A finite strain gradient model for the 3D analysis of materials containing spherical voids is presented. two-scale approach proposed: a least-squares methodology RVE with quadratic displacements and full high-order continuum both fourth-order sixth-order elasticity tensors. meshless method adopted using radial basis function interpolation polynomial enrichment. Both first second derivatives res...

two types of mineralization including porphyry copper and epithermal gold mineralization have occurred in relation with an intermediate volcano-plutonic complex in masjeddaghi area. different alterations including silica, advanced argillic, intermediate argillic and propylitic have been distinguished in relation with epithermal mineralization, which have a zonal pattern. elemental mass gains an...

the noorabad-kermanshah ophiolite is part of eastern mediterranean-zagros-oman tethyan ophiolites, that this area is located in south-southwest of the main zagros thrust fault. this ophiolite consists of peridotites, serpentinites and pegmatite gabbros as mantle sequence whereas crustal sequences are composed of locally layered gabbros, isotropic gabbros, sheeted dike complex, basaltic to andes...

let g be a group. a subset x of g is a set of pairwise noncommuting elements if xy ̸= yx for any two distinct elements x and y in x. if |x| ≥ |y | for any other set of pairwise non-commuting elements y in g, then x is said to be a maximal subset of pairwise non-commuting elements. in this paper we determine the cardinality of a maximal subset of pairwise non-commuting elements in any non-abelian...

Let $G$ be a finite group‎. ‎A subset $X$ of $G$ is a set of pairwise non-commuting elements‎ ‎if any two distinct elements of $X$ do not commute‎. ‎In this paper‎ ‎we determine the maximum size of these subsets in any finite‎ ‎non-abelian metacyclic $2$-group and in any finite non-abelian $p$-group with an abelian maximal subgroup‎.
