Powers implied

The numerical factors in equations (70) to (73) are again statistical. The factors involving l raised to a power imply kinetic secondary isotope effects. The replacement of one protium atom by one deuterium atom increases the rate constant by i . This inverse isotope effect is qualitatively intelligible since the non-transferred nuclei are more tightly bound in the transition state than they were in the reactants. The existence of the secondary isotope effect also means that the ratio of rate constants in H20 and D20 ( H/fcD) Is not a measure of the primary isotope effect, whereas h o/3 h,do is- To obtain the primary isotope effect it is necessary to divide H/feD by Z2 - (For experimental evaluations of primary and secondary isotope effects see Kreevoy et al.t 1964 ... [Pg.279]

Thickness B-p becomes smaller as the diffusivity decreases because k varies with only the 0.56 power of the diffusivity instead of the 1.0 power implied by the film theory. If Eq. (21.51) were used, the corresponding values of Bp would be 0.066 and 0.053 in. These are somewhat closer to each other because is used instead of... [Pg.668]

The number of reported incidents and accidents has been higher for electrosurgery apparatus than other electromedical instrumentations. One reason for this is that it is made for therapeutic interventions with use of high RF power, implying that wire lengths of 2—3 m do exhibit strong antenna effect. [Pg.455]

The multi-bond graph notation, introduced by Breedveld [3,4], has major advantages. First, it enables the bond graph to be viewed in a more compact and concise manner. Second, it enables matrix elements to be inserted, and all the mathematical power implied by such. [Pg.324]

The basic character of the STAR-H2 passive load follow design strategy is as follows the Pb coolant outlet temperature should remain constant vs. fraction of full load whereas coolant temperature rise across the core should increase vs. fraction of full power - implying that core inlet temperature Tiniet decreases with increasing fraction of full load. This, in turn, increases the buoyancy driving head for natural circulation, which depends on differences in temperature of coolant exiting the core and the heat exchanger. [Pg.676]

To this reasoning, it has been objected, that the President by the influence of the power of nomination may secure the compliance of the Senate to his views. The supposition of universal venality in human nature is little less an error in political reasoning than the supposition of universal rectitude. The institution of delegated power implies that there is a portion of virtue and honor among mankind, which may be a reasonable foundation of confidence. And experience justifies the theory It has been... [Pg.371]

To obviate the objections made to the judicial power it has been said, that the Congress, in forming the regulations and exceptions which they are authorised to make respecting the appellate jurisdiction, will make provision against all the evils which are apprehended from this article. On this I would remark, that this way of answering the objection made to the power, implies an admission that the power is in itself improper without restraint, and if so, why not restrict it in the first instance. [Pg.523]

One objection to the discussion thus far is that the various doctrines of protective power imply a multivariate model of lead solvency, while the visual depictions above indicate a bivariate relationship. To address this objection, a series of regressions are run using the Maine data. The methods and results are reported in appendix C. The results indicate... [Pg.134]

The contribution that Hocking wished to make was to refine the sensor system and the instrumentation paekage so as to be able to incorporate the necessary functionality within a lightweight portable battery operated instrument. This implied a lower power level and very low-noise instrumentation. We aimed also for a low cost instrument able to operate for several hours from fully charged batteries and able to operate at a pull speed of 500mm/second. [Pg.321]

An important reason for low coordination of iodide ions is that high coordination implies a high oxidation state of the central atom, which often (but not always) means high oxidising power— and this means oxidation of the easily oxidised iodide ligands. Thus the nonexistence of, for example, phosphorus(V) pentaiodide is to be explained by the oxidation of the iodide ligands and reduction of phosphorus to the -(-3 state, giving only PI3, not PI5. [Pg.316]

It can be said that these three main strategies have been applied equally and very often in combination. Basically, the first approach implies the use of a faster computer or a parallel architecture. To some extent it sounds like a brute force approach but the exponential increase of the computer power observed since 1970 has made the hardware solution one of the most popular approaches. The Chemical Abstracts Service (CAS) [10] was among first to use the hardware solution by distributing the CAS database onto several machines. [Pg.297]

There are a few basic numerical and experimental tools with which you must be familiar. Fundamental measurements in analytical chemistry, such as mass and volume, use base SI units, such as the kilogram (kg) and the liter (L). Other units, such as power, are defined in terms of these base units. When reporting measurements, we must be careful to include only those digits that are significant and to maintain the uncertainty implied by these significant figures when transforming measurements into results. [Pg.33]

Experiments and even production operations can be conducted at any frequency providing the radiated and conducted signals meet the apphcable tfi limits for ISM equipment. Tests to certify this stipulation must be carried out before inception of operations. This implies weU-shielded enclosures at high power levels which is expensive but justified in certain apphcations. [Pg.338]

The term operational method implies a procedure of solving differential and difference equations by which the boundary or initial conditions are automatically satisfied in the course of the solution. The technique offers a veiy powerful tool in the applications of mathematics, but it is hmited to linear problems. [Pg.462]
