Given its vapor pressure, toluene tends to partition to the atmosphere. Automobile emissions are the principal source of toluene in ambient air, with levels fluctuating in proportion to automobile traffic. Toluene can also be a common indoor contaminant, and indoor air concentrations are often several times higher than outside air. This is likely due to release of toluene from common household ...

OBJECTIVE To estimate whether air-bag deployment is associated with an increased risk of adverse pregnancy outcomes. METHODS We performed a retrospective cohort study to assess the effect of air-bag availability and air-bag deployment on the risk of adverse pregnancy outcomes among pregnant, front-seat occupants in motor vehicle crashes in Washington State. Pregnant women involved in motor ve...

OBJECTIVE To estimate the association of driver air bag presence with driver fatality in road traffic crashes. DESIGN Matched pair cohort study. SETTING All passenger vehicle crashes in the United States during 1990-2000 inclusive. SUBJECTS 51 031 driver-passenger pairs in the same vehicle. MAIN OUTCOME MEASURES Relative risk of death within 30 days of a crash. RESULTS Drivers with an...

A laboratory experiment was conducted with bean seeds kept in three different containers viz. tin pot, poly bag and jute bag and stored at room temperature and RH for three months in the Laboratory of Agronomy Department, Sher-eBangla Agricultural University to study their storage behavior, germination percentage and quality. The seed of jute bag came to the contact with air and their moisture ...

OBJECTIVE Public concern has arisen about the reliability of front air bags because Fatality Analysis Reporting System (FARS) data indicate many nondeployed air bags in fatal frontal crashes. However, the accuracy of air bag deployment, the variable in question, is uncertain. This study aimed to provide more certain estimates of nondeployment incidence in fatal frontal crashes. METHODS Fatall...

BACKGROUND AND OBJECTIVES The effectiveness of air bags as a safety device in decreasing fatalities and reducing morbidity in frontal impact motor vehicle accidents has been well established. However, case reports have surfaced documenting ocular injuries related to air bag inflation. The purpose of this study was to identify and analyze ocular injuries sustained during air bag inflation. PAT...

We studied National Trauma Data Bank data to determine the effectiveness of car safety devices in reducing mortality and injury severity in 184,992 patients between 1988 and 2004. Safety device variables were seat belt used plus air bag deployed; only seat belt used; only air bag deployed; and, as explicitly coded, no device used. Overall mortality was 4.17%. Compared with the no-device group, ...

A plastic bag method was developed to observe air-sensitive samples on microstructure and phase distribution without exposure to air during the holder transfer process into the transmission electron microscope (TEM). As an example, a type of lithium aluminum hydride (Li(3)AlH(6)) was observed in the TEM to demonstrate the effectiveness of this method. Results show that the plastic bag method is...

Deployment of the air bag in a passenger vehicle accident rarely causes otologic injuries. However, sensorineural hearing loss induced by air bag deployment is extremely rare, with only a few cases reported in the English literature. A 38-year-old man involved in a traffic accident while driving his car at 40 km/hour presented with right sensorineural hearing loss and tinnitus, without associat...
