Experimental investigation of the dynamic behavior of railway track with sleeper voids
Railway Engineering Science, 2020 The deterioration of the sleeper support on the ballasted track begins with the accumulation of sleeper voids. The increased dynamic loading in the voided zone and the ballast contact conditions cause the accelerated growth of the settlements in the ...

Livestock Tango: U.S. and Latin America Dance Together, but Who Will Lead?
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT This study examines the competitiveness between Latin American and U.S. livestock and meat sectors. We employ a computable general equilibrium modeling framework to evaluate two scenarios: coordinated improvements in Latin American productivity, transport efficiency, and market access (Scenario I), and the minimum productivity gains required ...
