Updating references

The distribution coefficient method, often called the A -value method, was conceived by Wilcox et al. (1941) and finalized by Carson and Katz (1942). The best methane, ethane, and propane charts are from the latter reference. Updated charts are presented for carbon dioxide (Unruh and Katz, 1949), hydrogen sulfide (Noaker and Katz, 1954), nitrogen (Jhaveri and Robinson, 1965), isobutane (Wu et al., 1976), and n-butane (Poettmann, 1984), as well as for a method that is a function of hydrate structure (Mann et al., 1989).

Recently published scientific papers are not usually accessible using MEDLINE or similar systems. To keep up to date, it is necessary either to thumb through the title pages of current issues of the scientific journals or, where these are available, to access journals on-line. Alternatively, the following current awareness titles can be used Current Contents and Reference Update. 

These are published weekly, and they list the titles of almost all biochemical papers published in scientific journals Current Contents is published in paper and diskette versions, and Reference Update as a diskette. In the diskette version, the abstracts of papers can also be viewed, if available. The diskette versions also allow literature searches to be carried out using keywords, combinations of keywords, authors and journal titles in a similar way to MEDLINE searches. 

Applied Biochemistry and Biotechnology is made aval table for abstracting or indexing in Chemical Abstracts, Biological Abstracts. Current Contents. Science Citation Index, EMBASE/Excerpla Medica, Index Medicus. Cambridge Scientific Abstracts, Reference Update, and related compendia. 

The forces are calculated from the positions at the start of a simulation. They are used to advance the positions, and half-advance the velocities or momenta. The new forces/(t+5 t) are calculated, and these are used to complete the momentum update. At the end of the step, positions, momenta, and forces all conveniently refer to the same time point. Moreover, as we shall see shortly there is an interesting theoretical derivation of this version of the algoritlnn. 

GenBank [32] is a text-numeric database of genetic sequences with more than 28 billion bases in 22 million sequences (January, 2003) from genetic research. The collection of all publidy available sequences is annotated with information such as sequence description, source organism, sequence length, or references. The database, estabhshed in 1967, is updated daily and produced by the National Center for Biotechnology Information (USA). 

Interestingly, if the original comparison of the spectrum from the reference compound with stored m/z data for that compound reveals discrepancies, the stored reference data are updated before the computer goes on to acquire data from the unknown compound. In this mode, the computer is not used simply to acquire and manipulate data but is also used to make decisions... 

The effort to clarify and articulate the principles of spectrometry as simply as possible appears to have struck a welcome response among those who use mass spectrometers. The original series was not advertised, but, once it had been discovered outside the Micromass organization, there were inquiries as to how it could be purchased. From the start. Micromass offered the series free in a ring-binder format and later also provided it free on CD ROM and then on the Internet. Updating of the first CD led to over 600 requests for it on the day after its release had been announced on the Internet. Partly because of this response — but mainly because users or potential users frequently like to have a traditional reference book — it was decided to publish the series in this present book form.

Burton and Finar published a comparative table of calculations on pyrazole (29) (70JCS(B)1692). That table, updated with recent references and extended to the pyrazole anion (30) and cation (31), is the present Table 2. 

The increasing ranges of pressure and temperature of interest to technology for an ever-increasing number of substances would necessitate additional tables in this subsection as well as in the subsec tion Thermodynamic Properties. Space restrictions preclude this. Hence, in the present revision, an attempt was made to update the fluid-compressibihty tables for selected fluids and to omit tables for other fluids. The reader is thus referred to the fourth edition for tables on miscellaneous gases at 0°C, acetylene, ammonia, ethane, ethylene, hydrogen-nitrogen mixtures, and methyl chloride. The reader is also... 

Table 9-42 presents information on some cost indices for the United States. Engineering News-Record updates its construction-cost index in March, June, September, and December. The Oil and Gas Journal gives the Nelson-Farrar refinery indices in the first issue of each quarter. The Chemical Engineering plant-cost index and Marshall and Swift equipment-cost index are given in each issue of the pubhcation Chemical Engineering. Derivation of the base values is referred to in the respective publications. 

Arrester Testing and Standards Regulatory and approval agencies and insurers impose acceptance testing requirements, sometimes as part of certification standards. The user may also request testing to demonstrate specific performance needs, just as the manufacturer can help develop standards. These interrelationships have resulted in several new and updated performance test procedures. Listing of an arrester by a testing laboratoiy refers only to performance under a defined set of test conditions. The flame arrester user should develop specific application requirements based on the service involved and the safety and risk criteria adopted. 

Documented procedures are often necessary to ensure consistency and correctness for any type of transaction. This section refers to the overall system of communicating, updating, and approving procedures. The procedures pertinent to the implementation of the quality assurance/improvement process should be compiled in a quality manual, the quality manual should be communicated throughout the organization. 

In the tables of relevant Standards in this book while the latest editions of the standards are provided, it is possible that revised editions have become available. With the advances of technology and/or its application, the updating of standards is a continuous process by different standards organizations. It is therefore advisable that for more authentic references, readers should consult the relevant organizations for the latest version of a standard.
