Loops editing

However, the conditions are often far from those of industrial situations. In order to better simulate solvent degradation during the PUREX process, a test loop was created in the 1990s in a CEA laboratory (Fontenay-aux-Roses, France), with the EDIT loop (Extraction Desextraction Irradiation Traitement) (21, 22). The laboratory simulation of industrial conditions consisted of a succession of representative physical and chemical treatments after the irradiation of the solvent (i.e., alkali and acid treatments, distillation). Indeed, these treatments can modify the final solvent composition because of the elimination of some compounds or the occurrence of secondary reactions. A few years later, the MARCEL (Module Avance de Radiolyse dans les Cycles d Extraction Lavage) test loop was built at Marcoule to follow the regeneration efficiencies of degraded solvents involved in actinide separation processes (4, 5). 

Line 1 clears the screen and requests the input of the burst pressure of the vessel. Line 2 sets gamma to 1.4 and the absolute temperature to 300. If your pressure or temperature is different, edit the program Line 3 requests the molecular weight of the gas in the vessel. Lines 5-10 loop to perform the iteration. Line 6 iterates I ... 

The default is a proportional controller, but the K block in Fig. M6.1 can easily be changed to become a PI, PD, or PID controller. The change can be accomplished in different ways. One is to retrieve the compensator-editing window by clicking on the K block or by using the Tools pull-down menu. The other is to use the set of arrow tools in the root locus window to add or move open-loop poles and zeros associated with the compensator.

D 15N-edited NOESY (15N-NOESY-HMQC) provides imino-imino, imino-amino and aromatic-imino/amino connectivities. The approach often fails in regions such as loops and bulges where bases do not form hydrogen-bonded pairs. In that case, imino assignment can be obtained from...

A landmark paper by Bums and colleagues (115) first described RNA editing events in rat brain. RNA editing involved an adenosine to inosine substitution, required the action of two separable double-stranded RNA (dsRNA) and adensosine deanimase(s) (ADARs), and occurred at four sites (A, B, C, and D) located within the second intracellular loop of the receptor. RNA editing in the r5-HT2C receptor resulted in seven major isoforms (VNV, VSV, VNI, VSI, INV, ISV, and INI) encoded by 11 RNA species (115). Also, patterns of RNA editing were tissue-specific the most common variants (VNV, VSV, VNI, and VSI) were expressed in the whole brain and hippocampus, whereas the least common variants (INV, ISV, and INI) were expressed in the choroid plexus. Functionally,... 

In contrast, GRK and arrestin both modulate the internalization of 5-HT2c receptors. Posttranscriptional RNA modification involving adenosine-to-inosine editing in the second intracellular loop generates 14 different isoforms of the...

Experiment with the program for a while, trying out different parameters. For example, try producing the same sound with a smaller loop rate. Press fl to enter edit mode, then press RETURN after the first seven prompts. Now enter 0.75 for the loop rate. Pressing RETURN at a prompt preserves the old value, so you need to type in only the parameters you want to change (however, you must always enter the loop rate for a falling tone). 

Figure 10 Portions of NOESY spectra and 1D slices through the frequencies of aromatic protons, (a) A 150-ms 2D NOESY spectrum of a 27-nt DNA stem-loop 93 a slice through the frequency of A5H8 is shown, (b) A 200-ms 2D NOESY spectrum of a 34-nt RNA stem-loop 68 a slice through the frequency of C7H6 is shown. Assignments of H5 and H5" protons are tentative. Note that some of the cross-peaks partially overlap with cross-peaks in another slice through the frequency of A8H2. (c) A 150-ms 3D 13C-edited NOESY-HMQC spectrum of the same molecule shown in (b). A slice of the proton and carbon frequencies of H6 and C6 in residue C7 are shown. Note a significantly lower digital resolution in the indirect uj2 dimension in this spectrum compared to the indirect u1 dimension in the 2D NOESY spectrum shown in (b).
