PROCEDURE SUMMARY

Prepare 250 mL of each of three solutions of hydrochloric acid with concentrations varying between 0.2 and 1.0 M. Use a stock solution that is 2.0 M for the preparation. Perform the summary procedure three times, once for each concentration, at room temperature using the form of magnesium of your choice (same form each time). 

Prepare 700 mL of 0.50 M HC1 from the stock solution that is 2.0 M and use this acid for the three tests with the different forms of magnesium. If the magnesium is in ribbon form, fold it in an accordion-like fashion and push it into the nipple of the baby bottle. If the magnesium consists of turnings or powder, you may pour it into the nipple from the weighing paper, but be careful not to spill it into the acid before you are ready. Perform the summary procedure for each form. 

Prepare 800 mL of 0.50 M HC1. Perform the summary procedure with a 200 mL portion of it and the form of magnesium of your choice. Then, heat 250 mL of this solution to 30 to 35 °C on a hot plate. Also heat the water to be used in the bucket to the same temperature on another hot plate. Place the warm water in the bucket. Perform the summary procedure using the warm acid and the same form of magnesium as in your first trial. Measure the temperature of the warm water in the bucket while the experiment is running and report this as the temperature of the test. 

Mizutani and colleagues reported the development of a new method for the analysis of 1-malate. As part of their study they analyzed a series of beverages using both their method and a standard spectrophotometric procedure based on a clinical kit purchased from Boerhinger Scientific. A summary follows of their results (in parts per million).

The procedure of simultaneous extracting-spectrophotometric determination of nitrophenols in wastewater is proposed on the example of the analysis of mixtures of mono-, di-, and trinitrophenols. The procedure consists of extraction concentrating in an acid medium, and sequential back-extractions under various pH. Such procedures give possibility for isolation o-, m-, p-nitrophenols, a-, P-, y-dinitrophenols and trinitrophenol in separate groups. Simultaneous determination is carried out by summary light-absorption of nitrophenol-ions. The error of determination concentrations on maximum contaminant level in natural waters doesn t exceed 10%. The peculiarities of application of the sequential extractions under fixed pH were studied on the example of mixture of simplest phenols (phenol, o-, m-, />-cresols). The procedure of their determination is based on the extraction to carbon tetrachloride, subsequent back-extraction and spectrophotometric measurement of interaction products with diazo-p-nitroaniline.

The SFA, originally developed by Tabor and Winterton [56], and later modified by Israelachvili and coworkers [57,58], is ideally suited for measuring molecular level adhesion and deformations. The SFA, shown schematically in Fig. 8i,ii, has been used extensively to measure forces between a variety of surfaces. The SFA combines a Hookian mechanism for measuring force with an interferometer to measure the distance between surfaces. The experimental surfaces are in the form of thin transparent films, and are mounted on cylindrical glass lenses in the SFA using an appropriate adhesive. SFA has been traditionally employed to measure forces between modified mica surfaces. (For a summary of these measurements, see refs. [59,60].) In recent years, several researchers have developed techniques to measure forces between glassy and semicrystalline polymer films, [61-63] silica [64], and silver surfaees [65,66]. The details on the SFA experimental procedure, and the summary of the SFA measurements may be obtained elsewhere (see refs. [57,58], for example.). 

Chapter 1 provides a summary of important equations for estimating the terminal temperatures in a heat exchanger. Here we formalize a short estimating procedure for a countercurrent flow situation. Assume that a specifier of a heat exchanger has defined a preliminary sizing of the unit. The system requires heat and material balances. 

RMDB is supplemented by microfilmed reports containing failure rates/modes and analyzed data. Reports relating to the theory and procedural techniques to obtain and analyze reliability-maintainability data are cataloged, abstracted, microfilmed and computer listed in the R-M Data Summaries.

These diagrams focus on the temporal or time relationships of operations and they can be used to solve resource allocation problems, to determine whether there is any potential for time stress, and to consider alternative work methods in the execution of a procedure. An example drawn from traditional industrial engineering methods is shown in Figure 4.7. The chart is used to analyze the interaction between people and equipment. As indicated in the summary portion of this chart, there is a high proportion of idle time which would probably indicate the use of alternative procedures in the execution of this task. The chart enables the analyst to see the relationships among the activities of the different components in planning such alternatives. 

Most purification procedures for a particular protein are developed in an empirical manner, the overriding principle being purification of the protein to a homogeneous state with acceptable yield. Table 5.5 presents a summary of a purification scheme for a selected protein. Note that the specific activity of the protein (the enzyme xanthine dehydrogenase) in the immuno-affinity purified fraction (fraction 5) has been increased 152/0.108, or 1407 times the specific activity in the crude extract (fraction 1). Thus, xanthine dehydrogenase in fraction 5 versus fraction 1 is enriched more than 1400-fold by the purification procedure. 

Follow the procedures oudined for bare tube equipment, substituting the characteristics of finned tubes where appropriate. The presentation of Wolverine recommends this technique over previous methods. The methods of reference 16 have proven acceptable in a wide number of petrochemical hydrocarbon systems. Figure 10-150 is an example unit in summary form.

While the overall policy responsibility for health and safety rests with senior managers, all employees within the organization, irrespective of their duties, have some degree of responsibility for carrying out the policy. Where appropriate, nominated persons with specific responsibilities for health and safety should be named with a summary of their responsibilities defined. It follows that there should be a procedure established whereby deputies are available during the nominated person s absences.
