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)
Over the last decade, rates of opioid pain reliever prescribing grew substantially in the United States, affecting many segments of the population, including pregnant women. Nationally, Tennessee ranks second in the rate of prescriptions written for opioid pain relievers, with 1.4 per person in 2012. The rising prevalence of opioid pain reliever use and(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)
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)
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)
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)
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)
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)
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)
