Bacteria were traditionally considered viable when they could be cultured, whereas today's viability concept tends to be alternatively based on the presence of some form of metabolic activity, a positive energy status, responsiveness, detection of RNA transcripts that tend to degrade rapidly after cell death, or of an intact membrane.
It also provides an opportunity to introduce urban youth to career opportunities that are traditionally not considered viable in their communities.
In the last decade substantial stocks have developed along the south coast (an area not traditionally considered commercially viable for rock lobster fishing).
While large media companies will not be marginalised by such activities, they could eventually notice a growing base of independent content providing would-be consumer-producers with a viable alternative to traditionally copyrighted material.
Several years ago, Daniel Cohn (left) and Leslie Bromberg took on the challenge of designing a low-emissions, fuel-efficient replacement for the polluting diesel engines traditionally viewed as the only viable option for powering heavy-duty trucks.
It is concluded that WSVE sets based on microstructure provide a viable practical alternative to the traditionally defined RVE in estimating the response of large polycrystalline microstructure datasets, with reasonable accuracy and significantly smaller computational resource needs.
The Net simply wasn't a viable alternative for distributing the signals traditionally sent over cables or beamed down from satellites.
Even if residents were more willing to share the downtown with nightlife, rapidly rising property values make clubs less and less financially viable in the areas where they traditionally flourished.
Nonetheless, the fact that significant and viable populations are maintained at roadsides suggests that traditionally managed roadside verges may allow long-term persistence of lizard orchid populations and may serve as refuges in a landscape context.
In addition, the U.S. has traditionally been quite nimble in transforming research discoveries into commercially viable products.
