Operasjon Chromite

, 2016
Amfibielandsettingen i Inchon 15. september 1950 er kanskje det oftest benyttede eksempelet på suksessfull operasjonell manøver. General Douglas MacArthur snudde der en vanskelig situasjon for FN og de sør-koreanske styrkene i Pusan perimeteret til seier over den nord-koreanske arméen, og gjenopprettet grensen ved den 38. breddegrad i løpet av to uker.

Metamorphism on Chromite Ores from the Dobromirtsi Ultramafic Massif, Rhodope Mountains (SE Bulgaria)

Geologica Acta, 2009
Podiform chromitite bodies occur in highly serpentinized peridotites at Dobromirtsi Ultramafic Massif (Rhodope Mountains, southeastern Bulgaria). The ultramafic body is believed to represent a fragment of Palaeozoic ophiolite mantle.

Infrared Spectra of Meteoritic SiC Grains

, 1998
We present here the first infrared spectra of meteoritic SiC grains. The mid-infrared transmission spectra of meteoritic SiC grains isolated from the Murchison meteorite were measured in the wavelength range 2.5--16.5 micron, in order to make available ...

Determination of Anomaly Source Border Using Reweighting Focusing Inversion of Two-Dimensional Gravity Horizontal Gradient Data and Conventional Edge Detection Methods (Case Study: A Chromite Mass in Sabzevar, Iran)

Geofísica Internacional
There are numerous methods to detect the edge of gravity and magnetic field anomaly source, most of which are based on the combination of first and second-order horizontal and vertical gradients of the potential field.

An Overview of H2 and CH4 as Environmentally Sustainable Alternative Reductants to C for Chromite Smelting

Advanced Energy & Sustainability Research
The application of hydrogen (H2) and methane (CH4) as gaseous reductants for pure chromite (FeCr2O4) is reviewed in four theoretical approaches. These approaches are evaluated against the conventional process, where the sole reductant is a solid carbon ...
