A series of tests on cold-formed steel foamed concrete (CSFC) composite walls subjected to axial load were proposed. The primary purpose of the experiments was to study the mechanical behavior and identify the failure modes of CSFC composite walls. Two main factors were considered in this study: 1) specimen with pouring foamed concrete or without and 2) different foamed concrete density ranks (...

This column focuses on the valid, reliable, and useful measurement of treatment effects in children and adolescents with attention-deficit/hyperactivity disorder (ADHD) treated in practice settings. Recall that the composite case of Polly refers to an 11 year-old female who was evaluated and determined to have probably met diagnostic criteria for ADHD, combined type (Frazier and Youngstrom, 200...

Iron oxide/activated carbon (FeO/AC) composite adsorbent material, which was used to modify the coal-based activated carbon (AC) 12 x 40, was prepared by the special ferric oxide microcrystal in this study. This composite can be used as the adsorbent to remove arsenic from drinking water, and Langmuir isotherm adsorption equation well describes the experimental adsorption isotherms. Then, the a...
