‎Let $tau$ be a subgroup functor and $H$ a $p$-subgroup of a finite group $G$‎. ‎Let $bar{G}=G/H_{G}$ and $bar{H}=H/H_{G}$‎. ‎We say that $H$ is $Phi$-$tau$-quasinormal in $G$ if for some $S$-quasinormal subgroup $bar{T}$ of $bar{G}$ and some $tau$-subgroup $bar{S}$ of $bar{G}$ contained in $bar{H}$‎, ‎$bar{H}bar{T}$ is $S$-quasinormal in $bar{G}$ and $bar{H}capbar{T}leq bar{S}Phi(bar{H})$‎. ‎I...

In this study, the applicability of nanofiltration (NF) membranes as a pretreatment prior to reverse osmosis (RO) in seawater desalination was investigated. The membranes used wereNF270 and NF90 as the NF membranes, while the brackish water (BW) RO membrane BW30 was used as the RO membrane. In desalination tests, permeates of the NF membraneswere collected and used as the feed to th...

in his paper the effect of ribbing in bending and tortional resisance of the box type structure is discussed . for satisfactory design of press structures . the stiffness characteristics of individual components are recognised to be of primary importance. heavy press stucures are normaly constructed in double-sided form . because of transportation and handing problems , these frames are usually...

The problems of the uneven strip shape and low efficiency tea de-enzyming carding machines in working process were addressed by analyzing trajectory particles establishing a force model diagram pot slot. three-dimensional geometric machine was drawn using UG software, simulation established EDEM software. work improved, rate broken reduced software to simulate movement slot under different heig...

Peter Kilroy King’s College London London, UK Abstract Drawing on the ields of postcolonial studies and media theory, this article analyzes Frances Calvert’s 1990 documentary, Talking Broken, which, inter alia, looks at the role of space, place and media amongst Australia’s “other” Indigenous community, Torres Strait Islanders. he article explores the historical and geographical complexity of t...
