Surgery in $M \times N$ with $\pi _1 M \ne 1$

Abstract

The case m -2k appears to be easier to handle, since the obstruction is the intersection form, which is just the ®-product of the form on M and the form on N, and is homologically defined. The self intersection form does introduce a complication, at least if k is odd. In any case we concentrate here on m = 2k + l.

Estimation of the degree of binding of tetracyclines in human plasma

“…The pH of the buffer is critical since the degree of binding is known to vary with pH * Correspondence. (Williamson, 1969), this may also account for some of the variation in previously determined values (Table l), consequently the buffer used was at physiological pH since calcium citrated-plasma was used, Caz+ variations were not considered likely to affect the results. Preliminary studies showed that, with shaking, equilibrium was achieved between 48 and 72 h and that no dilution of the plasma occured and that the pH at equilibrium was 7.4.…”

Product formulas for $L_n \left( \pi \right)$

“…I(a)=0 if m^O (mod 4) and 1(a) = Index P for any PGa if m = 0 (mod 4), in which case the index of P is the index of the quadratic form (x\Jy) [P] on H m/2 (P; Q). Williamson [8] has shown that for n odd and m even, PROOF. Let P be a simply-connected representative of a.…”
