Y-axis range

Figure 1 shows a positive static SIMS spectrum (obtained using a quadrupole) for polyethylene over the mass range 0—200 amu. The data are plotted as secondary ion intensity on a linear y-axis as a function of their chaige-to-mass ratios (amu). This spectrum can be compared to a similar analysis from polystyrene seen in Figure 2. One can note easily the differences in fragmentation patterns between the...

A mass spectrum is a graphic representation of the ions observed by the mass spectrometer over a specified range of m/z values. The output is in the form of an x,y plot in which the x-axis is the mass-to-charge scale and the y-axis is the intensity scale. If an ion is observed at an m/z value, a line is drawn representing the response of the detector to that ionic species. The mass spectrum will contain peaks that represent fragment ions as well as the molecular ion (see Figure 1.3). Interpretation of a mass spectrum identifies, confirms, or determines the quantity of a specific compound. 

The Y-axis represents the magnitude of the friction signal force and the X-axis is the load. The slope of the trend line is dehned as the friction factor (friction force signal/load) which is used to express the relative friction coefficient (friction force/load). Experiments that have been done in the same monolayer L-B him but different scan ranges give similar results as shown in Fig. 24 and Fig. 25. The friction factors of this monolayer L-B him, 0.0265 and 0.0203, are similar. The topographies of these two areas are shown in Fig. 26. 

The x-axis in a plot of a membership function represents the universe of discourse. This is the complete range of values that the independent variable can take the y-axis is the membership value of the fuzzy set. 

Remember that each Y axis can have only one range of values. This means that you must choose the ranges so that similarly sized values are located on the same axis. Choose the right axes in Graph/Choose Variables. 

Note that the x axis is logarithmic to allow a wide range of frequencies to be shown. The y axis is the current threshold at which adverse physiological events (dysrhythmias etc.) may occur. The highest risk of an adverse event occurs at current frequencies of around 50 Hz, which is the UK mains frequency. At diathermy frequencies, the threshold for an adverse event is massively raised. 

ABC Line AB represents a respiratory acidosis as the Paco2 has risen from 5.3 to 8kPa. Compensation is shown by line BC, which demonstrates retention of HC03. The rise in HC03 from 28 to 38mmol.l 1 (y axis) returns the pH to the normal range. 

By 1965, our laboratory had developed the ability to measure blood levels of 302196. Its relative lack of potency made the test dosage range higher, creating more easily detectable blood concentrations. In this graph (Fig. 56), NF scores (right y-axis) are inverted to make the parallelism between blood level (left y-axis) and performance more apparent. 

THC levels, drawn at hourly intervals starting 20 minutes after smoking, were highly variable, as shown by the large standard deviation (which appears quite small when plotted on a logarithmic y-axis). The actual range of all THC values was from 3 to 220 ng/ml (no doubt reflecting major differences in the rate and depth of...

NMA adsorbed on x = 0.5 (gray traces) is shown for reference. On all panels 2100-1700 cm-1 range is multiplied on y-axis for clarity.

Figure 6. Heat map of a small cluster of related antihistaminic drugs. 149 pharmacological assays are clustered on the X-axis and 10 compounds are clustered on the Y-axis. Clustering is performed using Pearson correlation and complete linkage using a pICso data set. For nonhits with primary screening % inhibition values of less than 20%, a default pICso value of 3.5 was used. Non-hits and above 20% inhibition received a default pICso value of 4.0. The pICso values range from the default value of 3.5 (blue-green) to 9 (red). Black spaces indicate data that is missing due to compound interference with the detection method.

The motional dynamics of O J adsorbed on Ti supported surfaces has been analyzed over the temperature range 4.2-400 K in a recent paper by Shiotani et al. (66). Of the several types of 02, a species noted as 02 (III), and characterized by gxx = 2.0025, gyy = 2.0092, g12 = 2.0271 at 4.2 K, exhibited highly anisotropic motion. While gxx and gzz varied with increasing temperature and were accompanied by drastic line shape changes, gyy was found to remain constant. This observation indicates that the molecular motion of this 02 can be described by rotation about the y axis perpendicular to the internuclear axis of 02 and perpendicular to the surface with the notation given in Fig. 4. The EPR line shapes were simulated for different possible models and it was found that a weak jump rotational diffusion gave a best fit of the observed spectra below 57.4 K, whereas some of the models could fit the data above this temperature. The rotational correlation time was found to range from 10 5 sec (below 14.5 K) to 10 9 sec (263 K), while the...
