One feature of the European patent system that is heavily criticized nowadays is related to its complex fragmentation and the induced cost burden for applicants. Once a patent is granted by the EPO, the assignee must validate (and often translate) it and pay the renewal fees to keep it in force in each country in which the applicant seeks protection. The objective of this paper is to assess to ...
Using a gravity model, we estimate the magnitude of potential trade flows between Ireland and the five CEEC countries currently negotiating accession to the EU. We find that Irish exports were already close to their “normal” level in 1994, but that imports from the CEECs were still only half of their “normal” size. The value of estimated “normal” trade corresponds to 0.8 percent of Irish GNP. T...
The mechanism of the formation for cocurrent downflow pulse flow was studied experimentally in a packed-bed of inert spheres of 3, 6, and 8 mm using an air-water flow. By measuring the flow distance until pulses are observed, the spatial growth rate of convective disturbances within the pulsing-flow regime were determined. Observations indicate that pulses form from trickling-flow as the result...
