Rules and guidelines

The pinch design method developed earlier followed several rules and guidelines to allow design for minimum utility (or maximum energy recovery) in the minimum number of units. Occasionally, it appears not to be possible to create the appropriate matches because one or other of the design criteria cannot be satisfied.

The states of Europe have a deep history of pharmacopeial activity that even now is evidenced in publications by the United Kingdom, Denmark, Sweden, Spain, and Russia that date from the late 18th century. European unification as a modern process saw the creation of a common drug standard in 1964. The European Pharmacopoeia (EP) grew out of subsequent discussions within the European Economic Committee to establish a common set of rules and guidelines for the quality of drugs among the member states. 

This section lists fundamental potential pitfalls when working with a vacuum system. If you read no other section in this book, read this one. By following the rules and guidelines that you are directed to within this section, many hours, and perhaps weeks, of problems will be avoided. It is better to avoid the situation of not having enough time to do it right, but plenty of time to repair the wrong. This list is not meant to be comprehensive—it cannot be. It is, however, a collection of the more common disasters that occur on a laboratory vacuum system. 

There is no completely rational or reliable strategy for solving structures from spectroscopic data. The precise route to a structure will depend on how much background and spectroscopic information is available about the molecule, and on which of the spectra appear most useful. Nevertheless, there are some useful rules and guidelines about the right way to tackle such a problem. Further details will be found in Chapter 5 of our main book. 

As neural network theory has been developed, the empiricism associated with the choices at each step, has given ways to heuristic rules and guidelines [5.48, 5.49]. Nevertheless, experience still plays an important part in designing a network. The network depicted in Fig. 5.13 is the most commonly used and is called the feedforward network because all signals flow forward.

Chemical laboratories are potentially dangerous wo places and accidents in the laboratory can have serious and tragic consequences. However, if you are aware of potential hazards, and work with due care and attention to safety, the risk of accidents is small. Some general guidelines for safety in the laboratory are presented in this section. In addition to these principles you must be familiar with the safety regulations in force in your area and the rules and guidelines applied by the administrators of your laboratory. 

For more than a century, scientists have intensely studied the geometry of compounds. Swiss chemist Alfred Werner (1866-1919) won the Nobel Prize in 1913 for his pioneering work predicting the shapes of mole-eules. Since those early studies, scientists have developed rules and guidelines based upon physical laws that predict molecular shapes. 

The science that underpins steam sterilization is well known and has been long established. It is the preferred method of sterilization in the pharmaceutical industry it is used for sterilization of aqueous products in a wide variety of presentations, for sterilization of equipment and porous materials required in aseptic manufacture, in microbiology laboratories for sterilizing media and other materials, and for sterilization of massive systems of vessels and pipework [steam-in-place (SIP) systems]. Numerous rules and guidelines have been published on the topic, yet steam sterilization and particularly bio-validation of steam sterilization is still a subject for controversy and debate. 

In the European Union, the design, manufacture, and use of pressure systems is covered by the Pressure Equipment Directive (Council Directive 97/23/EC) whose use became mandatory in May 2002. European standard EN 13445 provides similar rules and guidelines to the ASME BPV Code. The design of fiber-reinforced plastic vessels is covered by European standard EN 13923. 

In the European, U.S. and Japanese markets, the International Conference on Harmonization (ICH) is attempting to standardize regulations and testing for pharmaceutical products. This conference was formed to bring about one set of rules and guidelines for the member states, enabling trade of pharmaceutical products between member nations to proceed more smoothly. 

It is usually the Committee for Drug Information of the LMI (Norwegian Association of Pharmaceutical Manufacturers) that supervises promotional activities and may impose fines on pharmaceutical companies in cases of breach of ethical rules and guidelines. The fines may be in the order of NOK5000-300 000 The Committee is authorised to make decisions only in cases where the defendant is a member of the LMI or has approved the industry s ethical guidelines. This is the case for the vast majority of companies responsible for the sale of pharmaceutical products in Norway, and in practice the Committee is an important authority.
