Significance meaning

The flux of material to and from the electrode surface is a complex function of all three modes of mass transport. In the limit in which diffusion is the only significant means for the mass transport of the reactants and products, the current in a voltammetric cell is given by... [Pg.512]

There should be specific, saturable binding to the receptor, accompanied by pharmacological characteristics appropriate to the functional effects, demonstrable using a radioactive, eg, tritium or iodine-125, ligand to label the receptor. Radioligand binding assays (1,6) have become a significant means by which to identify and characterize receptors and enzymes (see Immunoassays Radioactive tracers). Isolation of the receptor or expression of the receptor in another cell, eg, an oocyte can be used to confirm the existence of a discrete entity. [Pg.517]

Air Transport. Relatively small quantities of chemicals are transported by air, although availability of such service for the movement of samples, emergency shipments, and radioactive chemicals with a short half-life is important. Both economic and safety considerations impede the development of air carriage as a significant means of transporting a substantial volume of chemicals. [Pg.257]

Pollution prevention is always preferred to the use of end-of-pipe pollution control facilities. Therefore, every attempt should be made to incorporate cleaner production processes and facilities to limit, at source, the quantity of pollutants generated. The choice of flash smelting over older technologies is the most significant means of reducing pollution at source. Sulfur dioxide emissions can be controlled by ... [Pg.136]

In this relation,

mathematical function, which depends on the electrode potential AU= U- Up, and has, as we will see, a significant meaning for microwave electrochemistry ... [Pg.462]

Mean depression in CO2 uptake rates induced after 1-hr exposures, and 95% confidence interval. (Superscripts and denote those significant means at the P.Ol and P.05 levels, respectively, when compared with the summed depressions determined for the separately applied pollutants at corresponding concentrations. )... [Pg.123]

Earlier editions of this book had a complete chapter devoted to this subject which opened by commenting that it was tempting to claim that it was the most important chapter. The reasoning was that, whatever property we measure, whatever test method we use we end up with results and the question "What do the figures really mean " Results are useless unless we know their significance significance means statistics. However, at that time it was very unusual for statistical methods to be applied to rubber testing. [Pg.13]

An example may be cited of an individual who found significant meaning in a biblical passage during a session with morning-glory seeds ... [Pg.222]

In 15 consecutive patients, serum leptin concentrations were measured at baseline and after 8 weeks of lithium treatment. There was a significant mean increase of 3.5 ng/ml and serum leptin correlated positively with weight gain (5.9 kg), increased BMI (24-27), and clinical efficacy (699). The authors suggested that leptin might play a role in lithium-induced weight gain. [Pg.620]

In Tab. 5-13 we report the results of both mentioned strategies for the selection process. In both procedures the WILKS lambda varies monotonously and each set has a significant meaning. We may, therefore, stop the selection process following the misclassification rate. In the forward strategy the first zero error rate appears with the feature set Ti, Mg, Ca in step 3 (Fig. 5-25) whereas in the backward strategy the zero error rate is obtained with the remaining elements Si, Ca, Al, Mg in step 3. Now it is up to the expert to decide which feature set to retain in the future. [Pg.193]

Covalent bonds are much different then ionic bonds, as they share electrons rather then capture them. Remember that ionic bonds are formed when two or more elements with distinctive differences in electro negativities react with one another—whereby the greater electronegative element captures an electron (or more) from the less electronegative elements). Covalent bonds, however, are formed when two or more elements combine and the electrons are shared (paired) rather then captured. In order for a covalent bond to form, the electronegative differences between the elements cannot be very significant, meaning their differences are much less then those encountered with ionic bonds. [Pg.5]

Coals produced in various parts of the world may be arranged in terms of Ro and MF as shown in Figure 4, which is referred to as the MOF diagram. Thus, Ro and MF have significant meanings in the evaluation of a coal in terms of coke strength. [Pg.264]

All models, however, have the same deficiency, that is, the concentrations in the solid and solution can be measured experimentally however, the surface activity coefficients, the surface electric work, as well as the energy distribution function can only be estimated. It means that the models are adapted to the experimental data and the best-fitted model is used, and therefore the selected model has no thermodynamically significant meaning (Cemik et al. 1995). In this chapter, these problems will be illustrated and discussed. [Pg.51]
