Flow charting results

Flow charts may be developed through interviews or by assembling a group familiar with the existing processes. A facilitator helps the team identify all the process steps and builds up a representation of the overall process on a board using removable sticky notes. The resulting flow chart, Exhibit 3-5, has a more familiar look than that in Exhibit 3-4. 

Laboratory applications of the computer, as evidenced by this symposium, are concentrating more on the result, and less on the hardware required to accomplish that result. A few years ago, a symposium of this type would have concentrated on the automated collection and analysis of data from laboratory instrumentation. Each paper would read like a chapter from "Tom Swift and His Electric Lab Whiz" and would dwell on the details of circuit diagrams and program flow charts. These papers were presented by... 

Details of the specific types of apparatus need not normally be given except for nonstandard processes. A flow chart of the manufacturing operation and the in-process controls (and acceptance limits) is required. Proposals for alternative processes will need to be supported by appropriate data to show that the finished products resulting from these are consistent with the finished product specification. Certain manufacturing operations such as mixing may require additional information on quality parameters monitored during production and prior to batch release. Appropriate quality parameters should be included in the finished product specification regardless of the outcome of validation studies (e.g., content uniformity for solid and semi-solid products). 

Use of multivariate approaches based on classification modelling based on cluster analysis, factor analysis and the SIMCA technique [98,99], and the Kohonen artificial neural network [100]. All these methods, though rarely implemented, lead to very good results not achievable with classical strategies (comparisons, amino acid ratios, flow charts) and, moreover it is possible to know the confidence level of the classification carried out. 

Results are entered into the DENV water quality database and a report with the results is sent to the well owner by the New Brunswick Department of Health (NB Health). A flow chart of this process is illustrated in Figure 1. 

A schematic flow chart of the beneficiation options that are currently in practice is shown in Fig. 7. These processing schemes are primarily employed for the production of pozzolan, but other products may result, such as carbon fuel and mineral grade filler. The fly ash beneficiation option applicable to a specific site is dependent on many factors, but the primary consideration is whether the fly ash is wet or dry. Once ash has been wetted, flotation is the only practical beneficiation option. It may be technically feasible to use thermal processes on damp ash, but the amount of heat required will be significantly increased, thus decreasing the economic value... 

The order of procedures that result in the publication of an EHC monograph is shown in the flow chart on the next page. A designated staff member of IPCS, responsible for the scientific quality of the document, serves as Responsible Officer (RO). The IPCS Editor is responsible for layout and language. The first draft, prepared by consultants or, more usually, staff from an IPCS Participating Institution, is based initially on data provided from the International Register of Potentially Toxic Chemicals and from reference databases such as Medline and Toxline. 

Using the criteria discussed above, we wish to select the easiest method of calculation which is both feasible to apply to the molecules of interest, and whose results are sufficiently accurate to describe the relevant experimental results. We have found it convenient to organize this selection process into a flow chart, which is given in Fig. 1. Starting at the top, one makes a sequence of decisions based upon the criteria for feasibility and accuracy. Decisions about the relative ease of different methods are not made explicitly they are implicit in the organization of the flow chart. 

We first follow the flow chart for the simple case of elastic scattering of structureless atoms. The number of internal states, Nc, is one, quantum scattering calculations are feasible and recommended, for even the smallest modem computer. The Numerov method has often been used for such calculations (41), but the recent method based on analytic approximations by Airy functions (2) obtains the same results with many fewer evaluations of the potential function. The WKB approximation also requires a relatively small number of function evaluations, but its accuracy is limited, whereas the piecewise analytic method (2) can obtain results to any preset, desired accuracy. 

An example of an actual physical activation procedure is as follows [176] the dried raw material is crushed, and sieved then the furnace temperature is increased at a rate of 10 [°C/min] up to 600°C for about 3 h, under inert purge gas flow. The resulting chars are then activated at 500°C-900°C for 10-60 min under purified C02 flush. In Figure 3.16 [175], a flow chart of the physical activation method is shown. 

The isomers of butene are but-l-ene (with only a plane of symmetry, symmetry point group Cs), ( )-but-2-ene (with a horizontal plane of symmetry, a twofold axis of symmetry perpendicular to it, and a centre of symmetry, symmetry point group C2h), (Z)-but-2-ene (with a twofold proper axis of symmetry and two planes of symmetry containing this axis, symmetry point group C2V) and isobutene (2-methylpropene) with two mutually perpendicular planes of symmetry and on the line of intersection of these two planes there is a twofold axis of symmetry. The symmetry point group is therefore C2v. These results can be verified using the flow chart in the appendix.
