Computerised information

It is expected that the results of research will be carefully recorded in a form that will allow continuous and future access for analysis and review. Attention should be given to annotating and indexing notebooks and documenting computerised information to facilitate detailed review of data. All data, even from observations and experiments not directly leading to publication, should be annotated, indexed, and documented." ... 

While not all information systems make extensive use of computers, computerised information systems are no longer adjuncts to the way we conduct science and business they are integral components of our entire organisation. All scientists and administrators as well as clerical employees should be utilising computers in their routine operations. This fact places considerable pressure on the way computer systems are designed today. 

Selection can be simplified if the product data is either filed on a computer data base or simply in a tabular form as indicated in Table 4.1 where all the information is given in similar units based on in-house test results. Computerised information is available as a commercial package covering a wide range of materials and application needs. 

Insufficient information about the properties, layout pattern of small defects, potential for their growth in time, usually leads either to an unjustified rejection (repair) or to underestimation of the importance of the defect and, as aconsequence, construction failure. Use of automated computerised means of control allows safe service of the old constructions, periodically repeating the UT and monitoring the development of discontinuities in the metal. The main idea of such policy is periodical UT of development of discontinuities or, in a more general form, monitoring of the metal condition. 

The Drug Information Centre should always be available by telephone, but can also answer inquiries by mail, e-mail, Internet based formularies or by functions integrated into local technical systems, such as computerised medical records. 

This pulsed wave process provides simultaneous information on all the frequencies present. The generalisation of this process, which can be computerised and allows the study of less sensitive nuclei such as 13C, has led to major developments in NMR. 

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. 

Sequential signals are surprisingly widespread in chemistry, and require a large number of methods for analysis. Most data are obtained via computerised instruments such as those for NIR, HPLC or NMR, and raw information such as peak integrals, peak shifts and positions is often dependent on how the information from the computer is first processed. An appreciation of this step is essential prior to applying further multivariate methods such as pattern recognition or classification. Spectra and chromatograms are examples of series that are sequential in time or frequency. However, time series also occur very widely in other areas of chemistry, for example in the area of industrial process control and natural processes. 

The computerised drug registration system to capture all information pertaining to licences issues in relation to drug registration was commissioned in January 1989. This system also has an enforcement module which captures data on inspection and legal action instituted against offenders.
