The upward motion induced by flow impingement influences plume height in front of the obstacles, while behind them the downward motion related to flow reattachment to the ground largely affects the vertical spread and average height of plume.
But getting a job does not mean that all the obstacles are behind you.
At a February campaign event, Pastor Willie James Campbell of St. James Ministries, a Jackson supporter, said that "Satanic forces" were behind the obstacles to the incumbent congressman's re-election and that Halvorson's agenda represents a "political demonic force".
The hazard-identification cameras, both front and back, focused not only on the obstacles in front of them and behind but also gave a view of the vehicle itself.
Working under heavy fire, the engineers set about their task of clearing gaps through the beach obstacles work made more difficult by loss of equipment, and by infantry passing through or taking cover behind the obstacles they were trying to blow.
Wherever you think your enemies will attack from, you should put obstacles there, so you can take cover behind the obstacles.
Why should I try to get a good job when the deck is stacked against me?" You can say, "I don't have a college degree, so employers won't hire me -- they're idiots!" You can hide behind the obstacle that you created for yourself.
Finally, in steps in which the contralesional forelimb was leading the crossing manoeuvre with success (Fig. 6C) as in steps in which the ipsilesional forelimb was leading (not shown), the trailed forelimb was placed farther behind the obstacle as compared to limb position before lesion, at least within the acute post-lesion period.
During a silent trial, we placed an empty cage 1.5 m behind the obstacle as a control [23], [33], moved the confined bats 35 m away, and waited 2 min before starting the trial to minimize residual activity in the experimental area elicited by the trapped bats [34].
Some systems, either independently or in conjunction with a camera, provide alerts about obstacles behind the vehicle.
This would cause an errant vehicle entering the unprotected zone to be "trapped", with no possibility to retain control and crash into roadside obstacles behind the barriers.
