Young’s Modulus and Poisson’s Ratio of Monolayer Graphyne
Despite its numerous potential applications, two-dimensional monolayer graphyne, a novel form of carbon allotropes with sp and sp2 carbon atoms, has received little attention so far, perhaps as a result of its unknown properties. Especially, determination of the exact values of its elastic properties can pave the way for future studies on this nanostructure. Hence, this article descr...
متن کاملA Study on Ratio of Loss to Storage Modulus for the Blood Clot
In this study the rheology of blood clot is measured with the help of rotational rheometer. Several shear strain (0.5, 1 and 2%) are applied with two frequencies (5 and 10 Hz) from the incipient time of clot formation and the response of the sample is measured with the form of shear stress and the phase lag which is interpreted with storage and loss moduli. In this study the ratio of loss to st...

متن کاملPerformance analysis of drilling machines using rock modulus ratio
Rotary drills, diamond drills and percussive drills have been extensively used in open pits, quarries and construction sites. The prediction of the penetration rate of drilling machines is very important in the cost estimation and the planning of the rock excavation projects. The rock modulus ratio, which is the ratio of elastic modulus to compressive strength, indicating the deformability, is ...
متن کاملReduced Simple Ratio Better than NDVI for Estimating LAI in Finnish Pine and Spruce Stands
Estimation of leaf area index (LAI) using spectral vegetation indices (SVIs) was studied based on data from 683 plots on two Scots pine and Norway spruce dominated sites in Finland. The SVIs studied included the normalised difference vegetation index (NDVI), the simple ratio (SR), and the reduced simple ratio (RSR), and were calculated from Landsat ETM images of the two sites. Regular grids of ...
