1 Hernias that contain a loop of intestine without blood supply (strangulated hernias) require emergency surgery. 2  Hernias that contain a trapped loop of intestine (incarcerated hernias) need to be repaired as soon as possible to avoid strangulation.

The axis number on your prescription tells your optician in which direction they must position any cylindrical power in your lenses (required for people with astigmatism). This number shows the orientation or angle in degrees from 1 to 180. The number 90 means vertical position and 180 horizontal. A higher number for the axis does not mean that your prescription is stronger - it simply describes the position of the astigmatism.
The y-axis is vertical with values increasing from bottom to top. axis equal sets the aspect ratio so that the data units are the same in every direction. The aspect ratio of the x-, y-, and z-axis is adjusted automatically according to the range of data units in the x, y, and z directions. axis image is the same as axis equal except that the plot box fits tightly around the data. axis square makes the current axes region square (or cubed when three-dimensional). MATLAB adjusts the x-axis, y-axis, and z-axis so that they have equal lengths and adjusts the increments between data units accordingly.
