FRET requires the use of two fluorescent dyes, one termed a donor and the other an acceptor. In the FRET system, the donor dye (D) absorbs a photon to generate an excited state (D*).
Part 1 identified the respondent as a handbill acceptor or nonacceptor.
Walsh, head of the contract services department logistics directorate at the National Naval Medical Center Bethesda, and the WAWF group administrator and acceptor, enjoys the availability of the implementation team, describing implementation as "seamless and transparent." With the new electronic process, the margin for human error is gone since the system finds the errors.
The carbohydrates used included three new preparations synthesized from alternansucrase (asr)--maltose acceptor product, raffinose acceptor product and low mass alternan--and three commercial products: Benefiber, Fibersol-2 and Neosugar.
Charlie Mann supplies the remaining acceptor in the shape of nine-year- old Dunston Bill.
West Chester, Pa.-based MEI, a developer of electronic cash payment systems, says its cash acceptor has been installed in 69 coin-counting kiosks in grocery stores in Sacramento, Calif., Tampa, Fla., and Providence, R.I.
One exciting discovery is that substituting tin oxide ([SnO.sub.2]) for [TiO.sub.2] sufficiently chang es the acceptor levels and electronic coupling efficiencies to produce cells with absorbed photon-to-current efficiencies approaching 40 %, constant across the visible spectrum.
So if more than one method is available, and acceptor can switch over to a more suitable method of choice if the first (or previous) method of choice becomes unacceptable.
For years, scientists have been able to store light energy chemically using systems that utilize the ability of a donor molecule--one that becomes charged when exposed to light--to transfer its electric charge to an acceptor molecule.
Key statement: A tire component comprising a rubber composition having a highly unsaturated diene elastomer and a reinforcing filler with a first methylene acceptor selected from 3-hydroxydiphenylamine, 4-hydroxydiphenylamine or combinations thereof; a second methylene acceptor selected from a Novolac resin, diphenylolmethane, diphenylolethane diphenylolpropane, diphenylolbutane, a naphthol, a cresol or combinations thereof and a methylene donor.
