Precision: degree

On comparison with known Koppel-Pahn equation the equation (1) includes square of Hildebrandt s solubility parameter 2 [5], P.219-225. This equation (1) allows with acceptable precision degree to generalize all data from the work [1] (see Table) without necessity of exclusion the data for ethylacetate ... 

Previously published civilian studies of drug effects on performance over time did not give this problem much consideration, and usually included only 1-3 practice trials. In some cases, improvement by the time of recovery was indeed evident, but for the investigators it was usually not a matter of great concern since the objectives of their studies were usually limited to showing a statistically significant rather than a precise degree of impairment. 

In this way, pyridin-2-one and pyridin-4-one are calculated to be ca. - 30 kJ mor1 less aromatic than pyridine. In the bicyclic quinolone, the difference in aromaticity between the two forms is less. The precise degree of aromatic character possessed by 2- and 4-pyranone is not settled various methods of estimation give divergent values. 

In summary it may be concluded that while the Grunwald-Winstein analysis m values may be useful in delineating the broad mechanistic features of octahedral complexes, attempts to probe the precise degree of associative and dissociative character in the reaction are not feasible. 

Precision degree of reproducibility among several independent measurements of the same true value. 

Much work remains to be done in correlating the extent and the nature of conformational changes produced in proteins dissolved in chemically inert nonaqueous solvents and the precise degree to which these changes are reversible. In this connection the distinction must be made, of course, between the reversibility of conformational changes within covalently bound subunits of protein molecules, and the reversibility of the structural... 

Preparation of Hydrogel Arylsulfonyl Carbamates. To a solution of hydrogel (1-4.0 g) in dry pyridine (20-40 mL) was added eitherp-toluenesulfonyl Isocyanate (pTSI), 3.0 g, or p-nitro-benzenesulfonyl Isocyanate (p-NBSI), 0.5-3.0 g and the mixture was heated at 70 under nitrogen for 4 hr. The adduct was isolated by precipitation in benzene or ethanol. Repreclpltatlon from acetone or DMF yielded the desired products, IR (film) 3170 cm (-NH), 1530 cm" (-NO2), 1340, 1180 cm" (-SOj). The precise degree of substitution was determined by non-aqueous titration (Table II). 

At any given moment, the Moon is in one sign of the zodiac and one house of your chart. If you want to get persnickety about it, you could figure out exactly when the Moon will hit the precise degree of each house cusp. But who has time for that Not me. I suggest that you simply note the sign on the cusp of each house. When the Moon enters that sign, that s your cue to turn your attention to the matters of that house. For example ... 

What appears to be yet another variant, a statistical approach often called Monte Carlo simulation, recently has been demonstrated to apply by Walentowicz and Falco if the distribution of values for each input variable is known or can be approximated ( 1 ) Thereafter, this information can be manipulated to yield a distribution of outputs expressing probability of occurrence for any given value. Also, a recent study by Whitmore (20 develops the concepts of Walentowicz and Falco and offers conclusions on the form of final limiting distributions (e.g., simulated outputs for product functions approach log normal) if specific mathematical conditions are met. The precise degree to which the conditions must be fulfilled for the technique to yield a useful result in the present application have not yet been fully explored. 

Evidence for orthogonally twisted triplet states of enones has come from laser flash studies, though the precise degree of twist in particular cases is dependent on the flexibility of the molecule (Gioia et al.). The rates of unimolecular decomposition of tetramethyldioxetane from various vibrational levels to ground- and excited-state acetone molecules have been measured by an elegant procedure (Cannon and Crim). 

The four definitions above are the methods to test the model. They all judge the precision by criticizing the residues. To give values to a, e, Q P is to determine the degree of simulating the precision. The commonly used precision degrees can be seen in Table 1. 

Precision Degree to which measurements of a quantity vary under the same conditions, sometimes referred to as the repeatability of a measurement. 

In order to determine the precise degree of rate acceleration in the on water reactions of azodicarboxylates, we have carried out preliminary rate measurements on the reaction of quadricyclane with DEAD (Fig. 11.12). We have found that the on water reaction is nearly 86-fold faster than the reaction in toluene, and is about 20-fold faster than the neat reaction (S. Narayan and K.B. Sharpless, unpublished results). The precise mechanism of on water acceleration in the reactions of azodicarboxylates is presently unknown nevertheless, a number of observations point to the involvement of the water-hydrocarbon interface. Further studies along these lines are in progress. 

Enrichment is just one, albeit the most sensitive, stage in the transformation of the refined ore (ie, yellowcake for uranium) into fresh fuel. The enriched uranium oxide has to be fabricated into fuel to fit the reactor design for which it has been ordered. In many discussions of the problem of proliferation control, the fact that nuclear fuel is like a bespoke suit tends to be overlooked. The fuel fabricator has to take account of the precise degree of enrichment specified by the reactor operator and to set the fuel in assemblies that will deliver the most efficient neutron flux for the reactor...
