Again, the characteristics of the system need to be considered. The weight of the machine and the frequency will determine the static and dynamic deflections of the mounts and hence the material of which the mount is to be constructed. At very high frequencies mats may be placed under machinery, and these may consist of mbber, cork or foam. At middle frequencies it is usual to use mbber in-shear mounts. At low frequencies metal spring mounts are employed. 

B. Long-term potentiation in the dentate gyrus recorded in vivo. The graph plots the early rising slope of the field excitatory postsynaptic potential (EPSP) in response to low frequency stimulation (700 pA, 100 ms, 0.05 Hz). Four trains of high frequency stimulation (700 pA, 82.5 ms, 400 Hz) were dehvered at time 0. This produced an immediate increase in the EPSP slope (post-tetanic potentiation) and a sustained relatively constant enhancement that lasted for at least 60 minutes. Representative traces are included below the graph. Note the obvious increase in size of the superimposed population spike (downward deflection). 

The PIMMS-elements can be divided in the fields of fluidic, plasma physics, electrostatic, and high frequency technology. The fluidic part covers the supply with plasma and sample gas, their distribution inside, and their evacuation out of the system. By means of plasma physics both the ionization of the plasma gas by the microwave field and the ionization of the sample gas by impact ionization are described. Electrostatic theory governs to design the elements for acceleration, focusing, and deflection of the plasma electrons and the sample gas ions. Electromagnetic wave theory describes the creation of a microwave-field inside the plasma chamber. 

TV deflection yokes are used in display monitors to focus electrons through the interaction with a strong magnetic field, and create an image on the screen. The requirements for the ferrite element in yokes are similar to those for high-frequency transformers since the image resolution has a direct relation with the frequency needed in the horizontal scanning. A resolution of 2.5 x 10 pixels is achieved with a horizontal frequency of...
