PURPOSE This in vitro study sought to compare the antifungal activity of melaleuca alternifolia oil and fluconazole mixed with a tissue conditioner. MATERIALS AND METHODS By testing several concentrations of fluconazole and melaleuca oil in Visco-gel, the minimum most effective concentration of each antifungal agent against Candida albicans was determined. Mean inhibition diameter (MID) was u...

in this paper, nonlinear vibration and instability response of an embedded pipe conveying viscose fluid is investigated. the pipe is considered as a timoshenko beam embedded on an elastic foundation which is simulated by spring constant of the winkler-model and the shear constant of the pasternak-model. the external flow force, acting on the beam in the direction of the flexural displacement is...

The mucins of sheep colonic mucosa, like other epithelial secretions, are members of the group of 'neutral' niucosubstances (Werner, 1953; Kent, 1962). These characteristically contain L-fucose, D-galactose, N-acetylamino sugars and frequently sialic acids and mannose (Gottschalk, 1960). Their chemical structure and the nature of the sugarpeptide links involved have not yet been established. Pr...

Detailed displacements of [3H]dihydromorphine by ketocyclazocine and SKF 10,047, [3H]ethylketocyclazocine by SKF 10,047, and C3H]SKF 10,047 by ketocyclazocine are all multiphasic, suggesting multiple binding sites. After treating brain tissue in vitro with naloxazone, all displacements lose the initial inhibition of 3H-ligand binding by low concentrations of unlabeled drugs. Together with Scatc...

The bending and free vibration of porous functionally graded (PFG) beams resting on elastic foundations are analyzed. material features the PFG beam assumed to vary continuously through thickness according volume fraction components. foundation medium is also considered be linear, homogeneous, isotropic, modeled using Winkler-Pasternak law. hyperbolic shear deformation theory applied for kinema...

Third order shear deformation theory of cylindrical shells is employed to investigate the vibration characteristics of non-homogeneous cylindrical shells surrounded by an elastic medium. The kinematic relations are obtained using the strain-displacement relations of Donnell shell theory. The shell properties are considered to be dependent on both position and thermal environment. A suitable fun...

In this paper, the nonlinear dynamic buckling of double-walled boron-nitride nanotube (DWBNNT) conveying viscous fluid is investigated based on Eringen's theory. BNNT is modeled as an Euler-Bernoulli beam and is subjected to combine mechanical, electrical and thermal loading. The effect of viscosity on fluid-BNNT interaction is considered based on Navier-Stokes relation. The van der Waals (vdW)...
