Recent improvements in fiber properties combined with their broadband acoustic dissipation characteristics make such materials potentially desirable for implementation in silencers. The acoustic modelling of simple silencer geometries, such as circular or rectangular cross-sections, has been established and classified depending on the assumption of locallyor bulk-reacting lining. Morse [1] used...

Background: The current advance in liver anatomy and surgery is based on the new concept of subdivision. The area fed by each tertiary branch was cone-shaped unit and the cone unit resection indicated resection on segments smaller than Couinaud’s segments. Material and methods: Portobiliary casts were obtained from 27 out of 30 cadaveric liver specimens, using injection-corrosive method. Under ...

mullerian duct anomalies (mdas) are relatively common disorders that are particularly responsible for obstetrical complications and have a prevalence of about 3%-4% in the general population (1, 2). uterine malformations may result from arrested development of the mullerian ducts, failure of fusion of the mullerian ducts or failure of resorption of the median septum (1, 2).

Histological and histochemical studies on the pancreas of goose (Anser albifrons) were carried out using special staining and light microscope. The pancreas in goose is serous tubuloacinar gland having exocrine and endocrine part. Smooth muscle fibres were absent in capsule of pancreas. Acinar cells have bizonal shape. Intralobular ducts, Interlobular and main excretory ducts were present withi...

In the development of the human biliary system, the extrahepatic bile ducts (EHBD) develop from the embryonic hepatic diverticulum, while the intrahepatic bile ducts (IHBD) originate within the liver from the ductal plate. The ductal plate is a flat muralium of primitive biliary epithelium that develops in the mesenchyme along the branches of the portal vein, by a process which requires a delic...
