The Neoproterozoic Nagarparkar Complex is characterized by isolated semicircular hillocks of outcrops of “withinplate” A-type peralkaline to peraluminous granites. Geochemically the granites/rhyolites of the Nagarparkar Complex are characterized by high SiO2, Na2O+K2O, K2O, Fe/Mg, Al2O3, Zr, Nb and Y and low CaO and Sr. Majority of samples show moderate iron enrichment. The rocks show the chara...

The catalytic oxidation of sulfur dioxide to sulfur trioxide over several binary (MxOy/TiO2) and ternary (V2O5/MXOY/TiO2) supported metal oxide catalysts was systematically investigated. The supported metal oxide components were essentially 100% dispersed as surface metal oxide species, as confirmed by Raman spectroscopy characterization. The sulfur dioxide oxidation turnover frequencies of the...

A field experiment was conducted to study the response of wheat and rice to potassium during 2004-05. The basal dose of N at 120 kg, P2O5 at 90 kg ha -1 was applied with K levels to both wheat and rice crops. Wheat variety Naseer 2000 and rice variety IRRI 6 were used in the study. The experiment was carried out in R.C.B design with three replications. Potassium application significantly increa...

Layered, binary thin-film oxides of NiO, MgO and CaO have been prepared and characterized using low energy electron diffraction, Auger electron spectroscopy, energy loss spectroscopy, ion scattering spectroscopy, and temperature programmed desorption using probe molecules. Epitaxial growth was observed for the NiO–MgO and CaO–NiO systems; however, superior wetting was found for NiO–MgO relative...

Two experiments were conducted to determine the effect of increasing dietary CaO on ruminal fermentation, diet digestibility, performance, and carcass characteristics of feedlot steers fed 60% dried distillers grains with solubles ( DDGS: ). In Exp. 1, 120 steers were allotted by weight (355 ± 7.9 kg) to 1 of 4 treatments containing 60% DDGS, 20% corn silage, 13.5 to 14.4% ground corn, 4% suppl...

Significant zonation in major, minor, trace, and volatile elements has been documented in naturally glassy olivine-hosted melt inclusions from the Siqueiros Fracture Zone and the Galapagos Islands. Components with a higher concentration in the host olivine than in the melt (e.g., MgO, FeO, Cr2O3, and MnO) are depleted at the edges of the zoned melt inclusions relative to their centers, whereas ...
