Post-Processing Effects

For an effective control operation, the transducer with orthogonal coils has been coupled to a SFT 6000N control equipment, the results being sampled and quantized on 12 bits, stored and post-processed. 

Post-processing, n - performing a mathematical operation on an intermediate analysis result to produce the final result, including correcting for temperature effects, adding a mean property value of the calibration model, or converting the instrument results into appropriate units for reporting purposes. 

A large field experiment (about 0.7ha) was established in the area of a former spill, after the removal of bulk of the contamination. Hemp and flax cultivars were planted in May 2002 and 2003, and after harvest, the plant material was treated with the standard technological process for fibre production at Agritech Ltd. The activity of accumulated Ra was determined in various parts of the plant. As all plants tested showed a level of activity indistinguishable from background, they were effectively non-radioactive (Table 4). Post-processing products similarly contained no Ra activity (Table 5). 

Method 2. Saturation Method for Sequential Pumping. In this method, atomic fluorescence of the inorganic probe is produced at 3+1 and at 3+2 after excitation at 1+3 and/or 2+3 respectively. However, in this case, it is necessary to "saturate" the excited level, 3, in order to use the methodic In addition, in order for the flame temperature to be evaluated it is necessary for the mixing first order rate constant, k2i, between the metastable, 2, and ground state, 1, to be much greater (> 20X) than the sum of the total deactivation rate constants between levels 3 and 1 and also between 3 and 2. This method also requires calibration of the spectrometric measurement system, saturation of level 3, corrections or minimization of scatter and post filter effects, and beam matching of 2 dye laser beams are needed for the excitation process. 

The recovery experiment carried out for this assay resembles somehow the sum of two potential effects The loss of compound during the sample preparation process (in this case on-line extraction) and a potential matrix effect during sample analysis. However, since an online sample clean up procedure is used here, these two potential effects cannot be separated in the usual way (One experiment would be the comparison of a processed spiked plasma sample with a blank plasma sample spiked post sample processing in order to determine the recovery of the sample preparation step. In a second experiment, again a processed blank plasma sample would be spiked post processing and the result would be compared with the response of a spiked solvent sample in order to reveal a potential matrix effect during analysis). 

The NONMEM (nonlinear mixed-effects modeling) software (Beal et al. 1992), mostly used in population pharmacokinetics, was developed at the University of California and is presently distributed by Globomax. For data management, post processing and diagnostic plots, the software S-plus (Mathsoft) is frequently used. 

Strictly speaking, some post-photochemical effect is present even in systems in which there are no secondary processes, since, as previously mentioned, there is always some delay between the absorption of a photon and the appearance of its chemical or physical consequences. However, the term "post-photochemical effect" is usually reserved for the effect of secondary thermal reactions. 

As mentioned in Chapter 1, a complete CMP process sequence will end with an effective cleaning process, leaving the planarized surface defect and contamination free and ready for the next step in the device/circuit fabrication sequence. By microelectronic fabrication standards, CMP is an inherently dirty process. Effective post-CMP cleaning is mandatory to achieve a high yield IC process. In this chapter we shall review the defect generation and cleaning.
