Notizen: Abstract The effect of the frequency of the applied voltage on the breakdown of semiconductors is investigated. Unlike earlier observations, our experiment yields, in some cases, a breakdown voltage versus frequency curve which is similar in nature to the high-frequency breakdown characteristics in gas devices wherein the breakdown voltage shows a minimum at a certain frequency. A possible theoretical explanation for the above behaviour of semiconductor devices based on dielectric heating is given, which is in fair agreement with the observations.

Notizen: Abstract The solution of a difference equation in the form of an infinite continued fraction is used to obtain a class of exact solutions for the eigenfunctions and eigenvalues of doubly anharmonic oscillators described by potentials of the type (1/2)ω2x2+(1/4)λx4+(1/6)ηx6, n〉0, provided certain constraints on the couplings are satisfied. The class is denumerably infinite but not complete.

Notizen: Abstract The demand for water has been increasing steadily with increases in population and standard of living. The food and energy crises of the Seventies have made water resources development a priority issue in many countries. Agriculture currently accounts for 80 % of all global water consumption but hydroelectric generation does not consume any water. Since irrigation and hydropower generation are compatible uses of water, most recent water developments include both these uses. Quantity of water available to any country is limited, but demands are continually rising. Accordingly, water use has to be made more efficient and options like interregional water transfers have to be explored. The paper outlines the problems and prospects associated with long distance water transfer projects and discusses the latest plans for this type of development in the People's Republic of China.

Notizen: Abstract The first class constraint conditions of relativistic direct interaction dynamics have been solved. Their solution expresses the many-body interactions in terms of the two-body interactions in perturbation expansion. The n-body interaction is of order g smaller than the (n-1)-body interaction. The expressions are considerably simpler than those obtained previously.
