A subdural hematoma is usually the result of a serious head injury. When it occurs this way, it is called an acute subdural hematoma. Acute subdural hematomas are among the deadliest of all head injuries. The bleeding fills the brain area very rapidly, compressing brain tissue.
Mitering Inside Corners. 1  1. Measure the angle of the corner. 2  2. Set a compound miter saw with the correct angles. 3  3. Cut the right inside corner.  4. Set the miter saw angle 1  again. 5. Cut the left inside corner.  6. Fit the two pieces together before nailing them in place.
Before cutting, measure twice and test-cut the angles on scrap pieces of molding. When working on corners, measure the length needed to cut the shortest side of the molding. The top of the molding will be shorter for an inside corner; the bottom of the molding will be shorter for an outside corner. Measure again before making the final cut [source: Louisiana Pacific]. If two pieces are fairly close to fitting together, acrylic caulk can be used to fill the gap.
