Table 22.5 Burial rates of nitrogen Rates were calculated using several methods, assuming accretion has kept up with relative sea level rise (SLR), a budget of organic matter inputs and losses (OM budget), mass accretion rates using radiometric dating techniques ( Cs or Pb), or net particulate nitrogen (net PN) budgets to the marsh or in tidal creeks. GSW stands for Great Sippewissett Marsh...

In this case (Ma > 0,Ra < 0), under the condition of liquid thickness 4.6 mm, ethanol velocity 6.9 x 10 m s , and nitrogen rate 0.12 m h Marangoni convection was induced as shown in Fig. 8.6a in the form of parallel roll structure. When nitrogen rate was increased to 0.16 m h , the roll became finer and smaller as shown in Fig. 8.6b. 

In this case, two component, water and ethanol, was diffused to nitrogen in the liquid-gas concurrent flow and induced interfacial structure (Ma > 0, Ra> 0). Under the condition of liquid thickness 5.3 mm, aqueous ethanol rate 8.7 X 10 m s and nitrogen rate 0.1 m h the interface displayed clear cellular structure as shown in Fig. 8.7a. Under another condition of liquid thickness 4.3 mm, aqueous ethanol rate 1.1 X 10 m s and nitrogen rate 0.16 m h the cellular structure was not so clear and likely to have tendency of becoming roll as shown in Fig. 8.7b. Thus, the interfacial structure is also affected by the flowing condition of liquid and gas.

Further reports on the kinetics of multidentate-ligand substitution have appeared and it has been shown that the reaction of Ni + with (1) involves an initial and rate-determining bond formation to a pyridine nitrogen. Rate...
