On- and off-road mobile sources are the dominant contributors to urban anthropogenic volatile organic compound (AVOC) emissions. Analyses of gasoline samples from California for both summer and winter indicate significant differences in liquid fuel and vapor chemical composition due to intentional seasonal adjustments. Ambient concentrations of 55 VOCs were(More)
Ambient concentrations of eight predominantly anthropogenic halocarbons were measured via in situ gas chromatography in California's South Coast air basin for both summer and fall during the 2005 Study of Organic Aerosols at Riverside (SOAR). Ongoing emissions of the banned halocarbons methylchloroform and CFC-11 were observed in the South Coast air basin,(More)
BACKGROUND Childhood cancer survivors may have premature symptomatic cardiovascular and non-cardiovascular diseases that contribute to reduced capacity for physical activity. Studies of exercise capacity and identification of risk factors for reduced capacity in survivors are limited. PROCEDURE We assessed maximal myocardial oxygen consumption(More)
Lifetimes of the lowest excited singlet (S1) electronic states of various derivatives of the pyrimidine nucleobase cytosine (Cyt) were measured by the femtosecond transient absorption technique. The bases were excited in room-temperature aqueous solution at 265 nm using approximately 200 fs pump pulses from a titanium-sapphire laser system. The decay of(More)
Kinetics studies of the OH-initiated oxidation of 2-butyne, propyne, and acetylene were conducted at 100 Torr and 298 K using turbulent flow chemical ionization mass spectrometry. The major oxidation products were identified, and with the aid of supporting electronic structure thermodynamics calculations, a general OH-initiated oxidation mechanism for the(More)
ACKNOWLEDGEMENTS Several individuals from the California Air Resources Board contributed to this project. We particularly want to thank Nehzat Motallebi for her steadfast encouragement and useful input throughout the contract period, along with William Vance and Chris Jakober for providing useful comments on the draft version of this report. The success of(More)
Thirteen percent of women experience postpartum depression. Prenatal screening for anticipated postpartum social support, a postpartum depression risk factor, may allow for early intervention. We sought to validate use of a modified version of the Postpartum Social Support Questionnaire (PSSQ) in pregnant women at increased risk for postpartum depression.(More)
Workforce development is a priority across many state Maternal and Child Health (MCH) Title V programs. Three case studies were conducted to explore varied state implementations of MCH workforce development initiatives. Three states utilized the online MCH Navigator resource to support orientation and ongoing professional development for staff and other(More)
The overall rate constants of the NO reaction with hydroxyalkylperoxy radicals derived from the OH-initiated oxidation of several atmospherically abundant alkenes—ethene, propene, 1-butene, 2-butene, 2-methyl propene, 1,3-butadiene, and isoprene (2-methyl-1,3-butadiene)—were determined using the turbulent flow technique and pseudo first-order kinetic(More)
Objectives Vitamin K deficiency bleeding (VKDB) in infants is a coagulopathy preventable with a single dose of injectable vitamin K at birth. The Tennessee Department of Health (TDH) and Centers for Disease Control and Prevention (CDC) investigated vitamin K refusal among parents in 2013 after learning of four cases of VKDB associated with prophylaxis(More)
