Advances in Understanding of the Application of Unit Operations in Metallurgy of Rare Earth Elements

open access: yesMetals, 2021
Unit operations (UO) are mostly used in non-ferrous extractive metallurgy (NFEM) and usually separated into three categories: (1) hydrometallurgy (leaching under atmospheric and high pressure conditions, mixing of solution with gas and mechanical parts ...

Singularities of the Ruled Surfaces According to RM Frame and Natural Lift Curves

open access: yesCumhuriyet Science Journal, 2022
In this study, the ruled surface generated by the natural lift curve in IR^3 is obtained by using the isomorphism between unit dual sphere, DS^2 and the subset of the tangent bundle of unit 2-sphere, T\bar{M}. Then, exploitting E.

New 3-bar prismatic tensegrity units [PDF]

open access: yesComposite Structures, 2018
Abstract Various methods have been presented for generating complex tensegrity structures by assembling simple units. Hence, generating new units will in turn benefit in obtaining various shapes of tensegrity structures. In this paper, we present three different new units by adding strings to the well-known 3-bar prismatic tensegrity unit. Analytical

Compression and ablation of the photo-irradiated molecular cloud the Orion Bar [PDF]

open access: yesNature, 2016
The Orion Bar is the archetypal edge-on molecular cloud surface illuminated by strong ultraviolet radiation from nearby massive stars. Our relative closeness to the Orion nebula (about 1,350 light years away from Earth) means that we can study the ...

Unit bar architecture in a highly‐variable fluvial discharge regime: Examples from the Burdekin River, Australia

open access: yesSedimentology, 2019
Unit bars are relatively large bedforms that develop in rivers over a wide range of climatic regimes. Unit bars formed within the highly‐variable discharge Burdekin River in Queensland, Australia, were examined over three field campaigns between 2015 and
