Values of Db determined by " Th profiles commonly range from 1 to 50 cm7y in estuarine and slope sediments (Aller and Cochran 1976 Aller et al. 1980 Sun et al. 1994 Gerino et al. 1998 Green et al. 2002) to < 10 cm7y in the deep sea (Aller and DeMaster 1984 Pope et al. 1996). Although there is some overlap, mixing rates in the deep sea tend to be lower than those in nearshore sediments. This trend has been documented with °Pb profiles as well (e.g., Henderson et al. 1999). [Pg.484]

The chemical behavior of U and its daughter nuclides in the ocean environment was extensively studied in the 1960s and 1970s and has been well summarized (Cochran 1992). The most important mechanism by which nuclides are separated from one another to create disequilibrium is their differing solubility. For U, this solubility is in turn influenced by the redox state. The process of alpha-recoil can also play an important role in producing disequilibrium. [Pg.496]

As discussed elsewhere in this volume, another field where the use of U-series disequilibria has proven to be very useful is the study of chemical transport in waters, either marine (see Cochran and Masque 2003 Henderson and Anderson 2003), estuarine (Swarzenski et al. 2003) or continental waters. In the continental domain, in addition to characterization of transfer processes related to groundwater flows (Porcelli and Swarzenski 2003), radioactive disequilibria have also helped in constraining chemical exchanges between particulate, dissolved and colloidal loads of waters, as well as the origin of chemical fluxes carried by waters. [Pg.553]

At the RDE the velocity profile obtained by Karman and Cochran (see ref. 124) and depicted in Fig. 3.68a leads via solution of its differential convection-diffusion equation to the well known Levich equation ... [Pg.205]

Gibaldi et al. [45] postulated that convective forces may be present in the GI tract during in vivo dissolution. This study took advantage of the well-defined hydrodynamics of the rotating disk, incorporating the solutions for the velocity profile and transport equations of Cochran [50] and Levich [51] to obtain... [Pg.143]

Cochrane methodology reviews As well as Cochrane Reviews of the effects of healthcare interventions, there are also Cochrane methodology reviews of the ways in which health care can be evaluated and, from 2006, there will be Cochrane Reviews of the accuracy of diagnostic tests. [Pg.26]

It is well known that both glomerular and tubular renal functions decline with age in at least one third of individuals. As a result there is greater variation in renal function in older subjects. Glomerular filtration rate can be predicted by creatinine clearance, which can be estimated based on measured serum creatinine (Sercr) concentration. One such formula is the Cochrane and Gault formula in which... [Pg.207]

Sayre (1952) discovered an equality relation between all the structure amplitudes, or between all those in one zone, for a structure of equal atoms, well resolved from each other. In itself it is not easy to apply, since it involves so many terms but on the basis of this work Cochran (1952) concluded that the following simple relation between the signs of three terms (s(hki) stands for the sign of hkl) is probably true if the... [Pg.430]
