Chapin Wrought Iron

Art - Chapin (Q)

Pioneering studies suggested that motor information in the cortex is coded through the combined actions of large populations of widely tuned neurons rather than by small numbers of highly tuned neurons1. Several systems provide further evidence for this ‘distributed coding’ in brain function2,3. However, such investigations used serial recordings of single neurons averaged over repeated trials,...

Variability of the Mechanical Properties of Wrought Iron from Historic American Truss Bridges

The mechanical properties of wrought iron from multiple elements of six late 19th-century truss bridges is evaluated by a program of destructive and nondestructive testing, including hardness testing and tension tests to evaluate the yield stress (Fy), tensile strength (Fu), and ductility of the material. The yield stress and tensile strengths are found to be in accordance with those published ...

New Species of Canthonella Chapin (scarabaeidae: Scarabaeinae) from Amazonian Brazil

Canthonella amazonica and C. leptoculata, new species of canthonine dung beetles, are described from Brazil’s central Amazon region. A new key to the eight species that occur in South America is provided.
