Trace generation

An early attempt for ordered growth of a chalcogenide simple compound has been the cathodic deposition of thin (3 p,m) CdTe films on n-type (100) GaAs single crystals from an acidic aqueous electrolyte at 95 °C, which contained Cd(II) and Te traces generated electrolytically in situ by using a pure Te anode [4]. The... 

Figure 3-22 Resonance Raman spectra of 0=Fe(IV)(TMP) (top trace) and its 180 isotope analogue (bottom trace), generated at -40°C by electrooxidation of Fe(III)(TMP)(OH) at 1.2V in CH2CI2 containing OFI and 18OH, respectively. Both spectra were obtained in situ via backscattering from the low-temperature Raman spectroelectrochemical cell using 406.7 nm excitation ( 50mW) and 8cm slit widths.

Figure 6. Iontophoretic application of acetylcholine (Ach) and pyrantel (a) Comparison of inward currents (upper trace) generated by the iontophoresis of Ach and pyrantel from a double-barrelled micropipette, b) Interaction of Ach and pyrantel showing reversible block of Ach currents following pyrantel application. The micropipette was placed within a distance of 50 urn from the bag membrane. Ejection currents of 250 nA for 1s were used. Vertical calibration 20 nA, membrane current. 400 nA, iontophoretic current (lower traces). (Adapted with permission from Ref. 2 Copyright 1985, Society of Chemical Industry).

The graph shown in Figure 1 details the results from rope whip calculations of hoisting a full load at full speed from a depth of 2000 metres below the tip. By inspection it can be seen that the solid purple trace (generated by the LeBus rope layering effects) meets the Solid blue trace (the second harmonic of the fundamental rope transverse resonant frequency) just at the... 

Extracted-Ion Chromatogram A chromatographic trace generated by considering the measured intensity of the signal for an ion with a chosen m/z value. The area of a chromatographic peak of an ion increases with its increased concentration in a sample and can be used for relative quantitation. 

Note that the expansion phase of synthesis may be likened to trace generation, while the reduction phase of synthesis may be likened to trace generalization. 

Line start-incremental monitoring system centrifugal disk photosedimentometers yield direct information on the largest and smallest fineparticle present in system. They can be operated in the fingerprint mode that is, the pen recorder traces for good and bad powders in a quality control situation can be established and compared directly to the traces generated by powder samples taken from production run. 

The pencil hardness test is perhaps the simplest form of hardness test and it is the most common hardness test applied to coatings. Pencils are pushed into the sample and the coating hardness is identified by the trace generated. The Elcometer 3080 pencil hardness tester (Fig. 2.22) is supplied with a stand and a series of 14 pencils ranging from 6B (softer) to 6H (harder). This test is an abrasion test, but it is a measure of the coatings abrasion of the pencil lead, not vice versa. 

The GC reports consist of a list of retention times and intensities (or areas). The GCO comments can be merged with the GC report to give a concise report. The algorithm used is simple (Fig. 2) comments made are associated with the previous peak. Not all the peaks detected by the flame ionization detector (FID) are responsible for an odor. So correlating GC reports and comments made requires an external trace generated by the panehst, as he or she smelled the peaks. This odor intensity trace (odorogram) is used to...
