The intervention appeared effective in reducing levels of Agitation Equipment

Recommended Posts

The intervention appeared effective in reducing levels of Agitation Equipment in selected patients who were receiving continuous observation on nonpsychiatric units at a large, urban level 1 trauma center. Many patients expressed gratitude for the diversion from their health issues. Further investigation into the effectiveness of this intervention and its impact on the use of medications or restraints is warranted.

A production mixing unit is usually not geometrically similar to the mixer used for process development. Such differences can make scale-up from the laboratory or pilot plant challenging. A solution to these problems is to systematically calculate and evaluate mixing characteristics for each geometry change. Geometric similarity is often used in mixing scale-up because it greatly simplifies design calculations. Geometric similarity means that a single ratio between small scale and large scale applies to every length dimension. With geometric similarity, all of the length dimensions in the large-scale equipment are set by the corresponding dimensions in the small-scale equipment. The only remaining variable for scale-up to large-scale mixing is the rotational speed-one or more mixing characteristics, such as tip speed, can be duplicated by the appropriate selection of a large-scale mixer speed.

In the production of paper, the ground fibrous mass is mixed with water, thereby forming a suspension. After stirring and the removal of mechanical impurities, the suspension is subjected to Thickening Equipment prior to shipment to the factory. In wet concentration of ores, a pulp is formed, which consists of a concentrate and 40–60 percent water. Since the water content in the concentrate shipped to the factory should not exceed 5–15 percent, the pulp is first thickened, which reduces the water content by a factor of 1.5–2, and then dehydrated, which results in an almost total removal of water. When dredges are used to work gravel deposits containing sand, the content of the material in the pulp is 3–6 percent by volume.
