Expression of the results

Following the steps shown in section IV.B which remain valid within the exchange approximation, one may easily obtain the expression of the resulting spectral density /Sf ex ... 

Significant differences can easily be calculated, when precision data for repeatability and reproducibility are used. Quality controls based on the validation data can be used to confirm that the method is in control and producing meaningful results. Estimation of the measurement uncertainty enables expression of the result as a range of values in which the tme value for the measurement can be said to lie within a stated level of confidence. 

Methods involving quantitation of conjugated azopigment directly measure the number of groups transferred and thus, by calculation, GTR. Expression of the results in function of bilirubin equivalents conjugated is equivocal. 

The resiliency quoted for an elastomer is normally a single expression of the result of a specified test. The results quoted will vary according to the method used. To compare results, elastomers must be tested by the same method. 

M = molecular weight, grams per mole of the acid chosen for expression of the results. 

Both general and special positions are also called Wyckoff positions, in honor of the American crystallographer Ralph Walter Graystone Wyckoff (1897-1994). Wyckoff s 1922 book. The Analytical Expression of the Results of the Theory of Space Groups, contained tables with the general and special positional coordinates permitted by the symmetry elements. This book was the foremnner of International Tables for X-ray Crystallography, which first appeared in 1935. 

In the expression of the results, the total amount M in volume per cent, of the solution in chloroform is given. If the specific gravity of the liquid nitric peroxide at the temperature considered is Sy there are 10 SM kilograms... 

In general, an index corresponds to expression of the results obtained in different toxicity tests by means of a number that allows the toxicity of the sample to be classified.

The invention of the VI concept led to its becoming an immediate success after its publication, since it met the criteria of simplicity, ease of determination (measurement of viscosity at two temperatures), and expression of the result as a simple number between 0 and 100 for all oils with a viscosity at 100°C of greater than 2.0 cSt. Oils with viscosities at 100°C of less than 2.0 cSt ran into measurement problems at 210°F or 100°C because of the loss by distillation of lower boiling components at this temperature during the test. 

In reporting a single test, it is preferable merely to record results as observed, indicating the amounts tested and the result in each, rather than to attempt expression of the result in numbers of B. coli...
