A typical field case in a chinese coal mine demonstrates that the mining abutment stress can strengthen the relative displacement along the weak plane for the entry roof.
A sensitivity study is presented that demonstrates the most important parameters to be the damage state and repair quantities related to the foundations and abutments.
The accuracy of computer-assisted design and computer-assisted manufacturing (CAD/CAM) screw channel drilling guide for locating the abutment screw has not been demonstrated.
Studies of the overactive detrusor ultrastructure demonstrated the existence of ultraclose abutments and protrusion junctions [ 32].
Through extensive nonlinear time-history analyses conducted using three suites of ground motions, it is demonstrated that demand parameters for skew-abutment bridges, such as deck rotation and column drift ratio, are higher than those for straight bridges.
We demonstrate a method for conceptual design of bridges with skewed abutments aiming at uniform performance (i.e., tolerable loss) objectives.
A combination of nonlinear link elements has been demonstrated to model very accurately the complex hysteretic response due to abutment-soil interaction and of the shear keys in SAP2000 resulting in reliable results as discussed in detail earlier.
It demonstrated that the horizontal deformation rate of the top coal and roof caused by abutment pressure in front of the coal wall was much less than the vertical subsidence rate of the top coal and roof at rear of coal wall.
Complementary to these factors, several studies have demonstrated a second discrete inflammatory cell infiltrate, additionally to the connective tissue lateral to the abutment fixture junction [ 5, 12, 13].
In addition, a parametric study is performed and demonstrated that the behavior of IABs is affected by temperature loadings, boundary support types, backfills behind abutments, soils surrounding piles, and pile bent connections.
Fig. 16 Another ZIP flap case demonstrating the use of a perforated polythene "washer" to keep the flap from overgrowing the implant abutments during the healing phase Fig. 17 The appearance of the case shown in Fig. 16 with the polythene "washer" removed at 2 weeks post-surgery, providing access to the zygomatic oncology implants.
