Efficiency local

Provide and maintain efficient local exhaust ventilation, if enclosed plant cannot be used. 

Efficiency, local The efficiency of a given point on a filter at set operating conditions. 

It is essential that the stirring should be most efficient, so that when the mixture becomes thick the dichromate will be evenly distributed throughout the liquid, as rapidly as it is added. If the stirring is not efficient, local reactions of extreme violence (in certain cases leading to conflagration) will occur. An iron stirrer may be employed in the oxidation reaction, but not in the purification. 

For molecular systems in the vacuum, exact analytical derivatives of the total energy with respect to the nuclear coordinates are available [22] and lead to very efficient local optimization methods [23], The situation is more involved for solvated systems modelled within the implicit solvent framework. The total energy indeed contains reaction field contributions of the form ER(p,p ), which are not calculated analytically, but are replaced by numerical approximations Efp(p,p ), as described in Section 1.2.5. We assume from now on that both the interface Y and the charge distributions p and p depend on n real parameters (A, , A ). In the geometry optimization problem, the A, are the cartesian coordinates of the nuclei. There are several nonequivalent ways to construct approximations of the derivatives of the reaction field energy with respect to the parameters (A1 , A ) ... 

The oxidation of carbon can also be catalyzed. Two fundamentally different cases should be discriminated. Transition metal oxides and carbides were found to be efficient local sources of atomic oxygen increasing its abundance much above the uncatalyzed case. Streams of diffusing oxygen atoms created decorated pathways of nonselective oxidation of basal plane sites as detected by transmission electron microscopy [117, 118].

In the rheological phase system there are many advantages the surface area of solid particles can be efficiently utilized, the contact between solid particles and fluid is close and uniform, heat change is very efficient, local overheating can be avoided, and the reaction temperature can be easily controlled. In addition, many substances have greatly increased solubility and new reaction behavior in this state.

Some properties also hold if n is not a generalized Blum integer. Thus one can sometimes omit a zero-knowledge proof (see the end of Section 8.1.3) and use a more efficient local verification algorithm. Hence most definitions are presented for more general integers n. 

There is no evidence for a metastable extension of the liquid phase into the coexistence region, in marked contrast to the situation in 3D, in which a metastable liquid branch is all too easily obtained. A possible explanation of this difference may lie in the fact that 3D systems are inherently frustrated, in the sense that the most efficient local packing of... 

Efficient use of symmetry can greatly speed up localized-orbital density-functional-exchange-and-correlation calculations. The local potential of density functional theory makes this process simpler than it is in Hartree-Fock-based methods. The greatest efficiency can be achieved by using non-Abelian point-group symmetry. Such groups have multidimensional irreducible representations. Only one member of each such representation need be used in the calculation. However efficient localized-orbital evaluation of the chosen matrix element requires the sum of the magnitude squared of the components of all the members on one of the symmetry inequivalent atoms, based on Eq. 13. 

Analysis of the solution stmcture of a protein can be carried out by using redox-active metal centers (25). For example, [Cu(phen)2] was exploited in the structural analysis of Escherichia coli lactose permease, a paradigm for membrane transport proteins (73). By the reaction of Y with a functional lactose permease mutant, phen was covalently linked to a single cysteine residue situated within one of the 12 membrane-spanning a-helices of the protein. After Cu(n) ion was bound to the phen moiety of the modified protein and ascorbate was added in the presence of O2, efficient, localized scission (up to 30%) of the protein backbone was observed in adjacent helices, providing information on the structure of the protein. 

The high buffering capacity of the Lanarkshire soil (experiment B) compared with experiment A, is demonstrated by the limitation of acidification and associated iron staining to within -lOcm of the anode. However, a pH jump did emerge after 3 weeks, with alkaline conditions prevailing in -60% of the experimental cell. The 96.8% reduction in the Cr(VI) content of the cathode zone, as well as the 84.4% decrease in the anodic zone, suggests that stabilization was advanced. The complementary 25.8% increase in Cr(T) around the anodic array, as well as the associated 17.4% reduction in Cr(T) around the cathode array (Fig. 8.3), is consistent with the anodic domain operating as an efficient localized zone of Cr(VI) reduction to Cr(III). 

In some cases, precipitates at the grain boundaries may be more noble than the bulk material these precipitates will stimulate grain boundary attacks by acting as efficient local cathodes (e.g. CuAb in aluminium alloys).

As mentioned, the convergence of the 2x2 scheme is slow and not so reliable, especially for delocalized covalently bonded systems. It was strongly desired to develop a more reliable and more efficient localization scheme, both reliable and efficient. Gu et al worked out a new localization scheme based on the density matrix approach on the regional localized molecular orbitals (RLMOs). This new localization scheme works very well even for delocalized systems, and tests on some model systems have been reported. 

The optimization of ah initio Born-Oppenheimer potential energy surfaces is an important subject in quantum chemistry. Methods for the efficient localization and characterization of stationary points of the molecular potential energy surface are an essential tool in studies of molecular structure and reactivity. Of particular importance are methods for the determination of minima and first-order saddle points, corresponding to molecular equilibrium structures and transition states.
