The disclosure concerns a system including a modular dispensing system, at least one dispensing head at a counter, a transfer unit located remotely from the counter, and piping extending from the transfer unit to the counter. The airport-located subsystems are coupled by way communication paths, such as land line telephone links, to a remote flight operations control center. The increased surface area of the spinneret hole contacting the lower viscosity polymer flow compensates for the viscosity differential between the polymer components that would otherwise result in dogleg bending of the extrudate. A second metal layer formed on the electrode layer and the electrode layer are patterned by using a second half-tone mask or the gray-tone mask to form an upper circuit pattern, a sourcedrain pattern and an upper capacitance pattern. The processor also commands the modulating shut-off valve to move to the initial open position, determines when a predetermined event occurs, and commands the modulating shut-off valve to remain in the initial open position until the predetermined event occurs period. Particularly, foods and other oral products or treatments containing sporulation-deficient Brevibacillus strain when administered to a subject can inhibit or reduce the number of pathogens in the subject and improve the health of the subject.
