Relevant specialized periodicals can be found in general university libraries or departmental libraries. Good departments to check are psychology, sociology, criminology, and public policy. Medical and legal libraries are also a possibility, although such materials may be too technical or specialized for most researchers. Some example periodical titles include ... 

Use a terminal period only if the last word of the periodical title is abbreviated. 

Chemical Abstracts periodical title abbreviations are based on the following mles (5). In general, the normal word order of the title is preserved. 

Currently the American Standards Association Sectional Committee Z39 on Library Work and Documentation, Subcommittee on Abbreviations for Periodicals, is working on a standard which will serve as a guide for abbreviating periodical titles. In 1954 the International Standards Organization issued the first edition of ISO Recommendation R4, International Code for the Abbreviation of Titles of Periodicals. This standard was rejected by the American Standards Association on the basis that the general principles established by it were too broad and would lead to varying interpretations and would not achieve the standardization desired. Since ISO R4 became an international standard it has been the subject of several changes or amendments which have been proposed at the ISO Technical Com-... 

Finally, two publications already mentioned, Letopis ZhurnaVnykh Statei and Knizhnaya Letopis even though they are of less use in subject searching, are paramount in importance when searching for book and periodical titles. Knizhnaya Letopis also indexes dissertations for advanced degrees. 

Titles of periodicals are defined as in the Chemical Abstracts Service Source Index (CASSI), except that full stops have been omitted after each abbreviated word. Abbreviations of words in the texts of Chapters 4, 5 and 6 are those in common use and are self evident, e.g. distn, filtd, cone and vac are used for distillation, filtered, concentrated and vacuum. 

Abbreviations of titles of periodicals are defined as in the Chemical Abstracts Service Source Index (CASSI). Other abbreviations are self evident (see Chapter 1, p. 30). 

Title IV represents legislation designed to reduce total SO2 emissions by approximately 50% over a 10-year period. Provisions of the title are designed... 

As indicated by the title, these processes are largely due to the work of Ziegler and coworkers. The type of polymerisation involved is sometimes referred to as co-ordination polymerisation since the mechanism involves a catalyst-monomer co-ordination complex or some other directing force that controls the way in which the monomer approaches the growing chain. The co-ordination catalysts are generally formed by the interaction of the alkyls of Groups I-III metals with halides and other derivatives of transition metals in Groups IV-VIII of the Periodic Table. In a typical process the catalyst is prepared from titanium tetrachloride and aluminium triethyl or some related material. 

The Pharmacology of the Opium Alkaloids, by Krueger, Eddy and Sumwalt, which covers the period 1800 to 1942, and gives a comprehensive survey of pharmacological observations on the alkaloids of opium and their derivatives, with an exhaustive bibliography of over 10,000 titles. 

The reader should note that tlie introductory comments in tine similarly titled subsections of the previous section applies to carcinogens as well. The calculation proceeds as follows. First, smn tlie cancer risks for each exposure patliway contributing to exposure of the same individual or subpopulation. For Superfimd risk assessments, cancer risks from various exposure patliways are assumed to be additive, as long as tlie risks are for tlie same individuals and time period (i.e., less-tlian-lifetime e.xposures have all been converted to equivalent lifetime exposures). Tliis smnmation procedure is described below ...

Preparation of Intermediate Compound 2-Methyl-3-o-Tolyl-6-Sulfamyl-7-Chloro-4(3H)-Quinazoiinone Set up a 5-liter 3-necked flask fitted with a stirrer, condenser and a drying tube. To a stirred mixture of 100 g (0.342 mol) of powdered 4-chloro-5-sulfamyl-N-acetylanthranilic acid, 40.2 g (0.376 mol) of o-toluidine and 2.0 liters of dry toluene was added dropwise, over a period of 15 minutes, 21.7 ml (34.1 g) (0.248 mol) of phosphorus trichloride. The mixture was then refluxed for 10 hours. The solid turned somewhat gummy towards the latter part of the first hour. The mixture then became more free flowing as heating was continued. Let stand overnight. The yellow solid was filtered, washed with toluene and dried. The toluene filtrate was discarded. The dried solid was triturated with 1.5 liters of 10% sodium bicarbonate, filtered and the cake washed with water. The filtrate on acidification yielded 11.5 g of the starting acid. The damp product was dissolved in 4,5 liters of 95% ethanol and the solution treated with charcoal and filtered. On cooling filtrate yielded 69.5 g (55.5%) of the title compound, MP 271.5° to 274°C. 

