Data supporting the morphological/topographical properties and the degradability on PET/PLA and PET/chitosan blends.

These data display evidence of the fracture through the morphologies and the topographical features as well as roughness data of different ratios of R(recycled)-PET/PLA, PET(virgin)/PLA, PET(virgin)/Chitosan and R(recycled)-PET/chitosan. Also, data of the morphologies after degradation under accelerated weathering test and degradation mechanisms are revealed. The data supplement the article "Comparative assessment of miscibility and degradability on PET/PLA and PET/chitosan blends".

Perceptions of children's body sizes among mothers living on the Texas-Mexico border (La Frontera).

Objectives: The objectives of this study were to quantify mothers' perceptions of their children's sizes and explore mothers' views of child growth, diet, activity, and health. Photographs of children from the Berkeley Longitudinal Growth Study (on Centers for Disease Control and Prevention [CDC] Web site) were used to stimulate discussion with mothers about child sizes.

Design: A descriptive, cross-sectional study examined mothers' perceptions of their children's size and their beliefs about child size, growth, and health.
