Units and Definitions

Following is a listing of typical nomenclature expressed in SI and U.S. customary units. Specific definitions and units are stated at the place of application in this section. 

Since 1925, The International Commission on Radiation Units and Measurements at Bethesda, Maryland has been publishing reports updating the definitions and units for measurements of various radiation-related quantities. Of these ICRU Reports, special mention may be made of reports no. 19 (1971) [radiation quantities and units], 33 (1980) [radiation quantities and units], 36 (1983) [microdosimetry], 47 (1992) [thermoluminiscent dosimetry], and 51 (1993) [radiation protection dosimetry]. A succinct description of various devices used in dosimetry, such as ionization chambers, chemical and solid-state dosimeters, and personnel (pocket) dosimeters, will be found in Spinks and Woods (1990). In this section, we will only consider some chemical dosimeters in a little detail. For a survey of the field the reader is referred to Kase et at, (1985, 1987), McLaughlin (1982), and to the International Atomic Energy Agency (1977). Of the earlier publications, many useful information can still be gleaned from Hine and Brownell (1956), Holm and Berry (1970), and Shapiro (1972). 

A more detailed representation of the shock and bubble pulses than that of Fig 1 is shown in Fig 5 (taken from Ref 17). Definitions and units of the various phenomena illustrated are given in Table 1. These definitions will be needed in the immediate and subsequent discussions of underwater expins... 

We note that in other work, some of the frequency-independent factors appearing in the equation may be included in the definition of the spectral function, g(v). In such a case, the spectral function may be scaled relative to our definition and units may differ. 

Definitions and Units. Electrolytic conductivity is often defined as the electrical conductance of a unit cube of solution as measured between opposite faces. It is expressed in the same units as electrical conductivity, i.e.. reciprocal ohms per unit length. Most commonly wc find Mho/eemimeter (fU cm"1). siemens/cenlimeter IS cm 1), and siemcns/meler (S cnT1) ...

Definitions and Units of Model Parameters Used in the Benthic Bioaccumulation Model of Thomann (1991, 1992). 

Because the terms "soluble" and "insoluble" are relative, some textbooks give different definitions and units of concentration to describe them. Here are a few examples ...

Professor Oppenlander is well qualified to write about AOPs/AOTs, since he has contributed to this literature in a very significant manner. It is thus particularly valuable to see the application of incoherent excimer lamps covered so well, a subject that has been a central part of his research. Finally, it is good to see careful attention being made to consistent terms, definitions and units in accord with lUPAC recommendations. 

The peak current, in amps, at 25°C is given by the expression (37) (see appendix for symbol definitions and units). 

Prior to a more detailed description of these methods, it is appropriate at this point to provide definitions (and units of measurement) of the commonly employed terms in dynamic oscillatory analysis (16) ... 

The study of thermodynamics involves mechanical variables such as force, pressure, and work, and thermal variables such as temperature and energy. Over the years many definitions and units for each of these variables have been proposed for example, there are several values of the calorie, British thermal unit, and horsepower. Also, whole...

The theory of hydrodynamics similarly describes an ideal liquid behavior making use of the viscosity (see Sect 5.6). The viscosity is the property of a fluid (liquid or gas) by which it resists a change in shape. The word viscous derives from the Latin viscum, the term for the birdlime, the sticky substance made from mistletoe and used to catch birds. One calls the viscosity Newtonian, if the stress is directly proportional to the rate of strain and independent of the strain itself. The proportionality constant is the viscosity, q, as indicated in the center of Fig. 4.157. The definitions and units are listed, and a sketch for the viscous shear-effect between a stationary, lower and an upper, mobile plate is also reproduced in the figure. Schematically, the Newtonian viscosity is represented by the dashpot drawn in the upper left comer, to contrast the Hookean elastic spring in the upper right. 

Thus the fermentation model addressed is represented by a set of five differential equations and two algebraic equations. Table 5.1 provides the base values of the parameters used in this Z. mobilis fermentation problem (see all variables definitions and units in the Nomenclature section).
