Influence of the Initiator

In the general case, a buoyant jet has an initial momentum. In the region close to discharge, momentum forces dominate the flow, so it behaves like a nonbuoyant jet. There is an intermediate region where the influence of the initial momentum forces becomes smaller and smaller. In the final region, the buoyancy forces completely dominate the flow and it behaves like a plume. When the jet is supplied at an angle to the vertical direction, it is turned upward by the buoyancy forces and behaves virtually like a vertical buoyant jet in a far field. A negative buoyant jet continuously loses momentum due the opposite direction of buoyancy forces to the supply air momentum and eventually turns downward. 

The influence of selectivity in the initiation, termination or chain transfer steps on the distribution of monomer units within the copolymer chain is usually neglected. Galbraith et a .u provided the first detailed analysis of these factors. They applied Monte Carlo simulation to examine the influence of the initiation and termination steps on the compositional heterogeneity and molecular weight distribution of binary and ternary copolymers. Spurting et a/.250 extended this...

Monitoring the pH value during the preparation of gold sol, which leads to the below reported results, it has been observed that pH moves from ca. 3.2, before NaBH4 addition, to ca. 6.9, after NaBH4 addition. In this section a discussion of the influence of the initial pH value on the properties of the colloidal dispersion stabilized by a large amount (PVA/Au = 0.67) or a low amount (PVA/ Au = 0.05) of stabilizer is presented. Proper amounts of HCl or NaOH were used to produce the reported pH values.

Fig. 7-13. The seasonal variation of temperature in the Southern Hemisphere plotted as solid lines for DAV10, with permanent ice at high latitudes, and as dashed lines for the reference results, DAV09. The new calculations are started with the same initial values. It takes a few years for the influence of the initial values to die out.

Table 3.2 shows the influence of the initial PEI concentration on the resulting particle size distribution. Both the size and the number of PEI domains increased in the sea-island morphology, whereas the size of thermoset nodule decreased and the number of nodules increased in the nodular morphology as the initial PEI concentration was increased. 

Belayev and Belayeva [54] studied the influence of the initial temperature on the rate of burning of mercury fulminate, pressed into pellets. The results are shown in Fig. 34. A 100 °C temperature increase in the mercury fulminate accelerated the rate of burning approximately 1.7 times. The authors also investigated the rate of burning of mercury fulminate at various temperatures, and expressed this relationship by the following equations ... 

The influence of the initial temperature of the mixture on the combustion rate depends on the change in the combustion temperature and the heat of activation of the reaction occurring in the flame if the rate of heat release depends on the temperature according to the Arrhenius law,... 

The solution of the problem (8)-(10) is some approximation to the solution of the original problem (1)—(3) for sufficiently large times when the influence of the initial conditions disappears. To find the degree of correspondence between the solutions we performed numerical calculations on the determination of the non-steady velocity and temperature distribution in the combustion wave using direct and approximate methods. 

Polyakov and co-workers [5] made an especially detailed study of the influence of the initial pressure and diameter of the vessel on the formation of nitric oxide in an explosion. They came to the conclusion that combustion takes place according to a branching chain mechanism and that the breaking off of the chains in the volume, i.e., the reaction of the active centers with...

If a solvent effect is present, one would expect an influence of the initial solvent/monomer ratio although weak. This was indeed found by Goeldi and Elias (8). The effect of monomer conversion is apparently too small to be detected by the present accuracy of tacticity determinations (8, 23).
