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, sometimes called magnetic variation, is the angle between magnetic north and true north. Declination is positive east of true north and negative when west.Magnetic declination changes over time and with location.As the compass points with local magnetic fields, declination value is needed to obtain true north.. more.eclination is positive east of true north and negative when west.
