Abstract: Main parameters of the 1-5 diphenylcarbazide standard method for specrophotometrical detection of Cr(VI) metal ions in water were optimized for application on a miniaturized and portable device for continuous monitoring of water pollution. The aim was the reduction of involved volumes, manageable by a microfluidic device, the choice of suitable solvents and acid solutions, the optimization of reagents amounts and the radiation of the sample by a single wavelength visible source. The optimized process was verified on a bench prototype.

Abstract: Modeling the regulation of lactose operon expression is significant to understand lactose metabolism at the cell-level, in which the repressor and cAMP-CRP can influence its regulation process. In this paper, a mathematic model of lactose operon expression is established in differential equations with the knowledge of system biology. Considering multiple factors such as lactose, glucose, repressor, permease, β-galactosidase, allolactose and cAMP-CRP, this paper presents dynamic bi-direction regulatory mechanisms in both repressor and cAMP-CRP with the logical “AND†of system biology. The experimental data indicates that the proposed model is more approach to the real condition.
