Technology recommendation

Environmental Science Technology recommends fewer than 20 references, while Analytical Chemistry specifies no more than 50. 

In the literature, emittance and emissivity are often used interchangeably. NIST (the National Institute of Standards and Technology) recommends use of the suffix -ivity for pure materials with optically smooth surfaces, and -ance for rough and contaminated surfaces. Most real engineering materials fall into the latter category. 

FMC Technologies recommends that to obtain a uniform material flow pattern, the ratio of the throat (T) to the hopper gate height H) be 0.6 for an ideal hopper design. The material at the front and the rear of the hopper will then move at nearly the same velocity. An acceptable design may be obtained if the ratio of T/H is between 0.5 and 1.0 however, a ratio outside these limits may distort the material flow patterns and reduce the feed rates (FMC Technologies, 2000). See Figure 18.18. 

Indeed a recent report to the National Science Foundation on Protein Resources and Technology recommends the study of the modification of the functionality of oilseeds and legume proteins by physical, chemical, and enzymatic methods to facilitate development of protein materials with wide versatility and acceptability in formulated foods (I). 

Anion exchange for arsenic removai is one of the BAT (best available technology) recommended by the U.S. Environmental Protection Agency (EPA). Extensive studies, both at the bench and pilot scale have shown that for a source water containing <120 mg/L sulfate and <500 mg/L TDS, ion exchange may be the arsenic-removal process of choice (3,4,19-21).

There are special sections which deal with different production and processing technologies. Recommendations for each target application of a coating system are provided. Finally, special treatment of state-of-the-art paint testing, analysis, environmental protection, recycling, and toxicology is offered. 

Another way of facilitating the incorporation of flame-retardants into a polymer system is to encapsulate liquid agents, forming powder-like products (with an average particle size of about 30 jum), such as Phoenix ISO-2 A and ISO-2 B of Insulated Technologies, recommended for polyurethane and styrenic foams. ...

The following table lists values of fundamental physical constants used in thermodynamic calculations. Except for those marked exact, they are the 2006 CODATA (Committee on Data for Science and Technology) recommended values. The number in parentheses at the end of a value is the standard deviation uncertainty in the right-most digits of the value. 

In parentheses are given the technologically recommended concentrations. Source Refs. 1-10.
