thuringiensis strains have unswollen
and ellipsoidal spores that lie in the subterminal position.
Those sperm cell which showed swollen, coiled tail and unstained head represent intact plasma membrane integrity, while those with unswollen
, uncoiled tail and pink head showed inactive sperm plasma membrane integrity.
where [W.sub.1] and [W.sub.2] represent the weights of unswollen
and swollen test specimens, respectively.
The volumetric swelling was characterized by the usual experimental volumetric swelling extent parameter, the volumetric ratio [Q.sub.exp], defined as the final swollen volume (or swollen bed height after the second swelling step) divided by the initial unswollen
volume (or initial dry bed height) (see ).
4C), with no side more severely swollen than the other, although the entire column (both swollen and unswollen
portions) is somewhat compacted perpendicular to its long axis (Fig.
Clear heads and tails and swollen tails indicated intact biochemically active sperm membranes while pink heads and unswollen
tails indicated disrupted inactive sperm membranes (Tartaglione and Ritta 2004).
Clear heads and tails and swollen tails were indicated intact, biochemically active sperm membranes, while pink heads and tails and unswollen
tails were indicated disrupted, inactive sperm membranes.
We did our own shotgun loading in South Africa, and even after the big day where everybody shot several cases, our thumbs emerged unscathed and unswollen
& not unmoving, unswollen
array as just one more production
Reproductive condition of adult females was characterized as pregnant (estimated by palpation of the abdomen), lactating (swollen pink nipples), post-lactating (unswollen
, bare nipples), or nonpregnant (unswollen
, furred nipples; Racey 1988).
where D is the weight of the unswollen
sample; F is the weight fraction of the insoluble non-rubber ingredients; T is the original dry weight of the sample; [A.sub.0] is the weight of solvent absorbed; Or is the density of the rubber (density value is 910 kg/[m.sup.3]); and [[rho].sub.s] is the density of the solvent (density value is 870 kg/[m.sup.3]).
2a-2c Poisson's ratio was assumed to be 0.5, as in an incompressible solid, and a suitable value of [G.sub.0], the strain energy release rate in the unswollen
polymer, was taken as 0.3 kJ/[m.sup.2] (typical of epoxy and other polymers) from the literature.
