Kinetics of interaction between polyreactive immunoglobulins and antigen. The theory [PDF]

open access: yesThe Ukrainian Biochemical Journal, 2019
Dynamics of association between polyreactive immunoglobulins (PRIGs) and immobilized antigens is considered on the base of our model of PRIGs-antigen interaction, which was suggested by us earlier.

Theoretical Study of an Undisclosed Reaction Class: Direct H-Atom Abstraction from Allylic Radicals by Molecular Oxygen

open access: yesEnergies, 2021
The 1-methylallyl (C4H71-3) allylic radical is an important intermediate species in oxidation of linear C4 unsaturated hydrocarbons (1-butene, 2-butene, and 1,3-butadiene).

Analysis of initial chlorophyll fluorescence induction kinetics in chloroplasts in terms of rate constants of donor side quenching release and electron trapping in photosystem II [PDF]

open access: yes, 2008
The fluorescence induction F(t) of dark-adapted chloroplasts has been studied in multi-turnover 1 s light flashes (MTFs). A theoretical expression for the initial fluorescence rise is derived from a set of rate equations that describes the sequence of ...

Are rate constants constant?

open access: yesThe Journal of Physiology, 2006
In this issue of The Journal of Physiology, Uebachs et al. (2006) report a seemingly simple observation: the rate of recovery from inactivation of CaV3 (T-type) calcium channels depends on the length of the depolarization that produced the inactivation. Why is this heretical? A basic principle of chemical kinetics is that rate constants are constant.

Analysis of DCE-MRI Data using a Nonnegative Elastic Net [PDF]

open access: yes, 2010
We present a nonnegative Elastic Net approach for the analysis of Dynamic Contrast-Enhanced Magnetic Resonance Imaging data. A multi-compartment approach is considered, which is translated into a (restricted) least square model selection problem.

Reactions of C+ + Cl-, Br-, and I--A comparison of theory and experiment. [PDF]

open access: yes, 2019
Rate constants for the reactions of C+ + Cl-, Br-, and I- were measured at 300 K using the variable electron and neutral density electron attachment mass spectrometry technique in a flowing afterglow Langmuir probe apparatus. Upper bounds of <10-8 cm3

On the kinetics of the hydrogen evolution reaction on zinc in sulfate solutions [PDF]

open access: yesJournal of the Serbian Chemical Society, 2001
The kinetics and mechanism of the hydrogen evolution reaction (her) were studied on zinc in 1.0 mol dm-3 Na2SO4 at 298 K, in the pH range 4.4 – 10.

On the Influence of Uncertainties in Chemical Reaction Rates on Results of the Astrochemical Modelling

open access: yes, 2003
With the chemical reaction rate database UMIST95 (Millar et al. 1997) we analyze how uncertainties in rate constants of gas-phase chemical reactions influence the modelling of molecular abundances in the interstellar medium.
