Measurement of antinuclear antibodies (ANAs) in serum is the most commonly performed screening test for patients suspected of having a systemic rheumatic disease, also referred to as connective tissue disease.(1) ANAs occur in patients with a variety of autoimmune diseases, both systemic and organ-specific.
How do you rotate a figure 180 degrees in anticlockwise or clockwise direction on a graph? Rotation of a point through 180Â°, about the origin when a point M (h, k) is rotated about the origin O through 180Â° in anticlockwise or clockwise direction, it takes the new position M' (-h, -k).Worked-out examples on 180 degree rotation about the origin:n plotting the points P (-3, 1) and Q (2, 3) on the graph paper to get the line segment PQ. Now rotate PQ through 180Â° about the origin O in anticlockwise direction, the new position of points P and Q is: P (-3, 1) â P' (3, -1). Q (2, 3) â Q' (-2, -3). Thus, the new position of line segment PQ is P'Q'.
Read your map bearing from the compass dial. Make sure the bearing agrees with your direction of travel â for example, if you intend to travel due east, the bearing is 90 degrees, not 270 degrees. E). : If the local declination is positive, then subtract the declination amount from the bearing you just derived.) Place the compass on the map so the baseplate is parallel to the line you drew. Make sure the direction of travel arrow points to your destination. E) Rotate the dial until compass ring north agrees with map north. Do not move the compass when you rotate the dial.
