LCCA and environmental LCA for highway pavement selection in Colorado
International Journal of Sustainable Engineering, 2014 The roadway network in the USA earned a grade of D representing poor condition in the latest report card from the American Society of Civil Engineers. To maintain economic and environmental sustainability during the roadway network development and rehabilitation, it is critical to apply sustainable materials and intelligent design. A good estimation on

Relativistic Quark Spin Coupling Effects in the Nucleon Electromagnetic Form Factors
, 1999 We investigate the effect of different forms of relativistic spin coupling of constituent quarks in the nucleon electromagnetic form factors. The four-dimensional integrations in the two-loop Feynman diagram are reduced to the null-plane, such that the ...
