Uranium Bio-Transformations: Chemical or Biological Processes?

Dynamic model-based fault diagnosis for (bio)chemical batch processes

To ensure a constant and satisfactory product quality, close monitoring of batch processes is an absolute requirement in the chemical and biochemical industry. Principal Component Analysis (PCA)-based techniques exploit historical databases for fault detection and diagnosis of the current batch run. To handle the dynamic nature of batch processes, dedicated techniques such as Batch Dynamic PCA ...

Electrical Model for Analyzing Chemical Kinetics, Lasing and Bio-Chemical Processes

In this paper we present the analogous electrical model for analyzing and determining the precise time dependence of concentrations in general first and zero order chemical reactions. In addition, the applicability of this analogous electrical model for investigating the optical and bio chemical processes is also presented. By constructing the proper analogous electrical circuit experimentally ...

Chemical and Biological Processes: the Need for Mixing

Except for spontaneous reactions such as radioactive decay, chemical transformations often require that two or more substances be brought together for the transformation to occur. Examples of particular interest in groundwater are oxidations of inorganic or organic species, which require the presence of some oxidant, such as diatomic oxygen (O2), nitrate, sulfate, or ferric iron (Fe(III)). In b...

Discrimination of dynamical system models for biological and chemical processes

In technical chemistry, systems biology and biotechnology, the construction of predictive models has become an essential step in process design and product optimization. Accurate modelling of the reactions requires detailed knowledge about the processes involved. However, when concerned with the development of new products and production techniques for example, this knowledge often is not avail...
