Landforms are natural features on the Earth’s surface that both reflect and shape geophysical and ecological process. The result is a defining part of landscapes that so often impact on human perception and interactions with environment. Blascyznki (1997) defines landforms as, “specific geomorphic features on the surface of the Earth,...
We computed band gaps of amorphous oxides within the In-Ga-Zn triad. These included ZnO, Ga2O3, In2O3, Ga2ZnO4, Ga2Zn8O11, In2ZnO4, InGaZnO4, and InGaO3. Comparing the computed band gap to experimental measurements, the results were promising with a mean unsigned error of 0.28 eV and an unsigned standard deviation of 0.28 eV....
The semi-arid dryland wheat-producing areas of the Pacific Northwest are characterized by cool, moist winters and dry, hot summers. The amount of annual precipitation is generally quite variable and inadequate for annual cropping. Where soil depth is adequate, the predominant loessal soils generally supply sufficient moisture for small grain production...
The first cycle of seismic waves recorded at distances of 45,
300 and 355 km. from the GNOME nuclear explosion was used to determine
whether the near source wave characteristics at 0.3 km.
could be determined from distance measurements. Both head wave
and body wave propagation were considered. First the...
