The AA said a thorough review of yellow line restrictions was needed to ensure they do not "run out of control".
We find that days with line restrictions (DLRs) look set to increase by up to 1170%, to as many as 84 120 per year, by 2100 in a high sea-level rise scenario (0.55 0.81 m).
Increased costs to the railway industry deriving from maintenance and line restrictions will be small (£ millions) in comparison with damage caused by individual extreme events (£10s of millions), while the costs of diversion of the railway are higher still (£100s of millions to billions).
More than two decades ago, state voters approved hard-line restrictions against giving public assistance to immigrants living here illegally.
The risk, of course, is making the flow worse by removing line restrictions provided by the destroyed riser, but isolates the leak to one source that could be then controlled.
However, we also propose that early-acting deterministic mechanisms evolved repeatedly to accelerate germ line restriction, not to protect inherent properties of the germ line.
These observations suggest that early germ line restriction is an innovation of rodents that develop extra-embryonic tissues (such as ExE) producing germ line-inducing signals.
It is in this light that we postulate that early germ line restriction by Blimp1, 'Blimping', evolved in rodents and enhanced evolvability.
Germ line restriction occurs, in part, because Blimp1 represses expression of a number of genes involved in somatic development (Ohinata et al., 2005; Kurimoto et al., 2008).
However, current data suggests that early germ line restriction has evolved in mammals as well, and therefore precocious germ line commitment by determinants has evolved independently in every order of vertebrates.
