Leprosy is also known as Hansen's disease after G. A. Hansen, who in 1878 identified the bacillus Mycobacterium leprae that causes the disease. The infection is characterized by abnormal changes of the skin.

1 As a very general estimate, installing gas line costs $20 to $30 per foot. 2  In some areas and circumstances, however, the price could be $75 per foot or more. 3  This price should include the costs of trench digging and all necessary permits, drawings, and inspections.
Electric stoves tend to carry the higher price tagânot by much, though. Whereas average electric stoves range from $650 to $2,800, comparable gas stoves range from $800 to $2,300. So thereâs a difference, but itâs not a very dramatic one. Operating costs, however, are often different enough to be a deciding factor for many.
