    Notes: A fairly realistic nonlinear model of a water reservoir system with multiple uses has been developed based on available data, and the optimum of the system based on the developed model has been determined by the combined use of dynamic programming and the pattern search techniques. Both the simplex search and the Hooke and Jeeves pattern search have been used. The approach in modeling and optimization can treat complex inequality constraints. The benefits or losses resulting from four purposes or uses of water, namely, urban water supply, hydroelectric power generation, irrigation, and recreation, are taken into account in the profit function. Other uses such as flood control, navigation, and fish and wildlife enhancement are considered indirectly by the use of inequality constraints. It appears that the approach developed in this work can treat a water resource allocation problem involving complex inequality constraints.

    Notes: One of the problems of a theory of integration consists in the difficulty to define ‘integration’ itself. The theory of international trade can hardly provide such a definition, for the problem of integration are related to the various fields of theory. The author defines integration as the merger of two or more national economies. In such an integrated economy some of the national public offices must be joint together in order to solve the problems of the whole integrated area. This is the reason why the author prefers an ‘institutional’ to a ‘functional’ solution.The way the economies are integrated depends on their structure. The present-day problem is the integration of ‘mixed’ economies of the western Europe type. The most important requirements of a total integration are: (1) giving up the internal border-lines, (2) centralization of the national policies and erecting a joint legal constitution, (3) assimiliation of the national economic structures.The examination of the political and economic consequences of integration shows that uniting several economies into one is possible without complete political union. The process of economic integration is autonomous and can be pushed forward isolatedly. But it is not possible as yet to give exact details about the economic effects of integration.

    The Fine Structure of the Flagellum and Kinetoplast-Chondriome of Trypanosoma (Schizotrypanum) cruzi in Tissue Culture (1968)

    Notes: SYNOPSIS. Trypanosoma cruzi in tissue cultures was studied with the electron microscope after double fixation in glutaraldehyde and osmium tetroxide, and embedding in Epon. Previous findings on its fine structure were confirmed, and some new structures were found in the flagellum and kinetoplast-chondriome.In the flagellum, an intraflagellar body was found, similar to that observed in other trypanosomes, beginning at the base of the flagellum and running along the axial fibre bundle thruout its length. The axial fibre bundle is formed by interconnecting tubules, the outer ones apparently smooth, the inner ones with a helical substructure. Lateral extensions from the outer tubules in the flagellar bundle seem to enter the intraflagellar body.The kinetopiast in the leishmania bodies has the same electrondense structure described before. In the trypanosome form it has assumed a large spherical shape, in which the formerly short, compressed fibres have grown in length, are more dispersed and have an irregular shape. They are oriented in the direction of the body's length in parallel array. The whole formation is continuous with a long mitochondrion which begins in the region of the nucleus and extends up almost to the tip of the trypanosome. The matrix of the kinetoplast in these forms is electron-transparent; the matrix of the mitochondria is rather dense.In a few extracellular trypanosomes, a special structure was found in which the kinetoplast is composed of electron-transparent formations, arranged in orderly horizontal lines quite similar to the mitochondrial cristae of the parasite. The significance of this structure is uncertain.
