Covering power, definition

Figure 17-46 shows such a performance curve for the collection of coal fly ash by a pilot-plant venturi scrubber (Raben "Use of Scrubbers for Control of Emissions from Power Boilers, United States-U.S.S.R. Symposium on Control of Fine-Particulate Emissions from Industrial Sources, San Francisco, 1974). The scatter in the data reflects not merely experimental errors but actual variations in the particle-size characteristics of the dust. Because the characteristics of an industrial dust vary with time, the scrubber performance curve necessarily must represent an average material, and the scatter in the data is frequently greater than is shown in Fig. 17-46. For best definition, the curve should cover as wide a range of contacting power as possible. Obtaining the data thus requires pilot-plant equipment with the flexibility to operate over a wide range of conditions. Because scrubber performance is not greatly affected by the size of the unit, it is feasible to conduct the tests with a unit handling no more than 170 m3/h (100 ftVmin) of gas.

According to the appeals court, The primary legal issue is whether the Legislature has completely preempted the field of regulation of handgun sales. In the absence of state preemption, every municipality is authorized by the California Constitution to exercise its police power to deal with local situations. The idea of preemption is that a lower jurisdiction (such as a city) cannot make a law that deals with a matter that a higher jurisdiction (such as the state) has already definitively covered. The lower court found that the local ordinance was not preempted. 

The idea of solvent polarity refers not to bonds, nor to molecules, but to the solvent as an assembly of molecules. Qualitatively, polar solvents promote the separation of solute moieties with unlike charges and they make it possible for solute moieties with like charges to approach each other more closely. Polarity affects the solvent s overall solvation capability (solvation power) for solutes. The polarity depends on the action of all possible, nonspecific and specific, intermolecular interactions between solute ions or molecules and solvent molecules. It covers electrostatic, directional, inductive, dispersion, and charge-transfer forces, as well as hydrogen-bonding forces, but excludes interactions leading to definite chemical alterations of the ions or molecules of the solute. 

We must specify what is a secure revocation scheme, i.e. describe the adversary s power and what is considered a successful break. We provide a sufficient condition for a Subset-Cover revocation scheme A to be secure. We start by stating the assumptions on the security of the encryption schemes E and F. All security definitions given below refer to an adversary whose challenge is of the form distinguish between two cases i and ii . 

Because comprehensive literature [1-8] covering various aspects of organo-lithium chemistry has recently become available, the purpose of fhis chapter is to highlight powerful synthetic tools involving organohfhium compounds. The definition of organohfhium is here limited to those compounds in which fhere is a clear C-Li bond compounds with enolate or ynolate structures or wifh heteroatom (Y)-Li bonds, etc., have been excluded. 

The collector electric efficiency is the ratio between the electrical power collected at the edge of the LSC and the power from the same photovoltaic material, when covering the surface of the LSC. For practical purpose a set of definitions recently proposed by Friedman28 are quite useful ... 

None of these methods is utterly satisfactory. The use of alkali-metal solutions in liq NH3 allows intercalation from Li to Cs to be covered. It can readily be used to prepare nonstoichiometric phases but the method presents experimental difficulties. Ammonia is often cointercalated, which favors the formation of trigonal prismatic intercalates owing to the preference of the NH3 for this type of site. On the other hand, the solvation of the A ions by NH3 may determine the composition of the final product in relation to the formation of stable complex species, with a definite formulation, between the slabs of the host. The thermal treatment necessary to remove the NHj may also lead to different structures than those formed at RT it certainly plays a role concerning the phase limits. Alkali-metal solutions in liq NH3 are powerful reducing solutions, and in the case of tellurides, or even for some selenides or sulfides, a reduction of the host structure can occur. 

It will be observed that none of these events did endanger reactor safety. On the other hand one (no.40) definitely compromised any hope to cover the plant operating costs, for the repair could not restore hot irradiated fuel storage capacity and compelled the operator thereafter to wait for the decay power to subside before unloading the core, meaning long outages. 

The decree of the 31 December 1998 finalized the immediate and definitive shutdown of Creys nuclear power station and authorized unloading of the fuel. It also covers sodium removal and storage operations and the dismantling of the non-nuclear installations within the framework of a safety report and general rules for monitoring and maintenance approved by the DSIN (French Nuclear Installations Safety Authority).
