The high activity is due to the concurrent reactions of RWGSR and ammonia synthesis.
This would be expected as the production rate of Tyr drops due to less production from decreasing [Phe], combined with expected concurrent reactions of Phe and Tyr competing for the same available.
In contrast, OH attacks polysaccharides at multiple carbons and only some of these events actually cut the polysaccharide backbone; concurrent reactions introduce oxo groups into the polysaccharide ('collateral damage') without cleaving it [ 12, 28, 29].
The differences in reactivity might be expected to have a significant effect on the coreactant sequence lengths in prepolymers formed by the concurrent reaction of PA, IA and MPD particularly at low conversions thus on the final properties of the cured resins in which they are employed.
The catalytic oxidation of methanol to formaldehyde coupled to the gas phase oxidation of formaldehyde to carbon dioxide is used as an example of a consecutive reaction: the decomposition of nitrous oxide in the gas phase or over gold catalysts is used as an example of a concurrent reaction.
This tradeoff is considered here by calculating the stress fields resulting from concurrent insertion reaction and plastic flow for both spherical and cylindrical hollow core shell nanostructures.
The main reactions controlling major ion chemistry were found to be calcite equilibrium and concurrent Na Ca exchange reactions and de-protonation of functional surface groups.
Besides drug-related events, immunological reactions and concurrent infections can play a role in the clinical deterioration of patients on antituberculous treatment, particularly in the HIV-infected [10].
Although TB treatment is challenging in HIV-infected patients because of treatment interactions, immunopathological reactions, and concurrent infections, few prospective studies have addressed this in sub-Saharan Africa.
A paradoxical reaction was classified as probable when 1) an initial favorable response to antituberculous treatment was followed by 2) new onset or recrudescence of TB manifestations and 3) at least a minimum diagnostic work-up had been done to exclude potential alternative diagnosis such as poor adherence, drug reactions, and concurrent infection.
