Effect of non-fiber carbohydrates on in vitro first order kinetics disappearance of cellulose
An in vitro experiment was conducted to determine the effect of supplemental non-fiber carbohydrate(NFC) on the disappearance kinetics of cellulose (Ce) by mixed ruminal microorganisms. Non-supplementedor NFC supplemented cellulose (467 mg NFC/g cellulose as sucrose (CeSu) or starch (CeSt) or a 1:1 mixtureof sucrose + starch (CeSuSt)) were incubated for 24, 48, and 96 h at 39°C. After each incu...
متن کاملSoybean Oil Transesterification Reactions in the Presence of Mussel Shell: Pseudo-First Order Kinetics
Calcium oxide is one of the appropriate catalysts for biodiesel production. In this study, cheap and compatible with environment catalyst has been used. Mussel shell of Persian Gulf coast is one of the sources of calcium carbonate that is converted to calcium oxide at calcination temperature up to 950°C. Transesterification reaction was carried out at optimum condition of our previous study...
متن کاملSimulation of First-Order Chemical Kinetics Using Cellular Automata
Cellular automata are dynamical systems composed of arrays of cells that change their states in a discrete manner following local, but globally applied, rules. It is shown that a two-dimensional asynchronous cellular automaton simulates both the deterministic and the stochastic features of first-order chemical kinetic processes in an especially simple manner, avoiding the chore of solving eithe...
متن کاملClusters, Metastability, and Nucleation: Kinetics of First-Order Phase Transitions
We describe and interpret computer simulations of the time evolution of a binary alloy on a cubic lattice, with nearest neighbor interactions favoring like pairs of atoms. Initially the atoms are arranged at random; the time evolution proceeds by random interchanges of nearest neighbor pairs, using probabilities compatible with the equilibrium Gibbs distribution at temperature T. For temperatur...
متن کاملComplexity-reduction by first-order approximation of non-linear kinetics
Ecological, toxicological, and pharmacological research is often concerned with the answer to the question of how a substance is processed within a biological system. The exact knowledge of the corresponding kinetic pattern forms the basis for a useful answer. In order to identify non-linear kinetics, a firstorder approximation method is proposed for complexity-reduction. A simulation study is ...
