The Data Reduction Function provides online reports of analytical results immediately after the analysis is complete, but we also provide direct access to this function for the user who wants to reduce his data In a different way. 

The control path for the data reduction functions is depicted in Figure 4, which is an expanded view of the "Reduce Data" Block in Figure 2. The mainline functions provide a direct path from the raw data to a finished result with a minimum amount of input from the user. The functions in the right hand column are used mainly to make minor changes in the parameters controlling interactive data reduction. 

Finally, Azzena reported on the reductive functionalization of hexahydio-oxazolo[3,4- ] pyridine 193 its reaction with potassium or lithium and naphthalene followed by trapping of the intermediate organolithium derivative allowed for the isolation of piperidine 194 with useful levels of selectivities (Scheme 55) <2002J(P1)360>.

For practical photoinduced synthetic biocatalyzed transformations, it is important to integrate biocatalysts in immobilized matrices that allow the recycling of the photosystems. The fact that bipyridinium sites act as electron mediators for various redox enzymes was used to develop two paradigms for the electrical contacting and photoactivation of the biocatalyst (Figure 39). By one approach, the bipyridinium electron relays are tethered by covalent bonds to the protein backbone (Figure 39A). These electron relays act as oxidative quenchers of the excited state of the dye and, upon photoreduction of the electron acceptor units, they act as electron carriers that activate the reductive functions of the enzyme. As an example, the... 

Sulfoxide Reduction. Reduction of the sulfoxide of the mercapturic acid of 2-chloro-f+-isopropylacetanilide by Intestinal microflora has been shown in vitFo (9), but has not been demonstrated to occur in tissues. The excretion of this mercapturate sulfoxide, which is excreted into the intestine with the bile, in feces from germfree rats dosed with the acetanilide is vivo evidence for the reductive function of the intestinal microflora (49) in MftP catabolism. This reduction, in addition to deacetylation, is another source for cysteine conjugates which can be translocated to the tissues for metabolism or excretion, or remain in the intestine and further catabolized by the microflora. 

Other work has shown that Pt Rh are more S resistant than Pd [3,13], and also more Pb resistance than Pd [6,12-14], Our hypothesis proposes that Pb will form Pb-S-Pd compounds which deactivate the Pd activity, during aging. Because the NOx reduction is greatly dependent on the Pd dispersion, and is effective only when Pd particles or the available Pd surface active sites are close to each other, any steric hinderance generated on the Pd surface that would block the N-N bond formation will compromise the NOx reduction activity. When the Pb-S-Pd compound is formed, illustrated hypothetically below, the closeness of two NOx molecules required so that the N-N bond can be formed (N0+N0->N>+02) is no longer feasible. Consequently, the NOx reduction function of the Pd catalyst is hindered by the physical steric effect. Since neither HC or CO oxidations require formation of a C-C bond, or the proximity of two same molecules, to complete their reactions, the Pb-S-Pd compound intereference is therefore less predominant.
