Data types nominal

Although this appendix is nominally about books, we also included proceedings of meetings even if they were published in a special issue of a journal. Some, but definitely not all, special thematic issues of journals have been classified as books in CAplus. Generally, the items included were assigned with a data type of book by the CAS staff. CAS has classified a smattering of users manuals for specific pieces of software as books, but we did not include these in our compilations. 

Figure 9. Oxygen isotope compositions of nominally fresh MORE glasses and whole-rocks. Unfilled boxes are data collected using conventional (resistance heated) fluorination methods between 1966 and 1993 filled boxes are data collected only on glass using laser-based methods. Where these two data types overlap, conventional fluorination data are shown as white-outlined boxes. Data sources Taylor (1968), Muehlenbachs and Clayton (1972), Pineau et al. (1976), Kyser et al. (1982), Muehlenbachs and Byerly (1982), Ito et al. (1987), Barrat et al. (1993), Harmon and Hoefs (1995) and references therein, Eiler et al. (2000b), and Eiler and Kitchen (unpublished data).

Product standards comprise main overall dimensions, weights, and electric data on production series or on single parts. Example DIN 43 595, titled Lead-acid accumulators tubular plate-type cells for water- and land-bound vehicles, low maintenance type. Nominal capacities main dimensions. ... 

In order to define an accident database, we have to specify the types of facts or data elements to be included in each accident or near-accident record. We also have to specify a data type for each element. This tells us whether the data is coded according to a nominal, ordinal, interval or ratio scale or stored in free text. Both these specifications are included in the so-called database definition. Each data element and its associated data-type specification are...

The heat transfer data discussed above refer only to the average behavior of a vial of a given type which is surrounded by other vials in a hexagonal packing array of vials. We now consider intervial variations in heat transfer in a set of nominally equivalent vials and variations in heat transfer arising from variations in the position of the vial in the array. An experiment demonstrating such variations is described by Figure 35. Each circle represents a vial placed on a temperature-controlled shelf in a small laboratory freeze dryer. The vials contained pure... 

The factors in Table 3 were selected from a non-aqueous chiral separation method for timolol. One qualitative factor (1), i.e., the type of CE equipment, was examined. Two HPCE systems, A and B, with different software versions for equipment control, data acquisition, and handling were compared. Six quantitative factors ((2) till (7)), for which the extreme levels usually were situated symmetrically around the nominal, also were... 

Fig. 26 Fourier transform spectrum of v2 of ammonia. Trace (a) is a section of the infrared absorption spectrum of ammonia recorded on a Digilab Fourier transform spectrometer at a nominal resolution of 0.125 cm-1. In this section of the spectrum near 848 cm-1 the sidelobes of the sine response function partially cancel, but the spectrum exhibits negative absorption and some sidelobes. Trace (b) is the same section of the ammonia spectrum using triangular apodiza-tion to produce a sine-squared transfer function. Trace (c) is the deconvolution of the sine-squared data using a Jansson-type weight constraint.

The strong points of this technique are its absence of interaction with the stationary phase, rapid dilution and the potential to recover all of the analytes. Because the technique permits the separation of nominal masses ranging from 200 to 107 Da, its main applications are in the analyses of synthetic and natural polymers. The choice of stationary phase for a given separation is made by examination of the calibration curve of various columns. The column of choice is that which provides a linear range over the masses of the compounds found in the sample. The calibration has to be conducted with the same type of polymers because macromolecules can have various forms ranging from pellet-like to thread-like. The data presented in Table 7.1 show the domains of application of the three gels shown in Fig. 7.3, depending on the standards that are used. 

Even when they are nominally the same type and size, packings made by different manufacturers may differ substantially in their pressure drop and mass transfer behavior, so that manufacturers data should be obtained for final design. 

Several electrolytic-conductivity detectors are produced (Table 3.5). The Laboratory Data Control Model 701 Conducto Monitor (Fig.3.59) may be operated in either a differential mode or an absolute mode. It provides direct readout in units of specific conductance and differences as small as 0.01% in the differential mode between the carrier and the carrier plus solute can be measured. The dynamic range of linearity is 0.01-100,000 pSl 1 /cm. The detector can function in solvents ranging from distilled water to concentrated salt solutions without the necessity of changing the cell. The volume of the cell is 2.5 pi, and the nominal cell constant is 20 cm-1. This type of detector is of use mainly in high-speed ion-exchange chromatography for the detection of ionic species.
