Surface Microfouling During the Induction Period
Journal of Heat Transfer, 1983The time during which newly installed or cleaned heat transfer surfaces remain free of fouling deposits thick enough to diminish heat transfer coefficients or energy efficiency is often called the “induction period,” a term disguising lack of knowledge of the microfouling events actually occurring.

The Induction Period in Development
The Journal of Photographic Science, 1975AbstractSince Ihe exposure-dependent induction periods controlling the developmenl of individual grains in an emulsion and induction periods derived from the overall kinetics of development depend upon different experimental faclors and arc not necessarily connected, they should be called different names.

Theory of long induction periods
Journal of Crystal Growth, 1987Abstract Current theories relating induction periods in crystallization to either stationary nucleation rate or relaxation time of embryo distribution are of limited validity. The Zeldovich-Frenkel theory overestimates the growth rate of postcritical embryos with high surface energy.

DSC Study of Oxidation Induction Periods
Journal of Thermal Analysis and Calorimetry, 2001A theory of the evaluation of kinetic parameters of induction periods for non-isothermal processes is outlined and a method to obtain the parameters from non-isothermal differential scanning calorimetry measurements, based on the dependence of onset temperature of oxidation peak on heating rate, is presented.

Measuring induction period for calcium sulfate dihydrate precipitation
AIChE Journal, 1999AbstractHomogeneous nucleation of CaSO4·2H2O (gypsum) based on an optical diagnostic technique was studied within a supersaturation range of 1–4 at 25–90°C. The experiments were carried out using an experimental apparatus consisting of a batch crystallizer with the related measurement devices. Signals of scattered and transmitted light coming from a He–

Latent period in the induction of reticuloendothelial blockade
American Journal of Physiology-Legacy Content, 1960Double intravenous injections of colloidal carbon in the mouse, with variation of the time between doses and with blood disappearance curves taken after the second dose, revealed a delay of over 3 hours in onset of reticuloendothelial blockade due to the first carbon dose.

Explosions with Chain Branching: Induction Period Analysis
Combustion Science and Technology, 1982Abstract A spatially homogeneous explosion with chain branching is studied using the method of activation energy asymptotics. The model consists of a chain branching reaction which is followed by a chain termination reaction. Both these reactions are considered exothermic, in general, with the former having a large and the latter an O(l) amount of ...

Induction motor response to periodical voltage fluctuations
The XIX International Conference on Electrical Machines - ICEM 2010, 2010The main aim of this paper is to analyze the behavior of the three-phase squirrel cage induction motor under different voltage fluctuation levels. To achieve this goal several simulations were performed using the EMTP/ATP tool. Here we present how mechanical torque, speed and efficiency parameters varied with different levels of voltage fluctuation and

Induction period in the aging of polypropylene
Journal of Applied Polymer Science, 1965AbstractThe ordinary methods for obtaining a rapid estimate of the useful life of a plastic, extrapolations from tests conducted at higher temperatures or at lower stabilizer concentrations than those of actual use, lead to serious errors in estimating the useful life of some stabilized polypropylene compositions.
