An adjustment to the speaker impedances enables higher output power to various speakers of different impedance. In a conventional amplifier which is designed for 4 ohm speaker impedance, the output power will drop sharply when using 6 or 8 ohms.
BACKGROUND AND AIMS: Hirschsprung disease is considered to be curable when performing definitive surgery. However, the postoperative bowel function is not always satisfactory. The long-term postoperative function of bowel evacuation and the quality of life of such patients are considered to be important.ACKGROUND AND AIMS: Hirschsprung disease is considered to be curable when performing definitive surgery.

Hirschsprung's disease or Hirschsprung disease (HD), also called congenital megacolon or congenital aganglionic megacolon, is a form of megacolon that occurs when part or all of the large intestine or antecedent parts of the gastrointestinal tract have no ganglion cells and therefore cannot function.ypically, Hirschsprung's disease is diagnosed shortly after birth, although it may develop well into adulthood, because of the presence of megacolon, or because the baby fails to pass the first stool (meconium) within 48 hours of delivery.
