Growth kinetics of Candidatus 'Methanoperedens nitroreducens' enriched in a laboratory reactor.
Science of the Total Environment, 2019Recently it has been shown that Candidatus 'Methanoperedens nitroreducens', an anaerobic methanotrophic archaea (ANME), can reduce nitrate to nitrite using electrons derived from anaerobic oxidation of methane.

Grain growth kinetics of Er2O3 doped ZnO-V2O5 based varistor ceramics
, 2019Control of grain coarsening during sintering of oxide mixtures remains a challenge to manufacture high-performance varistors. This article reports microstructural evolution, grain growth kinetics and nonlinear electrical properties of Er2O3 (0–1.0 mol ...

Kinetics of Compensatory Growth
The Quarterly Review of Biology, 1965Growth in tissues and organs can be stimulated by either partial ablation or increased demands for physiological activity. Both causes appear to operate via identical pathways whereby the mounting requirements for extra functional output stimulate DNA replication and concomitantly promote specific protein synthesis.

Kinetics of Haemopoietic Colony Growth
British Journal of Haematology, 1971Summary. On continuous whole‐body γ irradiation at a dose rate of 70 rad/day the colony forming haemopoietic stem cells (CFU) show a biphasic dose–response curve where the first steeper phase is indistinguishable from the acute dose–response curve, indicating a lack of dose‐rate effect.

Kinetics of deterrence of gompertzian growth
Bulletin of Mathematical Biology, 1983Kinetic equations for the action of a reagent on a population which is increasing by Gompertzian growth are solved by a combination of analytical and numerical methods for both dilute distributions and cellular aggregates. For the aggregates an empirical function controlling extent of diffusion is used with external reagent concentration held constant,

Field theory for growth kinetics
Physical Review B, 1988We present a new field-theory method for growth-kinetics problems which describes the entire time evolution of the system from the early stage after the quench until final equilibrium is attained. The method is developed for a scalar order parameter (conserved or nonconserved) with dynamics of the Langevin type and a systematic low-temperature ...

Rational Kinetics Control toward Universal Growth of 2D Vertically Stacked Heterostructures
Advances in Materials, 2019The rational control of the nucleation and growth kinetics to enable the growth of 2D vertical heterostructure remains a great challenge. Here, an in‐depth study is provided toward understanding the growth mechanism of transition metal dichalcogenides ...

Journal of Experimental Biology, 1929
ABSTRACT The relationship between the increase in size of a growing organism and the period of time occupied in the process largely depends upon the nature of the environment in which the growing cells are placed. If a bacterium or a fibroblast is isolated in a suitable culture medium, the cell will divide and grow at a constant rate as ...

Growth kinetics of platelet thrombi
Journal of Theoretical Biology, 1977Abstract A model for the kinetics of a platelet thrombus growth is presented, which takes into account the principal hydrodynamic and cellular adhesion features of thrombus development. These consist of the rate at which platelets encounter the growing thrombus, their residence time near the surface of the thrombus, the rate of escape over the ...
