Process-oriented research and development

Substances intended solely for scientific research and development in quantities less than 100 kg per year. Substances placed on the market for process-orientated research and development with a limited number of customers registered with die notifier. The aim of die notification systems is to identify possible risks posed to people and the environment from placing new substances on the market. A notification comprises data on the chemical identity of the substance an estimate of the quantity of the substance to be placed on the EC market details of the functions and uses of the substance Table 14.12 Notification bands ...

Substances used only for process-orientated research and development are exempt from registration for 5 years. The exemption can be extended for a further 5 years in exceptional circumstances, or 10 years for substances used exclusively to develop human or veterinary medicines. The manufacturer or importer has to inform the ECA of the substance identity, labelling and quantity, justify the quality, summarise the research programme and list the customers. 

Substances supplied at <10 kg a are exempt from notification, but individual Member States may choose to require appropriate technical and commercial data to be submitted. Substances supplied at <100 kg a for scientific research and development are exempt from notification, but records of supply to customers must be available for inspection by the national Competent Authority. Substances can be supplied for process-orientated research and development to a limited number of registoed customers without tonnage limit for up to 1 year (extended to 2 years if justifiable). Individual Member States can decide what information is required, up to the maximum requirement for limited notification . If substances supplied under these three exemption categories are provisionally classified as very toxic , toxic , carcinogenic , toxic for reproduction or... 

In the case of process-oriented research and development the same information as described above has to be notified to the competent authority where and before placing on the market occurs and to the competent authority of the Member State where the experiment or test is to be conducted.

Given the understanding that release of cardiac troponin into the circulation reflects myocardial cell death, it is understandable why, clinically, therapies are oriented toward inhibiting the pathophysiologic processes of thrombosis, fibrinolysis, platelet aggregation, and inflammation leading to ischemia and, ultimately, myocardial cell death. Several markers of ischemia have been proposed [2], and research and development studies are underway to adequately validate their clinical usefulness or lack of evidence. These include the topic of this chapter (ischemia-modified albumin [IMA]), as well as choline, unbound free fatty acids, and nourin. 

The term microkinetics is understood to mean the kinetics of a reaction that are not masked by transport phenomena and to refer to a series of reaction steps. For the investigation of intermediary metabolism, idealized conditions are chosen that often do not correspond to the real conditions of engineering processes. This fact makes it difficult to transfer microkinetic data to technical processes. For the purposes of technologically oriented research and the development of a process to technical ripeness, it is often sufficient to know quantitatively how a process runs without necessarily knowing why. (Macrokinetics, however, must be avoided, as they are scale dependent). Mathematical formulations are needed that reproduce the kinetics adequately for the purpose but are as simple and have as few parameters as possible. Today, even when electronic computers greatly reduce the labor of computation, the criterion of simplicity remains important due to the problem of experimental verification. The iterative nature of the process of building an adequate model is an important point that will be considered in greater detail in Sect. 2.4.
