Slider modules

Fig. 1 Examples of screens captured from the (a) static (b) animated and (c) interactive versions of the online chemistry learning module. The static version uses still pictures only. The animated version requires students to select Play (see highhght in (b)) and watch an animation that shows a representation of the ionization of an acid. The interactive version gives students control of the animation that shows the ionization of an acid by moving a slider bar (see highhght in (c)). In this version, students are able to stop the animation as they please to help them vdth their understanding...

The STM used in this work was constructed in our laboratory [13]. Mechanically, it consists of two main modules a scanner and a coarse positioner. The scanner part is constructed with a PZT tube (EBL 3 PZT-5H, Staveley Sensors, CT) glued to an aluminium body. Electrical connection of PZT is through a special connector. The tip holder is also glued to the interior of the PZT tube but isolated electrically. The coarse positioner is a magnetically driven slider, which is fastened to the scanner and the whole system is mounted on a vibration isolation stage. 

The ExpressFX Amplitude Modulation plug-in has only a Rate, Depth, and Wet/Dry mix slider and lacks the other controls of the XFX version of this plug-in. 

The acceptance tested spacecraft and the certified fueled reactor module were to be received by KSC. The electrically heated power unit was to be replaced with the fueled power unit. Cutting and seal welding these joints was considered a critical, complex task, requiring extensive preparation and training. The HeXe coolant is purified, loaded, and sealed into the RM. Final functional, electrical, and software checks were to be performed. A preference existed to perform slider motion checks and zero-power critical tests at KSC prior to launch if this is appropriate from a regulatory standpoint (this issue had not been resolved at the time of project termination). The assembled spacecraft was to be mated to the launch vehicle and prepared for launch.
