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 |.
Magnetic declination or variation is the angle on the horizontal plane between magnetic north (the direction the north end of a compass needle points, corresponding to the direction of the Earth's magnetic field lines) and true north (the direction along a meridian towards the geographic North Pole).he magnetic declination in a given area may (most likely will) change slowly over time, possibly as little as 2â2.5 degrees every hundred years or so, depending upon how far from the magnetic poles it is. For a location closer to the pole like Ivujivik, the declination may change by 1 degree every three years.
