    A shape-optimization technique for the capillary surface problem (1990)
    Springer
    Numerische Mathematik 58 (1990), S. 737-757 
    Details
    ISSN: 0945-3245
    Schlagwort(e): AMOS(MOS): 49A22 ; 58E12 ; 65M60 ; CR: G1.8.G1.6
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Mathematik
    Notizen: Summary The problem of the construction of an equilibrium surface taking the surface tension into account leads to “Laplace-Young” equation which is a nonlinear elliptic free-boundary problem. In contrast to Orr et al. where an iterative technique is used for direct solution of the equation for problems with simple geometry, we propose here an alternative approach based on shape optimization techniques. The shape of the domain of the liquid is varied to attain the optimality condition. Using optimal control theory to derive expressions for the gradient, a numerical scheme is proposed and simple model problems are solved to validate the scheme.

    Zerumbone: a potential fungitoxic agent isolated from Zingiber cassumunar Roxb. (1992)
    Springer
    Mycopathologia 120 (1992), S. 155-159 
    Details
    ISSN: 1573-0832
    Schlagwort(e): Fungitoxicity ; zerumbone ; Zingiber cassumunar
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie , Medizin
    Notizen: Abstract The rhizomes of Zingiber cassumunar exhibited strong fungitoxic action against Rhizoctonia solani, the damping-off pathogen. On chemical and spectral investigations, the antifungal compound was found to be zerumbone — a sesquiterpene. Its minimum effective dose against R. solani was 1000 ppm, much lower than some commercial fungicides. Zerumbone had fungistatic activity, a narrow fungitoxic spectrum and was not phytotoxic. Moreover, when used as a seed treatment, zerumbone could control damping-off disease of Phaseolus aureus caused by Rhizoctonia solani by 85.7%.

    Fungitoxicity of some higher plants againstRhizoctonia solani (1983)
    Springer
    Plant and soil 72 (1983), S. 91-94 
    Details
    ISSN: 1573-5036
    Schlagwort(e): Anti-fungal activity ; Chenopodium ambrosioides ; Fungitoxicity ; Rhizoctonia solani
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Land- und Forstwirtschaft, Gartenbau, Fischereiwirtschaft, Hauswirtschaft
    Notizen: Summary Leaves ofChenopodium ambrosioides exhibited strong fungitoxicity against the mycelial growth ofRhizoctonia solani causing damping off diseases of some seedlings. Minimum inhibitory concentration of the fungitoxic constituent isolated in form of essential oil, was found to be 1000 ppm at which it was fungicidal in nature. It exhibited broad range of antifungal activity and did not show any phytotoxicity on the germination and seedling growth ofPhaseolus aureus.
