Stable carbon isotope ratios and alkaline earth ratios of enamel carbonate indicate a decline in maize consumption from Preclassic to Classic periods, perhaps due to the desiccation of Lake Miraflores, which was used to irrigate Late Preclassic fields.
If the water found on comets contains an earth-like ratio of deuterium (a form of hydrogen that has a heavy nucleus) to ordinary, light hydrogen, that would favour the plastering theory.
An enhanced magnetostriction is observed with Terfenol-D with higher ratios of the rare earth element Tb/Dy ratio at the same volume fraction of RFe2 due to the increase of magnetocrystalline anisotropy, which is controlled by the Tb/Dy ratio within a crystal (Kwon et al. 2005).
For example, when using Earth Simulator, the ratio of memory bandwidth to the floating-point performance (Byte/Flops ratio; hereinafter B/F ratio) is 4, which makes it easy to execute NICAM with a high degree of efficiency.
Ideally one would simply measure the downward atmospheric neutrino flux and compare it with the upward neutrino flux from the opposite direction and use the ratio Earth-in to Earth-out to measure the density profile in a way that is independent of the intrinsic angular dependence of the atmospheric neutrino beam.
In addition, increasing the burial depth resulted in a slight decrease in the earth pressure coefficient ratio as illustrated in Fig. 8b.
After adjustment for area, age, sex, current smoking, and physical activity, subjects in the Yellow Earth cluster (prevalence ratio 1.22 [95% CI 1.04 1.43]) and New Affluence cluster (2.05 [1.76–2.37]) had significantly higher prevalence rates compared with those for the Green Water cluster.
During these teething years, we have demonstrated the capacity to detect Earth-Moon mass ratio systems in roughly 1 in 6 cases, and Pluto-Charon mass-ratios for 1 in 3. I'll discuss our constraints from initial surveys, exciting secondary science which has resulted from our search and the outlook for the future.
Particularly, an inner core with an Earth-like aspect ratio of β=0.35 is retained in most of the models to ensure consistency with the existing literature regarding Earth and Mars.
