\(y=\frac{1}{x}\) 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.
Puncture wounds are caused by a sharp object, such as a nail, that penetrates skin layers and leaves behind a piercing in the skin. These wounds are prone to infection, as bacteria can be driven deep inside skin, and can be difficult to clean thoroughly.uncture wounds are caused by a sharp object, such as a nail, that penetrates skin layers and leaves behind a piercing in the skin.
