    摘要: Providing water management services includes generating a water accounting model. The model is generated by selecting data, via a user interface implemented by a computer processor, from options including water quality, water quantity, and water usage. The model is further generated by defining, via the user interface, parameters of the data for a geographic region, and defining, via the user interface, actions to be taken. Providing the water management services further includes mapping communications addresses of data sources of data selected via the user interface to the water accounting model, receiving input values for the data via the communications addresses from the data sources, executing the water accounting model, and identifying and implementing an action responsive to results of executing the mode.

    摘要: A prepolymer for use in preparing photocurable compositions is prepared by reacting an aliphatic diisocyanate having terminal isocyano groups and at least one alkyl side chain with a hydroxy-, mercapto- or amino-containing olefinically unsaturated compound. This prepolymer is compounded with a photosensitizer and, optionally, a polymercaptan to prepare photocurable compositions.
