A more informative approach for characterization of polymer monolithic phases: small angle neutron scattering/ultrasmall angle neutron scattering.

Neutron scattering techniques have been used frequently to characterize geological specimens and to determine the structures of glasses and of polymers as solutions, suspensions, or melts. Little work has been reported on their application in determining polymers' structural properties relevant to separations. Here, we present a comparison of characterization results from nitrogen porosimetry and from combined small angle neutron scattering (SANS) and ultrasmall angle neutron scattering (USANS) experiments.

A long-acting human growth hormone (Nutropin Depot): efficacy and safety following two years of treatment in children with growth hormone deficiency.

Background: Nutropin Depots [somatropin (rDNA origin) for injectable suspension] is a long-acting form of human growth hormone (GH) to be administered by subcutaneous (s.c.) injection.

Compliance of licensed child care centers with the American Academy of Pediatrics' recommendations for infant sleep positions.

Sudden Infant Death Syndrome is an elusive and tragic cause of infant mortality. In 1992, the American Academy of Pediatrics (AAP) recommended that healthy term infants be placed in the supine or lateral positions for sleep, based on research conducted in Europe, Australia, and New Zealand. The AAP modified its recommendation in 1994, indicating a preference for the supine position.
