Water can only be sent to storage provided the source process has taken place, this is ensured through constraint (9.53). Constraints (9.54) and (9.55) ensure that the time at which water is sent to central storage is the same time at which the water was produced.

Example Secondary kinetic isotope effects on the a-cleavage of tertiary amine molecular ions occurred after deuterium labeling both adjacent to and remote from the bond cleaved (Chap. 6.2.5). They reduced the fragmentation rate relative to the nonlabeled chain by factors of 1.08-1.30 per D in case of metastable ion decompositions (Fig. 2.18), but the isotope effect vanished for ion source processes. [78] With the aid of field ionization kinetic measurements the reversal of these kinetic isotope effects for short-lived ions (lO -lO" s) could be demonstrated, i.e., then the deuterated species decomposed slightly faster than their nonlabeled isoto-pomers (Fig. 2.17).

The initiative to develop at-source processes very often comes from an industry and emanates from internal environmental problems. The development of the process may be sponsored by the industry, government, or by private R D organizations that may be attracted by the general market potential. The incentive of installing such a process in the industry is, besides... 

The development conditions that are feasible for at-source processes are somewhat different from those of the centrally located facility regarding the freedom in feed materials and end products. This is especially characteristic for at-source processes, where the feed solution is dependent on optimal working conditions in the main process and therefore the composition is relatively constant and well defined. In addition, the product solution must have an accurate specification in order not to disturb the main production. So in the development work, a good knowledge of the main operation is necessary. 

The direct investment is relatively low for at-source processes, as they can be built in very small units. In addition, the operation costs are also comparably low because of the integration with the main operation. For example, administration costs can be almost neglected. The same is true for process supervision, especially at night, when it can be shared with the main operation. Usually, at-source solvent extraction processes have very low costs for chemicals and energy.

In Fig. 4 an overview of the chemical composition , already grouped according to source processes, of PM10 in Germany is shown. The unaccounted PM mass in these mass closures is frequently around 10-20% which can reasonably be assigned to particle bound water and analytical uncertainties. Higher unaccounted mass fractions in most cases also comprise the mineral dust fraction since analyses of silicon and aluminium are scarcely done in routine. In some studies only the main ionic PM constituents were analysed, and the unaccounted mass then became the major fraction and comprises carbonaceous particles as well.

However, some important waste classifications are based on attributes not intrinsic to the waste. A prime example is waste that is classified based on its source (process or organization), such as high-level radioactive waste and many listed hazardous chemical wastes. The undesirable effects of this are summarized previously and are not repeated here.

The main motivation for the development of the GRG coupled system was the need to account for sink and source processes, namely chemical conversion, in the assimilation of satellite observation of chemical tracers within the 4D-VAR data assimilation of the IFS. Since it appeared too costly to be costly to integrate complex chemical mechanisms in the IFS, tendencies describing sink and source processes should be provided by well established CTMs, being coupled to... 

The observed seismic data are usually bandlimited, because the frequency range is limited by the natural time constant of the source process, by receiver and survey design, by seismic preprocessing required for noise removal, etc. (see Aki and Richards, 2002, and Bleistein et al., 2001 for further discussions). The bandlimiting is an important characteristic of observed seismic data which should be taken into account, especially if we use the high frequency asymptotics for data inversion.
