The period-ratio and mass-ratio correlation in extra-solar multiple planetary systems [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2015 Abstract Employing the data from orbital periods and masses of extra-solar planets in 166 multiple planetary systems, the period ratio and mass ratio of adjacent planet pairs are studied. The correlation between the period ratio and mass ratio is confirmed, with a correlation coefficient of 0.5303 with a 99 per cent confidence interval ...

Effective role of CaO/P2O5 ratio on SiO2-CaO-P2O5 glass system
Journal of Advanced Research, 2017 In the present work, the effect of the CaO/P2O5 ratio on the composition of sol-gel synthesized 58SiO2-(19 − x)P2O5–(23 + x)CaO (x = 0, 5, 10 and 15 mol%) glass samples was studied. Further, the effect of NBO/BO ratio on hydroxy carbonated apatite layer (

The Labor/Land Ratio and India's Caste System [PDF]
SSRN Electronic Journal, 2012 This paper proposes that India's caste system and involuntary labor were joint responses by a nonworking landowning class to a low labor/land ratio in which the rules of the caste system supported the institution of involuntary labor. The hypothesis is tested in two ways: longitudinally, with data from ancient religious texts, and cross-sectionally ...

Poisson’s ratio of anisotropic systems [PDF]
Computational Methods in Science and Technology, 2005 The Poisson’s ratio of anisotropic materials depends, in general, both on a “longitudinal” direction along which the stress is changed and on a “transverse” direction in which the transverse deformation is measured. For cubic media there exist “longitudinal” directions, parallel to the 4-fold and 3-fold axes, for which the Poisson’s ratio does not ...
