Nakamura model

Patel and coworkers [175] also suggested a differential form for the Nakamura model ... 

The principal drawback of the Nakamura model is that it does not consider the effect of the induction time. Chan and Isayev [176] proposed to calculate non-isothermal induction times, ti from isothermal ones according to the equation ... 

Hieber has shown that a number of studies of nonisothermal crystallization of isotactic poly(propylene) and poly(ethylene terephthalate) can be treated by the Nakamura model.(88a) This model has also been shown to hold for syndiotactic poly(styrene) and poly(caprolactone). (98,98a) The results for linear polyethylene have not been conclusive. All of the studies have involved unfractionated polymers. In one study curvature was observed in the Ozawa type plot.(89) In another study, with a different sample, the Nakamura model was shown to hold.(88)... 

Zhu and Nakamura treated the two-state time-independent linear potential model (two linear diabatic potentials coupled by a constant diabatic coupling)... 

Third, a further simplification of the Boltzmann equation is the use of the two-term spherical harmonic expansion [231 ] for the EEDF (also known as the Lorentz approximation), both in the calculations and in the analysis in the literature of experimental data. This two-term approximation has also been used by Kurachi and Nakamura [212] to determine the cross section for vibrational excitation of SiHj (see Table II). Due to the magnitude of the vibrational cross section at certain electron energies relative to the elastic cross sections and the steep dependence of the vibrational cross section, the use of this two-term approximation is of variable accuracy [240]. A Monte Carlo calculation is in principle more accurate, because in such a model the spatial and temporal behavior of the EEDF can be included. However, a Monte Carlo calculation has its own problems, such as the large computational effort needed to reduce statistical fluctuations.

In model studies,224,225 oligosaccharides have been separated as their trifluoroacetates, and Vilkas and coworkers224 found that a tetra-saccharide so esterified had a retention time of six minutes at 250°. Similar results were obtained by Nakamura and Tamura,49 who showed that, on a column of OV-1 at 220°, the retention time of per-0-(trimethylsilyl)sucrose was 12 min, whereas, at 140°, the per(tri-fluoroacetate) required only 7 min. Other comparative data were provided for the common disaccharide alditols. A study of the concentration of lactose in blood was made by using this method 48 it was also shown48 that trifluoroacetylation of disaccharides proceeds more rapidly and satisfactorily in N,N-dimethylformamide than in ethyl acetate. 

Expansion or enhancement of the proposed mechanism of Nakamura and Okai is shown in Figure 12. Their model is based on the demonstration that several synthetically prepared di- and tri- peptide fragments composed of basic or acidic amino acids, produced individual tastes such as salty (lys-gfy sweet (lys-gfy-asp), sour (asp-glu-glu) and bitter (ser-leu-ala 31). Tlie expanded mechanism we propose is shown in Figure 12 and is based on the data tabulated in Table 1 (31, 38). 

Subject to modification concerning substitution possibilities noted below, the model we have in mind is of the "putty-clay" variety. That is, although there is a choice of coefficients before a process is Installed, the coefficients are fixed thereafter. This type of model has recently been examined by Myers and Nakamura (15). Their model permits a much wider scope for choice of coefficients than the limited set actually available for producing most chemical products.

Fujitani and Nakamura proposed the Cu-Zn active-site model.23-26 According to this model, the role of the Cu-Zn site is to activate the hydrogenation of the formate species. It is known that formate can form directly from C02 and H2.27 Originally the active site was suggested to be the Cu-O-Zn site but it was changed because of the results of surface science studies. ... 

Mizushima, Shimanouchi, Nakamura, Hayashi, and Tsuchiya (7.39)], have furnished a significant basis for our understanding of the types of isomeric chain configurations which can exist in chlorine-containing high polymers. Studies of this type are dictated by the particular polymer under investigation. Sometimes the necessary information will be found in the literature in other cases a careful study of such model compounds may have to be initiated in order to clarify certain aspects of the polymer spectrum.
