Q11 In a school laboratory, which of the pieces of apparatus listed below has the greatest random uncertainty in a measurement ... 

Distillation Under Reduced Pressure—In addition to the apparatus listed in 6.1, the apparatus for distillation under reduced pressure shall include the following ... 

This table lists values of /3, the cubical coefficient of thermal expansion, taken from Essentials of Quantitative Analysis, by Benedetti-Pichler, and from various other sources. The value of /3 represents the relative increases in volume for a change in temperature of 1°C at temperatures in the vicinity of 25°C, and is equal to 3 a, where a is the linear coefficient of thermal expansion. Data are given for the types of glass from which volumetic apparatus is most commonly made, and also for some other materials which have been or may be used in the fabrication of apparatus employed in analytical work. 

A suitable piece of apparatus is listed in Catalog LP-24, p. 43 (1944), of the Coming Glass Works. 

Enamels. Eight commercial enamels, listed in Table I, were applied by roll coating to panels (25 X 76 cm) of 43 kg, Type MR-TU, No. 25 electrolytic tinplate. These panels were cut into strips (10 X 25 cm) and tested for flexibility before and after irradiation with the General Electric impact apparatus by the reverse impact method. The impactor... 

The subject index provides access to the text by way of methods, techniques, reaction types, apparatus, effects and other phenomena. Also, it lists compound classes such as organotin compounds or rare-earth hydrides which cannot be expressed by the empirical formulas of the compound index. 

Figure 46-1. Diagrammatic representation of the two branches of protein sorting occurring by synthesis on (1) cytosolic and (2) membrane-bound polyribosomes. The mitochondrial proteins listed are encoded by nuclear genes. Some of the signals used in further sorting of these proteins are listed in Table 46-4. (ER, endoplasmic reticulum GA, Golgi apparatus.)...

Stankiewicz and Moulijn extend the definition of process intensification from size reduction of apparatus to dramatic improvements in key features of chemical processing [25]. Substantial decreases in the following process-engineering properties are listed ... 

It is certainly this lack of clarity which leads to the current situation. Flashpoints are usually given without any mention of either the open or closed cup aspects or the make of apparatus. Amongst the thousand or so organic substances listed in Part Two, more than one hundred of them mention oc and cc , which enables comparisons to be made. Nevertheless, a study of the data indicates that the difference between experimental values can reach 56°C for the same substance (for instance, butadiene). It happens quite often that for flashpoints lower values oc than cc values for the same substance are found.The nature of the sources of the level of measurement error in flashpoints can easily be guessed at. 

Most chemical substance manufacturers systematically submit their new substances (or preparations) to tests that enable them to evaluate the decomposition risks. There are many types of apparatus that are used to test the effect of the different physical causes of instability. The most important are the mechanical and thermal sensitivity tests. The methods listed below are simply intended to give an idea of the available experimentel possibilities. 

The most common and diverse approach to cleanup (and extraction of water samples) in pesticide residue analysis is SPE. Over the last 20 years, improvements and diversifications in SPE formats, sorbent types, and apparatus have made SPE a widely used approach for a variety of applications, including the analysis of pesticide residues. SPE cartridges or disks can be likened to low-resolution HPLC columns in that similar stationary and mobile phases are used. A typical particle size in SPE is 40 pm, and the plastic cartridges are generally packed with 0.1-1 g of sorbent in plastic tubes. The choice of reversed-phase, normal-phase, and ion-exchange media in SPE is very diverse, and Table 2 lists some of the more popular SPE applications for the cleanup of pesticides.

The AHC Wilkinson catalyst (Rh(Ph3P)3/PTA/Al203) (AHC-Wilk) was prepared using the general procedure described previously (10,12). The catalyst contained 0.5% Rh which corresponds to a 1 1 Rh PTA ratio and about a 4.5% load of the anchored complex. The hydrogenations were ran using the low pressure apparatus previously described (19) under the conditions listed in the discussion. 

The activity of the bacterial translational apparatus can be studied in cellfree systems programmed, depending upon the particular experimental need and design, with any of the mRNAs shown in Fig. 12.1 and listed in Table 12.1. The amount of synthesized product can be assessed using either a radioactive test or, when translation is directed by 027IFCp(A), an immunological test (see later).
