In an actively deforming orogen, maintenance of a topographic steady state requires that hillslope erosion, river incision, and rock uplift rates are balanced over timescales of 10–10 years. Over shorter times, < 10 years, hillslope erosion and bedrock river incision rates fluctuate with changes in climate. On 10-year timescales, the Marsyandi River in the central Nepal Himalaya has oscillated ...
Density-functional theory calculations are used to study the adsorption and growth of small Li clusters on MgO 100 . The binding of Li is found to be similar to that of Ca in many respects. Monomers bind to oxygen sites on the terrace and diffuse at room temperature to defect sites. A range of defect sites will bind monomers with increasing energies from oxygen vacancies, steps, kinks, divacanc...

Based on X-ray photoelectron spectroscopy, Gd5Ge 4(010) does not show evidence of surface segregation. Scanning tunneling microscopy reveals two types of terraces which alternate laterally on the surface. From the step heights, these two surface terminations are assigned as dense, Gd-pure layers in the bulk structure. There is evidence of reconstruction on one type of terrace.
The Big Bone Lick area in Kentucky, the first widely known collecting locality for vertebrate fossils in North America, is being investigated for further faunal and geologic evidence. Mammal bones, ranging in age from Wisconsin (Tazewell?) to Recent, were recovered in 1962 from four different faunal zones in two terrace fills.

Bicomponent hydrogen-bonded nanostructures formed by two complementary molecular Landers on Au(111).
The co-adsorption of two molecular Landers equipped with functional groups capable of forming a complementary triple hydrogen-bonding motif is investigated with scanning tunneling microscopy and molecular mechanics calculations. Surprisingly, the anticipated complementary motif is not realised in 2-D terrace structures, but is observed in 1-D structures at step edges where molecular conformatio...
Nowadays the use of remote sensing and Geographic Information System (GIS) is one of the most powerful cost effective tools to identify and discover the available groundwater resources. In this paper, Lithological Units, Lineaments, Slope, Topography, Drainage density, Vegetation and Isohyets lines have been achieved by stations and through remote sensing and GIS techniques. All layers of diffe...
Density functional theory is used to calculate the adsorption of Ca adatoms on a MgO 100 surface. The Ca monomer binds preferentially to the oxygen site on the terrace with an adsorption energy of 0.84 eV and diffuses by hopping to a nearest neighboring oxygen site with a barrier of 0.45 eV. The binding at F and F+ oxygen vacancy defects is weaker than on the terrace. Small Ca clusters on the s...
