Occupational Exposure of Workers to

J.M. Fajen, Dennis R. Roberts, E. Radha Krishnan

extent-of-exposure study of the 1,3-butadiene monomer, polymer, and end-user industries to determine the size of the exposed workforce, evaluate control technologies and personal protective equipment programs, and assess occupational exposure to 1,3-butadiene. A new analytical method was developed for 1,3-butadiene that increased …

Observation of the decay B[over ¯]^{0}→Λ_{c}^{+}p[over ¯]π^{0}

B. Aubert, Y. Karyotakis, J. P. Lees, V. Poireau et autres

In a sample of 467×106 BB̅ pairs collected with the BABAR detector at the PEP-II collider at SLAC we have observed the decay B̅ 0→Λc+p̅ π0 and measured the branching fraction to be (1.94±0.17±0.14±0.50)×10-4, where the uncertainties are statistical, systematic, and the …

Searches for B0 decays to ηK0, ηη, η′η′, ηϕ, and η′ϕ

B. Aubert, M. Bóna, D. Boutigny, F. Couderc et autres

We search for B0 meson decays into two-body combinations of K0, η, η′, and mesons in 324×106 BB̄ pairs collected with the BABAR detector at the PEP-II asymmetric-energy e+e- collider at SLAC. We measure the following branching fractions (upper limits at 90% …

Production and Decay of Ξ0c at BABAR

B. Aubert, R. Barate, D. Boutigny, F. Couderc et autres

Using 116.1 fb(-1) of data collected by the BABAR detector, we present an analysis of xi(c)(0) production in B decays and from the cc continuum, with the xi(c)(0) decaying into omega- K+ and xi- pi+ final states. We measure the ratio of …

Mortality among rubber chemical manufacturing workers

Mary M. Prince, Elizabeth Ward, Avima M. Ruder, Alberto Salván et autres

BACKGROUND: A retrospective cohort mortality study evaluated ischemic heart disease (IHD) among workers in the "rubber chemicals" manufacturing department of a Western New York plant. A previous study at the plant found elevated chest pain and angina among workers in this department. …

Screening and analysis for high levels of volatile organic compounds using compendium method TO14

Matthew Booth, Glen P. Jackson, Dennis R. Roberts, Margrethe Winslow

Compendium method TO14 is the EPA`s recommended guidance method for the sampling and determination of volatile organic compounds (VOCs) in ambient air samples collected in SUMMA{reg_sign} passivated canisters. In addition to samples containing ambient levels of VOCs, many air samples with VOC …

Study of gluon versus quark fragmentation in Υ→ggγ and e+e−→qq¯γ events at s =10 GeV

M. S. Alam, S. B. Athar, Z. Ling, A. H. Mahmood et autres

Using data collected with the CLEO II detector at the Cornell Electron Storage Ring, we determine the ratio ${R}_{\mathrm{chrg}}$ for the mean charged multiplicity observed in $\ensuremath{\Upsilon}(1S)\ensuremath{\rightarrow}\mathrm{gg}\ensuremath{\gamma}$ events, $〈{n}_{\mathrm{gluon}}^{\ifmmode\pm\else\textpm\fi{}}〉$, to the mean charged multiplicity observed in ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}q\overline{q}\ensuremath{\gamma}$ events, $〈{n}_{\mathrm{quark}}^{\ifmmode\pm\else\textpm\fi{}}〉$. We find ${R}_{\mathrm{chrg}}\ensuremath{\equiv}〈{n}_{\mathrm{gluon}}^{\ifmmode\pm\else\textpm\fi{}}〉/〈{n}_{\mathrm{quark}}^{\ifmmode\pm\else\textpm\fi{}}〉=1.04$ …

Industrial exposure to 1,3-butadiene in monomer, polymer and end-user industries.

J.M. Fajen, R A Lunsford, Dennis R. Roberts

Researchers from the National Institute for Occupational Safety and Health (NIOSH) of the Centers for Disease Control and Prevention conducted an extent-of-exposure study of 1,3-butadiene monomer, polymer and end-user industries to assess occupational exposure to butadiene and to evaluate control technologies. The …
