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 |.
Magnetic Declination. The angular difference between the geographic and the magnetic meridians at a point on the earth is called magnetic declination. The values for magnetic declination in Wisconsin vary today from -4.0Â° in Door County to +1.5Â° in the west-central part of the state.o correct a magnetic compass reading to true north when west of the 0Â° line, the declination value should be subtracted from the magnetic north reading. When east of the 0Â° line, you should also subtract the declination from the magnetic north reading, but remember that in this case the declination value is negative.
