Free Radical Research, 1998
Peroxidation of lipids in membranes and lipoproteins proceeds through the classical free radical sequence encompassing initiation, propagation, and termination phases which are expressed by a lag phase in which little oxidation occurs, followed by a rapid increase in autocatalysis by chain-propagating intermediates and, finally, a decrease in the rate ...

A study of plane wave propagation in anisotropic three-phase-lag and two-phase-lag model
International Communications in Heat and Mass Transfer, 2011Abstract The present paper deals with the study of plane wave propagation in anisotropic medium in the context of the theory of three-phase-lag model and two-phase-lag model. It is found that there exist one quasi-longitudinal wave (QL) and two transverse waves (QSH, QSV) and one quasi-longitudinal thermal wave (QLT).

Predictive modelling of the microbial lag phase: a review
International Journal of Food Microbiology, 2004This paper summarises recent trends in predictive modelling of microbial lag phenomena. The lag phase is approached from both a qualitative and a quantitative point of view. First, a definition of lag and an analysis of the prevailing measuring techniques for the determination of lag time is presented.

Modeling the lag phase of Listeria monocytogenes
International Journal of Food Microbiology, 2002An estimate of the lag phase duration is an important component for predicting the growth of a bacterium and for creating process models and risk assessments. Most current research and data for predictive modeling programs initiated growth studies with cells grown to the stationary phase in a favorable pH, nutrient and temperature environment.

A Fractional-Order Alternative for Phase-Lagging Equation
International Journal of Numerical Analysis and Modeling, 2023Summary: Phase-lagging equation (PLE) is an equation describing micro/nano scale heat conduction, where the lagging response must be included, particularly under low temperature or high heat-flux conditions. However, finding the analytical or numerical solutions of the PLE is tedious in general.

Quarterly Journal of the Royal Meteorological Society, 1979
AbstractThe conventional formulation of the wave‐CISK mechanism involves a quasi‐equilibrium assumption whereby the instantaneous large‐scale diabatic heating that is induced by cloud‐scale motions is assumed to be related to the instantaneous distribution of the large‐scale flow, and in particular to the low‐level moisture convergence of the large ...

Stochastic modelling of bacterial lag phase
International Journal of Food Microbiology, 2002In order to study the lag distribution of the individual cells in a bacterial population, a stochastic birth model is used in this study. An integral formula is applied to transform the assumed lag distribution into a growth function describing the transition between lag and exponential phase of the cell population.

Comparison of definitions of the lag phase and the exponential phase in bacterial growth
Journal of Applied Bacteriology, 1992M.H. ZWIETERING, F.M. ROMBOUTS AND K. VAN 'T RIET. 1992. Different definitions of the lag time and of the duration of the exponential phase can be used to calculate these quantities from growth models. The conventional definitions were compared with newly proposed definitions. It appeared to be possible to derive values for the lag

Mathematical modeling of lag phases in microbial growth
Biotechnology and Bioengineering, 1978AbstractThis paper describes a mathematical model of the lag phases of Saccharomyces cerevisiae that incorporates the basic concepts previously presented in a two‐stage deterministic model for the growth of this organism under conditions of oxygen excess with a sugar as the growth‐limiting substrate.
