Compact form

M/here is a positive quantity depending only on the (empirical) temperature of the surroundings. It is understood that for the surroundhigs = 0. For the integral to have any meaning must be constant, or one must change the siirroimdings in each step. The above equations can be written in the more compact form... [Pg.341]

In principle, Chen, given the flux relations there is no difficulty in constructing differencial equations to describe the behavior of a catalyst pellet in steady or unsteady states. In practice, however, this simple procedure is obstructed by the implicit nature of the flux relations, since an explicit solution of usefully compact form is obtainable only for binary mixtures- In steady states this impasse is avoided by using certain, relations between Che flux vectors which are associated with the stoichiometry of Che chemical reaction or reactions taking place in the pellet, and the major part of Chapter 11 is concerned with the derivation, application and limitations of these stoichiometric relations. Fortunately they permit practicable solution procedures to be constructed regardless of the number of substances in the reaction mixture, provided there are only one or two stoichiomeCrically independent chemical reactions. [Pg.5]

This is the most compact form for the complete flux relations. [Pg.35]

Light or heavy magnesium carbonate is exposed to a red heat, and carbon dioxide and water are expelled leaving light or heavy magnesium oxide. The density is also influenced by the calcining temperature higher temperatures yield more compact forms. [Pg.200]

Sanitizer and Chemical Feeders. Eeeders dispense the chemicals in gaseous, Hquid, and soHd (both granular and compacted) forms. Many health departments require that pubHc pools have approved feeding devices for the daily appHcation of all chemicals, including saniti2ers. A slurry feeder for diatomaceous earth (DE) on diatomite filter installations may also be required. [Pg.297]

All points on the boundary of a growing nucleus are coupled by the diffusion field, and the nucleus can differ from its inital compact form as is shown in Fig. 5. This will be explained further in Secs. IVE and V [7,15,17,101]. [Pg.885]

For a 3-cm-long molecule of DNA to fit inside a cell so tiny that we can only see it with a microscope, the polynucleotide chain must be folded into a more compact form. Not only must the DNA be compacted, it must be folded in a way that allows it to cany out its main functions. The way the chain is folded defines the tertiary structure of a nucleic acid. [Pg.1171]

In some circumstances, separation of solid from a liquid is better achieved by use of a centrifuge than by filtration, and a small, electrically driven centrifuge is a useful piece of equipment for an analytical laboratory. It may be employed for removing the mother liquor from recrystallised salts, for collecting difficultly filterable precipitates, and for the washing of certain precipitates by decantation. It is particularly useful when small quantities of solids are involved centrifuging, followed by decantation and re-centrifuging, avoids transference losses and yields the solid phase in a compact form. Another valuable application is for the separation of two immiscible phases. [Pg.103]

Volumes of H2 and O2 identifies this as a stoichiomehy problem, for which our seven-step approach, presented here in compact form, is appropriate. The problem asks about amounts of chemicals... [Pg.1410]

Ion binding reduces the repulsive forces between the charged groups on the polyanion but, unless the counterions are site-bound, the repulsive osmotic forces are not affected. At full neutralization the coulombic forces along the polymer chain become zero. However, the polymer does not contract, because the osmotic forces remain unless, of course, all the cations become site-bound. (Of course, in the case of a free weak acid the concentration of mobile hydrogen ions is very small and the polymer adopts a compact form.)... [Pg.84]

The hyperpolarizability tensor is obtained in a way similar to the case of SHG. However, the selection rules for an SFG resonance at the IR frequency implies that the vibrational mode is both IR and Raman active, as the SF hyperpolarizability tensor elements involve both an IR absorption and a Raman-anti-Stokes cross-section. Conversely, the DFG hyperpolarizability tensor elements involve an IR absorption and a Raman-Stokes cross-section. The hyperpolarizability tensor elements can be written in a rather compact form involving several vibrational excitations as [117] ... [Pg.157]

By remembering that the inverse of the function l/(s+Xi) is e, the general solutions can be written in a rather compact form as ... [Pg.23]

All equations given in this text appear in a very compact form, without any fundamental physical constants. We achieve this by employing the so-called system of atomic units, which is particularly adapted for working with atoms and molecules. In this system, physical quantities are expressed as multiples of fundamental constants and, if necessary, as combinations of such constants. The mass of an electron, me, the modulus of its charge, lei, Planck s constant h divided by lit, h, and 4jt 0, the permittivity of the vacuum, are all set to unity. Mass, charge, action etc. are then expressed as multiples of these constants, which can therefore be dropped from all equations. The definitions of atomic units used in this book and their relations to the corresponding SI units are summarized in Table 1-1. [Pg.21]

In the discussion of kinetic equations and transport properties it is convenient to write the evolution equation in more compact form as... [Pg.98]

The nature of the solvent influences both the structure of the polymer in solution and its dynamics. In good solvents the polymer adopts an expanded configuration and in poor solvents it takes on a compact form. If the polymer solution is suddenly changed from good to poor solvent conditions, polymer collapse from the expanded to compact forms will occur [78], A number of models have been suggested for the mechanism of the collapse [79-82], Hydrodynamic interactions are expected to play an important part in the dynamics of the collapse and we show how MPC simulations have been used to investigate this problem. Hybrid MD-MPC simulations of the collapse dynamics have been carried out for systems where bead-solvent interactions are either explicitly included [83] or accounted for implicitly in the multiparticle collision events [84, 85]. [Pg.124]

To deal with all the observations h e H in compact form, the unitary structure factor components can be arranged in a vector Urand, and the components of the constraint functions collected in a vector C(x). The MaxEnt distribution of electrons (x) then takes the form... [Pg.17]

The (compositionally) simplest mineral class comprises the native elements, that is, those elements, either metals or nonmetals that occur naturally in the native state, uncombined with others. Native gold, silver, and copper, for example, are metals that naturally occur in a ductile and malleable condition, while carbon - in the form of either graphite or diamond -and sulfur are examples of nonmetallic native elements. Next in compositional complexity are the binary minerals composed of two elements a metal or nonmetallic element combined with oxygen in the oxides, with a halogen - either fluorine, chlorine bromine, or iodine - in the halides, or sulfur, in the sulfides. The oxide minerals, for example, are solids that occur either in a somewhat hard, dense, and compact form in mineral ores and in rocks, or as relatively soft, unconsolidated sediments that melt at moderate to... [Pg.36]
