Voltammetric determination of the ion-exchange behavior of poly(ester sulfonic acid) anionomers in acentonitrille
(The American Chemical Society: Analytical Chemistry, 1990-10-01) -
W-reactivation of phage lambda in recF, recL, uvrA, and uvrB mutants of E. coli K-12
(Springer: Molecular and General Genetics, 1979-01)W-reactivation is reduced by recF143 and recF144 mutations and is undetectable if a second mutation at either the uvrA or uvrB locus is combined with recF143. The uvrA and uvrB mutations alone block W-reactivation partially. ... -
The warped nuclear disk of radio galaxy 3C 449
(Astrophysical Journal, 2006)Among radio galaxies containing nuclear dust disks, the bipolar jet axis is generally observed to be perpendicular to the disk major axis. The FR I radio source 3C 449 is an outlier to this statistical majority, as it ... -
Water balance of terrestrial anuran (Eleutherodactylus Coqui) eggs: importance of parental care
(The Ecological Society of America: Ecology, 1984-02)The terrestrial eggs of the coqui of Puerto Rico are brooded almost continuously by the male parent from the time of oviposition until the fully metamorphosed hatchlings emerge from the eggs 15-20 d later. The gelatinous ... -
Why design an accessible web site?
(IGI Global, 2001-12)It is easy for those of us who lead unencumbered lives to forget what it must be like to be denied daily activities that we take for granted - to be relegated to the sidelines of society. Nearly half of those with disabilities ... -
X-ray diagnostics of pre-main sequence accretion and outflow activity
(2005-07)I summarize the mounting evidence for a direct link between pre-main sequence (pre-MS) X-ray emission and pre-MS accretion and outflow processes. Such a link is supported by three lines of observational inquiry rendered ... -
An X-ray outburst from the rapidly accreting young star that illuminates McNeil's Nebula
(Nature, 2004-07-22)Young, low-mass stars are luminous X-ray sources1 whose powerful X-ray flares^(2-6) may exert a profound influence over the process of planet formation^(7). The origin of such emission is uncertain. Although many or ... -
X-ray properties of B2 1028+313: a quasar at the center of the Abell cluster A1030
(American Astronomical Society, 1999-01-01)X-ray observationswith the ROSATHRI and with ASCA are presented for the nearby radio quasar B2 1028+313, which is located in the cD galaxy at the center of the Abell cluster A1030. We also analyze archival ROSAT ... -
YZGD from Paenibacillus thiaminolyticus, a pyridoxal phosphatase of the HAD (haloacid dehalogenase) superfamily and a versatile member of the Nudix (nucleoside diphosphate x) hydrolase superfamily
(Portland Press: Biochemical Journal, 2006-03-15)YZGD from Paenibacillus thiaminolyticus is a novel bifunctional enzyme with both PLPase (pyridoxal phosphatase) and Nudix (nucleoside diphosphate x) hydrolase activities. The PLPase activity is catalysed by the HAD (haloacid ... -
Zirconium pendent poly(amic acid) and polyimide based on 3,4'-ODA and ODPA
(The American Chemical Society: Polymer Preprints, 2000-03)Aromatic polyimides long been attractive for applications in the aerospace and electronic industries. But many polyimide materials are readily oxidized by atomic oxygen (AO) in low earth orbit (LEO) because neutral atomic ...
