different samples have been prepared from different products in chadormalu iron ore concentrator plant: low intensity magnetite separators concentrate (magnetite concentrate), reverse flotation tail (final hematite concentrate), flotation concentrate (apatite concentrate), final tail (l.i.m.s. tail + reverse flotation concentrate+ apatite flotation tail). the samples were used for rare earth el...

In this paper we study graded Bourbaki ideals. It is a well-known fact that for torsionfree modules over Noetherian normal domains, sequences exist. We give criteria in terms of certain attached matrices homomorphism to induce sequence. Special attention given sequences. the second part paper, apply these results Koszul cycles residue class field and determine particular ideals explicitly. also...

Abstract. A case of the matrix Kummer relation of Herz (1955) based on the Pearson VII type matrix model is derived in this paper. As a con- sequence, the polynomial Pearson VII configuration density is obtained and this sets the corresponding exact inference as a solvable aspect in shape theory. An application in postcode recognition, including a nu- merical comparison between the exact poly...

MOTIVATION Comparison of multimegabase genomic DNA sequences is a popular technique for finding and annotating conserved genome features. Performing such comparisons entails finding many short local alignments between sequences up to tens of megabases in length. To process such long sequences efficiently, existing algorithms find alignments by expanding around short runs of matching bases with ...

The migration and spatial distribution characteristics of topsoil rare earth elements (REEs) are significant for the risk assessment external environment. However, REEs in ion-adsorption type element (REE) mining areas is poorly studied. We aimed to determine differences control factors typical mines South Jiangxi, China. Sixty-five samples eighteen profile were collected analyzed their content...
