Osmani, A. H., McGuire, S. L., and Osmani, S. A. (1991). Parallel activation of the NIMA and p34cdc2 cell cycle-regulated protein kinases is required to initiate mitosis in A. nidulans. EMBO J. 67 283-291. 

What is the shortest time in which this task could be done First, since there are at most five parallel activities (N, L, P, R, and Q can occur at the same time), a maximum of five people can be employed at any one time. Second, let us consider the path that gives us the longest time necessary to reach each node. This will be the minimum time that must elapse before the activity that follows can begin. For instance, before activity H can begin, 180 seconds must elapse. Each item on the path, C, D, and E, must be completed before H can begin, and these activities must be done in sequence. 

Certainly a wise solution to contrast such a flood of absurdities is to invest in multidisciplinary research and intense demonstration, and parallel activities of capacity building with the active participation of the stakeholders. When convinced producers become the sentinels of environmental quality obvious and durable advantages on the ground of social and environmental impacts will be achieved. 

Structure packages to consistently separate interfaces from implementations, and aim for early initial definition of interfaces. Also, designate team roles that cut across parallel activities, watching for issues or overlaps that should be addressed separately. 

Regulation of the Pycomplex is another interesting aspect of the function of adenylyl cyclase. The inhibitory Pv-complexes probably do not come from the Gs-proteins from which activation of adenylyl cyclase originates. Rather, it is speculated that the inhibitory Pycomplex is released as a consequence of a parallel activation of Gi and Go-proteins, which both exist at much higher concentrations than the Gs-proteins. 

Reactions which formally can be classified as cycloadditions or retrocycloadditions have been observed in homogeneous solution with single electron oxidative initiation, so the observation of parallel activity on irradiated semiconductor suspensions is certainly reasonable. The first example of such a reaction involved the photocatalysis by ZnO or CdS of the ring-opening of a strained hydrocarbon which could also be opened in the dark by a single electron oxidant, ceric ammonium nitrate, Eq. (38)... 

In parallel, activity of adenylate cyclase is inhibited by Ca2+, and the ion activates the membrane-embedded CAM to close the cAMP-dependent channels. In addition, CAM-PDE is induced to hydrolyze the messenger molecules rapidly. 4) Finally, Ca2+ activates the cytoplasmic CAM to enhance the activity of Ca2+-translocating ATPase, causing the cells to return to the resting state.

Under similar conditions, even benzylic C-H bonds of some hydrocarbons (xanthene and fluorene) are converted to the ketones (e.g., fluoren-9-one). Notwithstanding the parallel activities of the two catalysts, different mechanisms were tentatively proposed (277-279). Thus, for R.UC0AI-LDH-CO3, it was postulated that the presence of Co in the structure facilitated the formation of high-valent Ru(V)=0 species. In contrast, for the Ru-HAP catalyst, it was proposed that after coordination of the reactant to Ru as an alcoholate, the carbonyl compound was eliminated, leaving a Ru-H compound, which in a next step is reoxidized by O2. The basic nature of the HAP (or LDH) support may actually favor the latter route, with formation of an alcoholate. Filtration tests and elemental analyses confirm the stability of the supported species in both catalysts. 

The critical path for a project is that which determines the shortest time in which a project can be completed. It is of greatest value where there are sophisticated network diagrams, involving multiple parallel activities. 

ReMe(NAr)20 reacts rapidly with P(OMe)3 to form OP(OMe)3 and ReMe(NAr)2 P(OMe)3 2 (73). More basic phosphines react very slowly but replace P(OMe)3 in (73). Interestingly, (73) under O2 rapidly forms ReMe(NAr)20 and 0P(0R)3. This catalytic reaction is proposed to take place via the peroxo complex (74) that unveils the activation of molecular O2 by a ReMe(NAr)2 fragment. A parallel activation of O2 with MTO is, however, less efficient. ... 

Temperature is likely the most important variable affecting the catalytic cracking of plastics. Reaction temperatures are usually in the range 300-450°C. In general, a temperature increase leads towards a parallel activity enhancement of the catalysts. Nevertheless, it must be taken into account that at high temperatures the simultaneous occurrence of thermal cracking reactions is favoured, which may modify the product selectivity. 

The cardiac action potential can be divided into five phases, numbered 0-4. These phases result from the subsequent or parallel activity of ion channels (Figure 3.2) and/or transporters. Initially, the cell is polarized to near the electrochemical potential for potassium ions because of high K+ conductance at rest. A rapid depolarization is initiated by the activation of the fast inward Na+ current (phase 0). This depolarization is followed by a brief partial repolarization mainly resulting from the activation of the transient outward current (/t0) and the inactivation... 

The results of animal tests of the types described above with delta-1-THC, delta-6-THC, and other cannabinoids have been shown to parallel activity in man (Hollister 1974). Hence, we assume that the results with (32) and (33) likewise indicate parallel activity in man. If this correct, cannabimimetic activity in man has a strict stereochemical requirement, which indicates a probable interaction with a chiral biological system (enzyme, receptor site, etc.) and not just an unspecific action due to the high lipid solubility of the cannabinoids.

Although fewer dlthiocarbamates were Investigated, results from those studied suggest that structure-activity correlations derived for thiolcarbamates were only partly applicable to dlthiocarbamates. Differences between thiolcarbamates and dlthiocarbamates were clearly highlighted from the lack of parallel activity between three analog pairs 24 and 35, 26 and 32, 29 and...