Professor of Physics Applied to Natural History was created for his father at the Museum d Histoire Naturelle, Edmund had the dilemma of choosing to attend TEcole Normale, I Ecole Polytechnique, or become an assistant to his father for the course that went with the professorship. He chose to assist his fatlier, and their collaboration continued for decades. Thus, his title on the title page of the hook published in 1855-1856 with his father is given as Professeur all Cousei vatoire imperial des Ai ts et Metiers, Aide-naturaliste au Museum d Histoire Naturelle, etc. After a short period as assistant at la. Sorhonne, and then as Professor at the Institut Agronomique de Versailles, he became Professor at the Cousei vatoire des Ai ts et Metiers in 1852, where he worked for almost forty years. When his father died in 1878, Edmond succeeded him as director of the Museum in addition to his professorship. He received a degree as Doctor of Science from the University of Paris in 1840, and was elected a member of I Academie des Sciences in 1863. 

A mixture of 2,3.7,8.12,13.17.18-octaethylporphyrin (1. M = H2 500 mg. 0.94 mmol), anhyd K2CO, (3.8 g. 27 mmol) and freshly distilled 3-methylpyridine (25 inL) was refluxed under N2 and a solution of p-lol-uenesulfonylhydrazide (5.0 g. 27 mmol) in 3-mcthylpyridine (15 mL) was added dropwise over a period of 2.5 h. The mixture was refluxed for a further 2 h, cooled and extracted with benzene, which was washed with cold dil HC1 and extracted with 85% H3P04 (3 x 35 mL). The combined aqueous extracts were diluted to 60 % H3P04 (by addition of 40 mL of H20) and extracted with benzene. The benzene extracts were then washed with 60% H2P04 and H20 and evaporated to dryness. Crystallization (CHCI, /MeOH) gave the title compound yield 56 mg (11 %). 

As suggested in the title of the present article, we believe that the periodic table, which initially arose from the discovery of atomic weight triads, can now be further enhanced by recognizing the fundamental importance of atomic number triads. In addition one should recognize the more fundamental nature of the elements as basic substances rather than as simple substances, and that the periodic system is primarily a classification of the former. Whereas we previously suggested that these aims were best served by the left-step table we now favor the revised left-step table shown in Figure 3. 

To a solution of 5.1 g (20 mmol) 6-(l-methyl-2-nitroethyl)-l-(4-morpholinyl)-l-cyclohexene in 10 mL of ethanol are added, with cooling, 50 mL of 10% aq hydrochloric acid. The mixture is stood at r.t. for 12 h, the solvent is removed under reduced pressure and the residue is extracted with diethyl ether. The ethereal extract is evaporated leaving the crude title compound as a brown oil yield 3.0 g (80%) which is purified by distillation pale yellow oil, bp 128- 130°C/0.8 Torr nji,5 1.4808. The product is unstable and darkens after a short period of storage. 

However, if one lacks access to these, one may consult Chemical Titles and the keyword index (p. 1611) at the end of each issue of CA. In these cases, of course, it is necessary to know what name might be used for the compound. The name is not necessary for Index Chemicus (p. 1622) one consults the formula indexes. However, these methods are far from complete. Index Chemicus lists primarily new compounds, those which would not have been found in the earlier search. As for chemical Titles, the compound can be found only if it is mentioned in the title. The keyword indexes in CA are more complete, being based on internal subject matter as well as title, but they are by no means exhaustive. Furthermore, all three of these publications lag some distance behind the original journals. To locate all references to a compound after the period covered by the latest semiannual formula index of CA, it is necessary to use CAS-online. 

Most headings are sentence-fragment phrases which constitute sentences when combined. Usually a period signifies the end of a combined sentence. In order to reconstitute the context in which a heading is to be read, superior-rank titles are printed as running heads on each page. When the sentences are put together from their constituent parts, they describe the contents of the piece at hand. For an example, see 2.3 below.
