Common time

The significance of these numbers is seen as follows.The average values of A log t are to be added to the log t values at 126 or 130°C to superimpose the latter curves on the one measured at 128°C. Since these values are added to log t values, the effect is equivalent to multiplying the individual t values at 126 and 130°C by the appropriate antilogs to change the time scale in the individual runs to a common time scale. Using the case of 6 = 0.5 as an illustration, we see the following times are required to reach this level of crystallinity ... [Pg.232]

If money is borrowed, interest must be paid over the time period if money is loaned out, interest income is expected to accumulate. In other words, there is a time value associated with the money. Before money flows from different years can be combined, a compound interest factor must be employed to translate all of the flows to a common present time. The present is arbitrarily assumed often it is either the beginning of the venture or start of production. If future flows are translated backward toward the present, the discount factor is of the form (1 + i) , where i is the annual discount rate in decimal form (10% = 0.10) and n is the number of years involved in the translation. If past flows are translated in a forward direction, a factor of the same form is used, except that the exponent is positive. Discounting of the cash flows gives equivalent flows at a common time point and provides for the cost of capital. [Pg.447]

At EA of a shot of mass 5 g for deriving alloy with usage US by intensity of 9 W/cm there ai e enough 10 minutes of handling. The common time EA depends on furnace efficiency, and in our works compounded 15-25 minutes. [Pg.291]

This is the governing equation of the Maxwell Model. It is interesting to consider the response that this model predicts under three common time-dependent modes of deformation. [Pg.86]

This is the governing equation for the Kelvin (or Voigt) Model and it is interesting to consider its predictions for the common time dependent deformations. [Pg.88]

Table 1-8 lists the transforms of some common time-variable expressions. [Pg.48]

The meter will also have a control for the time constant for the display (i.e. the speed of the meter response), and the two common time constants are Fast and Slow . Others may have an impulse and peak hold facility. More complex meters incorporate Leq-measuring devices, and these are also available as hand-held Type 1 meters with filters as in the basic meter. [Pg.654]

First order kinetics describes the most common time course of drug elimination. The amount eliminated within a time-interval is proportionate to the drug concentration in the blood. [Pg.506]

Some common time constants, relating to particular chemical engineering flow applications, are... [Pg.90]

Probably the least flexible of all methods with respect to the time-step and distance relationship is the method of characteristics (MOC). It requires the pipe lengths in a network to be adjusted to satisfy the condition of a common time interval, but provides an accurate solution of the differential equations. MOC has been successfully implemented by Goacher (G4), Streeter and associates (S6), and Masliyah and Shook (M5). More recently,... [Pg.192]

In order to ensure that the heat-integrated units are active within a common time interval, the following con constraints is necessary. In constraints (10.18), unit j has a relatively longer duration time than unit j. If duration times are equal, then constraints (10.19) and (10.20) are necessary. [Pg.226]

As each component exits the chromatographic column, it is channeled into an infrared (IR) gas cell and the component s IR spectrum obtained. A thermal conductivity detector (TCD) (see Chapter 13) can be used to determine when a component is emerging from the column. The TCD detector does not destroy the sample and none of the common gases used in GC have IR spectra, and thus do not interfere with the spectrum of eluting components. Half-peak height is a common time to obtain the spectrum of that component and the setup for detection and obtaining the spectrum can thus be automated [6,13],... [Pg.331]

Trend analysis methods are a variation on the theme of regression testing. In the broadest sense, the methods are used to determine whether a sequence of observations taken over an ordered range of a variable (most commonly time) exhibit some form of pattern of change (either an increase-upward trend or decrease-downward trend) associated with another variable of interest (in toxicology, some form or measure of dosage and exposure). [Pg.938]

This level provides the most information-rich correlation. It represents a point-to-point relationship between in vitro dissolution and the in vivo input rate of the drug from the dosage form. A linear regression of dissolution and absorption at common time point is established. In such a correlation, the linear relationship of absorption vs. dissolution with a slope of one, an intercept of zero, and a coefficient of determination of... [Pg.343]

The broad tunability of the Ti sapphire laser accounts for its ability to produce extremely short pulses when modelocked several companies produce models with specified femtosecond pulsewidths. While shorter pulses are, to a first approximation, better, there are some additional tradeoffs to be borne in mind. First, with very few exceptions all common time-resolved fluorescence experiments may be carried out... [Pg.156]

At the end of Phase 2, the FDA and sponsors try to come to an agreement on how the large-scale studies in Phase 3 should be done. How often the FDA meets with a sponsor varies, but this is one of two most common meeting points prior to submission of a new drug application. The other most common time is pre-NDA—right before a new drug application is submitted. [Pg.244]

The pre-NDA period, just before a new drug application (NDA) is submitted. A common time for the FDA and drug sponsors to meet. [Pg.248]

This instrument is used to measure the flow of clean liquids and involves the determination of the time required for an acutely angled, high frequency pressure wave to reach the opposite wall of a pipe. The elapsed time depends upon the velocity of the liquid u(, whether the pressure wave is moving with, or against the flow and upon the speed of sound in the liquid us. The most common time-of-flight meter is the counter-propagating type in which two transducers are placed on opposite sides of the liquid stream as shown in Fig. 6.3. [Pg.443]

Both models, (a) and (b), can formally be described by means of Fick s second law with a suitable common time boundary and the corresponding space boundaries, as shown in Fig. 16. Since the diffusion of the P-mer from the sol into the gel can be assumed as one-dimensional according to the column geometry and, in addition, the laterally diffusing macromolecules have all the same probability to reach the gel layer from the position c(0) of the sol at t = 0 (spontaneous diffusion of the P-mer from the sol into the gel), the second Fick s law... [Pg.29]
