In the present paper, the free vibration characteristics of nanobeams embedded in an elastic medium are investigated. Inclusion of size effects is considered in the analysis by incorporating Eringen’s nonlocal elasticity continuum into the classical Euler–Bernoulli beam theory. To include the surrounding elastic medium, the Pasternak elastic foundation model is utilized, including shear deforma...

Abstract A mathematical model for nonlocal vibration and buckling of embedded two-dimensional (2D) decagonal quasicrystal (QC) layered nanoplates is proposed. The Pasternak-type foundation used to simulate the interaction between elastic medium. exact solutions frequency critical load 2D QC are obtained by solving eigensystem using propagator matrix method. present three-dimensional (3D) soluti...

Damped curvature oscillations are excited at the surface between a nematic liquid crystal and a solid substrate, from the linear coupling of an AC electric field with the flexoelectric properties of the medium. The waves are detected by a modulation ellipsometry technique. Linear-in-field oscillations of the director in the surface nematic layer have been observed. The amplitude and characteris...

PURPOSE To compare combined viscocanalostomy-trabeculectomy (VISCO-TRAB) to trabeculectomy (TRAB) for the management of advanced glaucoma. MATERIALS AND METHODS The study cohort comprised of 18 subjects with bilateral advanced glaucoma who underwent VISCO-TRAB surgery (VISCO-TRAB group) in the right eye and TRAB (TRAB group) in the left eye. VISCO-TRAB constituted lamellar scleral flap, deep ...

Commonly used polymer-based scaffolds often lack visco-elastic properties to serve as a replacement for cartilage tissue. This study explores the effect of reinforcement of silk matrix with chitosan microparticles to create a visco-elastic matrix that could support the redifferentiation of expanded chondrocytes. Goat chondrocytes produced collagen type II and glycosaminoglycan (GAG)-enriched ma...

The role of non-covalent interactions in the formation of visco-elastic material from zein was investigated. Hydrophobic interactions were evaluated through the addition of various salts from the Hofmeister series. Urea, ethanol, and beta mercaptoethanol (β-ME) were used to evaluate the effects of protein denaturation and disulfide bonds on zein's ability to form a visco-elastic material. The a...
