Factors affecting maternal decision making about grandparents' cariogenic dietary choices for children: A qualitative study.

Background: Added sugar in children's diets puts them at higher risk of developing caries. Researchers have reported that grandparents frequently give their grandchildren cariogenic foods and beverages (for example, those with added sugars) and disagreements between grandparents and parents can ensue over this issue. This study's objective was to examine factors that influence whether mothers address grandparents about giving their grandchildren cariogenic foods and beverages.

Exploring Mothers' Perspectives About Why Grandparents in Appalachia Give Their Grandchildren Cariogenic Foods and Beverages: A Qualitative Study.

Background: Dental caries is the most common chronic childhood disease. Past studies revealed that grandparents provide their grandchildren with cariogenic foods and beverages (eg, those with free sugars and/or modified starches). Qualitative research can help identify what drives this phenomenon.

Fabrication and Characterization of a Pb-Sn Nanowire Array for Detecting Carbon Monoxide.

In this study, a Pb-Sn alloy nanowire of 80 nm in diameter and 50 microm in length is obtained by an anodic aluminum oxide nanomold and vacuum die casting method. The upper and lower ends of the prepared Pb-Sn alloy nanowire array are vapor deposited with 3 microm of copper thin film, which serves as the conductive layer of the gas sensor. Experimental results show that the sensitivities of 3 gas sensors fabricated by 3 different Sn-Pb alloy nanowire arrays, namely Sn70%-Pb 30% wt, Sn63%-Pb 37% wt and Sn50%-Pb 50% wt, for detecting a carbon monoxide concentration of 500 ppm under a working temperature of 250 degrees C, were 17.
