Magnesium oxideRuminal fermentationDissolved hydrogenDissolved methaneThis study aimed to examine the hypothesis that extra molecular hydrogen (H 2 )produced by elemental magnesium (Mg)could alter rumen fermentation and methanogenesis in in vitro batch incubation. As elevated Mg may exert negative effects ...
We distinguished 10 elements in total: sodium (Na), potassium (K), magnesium (Mg), calcium (Ca), manganese (Mn), aluminum (Al), iron (Fe), phosphorus (P), nitrogen (N) and sulphur (S). All elements except N were determined with ICP-AES (Perkin Elmer, Plasma 2000) after digestion...
A subsample of the ground material was digested in hot nitric acid and the digests were analyzed for calcium (Ca), copper (Cu), potassium (K), magnesium (Mg), phosphorus (P), S and zinc (Zn) by ICP-OES. Preliminary trials had indicated that there was no significant difference in 34S...

An improved olefin disproportionation catalyst produced by contacting an inorganic refractory oxide containing a catalytic amount of molybdenum oxide with a promoting amount of elemental metals of the group consisting of tin and magnesium.Simon G. Kukes...
Direct conversion of hydrogen sulfide to elemental sulfide using sulfated solid oxide(sulfated magnesium aluminate i.e. solid oxide* so3), regenerating the sulfated solid oxidedoi:US5958359 AThis invention is directed to an improved process for conversion of H 2 S to sulfur, using MOST(Mobil ...
Magnesium can be present in illite and mixed-layer clays, but may also be present in chlorite and various carbonates (e.g., calcite, ankerite, and dolomite) or may have organic associations [19,39,40] Lithium, which is most commonly found in aluminosilicates in coal [19], has a strong...
3.3. Magnesium The recommended intake of magnesium during pregnancy is 350 mg/day to maintain function of over 300 enzymes that utilise ATP (Table 1) [6,16]. Leafy green vegetables provide a good source of magnesium, due to its presence in the core of the chlorophyll molecule. Other ...
