Brown has pointed out that Du Pont use evaluation tests for (a-) as-received unstabilised alloys containing more than 0-03% C to check the effectiveness of the final heat treatment and (b) stabilised or special low-carbon grades after a sensitising treatment (1 h at 677°C) to determine whether susceptibility might develop during a subsequent welding operation.

As a general rule, clinical data are required as evidence to support conformity with the requirements of the Active Implantable Medical Devices (AIMD) and the Medical Device (MD) directives with regards to safety and effectiveness under the normal conditions of use, evaluation of undesirable side effects, and the acceptability of the benefit/risk ratio. Risk analysis should be used to establish key objectives that need to be addressed by clinical data, or alternatively to justify why clinical data are not required (mainly for Class I devices). The risk analysis process should help the manufacturer to identify known (or reasonably foreseeable) hazards associated with the use of the device, and decide how best to investigate and estimate the risks associated with each hazard. The clinical data should then be used to establish the safety and effectiveness of the device under the intended use conditions, and to demonstrate that any of the residual risks are acceptable, when weighed against the benefits derived from use of the device.

A very significant advance was made by Baughman and Lassiter (5) when they suggested using evaluative environments for elucidation of the environmental behavior of chemicals. This led to the EXAMS model (6), the studies of selected chemicals by Smith et al (7, 8), the development of "Unit Worlds" by Neely and Mackay (9) and Mackay and Paterson (2), and the incorporation of similar Unit Worlds into hazard assessment by Schmidt-Bleek et al (10).

Proficiency testing can be assessed in different ways. One of the most used evaluation system is that of so-called z-scores which are defined as follows (Lawn et al. [1993] Thompson and Wood [1993]) ... 

Throughout this section, and indeed the majority of this article, we have been concerned with developing and using evaluations in order to model reactions in a forward direction, that is, to predict the products from given starting materials. We now briefly consider how the reactivity functions could have application in retro-synthesis studies. 

When conducting assessments of how a chemical is likely to behave in the environment and especially how different chemicals behave in the same environment, there is incentive to standardize the evaluations using evaluative environmental models. The nature of these calculations has been described in a series of papers, notably Mackay (1979),... 

The echocardiogram is the single most useful evaluation procedure because it can identify abnormalities of the pericardium, myocardium, or heart values and quantify the left ventricular ejection fraction (LVEF) to determine if systolic or diastolic dysfunction is present. 

The purpose of pharmacy administration course work is to teach pharmacy students how to design and manage medication use systems that produce optimal results for patients. In pharmacy administration courses, students learn how to conduct medication use evaluations that measure patient outcomes. They are taught how to communicate effectively with patients and with other health care providers. Pharmacy administration courses also teach ethical and legal responsibilities to monitor drug therapy and to protect patients from problems with drug therapy. 

Separations are an important phase in almost all chemical engineering processes. Separations are needed because the chemical species from a single source stream must be sent to multiple destinations with specified concentrations. The sources usually are raw material inputs and reactor effluents the destinations are reactor inputs and product and waste streams. To achieve a desired species allocation you must determine the best types and sequence of separators to be used, evaluate the physical or chemical property differences to be exploited at each separator, fix the phases at each separator, and prescribe operating conditions for the entire process. Optimization is involved both in the design of the equipment and in the determination of the optimal operating conditions for the equipment.

The results of a classification method applied to a data set need to be evaluated in order to get an idea about the classification performance. Applying the classification procedure to the available data and then computing the percentage of misclassified objects would usually result in a far too optimistic performance measure. Therefore a resampling scheme needs to be applied leading to a sensible error estimation (see also Figure 5.1). Moreover, some of the above mentioned methods require an appropriate selection of a tuning parameter, and also for this choice a useful evaluation needs to be consulted. 

Focused drug use evaluation (drug utilization review) can be done to identify problems concerning the use of specific medicines or the treatment of specific diseases, particularly in hospitals. The qualitative methods employed in social science (e.g. focus group discussion, in-depth interviews, structured observation and structured questionnaires), can be used to investigate the motives underlying irrational use. All data collected should be used to design interventions and to measure the impact of those interventions on medicine use.

EMEA home page. In addition to information concerning the work and functioning of European drug regulatory authorities, one can find useful evaluations of drugs, in relation to their registration within the EU. 

All of these efforts were directed at standardizing excipient manufacture and use, and have been important in creating a regularized regulatory environment for excipients. Nevertheless, these steps are primarily directed toward the safety and use evaluation of existing excipients, and do little to provide any indicia of acceptability for novel ingredients. 

Many countries do not have the expertise and funds to conduct risk assessments of food additives and contaminants. JECFA performs a critical function in providing these risk assessments, and many countries use evaluations from JECFA to establish national regulatory programs for food additives and contaminants.
