In this paper we present a general derivation of kinetic models for traffic flows including different kind of interaction rules. We show that most kinetic models previously derived can be cast in the actual formulation. The development of Monte Carlo methods for direct simulation of the kinetic models is considered as an initial step towards realistic and efficient computations of traffic pheno...
Rapid developments in the relatively new disciplines of ‘bioinformatics’, ‘computational biology’ and ‘systems biology’ have led to a marked increase in the use of kinetic models in the study of complex biological systems [for example, see ‘Nature insight: Computational biology’ (2002) Nature 420, 205–251]. When reading publications in these ‘new’ fields, it is easy to overlook the fact that th...
Microbial transport in soil is critical in different ways, especially in groundwater contamination and bioremediation of groundwater or soil. The main objectives of this research were quantitative study of bacterial transport and deposition under saturated conditions in calcareous soils. A series of column leaching experiments were conducted. Breakthrough curves (BTCs) of Pseudomonas fluorescen...
The kinetics and isotherm studies of the immobilized lipase and the mechanism of immobilization on chitosan beads and activated chitosan beads with glutaraldehyde were investigated. The effect of glutaraldehyde on porosity of chitosan was evaluated by FESEM analysis. It was observed that the porosity of the carrier which has activated by glutaraldehyde was substantially increased. The validity ...
Background and Objectives: Increasing waste tiers production has made the recycling of this solid waste a critical issue in the world. On the other hand, it seems contamination of groundwater to the petroleum pollutant like gasoline is a great threat to the health of societies in developing countries. The main objective of this study was gasoline removal from aquatic environment by waste tire d...
An efficient design of in situ combustion depends on accurate kinetic modeling of the crude oil oxidation. The kinetic triplet of the oxidation reactions of a heavy oil sample was investigated. Once the kinetic triplet is known, the kinetic equation would be deconvolved. The crude oil sample was obtained from Kuh-E-Mond reservoir, located in the southwest of Iran. The samples were analyzed usin...
Macrospore created by decaying plant root provides pathways for rapid transport of pollutants in soil profile. The main objective of this study was quantitative analysis of the effect of plant root (Zea mays L.) on bacterial and chloride transport through soil. Experiments were conducted in 9 soil columns packed uniformly with loamy sand. The treatments were bare soil, bare soil with corn (Zea ...
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...
