In a petroleum crisis, individuals have choices: mass transit, car pooling or even walking.
Early CTP parameters (<72 hours of SAH) were not predictive of DCI, but an increased mean transit time (pooled mean difference, 1.5 seconds; 95% CI, 0.9 to 2.2) or decreased CBF (difference, −11.9 ml/100 g/minute; 95% CI, −15.2 to −8.6) in the CTP performed between day 4 and day 14 was diagnostic for DCI [ 41, 44, 46– 546.
As in other organs, these progenitors can reside as transit-amplifying pools, by which lineage-biased progenitors expand to replenish discrete mature phenotypes.
The amount of time fish spent in a certain cell of the pool (transit time) was measured and related to hydraulic conditions.
As proHNPs are primarily secreted from myelocytes, the last precursor stage in the mitotic pool, transit time through the postmitotic pool would be a fair initial estimate of the time from start of rise of proHNPs until neutrophil appearance in circulation.
Those who commute to work using mass transit or van pools are eligible for the same amount in employer-provided pretax commuter benefits this year as their colleagues who drive and park, thanks to the fiscal package passed by Congress this week.
Based on that data, a company may offer incentives for mass transit or car pooling.
While multistage models for a detailed description of differentiation have been developed [ 21], we lump different stages of cell types within the transit-amplifying progenitor pool into one population, avoiding excess numbers of unmeasurable parameters.
In areas not well served by mass transit, demand for car pools, van pools, shuttles and park-and-ride lots has soared and is still building, according to transportation agencies that provide the services.
"There are more and more incentives being put in place," marvels Lowell Ungar, director of policy for the Alliance to Save Energy in Washington, D.C. Plus, old standbys, such as the tax break for taking mass transit or a van pool to work, have been growing.
