It turns out that there is another branch of mathematics, closely related to tire calculus of variations, although historically the two fields grew up somewhat separately, known as optimal control theory (OCT). Although the boundary between these two fields is somewhat blurred, in practice one may view optimal control theory as the application of the calculus of variations to problems with differential equation constraints. OCT is used in chemical, electrical, and aeronautical engineering where the differential equation constraints may be chemical kinetic equations, electrical circuit equations, the Navier-Stokes equations for air flow, or Newton s equations. In our case, the differential equation constraint is the TDSE in the presence of the control, which is the electric field interacting with the dipole (pemianent or transition dipole moment) of the molecule [53, 54, 55 and 56]. From the point of view of control theory, this application presents many new features relative to conventional applications perhaps most interesting mathematically is the admission of a complex state variable and a complex control conceptually, the application of control teclmiques to steer the microscopic equations of motion is both a novel and potentially very important new direction. 

In addition to conventional applications in conducting polymers and electrooptical devices, a number of recent novel applications have emerged. Switching of DNA electron transfer upon single-strand/double-strand hybridization fonns the basis for a new medical biosensor teclmology. Since the number of base pairs of length 20... 

Many preengineered conveyor components can be purchased off the shelf they are economical and easy to assemble, and they perform well on conventional applications (for which they are designed). However, it is advisable to check with the manufac turer to be sure that the apphcation is proper. 

One of the driving forces for so-called non-conventional applications is water usage is becoming a prime concern for many areas of the country. Impact fees for new operations and high sewer costs are common in the southern United States. 

A detailed and well-referenced account of electrochemical methods of testing has been written by Dean, France and Ketcham in a section of the book by Ailor. ASTM G5 1987 outlines standard methods for making potentiostatic and potentiodynamic anodic polarisation measurements and ASTM G3 1974 (R1981) gives conventions applicable to electrochemical measurements in corrosion testing.

The United States leads in basic research related to implantation processes and in the development of equipment for conventional applications of ion implantation. Japan appears to have the initiative in the development of equipment for ion microbeam technologies. 

To understand the extraordinary potential for DNA to be utilized as a material in construction processes, the general properties of this biomolecule will first be discussed. In addition, examples of naturally occurring nucleic acid-based nanostructures will be described that are of great importance both for cellular processes and conventional applications in molecular biotechnology. 

Post-combustion capture follows the conventional application of a specific purification unit applied for a particular pollutant removal (C02 in this case). Figure 3 illustrates a typical block diagram of the post-combustion process that offers a great feasibility and versatility in terms of operating conditions and process integration.

In October 2001, the UN International Maritime Organization (IMO) adopted the International Anti-Fouling Systems Convention (IMO, 2001). According to the convention, application of TBT-based AF paints is banned from 1 Jan 2003. Use of TBT-based AF paint is banned from 1 Jan 2008. 

To compete in this arena, biofuel cells must take advantage of inherent biocatalytic properties that cannot be duplicated by conventional technology. Among these key properties are (1) activity at low temperature and near-neutral pH, (2) chemical selectivity, and (3) potentially low-cost production using fermentation and bioseparation technologies. To the extent possible, these properties must be exploited with minimal compromise of power density and stability. This constraint leaves one major class of conventional applications suitable for biofuel cells small fuel cells for portable power. 

Although organocopper compounds are established for various organosyn-thetic transformations and simple Cu salts are widely apphed in organic syntheses [1,2], conventional applications of Cu in oxidation or oxygenation catalysis have largely been limited to a co-catalytic role. The most promi-... 

In countries where a strong environmental regulation for industrial wastewater exists, purification of waste streams from potato factories regarding both the fruit water and the pulp is required. Several attempts have been made to dehydrate the by-products and to utilize them for different purposes. Its high moisture content (80%) requires an expensive drying due to the problem of spoilage, if left untreated. The starch industry tries to sell as much pulp as possible as wet or partially dried cattle feed. However, the need for potato pulp by farmers is limited. Potato pulp is being used as cattle feed as well as a solid-state fermentation media for the production of different biomolecules. Conventional applications of potato pulp are listed in Table 16.2.

Figure 17.8—A non-conventional application of neutron activation. Neutron activation can be used to determine the composition of warheads. The drawing, reproduced by permission of EG G Ortec, demonstrates the principle of this approach. The graph represents part of a 7 spectrum obtained after only a few minutes from a warhead containing a nitrogen compound.

In this section, we describe time-resolved, local in-situ measurements of chemical potentials /, ( , f) with solid galvanic cells. It seems as if the possibilities of this method have not yet been fully exploited. We note that the spatial resolution of the determination of composition is by far better than that of the chemical potential. The high spatial resolution is achieved by electron microbeam analysis, analytical transmission electron microscopy, and tunneling electron microscopy. Little progress, however, has been made in improving the spatial resolution of the determination of chemical potentials. The conventional application of solid galvanic cells in kinetics is completely analogous to the time-dependent (partial) pressure determination as explained in Section 16.2.2. Spatially resolved measurements are not possible in this way. 

Conventional applications of fenitrothion at 210-280 g/ha have been found to sometimes induce short-lived increases in invertebrate drift and opportunistic feeding by native fish on aquatic and terrestrial invertebrates drifting in streams following spraying, but do not appear to cause significant depletion of stream bottom fauna (10, 11). Applications of dosages up to 420 g/ha fenitrothion have been found to have limited impacts on lake fauna aside from occasional short term suppression of zooplankton populations (10, 12, 13).

For operation over a limited spectral region primarily confined to the UV (200 - 350 nm), high wattage deuterium lamps are available and have been used in select applications. The emission region for these lamps is well defined, frequently encompassing approximately 1 mm. However, D2 lamps provide an output that is severely limited above 350 nm, and for operation at longer wavelengths a second source is necessary. For this reason, most conventional applications utilize a Xe or mercury-xenon arc lamp as the source of choice for CD measurements. 

Because all electrochemical devices such as batteries, fuel cells, sensors, and electrochromics require an electrolyte, the potential applications for ionic conductors are enormous. In addition to these more conventional applications, solid electrolyte materials are investigated for use as electrochemical memory devices, oxygen pumps, gas phase electrolyzers, and thermoelectric generators. ...
