    The first lonization constant of carbonic acid from 25 to 250°C and to 2000 bar (1975)
    Springer
    Journal of solution chemistry 4 (1975), S. 53-70 
    Details
    ISSN: 1572-8927
    Keywords: lonization constant ; carbonic acid
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract The apparent first ionization constant of carbonic acid has been determined by conductivity measurements and found to vary from 4.32×10−7 at 25°C to 1.6×10−8 at 250°C. The pressure effect to 2000 bar has been measured, and the ratio Kp/K1 is 7.3 at 25°C and 19 at 250°C. The standard partial molar volume change for the ionization at 1 bar, $$\Delta \bar V_1^0$$ , increases from −27.6 cm3-mole−1 at 25°C to −88 cm3-mole−1 at 250°C. The volume changes are smaller at higher pressures. A linear correlation between $$\Delta \bar V_1^0$$ and the partial molar compressibility for the ionization reaction has been noted. A similar correlation exists between the partial molar entropy and volume changes for the reaction.

    How safe is safe enough? A psychometric study of attitudes towards technological risks and benefits (1978)
    Springer
    Policy sciences 9 (1978), S. 127-152 
    Details
    ISSN: 1573-0891
    Source: Springer Online Journal Archives 1860-2000
    Topics: Political Science , Economics
    Notes: Abstract One of the fundamental questions addressed by risk-benefit analysis is “How safe is safe enough?” Chauncey Starr has proposed that economic data be used to reveal patterns of acceptable risk-benefit tradeoffs. The present study investigates an alternative technique, in which psychometric procedures were used to elicit quantitative judgments of perceived risk, acceptable risk, and perceived benefit for each of 30 activities and technologies. The participants were seventy-six members of the League of Women Voters. The results indicated little systematic relationship between perceived existing risks and benefits of the 30 risk items. Current risk levels were generally viewed as unacceptably high. When current risk levels were adjusted to what would be considered acceptable risk levels, however, risk was found to correlate with benefit. Nine descriptive attributes of risk were also studied. These nine attributes seemed to tap two basic dimensions of risk. These dimensions proved to be effective predictors of the tradeoff between acceptable risk and perceived benefit. The limitations of the present study and the relationship between this technique and Starr's technique are discussed, along with the implications of the findings for policy decisions.

    Myogenesis and neurogenesis in the chick embryo: A comparative study (1971)
    Springer
    Development genes and evolution 167 (1971), S. 187-198 
    Details
    ISSN: 1432-041X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary An electron microscope study of the comparative development of muscle and nerve tissue in the pectoral and wing regions of the chick embryo has been performed. Neurogenesis in the pectoral region is seen to be about 2 days advanced over that in the wing. Myogenesis proceeds at approximately the same rate in both areas. Myofibril organization and myotube alignment appear to be independent of developing nerve tissue. An incidental finding is that of aggregates of poorly organized myofilaments inserted into otherwise mature myofibres. It is suggested that this may be a method of increase in muscle length.

    Notes: Zusammenfassung Substanzen, welche die thrombin-induzierte Plättchenaggregation hemmen, lassen sich in drei Hauptgruppen aufteilen: 1. membranstabilisierende Steroide, 2. Substanzen, welche die elektrischen Eigenschaften der Membran oder die Permeabilität oder beide beeinflussen, und 3. Substanzen, die eine Erhöhung des intrazellulären cAMP-Spiegels bewirken sollen. Eine Hypothese über die Hemmung der Plättchenaggregation durch Thrombin wird vorgeschlagen.

    Adrenergic innervation of the gut musculature in vertebrates (1969)
    Springer
    Histochemistry and cell biology 17 (1969), S. 263-272 
    Details
    ISSN: 1432-119X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary The adrenergic innervation of the gut musculature has been compared in various vertebrates (two teleost fish, an amphibian, a reptile and a mammal) by the fluorescent histochemical localization of certain monoamines. Very few, if any, adrenergic nerves occur within the longitudinal gut muscle of any of these animals, except for the taenia coli of the guinea-pig caecum. In contrast, the circular smooth muscle coat is supplied by varicose adrenergic nerves. These nerve fibres are particularly numerous in the toad large intestine, guinea-pig caecum, and throughout the eel gut, but are generally sparse or absent from the musculature of the stomach and small intestine of the trout, toad, lizard and guinea-pig. The extent of adrenergic innervation of the muscle has been discussed in relation to the physiology of the different muscle coats and to the general structure of the enteric plexuses in the vertebrate gut.
