viability

While temporary halts are common in vaccine trials, the interruption to the closely watched Astra-Oxford study had raised concerns about the viability of one of the fastest-moving experimental shots seeking protection from the pandemic.

Last week, though, construction started on the ITER fusion plant in France, which hopes to prove the commercial viability of fusion power.

To test the viability of their pollen-loaded bubbles, the researchers used this technique to pollinate by hand pear trees in an orchard.

Competition among larv was found to be the chief factor in viability.

Careful handling of the nuts is advisable to preserve their viability.

If the viability of the pollen falls below 50% they consider it unsatisfactory.

Chestnuts, beechnuts and acorns require more care when they are to be stored, for their viability is very sensitive to dryness.

Its viability has always been very poor; in this respect it is one of the very poorest of the sex-linked characters.

Seeds retain their viability or germ developing power, a given number of years and are then useless.

Sodium chloride, in the absence of hypochlorites, was found to have no influence upon the viability of B. coli in water.
