Lost Circulation and overflow often occur concurrently in fracture formation due to gravity displacement, causing a downhole complexity, out of control for blowout, reservoir damage, well control difficulty, drilling cycle prolonging and cost overrun.
This means that the damped cantilever looses its oscillation energy after only a few (≈Q′ / 2π) oscillations, but it is still underdamped (Q′>1/2), i.e. abrupt displacements cause an overshooting.
Violence and mass displacement caused by a four-year civil war have taken a heavy toll on food production in CAR and a recent influx of refugees and extreme weather events have left Chad desperately food insecure.
However, the displacement caused by a force normal to the surface involves an additional parameter, i.e. the ratio of specific surface stress to shear modulus.
Three years after Russian forces poured into Chechnya to crush the republic's separatist government, President Vladimir V. Putin's government appears determined to rid itself of the most visible sign of the large-scale displacement caused by a war that has not yet ended: the tent camps here in the neighboring republic of Ingushetia.
The two sources of information are complementary: environmental information gives direct information regarding location relative to the environment, whereas self-motion information can be used to update the estimate of environmental location (spatial updating), or to estimate the displacement caused by a recent movement (path integration).
It also provides a reasonable prediction of slope displacement caused by an earthquake.
Already in Nigeria, the population displacement caused by an encroaching desert is stirring up conflict between Christians and Muslims.
Actually, after CT scan assessment revealed intraforaminal rib displacement causing cord compression, a careful re-evaluation of pre-operative MRI permitted us to evidence this complication (Fig. 2b).
Real surfaces are often stiff, meaning they can be modelled more accurately by a spring constant that increases with displacement, causing reduced duration and a brighter excitation, as shown in Figure 5.
