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.
After six weeks of progressively productive PT, I could bend my knee 115%. That was good news. However, 120% was ideal, so I had more work to do. As I write this today, the swelling remains in my knee, fifteen weeks post-surgery, but I am nearly able to create a natural bend. I figure that it will take another two months to achieve a pre-surgery bend. Not bad.
