Thermostable pectinesterases (TSPE), operationally defined as activity that survives 5 min at 70°C, contribute most to cloud loss in juices at low temperatures and juice pH (26). The percentage of total activity that is thermostable is highly variable and differs in kinetic properties, (22, 26), ease of solubilization (28, 29), stability to low pH (25) and stability to freeze-thaw cycles (23). Some of the variability in reported total PE and TSPE may be related to limitations of current methods to quantify activity. Any processing treatment or assay condition that increases cell wall breakdown or release PE from a pectin complex would enhance detection of total and TS-PE activity. Commercially, PE is inactivated by pasteurization in a plate heat exchanger or during concentration in the TASTE evaporator. 

Dynamic models operationally define and quantify the flows of patients, which represent opportunities in a given marketplace. In general, the patient flow component recreates the structure and magnitude of patient movements within a simulation environment representing an indication marketplace. This type of operational examination of market dynamics becomes a useful commercial evaluation tool. In addition, it can help inform and test key marketing strategies considered for an NCE s brand plan designed to maximize that potential. 

For successful operation a selective CO oxidation catalyst in a reformer-PEFC system must be operated at ca. 353-373 Kin a complex feed consisting of CO, 02, H2, C02, H20 and N2, and be capable of reducing CO concentrations from about 1% to below 50 ppm - this is equivalent to a CO conversion of at least 99.5% [4, 54, 60], In addition, this conversion must be achieved with the addition of equimolar 02 (twice the stoichiometric amount) and the competitive oxidation of H2 must be minimized. This is expressed as selectivity, which is defined as the percentage of the oxygen fed consumed in the oxidation of CO for commercial operation a selectivity of 50% is acceptable, since at this selectivity minimal H2 is oxidized to water. 

The dinitration route from benzazepine to varenicline was high yielding, direct, and sufficiently safe for commercial operation. These characteristics defined the process chemistry objective to enable a benzazepine synthesis for manufacturing. The preferred process route to varenicline evolved with dedicated research, however, as described below. 

From process studies carried out in this pilot plant over several years, parameters were defined to permit process and engineering designs of full commercial operations. Process economics indicated the cost of this active carbon would be greater than currently available commercial carbons. However, hundreds of evaluations in a full spectrum of applications showed that this active carbon would be competitive in many of those applications on a cost-performance basis. It will be commercially available mid-85 in various forms, trademarked as SUPER-A, from Anderson Development Company in Adrian, Michigan,... 

To prevent hot spot occurrence, we evaluated the methods which improved liquid distribution, in the commercial operations. Figure 6 compares changes in the temperature deviation of the first bed during the different runs. The axial number, which is an average of the standard deviation of the temperatures at each level, is defined as an index of a degree of maldistribution. A small number indicates good liquid distribution. We took the countermeasures successively run after run. 

The second stage of development is typically aimed at mimicking commercial operations by employing recycle streams to achieve realistic simulations of the integrated process. Isothermal conditions are usually maintained in the reactor, but if heat release is a concern, such as residuum hydrotreating, then it is wise to run adiabatically so that the adiabatic reaction temperature can be established and also how much heat must be removed in the final commercial design. Defining catalyst deactivation, yield patterns, and how various feed types influence the process are typical aspects to explore. 

The French fast reactor prototype Phenix, located at Marcoule in the Card department, was put into commercial operation in 1974. The total time of power operation of the plant is approximately 100 000 hours. The initial objective of Fast Breeder Reactor demonstration has been achieved. Since the mid-nineties, the role of the reactor as an irradiation facility has been enqjhasized, particularly in support of the CEA s transmutation R D programme in the context of the 30 December 1991 French law on long-lived radioactive waste management. This new objective has required the extension of the planned reactor lifetime. A renovation programme was defined based on ... 

It should be remembered that the sample pH is operationally defined and as a consequence it is not possible to define how accurate the measured pH is. Clearly, the reliability of the pH estimate depends on the accuracy and precision of the preparation of the tris buffers. A precision of 0.01 pH imit is attainable with commercially available reference half cells without extra precautions, and down to 0.002 if special care is taken to design a free flow liquid junction (Culberson, 1981 Butler et al., 1985 Covington and Whitfield, 1988). 

Although particle characterization is not an ordinary instrumentation issue, some supporting laboratory scale equipment helps even the commercial operation by defining the realistic nature of the particles in each occasion. Thus it is recommended to have a small, say 5 cm in diameter, cold test unit with a flowmeter and pressure sensors. 

The standards for tests, which are cited in reference to the standards for characteristics. In order for a client and his supplier to compare their results during a commercial transaction, it is important that their laboratories rigorously follow the same operating procedures. The procedures are thus precisely defined in the standards. 

From the standpoint of a military product, system effectiveness is the probabiUty that the system meets successfully an operational demand within a given time when operating under specified conditions. From the standpoint of commercial products, system effectiveness is harder to define, but basically means customer satisfaction. There are several system parameters that are important to the customer. Some of these parameters are defined below. 

Because of limited commercial experience with anode coatings in membrane cells, commercial lifetimes have yet to be defined. Expected lifetime is 5—8 years. In some cases as of this writing (ca 1995), 10-years performance has already been achieved. Actual lifetime is dictated by the membrane replacement schedule, cell design, the level of oxygen in the chlorine gas, and by the current density at which the anode is operated. 

Nuclear Waste. NRC defines high level radioactive waste to include (/) irradiated (spent) reactor fuel (2) Hquid waste resulting from the operation of the first cycle solvent extraction system, and the concentrated wastes from subsequent extraction cycles, in a faciHty for reprocessing irradiated reactor fuel and (3) soHds into which such Hquid wastes have been converted. Approximately 23,000 metric tons of spent nuclear fuel has been stored at commercial nuclear reactors as of 1991. This amount is expected to double by the year 2001.
