Description of the Pulsed Acoustic Field of a Linear Diagnostic Ultrasound Array Using a Simple Apprmic union on June 1, 1990 and political union on October 3, 1990 brought a radical regime switch for Eastern Germany; this switch, however, was mitigated by transitory regulations in many fields (e.g. environmental protection and labor market regulations) and a massive West-East transfer of resource

Comparisons of extrapolation results with measured data and with theoretical predictions show reasonable agreement and also demonstrate the sensitivity of

However, no experimental procedure has been established so far for direct determination of the two quantities of both velocity and attenuation from V(z) curves.
