    Notes: [Auszug] The solvent which has been found most useful is high viscosity (between 25 and 300 centipoise) paraffin, carefully freed from aromatics and other impurities by separation on a silica column and then thoroughly degassed by successive freezing and evacuation. No free radicals were detectable unless ...

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] Recently, during the course of marrow transplantation experiments in irradiated dogs, search was made for a biological cell marker characteristic of the donor which would be identifiable in the host. The possibility of a sex difference in dogs' blood analogous to that seen in man was considered and ...

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] This scheme does not give a satisfactory account of the principal features of atom recombination reactions which have been observed experimentally. The most accurate data are those derived from flash photolysis studies of halogen atom recombinations which have established that: (a) rates of ...

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] The stationary liquid phase normally used in gas chromatography has a low volatility relative to the compounds being separated. With the circular apparatus, the liquid need not have a low volatility. Fig. 2 shows the record for separation at room temperature of acetone, boiling point 56 -2 C, and ...

    Evidence for the Conversion of Quinic Acid to Shikimic Acid in Roses (1959)
    [s.l.] : Nature Publishing Group
    Nature 183 (1959), S. 326-326

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] In certain micro-organisms, shikimic acid has been demonstrated to be in the direct path to aromatic ring biosynthesis5. Microbial response to exogenous quinic acid has been reported in secondary mutants of Aerobacter which grew well when supplied with quinic acid5. Similar results have been ...

    Notes: [Auszug] Carter1 suggested that the measure of productivity be the number of mice born and weaned, divided by the number of prenatal days. This index will be less than 1-0, occasionally less than 0-1, and to be useful it will contain two significant figures. Later it was suggested2 that the reciprocal of ...

    Notes: [Auszug] THE absorption spectrum of chlorine monoxide was first detected in the photochemical reaction between chlorine and oxygen1-2 and all direct studies of its reactions have so far been carried out on this system. The mechanisms of these reactions have been thoroughly elucidated, but3 it has been ...

    Notes: [Auszug] Several samples of sodium deoxyribonucleate (DNA) prepared by different workers and from different sources were precipitated from aqueous solution by the gradual addition of 0-5 N hydrochloric acid and the turbidity of the solutions followed (Fig. 1). Within limits the DNA concentration did not ...
