    Activity of quassinoids as antifeedants against aphids (1989)
    Springer
    Journal of chemical ecology 15 (1989), S. 993-998 
    Details
    ISSN: 1573-1561
    Keywords: Antifeedant ; Myzus persicae ; Hemiptera ; Aphididae ; quassinoid ; Simaroubaceae
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract A series of quassinoids was tested for antifeedant activity against the aphidMyzus persicae (Hemiptera, Aphididae). Isobrucein B, brucein B and C, glaucarubinone, and quassin decreased feeding at concentrations down to 0.05% and isobrucein A was effective at 0.01%. Only quassin showed no phytotoxic effects and is therefore the most promising compound for further development.

    Antifeedant activity of quassinoids (1984)
    Springer
    Journal of chemical ecology 10 (1984), S. 1497-1507 
    Details
    ISSN: 1573-1561
    Keywords: Antifeedant ; Mexican bean beetle ; Epilachna varivestis ; Coleoptera ; Coccinellidae ; southern armyworm ; Spodoptera eridania ; Lipidoptera ; Noctuidae ; quassinoids ; Simaroubaceae

    Notes: Abstract The antifeedant activity of 13 quassinoids of different structural types has been studied against the Mexican bean beetle (Epilachna varivestis Mulsant) 4th instar larvae and the southern armyworm (Spodoptera eridania Crawer) 5th instar larvae. All quassinoids tested displayed significant activity against the Mexican bean beetle and, thus, do not reveal a simple structure-activity relationship. Five quassinoids were active against the southern armyworm. Interestingly, four of these-bruceantin (I), glaucarubinone (VI), isobruceine A (VIII), and simalikalactone D (XI)-possess the required structural features for antineoplastic activity. The noncytotoxic quassin (X) is an exception; it is active against both pests.

    An experimental facility for determination of steady flame spread rate of materials employing the Quasi-stationary flame front technique (1992)
    New York, NY [u.a.] : Wiley-Blackwell
    Fire and Materials 16 (1992), S. 169-180

    ISSN: 0308-0501
    Keywords: Chemistry ; Polymer and Materials Science

    Notes: An experimental facility based on the Quasi-stationary Flame Front Technique for determination of steady flame spread rate of materials at discrete levels of external radiant heat flux was developed. The method employs an external radiant heat source in front of which an element of a specimen of the material is positioned at a location corresponding to the desired level of external radiant heat flux. A specimen movement assembly, which can be operated manually, was designed for moving the specimen towards the stationary external radiant heat source such that the flame front could be maintained quasi-stationary. The experimental technique employed is simple in operation yet is capable of yielding reliable flame fornt displacement-time data. In the paper the design considerations of the experimental facility, details of its components, calibration and typical experimental results obtained are presented.

    Fire and rice husk particleboard (1994)

    Notes: Experimental investigations were made to assess the fire behaviour of rice husk particleboard, a potential substitute for wood particleboards. Releveant fire properties, namely non-combustibility, ignitability, fire propagation index, surface spread of flame classification, specific optical density of smoke generated, flammability and flame penetration were determined in accordance with existing standard methods. In this paper the salient results obtained are discussed.

    An appraisal of standard methods for determination of flame spread behaviour of materials (1992)

    Notes: Salient features of the standard apparatuses and the methodology adopted by various countries for determination of flame spread behaviour of materials are analysed and discussed with a view to obtain a perspective of the performance of these apparatuses. This study was undertaken to investigate the possible reasons for anamolies in the results obtained using these apparatuses. A need is established for development of a new technique for direct determination of flame spread rate of materials under steady-state conditions which has the potential of overcoming the inherent limitations of the existing apparatuses.
