    Notes: [Auszug] LIKE the poor, and often for the same reasons, nationalized industries are always with us. Even where the prevailing ideology is dead set against the notion that government should shoulder tasks that might be put out instead to private persons, as in the United States, nobody would seriously ...

    Notes: [Auszug] THE UK Science and Engineering Council (SERC) is worried that British industry is not taking enough notice of its engineering research - despite the fact that the council, under successive chairmen, has been edging more and more towards engineering. So it has commissioned the London-based Technical ...

    Notes: [Auszug] The nature of stars exploding as Type 1 supernovae (preSN1) is not well understood (see review by Trimble1). First there is the problem of masses of preSN1; the argument that SN1 explosions are not associated with the spiral structure of galaxies2 means only that preSN1 masses should be 〈 7-8M? ...

    Notes: [Auszug] Metastability is one of the most striking yet enigmatic aspects of perception1-5. Necker cubes (Fig. 1) and other bistable figures are often used to illustrate the point that perception is really a hypothesis on the state of affairs in the world rather than a passive response to sensory stimuli. ...

    Notes: [Auszug] The original binary probably had a rather long orbital period and the initial masses had to be very different, such as 10M? and IM?. The more massive primary evolved all the way to supernova explosion and formation of a neutron star, while the secondary remained on the main sequence, a very ...

    Notes: [Auszug] Human spinal cord specimens were collected post mortem from eight adults (six males, two females; mean age 60 yr, range 48-83 yr) with no evidence of nervous system pathology. All cadavers were stored at 4 C within 2 h of death, and the spinal cords removed within 24 h, a period generally ...

    Notes: [Auszug] Antigen-specific CTL clones were generated from single precursor cells using a standard protocol7. They were characterized in the following manner. (1) They had the surface marker profile of the CTL lineage, that is, Ig, Thy-G, Ly-2+. (2) Proliferation was greatly augmented by stimulation with ...

    Notes: [Auszug] In our laboratory we have examined an SSPE cell line (N-l) obtained by co-cultivation of SSPE brain material with Vero cells9. This cell line shows slowly spreading areas of cell fusion, but does not release infectious virus, although particles can be obtained by procedures which favour cell ...

    Notes: [Auszug] MOST biologists are interested in the adaptations of organisms; very few will find those interests reflected in Conrad's book.
