Background: Cholangiocarcinoma is a cancer of the bile duct epithelium that originates from the bile ducts inside or outside the liver. Although this tumor is not common, its mortality rate is high. This tumor accounts for about 3% of all gastrointestinal malignancies. Many patients are being detected when the disease has spread. Evaluating risk factors affecting the incidence of cholangiocarci...

Background: Rupture into the biliary ducts is the most frequent complication of hydatid liver disease. In endemic areas of Echinococcus granulosus, development of jaundice in a patient with liver cyst is initially suspected to have hydatid cyst. Case Presentation: A 48 year-old woman with history of asymptomatic hydatid liver cysts was admitted to the emergency department with right upper qu...

We examine the effect of Dean number on inertial focusing spherical particles suspended in flow through curved microfluidic ducts. Previous modelling particle migration ducts assumed rate was small enough that a leading-order approximation background with respect to produces reasonable model. Herein, we extend our model situations involving moderate (in microfluidics context) while Reynolds rem...

Copper nickel indium (CuNiIn) and Molybdenum disulphide (MoS2) duplex coating is used in aero engine compressor blades of Ti6Al4V to prevent fretting failure. Surface before roughened by grit blasting process for adhesion. In present study, place blasting, laser surface texturing (LST) preparation compared with blasted surface. Four different elliptical square patterns are created LST on Ti6Al4...

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).

Cement cracks are one of the most common failures in oil and gas wells. Cracks can reduce cement strength, resulting a loss zonal isolation fluid leak. Placement gels nanoparticles (NPs) is considered as promising solution to solve problem. It highly desirable know if flow behavior NPs solutions predictable when they squeezed into cracks. Experimental tests were performed this study investigate...

Analytical solutions are presented for velocity and temperature distributions of laminar fully developed flow of Newtonian, constant property fluids in micro/minichannels for a wide variety of cross-sections. The considered geometries include hyper-elliptical channels and regular polygon ducts, which covers several common shapes. The analysis is carried out under the conditions of constant axia...
