Activity practical system

Water spray systems for hydrocarbon facilities are routinely specified because of the rapid application means the system can provide and the excellent heat absorption a water based system represents. Water sprays are also used when passive fire protection measures (i.e., fireproofing, spacing, etc.) cannot practically be utilized. The key to providing an effective system is to ensure the surfaces to be protected receive adequate water densities and that the arrangements to activate the system are equally fast acting. By far the highest...

Action of proving, in accordance with the principles of good manufacturing practice, that any procedure, process, equipment, material, activity, or system actually leads to the expected result Documented evidence which provides a high degree of assurance that a specific process will consistently produce a product meeting its predetermined specifications and quality attributes and characteristics... 

As mentioned previously (Ref 22) the use of Al-wax nose pads, 80/20 and 90/10, was investigated for use in AP shot in rifle bullet impact bombs. From these test results the use of the nose pad appears to produce better results (output) and would be the more practical system to load. In addition it is felt that such a system would reduce or prevent premature activation of HE loaded projectiles when striking armor plate... 

Much of the discussion thus far has been concerned with binary solutions. Most practical systems, however, are more complex and consist of several components. It is now in order to examine the thermodynamics of solutions which contain several dilute solutes. The activity of B in dilute solution with respect to the Henrian standard state is given by... 

The activation and transformation of C-H bonds in alkanes by homogeneous transition metal catalysts should to be a topic of further research. No processes are close to commercialization on a technical scale. So far the organometallic approach by Shilov is one of the most promising ways of producing a practical system [55]. 

The wideband holographic imaging technique is very sensitive because of the active, coherent, heterodyne detection that is employed in typical systems [15-17], Therefore, the primary limitation on image acquisition is the time required to mechanically scan the transceiver. Two-dimensional raster scans are often used for laboratory experiments, and these typically require scan times on the order of 1-30 min. Practical systems employing linear switched antenna arrays and mechanical scanning reduce this time to 1-10 seconds [15-17],... 

The interest in the use of methanol in fuel cell has re-activated fundamental and applied research in the last decade. Approaching the conditions for practical systems, Hamnett and coworkers have obtained FTIR spectra during the adsorption of methanol on finely divided Pt catalysts deposited on graphite [96]. These authors suggest that the activity of the fine-particle catalyst toward the dehydrogenation of methanol is enhanced. Correspondingly, spectra obtained using this catalyst show the formation of adsorbed carbon monoxide at potentials as low as 50 mV vs. RHE.
