    On the geometric form of volcanoes - Comment (1982)
    In:  Other Sources
    Details
    Publication Date: 2011-08-18
    Description: The model of Lacey et al. (1981) accounting for the geometric regularity and approximate cone shape of volcanoes is discussed. It is pointed out that, contrary to the model, volcano eruptions do not occur randomly in elevation and azimuth, but are commonly restricted to summit vents and a few well defined flank zones, so that the form of a volcano is determined by its vent locations and styles of eruption. Other false predictions of the model include the constancy of lava volumes at all vent elevations, the increase in volcano radius as the square root of time, a critical height for volcano growth, the influence of planetary gravity on volcano height and the negligible influence of ash falls and flows and erosional deposition. It is noted that the model of Shteynberg and Solov'yev, in which cone shape is related to stresses due to increasing cone height, may provide a better understanding of volcano morphology.

    Eruption forecast for Krafla caldera (1982)
    In:  Other Sources
    Details
    Publication Date: 2011-08-18
    Description: Based on measurements and timings of 19 previous activity cycles of the Krafla caldera in Iceland that were previously reported, patterns are noted that have apparently not been described before and that appear to offer additional predictive possibilities for the time, place, and extent of near-future events at Krafla. A plot of elapsed time for each deflation event in the current Krafla rifting episode taken from Bjornsson et al. (1977, 1979) suggests that the next event should occur before the end of May, 1982. Comparison of the sites of main fissuring suggests that the next event will be close to or within the caldera, and that an eruption is to be anticipated. The trend for erupted lava area indicates that the next eruption will be larger than its predecessors.

    Searching for impact craters using space shuttle photography (1984)
    In:  Other Sources
    Details
    Publication Date: 2019-01-25
    Description: Extrapolation of impact cratering rates derived from Canada and Europe suggests that in the cratonic regions of Australia, India, Africa, and Brazil, 14-15 impact craters 20 km diameter should have formed during the last 120 my, and survived erosional erasure. In fact, in these areas, only 2 craters are known that approximately qualify: (1) Gosses Bluff, 22 km, 130 + or - 6 my old, and; Strangways, 24 km and 150 + or - 70 my old. It is therefore likely that about a dozen relatively large and preserved impact craters await discovery in these less explored cratons. A larger number of younger and smaller craters must also exist. An informal search is reported for impact craters using photographs obtained by Shuttle astronauts. Photographs taken with the 250 mm lens on Hassalblad cameras have a resolution of 25 m and cover a nominal area of 50x60 sq km. A larger format Linhof camera with similar resolution but 4 times larger area was flown March 1984, and will fly again in the future. Shuttle imagery has numerous advantages in looking for impact craters and for other types of Earth observations.

    Side effects of antimotion sickness drugs (1984)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: The effects on operational proficiency of the antimotion sickness drugs scopolamine, promethazine and d-amphetamine are tested using a computerized pursuit meter. Proficiency is not significantly affected by oral doses of 0.25 mg or 0.50 mg scopolamine but is descreased by oral or I.M. doses of 25 mg promethazine. The performance decrement associated with 25 mg oral promethazine is prevented when combined with 10 mg oral d-amphetamine. The combination of 25 mg I.M. promethazine, 25 mg oral promethazine and 10 mg d-amphetamine produces less performance decrement than oral or I.M. doses of promethazine alone, though more performance decrement than a placebo. I.M. promethazine is adsorbed slowly and consequently may provoke drowsiness.

    Experimental motion sickness - Efficacy of transdermal scopolamine plus ephedrine (1981)
    In:  Other Sources
    Details
    Publication Date: 2019-08-28
    Description: A double-blind, placebo-controlled study compared the efficacy of transdermal therapeutic system-scopolamine administered alone and combined with ephedrine sulfate given orally in doses of 12.5, 25, and 50 mg. Eight normal male students were exposed to stressful accelerations in a slow-rotation room after receiving 10 apparently identical treatments comprising the four drugs and six placebos. Efficacy of the drug was defined in terms of the placebo range and categorized as beneficial, inconsequential, or detrimental. None of the effects was detrimental. Overall beneficial effects were 60% for transdermal therapeutic system-scopolamine (plus placebo) and 57% for the three transdermal therapeutic system-scopolamine plus ephedrine combinations.

    Antimotion-sickness efficacy of scopolamine 12 and 72 hours after transdermal administration (1982)
    In:  Other Sources
    Details
    Publication Date: 2019-08-27
    Description: The antimotion sickness remedy, transdermal therapeutic system-scopolamine, administered in this experiment was scheduled to deliver 1.0 mg of scopolamine over a period of 3 d, and this paper compares its efficacy 12 and 72 h after administration. In a double-blind study, six male college students were individually exposed to a standardized provocative test in a slow rotation room after six apparently identical treatments comprising four placebos and two medications. Efficacy was categorized as beneficial, inconsequential, or detrimental. None of the responses was detrimental. Following the first administration of the therapeutic system, there were four beneficial responses after 12 h but none was beneficial after 72 h. Following the second treatment regimen, there were four beneficial responses after 12 h and three beneficial responses after 72 h. Great individual differences were demonstrated, two subjects accounting for six beneficial responses and two accounting for only one beneficial response. The difference in efficacy after 12 and 72 h has practical and theoretical significance.
