3 Theoretical and Experimental Results Various results of interest are worth noting  [Pg.10]

In the same way, the profiles of temperature developed through the thickness of the slab are calculated. [Pg.10]

In terms of boundary conditions, it should be noted that the temperature of the rubber is assumed to be instantaneously equal to the temperature of the mold surface with which it is in contact. If it is true, after a while when equilibrium is reached, for short times the equality of heat flux on both surfaces at the rubber-mold interface should stand as follows  [Pg.10]

This equality in the flux at the beginning of the process leads to lower cure at short times. And more, it depends on the characteristics of the mold, i.e., thickness and heat diffusivity. [Pg.10]

If the values of the cure enthalpy are pretty well given for several varieties of rubber compounds, the values of the energy of activation are not shown. An interesting apparatus was built and successfully tested for measuring the thermal conductivity of various rubbers with or without fillers. [Pg.10]


During the control, the reception coil has been scanning inside of the emission coils. The theoretical and experimental results have been obtained under the condition of a constant lift-off of 50 pm, obtained by applying a protective polyethilenic foil. [Pg.377]

In developing theoretical problems he always thought about practical uses of results in the national economy. His theoretical and experimental results were applied to developing numerous methods of analytical determination of elements in complex natural and technical situations, and also he also used the principles for improving the university curriculum and to generate new special courses. [Pg.6]

Figure 6 Theoretical and experimental results for an ordered and a disordered system on the left theoretical data for a CusPt single crystal and on the right experimental findings for a CusPt alloy overlayer on a platinum substrate. The spectra for the ordered species are traced with continuous lines, whereas those for the disordered species are given in dotted lines. The spectra were normalized to equal peak height.

We begin the comparison of experimental data with predictions of the conventional theory for results related to flow of incompressible fluids in smooth micro-channels. For liquid flow in the channels with the hydraulic diameter ranging from 10 m to 10 m the Knudsen number is much smaller than unity. Under these conditions, one might expect a fairly good agreement between the theoretical and experimental results. On the other hand, the existence of discrepancy between those results can be treated as a display of specific features of flow, which were not accounted for by the conventional theory. Bearing in mind these circumstances, we consider such experiments, which were performed under conditions close to those used for the theoretical description of flows in circular, rectangular, and trapezoidal micro-channels. [Pg.107]

Geometries, hyperfme structure, and relative stabilities of the different positional isomers of monodeuterated benzene cations have been studied theoretically by density functional theory, using the B3-LYP functional, and experimentally by ESR and ENDOR spectroscopy. A comparison between theoretical and experimental results at 30 K gives acceptable agreement, but further experiments on multiply deuterated species should improve the analysis by making the effects of deuteration larger. [Pg.339]

More recently (2006) we performed and reported quantitative structure-activity relationship (QSAR) modeling of the same compounds based on their atomic linear indices, for finding fimctions that discriminate between the tyrosinase inhibitor compounds and inactive ones [50]. Discriminant models have been applied and globally good classifications of 93.51 and 92.46% were observed for nonstochastic and stochastic hnear indices best models, respectively, in the training set. The external prediction sets had accuracies of 91.67 and 89.44% [50]. In addition to this, these fitted models have also been employed in the screening of new cycloartane compounds isolated from herbal plants. Good behavior was observed between the theoretical and experimental results. These results provide a tool that can be used in the identification of new tyrosinase inhibitor compounds [50]. [Pg.85]

The adsorption mechanism in chromatography on alumina differs from that on silica gel because of the structural differences between these adsorbents. Relationships between the values of solutes and the adsorption data for the mobile phase components on sihca gel G and alumina G have been investigated by Rozylo [64,65]. The theoretical and experimental results obtained by the relation 2 = /( 1) show a good agreement for the two adsorbents. [Pg.88]

Not pursuing the objective to describe the adsorption phenomenon in detail, we would like, however, to dwell briefly on its principle ideas as well as on main theoretical and experimental results necessary for further understanding of the concept of the method of semiconductor sensors. [Pg.13]

Based on the collation of the theoretical and experimental results, two distinct NO activation pathways can then be proposed. The oxidative adsorption, giving rise to the bound NO8 species, defines a nitroside pathway of activation, while the reductive adsorption leading to NOs+ species is tantamount with a nitrosonium pathway of activation (Figure 2.17). [Pg.51]

From a very general outlook, one can argue that the NMR studies of quadrupolar nuclei present in nanoscale semiconductors should offer a more incisive look into the chemical and electronic structure than do studies of spin-1/2 nuclei. The rationale is that quadrupolar nuclei can report on the same chemical, hyperftne, or Knight shifts and dipolar or indirect couplings as observed for spin-1/2 nuclei, but also provide an additional dimension of information in terms of the NQCC and associated EFGs. Although not yet reported, DFT calculations of both chemical shifts and NQCC values for the same nuclei in nano-semiconductors should provide a more stringent comparison of theoretical and experimental results, particularly if the two parameters can be correlated experimentally, as seems feasible. [Pg.297]

In summary, from the above theoretical and experimental results, it is concluded that ionic diffusion towards self-affine fractal electrode should be described in terms of the apparent selfsimilar fractal dimension rather than the self-affine fractal dimension. In addition, the triangulation method is one of the most effective methods to characterize the self-similar scaling property of the self-affine fractal electrode. [Pg.389]

Our implementation computes only vertical ionization energies and electron affinities, but experimental results for the G2 species are adiabatic. To facilitate a direct comparison between the theoretical and experimental results, it is necessary that either the theoretical results be corrected to adiabatic values or that the adiabatic values be related to vertical ones. We have chosen the latter approach and have corrected the experimental results with computational data. [Pg.151]

Because most shear-thinning fluids, particularly polymer solutions and flocculated suspensions, have high apparent viscosities, even relatively coarse particles may have velocities in the creeping-flow of Stokes law regime. Chhabra(35,36) has proposed that both theoretical and experimental results for the drag force F on an isolated spherical particle of diameter d moving at a velocity u may be expressed as a modified form of Stokes law ... [Pg.169]

They complement theoretical and experimental results already presented in the older literature [87, 88,108]. [Pg.629]

Influenced by interfacial tension and centrifugal forces, spherical drops of various diameters originate at the holes. If we again assume the Sauter diameter, according to Eq. (9.1), as the mean diameter of the spectrum of particles, the following equation for heavy and light phases results from theoretical and experimental results [10] ... [Pg.387]

A comparison of the theoretical and experimental results for the IPN system cross-poly(n-butyl acrylate) inter-cross polystrene is given in Table II [18,21]. The agreement between theory and experiment for this system as well as other systems was better than expected, noting the approximations required to obtain a usable result. It must be pointed out that Yeo et al. had to use spherical shapes for their mathematical treatment, even though it was already recognized that most of the domains were cylindrical. [Pg.275]
