Options exercising

Recalling that Aa = a, - a and = a, + 2a)l3, calculate the ratio a/a,. Is this value reasonable As an optional exercise, aj and could be calculated using ab initio programs such as Gaussian or Hyperchem. 

In fact, in some systems, f(F) is known to be a log-normal distribution, for which F and g2 can be transformed into a mass-mean radius and a geometric standard deviation. As an optional exercise, carry out such an evaluation. 

Note that the penetration (100 — ) has increased by a factor of 3. The reader, as an optional exercise should outline the calculational procedure to follow if the particle size distribution varies with each inlet duct. 

Select as a basis l.Olbmol of ethylene feed. The following table can then be constructed. Calculational details are left as an optional exercise. 

Diastereoisomers have two chiral centers, and those created with the compound being separated will not have the same solubilities and other properties as the original isomers. This is the most common option exercised in practice. However, it can often be quite costly, because the chiral compound being added to carry out the separation is frequently very expensive, and even in a recycle operation, it can add much cost due to material loss. 

As an optional exercise, draw a rough phase diagram for the system KCl-MgCla-HaO. 

As an example, in March 2003 bond options expiring in April, May, June, and September were all available. The first three were exercisable into the June futures contracts, while the last one was exercisable into the September futures contract. Although all four expiry dates were theoretically available, only those options exercisable into the front futures contract (the next one to mature) were liquid. On 7 March 2003, the front contract was the June 2003 future, and over 99% of all futures trades and 99.9% of bond options trades involved this contract. Exhibit 17.7 provides a breakdown of these figures, showing the total number of contracts traded on that day. 

If you completed the Optional Exercise (isolating the solid dissolved in the mother liquor), do the following ... 

If you completed the Optional Exercise, compare the distribution coefficient you obtained for caffeine with the corresponding literature value. Comment on the similarity or difference. 

Another possible case would be resistance that might be in parallel, as shown by the dashed lines in the diagram. It is not practical to measure this with the inexpensive equipment being used in this laboratory course (although the reader is encouraged to try it as an optional exercise), because the 1,000 mfd capacitor offers such a low resistance to 60 Hz ac that only a negligible effect can be seen on the scope when a 100 ohm resistor is put in parallel. (According to eqn. 9.5, this capacitor should have an effect similar to that of a 0.38 ohm resistor.)... 

The circuit of Fig. 14.7 (and the ones of Figs. 14.8 and 14.9) could be assembled by the experimenter as an optional exercise, but this would require sharing extra components with another experimenter or another laboratory group. 

Note The data presented in this table were collected in the late 1960s for a spacecraft power system. The tabulated values merely demonstrate a trend in increase in weight as a function of redundant options exercised and mission duration and must not be taken as guaranteed values for other spacecraft or communication satellite or tracking satellite. Power required for stabilization and attitude control mechanisms is significantly greater than power required for onboard electronic sensors and electrical devices.
