    Notes: [Auszug] Most workers (for example, see refs. 5 and 6) observe, with their stabilizing apparatus, that targets disappear and reappear at short intervals when viewed for several minutes. Sometimes the whole and sometimes part of the target reappears3. One worker7 suggests that all reappearances are due to a ...

    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] Fluorescent tubes contain mercury vapour; the shortwave-length discharge induces a visible radiation from the phosphor coating of the tube walls. During research on another topic3, we observed emission from a typical daylight tube at 313, 334 and 366 mjx as well as in the visible spectrum. It was ...

    Biomechanics: The flight of the dipteran fly (1986)
    [s.l.] : Nature Publishing Group
    Nature 321 (1986), S. 468-469 
    Details
    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] THE wing-beat frequency of flies in the order Diptera varies from 120 Hz in the larger species to more than 500 Hz in the smallest midges. These frequencies are far faster than can be maintained by conventional muscle, where there is one impulse per contraction. The flight muscles of dipteran ...

    Notes: [Auszug] THE idea of reviewing the first few volumes of what is intended eventually to be a 15-volume series on invertebrate anatomy is one that would fill most with gloom. Uppermost is the fear of having to wade through endless irrelevant or unintelligible photomicrographs. The difference in this case, ...

    Notes: [Auszug] LIVING organisms range in size from a diameter of about one hundredth that of a typical human cell to a length of more than 30 metres, with weights ranging from the infinitesimal to that of a medium-sized airliner. The smallest organisms live at an incredible pace. The energy production of a ...

    Notes: [Auszug] Fig, 1 Design for a model swivel wing aircraft made from paper. The paper is about 0.1 mm thick and fins are bent up for the cross winged subsonic condition as shown (--------). For the diagonal winged supersonic condition, new fins are bent at 45 to the span (-o-o-) and the match stick nose weight ...

    Notes: [Auszug] Flies were lightly etherised on the day of emergence and the two sexes were isolated in groups of 10 to 30 into vials containing fresh standard food: 10-15 d later, one individual of each sex was placed in a 12 x 12 x 20 mm wire gauze cage within 5mm of the ribbon of a Grampian GR4 microphone (for ...

    The deep fovea as a focus indicator (1978)

    Notes: [Auszug] It has already been suggested that the convexiclivate fovea acts as a focus detecting spot analogous to those in modern reflex cameras to aid focusing the image10. There are several reasons for such a suggestion. (1) Convexiclivate foveas are placed symmetrically over retinal areas which have ...

    Notes: [Auszug] In order to demonstrate experimentally the characteristics of the stimulation we attempted to provide an analogue for vibration and to see whether it was possible to use this to supplement the courtship of males with their wings removed. Such males have been shown to be very unsuccessful in ...
