Zone design

The distribution of rods and cones is shown in Figure 3b centered about the fovea, the area of the retina that has the highest concentration of cones with essentially no rods and also has the best resolving capabiUty, with a resolution about one minute of arc. The fovea is nominally taken as a 5° zone, with its central 1° zone designated the foveola. There are about 40 R and 20 G cones for each B cone in the eye as a whole, whereas in the fovea there are almost no B cones. A result of this is that color perception depends on the angle of the cone of light received by the eye. The extremely complex chemistry involved in the stimulation of opsin molecules, such as the rhodopsin of the rods, and the neural connections in the retinal pathway are well covered in Reference 21.

The bench where decontamination took place was only a few feet from the thermal unit and was not isolated from exclusion zone activities employees moved freely between their work stations in the exclusion zone and the decontamination bench. In addition, the subcontractor did not conduct monitoring activities to support work zone designations. Neither Site K contractor used warning signs to delineate exclusion zones, as required by their respective health and safety plans. 

At the time of the Site I audit, only two established work zones remained on site an exehision zone eneompassing the waste treatment area and a elean zone eneompassing the remainder of the site. Aeeord-ing to the eontraetor s projeet manager, EPA approved this reduetion in site work zones. As a result of this zone designation, workers exit the exehision zone direetly into a elean zone, removing and disearding PPE in a barrel adjaeent to the operations trailer. 

The occupied zone design load of the exhibition hall is 48 kW, corresponding to 300 persons in the pavilion. The equipment for slides and video will generate another 130 kW, which is expected to move upward in convective flows, causing a high temperature in the upper part of the pavilion.

It can he shown mathematically that an efficient dis-persed-gas unit must have a high gas induction rate, a small-diameter-induced gas bubble, and a relatively large mixing zone Design of the induction nozzle or rotor and of internal baffles is critical to unit efficiency.
