(fructo-Oligosaccharides) - a prebiotic, or sugar that encourages friendly bacteria to multiply, acting as a fertilizer in the intestines. These nutrients help nourish the "good bacteria" so they can make healthy by-products to nourish the intestine.
Full Operating Status. Ships are fully operational, with complete crews aboard. Ships are FOS after they have been fully activated.
Clinical studies have shown that supplementation with FOS can increase the number of friendly bacteria in the colon while simultaneously reducing the population of harmful bacteria.
Family of Services. Since 1983, the National Weather Service (NWS) has provided external user access to U.S. Government obtained or derived weather information through a collection of data communication line services called the Family of Services (FOS). All FOS data services are driven by the NWS Telecommunication Gateway computer systems located at NWS headquarters in Silver Spring, MD. Users may obtain any of the individual services from NWS for a one-time connection charge and an annual user fee. Several private companies subscriber to the FOS and then resell the data as received and/or provide value-added information services for their customers.
Faint Object Spectrograph - - First Generation Spectrometer. FOS was used to obtain spectra of very faint or far away sources. FOS also had a polarimeter for the study of the polarized light from these sources
FOS stands for fructo-oligosaccharides, which are a type of sugar that is not digested in the small intestine but passes through to the colon and there is selectively used as a food source by beneficial bacteria such as bifidus and acidophilus.
FAINT OBJECT SPECTROGRAPH. The spectrograph aboard the Hubble Space Telescope designed to study faint objects, using two "Digicon" systems of detectors, one sensitive to reddish visible light and one sensitive to bluish visible light and ultraviolet radiation.
Faint Object Spectrograph. An instrument aboard the Hubble Space Telescope that acted like a prism to separate light from the cosmos into its component colors, providing a wavelength 'fingerprint' of the object being observed. Such information yields clues about an object's temperature, chemical composition, density, and motion. Spectrographic observations also reveal changes in celestial objects as the universe evolves. The instrument was replaced in February 1997 during the Second Servicing Mission.
