Intraductal papillary mucinous neoplasms (IPMNs) are mucin-producing papillary neoplasms of the pancreatic or biliary ductal system that exhibit variable cellular atypia and cause ductal dilation. There are few reported cases of IPMN arising from the biliary tree in the literature. It has a higher propensity to undergo malignant transformation compared to IPMN arising from the pancreatic duct. ...

This study is concerned with the numerical analysis, formulation, programming and computation of steady, 3D conservation equations of reacting laminar flow heat and mass transfer in ducts of arbitrary cross-sections. The non-orthogonal boundary-fitted coordinate transformation method is applied to the Cartesian form of overall-continuity, momenta, energy and species-continuity equations, parabo...

A 32-year-old male, a known case of alcohol related chronic non calcific pancreatitis, was referred to us for pancreatic endotherapy for relief of intractable abdominal pain. The cross sectional imaging studies had revealed an irregularly dilated main pancreatic duct. The examination of the major duodenal papilla revealed the presence of two separate orifices at endoscopic retrograde cholangiop...

The estimation of optimal support boundaries under the monotonicity constraint is relatively unexplored and still in full development. This article examines a new extreme-value based model which provides a valid alternative for completely envelopment frontier models that often suffer from lack of precision, and for purely stochastic ones that are known to be sensitive to model misspecification....

The recent advancements achieved in the development of a fluid-to-fluid similarity theory for heat transfer with fluids at supercritical pressures are summarised. prime mover was interest Supercritical Water nuclear Reactors (SCWRs) frame research being developed worldwide; however, is general and can be applied to any system involving pressure. steps involved rationale basis discussed presente...

While echocardiography has been used to noninvasively document indirect effects on the heart of left-to-right shunting through a patent ductus arteriosus, no noninvasive technique has been developed to image the duct itself. In this study, 35 sequential studies were performed on 28 patients with a mechanical sector scanner to image the distal pulmonary artery and its bifurcation by scanning alo...

Renewable energy sources include solar, wind, hydro, geothermal and biomass. Furthermore, ocean is being rapidly harnessed worldwide. In this study, to establish a suitable design method for various bidirectional ducted tidal turbines, instead of using blade element momentum theory CFD, which have been used previously, the turbomachinery was designing turbines. A turbine optimises equipment red...
