PMMA/SWCNT Composites with Very Low Electrical Percolation Threshold by Direct Incorporation and Masterbatch Dilution and Characterization of Electrical and Thermoelectrical Properties.

In the present study, Poly(methyl methacrylate) (PMMA)/single-walled carbon nanotubes (SWCNT) composites were prepared by melt mixing to achieve suitable SWCNT dispersion and distribution and low electrical resistivity, whereby the SWCNT direct incorporation method was compared with masterbatch dilution. An electrical percolation threshold of 0.05-0.

Relationship of functional constipation and anal-retentive behavior features.

Objectives: Constipation is the most commonly seen defecation problem and related with several environmental factors. Learning defecation is learned in the childhood anal period in which anal characteristic features appear. Problems in the anal period of childhood may affect not only the characters but also the defecation function.
