Directives border controls

Hardly any of the countries bordering Afghanistan reported seizures of acetic anhydride during 2005 and 2006. The lack of evidence linking seizures of acetic anhydride to diversions directly from international trade raises concern over the controls exercised by Governments to prevent diversions from domestic distribution channels. Governments are therefore urged to ensure that the distribution and consumption of acetic anhydride at the national level are properly controlled. 

Analysis and control of ultrafast processes in atomic clusters in the size regime in which each atom counts are of particular importance from a conceptual point of view and for opening new perspectives for many applications in the future. Simultaneously, this research area calls for the challenging development of theoretical and computational methods from different directions, including quantum chemistry, molecular dynamics, and optimal control theory, removing borders between them. Moreover, it provides stimulation for new experiments. 

For experimental observation of the drainage and stability of liquid films the capillary cell illustrated in Fig. 16 is widely used (Scheludko and Exerowa 1959). First, the cylindrical glass cell is filled with the working liquid (say, water solution) next, a portion of the liquid is sucked out from the cell through the orifice in the glass wall. Thus, in the central part of the cell a liquid film is formed, which is encircled by a Plateau border. By adjustment of the capillary pressure the film radius, / , is controlled. The arrow (see Fig. 16) denotes the direction of illumination and... 

Metal-focusing process after the sample injection is shown in Fig. 3. After all the ions in the sample are extracted onto the stationary phase, mobile phase is introduced in to the column. Ammonia in the stationary phase begins to be neutralized with hydrochloric acid in the mobile phase. The neutralization area, where reaction between the acid and the base has just finished, is shown as pH border in Fig. 3. The pH border moves from left to right (the same direction as the mobile phase) however, its flow rate is lower than that of the mobile phase because of the delay caused by the neutralization of the acid in the mobile phase by the base in the stationary phase. Therefore the flow rate of the pH border may be controlled by adjusting the concentration of base and acid in the respective phase.
