Operational Constraints and Problems. Synthetic ammonia manufacture is a mature technology and all fundamental technical problems have been solved. However, extensive know-how in the constmction and operation of the faciUties is required. Although apparendy simple in concept, these facihties are complex in practice. Some of the myriad operational parameters, such as feedstock source or quaUty, change frequendy and the plant operator has to adjust accordingly. Most modem facihties rely on computers to monitor and optimize performance on a continual basis. This situation can produce problems where industrial expertise is lacking. 

Unvulcanized Latex and Latex Compounds. A prime consideration has to be the fluid-state stabihty of the raw latex concentrate and hquid compound made from it. For many years, the mechanical stabihty of latex has been the fundamental test of this aspect. In testing, the raw latex mbber content is adjusted to 55% and an 80 g sample placed in the test vessel. The sample is then mechanically stirred at ultrahigh speed (ca 14,000 rpm) by a rotating disk, causing shear and particle cohision. The time taken to cause creation of mbber particle agglomerates is measured, and expressed as the mechanical stabihty time (MST). 

Fundamental Property Relation. The fundamental property relation, which embodies the first and second laws of thermodynamics, can be expressed as a semiempifical equation containing physical parameters and one or more constants of integration. AH of these may be adjusted to fit experimental data. The Clausius-Clapeyron equation is an example of this type of relation (1—3). 

All turbines are variable-speed drivers and operate near or above one of the rotor s critical speeds. Narrowbands should be established that track each of the critical speeds defined for the turbine s rotor. In most applications, steam turbines operate above the first critical speed and in some cases above the second. A movable narrowband window should be established to track the fundamental (1 x), second (2x), and third (3x) harmonics of actual shaft speed. The best method is to use orders analysis and a tachometer to adjust the window location. 

Luzius Dettli was not only the first who described the linear function for the dependence of diug elimination on glomerular filtration rate. He was also the first who proposed the fundamental dose adjustment recommendation, the proportional dose reduction rule. Two alternatives are given to either reduce the single dose (D) or extend the interval (Tau). 

Ideally, a mathematical model would link yields and/or product properties with process variables in terms of fundamental process phenomena only. All model parameters would be taken from existing theories and there would be no need for adjusting parameters. Such models would be the most powerful at extrapolating results from small scale to a full process scale. The models with which we deal in practice do never reflect all the microscopic details of all phenomena composing the process. Therefore, experimental correlations for model parameters are used and/or parameters are evaluated by fitting the calculated process performance to that observed. 

During their passage through the column, sample molecules spend part of the time in the mobile phase and part in the stationary phase. All molecules spend the same amount of time in the mobile phase. This time is called the column dead tine or holdup time (t.) and is equivalent to the tine required for an unretained solute to reach the detector frsolute retention time (t,) is the time between the instant of saiq>le introduction and when the detector senses the maximum of the retained peak. This value is greater than the column holdup time by the amount of time the solute spends in the stationary phase and is called the adjusted retention time (t, ). These values lead to the fundamental relationship, equation (1.1), describing retention in gas and liquid chromatography. 

The random error arises from the measurement of y the true value of which is not known. The measurements are assumed to be free of systematic errors. The modeling equations contain adjustable parameters to account for the fact that the models are phenomenological. For example, kinetic rate expressions contain rate constants (parameters) the value of which is unknown and not possible to be obtained from fundamental principles. 

Raff Not necessarily. In poodles, for example, differences in size between miniatures, toys and regulars apparently mirror levels of insulin-like growth factors (IGFs). To me that is not especially interesting. We know that if you put in more growth hormone (GH) or IGF, you get a proportionally bigger animal. What interests me more is how a few hundred cells in a limb primordium know what the approximate final size of the limb should be. This seems to me to be a more fundamental question than how growth hormones adjust the final size of an animal. 

To summarize, it should be highlighted that in general terms the issue of prescribing incentives is approached with a marked lack of consideration of such fundamental concerns as their impact on health, although this aspect is indirectly addressed by non-financial incentives and mixed formulas such as those discussed above. Financial incentives alone appear to lack effectiveness as instruments of pharmaceutical policy. Incentives aimed at prescribers should under no circumstances create a clash of interests between their fees and the quality of the care they provide for their patients, and therefore adjustment must be made in these terms. In turn, we cannot ignore that the effect of this type of mechanism on physicians behaviour will depend on, among other factors, the quality of available information on the aspects taken into consideration in their application. 

Forecasting revenues fundamentally rests on models plus judgment. More formal methods project the trends of past revenues into the future adjusting for known or expected fluctuations. Typical models employed are... 

A wide range of operating conditions and design philosophies affect mercury cell efficiency. For example, the fundamental distinction between a resaturation and a waste brine process influences the temperature and brine strength profile along the length of the cell and hence the overall efficiency. Another important factor is the quality of the brine. Impurities in the brine can cause base-plate deposits, which tend to reduce the anode/cathode gap. This gradual reduction in gap requires either manual or automatic adjustment and, eventually, the cell must be taken off-line and the thick mercury removed.
