expanded graphite nanosheets (eg-nanosheets) were used for adsorption of malachite green (mg) from aqueous solution. the influences of dye concentrations, absorbent dosage, ph values and the temperatures on the adsorption were investigated as well. the dye adsorption experiments were carried out by utilizing batch procedure. eg-nanosheets were initially characterized by scanning electron micros...

mathematical modeling and simulation of microbial polyhydroxybutyrate (phb) production process is beneficial for optimization, design, and control purposes. in this study a batch model developed by mulchandani et al., [1] was used to simulate the process in matlab environment. it was revealed that the kinetic model parameters were estimated off the optimal or at a local optimal point. therefore...

in this work, mathematical modeling of microbial(trichosporon sp.) biomass production in a stirred tankbioreactor and in an external airlift bioreactor has beeninvestigated. a model based on a tanks-in-seriesmodel without back-flow has been used to simulate theproduction of single cell protein in the external airliftbioreactor under an unsteady condition and withoutoxygen limitation, utilizing ...

We describe a workflow to translate a given metabolic network into a kinetic model; the model summarises kinetic information collected from different data sources. All reactions are modelled by convenience kinetics; where detailed kinetic laws are known, they can also be incorporated. Confidence intervals and correlations of the resulting model parameters are obtained from Bayesian parameter es...

For the development of mathematical models in chemical engineering, the parameter estimation methods are very important as design, optimization and advanced control of chemical processes depend on values of model parameters obtained from experimental data. Nonlinearity in models makes the estimation of parameter more difficult and more challenging. This paper presents an evolutionary computatio...

NABAVI, SEYEDBEHZAD. Kinetic Parameter Estimation in Oscillatory Biochemical Systems. (Under the direction of Cranos M. Williams.) Oscillatory pathways are among the most important classes of biochemical systems with examples such as circadian rhythms and cell cycles. Mathematical modeling of these highly interconnected biochemical networks is needed to meet numerous objectives such as investig...
