Combustion and Flame, 2008 A criterion based on computational singular perturbation (CSP) is proposed to effectively distinguish the quasi steady state (QSS) species from the fast species induced by reactions in partial equilibrium. Together with the method of directed relation graph (DRG), it was applied to the reduction of GRI-Mech 3.0 for methane oxidation, leading to the ...

Chemistry and Transport of Potassium during the Non‐Steady State of Syenite Leaching
Soil Science Society of America Journal, 2017 Core Ideas A flow system for the release and extraction kinetics of ions from a rock fertilizer. The initial release of ions from syenite studied using ICP‐MS and a pH meter. Fast surface potassium–proton ion exchange and K desorption observed. Syenite is mainly composed of potassium feldspar (Kfs), which is a structural K‐bearing mineral in soil ...

An efficient Chebyshev wavelet based analytical algorithm to steady state reaction–diffusion models arising in mathematical chemistry [PDF]
Journal of Mathematical Chemistry, 2015 A mathematical model of amperometric biosensors has been developed. The model is based on non-stationary diffusion equation containing a nonlinear term related to non-Michaelis–Menten kinetics of the reaction. In this paper, an efficient Chebyshev wavelet based approximation method is introduced for solving the steady state reaction–diffusion equations.

Thin Solid Films, 1999 Abstract Polarization-modulated Fourier-transform infrared reflection absorption spectroscopy has been applied to the characterization of thin films of AlN and Al oxynitride (‘AlON’) on NiAl(111) and to the observation of surface chemical processes under steady-state conditions in a static NH 3 ambient of up to 200 Torr.

The Journal of Membrane Biology, 2014 The mathematical model of Rahamathunissa and Rajendran (J Math Chem 44:849-861, 2008) in an amperometric biosensor response is discussed. In this paper, we have applied the shifted second kind Chebyshev wavelets (CW) to obtain the numerical solutions of reaction-diffusion equations containing a nonlinear term related to Michaelis-Menton kinetics of the

Free Radical Biology and Medicine, 2001 Apoptosis was studied under conditions that mimic the steady state of H(2)O(2) in vivo. This is at variance with previous studies involving a bolus addition of H(2)O(2), a procedure that disrupts the cellular homeostasis. The results allowed us to define three phases for H(2)O(2)-induced apoptosis in Jurkat T-cells with reference to cytosolic steady ...

Canadian Journal of Fisheries and Aquatic Sciences, 2002 Critical loads of acidity and the amount by which these critical loads are exceeded by atmospheric deposition (termed "exceedances") were estimated for 1469 lakes from five regions in south-central Ontario, Canada, using single lake chemistry measurements and sulphur deposition data for the period 19761999.

Science of The Total Environment, 2008 Criteria are needed for distinguishing naturally acid water from that acidified by air pollution, especially in the organic-rich waters of northern Sweden. The Steady-State Water Chemistry Model (SSWC) was augmented to include organic acidity so that it could predict pre-industrial pH in organic-rich waters.

Journal of Chemical Education, 2014 A numerical analysis of the free radical addition polymerization system is described that provides those teaching polymer, physical, or advanced organic chemistry courses the opportunity to introduce students to numerical methods in the context of a simple but mathematically stiff chemical kinetic system.
