Ceiling fan be used to reduce the stratification of warm air in a room by forcing it down to affect both occupants' sensations and thermostat readings, thereby improving climate control energy efficiency. Punkah-type ceiling fans date back to 500 BC, and are native to India. Unlike modern rotary fans, these punkah fans move air by moving to and fro, and were operated manually by cord. The first rotary ceiling fans appeared in the early 1860s and 1870s in the United States. At that time, they were not powered by any form of electric motor. Instead, a stream of running water was used,
Nasal reconstruction using a paramedian forehead flap comparison to the two stage flap, the three stage flap technique has shown better results, lower revision rates and more possibilities for use of skin grafts for lining. Most likely this is because of the reliable vascularisation of the three stage flap. Because of the flap’s rich perfusion, flap necrosis is unlikely to occur. If it happens the result of severe ischemia is normally caused by excessive tension on the flap, a misidentification of past injury, nearby scar formation, fanatic inset to the recipient site or exaggerated flap thinning. To solve the problem, to keep the underlying cartilage from infecting
