Availability and Sources of Information

Jenks PJ and Klich H (2001) Availability and sources of information. In Stoeppler M, Wolf WR and Jenks PJ, eds. Reference materials for chemical analysis - certification, availability and proper usage, pp. 256-278. Wiley-VCH, Weinheim. 

Integrated Systems. Until recently, each of the numerous databases and sources of information available to chemists and technologists had to be searched iadividually, and selected results either ptinted for file storage or downloaded to an ia-house or private computer system for easy future access. 

Although MEPAS applications are often data intensive, the MEPAS documentation provides both application guidance (5) and definitions and sources of information for all input parameters (6). When available, site-specific data are used. Alternative procedures are provided for estimating emission, transport, and exposure parameter values for sites using local, regional, state, and federal information sources. 

Many professional societies take an interest in workplace safety and are available as sources of information. A list of some of these organizations follows. 

Gathering, using and giving information relating to safety is critical to successful safety management. In this section we will review the nature and sources of information available, which will not only assist in providing information for this programme but will also provide information and a direction for future reference. 

Table 12.5 Examples of the type and sources of information available for an investigation...

This presentation will not attempt to present all these projects, but instead focus on the ongoing network activities and the available sources for further information through the Commission s information services, with the CORDIS database being the prime source of information (see details at the end of the paper). 

A good source of information regarding the scientifre background of ab-initio and semi-empirical calculations are the manuals that accompany commercial software. Some of the documentation is available for evaluation on the Internet,... 

In compiling this book, the author has drawn freely from all sources of information available to him—research notes, original memoirs in scientific journals, reference works on organic chemistry, the numerous text books on practical organic chemistry, and pamphlets of manufac turers of specialised apparatus. Whilst individual acknowledgement cannot obviously be made—in many cases the original source has been lost track of—it is a duty and a pleasure to place on record the debt the writer owes to all these sources. Mention must, however, be made of Organic Syntheses, to which the reader is referred for further details of many of the preparations described in the text. 

There are a number of other sources of information available about the synthesis of indoles. The most comprehensive entree to the older literature is through Volume 25, Parts I-IIl, of The Chemistry of Heterocyclic Compounds, which were published between 1972 and 1979[23]. Work to the early 1980s is reviewed in Comprehensive Heterocyclic Chemistry[24 and a second edition is forthcoming[25]. Other reviews emphasizing recent developments are also availablc[26-28]. 

ISI is available in hard copy and electronically at EPA s headquarters and regional Hbraries, and through the National Technical Information Service (NTIS). The electronic form may be installed on IBM PC-compatible computers or placed on local area networks, and mn under Microsoft WINDOWS or WordPerfect s Library program. The Macintosh version is no longer available. The 1993 update will include the ISI hardcopy, PC disks, and the PC system user manual. EPA also pubHshes ACCESS EPA, which provides sources of information, databases, and pubHcations within the EPA. Chapter 5 of that pubhcation includes important environmental databases in air and soHd waste, pesticides and toxic substances, water, and cross-program (110). EPA also provides databases accessible through EPA Hbraries, which describe the private EPA and commercial databases available to Hbrary users (111). 

No coherent threadline could be maintained and the extmdate flew off the windup as short, brittle, crystalline lengths. Not until many years later did other workers show that this polymer on cooling exhibits a mesophase transition directly from the isotropic melt to a smectic A phase. Good sources of information on Hquid crystals and Hquid crystal polymers are available (212—216). 

Most tanks store Hquid rather than gases or soHds. Characteristics and properties such as corrosiveness, internal pressures of multicomponent solutions, tendency to scale or sublime, and formation of deposits and sludges are vital for the tank designer and the operator of the tank and are discussed herein. Excluded from the discussion are the unique properties and hazards of aerosols (qv), unstable Hquids, and emulsions (qv). A good source of information for Hquid properties for a wide range of compounds is available (2). 

Several periodicals devoted to ultrapurification and separations have been started. These include "Progress in Separation and Purification" Ed. (vol. 1) E.S. Perry, Wiley-lnterscience, New York, vols. 1-4, 1968-1971, and Separation and Purification Methods Ed. E.S.Perry and C.J.van Oss, Marcel Dekker, New York, vol. 1-, 1973-. Nevertheless, there still remains a broad area in which a general improvement in the level of purity of many compounds can be achieved by applying more or less conventional procedures. The need for a convenient source of information on methods of purifying available laboratory chemicals was indicated by the continuing demand for copies of this book even though it had been out of print for several years. 

Water Quality and Treatment Handbook, 5th Edition - State-of-the-art handbook of community water supplies The leading source of information on water quality, water Ueatment, and quality control for 60 years is now available in an up-to-the-minute new edition. Go to this site for detailed contents of this important publication. http //preview.mcgraw-hill.com/info/com. 

Many of the sites did not effectively identify the nature and location of potential emergencies. The contractors SSAHPs at Sites A, B, F, and K did not include site-specific information about the nature and source of potential emergencies. The plan in effect at Site H did not provide a description of the nature and location of potential spill hazards and emergencies, nor did it indicate the type of spill containment equipment available or the locations on site where this and other emergency response equipment was stored. 

The amount of worldwide energy reserves and life is variable according to the source of information used, but the position is of the order shown in Table 30.1. Thus at some time in the not too distant future (less than 100 years) oil, gas and uranium will no longer be available. Every effort is required to reduce the world s... 

As planned maintenance encompasses all types covered within the preventive or scheduled systems, this can be examined in more detail. In preparing a planned maintenance system, all the available sources of information should be used. These include manufacturers and suppliers literature, trade associations, professional institutions, knowledge and experience from within the department and history and feedback from previous work for the specific type of equipment. 

For an inquiring mind (which is an essential tool in the field of maintenance), sources of information outside the service department are available and include manufacturers, suppliers, trade associations, engineering institutions (e.g. plant, mechanical, electrical, etc.), consultants, and suppliers of maintenance systems, libraries, and technical journals and the Internet.
