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.
When you bend your elbow, you can easily feel its tip, a bony prominence that extends from one of the lower arm bones (the ulna). That tip is called the olecranon (oh-lek'-rah-nun). It is positioned directly under the skin of the elbow, without much protection from muscles or other soft tissues. It can easily break if you experience a direct blow to the elbow or fall on a bent elbow. The olecranon is the bony point of the elbow.
