Leading edge cooling cavities in modern gas turbine airfoils play an important role in maintaining the leading edge temperature at levels consistent with airfoil design life. These cavities often have a complex cross-sectional shape to be compatible with the external contour of the blade at the leading edge. Furthermore, to enhance the heat transfer coefficient in these cavities, they are often...

A new CFRP-aluminum joining method has been developed by Cu electrodeposition. deposition was filled into the roughened CFRP surface and significant anchor effect attained method. As a result, A6061 Al alloy were successfully joined electrodeposition high strength of 67 MPa obtained.

The remarkable enhancement of Raman signals from molecules on roughened silver surfaces or on silver colloids has made it possible to obtain vibrational spectra with only monolayer and submonolayer coverage. This communication discusses the physical notions underlying this phenomenon and then surveys the as yet limited applications to macromolecules.

A new species of the plant bug tribe Mirini representing a new genus, Fangumellus flavobadius, is described from Laos. This genus is characterized primarily by the medium-sized, ovoid, tumid body, less shiny, roughened, almost impunctate dorsal surface, short antenna and labium, short pygophore, and atypical shape of parameres and endosoma. The phylogenetic relationship to other known mirine ge...

Purpose: The aim of this study was to investigate the influence of nicotine and cotinine, two major components of tobacco, on fungal biofilm formation on two acrylic resins. Additionally, the nystatin susceptibility of the planktonic and biofilm fungal cells was compared. Materials and Method: Ivocap and Lucitone 199 polished and roughened acrylic resin discs were fabricated and randomly assign...

formation of hydraulic jump is necessary for dissipation of the excess kinetic energy downstream of spillways and gates. hydraulic jump stilling basins of sudden expansion are one of the energy dissipater structures which are used where the available tail water depth is less than the required sequent depths. in the present study to further reduce the hydraulic jump sequent depths ratio, a rough...
