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. coordinate system.The grid convergence angle is also supplied when grid declination is selected.rid 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. coordinate system.
