Boninites are rare high magnesium andesites that often contain trace chromites. These chromites precipitate from primitive boninitic melts and thought to be carried the surface in continue crystallize a significant volume of silicate minerals. Such magmatic differentiation drives chromite out equilibrium with residual melt respect both divalent trivalent cation proportions. Diffusion then opera...

A chromite occurrence called the Sabantuy paleoplacer was discovered in Southern Pre-Ural region, at east edge of East-European Platform transitional zone to Ural Foredeep. ca. 1 m-thick chromite-bearing horizon is traced a depth 0.7–1.5 m from earth’s surface for area 15,000 m2. The chromspinel content sandstones reaches 30–35%, maximum values Cr2O3 are 16–17 wt.%. grain size detrital ranges 0...

context: to evaluate treatment success and hypothyroidism following main methods of radioiodine therapy of toxic nodular goiter (tng); calculated versus fixed dose and high versus low dose of radioiodine. evidence acquisitions: we searched medline and scopus databases from inception till july 2013, for clinical trials that compared two different methods of radioiodine administration in tng. the...

The full rare-earth (RE) chromites series (RE)CrO(3) with an orthorhombic distorted (Pnma) perovskite structure and the isostructural compound YCrO(3) can be synthesized through a simple microwave-assisted technique, yielding high-quality materials. Magnetization measurements evidence that the Néel temperature for antiferromagnetic Cr(3+)-Cr(3+) ordering strongly depends on the RE(3+) ionic rad...

PURPOSE To report a case of epibulbar nodular fasciitis in a 32-year-old female and provide context by reviewing the current literature. RESULTS Using excisional biopsy, the patient was successfully diagnosed and treated for epibulbar nodular fasciitis. Upon follow-up, there has been no recurrence, consistent with the typical course for nodular fasciitis. CONCLUSIONS Epibulbar nodular fasci...

we report two cases of focal nodular hyperplasia in patients following gadoxetic acid (gd-eob-dtpa)-enhanced magnetic resonance imaging confirmed with histopathology. these cases showed an atypical pattern during the delayed-hepatobiliary phase after the injection of gadoxetic acid. one case showed a total defect, and the other showed a peripheral ring-like enhancement without a visible central...
