Alam, another food cart operator in the Soho area, says more expensive alternatives are unviable: after all, the food's selling-point is its cheapness.
Joanna Killian, chair of the Society of Local Authority Chief Executives and Senior Managers, said: "This settlement will increase the risk of more councils being financially unviable … very difficult local choices will now need to be made and local government should have the freedom to make these choices, even when setting council tax".
The greater the erosion of assets, the greater the level of vulnerability - poor herders are more likely to end up with an unviable herd size than wealthier herders, even when they lose the same relative amount of livestock (Rass [2006]).
If several barriers are in place, an uninfected cell must acquire a specific set of mutations under constraints imposed by those barriers that are still intact (e.g., apoptosis and cell cycle arrest in response to mutation or restrictions of the total number of divisions imposed by regulation of telomerase) without acquiring the vastly more common mutations that make the cells unviable.
Line-catching is more ethical but it's becoming an increasingly unviable way to make a living, says Peter Williams, who fishes out of Emsworth and will be supplying the Chichester Catchbox scheme.
"Even our next phase of expansion, which will see SAIL's annual capacity increasing to 24 million tonnes from the present 14 million tonnes, would be unviable unless we have access to more captive mines," says Verma.
The second reason derives from a simple observation that reduces the number of genotypes whose viability needs to be determined even more dramatically: Removal of a reaction from an unviable metabolism cannot result in a viable metabolism.
Tobacco leaf degrades the soil of more nutrients than many other crops, often making soil unviable to grow food essentials.
While the successful freezing of human semen and embryos had been possible for decades, eggs proved much more fragile, prone to forming ice crystals that rendered them unviable.
