A procedure for measuring the acoustic scattering matrix coefficients of a duct discontinuity for higher order acoustic duct mode propagation conditions is described and tested. The technique requires measurement of pressure waves per mode coming in and out of the discontinuity. Assuming N cut-on modes, the 2N 2 scattering matrix coefficients are determined after repeating the experiment for N ...

Persistent omphalomesenteric duct is a rare congenital anomaly and protrusion of the bowel through the duct is the only neonatal emergent clinical entity associated with this condition. The pathogenesis is the lack of intestinal involution by the ninth gestational week. There are several associated anomalies like intestinal malrotation, oesophageal atresia and omphalocele, which are all extreme...

Background: Intraductal papillary neoplasm of the bile duct (IPNB) is a specific entity for which there has been no classification that correlates clinical presentation with patient survival. We, therefore, propose a new classification based on radio-pathological appearance correlated with clinical findings including outcome. Methods: We retrospectively reviewed the medical and pathological rec...

I Have 110 intention of attempting any exhaustive study of the subject of jaundice ; I merely offer some remarks on the subject as seen solely from the surgical point of view. Thus I deliberately exclude from consideration all cases of jaundice due to any ?ause which may be roughly called medical, as well as any consideration of the pathological aspects, lriteresting though they are. When a cas...

Abstract: The duct model used here is that Kahan and Eckart [1950]. The source of the electromagnetic field is taken to a vertical magnetic dipole in the upper surface layer, with an arbitrary time – varying moment, we can determine the transient behavior of the electric field strength at any distance above the duct .The paper presents a method which allows the calculation of the atmospheric di...

Endoscopic manometry was used to measure pancreatic duct, common bile duct, pancreatic duct sphincter and bile duct sphincter pressures in 43 healthy volunteers and 162 patients with a variety of papillary, pancreatic and biliary disorders. Common bile duct pressure was significantly raised after cholecystectomy, with common bile duct stones and papillary stenosis but pancreatic duct pressure o...

Pancreas is an exocrine and endocrine organ. Exocrine portion secretes digestive fluid. Endocrine secreting insulin glucagon etc. developed from dorsal ventral pancreatic buds, which arise either side of distal foregut. When duodenum rotates to right, bud(VPB) posterior along with common bile duct(CBD) finally lies below behind the bud(DPB). In humans, DPB forms major part VPB inferior head unc...

An experimental investigation is conducted to determine the effect of repeated-plate blockages of variable streamwise spacing on heat transfer characteristics of turbulent flow in rectangular ducts. The plates are attached to the upper and lower walls in a staggered arrangement. The experiments are carried out by mass transfer and the analogy between heat and mass transfer provides the necessar...
