The valves of oysters act as a physical barrier between tissues and the external environment, thereby protecting the oyster from environmental stress and predation. To better understand differences in shell properties and predation susceptibilities of two physiologically and morphologically similar oysters, Crassostrea virginica and Crassostrea ariakensis, we quantified and compared two mechani...

There have been numerous researchers that have investigated the properties of human intervertebral discs. However, there has been no attempt to characterize the effects of dynamic loading on the compressive stiffness of human lumbar intervertebral discs. Therefore, the purpose of this study was to develop the compressive stiffness properties of lumbar intervertebral discs when subjected to vari...

The Aim of present investigations is to evaluate the physical property-water absorptions and mechanical property-compressive properties. Coconut particle reinforced composites were fabricated by reinforcing shell particle (size between 200-800μm) by wt% of 20, 25, 30 & 35 into epoxy matrix. Composites plates were made by casting in open mould. That is possible with very low cost and easy way. E...

Microscopic hydrogel spheres can be used to improve the mechanical properties of conventional hydrogels. We prepared ionic-covalent entanglement (ICE) hydrogel microspheres of calcium cross-linked gellan gum and genipin cross-linked gelatin using a water-in-oil emulsion-based processing technique. The method was optimized to produce microspheres with number average diameter 4 ± 1 μm. These ICE ...

With many years of construction and application of common concrete, researchers have always been searching for a better composition. One of the notable ideas for achieving such a composition is using recycled materials. One of the materials which is suitable for environment and constant development is damaged tires .For studying mechanical properties of concrete containing tire particles, a ser...

in this work, we studied the effect of carboxylic acid on the rheological properties of a high-alumina cement mortar (ch45) produced by the algerian firm refractal.the investigated properties are setting time, water consumption, electrical conductivity, ph, density and the compressive strength. the results show a setting time of about 200 min for the acid free, 180 min with 0.1 % of carboxylic ...

Magnetic shape memory properties of Ni-Mn-Ga single crystals were characterized by measurement of stress-induced martensite reorientation under constant magnetic fields. Also magnetic field-induced strain as a function of the applied magnetic field under different constant compressive stress levels has been investigated. All the experiments were performed at room temperature in which the sample...
