Method of presentation

Adsorption Plots. Isotherm plots are the most common method of presenting adsorption data. An isotherm is a curve of constant temperature the adsorbed water content of the adsorbent is plotted against the water partial pressure in equiHbrium with the adsorbent. An isostere plot shows curves of constant adsorbed water content the vapor pressure in equiHbrium with the adsorbent is plotted against temperature. Figure 13 shows isosteres for the three primary adsorbents described previously. In this case, the dew points for the three adsorbents are plotted at 0.5, 5, and 10 kg... 

The more usual method of presenting data on the corrosiveness of various chemicals is by reference to a specific class of metal or material. Thus in the present book, the sections devoted to individual classes of materials contains lists of chemicals and in some cases details of their behaviour under various conditions of concentration, flow and temperature (see in particular the sections devoted to metals and alloys). 

Both compd types are listed under Nitroimines by Beil and are so presented here. Perhaps this method of presentation is because of the lack of a nitrimine structural definition... 

This method of presenting the topic of blast damage mechanisms was chosen primarily because it highlights the relationships between blast wave properties and structural response or damage. But, we hope that you now also know that the P-i or isodamage curves for structures can be useful design tools. 

There are several useful websites that deal with the various topics of geometry. Visit these sites if you feel you need further clarification on these concepts. Each one has a unique method of presentation. 

Another feature of this book is the extensive use of subheadings in outline form to indicate the position of a given topic in the general sequence of presentation. In using this method of presentation, we have been influenced strongly by the viewpoint expressed so aptly by Poincare ... 

Cost-capacity plots of equipment indicate a straight-line relationship on a log-log plot. Figure 9-4 is an example of such a plot. A convenient method of presenting these data is in equation format ... 

In most instances the average is defined on a weight basis, but in some instances a number basis is employed and this can cause a considerable change in the average value. The most meaningful method of presentation will depend on the end application. 

Our purpose has been to provide a comprehensive survey of the properties of a conceptual framework within which it is possible to interpret the properties of a variety of radiationless processes. It is pertinent to remark that we do not review the important work of Mies and Kraus,13 although we do refer to it often. The method of presentation chosen by us emphasizes our point of view and the techniques we have used. It is for this reason alone that the work of Mies and Kraus is not extensively displayed. 

There are many applications of the pattern method of presentation of water-analysis data. Figure 16-3 shows the correlation of the Arbuckle formation through four Kansas counties by comparisons of the patterns of the water from four fields completed in the Arbuckle. Other uses include determination of the source of contamination of fresh water, confirmation of the zone in which a new well is to be completed, and detection of incursion of foreign water into an existing well due to improper cementing of casing or leaks in the casing. 

The concentrations are volume or mole percent or parts-per-mill-ion (v/v). This is the usual method of presenting gas concentrations as opposed to those on a weight basis. The container must be thoroughly mixed to ensure homogeneity. The two major sources of error of this technique come from lack of good mixing and not... 

The operator forms an essential link in any total plant instrumentation and control strategy, and the conveying of information to the process plant operator and the speed at which the operator is able to respond are important considerations. Methods of presentation of information (concerning plant status) to the plant operator, manager or engineer are undergoing a considerable evolution and the effectiveness of the presentation of process data is dependent upon the hardware employed to visualise the data and the protocol used to display it. 

Often there will be combinations of these and plants will have some means of visually recording data (e.g. by the use of charts) as well as employing indicators to show immediate readings. Retrofitted (updated) units may contain all four methods of presentation. Newer plant is more likely to employ the video terminal as the principal source of information, although local indicators may well be fixed to pumps, etc. 

The presence of a liquid crystalline phase at high surfactant concentrations has been shown by Shinoda (31), but the method of presentation renders the evaluation of the temperature dependence of necessary emulsifier concentrations to obtain the liquid crystalline phase difficult. Although several phase diagrams of the system (water, emulsifier, and nonionic surfactant) have been published (4, 45, 46, 47, 48), no results have been given on the relation between the surfactant phase and the lamellar liquid crystalline phase in these systems. 

Statistics, the science of description and interpretation of numerical data, began in its most rudimentary form in the census and taxation of ancient Egypt and Babylon. Statistics progressed little beyond this simple tabulation of data until the theoretical developments of the eighteenth and nineteenth centuries. As experimental science developed, the need grew for improved methods of presentation and analysis of numerical data. 

A generalized method of presenting real gas behavior is due to Pitzer et al. [17]. They introduced an acentric factor, co, defined as... 

Whichever method of presentation is chosen, it is critical that the numerical estimates not be separated from the various assumptions upon which they are based and their uncertainties. The dose-response characterization should contain a discussion and interpretation of the numerical estimates so that the risk manager gains significant insight into the extent to which the quantitative estimate reflects the true magnitude of potential human responses. The risk manager needs to understand that the true human health risk cannot be known with the degree of accuracy reflected in the numerical estimates.
