We have studied theoretically, using density functional theory, several material properties when going from one C layer in graphene to two and three graphene layers and on to graphite. The properties we have focused on are the elastic constants, electronic structure (energy bands and density of states), and the dielectric properties. For any of the properties we have investigated the modificati...

An elastic anomaly, observed in the heavy Fermi liquid state of Ce alloys (for example, CeCu6 and CeTe), is analyzed by using the infinite-U Anderson lattice model. Four atomic energy levels are assumed for f-electrons. Two of them are mutually degenerate. A small crystalline splitting 2∆ is assumed between two energy levels. Fourfold degenerate conduction bands are also considered. We solve th...

Results: It is demonstrated that higher compression pressure over the calf without increasing the pressure during muscle relaxation is essential to increase the ejection fraction of the calf pump. This may be achieved by applying stiff Velcro-bands or patches around the calf which do not give way when the muscles contract. . A pressure gradient from distal to proximal may be neglected and even ...

Compressive properties of elastic cellular solids are studied via experiments upon foam and upon single-cell models. Open-cell foam exhibits a monotonic stress-strain relation with a plateau region; deformation is localized in transverse bands. Single-cell models exhibit a force-deformation relation which is not monotonic. In view of recent concepts of the continuum theory of elasticity, the ba...

Epidemiological studies show that regular exercise sessions are the most important pillars in the field of cardiologic rehabilitation [6]. For many diseases a correctly implemented strength training therapy can improve physical fitness and health. In this work a novel visual strength measurement method for home-based training was developed. In order to reduce the risk of injury during the train...

Background: Low-grade inflammation can be present in chronic obstructive pulmonary disease (COPD), which may affect the regulation of muscle protein and body metabolism. Regular exercise show improvement in muscle strength and dyspnea in patients with COPD, however, the response to training on inflammatory and metabolic disorders is unclear. In this study, we compared the effects of resistance ...

in the current paper, finite element method is employed for numerical simulations and the study of influential parameters on elastic modulus of polymer-matrix nano-composites. effects of different key parameters including particle elastic modulus, interphase elastic modulus, matrix elastic modulus, interphase thickness and particle volume fraction on total elastic modulus of nano-composite mate...
