Special accommodations can often be made to help balance work and home. Eldercare and childcare issues are a common experience for all, says Maria Lehman, PE, Fj SCE, fice President and Director of Transportation Systems with Bergmann Associates. We must look at human heings individually and provide flexihihty to deal with life issues. ... 

If you require special accommodations in the test-taking procedure, you should contact your state licensing board office well in advance of the day of the examination so that appropriate arrangements may be determined. Only preapproved accommodations are allowed on exam day. 

Heat rejection from hot leg piping shall be controlled so that magnitude of heat transfer from piping is maintained at [2.1] kW/meter. (Derived from hot leg piping analyses) At 500 K, approximately 0.75 m of radiator area Is needed for each meter of pipe. Special accommodations must be made to transport the rejected heat to the radiator area, and minimize thermal and structural impact on nearby elements. Heat rejection approach must maintain the protection of the hot leg piping from the external threats of orbital debris and micrometeoroids. 

Charged species are not a special case in RAMSES. As ean be seen from Figure 2-57, rr-electron systems can accommodate any number of electrons between zero and two times the number of atoms involved. 

Two modifications of the duidized-bed reactor technology have been developed. In the first, two gas-phase duidized-bed reactors coimected to one another have been used by Mobil Chemical Co. and Union Carbide to manufacture HDPE resins with broad MWD (74,75). In the second development, a combination of two different reactor types, a small slurry loop reactor followed by one or two gas-phase duidized-bed reactors (Sphetilene process), was used by Montedision to accommodate a Ziegler catalyst with a special particle morphology (76,77). This catalyst is able to produce PE resins in the form of dense spheres with a diameter of up to 4—5 mm such resins are ready for shipping without pelletization. 

In North America, a special, high conductivity, low permeability, "hot-pressed" carbon brick is utilized almost exclusively for hearth walls. Because of their relatively small size and special, heat setting resin cement, and because the brick is installed tightly against the cooled jacket or stave, differential thermal expansion can be accommodated without refractory cracking and effective cooling can be maintained. Additionally, the wall thickness is generally smaller than 1 m, which promotes the easy formation of a protective skull of frozen materials on its hot face. Thus hearth wall problems and breakouts because of carbon wall refractory failure are virtually nonexistent. 

Whenever the process machine operates at the same speed as its driver, the two can be directly coupled. This direct couphng stiU allows for a variable speed, through acuustments of the speed or the driver. Steam turbine speed can be easily adjusted, and electric motor speed can also be varied by the use of special drives that vaiw the frequency of the power applied to the motor. Wdiether the speed is fixed or variable, direci coupling of two machine shafts presents the problem of accommodation of misalignment. To this purpose, machines are coupled through a.flexible coupling. 

The higher solubility of carbon in y-iron than in a-iroii is because the face-ceiiued lattice can accommodate carbon atoms in slightly expanded octahedral holes, but the body-centred lattice can only accommodate a much smaller carbon concentration in specially located, distorted tetrahedral holes. It follows that the formation of fenite together with cementite by eutectoid composition of austenite, leads to an increase in volume of the metal with accompanying compressive stresses at die interface between these two phases. 

NOx emission controls in large engines and turbines are based on the same principles. However, special designs must be applied to accommodate differences in the combustion process. Methods to control NfJ include the following. 

Equation (20.4.3) defines tlie pdf of the Weibull distribution. Tlie exponential distribution, whose pdf is given in Eq. (20.4.1), is a special case of the Weibull distribution witli p = 1. Tlie variety of assumptions about failure rate and tlie probability distribution of time to failure tliat can be accommodated by the Weibull distribution make it especially attractive in describing failure time distributions in industrial and process plant applications.
