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 |.
Grid declination. Grid Declination is defined as the angle of magnetic North relative to grid North where grid North is referenced to the grid lines shown on navigation charts with a Tranverse Mercator projection for a UTM coordinate system. The grid convergence angle is also supplied when grid declination is selected.
