Plague is a rare but deadly bacterial infection causing fever, vomiting, seizures, organ failure, and more. Kawasaki disease is an uncommon inflammation of the blood vessels; the most common symptom is fever. Whooping cough, a contagious respiratory infection, causes a runny nose, a mild fever, and a severe cough.
In astronomy, declination (abbreviated dec; symbol Î´) is one of the two angles that locate a point on the celestial sphere in the equatorial coordinate system, the other being hour angle.eglecting atmospheric refraction, declination is always 0Â° at east and west points of the horizon. At the north point, it is 90Â° â | Ï |, and at the south point, â90Â° + | Ï |.
The Earthâs magnetic and geographic poles are in different places, and magnetic declination is the angular difference between the direction a compass needle points and the direction to the geographic North Pole. For most of the populated world, this angle is between zero and 30 degrees. Currently, Salt Lake City has a magnetic declination of about 12.5 degrees east (in other words, true north is 12.5 degrees west of the direction a compass needle points), but the angle has been getting smaller over time.
