Distribution of long period

Figure 8.25. The features of a primitive interface distribution function, g (x). The IDF is built from domain thickness distributions, ha (x) and hc (x), followed by the distribution of long periods, (x), and higher multi-thickness distributions...

Let us demonstrate the centrally-decorated lattice model115. The corresponding geometrical consideration for the deduction of the higher thickness distributions is somewhat involved. Figure 8.46 presents a geometrical construction scheme that helps to link both the observable distribution of long periods, hi (x), and the observ-... 

These y(r) curves were analyzed using a pseudo-two-phase structure model, which has a broad distribution of long period and lamellar thickness and a diffuse phase boundary at the interface of the crystal and the amorphous regions as shown by Figure 11.4. 

A special case of long-period structure to be considered is the oI40-AuCu(II) type structure which has ID substitutional and displacive modulations (Fig. 3.41). We must first mention that ordering of the Au-Cu face-centred cubic (cF4-Cu type) solid solution, having a 50-50 atomic composition, re-distributes Cu and Au atoms...

The fourth column shows the arrangement of long periods in the relaxed state. Up to the second order, the long periods are clear and continuous, indicating an orientation distribution of lamellar stacks that contain no more than three layers. 

Active dry yeasts of improved quality have been available for many years, and more recently instant active dry yeast has been introduced (15,20). This instant yeast exhibits more activity than regular active dry yeast due to improved drying techniques, and can replace compressed yeast at a rate of 33 —40%. Dried yeasts, which are stable for long periods of time at room temperature, are of interest to bakers because of the high distribution cost of fresh compressed yeast. This is especially tme for those away from distribution centers and for smaller bakers whose usage rate of yeast is low. 

Dislocations are known to be responsible for die short-term plastic (nonelastic) properties of substances, which represents departure from die elastic behaviour described by Hooke s law. Their concentration determines, in part, not only dris immediate transport of planes of atoms drrough die solid at moderate temperatures, but also plays a decisive role in die behaviour of metals under long-term stress. In processes which occur slowly over a long period of time such as secondaiy creep, die dislocation distribution cannot be considered geometrically fixed widrin a solid because of die applied suess. 

The life of the magnesium anodes with a current content of about 1.2 A a for 10 mA according to Table 6-4 was calculated from Eq. (6-9) as 120 years. This assumes that the protection current is equally distributed over both anodes. The calculated life would certainly not be reached because uniform anode current distribution cannot be achieved over a long period of time. It would, however, be substantially longer than the minimum required life of 25 years. For this length... 

The absorption, distribution, and accumulation of lead in the human body may be represented by a three-part model (6). The first part consists of red blood cells, which move the lead to the other two parts, soft tissue and bone. The blood cells and soft tissue, represented by the liver and kidney, constitute the mobile part of the lead body burden, which can fluctuate depending on the length of exposure to the pollutant. Lead accumulation over a long period of time occurs in the bones, which store up to 95% of the total body burden. However, the lead in soft tissue represents a potentially greater toxicological hazard and is the more important component of the lead body burden. Lead measured in the urine has been found to be a good index of the amount of mobile lead in the body. The majority of lead is eliminated from the body in the urine and feces, with smaller amounts removed by sweat, hair, and nails.
