Some biopharmaceutical companies have responded to evolution of the competitive landscape by placing additional emphasis on reducing their costs of manufacturing as a means of maintaining competitiveness. The prototypical current generation biopharmaceutical drug substance manufacturing facility requires a large upfront capital investment. Improving efficiency of use of existing facilities, suc...

Taylor dispersion is a key concept in many fields. In the present paper, we characterize the pattern of the complete spatial concentration distribution for laminar tube flow; the obtained simple description is shown to represent the nature of Taylor dispersion. Importantly, we find that during the approach to the longitudinal normality of the transverse mean concentration at the time scale of R...

Indeed, the group of scaling transformations acts on the solution of the system considered. But these are particular solutions. For example, in [2], such solutions are considered in a quite different context. In [1], the assertion that a vacuum domain exists is derived from the assumption that such invariant solutions are unique. Such an assertion (in form, it pretends to be a description of so...

Process tomography is a sensing technique that can be used to measure distributed flows inside pipes. As a result, it is suitable for use as the sensor in a feedback control system for regulating the concentration of a substance in a fluid flow along the pipe. This paper describes such a control system and starts by developing a model based on the convection-diffusion equation, which describes ...

In our study, two-stage anaerobic system was employed to treat high concentration methanol wastewater. The results showed the COD removal efficiency was over 90% at the volume loading of 26.8kgCOD/(m.d) and two-stage anaerobic digestion of methanol wastewater was more efficient and stabler than one stage. The pH of the two UASBs was always lower than 6.0, which wasn’t the suitable condition tha...

Coffee is quite popular of the leisure drink, and the ingredients of coffee include caffeine, aroma, protein, tannic acid and fat et al. The references show a small amount of caffeine can stimulate the brain and enhance memory, if caffeine is over the amount that heart, high blood pressure, kidney and coronary artery would be caused a negative impact. In this paper, we use the special ultrasoun...
