Critical double

This mathematical condition defines a critical separation in terms of a critical double layer thickness, k whidi can then be used to relate the critical salt concentration to the valence of the counterion. The result is the relation between the salt concentrations responsible for the CCC s being proportional to the counterion valences to the —6 power. 

Since zidovudine seems to be relatively well tolerated both in pregnancy and in neonates, there is also much reason to consider its use during lactation in order to reduce vertical transmission of HIV. Indeed, many would regard it as highly preferable to abandoning breastfeeding by HIV-infected women. In a critical double-blind West African study the effects of a 6-month course of treatment in prenatal and lactating... 

Material and method of well construction are both critical. Double cased monitoring wells using casing made of Teflon should be used whenever possible, and the intake part of the well should be made depth discrete Other requirements...

Synthetic efforts towards isochrysohermidin (1) commenced with exploration of the critical double inverse-electron-demand Diels- Alder union of 1,1,4,4-tetramethoxy-1,3-butadiene (28) with tetrazine 8, as shown in Scheme 6." After considerable experimentation, it was found that the desired sequence based on a double [4+2] cycloaddition reaction to produce the 1,2-diazine dimer 27 could be effected in 65 % yield upon treatment of 28 with... 

Like most high pressure joints, the double cone requires precision machined surfaces. In addition, proper bolt loads and tightening procedures are critical. Double cone gaskets can be used with either a bolted flat head or threaded closure type configuration. 

It has been shown that the principle of isomorphic critical behaviour accounts not only for the thermodynamic behaviour of mixtures near vapour-liquid critical points and near critical liquid-liquid mixing critical points, but also near special critical points, like azeotropic critical points, critical points where the critical temperature exhibits a maximum or a minimum as a function of temperature, re-entrant critical points and critical double points, depending on the values of the coefficients a,-, bi, and c,- in the expressions for the scaling fields. In this chapter we restrict ourselves to some more common cases of critical phase behaviour in mixtures.
