Oral Health Literacy and Dental Care among Low-Income Pregnant Women.

In this study, we sought to determine the impact of oral health literacy (OHL) on use of prenatal dental care and knowledge, understanding, and practices related to preventing dental caries (tooth decay) among low-income pregnant women in Maryland. We conducted a mixed methods study using a survey and a structured guide for one-on-one interviews or focus groups. The study included 117 pregnant women and was conducted between July 2016 and April 2018 in Maryland.

Sensor transition failure in the high flow sampler: Implications for methane emission inventories of natural gas infrastructure.

Unlabelled: Quantification of leaks from natural gas (NG) infrastructure is a key step in reducing emissions of the greenhouse gas methane (CH4), particularly as NG becomes a larger component of domestic energy supply. The U.S.

Direct measurements show decreasing methane emissions from natural gas local distribution systems in the United States.

Fugitive losses from natural gas distribution systems are a significant source of anthropogenic methane. Here, we report on a national sampling program to measure methane emissions from 13 urban distribution systems across the U.S.
