\(y=\frac{1}{x}\) This means that the line y=0 is a horizontal asymptote. Horizontal asymptotes occur most often when the function is a fraction where the top remains positive, but the bottom goes to infinity. Going back to the previous example, \(y=\frac{1}{x}\) is a fraction.
Causes of Wounds. Wound causes can be internal or external in origin. Wounds of internal origin are mainly due to impaired circulation, neuropathy or medical illness. Wounds of external origin are due to an outside force or trauma that causes open or closed wounds.
1 A necrotizing subcutaneous infection can develop. This is a severe infection that can lead to gangrene, the loss and death of tissue.  Gas gangrene, a type of wet gangrene caused by the bacteria known as Clostridia, can occur from an open wound.
