Martensitic type. Heat-affected zone cracking is likely and may be remedied by employing the normal measures required for the control of hydrogen-induced cracking. 

Dosimetry. Ion current measurements required for absolute dosimetry were performed with a Cary 31 ionization chamber and vibrating reed electrometer. Dry nitrogen was used as filling gas for the chamber, and a W value of 34.9 e.v./ion pair was assumed for H-3 beta rays in N2 (27). Deuterium pressures in each of the reaction mixtures were great enough to ensure that less than 1% of the H-3 beta rays reached the walls of the reaction vessel (7). 

Indicate the safety measures required for this plant bearing in mind the toxic and inflammable materials handled. 

Finally the formula for n (the number of discrete measurements required) for a given uncertainty as equation 73-6. 

If we try to refine the adequacy between the measurement procedures and the practical needs for wastewater quality monitoring, different metrological (analytical) characteristics have to be considered, such as detection limit, reliability and robustness (Table 3). Even if it is very difficult to compare the analytical methods carried out in the laboratory with on-site measurements (with on-line or tests kits), this presentation points out the main features of the measurement required for different needs. These characteristics define the quality of the available information [3], which constitutes one of the major problems that... 

Be familiar with the basic measurements required for the experiments. For example, in a calorimetry experiment you do not measure the change in temperature, you calculate it. You measure the initial and final temperatures.

The measurements required for the present receptor models Include particulate matter composition, size and variability for both source and receptor. Obtaining these data requires attention to field study design and data management, source characterization, and analytical methods. 

This section explores the mathematical basis for the statistical treatment of experimental data. Most measurements required for the completion of the experiments can be made in duplicate, triplicate, or even quadruplicate, but it would be impractical and probably a waste of time and materials to make numerous determinations of the same measurement. Rather, when you perform an experimental measurement in the laboratory, you will collect a small sample of data from the population of infinite values for that measurement. To illustrate, imagine that an infinite number of experimental measurements of the pH of a buffer solution are made, and the results are written on slips of paper and placed in a container. It is not feasible to... 

The method parameters to include in system suitability are based on the analytical technique itself and on the particular requirements of the individual method. Most quantitative analytical techniques will have a reproducibility of measurement requirement for system suitability. Quantitative impurity analyses should have a limit of detection (LOD) or LOQ measurement. This is necessary because response may be instrument-dependent or may change from day to day. Table 7 lists suggested system suitability requirements for chromatographic methods from November 1994 Center for Drug Evaluation and Research (CDER) reviewer guidance [2],...

In addition to the cation used to prepare the polymer, other cations with differing charges, sizes, coordination numbers and/or coordination geometries are used in these selectivity quotient measurements to verify specificity. Measurements are also made using polymers prepared with no metal cation (H or NH4 ) as experimental controls. The measurements required for these studies are made using a pH meter for [H ] and elemental analysis (inductively coupled plasma atomic emission spectrometry (ICP-AES) or inductively coupled plasma mass spectrometry (ICP-MS))for [M"-"]. 

A summary of measures required for an effective safeguards system is presented in Table 11.13. 

Requirements for controls are based on definition of closed or open system. Under these definitions there isno direct correlation between, for example, using a publicphone line and an open system. Compliance with closed versus open standards is determined by how access rights to the data or documents are established and controlled by the owner(s) of this information. A system is defined as closed if access to the system containing the records or data is under the control of person(s) responsible for the content of the records or data in the system. A system is defined as open if access to the system is not under the control of the person(s) responsible for the content of the records therein. For example, dial-in retrieval over a public phone is closed where the records being accessed are under the control of the persons responsible for their content, whereas storage of records on a third party system is open because access to the records themselves is under the control of the third party. Sections 11.10 and 11.30 of the Final Rule list, respectively, the control measures required for establishing a closed or open system. 

African scientists must advocate in the use and implementation of good agricultural and collection practices and growers and producers provide traceability and records for the African production of A. annua. Such records provide a detailed description of the cultivation and collection techniques and measures required for a harvest to meet quality requirements 11). 

The current-time measurements required for a coulometric titration are inherently as accurate as or more accurate than the comparable volume/molarity measurements of a conventional volumetric method, particularly when small quantities of reagent are involved. When the accuracy of a titration is limited by the sensitivity of the end point, the two titration methods have comparable accuracies.

The issue of chemical safety in relation to the jxoblem of carcinogenicity has had a powerful influence upon events. The development of the control measures required for the prevention of industrial cancers can now be taken as a model for the prevention of other diseases caused by chemical exposures. A consideration of the classic studies of bladder canco in the dyestuff and rubber industries can be used to define all the elements that must be put togetho to establish an effective system for the elimination of a serious... 

Despite the simplification afforded by the steady state assumption, the fitting of the experimental data in this case requires the optimization of no less than twenty parameters. The effort required to gather adequate data by conventional methods of experimentation makes a kinetic study of this system less than attractive. Fortunately, a TSR can easily provide the rate measurements required for a reliable fitting of a mechanism of this complexity. 

One of the more critical measurements required for phosphors is determining the spectral distribution of the emission and/or that of excitation, that is- the wavelengths which best excite the phosphor. Such an instrument is called a Spectrofluorimeter and has the general optical design, as shown in 6.7.2., presented on the next page. 

Note It is apparent that the mean ion abundance ratio of the sample blend for the second iteration is different from that obtained from the first iteration even though the same solution was used. This is due to long-term instrumental drift as the measurements for the first and second iterations were carried out several days apart. Such drift is negligible during the five alternating measurements required for each iteration and in any event is compensated for by the alternation of the measurements.
