    The method of lines for Poisson's equation with nonlinear or free boundary conditions (1978)

    Notes: Summary The method of lines is used to solve Poisson's equation on an irregular domain with nonlinear or free boundary conditions. The partial differential equation is approximated by a system of second order ordinary differential equations subject to multi-point boundary conditions. The system is solved with an SOR iteration which employs invariant imbedding for each one dimensional problem. An application of the method to a boundary control problem and to a free surface problem arising in electrochemical machining is described. Finally, some theoretical convergence results are presented for a model problem with radiative boundary conditions on fixed boundaries.

    A note on the approximation of mildly nonlinear Dirichlet problems by finite differences (1979)
    Springer
    Numerische Mathematik 33 (1979), S. 303-313

    Notes: Summary In [9], Simpson proved some theorems concerning the approximation of mildly nonlinear Dirichlet problems −Δu=f (x, u) inD, u=0 on ∂D by finite differences. The assumptionsf(x, 0)≧0 andf u(x, u)〉0 in [9] have turned out to be unnecessarily restrictive and are eliminated in this paper. On the other hand, we considered it necessary to make the smoothness conditions forD slightly more stringent irrespective of the conditions imposed onf.

    Mating stimulant pheromone and cuticular lipid constituents ofFannia femoralis (Stein) (Diptera: Muscidae) (1978)
    Springer
    Journal of chemical ecology 4 (1978), S. 83-93 
    Details
    ISSN: 1573-1561
    Keywords: Fannia femoralis (Stein) ; pheromone ; mating stimulant pheromone ; (Z)-11-hentriacontene ; cuticular lipid ; fly
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract The cuticular lipids of male and femaleFannia femoralis were similar for recently emerged insects but soon began to develop chromatographic patterns characteristic of each sex. Mature females contained more C31 and C33 monoolefin in the cuticular lipid than males. Also, the double bonds in the monoolefins of the female lipid were situated predominantly at the eleventh and thirteenth carbons, while most of those from the males were centrally located in the molecule or at the ninth carbon. The female C31 monoolefin stimulated copulation by the males, but more mating activity occurred when the saturated hydrocarbons present in the female cuticular lipids were added. The synthetic monoolefin most active as a mating stimulant pheromone was (Z)-11-hentriacontene, but the addition of female alkanes or of syntheticn-alkanes to (Z)-11-hentriacontene increased the activity of the synthetic pheromone.

    Mating stimulant pheromone and cuticular lipid constituents ofFannia pusio (Wiedemann) (Diptera: Muscidae) (1978)
    Springer
    Journal of chemical ecology 4 (1978), S. 73-81 
    Details
    ISSN: 1573-1561
    Keywords: Fannia pusio (Wiedemann) ; pheromone ; mating stimulant pheromone ; (Z)-11-hentriacontene ; cuticular lipid ; fly

    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Chromatograms of the cuticular lipids washed from newly emerged male and femaleFannia pusio were nearly identical. By the time the flies were 1 day old, the chromatographic profiles for the sexes were different. Mature females contained more C31- and C33-hydrocarbons than the males. The double bonds of the female monoolefins were mostly at the eleventh and thirteenth carbons, but those of the males were predominantly at the ninth carbon. Most active in stimulating copulation by males were the unbranched monoolefins with 31 and 33 carbons from the females. When they were synthesized and tested, the most active compound was (Z)-11-hentriacontene.
