A MOLECULAR AND KINETIC ANALYSIS OF ESTROGEN RECEPTOR TRANSFORMATION

Journal of Steroid Biochemistry, 1975
Abstract Recent studies of the uterine estrogen receptor indicate it is a multi-subunit protein. Estradiol and temperature induce a conformational change in the 4 S estrogen-binding protein (EBP) or monomer (mol. wt. 7–8 × 104) as indicated by the high energy of activation (19–21 kcal mol−1) accompanying the formation of the 4S EBP dimer, 5S EBP (mol.

Kinetics of Physical Transformations

1984
A concrete physical system may change in time. Any such change will be called a process, provided the change exists in every inertial coordinate system. In this broad sense, not only chemical reactions, positron—electron ‘annihilation’, nuclear reactions, etc., but also the emission and absorption of photons, and even a change in a purely mechanical ...

Kinetics of Phase Transformation—Initial Stage

2020
For a phase to transform, a daughter phase should first be conceived out of the mother phase, which is either via nucleation or via spinodal decomposition. Here, we will learn the classic basic ideas on the kinetics of these two conception processes: one is “small in extent and large in degree” involving downhill diffusion and the other “large in ...

Kinetics and hydrothermal transformation of gibbsite

Journal of Thermal Analysis, 1991
The transformation of gibbsite have been studied under hydrothermal influence. Results of the X-ray diffraction analysis of the samples heated at different temperatures from 170°C to 265°C are also discussed in detail. The percentage of the boehmite phase formed, due to the transformation of the gibbsite, have been determined by comparing the intensity

Analysis of the kinetics of phase transformations

Journal of Materials Science, 1992
A common basis of reaction-rate theories is discussed for isothermal and non-isothermal transformations. As a result compatible recipes have been obtained for the extraction of kinetic parameters from isothermally and non-isothermally conducted experiments. It follows that so-called Kissinger-like methods for non-isothermal kinetic analysis, originally

Kinetic equations and Lorentz transformation

Physica, 1968
Abstract It is known that, within the canonical formulation of statistical mechanics initiated by Dirac and developed by the author and Kotera, the Liouville equation is invariant under Lorentz transformations. As a direct consequence, it is shown that the general master equation, which is conceptually equivalent to the Liouville equation, is also ...

Kinetics of order-disorder transformations

Acta Metallurgica, 1955
Abstract A simple theory of the kinetics of order-disorder transformations, based on chemical rate theory, is presented. The theory is constructed entirely in terms of the long range order parameter and reduces to the Bragg and Williams theory at equilibrium. There are several unusual features in the theoretical rate curves.
