Acceptability considerations

Where small and/or single contaminant effluents are encountered, packaged treatment plants may be acceptable. Consideration should, however, be given to capital cost, payback period, reliability of equipment, maintenance, plant-life expectancy and contaminant-removal efficiencies. [Pg.20]

Acceptance considerations the comprehensible and quantitative NA concept has to meet regulatory requirements, for decision-making authorities may have to take into account further criteria such as future use, property aspects, possibility of combining NA with other techniques. [Pg.208]

Field and offshore operations take place in many parts of the world (high seas, remote jungles, vast deserts and mountain ranges). In some settings, you may be working for several months at a time without a break. You will need to be prepared to accept considerable disruption to your personal and home life. Communal living with the same set of people means you need to get on well with others, both in and outside the work situation. [Pg.31]

To interpret such data In terms of the permissible stresses for a pressure tube material, it Is necessary to decide how much strain can be tolerated In the particular design of pressure tube. Por a vertical tube reactor such as the SGHWR, this question becomes one of how much Increase of diameter (and associated wall thinning) is acceptable. Considerations such as the effect of pressure tube diameter on coolant flow, on fuel element support or on calandria tube gap do not provide a strain limit of less than 5. ... [Pg.120]

Hartung et al., 2013). However, they emphasize validating in vitro systems to ensure reliability and suitability for humans thus, the data can be invaluable and effective. Schechtman (2002) reviewed the implementation of the 3Rs (refinement, reduction, and replacement) validation and regulatory acceptance considerations for alternative toxicological test methods and suggested pros and cons of in vitro testing. [Pg.658]

Two generally accepted models for the vapor phase were discussed in Chapter 3 and one particular model for the liquid phase (UNIQUAC) was discussed in Chapter 4. Unfortunately, these, and all other presently available models, are only approximate when used to calculate equilibrium properties of dense fluid mixtures. Therefore, any such model must contain a number of adjustable parameters, which can only be obtained from experimental measurements. The predictions of the model may be sensitive to the values selected for model parameters, and the data available may contain significant measurement errors. Thus, it is of major importance that serious consideration be given to the proper treatment of experimental measurements for mixtures to obtain the most appropriate values for parameters in models such as UNIQUAC. [Pg.96]

Decommissioning is often a complex and risky operation. The five key considerations are the potential impact on the environment, potential impact on human health and safety, technical feasibility, costs of the plan, and public acceptability. [Pg.365]

The basic condition of the Standard application - the availability of stable coupled probabilistic or the multiple probabilistic relations between then controlled quality indexes and magnetic characteristics of steel. All the probabilistic estimates, used in the Standard, are applied at confidence level not less than 0,95. General requirements to the means of control and procedure of its performance are also stipulated. Engineers of standard development endeavoured take into consideration the existed practice of technical control performance and test at the enterprises that is why the preparation of object control for the performance of nondestructive test can be done during the process of ordinary acceptance test. It is suggested that every enterprise is operated in correspondence with direct and non-destructive tests, obtained exactly at it, for detailed process chart and definite product type, however the tests have long since been performed after development of the Standard displayed that process gives way to unification. [Pg.25]

Without fiirther considerations, the only acceptable real quantum-mechanical wavefiinctions for an n-particle system would appear to be those for which... [Pg.26]

The efficiency of separation of solvent from solute varies with their nature and the rate of flow of liquid from the HPLC into the interface. Volatile solvents like hexane can be evaporated quickly and tend not to form large clusters, and therefore rates of flow of about 1 ml/min can be accepted from the HPLC apparatus. For less-volatile solvents like water, evaporation is slower, clusters are less easily broken down, and maximum flow rates are about 0.1-0.5 ml/min. Because separation of solvent from solute depends on relative volatilities and rates of diffusion, the greater the molecular mass difference between them, the better is the efficiency of separation. Generally, HPLC is used for substances that are nonvolatile or are thermally labile, as they would otherwise be analyzed by the practically simpler GC method the nonvolatile substances usually have molecular masses considerably larger than those of commonly used HPLC solvents, so separation is good. [Pg.79]

Although theoretical considerations still fall short of the goal of giving absolute values of M from Vj, they do suggest ways in which empirical calibrations can be extended beyond the stringent requirement of identical polymers under identical conditions being the only acceptable calibrations. [Pg.649]

Animals that do not readily accept pelleted feeds may be enticed to do so if the feed carries an odor that induces ingestion. Color development is an important consideration in aquarium species and some animals produced for human food. External coloration is desired in aquarium species. Pink flesh in cultured salmon is desired by much of the consuming pubHc. Coloration, whether external or of the flesh, can be achieved by incorporating ingredients that contain pigments or by adding extracts or synthetic compounds. One class of additives that imparts color is the carotenoids. [Pg.21]
