Sentence examples for onset of evolution from inspiring English sources

However, it does seem that there was a major alteration of cell division mechanisms at the onset of evolution of the PVC superphylum, with subsequent elaborations in individual lineages [ 48], and experimental study of division in these bacteria will be of major interest.

Although it has been claimed that ligase III was unique to vertebrates [ 14], our analysis detected clear orthologs in insects, the choanoflaggelate Monosiga brevicola and the social amoeba Dictyostelium discoideum, suggesting that ligase III evolved through a duplication of the ligase IV gene at the onset of evolution of unikonts but was repeatedly lost in fungi and several animal lineages.

In the absence of such candidates, it is generally assumed that tubulin evolved from FtsZ at the onset of eukaryote evolution, and this evolution engendered extreme sequence divergence associated with the shift in function [ 14].

This and the absence of AANATs from the genomes of Hemichordates and Urochordates support the view that a major transition in the evolution of the AANATs may have occurred at the onset of vertebrate evolution.

Germanium can be deposited only after the onset of hydrogen evolution in any acidic and alkaline solutions with very low yield.

Borate was adsorbed onto the electrode surface and shifted the onset of hydrogen evolution towards more cathodic potentials as borate concentration was increased.

In Fig. 1a and b, it can be seen that the onset of hydrogen evolution reaction (HER) is earlier at pH 1.46 for both P4VP modified and unmodified copper deposited GDL.

Specifically, the voltammetry of Pt(1 1 1) and Pt(1 0 0) in dopamine solutions shows an oxidation peak at potentials close to the onset of hydrogen evolution, which is related to the desorption of hydrogen and the adsorption of dopamine.

For chronoamperometry performed at the onset of oxygen evolution, the electrode remained active even at low temperatures because the discharge of water involved the production of hydroxyl radicals that destructively oxidized the polymeric film.

Although the cyclic voltammograms of ruthenium in alkaline solutions are broad and relatively featureless, PMRS allows identification of soluble RuO42− (Ru VI)) and RuO4− (Ru VII)) species formed at the onset of oxygen evolution.

We have studied the electrocatalytic hydrogenation of acetophenone and benzophenone using a) potentiometric titration of adsorbed hydrogen by the organic reactant in excess, b) electrochemical impedance spectroscopy at a potential at the onset of hydrogen evolution and c) electrolysis at constant potential at high adsorbed hydrogen coverage.
