Once you are experienced at finding transition structures for a particular class of reactions, you will probably go directly to the technique that has been most reliable for those reactions. Until that time, the checklist above is our best advice for finding a transition structure with the least amount of work for the researcher and the computer. Regardless of experience, it is common to experience quite a bit of trial and error in finding transition structures. Even experienced researchers find that the way they have been regarding a reaction is often much more simplistic than the molecular motions actually involved. 

This book grew out of a collection of technical-support web pages. Those pages were also posted to the computational chemistry list server maintained by the Ohio Supercomputer Center. Many useful comments came from the subscribers of that list. In addition, thanks go to Dr. James F. Harrison at Michigan State University for providing advice born of experience.

Several international organizations have been estabUshed that can offer conservation advice or even practical help in areas of the world where such is not readily available. The International Centre for the Study of the Preservation and the Conservation of Cultural Properties (ICCROM), based in Rome, is an intergovernmental organization that serves over 80 member states, among which is the United States. In the United States, the National Institute for Conservation of Cultural Property (NIC) serves as a fomm to faciUtate information distribution and exchange, coordination and planning between institutions and representatives of the various professions, and to promote pubHc and government awareness of the need for conservation of the cultural... 

In a typical isothermal process, 70% hydrogen peroxide is added to 98% sulfuric acid, and subjected to rapid stirring and efficient cooling, so that the temperature does not rise to above 15°C. If equimolar quantities of reactants are used, the product contains 42% H2SO and 10% H2O2. Although the reaction may seem simple, many of its features are critically important and it should only be attempted foUowiag advice from speciaUsts.

Best Pra.ctices, Technology leaders must provide the direction for improving work processes as well as the work itself. They should seek the best known ways to carry out R D best practices. There is considerable advice available on best R D practices. 

The first clues to the treatment of scurvy occurred in 1535—1536 when Jacques Cartier, on advice from Newfoundland Indians, fed his crew an extract from spmce tree needles to cure an epidemic. Various physicians were recommending the use of citms fmits to cure scurvy in the mid-sixteenth century. Two hundred years later, in 1753, it was proved by Dr. James Lind, in his famous clinical experiment, that scurvy was associated with diet and caused by lack of fresh vegetables. He also demonstrated that oranges and lemons were the most effective cure against this disease. In 1753, inM Treatise on the Scurvy[ Lind pubhshed his results and recommendations (7). Eorty-two years later, in 1795, the British Navy included lemon juice in seamen s diets, resulting in the familiar nickname "limeys" for British seamen. Evidence has shown that even with undefined scorbutic symptoms, vitamin C levels can be low, and can cause marked diminution in resistance to infections and slow healing of wounds. 

In the United States further information and advice is readily available from the Chlorinated Paraffin Manufacturers Association (CPIA) based in Washington D.C. 

Organic peroxides need to be stored separately from the polyester resins and promoters. If a peroxide is contaminated with a promoter, violent decomposition can result. Promoters should always be thoroughly mixed into the resin prior to the addition of the peroxide to prevent violent peroxide decomposition. Peroxides can become unstable if stored for too long or at too high a temperature. Peroxide manufacturers advice for storage and disposal must be stricdy followed.

For estimating filtration rate (therefore, operating pressure and size of the filter), washing characteristics, and other important features, small-scale tests such as the leaf or pressure bomb tests described earlier are usually essential. In the conduct and interpretation of such tests, and for advice on labor requirements, maintenance schedule, and selection of accessory equipment the assistance of a dependable equipment vendor is advisable. 

The relatively high prices of pulp and paper filters reflect the construction features that accommodate the veiy high hydraulic capacity that is required. The absence of data for some common types of filters, in particular the filter press, is explained by Hall as due to the complex variety of individual features and materials of construction. For information about missing filters and for firmer estimates for those types presented, vendors should be consulted. In all cases of serious interest, consultation should take place early in the evaluation procedure so that it can yield timely advice on testing, selection, and price. 

Once the initial choice of promising separator types is made, representative hquid-solid samples should be obtained for preliminaiy tests. At this point, a detailed test program should be developed, preferably with the advice of a specialist.
