Array flow stages

Continuous-contact operations are diametrically different from staged operations in almost every aspect. The two phases are in continuous flow and in continuous contact with each other, rather than repeatedly separated and re-contacted in an array of stages. Second, the attainment of equilibrium is shunned. An active driving force is maintained at all times and its constituent concentrations vary continuously from the point of entry to the exit. The result is that the concentrations are now distributed in space and, assuming a normal steady-state operation, are invariant in time. Thus, while staged operations vary at most with time, but not at all with distance, the exact opposite holds in continuous-contact operations.

Feed pressure This is the projected pressure required to the first stage of the RO system. The pressure is a function of the flow rate, water temperature, array, and fouling factor selected. 

Figure 4 presents one possible scenario for work flow in studying the metabolic competence of living cells, but naturally, equally valid variations can easily be designed. In this task, a comprehensive, routine, and easy technique is preferable as an early stage of characterization. PCR-based arrays are relatively robust and reliable for screening the relative expression of desired mRNAs, and this would give the first...
