    Notes: [Auszug] DR. BOWDEN and his collaborators1 in their investigations on the mechanism of metallic friction need have little doubt that, under many of the conditions of load and speed used in practice, the local temperatures reach a high value. Very high local temperatures are attained in ...

    Notes: [Auszug] ONE of the chief difficulties in the interpretation of the analogies between the biological activity of a drug and its behaviour in synthetic systems arises from the ambiguity of toxicological data, which may generally be correlated with solubility in the cell lipoids (Overton-Meyer), adsorption at ...

    Permeability of Insect Cuticle (1940)
    [s.l.] : Nature Publishing Group
    Nature 145 (1940), S. 462-463 
    Details
    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] ONE of the major problems in research on insecticidal action concerns the correlation of the toxicity of an insecticide with its chemical and physical properties. Very little progress has hitherto been made when relatively non-toxic carriers have been used. This is mainly due to the fact that ...

    Principles of Insecticidal Bio-Assay (1943)
    [s.l.] : Nature Publishing Group
    Nature 152 (1943), S. 400-404 
    Details
    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] THE need for standardized methods of testing insecticides has become an important factor in insecticidal research, especially where routine examination of new materials is desirable. Chemical assay may provide an index of the potential toxicity of an insecticide, but evidence has been provided ...

    Notes: [Auszug] IN a recent communication1, I provided evidence to show that the permeability of the outer ‘lipoid layer’ of insect cuticle to feebly dissociating substances of high dielectric constant may be greatly increased by relatively apolar substances of low dielectric constant. Since ...
