.; Gottgens, Johan F.; Gill, Wilfrid M.
    The IVEX Dam (Chagrin River, northeastern Ohio) failed catastrophically on 13 August 1994, releasing 38,000 m3 (about 10 million gallons) of impounded water and sediment. This event was triggered by a 70-year rainfall event (13.54 cm of rainfall within 24-hours), resulting in flows 1.9 m above the top of the spillway and impinging on the top of the dam. The failure was the result of seepage piping at the toe of the dam, near the masonry spillway-earthen dam contact. Eyewitnesses reported that collapse of the seepage pipe created a breach in the dam that rapidly downcut. Paleohydrologic modeling suggests peak discharge through the breach was about 466 m'sec1, substantially dewatering the reservoir in approximately 2-3 minutes.

    A Centennial History of the Ohio Journal of Science
    (2000-12) Burk, William R.
    On the occasion of the centennial ofThe Ohio Journal of Science, this paper provides a short history of its development. From an inaugural issue of 16 pages in November 1900, The Journal has matured into an important serial featuring peer-reviewed articles in science, engineering, technology, and education, or their applications; book reviews; four special issues devoted to a theme; Academy presidential addresses; and obituaries of deceased members. Guided over the years by a sequence of 18 editors, The Journal has undergone title changes as its disciplinary scope broadened: The O.S.U. Naturalist (Nov-Dec 1900), The Ohio Naturalist (Jan 1901-Jun 1914), The Ohio Naturalist and Journal of Science (Nov 1914-Jun 1915), and The Ohio Journal of Science (Nov 1915-present). In the past century The Journal has developed from an Ohio natural history serial to an interdisciplinary science journal of international use and respect. Copies are sent to 1900 individuals and organizations, including 37 foreign countries.
