I strongly suspect that when teachers face conditions such as pressure to meet arbitrary achievement goals, lack of planning time or little autonomy over curriculum, homework becomes an easy option to make up what could not be covered in class.
Excavation face conditions are presently determined and logged by manual visual investigation for most, if not all tunnel projects.
Among the boundary conditions discussed are: seepage face conditions for three-phase problems and multi-node constant-rate pumping wells.
For the High-realism mask and Real face conditions, responses are shown separately for Own-race (light grey) and Other-race (mid grey).
With comprehensive analysis on the mining and face conditions, the support intensity of the hydraulic support was determined as 1.4 MPa in Tashan coal mine.
Throughout the compounding, molding, and extrusion processes they are exposed to, POs face conditions that tend to degrade their polymer chains and change their properties.
An accurate machine prediction is dependent on rock mass and geological exploration conditions including rock strength, discontinuity conditions, hardness, underground water, poisonous gases, instability and mixed face conditions.
Results obtAssumedy using the present methodisplacemented with those obtained by using three-dimensional functionsements.
Fig. 4 Illustration showing (from left to right) author RJ in the Low-realism mask, High-realism mask and Real face conditions of Experiment 3, and the spatial arrangement of confederate and participants.
However, this advantage did not appear under the FACE conditions, likely because of various indirect effects of E-[CO2] on the physiology of the crop grown in open field conditions.
The resulting sub-surface conditions can be very onerous for tunnelling, with tunnel drives commonly encountering a significant proportion of mixed face conditions, comprising partly rock and partly soil.
