Characteristic defined

Eigure 11 shows a schematic and collector characteristics for a common emitter n—p—n transistor circuit. The load line crossing these characteristics shows the allowed operation of the transistor with a supply voltage, = 12 V a load resistor, 7 = 2 and a bias resistor, 7 g = 20 kQ. The load line corresponds to the equation = 7 7 -H. Plotting the load line on the collector characteristics defines BJT behavior 0.6 V is required... [Pg.351]

Detectors are usually conpued in terns of their operational characteristics defined by the nininvin detectable quantity of standards, the selectivity response ratio between standards of different conpositlon or structure, and the range of the linear portion of the detector-response calibration curve. These terns are wid. y used to neasure the perfomance of different chronatographic detectors and were fomally defined in section 1.8.1. [Pg.135]

The rate of bubble collapse Rcl is primarily important in the first transition zone where the bulk liquid is subcooled. A number of studies have been published on subcooled boiling as well as the prediction of the point of net vapor generation, characteristics defining Transition Zone I, and the onset of nucleation. These studies all result in empirical correlations, and have not led to quantitative conclusions which can be generalized. The radial velocity... [Pg.41]

Each step in dendrimer synthesis occurs independent of the other steps therefore, a dendrimer can take on the characteristics defined by the chemical properties of the monomers used to construct it. Dendrimers thus can have almost limitless properties depending on the methods and materials used for their synthesis. Characteristics can include hydrophilic or hydrophobic regions, the presence of functional groups or reactive groups, metal chelating properties, core/shell dissimilarity, electrical conductivity, hemispherical divergence, biospecific affinity, photoactivity, or the dendrimers can be selectively cleavable at particular points within their structure. [Pg.346]

This formula is derived in Appendix 3). With regard to various cubic and quartic anharmonic interactions, the quantity ft is characterized by a certain combination of these anharmonic contributions and becomes dependent on k (see Eq. (4.3.14) for a related quantity and Ref. 140). However, this dependence is insignificant compared to the k-dependence appearing in the denominators of Eqs. (4.3.32) and (4.3.34). Therefore, spectral characteristics defined by formulae (4.3.32) can with good reason be regarded as proportional to certain functions of lateral interaction parameters and of the resonance width 77 ... [Pg.116]

If we try to refine the adequacy between the measurement procedures and the practical needs for wastewater quality monitoring, different metrological (analytical) characteristics have to be considered, such as detection limit, reliability and robustness (Table 3). Even if it is very difficult to compare the analytical methods carried out in the laboratory with on-site measurements (with on-line or tests kits), this presentation points out the main features of the measurement required for different needs. These characteristics define the quality of the available information [3], which constitutes one of the major problems that... [Pg.248]

The unit cell is defined by the lengths (a, b, and c) of the crystal axes, and by the angles (a, f>, and y) between these. The usual convention is that a defines the angle between the b- and c-axes, p the angle between the a- and c-axes, and y the angle between the a- and 6-axes. There are seven fundamental types of primitive unit cell (whose characteristics are provided in Table 7.1), and these unit cell characteristics define the seven crystal classes. If the size of the unit cell is known (i.e., a, (i, y, a, b, and c have been determined), then the unit cell volume (V) may be used... [Pg.187]

The surface normal h is constant along the characteristics, and therefore the surface velocity v(h) is constant as well (see Exercise 14.5). The characteristics, defined as... [Pg.351]

The authors of this book started working on chemical kinetics more than 10 years ago focusing on investigations of particular radiation - induced processes in solids and liquids. Condensed matter physics, however, treats point (radiation) defects as active particles whose individual characteristics define kinetics of possible processes and radiation properties of materials. A study of an ensemble of such particles (defects), especially if they are created in large concentrations under irradiation for a long time, has lead us to many-particle problems, common in statistical physics. However, the standard theory of diffusion-controlled reactions as developed by Smoluchowski... [Pg.3]

The a value for a ZnO varistor is 15 and ki = 9.3 x 10 31i, the potential dilference and current being measured in volts and amps respectively. Calculate the p.d. across the varistor for currents of 0.1, 1, 10, 100 and 1000 A. If a device needs protection against transient voltages in excess of 300 V, show how a varistor having the characteristic defined above can be connected to afford protection.

Many variations of these processes exist with the aim of controlling particle surface area, shape, and purity these characteristics define the fire retarding performance of magnesium hydroxide fillers, especially in more demanding applications where processability and good mechanical properties are also important considerations. In more recent developments, nanosize magnesium hydroxide variants have also been produced. [Pg.166]

The dinitration route from benzazepine to varenicline was high yielding, direct, and sufficiently safe for commercial operation. These characteristics defined the process chemistry objective to enable a benzazepine synthesis for manufacturing. The preferred process route to varenicline evolved with dedicated research, however, as described below. [Pg.237]

If the pore space of the support is filled with the same solvent as the impregnation solution, prior to being placed in contact with the latter, the characteristics defined above are valid only for the first phase of saturation by the solvent. [Pg.160]

The four main types of HPLC techniques are NP, RP, lEX, and SEC (Section 1.2). The principal characteristic defining the identity of each technique is the dominant type of molecular interactions employed. There are three basic types of molecular forces ionic forces, polar forces, and dispersive forces. Each specific technique capitalizes on each of these specific forces ... [Pg.10]

In summary, the wide rectangular profile is characterized by two concentration shocks, at times and fR,2/ for the first and the second component, respectively, by a residual of the injection plateau, and by a concentration plateau at C having a length At2- These characteristics define the three zones of the elution chromatogram of a binary mixture (Figure 8.1) the pure first component zone, the mixed zone, and the pure second component zone. Analytical solutions are provided to calculate the individual band profiles for a binary mixture. Table 8.1. We now study the elution profile of a narrow injection pulse, when Eq. 8.36 is no longer verified. [Pg.401]

Figure 9.5. In forming these clusters, a target diameter of 0.50 was set for each cluster in the final solution. The diameter reflects the strength of association within the cluster. Because the similarity data are frequencies of co-occurrence, a diameter of 0.50 means that each item in a cluster was associated with every other item in the cluster at least 50% of the time (i.e., by 50% of the students). This percentage reflects much better than chance performance in grouping the items and provides a strong test of how well students learned the necessary characteristics defining the situations. It also provides evidence that the characteristics were learned by a substantial number of students in relatively uniform ways. Figure 9.5.
