Blast pressure gages, heat flux transducers, and sound level meters are to be located at the probable head location of the operator and at representative positions where transient personnel may be located. 

Deluge protection can be applied over the entire hazard area with open sprinkler heads located at various floor levels or fixed water spray systems can be applied specifically on the equipment to be protected. Specific water spray application is preferred because it provides better equipment cooling and reduces the water wasted due to wind and fire draft.

Upflow saturators use a bed of undissolved sodium fluoride as a bed in which water is forced through upward. Water under pressure is distributed through a spider-type distributor head located at the bottom of the tank. This head contains hundreds of tiny slits in which water is forced under pressure through these slits and flows upward through the sodium fluoride bed at a controlled rate to ensure the desired 18,000 ppm of fluoride solution. An upflow saturator requires water pressure at a minimum of 20 psi to a maximum of 100 psi, and the flow into the saturator is regulated at 2 gpm. Because the introduction of water to the bottom of the saturator constitutes a definite cross-connection, a certified backflow preventer must be installed on the water supply line to the saturator along with anti-siphon valve on the solution feed pump (2).

The nature of an oriented film of monomolecular thickness can be typically exemplified by the properties and behavior of stearic acid, one of the most thoroughly studied film-forming substances. Stearic acid (n-octadecanoic acid) in extended, rigid form has the molecular configuration seen in Fig. 10-1. The total chain length is 2.442 nm (24.42 8) and the cross-sectional area is 18.4 x 10 cm (16.4 82). A regularly packed array of these molecules, with their hydrocarbon chains adlineated and their carboxylic heads located as shown in Fig. 10-1, constitutes an oriented film of monomolecular thickness. The physical evidence for the existence and the nature of such films is well known and is described in the standard texts on the chemistry and physics of surfaces [6]. 

For a completely accurate crystal structure determination. X-ray scattering must be observed and recorded by reflection from the vast majority of hfcHattice planes associated with a given biological macromolecule crystal. That is to say that an accurate structural determination is only possible if the vast majority of reciprocal lattice points can be sampled. In order to achieve this, the classical approach has been to use a device like a four-circle diffractometer (Figure 6.15) in which biological macromolecule crystals are first mounted in a goniometer head located at the centre of the diffractometer and then irradiated with an intense beam of X-rays, after which X-ray reflections may be observed sequentially, one at a time, in... 

Other than in the early stage of heating and regardless of the rock-mass properties or failure criteria used, the anchor displacements relative to the MPBX assembly head, located at the collar of the heated drift, were larger for the anchors located farther away from the heated drift. This displacement pattern indicated that the neighboring anchors of an MPBX continued to move away from each other as heating proceeded, suggesting an expansion of the rock mass between the two anchors. This behavior was not strictly observed in the... 

The well pad provides a ground seal around the casing. The pad is constructed of reinforced concrete 6 x 6 ft (6 inches thick) with the well head located in the middle. The well pad prevents contaminants from collecting around the well and seeping down into the ground along the casing.
