SC EDC (87C51FC) operates under the conditions of 32 kb program internal memory As to expand the internal memory, additional external IC WM of 2 kb memory is used. [Pg.651]

Note 1. The heat developed by the reaction is just enough to cause gentle refluxing, provided that the mixture is not stirred too vigorously. If refluxing stops during the addition, external heating must be applied. [Pg.145]

Once a fusion reaction has begun in a confined plasma, it is planned to sustain it by using the hot, charged-particle reaction products, eg, alpha particles in the case of D—T fusion, to heat other, colder fuel particles to the reaction temperature. If no additional external heat input is required to sustain the reaction, the plasma is said to have reached the ignition condition. Achieving ignition is another primary goal of fusion research. [Pg.151]

Process systems are broadly categorized as self-regulatory and nonself-regulatory. The former is one in which a change in an external condition can cause the system to move from an initial steady state to another steady state without additional external intervention. The latter, a nonself-regulatory process system, does not achieve another steady state without additional control action once the first external change occurs. [Pg.60]

In poorly conducting media or soils, however, the low driving voltage can limit the use of galvanic anodes. Raising the current delivery, which becomes necessary in service, is only practically possible with the help of an additional external voltage. In special cases this is used if an installed galvanic system is overstretched or if the reaction products take over additional functions (see Section 7.1). [Pg.205]

Certain devices may be obtained which are factory-sealed —that is, interconnecting wiring is sealed by the manufacturer where it enters/exits enclosures. These devices do not require an additional (external) seal, and often can be utilized to advantage in lessening installation time and reducing space requirements (for an external seal). [Pg.540]

Furthermore, we introduce additionally external forces f xj) and fluctuating forces and assume -correlations for the fluctuations ... [Pg.862]

Stack emissions can include particulates as well as dense gases (heavier tlian air, e.g., chlorine). These are subjected to a downwash settling tlirough tlie alinosphere due to tlie action of gravity. For tlie particles, especially large ones, an additional external force term must be included in the analysis. [Pg.376]

Notice that in Table 5.2 all the deviations are negative the observed molar volume is less than that predicted by the ideal gas law. This effect can be attributed to attractive forces between gas particles. These forces tend to pull the particles toward one another reducing the space between them. As a result, the particles are crowded into a smaller volume, just as if an additional external pressure were applied. The observed molar volume, Vm, becomes less than V , and the deviation from ideality is negative ... [Pg.123]

There is difficulty in defining the absolute mobilities of the constituent ions in a molten salt, since it does not contain fixed particles that could serve as a coordinate reference. Experimental means for measuring external transport numbers or external mobilities are scarce, although the zone electromigration method (layer method) and the improved Hittorf method may be used. In addition, external mobilities in molten salts cannot be easily calculated, even from molecular dynamics simulation. [Pg.125]

External review is of major importance in ensuring the outcome and reportability of LSMBS study results. Additional experts have the opportunity to review the data and results just after their generation, at a point where corrections can be easily proposed and made. In addition, external review aids in achieving consistency in the results reported by different laboratories. Finally, external review provides feedback for optimization of the analytical and instrumental parameters at each laboratory. [Pg.245]

The conventional photolysis apparatus consists of a concentrically arranged immersion well for the lamp, which is surrounded by a cooling jacket, which is itself surrounded by the reaction vessel. If this last compartment is used for the filter solution an additional external flask for the reaction mixture has to be used. There are also photochemical reactors wherein the lamps are arranged externally around the reaction flask. [Pg.79]

When an atomic ion is under the influence of an additional external spin-independent potential vext(f), produced for instance by a polarizable environment, the effective energy of the atomic ion becomes ... [Pg.99]

Besides the nuclear attraction, fextix) could also include additional external fields, if present. j/(x) denotes the fermion field operator of the interacting, inhomogeneous system characterized by if, p x ) is the corresponding fermion four current operator. [Pg.231]

During the addition external heating may be discontinued and the internal temperature regulated by the rate of addition. [Pg.27]

The second term in Eq. (8) denotes the sum of the relativistic one-electron Dirac Hamiltonians of moving electrons in some additional external electromagnetic field ( Aext),... [Pg.181]

The method uses Leung s method (equation (6.5) or (6.9)), but with a modified value of the heat release rate per unit mass, q, to account for the additional external heat input. This modified value of q is given by ... [Pg.176]

The third method uses two weirs, eliminating need for an interface float. Interface level is controlled by height of the external water weir relative to the oil weir or oudet height This is similar to the bucket and weir design of horizontal separators. Advantage of this system is that it eliminates the interface level control. The disadvantage is that it requires additional external piping and space. [Pg.98]

All calculations presented in the following chapters are restricted to dust formation in C-stars and are performed under the assumption of chemical equilibrium for the molecular reactions among the various chemical elements. The element abundances have to be specified as additional external parameters. For dust driven winds the amount of condensed material determines the velocity field and in particular the terminal velocity of the wind. For this reason, the abundances of the dust forming elements and the terminal velocity of the wind are coupled very closely. For the case of M-stars similar calculations have been performed by Kozasa et al. (1984) considering formation of MgSi03 grains. [Pg.170]

Hydrogen can be incorporated into silicates in the form of water, H2 molecules, Hatoms, H+, OH", and other ways. Since oxygen is one component of a silicate, both the oxygen and hydrogen potentials (mo2,Hh) must be defined in order to fix the thermodynamic state of the hydrogen containing silicates. Furthermore, the proton activity must be defined by an additional external (electrode) or internal redox buffer (e.g., Fe2+/Fe3+). [Pg.364]
