Field test improved results

Tables I and II present the results of the Work Group discussions for the screening and site-specific level models, respectively. The assessment in these tables is based on a ranking scale between 0 and 100 0 indicates situations where no testing has been attempted and 100 identifies areas where extensive testing has been completed with sufficient post-audits to validate the predictive capability of relevant models. The scores can also be interpreted to mean the extent to which additional field testing would improve our understanding of how well the models represent natural systems. It is important to note that the scores do not indicate model accuracy per se they show the degree to which current field testing has been able to identify or estimate model accuracy.

As part of the radon program at EML to develop or improve and field test radon monitors, a modified activated carbon device (Warner, 1986) was developed to obtain higher measurement sensitivity. As a result, we have surveyed 380 buildings in six states in the eastern United States. The purpose of the measurements reported in this paper was to test the feasibility of the new version of the passive activated carbon device and to obtain data on indoor radon levels in different geographical locations. 

A 1 3 scale model of a single electrode from the fringing-field line shown in Figure 2 was made and tested ( ). The results of this test show that the fringing field line is suitable for the treatment of soils in which the depth of contaminant penetration is less than three feet and where the required treatment temperatures do not exceed 130°C, Additional development and testing is, however, necessary to fully explore the limitations of the fringing field lines, and in particular, to determine ways to improve the penetration depth. 

Ethoxylated Sulfonates The condensation of fatty alcohols and ethylene oxide yields non-ionic sufactants, which are low emulsifiers and low foamers. The ethoxylated sulfonates can be prepared by sulfonating ethoxylated alcohols. Sulfonated alcohols are excellent foamers as are the sulfonated versions of non-ionic surfactants. The ethoxylated sulfonates are also known as alcohol ether sulfonates. The laboratory results and field tests indicate that the mixed surfactant formulation composed of a petroleum sulfonate and ethoxylated sulfonate or alcohol can improve oil recovery as well as increase salinity tolerance. Ethoxylated sulfonates also lead to a greater flexibility in fluid system design because the degree of ethoxylation and/or the chain length may be varied to adjust slug viscosity. 

Scriven (1967) first distinguished between the formative and summative roles of evaluation. Formative evaluations, conducted during the implementation of a safety program, provide directors information that helps improve the program. Formative evaluation typically involves content inspection by experts, pilot tests with small numbers of workers, field tests with larger numbers of workers in several plants, and so forth. Each step results in immediate feedback to the developers, who would then use the information to make necessary revisions (Worthen and Sanders 1987,34). 

ABSTRACT Type of collapsibility of site is an important content in evaluation of loess collapsibility, the results calculated according to indoor test is often contradict with field test results. In order to solve the contradiction, the paper analyzes the factors that brings about difference in indoor and field test results based on the in-situ immersion test results in loess site completed in recent years, makes a study of the influence of discontinuous distribution of collapsible loess on collapse settlement, and presents the improved empirical formula for collapse settlement calculation under overburden pressure. The results show that indoor collapsibility test succeeds but impairs the correlation between factors such as loess property, stratum configuration, stress history, buried depth and settlement by immersion, during collapse settlement calculation, the correction of these influential factors shall be taken into consideration the standard used for judgment of loess as to whether it is collapsible may be properly heightened, in case of discontinuous distribution of collapsible loess, stress redistribution effect shall be taken into account.
