Advantages and disadvantages for use

The macroscopic proton coefficient may be determined by graphical analysis of observed system variables according to two different procedures fractional adsorption edge linearization (6) and isotherm analysis (7 ). The procedures for calculating the macroscopic proton coefficients according to these two methods are discussed in detail below, as are their relative advantages and disadvantages for use in semi-empirical descriptions of adsorption. 

In conclusion, we have seen that changes have occurred, and will continue to occur, in the format, organization, and content of the physical chemistry examination over time. The multiple choice examination format provides a number of advantages and disadvantages for use in multi-institution testing...

From the literature it is evident that air recirculation has been used and is used for many different types of ventilated areas. For this reason there have been some large investigations into the advantages and disadvantages of using air re-... 

Bayesian probability theory and methods that are based on fuzzy-set theory. The principles of both theories are explained in Chapter 16 and Chapter 19, respectively. Both approaches have advantages and disadvantages for the use in expert systems and it must be emphasized that none of the methods, developed up to now are satisfactory [7,11]. 

The most frequently used methods of analyte isolation and concentration for organic compounds involve distillation, extraction auid adsorption techniques. Some typical applications of these techniques and their attendant -advantages and disadvantages for the analysis of trace organic solutes in water are summarized in Table 8.1 [4,26]. These methods will be elaborated on below and in subsequent sections of this chapter. 

Compare and contrast antimicrobials used for surgical prophylaxis and identify potential advantages and disadvantages for each antibiotic. 

Here, we describe the various alternatives to the use of E. coli expression hosts for heterologous gene expression. Advantages and disadvantages for the different expression systems are discussed, and practical aspects of expression technologies are also described. The feasibility of isotope labeling of recombinantly expressed proteins and their potential use for NMR is also discussed, since the costs and quantities of recombinant proteins produced depend on the system being used. 

What are the advantages and disadvantages of using softened steel for body panels on automobiles ... 

Research the aluminum-air battery, and the sodium-sulfur battery. Both are rechargeable batteries that have been used to power electric cars. In each case, describe the design of the battery, the half-reactions that occur at the electrodes, and the overall cell reaction. Also, describe the advantages and disadvantages of using the battery as a power source for a car. 

As with solids, colloids, and solutes, marine scientists have developed practical definitions of salinity that are based on measurement technique. Those in current use are listed in Table 3.2 with their typical measurement precision. Each method has its advantages and disadvantages. For example, refractometers are small, lightweight, and low cost, but have low precision, so they are used for field work in which only a rough... 

We close this section with a brief discussion of the advantages and disadvantages of using optically pure coordinatoclathrate hosts for photochemical... 

This section examines the advantages and disadvantages of using three-dimensional textile preforms, especially through-the-thickness stitches, as the reinforcements for composites. Their major mechanical properties are compared with those of conventional two-dimensional composites, such as strength, stiffness, interlaminar properties, impact resistance and tolerance, etc. Dransfield et al. (1994) have recently given a useful review on the improvement of interlaminar fracture toughness of stitched composites. 

Mention some of the advantages and disadvantages of using isolated enzymes rather than whole cells in biocatalysis. Is it always needed to purify enzymes for a biocatalytic application To what degree should one purify ... 

Although both polyclonal and monoclonal antibodies have been effectively used in immunochemical assays, only the latter can provide the high specificity required in some applications. Antibody specificity, on the other hand, is both a major advantage and disadvantage for immunochemical methods. It allows for highly selective detection of analytes but at the same time may complicate the development of multiresidue methods. Moreover, production of monoclonal antibodies requires special expertise and it is much more expensive than polyclonal antibodies. Thus, in cases where a range of analytes similar in molecular structure are required to be determined, a polyclonal may be more suitable than a monoclonal antibody. 

Synthetic Mixture Approach. Robert Neal has been the chief proponent of the synthetic mixture approach (2). The advantages and disadvantages of using synthetic mixtures of chemicals as surrogates for mixtures found in actual waters are the following ... 

For most of the columns listed in Table D 1.2.1, various dimensions are available for each of the column types. Generally, a column with an i.d. from 0.20 to 0.32 mm is regarded as a capillary column. A column with an i.d. of 0.45 or 0.53 mm is called a megabore column. Both capillary and megabore columns are commonly used in FAME analysis. There are advantages and disadvantages for both capillary and megabore columns. Capillary columns have better resolution but less sample capacity,... 

There are advantages and disadvantages to using different data sources. Primary data collection, in which data are collected solely for purposes of the project, are the best sources of data because the researcher can request and generate exactly the information that...
