Esterification ofTerephthalicAcid. Esterification of terephthaUc acid is also used to produce dimethyl terephthalate commercially, although the amount made by this process has declined. Imperial Chemical Industries, Eastman Kodak, Amoco, Toray, Mitsubishi, and Mitsui Petrochemical have all developed processes. Esterification (qv) generally uses a large excess of methanol in a Hquid process at 250—300°C. The reaction proceeds rapidly without a catalyst, but metal catalysts such as zinc, molybdenum, antimony, and tin can be used. Conversion to dimethyl terephthalate is limited by equiHbrium, but yields of 96% have been reported (75,76). 

The approxmations reviewed so far were all developed for the low-piston Mach number regime. Cambray and Deshaies (1978), on the other hand, developed a solution of the similarity equations by asymptotic expansions in powers of high-piston Mach numbers. These solutions are supposed to hold for piston Mach numbers higher than 0.7. Finally, Cambray et al. (1979) suggested an interpolation formula to cover the intermediate-piston Mach number range. 

We have attempted to cover all aspects of the field, trying to display its richness of thoughts and models, as well as its still considerable shortcomings. However, it is not possible to detail all developments and we apologize for any omissions which others may have included. 

Anyone working in a laboratory wOl have access to information that is not public. If the employer is engaged in development work, for instance, news of such work should be confidential. A new employee may be required to sign a secrecy agreement under which all developments made by the employee become the company s exclusive property. When signing such an agreement, the author made certain that some formulation principles which he had developed prior to employment with that company were excluded. 

It is therefore vital that the United States in particular and all developed countries, emphasize nuclear power in meeting electric power needs, and to the extent possible substitute uranium for fossil fuel. It is equally critical that, as aging nuclearfiacilities are taken out of commission, replacement power generation be nuclear and not fossil fuel. 

On May 1-2, 1974, a field from the Zhdanov Collective Farm in the Krivoozersk Region was treated with polychlorpinen. On May 15-25, 57 female collective farm workers worked in this field with no complaints. From May 30-June 6 the field was fertilized with ammonium nitrate, and on June 8 it rained. When, on June 11, the same 57 women worked in this field again, by 2pm all developed acute gas poisoning (the concentration of polychlorpinen in the air over the field three days later was only 0.04 mg/m3). 

Poor hydrogen utilization results in less than optimal thermal efficiencies for all developing processes. 

Established Practices Codes, standards, regulatory requirements, industry guidelines, recommended practices, and supplier specifications have all developed over the years to embody the collective experience of industry and its stakeholders in the safe handling of specific materials. These should be the engineer s first resource in seeking to design a new facility. 

Packages are the containers for all development work, from models to documentation to code and test (see Figure 7.27). Packages define units of versioning, configuration management, and reuse. 

All development activities Actions by developers using tools on artifacts... 

Treating all development artifacts as a part of a package would seem to be common sense, yet surprisingly few projects practice it and surprisingly few methods require it. Knuth s Web is based on strongly integrating code and documentation but does not address modeling or specification. 

Particle size will always be expressed in terms of diameter rather than radius in this chapter. In all developments in this chapter, the particles will be assumed to be spherical. Consequently, when applying the results to other than spherical particles, that equivalent spherical diameter must be used which would correspond to the phenomenon involved. 

Departments or boards of health and industrial hygiene services are integral parts of the organization of all states, the District of Columbia, and the autonomous territories of the United States, as well as the federal and provincial governments of Canada and all developed nations. 

Also enshrined in this ideal is the concept that the information gathered should be made freely available to all developing countries throughout the world. The steps necessary to achieve these objectives are -... 

To establish a microbial-limit testing history, all development, clinical, scale-up and process validation batches of new nonsterile dosage forms would be tested to verify that the pharmaceutical ingredients, manufacturing process, and packaging does not contribute to the bioburden of the product. After the testing history has been... 

Fungal disease favored by wet cool summers. The main source is infected seed. The fungus also survives in soil and crop debris for three to four years. Infection does not spread between bulbs in store, but symptoms do not all develop at the same time. 

Pharmaceutical development of a medicinal product must retain the drug s promising in vitro pharmacological activity and provide a predictable in vivo response. The marketed product must be stable, correctly packaged, labelled and easily administered, preferably by self-administration. The product must also be economical to manufacture on a large scale by a method that ensures product quality. In addition, development and eventual production processes must comply with the regulatory requirements of proposed market countries, and all development studies must be performed to acceptable levels of quality assurance. 

The FDA Modernisation Act of 1997 (FDAMA) included a number of elements that have increased the number of studies being performed on children. This was largely successful at increasing data on paediatric studies in the United States and has been now replaced by the Best Pharmaceuticals for Children Act, 4 January 2002 (Public Law No. 107-109). The European Commission has released (29 September 2004) proposed regulations that aim at promoting medicines for children which draw heavily on the successful FDA model. The regulations will probably be transposed into law in individual Member States in 2006. This means that all development plans will have to actively consider paediatric studies in the future.
