Equal reaction rates for all recombination pathways

چکیده
Formal collision theory indicates that the absolute termolecular recombination reaction rate can be expressed in a form associated either with direct or indirect mechanisms for the recombination. Moreover, the same exact rate constant can be calculated using either of the four mechanisms. These results are to be contrasted to the rate constants standardly calculated by approximate methods. © 1997 American Institute of Physics. @S0021-9606~97!01104-5#

The ortho : para ratio of H3+ in laboratory and astrophysical plasmas.
In diffuse molecular clouds, the nuclear spin temperature of H(3)(+) (approx. 30 K) is much lower than the cloud kinetic temperature (approx. 70 K). To understand this temperature discrepancy, we have measured the ratio of the hop to exchange pathways (α) in the H(3)(+) + H(2) --> H(2) + H(3)(+) reaction (which interconverts ortho- and para-H(3)(+)) using high-resolution spectroscopy of the ν(2...
متن کاملBioreactor Scale-up for Water-Gas Shift Reaction
A scale-up study has been performed with three different size reactors to establish the optimum operating conditions for the hydrogen production from synthesis gas by biological water-gas shift reaction using the photosynthetic bacterium Rhodosprilliunt rubrum. Optimum medium composition and operating conditions previously determined in a bench scale 1.25 L continuous stirred tank reactor (CSTR...
متن کاملRecombination dynamics in bacterial photosynthetic reaction centers.
The time dependence of magnetic field effects on light absorption by triplet-state and radical ions in quinone-depleted reaction centers of Rhodopseudomonas sphaeroides strain R-26 has been investigated. Measurements on the time scale of the hyperfine interaction in the radical pair [(BChl)2+. ...BPh-.)] provided kinetic data characterizing the recombination process. The results have been inter...
متن کاملInteraction of selection and recombination in the fixation of negative-epistatic genes.
We investigated the interaction of recombination and selection on the process of fixation of two linked loci with epistatic interactions in fitness. We consider both the probability of fixation of newly arising mutants (the static model) and the time to fixation under continued mutation (the dynamic model). Our results show that the fixation of a new advantageous combination is facilitated by h...
متن کاملExtrachromosomal recombination occurs efficiently in cells defective in various DNA repair systems.
A series of different frameshift mutations of a firefly luciferase reporter plasmid was created so that no activity was obtained when they were transfected into mammalian cells. Co-transfection of these constructs with short fragments of the original sequence resulted in luciferase activity in different cell lines (A-549, NIH 3T3 and Jurkat). The level of this activity was dependent on the leng...
