Northwestern University developed copper-precipitation-hardened, high-performance weathering steel (NUCu 70W Steel) that is produced by hot rolling after casting and then air-cooling. Due to simple processing the steel is fabricated at lower cost than competing high-performance steels that require quench and tempering. NUCu 70W steel can be easily welded without pre-...
This brochure contains information on the NUCu Steel ASTM A-710 Grade B project published at Northwestern University's Infrastructure Technology Institute with the support of the Illinois Department of Transportation. The brochure includes further explanation to Current and Potential Applications, Chemical Composition and Steel Processing, Mechanical and Fracture Properties, Corrosion, Welding,...

Experimental Time Domain Reflectometry (TDR) data obtained from the field are compared with numerical simulations using a finite-difference solution of the transmission line equations. The model simulates transmission of a voltage pulse along a lossy coaxial cable where deformities on the cable, such as crimps and shears, are represented by...
How can gatekeeping theory in the circulation of cultural objects, including knowledge production, inform the way cultural sociology investigates the role of the producer and the cultural object as “gated” entities? Using the case of producers working under the rubric of “Contemporary African art” to investigate opportunities and restrictions to...
In his essay on Mali, Bruce Whitehouse of Lehigh University shows how failures of elected leaders, state institutions, and external donors can shift power to the streets and an uncertain contest among armed forces.
This presentation is intended to provide background on the principles involved in geotechnical and infrastructure applications of Time Domain Reflectometry (TDR). TDR is basically radar in which a voltage pulse is launched along a coaxial cable. A reflection of the voltage pulse occurs at every location where the cable is...
