Burnett results

The results themselves have a subtlety associated with their interpretation owing to the presence of the volume-ratio parameter and, optionally, the initial density parameter. The Burnett equations have more flexibility to fit Burnett data than only a density series to PVT data. The statistical uncertainties reflect the quality of the experimental data relative to the particular model used to describe the experiment. The estimation of accuracy for Burnett results is necessarily somewhat subjective since the effect of systematic errors on parameter values is not explicit in nonlinear equations, such as the Burnett equations. Accuracy, however, can be estimated from a study of the effects of systematic errors in computer model calculations and from the magnitude of the change in the volume-ratio value determined with nonideal and nearly ideal gases. For these reasons, we include such information along with our virial coefficient results for ethylene.

Hematological Effects. The cyanosis that has been reported in a number of cases of accidental exposure to hydrogen sulfide is believed to result from respiratory distress (Arnold et al. 1985 Burnett et al. 1977 Deng and Chang 1987 Peters 1981 Ravizza et al. 1982 Stine et al. 1976 Tvedt et al. 1991a, 1991b).

As detailed by Gatehouse and Tweats (1987), the nature and concentration of solvent may have a marked effect on the test result. Dimethysolphoxide is often used as the solvent of choice for hydrophibic compounds. However, there may be unforeseen effects, such as an increase in mutagenicity of some compounds, for example, / -phcnylenediamne (Burnett et al., 1982) or a decrease in mutagenicity of others, such as simple aliphatic nitrosamines (Yahagi et al., 1977). It is essential to... 

Many enzymes extracted from higher plants have been tried for clotting cheese milk (Burnett 1976), however, attempts to use them have been unsuccessful. Most plant proteases are strongly proteolytic and cause extensive digestion of the curd, which has resulted in reduced yields, bitter flavors, and pasty-bodied cheese. 

The very low value of Ashmore and Burnett is difficult to explain. It is easy to demonstrate that the discrepancy is not resolved by assuming the N03 intermediate in nitrogen dioxide decomposition is the pernitrite radical, in contradistinction to the symmetric nitrate radical. Their calculation of k5 depended on an experimentally obtained value for k 5 and an equilibrium constant K5- 5 calculated from thermodynamic properties for N03 measured by Schott and Davidson and Ray and Ogg. These results, obtained in a nitrogen pentoxide system, pertain to the nitrate radical, not the pernitrite radical. Guillory and Johnston176 reported an equilibrium constant based on estimated... 

Thus, to date the dependence of the rate of reaction on foreign gases or deviation from classic third-order behavior is not settled. The results of Johnston and Slentz231 and Ashmore, Burnett, and Tyler9 clearly indicate no anomalies over a wide range of [N0]/[02] ratios and inert gas pressures the experiments of Tipper and Williams421 and Sole suggest just the opposite. 

Although their results for uncatalyzed oxidation agree with those of other workers, the results in the presence of N02 do not. Furthermore, the proposed mechanism leads to a rate law with an additional factor of two in the far right-hand term. The combination of rate constants kBK2,-2 41,-41 is kinetically equivalent to k.1<, which leads to a value of 2k i6 = 1.28 x 104 AT-2 sec 1 from their data. This value is 100 times as large as the value found by Ray and Ogg357 and 64 times as large as the value deduced by Ashmore and Burnett.8... 

Burnett and coworkers have described the synthesis of a very potent class of cholesterol absorption inhibitors (CAI) typified by the original lead compound in this series the compound I showed in Fig. 42 (SCH 48461). This 2-azetidinone has resulted as an effective inhibitor of cholesterol absorption in a cholesterol-fed hamster model [9]. Subsequently, the same molecule has been shown to reduce serum cholesterol in human clinical trials [382]. Although this class of compounds has been initially designed as acyl coenzyme A cholesterol transferases (ACAT) inhibitors, early structure-activity studies demonstrated a striking divergence of in vitro ACAT inhibition and in vivo activity in the cholesterol-fed hamster. A detailed examination of this molecule indicated that the hypocholesterolemic...

On reviewing and reinvestigating the polymerization of MMA in the presence of halogenated benzenes and other aromatic solvents, Barn-ford and Brumby (3) have shown that the dependence of the rate of polymerization on the nature of the solvent arises partly from the viscosity dependence of the termination coefficient and partly from the dependence of the propagation rate constant on the nature of the solvent, and that the rate of initiation is not influenced by the nature of the solvent. Their results are compatible with the hypothesis of Henrici-Olive and Olive, but they contradict the suggested mechanism of Burnett et al. (I, 10) which considers solvent participation in the initiation step. 

The in situ precipitation technique and transmission electron microscopy have been used to investigate the effect of DMSO on percutaneous absorption in the mouse barrier [27] and human SC [46]. Sharata and Burnette examined ultrastructural changes in mouse stratum comeum by determining the distribution of sulfide precipitates of topically applied, water-soluble tracers (Hg and Ni ) after application of enhancer [27]. For skin pretreated with DMSO, mercury and nickel precipitates were found within swollen basal stratum comeum cells as well as intercellularly and associated with the cell envelopes, but not below the stratum comeum-stratum granulosum interface. It was concluded that treatment with DMSO, as well as with other dipolar aprotic solvents such as DMF and DMA, alters the passive intercellular diffusion pathway by expanding the size of the basal stratum comeum cells, resulting in an increased free volume for tracer diffusion.

The Enskog [24] expansion method for the solution of the Boltzmann equation provides a series approximation to the distribution function. In the zero order approximation the distribution function is locally Maxwellian giving rise to the Euler equations of change. The first order perturbation results in the Navier-Stokes equations, while the second order expansion gives the so-called Burnett equations. The higher order approximations provide corrections for the larger gradients in the physical properties like p, T and v. 

Results to date indicate that a number of low molecular weight inhibitors and small peptides are effective against BoNT in cell-fiee in vitro systems (Sukonpan et al., 2004 Boldt et al., 2006a, 2006b Park et al., 2006 Burnett et al., 2007 Eubanks et al., 2007).
