Audiovisual policy transfer between Mercosur and the European Union has gone offtrack

This article analyses the Audiovisual Mercosur Program as a case of policy transfer between Mercosur and the European Union. A qualitative document analysis, expert interviews and the use of policy transfer theory and its constraints made possible the critical evaluation of the program and its impacts. By focusing on the constraints that led to an incomplete and uninformed transfer, we were able to identify an alignment between the underlying ideas of audiovisual policies in Mercosur and the European Union, but also inadequate governance within Mercosur, unbalanced interests between the two trade blocks, and a lack of policy learning. As a result, the transfer of European Union policies reproduced well-documented failures of the European Union's internal market policies relating to the audiovisual sector.

Comparison of Heat Transfer Theory, CFD and Experimental Results in the Design Process of High-Power Fiber Laser Cooling Plate

For the stabilization of laser output power and wavelength of the high power fiber laser, the cooling plate must be properly taken into account. In this study, three analyzing methods which are heat transfer theory, CFD and experiment are used to analyze cooling plate performance by measuring pump Laser Diode(LD) temperature. Under limited operating conditions of a cooling plate, the internal flow of cooling plate is transitional flow so that the internal flow is assumed to be laminar and turbulence flow and conducted theoretical calculation. Through CFD, temperature of pump LD and characteristics of the internal flow were analyzed. By the experiment, temperature of pump LD was measured in real conditions and the performance of the cooling plate was verified. The results of this study indicate that three analyzing methods are practically useful to design the cooling plate for the high power fiber laser or similar things.

The Broadband Albedo of Snow

The asymptotic radiative transfer theory is used to derive the analytical approximation for the broadband albedo of pure and polluted snow surfaces. The technique for the determination of the effective snow grain size and also the snow specific surface area from the shortwave broadband albedo measurements is proposed.
