Evaluated data

Evaluation data taken from the more than 8 thousand reports of the laboratory and field wire ropes inspections show that the visual methods and life time criteria are non adequate to real durability of the ropes in service [4]. The data show that only a very small percentage of all ropes was replaced in a proper time, when one has used a visual inspection. 

Both database sources contain evaluated data on millions of compounds, and allow the retrieval of bibliographic information and of structures. 

Beilstein File. Beilstein first went on-line on STN International in December 1988 with information on 350,000 compounds, and several months later it was also on Dialog. Beilstein Online now comprises data on five million compounds. The organic substance records contain the critically reviewed and evaluated documents from the beilstein Handbook of Organic Chemist main volume and supplements 1—5, which cover the chemical Hterature from 1779 through 1979. These evaluated data are indicated as Handbook Data in the notes of Hterature references. The Beilstein Eile also contains organic substance records for unreviewed excerpts from the primary Hterature from 1980 to 1991.

Hazard identification involves gathering and evaluating data on the types of health injury or disease that may be produced by a chemical and on the conditions of exposure under which injury or disease is produced. It may also involve characterization of the behavior of a chemical within the body and the interactions it undergoes with organs, cells, or even parts of cells. Hazard identification is not risk assessment. It is a scientific determination of whether observed toxic effects in one setting will occur in other settings. 

Risk characterization is defined as the integration of the data and analysis of the above three components to determine the likelihood that humans wiU. experience any of the various forms of toxicity associated with a substance. When the exposure data are not available, hypothetical risk is characterized by the integration of hazard identification and dose—response evaluation data. 

Measuring the barrier properties of polymers is important for several reasons. The effects of formulation or process changes need to be known, new polymers need to be evaluated, data are needed for a new apphcation before a large investment has been made, and fabricated products need to have performance verified. For some apphcations a full range of data is necessary, including P, Z9, and S plus the effects of temperature and humidity.

Techniques to use for evaluations have been discussed by Cox and Tikvart (42), Hanna (43) and Weil et al. (44). Hanna (45) shows how resampling of evaluation data will allow use of the bootstrap and jackknife techniques so that error bounds can be placed about estimates. 

Information about this splendid compilation came to me from a chemist, Robert Weast (1985), who was editor from 1952 until 1988... 37 years He also informed me that the creation (jointly by the American Chemical Society and the American Institute of Physics) of the Journal of Physical and Chemical Reference Data, which began publication in 1972, was encouraged by the results of a survey which indicated how widely the Rubber Bible was used. Weast describes this journal as a truly outstanding source of critically evaluated data . In saying this, he underlined the crucial role of editors and contributors critical judgment in selecting data for such compilations. David Tide, the editor of the journal, in 1989 succeeded Robert... 

This section reflects on the limitations of the PSA process and draws extensively from NUREG-1050. These subjects are discussed as plant modeling and evaluation, data, human errors, accident processes, containment, fission product transport, consequence analysis, external events, and a perspective on the meaning of risk.

Strigle [82] and Kister [93] point out the importance of evaluating data where available to reduce the need for interpolating the GPDC charts. The question of reasonably accurate ( 10 to 15%) flooding pressure drop data has been studied by Kister [93], and the results suggest that the establishment of flooding pressure drop curves... 

Other major sources of data on the thermochemistry of sulfur-containing compounds are the review by Benson19, which is of particular value in evaluating data on radicals and other labile species, and the review of the present author on the thermochemistry of the inorganic S—O—F compounds20. 

As class discussions relate textbook topics to the environmental issues, students become aware of the difficulty of applying what they have learned in class to more complex situation. Although frustrate by the absence of simple right answers, students can be taught to appreciate the process by which scientists evaluate data and adjust hypotheses. 

Examples were given earlier of a few systems for which the theoretical speciation of metals was calculated, and a few others in which it was analyzed experimentally, at least into some subgroups if not specific species. These approaches have rarely been combined to critically evaluate data or hypotheses regarding metal transport through a real system. One study, already noted...

Self-report questionnaires containing a mixture of open and forced-choice questions. These could be distributed amongst mentors, mentees, relationship supervisors, line managers and program co-ordinators. In addition, you could also use this method to consult with peers, customers and/or suppliers -i.e. anyone who could provide you with valuable evaluation data. Make sure, however, that you customize the questions to the group of respondents you are addressing. 

With regard to the question of who should provide the evaluation data, the answer involves the following ... 

The small NBS program in chemical engineering should receive substantially greater funding to fulfill critical needs for evaluated data and predictive models. The committee supports NBS plans to focus on data needs in emerging technology areas such as biotechnology and advanced materials. 

The National Bureau of Standards has a unique role to play in supporting the field of chemical engineering. It should be the focal point for providing evaluated data and predictive models for data to facilitate the design, the scale-up, and even the selection of chemical processes for specific applications.

This book, written by two passionate analysts, treats the application of statistics to analytical chemistry > 2 in a very practical manner. A minimum of tools is explained and then applied to everyday, that is, complex situations. The examples should be illuminating to both beginners and specialists from other fields in their quest to evaluate data and make decisions. 

Web-based data collection and management systems provide a mechanism for remote data entry, where entered data are added to a centralized database once the submit button is pressed. They can be designed to automate the various aspects of clinical trials such as eligibility evaluation, data collection, and tracking specimens. They also serve as a resource site for participating sites to access trial-specific information, facilitate communication, track data queries and their resolutions, and allow administrative management of trials [28, 29]. For these reasons, they play an important role in facilitating the conduct of international clinical trials. 

The National Institute of Standards and Technology (NIST) molten salts database has been designed to provide engineers and scientists with rapid access to critically evaluated data for inorganic salts in the molten state. Properties include density, viscosity, electrical conductance, and surface tension. Properties for approximately 320 single salts and 4000 multicomponent systems are included, the latter being primarily binary. Data have been abstracted from the literature over the period 1890-1990. The primary data sources are the National Bureau of Standards-National...

Currently, nutrient analytical methods development often utilizes the method of standard additions as an intrinsic aspect of the development process. Essentially, the analyte to be measured exists in the matrix to which an identical known pure standard is added. The spiked and non-spiked matrix is extracted and analysed for the nutrient of interest. By spiking at increasing levels the researcher can establish, to some degree of certainty, the recovery and linearity of the standard additions. One can also evaluate data to determine reproducibility, precision, and accuracy. Unfortunately, the method of standard additions does not allow the evaluation of the method at nutrient concentrations less than 100 % of the endogenous level.

Guidelines for acceptability of NADA and non-NADA methods are the same. For the determinative procedure, the criteria described in Method Criteria for accuracy and precision are used to evaluate data generated at participating laboratories. There are no criteria for accuracy in the analysis of the incurred residue samples however, the overall data set is reviewed to see if there is general agreement between results obtained by contract laboratories and relative to the levels reported in the sponsor s laboratory.
