Abstract: A digitally controlled aspirator is provided with a processor that allows the user to select operating conditions including one or more default settings. The processor further includes sensors for sensing operational and environmental conditions and adjusts the operation of the aspirator to reflect the sensed conditions.

Abstract: The present invention comprises a method, computer program product, and system for risk management. The present invention includes calculating a statistic of loss per unit time, the statistic being a product of a site loss parameter and a loss given a loss-basis event. The site loss parameter is a site casualty parameter and/or a site economic parameter, while the loss-basis event is a casualty-basis event and/or an economic-basis event, non-limiting examples of which include an earthquake, flooding, wind, and blast pressure.

Abstract: A universal aqueous composition and a process for using such a composition for pretreating metal substrates is provided. The aqueous composition includes a hydroxy functional cyclic compound, such as a tannin, in an amount of at least about 500 ppm, phosphate ions, an oxidizer-accelerator, and at least one Group IVB metal compound capable of converting to a metal oxide upon application to the metal substrate, such as a fluorozirconate or fluorotitanate. The composition may further contain fluoride ions and/or iron The composition is particularly useful for corrosion resistance with a variety of metals such as iron, steel; zinc-coated surfaces, aluminum, and alloys thereof. A disaccharide may further be provided to prolong the useful life of the composition, particularly when used in spray applications.
