Checks, definition

Use a thesaurus to find a more precise and appropriate word to fit your meaning, but check definitions of unfamiliar words with a dictionary. 

The text is fully illustrated with original line diagrams. The final chapter is a substantial section of self-assessment material (including structured exercises and multiple choice questions), enabling readers to monitor their own progress. A glossary of terms is provided to help readers to understand the jargon of the subject and to check definitions etc. 

The three-part draft of the radioscopy standard pr EN 13068 is ready for the necessary european inquiries. This standard covers the requirements placed on the imaging system, the checking procedures as to the performance of the entire system and also the specifications of user guidelines for certain inspection tasks. The standard remains open to the definition of new inspection classes for future application cases. 

The state variables define a point on the diagram the "constitution point". If this point is given, then the equilibrium number of phases can be read off. So, too, can their composition and the quantity of each phase - but that comes later. So the diagram tells you the entire constitution of any given alloy, at equilibrium. Refer back to the definition of eonstitution (p. 311) and check that this is so. 

Early in the life of a project, information has not been developed to allow definitive cost estimates based on material takeoff and vendor quotes for equipment. Therefore, it is necessary to estimate the cost of a facility using shortcut methods. The first step is to develop or check flow-sheets, major equipment sizes, and specification sheets as described in earlier chapters. From the equipment specification sheets, the cost of each piece of equipment is estimated, using techniques discussed later. Once the major equipment cost has been estimated, the total battery limit plant cost can he quickly estimated using factors developed on a similar project. 

Indicate whether the chemical is manufactured (including imported), processed, or othen/vise used at the facility and the general nature of such activities and uses at the facility during the calendar year. Report activities that take place only at your facility, not activities that take place at other facilities involving your products. You must check all the blocks in this section that apply, tf you are a manufacturer of the chemical, you must check a and/or b, and at least one of c,.ji. e> orf. Refer to the definitions of manufacture," "process," and othenwise use" in the general information section of these instrilctions or section 372.3 of the rule for additional explanations. 

Note, since different types of machine have different sigma values, always take care in checking the precise definition of S. 

Definition of Responsibilities Facility personnel understand their roles and responsibilities in achieving the desired level of PSM performance. Appropriate checks and balances have been establish to minimize confiicts of interest. Internai coordination and communication mechanisms exist. 

Next we investigate the physical content of the Dirac equation. To that end we inquire as to the solutions of the Dirac equation corresponding to free particles moving with definite energy and momentum. One easily checks that the Dirac equation admits of plane wave solutions of the form... 

Since the foregoing tests were carried out at -identical conditions of compn and temp, and in a standard test fixture, the burning times serve as a means of checking the relative fineness of thea powdered tungsten fuels. The rapid burning times indicate that both M-10 and M-20 are very fine. Also, the M-10 is definitely finer than M-20, as shown by the difference in burning times... 

Checking the literature of the second half of the 1980s for applications of crown complexes of arenediazonium salts for synthetic purposes, one gets the impression that these complexes are not widely used. The two comprehensive reviews by Izatt et al. (1985, 1991) show a definite decline of interest in host —guest complexation of arenediazonium ions in the second half of the 1980s. The subject of arenediazonium... 

The most appropriate experimental procedure is to treat the metal in UHV, controlling the state of the surface with spectroscopic techniques (low-energy electron diffraction, LEED atomic emission spectroscopy, AES), followed by rapid and protected transfer into the electrochemical cell. This assemblage is definitely appropriate for comparing UHV and electrochemical experiments. However, the effect of the contact with the solution must always be checked, possibly with a backward transfer. These aspects are discussed in further detail for specific metals later on. 

Definition and Uses of Standards. In the context of this paper, the term "standard" denotes a well-characterized material for which a physical parameter or concentration of chemical constituent has been determined with a known precision and accuracy. These standards can be used to check or determine (a) instrumental parameters such as wavelength accuracy, detection-system spectral responsivity, and stability (b) the instrument response to specific fluorescent species and (c) the accuracy of measurements made by specific Instruments or measurement procedures (assess whether the analytical measurement process is in statistical control and whether it exhibits bias). Once the luminescence instrumentation has been calibrated, it can be used to measure the luminescence characteristics of chemical systems, including corrected excitation and emission spectra, quantum yields, decay times, emission anisotropies, energy transfer, and, with appropriate standards, the concentrations of chemical constituents in complex S2unples. 

Check for potential conflicts in the specification of the goal state, and provide resolution for its consistent definition. 

Check of the planarity of functional groups which are by definition planar, e.g., aniline nitrogen, double bonds or amides. 

Much of the early work with certified reference materials was linked to the derivation of reference methods and there was a period in which primary or definitive (i.e. very accurate but usually very complex) and secondary (or usable) methods were reported e.g. steroid hormones (Siekmann 1979), creatinine (Siekmann 1985), urea (Welch et al. 1984) and nickel (Brown et al. 1981). Although there are some application areas, such as checking the concentrations of preparations listed in a pharmacopoeia, where a prescribed, defined method has to be used, in practice such work is limited. However, this approach to chemical analysis is no longer widely used and will not be further discussed. The emphasis now is placed on using RMs to demonstrate that a method in use meets analytical criteria or targets deemed to be appropriate for the application and to develop figures of merit (Delves 1984). 

To make the phase angle plot, we simply use the definition of ZGp(joo). As for the polar (Nyquist) plot, we do a frequency parametric calculation of Gp(jco) and ZGp(joo), or we can simply plot the real part versus the imaginary part of Gptjco).1 To check that a computer program is working properly, we only need to use the high and low frequency asymptotes—the same if we had to do the sketch by hand as in the old days. In the limit of low frequencies,... 

Note particularly that it is liters of solution that is used, not liters of solvent. Chemists often abbreviate the definition to merely moles per liter, but the shortening does not change the way the unit is actually defined. The unit of molarity is molar, symbolized M. Special care must be taken with abbreviations in this chapter. M stands for molar mol for mole(s). (Some authors use M to stand for molarity as well as molar. They may use italics for one and not the other. Check your text and follow its convention.)... 

Since there are 2equivalents of H2S04, they must react with 2equivalents of NaOH. Checking, we see that 2 equivalents of NaOH liberate 2 mol of OH and also react with 2 mol H+, and thus there are 2equivalents by definition also. 

To determine whether sample patterns in a database are similar to one another, the values of each of the n parameters that define the sample must be compared. Because it is not possible to check whether points form clusters by actually looking into the n-dimensional space—unless n is very small— some mathematical procedure is needed to identify clustered points. Points that form clusters are, by definition, close to one another, therefore, provided that we can pin down what we mean by "close to one another," it should be possible to spot mathematically any clusters and identify the points that comprise them.
