This thesis investigated the methods of failure in the webs of
built up girders. The beams had rectangular holes five and one-half
inches wide and seven and one-half inches high with rounded corners
in a web fourteen inches deep between flanges. The longitudinal
position of the hole edge varied from...
The miniaturization of energy, chemical and biological systems for distributed and portable applications, known as process intensification, is realized by the enhancement in heat and mass transfer performance within high surface-to-volume ratio microchannels. Fabrication of devices for process intensification is achieved in part by microlamination techniques. These techniques consist of...
