    Get PDF
    The effects of weightlessness on small living organisms, and methods for improving biological techniques were investigated in the seven experiments reported in this pamphlet which is intended as a curriculum supplement for secondary schools. Topics include: (1) killfish hatching and orientation; (2) microbial growth and changes in biorhythm; (3) cell separation by electrophoresis; (4) microbial exchange in the space raft; and (5) changes in astronaut immunity during spaceflight. The pamphlet is intended as a curriculum supplement for secondary schools

    Write This Down: A Model Market-Share Liability Statute

    The 1980s featured a remarkable series of lawsuits: the DES cases. The women who brought these cases had been harmed by a drug—DES—that their mothers had taken while the future plaintiffs were in utero. Hundreds of companies manufactured DES, each unit of DES sold was chemically identical, and the harmed women were generally unable to identify the manufacturer who had filled their mothers’ prescriptions. Many of the plaintiffs could not prove causation as to a specific manufacturer and so could not bring traditional tort suits. To provide relief, some courts forged ahead with a new tort theory: market-share liability. Under this theory, plaintiffs who were harmed by a fungible product and unable to identify the manufacturer who produced the unit that harmed them could sue all manufacturers of the product and collect from each of them according to their market share. But not every court recognized this new theory. And among the courts that did, disagreement emerged as to doctrinal determinations and mechanical considerations. This Note is the first survey of both the legal and practical questions surrounding claims based on market-share liability, from whether a prospective plaintiff qualifies for such a cause of action to determining the relevant market to pleading requirements. It asserts that market-share liability furthers the purposes of tort and products-liability law, critiques existing state statutory schemes, and proposes a model statute for state legislatures to consider

    Measuring the Expansion of the Universe Through Changes in the CMB Photosphere

    Full text link
    The expansion of the universe may be observed in ``realtime'' by measuring changes in the patterns of the anisotropy in the CMB. As the universe ages, the surface of decoupling--or the CMB photosphere--moves away from us and samples a different gravitational landscape. The response of the CMB to this new landscape results in a different pattern than we observe today. The largest change occurs at l~900. We show that with an array of detectors that we may envision having in a couple of decades, one can in principle measure the change in the anisotropy with two high precision measurements separated by a century.Comment: 4 pages, 8 figures, submitted to Ap

    Apollo-Soyuz pamphlet no. 3: Sun, stars, in between

    Get PDF
    The structure of the sun and its surface temperature and brightness are discussed as background for explaining the ASTP joint experiment to photograph the solar corona from Soyuz while the Apollo spacecraft created an artificial eclipse by blocking out the sun. Stellar spectra, stellar evolution, and the Milky Way galaxy are explored in relation to the MA-083 experiment to survey the sky for extreme ultraviolet sources and background radiation. Interstellar gas and the spectrum of helium are discussed in relation to the MA-088 experiment designed to detect interstellar helium entering the solar system and to measure its density and motion

    Apollo-Soyuz pamphlet no. 5: The earth from orbit

    Get PDF
    Astronaut training in the recognition of various geological features from space is described as well as the cameras, lenses and film used in experiment MA-136 to measure their effectiveness in photographing earth structural features from orbit. Aerosols that affect climate and weather are discussed in relation to experiment Ma-007 which relied on infrared observations of the setting or rising sun, as seen from Apollo, to measure the amount of dust and droplets in the lower 150 km of earth's atmosphere. The line spectra of atomic oxygen and nitrogen and their densities at 22 km above the earth's surface are examined along with experiment MA-059 which measured ultraviolet absorption at that altitude
