Mitral annular calcification (MAC) is a common condition of the mitral valve apparatus.A case involving caseous calcification, a rare variant of MAC is presented.This variant which has a benign course can present as an intracardiac mass and needs to be differentiated Display Figure from more sinister causes of calcified cardiac masses such as tumor
In this work, a prescribed-time Miniatures Kit second-order sliding mode (SOSM) controller is constructed to address a class of nonlinear systems in the presence of asymmetric output constraints.To handle the asymmetric constraints, a frequently-used asymmetric barrier Lyapunov function is employed.Meanwhile, a time-varying scaling function is intr
Case Carburized (CC) low carbon steels containing Ni, Cr and Mo alloying elements are widely used for transmission gears in automobile, as it possesses desired mechanical properties.In order to cut cost and save scarce Wooden Dollhouse Accessories materials like Ni and Mo for strategic applications, steel alloyed with Boron has been developed, whic
The unsteady read more mass transfer of the packaging constituents to a food has been analysed.The diffusion coefficient inside the packaging was considered concentration - variable while the food was considered concentration spatially gradientless.A well-known technique (Kirchhoff transformation) Desktop Vaporizers was used to solve the non-linear
