A NEW METHOD for deriving rigorous bounds on the effective elastic constants of a composite material is presented and used to derive a number of known as well as some new bounds. The new approach is based on a presentation of those constants as a sum of simple poles. The locations and strengths of the poles are treated as variational parameters, while different kinds of available information ar...

The assessment of proposed origins for thermal conductivity enhancement in nanofluids signifies the importance of particle morphology and coupled transport in determining nanofluid heat conduction and thermal conductivity. The success of developing nanofluids of superior conductivity depends thus very much on our understanding and manipulation of the morphology and the coupled transport. Nanofl...

Objective (s):Rheumatoid arthritis (RA) is a chronic systemic inflammatory disorder, primarily targeting the synovium and articular cartilage that leads to joint damage. Recent reports have suggested the role of adipocytokines in mediating joint damage; however it still is a matter of debate. The purpose of this study was to evaluate the association between serum values of adiopocytokines (lept...

For seismic risk analysis, reliable predictions and estimations of earthquake damage behaviour buildings are essential. A common method is the use fragility curves. In this paper, functions developed based on various numerical criteria for five defined grades, from slight to destruction. The proposed new multiscale approach establishes a correlation between observed patterns due foreign earthqu...

The ellipse assemblage model with imperfect interface has quite complex microstructure, that can be considered an extension of the circle interfaces. paper introduces approximate method for computing effective conductivity isotropic composites interfaces in two-dimensional space. Based on coated-ellipse and equivalent inclusion approximation, one determine thermal composites. polarization appro...
