Expressed needs

B. Defining the Reaction Kinetics and Component Physical Properties. The rate expression needed for use in a vent design model should represent the condition that would exist during the emergency. Kinetic data based on the normal reaction rate are only useful in cases when loss of heat transfer can be experienced. [Pg.332]

Design and implement data collection strategies aimed at tapping one or more levels of program effects. These strategies should reflect the audience s expressed needs for information. [Pg.308]

Hypersonic aircrafts and reentry vehicles such as Sanger, Hermes, Express, need reusable hot structures. Typical examples are nose cones, wing leading edges, winglets, flaps, rudders, shingles etc. [Pg.310]

The atomic and molecular wave functions are usually described by a linear combination of either Gaussian-type orbitals (GTO) or Slater-type orbitals (STO). These expressions need to be multiplied by a center dependent factor expf ip-A). Further the STOs in momentum space need to be multiplied by Yim(6p,p). Examining the expressions [4], one notices the Gaussian nature of the GTOs even after the FT. The STOs are significantly altered on FT. From the expressions in Table 5.1, STOs are seen to exhibit a decay which is the decay of the slowest Is... [Pg.56]

The final expression needed to complete the SR model is a closure for eaD appearing in (A.20). In order to develop a model starting from (A.2), we will first introduce the scalar... [Pg.387]

When we wanted to numerically fit experimental PFGE data of water diffusion in a water-in-oil emulsion, we found that for a beginner in this field the literature is quite confusing. First, all three expressions for diffusion in a sphere with reflecting walls are somewhat different and lead to very different fitting results, especially when the formulas are combined with a radius distribution function. Since the derivation of the published expressions needs some tedious algebra (which has not been published), it is not trivial to check the derivation in order to establish which expression is the correct one. Here we use a numerical approach to decide which expression is correct. [Pg.202]

Experimentally the key to the method is determining the relative population of triplet molecules by the optical density of triplet-triplet absorption following flash excitation. To derive the kinetic expressions needed to determine O , the scheme is the same as that written previously with the additional proviso that the singlet interaction lead to intersystem crossing by the sensitizer. [Pg.276]

The terms in delta functions will be integrated to get the invariant 5 , which is still space- and time-independent. Hence, these two Green s functions can be combined as they can have the same value at the moment of particle creation (t = 0) and at this time only these terms are non-zero. This expression needs a little further manipulation. Following Lebedev et al. [506] on the variational principle, drop the term V ZJe- 17 VGG and include a new term of the form V (Ae fJUG G — e u4>G — e u4tG )r where f is a unit radial vector and

scalar functions of r which are related directly to the boundary conditions which both G and G satisfy. Multiply the delta function term by 2. [Pg.303]

In the foregoing, the expressions needed to account for mass transport of O and R, e.g. eqns. (23), (27), (46), and (61c), were introduced as special solutions of the integral equations (22), giving the general relationship between the surface concentrations cG (0, t), cR (0, t) and the faradaic current in the case where mass transport occurs via semi-infinite linear diffusion. It is worth emphasizing that eqns. (22) hold irrespective of the relaxation method applied. Of course, other types of mass transport (e.g. bounded diffusion, semi-infinite spherical diffusion, and convection) may be involved, leading to expressions different from eqns. (22). [Pg.263]

The relation (A 7.5) first was derived by de Gennes, initiating the renormalization group or scaling approach to polymer solutions. Again these expressions need some explanation. Equation (A 7.6) defines G/ (r, r 7 q) as path integral , summing over all continuous paths r(s), 0 < s < Rh r(0) = r r(Rg) = r. It is properly defined as the continuous chain limit of the discrete... [Pg.119]

The job of a marketer (and the job of a health care professional as well) is not only to understand and respond to people s expressed needs but also to help customers learn more about what they need and want. In essence, marketers also must understand and respond to people s latentne ls. Narver, Slater, and MacLachlan (2004) call the former a responsive market orientation and the later a proactive market orientation. Marketers do not create needs, but they do help consumers to understand their latent needs and to translate needs into wants. An understanding of this issue is helpful in explaining pharmacy s current experiences with patient-centered services. [Pg.342]

BS and finally B is desorbed to free the active site that can now catalyse another cycle. We assume that the surface reaction is the slowest and therefore the limiting step. The kinetic expression we derive is valid only under this assumption and if the assumption changes, another expression needs to be derived. Since the surface reaction is the slowest step, we assume that all other reaction steps are so fast that they are at equilibrium. [Pg.36]

The detailed description of H, for which there is no analytical expression, needs the knowledge of other parameters the structure and dimensionality of the lattice, and the nature of the interactions Knm. Fora qualitative description, we restrict ourselves to the above three parameters and consider first the low-temperature case in limit situations ... [Pg.45]

As shown. Equation (43) still expresses [5ppo4Feiii] in terms of two variables, [Fe ] and [H ]. We want it expressed only in terms of the K constants and the hydrogen ion concentration. This is where an expression needs to be found to eliminate [Fe ]. If this expression indicates that some compound of iron is coprecipitating with FeP04, then [Fe ] could be eliminated using the K constant of this compound. [Pg.70]

The last expression needed is the Poisson equation. In a field of homogeneous dielectric constant e,... [Pg.545]

For the full value of the receptor gene sequence to be realized, the function of the expressed orphan receptor, as well as its regulation and expression need to be... [Pg.3122]

In addition, there is also an expressed need for fuel-flexible injector nozzles. In the past, some nozzles have experienced vibration problems because of the load and feedstock changes. Nozzles are desired that can operate with more than one feedstock, with no adverse effect on the operation, and no need to shut down to switch nozzles whenever the conditions require a change in feedstocks. [Pg.208]

Table 1 lists the experimental values of quantities and expressions needed in calculating the rate constants of certain photoprocesses. [Pg.63]
