For the system factor, use values out of Table 1 except for the last item in that table (foam-stable systems) use 0.30. 

Assists in identifying appropriate analytical laboratories to evaluate environmental samples (e.g., soil, water, sludge, waste, air) for characterizing hazards at a site. The system factors type of sample, suspected pollutants, user s needs for on-site evaluation, and laboratories locations, capabilities, and ( ualiricalions. 

Emphasis on the Modification of System Factors as a Major Error Reduction Strategy This emphasis replaces the reliance on rewards and pLmishment as a means of error control which characterizes the TSE approach. 

In rare cases of a systemic release, kinins have the potential to cause severe hypotension. Uncontrolled activation of the contact system (Fig. 3) is thought to trigger a massive formation of kinins under certain pathological conditions [3]. For instance, this situation is seen in patients with underlying diseases such as systemic inflammatory response syndrome (SIRS) due to sepsis or trauma. SIRS progression is accompanied by depletion of contact system factors and low levels of H-kininogen and plasma kallikrein are indicative of a... 

Methyl parathion is only slightly soluble in pH 7 water (55-60 ppm). This affects its mobility in water and its ability to be leached or solubilized into the water phase of a soil-water system. Factors most likely to affect the adsorption of methyl parathion in soil are organic matter content and cation exchange capacity. In soils of low organic matter (e.g., subsurface soils), calcium concentration, which affects the hardness of the water, may also be important (Reddy and Gambrell 1987). Several studies have shown... 

Prothrombin and several other proteins of the blood clotting system (Factors VII, IX and X, and proteins C and S) each contain between four and six y-carboxygluta-mate residues which chelate calcium ions and so permit the binding of the blood clotting proteins to membranes. In vitamin K deficiency or in the presence of warfarin, an abnormal precursor of prothrombin (preprothrombin) containing little or no y-carboxyglutamate, and incapable of chelating calcium, is released into the circulation. 

OA develops when systemic factors and biomechanical vulnerabilities combine. Systemic factors include age, gender, genetic predisposition, and nutritional status. Age is the strongest predictor of OA, although advanced age alone is insufficient to cause OA. 

Limited cost data are available for the construction and operation and maintenance (O M) of ET cover systems. The available construction cost data indicate that these cover systems have the potential to be less expensive to construct than conventional cover systems. Factors affecting the cost of construction include availability of materials, ease of installation, and project scale. Locally available soils, which are usually less costly than imported clay soils, are typically used for ET cover systems. In addition, the use of local materials generally minimizes transportation costs.3945... 

If the response from a system is to be set to a specified level by setting the system factors to certain levels, then the behavior of the system must be known. This statement is at the heart of most research and development projects. 

We will take the broad view that the system transform is that part of the system that actively converts system factors into system responses. A system transform is not a description of how the system behaves a description of how the system behaves (or is thought to behave) is called a model. Only in rare instances are the system transform and the description of the system s behavior the same - the algebraic system of Figure 1.2 is an example. In most systems, a complete description of the system transform is not possible - approximations of it (incomplete models) must suffice. Because much of the remainder of this book discusses models, their... 

A response surface is the graph of a system response plotted against one or more of the system factors [Khuri and Cornell (1987)]. We consider here the simplest case, that of a single response plotted against only one factor. It is assumed that all other controllable factors are held constant, each at a specified level. As will be seen later, it is important that this assumption be true otherwise, the single-factor response surface might appear to change shape or to be excessively noisy. 

Figure 2.2 is a response surface showing a system response, y, plotted against one of the system factors, x,. If there is no uncertainty associated with the continuous response, and if the response is known for all values of the continuous factor, then the response surface might be described by some continuous mathematical model M that relates the response y, to the factor x. ... 

Comment on known and unknown, controlled and uncontrolled measurement system factors and their influence on the quality of information about the system under study. 

Figure 12.4 is a pseudo-three-dimensional representation of a response siuface showing a system response, plotted against the two system factors, x, and X2. The...
