An improved Metal Solar Wall (MSW) with integrated thermal energy storage is presented in this research. The proposed MSW makes use of two, combined, enhanced heat transfer methods. One the methods characterized by filling tested ducts a commercially available copper Wired Inserts (WI), while other one uses dimpled or sinusoidal shaped duct walls instead plane walls. Ducts having square semi-ci...

Early diagnosis and appropriate treatment of cholangiocarcinoma is problematic. Cross sectional imaging and tumor marker CA 19-9 are not absolutely reliable and tissue sampling is difficult. We present a patient with cholangitis and cystic dilation of intra-hepatic bile ducts that primarily diagnosed as Caroli's disease in imaging and needle biopsy but laparotomy and surgical biopsy revealed ch...

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...

Analytical solutions are presented for laminar fully-developed flow in micro/minichannels of hyperelliptical and regular polygonal cross-sections. The considered geometries cover a wide range of common simply connected shapes including circle, ellipse, rectangle, rhomboid, star-shape, equilateral triangle, square, pentagon, and hexagon. Therefore, the present approach can be considered as a gen...

Ventilation ducts with a high cross-sectional area are frequently built as structural that include inside transversal beams. In this way, the requested is respected, but transverse elements will have big impact on airflow, eventually additional noise and vibration amount of energy wasted across From perspective, aim study to evaluate beams ventilation ducts, analyze different alternatives for a...

Sound transmission through ducts of constant cross section with a uniform inviscid mean flow and a constant acoustic lining (impedance wall) is classically described by a modal expansion, where the modes are eigenfunctions of the corresponding Laplace eigenvalue problem along a duct cross section. A natural extension for ducts with cross section and wall impedance that are varying slowly (compa...

Abstract Cross-sectional imaging modalities including ultrasound (US), magnetic resonance (MR) imaging, and computed tomography (CT) play a critical role in the diagnosis of diseases biliary tract gallbladder. Biliary for evaluation obstructive jaundice seeks to diagnose level obstruction its cause. The identification dilated bile ducts necessitates strictures or filling defects, which is best ...

Particles suspended in fluid flow through a closed duct can focus to specific stable locations the cross-section due hydrodynamic forces arising from inertia of disturbed fluid. Such particle focusing is exploited biomedical and industrial technologies separate particles by size. In curved ducts, result balance between two dominant on particle: (i) inertial lift small fluid, (ii) drag cross-sec...
