The Post-Curing of Waterborne Polyurethane-Acrylate Composite Latex with the Dynamic Disulfide-Bearing Crosslinking Agent.

The development of a dynamic network for commodity polymer systems via feasible methods has been explored in the context of a society-wide focus on the environment and sustainability. Herein, we demonstrate an adaptive post-curing method used to build a self-healable network of waterborne polyurethane-acrylate (WPUA) composite latex. The composite latex was synthesized via the miniemulsion polymerization of acrylates in the dispersion of waterborne polyurethane (PU), with commercial acetoacetoxyethyl methacrylate (AAEM) serving as the functional monomer.

Epidemic characteristics of main infectious diseases in Yantai city between 2010 and 2012 and prevention strategy research.

To investigate the epidemic characteristics and prevention strategies of main infectious diseases. From 2010 to 2012, 23 notifiable diseases were reported in Yantai with average reported cases of 17,376. The morbidity was the highest in 2012 and the lowest in 2011.

Estimation of salt intake by 24-hour urinary sodium excretion: a cross-sectional study in Yantai, China.

Background: High levels of dietary sodium are associated with raised blood pressure and adverse cardiovascular health. To determine baseline salt intake, we investigated the average dietary salt intake from 24-hour urinary sodium excretion with a small sample of Yantai adults in the Shandong province of China.

Methods: One hundred ninety one adults aged 18-69 years were randomly selected from the Yantai adult population.
