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 replacement. A hip replacement is a common type of surgery where a damaged hip joint is replaced with an artificial one (known as a prosthesis). Adults of any age can be considered for a hip replacement, although most are carried out on people between the ages of 60 and 80. A modern artificial hip joint is designed to last for at least 15 years.
