Contingent variation

This is one of our working formulas. It is an approximation, of course, but we are presently unable to do better evidently, by implementing this approximation, we possibly transfer additional contingent variations of the sh/ bond energy to other bonds formed by atom 1 in the molecule. With this reservation in mind, we shall illustrate the use of Eq. (10.15) in Chapter 15, thus revealing instructive bond properties. 

Examples and anecdotes are often useful an overreliance on personal experience or "war stories" loses attention. Similarly, an argument that tries to address every conceivable contingency, quirk, and variation will almost certainly fail to convince, because of simple overkill. 

Each element ,y of a contingency table X can be thought of as a random variate. Under the assumption that all marginal sums are fixed, we can derive the expected values E(x,y) for each of the random variates [1] ... 

Another electric signal recorded from the surface of the skull is termed contingent negative variation (CNV). This is a very late potential fluctuation in the parietal region that arises when a subject participating in a reaction time experiment is advised, through a warning stimulus, of the imminence of another stimulus to which he or she has to respond. 

A technique known as contingent negative variation (CNV) measures brain-wave reaction to olfaction. These types of studies have shown the eftect of materials such as lavender and nutmeg in reducing stress or anxiety, and the ability of oils such as peppermint to stimulate brainwave activity. CNV research was incorporated into the development of the fragrance for a consumer personal care product launched in the late 1980s. 

Contingent upon a number of parameters that are all extensively described by Boschetti and Righetti (6), the method of sample processing allows an increase of the number of proteins that can range from 50% to more than five times the number of proteins found in the nontreated sample. Variations are also possible with the use of different loading conditions and elutions as well as analytical methods.

Unforeseen events, such as strikes, storms, floods, price variations, and other contingencies, may have an effect on the costs for a manufacturing operation. When the chemical engineer predicts total costs, it is advisable to take these factors into account This can be accomplished by including a contingency factor equivalent to 1 to 5 percent of the total product cost. 

Contingency charges are extra costs added into the project budget to allow for variation from the cost estimate. All cost estimates are uncertain (see Section 6.3.1), and the final installed cost of many items is not known until installation has been successfully completed. Apart from errors in the cost estimate, contingency costs also help cover... 

The concept of a contingency charge to allow for variation in the capital cost estimate was introduced in Section 6.2.1, where it was suggested that a minimum contingency charge of 10% of ISBL plus OSBL fixed capital should be used. 

Based on information supplied by manufacturers, capital costs of wood gasification systems vary from approximately. 30- 1.10/ MJ/D ( 5,000 to 20,000/ODT/D) of capacity.(3) This wide variation is the result of differences in system capacity, inclusion of specific components, varying cost assumptions, and the requirement for land and facilities. The average costs are. 55-. 65/ MJ/D ( 10,000 to 12,000/ODT/D) for a system which includes materials handling equipment, gasification equipment and ancillary systems such as controls but excludes a boiler, land, building, contingencies and fees.
