Information sources Catalogues

When planning new installations, manufacturers catalogues may be the only information source of equipment data, but they rarely indicate the space needed outside the equipment outline. This requires careful consideration from an experienced facility planner to establish realistic space requirements.

In preparing this account of the leather manufacture, much of the information, besides what has been derived from private sources, has been obtained from Doctor Mobpjt S able work on Tanning, Knapp S Technology, So mm art, Dumas, Parnell, Sullivan, the Catalogue of the Irish Industrial Exhibition, and other authorities. 

All major chemical companies, and most teaching establishments, now have a computerised stock-control system which enables information about on-site availability and cost of chemicals to be rapidly obtained. Many companies are now linked to a central database (e.g. Chemquest , Pergabase Inc.), which provides information (via text or graphics) on the world-wide commercial availability (from over fifty chemical catalogues) and on relative costs, etc., of fine chemicals. The hazards in use and disposal of all chemicals (see Section 2.3) may be readily checked from the catalogues of major chemical suppliers and other important sources. 

The references used have been catalogued according to the type of information they contain. Each category has been reviewed to highlight the most useful sources of information. 

A convenient source of information about the commercial availability of some 200,000 chemicals is M. Desing (ed.), Chem Sources—USA, published annually by Chemical Sources International, Clemson, SC 29633 in book format and as a CD-ROM. There is also a Chem Sources—Online search engine see www.chemsources.com. Many suppliers of chemicals maintain online catalogues that can be accessed on the Web. 

OSH information seelmrs should be aware that many of the printed paper versions of catalogues, indexes and abstracts to the literature are also available on computers throughout the world. It is not now necessary to spend many hours travelling to sources of information, checking manually through periodicals, etc., or worse, not being able to access the information at all. These facilities have been outlined in the chapter by Cowie and Richardson. 

The third important source for information on modem Raman spectroscopy are the books cataloguing the proceedings of the International Conference on Raman Spectroscopy (ICORS) [37]. ICORS is held every two years at various international locations and features hundreds of contributions from leading research groups covering all areas of Raman spectroscopy. Although the published presentations are quite limited in length, they each contain references to the more substantial works and collectively provide an excellent overview of current trends in Raman spectroscopy. A snapshot or brief summary of the 1998 conference appears at the end of this chapter. 

To assist in choosing the type of source and which source material is best suited for a given evaporation material, reference should be made to the study of the information given in [252] and [258], and in the coating material catalogues of suitable companies. 

Research projects in pharmaceutical industry that are in an early phase need bioactive chemotypes as potential lead structures for optimization. Hits with a medium or even weak activity can serve as leads if the overall profile looks attractive. HTS of the in-house compound libraries is the most common source of these lead structures. If information about the 3D structure of the target and/or about bioactive ligand(s) is available, virtual screening can be used to add further active chemotypes either from the existing compounds, for example, from vendor catalogues, or from the virtual chemical space, for example, from virtual combinatorial libraries. Virtual screening can also be used to select a subset from the in-house screening collection if a full HTS is not possible due to cost or time limitations. 

As I mention repeatedly, do not ignore the suppliers catalogues and application naes. Catalogues are very helpful when choosing a detector, and are likely to be more up-to-date than other sources of information. Detector and system manuals are essential when setting up. 

Mflii-steady-state concentration of triplets during the population inversion. There are now many laser dyes available which cover the full spectral range from the IR to the UV, and the best sources of up to date information are manufacturer s catalogues. However there are a few dye classes which are particularly useful as laser dyes, where the basic chemical skeleton is retained but changes in substituent are used to shift absorption and emission wavelengths, e.g. basic structures of 2.1, 4.1, 4.2, 4.6. 

Quartz cells are significantly more expensive than those made of glass. Many different types of cell are available for specific applications anaerobic, flow, micro, sipper, stirrer, stopcock, and others examples of some of these cells are shown in Fig. 14.1. Cell manufacture catalogues are an excellent source of information about materials and what types of cell are commercially available [5]. Standard absorption cells typically have a 1 cm path length and square cross-... 

The block called solutions is the core of the catalogue, as it contains all significant information (Figure 4.11). An indication of sources enables one to revert easily to original documents in order to search for detailed information. The procedural... 

Details of good quality, reliable varieties for England and Wales, from UK and European plant breeders, can be found in the Recommended Grass and Clover Lists leaflet which is funded by the Grass Levy Scheme and is published annually using data from trials carried out by NIAB TAG and evaluated by a panel of experts. Farmers in Scotland and Northern Ireland have access to information of a similar quality published by SAC and DARD respectively. Seed catalogues and the online information provided by reputable seed merchants can also be valuable sources of information. Details of grasses which have been bred for amenity and sports surfaces are provided by the Sports Turf Research Institute (STRI) also on an armual basis. 

The main purpose of this book however is to bring the literature on laser lines up-to-date with a new compilation of all the known cw lines. The early compilations of this nature [1.10-12] were quickly outstripped by new discoveries, and the last comprehensive update of cw lines appeared in 1981 [1.14] (it contained 1350 lines). Although a review of frequency measurements appeared recently [1.13], only 914 of the lines in the present compilation of 4555 have had their frequencies measured (50 of them since publication of [1.13]). The catalogue which appears in Part II of this book was commenced several years ago because of the need for an up-to-date source of information on laser lines suitable for use in astronomical heterodyne receivers (see for example [1.15]). In common with a number of applications, these receivers require the use of cw lasers at specific frequencies. Spectral coverage is now good enough that the publication of a new, exhaustive catalogue seems opportune.
