Resolvent formalism

This is all true when the stoichiometric disulfides are considered. What happens to chemical bonding upon sulfiir loss remains unknown. A possible solution of the problem appeared when the structures of SmSi.90 (Podberezskaya et al. 1999, Tamazyan et al. 2000b), DySi.84 (Podberezskaya et al. 1998), and DyS 7 (Tamazyan et al. 1994) were resolved. Formally, the chemical bonding may be characterized by the ionic formulas and by the interatomic distances in the structural series of the RS2 RS1.90 RSi.g4 RS].76 compounds. These distances are compared with the known radii (metallic, ionic, covalent) taken firom the Table of ionic radii in the ICSD databank (CRISTIN 1986). Considering the structures as alternating square nets, -(S2)-R-S-S-R-(S2-, two types of distances, within each layer (-(S2)-(S2)- R-R S-S ) and between the layers (R-S S-(S2) S-S), have been analyzed. In the sheet (R-S-S-R) or (RS)+ all the R-R and S-S distances are close to the sum of the appropriate metallic radii for R and ionic radii for and the R-S distances are close to the smn of the ionic radii of these elements. This means that the chemical bonding in this sheet is preferably ionic. [Pg.600]

In all of these cases, the extent and nature of supervision can vary greatly. Like management systems themselves, supervision can be results-oiiented or procedurally focused, depending on the preferences of the company and the individual. One boss may tell her staff, "Fix that problem we re having with the product specs in the ag-chem division," and expect to hear no more about it until the problem is resolved. Another supervisor with the same problem may expect a detailed situation analysis, formal recommendations, and con-... [Pg.67]

The individual responsible for completing the data input forms needs formalized training in data collection procedures, with written instructions on form completion, on data handling, and on documentation procedures. Other material needed to encode raw data properly must be available. In addition, these individuals need access to a consultant within the organization to help resolve questions that may arise. [Pg.216]

Notice that Rahman and Stiliinger make use of the concept of an effective pair potential. The potential energy of any substance may always be resolved systematically into pair, triplet, quadruplet,. .. contributions. If we consider N particles each with position vector R, then formally we can write... [Pg.68]

Furthermore, it can be seen from the study conducted by Ragins and Cotton (2000) that, under certain circumstances, the type of relationship (formal or ir formal) is irrelevant. In fact, Ragins now resolves the formal-informal dilemma by emphasizing that it is the quality of the relationship that matters, not whether it is formal or informal. And there is certainly the potential for high-quality relationships in both t)q5es of environment ... [Pg.132]

Most QI programs build upon an established quality assurance (QA) process. Quality assurance can be defined as a formal and systematic process in which problems in delivering health care are identified, solutions to the problems are developed and implemented, and follow-up monitoring then is carried out [30]. QA begins with problem identification. After possible sources of the problem are determined, solutions are developed and implemented. Then, the results of the intervention or solution are evaluated to determine whether or not the problem has been resolved. By incorporating a goal of continual improvement, a QA process can contribute to quality improvement activities. [Pg.803]

Winter, Underhill, and co-workers have published extensively on the cubic NLO properties of complexes of DT and related ligands,411 22 particularly those containing formally Ni11 centers. For example, time-resolved 1,064 nm DFWM was used to obtain resonantly enhanced values for group 10 complexes such as (157).411 15 The smaller of (157) compared with (156) is largely due to resonance effects since the absorption maximum of (157) is somewhat removed from the laser fundamental. However, figures of merit derived from measurements of 2 and linear and two-photon absorption (TPA) coefficients show that low optical losses render complexes such as (157) superior to (156)413 for potential all-optical switching applications.411 14... [Pg.656]

In the low energy region the measurements of Alien et al. went down only to 4 kK. but hexachlorobutadiene mull data indicated the presence of a further band at 3.0—3.4 kK.. This and the 5.6 kK. band were therefore readily identified as transitions within the spin-orbit split ground state manifold — the 3 kK. absorption as 3Tig (A) - 3i g (A) and the 5.6 kK. peak as 3Tlg (A) -+3T g (A, A). Allen et al. were unable to resolve the broad band at 30 kK. but it may be noted that six formally... [Pg.130]

However, these formal expressions are of no great help until we know how to operate with the exponential operator, which is very complicated because it involves the full iV-body problem with the interactions between the particles. In order to circumvent this difficulty, we shall use a resolvant technique 89 we define a resolvant operator (L — 2)-1, function of the complex variable z, and write ... [Pg.167]

Before finishing our formal manipulations, we still have to express the distribution functions (30) and (31) in terms of the resolvant operator it is not difficult to show that (see Eq. (32))... [Pg.168]

The person who has laid the most firm foundation for understanding this sort of notion philosophically is Alfred North Whitehead. Nothing we have suggested is beyond the power of his method to anticipate. Whitehead s formalism accounts for minds and organisms and a number of phenomena poorly resolved by the Cartesian approach. [Pg.151]
