Railroad Transportation

SMO: Special Focus On Transportation and Cargo 11/06

The largest and fastest growing global economies around the world include Brazil, Russia, India, and China (BRIC). These countries, along with other high-tech manufacturing centers such as Malaysia and Indonesia, are attractive to companies both as a source of supply and as new markets to sell into. Before companies enter these inviting markets, however, they must understand the risks of operat...

Colloidal caterpillars for cargo transportation.

Tunable transport of tiny objects in fluid systems is demanding in diverse fields of science such as drug delivery, active matter far from equilibrium, and lab-on-a-chip applications. Here, we report the directed motion of colloidal particles and self-assembled colloidal chains in a nematic liquid crystal matrix using electrohydrodynamic convection (EHC) rolls. The asymmetric distortion of the ...

Railroad transportation of dangerous goods: Population exposure to airborne toxins

Hazardous materials are potentially harmful to people and environment due to their toxic ingredients. Although a significant portion of dangerous goods transportation is via railroads, prevailing studies on dangerous goods transport focus on highway shipments. We present an analytical framework that incorporates the differentiating features of trains, notably volume and nature of cargo, in the ...
