Values reliable

A significant dependence of the Si--Cl bond length on the nature of the other ligands in the molecule has been found, Microwave spectroscopy has provided the values (reliable to 0.002 A) 2.021 A in HSiCli, 2.021 A in CHsSiCls, and 2.048 A in Hs8iCl, corresponding, by the method oi interpretation given above, to about 18 percent, 18 percent, and 9 percent, respectively, of double-bond character. 

Methods to compute jF (t) values reliably have been discussed extensively by the above-mentioned authors, especially by Oldham who stated that eqn. (99) can be considered as the semi-integral of jF t), generated by the operator d-1/2/df-1/2. Consequently, various rules derived for semiintegration and semi-differentiation can be applied, placing the principle in a more general context [80]. 

The kinetic copolymerization models, which are more complex than the terminal one, involve as a rule no less than four kinetic parameters. So one has no hope to estimate their values reliably enough from a single experimental plot of the copolymer composition vs monomer feed composition. However, when in certain systems some of the elementary propagation reactions are forbidden due to the specificity of the corresponding monomers and radicals, the less number of the kinetic parameters is required. For example, when the copolymerization of two monomers, one of which cannot homopolymerize, is known to follow the penultimate model, the copolymer composition is found to be dependent only on two such parameters. It was proposed [26, 271] to use this feature to estimate the reactivity ratios in analogous systems by means of the procedures similar to ones outlined in this section. 

For our worldwide customers such technical progress creates multifaceted value reliability, shorter response time, more competitive economics, improved quality leading to faster registration, and safer and more environmentally responsible operations. Furthermore, it enables us to extend the use of this expertise to the adaptation of decisive physical or chemical properties of molecules to provide our customers with desired use properties. 

The BV of a food varies greatly and depends on a wide variety of factors. In particular the BV value of a food varies depending on its preparation and the recent diet of the organism. This makes reliable determination of BV difficult and of limited use—fasting prior to testing is universally required in order to make the values reliable.

With a median selector, the selector output is the median of three or more input signals. These devices are useful for situations in which redundant sensors are used to measure a single process variable. By selecting the median value, reliability is improved, because a single sensor failure will not cause the loss of a meaningful feedback signal. 

The determination of the functionality is an essential parameter in block polycondensation. Unfortunately, many of the values given in the literature are doubtful because they are obtained by only one analytical technique or they are implicitly assumed. Only the comparison of the molar masses obtained by direct determination (chromatography, tonometry, mass spectrometry, osmometry) and those calculated from the concentration of the end-groups is relevant. The latter is determined by e.g., chemical titration, NMR, or infrared spectroscopy the use of several methods increases the accuracy of the values. Reliable values are obtained when both direct and indirect determinations are taken into account. 

Such step-limiting is often helpful because the direction of correction provided by the Newton-Raphson procedure, that is, the relative magnitudes of the elements of the vector J G, is very frequently more reliable than the magnitude of the correction (Naphtali, 1964). In application, t is initially set to 1, and remains at this value as long as the Newton-Raphson correotions serve to decrease the norm (magnitude) of G, that is, for... 

C. These values are su but are not reliable for high accuracy in molar volumes. 

The volumetries of a field, along with the anticipated recovery factors, control the reserves in the field those hydrocarbons which will be produced in the future. The value of an oil or gas company lies predominantly in its hydrocarbon reserves which are used by shareholders and investors as one indication of the strength of the company, both at present and in the future. A reliable estimate of the reserves of a company is therefore important to the current value as well as the longer term prospects of an oil or gas company. 

The following values for the surface tension of a 10 Af solution of sodium oleate at 25°C are reported by various authors (a) by the capillary rise method, y - 43 mN/m (b) by the drop weight method, 7 = 50 mN/m and (c) by the sessile drop method, 7 = 40 mN/m. Explain how these discrepancies might arise. Which value should be the most reliable and why ... 

This fomuila does not include the charge-dipole interaction between reactants A and B. The correlation between measured rate constants in different solvents and their dielectric parameters in general is of a similar quality as illustrated for neutral reactants. This is not, however, due to the approximate nature of the Bom model itself which, in spite of its simplicity, leads to remarkably accurate values of ion solvation energies, if the ionic radii can be reliably estimated [15],...
