The oxide layer would be unprotective if the ratio is less than unity because the film that forms on the metal surface is porous and/or cracked. Conversely, the metals with the ratio higher than 1 tend to be protective because they form an effective barrier that prevents the gas from further oxidizing the metal.
A higher P/B ratio implies that investors expect management to create more value from a given set of assets, all else equal (and/or that the market value of the firm's assets is significantly higher than their accounting value). P/B ratios do not, however, directly provide any information on the ability of the firm to generate profits or cash ...
An odds ratio of 1 indicates that the condition or event under study is equally likely to occur in both groups. An odds ratio greater than 1 indicates that the condition or event is more likely to occur in the first group. And an odds ratio less than 1 indicates that the condition or event is less likely to occur in the first group.
In this diagram the 204 Pb/ 206 Pb ratio (the reciprocal of the normal ratio) is plotted on the x-axis, so that a point on the y axis (zero 204 Pb/ 206 Pb) would have infinitely radiogenic Pb. The ratio plotted on this axis is the 207 Pb/ 206 Pb ratio, corresponding to the slope of a normal Pb/Pb isochron, which yields the age. The most ...
The graph may be plotted on a natural logarithmic scale when using odds ratios or other ratio-based effect measures, so that the confidence intervals are symmetrical about the means from each study and to ensure undue emphasis is not given to odds ratios greater than 1 when compared to those less than 1. The area of each square is proportional ...
The continental crust has become enriched with those elements relative to the mantle and thus more He 4 is produced in the crust than in the mantle. The ratio (R) of 3 He to 4 He is often used to represent 3 He content. R usually is given as a multiple of the present atmospheric ratio (Ra). Common values for R/Ra: Old continental crust: less than 1
A hotel worker accused of supplying drugs to Liam Payne before the One Direction singer’s death in Buenos Aires on Oct. 16., 2024 has reportedly turned himself in to the police.. Ezequiel David ...
This shows that the free energy of a reaction is just an alternative way of expressing the disequilibrium ratio and as such gives a more intuitive interpretation of free energy. That is if the free energy for a reaction is less than zero then it indicates that ρ < 1 {\textstyle \rho <1} and hence v r < v f {\textstyle v_{r}<v_{f}} , i.e the ...
