Objectives: To compare two different dual-curing resins cement interfaces between low translucency and high translucency lithium disilicate glass-ceramics in vitro. M~aterials and Methods: ISO 11405 was modeled by using a standardized dumb-bell test to compare the tensile bond strength of two different resin cement interfaces ofa low translucency lithium disilicate ceramic to a high translucenc...

PURPOSE This study was designed to assess the mechanical properties of two calcium carbonate tempers, limestone and burnt shell. These tempers have been previously compared, in separate studies, to silicate-based grit or sand temper and, relative to the latter, are assumed to possess similar mechanical properties. However, their simultaneous use at the Morrison Village site begs the question: d...

with the aim of identifying failure mechanism in oriented strand boards, failure behavior of wood strands under tensile load was investigated using acoustic emission technique. resinated and unresinated strands were arranged at top, middle and bottom section of the board before pressing. tensile and acoustic emission tests were performed simultaneously on treated and control samples. using tens...

influences of temperature as well as holding time on physical and mechanical properties of fir wood were studied in this work during the oleothermal wood modification. wood samples were cut and treated oleothermally in the soybean oil at 200 and 230°c for the holding time of 1, 3 and 5 hours. weights and the dimensions were measured before and after treatment. bending strengths, water absorptio...

based on three-dimensional theory of elasticity, static analysis of functionally graded carbon nanotube reinforced composite (fg-cntrc) cylindrical panel subjected to mechanical uniformed load with simply supported boundary conditions is carried out. in the process, stress and displacement fields are expanded according to the fourier series along the axial and circumferential coordinates. from ...

Under several emerging application scenarios, such as in smart cities, operational monitoring of large infrastructure, wearable assistance, and Internet of Things, continuous data streams must be processed under very short delays. Several solutions, including multiple software engines, have been developed for processing unbounded data streams in a scalable and efficient manner. More recently, a...

In this talk I assert that the usual interpretation of what one means by “elasticity” is much too insular and illustrate my thesis by introducing implicit constitutive theories that can describe the nondissipative response of solids. I show that response which was hitherto untenable within the context of Cauchy or Green Elasticity are not only possible, they can explain phenomena that have thus...

Spider silk possesses a unique combination of high tensile strength and elasticity resulting in extraordinarily tough fibers, compared with the best synthetic materials. However, the potential application of spider silk and biomimetic fibers depends upon retention of their high performance under a variety of conditions. Here, we report on changes in the mechanical properties of dragline and cap...

Many bacteria and eukaryotic cells express adhesive proteins at the end of tethers that elongate reversibly at constant or near constant force, which we refer to as yielding elasticity. Here we address the function of yielding elastic adhesive tethers with Escherichia coli bacteria as a model for cell adhesion, using a combination of experiments and simulations. The adhesive bond kinetics and t...

nowadays generation capacity in traditional grid depends on fossil fuels and contributes significantly to the increase of pollution emission. in deregulated grids in addition to using demand response programs (drps) to reducing the cost of electricity production, peak clipping and improve reliability use of green plants such as hydro plant, wind plant become widespread. in a smart grid, end use...
