In studying of the in situ gravitational concentration process part feature for placer, the technological ability to transform the in situ massif placer structure is evident. The two main processes involved in altering the massif in situ have been examined and outlined in detail. The in situ disintegration of massif material results in a new massif gravitational stratification structure. Regula...

The reduction of V2O5 and WO3 with hydrogen, the latter which is performed industrially in rotary kilns under a hydrogen countercurrent, has been investigated by using situ X-ray powder diffraction. This method yields insights into processes illustrated transparent section furnace, thus gaining information about reaction pathways as well compositions structures intermediates. More can be found ...

This paper presents a new algorithm that arrives at a generalized solution for the generation of restricted weak compositions of n-parts. In particular, this generalized algorithm covers many commonly sought compositions such as bounded compositions, restricted compositions, weak compositions, and restricted part compositions. Introduced is an algorithm for generating generalized types of restr...

qeysar aminpour (1959-2007) is one of the outstanding figures in contemporary persian poetry. one of the prominent aspects of his poetic style is the distinct language of his poems in the three areas of lexicon, compositions and syntax. relying on these three areas, this study attempted to investigate the most important linguistic features of his poetry in order to figure out special style of t...

Environmental issues regarding Cr6+ formation lead to replacing chrome-containing refractories with greener alternatives. MgO-containing compositions have been extensively investigated for this purpose, however, few studies evaluated the likelihood of using other chemical elements as inducers spinel-like phase in refractory castables. In study, addition zincite alumina-based castables was and c...

despite the great potential of graphene as a nanofiller, achieving homogeneous dispersion remains the key challenge for effectively reinforcing polyolefin (such as polyethylene (pe) and polypropylene (pp)) nanocomposites. therefore, in this research, we report a facile combined in situ polymerization and masterbatch method for fabricating pp/reduced graphene oxide (rgo) nanocomposites. in the p...
