Given an element with four isotopes, we select one of the masses as the reference (ref). Let us call ii, = NJN f the natural ratio of the isotope i to the reference isotope and r, the ratio...

The dipole moments and structures of the org azides and aliphatic diazo compds were studied by Sidgwick et al (Ref 4). Sheinker Syrkin (Ref 13) made vibrational spectra measurements of org azides and deduced the configuration of azide compds. UV spectra confirmed the observations made on Raman and IR spectra. Heats of combustion and formation of org azides were detd by Murrin Carpenter (Ref 16). Patterson et al (Ref 7) discussed the CA method of naming and indexing org azides. For addnl info and discussion of org azides see the general references (Refs 1,2,3,5,8,10 A 12)...

These applications of ultrasonics constitute only a small portion of the total scope of sonic technology which is presented in specialized references (Refs 9 11). Strictly speaking, the ultrasonic range should begin above 16kHz, the limit of human auditory capacity, but as the limits of only a few applications have been extensively explored, the range of ultrasonics of interest here must be chosen somewhat wider. Moreover, the choice of the human auditory... 

Fig. (7). Hepatoprotective Actions of Soyasaponins I - IV toward in vitro Immunological Liver Injury on Primary cultured Rat Hepatocytes Control (Cont.) is the value of hepatocytes which were not administered the antiserum. Reference (Ref.) value were administered the antiserum and not treated with Soyasaponins I (A), II (B), III (C), IV (D). Significantly different from Ref., effective p <0.01.

The numbers refer to Laboratory Manuals listed in the numbered references (refs. 1-20). 

Attempts were made to bracket the PCB concentrations in oil shipments over time. In analyses that were based solely on chlorine content, oil shipped February 5, 1968 had a PCB content of ca. 3000 ppm. Subsequent shipments decreased rapidly, and oils produced after February 19 had PCB traces only (NI0SH Criteria. . ., p. 4l). PCDF at a/0.5% of total PCB concentration, low bromine levels (/v2% of Cl content), traces of chlorinated naphthalenes, and evidence for other unspecified chlorinated contaminants are also noted in the PCB literature references cited in the NI0SH document containing 302 references (ref. 136). 

In the original reference (Ref.3) the last row was incorrecdy presented (a as well as a were missing). 

Salt bridges (particularly those that employ saturated KC1) also have been widely used in the conversion of polarographic and other potentials from one reference-electrode scale to another. This conversion is commonly made by direct comparison of the two reference (ref) electrodes in the cell... 

The scope of the book is too limited to explain the details how such an organization can be actually achieved. The interested reader is advised to relevant references (ref. 11,12). It has to be said, however, that a hierarchical organization shows its full potential when large numbers of items are to be handled. Under the word large number we understand the collections containing several thousand and more spectra.
