1. Net inward charge is calculated for unitary Ia e.p.s.p.s. evoked in spinal motoneurones. Fluctuations in this charge are used to describe the fluctuations in transmission at the Ia synapse. 2. The statistical details of variation in transmission at Ia synapses are largely obscured by noise, arising from spontaneous activity and recording apparatus. 3. A computational procedure is described, which utilized the measured statistical properties of the recording noise, and the measured charge histogram of the evoked e.p.s.p. (with noise) to calculate the variations in charge due to the e.p.s.p. alone. 4. The fluctuation in charge transmission at Ia synapses are, in general, non‐quantal. Nor are they described by binomial or Poisson statistics. 5. It is suggested that the basic mode of transmission at a single terminal is all‐or‐none. The fluctuations result from the combined effect of failures at several terminals arising from a single afferent fibre. This hypothesis is supported by further analysis of these results in a subsequent paper (Edwards, Redman & Walmysley, 1976a).

In order to find the optimum design of structures that have characteristic natural frequency range, a numerical optimization method to solving eigenvalue problems is a widely used approach. However in the most cases, it is difficult to decide the accurate thickness and shape of structures that have allowable natural frequency in design constraints. Parallel analysis algorithm involving the feasible direction optimization method and Rayleigh-Ritz eigenvalue solving method is developed.The method is implemented by using finite element method. It calculates the optimal thickness and the thickness ratio of individual elements of the 2-D plane element through a parallel algorithm method which satisfy the design constraint of natural frequency. As a result this method of optimization for natural frequency by using finite element method can determine the optimal size or its ratio of geometrically complicated shape and large scale structure.

-The flash point the lowest temperature at which the concentration of vapor of the substance in the air reaches the lower flammability limit(LFL), and is one of the most important physical properties used to determine the potential for fire and explosion hazards of industrial materials. The most published flash point data was for pure components and the flash points of the binary solutions that have flammable components, appear to be scarce in the literature. In the present study, the flash points of tert-pentanol+n-decane system were measured by Tag open-cup tester. The measured data were compared with the values calculated by the Raoult's law and the optimization methods based on the Wilson and NRTL equations. The calculated values by optimization methods were found to be better than those based on the Raoult's law.
