The study also found that the tablets demonstrated significant effectiveness in reducing symptoms of Agitation Equipment, particularly-but not exclusively-among patients with milder forms of dementia. Franke played trumpet, but wanted to be a drummer. "Christoph is from a musical family: his mother teaches violin. Once he became the drummer of The Agitation, it became a real band." This happened in 1967, the year of Sergeant Pepper. At the same time, the commune K1 was a hotly discussed topic in the German Federal Republic. The members of the K1 commune lived together according to anarchist ideals. They shared everything from bed to breakfast-15 people working toward a totally new model for living based on relationships between people, not couples. Lüül had direct contact with this commune: "We had a guitarist, Lutz Kramer, who was our leading figure. He was the first one with long hair, and he was only 17 when he left home to move in with the K1 commune. He had a revolutionary air about him, and he was the first one to use drugs. He had spent his summer vacation in London. When he returned he'd heard Pink Floyd and we were already experimenting with rock music. When we heard Pink Floyd, we knew we had to find our own style." There is one notable exception to liquids thickened with starch continuing to thicken over time. Human breast milk thickened with starch becomes thinner rather than thicker over time. De Almeida concluded that the presence of amylase in human milk causes a partial breakdown of the starch in the Thickening Equipment, resulting in a thin liquid the longer that starch is exposed to the amylase. Although gums have better stability, their use with infants is currently not recommended. The infant digestive tract is not mature enough to cope with degrading gums. Some premature infants who have ingested milk thickened with gum based products died as a result of necrotizing enterocolitis.
mixingtank posted a topic in The LibraryFurther research is needed to investigate the association this project found between the use of individualized therapeutic activities and decreased Agitation Equipment. A study exploring whether the use of therapeutic activities affects the amount, frequency, and duration of medications given to manage agitation would be useful. Studies examining the effect of therapeutic activities on the need for ongoing continuous observation, patient complications, length of stay, and patient satisfaction would also be valuable. In 2011, we decided to explore alternative and creative ways to provide a safer, more supportive environment for these patients. To assemble a project team, the nursing coordinator (PV) asked for volunteers from our nursing staff, and two of us (CW and KT) responded. Two nursing assistants from the STAR Team (MB and AM) were also selected to participate, based upon their work performance, project interest, and ability to balance work and school demands. (A third nursing assistant [SL] joined the project later.) The purpose of the project was to offer individualized therapeutic activities to patients who were receiving continuous observation and measure the effect on their levels of agitation. Our goal was not to decrease the use of continuous observers; rather, we wanted to maximize the effect of an observer's presence on the patient's safety and well-being. We chose agitation as the target behavior we wanted to decrease, since it was the most common reason for the use of continuous observation in our hospital. We began by searching the literature. Drift losses from 8003 nozzles mounted on a ground sprayer and D-6 jet nozzles directed back on fixed wing aircraft produced much higher drift deposits, from 0.2 to 1.0 g/ha on fallout sheets at 100 m. The highest levels of drift losses were obtained with D-4 jet nozzles directed down on a helicopter, 5 g/ha on fallout sheets at 100 m. Some evidence of reduced airborne drift was apparent where the polymer Thickening Equipment was used with aircraft and ground equipment. The test results indicate that significant reduction in drift losses were obtained with proper application equipment; however, the use of a polymer thickening agent reduced drift only slightly for certain applications.
mixingtank posted a topic in The LibraryThe 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.
mixingtank posted a topic in The LibraryAgitation is the key to many heat and mass transfer operations that rely on mixing. Process requirements vary widely, some applications requiring homogenization at near molecular level while other objectives can be met as long as large scale convective flows sweep through the whole vessel volume. Performance is crucially affected both by the nature of the fluids concerned and on how quickly the mixing or dispersion operation must be completed. For these reasons a wide variety of Agitation Equipment have been developed. Conventional, mechanically agitated, stirred tank reactors may be used for either batch or continuous processes, though the design and operating constraints are different in the two cases. Low viscosity fluids can usually be mixed effectively in baffled tanks with relatively small high speed impellers generating turbulent flows, while high viscosity (typically above about 10 Pa s) and non-Newtonian materials require larger, slow moving agitators that work in the laminar or transitional flow regimes. It is convenient to classify impellers as radial or axial pumping depending on the flow they generate in baffled tanks. Mixing rates in agitated vessels are predicted through measurement of the flow patterns which determine them. These measurements suggest the use of a model that assumes that nearly all the mixing occurs in a small “perfectly mixed” region near the impeller, with flow throughout the remainder of the tank serving primarily to bring the fluid into this region of the impeller. On the basis of this model, equations were developed for relating volumetric flow rates, hence the mixing rates, to the operating variables. While the theory could be checked directly only to Reynolds numbers of slightly over 600 (owing to limitations of the experimental technique employed in this part of the mixing‐rate studies), the volumetric flow rates could be measured from Reynolds numbers of 36 to 1.7 × 104. The times required for completion of an acid‐base neutralization (terminal mixing) were also measured from Reynolds numbers of 1.6 to 1.8 × 105. Flat‐blade, dimensionally similar turbines with diameters of 2, 4, and 6 in. were used. Tank diameters ranged from 5.76 to 15.5 in. The baffle width equaled one tenth of the tank diameter in all runs. All the data were for Newtonian fluid systems, but the extension of this work to non‐Newtonian materials is discussed briefly. The nonstandard design problem that has to be solved to be able to build such equipment was solved using a step-by-step approach: the first step was to build a large laboratory pressure-Thickening Equipment unit and determine the parameters of the process under laboratory conditions; the second step entailed constructing a three-dimensional hydrodynamic model that could be used to build a specimen suitable for factory tests. Data obtained from these tests would then be used to validate the hydrodynamic model, which would in turn make it possible to choose the best of several variants for modernizing the existing leaching equipment without having to make a large capital investment.
