Shadow zone is an area where seismograph can not be detect earthquake after the seismic wave have passed through the earth. When earthquake strikes, seismic wave radiate out spherically from the earthquake's epicenter. At the angular distances of 104 degree to 140 degree from the earthquake focus, any direct P waves are not received.
Questions about bending over after Hip replacement. I just read in another thread a reminder of not bending over for 6 weeks after surgery. It has prompted this question. I guess I should ask the PT, but I'd also like input from folks who have been there. First, let me tell you about my job.
Hip Replacment Restrictions. An artificial hip joint cannot be bent to the extremes of its range. In every such instance, there is a chance that the surface may slip off and dislocate. So there are certain restrictions imposed on the type of activities that should not be done after hip replacement surgery. This restriction is very subjective depending on the type of artificial joint used, as well as the fine execution of the surgery.
