    Ion-solvent interactions: Conductance behavior of NaAlBu4 and Bu4NAlBu4 in benzene and tetrahydrofuran (1974)
    Springer
    Journal of solution chemistry 3 (1974), S. 83-89 
    Details
    ISSN: 1572-8927
    Keywords: Conductance ; sodium tetrabutylaluminate ; tetrabutylammonium tetrabutylaluminate ; tetrahydrofuran ; benzene ; ion pairs ; ion aggregates

    Topics: Chemistry and Pharmacology
    Notes: Abstract Conductance measurements are reported for NaAlBu 4 and Bu 4 NAlBu 4 in benzene and in tetrahydrofuran (THF) from a concentration of approximately 5×10−3 M to the fused state for each salt. This is the first reported study where a comparison of a salt with a small cation is made with one having a large cation in a noncomplexing solvent (benzene) and a complexing solvent (THF). The similarity in conductance behavior in THF and the differences in benzene are considered in terms of ion-ion and ion-solvent interactions.

    Survival of Diplectrona modesta banks (Trichoptera : Hydropsychidae) during short periods of desiccation (1981)
    Springer
    Hydrobiologia 77 (1981), S. 61-63 
    Details
    ISSN: 1573-5117
    Keywords: Diplectrona modesta ; Trichoptera ; Hydropsychidae ; intermittent stream ; desiccation survival

    Topics: Biology
    Notes: Abstract Larvae of the caddisfly, Diplectrona modesta (Hydropsychidae), were found to be permanent inhabitants of a small, intermittent, headwater stream in southern Ontario. They survived desiccation for at least four weeks in summer. A laboratory experiment gave a mean survivorship of 50% after 30 days without water in stream gravel and stones after the larvae had been permitted to construct their shelters. Survivors were those that constructed their tubes deep in the substrate.
