Mutual Exclusion (MUTEX). The idea of multiple entities all working on the same piece of work raises this issue of coordination and communication among the individual processes. A weU-known example from banking is instmctive. Consider two bank tellers simultaneously performing withdrawals from the same bank account. Both read the account balance and determine that the balance is 100, and so a withdrawal of 100 is allowed. Both then withdraw 100 from the account. Clearly this process needs some means by which the actions of the independent processes can be synchronized and coordinated. 

Slip frequency is the difference between synchronous speed and actual running speed of the motor. A narrowband filter should be established to monitor electrical line frequency. The window should have enough resolution to clearly identify the frequency and the modulations, or sidebands, that represent slip frequency. Normally, these modulations are spaced at the difference between synchronous and actual speed, and the number of sidebands is equal to the number of poles in the motor. 

Clear evidence in favor of 6.75 being an intermediate came, however, from stereochemistry. If the indazole cyclization takes place at a chiral carbon atom in the exposition of the alkyl group in 6.78, the stereochemistry of the 3-i/-indazole 6.79 can indicate whether the 5-diazo-6-methylene-l,3-cyclohexadiene 6.75 is an intermediate or whether, on the other hand, deprotonation and cyclization are synchronous. In the first case a racemic indazole 6.79 is expected. In the case of a synchronous reaction, however, a stereospecific product, probably with retention of the chirality at Ca, should be observed. 

The multiple sites that serve as origins for DNA replication in eukaryotes are poorly defined except in a few animal viruses and in yeast. However, it is clear that initiation is regulated both spatially and temporaUy, since clusters of adjacent sites initiate rephcation synchronously. There are suggestions that functional domains of chromatin replicate as intact units, implying that the origins of rephcation are specificaUy located with respect to transcription units. 

The small solvent isotope effect shows clearly that a proton transfer is not part of the rate-determining step of the hydrolysis. Christensen (1966, 1967) favors an SN2-type mechanism (164) for the hydrolysis, with nucleophilic attack of water on a sulfonyl group synchronous with the departure of ArSO. The alternative formulation (165), however, where a pentacovalent inter-... 

By the early 1960s it was clear that simple experiments on P uptake were inadequate to distinguish different species of RNA in mixed populations of cells at different stages of the cell cycle. The future for labeling experiments with 32P in cell biology was to lie mainly with synchronized cells and for studies on nucleic acids, with molecular biological techniques. 

In effect, synchronized commerce allows UPS to sell more products and services to its existing customers. To effectuate this model, UPS acquired nearly thirty service providers with expertise in different areas of synchronized commerce freight forwarders, customer clear-ers, a bank for export financing, fulfillment services, customer returns and repairs. Eskew defined synchronized commerce as the coordinated... 

The effect of the volume and the surface catalytic reaction is sketched in Figs. 2.80 and 2.81, respectively. Obviously, the voltammetric behavior of the mechanism (2.188) is substantially different compared to the simple catalytic reaction described in Sect. 2.4.4. In the current mechanism, the effect of the volume catalytic reaction is remarkably different to the surface catalytic reaction, revealing that SWV can discriminate between the volume and the surface follow-up chemical reactions. The extremely high maxima shown in Fig. 2.81 correspond to the exhaustive reuse of the electroactive material adsorbed on the electrode surface, as a consequence of the synchronization of the surface catalytic reaction rate, adsorption equilibria, mass transfer rate of the electroactive species, and duration of the SW potential pulses. These results clearly reveal how powerful square-wave voltammetry is for analytical purposes when a moderate adsorption is combined with a catalytic regeneration of the electroactive material. This is also illustrated by a comparative analysis of the mechanism (2.188) with the simple surface catalytic reaction (Sect. 2.5.3) and the simple catalytic reaction of a dissolved redox couple (Sect. 2.4.4), given in Fig. 2.82. 

H MAS NMR clearly shows five signals at 0.8, 1.9, 4.4, 10.1 and 12.1 ppm. The signals at 0.8, 1.9 and 4.4 are assigned to alkyl fragments bonded to silicon atoms, residual silanol groups on the silica surface and to silicon hydride species, respectively. The two downfield signals at 10.1 and 12.1 ppm are an indication of the presence of two types of zirconium hydride surface species [111]. DQ rotor-synchronized 2D H MAS NMR was used to discriminate these zirconium hydride... 

Although the precise mechanism of action of paclitaxel in enhancing radiation effects is not clear, one of the proposed mechanisms is its effect on the cell cycle. Its effects on the microtubules result in an M-phase arrest (55). Experiments done on synchronously dividing Chinese hamster cells have shown that cells in M and G2 are most sensitive to the effects of radiation (56). 

The direct interpretation of the signals from several detectors in SEC experiments has been analysed. It is clear that the direct interpretation of the synchronized signals from detectors having...
