1 Cyclothymic Disorder, or Cyclothymiaâ a mild form of bipolar disorder. 2  People with cyclothymia have episodes of hypomania as well as mild depression for at least 2 years. 3  However, the symptoms do not meet the diagnostic requirements for any other type of bipolar disorder.
Shorter rulers are convenient for keeping in a pocket. Longer rulers, e.g., 18 inches (45 cm) are necessary in some cases. Rigid wooden or plastic yardsticks, 1 yard long and meter sticks, 1 meter long, are also used.
However, you can change custom ruler units, and control where the major tick marks appear on a ruler. For example, if you change the custom ruler units for the vertical ruler to 12 points, a major ruler increment appears every 12 points (if such display is possible in the current magnification).
