    Notes: [Auszug] We are examining a fundamentally different procedure in which reactions are carried out in solution and the protected peptide is then adsorbed on an ion-exchanger while the excess of acylating agent and the co -products are washed away. For this purpose, a weakly basic group has been incorporated ...

    Oscillating reactions in open systems (1969)
    Springer
    Bulletin of mathematical biology 31 (1969), S. 441-452

    Notes: Abstract The probable existence of oscillating chemical reactions has been attracting some interest in recent years for their possible role in explaining certain biological phenomena. Perhaps the simplest model of oscillating reactions is that of Lotka (1910), which consists of a chain of autocatalytic reactions. Two “reactor systems” in which such a chain of reactions could take place are considered in this work and are called homogeneous and compartmental models, respectively. The differential equations governing the temporal behavior of the reacting species are solved on an analog computer, and the conditions under which sustained oscillations occur are obtained and discussed. Comparisons of the solution obtained in the two models are discussed.

    Minimizing the natural fuel requirement for nuclear reactor power systems: A nonstandard optimal control problem (1968)
    Springer
    Journal of optimization theory and applications 2 (1968), S. 138-154

    Notes: Abstract A class of model problems in nuclear reactor economics is defined and shown to be equivalent to a linear optimal control problem to which present versions of the maximum principle apparently cannot be applied. It is shown that the search for an optimal control can be restricted tocontrols of maximum fuel utilization (Comfu), and that theComfu's are in a one-to-one correspondence with the functions which satisfy certain inequalities and are solutions of a nonlinear Volterra integral equation containing the value of the cost functional as a parameter. In the general case, one can establish an iterative procedure, involving solution of the integral equation at each iteration, for approximating the optimalComfu. For some important special cases, a point on the solution corresponding to the optimalComfu is knowna priori, and thus the optimalComfu can be obtained by solving the integral equation only once. Some possible generalizations of the original economic model are also discussed.
