An insulated concrete form including of first and second spaced sidewalls forming a cavity therebetween, said sidewalls having an inside surface and interconnected by a plurality of form ties, and a form insert made of an insulative material positioned adjacent the inside surface of at least one sidewall which thereby increases the R-value of the resulting structure. The system has an arrangement of UV light emitters on perforated plates. When the wafers are vertically stacked, the upper channels of one wafer complementally form ducts with the lower channels of another wafer, each duct having an outlet or port in communication with the exterior of the terminal block. The third display area is for displaying at least two adjustable attribute values of a selected output property in a property adjust mode. New compositions of matter which comprise the propanoates, prepared in the above manner, have application in the electronic chemicals market such as in a photoresist composition.
