This paper poses and tests a new model of the location of plants that process ubiquitously supplied ‘von Thünen’ inputs such as raw farm output. The new model rationalizes why agro-industry is city-located but resource-oriented. It demonstrates the significance of relative transport costs in agroindustry location. Furthermore, we present a unprecedented direct test/empirical confirmation of est...

We present results from 200 hours of operation of an atmospheric super test beam system developed for the Pierre Auger Observatory. The approximate optical equivalence is that of a 100 EeV air shower. This new system combines a Raman backscatter LIDAR receiver with a calibrated pulsed UV laser system to generate a test beam in which the number of photons in the beam can be determined at ground ...
