Abstract The task of finding the potential a thin circular disk with power-law radial density profile is revisited. result, given in terms infinite Legendre-type series above reference, has now been obtained closed form thanks to method Conway employing Bessel functions. Starting from closed-form expression for generated by elementary term ρ 2 l , we cover more generic—finite solid or annular—t...

Porokeratoses are uncommon hereditary or acquired keratinization disorders due to abnormal clones of keratinocytes in the epidermis. Porokeratoses have several clinical features which may occur simultaneously. A rare type is verrucous porokeratosis (VPK). Herein, we present a 47-year-old man with a 4-year history of perianal verrucous lesions and one year history of annular pruritic lesions on ...

In the present article, buckling analysis of functionally graded annular thin and moderately thick plates under mechanical and thermal loads is investigated. The equilibrium and stability equations of the plate are obtained based on both classical and first order shear deformation plate theories. By using an analytical method, the coupled stability equations are converted to independent equatio...
