Briggs method

Briggs method does not give explicit information on surface conduction. Two modem methods of determining the zeta potential and the surface conductivity will be summarized below. 

The use of the methods of Briggs to estimate plume rise are relied on in the SCREEN model. Stack tip downwash is estimated following Briggs (1973, p.4) for all sources except those employing the Schulman-Scire downwash algorithm. Buoyancy flux for non-flare point sources is calculated from ... 

This calculation method uses the same Pasquill-Gifford dispersion parameters as the Pasquill-Gifford-Briggs calculation method. Therefore, the dispersion parameters Oy and for this method may be obtained from Figures 6(a) and 6(b) respectively.

A more convenient method of preparation is described by Briggs, according to which, the eobaltous carbonate is dissolved in the smallest possible quantity of nitric acid, the solution poured into aqueous ammonia containing ammonium carbonate, and air drawn through the liquid for some time. It is then heated on a water-bath with frequent additions of ammonium carbonate, when the colour of the liquid changes to deep red, and allowed to stand till crystallisation is complete. The water of hydration is not removed on heating to 100° C., nor in vacuo over sulphuric acid at ordinary temperature.3...

In the discussion of both the hyperspherical method and the molecular orbital method we assumed that the motion in the Rb or R direction was slow. While in the Born-Oppenheimer approximation the slowness is generally thought to arise from the much higher mass of the nucleii, as pointed out by Feagin and Briggs,22 it is probably the repulsive nature of the internuclear potential which allows the separability. In other words, the success of these methods in treating He is due to the interelectronic repusion of the l/r12 potential. 

For most enzymes, the rate of reaction can be described by the Michaelis-Menten equation which was originally derived in 1913 by Michaelis and MENTEN 21 . Its derivation can be achieved by making one of two assumptions, one of which is a special case of the more general Briggs-Haldane scheme, whilst the alternative is the rapid-equilibrium method given in Appendix 5.3(2 ). 

The surface extended X-ray absorption fine structure (SEXAFS) method can use either an electron or an ion detection signal (Koningsberger and Prins, 1988). The classification of analytical techniques may be considered in terms of incident and emitted radiation, resolution, and sensitivity, according to Table 4.7, which lists eight of the many possible techniques (Briggs and Seah, 1990 Buckley, 1981 Watts, 1990). Many of the surface analysis techniques were introduced into many laboratories over the years of 1968 to 1970. This resulted from the maturing of clean vacuum systems which could achieve pressures, down to 10"8 Pa. At these low pressures, it is possible to obtain and maintain atomically clean surfaces.
