These fluctuations are almost all under 1, which is a good indicator that the remaining 80% of the content has limited contribution to the traffic.
Consequently, they make a greater contribution to road traffic injury (Bhalla et al. 2007), air pollution and transport greenhouse gas emissions (André and Rapone 2009), noise (Hänninen and Knol 2011), and stress (Jansen et al. 2003) than other kinds of light vehicle trips.
Insufficient roadway sight distance (SD) may become a contribution factor to traffic collisions or other unsafe traffic maneuvers.
Therefore, the importance of LprG in virulence could be due to its contribution to assembly, trafficking, and cell wall insertion of glycolipids.
Cars are one of the top contributors to greenhouse gas emissions globally, and cars in cities can be especially heavy with their contributions, owing to traffic and population density.
Where school commutes are made by private cars there can be a significant contribution to early morning traffic congestion and associated externalities, as well as missed opportunities in regards to benefits that would accrue from higher occupancy and non-motorised modes of travel.
The larger local contribution to NO2 by traffic and oil burning, on the other hand, results in greater overall spatial variation.
Therefore, further investigations will be necessary to fully delineate the role of LFA-1 and its ligands ICAM-1 and ICAM-2 beyond their mere contribution to T cell trafficking across the BBB.
We estimated no local traffic contribution for SO2 because there is virtually no traffic contribution to this pollutant.
In our investigation, estimated concentrations of PM10 at the 7 monitoring stations recording PM10 in the study area were 24.4%% of the measured values, a value very similar to that estimated as contribution of traffic to measured environmental levels of PM10 or its major component PM2.5 in recent studies in Milan (27.1 and 17 24 %, respectively) [ 39, 40].
For instance, WSJ.com gets about a quarter of its traffic from Google, all told, and former Business Weekcom editor John Byrne pegs Google's traffic contribution to BW.com at 45 peditor, "up from less than 20% in 2006".
