Although it has been qualitatively demonstrated that surface roughness can reduce the thermal conductivity of crystalline Si nanowires (SiNWs), the underlying reasons remain unknown and warrant quantitative studies and analysis. In this work, vapor-liquid-solid (VLS) grown SiNWs were controllably roughened and then thoroughly characterized with transmission electron microscopy to obtain detaile...

  SUMMARY Scolicidal agents are used by most surgeons during operations for hydatid cysts when these agents are injected into the cys t cavity, they can pass through the communicating passages between the cyst and bile ducts into the large intrahepatic and extrahepatic bile ducts and because of their caustic nature, they have the potential to damage the epithelium of ducts. This epithelial da...

Introduction: Dicrocoeliasis is a common disease of bile ducts and gallbladder of domestic and wild ruminants. This disease is caused by different species of dicrocoelium including Dicrocoelium dendriticum. The aim of this study was to identify pathological damages and molecular features associated with this parasite in ruminants. Materials and Methods: In this cross-sectional study, 180 fresh...

In current study, flow behavior and heat transfer properties in a square channel roughened with square, right triangle, isosceles triangle circular ribs were examined. The validation test was performed for an experimental rib case pitch ratio (P/e) of 9 blockage (e/H) 0.1. Only to examine the shape factor; height, base width, spacing taken same all cases. study investigated effect various shape...

The initial stages of oxidation on roughened Cu(1 1 0) surface were explored by an in situ ultra-high vacuum transmission electron microscope (UHV-TEM). The dynamic observation of the nucleation and growth of Cu oxide islands shows a highly enhanced nucleation rate on the roughened Cu(1 1 0) surface. The kinetic data obtained from the initial stages of the oxidation indicate that oxygen surface...

This paper reports the preliminary finding that the unique surface morphologies of avian red blood cells (aRBCs) infected by the malaria parasite Plasmodium gallinaceum enables the cells to interact with the roughened surface and become immobilized inside the microfluidic channels. It is also found that a roughened glass substrate with ten-pointheight larger than the depth of surface lesions an...

A microfluidic platform is designed, fabricated, tested, and demonstrated that the unique surface morphologies of avian red blood cells (aRBCs) infected by the malaria parasite Plasmodium gallinaceum enables the cells to interact with the roughened surface and become immobilized inside the microfluidic channels. It is also found that a roughened glass substrate with ten-point-height larger than...
