This paper proposes a method for performing predictive simulation of cardiac surgery. It applies a hybrid approach to model the deformation of blood vessels. The hybrid blood vessel model consists of a reference Cosserat rod and a surface mesh. The reference Cosserat rod models the blood vessel's global bending, stretching, twisting and shearing in a physically correct manner, and the surface m...

Dystrophin is a large protein involved in the rare genetic disease Duchenne muscular dystrophy (DMD). It functions as a mechanical linker between the cytoskeleton and the sarcolemma, and is able to resist shear stresses during muscle activity. In all, 75% of the dystrophin molecule consists of a large central rod domain made up of 24 repeat units that share high structural homology with spectri...

We discuss the phenomenon of physical aging in a well studied atomic model liquid, a binary mixture of particles interacting with Lennard-Jones potentials. We put emphasis on the different dynamical behaviours of the model as well as on the relations between the experimental and numerical timescales. The physics of aging is discussed within a well characterized thermodynamic framework, based on...

BACKGROUND The aim of this study was to contrast the collapse values of the postoperative weight-bearing areas of different tantalum rod implant positions, fibula implantation, and core decompression model and to investigate the advantages and disadvantages of tantalum rod implantation in different ranges of osteonecrosis in comparison with other methods. MATERIAL AND METHODS The 3D finite el...

In a previous paper the submicroscopic morphology of the outer and inner segments of the rod cell of the adult retina has been described (1). The conclusion was drawn, that the fibrous connection between both segments is constituted by a short cilium, the so called "connecting cilium," which is composed of nine pairs of filaments, a basal body, matrix material, and a surface membrane. The outer...

Cupper oxide nanoparticle (CuO-NPs) has been widely utilized in biomedical application due to their antibacterial function. It is well known that antibacterial characteristics of ma-terials could be controlled using the size, shape and composition of the particles. The aim of this paper is to green synthesis CuO-NPs with various morphologies, using Aloe Vera extract as reducing agent and invest...

Six CMK-n replicas (n = 3, 5, 6, 7, 8, and 9) were synthesized using a new, facile versatile method based on surface-selective deposition of poly(furfuryl alcohol) onto the silica matrix. The concept synthesis relies in situ polycondensation carbon precursor toluene suspension hard template. Preferential pre-adsorption monomer provides even coverage its surface with polymer, which is prerequisi...

Subperiosteal bone-bonding devices have been proposed for less invasive treatments in orthodontics. The device is osseointegrated onto a bone surface without fixation screws and is expected to rapidly attain a bone-bonding strength that successfully meets clinical performance. Hence, the device's optimum shape for rapid and strong bone bonding was examined in this study by finite element analys...
