It is a pleasure to acknowledge the help of Dr. G. W. A. Milne in searching the literature for compounds related to those under discussion in this paper using the Structure And Nomenclature Substructure Search (SANSS) component of the NIH-EPA Chemical Information System (29). Important communications with Drs. J.-P. Anselme, S. S. Hecht, G. R. Krow, R. N. Loeppky, S. S. Mirvish, and S. R. Tannenbaum are also gratefully acknowledged. 

In conclusions, the nomenclature used for tetrapyrroles and corrinoids that will be used in this paper is based on the species with the highest degree of unsaturation. 

The chemical and physical properties of many of the /2-diketonate and ketoiminate complexes found in the literature are presented in Table V, and a summary of the abbreviations of the /3-diketones and ketoimines used in the literature and in this paper is given in Table VI. The reader should be aware that the original authors nomenclature is used in Table V e. g., Ca(dpm)2, Ba4(tmhd)8, and Ba2(thd)4(N H3)2 are all compounds that contain the same /3-diketonate (2,2,6,6-tetramethylheptane-3,5-dionate). This may seem confusing at first. However, since there is no consensus on the acronyms to use for these ligands, one is liable to come across all the permutations listed in Table VI in the literature, and it seems appropriate to introduce them here. Since many methods have been used to prepare the... 

Peripheral processors which are capable of performing floating point arithmetic operations at high speed are used to enhance the poor performance of popular general purpose minicomputers in this area. These devices are described in various ways but the following nomenclature will be used in this paper. 

The nomenclature used for the lunar samples in this paper is that of NASA. The first two digits (or, as from Apollo 16, the first digit) of the sample number refer to the flight number and hence to the landing site (see Fig. 1) ... 

The purpose of this paper is to describe flie policies and procedures of dietary exposure analysis and risk assessment in these two portions of die world, to highlight their differences, and to demonstrate how they both aim for the same goal, a safe food supply. Unless otherwise noted, all references to exposure in this paper pertain to the intake of pesticide residues in food. Nomenclature in other parts of the world refers to dietary intake, but the general concept is the same, regardless of the terminology. Likewise, all references to risk and risk assessment pertain to the risk assessment with regard to dietary exposure to pesticide residues. 

The new compounds described in this paper have a rhenium atom incorporated into closo-l,2-dicarba-3-rhenadodecaborane or c/oro-l-carba-2-rhenadodecaboranc structures. However, to avoid a complicated nomenclature for the complexes reported, and to relate them to the many known rhenium species with 77-co-ordinated cyclopentadienyl ligands, we treat the cages as nido- 1 -vertex ligands with numbering as for an icosahedron from which the twelfth vertex has been removed. 

In this review carbon blacks are referred to by their industry type designations. For the reader unfamiliar with this nomenclature a brief compilation of the principal characteristics of the carbon blacks mentioned in this paper is given below. More complete listings are available elsewhere 175,239). 

The hippocampal region comprises area dentata, hippocampus, subiculum, presubiculum, area retrosplenialis, parasubiculum and area entorhinalis. In this paper only the two former parts are dealt with. For nomenclature see Blackstad (1956). 

At present, the most suitable nomenclature is one which specifies the treatment applied to a starting material—e.g., dehydrated, Ca-exchanged Type Y zeolite. For brevity in this paper, terms such as La-Y have been used such brevity should cause no confusion since La-exchanged Type Y zeolite is automatically implied. Readers are urged to read the earlier literature carefully since the term faujasite has sometimes been casually applied to Type Y zeolite. 

In this paper protons are referred to with the symbol H, followed by the framework oxygen numbers of the Bronsted hydroxyls, which are numbered according to the sequence commonly adopted. As concerns extraframework cations, they are referred to with Roman numbers the nomenclature commonly adopted in literature to indicate cation sites is followed whenever it is possible, and the nomenclature used by Mortier [18] in his compilation of extrafimnework sites is moreover reported every time this is useful or possible. 

The standard nomenclature for histamine is 1 //-imidazole4(5)-ethanamine. Nevertheless, (2-aminoethyl)-imidazole and /3-(4-imidazolyl)ethylamine are also used in the biological and theoretical studies. In this paper and in all tautomers/ conformers, the ethylamine group is always in position 5 in the imidazolyl group. 

Nomenclature used in this paper DBF represents dibenzofuran, BF represents benzofuran, Y(A) represents a cyclic structure (e.g. Y(C5) is cyclopentadiene), and D is a double bond (e.g. CDO is CH2=0). A represents a radical site on the structure e.g., Y(C5 ) is cyclopentadienyl. In some abbreviated nomenclature the double bond symbol (= or D) is omitted in the name, e g. 0=CHCH=CHCH=CHC =0 is named ODC6 DO. 

Photo system I (PS I) preparations from barley contain polypeptides with apparent molecular masses of 82 (PSI-A and PSI-B), 18 (PSI-D), 16 (PSI-E), 14, 9.5 (PSI-H), 9 (PSI-C), 4, and 1.5 kDa (PSI-I) as determined by sodium dodecyl sulfate polyacrylamide gel electrophoresis (1, 2). The nomenclature used for the subunits is described in more detail by Moller et al. (3). In this paper we report the characterization of a cDNA clone for the PsaE gene encoding the 16-kDa polypeptide PSI-E. The molecular mass of the mature polypeptide is 10,821 Da when deduced from the nucleotide sequence. To test whether the discrepancy between the molecular mass determinations could be due to post-translational modification of the polypeptide, the isolated polypeptide was analyzed by plasma desorption mass spectrometry. It has previously been established that the N- and C-terminal amino acid residues of the PSI-E polypeptide are not modified (4). 

Vice versa, it is of course possible to determine the r parameters from a given experimental sequence length distribution and the initial monomer composition. This is achieved in this paper by only identifying the monomer sequences, (e.g., triads), in the NMR spectrum and using only the intensities of the signals from the comonomer units. For example, for an ethene / 1-hexene copolymer, the evaluation of the pp and ps peaks intensities to determine rj, and the evaluation of the CH-peaks intensities to determine r2 is shown below, scheme (3) (for NMR nomenclature see ref. (7), and for the different sequences see Table (D).
