θ_1 and θ_2 are symmetrical to the θ_0. The extreme values of θ are 40.4° and 90° ( forβ, 49.6° and 0° ) The faults closing to or exceeding the extremum of θ are able to be earthquake rupture faults.

Thus, the Cv of LAI is regarded as the extremum of that of throughfall.

The global extremum (minimum) of this dependence, which was accepted as the goal function, was used as a criterion for designing the algorithm optimizing the gripper position on the load axis upon stabilizing the angular motion of the module.

The calculated extremum is used in the loop of adaptive adjustment of the gripper parameter, which prevents resonance swinging of the flexible load transported to the place of installation.

Computer experiment demonstrated, however, that the iterative procedure stabilized after several steps, although the global extremum was not necessarily attained.

An effective method for finding the global extremum in identifying a logical-probabilistic risk model within reasonable computation time is developed.

The three-dimensional properties of des-pentapeptide insulin (DPI) in solution have been studied by several methods, in view of the obvious fact that such knowledge would have much to bear on the structure of the binding site of insulin.(1) The molecular weight of DPI was studied by the gel filtration method. The results demonstrate that DPI does not exhibit self-association behaviour, and exists as monomer under the experimental conditions.

The three-dimensional properties of des-pentapeptide insulin (DPI) in solution have been studied by several methods, in view of the obvious fact that such knowledge would have much to bear on the structure of the binding site of insulin.(1) The molecular weight of DPI was studied by the gel filtration method. The results demonstrate that DPI does not exhibit self-association behaviour, and exists as monomer under the experimental conditions. This enables us to deduce that insulin binds its receptor in the monomer form; its action unit is the monomer.(2) The pH difference spectra, denaturation difference spectra, and temperature effect curves were examined. The results indicate that all three tyrosyl side chains of DPI are unmasked and situated on the surface of the molecule.(3) The UV CD curves of DPI were also studied. The far UV CD curve of DPI at pH 7.0 is similar to that of insulin, except that the negative value for [θ]_(220) decreases. This probably demonstrates that the peptide backbone conformation of DPI is very similar to that of insulin except that it is slightly extended for the former. The near UV CD curve for DPI differs from that for insulin and has an extremum at 266 nm and a low negative value of [θ]. The assignment of this extremum to Phe and/or -S-S- was discussed.Taking into consideration the results given in proceeding papers it may be concluded that the results of conformation research support our previous working hypothesis that the hydrophobic surface in between the two monomers that make up dimeric insulin constitutes a part of the receptor-binding site of insulin.

This paper describes the characteristics of the precursors of sudden changes and the regularity of their distribution in accordance with time and pregnant shock locality. We adopted the method of extremum coincidence and the accumulated data of precursor patterns, trying to make a certain number of experimental predictions about a part of the strong earthquakes in the world. The results obtained may be encourraging for further investigation.

The present paper is devoted to the search for variational principles for the direct aerodynamic problem of channels and aerofoil cascades (with prescribed distributed mass injection or/and suction along the profile contours for blade cooling or boundary layer control) on an arbitrary stream sheet of revolution and aimed mainly at providing a rigkms and sound theoretical basis for introducing and widely applying the finite element method to computational aerodynamics of turbomachines. Three generalized variational principles (among which two are for homoentropic flow, and the other for nonhomoentropic flow) are developed first, and then from them three families of variational principles are derived respectively by means of successive transformations. Furthermore, for homoentropic subsonic flows a pair of dual extremum principles are also shown to exist.Special attention is payed to taking full advantage of 2 effective means: "natural boundary conditions" and "artificial boundaries", in order to greatly simplify the numerical treatment of various boundary conditions characterizing the complexitg of the cascade problem. So in all variational principles all boundary conditions have been converted to natural ones.The variational principles presented here can be used to advantage as basis also for variational-finite difference method and for various direct variational methods (e.g. Ritz's method, Kantorovich's method etc.).
