Lumbar spondylosis is a spine condition that describes the natural deterioration of the lower spine due to age and compression. While spondylosis can occur throughout the spine, the most common location of occurrence is in the lowest portion of the spine, where the lumbar spine meets the sacrum, or tailbone.
A point {lat,lon} is a distance d out on the tc radial from point 1 if: 1  lat=asin(sin(lat1)*cos(d)+cos(lat1)*sin(d)*cos(tc)) IF (cos(lat)=0) lon=lon1 // endpoint a pole ELSE lon=mod(lon1-asin(sin(tc)*sin(d)/cos(lat))+pi,2*pi)-pi ENDIF.
Given a datetime, calculate the lat/lon coordinates where the sun is directly overhead. up vote 0 down vote favorite. 1. Some variants of this question have been asked before, but not this exact one.ongitude will depend on the time of the day. Normalize time so that one day = 360 degrees and offset accordingly. Details: AT present tropic of cancer is at latitude L = 23Â° 26â² 16â³. So, Latitude = L*cos((X-a)/b), where a=June21st, b = 365.25/2pi.
